Description

Disposable container {DISPOSABLE CONTAINER}

The present invention relates to a container having an integral folding structure, and more particularly, it is configured to change the volume of the accommodation space provided by the container, and the folding structure is unfolded and used during use, thereby maintaining a reduced volume during storage. It relates to a container having an integral folding structure.

Disposable products mean items that are discarded after being used once. With the recent increase in national income, convenience of life is important, and the use of disposable products is increasing. Bowls and containers used in everyday life can also be examples of disposable items.

As a specific example of a disposable container used in daily life, a container in which simple cooking meals such as cup noodles and cup rice are accommodated may be mentioned. An article in a form in which food is accommodated in a disposable container, that is, an instant food, is packaged in a state in which food in a frozen or dried state is accommodated so that food can be conveniently cooked therein, and is configured to allow a user to pour hot water and consume. Instant food can be easily cooked in a short time, storage or preservation is simple, and transportation and portability are convenient. Accordingly, in the case of outdoor activities such as travel, mountain climbing, and trekking, convenience foods that are convenient for transportation and portability for cooking are sometimes brought with them.

However, in the conventional instant food, since it is common to cook food by pouring hot water, the disposable container has an excessively large volume compared to the volume of the internal food. That is, even if the conventional instant food is known to be relatively portable, the large volume of the disposable device still remains a problem, and there is ample room for improvement.

The inventors of the present invention came to complete the present invention by paying attention to the problem of the conventional disposable container described above. In other words, for the complete cooking and consumption of simple cooked food, the container needs to provide a sufficient internal storage space, but because the simple cooked food inside is frozen or dried and stored, the disposable container accommodates too large a volume of the internal food They have space. Therefore, if the volume of the internal accommodation space of the disposable container can be varied, the above problem can be solved.

On the other hand, since disposable containers are discarded after being used once, manufacturing cost and product price can act as very important factors for commercialization. In particular, when a disposable container is used for a purpose of accommodating food, there is an urgent need to develop a disposable container that can be provided at a lower cost because the price of the food itself is not high.

Accordingly, a problem to be solved in the present invention is to provide a container having a folding structure and having a variable volume of the internal accommodation space.

1 to 3, the container 10 according to the present embodiment has an open upper portion, and is folded by being coupled to the lower end of the container body portion 110 and the container body portion 110 forming a main sidewall. It may include a folding portion 200 to maintain the state. In addition, in some embodiments, it may further include a container cover 300 disposed on the upper end of the container body portion 110.

Although not shown in the drawings, contents (not shown) may be accommodated in the inner space formed by the container body portion 110 and the folding portion 200. The contents may include food, household goods, waste, and the like. For a specific example, the food may be frozen or dried simple cooked food such as instant noodles, dried soup, liquid soup, dumplings, dried rice, cereal, etc., cooked and packaged retort food, or simple cooked food in an uncooked state, The container 10 containing food may be a disposable container. However, of course, the present invention is not limited thereto.

The container body portion 110 and the folding portion 200 may be made of paper or synthetic resin, respectively.

Through this, the first folding part 210, the second folding part 220, the third folding part 230, and the fourth folding part 240 each at least partially form the bottom of the container 10, Can contribute to forming part.

In a plan view, the first folding part 210, the second folding part 220, the third folding part 230, and the fourth folding part 240 may be folded to be visually recognized in a substantially triangular shape, respectively. The first folding part 210 and the third folding part 230 may face each other, and the second folding part 220 and the fourth folding part 240 may face each other. More specifically, the second folding part 220 and the fourth folding part 240 may be positioned to be overlapped below the first folding part 210 and the third folding part 230.

The first folding part 210, the second folding part 220, the third folding part 230, and the fourth folding part 240 may each have a folding structure, specifically, a convex or concave folding line. The first folding part 210, the second folding part 220, the third folding part 230, and the fourth folding part 240 may be folded along the folding line to maintain the folded state from the initial state. The folding structure of the first folding part 210, the second folding part 220, the third folding part 230, and the fourth folding part 240 will be described later in detail with reference to FIG. 4 and the like.

In addition, the folding part 200 may further include a bottom part 250. The bottom portion 250 may be a portion that forms a substantially bottom of the container when the container is fully unfolded, as will be described later. The bottom part 250 may contact the first folding part 210, the second folding part 220, the third folding part 230, and the fourth folding part 240 to share a side.

When viewing the container 10 in the folded state from the bottom, the first folding part 210, the second folding part 220, the third folding part 230, and the fourth folding part 240 Is an approximately square shape, and the bottom portion 250 may also have an approximately square shape. In this case, in a plan view, the size of the square formed by the first folding part 210, the second folding part 220, the third folding part 230, and the fourth folding part 240 is the bottom part 250 Can be larger than the size of As will be described later, when the container is fully unfolded, the inner surface of the container may have a downwardly inclined shape so that the width and size of the container decreases toward the lower side. By configuring the inner surface of the container to be inclined downward, the strength in the direction of gravity can be increased. That is, although the container 10 has a folding structure, it may have an inclined sidewall to increase its strength in the direction of gravity and may be able to stand by itself without a separate support member.

In some embodiments, the folded state of the second folding part 220 folded along the folding line may be fixed through the adhesive member 400. In addition, the fourth folding part 240 folded along the folding line may be fixed in a folded state through the adhesive member 400. On the other hand, the first folding part 210 and the third folding part 230 folded along the folding line are fixed by the second folding part 220 and the fourth folding part 240 without a separate adhesive member. You can keep it fixed. That is, when the folding part 200 is folded, the second folding part 220 and the fourth folding part 240 overlap the first folding part 210 and the third folding part 230 so as to be positioned. Therefore, only by fixing the second folding part 220 and the fourth folding part 240, the first folding part 210 and the third folding part 230 positioned on the upper side can be maintained in a fixed state. In the future, until the user unfolds the folding structure of the container 10, the adhesive member 400 may maintain the folded structure.

In this embodiment, the adhesive member 400 is illustrated in the form of an adhesive tape, but the present invention is not limited thereto, and the adhesive member 400 may be an adhesive or the like.

Hereinafter, the folding structure of the container 10 according to the present embodiment will be described in detail with reference to FIG. 4. 4A is a plan view showing a deployment area for manufacturing the container of FIG. 1. 4B is a view showing the first folding part 210a of FIG. 4A. 4C is a view showing the second folding portion 220a of FIG. 4A. 4D is a view showing the third folding part 230a of FIG. 4A. 4E is a view showing the fourth folding part 240a of FIG. 4A. Hereinafter, in the drawing of the development sheet, a dashed-dotted line indicates a fold line configured to be convexly folded with respect to one side, and a dashed-dotted line indicates a fold line configured to be concavely folded based on one side.

With further reference to FIG. 4, the deployment paper 10a for manufacturing a disposable container includes a side wall portion 110a, a first folding part 210a, a second folding part 220a, and a third folding part ( 230a) and the fourth folding portion 240a, and may further include a bottom portion 250a.

The sidewall portion 110a includes an upper side of the first folding part 210a, an upper side of the second folding part 220a, an upper side of the third folding part 230a, and an upper side of the fourth folding part 240a. You can touch and share any side. In an exemplary embodiment, the upper edge of the sidewall portion 110a may form a bow shape. That is, the edge may have a curved shape. The curved edge may be partially rolled outward to form an extended portion 115 of the container body portion 110. As a non-limiting example, the sidewall portion 110a may not substantially have a folding structure.

The first folding part 210a, the second folding part 220a, the third folding part 230a, and the fourth folding part 240a each have a folding structure, and they together form the folding part 200 of FIG. Can be formed. Each of the first folding part 210a, the second folding part 220a, the third folding part 230a, and the fourth folding part 240a may have a substantially rectangular shape, for example, a trapezoidal shape. Specifically, each of the first folding part 210a, the second folding part 220a, the third folding part 230a, and the fourth folding part 240a may have a trapezoidal shape having a weak upper side. This may be because, as described above, the upper end of the container body portion 110 of the container 10 does not have an angle, while the shape is deformed to have an angle toward the lower end. In the present invention, the upper side of the first folding part 210a, the second folding part 220a, the third folding part 230a, and the fourth folding part 240a have a weak bow shape when they are trapezoidal. It will be apparent to those of ordinary skill in the art that it belongs to the equivalent variation of. Hereinafter, for convenience of explanation, the shape of the first folding part 210a, the second folding part 220a, the third folding part 230a, and the fourth folding part 240a is described as an example. The present invention is not limited thereto.

For example, the first folding part 210a, the second folding part 220a, the third folding part 230a, and the fourth folding part 240a have an upper side (sect side) and a lower side, respectively, and are substantially parallel. , The left side and the right side may have a trapezoidal shape having an inclination. For a specific example, the first folding part 210a, the second folding part 220a, the third folding part 230a, and the fourth folding part 240a have a square trapezoidal shape with the same inclination of the left and right sides, respectively. I can.

The right side of the first folding part 210a may be adjacent to and abutted with the left side of the second folding part 220a. That is, the first folding part 210a and the second folding part 220a may share any side. Further, the right side of the second folding portion 220a may be adjacent to and abutted with the left side of the third folding portion 230a. That is, the second folding part 220a and the third folding part 230a may share any side. In addition, the right side of the third folding part 230a may be adjacent to and abutted with the left side of the fourth folding part 240a. That is, the third folding part 230a and the fourth folding part 240a may share any side.

Each of the first folding part 210a, the second folding part 220a, the third folding part 230a, and the fourth folding part 240a may have a folding line in a horizontal direction. Specifically, the first folding portion 210a has a first horizontal folding line 511 extending in a direction parallel to an upper side (or lower side) thereof, and the second folding portion 220a has an upper side (or A second horizontal fold line 521 extending in a direction parallel to the lower side), and the third fold portion 230a is a third horizontal fold line extending in a direction parallel to the upper side (or lower side) thereof ( With 531), the fourth folding part 240a may have a fourth horizontal folding line 541 extending in a direction parallel to the upper side (or lower side) thereof.

The first horizontal fold line 511 and the second horizontal fold line 521 abut each other, the second horizontal fold line 521 and the third horizontal fold line 531 abut each other, and the third horizontal fold line ( The 531 and the fourth horizontal fold line 541 may contact each other. In an exemplary embodiment, the first horizontal fold line 511 and the third horizontal fold line 531 are processed to be convexly folded on one surface, and the second horizontal fold line 521 and the fourth horizontal fold line ( The 541 may be processed to be concavely folded on one side. The processing may include a stamping process such as paper plywood, etc., but the present invention is not limited thereto, and the folding line may be configured to be convex or concave folded.

In addition, the first folding portion 210a passes through the midpoint of the first horizontal folding line 511, and is processed to be convexly folded with respect to the one surface of the'X'-shaped'X'-shaped folding lines 512 and 513. ) May be further provided. In addition, the third folding part 230a passes through the midpoint of the third horizontal folding line 531, similar to the first folding part 210a, and has a'X' shape processed to be convexly folded with respect to the one surface. 'X'-shaped folding lines 532 and 533 may be further provided. Accordingly, the first folding part 210a and the third folding part 230a may have both a folding line configured to be convexly folded and a folding line configured to be concave folded. As a non-limiting example, the second folding part 220a and the fourth folding part 240a may not have an additional folding structure other than the horizontal folding part.

In some embodiments, the minimum distance from the upper side of the first fold portion 210a to the first horizontal fold line 511 is the minimum distance from the lower side of the first fold portion 210a to the first horizontal fold line 511 May be greater than the distance. For example, the minimum distance to the upper side is about 1.3 times, or about 1.4 times, or about 1.5 times, or about 1.6 times, or about 1.7 times, or about 1.8 times, or about 1.9 times the minimum distance to the lower side. Or it may be about 2.0 times. If the minimum distance to the upper side is less than 1.3 times the minimum distance to the lower side, the vertical length of the first folding part 210a cannot be sufficiently secured in order to form a stable folding structure. Therefore, the difference in volume of the accommodation space in the folded state and the unfolded state may not be large. On the other hand, when the minimum distance to the upper side is more than twice the minimum distance to the lower side, the container 10 may not have a structure that is robust enough to maintain a standing state by itself in the unfolded state.

Similarly, the second horizontal fold line 521 of the second fold portion 220a, the third horizontal fold line 531 of the third fold portion 230a, and the fourth horizontal fold line of the fourth fold portion 240a ( 541) may be positioned so that the minimum distance to the upper side thereof is greater than the minimum distance to the lower side.

When manufacturing the container 10 by assembling the deployment paper 10a according to the present embodiment, the container may be configured such that the volume of the receiving space therein is variable. In addition, the first horizontal fold line 511, the second horizontal fold line 521, the third horizontal fold line 531, and the fourth horizontal fold line 541 may be positioned at the same level. In addition, the fourth horizontal fold line 541 and the first horizontal fold line 511 may be configured to abut.

The bottom portion 250a may be disposed in contact with any one of the first folding portion 210a, the second folding portion 220a, the third folding portion 230a, and the fourth folding portion 240a. 4 illustrates a case in which the bottom portion 250a is disposed in contact with the lower side of the third folding portion 230a, but the present invention is not limited thereto. In another embodiment, the bottom portion 250a is disposed in contact with the lower side of the first folding portion 210a, disposed in contact with the lower side of the second folding portion 220a, or the fourth folding portion 240a It may be arranged in contact with the lower side.

In an exemplary embodiment, the side wall portion 110a, the first folding portion 210a, the second folding portion 220a, the third folding portion 230a, and the fourth folding portion 240a are formed integrally, but the sidewall The thickness of the portion 110a (that is, the thickness of the deployment paper 10a) is that of the first folding part 210a, the second folding part 220a, the third folding part 230a, and the fourth folding part 240a. It may be larger than the thickness (that is, the thickness of the deployment paper 10a). For example, the sidewall portion 110a, the first folding portion 210a, the second folding portion 220a, the third folding portion 230a, and the fourth folding portion 240a are all formed of a plurality of layers. It is manufactured by a plywood process, and the sidewall part 110a, the first folding part 210a, the second folding part 220a, the third folding part 230a, and the fourth folding part 240a share at least some layers. However, the sidewall part 110a is processed by a plywood process to have more layers than the first folding part 210a, the second folding part 220a, the third folding part 230a, and the fourth folding part 240a. May be in the state.

By forming different thicknesses of the side wall portion 110a forming the container body portion 110 of the container 10 and the first folding portion 210a to the fourth folding portion 240a forming the folding portion 200 While improving the structural stability and strength of the container 10, it is possible to facilitate the formation of a folding structure.

When assembling the deployment paper 10a for manufacturing the disposable container according to the present embodiment according to the folding structure, the container 10 according to the embodiment such as FIG. 1 may be manufactured. The container 10 and the deployment paper 10a according to this embodiment have an efficient folding structure and can maximize the degree of variability in size.

The first sub sidewall 210c may have a trapezoidal shape in which the length of the upper side is larger than the length of the lower side. The inner surface of the first sub sidewall 210c may form a substantially flat surface.

The first sub-sidewall 210c having a quadrangular shape may include a 1-1 fold line 512 and a 1-2 fold line 513 crossing the first sub side wall 210c in a diagonal direction. The first-first fold line 512 and the first-second fold line 513 may correspond to the'X'-shaped fold lines 512 and 513 described above. The first-first fold line 512 and the first-second fold line 513 may mean a fold line or a trace of a fold line configured to be concavely folded with respect to an outer surface, respectively. That is, when the first sub-sidewall 210c is made of a non-flexible material with a folding structure, the trace of the fold line may be visually recognized while the folding structure of the first sub-sidewall 210c is fully unfolded.

In addition, the first sub-sidewall 210c may include a 1-3 fold line 511 that crosses the first sub-sidewall 210c in a horizontal direction. The 1-3 fold lines 511 may correspond to the first horizontal fold lines 511 described above. The 1-3 fold line 511 may mean a fold line configured to be convexly folded with respect to the outer surface or a trace of the fold line. The 1-3 th fold line 511 may pass through a point where the 1-1 fold line 512 and the 1-2 fold line 513 intersect.

The second fold line 521 is located at the same level as the 1-3 fold line 511 and may contact the 1-3 fold line 511.

The third sub-sidewall may face the first sub-sidewall 210c, and the fourth sub-sidewall may face the second sub-sidewall 220c. The third sub-sidewall and the fourth sub-sidewall may have the same folding structure as the first sub-sidewall 210c and the second sub-sidewall 220c, respectively.

Specifically, the third sub-sidewall may have a trapezoidal shape in which the length of the upper side is larger than the length of the lower side. The inner surface of the third sub sidewall may form a substantially flat surface. The quadrangular third sub-sidewall may have a 3-1 fold line and a 3-2 fold line crossing the third sub sidewall in a diagonal direction. The 3-1 fold line and the 3-2 fold line may correspond to the'X'-shaped fold lines 532 and 533 described above. The 3-1 fold line and the 3-2 fold line may mean a fold line or traces of fold lines configured to be concavely folded with respect to the outer surface, respectively.

Further, the third sub-sidewall may have a 3-3 fold line crossing the third sub-sidewall in a horizontal direction. The 3-3 fold line may correspond to the third horizontal fold line 531 described above. The 3-3 fold line may mean a fold line configured to be convexly folded with respect to the outer surface or a trace of the fold line. The 3-3 fold line may pass through a point where the 3-1 fold line and the 3-2 fold line intersect. In addition, the 3-3 fold line may abut the second fold line 521.

The quadrangular fourth sub-sidewall may have a fourth fold line crossing the fourth sub-sidewall in a horizontal direction. The fourth fold line may correspond to the fourth horizontal fold line 541 described above.

The fourth fold line is positioned at the same level as the 3-3 fold line and the 1-3 fold line 511 and may contact the 3-1 fold line and the 1-3 fold line 511.

In addition, the folding part 200 may further include a bottom surface 250. The bottom surface 250 may be a portion that forms the bottom of the container 10 when used in the unfolded state of the container 10. The bottom surface 250 may correspond to the bottom portion 250 described above.

The bottom surface 250 may be substantially square in plan view. The bottom surface 250 is in contact with the lower side of the first sub-sidewall 210c, the lower side of the second sub-sidewall 220c, the lower side of the third sub-sidewall, and the lower side of the fourth sub-sidewall to share a side. I can.

The container 10 according to the present embodiment has a folding structure, but some of the folding lines positioned at the same level are convexly folded with respect to the outer surface (ie, the 1-3 folding lines 511 and the 3- 3 fold line), and the other part is configured to be concavely folded (ie, the second fold line 521 and the fourth fold line) based on the outer surface, so that the strength in the direction of gravity can be increased.

If all folding lines located at the same level are configured to be folded in the same direction, they are very vulnerable to pressure in the direction of gravity, and the container can stand up by itself when the contents, especially hot hot water or food are accommodated inside. Failure to maintain it can cause major problems.

In the folding part 200 of the container 10 according to the present embodiment, some of the folding lines located at the same level have a convex folding structure based on the outer surface, and others have a concave folding structure. Can be solved.

In addition, the first sub-sidewall 210c and the third sub-sidewall are each of the 1-1 fold lines 512, 1-2 fold lines 513, 3-1 fold lines and It is possible to further increase the strength of the container 10 in the vertical direction by further providing a 3-2 fold line. The 1-1 fold line 512, the 1-2 fold line 513, the 3-1 fold line, and the 3-2 fold line extending in the diagonal direction are compared to the fold line extending in the vertical or horizontal direction. It can improve the support in the direction of gravity. In addition, for example, the first sub-sidewall 210c is convexly folded along with the 1-1 fold line 512 and the 1-2 fold line 513 concavely folded. 511), but it is possible to increase the support strength of the first sub sidewall 210c itself by configuring the three fold lines to intersect at one point. Similarly, the third sub-side wall has a 3-1 fold line that is concavely folded and a 3-3 fold line that is convexly folded together with the 3-2 fold line, but the three fold lines are configured to intersect at one point. Thus, the support strength of the third sub sidewall itself can be increased.

In an exemplary embodiment, a folding portion 200 including a container body portion 110 forming a main sidewall, a first sub-sidewall 210c, a second sub-sidewall 220c, a third sub-sidewall, and a fourth sub-sidewall. ) Is formed integrally and configured to be assembled from a single deployment paper, and the thickness of the container body portion 110 (the sidewall portion 110a on the expanded view) may be greater than the thickness of the folding portion 200. For example, the container body part 110 and the folding part 200 are each manufactured by a plywood process so as to consist of a plurality of layers, and the container body part 110 and the folding part 200 share at least some of the layers. , The container body part 110 may be manufactured by a plywood process to have more layers than the folding part 200.

Since the folding part 200 has a folding structure so that it can be folded multiple times, it may be difficult to completely fold it when the thickness is too thick. On the other hand, since the container body part 110 does not have a folding structure, it is formed to have a sufficient thickness to minimize heat transfer even when hot contents such as hot water are accommodated therein, and a more robust structure can be formed.

The container 10 according to the present embodiment has an efficient folding structure and can maximize the difference in volume of the accommodation space in a fully folded state and an unfolded state. Through this, for example, in the case of storing, distributing, or discarding the container 10, the first sub-sidewall 210c, the second sub-sidewall 220c, the third sub-sidewall, and the fourth sub-sidewall are folded. By minimizing the volume along the lines, storage, etc. can be facilitated, and furthermore, the storage volume can be minimized even when stored in a warehouse or bag. For example, the volume of the interior accommodation space after the folding structure is unfolded is about 1.5 times or more, or about 1.6 times or more, or about 1.7 times or more, or about 1.8 times the volume of the interior accommodation space in the folded state. Or more, or about 1.9 times or more, or about 2.0 times or more.

In addition, when using the container 10, a sufficient internal space can be provided by unfolding and using folding lines provided by the first sub-sidewall 210c, the second sub-sidewall 220c, the third sub-sidewall, and the fourth sub-sidewall. In addition, a sufficient amount of hot water, etc., can be introduced to enable cooking. In addition, the folding lines can reinforce the support strength of the container 10 in the gravitational direction, and the bottom surface of the bottom surface 250 or four sides abut against a horizontal surface, so that the standing state can be maintained without a separate reinforcing member.

In addition, the container body portion 110 forming the main sidewall of the container 10 and the folding portion 200 forming the sub sidewall in the unfolded state are all made of paper or synthetic resin, but are integrally formed, Since it is not made of the material of, the manufacturing cost can be reduced and the manufacturing process can be simplified. Moreover, when formed of paper or the like without including a silver foil material, it is possible to use a microwave oven, etc., and thus, there is an advantage of having more various uses.

On the other hand, in the case of conventional cup noodles, there is a limit in that the cup noodles container must have an excessively large volume compared to the dried contents in order to sufficiently heat cooking by pouring hot water. In the case of cereal products, the packaged cereal in order to bring in a sufficient amount of milk had too much volume in the container compared to the amount of the contents. In the case of the container 10 according to the present invention, when the first ramen or cereal is accommodated and stored or sold, the volume is kept to a minimum as shown in FIG. 1, and only when hot water or milk is poured into FIG. It can be used by increasing the volume together.

In addition, in the case of instant-cooked foods other than cup noodles, such as semi-cooked retort foods packaged in one bowl, stew foods such as bagged stew, and camping foods, they are provided in a packaged state without a separate container to minimize the volume. And, when cooking is completed using a bath or the like or according to the present invention, this problem can also be solved.

Hereinafter, other embodiments of the present invention will be described. However, a redundant description of the same configuration as the container and deployment paper according to the above-described embodiment will be omitted, and this will be clearly understood by those skilled in the art from the accompanying drawings.

In addition, contents (not shown) may be accommodated in the inner space formed by the container body part 600 and the folding part 700.

The container body 600 and the folding part 700 may be made of paper or synthetic resin, respectively. In addition, the container body part 600 and the folding part 700 may be processed to have non-flexible characteristics. For example, it may be processed to have sufficient thickness, strength, and rigidity through a plywood process or the like.

The container body part 600 may form a side wall in which the container 20 can accommodate the contents of the container 20 in an initial state.
