Description

  The present invention relates to an easy-open packaging body, and more particularly to an easy-open packaging body that can be used as a horizontal container and a vertical container.

  In a soft package that contains moisture-containing contents, such as wet tissue, it is convenient to carry, easy to remove, and resealed to prevent drying when the remaining wet tissue is reused Flexible packaging that can be used has been studied. As such a soft package, for example, in Patent Document 1 below, a slit is formed in the bag body to form an opening, and a lid member that can be peeled off with an adhesive is provided thereon. An enclosing bag of a cosmetic fiber material or the like is described, and a flexible film packaging body having an opening and capable of resealing the opening is disclosed.

  In addition, combining the above-mentioned flexible package and a rigid container that accommodates wet tissue is also being studied. For example, in Patent Document 2 below, the wet tissue separated one by one is stacked in a planar shape. A package comprising a film-like soft packaging body for accommodating the package and a rigid container for laterally housing the soft packaging body so that the wet tissue plane is horizontal, the rigid container being a so-called pop-up type A package body is disclosed which has a take-out port on the top surface of the container so that the wet tissue pieces can be drawn out and taken out continuously. Since this rigid container is provided with a wet tissue outlet at the center of the top surface of the container, the opening of the flexible package is also provided at the center.

On the other hand, as a rigid container for storing wet tissue, in Patent Document 3 below, wet sheet pieces separated one by one are folded and stacked, and the wet sheet pieces are directly stored so that the wet sheet pieces are vertical. A rigid container having a structure in which a sheet is drawn out from a take-out port arranged on the top surface of the container is disclosed.

  As in Patent Document 2, when a soft packaging body that accommodates wet tissue and a rigid outer container that accommodates the wet tissue are combined, the position of the opening of the soft packaging body matches the opening of each rigid container. Soft packaging must be used. For example, in the case of a normal horizontal installation type, an annular opening such as an ellipse or a square may be formed at a position corresponding to the substantially central portion of the wet tissue plane of the flexible package. However, in the case of the vertical installation type, when the opening of the outer container is formed above the opening, the opening of the flexible packaging body is accordingly in accordance with the upper end of the packaging body from the substantially central portion. It is preferable that it is formed from the viewpoint of wet tissue take-out property.

  Thus, for example, even if the purpose of use is similar and the contents are exactly the same sheet (chemical solution, non-woven fabric, dimensions), depending on how the outer container is placed horizontally or vertically, It is very inconvenient to purchase a special product for soft packaging for refilling that matches the shape.

  However, in the conventional soft packaging bodies such as the above-mentioned Patent Documents 1 to 3, the placement method is determined to be horizontal or vertical, so that the refill type wet tissue soft can be used for both at the same time. Packaging has not been studied.

  This invention is made | formed in view of the above subjects, The objective is to provide the easy-open packaging body which can be used combining both a horizontal container and a vertical container from which the opening part position differs. is there.

  More specifically, this invention provides the easy-open packaging body which consists of the following structures.

  (1) A packaging body made of a film-like soft packaging material, wherein the packaging body has a packaging body having an opening area for taking out contents, and a lid that covers the opening area and is detachably adhered The lid material can be peeled from both sides across the opening region, and the opening region is formed by providing an annular first lead wire in the flexible packaging material, Two pieces extending toward one peeling end portion starting from two points located substantially symmetrically with respect to the central axis of the opening region along the peeling direction of the lid material on the annular first margin line The easy-open packaging body provided with the second score line.

  According to the easy-open packaging body of the present invention, when the cover material is peeled from the other peeled end portion of the cover material, the soft packaging material is continuously formed by the second cut line continuously from the annular first cut line. Is peeled off, and a continuous opening from the first lead-in line to the end of the package is formed. Thereby, in this case, a large opening from the substantially central portion to the end of the soft package is formed, which is particularly suitable as a soft package to be accommodated in a vertical exterior container.

  On the other hand, when the lid member is peeled from one peeled end portion on the opposite side, the second cut line is formed in the direction opposite to the peel direction, so that the flexible packaging material is not peeled off. For this reason, only the opening part along the annular first insertion line is formed as it is. In this case, since the annular opening is formed only in the substantially central portion of the soft package, it is particularly suitable as a soft package to be housed in a horizontal outer container.

  Thus, according to the present invention, although it is a single type of flexible package, depending on the direction in which the lid material is rolled, it can be formed using different openings corresponding to both the vertical container and the horizontal container, It is particularly suitable as a general-purpose refill wet tissue package.

  The term “extends toward one peeling end” in the present invention means that when peeled from the other peeling end, it is continuous from the annular first cut line and is softly wrapped by the second cut line. It means the direction in which the material is peeled off, and may be a straight line or a curved line, or a wavy line or a rectangular line.

  (2) When the lid member is peeled from the other peeling end portion of the lid member, a continuous opening portion is formed by the second cut line from the opening region to the end portion of the packaging body. The easy-open packaging body according to (1), wherein tearing guiding means for guiding tearing of the soft packaging material is formed on the soft packaging material.

  According to this aspect, since the tearing guiding means is formed in the soft packaging material, when the lid member is peeled off from the other peeling end, a large opening can be easily made from the first fold line to the end of the packaging body. The part can be formed.

  (3) The end portion including the end point of the second cut line is an angle formed with a line parallel to the peeling direction, and the angle on the one peeling end side is less than 90 °. The easy-open packaging body according to (1) or (2).

  According to this aspect, since the end point of the second score line is formed in the peeling direction, the direction of tearing the film is guided. For this reason, a film is torn in a fixed direction, and an opening part is formed stably. In addition, the shape of the “second cut line” in this aspect is not particularly limited, and may be formed by combining one or two or more straight lines, a curve and a straight line, but the portion including the end point is a straight line. Is formed. The straight line portion including the end point is “the end portion including the end point of the second cut line”, and such end portion may be at least 1 mm from the end point, and preferably 5 mm or more.

  (4) On the surface of the soft packaging material covered with the lid material, a fragile portion formed by a fragile processing process is formed on the one peeling end side as viewed from the second cut line or the opening region. The easy-open packaging body according to any one of (1) to (3).

  According to this aspect, the rigidity of the film can be substantially reduced by the weakened portion provided on the surface of the flexible packaging material. For this reason, when the lid member is peeled off, the film easily follows and adheres to the lid member side, so that it can be surely separated along the tear guiding means, and the opening can be reliably provided.

  The “fragile portion” formed by the fragile processing may be, for example, a continuous line or a linear cut line formed by perforation processing or laser processing. Further, it is not limited to the score line, and is formed by, for example, an embossing process in which a diamond piece adheres to the surface, and is a fine scratch-like unevenness formed on a part or all of the film surface of the opening region. Also good.

  (5) The easy-open packaging body according to any one of (1) to (4), wherein the peeled end portion of the lid member has weaker adhesive strength than other portions or does not have adhesiveness. .

  According to this aspect, the peeling end can be easily grasped, and the lid material can be easily peeled off.

  (6) The easy-open packaging body according to any one of (1) to (5), wherein the packaging body is a sealed packaging body, and the content is a wet tissue.

  According to this aspect, the wet tissue for refilling is normally accommodated in the pillow package, and it is necessary to take out the wet tissue easily from there, and a particularly large opening is required. In this regard, with the easy-open packaging body of the present invention, a large opening can be formed, and the wet tissue can be easily taken out regardless of whether the exterior container is placed vertically or horizontally. Moreover, since it is a hermetic package, the contents such as wet tissue can be prevented from drying.

  According to the present invention, since openings having different shapes can be formed depending on the direction in which the cover material is peeled off, the shape and position of the opening of the exterior container can be used together with different containers. An openable package can be provided.

  Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings. In the following description of the embodiments, the same constituent elements are denoted by the same reference numerals, and the description thereof is omitted or simplified.

<Overall configuration of easy-open packaging>
1 and 2 are views showing an example of an embodiment of an easy-open packaging body according to the present invention, FIG. 1 is a perspective view showing an outline of the easy-open packaging body, and FIG. It is an enlarged view.

  As shown in FIG. 1, the package 100 is a pillow package composed of a film 110 made of a flexible packaging material. In the state where the package 100 is placed horizontally, the lid member 200 is adhered to the upper surface side of the film 110. Reference numerals 131 and 132 denote upper and lower horizontal seal portions, respectively, and a vertical seal (back seal) portion (not shown) is provided at the center on the back side.

  As shown in FIG. 2, an annular first cut line 210 and a second cut line 220 are formed in a portion of the film 110 covered by the lid member 200. The annular cut line 210 provides an opening area 150 on the inner side. The lid member 200 has peeling end portions 230 and 231 in both directions, and is adhered to the film 110. In order to make it easy to peel off the label from both directions, it is preferable that the peeling end portions 230 and 231 have a lower adhesive strength than other portions or have no adhesiveness. Here, “adhesion” refers to a state where re-peeling and resealing are possible.

  On the extension of both end points of the second cut line 220 on the upper surface of the film 110, two parallel tear guiding means 160 extending from there to the lateral seal portion 132 are provided. In this embodiment, the tearing induction means 160 is described as a virtual line. Actually, the stretched direction of the stretched film constituting the film 110 coincides with the direction of the virtual line. Is the tearing induction means 160.

<Film>
The film 110 is not limited to a specific material, but is preferably a material having moisture resistance for preventing the inner wet tissue from being dried by fusing the film to obtain a bag-like shape by heating. Moreover, the material can use the raw material which has adhesiveness and airtightness by itself, and can also use the raw material which bonded several types of films each having a different characteristic.

  In addition, when a base film is used, such as a uniaxially stretched PET film, which has improved unidirectional tearability, a linear and stable opening is formed when the opening is formed while tearing the film from the slit. This is preferable.

<First margin and opening area>
The all-inclusive line 210 may be provided so as to generate the annular opening region 150. In FIG. 2, although it has the shape of an elliptical first-line, it may be square or round and is not particularly limited. It is important that the end of the opening formed after the cover member 200 is peeled off is provided with a resistance that affects the separation of the overlap between the sheet housed therein and the rubbing sheet. . In addition, the size of the opening region 150 serving as the take-out port can be appropriately selected according to the size of the package 100 and the size and shape of the contents to be taken out.

  The first lead-in wire 210 may be in a state of being completely opened by punching out the film, or a part or a plurality of parts connected to the film 110 of the packaging body so as to be naturally cut when the label is peeled off, so-called perforation. You may be in a state. Moreover, it may not be completely punched in the thickness direction of the film as referred to as a half cut, but may be in a state where it is not cut to the lowest layer of the film. In any case, it is sufficient that the opening of the package corresponding to the opening of the horizontal container is formed when the lid 200 is peeled off.

<Second cut line>
The second cut line 220 is two points on the annular first cut line 210, and the opening region starts from two points that are substantially symmetrical with respect to the central axis of the opening region along the peeling direction of the lid member. Are formed symmetrically with respect to the central axis. In this embodiment, each second cut line 220 has an L-shape extending in a direction perpendicular to the central axis of the opening region and then parallel to the peeling direction toward the peeling end 230. .

  The second incision line 220 only needs to extend from the two points located substantially symmetrically to the central axis of the opening region along the peeling direction of the lid material to the one peeling end side, The shape is not particularly limited. As another example, as shown in FIG. 3, it may be a second cut line 221 provided substantially parallel to the peeling direction, and as shown in FIG. The second cut line 222 may be provided obliquely with an acute angle of less than. In addition, as an example in which the opening region has a quadrangular shape, as shown in FIG. 5, the second cut line 223 is provided starting from an arbitrary point on the first cut line parallel to the peeling direction. Alternatively, as shown in FIG. 6, the second cut line 224 may be provided starting from an arbitrary point on the first cut line perpendicular to the peeling direction.

  Moreover, as shown in FIG. 7, the V-shaped weak part 240 may be provided in the one peeling end part side of the 2nd cut line 220. As shown in FIG. The fragile portion 240 can reduce the rigidity of the film 110. Thereby, since the film 110 is easily bent, the film 110 is easily cut and raised from the second incision line 220, and the adhesion to the lid member 200 is ensured.

  Further, as shown in FIG. 8, a weakened portion 241 that is in contact with the first cut line and formed perpendicular to the peel direction may be provided on one peel end portion side of the second cut line 221. The weak part should just be formed so that the film 110 may bend easily, and the shape, length, and number can be set suitably. For example, the fragile portion may have a zigzag shape, a wave shape, an R shape, or a combination of different shapes. Moreover, only one may be sufficient and perforation may be sufficient instead of a continuous line.

  Further, the cut line may be formed so as to penetrate the film 110, and may be in a so-called half cut state. However, from the viewpoint of making the film 110 easier to bend by reducing the rigidity of the film. It is preferable to be formed so as to penetrate. The half cut can be formed by a known method such as laser light irradiation or mechanical cutting blade processing.

  On the other hand, as shown in FIGS. 9 and 10, when the angle formed by the second cut line and the peeling direction is 90 ° or more from the peeling end 230, the lid 200 is peeled from the peeling end 231 side. Since the direction of tearing is not guided when the film 110 is torn from the second score line, it is not preferable because it is caught at the end point of the slit, or the direction of tearing or the size of the opening formed is unstable. .

  The second score line 220 is preferably completely punched out of the film in order to stabilize the direction of tearing the film as much as possible. In the case of perforations, when the portion connected to the film 110 is cut, the breaking direction is disturbed, and there is a possibility of tearing in an undesired direction. In the case of half-cut, since a part of the lowermost film that is not cut remains, the breaking direction is similarly disturbed, it is torn in an undesired direction, or the upper film and the lower film called delamination are broken It is not preferable because the opening may not be stably formed after peeling.

<Tearing induction means>
In this embodiment, the tearing induction means 160 is described as a virtual line. Actually, the stretched direction of the stretched film constituting the film 110 coincides with the direction of the virtual line. Is the tearing induction means 160. Specifically, for example, the base layer of the film 110 may be a stretched film, preferably a highly oriented uniaxial or biaxially stretched film. A stretched film is more preferable. A conventionally well-known commercial item can be used for these stretched films.

  The tear guiding means 160 is not limited to the above-described stretching orientation, and for example, a cut line may be formed on the film 110. In this case, the cut line may be formed so as to penetrate the film 110 and may be in a so-called half-cut state. However, in order to maintain the sealing performance of the entire package, it is in the half-cut state. Preferably there is. The half cut can be formed only on the base material layer, for example, by a known method such as laser light irradiation or mechanical cutting blade processing.

<Cover material>
The lid member 200 is formed of a flexible film or sheet having flexibility, and a pressure-sensitive adhesive that forms an adhesive layer is, for example, a polychlorinated material containing an acrylic glue or a plasticizer. A vinyl composition or a kraftmer mainly composed of a kraft copolymer in which a vinyl chloride monomer is kraft polymerized to an ethylene-vinyl acetate copolymer can be exemplified, but is not limited to a specific one.

  The shape of the lid member 200 is an elliptical shape in FIG. 2, but the shape is not limited. The shape may be rectangular or circular as long as the first cut line 210, the second cut line 220, and the like can be reliably covered.

  In addition, it is preferable that the peeling edge parts 230 and 231 of the lid | cover material 200 have weak adhesive strength compared with other parts, or do not have adhesiveness.

<Action>
Next, the effect | action of this package 100 is demonstrated using FIGS. 11-14. 11 is a perspective view showing a state in the middle of peeling the lid member 200 from the peeling end 231 in FIG. 1, and FIG. 12 is a perspective view showing a state after peeling. 13 is a perspective view showing a state in the middle of peeling the lid member 200 from the peeling end 230 in FIG. 1, and FIG. 14 is a perspective view showing a state after peeling.

  First, in the package 100, the lid member 200 is peeled from the peeling end 231 side of the lid member 200. Then, the opening area 150 is adhered by the adhesive on the back surface side of the lid member 200, and the opening area 150 of the film 110 is separated along the first insertion line 210 and lifted. Further, when the lid member 200 is peeled off, the tear line is transferred to the second cut line 220, and the film 110 starts to tear along the tear guide means 160, which is a virtual line, and tears to the lateral seal portion 132 to form an opening. Then, the openings 110a and 110b are integrally formed. This integral opening can be suitably used when the outer container is a vertical container.

  15 and 16 show an example of a wet tissue package 400 in which the package 100 as described above is combined with a vertical outer container 300. As shown in FIG. 15, this wet tissue package 400 is mainly composed of a rigid outer container 300 and the above-described package 100 containing a plurality of wet tissue pieces housed in the outer container 300. It is configured.

  As shown in FIG. 16, the package 100 is sealed by a bottom lid 320 after a plurality of wet tissue pieces are inserted and arranged from the bottom of the outer container 300 in an upright state, that is, in a so-called vertical state. Thus, the package 100 in which the openings 110a and 110b are integrally formed as described above can be suitably used as a refillable wet tissue package used for a vertical outer container.

  The exterior container 300 is mainly composed of a main body part 310 that accommodates the package 100 and a bottom lid 320 that can be fitted to the bottom part of the main body part 310 so as to be airtight, and the main body part 310 has a hollow, substantially rectangular parallelepiped shape. I am doing. A second opening region 330 for taking out the wet tissue piece is formed from the front upper portion of the main body portion 310 to the upper surface. The second opening area 330 is provided with an openable / closable lid 340 so as to cover the second opening area 330 in an airtight state. The lid 340 has a hinge portion as a fulcrum. It can be moved up and down.

  The second opening region 330 is formed above a position that is ½ of the height of the outer container 300. As a result, the wet tissue is taken upward, and friction between the lower end portion of the second opening region and the wet tissue piece occurs. Therefore, the wet tissue pieces can be surely separated without forming special nails and slits, and the wet tissue can be taken out one by one.

  On the other hand, when the lid member 200 is peeled from the peeling end portion 230 side of the lid member 200, the opening region 150 is adhered by the adhesive on the back surface side of the lid member 200, and the opening region 150 of the film 110 is completely removed. It is cut along the tangent line 210 and lifted. However, even if the lid member 200 is peeled off, the second cut line remains as it is without peeling off the film. Accordingly, an opening 110a as shown in FIG. 14 in which only the shape along the first insertion line 210 is opened is formed. In this case, since the open end of the package remains as it is, it does not impair the function of taking out even when stored in a horizontal container.

  INDUSTRIAL APPLICABILITY The present invention can be suitably used as an easy-open packaging body that can be used as a container having a different opening position, for example, a wet tissue packaging body for refilling.
