Description

individual packing box

technical field

The present invention relates to an individual packaging box (SINGLE-ARTICLEPACKAGING BOX) used as commodity packaging, and particularly relates to an individual packaging box that realizes easy unsealing.

Background technique

As product packaging, individual packaging boxes based on thick paper, cardboard, etc. are widely used. There are various styles of individual packaging boxes, and the individual packaging boxes that are assembled into a box shape after punching out the unfolded graphics of the box from paper, and make at least one side a door that can be opened and closed freely are one of the general individual packaging boxes.

4A and 4B show an example of the above-mentioned individual packing box. The structure of the individual packaging box 1 shown in the figure is as follows: one end surface in the longitudinal direction is formed as a door 2 that can be opened and closed in a hinged manner, as shown in FIG. 3. As shown in FIG. 4B , insert the flap part 3 into the inside of the individual packaging box 1 to close the door 2 . In addition, there is also an individual packing box in which a linear slit 4 is formed at both ends of the fold line of the door 2 and the flap part 3. At this time, when the door 2 is closed, the slit 4 of the door 2 and the The flaps 5 at the edges of the sides of the box (upper and lower sides in the figure) are snapped together so that the door 2 cannot be opened unintentionally. When opening the door 2, put your finger on the flap 3 of the door 2 to pull the door open, but your fingers are not easily inserted between the flap 3 of the door 2 and the side of the individual packing box 1, and there are many individual packages Box As shown in FIG. 5 , a notch 6 is formed at the edge of the door side of the individual packing box 1 to make it easy to put fingers on the flap 3 of the door 2 .

In addition, there is a "container for packaging" disclosed in JP-A-52-45468 as a package whose door can be opened more easily. The structure of this "packaging container" is as follows: a semicircular or door-shaped slit is processed from the middle part of the fold line of the door and the flap part to the side of the flap part, and when the flap part is bent, it is surrounded by the slit The part of the flap does not bend, but becomes a louver (cut up こし) on the same plane as the door, and the louver standing up from the flap part becomes a finger hook when opening the door, making it easy to open the door.

The conventional individual packaging boxes shown in Figures 4A and 4B have the disadvantage that fingers are not easily inserted between the flaps and the side of the box when the door is opened, and the individual with a notch formed on the edge of the box as shown in Figure 5 Although the packing box is easy to put fingers on the flap part, any one of Fig. 4A, Fig. 4B and Fig. 5 is that when the door is opened, the flap part is pressed down by the finger, and the flap part of the door is stuck on the side of the box. The inner side of the wing is not easy to open. In addition, in the case of an individual packing box provided with a slit in the flap portion of the door, the slit engages with the flap portion on the side of the box more deeply, making it more difficult to open. Therefore, strength is required to open the door, and the flap portion of the door and the side flap portion of the box may be damaged. Although the individual packaging boxes are often discarded after opening, it is preferable to repack the products after taking them out of the individual packaging boxes to confirm, for example, product descriptions or contents. When the individual packing box will not be damaged.

The "packaging container" disclosed in Japanese Unexamined Patent Publication No. 52-45468 has a louver integrated with the door, so the door can be opened in the opening direction without pressing the flap portion down, and the unsealing is easy, but , Due to the thickness of the paper base material, the flat louver board sometimes has insufficient strength, and it loses its function as a finger hook after being bent. In addition, when packing a plurality of "packaging containers" into a packing box, the louver standing vertically from the corner of one end of the box may become an obstacle.

Contents of the invention

Therefore, there is a technical problem that must be solved in order to provide an individual packaging box that is easy to open and does not deform or break even if it is opened and closed repeatedly. The purpose of the present invention is to solve the above-mentioned problem.

The present invention is proposed in order to achieve the above object. It provides an individual packaging box formed by bending a thin plate such as paper or resin, wherein at least one side is a door that can be opened and closed in a hinged manner, and the front end of the door is bent inward. The flap part is inserted into the box to close the door, and it is characterized in that two parallel slits perpendicular to the folding line of the door and the flap part are formed, and the two slits are processed to connect the two slits respectively. The fold line at the front end and the rear end and the fold line connecting the middle part of the two slits and closer to the flap side than the fold line of the door and the flap are thus, when the door and the flap are bent at right angles, are drawn by the two slits. The portion surrounded by the slit is raised in a triangular shape to form a finger hook, and a notch is formed on the side of the box for exposing the finger hook when the door is closed.

In the flap portion of the front end of the hinged door of the individual packing box of the present invention, a triangular finger hook portion is formed, and the door can be simply opened by putting a finger on the finger hook portion. In addition, by providing the finger hook portion, the door can be opened in the opening direction without pressing the flap portion down. Therefore, unlike the conventional method, the flap portion of the door does not get caught in the flap portion on the side of the box. The inner side, or the slit of the fold of the door and the flap part is deeply engaged with the flap part of the box side to prevent the opening of the door, and the door or the flap part is hardly deformed or damaged.

Detailed ways

The present invention is formed into an individual packaging box as follows: In an individual packaging box having a door that can be opened and closed in a hinged manner, two parallel slits perpendicularly intersecting the folding line of the door and the front flap of the door are formed, and processed to form The folding line connecting the front end and the rear end of the two slits and the folding line connecting the middle part of the two slits and shifting closer to the side of the flap than the folding line of the door and the flap part, when bending the door and the flap part at right angles At the same time, the part surrounded by the two slits bulges into a triangle to form a finger hook, and a notch is formed on the side of the box, which is used to expose the finger hook when the door is closed, thereby realizing the following Purpose: Easy to open, even if the door is opened and closed repeatedly, the box will not be deformed or damaged.

Fig. 1 is a developed view of an individual packing box 11 of the present invention. The four sides 12, 13, 14, 15 up and down, left and right are connected up and down in this figure. Here, 12 is called the right side, 13 is the top, 14 is the left side, and 15 is the bottom. In addition, the dotted line shows the folding line f after press working.

On the lateral edge (upper in FIG. 1 ) of the right side 12 is provided a paste portion 16 , and the front edge (right in FIG. 1 ) is connected to a front door 17 . The rear edge (left in FIG. 1 ) of the left side 14 is connected to the rear door 18 , and the front and rear (left and right in FIG. 1 ) of the top surface 13 and the bottom surface 15 are respectively connected to flaps 19 . Front door 17 and rear door 18 are flaps 20 and 21 on the front end side from folding lines f1 and f2 near the respective front ends, and slits 22 in the same direction as folding lines f1 and f2 are formed at both ends of the folding lines f1 and f2. . However, the slit 22 is not essential, and the slit 22 may not be provided, but only the flap parts 20 and 21 may be bent.

Near the front end of the front door 17, two longitudinal slits 23 perpendicular to the folding line f1 are processed and formed, and punched to form the front end (right side in FIG. and three fold lines 24, 25, 26 near the front end. A square area surrounded by two longitudinal slits 23 , a fold line 24 connecting the front end, and a fold line 26 connecting the rear end becomes a finger hook portion 27 to be described later. At the front edge 14a (right in FIG. 1 ) of the left side 14, a notch 28 having a width approximately equal to the interval between the two longitudinal slits 23 of the front door 17 is formed.

Fig. 2A, Fig. 2B and Fig. 2C show the state after the individual packing box 11 of the expanded state of Fig. 1 is assembled into a box shape, and Fig. 2A is a state where the flap portion 20 at the front end of the front door 17 has not yet bent. Then, as shown in Fig. 2B and Fig. 3, after the flap portion 20 at the front end of the front door 17 is bent into a right angle, the finger hook portion 27 is also bent at the above-mentioned three folding lines 24, 25, 26, and because the finger hook portion The folding line 25 in the middle of 27 is displaced closer to the front end side than the folding line f1 of the flap portion 20, so the position of the apex of the finger hook portion 27 is closer to the front end side than the corners of the front door 17 and the flap portion 20 (folding wing side). That is, it has a shape in which the apex of the finger hook portion 27 protrudes from the surface of the curved flap portion 20 .

As shown in FIG. 2C , when the flap portion 20 is inserted into the inside of the left side 14 of the individual packaging box 11 assembled into a box shape, the finger hook portion 27 enters the notch 28 of the left side 14, and the front door 17 is closed. The slits 22 at both ends of the flap portion 20 are engaged with the flap portions 19 of the top surface 13 and the bottom surface 15, whereby the front door 17 is kept in a closed state.

When opening the front door 17, as long as fingers are placed on the finger hooking portion 27 raised into a triangular ridge shape, and pulled in the opening direction, the front door 17 can be pulled open without pressing the flap portion 20, and the folding of the front door 17 can be opened. The flaps 19 of the top 13 and bottom 15 are simply disengaged from the snap fit of the wings 20 , so that the front door 17 is opened.

In this way, when the door is opened, no excessive force is applied to the flap portion 20 of the front door 17 and the flap portions 19 of the top surface 13 and bottom surface 15, so even if the door is opened and closed repeatedly, compared with conventional products, The risk of deformation or damage of the above-mentioned flap parts 19, 20 is also greatly reduced.

In addition, when a plurality of individual packing boxes 11 are arranged and loaded into one packing box, because the apex of the finger hooking portion 27 contacts the side of the adjacent individual packing box 11, the finger hooking portion 27 and the flap portion 20 will It is pressed down, so the individual packaging boxes 11 can be packed in close proximity. At this time, the finger hook portion 27 will not be damaged or deformed. If the individual packing box 11 is taken out from the packing box, the finger hook portion 27 and the flap portion 20 will return to the position shown in FIG. The initial state of 2C.
