Description

  The present invention is a capacity that can be stored by reducing the thickness of a paper box to be stored to a size corresponding to the remaining amount of storage objects when the storage objects stored in a stacked state in the thickness direction are reduced by use. It relates to variable paper boxes.

Conventionally, among the products stored in refrigerators and storages around the kitchen, roux such as curry and stew is sealed in a rectangular paper box that is printed in a resin tray. Sold. The resin tray has a label for opening, etc., but the recipes and doses for cooking are usually printed on the outer paper box. However, the storage space required at the time of purchase was required, and despite the fact that the amount of items contained was reduced, there was an inefficiency that the storage space was not reduced. Moreover, in the refrigerator, the refrigeration efficiency does not improve because the storage space does not decrease.
As a product stored in a similar rectangular paper box, there is a paper box for tissue paper, and when the amount of storage decreases, it is difficult to take out from the top outlet, so a rectangular paper box is used. A fold line provided across the central portion of each side wall height constituting the fold line and an oblique fold line extending from each corner of the rectangular parallelepiped are provided at a point provided inside the predetermined dimension from both ends of the fold line of the long side wall. In the paper box, when the diagonal fold line is folded and the short side wall is folded inward using the fold line, the long side wall is bent outward by the fold line, resulting in a high height of the paper box. It can be in a state of being compressed in the vertical direction. As a result, the tissue paper outlet provided on the upper surface of the paper box is lowered and becomes closer to the uppermost surface of the stored tissue paper, which makes it easy to take out (see, for example, Patent Document 1).

  However, since the paper box having the structure described above is provided with a fold line on the side of the paper box formed in a rectangular parallelepiped and compressed in a bellows shape by the consumer's hand, when the compressing force is removed, the restoring force When the planned compression size, i.e., the usage amount is half, the compressed state is not maintained to about half the storage height, and the height of the paper box becomes unstable, and the desired effect is obtained. There was no case. Further, the side surface to be folded is continuously closed by bonding or the like, and there is no part that serves as a clue to the folding work, so that there is a drawback that it cannot be performed by a simple operation.

  Therefore, an object of the present invention is to solve the above-described problem, and when the amount of objects stored in a stacked state in a paper box formed in a rectangular parallelepiped shape decreases, a paper box by a simple operation It is an object of the present invention to provide a variable capacity paper box that can form a paper box that reduces the height of the paper box and maintains the state by the deformation operation.

  In order to solve the above-mentioned problems, the invention of claim 1 is directed to a trunk portion formed by a side plate, a front plate, a side plate, and a rear plate that are continuously provided, and an ear piece and a top plate that are respectively extended from both ends of the trunk portion. A paper box formed into a rectangular parallelepiped by closing the ear piece, the top of the polymerized top plate, and the bottom of the same, the ear piece, the bottom plate, the ear piece, and the bottom of the polymerized bottom plate. The plate, the top plate, and the bottom plate are provided with fold lines that run vertically, and are inserted into the center portion of the upper and lower edges of the rear plate, respectively, and are each divided by an outward semi-circular opening scheduled cutting line, and the opening cutting scheduled A break planned line that vertically cuts the polymerization top plate and the polymerization bottom plate while continuously expanding from both ends of the wire is drilled, and further, a locking plug is inserted inward from the center of the upper and lower edges of the rear plate, respectively. This is a variable capacity paper box characterized by having a groove.

The capacity variable paper box according to the present invention is configured such that, when an object stored in a stacked state is halved in a paper box formed in a rectangular parallelepiped shape, the height of the rectangular paper box is increased by bending the side plate outwardly. In addition, it can be transformed into a paper box with a hexagonal cross section and can be made into a paper box that does not require useless storage space, and in the case of a product that is stored in a refrigerator or freezer, particularly useless space is eliminated. This has the effect of increasing the efficiency of refrigeration and freezing.
Further, there is an effect that the information described in the paper box can be used even at the next use without losing the description of the article written by printing or the like on the exterior paper box, for example, the recipe for cooking and the amount used.
Furthermore, when performing the above-described operation, the paper box can be opened by a conventional paper box opening operation, that is, a partial tearing of the vicinity of one edge of the paper box and a peeling operation of the end face, and the pushing tearing part is inserted. Since the paper box can be kept deformed by inserting it into a predetermined place as a piece, there is no need for special parts mounting or processing on the paper box, and it is possible to carry out deformation and assembling operations with simple operations. Have.

Further, in the center part of the upper and lower ends of the rear plate 4, substantially semi-circular unscheduled cutting lines x and x straddling two points on the folding lines h and l are perforated at the perforations to insert pieces 14 and 15. Are formed, and then, the C-shaped break lines y and y that cut through the polymerization top plate 12 and the polymerization bottom plate 13 while extending from both ends of the opening and cutting planned lines x and x are perforated, Also, insertion grooves z and z having substantially the same width as the insertion pieces 14 and 15 are engraved at the dimension position half the paper box thickness from the folding lines h and l on the upper and lower sides of the rear plate 4. Yes.

  FIG. 2 (a) is an explanatory perspective view showing the completed state of the embodiment. When assembling from the above-described blank, first, folding is performed using the folding lines a and c, and the sticking plate 5 and the side plate 1 are attached. Connect to form a cylinder. Next, the paper box is erected in a rectangular tube shape using the fold lines a, b, c, d, and the ear pieces 7, 11, the overlapping bottom plate 13, and the bottom plate 9 are folded in turn using the fold lines i, k, l, j, A predetermined position is stuck and the bottom is closed. Next, after storing the storage items 30 such as tray-shaped containers filled and sealed with Carreau etc. in the thickness direction, the ear pieces 6, 10, the polymerization top plate 12, and the top plate 8 are folded into the folding lines e, g, h, f. They are folded in order, stuck in place, and the top is closed to complete the assembly.

FIG. 2B is an explanatory perspective view seen from the rear plate side showing the unsealed completion state of the embodiment. When taking out the stored items from the paper box, any one of the central portions of the upper and lower ends of the rear plate 4 is provided. The top plate 8 or the bottom plate 9 is opened while the expected opening / cutting line x is pushed and then torn using one of the breaking lines y formed in the polymerization top plate 12 or the polymerization bottom plate 13. By opening either the top plate 8 or the bottom plate 9, the stored item 30 can be taken out.
For example, when half of the stored items 30 in a stacked state are used and half are stored, the side opposite to the side opened for taking out the stored items is also opened by the above-described operation, and the stored items 30 are once taken out. After folding the ear pieces 6, 7, 10, 11 into the paper box, abutting each against the inner surface of the side plates 1, 3, and storing the stored items 30 to be stored, the side plates 1 and 3 are folded into the folding lines m and n. By using and bending the paper box outward, the distance between the front plate 2 and the rear plate 4 is reduced to approximately half, the top plate 8 and the bottom plate 9 are bent to half the height by the folding lines o and p, and the unsealed cutting line The insertion pieces 14 and 15 formed by cutting x and x are inserted into the insertion grooves z and z, respectively, so that the remaining storage items as shown in FIG. Stored. In addition, since the insertion pieces 14 and 15 are inserted and locked in the insertion grooves z and z, the original state is not restored again, and the storage space can be reduced.
