Description

  The present invention relates to a stacking box that covers a mountain-shaped upper surface of a square paper pack used as a container for selling dairy products such as cream.

  First, in the utility model registration No. 3070641, the applicant consists of a main body of a thin resin molded product having three chevron protrusions and a bottom plate of a chevron thin resin molded product fitted into the main body from below. In addition, he proposed a stacking box that accommodates a mouthpiece and a squeeze bag for dairy products. This stacking box is convenient when a dairy product is in the paper pack, and a base and a squeeze bag are attached, and when the paper pack is empty, the main body can be used as an overcap for other paper packs. Convenient.

With regard to this type of stacked box, in recent years, with the diversification of articles accommodated therein, an increase in the capacity of accessories has been demanded. In addition, it is desired to contribute to the stability of the multistage display of the square paper pack as well as to reduce the cost. ,
Utility Model Registration No. 3070641

  The present invention has been made to meet the above-mentioned demands, and the problem is to provide a stacking box that has a large capacity for storing accessories, stabilizes multistage display of rectangular paper packs, and reduces manufacturing costs. It is to be.

  In order to solve the above-mentioned problems, the present invention adopts a thin resin molded product main body comprising a rectangular top plate and front, rear, left and right side plates hanging from the four sides of the top plate, and fitted into the main body from below. In the stacking box composed of the bottom plate of the chevron-shaped thin resin molded product to be used, when the mountain-shaped top extension direction is the front-rear direction, the top plate is adjacent to the top and bottom in the center of the left and right, and the two troughs extending in the front-rear direction are Is characterized in that two grooves communicating with the surfaces of the two valley portions are formed, and a protruding portion that enters between the two rear surfaces of the adjacent valley portions is formed on the bottom plate.

  The stacking box forms a polygonal columnar space having a bottom plate slope as a bottom surface between the main body and the bottom plate. In this space, the accessory of the square paper pack is accommodated. In the previous case, this space has a triangular prism shape. However, according to the above-described means, the stack box of the present invention has a rectangular shape, and its height is higher than that of the previous triangular shape. Increases significantly. Therefore, the stacking box of the present invention can cope with the diversification and enlargement of the square paper pack accessories. In addition, since the stacking box of the present invention has a flat upper surface and is wide, the square paper pack covered with the stacking box can be stably displayed in multiple stages.

  In a stacking box consisting of a thin resin molded product main body with an open bottom and a bottom plate of a chevron thin resin molded product that fits into the main body from below and covers the top chevron square paper pack, the main body and the bottom plate are transparent. It is preferable to use a PET resin and partially provide reinforcing ribs. When the direction in which the top of the chevron extends is the front-rear direction, the main body is a rectangular top plate that is substantially the same as the cross section of the paper pack, and the front, back, left, and right side plates that hang from the top plate and overlap the front, back, left, and right sides of the paper pack With. The top plate has two W-shaped valleys that are adjacent to each other at the center of the left and right and extend in the front-rear direction, the front and rear side plates have two W-shaped grooves that communicate with the surface of the valleys, and the bottom plate has the adjacent valleys. A pleated ridge that enters between the back surfaces of the parts is formed.

  When embossing is performed on the top surface of the top plate, the sideslip of the stacked square paper packs is restricted, so that an accidental fall of the square paper packs can be prevented. Further, when a receiving portion that opens downward is formed at the upper end of the narrow space at the center of the back of the top plate, and an insertion portion that is elastically detachably fitted into the concave portion is formed at the upper end of the protruding portion of the bottom plate, Since the sealing process for integrating the bottom plate is omitted, not only the manufacturing cost is reduced, but also the post-use of the main body is not restricted by the seal mark.

  A stacking box of the present invention will be described based on an embodiment shown in the drawings. 1 and 2 are a plan view and a longitudinal sectional view of an embodiment, and FIG. 3 is an exploded longitudinal sectional view of another embodiment.

  As shown in FIGS. 1 and 2, the stacking box includes a rectangular box-shaped main body 1 having an open bottom surface, and a mountain-shaped bottom plate 2 fitted into the main body 1 from below. The main body 1 and the bottom plate 2 are transparent and thin PET resin molded products, and reinforcing ribs 4 and 5 are partially formed.

  When the direction in which the top of the chevron extends is the front-rear direction, the main body 1 has a rectangular top plate 6 that is substantially the same as the cross section of the paper pack 3 and the front and rear sides of the paper pack 3 that overlap the front, rear, left and right sides of the paper pack 3 Left and right side plates 7, 8, 9, 10 are provided. The surface of the top plate 6 is embossed.

  The top plate 1 is formed with two W-shaped valleys 11 adjacent to each other at the center of the left and right sides and extending in the front-rear direction, and the front and rear side plates 7 and 8 have two W-shaped grooves 12 communicating with the surface of the valley 11. Is formed. The bottom plate 2 is formed with a pleated ridge 14 that enters a gap 13 between the back surfaces of the adjacent valleys 11 and 11. ,

  Accessories such as a cap 15 and a squeeze bag 16 are placed inside the inverted main body 1, the bottom plate 2 is fitted inside, and the protrusion 14 is inserted into the gap 13. Next, the main body 1 and the bottom plate 2 are assembled together by a sealing process such as sealing tape or heat sealing. When the stacking box in which the main body 1 and the bottom plate 2 are integrated is put on the top surface of the square paper pack 3 containing dairy products such as cream, the bottom plate 2 overlaps the top surface of the square paper pack 3 and The side plates 7, 8, 9, 10 overlap the front, back, left and right side surfaces of the square paper pack 3.

  Since the space for accommodating the accessory between the main body 1 and the bottom plate 2 is a rectangular column having a relatively large volume, a base 15 and a squeeze bag 16 that are larger than the conventional one can also be installed. Further, since the surface of the top plate 6 is flat and wide, the square paper pack is stable even when stacked in multiple stages. In addition, the embossing of the top plate surface prevents the rectangular paper pack from slipping, so that it is possible to prevent an accidental fall of the square paper pack displayed in multiple stages.

  In another embodiment shown in FIG. 3, recesses are formed on the left and right surfaces of the upper end of the protrusion 14 to form a neck-shaped insertion portion 17, and recesses are similarly formed on the left and right surfaces of the upper end of the gap 13. Thus, the narrow receiving portion 18 is formed. When the bottom plate 2 is fitted into the main body 1 and the protrusion 14 is inserted into the gap 13, the insertion portion 17 is elastically fitted to the receiving portion 18 so that the main body 1 and the bottom plate 2 are integrated. Therefore, the sealing process for integrating the main body 1 and the bottom plate 2 is not necessary, and the manufacturing cost is reduced.

  The insertion part 17 and the receiving part 18 are elastically detachable, and when one is pulled slightly stronger than the other, the insertion of the insertion part 17 and the receiving part 18 is separated. Configurations and effects other than those described above are the same as those in the previous embodiment.

Plan view of the longitudinal section, FIG. 1 is a longitudinal sectional view of the embodiment of FIG. The exploded longitudinal cross-sectional view of another Example.
