Description

[Detailed description of the invention] (Field of industrial application) The present invention stores a large number of packaged articles in a plurality of trays, wraps them integrally with a single lid plate, and This relates to a packaging paper box that can be removed and used for display as is.

(Prior Art) Generally speaking, there are various types of packaging boxes that can be used for exhibition purposes, but none have been found that have a structure in which a pair of trays having openings on the sides are wrapped in a single lid. As for this kind of packaging box, the invention of the earlier application related to the same applicant was Utility Application No. 80208 (1983)
183318)).

The invention of this earlier application is superior in that flaps are attached to both sides of the lid material that wraps around the tray and closes the opening of the tray, making it extremely convenient to put on and cut out the lid material. The edge of the lid material located on the side of the tray where there is no opening is separated and merely touches the top edge of the tray, and a small gap remains between the lid material and the top edge of the tray. .

This is a packaging form where gaps may remain,
If the packaging is slightly misaligned and the gap widens even a little, dust will enter the packaging box through the widened gap during transportation, when it is being transported to a warehouse, or when it is being stored, which is not only undesirable from a sanitary standpoint, but also when displayed at a store. Even in this case, there is a drawback that the dust covering the product must be removed, which requires extra work.

(Purpose of the invention) The present invention was made in order to eliminate these drawbacks, and the purpose is to provide a packaging paper box that can be used for exhibition purposes and which does not allow dust to get inside even if the packaging is a little poor. It is something to do.

(Structure of the invention) The invention made to achieve this purpose is:
A pair of trays having substantially U-shaped openings on opposing sides are arranged side by side with their non-opening sides abutting each other, and the lid material placed on the top of the tray has flaps on both sides of the top plate. In a packaging paper box having a structure in which the flaps are arranged in a row and are positioned so as to close the opening and are bonded near the bottom, the upper end of the side that does not have an opening and is located outside of the tray, or A packaging paper box for display and use, which is characterized by having tongues for dust prevention on both sides where the flap of the lid material is not continuous, and the tongues for dust prevention are provided in the part where there is a gap. For,
Even if the packaging is a little poor, it can prevent dust from entering.

(Embodiment) Next, the present invention will be explained in more detail with reference to the illustrated embodiment.
The box is used to store products in parallel. As shown in FIG. 2, one structure of this tray is that side surfaces 7, 8, 9, and 10 are integrally connected to the bottom surface 2 through folds 3, 4, 5, and 6, and the inside thereof Approximately U-shaped openings 11, 12 are formed in a pair of opposing side surfaces 9, 10, and inner reinforcing pieces 17, 18 are formed on both sides of these side surfaces through folds 13, 14, 15, 16. , 19, and 20 are arranged in series. A tongue portion 21 for dust prevention of an appropriate length is integrally connected to one of the other side surfaces 7 and 8.

As shown in FIG.
stand up against the bottom surface 2 first, and each inner reinforcing piece 1
7, 18, 19, and 20 are each bent inward, and then the other side surfaces 7 and 8 are stood up and adhered to the outside of each inner reinforcing piece. When assembled in this manner, the side surfaces 7 and 8 have a double structure due to the inner reinforcing pieces, and their strength is significantly increased.

Two trays 1 assembled in this way are used, and they are placed in parallel with the sides without the tongue 21 for dust prevention in contact with each other, since there is no internal partition for storing items such as products. The trays are mechanically and automatically loaded into each tray, and the tongues 21 for dust prevention are folded inward.

The lid material 22 that is placed on the top of the tray 1 has flaps 2 through folds 24 and 25 at positions that close both side edges of the top plate 23, that is, the openings 11 and 12 on both sides.
6 and 27 are installed in series. These flaps are formed to have a width approximately the same as the height of the side surface of the tray 1, and are provided with perforations or cut-off means 28, 29 such as cut tape near the free end, and from the cut-off means to the end side are glue allowances 30, 31. It is set as. Glue-shaped tongues 32 and 33 of appropriate length are formed on the other side edge of the top plate 23, that is, on both side edges corresponding to the side surfaces 7 and 8 without openings.

Glue margins 30, 3 of the lid material 22 formed in this way
1 and the insides of the tongues 32 and 33, respectively, and then place the top plate 23 on top of the parallel trays 1, bend the flaps 26 and 27 downward, and attach the side surfaces 9 and 10. Glue it near the bottom. At the same time, the tongue portions 32 and 33 are also bent downward and adhered near the upper portions of the other side surfaces 7 and 8. By adhering in this manner, the tray 1 and the lid material are bonded together in a stable state without any large gaps, and the packaging is completed as shown in FIG. 4. Although the tongue portion for dust prevention has been described for both the tray and the lid, it is sufficient to provide it only for one of them.

When displaying the product at a supermarket or retail store, the lid material 22 is removed by cutting off the cutting means 28 and 29, and the tongue portions 32 and 33 are also cut off, so that the side openings are immediately opened and the product can be seen. , can be displayed by stacking multiple tiers.
And the side of each tray near the bottom has a glue allowance of 30.3
1, it has excellent strength, and together with the aforementioned inner reinforcing pieces 17, 18, 19, and 20, it has great stability when stacked, and the load does not collapse.

(Effect of the invention) As explained above, the packaging paper box according to the invention is a packaging paper box consisting of a pair of trays having an opening and a lid material that covers the upper part of the tray and the opening. By providing tongues for dust prevention on the upper ends of the side surfaces that are located on the outside and have no flaps, or on both side edges where the lid flaps are not connected, the lid material can be mechanically removed from the trays that are placed side by side. Even if the lid is in poor condition, there will be no gap between the lid and the tray, and dust will not get inside during transportation or storage in the warehouse, making it hygienic and displayable. This provides excellent effects such as eliminating the need for extra work such as brushing off dust at times.

Further, since precision is not required in the closing work, excellent effects such as high workability are achieved.
