Description

[Detailed description of the invention] [Industrial application field] This invention consists of a tray with an open top surface that is used for packaging fruits and vegetables, and a cylindrical tray cover that covers the outside of the tray. This relates to packaging boxes.

[Conventional technology]

Conventionally, a cardboard tray 1 used for packaging fruits, vegetables, etc. has a structure with an open top surface as shown in FIG. There is a structure in which a side plate 5 and an end plate 6 are erected on each end side 4.

Trays 1 with their tops open in this way allow items to be seen from above, so they can be conveniently displayed in stores, but when stacked, there is a risk that the upper trays 1 may fall into the lower trays. .

For this reason, conventionally, when trays 1 are stacked, the bottom wall 2 of the upper tray 1 is supported on both ends of the upper surface of the opposing side plates 5 to prevent the upper tray 1 from falling into the lower tray 1. Upper frame plate 7
has been established.

The upper frame plate 7 is connected to the upper side 8 of the end plate 6, as shown in the developed view of FIG. and,
Locking pieces 9 are formed on both sides of the upper frame plate 7, and the locking pieces 9 are formed into slits 10 formed at the bent portions of the outer plate 5a and inner plate 5b of the side plate 5 formed in a double wall structure. It is inserted into and locked.

[The problem that the idea aims to solve]

Incidentally, in recent years, with the spread of home delivery services, it has become common for fruits, vegetables, and the like to be sent directly from production areas to households as souvenirs and gifts using home delivery services.

In such cases, it is not possible to use the above-mentioned open-top tray for delivery by courier service, so conventionally, the item is transferred to another packaging box that does not have an open top for delivery. There are many things.

However, there are problems in that transferring the item to another packaging box is time-consuming and the original packaging box is wasted.

Therefore, this invention is intended to enable products to be delivered directly by courier service without having to be transferred from a tray with an open top to another packaging box.

[Means to solve the problem]

In order to solve the problem of the upper frame board, this idea was
A cylindrical tray cover 20 consisting of a top plate 22, a bottom plate 23, and both side plates 21 is placed on the outside of the tray 1 with its top open, and the slit 10 formed in the bent portion of the top end of the side plate 5 of the tray 1 is covered. An insertion piece 27 is formed on the tray cover 20 at the corresponding position, which is defined by two vertical cuts 25 extending from the top plate 22 to both side plates 21 and a cross cut 26 connecting the lower ends of the vertical cuts 25. However, this insertion piece 27 is inserted into the slit 10 on the upper end surface of the side plate 5 of the tray 1.

[Effect]

By the above means, the outside of the tray 1 is covered with the cylindrical tray cover 20, and the tray cover 20 is covered with a cylindrical tray cover 20.
Since the insertion piece 27 of No. 0 is inserted into the slit 10 of the tray 1, the tray 1 does not come out from the cylindrical tray cover 20, and the tray 1 and the tray cover 20 are integrated.

〔Example〕

Next, an example of this invention will be described.

The packaging box according to this invention consists of a tray 1 and a cylindrical tray cover 20 that covers the outside of the tray 1.

The tray 1 is assembled from die-cut cardboard as shown in the exploded view of FIG.

That is, side plates 5 and end plates 6 are connected to opposing sides 3 and opposing edges 4 of the rectangular bottom wall 2, respectively. The side plate 5 includes an outer plate 5a and an inner plate 5b.
It has a double structure with overlapping. For this reason, the outer plate 5a is connected to both sides 3 of the bottom wall 2, and the inner plate 5b is connected to the upper side of the outer plate 5a via a bent plate 5c forming a bent portion. A locking protrusion 12 is provided protruding from the lower side 11 of the inner plate 5b, and the locking protrusion 12 is fitted into a locking hole 13 formed along the side edge 3 of the bottom wall 2. Furthermore, flaps 14 are formed on both sides of the end plate 6 to be inserted between the inner plate 5b and the outer plate 5a, which are set perpendicularly to the bottom wall 2. 5b and the outer plate 5a, the end plate 6 and side plate 5 are supported at right angles to the bottom wall 2. Additionally, end plates 6 are provided on both sides of the inner plate 5b.
The flap 15 is connected to the inner surface of the flap 15. On the other hand, an upper frame plate 7 is connected to the upper side 8 of the end plate 6. A locking piece 9 is formed on both sides of the upper frame plate 7, and a slit 1 is inserted into the locking piece 9.
0 is formed on the bent plate 5c on the upper side of the inner plate 5b and the outer plate 5a, and the locking piece 9 is inserted into this slit 10. A hook piece 16 is provided on one side of the locking piece 9, and when the locking piece 9 is inserted into the slit 10, the hook piece 16 is inserted into the slit 10.
0 to prevent the locking piece 9 from coming off. Further, a triangular notch 17 that is continuous with the slit 10 is formed in the outer plate 5a, and this notch 17 facilitates insertion of the locking piece 9 into the slit 10. .

Next, the tray cover 20 is assembled from die-cut cardboard paper as shown in the exploded view shown in FIG.

That is, the side plate 21, the top plate 22, the side plate 21,
The bottom plate 23 and the joint piece 24 are successively connected to each other via a bending line. The joint piece 24 is connected to the side plate 21
It is then joined with adhesive, staples, etc.
The sizes of the upper surface plate 22 and the lower surface plate 23 are slightly larger than the size of the bottom wall 2 of the tray 1. Further, the size of the side plate 21 is also formed to be slightly larger than the size of the side plate 5 of the tray 1.

Top plate 22 and side plate 2 of the tray cover 20
When the tray cover 20 is placed over the outside of the tray 1, a corner portion formed by An insertion piece 27 is formed by two vertical cuts 25 and a cross cut 26 connecting the lower ends of the vertical cuts 25. A hook piece 28 is formed on one side of the insertion piece 27 to be caught in the slit 10 of the tray 1 when the insertion piece 27 is inserted into the slit 10. In this embodiment, this insertion piece 27 is inserted into the tray 1.
Although four insertion pieces 27 are formed to match the number of slits 10, only one insertion piece 27 may be used.

Furthermore, a finger hole 29 is formed below the cross-cut 26 constituting the insertion piece 27 in the side plate 21, and is continuous with the cross-cut 26.

Next, when combining the tray 1 and the tray cover 20, insert the tray 1 into the tray cover 20 as shown in FIG. 3, and then insert the insertion piece 27 of the tray cover 20 as shown in FIG. Raise it as shown in FIG. 2 and push the insertion piece 27 into the slit 10 of the side plate 5 of the tray 1.

Thereafter, by pasting a slip with the destination etc. written on the surface of the top plate 22 of the tray cover 20, the tray cover 20 can be used as it is as a packaging box for home delivery.

[Effect of idea]

According to this invention, as described above, a cylindrical tray cover 20 is placed on the outside of the tray 1 whose top surface is open.
By inserting the insertion piece 27 of the tray cover 20 into the locking slit 10 of the upper frame plate 7 of the tray 1, attach the tray cover 20 that covers the tray 1 and its outside using adhesive tape or the like. Since it can be integrated without any additional work, it can be used as it is as a packaging box for home delivery.
