Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a shock-absorbing container used for transporting fragile items such as strawberries.

BACKGROUND TECHNOLOGY Traditionally, strawberries and the like have been transported by forming a storage part made of a plastic sheet, which stores the stored items, and having a concave edge around the periphery, and a plastic sheet, which covers the storage part, and Containers consisting of a lid and a lid with an overlapping rim are widely used.

In addition, since this container does not have any cushioning material and the stored items are easily damaged, this container is made of a foam sheet and has an edge that fits inside the storage section and rests on the edge of the storage section. Containers have been devised that include additional cushioning material that recesses.

Furthermore, in order to increase the shock absorption effect of this cushioning material, a container has been devised in which the cushioning material is suspended by the edge and has a space between it and the bottom of the storage section.

Problems that the invention aims to solve Containers with the above-mentioned cushioning material move and become uneven due to vibrations during transportation, etc., and the edge of the cushioning material may pull out from the edge of the storage part or shift and become misaligned. It may cause

In order to prevent such inconvenience, the edge of the cushioning material may be sandwiched between the edge of the storage section and the edge of the lid, and the entire structure may be fixed with a stapler.

However, the stapler needles are metal, and when storing food items such as strawberries, there is a great danger if they accidentally get mixed into the stored items, and if transported in a refrigerator, they may rust due to moisture. , the use of a stapler is not recommended.

Therefore, the present invention was devised for the purpose of obtaining a container that can securely hold a cushioning material without using a stapler.

Means for Solving the Problems In other words, the present invention provides, in addition to the container having the above-mentioned cushioning material, a missing portion formed on the edge of the cushioning material and directly joining and welding the edge of the storage portion and the edge of the lid; The shock-absorbing container is characterized in that it has an engaging part formed on the edge of the storage part or the edge of the lid, which engages with the edge of the cushioning material to prevent removal and movement.

Function Therefore, in the container of the present invention, the edge of the storage part and the edge of the lid are joined at the missing part of the edge of the cushioning material, and are bonded by heat or ultrasonic welding, and the edge of the storage part or the lid is formed on the edge of the storage part or the lid. The edge of the cushioning material can be engaged and fixed with the engaging portion.

Embodiments Hereinafter, embodiments illustrating the present invention will be described in detail.

The shock absorbing container 10 shown in FIGS. 1 to 3 is
It consists of a storage section 11, a lid 12, and a cushioning material 13. Both the storage section 11 and the lid 12 are formed from a single plastic sheet using a vacuum forming method or the like.
1 has a concave shape with an edge 14 around the periphery;
Storage items (not shown) can be placed inside, and the lid 12 is plate-shaped and has a rim 15 around it.
By bending the hinge part 16 provided between the storage part 11 and the lid 12, the lid 12 can be attached to the storage part 11.
, and both edges 12 and 15 overlap. The lid 12 may have a plate shape as shown in the illustrated example, or may have a shape that bulges upward, or may be formed separately from the storage portion 11.

The cushioning material 13 is formed from a foam sheet using a vacuum forming method, etc., and has a concave shape with an edge 17 around the periphery, and fits into the storage section 11, and the edge 17 is formed from the edge 14 of the storage section. Published in Furthermore, cushioning material 1 in this example
3, a space 18 is formed between it and the bottom of the storage section 11, and the space 18 is suspended from the edge 17. Note that this space 18 may not be provided, that is, the bottom of the cushioning material 13 may be in contact with the bottom of the storage section 11.

The edge 17 of this cushioning material 13 is provided with a cutout 19, and the edges 14 and 15 of the storage portion 11 and the lid 12 are directly joined at this portion, and welded 20 using heat, ultrasonic waves, etc. Ru.

Engagement parts 21 and 22 made of protrusions are formed on both the edge 14 of the storage part and the edge 15 of the lid, which bite into and engage with the edge 17 of the cushioning material (see Figure 4) to prevent removal and movement. do.

As shown in FIG. 5, this engaging part 2 is formed by protrusions on the edge 14' of the storage part and the edge 15' of the lid.
1' and an engaging part 22' consisting of a recessed part may be provided, and the edge 17' of the cushioning material 13' may be sandwiched between the engaging parts 21' and 22'. Although not shown, it goes without saying that the engaging portion may be provided only on the edge 14 of the storage portion or only on the edge 15 of the lid.

Furthermore, as shown in the container 10'' shown in FIGS.
9'', welded here 20'', and use the portions of the edge 14'' of the storage portion 11'' and the edge 15'' of the lid 12'' near this welded 20'' as the engaging portions 21'' and 22'', and here It is also possible to hook and fix the edge 17'' of the buffer material 13''.

Effects of the Invention As described above, the shock-absorbing container of the present invention can connect the storage part and the lid without using a stapler, and at the same time can stably fix the cushioning material by the engaging part. Therefore, dangers caused by the stapler can be prevented, and inconveniences such as displacement of the cushioning material during transportation can also be prevented.

In particular, since the present invention can effectively fix the position of the edge of the cushioning material, it is extremely effective in a type of container in which the cushioning material is suspended.
