Description

[Detailed description of the invention] This invention is a simple container used to pack and sell various foods, etc., and the lid can be completely fixed in place, and the lid can be opened instantly with a simple operation. .

Conventionally, this type of container has been made by vacuum forming a thin plastic plate, as shown in Figure 1, and is made by integrally molding a cover body and a continuous lid body, each having a concave portion corresponding to the shape of the stored item. Store food or other items in the recess of the case, fold the lid at the rear continuous edge and fold it over the top of the case to close the lid, and weld the front overlapping edge. , or it is fixed by partially hooking it with staples etc.
When opening these lids, it is necessary to cut open the welded part or pry open the latch part with a tool, which is time-consuming and often causes damage to the stored items, making it very inconvenient. It was hot.

The present invention is intended to solve the above problems, and its purpose is to provide a convenient packaging container whose lid can be completely fixed and closed, and whose lid can be opened safely and quickly with a simple operation. .

Next, the configuration, operation, and effects of the present invention will be explained with reference to the drawings showing the embodiments of the present invention.

Reference numeral 1 denotes a vacuum-formed container made of a thin plastic plate, which is used to store and sell food products such as chicken egg packs.
Recesses 3, 3 convenient for inserting and storing article B...
Each box body 4 and the lid body 5, each having a recess, are integrally molded continuously by the rear edge 2a.
The cover body 4 is folded along the intermediate bend line 2' and overlapped from above the cover body 4 to close it.

After that, the structure of fixing the lid body 5 to the housing body 4 according to the present invention is as shown in the front view of FIG. 2 and the plan view of FIG. Through-holes 6, 6, . 7' is inserted into the first through hole 6 from below to above, and pulled in the lateral direction.
The knot 7' is hooked to the lower end of the through-hole 6, and then inserted into the next through-hole 6 from the top to the bottom. Tie the front end at the end and secure by hooking. It goes without saying that there are various configurations for hooking both ends of the tightening thread 7 in addition to the above. The overlapping edge 2b where the tightening thread 7 is inserted and sewn through the through holes 6, 6, etc. is not only limited to the front edge, but also partially to other edges or to the entire periphery as necessary. In some cases, it may be enforced.

It is inappropriate for the distance d between the through holes 6, 6... to be too small, and when opening the lid as described later,
Appropriate spacing is required so that the inserted tightening thread 7 can be smoothly pulled out.

The tightening thread 7 according to the present invention is not sewn by intertwining the upper and lower threads as in the conventional sewing machine, but by inserting a single tightening thread 7 in a zigzag pattern, and the through-hole 6 is not formed. , which is inserted at the tip of the insertion needle at the same time as the tightening thread 7 is inserted, and the suturing process is as follows:
This can be easily done by hand or by simple mechanical operation.

Moreover, against the force in the direction of opening the lid, the tensile stress of the tightening thread 7 does not act on it and cause it to break easily, making it extremely sturdy.

Since the closure fixing of the present invention has the above-mentioned structure, when opening the lid, one of the knots of the tightening string 7 is untied,
When the other end is pulled horizontally with a fingertip, the entire length of the tightening string 7 is finally pulled out while sliding in the through hole 6 one after another, and at this point the closure of the case body 4 and lid body 5 is completed. The fixation is released and the lid can be opened easily.

As described above, the present invention has great practical effects, as it is possible to completely secure the lid closed with simple processing, and the lid can be opened easily and easily without damaging the stored articles.
