DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container comprising a thin-walled container body made of a synthetic resin sheet or the like for packing various items such as foods such as fruits, vegetables and fresh fish, and a hard plate-shaped lid. In particular, it is configured to facilitate opening and closing of the lid.

[0002]

2. Description of the Related Art A conventional thin-walled container 1 is formed by blow molding or vacuum molding of a synthetic resin sheet. As shown in FIG. 4, a concave portion 3 surrounded by a flat peripheral portion 2 is formed. After the recess 3 is filled with an article, the sheet is closed with another flat thin synthetic resin sheet (not shown), and the synthetic resin sheet is sealed to the peripheral portion 2 of the thin-walled container 1. .

[0003]

However, as described above,
Closing with a thin sheet of synthetic resin could damage the items in the container when stacked, so stacking in multiple layers was not possible. In addition, since it is difficult to print and display the source and quality of an article on a thin synthetic resin sheet serving as a lid, paper with the source and quality printed is enclosed.

[0004] Further, when packing a thin-walled container with a product having a small amount of water and not leaking, it is desirable that the lid can be easily opened and closed, and it is necessary that the product in the thin-walled container is not damaged even when stacked.

[0005]

Means for Solving the Problems A concave portion 3 for packing one or more articles surrounded by a peripheral portion 2 and a rib 23 formed on the peripheral portion 2 so as to protrude upward, and a wall surface inside the rib 23 is provided. An angle between the inner peripheral surface 24 and the flat surface 22 inside the peripheral portion 2 is formed at an acute angle, and at least one portion of the rib 23 is cut away to form a thin-walled container book having the same flat surface as the peripheral portion 2.
An ear 41 that has substantially the same shape as the body 1 and the flat surface 22 inside the rib 23 and that fits into the flat surface 25 with the rib 23 cut out.
And a hard plate-shaped lid 4 protruding.

[0006]

When the angle formed between the top surface and the inner wall surface 24 of the rib 23 projecting upward from the peripheral portion 2 is formed at an acute angle, the space a inside the top of the rib 23 becomes the space b inside the bottom of the rib 23. The thickness of the ear 41 is made of thick paper such as cardboard or a hard synthetic resin sheet.
If the width c of the lid is larger than the distance a between the tops of the ribs 23 and smaller than the distance b between the bottoms of the ribs 23, the lid 4 is strongly pressed.
Can be easily dropped. Also, hold the ear 41
The lid 4 can be easily removed by lifting
You.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A thin-walled container 1 of the present invention is made by blow molding or vacuum molding a synthetic resin sheet.
As shown in the perspective view of FIG. 1, there is a recess 3 for packing one or more items surrounded by a peripheral portion 2, the recess 3 having a shape according to the items to be packed and the number thereof, and A rib 23 protruding upward so as to surround the concave portion 3 is formed on the peripheral portion 2, and a part of the rib 23 is cut out to form the same flat surface 25 as the peripheral portion 2.

As shown in an enlarged view of the peripheral portion 2 in the longitudinal sectional view of FIG. 2, the rib 23 protrudes upward from the outer flat surface 21 and the inner flat surface 22, and the inner wall surface 24 of the rib 23. The angle between the inner wall and the inner flat surface 22 and the angle between the wall surface 24 and the top of the rib 23 are acute angles. Therefore, the interval a inside the top of the rib 23 is set smaller than the interval b inside the bottom of the rib 23 (a <b).

The lid 4 as shown in FIG. 3 is fitted into a step formed by the inner wall surface 24 of the rib 23 and the inner flat surface 22. The cover 4 is preferably made of thick paper such as cardboard or a hard synthetic resin sheet.
Are set to be larger than the interval a at the top and smaller than the interval b at the bottom of the rib 23 (a <c <b).

The thin-walled container 1 is made of a synthetic resin sheet and is easily deformed, so that it can be easily dropped into the step by strongly pressing the lid 4.

As shown in FIG. 3, the lid 4 has an ear 41 and a hole 42 in which a finger is fitted.
The lid 4 can be easily removed by lifting the ear 41 or putting a finger into the hole 42 and pulling it up.

If the ears 41 of the lid 4 are bent downward after the lid is closed, the ears 41 do not protrude.

[0013]

As is clear from the based on the above embodiments description, according to the present invention, according to the container of the present invention, the ear portions 41 of the lid 4 Wotsu
The lid 4 can be easily opened and closed by lifting it up , and if the lid 4 is made of a hard sheet, the effect of preventing the items in the container from being crushed even when the containers packed with the items are stacked. Can play. Also, the lid 4
If thick paper such as paper is used,
The firing temperature is low and no gas that causes pollution is generated.
No.
