Description

[Detailed Description of the Invention] Industrial Field of Use This invention relates to a sealed container for storing, for example, nails or snacks such as potato chips.

Prior Art and its Problems Conventionally, this type of closed container has been used in which a lid is forcibly fitted into the opening of a bottomed square tube or bottomed cylindrical container body. However,
Such containers are difficult to open, and it is necessary to separately prepare an opening tool to open the lid, or to provide an opening handle on the lid.

This invention was made in view of the above-mentioned circumstances, and aims to provide a sealed container that is easy to open.

Means for Solving the Problems The airtight container according to this invention has a bottomed cylindrical container body and a clamping part that is forcibly fitted into the top opening of the container body and has a substantially inverted U-shaped cross section on the periphery. The upper end of the peripheral wall of the container body is clamped by a clamping part, and a break line for forming a roughly U-shaped opening finger insertion part is formed on the peripheral wall of the container body from the upper end. be.

In the above, the container body is made of synthetic resin, paper, a laminate of paper and synthetic resin, a laminate of paper and metal foil, a laminate of synthetic resin and metal foil, or the like. Further, the shape of the container body is a cylindrical shape with a bottom, a prismatic cylindrical shape with a bottom, or the like. The lid is made of metal or synthetic resin. As the breaking line, a perforation, a cut groove, a broken line cut groove, etc. are used, and the type of breaking line to be used is determined by taking into consideration the type, properties, etc. of the contents.

EXAMPLE This invention will be explained below with reference to the drawings.

In FIG. 1 and FIG. 2, the closed container 1 is
A metal lid 3 is forcibly fitted into the top opening of a bottomed cylindrical paper container main body 2, and a peripheral wall 2a of the container main body 2 is
A substantially U-shaped breaking line 5 for forming a finger insertion part for opening is provided from the upper end.

The lid 3 has a circular shape, and a clamping portion 3a having a substantially inverted U-shape in cross section is provided on the periphery of the lid 3 in an upwardly projecting manner. A winding edge portion 3b is provided at the lower edge of the outer wall of the clamping portion 3a. Then, the lid 3 is pushed into the top opening of the container body 2 from above, and the upper end of the peripheral wall 2a is inserted into the clamping part 3.
a and the winding edge 3b sinks into the outer circumferential surface of the peripheral wall 2a, so that the peripheral wall 2a is firmly clamped by the clamping part 3a, and the lid 3 is forcibly fitted into the top opening of the container body 2. ing. Break line 5
consists of perforations.

A method for opening the airtight container 1 will be explained with reference to FIGS. 3 to 5. First, press firmly with your fingers from the outside the part surrounded by the break line 5 (see Figure 3),
This portion is broken to form a finger insertion portion 4 consisting of a U-shaped notch. At this time, the portion originally surrounded by the break line 5 remains in a state of being sandwiched between the clamping portions 3a and folded inward (see FIG. 4). This remaining portion is indicated by 6. If the object contained in the container 1 is smaller than the finger insertion part 4, the lid 3
can be taken out from the finger insertion part 4 while remaining fitted into the top opening of the container body 2 and using the remaining portion 6 as a guide. If you need to remove lid 3,
Next, when a finger is inserted into the finger insertion part 4 and the lid 3 is strongly pulled upward (see FIG. 5), the upper end of the peripheral wall 2a comes out of the clamping part 3a and the lid 3 is removed. Break line 5
If the portion surrounded by is pushed through, the upper edge of the peripheral wall 2a will deform and the lid 3 will easily come off. If you need to put the lid 3 on again after taking out the contents inside the container body 2, bend the remaining part 6 outward and put it back on.
is pushed in from above and fitted into the top opening of the container body 2, and the upper end of the peripheral wall 2a is clamped by the clamping portions 3a. Then, the notch 4 can be closed with the remaining portion 6 attached to the lid 3. As a result, the contents can be prevented from spilling out of the container 1 through the notch 4.

FIGS. 6 to 8 show variations of the breaking line.

Break line 15 shown in FIGS. 6 and 7
is composed of one cut groove having a cross-sectional shape, and has a slightly different shape from the break line 5. Further, the cross-sectional shape of the breaking line 15 is V as shown in FIG.
It may be a shape.

Effects of the invention According to the airtight container of this invention, when opening the lid 3, the part surrounded by the break lines 5 and 15 is broken with a finger to form the finger insertion part 4, and the finger is inserted into the finger insertion part 4. and pull it upward to remove the peripheral wall 2a of the container body 2.
By pulling out the upper end from the clamping portion 3a of the lid 3, the forced fitting of the lid 3 can be removed, making opening easier. Therefore, there is no need to provide a handle for opening the lid 3 or to prepare a separate opening tool. Furthermore, the shape of the lid 3 can be made simple and clear, and an inexpensive lid can be used. Further, when the finger insertion portion 4 is formed, the portion originally surrounded by the break lines 5 and 15 remains in a state of being sandwiched between the clamping portions 3a and folded inward. Therefore, if the object contained in the container is smaller than the finger insertion part 4, it is possible to keep the lid 3 fitted to the top opening of the container body 2 and fold the remaining part 6 inwards. It can be taken out from the finger insertion part 4 as a guide. In addition, when resealing the lid 3 after removing it, bend the inward folded remaining portion 6 outward and return it to its original position, and fit the lid 3 into the top opening of the container body 2. The notch 4 can be closed with the attached remaining part 6. As a result, the contents can be prevented from spilling out of the container 1 through the notch 4. Furthermore, it is possible to confirm whether the package has been opened or not by checking the presence or absence of the part surrounded by the break line.
