Description

[Detailed description of the invention] This invention relates to an airtight container for containing powdered substances such as polishing powder, powdered soap, and powdered milk, as well as sweets, etc., and its purpose is to provide an airtight container that is easy to open. It's about doing.

In the airtight container according to this invention, a plastic lid is attached to the top opening of the bottomed cylindrical container body, and the lid opens upward at the boundary between the fixed part to the peripheral wall of the container body and the fixed part. and an opening/closing part connected to a fixed part that is forcibly fitted to the top opening of the container body, and a roughly U-shaped opening opening is attached to the peripheral wall of the container body from its upper end at a position corresponding to the opening/closing part. A break line for forming the finger insertion part is formed,
A tongue piece for pushing out the break line that is connected to a position corresponding to the part where the break line for forming the opening finger insertion part is formed on the edge of the opening/closing part and is approximately the same size as the area surrounded by the break line or slightly smaller. A tongue piece is attached to the outer surface of the area surrounded by the break line.

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 size of the opening/closing part in the lid can be changed as appropriate depending on the contents. As the break line, a perforation, a cut groove, a broken line cut groove, etc. are used, and the type of break line to be used is determined by taking into consideration the type, properties, etc. of the contents.

Since the sealed container according to this invention is constructed as described above, its opening is performed as follows. That is, first, strongly press the break line pushing tongue piece from the outside. Then, depending on the periphery of the tongue,
The part surrounded by the break line and close to the break line is strongly pushed inward, and the finger insertion part is formed by easily tearing at the break line without deforming the peripheral wall. This can then be done by inserting a finger into the finger insertion part and pulling the opening/closing part of the lid upward to remove the forcible fitting of the opening/closing part, and then opening the opening/closing part upward. Therefore, opening becomes easy, and there is no need to provide an opening handle on the lid or prepare a separate opening tool. Moreover,
The shape of the lid can be made simple and clear. Further, even after opening, the opening/closing part can be closed and forcibly fitted into the top opening to re-seal the bag. Furthermore, it is possible to confirm whether the package is sealed or unopened by checking the presence or absence of the part surrounded by the break line.

This invention will be explained below with reference to the drawings. In the following description, the terms "front and back" refer to FIG. 2, the "front" refers to the left side in FIG. 2, and the "back" refers to the right side in FIG. 2. In addition, left and right mean toward the rear.

The airtight container 1 has a rectangular plastic lid 3 attached to the top opening of a bottomed prismatic cylindrical container body 2.

A substantially U-shaped breaking line 4 for forming an opening finger insertion part is provided at the center of the upper edge of the front wall 2a of the container body 2 in the left-right direction. This breaking line 4 consists of a perforation. A crease groove 5 extending in the left-right direction is provided in the center of the top surface of the lid 3 in the front-rear direction. A hanging wall 6 is provided at a portion slightly inside the periphery of the lower surface of the lid 3 over the entire circumference. hanging part 6
The portion in front of the crease groove 5 is formed to be lower in height than the portion in the rear. In addition, a notch 7 is made from the lower edge in the center of the left and right sides of the hanging wall 6 in the front-rear direction, and the fold groove 5 and the notch 7 allow the lid 3 to move upward around the fold groove 5. It is designed to be folded in two. The lid 3 is forcibly fitted into the top opening of the container body 2 such that the hanging wall 6 is in close contact with the inner surface of the peripheral wall of the container body 2, and the portion of the hanging wall 6 on the rear side of the notch 7 is connected to the inner surface of the container body 2. It is bonded to the rear parts of the left and right side walls 2b and the inner surface of the rear wall 2c of the peripheral wall with an adhesive. A portion of the lid 3 on the rear side of the crease groove 5 and the notch 7 serves as a fixing portion 3a to the container body 2, and a portion on the front side serves as an opening/closing portion 3b. A tongue piece 8 for pushing the break line, which is approximately the same size as the area surrounded by the break line 4, is provided in a hanging manner in a continuous manner at the center of the front edge of the opening/closing part 3b in the left and right direction. It is pasted on the outer surface of the area surrounded by 4.

The method for opening this airtight container 1 is shown in Figures 3 and 4.
This will be explained with reference to the figures. First, as shown in FIG. 3, press the tongue piece 8 strongly with your fingers from the outside to the inside.
Then, a portion of the peripheral edge of the tongue piece 8 surrounded by the break line 4 and close to the break line 4 is strongly pushed inward, and the break line 4 is easily broken. In this way, the finger insertion portion 9 consisting of a U-shaped notch is formed by breaking the portion surrounded by the breaking line 4. When the finger insertion part 9 is formed, the front wall 2a of the container main body 2 opens slightly in the left-right direction, so that the opening/closing part 3b can be easily removed from the opening of the container main body 2. Next, insert a finger into the finger insertion part 9 and open the opening/closing part 3b upward. The broken part 10 surrounded by the breaking line 4 remains adhered to the tongue piece 8. After dispensing the required amount of contents in the container body 2, the opening/closing portion 3b is closed and fitted into the portion of the top opening of the container body 2 in front of the fixing portion 3a. At this time, the finger insertion part 9
is closed by the fracture portion 10.

FIG. 5 shows a modification of the method of attaching the lid 3 to the top opening of the container body 2.

In FIG. 5, the upper edge of the peripheral wall of the container body 2 is
A folded portion 11 is formed by folding inward and extending over the entire circumference. Furthermore, an outwardly projecting edge 12 is provided at the lower edge of the hanging wall 6 in the fixing portion 3a of the lid 3. The fixing part 3a is fixed to the container body 2 by the outwardly protruding edge 12 engaging with the folded part 11.

Modifications of the breaking line are shown in FIGS. 6 to 8.

Break line 24 shown in FIGS. 6 and 7
is provided to form a substantially hexagonal notch continuous to the upper edge of the front wall 2a of the container body 2, and is formed by one cut groove having a V-shaped cross section. The break line 24 may have a cross-sectional shape as shown in FIG.
