Then, after putting the contents in the container body (1) to which the lower lid (3) is attached,
If the upper lid (2) and the lower lid (3) are attached to the lid, the upper lid (2)
And a sealing groove provided in the lower lid (3) sandwiches the annularly shaped sealing curl portion (6) of the container body (1), and a retaining hook recessed inside the upper lid (2) for closing. (4) and the holding hook projection (5) for closing the lid provided at one end of the lower lid (3) are hooked, and the closed lid closed state is maintained.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a multipurpose closed container without a packing, in which the container body is used instead of the sealing packing.

[0002]

[Prior Art]

 In the conventional closed container of this type, both the upper lid and the main body are made of plastic or metal, and a rubber packing or a resin sealing material is used at a closed place for sealing a solid liquid or the like.

[0003]

[Problems to be solved by the device]

 This had the following drawbacks. (A) The sealing packing was always used for the sealed container. (B) In order to reduce the price of airtight containers, it is necessary to make the container body and the top lid lighter and thinner, and also make the sealing packing lighter and thinner.To this end, unless the sealing groove is provided on the top lid or the container body. However, as the packing is made lighter and thinner, the accuracy of the closed container is required, and the mold and the manufacturing machine are complicated and expensive. (C) Usually, this type of container is manufactured by using a mold or the like. Therefore, when manufacturing closed containers having different capacities, it was necessary to prepare many kinds of expensive molds. The present proposal has been made to eliminate these drawbacks.

[0004]

[Means for Solving the Problems]

 A sealing curl portion (6) is provided at one end of the container body (1) which is integrated with the bottom plate (7). Then, a sealing groove for sandwiching the sealing curl portion (6) of the container body (1) is provided at one end of the upper lid (2) and the lower lid (3). Inside the upper lid (2), a retaining hook concave portion (4) for closing the lid is provided, and at one end of the lower lid (3), a retaining hook convex portion (5) for attaching the lid is provided. It is a multipurpose closed container that does not use the packing having the above configuration.

[0005]

[Action]

 After putting an object to be housed in a closed container composed of the container body (1) and the lower lid (3) combined with each other, the upper lid (2) and the lower lid (3) are closed and attached.

[0006]

【Example】

 Hereinafter, examples of the present invention will be described. (A) A molded lower lid (3) is attached to a cylindrical container body (1) having a bottom plate (7) of the container body which is integrated with a curl portion for sealing (6) whose one end is formed into an annular shape. Insert and heat weld or apply adhesive to integrate. (B) The sealing groove formed when the upper lid (2) and the lower lid (3) are mounted with the lid is pressure-sealed with the curling portion (6) for sealing which is formed in a circular shape. The present invention is configured as described above, and when using this, after putting the contents in the container body (1) to which the lower lid (3) is attached, the upper lid (2) and the lower lid (3) are closed. When the lid is attached, the sealing groove provided in the upper lid (2) and the lower lid (3) sandwiches the curl portion (6) of the container body (1), and the lid is provided inside the upper lid (2) when the lid is closed. The holding hook concave portion (4) and the holding hook convex portion (5) provided at one end of the lower lid (3) when the lid is closed are hooked to maintain the closed lid closed state. Further, according to the present invention, the shape of the container main body (1) is a cylindrical shape, a conical shape, a square tube shape, or a square cone shape, and its material is paper, resin-coated waterproof paper, and plastics. By doing so, it becomes possible to manufacture closed containers from small volumes to large volumes by freely changing the length of the container body (1), and prepare various types of expensive molds. The need is gone.

[0007]

[Effect of the device]

 The structure is such that the lid can be easily closed and it is practically impossible to open the lid after the lid is closed. As a result, it is no longer necessary to consider the safety management of infectious medical waste and general industrial waste, and once closed, all infections can be prevented until the incineration process, and safe and reliable sterilization can be achieved. Also, if the closed container body is cone-shaped or square-cornered, it is convenient for transportation and storage. In addition, if leftover food is stored in a closed container and the lid is closed, it is possible to prevent scattering of stored items caused by dogs and cats often seen on the street corners.
