Embodiment Construction

[0046] First, a sealed cartridge according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 4 .

[0047] As shown in FIGS. 1A and 1B, a sealed box 10 according to a first embodiment of the present invention includes: a cylindrical main body part 12; a first cover part 14, which is fixed at one end part or a first end part of the main body part 12 and closes the opening a second cover 16 fixed to the other or second end portion of the main body 12 and close the opening; and a tongue or extractor 18 disposed in the main body 12 and exposed to the outside.

[0048] As shown in detail in FIG. 2A, the body member 12 is made cylindrical by overlapping two end portions in the longitudinal direction (along the central longitudinal axis A) of the sealing or airtight sheet or motherboard 12a. In this embodiment, the two end portions are not directly fixed to each other at their overlapping portion 12b (FIG. 1A), but they could also be directl...

Abstract

The sealed box includes a main columnar body, and the main columnar body includes overlapping part of the inner end part and the outer end part. The inner end part and the outer end part are separated in the direction perpendicular to the sheet with vertical shaft and horizontal shaft. Each of the first and the second end parts, which are separated in the horizontal shaft direction, has opening. The said overlapped part has a fixed area to fix the inner end part and the outer end part. The first and the second cover parts made of sheet material are fixed to the first and the second opened end parts of the main body to close the opening of the opened end parts.

Description

technical field [0001] The present invention relates to a sealed box, and more particularly to a sealed box comprising a cylindrical body member having an open end portion, a first cover closing an open end portion of the body member, and closing the A second cover member at the other open end portion of the main member. Background technique [0002] Generally, the airtight box of the above-mentioned structure can be made of a thick paper master board with a predetermined shape, for example. The motherboard should be as thin as possible in order to reduce the manufacturing costs of such sealed boxes. However, using a thin motherboard involves stiffness issues and limits its usefulness. Contents of the invention [0003] It is an object of the present invention to provide a sealed box of excellent rigidity made from a relatively thin sheet or motherboard. [0004] In order to achieve the above object, an aspect of the present invention relates to a sealed box comprising ...
