FIG. 7 is a transverse cross-sectional view showing an enlarged cross-section together with the sealing tape and the protruding portion of the first lid member adjacent to the overlapping portion.

As best shown in FIGS. 1A and 1B, a sealed container 1 according to an embodiment of the present invention.
Reference numeral 0 denotes a tubular body member 12, a first lid member 14 fixed to one opening end portion of the body member 12 to close the one opening, and fixed to the other opening end portion of the body member 12. A second lid member 16 for closing the other opening, and a handle member 18 provided on the body member 12 and exposed to the outside.
And are equipped with.

More specifically, the body member 12 is formed by overlapping both side edges of a thin plate-like material 12a having a sealing property as shown in detail in FIG. (A) has a cylindrical shape as shown. In this embodiment, the both side edges are overlapped with each other 12b.
In the above, they are indirectly fixed to each other, but they can also be directly fixed to each other. The mutual indirect fixing of both side edges of the thin plate-shaped material 12a at the overlapping portion 12b will be described later in detail in this specification.

In this embodiment, the body member 12 has a rectangular tubular cross section, but it may have a triangular shape, a polygonal shape with more than a square shape, or a perfect circular shape or an elliptical shape.

In this embodiment, the handle member 18 is the overlapping portion 12b of the material 12a of the body member 12 on both side edges.
Is formed integrally with the outer side edge portion 12a-1 located outwardly in the outer side edge portion 12a-1, and the material is formed from the central portion in the direction along the longitudinal center line of the body member 12 at the outer side edge portion 12a-1. It projects along the outer surface of the inner side edge part 12a-2 located inward in the overlapping part 12b of the both side edge parts of 12a.

The width of the tip of the handle member 18 in the direction along the longitudinal centerline is such that it can be pinched by a human finger. Both end edges 18a of the handle member 18 in the direction along the longitudinal centerline gradually move toward the longitudinal centerline from the tip of the handle member 18 toward the outer side edge 12a-1 of the material 12a of the body member 12. It is constituted by a relatively large curved surface that expands outwardly in each direction along the direction.

Such a curved surface is the material 1 of the body member 12.
In order to release the indirect or direct fixation between the overlapping portions 12b on both side edges of 2a, when the handle member 18 is picked up and an external force is applied to the handle member 18 to pull it, the outside of the material 12a of the body member 12 is removed. Both end edges 18a of the handle member 18 and the outer side edge portion 12 which are narrower than the side edge portion 12a-1.
It is prevented that the external force applied to the handle member 18 is concentrated on the boundary with a-1 and at least one of the both end edges 18a is broken.

If the external force applied to the handle member 18 is not concentrated at the boundary with -1 and at least one of the both end edges 18a is not torn, the outer side edge portion 12a-1 of the material 12a of the body member 12 is -1. On the other hand, it can be integrally formed with the outer side edge portion 12a-1 at any position along the longitudinal center line, and the shape and size of both end edges 18a of the handle member 18 can be freely adjusted. I can.

Further, if the handle member 18 can function similarly to the handle member 18 formed integrally with the outer side edge portion 12a-1 of the material 12a of the body member 12, the handle member 18 can be the material 12a of the body member 12.

Although it faces the inner peripheral surface of the portion 12a-1, it can be fixed to the inner peripheral surface of the outer side edge portion 12a-1. This means that the inner side edge 12a-2 and the outer side edge 12a-1 are indirectly fixed via the sealing tape 20 at the overlapping portions 12b on both side edges of the material 12a of the body member 12. Means that

At the time of releasing the fixing at the overlapping portions 12b of both side edges of the body member 12 using the handle member 18, the inner peripheral surface of the outer side edge portion 12a-1 of the material 12a of the body member 12 is sealed. In order that the fixing of the tape 20 to the outer surface adjacent to the outer surface can be released more easily, the outer surface of the outer tape adjacent to the outer surface of the sealing tape 20 or the overlapping portion of the both side edges of the material 12a of the body member 12 is overlapped. The inner surface of the outer side edge portion 12a-1 located on the outer side in 12b can be subjected to a fixing strength adjusting treatment for adjusting the fixing strength to a desired strength. When the fixing is performed by heat sealing, the fixing strength adjusting process is a heat sealing strength adjusting process.

The above-mentioned both side edges of the material 12a of the body member 12 can also be directly fixed to each other at the overlapping portion 12b by various known fixing means which do not impair the hermeticity of the material 12a.

When the both side edges of the material 12a are directly fixed to each other by the various known fixing means, for example, heat sealing can be performed, but depending on the degree of sealing required for the hermetically sealed container 10. Can also be done with an adhesive. Further, the direct fixing can be continued over the entire width along the longitudinal centerline in the overlapping portion 12b of the material 12a of the body member 12, and the degree of sealing required for the sealed container 10 In some cases, it may be discontinuous along the longitudinal centerline. Further, the above-mentioned direct fixing is indicated by a dotted line 1 in FIG.
As in the case of the above-mentioned indirect fixing as shown by 2c, the portion 12c-1 corresponding to the handle member 18 in the direction along the longitudinal center line is the handle member 18.
Can be closer to the tip of the handle member 18 than the portion not corresponding to.

As a result, the pulling force applied to the handle member 18 corresponds to the handle member 18 in the above-mentioned fixing of the sealing tape 20 shown by the dotted line 12c in FIG. 1 (A). A portion 12 closer to the tip of the handle member 18 than a portion not corresponding to 18
By concentrating on a portion such as C-1 that is close to the tip of the handle member 18, and continuing to apply a pulling force to the handle member 18, the portions on both sides of the handle member 18 that are close to the tip are fixed. You can easily proceed to release the fixing to the part.

Further, in the case where the material 12a of the body member 12 is directly fixed to each other at the overlapping portions 12b on both side edge portions, a fixing strength adjusting process for adjusting the fixing strength to a desired strength is performed. Can be.

When the fixing is performed by heat sealing, a heat seal fixing strength adjusting process for adjusting the fixing strength by heat sealing to a desired strength can be performed.

In any case, by gripping the handle member 18 and applying a pulling force to the handle member 18, the outer side edge portion of the body member 12 at the overlapping portion 12b of the material 12a with respect to the inner side edge portion 12a-2. In addition to the above-described indirect fixing of 12a-1, the outer side edge 12a-1 is mutually fixed to the inner side edge 12a-2 by various known fixing means that does not impair the sealing performance of the material 12a. Even if it is directly fixed to the fixing member, the fixing strength can be always adjusted to a desired strength by making it releasable and performing the fixing strength adjusting process on the fixing member.

According to the idea of the present invention, the inner side edge portion 12a-2 of the overlapping portion 12b of the both side edge portions of the body member 12 is formed.
The outer side edge portion 12a-1 is fixed to the outer side edge portion 12a-1 by indirect fixing via the sealing tape 20 as described above, direct fixing not via the sealing tape 20 as described above, or the indirect fixing and the above-mentioned fixing.
