[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a moisture-proof container and provides a moisture-proof container widely used for long-term storage or medium-term storage of contents requiring moisture-proof properties.

[0002]

2. Description of the Related Art As is well known, containers filled with pharmaceuticals, beverages, chemicals, and other industrial materials that are required to be moisture-proof are mainly made of glass or synthetic resin.
Depending on the shape of the object to be stored (powder, granule, tablet, liquid, etc.) and its use and handling method, there is a difference in the size of the container body, or the shape such as circular or square, but the mouth part is It is formed in a generally cylindrical shape, and after filling an object to be stored, a cylindrical clip-off cap or a cylindrical screw cap having substantially the same diameter as the outer diameter of the cylindrical mouth is fitted.

[0003] Recently, when the cylindrical clip-off cap or the cylindrical screw cap is fitted, an inner seal material (typically, a laminar packing of a disk-shaped packing and a disk-shaped aluminum membrane with a low adhesive force) is used. A commercially available product such as "Pashut" (trade name: manufactured by Hi-Sheet Industry Co., Ltd.) is used, and the packing surface of the inner seal material is loaded toward the inner bottom surface of the cap. A mode is adopted in which the aluminum membrane surface is fitted to a container having a mouth and heated by high frequency with a high frequency sealer so that the aluminum membrane surface is adhered to the mouth and sealed.

[0004]

In the conventional product sealed in the above-described manner, when the container is opened to take out the contents, the clip-off cap is pushed up or
Alternatively, by loosening and removing the screw cap, the packing easily peels off from the aluminum membrane and remains in the cap, but the membrane is firmly adhered to the opening edge of the container opening by high frequency heating performed in advance. Not only that, the diameter is formed almost the same as the outer diameter of the mouth, so that there is almost no margin for grasping by a human finger, so that there is a problem that it is not easy to peel off this. Also, even if it is unavoidable to scrape with a knife etc., if the residue of the membrane is not completely removed, take out a part of the stored object, re-fit the cap, and remove the packing remaining in the cap into a container. Even if it reseals against the opening edge of the mouth, the outside air flows into the container from the slight gap formed by the residue adhering to the mouth, and the moisture resistance is impaired. There is a problem that the contents may be altered or rot, etc., and furthermore, a small piece of the membrane rubbed with a knife or the like may be mixed into the contents and adversely affect the human body at a later date. There is probably sex.

[0005]

The above problems can be solved by the present invention as follows. That is, according to the present invention, the disc-shaped packing 2 and the disc-shaped aluminum membrane 3 are attached to the container A having the cylindrical opening 41 filled with the contents required to be moisture-proof with low adhesive strength. The laminated inner seal material is fitted with a cylindrical cap which is loaded with the packing 2 surface facing the inner bottom surface of the cap 1 , and the high-frequency sealer is used to cover the aluminum membrane 3 surface with the thick opening edge of the opening 41.
43 , the mouth part 4
A moisture-proof container characterized in that a part of one thick opening edge 43 is formed in a substantially linear shape 44 .

[0006] The present invention, will be described in detail by taking an example moisture resistant container A dated clip off the cap, in FIG. 1 shows a longitudinal section of the container A, there is no conventional products in a cylindrical mouth portion 41 of the container A major feature is that the gripping portion 5 is newly formed, and its plane is in the form shown in FIG.
is there. That is, the thickness of the opening 41 of the container A formed of concentric circles is increased.
Lacks shaped gripping margin portion 5 cut in the container A is formed by changing a part amount of the rim 43 to the linear portion 44. Thus, as can be seen from Figure 1, the thickness opening edge of the mouth 41 43
A gripping margin 31 is formed on a part of the disk-shaped aluminum membrane 3 adhered to the aluminum foil. If the gripping margin 31 is grasped with a finger and lifted, the peeling is performed extremely smoothly. Note that the range of the linear portion 44 should be within a central angle of 90 ° or less, preferably 60 to 30 °. If the linear portion is too long, sealing performance will be affected.

[0007]

The thick opening edge 43 of the cylindrical mouth portion 41 of the container A is
It has a linear portion 44 in a part thereof , but since the portion other than the linear portion 44 is formed in a substantially perfect circle, the packing having the same diameter as the outer diameter of the thick opening edge 43 after storing the contents in the container A is described. The clip-off cap 1 in which an inner sealing material, which is a composite of an aluminum membrane 3 and an aluminum membrane 3 with low adhesive strength, is loaded with the packing surface facing the inner bottom surface of the cap, is inserted into the opening 4 of the container.
1. The aluminum membrane 3 can be hermetically sealed by being pressed into and fitted with the surface of the aluminum membrane 3 using a high frequency sealer. When opening, the lower end of the outer peripheral edge of the clip-off cap 1 is pushed up with a finger and removed, and the packing 2 is removed together with the cap 1 and only the aluminum membrane 3 is opened.
Since There remains in a state of being adhered to the wall thickness opening edge 43, by raising the tensile picking gripping margin 31 of this with a finger, simply aluminum member Buremu 3 is peeled off from the thick opening edge 43, the accommodated article If the clip-off cap 1 is pushed into the mouth portion 41 and fitted again, the packing 2 in the cap 1 comes into pressure contact with the thick opening edge 43 of the mouth portion 41, so that resealing can be performed.
