Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a container with an airtight sheet, which has a sealing sheet such as an aluminum laminate sheet attached to the rim of the container to seal the mouth of the container.

[Conventional technology]

Conventionally, this type of container with an airtight sheet was
As described in Japanese Utility Model Application Publication No. 59-112766 (Fig. 3), a plurality of thin-walled broken pieces 10 are found around the rim of the container.
A ring 6 is connected through the ring 6, a handle 11 is attached to a part of the ring 6, and a sealing sheet 7 is attached to the rim of the container and the top surface of the ring 6 to seal the container mouth 2. is known, in which the ring 6 is broken and separated from the rim of the container along the thin-walled broken piece 10 by pulling the handle 11, and at this time, the sealing sheet 7 is pulled together with the ring 6 from the rim of the container. The opening 2 of the container is opened by peeling it off.

[Problem that the invention attempts to solve]

By the way, with this structure, ring 6
The ring 6 acts as a reinforcement when the sealing sheet 7 is peeled off, preventing the sealing sheet 7 from tearing from the edge, making it easier to peel off the sealing sheet 7. In the structure in which the broken piece 10 is connected to the rim of the container, the sealing sheet 7 must be peeled off while breaking the thin broken piece 10, and no matter how easy the thin broken piece 10 is to break, the sealing sheet 7 can be removed smoothly. cannot be removed.

Further, in such a structure, once the ring 6 is removed from the container mouth edge and the sealing sheet 7 is peeled off, the container mouth portion 2 cannot be closed again. This is because this type of container contains, for example, instant noodles, coffee cream, or medicines, etc.
This is because it is intended for one-time use, and there is no inherent intention to use it again.

However, there are times when it is desirable to temporarily cover a container containing such contents.

The present invention was developed in view of these points, and its technical challenges are to enable the sealing sheet to be peeled off smoothly and to enable the sealing sheet once removed to be used again as a lid body. It is something.

[Means for solving problems]

In order to solve the above technical problem, the present invention takes the following measures.

That is, in the present invention, a ring 6 is removably fitted onto a mouthpiece 3 forming a container mouth 2, and the upper end surface of the mouthpiece 3 and the upper end surface of the ring 6 are flush with each other. Then, a sealing sheet 7 was pasted on the upper end surface of the mouth tube part 3 and the upper end surface of the ring 6 to seal the container mouth part 2 to form a container with a sealing sheet.

Here, the means for externally fitting the ring 6 onto the mouth tube portion 3 is a removable attachment means such as screwing or undercut fitting. Further, the sealing sheet 7 includes not only the aluminum laminate sheet but also other sheets and films.

[Effect]

By simply removing the ring 6 from the mouth barrel part 3 of the container, the sealing sheet 7 is peeled off from the upper edge of the mouth barrel part 3, and the container mouth part 2 opens. However, the sealing sheet 7 is
When the ring 6 is attached to the mouth tube part 3, the container mouth part 2 is closed by the sealing sheet 7.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG.

The container of this embodiment is to contain powdered anti-inflammatory agent for one-time use, and the container main body 1, which has an open top, is large enough to be pinched with one's fingers, and is inserted from the bottom of the lower end to the opening 2 of the upper end. It is shaped like a latch, with the diameter increasing as you go, making it easy to pick up.

The container mouth part 2 is formed of a short mouth part 3, and a flange part 4 is provided around the base of the mouth part 3. A male thread 5 is provided on the outer periphery of the mouth barrel portion 3.
A ring 6 is removably screwed onto this male thread 5.

When this ring 6 is screwed onto the mouth barrel part 3, its upper end surface is at the same height as the upper end surface of the mouth barrel part 3, and ultrasonic waves are applied to the upper end surface of these rings 6 and the upper end surface of the mouth barrel part 3. An aluminum laminate sheet, that is, a sealing sheet 7 is pasted to the container opening 2 by means of a seal or the like.
is blocked.

The procedure for attaching the sealing sheet 7 to the upper end surface of the ring 6 and the upper end surface of the mouth tube part 3 is to screw the ring 6 onto the mouth tube part 3, and then attach the sealing sheet 7 to the upper end surfaces of each at the same time. You can paste it, or
Before the ring 6 is screwed on, the sealing sheet 7 may be attached to the upper end surface of the ring 6 in advance, and then the ring 6 may be screwed together with the sealing sheet 7 to the mouth tube part 3, and the ring 6 may be attached to the upper end surface of the mouth tube section 3. .

In order to peel off the sealing sheet 7 and open the container opening 2, it is sufficient to simply turn the ring 6 and remove the screw fitting. In this way, the sealing sheet 7 is peeled off only from the upper end surface of the mouth tube part 3 while remaining attached to the upper end surface of the ring 6, and the container mouth part 2 is opened.

Therefore, if it is desired to close the container mouth 2 again with the sealing sheet 7, the ring 6 can be screwed onto the mouth barrel part 3 again.

Note that the means for attaching the ring 6 to the mouth tube 3 does not have to be screwed; as shown in FIG. 2, an annular projection 8 is provided around the mouth tube 3 by a so-called undercut, and An annular recess 9 may be formed on the inner circumferential surface of the ring 6, and the ring 6 may be fitted into the mouth tube portion 3 by fitting the annular protrusion 8 and the annular recess 9.

[Effect of idea]

According to the present invention, with the above configuration,
The sealing sheet 7 can be removed by simply removing the ring 6 from the mouth tube part 3.
The container mouth part 2 can be opened by peeling it off from the upper end surface of the mouth barrel part 3, and the work of peeling off the sealing sheet 7 can be done smoothly and easily.

Further, even after the sealing sheet 7 is peeled off, the sealing sheet 7 remains attached to the upper end surface of the ring 6, so simply attaching the ring 6 to the mouth tube part 3 closes off the container mouth part 2 again with the sealing sheet 7. be able to.
