JPS5923722Y2 - Cream container mouth sheet - Google Patents

Description

[Detailed description of the invention] The present invention uses an aluminum container or the like with its mouth closed, and the contents, especially the oil content of the W10 cream, seeps into the inner surface of the lid and leaks out of the lid. Regarding the sheet that prevents this.

The continuous phase of U-shaped creams such as skin creams is an oily component, and when this is placed in a glass container, the water component of the dispersed phase is attracted to the glass surface because glass is hydrophilic, and the cream's water component is attracted to the surface of the glass. There are issues that affect stability.

Furthermore, since containers made of synthetic resins such as styrene are lipophilic, there is a problem in that the containers may crack.

Therefore, in the case of W10 type cream, containers made of metal, especially thin plates of aluminum, which are easy to process, are mainly used without any stability problems.
Both the container and the lid have concave cross-sections, and the lid is attached to the container simply by inserting the mouth of the container into the lid.

Then, the surface of the cream placed in the container is covered with aluminum foil laminated with glassine, and the entire periphery is folded over the outer circumference of the container to seal the mouth of the container and prevent oil from leaking. is prevented.

However, aluminum foil is extremely thin because it is necessary to fold the outer edge over the outer circumference of the container, but such thin aluminum foil has many pinholes all over it. During storage through this pinhole, the oil component of the cream gradually oozes out and adheres to the inner surface of the lid.

If the amount of oil adhering to the inner surface of the lid increases, since the container and lid are only inserted into each other as mentioned above, oil will leak from the inner surface of the periphery of the lid to the outer surface of the container, which will reduce the product value. There is a problem with this.

The proposed sheet solves the above problems.

To explain the embodiment shown in the drawings, 1 is an aluminum foil that covers the entire mouth of the container for cream and has a size and shape that allows its peripheral edge to be folded over the outer surface of the peripheral wall of the container. ing.

2 is a glassine layer laminated on the outer surface of the aluminum foil 1; 3 is an oil-absorbing sheet made of filter paper or blotting paper layered on the side of the glassine layer 2; this is made to have approximately the same diameter and shape as the container; A part of it is adhered and fixed to the glassine layer 2.

4 is the adhesive part of the oil-absorbing sheet 3 to the glassine layer 2, and as long as the adhesive is attached to a small portion that does not affect the oil-absorbing ability of the oil-absorbing sheet 3, there is no need to limit the adhesive position. It is suitable to adhere the center part of the oil-absorbing sheet 3 in a linear or circular shape.

The adhesive portion 4 may be provided at one location or at multiple locations.

5 is the container, and 6 is the lid.

The structure of the sheet of the present invention is as described above, and when this is used, the aluminum foil 1 side is joined to the container 5 and placed on the mouth of the container 5.

The placed aluminum foil 1 is folded over the outer circumferential wall of the container 5 together with the glassine layer 2 which is laminated to the outer peripheral portion thereof, and the lid 6 is attached to the container 5.
The entire mouth of the container 5 is sealed with the glassine layer 2 and the glassine layer 2, and an oil-absorbing sheet 3 is interposed between the aluminum foil 1 and the earthen wall of the lid 6.

The folding of the aluminum foil 1 on the container 5 is as follows:
It is optional, for example, to do this at the same time as inserting the mouth side of the lid 6 into the lid 6.

Although the oil-absorbing sheet 3 is relatively thick, since it is adapted to the mouth of the container 5, there is no problem in putting on the lid 6.

In this way, the sheet of the present invention has an oil-absorbing sheet 3 overlaid on an aluminum foil 1, and when this is placed on the mouth of the container 5, the oil-absorbing sheet 3 is placed on the lid 6 side, and the structure of the oil-absorbing sheet 3 is porous. Filter paper or blotting paper with a rough surface and excellent oil absorption ability is used.

Therefore, even if W10 type cream is placed in the container 5 and the oil component of the cream passes through the aluminum foil 1 and the glassine layer 2 and oozes out onto the surface of the glassine layer 2 during storage, all of the oil will be removed one by one. The oil-absorbing sheet 3 absorbs the oil.

In addition, the surface of the oil-absorbing sheet 1-3 is relatively rough and prevents the flow of oil seeped onto the surface of the glassine layer 2, and absorbs the oil at that position, so that the amount of oil absorbed by the oil-absorbing sheet 3 is uneven. , and the structure of the oil-absorbing sheet 3 is porous.
Since the retention power of the absorbed oil is large and there is no risk of oil seeping out from the oil-absorbing sheet 3, the problem of the oil component of the cream leaking from the inner surface of the lid 6 to the outer circumferential surface of the container 5 and affecting the product value is solved. can.

The oil-absorbing sheet 3 will be somewhat thick, but if you glue and fix it to the glassine layer 2 at the center, you can use the cream in the container 5 with only a part of the aluminum foil 1 turned over. In this case, the oil-absorbing sheet 3 can be easily folded together with the aluminum foil 1, and there is no problem in using the cream.

Since a part of the oil-absorbing sheet 3 is fixed to the glassine layer 2 with adhesive, it is easy to place it on the mouth of the container 5.
Moreover, since most of the oil-absorbing sheet 3 only overlaps the glassine layer 2, the entire amount of oil that has passed through the aluminum foil 1 can be reliably absorbed.
