BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary tool used for opening a container by rotating a lid screwed to the mouth of the container.

[0002]

2. Description of the Related Art Containers for foods are generally made of glass,
Bottles made of synthetic resin are used. In such a container, a lid is often screwed to a screw portion provided at the mouth, and can be opened and closed by rotating the lid along the mouth. The lid body is provided with unevenness so that the lid body can be easily grasped and friction between the hand and the lid body is increased, and when the container having the lid body is opened and closed, the container body is opened. Hold with one hand, grasp the lid with the other hand, and rotate the lid along the mouth.

However, the container tends to be tightly sealed at the time of shipping in order to avoid deterioration of the contents, and especially when the container is first opened after purchase, the lid is fixed to the container and is difficult to open. Also, even after opening once, the gas enclosed in the container contracts, or the contents attached to the lid solidify, and the lid sticks to the screw part of the container and becomes difficult to open. There is.

Therefore, for example, a rubber sheet is used as an auxiliary tool for allowing the lid body to be easily rotated without slipping the gripping hand.

The rubber sheet itself is a material having a large friction on the sheet surface. Such a rubber sheet is put on the lid of the container, grasped by hand from above the sheet, compressed using rubber elasticity, and bites into the unevenness provided on the lid surface, The friction between the lid and the surface in contact with the lid is increased to facilitate rotation of the lid. In order to make the above effect effective, the rubber sheet is preferably thick.

However, if the rubber sheet is thick, it becomes difficult to conform the shape of the lid body to the sheet when the sheet is put on the lid body of the container as described above, and it is difficult to grasp by hand from above the sheet. There is an inconvenience. Further, when the rubber sheet is made thin, the tear strength is lowered and it becomes easy to tear.

On the other hand, it is possible to increase the frictional engagement force of the surface of the sheet-shaped body that abuts the lid by forming the slow-drying adhesive layer on the surface of the thin sheet-shaped body. Examples of the thin sheet-shaped body in this case include a sheet made of rubber or synthetic resin, a woven fabric, a non-woven fabric, and the like.

However, in the case of a rubber or synthetic resin sheet, the smoothness of the surface is so high that the adhesive layer formed by coating may be easily peeled off, and the peeled adhesive may be transferred to the lid of the container. On the other hand, in the case of woven cloth, non-woven cloth, etc., the adhesive material is absorbed by the fibers, and it is difficult to form the adhesive material layer on the surface of the cloth.

[0009]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a container opening assisting tool which solves the above inconvenience and can easily rotate the lid of a container which is difficult to open.

[0010]

In order to achieve the above object, the container opening assisting tool of the present invention is used for opening a container by rotating a lid screwed to the mouth of the container. A container opening aid, characterized in that a slow-drying adhesive layer is provided on the flesh surface of the leather, and the surface provided with the adhesive layer is brought into contact with the lid.

The container opening aid of the present invention uses leather as a material. Since leather is a material that is thin and flexible and has excellent tear strength, it is suitable for the purpose of grasping it from above along the shape of the lid. In addition, leather is made by tanning the raw hide peeled from the carcass and removing the epidermis and subcutaneous tissue, and is composed only of the dermis, and its surface is fixed with fibers and tissues made of collagen, which is the main protein of the skin, Since it is stabilized, it is difficult for liquid substances to be absorbed.

The term "flesh surface" is a term that refers to the surface of the leather surface on the side where the collagen fiber bundles (fibers) are exposed to form a rough surface. On the other hand, the surface of the leather on the epidermis side is called the “silver surface”, and the fine fibers of collagen (fibrils) do not form fibers and run as they are and are entangled with each other, so they are smooth, It is used on the front side of ordinary leather products such as leather crafts.

In the present invention, for example, cowhide, pigskin, sheepskin or the like is used as the leather. Among the leathers, thick leather such as cowhide is divided into two or three layers (sliced) to be processed into leather products. At this time, the layer closest to the epidermis has a silver surface, and the back is a flesh surface. In addition, the lower layer part is called floor leather, and both sides are flesh.

In the present invention, in the case of leather with a silver surface, the adhesive layer may be formed on the back meat side, but when using floor leather, the adhesive layer can be formed on either side. Therefore, it is advantageous. Further, since the both sides of the floor leather are rough, the application is limited as compared with the side having the silver surface, and it is advantageous in that it can be obtained at low cost.

The slow-drying adhesive material is hard to dry and solidify,
A natural rubber-based adhesive material is preferable because the adhesive force can be maintained for a long period of time. The natural rubber-based pressure-sensitive adhesive is a solution or dispersion of natural rubber in an organic solvent, and may include synthetic resin in addition to natural rubber, and the organic solvent has a high boiling point in order to enhance the effect of making it difficult to dry and solidify. It is preferable to contain the aliphatic compound of.

The adhesive material is made of natural rubber having a solid content of 10 to 10.
A liquid containing about 15% by weight and having a viscosity of about 13,000 to 17,000 cps at 30 ° C. measured by a BM type viscometer is suitable.

[0017]

According to the container opening assisting tool of the present invention, since the slow-drying adhesive layer is provided on the surface that contacts the lid, the assisting tool can be grasped by hand from above the assisting tool. A large frictional engagement force is obtained between the lid and the lid, and the lid is easily rotated.

Since the container opening aid of the present invention is made of thin and flexible leather having excellent tear strength, it can be grasped according to the shape of the lid when it is wrapped. It will be easier.

Further, since the slow-drying pressure-sensitive adhesive layer is formed on the flesh surface of tanned leather, it is difficult to be absorbed,
Collagen fibers exposed on the surface of the flesh are taken into the adhesive material layer, which makes peeling difficult.

By using a cowhide floor leather as the leather, a slow-drying adhesive layer can be provided on either side of the leather, which facilitates production. Further, cowhide floor leather can be obtained at low cost, so that the manufacturing cost can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The container opening assisting tool of the present invention will now be described in more detail with reference to the accompanying drawings. FIG. 1 is an explanatory cross-sectional view showing the structure of the container opening aid of this embodiment, FIG. 2 is a cross-sectional view schematically showing the structure and processing method of cowhide, and FIG. 3 is the use of the container opening aid of this embodiment. It is a perspective view showing a method.

In the container opening assisting tool 1 of this embodiment, as shown in FIG. 1, an adhesive layer 3 made of a natural rubber adhesive is applied and formed on one surface of a cowhide floor leather 2.

As shown in FIG. 2, the animal skin generally comprises a dermis 4 and an epidermis 5, and the dermis 4 is in contact with the subcutaneous tissue 6 inside. The dermis 4 is a portion that is processed into leather through a tanning process, and is composed of a mesh layer 8 in which fibrils of collagen form fibers 7, and a hair root 9, a papilla layer 11 having sweat glands 10, and the like.

When processing animal hides into leather, first, a blade is inserted into the subcutaneous tissue 6 to peel off the portion above the subcutaneous tissue 6 from the carcass, and then the remaining subcutaneous tissue 6 and the epidermis 5 are removed. Next, by tanning and processing the dermis 4, the leather 1
2 is obtained.

At this time, the surface of the leather 12 on the surface 5 side is
The fibrils of collagen run as they are without forming the fibers 7 and are entangled with each other, and the roots 9 are closed by the tanning process to form a smooth silver surface 13. On the other hand, the surface of the dermis 4 on the side of the subcutaneous tissue 6 is a rough surface where the fibers 7 are exposed even after the tanning process and becomes a meat surface 14.

In the case of cowhide, since the obtained leather 12 is thick, it is usually divided into 2 to 3 layers (sliced),
It is divided into a leather 15 with a silver surface 13 and a floor leather 2 without a silver surface 13. Since the division is performed by inserting a blade into the mesh layer 8 and tearing it thinly, the floor leather 2
Has a flesh surface 14 with the fiber 7 exposed on both sides.

The silver-coated leather 15 is used as a raw material for various leather products by making the smooth and beautiful silver surface 13 face up.
Since the floor leather 2 has both surfaces 14 and a rough surface, its use is limited and it can be obtained at low cost.

In this embodiment, as an adhesive material forming the adhesive layer 3, 11% by weight of natural rubber (solid content) and 1% by weight of synthetic resin (solid content) were dissolved in 88% by weight of an organic solvent. I used a natural rubber adhesive. The adhesive is
The viscosity measured at 30 ° C using a BM type viscometer is 130.
The range was from 00 to 17,000 cps. The organic solvent contains toluene and hexane as main components and contains a trace amount of high-boiling point aliphatic carbon.

When the adhesive material is applied to the surface of the floor leather 2,
Low-boiling components such as toluene and hexane in the organic solvent are volatilized to form the slow-drying adhesive layer 3 composed of natural rubber, synthetic resin, and a small amount of high-boiling aliphatic carbon. Since both sides of the floor leather 2 have the meat surface 14, the adhesive layer 3 may be formed on either side.

In this example, the slow-drying adhesive layer 3 having a dry thickness of 0.1 mm was formed on the meat surface 14 of the floor leather 2 having a thickness of 1 mm as described above. Container opening aid 1 of the present embodiment
Since the adhesive material layer 3 is formed on one surface of the floor leather 2 as described above, the fibers 7 exposed on the flesh surface 14 are taken into the adhesive material layer 3 and the adhesive material layer 3 is applied to the floor. It is difficult to peel from leather 2. Next, a method of using the container opening aid 1 of this embodiment will be described.

First, as shown in FIG. 3, the container opening assisting tool 1 is covered from above the lid 32 screwed to the mouth of the container 31 so that the adhesive layer 3 contacts the lid 32. To do.

Next, the lid 32 is grasped by hand from above the container opening assisting tool 1. The container opening assisting tool 1 conforms to the shape of the lid 32 by being held down by hand, and the adhesive material layer 3 adheres to the surface of the lid 32. At this time, the container opening aid 1
Since the floor leather 2 having the above thickness is used as a material, it is thin and flexible and easily conforms to the shape of the lid 32.

On the other hand, the lid 32 has a screw portion 33 corresponding to the screw portion formed at the mouth portion of the container 31 and the slip stopper 3.
Unevenness such as 4 is formed. Therefore, by the above operation, the adhesive material layer 3 bites into the unevenness of the screw portion 33, the slip stopper 34, etc., and further adheres strongly.

By performing the opening operation of the container 31 in the above-described state, a large frictional engagement force can be obtained between the container opening assisting tool 1 and the lid 32, so that the lid 32 can be easily rotated. Therefore, the container 31 can be easily opened. In the opening operation, a considerable grasping force and a frictional force act in the direction of tearing the container opening aid 1,
Since the container opening assisting tool 1 is made of the floor leather 2, the container opening assisting tool 1 has excellent tear strength and is not easily broken. Further, since the adhesive layer 3 is formed by taking in the fibers 7 exposed on the flesh surface 14 as described above, it is difficult to peel from the floor leather 2 and does not transfer to the lid 32 before and after use. .

In the container opening aid 1 of this embodiment, it is preferable that a film of vinyl chloride or the like is attached to the surface of the adhesive layer 3 when not in use. By doing so, it is possible to protect the adhesive layer 3 and prevent it from adhering to unnecessary portions.

In this embodiment, the floor leather 2 is used as the material of the container opening aid 1, but the leather 15 with silver is used to form the adhesive layer 3 on the meat surface 14 on the back side of the silver surface 13. It may be formed by coating.
