Description

  The present invention relates to a screw cap opening tool for facilitating opening of a cap of a screw cap such as a beverage container.

  Normally, when opening a beverage container with a screw lid at a place where the user is going out, it is common to open the beverage container with a hand and a fingertip. However, depending on the container, the screw cap of the container is tightly closed, and for example, it is often difficult for an elderly person or a person with weak fingertips to open the container by hand. For this reason, many cap openers have already been marketed as stoppers for containers with screw caps.

  Although various types of portable ones are commercially available, many have a fixed lid size of the container to be applied, and examples of those that can be applied to the screw lids of a plurality of containers are described in Patent Document 1, for example. Such a multi-stage portable device has been filed.

However, the one described in Patent Document 1 is applied to a plurality of limited lid sizes (diameters) in a multi-stage manner, and the thickness increases as the number of lids applied increases. Although it can be carried in a clothes pocket or second back, it is difficult to store it in a wallet card holder or business card holder.
Therefore, with the spread of vending machines and the aging society, a multifunctional unit that is easy to use without bulk and easy to carry, and that can easily open multiple screw caps with different diameters with a single tool. The realization of a type of stopper was expected.

Issues that the device is trying to solve

  As described above, this device is simple to use and easy to carry, and is a multi-functional device that allows elderly people and people with weak fingertips to easily open the screw caps of containers with different diameters with a single tool. It is an object of the present invention to provide a single-type screw cap stopper.

Means to solve the problem

  In this invention, a drop-shaped through-hole is provided in a credit card-shaped plate-like substrate, and the inner wall surface of the opening is strong only on one side of the wall surface with which the screw cap comes into contact. A screw cap opening device characterized in that a friction structure surface portion is provided, and further, by bending the opening portion in a shape of a bevel, in a plate-shaped substrate having a limited area, It can be applied to the opening of screw caps of different sizes. The strong frictional structure provided on the inner wall of the opening is such that the inner wall of the opening is in contact with the outer periphery of the screw cap in a stepless manner according to the size of the screw cap and strongly sandwiches the same, thereby causing a large rotation. The feature of the main configuration is that the screw cap can be easily opened by applying a torque.

  The plate-shaped substrate of the present invention is basically based on the shape and dimensions of a credit card type, and is preferably made of a material that is as light and strong as possible. In the case of a hard material such as metal, it is preferable to use a light-chamfered edge or a thin protective member provided in the case of a hard material such as metal to be stored in a card storage section such as a wallet or a regular wallet. Note that the size and shape of the plate-like body or the size of the opening are not limited to the credit card type, but are design items that can be freely selected according to the use environment as needed.

  Furthermore, if it is applied to a screw cap having a large number of external dimensions in a limited area of the plate-shaped substrate, a drop-shaped opening becomes long. In order to effectively use the area, it is possible to solve the problem by bending the drop-shaped opening to form a magatama-shaped opening (see FIG. 2). In this case, the straight line connecting the position of the outer peripheral surface of the screw cap that comes into contact with the large curved face and the small curved face of the inner wall always precedes the center of the screw cap. By forming the curved shape so as to be in the position, that is, the small direction of the muzzle-shaped opening, the screw cap is more smoothly and accurately bitten.

  Both the drop-shaped opening and the muzzle-shaped opening of the present invention have a friction structure having a strong locking force only on one inner wall surface with which the outer peripheral surface of the screw cap contacts, for example, small saw blade-shaped irregularities. Although formed, all other outer peripheral contact surfaces are constituted by smooth surface portions without frictional structure portions. Even if the positions of the friction structure surface portion and the smooth surface portion are reversed, the effect of inserting and rotating the screw cap in a stepless manner according to the size of the screw cover does not change.However, the screw cover is reversed by reversing the position of the friction structure surface portion. The direction of rotation is also reversed.

The effect of the invention

  According to this invention, the frictional surface provided on the inner wall surface of the drop-shaped through-opening of the plate-like substrate draws in one of the contact surfaces of the screw lid that first came into contact, and slightly rotated the screw lid. As a result, the outer peripheral surface of the screw cap bites into the wall surface of the opening (this operation is hereinafter referred to as "automatic biting operation"). Therefore, if the outer edge of the plate-shaped substrate or a place near the outer edge is gripped with the fingers of the hand and turned, the distance between the center of the diameter of the screw cap and the position of the plate-shaped substrate gripped with the fingers is determined. A large rotational moment is generated based on the principle of leverage by difference. In addition, the effect of the automatic biting action is further improved by bending the drop-shaped opening to form a muzzle-shaped opening, and screws with different sizes in a plate-shaped substrate with a limited area It can be applied to opening the lid.

  The screw cap opening tool of this invention is a screw cap opening tool that can be easily carried in a small case such as a wallet or business card holder by making it into a shape and size of a credit card type. Screw caps for a wide variety of containers of different types and sizes, such as vending machine PET bottles, health foods and cosmetics, despite having only one plate-like substrate with a mold-shaped opening or a magatama-shaped opening The effect of the present invention is an excellent multifunctional single type that can be applied up to.

FIG. 1 is a plan view of a screw cap opener according to a first embodiment of the present invention, showing a basic concept of the present invention. A shows the whole screw cap stopper of this invention.
The screw cap opening / closing device of the present invention is constituted by only one credit card type plate-like substrate. Although the stainless steel substrate was used in the embodiment, for practical use, it is often carried in a commonly used card holder such as a business card holder or a wallet. It is preferable to use a material having high strength, such as a light metal or a synthetic resin, which can withstand use strength and which can be used by engraving or printing on the surface.

  The substrate 1 is provided with a penetrating opening 2 for inserting a screw cap. The opening 2 forms a drop-shaped opening, and the inner wall surface of the opening 2 has a strong friction structure surface provided only on one of the inner wall surfaces with which the outer periphery of the screw cap comes into contact. 2a and another smooth surface portion 2b without a friction structure surface are provided. According to this embodiment, the friction structure surface portion 2a is a wall surface above the opening in the drawing, and all other wall surfaces are smooth surface portions. This friction structure surface is, for example, a friction structure surface having a small saw blade shape or unevenness, and has a non-slip function of engaging with a non-slip streak pattern provided on the surface of the screw cap of a normal container. Any structural surface having a shape and size may be used.

  In addition, the size and shape of the plate-shaped substrate 1 are basically created in the shape and size of the credit card according to the international standard, but the usage environment and the user's It can be designed freely as needed. Further, in order to provide safety and good texture when carrying or operating, it is preferable to perform additional design processing such as appropriately rounding the corners of the substrate, chamfering, or providing a protective cover. Reference numeral 3 denotes an outer edge of the substrate, and reference numeral 4 denotes a mounting hole for a strap.

FIG. 2 is a plan view of a screw cap opening tool according to a second embodiment of the present invention.
This embodiment corresponds to a further improvement of the screw cap opening device of the first embodiment. As shown in the figure, the drop-shaped opening 2 of the first embodiment is bent to form a beveled opening. A large curved surface (upper wall in the figure) of the inner wall of the opening is provided with a saw blade-shaped friction structure surface, and the other wall including the small curved surface is made a smooth surface It is shown.

In the case of this embodiment, the contact position on the outer peripheral surface of the screw cap that contacts the large curved surface of the inner wall and the smooth wall surface of the small curved line surface on the friction structure surface portion provided on the large curved surface of the opening. By forming the connected straight line in a curved shape so as to always be located ahead of the center of the screw cap, that is, in a direction in which the opening of the muzzle shape is smaller, the automatic biting action of the screw cap is more effective than in the first embodiment. It also has an excellent effect that is performed accurately.
Other members, parts, and configurations are the same as those in the first embodiment, and thus description thereof is omitted.

Hereinafter, an opening method using the screw cap opening tool of the present invention will be described with reference to FIG. FIG. 3 shows a second embodiment of the present invention, in which a credit card type screw cap opening tool having a muzzle-shaped opening is used to open the screw cap of a plastic bottle. .

From above the screw lid P, the inner wall of the opening is fitted so as to be in contact with two points on the outer periphery of the lid, the container B is pressed with the other hand H, and the card is turned in the opening direction L shown in the figure, thereby turning the screw lid. The outer peripheral surface is acted upon by a force to move to the smaller opening, and an automatic biting action occurs, so that the outer periphery of the card and the screw cap is more firmly restrained and slippage is prevented, and the screw cap P has a smaller height than its center. The contact point of the finger on the outer peripheral edge of the distant card becomes a point of leverage and generates a large rotational moment. Therefore, the lid can be easily turned and opened with a small force.

  FIG. 4 shows a usage example 2 of opening a screw cap of a container having a screw cap having a smaller outer shape. The method of use is the same as that of Use Example 1, except that the automatic bite-in action is performed without any step to the back of the opening. Indicates that you can do it.
