Description

Screw cap opener

Technical Field

The utility model relates to a screw cap opener, it can easily open the bottle lid of the container that has the screw cap such as beverage container.

Background

When a person needs to open a beverage container with a screw cap from the outside, the beverage container is generally opened by hand. However, depending on the container, the screw cap of some containers is very tight, which makes it difficult for the elderly or people with weak finger strength to open the container by hand. There are many bottle openers available on the market that are capable of opening containers with threaded caps.

Although various bottle openers that can be carried around are commercially available, most bottle openers can be used only for opening container caps with fixed sizes, and in terms of being used for opening screw caps of various containers, reference 1 describes a multi-stage portable bottle opener.

However, the multi-segment portable bottle opener described in the reference 1 (japanese patent publication 2011-57240) is suitable for a plurality of limited bottle cap sizes (diameters), and has a large thickness as the number of bottle caps to be used increases, and even if it can be carried around in a pocket of clothes or a small bag in a child-mother bag, it is difficult to put it in a card holder or a business card holder of a wallet.

Therefore, with the popularization of vending machines and the development of an aging society, it is expected to develop a multifunctional one-type bottle opener which is simple in use method, small in size, convenient to carry about, and capable of easily opening screw caps of various diameters with one tool.

Disclosure of Invention

An object of the utility model is to provide a multi-functional single type screw cap opener, application method is simple, easily hand-carries, and old person or the weak people of finger strength also can just easily open the screw cap of various different diameters with an utensil.

The utility model discloses a screw cap opener's characterized in that is provided with the opening that the water droplet shape link up on the platelike body base plate of credit card shape in the inside wall with the screw cap contact of opening, only one side is provided with strong friction structure surface, further, through with the opening is crooked to collude the jade form, utilizes the limited platelike body base plate of area to open the screw cap that more sizes are different. In addition, the main structural feature of the strong friction structure surface provided in the inner side wall of the opening portion is that the inner wall of the opening portion is continuously brought into contact engagement with the outer periphery of the screw cap irrespective of the size of the screw cap, and the screw cap can be easily opened by firmly clamping the screw cap and applying a large rotational torque.

The plate-like body substrate of the present invention is preferably made of a material that is as light and strong as possible, based on the shape and size of the credit card. When a hard material such as metal is used, it is preferable to slightly chamfer the outer peripheral edge of the card case or provide a thin protective member in order to accommodate the card case in a wallet, a ticket case, or the like. The size and shape of the plate-like body or the size of the opening are not limited to the credit card shape, and are design matters that can be freely selected depending on the use environment.

Further, if it is desired to use a large number of screw caps having a large outer dimension in a plate-shaped substrate having a limited area, since the drop-shaped opening is long, in order to effectively utilize the limited area of the plate-shaped substrate, the drop-shaped opening is bent to form a through opening having a hook-jade shape (see fig. 2). When the hook jade-like shape is formed, the bending line surface formed on the plate-like body substrate is formed into the following bending shape, so that the screw cap can be more smoothly and accurately embedded: a straight line connecting points at which the outer peripheral surface of the screw cap contacts the large curved surface and the small curved surface of the inner wall is always at a position ahead of the midpoint of the screw cap, i.e., at the side where the hook-jade-like opening portion is smaller.

The utility model discloses a water droplet shape opening is also good, colludes jade form opening and also is good, all only be formed with the friction structure surface portion (for example the unsmooth of little cockscomb structure) that has strong locking power in one of them side of the inner wall with the contact of screw cap peripheral surface, other peripheral surface contact surfaces are whole to be constituted by the smooth surface on non-friction structure surface portion. Even if the positions of the friction structure surface portion and the smooth surface portion are reversed, the effect of continuously gripping and rotating the screw cap is the same regardless of the size of the screw cap, but if the position of the friction structure surface portion is reversed, the direction of rotating the screw cap is also reversed.

The utility model discloses a make set up in the friction structure surface portion of the opening inner wall that the water droplet shape of platelike body base plate link up and the screw cap one side contact surface of initial contact carry out abundant meshing to rotate the screw cap a little, thereby make the periphery surface of screw cap firmly with the meshing of opening inner wall. Therefore, when the outer edge portion of the plate-like body base plate or a portion near the outer edge portion is gripped by fingers and rotated, a large rotational moment can be generated based on the lever principle caused by the difference in distance between the diameter midpoint of the screw cap and the position of the plate-like body base plate gripped by hand. Further, by bending the drop-shaped opening to form a hook-jade-shaped opening, the effect of automatic engagement is better, and more screw caps of different sizes can be opened in a plate-shaped substrate with a limited area.

Furthermore, the utility model discloses a screw cap opener, through making into the shape and the size of credit card, not only can put into small article boxes such as wallet or business card holder portably and hand-carry, even only one piece has water droplet shape opening or colludes jade form open-ended platelike body base plate moreover, the screw cap of the various containers that kind and size are different such as from the plastic bottle of vending machine to health food or skin care products is all applicable, has outstanding multi-functional single type effect.

The screw cap opener of the utility model is only composed of 1 credit card shaped plate-shaped body base plate. Although a stainless steel substrate is used in the embodiment, in practical use, it is often put in a card case such as a business card holder or a wallet which is commonly used and carried around, and therefore, a material which is as light and strong as possible is preferable, and a material which can withstand the use strength of light metal or synthetic resin or the like and can be engraved or printed on the surface thereof is preferable.

The base plate 1 is provided with a through opening 2 for inserting a screw cap. The opening 2 is configured as a drop-shaped opening, and the inner wall of the opening 2 is provided with a strong friction structure surface part 2a and other smooth surface parts 2b of a non-friction structure surface, the strong friction structure surface part 2a being provided only on one side of the inner wall contacting with the outer periphery of the screw cap. According to the present embodiment, the friction structure surface part 2a is located on the upper side wall of the opening part in the drawing, and the other walls are all smooth surface parts. The friction structure surface may be, for example, a small serrated or irregular friction structure surface, or a structure surface having a shape and size that has a slip-preventing function and is engaged with a slip-preventing texture pattern provided on the surface of a conventional container screw cap.

The size and shape of the plate-like body substrate 1 are basically manufactured in accordance with the shape and size of a credit card of international standard, but may be freely designed in accordance with the use environment and the user's needs without being restricted by the international standard. In addition, in order to provide safety and good tactile sensation in portability and handling, it is preferable to perform additional design processing such as appropriately rounding the corners of the substrate, applying a chamfer, providing a protective cover, or the like. Reference numeral 3 denotes an outer edge portion of the substrate, and 4 denotes a mounting hole for a pendant.

Example 2
