Patent Document 1

Patent Document 2

[0004] Conventional PET bottle openers disclosed in Patent Documents 1 to 3 have the following problems. In the PET bottle opener of Patent Document 1, the long handle has the shape of a single round rod, making it difficult to properly press the long handle against a wall or desk when opening the cap, and thus it cannot be securely fixed. Furthermore, in this state, the user needs to place the pads of their fingers on the seven protrusions on the outer surface and rotate the PET bottle opener, making it difficult to operate. The PET bottle opener of Patent Document 2 cannot be opened with one hand. The PET bottle opener of Patent Document 3 proposes a structure that can be opened with one hand, but it has the disadvantage of being impractical because it is not easy to fix the PET bottle itself in place.

Modes for Carrying Out the Invention

[0016] Hereinafter, preferred embodiments (examples) of the present invention will be described based on the accompanying drawings.

[0017] A typical embodiment of the PET bottle opener according to the present invention will be described with reference to FIGS. 1 to 7.

[0018] In Figure 1, etc., 1 is the main body of the PET bottle opener according to this embodiment. As functional elements, the main body 1 is configured to include an engaging portion 2 located on the lower side and a locking portion 3 located on the upper side, as shown in Figures 1, 2, and 5. The engaging portion 2 is the part that engages with the cap of a PET bottle in a fitted relationship. The locking portion 3 is the part that has a shape that allows it to lock onto other fixed parts (fixed objects or installed objects, etc.) such as pillars, desks, general furniture, office furniture, and walls, or the end of an immovable plate-like part such as a desk, when performing the action of removing the PET bottle cap. Preferably, the main body 1 of the PET bottle opener is integrally formed as a whole by molding a resin material having the required hardness, or by molding wood. Alternatively, the engaging portion 2 and the locking portion 3 can be made separately and then joined together to make the main body 1.

[0019] As shown in Figures 1 to 5, the overall external shape of the engagement portion 2 is preferably a relatively flat rectangular parallelepiped, but it is not limited to this, and the external shape can be made arbitrarily. The thickness dimension of the engagement portion 2 is set to be approximately equal to the height dimension of the PET bottle cap. In particular, as shown in Figures 2 to 5, a hole 4 is preferably formed through the engagement portion 2, with a central axis in the direction of axis B in the figure. The inner diameter of the hole 4 is set to a diameter dimension that is approximately the same as the outer diameter of a typical PET bottle cap. Furthermore, on the entire or a part of the inner circumferential surface of the hole 4, uneven parts (anti-slip jagged vertical grooves) 5 are formed at required locations in the circumferential direction. The uneven parts 5 can be formed over the entire circumference of the inner circumferential surface, or at any multiple locations or at one location. When a PET bottle cap is inserted into the hole 4 of the engagement portion 2 from the lower side of the main body 1 and attached, these uneven parts 5 engage with the jagged vertical grooves formed on the outer circumferential surface of the cap. In other words, the engaging portion 2 of the main body 1 of the PET bottle opener engages with the PET bottle cap in a fitting relationship via the recessed portion 5 through its hole 4.

[0020] The external shape of the engaging portion 2 is not limited to a flat rectangular parallelepiped, and the overall shape can also be formed into a ring shape with a hole 4 having the above-described structure.

[0021] As is clear from Figures 1 to 5, the locking portion 3 is preferably formed as two opposing wall portions 6 erected along the two edges of the upper surface of the flat rectangular parallelepiped engaging portion 2. The two wall portions 6 are formed in a parallel positional relationship so as to face each other with the hole portion 4 of the engaging portion 2 positioned between them. Furthermore, the upper end of each of the two wall portions 6 is formed to have a bevel 7. The bevel 7 of each of the two wall portions 6 preferably consists of two surfaces 7 that intersect at a right angle, as shown in Figures 2 and 5. a The angle of the inclination is set so that it is included in each of the two wall portions 6 of the locking portion 3. That is, each of the two wall portions 6 of the locking portion 3 is formed to include an inclination 7 that intersects at a right angle at its upper end (or outer end). However, this intersection angle is not limited to a right angle. It can be set to any angle as long as it produces the function described later. The function of the locking portion 3 will be described later.

[0022] The wall portion 6 described above can also be formed in an alternative shape, such as a comb-like shape or a single or multiple rod-like shape. Furthermore, if the engagement portion 2 is formed in a ring-like shape with a hole 4 having the above structure, it is preferable that the portion corresponding to the wall portion 6 be formed in a shape that can be arbitrarily changed according to the external shape of the engagement portion 2.

[0023] Figure 6 shows the mounting state of the PET bottle opener according to this embodiment. Specifically, it shows the state in which the main body 1 of the PET bottle opener is attached to the cap 9 of the PET bottle 8. In this mounting state, the cap 9 is inserted into the hole 4 of the engaging portion 2 of the main body 1, and in this fitted state, the jagged vertical grooves of the cap 9 engage with the uneven portion 5 of the hole 4.

[0024] Figure 7 shows the usage state of the PET bottle opener according to this embodiment. In this usage state, with the PET bottle opener attached as shown in Figure 6, force is applied to both sides of the corner 10a of a fixed object (fixing part) 10 such as a column, bringing the two inclined surfaces 7 of the locking part 3 of the main body 1 into contact with each other, and the PET bottle 8 itself is rotated counterclockwise (opening direction) C. As a result, the movement of the main body 1 is restricted by the contact action of the locking part 3 of the main body 1, and the engaging part 2 of the main body 1 and the cap 9, which are integrated based on the engagement relationship, are rotated relative to the PET bottle 8 in the opening direction (clockwise in this case). In this way, the cap 9 of the PET bottle 8 is opened by the PET bottle opener according to this embodiment, i.e., the main body 1. This illustrated example shows the usage state using a vertical corner 10a, but it is not limited to this, and can also be used with horizontal corners or corners in other angular directions.

[0025] The operation of attaching the bottle opener as shown in Figure 6, and the operation of using the bottle opener as shown in Figure 7, can, in principle, be done with only one hand. Therefore, it is a convenient bottle opener for people with limited use of one hand. On the other hand, it can, of course, also be done with both hands.

[0026] Other possible fixing points include the edges of flat surfaces on fixtures such as desks and tables, and the corners of fixed structures such as pillars and fences.

[0027] Furthermore, given the shape of the main body 1 of the PET bottle opener described above, it can also be used to attach to other fixed or installed objects by utilizing the space between the two wall sections 6.

[0028] The configurations, shapes, sizes, and arrangements described in the above embodiments are merely schematic representations to the extent that the present invention can be understood and implemented, and the composition (materials), etc., of each component are merely illustrative. Therefore, the present invention is not limited to the described embodiments and can be modified in various forms as long as it does not deviate from the scope of the technical idea set forth in the claims. [Industrial applicability]
