Description

Technical Field

[0001] This utility model belongs to the field of bottle opener technology, specifically relating to a bottle opener that is compatible with plastic bottle caps of various sizes. Background Technology

[0002] In daily life, we need to use various types of bottles, and the corresponding bottle caps are also different sizes. To achieve a better sealing effect, the bottle cap and the bottle are mostly connected by a screw thread, and the connection between the two is relatively tight. Bottle openers can quickly open bottle caps, such as those shown in CN202220209949.2. Although they can meet the bottle opening needs of general situations, they can only open bottle caps of one size. When the bottle cap size is different, they cannot effectively open the bottle. Moreover, conventional bottle openers do not have anti-slip structures, and they cannot effectively bite bottle caps made of rigid materials, which also affects the effectiveness of opening a bottle. They are difficult to meet the needs of different situations and their applicability is limited. Summary of the Invention

[0003] The purpose of this invention is to provide a bottle opener with a reasonable structure and strong versatility that is compatible with plastic bottle caps of various sizes.

[0004] The technical solution to achieve the purpose of this utility model is a bottle opener that is compatible with plastic bottle caps of multiple sizes, including a bottle opener body, wherein a plurality of concentric opening cavities with gradually increasing diameters are provided in the middle of the bottle opener body.

[0005] The inner wall of the bottle opening cavity is uniformly fixed with anti-slip serrations;

[0006] The lower side wall of the bottle opener body has several buffer strip grooves that communicate with the bottle opening cavity.

[0007] A further preferred embodiment is that a boss is formed between adjacent buffer strip grooves, and the lower part of the outer wall of the boss is integrally formed with several vertical protrusions for increasing friction.

[0008] A further preferred embodiment is that the bottle opener is a one-piece molded rubber bottle opener.

[0009] A further preferred embodiment is that the anti-slip teeth are bidirectional oblique teeth, and the inclination angle of the bidirectional oblique teeth is 15-30°.

[0010] A further preferred embodiment is that the height of the bottle opener body is 45cm.

[0011] A further preferred embodiment is that the diameter of the bottle opening cavity is in the range of 28-65 mm.

[0012] This utility model has the following positive effects: Its structure is rationally designed, featuring several concentric opening cavities with gradually increasing diameters. This allows for different cap insertion and opening operations, expanding its applicability. Furthermore, the inner wall of each opening cavity has anti-slip serrations that effectively engage with the outer edge of the cap, improving the effectiveness and reliability of opening. Additionally, it includes a buffer groove that allows the cap to open slightly during insertion and securely hold the cap to its outer edge, ensuring stable opening, convenient operation, and strong applicability.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] See Figures 1 to 3As shown, a bottle opener adaptable to multiple sizes of plastic bottle caps includes a bottle opener body 1, with several concentric opening cavities 2 of gradually increasing diameter arranged in the middle of the bottle opener body. In this embodiment, the height of the bottle opener body is 45cm. The diameter of the opening cavities ranges from 28-65mm. This allows it to meet the opening operation of bottle caps of different sizes, improving its applicability. Moreover, the bottle opener is a one-piece molded rubber bottle opener. The elasticity of the rubber material provides higher compatibility and anti-slip properties. In this embodiment, the rubber material is a hard rubber material, specifically a rubber composite material, and is food-grade rubber with a temperature resistance range of -20℃ to 80℃, ensuring safety and durability. It has a certain degree of elasticity but will not deform to a large extent, thus improving the reliability of the engagement with the bottle cap when it is inserted, without deforming during rotation and affecting the effectiveness of opening the bottle.

[0020] In this embodiment, anti-slip serrations 3 are uniformly fixed on the inner wall of the bottle opening cavity; the anti-slip serrations are bidirectional oblique teeth, and the inclination angle of the bidirectional oblique teeth is 15-30°. When not under force, they are in a naturally contracted state, and when under force, they expand to fit the bottle cap, forming a self-locking effect, improving the effectiveness and reliability of the user opening the bottle.

[0021] Meanwhile, the lower side wall of the bottle opener body is provided with several buffer strip grooves 4 that communicate with the bottle opening cavity. When the bottle cap is inserted, the buffer strip grooves can expand and contract within a certain range to ensure the effectiveness of holding the bottle cap, prevent relative displacement during opening, and improve the effectiveness of opening the bottle.

[0022] In this embodiment, a boss 5 is formed between adjacent buffer strip grooves, and several vertical protrusions 6 are integrally formed on the lower part of the outer wall of the boss to increase friction. The above structure is more ergonomic, increases grip stability, and ensures the effectiveness and reliability of opening the bottle.

[0023] This utility model has the following positive effects: Its structure is rationally designed, featuring several concentric opening cavities with gradually increasing diameters. This allows for different cap insertion and opening operations, expanding its applicability. Furthermore, the inner wall of each opening cavity has anti-slip serrations that effectively engage with the outer edge of the cap, improving the effectiveness and reliability of opening. Additionally, it includes a buffer groove that allows the cap to open slightly during insertion and securely hold the cap to its outer edge, ensuring stable opening, convenient operation, and strong applicability.

[0024] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0025] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
