Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bottle caps, in particular to an inner sleeve which can prevent being pulled out. Background Art
[0002] The inner sleeve is the name of an inner part on the bottle cap structure. Its main function is to connect various other accessories of the bottle cap. It also has a buckle function, so as to prevent the bottle and the cap from separating after matching with the bottle. The materials used for connecting the inner sleeve of the existing bottle caps on the market are PC, PET, and AS welding ABS. These materials are the basic materials for connecting the inner sleeve in the current plastic bottle cap industry. The existing technical defects mainly include the following points: the bottle cap is easy to be physically removed after being put on the bottle, resulting in reduced anti-counterfeiting of the bottle cap. Utility Model Content
[0003] The purpose of the utility model is to provide an anti-pushing inner sleeve to solve the problems raised in the above background technology.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-pull inner sleeve, comprising an inner sleeve body and a reinforcement installed inside the inner sleeve body; the reinforcement comprises an outer ring, and an undercut is provided on the outer ring; the undercut is also provided with a protrusion formed by a stamping process.
[0005] As a preferred technical solution of the present utility model: the reinforcement is made of steel and is integrally formed with the inner sleeve body through an injection molding process.
[0006] As a preferred technical solution of the utility model: a notch is further provided on a side of the outer ring away from the undercut.
[0007] By adopting the above technical scheme, the beneficial effect of the utility model is that when the inner sleeve body is installed on the bottle mouth, the setting of the reinforcement member can improve the strength of the inner sleeve body after being connected to the bottle mouth, and at the same time, the inner sleeve body is clamped on the bottle by the inverted buckle, so the tensile strength of the inner sleeve body can be improved, thereby solving the problem that the inner sleeve body is easily pulled off the bottle under physical force.

[0011] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.
[0012] See also Figure 1-2 The utility model provides an embodiment: an anti-pull inner sleeve, including an inner sleeve body 1 and a reinforcement member 2 installed inside the inner sleeve body 1; the reinforcement member 2 includes an outer ring 23, and an undercut 22 is provided on the outer ring 23.
[0013] In summary, when the inner sleeve body 1 is installed on the bottle mouth, the provision of the reinforcement member 2 can enhance the strength of the inner sleeve body 1 after being connected to the bottle mouth, and at the same time, the undercut 22 is used to clamp on the bottle, so the tensile strength of the inner sleeve body 1 can be enhanced, thereby solving the problem that the inner sleeve body 1 is easily pulled off the bottle under physical force.
[0014] In addition, the reinforcing member 2 is located inside the inner sleeve body 1 and is wrapped in the middle by the plastic of the inner sleeve body 1 , and the elasticity of the plastic material is utilized to reduce the damage of the inner sleeve body 1 to the bottle mouth.
[0015] Furthermore, since the reinforcement 2 is made of steel and is integrally formed with the inner sleeve body 1 through an injection molding process. When the steel reinforcement 2 is integrally formed with the inner sleeve body 1 through an injection molding process, the reinforcement 2 is wrapped in the inner sleeve body 1 made of plastic through injection molding, so that after the inner sleeve body 1 is buckled on the bottle mouth, the strength of the connection between the inner sleeve body 1 and the bottle is greatly improved due to the support of the reinforcement 2, and the anti-counterfeiting requirements can be met in both high and low temperature environments. The inner sleeve adopts a combination of plastic and steel, and the steel reinforcement 2 is wrapped in plastic in the middle. The plastic part can be made of food-grade material, thereby ensuring that the product has strength and food safety.
[0016] At the same time, the reinforcement 2 is wrapped in plastic in the middle, so that the reinforcement 2 is in a closed state and does not come into contact with the outside environment, thereby avoiding natural oxidation of the reinforcement 2 and ensuring food safety.
[0017] On the basis of the above scheme, since the undercut 22 is also provided with a protrusion 21 formed by a stamping process, the protruding surface of the protrusion 21 is higher than the surface of the undercut 22, and the concave surface of the protrusion 21 is lower than the surface of the undercut 22. Therefore, after injection molding, the degree of integration of the reinforcement 2 and the inner sleeve body 1 is higher, thereby improving the connection strength between the inner sleeve body 1 and the reinforcement 2 and also improving the anti-pullout ability of the device.
[0018] Furthermore, since the outer ring 23 is provided with a notch 20 on a side away from the undercut 22 , the inner sleeve body 1 made of plastic and the reinforcement member 2 made of metal are more stable after being fused.
[0019] In summary, through the above scheme, the pulling force of the bottle cap can be increased, thereby solving the problem that the bottle cap is easily pulled off the bottle under physical force; at the same time, the anti-counterfeiting function of the bottle cap product is improved, which can prevent malicious destruction of products and malicious claims in the market; in particular, the adaptability of the bottle cap product under high and low temperature conditions is enhanced, ensuring that the bottle cap product has higher resistance to high and low temperatures, preventing malicious high and low temperature damage, thereby enhancing the anti-counterfeiting function of the product.
[0020] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
