Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings.
As shown in fig. 1 to 7, the present embodiment provides a bottle, which includes a bottle mouth 3 and a bottle cap 1, wherein the bottle cap 1 is a cylindrical structure with a closed top and an open bottom, an annular inner plug 11 is formed by extending downward on the inner surface of the top of the bottle cap 1, and an elastic annular inner pad 2 is disposed on the inner surface of the top of the bottle cap 1 and at the periphery of the annular inner plug 11. The bottle mouth 3 is inserted between the inner side walls of the annular inner plug 11 and the bottle cap 1, the outer side wall of the bottle mouth 3 is detachably and fixedly connected with the inner side wall of the bottle cap 1, the inner side wall of the bottle mouth 3 and the outer side wall of the annular inner plug 11 form interference fit, and the top end face of the bottle mouth 3 abuts against the lower surface of the elastic annular inner pad 2.
The bottle mouth 3 in the embodiment is formed by adopting an extrusion-blowing process, the bottle mouth 3 is a polyethylene bottle mouth and is made of a PE material, the forming is easy, and the food safety is high. The elastic annular inner pad 2 is made of elastic material, for example, thermoplastic elastomer (POE plastic), or rubber pad. During production, firstly, an integral structure of the bottle cap 1 and the annular inner plug 11 is obtained by adopting integral injection molding of PE materials, then the elastic annular inner pad 2 is formed by adopting POE materials through injection molding on the basis, so that the upper surface of the elastic annular inner pad 2 and the inner surface of the top of the bottle cap 1 are prefabricated together, and the elastic annular inner pad 2 and the bottle cap 1 are integrally used during use.
Therefore, in the bottle in the embodiment, after the bottle cap 1 is connected with the bottle mouth 3, the elastic annular inner pad 2 is tightly combined with the top end face of the bottle mouth 3, and the elastic characteristic of the elastic annular inner pad 2 is utilized to achieve the effect of tight sealing and serve as outer sealing; meanwhile, the inner side wall of the bottle mouth 3 and the outer side wall of the annular inner plug 11 form interference fit, so that a tight sealing effect is achieved, and the inner seal is used as an inner seal. When the top end surface of the bottle mouth 3 is uneven, the elastic annular inner pad 2 with elasticity has a compensation effect on the bottle mouth. Thus, the annular inner plug 11 is in interference fit with the inner side wall of the bottle mouth 3, and even if the cover rises to a certain extent in the opening process, the sealing of the annular inner plug cannot fail; on the other hand, even if the top end face of the bottle mouth 3 is uneven, the elastic characteristic of the elastic annular inner pad 2 can also compensate the unevenness, the tightness of sealing is further ensured, the sealing is more reliable, and the adaptability to the bottle mouth 3 is stronger.
In a specific implementation manner, as shown in fig. 3 and 7, in order to facilitate assembly and ensure sealing performance, the edge of the mouth 3 extends upwards to form an annular sealing neck 31 with a reduced bore, the top edge of the annular sealing neck 31 is turned outwards to form a pressure-bearing ring 32, the upper surface of the pressure-bearing ring 32 forms the top end surface of the mouth 3, and the inner side wall of the annular sealing neck 31 forms an interference fit with the outer side wall of the annular inner plug 11. It will be appreciated that the outer diameter of pressure-bearing ring 32 is generally smaller than the outer diameter of finish 3. Preferably, the inner wall of the junction of the annular sealing neck 31 and the pressure-bearing ring 32 forms a transition arc 33 to guide the assembly of the bottle cap 1 and the bottle mouth 3.
In addition, a support ring 34 is formed on the outer sidewall of the mouth 3 and below the cap 1 to support the mouth 3 during the cap-placing process. The support collar 34 facilitates the support of the bottle mouth 3 on the corresponding equipment for the mounting of the bottle cap 1.
Further, in order to fix the bottle mouth 3 and the bottle cap 1, the outer side wall of the bottle mouth 3 is connected with the inner side wall of the bottle cap 1 through a threaded structure.
Specifically, the thread structure comprises an external thread 35 arranged on the outer side wall of the bottle mouth 3 and an internal thread 12 arranged on the inner side wall of the bottle cap 1, the two threads are fixed in a thread screwing mode, and the operation is simple and convenient.
During installation, the bottle cap 1 is in rotating fit with the external thread 35 of the bottle mouth 3 through the internal thread 12 until the lower surface of the elastic annular inner pad 2 contacts with the top end face of the bottle mouth 3, and the elastic annular inner pad 2 can be tightly combined with the top end face of the bottle mouth 3 through the screwing force of the threads.
Of course, the connection between the outer sidewall of the bottle mouth 3 and the inner sidewall of the bottle cap 1 can be realized in other manners, and this embodiment is only an example.
In practical applications, for facilitating the screwing of the bottle cap 1 by the operator, vertical stripes 13 are formed on the outer side wall of the bottle cap 1 to increase the friction between the human hand and the bottle cap 1.
Further, a gel storing groove 14 is formed in the center of the upper surface of the bottle cap 1.
Because the bottle cap 1 is molded by an injection molding process during processing, molten materials are injected into a mold cavity of a mold during injection molding, and when the injection is finished, the materials may overflow to cause the top surface of the bottle cap 1 to have a convex prick. Through the arrangement of the glue hiding groove 14, the overflowing part can be hidden in the glue hiding groove 14, and the phenomenon that a user is cut due to the fact that protruding burrs exist on the top surface of the bottle cap 1 is avoided.
Further, the bottle also includes a bottle body (not shown in fig. 1) that is open at the top and closed at the bottom, and a bottle mouth 3 is formed at the top open end of the bottle body.
The cross sections of the bottle cap 1 and the bottle mouth 3 are circular, and the shape of the bottle body can be designed according to needs. In this embodiment, the side of the bottle body has a handle. The bottle body with the handle can not adopt an injection molding process, and can only be formed by an extrusion-blowing process, so that the bottle mouth 3 is easy to be uneven, the elastic annular inner pad 2 can well compensate, and the sealing reliability is improved.
The above are merely exemplary embodiments of the present invention, and are not intended to limit the scope of the present invention. Any person skilled in the art should also realize that such equivalent changes and modifications can be made without departing from the spirit and principles of the present invention.
