Description

Technical Field

[0001] This utility model relates to the field of plastic bottle caps, and in particular, to a bottle cap preform and a bottle cap. Background Technology

[0002] A bottle cap is a lid for a sealed container. Bottle caps come in various types and can hold concentrated liquids, honey, pills, powders, etc., hereinafter referred to as storage containers. For example, Chinese invention patent number 202410079452.7, entitled "An Instant Brewing Spin-on Bottle Cap," includes a bottle cap body, a screw cap, and a storage cap. The screw cap is movably engaged with the bottle cap body, and the storage cap is threadedly connected to the bottle cap body. The storage cap has a storage cavity for storing brewing ingredients. Its disadvantage is that it has a very complex structure design with a bottle cap body, a screw cap, and a storage cap, with many parts, each of which accounts for a large proportion, resulting in a small capacity. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the existing technology and at least to some extent solve the technical problems in the related technology, providing a solution to the problem that the existing bottle cap structure design is very complex, with many parts and each part accounting for a large proportion, resulting in small capacity.

[0004] A bottle cap preform includes an integrally formed preform assembly. The preform assembly includes a cap body with a cavity, a preform body on the cap body, a cavity inside the preform body, the cavity communicating with the chamber, and a soft rubber plug for sealing the cavity.

[0005] Furthermore, the soft rubber plug includes an annular column and a spherical face. The column and face are connected by an annular inclined connecting part, so that the soft rubber plug forms a structure with a small upper end and a large lower end. The outer surface of the soft rubber plug is adapted to the cavity of the cover body.

[0006] Furthermore, the face facing the column is concave and spherical.

[0007] Furthermore, the cover is provided with an annular barb for limiting the soft rubber plug.

[0008] Furthermore, the face has a cross-shaped slit.

[0009] A bottle cap, using the aforementioned bottle cap preform, the preform being blow-molded into a container.

[0010] Furthermore, the lid body is provided with a sealing film, which covers and seals the cavity opening of the container.

[0011] Furthermore, the cover body is provided with a first sealing ring and a second sealing ring, and the sealing film is located inside the first sealing ring.

[0012] Furthermore, the sealing film is aluminum foil.

[0013] The main advantages of this invention are as follows: the cap blank is integrally formed on the cap body, and the cap blank can be blow-molded into containers of any shape. With the same wall thickness and material usage, it has a larger capacity than traditional storage containers, uses less material, has a simpler process, is easy to assemble, and saves labor. When the container is not squeezed, the soft rubber plug acts as a safety valve during short-term use to prevent the stored contents from falling out. Therefore, depending on the liquid concentration in the bottle, the user can choose whether or not to squeeze the container. Attached Figure Description

[0022] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. This application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0024] like Figure 1 and Figure 2 As shown: A bottle cap preform includes an integrally injection-molded preform assembly. The preform assembly includes a cap body 1 with a cavity 11. A preform body 2 is provided on the cap body 1. The preform body 2 is based on the same principle as the bottle preform. The bottle preform is blow-molded into any desired bottle body. Therefore, the preform body 2 is integrally molded on the cap body 1. The preform body 2 can be blow-molded into a container 4 of any shape without changing the shape of the cap body 1. The preform body 2 has a cavity 21 inside, which is connected to the cavity 11. The preform assembly is provided with a soft rubber plug 3 to seal the cavity 21. Before the preform is molded into the container 4, the soft rubber plug 3 may not be installed on the preform assembly.

[0025] like Figure 2 and Figure 3 As shown: The soft rubber plug 3 includes an annular column 31 and a spherical face 32. The face 32 is concave towards the column 31 and is spherical. When the container 4 is squeezed, the gap 34 deforms and enlarges under pressure, making it easier for the stored items to fall from the center of the face 32. Under the action of gravity, all the stored items fall, reducing waste. The face 32 has a cross-shaped gap 34 at its center. The soft rubber plug 3 is made of a relatively soft plastic material. After the soft rubber plug 3 is tightly squeezed, the gap 34 shrinks to zero gap, which is used to isolate the stored items in the container 4. The column 31 and the face 32 are connected by an annular inclined connecting part 33. The design of the inclined connecting part 33 makes the soft rubber plug 3 have a structure with a small upper end and a large lower end. The outer surface of the soft rubber plug 3 is adapted to the cavity opening of the cap body 2 to prevent excessive squeezing into the container 4. Therefore, the soft rubber plug 3 and the cap body assembly are tightly fitted to reduce the gap 34 and ensure the isolation effect.

[0026] like Figure 2As shown: The cover 1 is provided with an annular barb 12 for limiting the soft rubber plug 3, so that the soft rubber plug 3 will not fall off.

[0027] like Figure 4 , Figure 5 and Figure 6 As shown: A bottle cap, using the aforementioned bottle cap preform, the preform body 2 is formed into a container 4 by a blow molding process, the container 4 can be of any shape.

[0028] like Figure 2 and Figure 7 As shown: The cover 1 is provided with a sealing film 5, which covers and seals the cavity opening of the container 4. The sealing film 5 seals the cavity opening because during long-term storage, a small amount of the stored material may leak out from the gap 34. At this time, the sealing film 5 can completely seal the container 4.

[0029] like Figure 2 As shown: The cap body 1 is provided with a first sealing ring 13 and a second sealing ring 12. The first sealing ring 13 and the second sealing ring 12 respectively fit the inner wall and the outer wall of the bottle mouth to further achieve sealing. The sealing film 5 is located inside the first sealing ring 13.

[0030] like Figure 2 As shown: The sealing film 5 is made of aluminum foil, and the aluminum foil is used for sealing to ensure airtightness.

[0031] Operating principle: First, make an integral injection molded cap preform assembly. According to actual needs, blow mold the cap preform 2 into the required shape of container 4. Add storage material into container 4, install soft rubber plug 3, seal with aluminum foil, fill the bottle with beverage, water, etc., and screw the cap to the bottle body tightly.

[0032] When drinking, unscrew the cap, tear off the aluminum foil, tighten the cap, and squeeze the container 4. The gap 34 will deform and widen, causing the contents to fall out. When the container 4 is not squeezed, the soft rubber plug 3 acts as a safety valve for short-term use to prevent the contents from falling out. Therefore, depending on the liquid concentration in the bottle, the user can choose whether or not to squeeze the container 4.

[0033] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
