Example

As shown in Figure 1, the bottle cap of the present invention includes a body 1, a pressing ring 2 and a knob 3.

Among them, the body 1 includes an outer ring 11, an inner ring 12 and an isolation layer 13.

The top of the inner ring 12 is connected to the inner wall of the outer ring 11. A gap is formed at the joint between the inner ring 11 and the inner ring 12 for the bottle mouth 81 to be inserted.

The inner side wall of the outer ring 11 is provided with an outer ring thread 14 which can be matched and connected with the outer thread of the bottle mouth 81.

The bottom of the inner ring 12 is provided with an isolation layer, that is, a sealing film 13. The sealing film 13 can be fixedly connected to the bottom of the inner ring 12 by adhesion or other connection methods. The sealing film 13 is aluminum foil, and the surface of the aluminum foil is coated with a layer of epoxy resin.

Wherein, the lower end of the inner ring 12 may be arranged flush with the lower end of the outer ring 11, or may be higher or lower than the lower end of the outer ring 11, depending on the structure of the specific bottle body.

Preferably, the lower end of the inner ring 12 is slightly inclined, so that the sealing film 13 has a certain inclination angle. After the sealing film 13 seals the end of the inner ring 12, the content of the material is located closer to the inclined one under the action of gravity. side. At the same time, the end of the inner cover 3 connected to the sharp mechanism 33 also has a certain angle of inclination (as shown in the cross-sectional view of Fig. 5 and the side view of Fig. 6, the angle of inclination makes the end of the knob 31 a distinct wedge shape). In this way, after the sharp mechanism 33 pierces the sealing film 13, the material in the inner cavity 5 immediately falls into the bottle from the lower side. With the rotation of the knob 31, the cooperation between the end of the inner cover 3 and the sharp mechanism 33 will quickly open the sealing film 13, and finally all the materials will quickly fall into the bottle, and the sealing film 13 is still connected to the end of the inner ring 12. Does not fall.

Wherein, the pressing ring 2 is a hollow ring-shaped structure. A pressing ring thread 21 is provided on the inner side wall of the pressing ring 2 and is matched with the external thread 321 on the thread ring 32 of the knob 3.

The pressing ring 2 can be made of various materials such as PP plastic and HDPE plastic.

The function of the press ring 2 is to reduce the complexity and cost of bottle cap production. If the pressure ring and the outer ring 11 are integrated, the manufacturing and assembly of the knob 3 will be much more difficult.

The top of the knob 3 is provided with a rotating mechanism 31, which is a handle in this embodiment. The knob 3 is provided with a threaded ring 32, and an external thread 321 is provided on the outer surface of the knob 3, and the thread is matched with the pressing ring thread 21 of the pressing ring 2. The lower end of the knob 3 is provided with a sharp mechanism 33, which is a spike in this embodiment. A cavity 34 is formed inside the knob 3.

Wherein, the knob 3 is matched and connected with the pressing ring thread 21 provided on the inner side of the pressing ring 2 through the external thread 321 on the screw ring 32 thereof.

The pressure ring 2 and the body 1 are tightly connected by the interference fit generated by the rotary extrusion between the knob 31 and the pressure ring 2, so as to achieve a sealing effect.

The knob 3 is further provided with a sealing thread 36; the sealing thread 36 and the inner ring 12 are in interference fit.

The inner ring 12 and the sealing film 13 constitute a hollow cavity 34. In the cavity, materials for preparing beverages can be placed in advance. The materials include, but are not limited to, materials in various forms such as solids, particles, powders, flakes, liquids, and colloids that are suitable to be placed therein. Preferably, a particulate material suitable for instant dissolution can be placed. During the processing, the material can be put into the cavity first, and then the sealing film 13 can be fixedly connected to the bottom of the inner ring 12.

Among them, in order to ensure the complete and effective sealing of the sealing film 13, the lower end of the sharp mechanism 33 should be set higher than the sealing film.

When in use, turn the handle to push the entire knob 3 downwards in a spiral manner. The lower end of the sharp mechanism 33 will first touch the sealing film 13, and then insert and puncture the sealing film 13, so that the material placed in the cavity will pass through the crack of the sealing film. The opening falls into the bottle and dissolves in the liquid (such as water) in the bottle.

Among them, the shape, number, material, angle, position, etc. of the spikes are not limited, and a suitable structure that can destroy the sealing film can be adopted. Preferably, the shape of the spike is half-leaf or knife-point; the number is one; and the material is PP plastic.

Further, the bottle cap may be provided with a shell 4, and the top of the shell 4 is connected to the top of the outer ring 11. The shape design of the housing 4 is not limited to the illustration, and may be any suitable possible shape. The outer shell can be used to reinforce the bottle cap and increase the firmness, or it can be designed for the overall aesthetics of the product. The lower end of the shell matches the design of the bottle body.

Furthermore, a gasket 5 can be provided in the bottle cap. The gasket 5 is arranged in the gap formed between the inner ring 11 and the inner ring 12, and the gasket 5 can effectively prevent the liquid in the beverage bottle from leaking from the gap between the inner ring 12 and the inner wall of the bottle mouth 81.

The shape, material, thickness, and size of the gasket 5 are not limited, and any suitable material, thickness or size that can effectively prevent leakage can be used. Preferably, the gasket 5 is a silicone ring.

Further, the interference fit between the outer wall of the knob 3 and the inner ring 11 of the body 1 can effectively prevent the liquid in the beverage bottle from leaking from the gap between the outer wall of the knob 3 and the inner wall of the inner ring 12.

Preferably, the inner ring 12 and the outer ring 11 are connected by a connecting portion 121; the top of the connecting portion 121 is provided with a sealing mechanism 35; the sealing mechanism 35 can contact the threaded ring 21 and form an interference fit, so that the sealing film can still be punctured. The overall cap does not leak.

In one embodiment, a beverage bottle includes a bottle body 8 and a bottle cap. Among them, the bottle mouth 81 can be inserted into the gap formed by the inner ring 12 and the outer ring 11; the external thread at the bottle mouth 81 is matched with the outer ring thread 14 on the inner side wall of the outer ring 11.

In another embodiment, an internal thread is provided on the inner side of the bottle mouth 81, and correspondingly, a thread corresponding to the internal thread of the bottle mouth 81 is provided on the side wall of the inner ring 12 of the body 1 in the bottle cap. The bottle mouth 81 can also be fixedly connected to the gap between the inner ring 12 and the outer ring 11 by screw insertion.

In use, the bottle mouth 81 is screwed into the gap between the inner ring 12 and the outer ring 11, and the gasket 5 further strengthens the sealing.

In use, the user rotates the top knob of the bottle cap clockwise to the end, about 300-350 degrees, after the material stored in the cavity falls into the bottle, then rotate the outer cap counterclockwise in a normal way to drink normally. Since the top of the pressing ring thread 21 is provided with a limit mechanism 211 for restricting the knob 3 from moving upward, the knob 3 will not be separated from the bottle cap.

In practice, due to the characteristics of glass during the processing of glass bottles, there is inevitably a thickness error between the mouth and the inner wall of the bottleneck. As shown in Figure 12, the diameter error between the mouth and the inner wall of the bottleneck is 1.25mm. The formation of this error will cause the outer wall of 12 to touch the inner wall of the bottleneck when the bottle cap is tightened, and the bottle cap cannot be tightened normally. The error problem in the actual production of the present invention is optimized as follows: 1. Adjust the glass bottle grinding tool The precision makes the thickness of the bottle mouth and the bottleneck more uniform; 2. The lower thread of the sealing thread 36 is slightly protruding than the upper thread, and the protrusion will make the knob rotate clockwise downwards to produce an interference fit. Press the knob 3 so that the error between the bottle mouth and the inner wall of the bottleneck does not affect the operation and opening of the bottle cap.

In use, the method for using and assembling the bottle cap and the beverage bottle of the present invention includes the following steps:

(1) Screw the knob into the pressing ring through the thread;

(2) Press the assembled knob and pressing ring into the body of the bottle cap together. You can also install the silicone ring between the inner ring and the outer ring in the bottle cap body;

(3) Fill the cavity formed by the knob and the inner ring with materials (such as powder), seal the lower end of the inner ring, and install the sealing film;

(4) The assembly line fills the bottle body with solution (such as water), inserts the mouth of the bottle body into the body of the bottle cap, and tightens it to make the bottle body and the cap tightly connected and fixed.

The bottle cap of the present invention can be used alone as a storage vessel for containing materials (such as powder), and can also form a novel integrated beverage bottle with a bottle body with the same standard. The purpose of preparing different drinks can be realized by changing the caps of beverage bottles. The replacement of bottle caps is convenient and quick, realizing diversified product development and high efficiency.

The protection content of the present invention is not limited to the above embodiment. Without departing from the spirit and scope of the concept of the present invention, changes and advantages that can be imagined by those skilled in the art are all included in the present invention, and the scope of protection is covered by the appended claims.
