Description

Combined bottle set

Technical field

The invention relates to the technical field of food packaging, in particular to a combined bottle set.

Background technique

Chinese patent 201720861244.8 provides a portable fresh-keeping cup set. When in use, the lower container is rotated and the film at the bottom of the upper container can be mixed to mix the objects in the two containers. The two containers can be freely combined to hold different objects, that is, adjust and drink. However, the upper container and the lower container need to be formed by different molds during manufacturing. From the perspective of saving manufacturing costs, the manufacturer needs the upper container and the lower container to have the same shape and structure. The combination is not only convenient for manufacturing, but also suitable for liquids in different containers. The need for instant mixing.

Summary of the invention

The purpose of the present invention is to provide a combined bottle set, which is simple to operate and easy to use for preparing beverages, meets food safety standards, and is conducive to packaging. It can not only combine different flavor packaging and beverage packaging to meet consumer needs, but also The production cost of the packaging body is reduced.

The technical solution of the present invention: a combined bottle set comprising a bottleneck with an external thread and a bottle bottom with an inner cavity, the inner circumference of the inner cavity is arranged with an internal thread, and the top surface of the inner cavity is also arranged with a liquid mixing hole, The hole and the barrier film are combined by sticking, the outer circumference of the bottleneck is over-fitted with the inner circumference of the inner cavity, and the top of the bottleneck has a cutting edge.

Further, the top edge of the bottleneck is chamfered with a circular arc, the mixing hole on the top surface of the inner cavity extends out of the sleeve toward the bottom of the bottle, the top of the sleeve is connected to the inner cavity of the bottle, and the bottom end of the sleeve and the top end of the bottleneck are respectively pasted with the barrier film In combination, the bottom of the inner circumference of the bottleneck is connected to a bellows, the bellows faces the top of the bottleneck, the bottom of the bellows is connected to the inner cavity of the bottle, the outer diameter of the top of the bellows is smaller than the inner diameter of the sleeve, the outer diameter of the sleeve is smaller than the inner diameter of the bottleneck, With cutting edge.

Further, the bottom of the inner circumference of the bottleneck extends inward to form a barrier hole, and the bottom end of the corrugated tube is inserted into the barrier hole and is detachably connected to the inner circumference of the bottleneck.

Further, the bottom of the bottle and the barrier film are combined by sticking.

Further, an external thread is arranged on the top of the sleeve, a liquid mixing hole is arranged on the top surface of the inner cavity, and the sleeve is threadedly connected with the liquid mixing hole.

Compared with the prior art, the present invention has the following beneficial effects: 1. When two bottle bodies are used in combination, the bottleneck of the lower bottle body is threadedly connected with the inner cavity of the upper bottle body. When they are close to each other, the sleeve compresses the inside of the bottleneck. When compressed to the maximum distance, the bellows pierces the barrier film at the bottom end of the casing, so that the liquid in the upper bottle flows to the lower bottle to mix with each other, and it is difficult to pierce the barrier film when the compression distance is not enough. Do not make the liquid in the upper bottle flow out of the outer circumference of the lower bottle; 2. The bellows is elastic. When the upper bottle is no longer used, the bellows rebounds, which is convenient to take out the bellows by hand. Use the lower bottle alone for drinking. It will hurt the oral cavity; 3. The upper and lower bottles have the same shape, which is convenient for mold processing, and does not need to be opened separately, and the cost is low; 4. The casing, bottle bottom, and bottleneck are located outside the bottle, so it is easy to stick the barrier film and clean Hygiene; 5. The bottleneck can be sealed with a cap, and an extra layer of barrier film is added to the bottom of the bottle to protect the barrier film at the bottom of the sleeve; 6. The sleeve protrudes from the inner cavity and forms a baffle loop after nesting with the bottleneck to solve The embarrassment of liquid leakage when the upper and lower bottles are screwed together is not tightened.

The above description is only an overview of the technical solution of the present invention. In order to understand the technical means of the present invention more clearly, it can be implemented in accordance with the content of the specification, and in order to make the above and other objectives, features and advantages of the present invention more obvious and understandable. , The following is a detailed description in conjunction with preferred embodiments and accompanying drawings.

detailed description

The specific embodiments of the present invention will be described in detail below with reference to the drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not used to limit the present invention.

In the present invention, if there is no explanation to the contrary, the orientation words used such as "up, down, left, right" usually refer to the directions shown in the drawings of the specification.

Example 1

As shown in Figure 1, a combined bottle set includes a bottleneck 3 with an external thread 33 and a bottle bottom with an inner cavity 2. The inner circumference of the cavity 2 is provided with an internal thread 24, and the top of the cavity faces The bottle bottom mixing hole extends out of the sleeve 21, the top end of the sleeve 21 is connected to the inner cavity of the bottle body 1, the bottom end of the sleeve and the barrier film 22 are bonded by bonding, the top of the bottleneck and the barrier film 31 are bonded by bonding, and the bottom of the inner circumference of the bottleneck 3 Connect the bellows 32, the bellows 32 faces the top of the bottleneck, the surface of the bellows is arranged with an elastic bellows 34, the bottom end of the bellows 32 is connected to the inner cavity of the bottle, the outer diameter of the top of the bellows is smaller than the inner diameter of the sleeve It is smaller than the inner diameter of the bottleneck, the outer circumference of the bottleneck is over-fitted with the inner circumference of the inner cavity, and the top of the bellows has a cutting edge. The cutting edge is an oblique cut of a common straw.
