Description

Sanitary bottle cap structure with a lot of liquid during use and no liquid leakage when poured

technical field

The utility model relates to the technical field of bottle caps, in particular to a hygienic bottle cap structure with a large amount of liquid during use and no liquid leakage when poured.

Background technique

In daily life, containers for containing liquid substances can be seen everywhere, such as beverages, laundry detergents, shower gels, etc. A bottle is a type of container, in addition to the bottle itself, the cap is a key component to ensure the sealing performance.

Bottle caps vary widely according to their function and purpose, but beverage bottle caps are relatively simple. Common beverage bottle caps are roughly divided into two types, one is a style with a large open mouth after unscrewing directly, and the other is a style with a small mouth that can be sucked after being unscrewed. Now on the market, most of them use a large open style. This style of bottle requires two hands to unscrew before drinking, such as an ordinary mineral water bottle. However, this style must be re-screwed after drinking to prevent The liquid leaks out, and even after screwing on, there will still be a gap between the screwed threads. The liquid leaks out along the thread gap, and the sealing performance is not particularly good; the most important thing is that during the drinking process after unscrewing, If it is accidentally knocked down, the liquid inside will flow out in large quantities, which will not only cause waste, but also flow into the corresponding external environment such as people or desks, making people scrambling to deal with it, and the experience is very bad.

The other is the small mouth style that can be sucked. This design uses less liquid to drink at one time when drinking, which is very unpleasant for thirsty people. The same disadvantages as large exposure. There is a kind of bottle cap on the market. Its structure is: a film is arranged on the small mouth channel, and a cross-shaped gap is opened on the film. Using the principle of liquid tension, when the bottle is knocked down, the liquid will not easily overflow from the cross-shaped gap, even if it overflows. There is also only a small amount of liquid.

Therefore, the applicant has designed a hygienic bottle cap structure with a large amount of liquid during use and no liquid leakage when poured, so that it has both the advantages of large opening and no flow out after being knocked down, that is, it can drink water in large gulps and can also No liquid came out after being knocked down again. And to make the whole design simple and easy to produce, it seems very practical.

Utility model content

The purpose of the utility model is to overcome the shortcomings of the prior art, and to provide a hygienic bottle cap structure with large opening and anti-leakage, which has a large amount of liquid during use and no liquid leakage when poured.

The lower end of the drinking head is provided with a lower resisting piece, and the lower resisting piece is set at the mouth of the bottle body;

The upper end of the drinking head is provided with an upper resisting piece, a through hole A is opened on the upper resisting piece, and a through hole B is opened on the lower resisting piece, and the through hole A and the through hole B allow the liquid to flow along the liquid channel;

A sealing member and an elastic member are arranged in the liquid channel. The upper and lower ends of the elastic member are respectively in contact with the lower surface of the upper resisting member and the upper surface of the sealing member. The sealing member is movably arranged in the liquid channel to realize the opening and closing of the through hole B. The peripheral edge of the seal and the liquid channel have clearances.

Further, the sealing member is in the shape of a sheet, and the circumferential direction of the sheet-shaped sealing member is designed with an integral support foot, the support foot is in contact with the inner wall of the liquid channel, and the circumferential edge of the sealing member, the support foot and the inner wall of the liquid channel form a gap, and the seal is sealed. The parts are provided with air holes that pass through up and down.

The sealing member is conical, the diameter of the cone-shaped sealing member is larger than the diameter of the through hole B but smaller than the diameter of the liquid passage, and the sealing member is provided with air holes that pass through up and down.

Further, the upper end of the elastic piece is fixedly connected with the upper resisting piece, and the lower end thereof is fixedly connected with the lower resisting piece; or the upper end of the elastic piece is set in separate contact with the upper resisting piece, and the lower end of the elastic piece is set in separate contact with the lower resisting piece; or The upper end of the elastic piece is arranged in contact with the upper resisting piece, and the lower end of the elastic piece is fixedly connected with the lower resisting piece;

Preferably, the elastic member is a spring.

Further, the upper resisting piece, the drinking head and the lower resisting piece are separated; or the upper resisting piece, the drinking head and the lower resisting piece are integrated; or the upper resisting piece and the drinking head are integrated, The lower stopper is separate; or the lower stopper and the drinking head are integrated, and the upper stopper is separate.

Further, the mouth of the bottle body is connected with the lower resisting member; or the mouth of the bottle body is connected with the drinking head.

The upper end of the drinking head is also provided with a top cover, and the top cover and the drinking head are matched in a threaded connection, or the top cover is hinged on the outer surface of the drinking head in a flipping manner, or the top cover is directly inserted into the through hole A to achieve sealing.

The utility model has the following advantages:

(1) By opening a through hole B on the lower resisting member, and arranging a sealing member and an elastic member in the liquid channel, when drinking, under the pressure of squeezing or suction by the mouth, the sealing member and the through hole B are kept away to realize opening. When drinking, even if it is knocked down, under the action of the spring force of the elastic member, the sealing member will still close the through hole B and will not leak;

(2) When the liquid is flowing, it flows through the through hole B, the gap and the liquid channel in sequence from the bottle, and finally flows out from the through hole A. The size of the flow rate can be designed according to the needs of different through holes B, gaps, liquid channels and through holes A. size, to ensure that the amount of drinking is similar to that of the open mouth, that is, it can be drunk in large quantities, and it has the advantages of pouring without leakage and being able to drink in large gulps;

(3) When the top cover is removed, there is no need to unscrew it with two hands to drink water. You can drink water by squeezing with one hand or sucking with your mouth. It can be very convenient to drink in office or driving situations;

(4) In the traditional large open mouth style, after drinking, part of the water in the mouth will flow back into the bottle, which is very unsanitary. In this scheme, when the mouth is released or not squeezed after drinking, the water in the mouth will not flow. If the water flows back from the mouth, it will be blocked by the outer ring of the upper resist and will not reach the position of the through hole A, so the water in the mouth will not flow into the bottle again;

(5) In the traditional large-opening style, when drinking water, it cannot be stopped in time, and it may be choked. However, this solution can be stopped by loosening the mouth or stopping squeezing, and it is not easy to be choked.
