The utility model is composed of three parts: bottle body, bottle sleeve and bottle cap; the bottle body retains the structure of the original plastic bottle, and the side is the standard external thread of the plastic container; the bottle sleeve is a cylindrical structure, and the middle of the cylinder is a baffle , the inner wall of the cylinder, the lower part of the baffle is the standard internal thread of the plastic container, and the outer wall of the cylinder is a trapezoidal external thread structure with a large helix angle; the shape of the bottle cap is the same as that of the traditional plastic bottle cap, except that the thread inside the cap is the same as The bottle sleeve has a trapezoidal internal thread structure with a large helix angle that matches the thread of the bottle sleeve. The bottle cap is connected to the bottle sleeve, and the bottle sleeve is pressed down on the bottle body. When the bottle sleeve rotates, the baffle of the bottle sleeve seals the opening of the bottle body, thereby The function of sealing the bottle body.

Description

A New Type of Beverage Cap Sealing Mechanism

technical field

The utility model belongs to the field of daily necessities, more precisely, it is a novel beverage bottle cap sealing mechanism.

Background technique

At present, there are many kinds of sealing technologies for bottle caps, and they are becoming more and more perfect, which can well meet the needs of people's daily life. However, there is no multi-vibration field that is specially used in aviation, trains, and fighters on the market. Hold the bottle body and twist the bottle cap with one hand. If there is a sudden vibration at this time, the liquid in the bottle body will easily spill out, which may stain the clothes of the staff in mild cases, or cause mechanical accidents in severe cases; twist the cap It takes a long time to open the beverage bottle in the same way. In such occasions as fighter planes, the staff needs to concentrate for a long time, so the way to twist the bottle cap to open the bottle cap is not suitable for fighter planes.

Contents of the invention

The utility model provides a novel beverage bottle cap sealing mechanism for solving the technical problems of long sealing time and inconvenient sealing in the existing bottle cap sealing mechanism.

In order to solve the problems of the technologies described above, the utility model is realized by adopting the following technical solutions:

A novel beverage bottle cap sealing mechanism, characterized in that the external thread of the bottle body of the novel beverage bottle cap sealing mechanism is the standard external thread of a plastic container, and the internal thread structure of the bottle sleeve is matched with the external thread structure of the bottle body. The external thread structure of the sleeve cooperates with the internal thread structure of the bottle cap.

The bottle sleeve is a cylindrical structure, the material is plastic, the middle of the cylinder is a baffle, the inner side of the cylinder and the lower part of the baffle are plastic container standard internal threads, and the outer side is a trapezoidal cross-section with a large helix angle. thread structure.

The structure of the bottle cap is similar to the traditional bottle cap, the material is plastic, and the inner side of the bottle cap is a trapezoidal cross-section with a large helix angle internal thread structure.

The number of thread matching turns between the bottle body and the bottle sleeve is less than the number of thread matching turns between the bottle cap and the bottle sleeve.

Compared with the prior art, the beneficial effects of the utility model are:

1. A novel beverage bottle cap sealing mechanism described in the utility model adopts the sealing method of two pairs of screw pairs, so that the sealing ability is stronger.

2. A new type of beverage bottle cap sealing mechanism described in the utility model, the bottle cap and the bottle body are relatively moving up and down, and the bottle cap can be closed or opened with one hand.

3. A novel beverage bottle cap sealing mechanism described in the utility model adopts the method of pulling the bottle cap and pressing the bottle cap to seal and unseal, which is convenient and fast, and takes a short time.

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is the main sectional view of the assembly of a novel beverage bottle cap sealing mechanism described in the present invention.

Fig. 2 is a main sectional view of a bottle sleeve part of a novel beverage bottle cap sealing mechanism described in the utility model.

Fig. 3 is a main sectional view of a bottle cap part of a novel beverage bottle cap sealing mechanism described in the utility model.

In the picture: 1. Bottle cap, 2. Bottle sleeve, 3. Bottle body.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail:

As shown in Figure 1, the plastic bottle is divided into three parts, the bottle cap 1, the bottle sleeve 2 and the bottle body 3, the bottle sleeve 2 is set on the bottle cap 1, and the internal thread of the bottle sleeve 2 matches the external thread of the bottle body 3 , the external thread of bottle cover 2 cooperates with the internal thread of bottle cap 3, and the number of thread matching turns of the bottle body and bottle cover is less than the thread matching number of turns of bottle cap and bottle cover.

As shown in Figure 1, the shape of the bottle body is the same as the traditional bottle body, and the outside of the bottle body 3 is the standard external thread of a plastic container.

As shown in FIG. 3 , the shape of the bottle cap 1 is the same as that of a traditional bottle cap, and the internal thread of the bottle cap 1 adopts a trapezoidal cross-section with a large helix angle thread structure.

As shown in Figure 2, the bottle sleeve 2 is a cylindrical structure with a baffle in the middle of the cylinder. The inner side of the cylinder and the lower part of the baffle are the standard external thread of the plastic container, and the outer side of the cylinder is a helical structure with a trapezoidal cross section and a large helix angle.

As shown in Figure 1, the bottle cap 1 and the bottle sleeve 2 are always in a threaded fit state. When the plastic bottle needs to be sealed, the bottle cap 1 and the bottle sleeve 2 are in the maximum separation state at this time, and the bottle sleeve 2 is set on the bottle. The bottle cap 1 is pressed down with the palm of the hand. Due to the cooperation of the inner and outer screw pairs of the bottle cap 2, the bottle cap 2 rotates and moves downward. When the baffle of the bottle cap 2 is in close contact with the opening of the bottle body 3, the bottle cap 1 and the The bottle sleeve 2 is in the minimum separation state, and the plastic bottle is sealed.

As shown in Figure 1, when the plastic bottle needs to be opened, the bottle cap 1 and the bottle sleeve 2 are in the minimum separation state at this time, and the bottle cap 1 is pulled out by hand. Due to the cooperation of the inner and outer screw pairs of the bottle sleeve 2, the bottle sleeve 2 Rotate and move upwards, when the bottle sleeve 2 is separated from the bottle body 3, because the number of thread matching circles between the bottle body 3 and the bottle sleeve 2 is less than that of the bottle cap 1 and the bottle sleeve 2, at this time the bottle cap 1 Still in the thread fit and maximum separation state with the bottle sleeve 2, the plastic bottle is opened.
