Description

Adjustable push-on bottle cap

technical field

The invention relates to a push-type bottle cap, in particular to an adjustable push-type bottle cap.

Background technique

All kinds of liquid substances that people need in life, such as wine, beverages, oil and other liquid substances, as well as many cosmetics such as shampoo, shower gel, detergent and other gel state substances, all need to be filled in various bottles In body devices, push-type bottle caps are widely used in containers containing the above-mentioned liquid substances. When these substances are needed, the pressing tube on the bottle cap can be squeezed hard to press the liquid or semi-gel state substances from the bottle body. out. Among them, the most problem that people encounter is that they cannot control the amount of the pressed substance, sometimes with a little force, the substance will be poured out more than the required amount, resulting in waste; The amount can never meet your own needs, which requires heavy pressing several times. In a hurry, it is inevitable that the amount pressed out will be more than the required amount, which will cause greater waste; Putting back in the bottle again is not only unhygienic, but also causes the material components in the bottle to deteriorate, which is not worth the candle.

Therefore, the present invention needs to start from the actual needs of consumers, and can satisfy the crowd of various demand levels. People can increase or decrease the amount of material flowing out of the bottle according to actual needs, only by increasing or decreasing the pressure when pressing, to achieve purpose of effective control. While satisfying different levels of consumer groups, it can reduce consumers' living consumption costs and change people's life concepts.

Contents of the invention

In view of this, the purpose of the present invention is to overcome the defects in the prior art and provide an adjustable push-type bottle cap, which can adjust the amount of liquid pressed out of the bottle according to the user's needs, thereby facilitating use. Prevent wastage.

The adjustable push-type bottle cap of the present invention includes an upper cover, a lower cover and a pressing tube; the upper cover is a cylindrical structure, and the lower cover includes an inner cylinder and an outer cylinder that are coaxially arranged and integrally formed. The inner circular surface of the outer cylinder is provided with an internal thread for connecting with the bottle mouth; the inner circular surface of the inner cylinder is matched with the outer circular surface of the upper cover through a thread pair, and the bottom of the upper cover is connected with the lower cover. A piston barrel is formed between the bottom surfaces of the piston barrel, and a piston is arranged in the piston barrel. The pressing tube passes through the upper cover in an axially slidable manner and is fixed with the piston. The bottom surface of the inner barrel of the lower cover A liquid inlet valve is provided to allow the liquid to flow into the piston cylinder, a liquid discharge valve is provided on the bottom surface of the piston to allow the liquid to flow from the piston cylinder to the pressing tube, and a return spring is provided between the piston and the bottom surface of the inner cylinder;

Further, a limiting ring is provided on the tube wall of the pressing tube below the upper cover, and the limiting ring is used to limit the upward sliding of the pressing tube;

Further, a suction pipe is connected to the bottom of the lower cover, and the liquid in the bottle is sequentially sucked into the piston cylinder through the suction pipe and the liquid inlet valve;

Further, a scale is arranged axially on the outer surface of the upper cover;

Further, the pressing tube is an L-shaped structure.

The beneficial effects of the present invention are: the adjustable push-type bottle cap of the present invention is connected to the bottle mouth through the internal thread on the outer cylinder of the lower cap, and the upper cap is matched with the lower cap through a thread pair, therefore, the upper cap can be adjusted by rotating the upper cap. The height of the cover relative to the lower cover, due to the sliding fit of the pressing tube and the upper cover, and the piston is fixed at the lower end of the pressing tube, therefore, when adjusting the height of the upper cover, the maximum height of the piston can be controlled, thereby controlling the stroke of the piston, and finally achieving control The amount of liquid pressed out by the piston. In the present invention, when the piston is driven downward by the pressing tube, the liquid in the inner cylinder enters the pressing tube through the drain valve and flows out from the pressing tube until the piston goes down to the bottom of the inner cylinder of the lower cover. In contrast, the pressing tube is released, and the piston moves upward under the action of the return spring, and the liquid in the bottle is sucked into the piston barrel from the liquid inlet valve.
