Pressing type bottle cap capable of adjusting liquid discharge amount

Abstract

The invention discloses a pressing type bottle cap capable of adjusting a liquid discharge amount. The pressing type bottle cap comprises a bottle cap body and a pressing tube, wherein the bottle cap body comprises a guide column, an outer barrel and an inner barrel, the guide column is used for guiding the pressing tube to slide, and the outer barrel and the inner barrel are integrally formed and coaxially arranged outside the guide column; the inner circular face of the outer barrel is provided with an inner thread connected with a bottle opening; the inner barrel serving as a piston barrel is matched with a piston fixedly connected to the lower end of the pressing tube, the bottom surface of the inner barrel is provided with a liquid inlet valve allowing liquid to flow in, a liquid discharge valve allowing the liquid to flow from the inner cavity of the inner barrel into the pressing tube is arranged in the pressing tube, a return spring is arranged between the piston and a lower cap bottom surface, a limit ring for limiting the upward sliding of the pressing tube is connected to the tube wall, located below the guide column, of the pressing tube through a thread pair, and circumferential limiting is achieved through concave-convex coordination when the top surface of the limit ring is abutted against the bottom surface of the guide column. The pressing type bottle cap has the advantages that the liquid discharge amount can be regulated according user's needs, use convenience is achieved, and waste is avoided.

Description

technical field [0001] The invention relates to a push-type bottle cap, in particular to a push-type bottle cap with adjustable liquid extrusion. Background technique [0002] 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,...

Problems solved by technology

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; Repacking in the bottle body is not only unhygienic, but also causes the material components in the bottle to deteriorate, which is not worth the candle
