Pump assembly and container with content discharge function

Abstract

The invention aims to provide a pump assembly and a container with a content discharge function. The pump assembly is suitable for being mounted on a container body, and comprises a pump main body anda pressure rod, wherein the pressure rod is provided with a rod body and a piston part; the pump main body is provided with a first cavity; the rod body can be arranged in the first cavity in a sliding mode in a penetrating mode, and one end of the rod body extends out of the first cavity; the piston part is connected onto the rod body, and is positioned in the first cavity for dividing the firstcavity into a first gas cavity and a second gas cavity; and the first gas cavity and / or the second gas cavity is a sealing cavity. The piston part can rebound under action of resultant force of gas pressure in the first gas cavity and gas pressure in the second gas cavity to drive the rod body to rebound, so that the pump main body does not need to equip with the spring for enabling the rod bodyto rebound, and therefore, the pump assembly can be completely made of a plastic material, a metal material is not mixed, and the pump assembly is easily recycled. The container with the content discharge function comprises the pump assembly.

Description

technical field [0001] The invention relates to a pump assembly and a container with the function of discharging contents. Background technique [0002] Containers with a content discharge function are often used in daily life, such as bottles for cosmetics, shampoos, detergents or medicines. The container with contents discharge function includes a container body, a pump assembly, a head cap and an extension tube. [0003] The container body has a liquid filling port for adding content; the pump assembly includes a pump body and a pressure rod, the pump body is detachably penetrated in the liquid filling port, the pressure rod is installed on the pump body, and the upper end protrudes from the pump The main body and the head cap are installed on the upper end of the depression bar. One end of the extension tube is connected to the pump body, and the other end extends below the liquid level of the contents. [0004] The head cap is used to be pressed by the user to drive ...

Problems solved by technology

The garbage recycling standards of most countries require plastics and metals to be recycled separately. However, when the above-mentioned pump components are recycled as garbage, since the springs are tightly installed inside the pump body, it is difficult to take them out. As a result, the pump components in the prior art are not easy to recycle. Can be discarded as waste
