Embodiment Construction

[0008] As shown in the figure, the elastic outlet air pressure valve A and the elastic inlet air pressure valve C are both made of elastic materials such as rubber. And juxtaposed into one. And be squeezed between the bottle body D and the bottle cap B. Thereby the bottleneck is closed, and only two one-way valves A and C are connected with the outside world. The lower end of the elastic outlet air pressure valve A is connected with a conduit E, and stretches to the bottom of the bottle.

[0009] The openings of the check valves A and C are flat, so they are normally closed. When the air pressure inside and outside the bottle is not equal, due to their own elasticity, their flat openings can be opened by the fluid from the larger flow section to the smaller flow section under the action of higher air pressure. . On the contrary, it is more tightly closed. Therefore, the A valve can only conduct to the outside of the bottle, and the C valve can only conduct to the inside o...

Abstract

Disclosed is a hand-extrusion pumping magma packing bottle, belonging to the field of packing container. The liquid in the bottle can be tapped off with a single hand and without inverting the bottle. And no liquid flows out when the bottleneck is re-closed. The bottleneck is equipped with parallel elastic leading-out air pressure valve and the elastic leading-in air pressure valve, which form a pump operated by hand, the pump leading the liquid in bottle out continuously.

Description

technical field [0001] The invention belongs to the field of packaging containers. Background technique [0002] Viscous liquids, such as shower gel, shampoo, oil, etc., are not easy to pour out because they adhere to the bottom of the container when they are about to be used up. Although the hand-pumped thick liquid packaging container recently appeared on the market can overcome the above-mentioned shortcomings, when it is closed again, liquid will be discharged. And after leaving the support surface, both hands are required to operate. In addition, the structure is complex and the cost is too high. Contents of the invention [0003] The purpose of the present invention is to design a pump-type liquid packaging container that can suck in gas and discharge liquid by squeezing the bottle body with resilience. [0004] The present invention is achieved in the following way: at the bottle mouth, two normally closed elastic air pressure valves that can only conduct in one ...
