Description

Non-metallic pumping device for discharging contents{PUMPING DISPENSER}

In the present invention, all of the component parts are made of synthetic resin made of non-metallic homogeneous material so that the pumping device after use can be directly recycled together with the container without disassembly or disassembly. In particular, the pressure required for the returning of the pumping member is increased even with the synthetic resin elastic body alone. It relates to a non-metallic pumping device for discharging contents that can sufficiently increase the operational stability.

Pumping devices used for discharging contents from containers filled with liquids, gels, creams, etc., have been widely used in various technical fields such as cosmetics, detergents, and shampoos.

In a general pumping device, a pumping part elastically supported by a spring is coupled to a head of a container to which an injection tube is connected, and an opening/closing ball is provided at an inlet inside the stopper, and when the pumping part is pressed, the spring is compressed while the contents inside the head are discharged and the pumping part When the external force to the body is resolved, the pressure inside the head decreases as the pumping part rises and returns by the spring, and the ball closing the inlet is lifted to open and the contents are re-filled in the head.

However, in the conventional pumping device, the spring and the opening/closing ball are made of metal, and the rest of the parts are made of synthetic resin (plastic) material, such as PET. There is a hassle of disassembling or dismantling the device to separate the metal and non-metal parts from each other and discharge them.

Most of them are simply discharging the pumping device together with the container or separately, so the collection company collects the product and additionally separates it for recycling. There is a very inefficient problem because over time is consumed.

Therefore, in recent years, the discharge mechanism of the container including the pumping device is made of synthetic resin made of the same material and the same material as the container, and the need for technology to contribute to environmental preservation by reducing the cost and time required for recycling while convenient for separate collection is emerging.
