Description

Pump type container

The present invention relates to a pump container, and more particularly, a pump container that can be used by pumping liquid contents, and a wet type that can replace the metal spring inside the container so that pumping is made by pressing and returning the nozzle cap. Alternatively, by applying an elastic body molded in a high-density or low-density sponge-type foaming method through dry, etc., the pumping operation is performed while taking advantage of the sufficient elasticity of the metal spring. It relates to a pump container that can reflect a high recyclability grade.

In general, a container for storing contents therein is generally composed of a container body for accommodating the contents, and a lid covering the container body.

However, when liquid contents such as food, medicine, and cosmetics are put in such a container and used, a pump container has been developed to compensate for the disadvantage that the contents are easily contaminated because the lid is opened and the cosmetic contents are taken by hand.

In general, a pump container is a device for discharging a liquid content having a viscosity of 1 cps to 100,000 cps contained in the container body by a fixed amount, and by pressing a button including a nozzle part, the user can take the desired amount of content and , since the contents come out only through the outlet, it is possible to prevent the contents from being contaminated by minimizing contact with pollutants. In addition, the pump container is always discharged in a certain amount according to the pressing operation of pressing the button, thereby preventing wastage of the contents.

Looking at the technology of the source for the pump container, there has been devised a nozzle for discharging the contents of a pump-type container, which is No. 20-0383083 for registration office, which includes a body having a hollow interior; An opening and closing membrane formed integrally with the body is included on the front end of the body by a connecting piece integrally extended with the inner portion of the body, and the outer cylinder with a hollow fitting portion is formed in the outer side of the body by fitting more In addition, the opening and closing membrane connected to the body and the front end of the body is characterized in that it is formed in any one shape of a circle, a square, a pentagon, a hexagon, and an octagon.

This prior art is provided on the upper end of the pump-type container and fitted into the spray nozzle through which the contents in the container are discharged, so that the remainder of the discharged contents is not exposed to the outside, and external air is introduced into the container. By blocking this, not only solves the problem of deterioration and discoloration of the contents of the container, but also does not feel burden on the production cost due to the simple configuration, and since it can be used directly by inserting it into the used pump type container, the container can be used. It can be made separately or reused by using up the contents of the container and inserting it into another container that has been replaced.

On the other hand, as another example of the seafarer technology, a button retractable cosmetic container, which is disclosed in Korean Patent Publication No. 10-2020-0085505, has been devised, which includes a container body in which the contents are accommodated; a pump unit disposed on the upper portion of the container body to discharge the contents to the outside through a pumping operation; and a button part disposed on the upper side of the pump part so that the pumping operation is performed according to the user's pressurization and depressurization, and provided with a discharge part for discharging the contents to the outside, and the discharge part and the discharge part inside the button part Doedoe communication, the volume is decreased and increased according to the pressurization and release of the pressure on the button part, so that a suction space for sucking the contents remaining inside the discharge part can be formed to supply the contents in the container.

The above two types of containers are conventional technologies that apply pump containers, and for smooth pumping operation, the spring applied together with the structure of each piston and check valve inside is a metal material. When it is separated into a waste container and thrown away, since it is difficult to separate the spring provided therein, the disadvantage that the recyclability grade is always applied to a low grade is pointed out.

Recently, recycling grades for the recyclability of products are being given, and in the case of grade 1, the standard for recycling ease of 1st grade is higher than 48% even for waste containers whose contents have been consumed as the best or excellent depending on the ease of recycling. It is applied, and recycling is difficult from grade 2 or lower.

Accordingly, efforts are being made to use a container made of a material having a high recyclability grade in terms of resources and the environment, and recyclability technology is required.
