Pump Type Cosmetic Container {Pump Type Cosmetic Container}

The present invention relates to a pump-type cosmetic container that discharges the contents filled by a pumping operation to store various liquid contents, and more particularly, to a pump-type cosmetic container that simplifies the structure for the pumping operation and enables quantitative dispensing while ensuring good assembly. It relates to a pump-type cosmetic container that can secure stability and increase operational reliability.

In general, a pump-type container called a dispenser is widely used as a container containing liquid or viscous household items, which allows users to press the contents with their hands and discharge a certain amount of the contents. In the case of a gel or liquid with a low viscosity of 0.01 to 6 poise, the content contained in the container body is suctioned by receiving a predetermined pressing operation from the user to enable convenient use and quantitative discharge. A pumping cosmetic container equipped with a pumping mechanism on the inlet side of the container body to be discharged is widely used.

In addition, the pumping cosmetic container has a container body that forms an accommodation space therein to accommodate and store the contents, and is assembled to the open upper side of the container body to receive a pressurizing operation force from the user and to perform an upward and downward interlocking operation on the body. It consists of a pumping mechanism that sucks in the contents accommodated inside and discharges them to the outside, and the container body is a receiving element having an inlet on the upper side and a tubular shape for storing the contents inside, synthetic resin material, metal material, or glass material. In addition, it can be provided in the form of tubing the laminate sheet in a cylindrical shape.

In addition, the pumping mechanism includes a housing forming an outer body coupled to the inlet side of the body, and a button provided at an upper center of the housing to be able to move up and down to receive a pressing operation from a user and having a discharge port for discharging contents to the outside at one side. And, a piston tube connected to the lower part of the button to receive the contents and guide it to the discharge port, and provided to be lifted integrally with the button, and the button tube is slidably inserted into the inside, filling the inside of the body with the lower part A cylinder to which a suction pipe for sucking the contents is connected, and a lower end supported on one side of the inside of the housing by returning the button pressed by the pressing operation to surround the button pipe, thereby providing a lifting support force for the button. It consists of a return spring that acts on

When a button is pressed with a finger in the cosmetic container of the pumping type having this configuration, a vacuum pressure is generated inside the container body by the pressure, and the contents stored in the container body are sucked in at a certain amount by this vacuum pressure, and the contents stored in the container body are sucked into the side of the container body. It is discharged to the outside through the discharge port formed in the.

However, in the cosmetic container of the conventional pumping method, when a user presses a button, the contents are discharged relatively far as a high pumping force is initially applied, but at the end of the pressing force applied to the button, the contents are discharged as the pumping force is lowered. There is a disadvantage of not being able to discharge far. As a result, there is a disadvantage in that the contents flow down and become messy on the outer surface of the container body positioned below and around the discharge port.

In order to solve this problem, conventionally protrudes around the discharge port or has a discharge pipe in the form of a straw at the discharge port, but there is a serious disadvantage in that it is difficult to upgrade the cosmetic container as the freedom of design of the container is extremely inhibited.
