Description

Pumped container with contents suction structure

The present invention relates to a pump-type container having a contents suction structure, and more particularly to the contents remaining at the distal end of the discharge port as the inner volume of the button member is changed by the change in the shape of the contents suction portion according to the pressing of the button member. By integrating the suck-back action to inhale, the contents can be prevented from sticking to the outlet through a simple structure, and the contents suction structure can prevent contamination of the container due to leakage of contents. It relates to a pumped container provided.

In general, the pump-type container is composed of a container body for storing the contents, and a pumping member coupled to the upper portion of the container body, and discharges the contents stored in the container body to the outside by the pumping action according to the pressing of the button portion.

In the pumped container as described above, after the ejection of the contents is performed by pressing the button portion, the contents remain at the tip of the nozzle of the button, and the contents remaining at the tip of the nozzle flow down to cause contamination of the container as well as air. In contact with and deteriorate.

In addition, since the contents remaining at the tip of the nozzle harden to close the nozzle and the discharge is not performed smoothly, the contents fixed at the tip of the nozzle should be removed and the contents should be ejected for the next use. Of course, there was a problem that results in unnecessary waste of the contents.

Pumping containers for solving the above problems are registered Patent Nos. 10-1219011 (hereinafter referred to as 'Patent Document 1') and Registered Patent Nos. 10-1265948 (hereinafter referred to as 'Patent Document 2'. ) Is disclosed.

The patent document 1 is characterized in that the guide member provides a piston function when the button body moves in the upward direction to suck the contents remaining in the nozzle, thereby minimizing the remaining amount of the contents remaining in the nozzle.

On the other hand, Patent Document 2, after the pumping action using a double spring, by re-suctioning the contents remaining in the moving passage in response to the control protrusion presses the locking protrusion, to minimize the residual amount of the contents remaining in the moving passage It is characterized by being configured to be.

However, both of the patent documents 1 and 2 have a very complicated structure for suctioning the contents remaining at the tip of the nozzle, so that not only productivity is lowered by increasing the assembly time due to the addition of parts, but also the cost of the container is increased. There was a problem.

The present invention has been made to solve the above-mentioned problems, an object of the present invention is to suck the contents remaining in the tip end of the discharge port as the volume of the button member is changed by the change in the shape of the contents suction portion according to the pressing of the button member By configuring the Suck-back action, not only the contents can be prevented from sticking to the discharge port through a simple structure, but also the contents suction structure capable of preventing contamination of the container due to leakage of contents is provided. It is to provide a pumped container.

In order to solve the above problems, the pump-type container having the contents suction structure according to the present invention includes a container main body in which the contents are stored and the contents stored in the container main body by a pumping action located on the upper part of the container main body. A pumping member for discharging to the outside; In the pumping type container comprising a; button member which is located on the pumping member to press the pumping member, the discharge port is provided on one side thereof;

Between the pumping member and the button member is provided with an elastic material suction portion that changes its shape depending on whether the button member is pressed and changes the volume of the inner space of the button member. Due to the contraction of the part, the volume of the inner space of the button member is reduced, and when the pressure of the button member is released, the contents suction part is restored, and the contents remaining at the tip of the discharge port as the volume of the inner space of the button member increases. It is characterized in that it is configured to be inhaled.

In addition, the central portion of the contents suction portion is characterized in that the communication pipe for communicating the pumping member and the discharge port is provided so that the contents moving upward through the pumping action of the pumping member can be moved to the discharge port.

In addition, a seating jaw supporting the lower end of the button member is formed below the outer circumferential surface of the contents suction part.

In addition, the inner side of the button member is provided with a coupling portion coupled to the contents suction portion, the contents suction portion is characterized in that it is formed in close contact with the inner peripheral surface of the coupling portion to block the leakage of the contents.

In addition, a seating jaw in which the engaging portion of the button member is formed is formed below the outer circumferential surface of the contents suction part.

As described above, according to the present invention, as the inner volume of the button member changes due to the change in the shape of the contents suction part according to whether the button member is pressed, a suck-back action is performed to suck the contents remaining at the tip end of the discharge port. By constructing, it is possible not only to prevent the phenomenon of the contents sticking to the discharge port through a simple structure, there is an advantage that can prevent the contamination of the container due to leakage of the contents.

In addition, by making the suck-back action easily through the contents suction portion of the elastic material, not only can the productivity be improved by shortening the assembly time due to the reduction of the number of parts, but also can be applied to various button structures. There is an advantage.
