Description

Dispensing closure with self-closing valve {DISPENSING CLOSURE HAVING AUTOMATIC SEALING VALVE}

The present invention relates to a dispensing closer equipped with an automatic closing valve. More specifically, the soft automatic valve is fastened to the fastening ring portion, and the valve portion coupled to the fastening ring portion to the nut is placed on the inside of the closer body coupled to the inlet. It relates to a dispensing closer equipped with an automatically closing valve that is opened by the pressure of the contents when the contents stored in the container are fastened and discharged through the automatic valve.

Generally, a dispenser type container is used by attaching a dispenser to the upper side of a closed container filled with gas, liquid, or other contents and ejecting the contents in a certain amount through a pressurizing operation.

A conventional dispenser container includes a container body that holds the contents, a pump that is connected to the upper part of the container body and creates a vacuum inside the container body to raise the contents through a pumping action, and a pump located at the top of the pump that raises the contents according to the user's pressure. It descends and consists of a button that transmits pressure to the pump. And when the user presses the button, the pump's pumping action is achieved and the contents are discharged.

However, the conventional dispenser container had a problem in that when carrying the container, pressure was applied to the button without the user's intention, causing unnecessary discharge of the contents.

In order to overcome these problems with conventional dispenser containers, a 'retractable cosmetic container', which is configured so that the button is exposed to the outside only when the user wants to use the contents, was developed in Republic of Korea Registered Utility Model No. 20-0347811 (hereinafter referred to as 'Patent Document 1') ').

Referring to Patent Document 1, there is a container that discharges the contents stored in the container according to the pressing operation of the button, and the guide protrusion of the pump body located in the guide hole of the external container located outside the container follows the spiral groove of the rotating pipe body. In a cosmetic container in which a button mounted on the pump body emerges from the rotating pipe body while being guided, a guide pipe body having spiral grooves on both sides is undercut mounted on the upper part of the outer container, and a pump body is formed in the spiral groove of the guide pipe body. The guide protrusion is through-coupled, and a rotary tube forming vertical guide grooves on both sides of the inner surface where the end of the guide protrusion of the pump body penetrating the spiral groove of the guide tube body is located is covered with the outside of the guide tube body and is undercut mounted, A configuration is provided in which a button is mounted on the stem of the pump body.

The conventional button-emerging cosmetic container according to Patent Document 1 has a structure in which the container accommodated in the external container is raised and lowered together in the process of the button being raised and lowered. This double container structure not only causes an increase in the unit price of the product, but also causes problems such as product defects such as detaching of the container due to the weight of the container in which the contents are stored if the container is dropped due to the user's carelessness while the container is in an elevated state.

In addition, after the contents are discharged by pressing the button, the contents remain at the tip of the nozzle of the button, causing a problem in that the contents remaining at the tip of the nozzle leak or flow to the outside and contaminate the container. Additionally, there was a problem in which the contents deteriorated due to contact with air or the nozzle was blocked due to the contents hardening while remaining at the tip of the nozzle, making it difficult to discharge the contents smoothly.
