The present invention relates to a dispenser, and more specifically, by rotating the dispenser for dispensing a certain amount of cosmetics by simply rotating the dispenser at a predetermined angle to prevent the contents from being discharged due to unnecessary malfunctions, and to prevent foreign substances from entering into the dispenser or the sealed container. It relates to a dispenser having a locking structure of the upper and lower stages to prevent the inflow.

In general, a dispenser is a device that is connected to the bent portion of a sealed container filled with gas, liquid or other contents to eject and use the contents by a predetermined amount, and stores cosmetics, perfumes, medicines, foods, etc. It is well known that it is applied to various sealed containers.

Such a dispenser is usually coupled to the upper end of the sealed container, the lower end of the cylinder is formed with a suction port; A check valve configured to control the inflow of contents through the inlet; A piston coupled to the inside of the cylinder and configured to discharge contents at the same time as a vertical pump operation; A pump stem coupled to an upper side of the piston and configured to eject contents along a flow path; A sealing coupled between the pump stem and the piston to control discharge of contents when the pump is operated; A spring coupled between a lower end of the piston and a check valve to maintain operation of the piston; A button coupled to an upper end of the pump stem and configured to discharge contents through a nozzle and press the upper end to pump the piston up and down; And a cylinder cap formed at the center thereof, the cylinder cap being coupled to the bent portion of the sealed container in a state including the outer edge of the cylinder. Is done.

Therefore, when the button is pressed by the user while the dispenser is coupled to the bent portion of the sealed container, the contents introduced into the cylinder are pressurized by the pump actuating the pump stem, the piston and the seal lowered at the lower side thereof, and at the same time The seal closing the piston is opened so that the contents are discharged therebetween.

However, all the pumping means of the conventional dispenser are formed so that the contents are discharged at the same time as the button is pressed, and the contents are discharged by the same action even if the buttons are pressed by unnecessary malfunction or external pressure.

That is, as the pumping means such as the pump stem, the piston, and the sealing, including the button are formed to be always in operation, it is not possible to prevent the loss of the contents due to a malfunction. Not only a lot of contents are lost, but when the user presses a button by an external pressure when carrying it on a trip, the contents are not only released but also various inconveniences such as contacting the surrounding clothing or other belongings are caused.

Meanwhile, in order to solve the above problem, as shown in FIG. 1, the male threaded portion 86 is formed on the upper side of the coupling hole 84 of the button 80, and the female threaded portion is formed on the upper bent portion of the cylinder 20 corresponding thereto. A technique has been proposed for forming the portion 24 to be mutually screwed together.

However, according to such a configuration, in addition to the inconvenience of having to turn the button 80 at all times in order to lock the dispenser 10, a certain amount of contents are discharged when the button 80 is pressed to lock the loss.

Furthermore, a gap is generated between the lower outer surface of the coupling hole 84 of the upper and lower buttons 80 and the female screw portion 24 formed at the upper portion of the cylinder 20, whereby foreign matter penetrates therebetween, thereby allowing the interior of the cylinder 20 to enter. And contaminate the inside of the cylinder, and also cause various problems.

In addition, when water is used in the female threaded portion 24 formed in the upper portion of the cylinder 20 in a state of stagnation, the water is introduced into the cylinder and the sealed container by taking the outer surface of the pump stem 50 into the concentration of the contents. Many problems occur, such as diluting the bar, an urgent improvement is required.

The present invention is devised to solve the above problems, the main purpose of the present invention is to form a locking structure for preventing the contents from being discharged by unnecessary malfunction of the dispenser, but the relationship with the pump stem coupled to the top of the cylinder It is to provide a dispenser having a locking structure of the upper and lower stages that can be selectively used by turning the button to rotate the pump stem at an angle to lock or open the pump operation.

Furthermore, it is to provide a dispenser having a locking structure of upper and lower stages which rotates the pump stem to lock the operation of the dispenser, but locks the button in a protruding or pressed state according to a user's selection.

Another object of the present invention is the upper and lower two stages to prevent foreign matter from penetrating between the inner surface of the upper end of the cylinder and the outer surface of the pump stem which is operated up and down in the cylinder or the outer surface of the bottom of the button coupled to the upper end of the pump stem during operation of the dispenser.
