Description

Pump vessel

The present invention relates to a pump container, and more specifically, while the volume of the cylinder is reduced by the pressing operation of the discharge nozzle, the contents are discharged to the outside, that is, the pump body is located at the bottom in the container, It is easy to inhale and can be pushed up strongly, that is, pumping force is good, and when pressing is released, the volume of the cylinder is increased to return to its original shape, that is, it consists of a small number of parts, thereby reducing manufacturing cost, It is related to an eco-friendly pump container by not using an iron spring.

A container with a fluid-type household goods widely used in daily life is equipped with a hand-held small pump, so it can be easily used because the contents are discharged out by a certain amount simply by pressing the pump. This pumping device is called a'dispenser', and when the pump is pressed, the contents contained in the chamber inside the pump are discharged through the nozzle. When the force depressing the pump is removed, the contents of the container are sucked into the chamber in the pump while the pump returns to its original shape upward by the elastic force of the spring installed between the container and the pump.

Dispensers such as these are widely used in shampoo containers, and are used to easily discharge and use a certain amount of shampoo solution contained in the shampoo container. In the past, a cap covered with a general lid and having a discharge port through which a shampoo solution is discharged has been used. However, inconvenience such as the need to press the shampoo container has occurred. Due to the structural advantage of preventing the wasting of the solution, it is currently installed and used in most sampu containers.

There is a conventional dispenser 100 (registered room 20-0428943) manufactured for the above purpose. Referring to FIG. 13, a container 20 containing a liquid therein and fixed to an opening side of the container 20 and formed downward, a housing 22 having a negative pressure hole, and a user within the housing 22 Hollow shaft 23, which moves up and down by pressing, a piston 24 connected to the lower portion of the shaft 23 to pressurize or depress the interior of the housing 22, the shaft 23 While communicating with the nozzle head 31 fixed to the upper portion of the shaft 23 and fixed to the upper end of the housing 22 includes a chalet (26) located between the housing 22 and the shaft 23 And, located inside the housing 22, the spring 25, the upper end of which is in contact with the lower end of the piston 24, the shaft 23 and the chalet 26, so that the discharge hole to ensure the outflow of air to be formed It is produced.

Since the conventional dispenser must pull up the contents at the end of the tube 30, that is, the bottom of the tube when pumping, the pumping force is low and the probability of pumping failure is high, especially when the viscosity of the contents is high, the contents are not pumped There is a problem that the output of the soil is deteriorated, and it is difficult to press the button, and the spring 25 of iron is built in the housing 22, so it is always in contact with the liquid inside the container, so the liquid due to corrosion of the spring 25 There is a risk of deterioration, there is a problem that the manufacturing cost is high due to the excessive number of components constituting the dispenser, and the spring and the plastic of the steel are assembled together, and thus there is a problem that the dispenser cannot be recycled when discarded.

The present invention was invented in order to meet the above-mentioned demands of the prior art, the contents of the cylinder is reduced by the pressing operation of the discharge nozzle, the contents are discharged to the outside, that is, the piston and cylinder of the pump body is a container Located at the bottom of the inside, it is easy to inhale the contents, and it can be pushed up strongly, that is, to make the pumping force good, and release the pressing operation so that the volume of the cylinder increases and returns to its original shape.

As the volume is reduced, the check valve 30 inserted into the lower inner periphery of the cylinder 250 is opened to allow the contents to flow into the cylinder 250. As described above, the cosmetic contents or other liquid contents introduced through the space between the plurality of inclined supports 290 flows through the inlet hole 273 and is discharged through the outlet 51 of the discharge nozzle 50. .

When the pressing operation of the discharge nozzle 50 is stopped, it is coupled between the upper flange 231 protruding in a circumferential shape on the upper outer periphery of the lower pipe 230 and the lower flange 241 of the connecting member 240. As the spring portion 264 of the cylindrical spring 260 is expanded, the upper and lower pipes 210 and 230 are raised.

The cylinder 250, the piston 270, the cylindrical spring 260, and the like are made of plastic and are environmentally friendly.

In addition, since the piston 270 and the cylinder 250 of the pump body 200 are located at the bottom in the container 10, suction of the contents is easy, and the contents can be used without leaving.
