Storage container and its liquid injection method

FIELD OF THE INVENTION The present invention relates to a storage container and a method for liquid injection thereof.

In general, a liquid storage container in which a liquid such as lotion, shampoo, detergent, cosmetics, etc. is stored is coupled to the container body in which the liquid is stored, and the container body to discharge the liquid stored in the container body to the outside through a pumping action. made up of means.

As such, the liquid storage container has a problem in that when the liquid stored in the container body is consumed more than a certain amount, all of the liquid remaining inside the container body cannot be used. Therefore, the user throws away the liquid storage container while the liquid remains, or in a state in which the discharging means is separated from the container body in order to use the liquid remaining in the container body, overturn the container body and apply an impact to the container body A method of discharging the liquid remaining inside the body to the outside was used.

However, in this case, there is a problem in that the method for using the remaining liquid as well as generating environmental pollution is inconvenient.

Therefore, in the prior art, in order to solve the above problems, a balloon-type liquid storage container made of a stretchable material has been developed.

As the flexible balloon-type liquid storage container is contracted in response to the consumption of the liquid and is configured to continuously compress the internal space in which the liquid is stored by the elastic force, the liquid stored in the container can be used until the end.

As such, the conventional liquid storage container includes an outer case, a tube of an elastic material that is accommodated inside the outer case to store a liquid therein, a valve coupled to the upper end of the tube to close the inlet of the tube, and a valve It is communicated with the inside of the tube through the tube, and consists of a pump configured to discharge the liquid stored in the tube to the outside by performing a pumping action.

On the other hand, the tube made of an elastic material has a property of self-contracting when the liquid is stored therein due to its own elastic force and is expanded.

Therefore, in the prior art, when the liquid is injected into the tube, the liquid is injected into the tube in a state in which the tube is expanded using negative pressure so that the tube is contracted and the liquid stored therein is not discharged to the outside, and a valve is placed on the top of the tube. After bonding, the negative pressure was released.

However, in this case, equipment for applying/releasing the negative pressure to the tube is additionally required, and the overall process time is increased, so there is a problem that productivity is lowered as well as cost is increased.

In addition, in order to solve the above-mentioned problem, in the prior art, a method of injecting liquid into the tube by inserting a nozzle for supplying a liquid into the incision groove in a state in which a valve having an incision groove is previously coupled to the upper end of the tube was used.

However, in this case, the nozzle penetrates the valve through the incision groove and is inserted into the tube, or in the process of being separated from the valve after injecting the liquid, the valve does not fully adhere to the tube, so that a part of the incision groove is opened. There was a problem in that the liquid leaked into a part of the open incision groove. In addition, after the nozzle is coupled to the valve or separated from the valve, there is a problem in that a post-process must be performed to remove the liquid leaked to the upper end of the valve.

The present invention has been devised to solve the above problems, and an object of the present invention is not to cut in advance the valve coupled to the opening of the tube, but to cut the valve when the liquid injection nozzle is inserted into the tube, so that the valve is connected to the liquid injection nozzle.

The tube body 111 is formed of an elastic material that can be expanded or contracted to accommodate a liquid therein. For example, the tube body 111 includes a first body portion extended from the engaging portions 112 and 113 and supported on the neck of the ring body 131 , and a container of the ring body 131 extending from the first body portion. It is accommodated in the, and may include a second body portion formed with a relatively thicker thickness than the first body portion. As the second body portion is formed to have a greater thickness than the first body portion, durability is improved to prevent bursting due to internal pressure during expansion, and to prevent a decrease in elasticity even when inflated for a long time.

The engaging portions 112 and 113 may extend from the upper end of the tube body 111 in the radial direction of the tube body 111 to be caught and supported by the neck of the ring body 131 .

When done, the elastic membrane 121 is compressed on the inner surface of the tube body 111 to close the opening O of the tube 110 .

In addition, the elastic film 121 may be formed in a structure in which the size of the inner diameter gradually decreases along the protruding direction. Specifically, the elastic film 121 may be formed in a hemispherical shape.

Through this, since the pressure of the liquid applied to the surface of the elastic film 121 is evenly distributed along the surface of the protruding elastic film 121 without being concentrated on any one part, the elastic film 121 is formed by the liquid injection nozzle 200 . ), the pressure of the liquid is not concentrated on the incised part, but acts evenly around the elastic membrane 121 so that the incised part can be perfectly adhered.
