Description

Container for spraying liquid {CONTAINER FOR SPRAYING LIQUID}

The present invention relates to a container for liquid injection with an improved passage structure through which contents are discharged.

In a cosmetic container or the like, a pump is coupled to an upper entrance of a container for storing liquid contents such as perfume and the like, and functions to discharge and spray a fixed quantity of contents to the outside. When the user presses the nozzle corresponding to the button downward to spray the liquid content, the content flowing into the pump is pressurized and rises along the discharge passage to be sprayed through the nozzle. When the pressurization of the nozzle is released, the discharge passage is mechanically closed by the elevation of the nozzle, and as the pressure inside the pump decreases, contents are introduced from the container to compensate for this.

Such a pump is used for spraying various contents such as fragrances and cosmetics as well as fragrances and insecticides. In particular, the amount of content can be discharged by one-time nozzle pressurization, and since the content is not exposed to the outside, it is convenient to use, and the demand is increasing. A general structure of a conventional pump and a container in which the pump is coupled is disclosed in Korean Patent Registration No. 1963619 and the like.

On the other hand, the pump is connected to a long hose to discharge the contents from the body (main body) in which the contents are stored, and the lower end of the hose is in contact with the bottom surface of the body. The suction power of the pump is transmitted to the hose, and the contents stored in the body flow into the pump through the hose. Such a hose makes it possible to use all contents stored in the body, but is a factor that deteriorates the aesthetics of the body because it is inserted into the body and visible from the outside. In particular, when the body corresponds to a cosmetic container, the problem of deterioration in aesthetics is more prominent. Therefore, in many cases, the container using the pump is made of a non-transparent material to prevent the hose from being exposed to the outside.

Therefore, the present invention has been derived to solve the above problems, and is intended to provide a container for liquid injection capable of removing a hose by improving a passage structure through which contents are discharged.

14 to 15, the nozzle 230 has a nozzle protrusion 232 coupled to the valve 244 of the pump 240, and the nozzle protrusion 232 communicates with the outlet 234. And the valve 244 has a nozzle circumferential surface 236, which is partially inserted into the pump coupling part 220 of the shoulder 210. The valve 244 is elastically supported by a spring (not shown), so when the external force applied to the nozzle 230 is removed, it rises by the elastic restoring force of the spring. And the nozzle 230 is covered by the top cap 260.

The lower part of the pump 240 is inserted into the pump insertion space 164 formed in the body cover 160, and the housing 246 is pressed downward by the protrusion 224 of the shoulder 210 to be fixed in position. The pump 240 allows contents to flow into the pump insertion space 164 and sucks the contents into the pump insertion space 164 so that they can be discharged through the nozzle 230 .

The pump 240 includes a housing 246, a valve 244, a housing cover 250, a piston 248 and a guide 242, which are the same as or similar to the pump structure described in Korean Patent Registration No. 1963619. Therefore, a detailed description will be omitted.

Referring to FIG. 3, the contents in the filling space 112 by the suction force of the pump 240 are introduced into the body outflow passage 113 through the lower tube hole 150 formed at the bottom of the tube 140, and then It rises and is discharged to the outside of the body outflow passage 113 through the upper moving hole 130. Then, the contents are discharged through the upper moving hole 130 and introduced into the passage protrusion 172, and then introduced into the pump insertion space 164 through the cover inlet hole 170 and the cover channel 168. In addition, the contents are introduced into the housing 246 by the suction force of the pump 240 in the pump insertion space 164 and then discharged to the outside of the container 100 through the nozzle 230 .

As described above, since the container 100 according to the present embodiment does not include a hose for inhaling the contents inside the body 110, the structure is simple and it is possible to solve the problem of deterioration in aesthetics due to the hose.

As the contents are discharged from the inside of the filling space 112 by the pump 240, the pressure inside the filling space 112 may decrease. Since such a decrease in pressure inside the filling space 112 causes a decrease in suction power of the pump 240, it is necessary to maintain the pressure inside the filling space 112 at a constant pressure (eg, atmospheric pressure).

In the container 100 according to the present embodiment, outside air is introduced into the pump coupling portion 220 through a gap (no reference numeral) formed between the nozzle 230 and the inner circumferential surface of the pump coupling portion 220 . The air introduced into the pump coupling part 220 is introduced into the filling space 112 through the shoulder air hole 226, the support air groove 202, and the air nozzle 146. In this way, the suction power of the pump 230 may be maintained at a constant level by introducing air from the outside into the filling space 112 to maintain atmospheric pressure.
