Description

Vacuum cosmetic instrument having structure for quantitative discharge with downward nozzle head}

The present invention is a device for dispensing a certain amount of contents at all times in a nozzle head-down vacuum type cosmetic container accommodating high functional cosmetics.

In general, high-performance cosmetics such as essences, high-end lotions, and creams used for the purpose of anti-wrinkle / relieving, whitening, and sun protection are mostly vitamins or natural natural extracts. When exposed to air (oxygen) or sunlight (ultraviolet), there is a problem that rancid easily.

Conventionally, in order to solve such a problem, a fixed-quantity ejection structure is known in an airless cosmetic container having various structures, but this is a structural content of a "nozzle head restoring type" in which the head is restored again after the ejection of the contents when the nozzle head is pressed. After filling and packaging, there is a problem that the structure of the container is complicated as well as a fatal defect that the contents of the container are always in contact with air (especially oxygen) and are easily dissipated by interaction due to the presence of an air layer in the upper layer of the container.

Prior art Korean Patent Publication No. 1999-0066973 "Discharge apparatus for liquid or paste material and its assembly method" is known, but the contents are discharged at the same time by the pressing pressure of the nozzle head, the contents There is a problem that can not be quantified.

My patent application No. 2001-35668, "the contents discharge structure of the airless pump type cosmetic container" is known in the prior art,

The prior art forms a tooth at regular intervals on the circumferential wall of the support erected in the center of the container and presses the nozzle button with the guide protrusion formed on the inner surface of the piston support member fitted thereto, the guide protrusion rotates over the teeth one by one. It is possible to discharge the contents at the pressure of lowering the piston, but it is possible to discharge the contents quantitatively, but if the pushing force of the nozzle button is strong, the guide wheel will be over several teeth and a large amount of contents may be discharged. .

The present invention effectively solves the problems of the prior arts, and even after the contents are discharged, there is no idle air layer in the upper layer of the container, and the container is always filled with only the volume of the indoor object, so that the contents are safely used without preserving the rancidity. Unlike conventional airless cosmetic containers for nozzle head restoration, the contents pumping member is lowered by a predetermined distance each time the nozzle head is pressed, and the contents are discharged as much as the lowered distance and the contents inlet is closed by a valve. The technical problem of the present invention is that the nozzle head is no longer lowered and the metered discharge is possible.

The nozzle housing 20 is assembled to the container housing 10, the sealing member 15 for sealing the bottom of the container housing 10 and the container housing 10, the nozzle hole 21, the liquid housing is accommodated ) And a piston having the cylindrical cylinder 41 is fixed to the piston member 30 and the piston member 30 built in the container housing 10 so that the elastic rib 31 is in close contact with the inner wall of the container housing 10. The member holder 40 and the nozzle head 20 are fitted to the upper end, and the lower part is inserted into the cylindrical cylinder 41 of the piston member holder 40 and has a center shaft 50 and a nozzle head having a liquid passage 51. In the well-known vacuum-type cosmetic container consisting of a spring 60 to exert a resilient force to the 20, formed in the central portion of the piston member 30, the cylindrical support portion that the central shaft 50 is fitted ( 300),

It is formed on the bottom surface of the piston member holder 40 so that the liquid collection chamber 400 and lower portion of the piston member holder 40 communicate with the liquid collection chamber 400 and the cosmetic liquid receiving chamber of the container housing 10. A liquid inlet hole 401 and a lower circumferential wall on the lower circumferential wall of the central shaft 50 have a recessed stepped portion 501 and a lower portion provided with a recessed stepped portion 502. The liquid suction hole 504 and the inner wall 602 of the opening and closing portion 503 formed in the lower portion and opening and closing the liquid inlet hole 401 and the recess 500 and the inner wall 602 are 504 The center shaft 50 so that the hole 601 fitted into the groove 500 to be opened and closed is drilled in the flat portion 603 and the outer circumferential wall is in close contact with the inner wall of the cylindrical cylinder 41 of the piston member holder 40. It is made of an elastic pumping member 600 mounted on the).

3 and 4 show another configuration example of the present invention, in order to simplify the structure of the central shaft 50 having an opening and closing portion 503 at the bottom to enable quantitative discharge without a pumping member. The cylindrical opening and closing portion 310 in close contact with the body portion is integrally formed with the piston member 30 to open and close the liquid suction hole 504 drilled in the central shaft 50.

In the drawings, reference numeral 700 is an overcap.

It demonstrates the effect of the present invention made of the above configuration.

When the contents are received through the bottom of the container housing 10 and then the sealing member 15 is inserted into the container housing 10, pressure is generated in the container housing 10, and the elastic pumping member 600 is opened by the pressure. Contents may be introduced into and discharged to 504, but the cylindrical support 300 may hold the flat portion 603 of the elastic pumping member 600 so that the pumping member does not open. You can stop it.

The liquid cosmetics contained in the container housing 10 are kept completely sealed without the air layer in the container by the piston member 30 or the sealing member 15.

1 shows a center shaft 50 fixed to the nozzle head 20 and the nozzle head 20 by the elastic force of the spring 60 interposed between the piston member 30 and the nozzle head 20. And the elastic pumping member 600 fitted into the groove 500 of the central shaft 50 is in a raised state. In such a state, the liquid collecting chamber 400 formed in the lower portion of the cylindrical cylinder 41 of the piston member holder 40 is raised. The liquid cosmetic in the container housing 10 flows through the liquid inlet hole 401.

When discharging the liquid cosmetic in such a state, when the nozzle head 20 is raised as shown in FIG. 2, the nozzle head 20 and the center shaft 50 are lowered and the elastic pumping member 600 is simultaneously. When lowered, the pressure of the elastic pumping member 600 which is continuously lowered while the opening / closing part 504 formed at the lower end of the center shaft 50 closes the liquid inlet hole 401 is applied to the liquid cosmetic in the collection chamber 400. When the pressure in the collection chamber 400 is increased and the center shaft 50 presses the elastic pumping member 600, the flat part 603 of the elastic pumping member 600 is crushed inwards, so that the groove 500 is formed. The liquid cosmetics of the collection chamber 400 are formed in the liquid suction hole as the lower portion of the inner wall 602 of the hole 601, which is in close contact with the inner wall of the hole 601, is opened (see FIGS. 2 and 6). 504 flows into the liquid passage 51 of the central shaft 501 and the nozzle head It will be discharged into the nozzle hole 21 of 20. The

The stepped jaw 501 formed on the upper portion of the groove 500 is inclined downward so that the inclined stepped jaw 501 presses the flat portion 603 of the elastic pumping member 600 as the center shaft 50 descends. The inner portion of the inner wall 602 is opened while the planar portion 603 is naturally distorted inward.

In addition, when the opening and closing portion 503 of the central shaft 50 blocks the liquid inlet hole 401, the liquid cosmetics are no longer introduced through the liquid inlet hole 401, so that the nozzle head 20 can no longer be lowered. Only the liquid cosmetics of a certain amount stored in the collection chamber 400 are discharged.

When the nozzle head 20, which has been forcibly pressed, is released in this way, the inner wall 602 of the elastic pumping member 600 blocks the liquid suction hole 504 by the elastic force of the spring 60, and at the same time, the opening and closing part 503 becomes liquid. By opening the inlet hole 401, the liquid cosmetics in the container housing 10 are introduced into the collection chamber 400 by the suction force generated when the elastic pumping member 600 is lifted, and the piston as much as the liquid cosmetics are introduced into the collection chamber. The member 30 and the nozzle head 20 are lowered.

3 and 4 of the present invention, the fixed-quantity discharging structure shown in another embodiment of the present invention has a cylindrical opening and closing portion 310 formed integrally with the piston member 30 to open and close the liquid suction hole 504 to press the nozzle head 20. When the center shaft 50 is lowered at the same time while the liquid suction hole 504 perforated in the center shaft is lowered from the lower end of the cylindrical opening and closing portion 310, the contents of the liquid suction hole 504 by the falling pressure of the central shaft When the central shaft is lowered and the opening / closing part 503 blocks the liquid inlet hole 401, the contents are no longer discharged, so that the quantitative discharge is easy.

The structure of the present invention having the above-described configuration and action effect is not only very simple but also there is no idle air layer in the container, which can prevent the spoilage of the contents, the operation is easy, the sealing state is good, and the shelf life of the contents can be increased, and by simple operation Once pumping will have the effect of discharging the contents of the quantitative.
