Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a push head unit of a pump dispenser,

The present invention relates to a push head unit of a pump dispenser, And more particularly, to a "push head unit of a pump dispenser" which can uniformly apply or massage (massage) the contents ejected through a push head unit according to a pumping operation of a pump dispenser, without using hands.

Generally, a pump dispenser is installed in a liquid or paste cosmetic or other container containing contents, and discharges a certain amount of contents through a push head, and is applied to various product groups such as cosmetics, detergent, shampoo, and food.

Such a conventional pump dispenser is a push head unit which is coupled to a container inlet and is equipped with a pumping unit having a pressure chamber formed therein for temporarily storing the contents therein and a nozzle for discharging the contents to the outside by applying pressure to the pressure chamber of the pumping unit. And the contents stored in the pressure chamber of the pumping unit are constantly discharged by the repetitive pressing operation of the push head unit. However, in the conventional pump dispenser, the contents contained in the container are simply pumped and discharged. Thus, when the contents are applied to the skin to perform the cleansing or massaging, there is an inconvenience in use that must be pumped to the palm.

In order to solve these drawbacks, the present applicant has filed a "Pump Dispenser with a Push-Head" application on September 26, 2011, in which the contents of the spray can be directly applied to the skin without using a hand, 10-1127411). 1; The " push head of the pump dispenser " disclosed in the applicant's invention No. 10-1127411 includes: A brush-mounting member 20 in the form of a disk and provided with a coupling hole 21 communicating with the leading end of the ejection flow passage 11 of the head-body 10 on the rear side and a contents spouting space 22 formed on the front side, Wow; A cover plate 30 disposed so as to cover a front surface portion of the brush-mounting member 20 and having a plurality of ejection holes 31 formed along the edge thereof; A plate portion 42 which is coupled to cover the front surface portion of the brush-mounting member 20 in which the cover plate 30 is disposed and in which the discharge ports 41 are perforated so as to communicate with the discharge holes 31, A hooking portion 43 which is provided at an edge of the plate portion 42 and which is elastically deformed to be detachably coupled to the rear surface of the brush-mounting member 20 by being wrapped around the rear edge thereof, A brush member 40 made of rubber and made up of massage-protrusions 44 that can come into contact with the hook-protrusions 44 and handle-protrusions 45 which are provided to protrude from the hooking portion 43 and can be caught when detached; . Therefore, when the push head is pressed, the content of the container is ejected toward the brush member 40, so that the contents can be directly applied to the skin through the massage-projection 45 without using the palm. Particularly, there is an advantage that a massage effect can be exerted while uniformly spraying the contents ejected through the massage-projections 45 of the brush member 40 to the skin.

However, in the push head disclosed in the above-mentioned invention No. 10-1127411, when the brush member 40, which is made entirely of a rubber material, is to be separated and cleaned, the handle-protrusion 45 is gripped and pulled, And after the cleaning, the hooking portion 43 is re-fitted while being elastically deformed.

The present invention has been made to solve such a problem, It is an object of the present invention to provide a massaging member on a push head of a pump dispenser in which contents are finally ejected so that the contents of the ejection can be evenly applied directly to the skin without using a palm, So that the pushing head unit of the pump dispenser can be easily detached.

<Description of Operation of Pump Dispenser Push Head Unit According to the Present Invention>

Next, operation and effect of the pump dispenser to which the push head unit according to the present invention is applied will be described with reference to FIGS. 7 and 8. FIG.

7, in the initial state of the pump dispenser 200, the hollow piston shaft 240 is lifted together with the push head unit 300 by the elastic supporting force of the coil spring 242, The contents are sucked and stored in the pressure chamber 221 of the cylinder 220.

In this state, the head-body 310 of the push head unit 300 is pushed downward; As shown in Fig. 8, the hollow piston shaft 240 descends (see the direction of arrow A in Fig. 8) while the spring force of the coil spring 242 is maintained. The contents filled in the pressure chamber 221 of the cylinder 220 are ejected to the outside through the nozzle hole 331 of the nozzle cover 330 and the ejection flow path 311 of the head- do. At this time, the check valve 230 disposed at the inlet port 222 of the cylinder 220 is brought into close contact with the valve seat portion 223 as the internal pressure of the pressure chamber 221 increases, ) To block the communication with the inside. The closing operation of the check valve 230 is performed from the moment when the piston shaft 240 descends. That is, the contents filled in the pressure chamber 221 at the moment when the piston shaft 240 is lowered together with the push head unit 300 apply pressure to the check valve 230 downwardly, and thereby the suction port 222 of the cylinder 220 ) Is firmly closed and there is no pressure loss during the pumping operation.

And releasing the push head unit 300; The pushing head unit 300 instantly rises together with the piston shaft 240 by the restoring force of the coil spring 242 so that the pressure chamber 221 of the cylinder 220 receives the vacuum pressure. The piston shaft 240 is lifted by the resilient restoring force of the coil spring 242 when the push head unit 300 is placed and vacuum pressure is applied to the pressure chamber 221 so that the check valve 230 is closed at the valve seat portion 223, The suction port 222 is opened so that a part of the contents in the container 100 is sucked into the pressure chamber 221 through the suction tube 224. [ The inside of the container 100 in which a part of the contents is removed is filled with the outside air of the volume through the air hole 225, so that the pump dispenser 200 is maintained in the initial state.

The contents are finally sprayed to the front surface of the nozzle cover 330 provided with the massage member 340 according to the pushing operation of the push head unit 300 so that the user can press the contents through the massage member 340 without using the palm It can be applied directly to the skin or cleaned (cleaned). At this time, the user can massage the skin through the massage member 340 and apply the contents evenly. Eventually, you can press the skin as you massage, apply the ingredients evenly, or clean (clean).

&Lt; Description of disassembling process of the nozzle cover of the push head unit according to the present invention &
