Discharge of viscous liquid contents by pumping

Like the known viscous liquid dispensing container by pumping, the embodiment of the present invention basically comprises a container body 100 for containing a viscous liquid; A push button 200 having a discharge tube 210 formed therein by a pressure of a hand to discharge a viscous liquid; A container stopper 110 through which the push button passes and prevents the viscous liquid of the container main body 100 from being poured out; And a container auxiliary stopper 120 for fixing the push button 200 to a pumping means inside the container body 100 to be described later and an upper part of the container stopper 110 so as to be integrated with the container stopper 110.

However, the container auxiliary stopper 120 may have a separate structure according to the manufacturing method or may be integrally formed on the upper part of the container stopper 110. [ Also, the push button 200 and the container stopper 110 may be integrally formed.

The interior of the container body (100) of the viscous liquid discharge container by pumping includes: A double pump 300 which is fixed to the container stopper 110 and is coupled to the lower portion of the push button 200 so as to move up and down in the interior thereof and in which a space for storing a predetermined amount of viscous liquid contents is formed; The upper part is connected to the lower part of the double pump 300 so as to communicate with the internal space of the double pump 300 and the lower part is connected to the lower part of the container body 100, A discharge hose 400 of the type shown in FIG.

The double pump 300 is coupled to a lower portion of the push button 200 or extends downward to move up and down in contact with a certain inner surface of the double pump 300, A suction piston 312 having a piston discharge pipe (not shown) communicated with the discharge pipe 210 inside the pump 200; When the push button 210 is pushed and moved downward by the double pump 300, the suction piston 312 is moved upward by an elastic force to restore the suction piston 312 to its original position, (313); The piston 312 is blocked by the pressure when the piston 312 moves downward and the piston 312 is coupled to the discharge hose 400 by the elastic means 313 Closing means 314 functioning to open a point where the double pump 300 and the discharge hose 400 are coupled to each other when moving upward. When the suction piston 312 is coupled with a separate component from the push button 200, the push button 200 is formed with a piston support part 220.

A point where the double pump 300 and the discharge hose 400 are coupled to each other is referred to as a pumping suction port 311a. The elastic means 313 may preferably be a spring, and the opening and closing means 314 may preferably be a stopping mechanism.

The operation of discharging the viscous liquid content by pumping will be described. The following description of the dispensing of viscous liquid contents by pumping is schematic. When the user depresses the push button 200 by hand, the suction piston 312, which is coupled to the lower portion of the push button or has a long lower portion thereof, is lowered, and the suction piston 310 is inserted into the contents suction portion 310 of the double pump 300 Pressure is applied. By this pressure, the opening and closing means 314 closes the pumping suction port 311a, and the inside of the pump 311 becomes a milf space; The viscous contents stored in the double pump 300 are discharged from the container through the piston discharge pipe and the discharge pipe 210. When the opening / closing means 314 is not provided or the pumping suction port 311a is blocked The contents are moved to the contents suction unit 310 by the air pressure that the air is introduced into the container body 100 from the pressing unit 320. [

On the other hand, when the user removes the pressure by releasing the pressure from the push button 200, the suction piston 312 is moved upward by the elastic means 313, and the discharge pipe 210 is closed The internal pressure of the double pump 300 increases as the volume increases and the opening and closing means 314 opens the pumping suction port 311a so that the viscosity of the viscous material 311 stored in the inner space of the container body 100 The liquid is moved into the double pump 300 along the discharge hose 400 and stored in a predetermined amount. As described above, the predetermined amount of the viscous contents moved into the double pump 300 is discharged again as described above during the next pressing operation.

Double structure exhaust pump by partition wall,

The most significant feature of the present invention is that the double pump 300 has a double structure of a partition wall. More specifically, the double pump 300 includes a suction suction portion 310 and an air suction portion 320. The content suction unit 310 has the same function as the contents suction unit 310 of the double pump 300 described previously and the compressed air unit 320 applies pressure to the inside of the container body 100 to perform a pumping operation To be smooth. With this configuration, the operating step of the push button 200 can be smooth, unlike the conventional pumping vessel. 6 (a) is a cross-sectional view (AA cross-sectional view of FIG. 2) of the double pump 300 of the present embodiment, but the double pump 300 may be formed of various types of cross-sectional views as shown in FIG.

To this end, in addition to the above-described suction piston 312, the piston operated by the push button 200 also requires a pressure piston 230. Like the suction piston 312, the pressure piston 230 may extend downward from the push button 200 or may be coupled to the lower portion of the push button 200 in a separate structure. The pressure piston 230 of the present embodiment is formed by extending the outer circumferential portion of the push button 200.

Air pressure switch valve

The air pressurizing unit 320 is configured such that external air flows in a state in which the pushbutton 200 is moved upward, Lt; RTI ID = 0.0 > 100 < / RTI >

The air pressurizing unit 320 includes a first valve 3211 and a second valve 3212. The first valve 3211 opens the inside of the pressurizing unit 320 and the outside of the container, And the second valve 3212 is an opening and closing means for opening and closing the inside of the pressurizing portion 320 and the inside of the container body 100. When the first valve 3211 is in contact with the inside of the container body 100, a hole 102 corresponding to the first valve 3211 is formed in the container body 100. Air can be introduced into the air pressure portion 320 through the hole 102 and the first valve 3211.

When the pressure piston 230 moves downward, the first valve 3211 is closed to shut off the air between the inside of the pressure portion 320 and the outside of the container, and the second valve 3212 is opened, The pressure of the pressing portion 320 is introduced into the container body 100. As a result, the pressure inside the container body 100 increases.

The second valve 3212 is closed when the pressure piston 230 moves upward and does not affect the pressure inside the container body 100 and the first valve 3211 is opened so that the pressure of the pressure piston 230 ) To move up.

4, a blocking mechanism 3214 is disposed in the through hole 3213, which penetrates the inner and outer portions of the air pressure portion 320, as shown in the example of the first valve and the second valve, 3213 are formed of a cut-off portion 3215 having a structure in which the inner diameter is gradually narrowed at one side so that when the blocking mechanism 3214 is in close contact with the cut-off portion 3215, . On the other hand, on the other side of the through-hole 3213, even if the stopping protrusion 3216 formed to prevent the stopping mechanism 3214 from coming off and the stopping mechanism 3216 are in contact with the stopping protrusion 3216, The inside and outside of the pressurizing portion 320 can communicate with each other even when the stopping mechanism 3214 is in contact with the stopping protrusion 3216. [

Meanwhile, a valve applicable to another embodiment is separately shown in the lower right of FIG. 4, which is formed by attaching one side of a rubber plate bent by elasticity to the periphery of a through hole. Various types of valves may be applied as described above.

In the case of the first valve 3211, the blocking portion 3215 faces the outside of the air pressurizing portion, and in the case of the second valve 3212, the blocking portion 3215 faces the inside of the air pressing portion .

The means for removing the sidewall residue in the container

In the case of the known viscous liquid contents container, the contents of the liquid are contained in the container body and it is difficult to utilize or remove the liquid contents. The contents on the inner wall are referred to as " container wall side wall residue " hereinafter.

The present invention includes means for sucking and using the contents in the container while at the same time not pushing the sidewall residue inside the container down to remain. This is referred to as a residue removing means, which means that the inside of the container body 100 is in contact with the inner wall of the container body, and as the contents are used, the inner wall wall residue is pressed downwardly, It is a function of summing. The residue removing means may be a flat plate-like top plate 500. This is a plate-like component that passes through the discharge hose 400 and covers the upper surface of the contents in the container body 100.

As shown in FIGS. 7 and 8, pressure is applied to the inside of the container body 100 by the dual pump having the double structure described above to move the flat top plate 500 downward. In this process, Water can be removed from the inner wall. In the step of pressing the pushbutton 200 to pressurize the inside of the container body 100 or the volume of the contents in the container body 100 is reduced while the pushbutton 200 is returned to its original position, .

5, guide protrusions (not shown) are formed on the outer circumference of the flat top plate 500 so as to be slidable corresponding to guide grooves 103 formed along the inner surface 101 of the container body 100 510 may be formed.

11 and 12 illustrate another embodiment of the present invention. Unlike the previous embodiment, the inner partition wall 330 having the lower portion communicating with the lower portion of the air is formed to separate the space, And the first valve 3211 is formed in a wall of the other space. Such a configuration allows the position of the first valve 3211 to be easily designed and changed, and the desired purpose can be achieved without forming the hole 102 of the previous embodiment separately.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims and their equivalents.
