Field of the Invention The present invention relates to a container for containing contents such as liquid shampoo, detergent and soap having viscous properties, and a container for saving such contents, . More particularly, the present invention relates to a packaging container in which the contents of a packaging container are completely exhausted, waste of contents to be discharged is reduced, and pumping or suction is smoothly performed.

In general, viscous liquid shampoos, cosmetics, detergents and soaps are stored in a certain container and are commercially available. The container in which the viscous liquid contents are stored includes a form in which the user presses the body of the container to discharge the contents and a push button having an integrated discharge pump for the convenience of the user.

In recent years, pushbutton containers are mainly used due to convenience in use. When the user presses the push button on the upper end of the container, the pumping operation of the discharge pump at the lower end discharges only a liquid content of a proper amount through the push button at the upper end so that the container can be conveniently used by the user have.

However, the conventional containers have a problem that the operation of the discharge pump or the push button of the container is not smooth due to only the operation of pulling up by the negative pressure in the pumping function. Also, the suction process of the contents by pumping is achieved by repeating the step of applying pressure by the person and recovering by the elastic means, but the step of recovering by the elastic means is not smooth.

In addition, since there is a limit to pumped the viscous residual contents remaining on the inner wall or bottom of the container to the discharge pump, it is determined that it is no longer usable in spite of the fact that the residual contents remain, and the product is discarded as it is. It was the liquid contents of the viscous liquid, which remained on the inner wall of the container and could not be used or it was troublesome to use it. Such non-adverse remnants are wasted, and environmental pollution is caused by contamination of water quality when the residual contents are discharged. For this reason, in the process of being disposed of for recycling, residues remain in the container, requiring cleaning for recycling.

Configuration for discharging 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 discharge 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 lower part of the discharge pump 300 is connected to the upper end of the discharge pump 300 to communicate with the inner space of the discharge pump 300. The lower part of the discharge pump 300 is connected to the lower part of the container body 100, A discharge hose 400 of the type shown in FIG.

The discharge 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 discharge pump 300, A suction piston 312 having a piston discharge pipe (not shown) communicated with the discharge pipe 210 inside the discharge pipe 210; When the suction piston 312 is moved downward by the push button 210 and is moved downward by the discharge 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 is moved downward and the piston 312 is connected to the discharge hose 400 by the elastic means 313 Closing means 314 functioning to open a point where the discharge pump 300 and the discharge hose 400 are coupled to each other to communicate with each other. 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 discharge 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 / closing means 314 may be preferably an open / closed bowl.

The operation of discharging the viscous liquid content by pumping will be described. The discharge of the viscous liquid content by pumping is well known and the following description is outlined. 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, is lowered, and pressure is applied to the inside of the discharge pump 300; 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 discharge pump 300 are discharged through the piston discharge pipe and the discharge pipe 210 out of the container.

On the other hand, when the person 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 opening and closing means 314 opens the pumping suction port 311a while the inside of the discharge pump 300 is opened and the inside of the container body 100 is opened The stored viscous liquid moves into the discharge pump 300 along the discharge hose 400 and is stored in a predetermined amount. As described above, a certain amount of the viscous contents which have been moved into the discharge pump 300 and then discharged are discharged again as described above during the next pressing operation.

The operation of discharging the viscous liquid content by pumping is briefly described as a well-known technique as described above, and the construction and operation of the present embodiment to which the features of the present invention are applied will be described in detail below.

Features of the invention Constitution 1 (double structure exhaust pump, air pressurized pump by partition)

The most significant feature of the present invention is that the inside of the discharge pump 300 has a double structure of a partition wall. More specifically, the discharge pump 300 includes a suction pump 310 and an air pressure pump 320. The contents suction pump 310 has a function similar to that of the discharge pump 300 described above. The air pressurizing pump 320, which is a feature of the present invention, applies pressure to the interior of the container body 100, To be smooth. In this way, unlike the conventional pumping vessel, the pushing operation of the push button 200 can be performed smoothly after the operating step. 6 (a) is a cross-sectional view of the discharge pump 300 of this embodiment (AA cross-sectional view of FIG. 2), and the discharge 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.

(2) (Characteristics of the Present Invention) Structure 2 (Air Pressure Pump Opening / Closing Valve)

The air pressurizing pump 320 receives external air in a state in which the push button 200 is moved upward and the air introduced into the air pressurizing pump 320 flows into the container body 100). ≪ / RTI >

The air pressure pump 320 includes a first on-off valve 3211 and a second on-off valve 3212. The first on-off valve 3211 is connected to the inside of the air pressurizing pump 320, And the second on-off valve 3212 is an opening / closing means for opening and closing the inside of the air pressurizing pump 320 and the inside of the container main body 100. When the first on-off valve 3211 is in contact with the inside of the container body 100, the container body 100 has a hole 102 corresponding to the first on-off valve 3211. Air can be introduced into the air pressurizing pump 320 through the hole 102 and the first opening / closing valve 3211.

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

When the pressure piston 230 moves upward, the second on-off valve 3212 is closed so that the pressure inside the container body 100 is not affected. The first on-off valve 3211 is opened, (230) moves upward, so that no pressure is applied.

4, an open / close ball 3214 is positioned in a through hole 3213 passing through the inside and the outside of the air pressurizing pump 320 as shown in an example of the first open / close valve and the second open / close valve, The opening and closing ball 3214 is formed of a blocking portion 3215 having a structure in which the inner diameter gradually becomes narrower at one side so that when the opening and closing ball 3214 is in close contact with the blocking portion 3215, . On the other hand, on the other side of the through-hole 3213, a locking protrusion 3216 formed so as to prevent the opening / closing ball 3214 from slipping out and a locking protrusion 3216 protruding from the air- There is a through hole 3217 formed so as to be able to communicate with the inside and the outside. Even when the open / close ball 3214 contacts the latching jaw, the inside and outside of the air pressurizing pump 320 can communicate with each other.

On the other hand, an open / close valve which is separately applicable to another embodiment is 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 opening and closing valves may be applied as described above.

In the case of the first on-off valve 3211, the cut-off portion 3215 faces the outside of the air pressurizing pump. In the case of the second on-off valve 3212, As shown in FIG.

Characteristic constitution 3 of the present invention (container side wall residue removing means)

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 plate-type vertical moving plate 500. This is a plate-shaped component that passes through the discharge hose 400 and covers the entire upper surface of the contents in the container body 100.

As shown in FIGS. 7 and 8, by applying a pressure to the inside of the container body 100 by the discharge pump having the double structure as described above, the plate-type vertical moving plate 500 is moved downward, The sidewall residue 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 as the pushbutton 200 is put in place, .

5, on the outer circumference of the plate-type vertical moving plate 500, guide protrusions (not shown) formed slidably corresponding to guide grooves 103 formed along the inner wall 101 of the container body 100, (510) may be formed.

11 and 12 illustrate another embodiment of the present invention. Unlike the previous embodiment, a partition wall 330 through which the lower portion communicates is formed in the air pressurizing pump, so that the space is separated, And the first opening / closing valve 3211 is formed in the wall of the other space. Such a configuration allows the position of the first opening / closing 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.
