[0001] END PRESSURE TYPE PUMPING CONTAINER [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pumping container for discharging contents by pumping, and more particularly to an end-pressurized pumping container provided with a pump at an opposite end of a discharge port to discharge the contents by an end-pressing method.

Generally, a viscous content such as toothpaste or hand cream is sold in a soft tube, and a user releases the contents by pressing the tube by hand after detaching the lid. These applications are not limited to toothpaste and hand cream, but are also applied to kochujang and various edible sauces.

In the case of such a tube container, it is difficult to discharge by pressing by hand when the content of the container is small. That is, there is an inconvenience that the remaining amount of the tube should be used in a state in which the tube is partially cut off by pressing with excessive force.

In the case of contents such as shampoo, kitchen detergent, milk lotion, etc., which are relatively viscous, the contents are sold in a pumping container, and the user can easily use the contents by simply pressing the pumping part connected to the inlet of the container.

In the case of such a pumping container, the pumping portion for discharging the contents has a complicated structure including a valve, a spring, and the like, which not only requires a large manufacturing cost but also is difficult to apply to a tooth paste or a hand cream having a large viscosity.

An example of a proposed technique for solving such conventional problems is disclosed in Korean Patent Publication No. 1058404 (hereinafter referred to as "prior art") under the name "container having an air pump type operation port".

Although the container according to the prior art has improved use compared to the conventional containers as described above, the efficiency of pressurizing the air is somewhat lowered due to the characteristics of the corrugated pipe provided as the pumping means, and the air Since the inlet and the one-way check valve are provided in the corrugated pipe, the check valve can be broken or broken by the force of pressing by hand during use, and it is not easy to separate the tubular body from the protective cover for protecting the contents. have.

Korean Registered Patent No. 1058404 (Notice of 24th August, 2011) Korea Public Utility Model Publication No. 2011-0010649 (Published on November 15, 2011)

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art, and it is an object of the present invention to improve the pressurizing efficiency of pumping means for pressurizing air, to control the inflow of outside air well, In which the cartridge is easily detachable from an opening that protects the cartridge.

The end-pressure type pumping container of the present invention comprises a tubular cartridge body which is opened at both ends and filled with a viscous substance therein, a cartridge lid which is shielded at one end of the cartridge body and separated at the time of use, ; An operation port body that is detachably coupled to one end of the operation port body and connected to an opened end of the cartridge port body to discharge the viscous material to the outside, A pump for pumping air so that the piston slides in the direction of one end of the cartridge body; and a pump disposed between the cartridge body and the pump so as not to contact the pump to shut off or open the air inlet formed in the operation body in the pumping process of the pump. And an operation port having an air pressure regulating portion.

The pump is hemispherical with its own elasticity.

The end pressurized pumping vessel of the present invention further includes a pump stopper provided at the other end of the operating body to prevent overpressure of the pump and formed in the form of a hollow plate or mesh plate.

The cartridge stopper has a self-elastic force. When the pump is pushed, the pressurized air flows between the cartridge body and the operation body through the cartridge stopper. Keep airtight so that it does not leak.

The air pressure regulating portion includes a hollow sealing plate inserted in a groove formed in the inner periphery of the air inlet port of the inner surface of the operating body and having a self-elastic force; And a sealing lid which is made to open or close the air inlet in the operating body, has a self-elastic force, and is brought into close contact with the sealing plate when the air inlet is closed.

The end pressurized pumping container according to the present invention further includes a ring-shaped piston departure prevention portion provided inside each of both ends of the cartridge body to prevent the piston from coming off.

According to the present invention, the following effects can be expected.

First, since the air inlet for introducing the outside air and the air pressure regulating unit for regulating air inflow are provided at the positions spaced apart from the pump, there is no fear that the pump comes into direct contact with the air pressure regulator during operation of the pump, And the air inlet is also free from interference by the pump, so that the outside air can flow smoothly. This allows for better control of the pressurization of the inside air and the inflow of outside air during pumping.

Second, since the pump is formed of a material having a self-elastic force and formed into a hemispherical shape, the air is smoothly transferred to the piston when pressed, and the return to the original state is smoothly performed when the pressing force is released. Can be smoothly performed. In addition, since the pump stopper is provided in the operating port to prevent the pump from being excessively pressed, the pump can smoothly return to the original state during the pumping process, and the pumping can be performed well. On the other hand, since a single discharge amount is determined according to the size of the pump, it is possible to diversify one discharge amount by changing the size of the pump if necessary.

Thirdly, since the cartridge body is inserted at an interval from the inner surface of the operating body and the other end is seated while being in close contact with one surface of the cartridge stopper, the cartridge body can be smoothly separated from the operation port after use.

Fig. 4 is a right side view of the operating body shown in Fig. 3; Fig.

The end pressurized pumping container according to the present invention includes a cartridge 100 in which a viscous substance is filled and a cartridge case 100 in which the cartridge 100 is replaceably inserted, (200).

The cartridge 100 is a replaceable type that is replaced with a new one when the contents are all discharged, and is filled with a viscous material such as toothpaste, cosmetics in the form of a gel (e.g., hand cream, etc.), shampoo or the like. This cartridge 100 includes a cartridge body 110, a cartridge lid 120, a piston 130, and a piston departure prevention portion 140. [

The cartridge body 110 is formed in the shape of a circular tube opened at both ends and filled with a viscous material. The cartridge body 110 is attached to the inner surface of the operation lid 220, which will be described later, while the other end of the cartridge body 110 is closely attached to the cartridge stopper 240 to be described later. In a state in which the cartridge body 110 is fully inserted into the operation body 210, one end of the cartridge body 110 protrudes to the outside of the operation body body 210 so that the user can pull the protruded portion by hand The cartridge body 110 can be easily replaced.

The cartridge lid 120 is bonded to one end of the cartridge body 110 to prevent the viscous material from leaking through one end of the cartridge body 110. Before the cartridge body 110 is inserted into the operation hole 200 And is detached from the cartridge body 110. The cartridge lid 120 may be detachable as well as an adhesive type.

The piston 130 is slidably provided inside the cartridge body 110 to push the viscous material filled in the cartridge body 110 to the open end. The piston 130 is formed of an elastic material such as rubber or silicone, and the outer surface of the piston 130 is slid in contact with the inner surface of the cartridge body 110. The piston 130 also prevents the viscous material in the cartridge body 110 from leaking to the other end of the cartridge body 110. The outer diameter of the piston 130 is formed to extend from the center toward both ends, thereby improving airtightness and sliding smoothly.

The piston disengagement prevention portion 140 is formed in the shape of a hollow circular ring and is fixed to one end portion and the other end portion inside of the cartridge body 110 so that the piston 130 is released through both ends of the cartridge body 110 It prevents.

The operating member 200 includes an operating body 210, an operating lid 220, a pump 230, a cartridge stopper 240, a pump stopper 250, and an air pressure regulating portion 260.

The operation body 210 is formed in a circular tube shape and a cartridge space 211 into which the cartridge body 110 is inserted is formed. An engaging portion 212 having a screw thread is formed on an inner side of one end of the operating body 210 to allow the operating lid 220 to be detachably coupled.

One end of the cartridge body 110 protruding out of the operation body 210 through one opened end is inserted into the operation port cover 220, A discharge portion 221 having a discharge port 221a formed at the center of the other end thereof and a coupling portion 222 extending from one end of the discharge portion 221 and having the same diameter, 222 formed in the discharge port 221 and formed in a conical shape having a reduced diameter while being directed toward the discharge port 221a toward the discharge port 221a so that the opened end of the cartridge body 110 is closely contacted, And a cartridge contact surface 223 for guiding the material toward the discharge port 221a.

Although not shown in the drawing, a separate cap may be removably provided outside the discharge port 221a to maintain the airtightness of the discharge port 221a when not in use.

The pump 230 is formed in a semi-spherical shape using a material having elasticity such as rubber or silicone. The pump 230 is fixed to the other end of the operation body 210 by an adhesive method. When the piston 230 is pushed, (130) to slide the piston (130) in the direction of one end of the cartridge body (110), and when the pressing force is released, the piston (130) returns to its original state. Due to the shape of the hemispherical pump 230, the air in the pump 230 is smoothly transferred toward the piston 130 in a short time when the pump 230 is pressed, and when the force pressing the pump 230 is released The external air can smoothly flow into the pump 230 in a short time, and the pump 230 can be restored to its original state smoothly. That is, the pump 230 is formed in a hemispherical shape so that pumping can be performed smoothly. Meanwhile, since the discharge amount is determined once according to the size of the pump 230, the size of the pump 230 can be varied according to need.

The cartridge stopper 240 is fixed to the inside of the other end of the operating body 210 by an adhesive method at a distance from the pump 230. When the cartridge body 110 is inserted into the operating body 210, The other end of the body 110 is seated while being closely attached, and airtightness is maintained so as to prevent air from leaking between the cartridge body 110 and the operation tool body 210. The cartridge stopper 240 having such a function is formed into a hollow ring shape using an elastic material such as rubber or silicone.

The pump stopper 250 is a circular plate having a hollow circular plate or a rigid net and is provided between the cartridge stopper 240 and the pump 230 at the other end of the operating body 210 to prevent the pump 230 from being excessively pressed . That is, when the pump 230 is excessively depressed, the pump 230 may not return to the original state or may not be smoothly returned. Therefore, excessive depression of the pump 230 may be limited by using the pump stopper 250.

And may be integrally formed with the operation body 210 as shown in the drawing, or they may be separately molded and then bonded.

On the other hand, pressurized air is pumped to the inside of the other end of the cartridge body 110, the other end of the operation body 210, the center of the pump stopper 250 and the pump 230 An inner space connected to each other is formed so as to flow into the other end of the cartridge body 110 and push the piston 130 therebetween. Between the cartridge stopper 240 and the pump 230 at the other end of the operating body 210, a plurality of air inlets 213 through which external air flows into the internal space are formed at equal intervals.

The air pressure regulating unit 260 is provided inside the other end of the operating body 210 so as to be spaced apart from the pump 230 and controls inflow of external air through the air inlet 213. The air pressure regulating unit 260 includes a sealing plate 261, And a cover 262.

The sealing plate 261 is made of a material having elasticity such as rubber or silicone and is formed in the shape of a circular plate having a through hole 261a at the center thereof and is fixed to the inside of the other end of the operating body 210. The through hole 261a of the sealing plate 261 is connected to the air inlet 213 of the operation body 210 and the sealing plate 261 is operated so as not to protrude into the interior of the operation hole body 210 Inside the spherical body 210, a sealing plate insertion groove 214 is formed around the air inlet 213.

The sealing lid 262 is made of a material having elasticity, such as rubber or silicone, and is fixed in such a manner that only one edge is adhered to the sealing plate 261, thereby opening and closing the air inlet 213. That is, when the internal air is pressed by pressing the pump 230, the sealing lid 262 is pressed toward the sealing plate 261 by the pressurized air to close the air inlet 213 and press the pump 230 The sealing lid 262 is separated from the sealing plate 261 by the difference in the air pressure between the inside and the outside of the operating member 200 and the air inlet 213 is opened to allow the outside air to flow. The sealing lid 262 is formed in a shape in which the cross-sectional area of the sealing lid 262 is reduced from one surface contacting the sealing plate 261 to the opposite surface, so that the closing operation and the opening operation can be smoothly performed when the pump 230 is operated. Further, since both the sealing lid 262 and the sealing plate 261 are made of a material having an elastic force, airtightness is improved when they are brought into contact with each other.

Since the air inlet 213 and the air pressure adjusting unit 260 are provided at the positions spaced apart from the pump 230, the pump 230 may be in direct contact with the air pressure adjusting unit 260 during operation of the pump 230 It is possible to prevent breakage of the air pressure regulating part 260 due to the pump 230 and to smoothly introduce the external air without interference of the air inlet 213 and the pump 230. Accordingly, it is possible to control the pressurization of the inside air and the inflow of the outside air while pumping, and as a result, the discharging efficiency of the contents can be improved.

Hereinafter, the operation of the end-pressure type pumping vessel according to the preferred embodiment of the present invention will be described with reference to FIGS. 5 and 6. FIG. FIG. 5 is a sectional view showing the state where the pump is depressed to discharge the viscous material of the cartridge, and FIG. 6 is a sectional view showing the state when the force pressing the pump is released.

5, when the pump 230 is pressed in the dispensing direction of the viscous substance, the air that has been filled in the space between the pump 230 and the piston 130 is pressed toward the piston 130, I.e., toward one end of the cartridge body 110, to slide the viscous material. The piston 130 slides so that the viscous material in the cartridge body 110 is discharged to the outside through the open end of the cartridge body 110 and the discharge port 221a of the operating lid 220. [

The pressurized air between the pump 230 and the piston 130 leaks to the outside because the sealing lid 262 is pushed toward the sealing plate 261 by the air pressure and the air inlet 213 is closed, I do not go out. Also, since the pressurized air does not leak through the cartridge stopper 240 between the cartridge body 110 and the operating body 210, the smooth sliding of the piston 130 can be achieved.

The pump 230 is pushed until it contacts the pump stopper 250. Of course, when the pressing force applied to the pump 230 is low, the pump 230 may not contact the pump stopper 250. However, even if the pressing force applied to the pump 230 is large, Excessive pressure is prevented. Accordingly, when the pressing force applied to the pump 230 is released, the pump 230 can be smoothly returned to the original state irrespective of the magnitude of the pressing force applied to the pump 230.

On the other hand, since the open end of the cartridge body 110 is in close contact with the cartridge contact surface 223 formed on the inside of the operation port cover 220, the viscous material does not leak out of the normal discharge path.

6, when the pressing force applied to the pump 230 is released, the pump 230 returns to its original state due to its elastic force. In this process, a pressure difference is generated between the inside air of the internal space formed between the pump 230 and the piston 130 and the outside air outside the operating port 200, and the air inlet 213 is opened The air outside the actuating opening 200 is filled into the internal space through the air inlet 213 as the closing lid 262 which has been closed is separated from the closing plate 261. [ In this process, the pump 230 returns to its original state more smoothly due to the inflow of outside air. When the pressures of the inside air and the outside air become equal to each other, the inflow of the outside air is stopped, and the sealing lid 262 comes into contact with the sealing plate 261 again by its own weight.

By repeating the pumping operation by pressing and releasing the pump 230 by hand as described above, the user can discharge as much content as desired. When the use is completed, the cap is fitted to the outside of the discharge port 221a of the operation port cover 220 to seal the discharge port 221a, thereby preventing the contents from leaking out or from the outside.

When all the contents of the cartridge body 110 are used, the user opens the operation port lid 220, takes out the cartridge body 110, and replaces it with a new cartridge. The cartridge body 110 is inserted at an interval from the inner surface of the operation body 210 and the other end is in a state of being in close contact with one surface of the cartridge stopper 240,

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, and that various changes and modifications may be made without departing from the scope of the appended claims. can do.
