Description

Pump-type liquid container with automatic pop-up outlet {PMUP TYPE LIQUID CONTAINER}

The present invention relates to a pump-type liquid container that can contain and store liquid substances such as cosmetics, shampoo, and detergent, and more particularly, has a structure in which the outlet protrudes when used by a pumping operation and the outlet is accommodated when not in use. It relates to a pump type liquid container.

In general, a pump-type liquid container is used as one of the means for discharging and using an appropriate amount of the contents contained in the container.

A pump-type liquid container is a container designed to be used by discharging the contents contained in the container in small amounts by a pumping operation, and is mainly applied to liquid containers storing liquid contents such as cosmetics, shampoo, and detergent.

The pumping operation of the pump-type liquid container is that pressure is generated by the force of the user pressing the button so that a certain amount of the contents can be discharged to the outside. A vacuum pressure is generated, and the contents contained in the storage container are sucked by this vacuum pressure and discharged to the outside through the nozzle in a certain amount through the flow path.

Such a conventional pump-type liquid container has the advantage that the user can easily discharge the contents using the push button, but since the discharge port is always exposed, the contents may leak, and in particular, the button is not pressed. Since the contents remaining inside the high tube are filled with the flow path, there is a risk of flowing down, making it difficult to store and carry.

Therefore, if you want to store or carry a pump-type liquid container, a separate stopper is provided to prevent the contents from leaking, and the contents are blocked so that the contents do not get on the small items carried together.

However, as containers used in the cosmetic field such as cosmetics require design and fashionableness and pursue individualization and luxurious aesthetics, the exterior design is very important. There is a problem in that it cannot provide a beautiful aesthetic feeling.

In addition, if the cover is provided separately, it is inconvenient to use it after removing the cover first and then putting the cover back on after use. There are many, but in this case, there is a problem that the cover is often lost in the process of opening the cover and using it, because there are many types of mixed ones.

In addition, since the discharge port is exposed, the contents may be hardened near the discharge port. In particular, the higher the viscosity, the faster the blockage of the flow path during curing, and the internal pressure is applied to the flow path during pumping operation while not in use for a long time. There is a risk that the connection part forming the flow path may be damaged or burst.

The present invention is to solve the above problems, and has a structure in which the outlet of the pump type liquid container is automatically popped up by the pumping operation so that the outlet is exposed when the container is used and received when the container is not used. It implements an integrated design without the need for a cover, and has a structure that can prevent leakage when discharging the contents as well as when storing and carrying.

In addition, when the contents are hardened and the flow passage is clogged, it is possible to prevent the flow passage connection structure from being easily damaged or damaged even if an internal pressure is generated during the pumping operation.

The present invention as a technical idea for achieving the above object is a pump-type liquid container in which a pumping cap is mounted on the upper end of a storage container that can contain liquid contents and discharges the contents contained in the storage container by pressing the pumping cap. In this case, when the pumping cap has a built-in pump in a state in which the protruding and protruding member is mounted in the housing to pop-up, the protruding member pops up when the pumping operation is performed by pressing the press cap so that the discharging port is opened to discharge the contents, , such a linked operation of the protruding and protruding member and the pressing cap is such that when the presser is lowered in a state in which the protruding and retracting member is pivotally coupled to the shaft, the pusher presses the guide of the protruding and protruding member to pressurize the pop-up operation and at the same time the pumping operation is made. will be.

In addition, the protruding member is accommodated in the receiving part formed in the housing, and the protruding member is popped up only when the pumping operation is performed by restoring the protruding member by the elastic member and folding it so that the contents are discharged through the outlet, and the container When not in use, the protruding member can be folded and stored.

In addition, a soft tube is assembled at the upper end of the pump, the flow path is connected to the outlet side to discharge the contents, and the tube is fixed at the upper end of the pump by the step formed in the tube connecting part and the tube connecting part, and then a binding material is applied to the outer periphery of the pump. By preventing the fitting tube from being separated, even if internal pressure is applied to the flow path by the pumping operation, damage to parts or flow path rupture is prevented and the contents can be discharged.

In addition, in an embodiment of the present invention, the pump for sucking and discharging the contents of the liquid phase, a piston for sucking the contents of the liquid phase and discharging the contents of the liquid phase, one end is coupled to the piston and the contents of the liquid phase The suction, the other end from which the inhaled liquid content is discharged is a tube connection part coupled to a tube, a tube coupled to the tube connection part and having a hollow formed so that the liquid content is movable, and a combination of the tube connection part and the tube and a binder for coupling the tube connecting portion and the tube by applying pressure to the portion.

According to the pump-type liquid container of the present invention, in contrast to the conventional discharge port made of an exposed type and the discharge port is disposed at the top of the container, residues or leakage are generated, the discharge port is discharged from the container by the pumping operation of the present invention. Due to the structure that automatically pops up and the discharge port protrudes from the storage container, even when the contents are discharged, they fall apart from the container, so there is no risk of the contents sticking to the body. In this case, since the discharge port can be stored in a non-exposed manner by folding, the storage volume can be reduced, and storage and portability are very easy.

In addition, since it is possible to implement an integrated design of the pumping cap without the need for a cover, it is possible to secure design and provide a new aesthetic design.

In addition, since the discharge port is not exposed to the outside when the container is stored and carried, it is possible to prevent damage to adjacent stored items due to leakage, as well as to prevent leakage by controlling the discharge due to the folded structure of the nozzle. It prevents arbitrarily pumping and enables clean and safe use.

In addition, even if some hardening occurs in the flow path near the discharge port due to not being used for a long time, even if the internal pressure rises due to the pumping operation, it is possible to prevent the inner tube from being separated or damaged, greatly improve durability, and pressure loss during pumping operation. The contents can be discharged smoothly by minimizing the

In order to correspond to each other, the second assembly part 150 is formed to be coupled in a hook manner, so that assembly can be made in a forced fitting structure.

In addition, the pedestal 140 is provided with a tube body 142 for mounting the pump 300 in a fixed position, and the inner diameter of the tube body 142 has a seating part ( 143) may be formed.

That is, the pump 300 built in the housing 100 connects the flow path from the storage container 1 to the discharge port 220 side so that the contents are discharged. It is connected to discharge the contents, and as a structure for transporting the contents through the tube 320, the piston 360 is mounted on the cylinder 340 to make a reciprocating motion, and the piston 360 is a spring 380 ) is repeatedly operated by the restoring force, and the check valve structure is formed to guide the contents along the flow path only in one direction, that is, in the discharge direction, so that the contents are repeatedly sucked and discharged.

At this time, the pump 300 is first assembled to the upper side of the pedestal 140 by allowing the cylinder 340 of the pump 300 to be mounted in a fixed position on the seating portion 143 formed on the pedestal 140, and then the pump holder By assembling 160 , it is possible to assemble the pump 300 to the pedestal 140 and the pump holder 160 in the correct position by sequential assembly.

In addition, the tube 320 formed at the upper end of the pump 300 is inserted into the pump holder 160, at this time, the tube 320 is drawn out by forming an opening 162 so that the tube 320 can be withdrawn. It may be connected to the outlet 220 of the member 200 .

And the body part 120 of the housing 100 is provided with a receiving part 122 having a structure inside so that the protruding member 200 is assembled and folded and accommodated, and the pump holder 160 has a pump 300 . By the operation of the protruding member 200 by forming an opening 162 at a position corresponding to the receiving part 122 so that the tube 320 that is mounted on the upper end and constitutes the discharge flow path is drawn out and guided to the protruding member 200 . As the flow path of the tube is opened or blocked, the flow path opening/closing setting can be made.

On the other hand, when the protruding member 200 is popped up, the flow path of the tube is opened, and when the protruding member 200 is folded, the tube is folded or the flow path can be blocked by a blocking member (not shown). 200 is axially coupled to the housing 100 and rotates to perform a pop-up operation, and a discharge port 220 is formed at the tip of the protruding member 200 to discharge the contents.

The protruding and protruding member 200 is shaft-coupled to the housing 100 and rotates up and down to perform a folding operation, and is popped out or accommodated in the receiving unit 122 by this folding operation, and the protruding member 200 ), the protrusion 240 is formed on both sides of the rear end, and the protrusion 240 is assembled in the shaft groove 124 formed in the receiving part 122 of the housing 100 to be pop-up or folded.

At this time, the protruding member 200 is interlocked with the pressing cap 400 for operating the pump 300 to be operated, and when the pressing cap 400 is pressed, the protruding member 200 pops up It may be configured to discharge the contents.

To this end, as shown in FIGS. 9 and 10 , a pusher 420 is formed on the press cap 400 in the downward direction of the press cap, and the movement of the protruding member 200 is controlled while being pressed by the pusher 420 . When the guide 260 is formed to control, the operation can be made in connection with the pressing cap 400 in a state in which the protruding member 200 is shaft-coupled to the housing 100, and the guide 260 is a protrusion. When the tip of the 240 is bent and the protruding member 200 is accommodated, the guide 260 maintains a horizontal state so that when the pressing cap 400 descends, it is pressed by the pusher 420 and retracts. The member 200 may be rotated to pop-up.

At this time, the pressure cap 400 may be configured to be assembled with the body portion 120 of the housing 100 in a hook manner, and in this case, the pressure cap 400 is attached to the assembly portion of the pressure cap 400 in the housing 100 . It is assembled to form a flow section 410 so that it can rise and fall within a range set up and down in the assembled state.

In addition, the protruding member 200 is equipped with an elastic member 280 to provide a restoring force in a structure such as a torsion spring, so that a restoring force is generated in a direction in which the protruding and protruding member 200 is folded after discharging the contents. ) can be returned to its original state so that it can be stored in

At this time, the protruding member 200 may press the pressing cap 400 and each time the pumping operation is performed, the guide 260 is pressed so that the protruding member 200 pops up to the outside, but more preferably the protruding member ( It is desirable to continuously maintain the state after popping up the press cap 400 when the first pumping operation is performed in the state in which the 200) is accommodated. can do.

That is, a stopper 126 may be formed in the body portion 120 so that the guide 260 is caught and temporarily fixed on the path on which the guide 260 reciprocates, and the stopper 126 is the guide 260 . It is formed in a cylindrical structure on the reciprocating path, and by making the guide 260 also have a cylindrical structure corresponding thereto, as shown in FIG. Alternatively, the jammed state can be released.

Therefore, when the press cap 400 of the pumping cap 2 is pressed to discharge the contents, the protruding member 200 pops up and the outlet 220 is exposed so that the contents are discharged or ready for discharging, and in that state the protruding member 200 ) is to maintain the pop-up state, and after discharging the contents while repeatedly performing a pumping operation, the protruding member 200 is pressed by hand to temporarily fix the guide 260 and the stopper 126 . When released, the protruding and retracting member 200 is returned to its original position by the restoring force of the elastic member 280 and is accommodated in the receiving part 122 .

Therefore, since the protruding member 200 is not exposed in normal times, it is easy to store and carry, and the protruding member 200 is exposed only when used to discharge the contents, and an automatic pop-up is made by the operation of the pumping cap (2). Therefore, it is very convenient to use, and since the outlet 220 is located at the tip of the protruding member 200 in a popped-up state, there is no risk of the contents flowing down into the storage container 1, and it is clean and hygienic. The contents can be withdrawn.

At this time, the discharge port 220 is connected to the tip of the tube 320 of the pump 300 to discharge the contents. When the member 200 is folded, the outer surface of the tube 320 may block the flow path by the blocking member, thereby preventing leakage of fluid due to blocking the flow path.

And the discharge port 220 as a nozzle for discharging the contents may be equipped with an oil leakage prevention pad 222, the oil leakage prevention pad 222 is a film made of a soft material such as silicon is cut in the center of the inner pressure acts If the contents are discharged only to the container and internal pressure is not applied, the incised part is blocked by the restoring force of the soft body itself, thereby preventing oil leakage with a double structure.

And the pressure cap 400 for the pumping operation of the pump 300 is formed to protrude the lifting shaft 440 at the bottom, engage the pump holder 160 to induce vertical elevating and lowering while inducing the pump pressurization can be configured As there is, an auxiliary spring 460 for restoring the original position of the pressing cap 400 is provided on the lifting shaft 440 so that the pressing cap 400 can be lifted upward and ready to be pressed in a state in which the protruding member 200 is popped up. ) can be further installed.

Therefore, after performing a pumping operation by providing a restoring force to the pressing cap 400, the pressing cap 400 is restored to its original position to form a pumping ready state, and a repetitive pumping operation can be performed.

On the other hand, if the pump 300 does not operate for a long time, the flow path of the tube 320 and the like may be reduced or clogged as the contents are hardened. This may be damaged or breakage of the flow path may occur. By having a reinforcing structure at the flow path connection part, damage or breakage of the flow path can be prevented.

That is, in the structure in which the flow path is connected to the pump 300 , a tube connection part 302 for mounting the tube 320 is formed on the upper end of the pump 300 and the tube 320 is inserted and assembled, at this time in FIGS. 11 and 12 . As shown, a step 304 is formed on the tube connection part 302, and the tube 320 is made of a soft material and assembled by being fitted by force fitting so that the tip of the tube 320 is caught by the step 304 and fixed. At this time, the tube 320 is inserted into the tube connection part 302 and the outlet 220 of the protruding member 200 by assembling the penetrating binding material 330 to press the outer periphery of the tube 320 while being caught on the step 304. ) or when the contents remaining in the tube 320 of the pump 300 are cured, the pumping cap 2 is operated to improve the durability against the internal pressure even if the internal pressure of the flow path increases to prevent breakage or flow path rupture. have.

In particular, since the pump 300 is integrally formed inside the housing 100 of the pumping cap 2, the user cannot disassemble it, so even if the tube simply comes off, the product can no longer be used, that is, the tube. If 320 is pulled out, the pumping operation is performed, but the flow path is in a broken state, so it is in a malfunctioning state and has no choice but to discard the product because repair or maintenance is impossible. This prevents damage or damage to parts even if the internal pressure is large during pumping operation while reducing the flow path or clogging the flow path due to the hardening of the contents. .

At this time, the binding material 330 forms a chin on the cross-sectional structure to form a stepped tube, so that the inner periphery of the binding material 330 presses the outer surface of the tube 320 while pressing the tube 320 on the chin. While the remaining portion of the non-pressed portion is accommodated, the binding material 330 is more firmly fitted to the tube connection part 302 of the pump 300 to prevent arbitrarily separated, and durability can be further improved.

In addition, as shown in FIG. 13 , the binder 330 is manufactured in a shape in which one side of the ring is cut, and when the binder 300 is made of a material having elastic restoring force by its own elastic force, the tube connection part 302 . In a state in which the tube 320 is inserted, it can be assembled by fitting in the lateral direction, and at this time, an inclined surface is formed at the cut end of the binding material 330 so that it can be assembled by fitting in a one-touch method when assembling the fitting.

On the other hand, the lifting shaft 440 has a “C” cross-sectional structure so that the tube 320 can be accommodated during the pumping operation, so that it can be drawn out through the opening 162 while lifting and lowering as shown in FIG. 14 . The lower end of the shaft 440 directly presses the binder 330 to prevent the tube 320 from being separated, while the binder 330 does not flow and may maintain a rigidly assembled state.

At this time, the inner diameter of the lifting shaft 440 can accommodate the outer diameter in a state in which the tube 320 is inserted into the tube connection part 302, and by minimizing the spaced gap, the vertical elevation of the lifting shaft 440 is stable. In addition, the upper surface of the pump holder 160 has a structure in which the auxiliary spring 460 mounted on the lifting shaft 440 is blocked to be seated while the blocked upper surface is on the cross-sectional shape of the lifting shaft 440 . Correspondingly, as the perforated portion 164 is formed in a “C” shape, the lifting shaft penetrates the upper surface of the pump holder 160 and vertically reciprocating operation is made, and is vertically stable without being eccentric to either side. It can induce lift operation.

At this time, a screen 164 may be formed on the upper end of the pump holder 160 to prevent the auxiliary spring 460 from being exposed to the outside while the protruding member 200 is popped up to enhance the aesthetics. The shielding film 164 may be formed in a structure in which the press cap 400 is lowered and is interlocked so as to be raised and lowered in a state in which the center alignment with the pump holder 160 is made.

On the other hand, the pump-type liquid container of the present invention can also be used as a container for storing liquids by subdivision. In the case of storing several types of cosmetics, it can be stored more conveniently in various situations, as well as multiple pump-type liquid containers can be implemented as one integrated design, providing a design aesthetic.
