Description

PUSH PUMP MADE OF PP PLASTIC MATERIAL ONLY

The present invention simply improves the structure of the press pump for discharging various liquid contents, while all the parts constituting the press pump are made of only PP (polypropylene/polypropylene) plastic material, so there is no need to separate and discard the parts constituting the pump. It relates to a push pump made of only PP plastic material that can be collected and reused as it is, or recycled as a raw material for production of cosmetic-related subsidiary materials, while preventing environmental pollution caused by unauthorized disposal.

In general, as a means for discharging and using an appropriate amount of liquid contents such as cosmetics, shampoo, detergents, etc. contained in various containers including cosmetic containers, a kind of liquid push pump is used.

However, in spite of the convenience of using the conventional liquid push pump, various problems exist. The reason for this is that, first, the structure of the pump is complicated and there are many parts, so there is a problem that assembly and productivity are remarkably reduced. Next, the basic manufacturing material constituting the pump is plastic, but the ball that opens and closes the content inlet hole of the housing constituting the pump and the spring that elastically supports it in connection with the operation piston are made of steel.

Therefore, according to the conventionally provided liquid push pump structure, when the liquid contents are used up and the container is thrown away, users disassemble the pump to separate the spring including the steel ball and other plastic material. Parts are also disposed of separately, or some are separately collected and reused. However, if the steel material is discarded as it is, it will adversely affect the environment, and dismantle the pressure pump and use it as a steel material. In order to separate the balls or springs made separately, the labor cost and separation time required for this are required, and the efficiency of separate collection and recycling is also increased due to various reasons such as an increase in manpower and cost due to unnecessary separation work. It had to be lowered that much.

In consideration of the above problems, some pumps made by using a plastic material as a material of the press pump have been proposed in the prior art, but for some components constituting the press pump, for example, the steel used for elastic pressure operation of the button. Since the elastic means or elastic pump used instead of the spring of the material is made of an elastomer material having a rubber component, it provides good chemical resistance and elasticity, but in the case of an elastomer material, due to the nature of the material, Since it reacts, the elastic restoring force is somewhat lowered, and considering that it is manufactured with a resin such as PP (polypropylene) or PE (polyethylene) to supplement mechanical properties, it is used as an elastic means of the elastomer material or as an elastic pump. There may be various concerns depending on the characteristics of the material to collect the parts as they are without separating them from other plastic parts and reuse them as raw materials for the production of cosmetic accessories such as cosmetic containers and pumps. In order to reuse or reuse some parts, it will be inevitably necessary to separate and collect elastomeric and non-elastomer parts.

In addition, in the case of a conventionally provided push pump, a transfer path or communication hole for supplying liquid contents to a push button or a discharge cap is vertically formed in an open top form with respect to the side wall of the working piston rod or piston unit. As it is formed to communicate with the flow path in a horizontal state, it is difficult to manufacture a mold for the working piston rod or piston unit to form the transfer path or communication hole, and it takes a lot of time or money to manufacture, and the productivity of parts is low. There are structural problems, such as losing.

It may be configured to be integrally formed.

According to the present invention, it is formed by the corresponding outer circumferential surface of the connecting pipe body 52 provided in the second locking request 47a and the button 50 formed on the inner circumferential surface of the second assembly groove 47 of the second support pipe body 42 . The second locking frame 52a may be formed on opposite sides of each other by changing the position.

Accordingly, the button 50 coupled to the valve guide 40 has the above-described second locking request (47a) and second locking frame (52a) configuration and serrations (47b) and (52b) structures during the discharge operation. Through the assembly method, it may be operated under pressure together with the valve guide 40 , and may be rotated together during locking and unlocking operations, and may be forcibly separated from the valve guide 40 if necessary.

On the other hand, according to the present invention, when assembling the connecting tube body 52 of the button 50 with respect to the second assembly groove 47 formed inside the second support tube body 42 of the valve guide 40, they are not separated from each other. The configuration to be assembled so as not to be, the coupling configuration consisting of the second locking request (47a) and the second locking frame (52a) configuration and the serration (47b, 52b) structure described above may be an example, and the same There is no need to be limited to a specific structure as long as the coupling method can achieve the purpose, and of course, various assembly methods such as a screw coupling method or an adhesive method can be devised.

Next, a description will be given of the elastic support part 60 for the pressing operation of the button 50 according to the discharge of the contents with reference to FIG. 7 .

The elastic support part 60 replaces the spring function of the metal material used in the conventional push pump. In the present invention, as already mentioned above, only the pure PP plastic material is used to replace the spring function of the metal material. developed to do so. And the elastic support part 60 of the present invention composed only of PP plastic material, if the function can be achieved, various implementations other than the configuration mentioned below will be possible.

As one example, the elastic support part 60 of the present invention is interposed between the second support tube body 42 of the valve guide 40 and the housing cover 30 to help the button 50 elastically pressurize. may be composed of a hollow tubular body with an empty interior as a whole, and a first support part 61 on which the lower surface is seated on the upper surface of the support step 31 of the housing cover 30, and the first support part 61 ) is formed extending to the top of the upper elastic action point 63, and the cut thickness becomes thinner toward the upper elastic action point 63. When the pressing pressure of the button 50 is applied around the elastic action point, it is elastically compressed to open outward. The elastic acting part 64 that is elastically deformed to be restored at the same time, and the second supporting part 65 which is bent stepwisely inside the upper part of the elastic action point 63 and is supported on the support step 43 of the valve guide 40 . ) may be included.

In addition, an elevation guide groove 65a is further formed at a position coincident with the open groove 36 of the housing cover 30 on the inner circumferential surface of the second support part 65, so that when the button 50 is pressed, The locking and release operation rib 48 formed on the outer peripheral surface of the first support tube body 41 of the valve guide 40 may be configured to be guided in a stable manner.

On the other hand, according to the present invention, the elastic action portion 64 of the elastic support portion 60 is designed to be smaller than the inner diameter of the lifting guide 53 of the button 50 when the maximum compression diameter is deformed by compression. Preferably, only then can the lifting guide 53 of the button freely move up and down without any interference within the lifting guide 12 of the pump cap 10 .

Therefore, since the elastic support part 60 is interposed between the housing cover 30 and the support step 43 of the valve guide 40, when the button 50 is pressed, the valve guide moves downward integrally therewith. As it is forcibly pressed by (40) and at the same time as the elastic action part (64) is compressed around the elastic action point (63), which is formed thinly, it causes a deforming action that opens outward, and the button (50) When the pressing force is released, the valve guide 40 and the button 50 naturally and quickly move upwards by the return force of the elastic acting part 64 that has been elastically compressed to the outside.

In addition, the elastic support part 60 according to the present invention may be implemented differently as illustrated in FIG. 16 , the first support part 61 supported on the upper surface of the support step 31 of the housing cover 30 . and an elastic acting part 64 formed so as to be resilient to the upper part of the first support part, and a second support part 65 extending to the upper part of the elastic acting part, wherein the elastic acting part 64 is formed. may have a configuration in which the elastic action space 64a and the elastic action piece 64b are continuously and repeatedly formed along the circumference to enable the vertical and elastic action.

Here, although the elastic action space 64a and the elastic action piece 64b formed in the elastic action portion 64 are shaped like an “S” in the drawing, they are of a form such that the compression/elastic action is performed smoothly. , it is not necessary to be limited thereto, and if the button 50 is in a form capable of up-and-down elastic action when pressing, it will be possible to implement deformation in various forms.

In addition, according to the present invention, the elastic support portion 60 illustrated in FIG. 16 may be differently modified as shown in FIG. 17 .

That is, at the lower end of the first support part 61 of the elastic support part 60, one or more open grooves 36 as an inner circumferential surface, and a locking step 37 are formed between each of the open grooves, and the housing ( 20) may be configured to be integrally formed with the housing cover 30, which is cover-coupled to the open end of the temporary storage chamber 21 of the contents.

Here, the configuration of the housing cover 30, basically, FIG. 4 may be sufficiently referenced, and as it is integrally molded with the elastic support part 60, the omission of some configurations may be made. For example, the elastic request 34 and the second coupling part 35 in the form of being bent inwardly upward so as to be connected to each other through the lower connection part 33 and opened upwardly between them at the same time may be omitted. .

As illustrated in FIG. 17 , when forming the elastic support part 60 , the number of parts can be reduced by integrally injection-molding the housing cover 30 and the injection-injected separately into a single part, and mold manufacturing accordingly It may be possible to achieve a reduction in cost or assembly process.

As illustrated in FIGS. 16 and 7 , in the elastic support part 60 , the second support part 65 is supported on the lower surface of the second support tube body 42 of the valve guide 40 , so that the elastic pressing force for the button 50 is applied. It can be assembled to provide

As described above, the elastic support part 60 of the present invention shown in each embodiment can quickly and smoothly perform the elastic press operation of the button 50 through the elastic deformation action of the elastic action part 64 .

Referring to FIG. 8 , the valve 70 includes a piston rod 71 having an upper end inserted into the first assembly groove 44 formed in the first support tube body 41 of the valve guide 40 and assembled thereto, and the piston rod The piston support 72 provided at the lower end of the and the outer circumferential surface of the piston rod 71 to guide the contents of the temporary storage compartment 21 of the housing 30 to be discharged to the discharge hole 51 of the button 50 . It is configured to include one or more slit grooves 73 divided in the longitudinal direction.

According to the present invention, a slit groove 73 for inducing discharge of the contents of the temporary storage chamber 21 to the discharge hole 51 of the button 50 is formed in the longitudinal direction with respect to the outer circumferential surface of the piston rod 71 of the valve 70 . Compared to the conventional valve structure in which a discharge path is provided in the interior of the piston rod and a hole is formed to discharge the contents by forming a hole through it, the mold production of the valve 70 is very quick and easy, and the piston rod ( By improving the structure so that the slit groove 73 is formed in the longitudinal direction with respect to the outer circumferential surface of 62), mass production of the valve 70 is possible, as well as providing technical and economic advantages that enable the production of valves of superior quality can do.

The valve 70 is not arbitrarily separated from the first assembly groove 44 formed in the first support tube body 41 of the valve guide 40 so that the piston rod 71 is operated to be lifted and lowered together with the valve guide 40. It needs to be fitted in a forced assembly method to avoid it.

To this end, the present invention, as shown in Figure 13, the inner peripheral surface of the first assembly groove 44 formed in the first support tube body 41 of the valve guide 40 and the outer peripheral surface of the piston rod 71, After the valve 70 is assembled to the valve guide 40 by forming the third locking frame 44a and the third locking groove 71a correspondingly and coupling them to each other in a forced locking manner, they are arbitrarily mutually exclusive. It can be configured to prevent separation.

At this time, the third locking frame 44a formed on the inner peripheral surface of the first assembly groove 44 formed in the first support tube body 41 and the third locking groove 71a formed on the outer peripheral surface of the piston rod 71 are It may be formed on the opposite side by changing the positions of each other.

And, the configuration of the third locking frame 44a and the third locking groove 71a provided in the present invention to prevent arbitrary separation and separation of the valve 70 with respect to the valve guide 40 is an example It may be, and as long as it is a coupling method capable of achieving the same purpose, it is not necessary to be limited to a specific structure, and of course, various assembly methods such as a screw coupling method may be devised.

9, the piston 80 is interposed between the valve guide 40 and the valve 70 to provide a downward compressive force in the temporary storage chamber 21 of the contents when the contents are discharged, and is opened by the downward movement deviation. This allows the contents to be discharged through the gap between the upper gap of the piston support 72 of the valve 70 and the slit groove 73 of the piston rod 71, and in the case of non-discharging, the contents are temporarily stored from the container 100 in reverse. (21) will provide a suction force to force the contents to be sucked.

To this end, the piston 80 is configured to include an inner wall 81 and an outer wall 82 formed at a predetermined distance to the outside with respect to the inner wall, and the inner wall 81 is the piston rod 71 . The lower end (81a) of which is fitted on the outer circumferential surface is seated and supported on the upper surface of the piston support (72), and the upper end (81b) of the first support tube body (41) of the valve guide (40) is formed as an inner circumferential surface of the lower end of the elevating guide. It is coupled to provide an elevating working space P between the grooves 45, and the outer wall 82 is coupled so as to be in elastic close contact with the inner circumferential surface of the temporary storage compartment 21 of the housing 20. (See FIG. 1) )

Accordingly, the piston 80 is coupled so that the inner wall 81 is fitted to the piston rod 71, the lower end 81a is seated and supported on the piston support 72, and the upper end 81b is the valve guide. (40) As a part of the second support pipe body 41 is coupled in a state where a part is fitted through the elevating guide groove 45 which is extended and formed to the inner circumferential surface of the lower end, the elevating operation space P is provided. , before the button 50 is pressed, the slit groove 73 formed in the piston rod 72 of the valve 70 is always blocked by the lower end of the inner wall 81 that is in close contact with the upper surface of the piston support 72, In addition, only when the button 50 is pressed to discharge the contents, the piston 80 descends later than the piston rod 71 of the valve 70 by the lifting working space P due to the descending movement deviation. As the lower end 81a of the inner wall 81, which was in close contact with the upper part of the piston support 72, is spaced apart, the contents can be discharged through the gap and the slit groove 73 of the piston rod 71. . (see Figures 1 and 15)

Meanwhile, according to the present invention, the inner wall 81 lower end 81a of the piston 80 seated on the piston support 72 of the valve 70 has a slit groove 73 formed on the outer peripheral surface of the piston rod 71 . ) can be supported in a multiple airtight structure with respect to the piston bearing 72 in order to provide high airtightness.

To this end, in the present invention, as shown in FIG. 14 , a wedge-shaped airtight support groove 72a is further formed as the piston support 72 of the valve 70, and the airtight support groove 72a is The inner wall 81 of the piston 80 is configured such that the lower end 81a is supported in a multi-adherence state to provide high airtightness to the slit groove 73 of the piston rod 71 .

In more detail, as the airtight support groove 72a formed of the piston support 72 is formed in a wedge groove shape, the inner wall 81 lower end 81a of the piston 80 fitted thereto is at least the bottom surface and both ends thereof. Since parts of both sides adjacent to each other, including corners, are supported in a state of being in close contact with each other, multiple contact support is possible.

Referring to FIG. 10 , the backflow prevention disk 90 is coupled to open and close the contents inlet hole 22 formed in the bottom of the contents temporary storage chamber 21 of the housing 20, and the backflow prevention disk is a unidirectional disk. As an example, when the contents in the container 100 are introduced into the temporary contents storage chamber 21 of the housing 20 through the contents inlet hole 22 and the backflow prevention disk, the liquid contents flow back into the container 100 again. ) has a structure that cannot be entered, and through this, when the button 50 is pressed, the discharging action of the contents stored in the contents temporary storage chamber 21 can be made smoothly.

Each component of the push pump 1 according to the present invention configured as described above is assembled as shown in FIG. 1 , and may be used in combination with the inlet 110 of the container 100 .

At this time, the push pump 1 made of only PP plastic material, in the product distribution process, for example, before the product is finally supplied to the consumer and used, the button 50 is arbitrarily pressed to prevent the contents from being discharged to the outside. , The locking and unlocking operation rib 48 formed on the first support tube body 41 of the valve guide 40 coupled to the button 50 is among the locking steps 37 of the housing cover 30, in particular, the horizontal support surface. The button 50 is rotated and assembled to the closed position so that it is supported by (37a). In this case, the closed position of the button may be appropriately displayed on the upper surface of the button. Then, the button 50 is prevented from being arbitrarily pressed by the locking support of the locking and releasing operation rib 48 during the distribution process, and at the same time, arbitrary discharge of the contents can also be prevented. (See FIG. 11 )

And, when assembling the push pump 1 made of only PP plastic material, the inner wall 81 of the piston 80 has an upper end 81a of the piston rod 71 and the first support tube body of the valve guide 40 ( 41) The elevating operation space (P) is inserted into the elevating guide groove (45) formed by the inner peripheral surface of the lower end and assembled in a state in which it is provided.

In addition, the elastic support part 60 interposed between the valve guide 40, the support step 43 and the housing cover 30 maintains the state in which the elastic action part 64 is extended to the maximum, through which the valve The valve 70 in which the piston valve 71 is fitted inside the first assembly groove 44 of the first support tube body 41 of the guide 40 maintains a state of moving upward of the temporary storage chamber 21 of the contents. At the same time, the piston 80 also maintains the upwardly supported state, and at this time, the inner wall 81 of the piston 80, the lower end 81a blocks the upper surface of the piston support 72, so the piston Discharge of the contents is prevented through the slit groove 73 of the rod 71 .

Therefore, in the product equipped with the push pump 1 made of only the PP plastic material of the present invention, in the distribution process, as described above, the button 50 has the valve guide 40 against the locking step 37 of the housing cover 30 . ), since the locking and release operation ribs 48 formed on the first support tube body 41 are stably supported and maintained in a locked state, discharging of the contents is not possible.

A state in which a consumer purchases a product and uses the product by discharging the contents to the outside in this state will be described with reference to FIG. 15 as follows.

First, in order to discharge the contents, the button 50 assembled in the locked state is rotated to the open position. In this case, the open position of the button may also be appropriately displayed on the upper surface of the button. When the button 50 is rotated to the open position as described above, the valve guide 40 and the elastic support 60 integrally coupled thereto, or the valve 70 coupled to the valve guide 40, It is rotated in the same direction, and at the same time, the locking and unlocking operation rib 48 formed on the first support tube body 41 of the valve guide rotates along the locking step 37 of the housing cover 30, while the opening groove 36 ) is moved to position.

When the button 50 is pressed in this state, the valve guide 40 coupled to the first support tube body 41 of the button moves downward, and at the same time, the piston moves against the first support tube body 41 of the valve guide. The valve 70 to which the rod 71 is coupled also moves downward. In addition, when the button is pressed, the elastic support part 60 interposed between the support step 43 of the valve guide 40 and the housing cover 30 is also elastically operated so as to open outward. That is, the elastic action portion 64 of the elastic support portion 60 undergoes an elastic deformation in which the lower end is gradually opened outwardly and compressed around the elastic action point 63 having a thin thickness. And, in the process of the piston rod 71 of the valve guide 40 and the valve 70 moving downward together, the piston 80 is provided inside the lower end of the first support pipe 41 of the valve guide 40 When the upper end 81b of the inner wall 81 is fitted with respect to the elevating guide groove 45, since the elevating working space P is provided in the state where it is fitted, the valve guide 40 by the elevating working space P. It does not move downward until the first support pipe body 41 of the first support pipe 41 is moved downward and forcibly moved, that is, since it has a downward movement deviation as much as the lifting working space P, the piston support of the valve 70 ( 72) A gap is generated between the upper surface and the upper surface of the piston support 72 that has been blocked by the inner wall 81 of the piston 80 and the lower end 81a. In this state, the valve 70 and the piston 80 move downward together, and in this process, the outer wall 82 of the piston 80 is in elastic contact with the inner circumferential surface of the content temporary storage chamber 21 in which the content is stored. The contents are compressed while moving, and the contents stored in the contents temporary storage chamber 21 through the downward compression action of the piston 80 are opened according to the deviation of the downward movement distance of the piston 80 . The contents are introduced into the gap on the upper surface of the piston support 72 of the piston rod 71, and are discharged through the slit groove 73 formed on the outer peripheral surface of the piston rod 71, and the contents discharged and moved through the slit groove 73 are 40) is discharged to the outside through the through hole 46a formed in the partition wall 46, the connector body 52 of the button 50, and the outlet hole 51 of the button 50 connected to the connector body 52, will lose

In addition, when the discharging of the contents is completed and the press on the button 50 is released, the elastically acting part 64 of the elastic support part 60, which was elastically deformed in a compressed state, quickly returns to its original state by its own elastic force. The button 50, the valve guide 40, and the valve 70 are simultaneously moved upward by the elastic restoring force of the elastic action part, and the piston 80 is also forcibly upward by the upward movement of the valve. As it moves, the slit groove 73 is blocked by the lower end 81a of the inner wall 81 being in close contact with the upper surface of the piston support 72 of the valve 70 . And according to the upward movement of the piston 80, a suction force is generated in the interior of the contents temporary storage chamber 21 according to the rise of the piston, and the contents contained in the container through the suction force are transferred to the contents inlet hole 22 and countercurrent flow. The contents are forcibly sucked into the temporary storage chamber 21 through the prevention disk 90 . The suction process of the above-described contents is performed until the button 50 is released and the elastic action part 64 of the elastic support part 60 returns to its original position.

On the other hand, in the process of discharging the contents, the button 50, the valve guide 40, and the valve 70 have a locking and unlocking operation rib 48 formed on the outer circumferential surface of the first support tube body 41 of the valve guide 40 in the housing. As it moves up and down along the open groove 36 formed vertically on the inner circumferential surface of the second coupling part 35 of the cover 30, a stable discharge operation of the contents is possible.

Therefore, according to the push pump 10 made of only the PP plastic material according to the present invention, the elastic support unit 60 performs an elastic deformation action in conjunction with this by providing or releasing a pressing force to the button 50 . The button 50, the valve guide 40, the valve 70, and the piston 80 move up and down through the elastic deformation action of the elastic support part 60 to store the contents of the temporary storage compartment 21. It becomes possible to continuously and repeatedly discharge one time or several times, and at the same time, it is possible to forcibly suck the contents stored in the container 100 into the contents temporary storage chamber 21 of the housing 20 .
