Description

Elastic member for pump dispenser {ELASTIC MEMBER FOR PUMP DISPENSER}

The present disclosure relates to an elastic member for a pump dispenser, and more specifically, to an elastic member made of a non-metallic material that is mounted inside a pump dispenser and provides uniform elastic restoring force in the same manner as the spring function of an existing metal material.

In general, a pump dispenser is a device that discharges a certain amount of gas, liquid, or other contents charged inside a sealed container by pressurizing it, and is used for various purposes such as storing cosmetics, perfume, medicine, and food. It is applied to airtight containers.

When a user applies an external force to the pump dispenser, the contents inside the container combined with the pump dispenser may be discharged to the outside. Meanwhile, the pump dispenser is equipped with a spring, so that when the user's external force is released, the deformed pump dispenser can be restored to its initial state.

However, the spring is made of metal material. Therefore, if you want to recycle the pump, a separate process is required to separate the metal spring present in the pump. However, because the structure of the pump is complex, there is a problem that it is difficult for the user to separate the metal spring present in the pump.

Therefore, the definition should be made based on the contents throughout this specification.

In terms of recycling, it may be better to use non-metallic elastic members in pump dispensers instead of metallic springs. However, an elastic member made of a non-metallic material may have difficulty providing sufficient elastic restoring force, and an elastic member made of a non-metallic material that provides sufficient elastic restoring force may have too strong an elastic restoring force to be deformed only when a strong external force is applied. In this case, there may be a problem that the user of the pump dispenser must press the pump dispenser strongly to discharge the contents to the outside for the pump dispenser to operate. In order to solve the above-mentioned problems, the elastic member made of non-metallic material needs to have a special structure. This will be explained in detail below.

1 is a perspective view of an elastic member for pump dispensing according to some embodiments of the present disclosure. Figure 2 is a perspective view for explaining an example of a pump dispenser using an elastic member according to some embodiments of the present disclosure. FIG. 3 is a cross-sectional view taken along line A-A' of FIG. 2.

FIGS. 2 and 3 are diagrams showing an example of a pump dispenser in which the elastic member shown in FIG. 1 is used. Accordingly, the elastic member shown in Figure 1 can be used in the pump dispenser shown in Figures 2 and 3, but can also be used in pump dispensers other than the pump dispenser shown in Figures 2 and 3. In addition, the elastic member shown in FIG. 1 may be disposed in a position different from the position shown in FIGS. 2 and 3.

The elastic member 400 of the present disclosure can be used in a pump dispenser. Here, a pump dispenser is a device that discharges a certain amount of gas, liquid, or other contents charged inside a sealed container by pressurizing it, and is applied to various sealed containers that store cosmetics, perfume, medicine, and food. can do. However, it is not limited to this.

The elastic member 400 may be made of a non-metallic material that has elastic restoring force in compression or tension. Here, the elastic member 400 may be formed of one of plastic, rubber, or thermoplastic elastomer. However, it is not limited to this.

The plastic material may include at least one of polypropylene (PP), polyethylene (PE), ethylene-vinyl acetate copolymer (EVA), polyvinyl chloride (PVC), and polyurethane (PU). However, it is not limited to this.

The rubber material is a chemically crosslinked polymer and may include at least one of natural rubber and synthetic rubber. Here, the synthetic rubber may include styrene-butadiene rubber. However, it is not limited to this.

Thermoplastic elastomers can be molded like plastics that become flexible at high temperatures, and can be polymer materials that exhibit the properties of rubber elastomers at room temperature. Accordingly, the elastic member 400 can have restoring force by using a thermoplastic elastomer that exhibits the properties of a rubber elastomer at room temperature. Specifically, thermoplastic elastomer is a polymer material that exhibits rubber elasticity under usage conditions and can be molded like thermoplastic plastic under certain molding conditions. However, it is not limited to this.

Depending on the material used, thermoplastic elastomers are classified into Styrene-based (thermoplastic styrenic block copolymer, SBC), Olefin-based (thermoplastic olefinic elastomer, TPO), urethane-based (thermoplastic polyurethane, TPU), amide-based (thermoplastic polyamide, TPAE), and polyester-based (thermoplastic polyester). elastomer, TPEE), etc. However, it is not limited to this.

According to some embodiments of the present disclosure, the elastic member 400 made of polypropylene (PP) may provide the most appropriate elastic restoring force. Specifically, the elastic member 400 made of PP not only operates the pump dispenser more easily than an elastic member made of other materials having the same shape and shape, but also provides sufficient elastic restoring force.

Referring to FIG. 1, the elastic member 400 may include an upper ring 410, a lower ring 410, and a plurality of connection rings 430. However, the above-described components are not essential for implementing the elastic member 400, and the elastic member 400 may have more or fewer components than the components listed above.

The upper ring 410 may refer to a ring-shaped plate formed on the upper part of the elastic member 400. The lower ring 420 may refer to a ring-shaped plate formed at the lower part of the elastic member 400.

According to some embodiments of the present disclosure, the upper ring 410 and the lower ring 410 may have a central hole through which the central portion of the stem (320 in FIG. 3) passes. The size and shape of the inner peripheral surface of the upper ring 410 and the lower ring 410 (size and shape of the central hole) may correspond to the size and shape of the outer peripheral surface of the central portion of the stem (320 in FIG. 3). Accordingly, the central portion of the stem 320 may penetrate the central hole of the upper ring 410 and the lower ring 410.

The upper ring 410 may be disposed below the force transmission member protruding outward along the outer peripheral surface at the upper part of the central portion of the stem 320. And, the lower ring 420 may be seated on the seating member 331 that protrudes inward from the lower part of the chapel 330. Here, the seating member 331 may be a component that does not move and is not affected by the external force even when external force is applied to the pump dispenser. Therefore, when the stem 320 is lowered by an external force, the external force is transmitted to the upper ring 410 and the upper ring 410 may descend, but the lower ring 420 may not descend.

Meanwhile, when the upper ring 410 descends, the lower ring 420 does not descend, so strain may be applied to the plurality of connecting rings. In this case, the plurality of connecting links 430 may try to return to their original shape by elastic restoring force. Accordingly, the plurality of connection rings 430 may push the upper ring 410 upward when the external force applied to the pump dispenser is released. When the plurality of connection rings 430 push the upper ring 410 upward, force may be transmitted to the force transmission member of the stem (320 in FIG. 3). In this case, the pump dispenser may return to the state before external force was applied to the pump dispenser.

The plurality of connection rings 430 are in the form of a ring having a structure that provides elastic restoring force in compression or tension while connecting the upper ring 410 and the lower ring 420 between the upper ring 410 and the lower ring 420. It may mean multiple plates.

Since each of the plurality of connection rings 430 has a ring-shaped plate, it may be provided with a central hole. Here, the central portion of the stem (320 in FIG. 3) of the pump dispenser may pass through the central hole. However, it is not limited to this, and other components of the pump dispenser may pass through the central hole.

The size and shape of the inner peripheral surface of each of the plurality of connection rings 430 (size and shape of the central hole) may correspond to the size and shape of the outer peripheral surface of the central portion of the stem 320. Accordingly, the central portion of the stem 320 may penetrate the central hole of the upper ring 410 and the lower ring 410.

When the stem penetrates the central hole provided in each of the upper ring 410, the lower ring 420, and the plurality of connecting rings 430, the upper ring 410, the lower ring 420, and the plurality of connecting rings 430 ) can provide elastic restoring force to the pump dispenser while being fixed inside the pump dispenser by the stem 320.

The plurality of connection rings 430 may be connected in a zigzag manner between the upper ring 410 and the lower ring 420. Accordingly, the plurality of connecting links 430 may provide elastic restoring force in compression or tension.

Specifically, among the plurality of connection rings 430, two adjacent connection rings are connected at each end so as to be inclined to each other, and the continuous connection rings are connected to one side A in the width direction of the elastic member 400 and the other side in the width direction of the elastic member 400. They can be connected alternately in (B). Therefore, a space is formed between successive connecting links, so that compression by external pressure can be smoothly performed. In other words, this connection structure of a plurality of linkages can prevent the elastic restoring force from being too strong.

Meanwhile, a first elastic restoring force strengthening portion may be provided at a portion of the plurality of connection rings 430 where two adjacent connection rings are connected. The first elastic restoring force strengthening portion may strengthen the elastic restoring force while providing a function of combining two adjacent connecting links.

Specifically, each of the plurality of connection rings 430 is coupled to each other, and the portion where each of the plurality of connection rings 430 is coupled to each other may be reinforced with the same material as the plurality of connection rings 430. Here, the reinforced portion may be the first elastic restoring force reinforcement portion. Accordingly, the portion where the plurality of connection rings 430 are connected to each other may be thicker than other portions due to the first elastic restoring force strengthening portion.

For example, two adjacent connection rings among the plurality of connection rings 430 may be coupled to each other through a first elastic restoring force reinforcing portion at each end so as to be inclined to each other. In addition, the continuous connecting rings may be alternately connected through the first elastic restoring force reinforcement portion at one side (A) in the width direction of the elastic member 400 and the other side (B) in the width direction of the elastic member 400.

Even when the plurality of connecting links 430 have a structure in which they are simply combined, elastic restoring force can occur. In this case, the elastic restoring force may have a force that is not sufficient to return the pump dispenser to its original state when the external force on the pump dispenser disappears. However, as in the present disclosure, when a first elastic restoring force reinforcing part is further provided at a portion where two adjacent connecting links among the plurality of connecting links 430 are connected, the elastic restoring force may be increased. In this case, the elastic restoring force may have a force sufficient to return the pump dispenser to its original state when the external force on the pump dispenser disappears.

Meanwhile, among the plurality of connection rings 430, the first connection ring connected to the upper ring 410 may be coupled to the upper ring 410 through the second elastic restoring force strengthening portion. In addition, the second connection ring connected to the lower ring 420 among the plurality of connection rings may be coupled to the lower ring 420 through the third elastic restoring force strengthening portion. Accordingly, the elastic restoring force of the elastic member 400 can be further strengthened.

On the other hand, when the upper ring 410 and the lower ring 410 are formed of a non-metallic material with elastic restoring force, the pressure applied to the elastic member 400 will be partially absorbed by the upper ring 410 and the lower ring 410. You can. Therefore, damage such as breaking or cracking of the elastic member 400 (e.g., the upper ring 410, the lower ring 420, and the plurality of connecting rings 430) is prevented by excessive external pressure. It can be prevented.

In addition, a through hole through which at least a portion of the stem 320 passes is formed in the plurality of connection rings 430, and the plurality of connection rings 430 may have the same shape and size. Accordingly, the plurality of connection rings 430 may be connected to each other at a constant angle. In other words, the plurality of connecting rings 430 can be compressed more smoothly and have high elastic restoring force compared to elastic bodies with structures where the angles of the connected parts are different due to their different shapes and sizes.

Meanwhile, when the elastic member 400 has a structure as described above in FIG. 1, the discharge portion (300 in FIG. 3) can be prevented from rotating when the stem is lowered by an external force. Therefore, users can use the pump dispenser more conveniently. In addition, in order to secure an appropriate elastic restoring force, it is recommended to make the elastic member 400 long, but since the length of the elastic member 400 cannot be made infinitely long, the structure described above in FIG. 1 secures the stroke and provides elastic restoring force. This may be the best structure to appropriately provide.

In addition, when the elastic member 400 has a structure as described above in FIG. 1, twisting is prevented when the pump dispenser operates, thereby providing more stable and uniform elastic restoring force.

Meanwhile, a dip tube (not shown) may be fastened to the transmission unit 200. Additionally, the dip tube (not shown) may deliver the contents contained in the container to the inside of the housing 100 (for example, the second space 120) through the delivery unit 200. Specifically, the dip tube (not shown) is in the form of a tube of a certain length, one end of which is placed in the lower part of the housing 100, and the other end of which is placed inside the container to transfer the contents contained in the container to the inside of the housing 100. You can.

The discharge unit 300 may include an actuator 310, a stem 320, a chaplet 330, a gas cat 340, a closure 350, a sub-stem 360, and a piston 370.

The discharge unit 300 is coupled to the upper part of the housing 100, and some of the components included in the discharge unit 300 (for example, the actuator 310) move up and down by external pressure to move the housing 100. ) can be discharged to the outside.

The discharge unit 300 may be made of plastic material. For example, plastic materials include HDPE (High-Density Polyethylene), PVC (Polyvinyl Chloride), PP (Polypropylene), PE (Polyethylene), ABS (Acrylonitrile Butadiene Styrene Copolymer), and PC-ABS (Polycarbonate-Acrylonitrile Butadiene Styrene Copolymer). and EVA (Ethylene-Vinyl Acetate Copolymer).

Here, the second passage 311a may be connected to the first passage 321 of the stem 320, which will be described later. In this case, the first passage 321 and the second passage 311a may be passages through which contents are moved. Meanwhile, the second passage 311a may be formed vertically, that is, in the longitudinal direction, so that the contents move from the bottom to the top through the first passage 321.

Additionally, the lower portion of the chapel 330 may include a seating member 331 protruding inward. Here, the lower portion of the elastic member 400 may be seated on the upper side of the seating member 331. Therefore, when the actuator 310 and the stem 320 are lowered by external pressure, the lower part of the elastic member 400 does not descend due to the seating member 331 of the chapel 330, but the elastic member 400 Only the upper and middle sections can be descended. Accordingly, when compression is achieved and the external pressure disappears, the elastic member 400 is tensioned and moves at least one component of the discharge portion 300 (e.g., the actuator 310 and the stem 320) by the elastic restoring force. It can be placed in the position before external pressure is applied. Additionally, the seating member 331 can prevent the inserted stem 320 from descending beyond a certain depth. Specifically, when the actuator 310 and the stem 320 are lowered to a certain depth by external pressure, the guard member 313 of the actuator 310 is caught by the seating member 331 of the chapel 330 and the stem 320 It is possible to prevent descending beyond a certain depth in this downward direction.

Meanwhile, the gasket 340 is formed in a ring shape and may be coupled to the upper outer peripheral surface of the chapel 330 to provide packing between the chapel 330 and the closure 350. Additionally, the gas cat 340 may have a gas cat coupling portion formed on the outside to be coupled to the closer 350. Specifically, the gas cat coupling portion may mean a portion in which the lower area of the gas cat 340 is formed to be larger than the upper area and a ledge is formed between the upper and lower parts.

Meanwhile, the closure 350 is in the form of an empty cylinder, and the upper part is formed to cover the outer peripheral surface of the gas cat 340 and the upper part of the chapel 330, and the lower part is inwardly spaced at a certain distance from the housing 100. It may be provided to be spaced apart. Accordingly, the container can be coupled to the space formed apart from the housing 100. However, the location where the containers are combined is not limited to this.

Meanwhile, the sub stem 360 is coupled to the lower part of the stem 320 and can move up and down by external pressure. Additionally, the substem 360 may have a first seating groove 361 formed on the inside of the lower side. According to some embodiments of the present disclosure, the sub-stem 360 may have a hollow interior and the sub-stem flow path through which contents are moved may be formed by penetrating the sub-stem 360 in the longitudinal direction. Accordingly, the sub-stem 360 can move up and down by external pressure and transfer the contents inside the housing 100 to the stem 320 through the sub-stem flow path.

Meanwhile, the inside of the piston 370 may be in close contact with the outer peripheral surface of the sub-stem 360, and the outside of the piston 370 may be in close contact with the inner wall of the housing 100. Accordingly, the piston 370 can separate the interior of the housing 100 into the first space 110 and the second space 120. Specifically, in the internal space of the housing 100, the space above the piston 370 may be the first space 110, and the space below the piston 370 may be the second space 120. And the piston 370 can prevent the contents of the second space 120 from moving into the first space 110. Additionally, the piston 370 can move the contents up and down by the sub-stem 360 by changing the pressure inside the housing 100 to move the contents.

Meanwhile, the contents contained in the container connected to the delivery unit 200 are delivered to the interior of the housing 100 (e.g., the second space 120), and the contents delivered to the interior of the housing 100 are delivered to the discharge unit ( In order to discharge to the outside through 300, a change in pressure inside the housing 100 is required. Specifically, as a part of the discharge unit 300 is lowered due to external pressure, the space inside the housing 100 narrows, and the pressure inside the housing 100 increases, so that the contents contained inside the housing 100 are discharged into the discharge unit ( 300) and is discharged to the outside. Then, when the lowered part of the discharge unit 300 is raised to its original position, the pressure inside the housing 100 decreases and the contents contained in the container are transferred to the housing 100 along the dip tube (not shown) of the delivery unit 200. moved inside. Therefore, it is important to smoothly move a portion of the discharge portion 300 up and down inside the housing 100. According to some embodiments of the present disclosure, the pump dispenser can smoothly move a portion of the discharge unit 300 up and down through the elastic member 400.

The elastic member 400 may be disposed at least partially in the first space 110 and may be provided to surround at least a portion of the outer peripheral surface of the stem 320 . Specifically, the upper part of the elastic member 400 may be provided on the upper part of the stem 320, and the lower part may be seated on the upper side of the seating member 331 of the chapel 330. Therefore, when the stem 320 is lowered by external pressure, the upper and middle portions of the elastic member 400 descend together with the stem 320, and the lower portion of the elastic member 400 is a seating member of the chapel 330. It may not descend by (331).

Meanwhile, when pressure is applied downward through the actuator 310 connected to the stem 320 and the pressure is released, the elastic member 400 moves at least one component of the discharge portion 300 (for example, , the actuator 310, stem 320, sub-stem 360, and piston 370) can be positioned at the position before pressure is applied. Accordingly, the elastic member 400 may be configured to smoothly perform compression or tension. A detailed description of this will be provided later with reference to FIG. 3 .

As in some embodiments described above in FIGS. 1 to 3, the pump dispenser includes an elastic member 400 made of a non-metallic material with elastic restoring force instead of a metal spring, so that it can be easily recycled without separation. Additionally, the pump dispenser is provided with a guard member 313 of the actuator 310, and an elastic member 400 is disposed in the first space where contents are not delivered. Accordingly, external foreign substances and contents are prevented from contacting the elastic member 400, and the elastic restoring force of the elastic member 400 can be maintained.
