Conventionally, a typical pump dispenser uses a method in which when a user pressurizes the pump head, the contents stored in the container are discharged to the outside through a nozzle placed on the pump head.

However, in this method, there is a problem that when the user presses the pump head and the pump head rises again and returns to its original position, the contents remaining inside the nozzle are gradually exposed to the outside or flow out.

Also, if the contents of the container are in the form of liquid, emulsion, cream, etc., the contents outside the nozzle's discharge port may be exposed to the air and harden as moisture evaporates. In this case, when the user uses the contents after the next pump, especially in the case of cosmetics, the hardened part must be removed and applied to the skin or face, which causes discomfort to the user and causes the contents to be wasted.

In addition, conventional pump dispensers are made of plastic, and when recycling them, they are melted down and made into different forms. However, if metal materials such as springs are mixed inside the pump dispenser, they must be removed and go through a recycling process. However, since most pump dispensers have a small and compact structure, there is a problem in that it is not easy to separate only these metal materials for the recycling process.

Here, the elastic support portion 744 may be formed between the holder body 741 and the deformable portion 745, and may be made of the same hard plastic material as the holder body 741.

The holder flange 743 may be disposed to protrude around the outer circumference of the holder body 741 and may be inserted into a fixing groove formed on the inner surface of the nozzle passage 227. Accordingly, the holder body 741 can be fixed to the inner surface of the nozzle passage 227. The holder flange 743 may also be made of the same hard plastic material as the holder body 741.

The deformable portion 745 may be disposed around the inner circumference of the holder body 741 and may be deformed by the discharge pressure of the pumping object. This deformable portion 745 may be made of a plastic material that is more ductile than the holder body 741, and may have a degree of ductility that can be sufficiently deformed by the discharge pressure of the pumping object.

Additionally, at least one incision part 747 may be formed in the deformation part 745, and the deformation part 745 may be cut into multiple pieces.

Referring to the enlarged view of FIG. 3A, the state before the deformation portion 745 is deformed is disclosed. Before the deformation part 745 is deformed, the outer end of the deformation part 745 is connected to the inside of the holder body 741, and the inner end of the deformation part 745 is close to the outer circumference of the opening and closing beam 715. there is.

And the cut portion 747 is formed from the outer end to the inner end of the deformation portion 745. In the embodiment of the present disclosure, four incisions 747 are formed, but this is not necessarily limited, and may be formed in different numbers depending on the size and thickness of the deformation portion 745.

Referring to the enlarged view of Figure 3b, as the user presses the head body 210 with force F, the head body 210 descends inside the upper receiving part 311, and the pumping part 400 described above By the operation of the pumping object moves from the stem passage 417 to the head passage 211, and the opening and closing member 700 opens the nozzle passage 227 by the discharge pressure of the pumping object moving to the head passage 211. You can check the status.

Due to the discharge pressure of the pumping object, the opening/closing head 710 is pushed backward as shown by the arrow A0, and the opening/closing beam 715 comes out of the valve holder 740.

The pumping object passes through the nozzle passage 227 and applies discharge pressure to the deformation portion 745. Then, the deformation part 745 is bent and deformed in an outward direction as shown in FIG. 3b, and the pumping object is discharged to the outside into the space between them as indicated by arrow A1.

At this time, the deformation portion 745 opens on both sides as shown by arrow A2 based on the incision portion 747 to form a space through which the pumping object can be discharged.

Afterwards, when the user withdraws the force (F), the stem 410 and the head body 210 move upward due to the elastic restoring force of the pumping spring 450, and the discharge pressure of the pumping object weakens, opening and closing in the state shown in Figure 3a. The member 700 is returned to its original position.

At this time, since the deformed portion 745 is also not subjected to discharge pressure, the shape that is bent outward and spread along the cut portion 747 returns to its original position, and the inner end of the deformed portion 745 is located around the outer circumference of the opening and closing beam 715. becomes closely attached to.

Through this, it is possible to prevent the pumping object remaining in the nozzle passage 227 from leaking out. Additionally, by preventing the pumping object remaining in the nozzle passage 227 from being exposed to the air, it is possible to prevent or alleviate the problem of hardening due to evaporation of moisture, etc.

Referring to FIGS. 1 and 5 to 8, the second embodiment of the pump dispenser 100 according to the present disclosure includes a head portion 200, a nozzle portion 220, a closure 300, a pumping portion 400, It may include a pump body portion 500 and an opening and closing member 700.

Since the description of the head part 200, nozzle part 220, closure 300, pumping part 400, and pump body part 500 is the same as the above-described first embodiment, the following description will be omitted.

Hereinafter, the opening and closing member 700 according to the second embodiment of the present disclosure will be described.

The opening and closing member 700 is disposed inside the nozzle unit 220 and can open and close the nozzle unit 220 by the discharge pressure of the pumping object.

The opening and closing member 700 according to the second embodiment of the present disclosure may include an opening and closing head 710 and an opening and closing unit 750.

The opening and closing head 710 is disposed inside the nozzle passage 227 and can open and close the nozzle passage 227 by contacting or separating from the support piece 225.

Here, a tapered portion 225a whose cross-sectional area is gradually reduced may be formed at one end of the support piece 225, and a connection passage connecting the nozzle passage 227 and the head passage 211 may be formed at the center of the support piece 225. (223) can be formed. Additionally, the opening/closing head 710 may have a hemispherical shape, and the hemispherical shape of the opening/closing head 710 contacts or separates from the tapered portion 225a, thereby opening and closing the nozzle passage 227 and the head passage 211.

The opening and closing unit 750 is connected to the opening and closing head 710 and applies an elastic force to the opening and closing head 710, and a through hole through which the pumping object moves may be formed inside.

The opening/closing unit 750 according to an embodiment of the present disclosure may be formed of a non-metallic material having elastic restoring force in compression or tension. Here, the opening/closing unit 750 may be made of one of plastic, rubber, or thermoplastic elastomer.

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. Therefore, the opening/closing unit 750 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 opening and closing unit 750 made of polypropylene (PP) can provide the most appropriate elastic restoring force. Specifically, the opening and closing unit 750 made of PP not only operates the opening and closing head 710 more easily than the opening and closing unit 750 made of other materials having the same shape and shape, but also provides sufficient elastic restoring force.

The opening and closing unit 750 according to an embodiment of the present disclosure may include a first ring 751, a second ring 753, a ring flange 754, a connecting ring 755, and an elastic reinforcement portion 757. . However, the above-described components are not essential for implementing the opening and closing unit 750, and the opening and closing unit 750 may have more or fewer components than the components listed above.

The first ring 751 may be a ring-shaped plate, and may be connected to the opening/closing head 710 with a link beam 752, and a through hole 751a may be formed in the central portion.

The second ring 753 may be a ring-shaped plate and is placed in close contact with the inner circumference of the nozzle passage 227, and a through hole 753a may be formed in the central portion.

The ring flange 754 is disposed around the outer circumference of the second ring 753, is inserted into the fixing groove 223a formed in the nozzle passage 227, and can fix the opening unit to the inside of the nozzle passage 227.

The connecting ring 755 may be a ring-shaped plate, and a plurality of rings may be stacked and connected in a zigzag manner between the first ring 751 and the second ring 753, and a through hole 755a may be formed in the central portion. . This link 755 can provide elastic restoring force to the opening and closing head 710, which is compressed or stretched depending on the discharge pressure of the pumping object.

Specifically, among the plurality of connecting rings 755, two adjacent connecting rings 755 are connected at each end so as to be inclined to each other, and the continuous connecting ring 755 is connected to one side in the width direction of the opening and closing unit 750 and the opening and closing unit. It can be connected alternately on the other side of the width direction of (750). Accordingly, a space is formed between the consecutive connecting rings 755, so that compression by external pressure can be smoothly performed. In other words, this connection structure of the plurality of connection rings 755 can prevent the elastic restoring force from being too strong.

In addition, the plurality of connecting rings 755 are formed with through holes 755a, and the plurality of connecting rings 755 may have the same shape and size. Accordingly, the plurality of connecting rings 755 may be connected to each other at a constant angle. That is, the plurality of connecting rings 755 can be compressed more smoothly and have high elastic restoration force compared to the elastic body 730, which has a structure where the angles of the connected parts are different due to different shapes and sizes.

Additionally, when the plurality of connecting rings 755 have the structure described above, twisting can be prevented and more stable and uniform elastic restoring force can be provided.

One or more elastic reinforcement parts 757 may be disposed between adjacent links among the plurality of links 755. The elastic reinforcement portion 757 can combine adjacent links and at the same time strengthen the elastic restoring force between adjacent links.

Specifically, each of the plurality of connecting rings 755 is coupled to each other, and the portion where each of the plurality of connecting rings 755 are coupled to each other may be reinforced with the same material as the plurality of connecting rings 755. Here, the reinforced portion may be the elastic reinforcement portion 757. Accordingly, the portion where the plurality of connecting rings 755 are connected to each other may be thicker than other portions due to the elastic reinforcement portion 757.

Here, even when the plurality of links 755 have a structure in which they are simply combined, elastic restoring force can be generated. However, due to the fact that the elastic reinforcement portion 757 is not made of metal, the elastic restoring force is of a size that is not sufficient to return the opening and closing head 710 to its original state when the discharge pressure of the pumping object applied to the opening and closing head 710 disappears. You can have power.

As in the second embodiment of the present disclosure, when the elastic reinforcement portion 757 is formed at a portion where two adjacent links among the plurality of linkages 755 are connected, the elastic restoring force between the plurality of linkages 755 can be increased. there is. In this case, the elastic restoring force may have a force sufficient to return the opening/closing head 710 to contact with the tapered portion 225a of the support piece 225 when the discharge pressure of the pumping object disappears.

On the other hand, any one of the plurality of connection rings 755 connected to the first ring 751 or the second ring 753 is also connected to the first ring 751 or the second ring 755 through the elastic reinforcement portion 757. It can be combined with the second ring (753). Through this, the elastic restoring force of the opening and closing unit 750 can be further strengthened.

At this time, when the first ring 751 and the second ring 753 are formed of a non-metallic material with elastic restoring force, the pressure applied to the opening and closing unit 750 is applied to the first ring 751 and the second ring 753. Some of it may be absorbed. Therefore, the components of the opening and closing unit 750 (e.g., the first ring 751, the second ring 753, and the plurality of connecting rings 755) are damaged or cracked due to excessive external pressure. You can prevent it from happening.

Meanwhile, referring to Figure 6a, the thickness (L1) and depth (H1) of the elastic reinforcement portion 757 are disclosed.

In the embodiment of the present disclosure, the thickness L1 of the elastic reinforcement portion 757 is the thickness L2 of any one connection ring 755b among the plurality of connection rings 755 and any one connection ring 755b. It may be formed to be equal to or thicker than the sum (L2+L3) of the thicknesses (L3) of the adjacent connecting rings (755c) that are connected.

When the thickness (L1) of the elastic reinforcement portion 757 is equal to the sum of the thicknesses (L2 + L3) between the above-described links (755b and 755c), when the plurality of links (755) are completely compressed, a plurality of The plate surfaces of the connecting rings 755 may contact each other and form a single cylindrical shape.

At this time, in the case where the elastic reinforcement portion 757 improves the elastic restoration force of the links and increases the rigidity at the connection portion, the thickness L1 of the elastic reinforcement portion 757 is adjusted to the above-described connector links 755b and 755c. It is implemented to be thicker than the sum of the thicknesses of the liver (L2+L3).

In this case, the connection area between the adjacent links 755b and 755c becomes thicker, so it is possible to further delay the time when the elastic restoring force is weakened or the connection area is damaged even after long-term use.

In addition, although not shown in the drawings, the thickness of the elastic reinforcement portion 757 formed between the first ring 751 and the connecting ring 755 is the thickness of the first ring 751 and the first ring 751. It may be formed to be equal to or thicker than the sum of the thicknesses of the connecting ring 755 connected to. And, although not shown in the drawing, the thickness of the elastic reinforcement portion 757 formed between the second ring 753 and the connecting ring 755 is the thickness of the second ring 753 and the connection with the second ring 753. It may be formed to be equal to or thicker than the sum of the thicknesses of the connecting rings 755.

In addition, the inner depth H1 of the elastic reinforcement portion 757 is determined from the tangent line between any one of the plurality of connections 755 (755c) and the elastic reinforcement portion 757. It may be formed to be equal to or deeper than the outer depth (H2) formed to the outer surface of .

When the inner depth H1 of the elastic reinforcement portion 757 is formed to be equal to or particularly deeper than the outer depth H2, the rigidity of the elastic reinforcement portion 757 can be further improved.

Each time the pumping object is discharged, the adjacent links undergo considerable compression and tension due to the discharge pressure of the pumping object. At this time, if the inner depth (H1) of the elastic reinforcement portion 757 is formed deeper than the outer depth (H2), the area where compression and tension are repeated is formed thicker, so that durability can be maintained even after considerable repetition.

In addition, the thicker depth in the inner part of the elastic reinforcement portion 757 ensures that the elastic restoring force is maintained even after long-term use. That is, since the connection portion between the adjacent links 755b and 755c is thicker, the elastic restoring force can be maintained for a long time.

In addition, although not shown in the drawings, the inner depth of the elastic reinforcement portion 757 formed between the first ring 751 and the connecting ring 755 is the connecting ring 755 connected to the first ring 751. It may be formed deeper than or equal to the outer depth formed from the tangent between the elastic reinforcement portion 757 and the outer surface of the elastic reinforcement portion 757. And, the inner depth of the elastic reinforcement portion 757 formed between the second ring 753 and the connecting ring 755 is the elastic strengthening portion 757 and the connecting ring 755 connected to the second ring 753. It may be formed deeper than or equal to the outer depth formed from the tangent between the liver to the outer surface of the elastic reinforcement portion 757.

Meanwhile, referring to FIG. 6A, the state before the opening and closing member 700 opens the nozzle passage 227 is disclosed.

And referring to Figure 6b, as the user presses the head body 210 with force F, the head body 210 descends inside the upper receiving part 311, and the operation of the pumping part 400 described above The pumping object moves from the stem passage 417 to the head passage 211, and the opening and closing member 700 opens the nozzle passage 227 by the discharge pressure of the pumping object moving to the head passage 211. You can check it.

Due to the discharge pressure of the pumping object, the opening/closing head 710 is pushed backward as shown by the arrow A0, and the opening/closing unit 750 is compressed.

The pumping object is pumped through the nozzle passage through the through hole 751a of the first ring 751, the through hole 755a of the connecting ring 755, and the through hole 753a of the second ring 753, as shown by arrow A1. After passing through (227), it is discharged to the outside.

Meanwhile, referring to FIG. 8, another form of the opening/closing unit 750 according to the second embodiment of the present disclosure is disclosed.

In another form, the opening and closing unit 750 may further include a ring deformation portion 758 and a ring cut portion 759.

Here, the ring deformation portion 758 and the ring cut portion 759 may perform the same function as the deformation portion 745 and the cut portion 747 of the first embodiment disclosed in FIG. 3B.

Specifically, the ring deformation portion 758 is disposed in the through hole 753a of the second ring 753, and can close the through hole 753a of the second ring 753. And at least one ring cut portion 759 may be formed on the ring deformation portion 758. In the embodiment of the present disclosure, four ring cut portions 759 are formed, but it is not necessarily limited thereto.

The ring deformation portion 758 is bent and deformed in an outward direction by the discharge pressure of the pumping object, and the pumping object is discharged to the outside into the space between them.

At this time, the ring deformation portion 758 spreads on both sides based on the ring cut portion 759 to form a space through which the pumping object can be discharged. That is, the through hole 753a of the second ring 753 is opened.

When the user subtracts the force (F) pressing the head body 210, the stem 410 and the head body 210 move upward due to the elastic restoring force of the pumping spring 450, so the discharge pressure of the pumping object weakens. In this case, the opening and closing member 700 is returned to its original position.

At this time, since the ring deformation portion 758 also does not receive discharge pressure, the shape that is bent outward and spread along the ring cut portion 759 is returned to its upright position, and the through hole 753a of the second ring 753 is closed. do.

Through this, it is possible to prevent the pumping object remaining in the nozzle passage 227 from leaking out. Additionally, by preventing the pumping object remaining in the nozzle passage 227 from being exposed to the air, it is possible to prevent or alleviate the problem of hardening due to evaporation of moisture, etc.

According to at least one of the above-described embodiments of the present disclosure, a) the nozzle can be opened and closed according to the discharge pressure of the pumped object, thereby preventing the pumped object from leaking excessively to the outside. b) In addition, by sealing the nozzle, the pumping object remaining inside the nozzle can be prevented or alleviated from hardening due to exposure to air. c) Additionally, there is an advantage in increasing the recyclability of the pump dispenser by providing an elastic body made of the same material or non-metallic material as the pump dispenser.

In the present disclosure, the pump dispenser is not limited to the configuration and method of some of the embodiments described above, but may be configured by selectively combining all or part of each embodiment so that various modifications can be made. It may be possible.
