Description

Dispenser and fluid container including the same

[0001] The present invention relates to a dispenser and a fluid container including the same, and more specifically, to a dispenser with excellent water resistance and a fluid container including the same.

[0002] Containers containing fluid household products widely used in daily life are equipped with small manual pumps. Therefore, by simply pressing the pump, a constant amount of fluid is dispensed, making it easy to use. Such pump devices are also called dispensers.

[0003] When the pump is pressed, the contents inside the pump's chamber can be discharged out through the nozzle. When the pressing force is released, the pump returns to its original upward position due to the elastic force of a spring installed between the container and the pump, causing the contents inside the container to be sucked into the pump's chamber.

[0004] Dispensers of this type are also widely used in shampoo containers to conveniently dispense a certain amount of shampoo solution contained inside the container. In the past, caps covered with ordinary lids and having a discharge opening for shampoo solution were used, but this caused inconveniences such as the need to pressurize the shampoo container to use it. Today, however, they are installed and used in most shampoo containers due to the structural advantages of convenient dispensing of shampoo solution and preventing waste by suppressing excessive dispensing.

[0005] Registered Patent No. 10-1366696 discloses a pump device for a shampoo container having an air chamber equipped with a piston having a double sealing structure so that the liquid inside the shampoo container does not leak to the outside, a return spring installed externally so as not to come into contact with the liquid, and a nozzle head equipped with a press-proof pin so that the nozzle head is not pressed during transport or movement.

[0013] It includes a nozzle head connected to the hollow shaft and applying pressure to the hollow shaft, and the nozzle head can be lowered and inserted and fastened between the cover portion and the through hole member.

[0014] The above-mentioned hollow shaft includes a housing that forms a space for vertical reciprocating motion, and the housing may have a negative pressure hole formed on the side for air inflow.

[0015] The dispenser includes a piston that rises and falls by the vertical reciprocating motion of the hollow shaft, and the hollow shaft may include a sub-shaft that penetrates the piston to form a fluid path.

[0016] The dispenser above includes a piston that rises and falls by the vertical reciprocating motion of the hollow shaft, and the piston may include a first groove and a second groove formed along the circumferential direction.

[0017] The above-mentioned hollow shaft includes a housing that forms a space for vertical reciprocating motion, and the above-mentioned chaflat includes a main member inserted into the inner side of the housing, and when the piston rises, one end of the main member may be positioned in the second groove of the piston.

[0018] The above hollow shaft may include a piston pressing portion located in the first groove of the piston when descending.

[0019] One embodiment of the present invention provides a fluid container comprising: a dispenser according to one embodiment of the present invention; and a container body on which the dispenser is mounted.

[0020] The above container body may contain shampoo, conditioner, body wash, detergent, or cleanser.

[0021] A dispenser according to one embodiment of the present invention may have excellent water resistance.

[0022] According to one embodiment of the present invention, contaminants such as water entering through the tolerance between the chaflat and the hollow shaft can be prevented from penetrating into the housing.

[0023] In addition, according to one embodiment of the present invention, the airtightness of the chaflat and the hollow shaft can be improved, and accordingly, contaminants such as water can be prevented from entering.

[0024] According to one embodiment of the present invention, the airtightness of the chaflat and the housing can be improved, and accordingly, contaminants (W) such as water or fluids can be prevented from entering.

[0043] The terms used in this invention are for the description of specific embodiments and are not intended to limit the claims. As used in the description of embodiments and the appended claims, the singular form is intended to include the plural form unless the context clearly indicates otherwise.

[0044] FIG. 1 is a perspective view schematically showing a fluid container according to one embodiment of the present invention, and FIG. 2 is a cross-sectional view schematically showing a state in which a dispenser according to one embodiment of the present invention is attached to a fluid container.

[0045] Referring to FIGS. 1 and 2, a fluid container according to one embodiment of the present invention may include a container body (200) having an opening and containing a fluid inside; and a dispenser (100) connected to the opening. A dispenser (100) according to one embodiment of the present invention may be mounted on the container body (200) of the fluid container according to one embodiment of the present invention.

[0046] The fluid that can be contained in the above fluid container is not particularly limited. It may be, for example, a fluid such as shampoo, conditioner, body wash, detergent, cleanser, etc.

[0047] The above-mentioned container body (200) is not particularly limited as long as it is in a shape capable of accommodating fluid. Although not limited thereto, it may be, for example, cylindrical, polygonal, etc. In addition, the shape of the opening formed in the container body (200) is not particularly limited and may be, for example, cylindrical, polygonal, etc.

[0048] In one embodiment, the container body (200) may be formed of a synthetic resin. Although not limited thereto, it may be formed of, for example, polypropylene, polyethylene, low-density polyethylene, etc.

[0049] According to one embodiment of the present invention, the dispenser (100) may include a cap (160) that is fastened to an opening of the container body. The cap (160) may have a shape corresponding to the opening so that it can be fastened to an opening formed in the container body (200). Although not limited thereto, the cap (160) and the container body (200) may be fastened by a screw connection. Although not limited thereto, for example, a screw groove may be formed on the inner surface of the cap (160) and a screw thread may be formed on the opening of the container body so that the cap (160) and the container body (200) may be fastened together.

[0050] In one embodiment, the cap (160) may have a hole formed therein into which a housing (140) can be inserted, and the housing (140) may be inserted into the inner surface of the cap (160). The housing may be mounted in the opening of the container body by means of the cap (160).

[0051] In one embodiment, a gasket (161) may be placed on the surface where the opening of the housing (140) and the container body (200) come into contact, thereby ensuring airtightness.

[0052] Hereinafter, a dispenser (100) according to one embodiment of the present invention will be described.

[0053] FIG. 3 is a cross-sectional view schematically showing a part of a dispenser according to one embodiment of the present invention. FIG. 4 is a cross-sectional view schematically showing a chaflat according to one embodiment of the present invention, and FIG. 5 is a perspective view schematically showing a chaflat according to one embodiment of the present invention. FIG. 6 is a cross-sectional view schematically showing a hollow shaft and a sub-shaft according to one embodiment of the present invention.

[0054] A dispenser (100) according to one embodiment of the present invention comprises: a hollow shaft (120) that discharges fluid by vertical reciprocating motion; and a chaplet (130) that includes a through hole member that forms a through hole into which the hollow shaft is inserted. The hollow shaft (120) may include a support rib (120A) that extends from the side toward the outer upper side to a predetermined height so as to surround and accommodate one end (132) of the through hole member to a predetermined height.

[0055] The above hollow shaft (120) is supported by a chaflat (130) and can perform vertical reciprocating motion.

[0056] According to one embodiment of the present invention, the dispenser (100) may include a housing (140) that forms a space in which the hollow shaft moves vertically back and forth.

[0057] Additionally, in one embodiment, a nozzle head (110) may be connected to the upper part of the hollow shaft (120), and when a predetermined pressure is applied to the nozzle head (110), the hollow shaft (120) may reciprocate vertically inside the housing (140).

[0058] When the dispenser (100) is connected to the opening of the container body, the housing (140) can be located inside the container body (200). The housing (140) is formed downward within the container body (200), and an inlet that is opened and closed by a ball (B) can be formed at its lower end.

[0059] In one embodiment, a tube (190) may be connected to the lower portion of the housing (140), and fluid in the container body (200) may flow into the housing (140) through the tube (190).

[0060] The hollow shaft (120) can reciprocate vertically inside the housing (140). A nozzle head (110) may be connected to the upper part of the hollow shaft (120), and when a predetermined pressure is applied to the nozzle head (110), the hollow shaft (120) can reciprocate vertically inside the housing (140).

[0061] In one embodiment, a piston (180) may be connected to the hollow shaft (120), and the piston (180) may also perform vertical reciprocating motion within the housing (140) by means of the vertical reciprocating motion of the hollow shaft (120). The outer surface of the piston (180) may be formed to be in close contact with the inner surface of the housing (140), and the interior of the housing (140) may be pressurized or depressurized by the vertical reciprocating motion of the piston (180).

[0062] In one embodiment, the piston (180) may have a groove formed along the circumferential direction. The groove allows the piston to move up and down smoothly within the housing. Due to the groove, the piston may contract towards the center or expand towards the outer surface when moving up and down.

[0063] A chamber (170) may be formed in the lower part of the piston (180), and the chamber (170) can be understood as a space that is pressurized or depressurized into the internal space of the housing.

[0064] In one embodiment, an elastic member (150) may be connected to the lower end of the piston (180). The elastic member (150) is not limited thereto, but may be, for example, a spring. The elastic member (150) serves to restore the hollow shaft (120) and the piston (180) to their original position when the pressure applied to the nozzle head (110) is removed after they have descended due to a predetermined pressure.

[0065] In one embodiment, a negative pressure hole (P) may be formed on the side of the housing (140). When fluid inside the container body (200) is discharged to the outside during the compression process by the hollow shaft (120) and the piston (180), external air may be introduced through the negative pressure hole (P) to fill the space inside the container body (200) corresponding to the amount of fluid discharged. If the inflow of external air into the container body (200) is not smooth, the container body (200) may contract or the fluid inside the container body (200) may flow back. However, according to one embodiment of the present invention, air can be smoothly introduced through the negative pressure hole (P) formed in the housing (140), thereby preventing such phenomena.

[0066] In one embodiment, the chaflat (130) may serve to support the hollow shaft (120) to move vertically back and forth inside the container. The chaflat (130) may be inserted into the upper inner side of the housing (140), and a through hole (H) into which the hollow shaft (120) is inserted may be formed.

[0067] The above chaflat (130) may refer to a chaflat-shaped structure.

[0068] Referring to FIGS. 4 and 5, the chaflat (130) may include a through-hole member (132) that forms a through-hole (H) into which the hollow shaft is inserted. The through-hole member (132) may wrap around the outer surface of the hollow shaft (120) and support the vertical reciprocating motion of the hollow shaft.

[0069] Additionally, the above-mentioned chaflat may include a main member (131) inserted into the inner side of the housing (140). In one embodiment, the main member (131) may be formed at a predetermined distance from the through-hole member (132) and may be formed along the circumferential direction of the through-hole member.

[0070] Additionally, the above-mentioned chaflat (130) may include a cover portion (133) that is fastened to the housing (140). In one embodiment, the cover portion (133) may be formed to extend outwardly downward from the upper end of the main member (131) to cover the upper end of the housing. The chaflat (130) may be fixed to the housing (140) by the cover portion (133). Although not limited thereto, screw threads may be formed on the upper outer surface of the housing (140), and screw grooves may be formed on the inner surface of the cover portion (133) so that the housing (140) and the chaflat (130) can be fastened together.

[0071] In one embodiment, the nozzle head (110) can be lowered and inserted and fastened between the cover portion (133) and the through hole member (132).

[0072] In one embodiment, the chaflat cover portion (133) may be formed at a predetermined distance from the chaflat through-hole member (132), and a nozzle head (110) may be inserted and fastened at the predetermined distance. When the nozzle head (110) is inserted and fastened to the chaflat (130) after the hollow shaft (120) is lowered, the vertical reciprocating motion of the hollow shaft (120) may be restricted. Accordingly, fluid discharge to the outside in unintended situations may be prevented.

[0073] FIG. 6 is a cross-sectional view schematically showing a hollow shaft (120) and a sub-shaft (121) according to one embodiment of the present invention, and FIG. 7 is a drawing for explaining the combined structure of a chaflat (130) and a hollow shaft (120).

[0074] Referring to FIGS. 6 and 7, a support rib (120A) may be formed on the lower part of the hollow shaft (120). The support rib (120A) may be formed to extend a predetermined height from the side of the hollow shaft (120) toward the outer upper side to surround and accommodate one end of the through-hole member (132) of the chaflat at a predetermined height.

[0075] In one embodiment, the inner surface of the chaflat through-hole member (132) may come into contact with the outer surface of the hollow shaft (120), and the lower end of the through-hole member (132) may be received in the support rib (120A).

[0076] The support rib (120A) may be formed on the lower side of the hollow shaft (120) as illustrated. Alternatively, the lower end of the hollow shaft (120) may be formed by extending outwardly upward.

[0077] The support rib (120A) may have a predetermined height to accommodate a predetermined length from the lower end of the through hole member (132). Although not limited thereto, for example, the height (T) of the support rib (120A) may be 0.5 to 1.5 mm. Specifically, it may be 0.8 to 1.3 mm or 1.0 to 1.3 mm. In addition, the width (W) of the support rib (120A) formed by extending outward from the side of the hollow shaft (120) may be 1.0 to 2.0 mm. In addition, the thickness (S) of the support rib (120A) may be 0.8 to 1.5 mm. If it falls outside the above range, it may be difficult to accommodate contaminants such as water.

[0078] FIG. 10 is a schematic diagram showing the state in which the hollow shaft (120) is lowered according to one embodiment.

[0079] In one embodiment, a piston pressing portion (120B) may be formed at the lower end of the hollow shaft (120). When the hollow shaft (120) descends and pushes the piston (180), the piston pressing portion (120B) formed at the lower end of the hollow shaft (120) may come into close contact with the piston (180). In one embodiment, the length (L1) of the piston pressing portion (120B) may be 0.5 to 1.5 mm.

[0080] In one embodiment, the piston (180) may have a groove formed along the circumferential direction, and the groove may include a first groove (182) and a second groove (183).

[0081] In one embodiment, when the piston (180) descends, the piston pressing portion (120B) may be positioned in the first groove (182) of the piston. The piston pressing portion (120B) may come into contact with the first groove (182) to maintain the descended state of the piston. Additionally, air compression can be effectively performed when the nozzle head (110) is pressed. The piston pressing portion (120B) of the hollow shaft (120) has a wide contact area with the piston (180), allowing air to be effectively extruded even if there is a tolerance between the hollow shaft (120) and the piston (180).

[0082] In one embodiment, the hollow shaft (120) may include a sub-shaft (121).

[0083] The above sub-shaft (121) has a hollow shape and can form a fluid flow path together with the hollow shaft (120). In one embodiment, the sub-shaft (121) can be positioned to pass through the piston (180) and can be connected to the chamber (170) to pass through the piston (180) to form a fluid path.

[0084] In one embodiment, the sub-shaft (121) may be inserted into the lower end of the hollow shaft (120). The outer surface of the sub-shaft (121) may come into contact with the inner surface of the hollow shaft.

[0085] In one embodiment, the through hole (H) of the chaflat (130) may come into contact with the outer surface of the hollow shaft (120). Specifically, the inner surface of the chaflat through hole member (132) may come into contact with the outer surface of the hollow shaft (120).

[0086] As illustrated in FIG. 4, in one embodiment, the chaflat (130) may include a contact projection (135) that protrudes inwardly toward the upper side of the chaflat. Specifically, the contact projection (135) may be formed on the upper part of the chaflat through-hole member (132), protrude inwardly toward the chaflat, and may be formed at a predetermined height. The chaflat through-hole member (132) may be more closely attached to the outer surface of the hollow shaft (120) by the contact projection (135). Although not limited thereto, the height (L) of the contact projection may be 0.5 to 1.5 mm. The height (L) of the contact projection may be understood as the height of the portion protruding inwardly. For example, it may be the length from the portion where the inward protrusion begins in the through-hole member (132) to the portion where the inward protrusion ends. In the case of FIG. 4, the upper end of the through hole member (132) can be understood as the part where the inner protrusion ends. The thickness of the through hole member (132) may be 0.3 to 0.8 mm. Within this range, airtightness between the chaflat through hole member (132) and the hollow shaft (120) can be ensured, thereby preventing the ingress of contaminants such as water.

[0087] In one embodiment, the main member (131) of the chaflat (130) is in contact with the upper inner surface of the housing.

[0088] FIGS. 5 and FIGS. 8 are perspective views schematically showing a chaflat (130) according to one embodiment of the present invention, and FIG. 9 is a drawing for explaining the combined structure of the chaflat (130) and the housing (140).

[0089] Referring to FIGS. 5 and 8, a pressure ring (138) may be formed along the outer surface of the main member (131) of the chaflat main member. Through the pressure ring (138), the chaflat main member (131) can come into closer contact with the inner surface of the housing.

[0090] In one embodiment, the pressure ring (138) may be in the form of a ring that is continuously formed along the outer surface of the main member (131). Alternatively, the pressure ring (138) may include an air passage (P1) for the inflow of air. In one embodiment, the pressure ring (138) may be in the form of a ring having an air passage (P1). The air passage (P1) may be in the form of a segment cut. In one embodiment, one or more segment cuts may be included. Although not limited thereto, for example, the segment cuts may be in the form of a continuous ring that is cut off, and are not particularly limited thereto. The segment cuts may be in the form of a groove such as a V, U, or 11, for example, but are not limited thereto.

[0091] Referring to FIG. 9, the chaflat (130) is inserted so as to be in contact with the inner surface of the housing. To this end, the outer diameter of the chaflat main member (131) may be formed to be similar or identical to the inner diameter of the housing. The pressure ring (138) formed on the main member (131) may be a structure that protrudes slightly from the main member and may not hinder the insertion of the chaflat main member (131) into the housing. The housing (140) has an open top, so that its diameter may be slightly expanded during the process of inserting the chaflat (130). After the insertion of the chaflat (130) is completed, the diameter of the housing (140) is restored to its original state, and the pressure ring (138) of the chaflat and the inner surface of the housing may be in close contact.

[0092] Accordingly, the above-mentioned pressure ring (138) can prevent fluid from penetrating into the housing (140). Further details regarding this will be described later.

[0093] The method of operation of a dispenser according to an embodiment of the present invention is as follows.

[0094] FIG. 10 is a schematic diagram showing the state in which the hollow shaft (120) of the dispenser is lowered.

[0095] Referring to FIG. 10, when a user presses the nozzle head (110), the hollow shaft (120) and sub-shaft (121) connected to the nozzle head (110) can descend. As the hollow shaft (120) and sub-shaft (121) descend, the piston (180) connected thereto is lowered, and accordingly, the elastic member (150) can be compressed.

[0096] When the piston (180) descends, the volume of the chamber (170), which is the space below the piston (180), decreases, and accordingly, the pressure of the chamber (170), which is the space inside the housing, increases. Accordingly, the fluid inside the chamber (170) can be discharged to the outside through the sub-shaft (121), the hollow shaft (120), and the nozzle head (110).

[0097] In one embodiment, when fluid inside the container body (200) is discharged to the outside during the compression process of the internal space of the housing as described above, external air may be introduced through the space between the chaflat (130) and the hollow shaft (120) to fill the space inside the container body (200) to the extent that the fluid was discharged. Also, referring to FIG. 10, air may be introduced through the negative pressure hole (P) of the housing (140).

[0098] However, fluid other than air may be introduced through the negative pressure hole (P) of the housing (140), and according to one embodiment of the present invention, the fluid introduced into the negative pressure hole (P) of the housing (140) can be blocked by the pressure ring (138) of the chaflat (130). This is because the main member (131) of the chaflat is in close contact with the inner surface of the housing (140) by the pressure ring (138).

[0099] In one embodiment, the pressure ring (138) may have an air passage (P1) for the inflow of air, and a minimum amount of air may be introduced through the air passage (P1).

[0100] In addition, in one embodiment, the piston pressing portion (120B) formed at the lower end of the hollow shaft (120) can be in close contact with the piston (180). Specifically, the piston pressing portion (120B) of the hollow shaft can be in close contact with the first groove portion (182) of the piston (180). Accordingly, air compression can be effectively performed when pressing the nozzle head (110). In addition, leakage of fluid moving through the interior of the hollow shaft (120) and the sub-shaft (121) can be prevented.

[0101] Afterward, when the pressure applied to the nozzle head (110) is removed, the hollow shaft (120) and the sub-shaft (121) rise due to the restoring force of the elastic member (150), and the piston (180) also rises along with the rise of the hollow shaft (120) and the sub-shaft (121). When the piston (180) rises, the volume of the internal space of the chamber (170) increases, and accordingly, the pressure in the internal space of the chamber (170) decreases, causing the ball (B) to rise and the inlet of the chamber (170) to open. At this time, the fluid inside the container body (200) moves back into the chamber (170) through the inlet. Referring to FIG. 3, when the hollow shaft (120) and the sub-shaft (121) are in a raised state, one end of the main member (131) of the chaflat can be inserted into the second groove (183) of the piston (180). When the piston (180) rises, one end of the main member (131) can act as a stopper. Additionally, the main member (131) and the piston (180) are in close contact, so that fluid can be prevented from flowing in through the negative pressure hole (P) of the housing (140).

[0102] FIG. 11 is a drawing for explaining the phenomenon that occurs during the operation process of a dispenser according to one embodiment of the present invention.

[0103] As described above, fluid is discharged to the outside by the vertical reciprocating motion of the hollow shaft (120) and the sub-shaft (121). At this time, external air may flow in and out of the space between the chaflat (130) and the hollow shaft (120) to fill the space inside the container body (200) to the extent that the fluid is discharged.

[0104] Generally, the above fluid container is used in an environment with a lot of water, and the discharged fluid is often used together with water. Therefore, during the vertical reciprocating motion of the hollow shaft (120), contaminants (W), such as water as well as air, may be introduced into the space between the chaflat (130) and the hollow shaft (120).

[0105] According to one embodiment of the present invention, the support rib (120A) formed on the hollow shaft (120) can prevent contaminants such as water from penetrating into the space between the chaflat (130) and the hollow shaft (120).

[0106] In addition, in one embodiment of the present invention, air may be introduced through the negative pressure hole (P) of the housing (140) during the reciprocating motion of the hollow shaft, and the fluid entering the negative pressure hole (P) of the housing (140) may be blocked by the pressure ring (138) of the chaflat (130). This is because the chaflat main member (131) is in close contact with the inner surface of the housing (140) by the pressure ring (138).

[0107] In addition, even when the dispenser (100) is repeatedly attached to or detached from the container body (200) in an environment with a lot of water, the pressure ring (138) of the above-mentioned chaplet (130) can prevent contaminants (W) such as water or fluid from penetrating into the housing (140).

[0108] FIG. 12 illustrates an example in which, unlike the present invention, support ribs are not formed on the hollow shaft (12). Referring to FIG. 12, contaminants (W), such as water, can flow into the housing without resistance due to the tolerance existing between the chaflat (13) and the hollow shaft (12). Accordingly, the fluid contained in the container body may be contaminated.

[0109] The present disclosure may be modified and implemented in various forms, and its scope of rights is not limited to the embodiments described above. Accordingly, if a modified embodiment includes the components of the claims of the present disclosure, it should be considered to fall within the scope of the present disclosure.
