Description

Technology Field

[0001] The present invention relates to a pump-type container, and more specifically, to a pump-type container that can smoothly perform a discharge operation by independently configuring an air inlet path for pumping action and a discharge path for contents, can prevent spoilage of contents by excluding the use of metal parts, and can reduce environmental pollution. Background Technology

[0002] Generally, a pump-type container is a container that discharges contents such as cosmetics, shampoo, and cleaning liquid contained in a container body by a pumping method, and consists of a container body and a pump installed in the container body.

[0003] For example, as a pump-type container, an extrusion pump for a liquid container disclosed in Korean Registered Utility Model No. 20-0384793 has been proposed.

[0004] The aforementioned Registered Utility Model No. 20-0384793 has a built-in metal spring for restoring the push button upward when it is lowered.

[0005] These conventional pump-type containers have problems such as contamination of the contents upon contact because the spring is made of metal, and environmental issues arising because the metal spring cannot be separated when the pump container is disposed of, making separate collection difficult.

[0006] In addition, conventional pump-type containers, such as Registered Utility Model No. 20-0384793, have the disadvantage of excessively high production costs due to high raw material and assembly costs, as they have many components and a complex structure.

[0007] In particular, conventional pump-type containers have a structure with a single flow path in which air introduced through a push button during pressurization pushes out the contents contained inside, and the contents are also discharged to the outside through the push button. Consequently, the discharge of contents is not smooth, and contents remaining at the bottom are not completely discharged, making it impossible to use efficiently. This results in significant waste and causes environmental pollution. Prior art literature

[0050] The pumping cap (4) is formed into a cap shape using a flexible material such as silicone resin or soft rubber resin so that an air chamber (a) is provided inside.

[0051] In this embodiment, the pumping plug (4) is composed of a pumping plug body (41) formed in a roughly hemispherical shape and a pumping plug fitting part (42) extending in a ring shape from the lower part of the pumping plug body, but is not limited thereto and can be formed in various shapes as long as it deforms and contracts when pressure is applied and can be restored to its original shape when pressure is released.

[0052] And the pumping plug (4) has a ring-shaped groove (44) formed so that the plug catch projection (244) of the pumping plug fastening part (24) is fitted and inserted into the inner circumference of the pumping plug fitting part (42).

[0054] Referring to FIGS. 4 to 6, the first valve part (5) is installed on the pumping plug (4) and is an opening / closing means for controlling air flow between the outside and the air chamber (a), which is the internal space of the pumping plug (4), and is equipped with a first opening / closing part (51) and a first blocking part (52).

[0055] The first opening / closing part (51) is a component that opens when suction force is applied to the air chamber (a) formed integrally with the pumping plug (4), and is formed of a material having elasticity such as silicone resin or soft rubber resin so that it can open while deforming when compressed air is introduced.

[0056] More specifically, the first opening / closing part (51) is provided with a first flow hole (511) formed in a structure in which the inner diameter decreases from the inlet of the pumping plug (4), a pair of first opening / closing wings (512) separated by a first cut hole (513) that protrudes downward and is formed vertically around the lower circumference of the first flow hole (511), and a first binding groove (514) that is recessed into the outer surface of the first opening / closing wings (512).

[0057] It is very important that the first flow hole (511) is formed with a structure in which the inner diameter decreases from the inlet, which is the direction of air inflow, toward the outlet, so that a pair of first opening / closing wings (512) spread apart and open when air flows in.

[0058] The first opening / closing wing (512) has a vertical section (512a) with a uniform outer diameter and an inclined section (512b) that extends from the lower part of the vertical section (512a) and has a gradually decreasing outer diameter. Here, the inclined section (512b) is formed so that its cross-section has an approximate right triangle shape.

[0059] The first blocking part (52) is a component coupled to the first opening / closing part (51) to perform the closing action of the first opening / closing part (51), and comprises a first binding ring (521) in the shape of a circular ring to be fitted around the circumference of the first opening / closing wing (512), a first locking projection (522) protruding from the inner surface of the first binding ring (521) to be inserted into the first binding groove (514), and a first blocking plate (523) in the shape of a roughly square plate formed across the center of the first binding ring (521) to be fitted into the first cut hole (513).

[0060] Referring to FIGS. 4, 5 and 7, the second valve part (6) is configured on the sealing plate (211) of the inner plug body (21) and is composed of a second opening / closing part (61) and a second blocking part (62) as a component that controls the air flow between the air chamber (a) and the contents receiving chamber (c) of the pumping plug (4).

[0061] The second opening / closing part (61) is installed in the opening / closing part installation hole (25) formed in the sealing plate (211) and is a component that opens when compressed air from the air chamber (a) flows in and closes when compressed air does not flow in. It is formed of a material having elasticity, such as silicone resin or soft rubber resin, so that it can open while deforming when compressed air flows in.

[0062] The second opening / closing part (61) is provided with a second opening / closing body (612) inserted into the opening / closing part installation hole (25), a second flow hole (611) formed with a structure in which the inner diameter is reduced from the second opening / closing body (612) which is the entrance, and a pair of second opening / closing wings (613) separated by a second cut hole (614) that extends downward from the second opening / closing body (612) and is formed vertically.

[0063] It is very important that the second flow hole (611) is formed with a structure in which the inner diameter decreases from the inlet, which is the direction of air inflow, toward the outlet, so that a pair of second opening / closing wings (613) spread apart and open when air flows in.

[0064] The second opening / closing body (612) is formed as a disc structure having a lower outer diameter larger than the upper outer diameter so that it is firmly fixed without being detached downward when compressed air flows into the second flow hole (611).

[0065] The second opening / closing wing (613) has a vertical section (613a) with the same outer diameter and an inclined section (613b) that extends from the lower part of the vertical section and has a gradually decreasing outer diameter. Here, the inclined section (613b) is formed so that its cross-section has an approximate right triangle shape.

[0066] The above opening / closing part installation hole (25) is formed with an upper narrow, lower wide structure having a narrow upper outer diameter and a large lower outer diameter, which corresponds to a shape into which the second opening / closing body (612) is inserted and secured.

[0067] The second blocking part (62) is a component formed by protruding from the bottom surface of the sealing plate (211) to be connected to the second opening / closing part (61) so as to perform a closing action of the second opening / closing part (61), and is composed of a second blocking plate (621) in the shape of a roughly square plate formed across the lower edge of the opening / closing part installation hole (25) so as to be fitted into the second cut hole (614).

[0068] Referring to FIGS. 4, 5 and 8, the third valve section (7) is configured in the contents discharge section (22) and the contents transfer pipe (3), and is a component that controls the external discharge of contents contained in the contents receiving chamber (c), and is composed of a third opening / closing section (71) and a third blocking section (72).

[0069] The third opening / closing part (71) is a component that is fitted and secured to the upper end of the contents transfer pipe (3) and opens to discharge contents when a discharge force is applied due to the inflow of compressed air into the contents receiving chamber (c). It is formed of a material having elasticity, such as silicone resin or soft rubber resin, so that it can open while deforming as contents flow through the contents transfer pipe (3).

[0070] The above third opening / closing part (71) is connected to the upper end of the contents transfer pipe (3) and has a third opening / closing body (712) formed with a third flow hole (711) having a structure in which the inner diameter decreases from the inlet, and a pair of third opening / closing wings (714) formed by a third cut hole (713) that extends upward and is formed vertically on one side of the third opening / closing body (712).

[0071] It is very important that the third flow hole (711) is formed with a structure in which the inner diameter decreases from the inlet, which is the direction of air inflow, toward the outlet, so that a pair of third opening / closing wings (714) spread apart and open when air flows in.

[0072] The third opening / closing wing (714) has a vertical section (714a) with a uniform outer diameter and an inclined section (714b) that extends from the lower part of the vertical section (714a) and has a gradually decreasing outer diameter.

[0074] The operation of a pump-type container according to one embodiment of the present invention is briefly explained below.

[0075] The attached drawings, FIGS. 9a and 9b, are drawings for explaining the operation of a pump-type container according to an embodiment of the present invention. FIGS. 9a (a) shows the operating state of the first to third valve sections when the pumping plug is in an expanded state (initial state before deformation), and FIGS. 9a (b) shows the operating state of the first valve section when the pumping plug is restored from a contracted state. FIGS. 9b (c) shows the operating state of the twelfth valve section during the pressurization operation of the pumping plug, and FIGS. 9b (d) shows the operating state of the third valve section during the pressurization operation of the pumping plug. Since FIGS. 9b (c) and (d) represent operating states that occur in the contracted state of the pumping plug, the pumping plug should be depicted in a contracted state, just like FIGS. 9a (b); however, to aid in understanding the operation of the second valve section and the third valve section, the pumping plug is depicted in a state before deformation.

[0076] Referring to FIGS. 9a and 9b, the assembly process of the pump-type container according to the present invention is briefly described as follows: a second opening / closing part (61) is assembled to the second blocking part (62) of the inner stopper (2), a first opening / closing part (52) is assembled to the first opening / closing part (51) formed in the pumping stopper (4), and then the pumping stopper (4) is pressed into the pumping stopper binding part (24) of the inner stopper (2) to bind it.

[0077] Then, a contents transfer pipe (3) with a suction guide member (8) attached to the pipe connection part (221) of the contents discharge part (22) of the inner stopper (2) is assembled. At this time, a third opening / closing part (71) is pressed into the upper part of the contents transfer pipe (3) so as to be connected to the third blocking part (72) formed inside the pipe connection part (221).

[0078] Afterwards, contents such as a cleaning agent are poured into the contents receiving chamber (C) of the container body (1), and the container connecting part (23) of the inner cap (2) is connected to the cap connecting part (13) of the container body (1), thereby completing the manufacturing of a product that can be used by a consumer.

[0079] To briefly explain the process of using the pump-type container product manufactured as described above, when the user presses the pumping plug (4) with their hand in the initial state as shown in part (a) of FIG. 9a, the air contained in the air chamber (a) is compressed and then pumped into the second flow hole (611) of the second opening / closing part (61). Since the second flow hole (611) is formed with a structure in which the inner diameter decreases from the inlet and the flow path narrows, as the air is compressed, it pushes out the contact area between the second blocking plate (621) and the inner surface of the second opening / closing wing (613), thereby deforming the second opening / closing wing (613), which is formed of a soft elastic material as shown in part (c) of FIG. 9b, so that it opens to the left and right while forming a gap.

[0080] Then, when the pumping plug (4) is compressed by hand and the compression operation is stopped, it returns to its original state due to the self-elastic restoring force of the pumping plug (4), as shown in part (b) of FIG. 9a. During this restoration process, negative pressure is applied inside the air chamber (a) of the pumping plug (4), so the suction force of external air is applied to the first flow hole (511) of the first opening / closing part (51). As a result, the suction force of the air, which is drawn into the first flow hole (511) formed with a structure in which the inner diameter of the external air decreases from the inlet, pushes out the contact area between the first blocking plate (523) and the inner surface of the first opening / closing wing (512), thereby deforming the first opening / closing wing (512), which is formed of a soft elastic material as shown in part (b) of FIG. 9a, causing it to spread to the left and right, so that the outside is drawn into and filled into the air chamber (a).

[0081] And as shown in part (a) of FIG. 9a, when the pumping plug (4) is restored to an expanded state and the user repeatedly performs the action of pressing the pumping plug (4) with their hand, the second opening / closing part (61) of the second valve part (6), which was maintained in a closed state by its own elastic restoring force, is repeatedly opened as shown in part (c) of FIG. 9b, thereby additionally pressurizing compressed air into the contents receiving chamber (c) to perform the pumping action.

[0082] As described above, when the second opening / closing wing (613) opens, compressed air is pumped into the contents receiving chamber (c) through the gap formed between it and the second blocking plate (621), thereby performing a pumping action, so that the contents contained flow from the lower part to the upper part of the contents transfer pipe (3).

[0083] In this way, when the contents are pumped into the third flow hole (711) of the third opening / closing part (71) by being pumped to the upper part of the contents transfer pipe (3), the inner diameter is formed to decrease from the inlet and the flow path is formed to narrow, so the transfer force pushes the contact area between the third blocking plate (721) and the inner surface of the third opening / closing wing (714), thereby deforming the third opening / closing wing (714) as shown in part (d) of FIG. 9b, so that it opens to the left and right while forming a gap.

[0084] As the third valve section (7) opens, the contents passing through the third opening / closing wing (714) are discharged to the outside through the discharge section (222), so the user can receive them with their hand and use them for the desired purpose.

[0085] Terms such as "include," "compose," or "have" as described above, unless specifically stated otherwise, mean that the relevant component may be inherent; therefore, they should be interpreted as allowing for the inclusion of additional components rather than excluding them. All terms, including technical or scientific terms, have the same meaning as generally understood by those skilled in the art to which the present invention pertains, unless otherwise defined. Commonly used terms, such as those defined in advance, should be interpreted in accordance with their meaning in the context of the relevant technology and should not be interpreted in an ideal or overly formal sense unless explicitly defined in the present invention.
