Description

[Technical Field]

[0001] The present invention relates to a liquid dispensing device for dispensing liquid from a paper container containing liquid such as cosmetics or detergent. [Background technology]

[0002] A liquid removal device for removing liquid from a paper container containing liquid such as cosmetics or detergent includes a support member that has an outlet in the center of the top surface and a conical bottom with the center at the deepest point, and that stores and supports the bottom of the paper container containing the liquid; a lid member that fits from above around the outer periphery of the paper container supported by the support member to store the paper container inside, and whose tip can be hooked onto the support member; and a dispensing pump that is attached to the top surface of the lid member and inserts a suction tube into the paper container from the outlet of the paper container supported by the support member to suck in the liquid and discharge it to the outside; when the lid member is fitted around the outer periphery of the paper container from above, the suction tube of the dispensing pump is inserted into the outlet of the paper container, making it possible to minimize the amount of liquid remaining in the paper container after removal (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-1235303 Summary of the Invention [Problem to be solved by the invention]

[0004] The liquid take-out device described in Patent Document 1 is used by fitting a lid from above onto the outer periphery of a paper container for liquid, with the tip of the lid hooked onto a support that houses and supports the bottom of the paper container for liquid, so there is a problem in that paper containers for liquid that are taller than the height that can fit within the lid and support cannot be used. Also, the lid and support are made of a relatively rigid material, and if the material is synthetic resin, there are problems with the environment and disposal.

[0005] One possible solution to this problem would be to stop hooking the tip of the lid body to the support, shorten the vertical length of the lid body and support, and use a bowl-shaped liquid removal means attachment with a liquid removal means that fits snugly onto the upper outer periphery of the liquid paper container rather than the lid body, leaving a gap between the liquid removal means attachment and the support.However, if the liquid removal means attachment or support is shortened in order to address environmental issues and disposability, there is a risk that the liquid removal means attachment or support may easily come off the liquid paper container.

[0006] SUMMARY OF THE INVENTION An object of the present invention is to provide a liquid dispenser for a paper container for liquid that can be used for paper containers of liquid of different heights and is environmentally friendly and easy to dispose of. [Means for solving the problem]

[0007] In order to achieve the above object, the invention described in claim 1 is a liquid removal device for removing liquid from a paper container for liquid which has a flat top surface, flaps folded down from the top surface on the sides of the body, a gabled roof-shaped bottom with the center at its deepest point, and an outlet in the center of the top surface, the device comprising: a bowl-shaped liquid removal means attachment which fits around the upper outer periphery of the paper container for liquid and which has liquid removal means for removing liquid from the outlet of the paper container for liquid and discharging it to the outside; and a cylindrical bottom support which fits around the lower outer periphery of the paper container for liquid and supports the bottom. the height of the liquid removal means mounting body and the bottom support body is such that there is a gap between the liquid removal means mounting body and the bottom support body when the liquid removal means mounting body is fitted to the liquid paper container; The liquid take-out means attachment member is attached to the inner wall of the bowl, and when fitted to the top of the paper container for liquid, it climbs over the flap and is removably attached to the side edge of the flap. Has heightThe bottom support body is provided with a protrusion, and the inner surface of the cylindrical wall is provided with a protrusion that climbs over the side edge of the gable roof surface of the bottom when engaged with the lower part of the liquid paper container and detachably engages with the side edge of the gable roof surface, and a base that abuts against the gable roof surface after the protrusion has climbed over it and supports the bottom.

[0008] According to the invention of claim 1, the container comprises a bowl-shaped liquid removal means attachment that has a liquid removal means for discharging liquid to the outside from the outlet of the liquid paper container and fits onto the upper outer periphery of the liquid paper container, and a cylindrical bottom support that fits onto the lower outer periphery of the liquid paper container and supports the bottom, so that it can be used with liquid paper containers of different heights as long as they have the same cross-sectional shape.

[0009] Furthermore, the liquid removal means attachment is provided with a protrusion on the inner wall of the bowl that climbs over the flap when fitted to the top of the paper container for liquid and releasably hooks onto the side edge of the flap. Therefore, when the liquid removal means attachment tries to come out of the top of the paper container for liquid, the protrusion hooks onto the side edge of the flap to prevent it from coming out, so even if the height of the liquid removal means attachment is short, there is no risk of it easily coming out of the top of the paper container for liquid. Furthermore, the bottom support is provided with a front support on the inner wall of the cylinder. The bottom support is provided with a protrusion that climbs over the side edge of the gable roof surface of the bottom when engaged with the bottom of the liquid paper container and releasably hooks onto the side edge of the gable roof surface, and a base that abuts against the gable roof surface after the protrusion has climbed over it and supports the bottom.Therefore, when the bottom support tries to come out from the bottom of the liquid paper container, the protrusion catches on the side edge of the gable roof surface to prevent it from coming out, so there is no risk of the bottom support easily coming out from the bottom of the liquid paper container even if the height of the bottom support is short. This allows the liquid extraction means attachment body and the bottom support to be shorter, thereby reducing the amount of material used, and contributing to environmental issues and ease of disposal even though the materials used for the injection pump attachment body and the cylindrical support body are synthetic resin.

[0010] The invention described in claim 2 is the invention described in claim 1, The height of the protrusions provided on the inner surface of the bowl wall of the liquid take-out means mounting body is 0.4 mm to 1.2 mm.

[0011] According to the invention described in claim 2, The height of the protrusion provided on the inner surface of the bowl wall of the liquid removal means attachment body is 0.4 mm to 1.2 mm, so when the liquid removal means attachment body tries to come out from the top of the liquid paper container, the protrusion hooks onto the side edge of the flap, preventing it from coming out.

[0012] The invention described in claim 3 is 1 or 2. The liquid extraction means is a discharge pump having a suction pipe inserted into the outlet of the liquid paper container, and sucking liquid from the liquid paper container through the suction pipe and discharging it to the outside. It is characterized by:

[0013] According to the invention described in claim 3, By operating the dispensing pump, the liquid can be easily discharged to the outside from the outlet of the paper container for liquid. [Effects of the Invention]

[0014] The device for taking out liquid from a paper container for liquid according to the present invention can be used for paper containers for liquid of different heights, and is environmentally friendly and easy to dispose of. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0016] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a device for taking out liquid from a paper container for liquid according to the present invention will be described in detail below with reference to the drawings. 1 to 10 show an example of an embodiment of a device for extracting liquid from a paper container for liquid according to the present invention, in which FIG. 1 is a perspective view of the liquid extraction device of this example, FIG. 2 is a cross-sectional view of the liquid extraction device shown in FIG. 1, FIG. 3 is an exploded cross-sectional view of the liquid extraction device shown in FIG. 1, FIG. 4 is an enlarged cross-sectional view of the liquid extraction means attachment in the liquid extraction device shown in FIG. 1, FIG. 5 is a partially omitted bottom view of the liquid extraction means attachment shown in FIG. 4, FIG. 6 is an explanatory diagram showing the liquid extraction means attachment shown in FIG. 4 fitted to the upper outer periphery of a paper container for liquid, FIG. 7 is an enlarged cross-sectional view of the bottom support in the liquid extraction device for dispensing shown in FIG. 1, FIG. 8 is a bottom view of the bottom support shown in FIG. 7, FIG. 9 is an explanatory diagram showing the bottom support shown in FIG. 7 fitted to the lower outer periphery of a paper container for liquid, and FIG. 10 is an explanatory diagram showing an example of an embodiment in which a suction pipe is detachably attached to a dispensing pump provided on the liquid extraction means attachment shown in FIG. 1.

[0017] The liquid dispensing device 1 in this example is a device for pouring liquid from a paper container 100 for liquid, which has a flat top surface 101, flaps 103 folded from the top surface 101 on the sides of the body 102, a gable-shaped bottom 104 facing downward with the center as the deepest part, and a dispensing outlet 105 in the center of the top surface 101.

[0018] First, the paper container 100 for liquids used in this example will be described. The paper container 100 for liquids has a body 102 with a substantially square cross section, and a flat top surface 101, as described above, which is the shape seen on the top surface of a paper container known as a brick-type container. A sealing sheet 106 is provided on the back surface of the top surface 101 to close the outlet 105, and is designed to be ruptured by piercing the suction pipe of a dispensing pump, which will be described later. The sealing sheet 106 is not particularly limited in material, as long as it is impermeable and rupturable. Furthermore, as described above, the bottom 104 is formed in a downward-facing gable roof shape, which is the shape seen on the top surface of a paper container known as a gable-top type. In this example, the cross-sectional shape of the body 102 of the liquid paper container 100 is approximately square, but this is not limited to this and may be rectangular.

[0019] It is desirable to use the paper container for liquid 100 in the form of a paper container for refilling liquid contents previously filed by the applicant (Patent Publication No. 2017-43382), but this is not limited to this.

[0020] The liquid removal device 1 in this example comprises a bowl-shaped liquid removal means attachment 4 that fits onto the upper outer periphery of the paper container 100 for liquid and has a liquid removal means 15 that removes liquid from the removal outlet 105 of the paper container 100 for liquid and discharges it to the outside, and a cylindrical bottom support 5 that fits onto the lower outer periphery of the paper container 100 for liquid and supports the bottom 104.

[0021] The liquid extraction means attachment body 4 has a protrusion 7 on the inner surface of the bowl wall 6 that fits around the upper outer periphery of the liquid paper container 100, which climbs over the flap 103 when fitted with the upper part of the liquid paper container 100 and removably hooks onto the side edge 103a of the flap 103.

[0022] When the liquid extraction means attachment body 4 is fitted into the paper container 100 for liquid, the protrusion 7 elastically deforms the flap 103 while climbing over it, and hooks onto the side edge 103a of the flap 103, securing the liquid extraction means attachment body 4 so that it does not come off the paper container 100 for liquid; and when the liquid extraction means attachment body 4 is pulled up, the protrusion 7 elastically deforms the side edge 103a of the flap 103, climbing over the side edge 103a of the flap 103, and is desirably of a height and shape that makes it easy to release from the hook.

[0023] The height of the protrusions 7 varies depending on the thickness of the paper material forming the paper container for liquids 100, but for known paper containers for liquids such as cosmetics and detergents, it is preferably 0.4 to 1.2 mm, and more preferably 0.5 to 1.1 mm. Furthermore, it is preferable for the corners to be chamfered or curved. In this example, the protrusions 7 are provided on four surfaces of the bowl wall 6, but it is sufficient that they are provided on at least one surface, and even better, on two opposing surfaces.

[0024] In this example, the liquid extraction means 15 provided in the liquid extraction means attachment body 4 is a dispensing pump 3 that sucks liquid from the liquid paper container 100 and discharges it to the outside. The dispensing pump 3 is composed of a cylindrical cylinder portion 8, a dispensing nozzle 9 provided at the top of the cylindrical cylinder portion 8 and also serving as an operating part for a piston that fits slidably within the cylindrical cylinder portion 8, and a suction pipe 2 provided at the bottom of the cylindrical cylinder portion 8.

[0025] The dispensing pump 3 configured in this manner has a cylindrical cylinder portion 8 that penetrates and is fixed to the top surface portion 10 of the liquid extraction means mounting body 4, a dispensing nozzle 9 arranged on the upper side of the top surface portion 10, and a suction pipe 2 arranged on the lower side of the top surface portion 10, so that when the dispensing pump mounting body 4 is fitted onto the outer periphery of the liquid paper container 100 from above, the suction pipe 2 of the dispensing pump 3 is inserted into the extraction outlet 105 of the liquid paper container 100.

[0026] When the inner surface of the top surface 10 of the liquid extraction means attachment body 4 fitted onto the outer periphery of the paper container 100 abuts the top surface of the paper container 100, the tip of the suction pipe 2 of the dispensing pump 3 inserted from the outlet 105 of the paper container 100 is located at the deepest part of the gable-roof-shaped bottom 104 of the paper container 100. In this example, the suction pipe 2 is detachably attached to the dispensing pump 3 as shown in Figure 10. There are no particular limitations on the attachment and detachment means.

[0027] In this example, the liquid extraction means 15 is a pouring pump 3, but it is not limited to this and may be anything that can extract liquid to the outside from the outlet 105 of the liquid paper container 100.

[0028] The bottom support body 5, which fits onto the outer periphery of the lower part of the liquid paper container 100 and supports the bottom 104, has a protrusion 12 on the inner surface of the cylindrical wall 11 that, when fitted onto the lower part of the liquid paper container 100, climbs over the side edge of the gable roof surface 107 of the bottom 104 and enters the gap on the end wall 108 side, and detachably hooks onto the side edge 107a of the gable roof surface 107.

[0029] When the bottom support body 5 is fitted to the bottom of the paper container 100 for liquid, the protrusion 12 elastically deforms the side edge 107a of the gable roof surface 107, rides over it, and hooks onto the side edge 107a of the gable roof surface 107, securing the bottom support body 5 so that it does not come off the paper container 100 for liquid.It is also desirable that the protrusion 12 has a height and shape that allows it to elastically deform the side edge 107a of the gable roof surface 107 when the bottom support body 5 is pulled downward, ride over the side edge 107a, and easily come off the hook.

[0030] The height of the protrusions 12 varies depending on the thickness of the paper material forming the paper container for liquids 100, but in the case of known paper containers for liquids such as cosmetics and detergents, it is preferably 0.4 to 1.5 mm, more preferably 0.5 to 1.4 mm, and the corners are preferably chamfered or curved. In this example, the protrusions 12 are provided on four surfaces of the cylindrical wall 11, but it is sufficient that they are provided on at least one surface, and even better, they are provided on two opposing surfaces.

[0031] The bottom support body 5 also has a base 13 that abuts against the gable roof surface 107 after the protrusion 12 has climbed over the side edge 107a and supports the bottom 104 of the paper container 100 for liquid.

[0032] In this example, the base portion 13 is composed of four base pieces 13a that are arranged to protrude toward the center from the inner corners of the four corners of the cylindrical wall 11 of the bottom support body 5, and the upper surfaces 14 of the base pieces 13a form the abutment surfaces of the gable roof surface 107 after the protrusion portion 12 has passed over them.

[0033] The upper surface 14 of the base piece 13a is inclined downward toward the center, and the angle of inclination is the same as or larger than the angle of inclination of the gable roof surface 107 of the bottom 104. In this example, the angle of inclination of the upper surface 14 of the base piece 13a with respect to the horizontal direction is slightly larger than the angle of inclination of the gable roof surface 107.

[0034] In addition, the length from the upper surface 14 of the base piece 13a in the bottom support 5 to the lower end of the bottom support 5 is such that when the gable roof surface 107 of the bottom 104 of the liquid paper container 100 is abutted against and supported by the upper surface 14 of the base piece 13a, the tip seal portion 109 of the bottom 104 does not protrude from under the bottom support 5.

[0035] The liquid removal device 1 configured in this manner comprises a bowl-shaped liquid removal means attachment body 4 that fits onto the upper outer periphery of the liquid paper container 100 and has a liquid removal means 15 that discharges liquid to the outside from the removal outlet 105 of the liquid paper container 100, and a cylindrical bottom support body 5 that fits onto the lower outer periphery of the liquid paper container 100 and supports the bottom 104, so that it can be used with liquid paper containers 100 of different heights as long as they have the same cross-sectional shape.

[0036] Furthermore, the liquid removal means attachment body 4 has a protrusion 7 on the inner surface of the bowl wall that climbs over the flap 103 when engaged with the top of the paper container 100 for liquid and releasably hooks onto the side edge 103a of the flap 103. Therefore, when the liquid removal means attachment body 4 tries to come out from the top of the paper container 100 for liquid, the protrusion 7 hooks onto the side edge 103a of the flap 103, preventing it from coming out, so that even if the height of the liquid removal means attachment body 4 is short, there is no risk of it easily coming out from the top of the paper container 100 for liquid.

[0037] In addition, the bottom support body 5 is provided with a protrusion 12 on the inner surface of the cylindrical wall 11 that climbs over the side edge 107a of the gable roof surface 107 of the bottom 104 when engaged with the bottom of the paper container for liquid 100 and releasably hooks onto the side edge 107a of the gable roof surface 107, and a base 13 that abuts against the gable roof surface 107 after the protrusion 12 has climbed over it and supports the bottom 104.Therefore, when the bottom support body 5 tries to come out from the bottom of the paper container for liquid 100, the protrusion 12 catches on the side edge 107a of the gable roof surface 107 to prevent it from coming out, so there is no risk of the bottom support body 5 easily coming out from the bottom of the paper container for liquid 100 even if the height direction of the bottom support body 5 is short.

[0038] This allows the liquid removal means mounting body 4 and bottom support body 5 to be shorter, thereby reducing the amount of material used, and contributing to environmental issues and ease of disposal even though the liquid removal means mounting body 4 and bottom support body 5 are made of synthetic resin.

[0039] In addition, the bottom support body 5 abuts against the gable roof surface 107 after the protrusion 12 has passed over it, and is provided with a base portion 13 that supports the bottom portion 104.Therefore, by fitting the bottom support body 5 to the bottom of the liquid paper container 100, the gable roof surface 103 of the bottom portion 104 of the liquid paper container 100 abuts against the base portion 13, and the bottom portion 104 of the liquid paper container 100 can be supported in an upright position.
