Description

[Technical field]

[0001] The present invention relates to a discharge mechanism and a discharge container. [Background technology]

[0002] There are known pump-type discharge mechanisms and discharge containers that discharge the contents contained in a container. Such discharge mechanisms and discharge containers are generally configured such that a piston is pushed down by a pressing body provided on a nozzle head or the like, and the contents are discharged to the outside at that time (for example, Patent Documents 1 and 2).

[0003] For example, Patent Document 1 discloses a pump-type discharge container which comprises a container body and a discharge pump body attached to the mouth of the container body, the discharge pump body comprising a cylindrical cylinder section which can communicate with the inside of the container body, a cylindrical piston section which is in sliding contact with the inner wall surface of the cylinder section and can move up and down to pressure-pump liquid upwards, a spring section which is interposed between the cylinder section and the piston section and urges the cylinder section downwards and the piston section upwards, and a nozzle head section which can communicate with the inside of the piston section and can move up and down in conjunction with the piston section, and which discharges liquid from the discharge port as a result of its downward movement.

[0004] It is disclosed that the discharge pump body is provided with a skirt-shaped base cap portion having a female thread formed on its inner circumferential surface, and the discharge pump body is secured to the container body by screwing the base cap portion into the mouth of the container body having a male thread formed on its outer circumferential surface.

[0005] Moreover, Patent Document 2 discloses a dispenser in which two containers are attached to a housing by screwing each of them. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2012-86186 A [Patent Document 2] WO2019 / 203064 Summary of the Invention [Problem to be solved by the invention]

[0007] In the configuration disclosed in Patent Document 1, when replacing a container after using the contents contained in the container, the user rotates the discharge pump body relative to the used container to remove it, and rotates it relative to a new container filled with the contents to attach it. However, in this case, it is necessary to repeatedly rotate the discharge pump body relative to the container to release the screw engagement between the discharge pump body and the container and screw the discharge pump body to the new container, which is time-consuming.

[0008] Even in the dispenser disclosed in Patent Document 2, when the contents of the two containers become low, it is necessary to unscrew and remove each container, and then re-screw and re-attach the container that is filled with the contents.

[0009] In view of the above, an object of one aspect of the present invention is to provide a discharge mechanism that allows a container to be easily attached and detached. [Means for solving the problem]

[0013] Hereinafter, the embodiment of the present invention will be described with reference to the drawings, but the present invention is not limited to the embodiment described in this specification. In the following description, the X direction, Y direction, and Z direction are perpendicular to each other, the X direction and the Y direction are parallel to the bottom surface of the container, and the Z direction is the height direction of the container. In this specification, the lower side means the lower side in the Z direction, and the upper side means the upper side in the Z direction.

[0014] First Embodiment A discharge mechanism 70 and a discharge container 100 according to a first embodiment of the present invention will be described. Fig. 1 is a side view of the discharge container 100 according to the first embodiment, and Fig. 2 is a top view of the discharge container 100 according to the first embodiment. Fig. 3 is an exploded perspective view of the discharge container 100 according to the first embodiment. Fig. 4 is a cross-sectional view taken along line II in Fig. 2, and Fig. 5 is a cross-sectional view taken along line II-II in Fig. 4.

[0015] As shown in Figs. 1 to 4, the discharge container 100 includes a discharge mechanism 70 and a container 30, and is configured to discharge the contents contained in the container 30 to the outside by a pump. The discharge mechanism 70 includes a discharge part 10 that discharges the contents in the container 30, a fitting part 20 into which the opening 31 of the container 30 can be fitted, and a rotating body 40 that is rotatably engaged with the discharge part 10 and the fitting part 20. The container 30 can be attached and detached to the discharge container 100 and the discharge mechanism 70 by rotating the rotating body 40. The configuration of the rotating body 40 will be described in detail later.

[0016] The contents discharged by the discharge container 100 according to the present embodiment are not limited as long as they exhibit fluidity at least when discharged and can be pushed out from the discharge port 12 of the discharge container 100 to the outside of the discharge container 100. The contents may be liquid, for example, a liquid of a pure substance or a liquid mixture. Furthermore, the contents may be, for example, a solution, and a dispersion such as an emulsion or a suspension, and may be in a state called a gel, a slurry, a paste, a cream, or the like. The contents may contain a powder, or may be mainly composed of a powder, or may be substantially composed of a powder, or may be composed of a powder, as long as it can be discharged from the discharge port 12. The contents may be a mixture of the above contents and a gas such as nitrogen, a rare gas, or air, and be contained in the container 30 in a foam state. The contents may be a paste or cream state having a viscosity similar to or higher than that of water.

[0017] Specifically, for example, the products may be skin care products or basic cosmetics such as lotion, milky lotion, face cream, serum, facial cleanser, cleansing agent, etc.; makeup cosmetics such as foundation, makeup base, concealer, liquid eye shadow, liquid blush, liquid lip product, etc.; personal care products (daily hygiene products) such as sunscreen, hand soap, body soap, hair shampoo, hair dye, styling agent, hand cream, body cream, body lotion, etc.; fragrance products, etc.

[0018] As shown in Figs. 3 and 4, the discharge part 10 includes a dispenser 14 for discharging the contents contained in the container 30 to the outside, a stem 141 which is an operating element in the dispenser 14, a pressing part 11 for pressing the stem 141, a discharge port 12 for discharging the contents, and a plug 13 for connecting the pressing part 11 and the dispenser 14. The dispenser 14 and the pressing part 11 are integrally assembled via the plug 13. When the discharge part 10 is operated, the contents are sucked up from the tip of the dispenser 14 and discharged from the discharge port 12. Specifically, by pressing the pressing part 11, the contents sucked into the dispenser 14 are discharged from the discharge port 12, and when the pressing is released, the spring force causes the discharge part 10 to return to the state before pressing. At this time, the inside of the dispenser 14 becomes negative pressure, so the contents in the container 30 are sucked into the dispenser 14.

[0019] The dispenser 14 has a suction pipe 142 to be inserted into the container 30, and a flange 143 is formed at the upper end of the suction pipe 142, extending outward from the suction pipe 142 (in a direction perpendicular to the Z direction). The outer diameter of the flange 143 is larger than the outer diameter of the opening 31 of the container 30. A ring-shaped packing 15 may be provided on the lower surface of the flange 143. The upper end of the opening 31 of the container 30 abuts against the flange 143 or the packing 15, thereby fixing the container 30 to the discharge part 10 in a liquid-tight manner.

[0020] The pump type of the discharge portion 10 is not limited to the one shown in the figure, and may be of a known configuration. The pressing action of the operating element (stem 141) may also be electrically performed.

[0021] The fitting portion 20 includes a chuck (fixture) 21 that can move between a position for holding the opening 31 of the container 30 and a position for releasing the holding, and a support member 22 that supports the chuck 21. In the illustrated embodiment, the chuck 21 includes three chuck pieces 21-1, 21-2, and 21-3 having an arc shape, and the chuck pieces 21-1, 21-2, and 21-3 are supported by the support member 22 so as to surround the opening 31 of the container 30. In this embodiment, the number of chuck pieces is three, but the number can be any number. The chuck 21 (chuck pieces 21-1, 21-2, and 21-3) each have a protrusion 211 (211-1, 211-2, and 211-3) on the upper surface (upper side in the Z direction). 4, the lower surface (lower side in the Z direction) of the chuck 21 has an inclined portion 213 inclined with respect to the XY plane so that the end portion on the side of the rotation center axis 41 of the rotating body 40 (inner side in the radial direction) is higher than the outer side end portion in the radial direction. Furthermore, the chuck 21 has a recess 212 on the surface facing the outer peripheral surface of the opening 31 of the container 30 (between the upper surface and the lower surface of the container 30). This recess 212 holds the outer peripheral surface of the opening 31 of the container 30, which will be described later.

[0022] The support member 22 has a cylindrical shape as a whole, and has a wall surface 222 extending radially inward from a cylindrical inner peripheral surface 221. As shown in FIG. 4, the wall surface 222 has a guide surface 223 formed thereon, which is inclined with respect to the XY plane (a surface perpendicular to the rotation central axis 41 of the rotating body 40) such that the end portion on the rotation central axis 41 side (radially inner) is higher than the end portion on the radially outer side. The support member 22 is capable of supporting the chuck 21 with the inner peripheral surface 221 and the guide surface 223. In addition, the inclined portion 213 of the chuck 21 is capable of sliding on the guide surface 223. The support member 22 has a ring-shaped convex portion 224 around the entire circumference on the inner peripheral surface on the lower end side. The convex portion 224 is capable of engaging with a second convex portion 33 of the container 30 described later. The lower surface side of the wall surface 222 of the support member 22 can be shaped to match the shape of the shoulder portion 34 of the container 30, thereby improving the appearance of the entire discharge container 100. However, the lower surface side of the wall surface 222 of the support member 22 may be shaped differently from the shape of the shoulder portion 34 of the container 30. In this embodiment, the support member 22 is detachably engaged with the plug 13.

[0023] The container 30 is a bottomed tubular shape having an opening 31. In this embodiment, the shape of the container 30 is a square tube, but is not limited thereto, and may be a cylinder or other shape. In other words, the cross-sectional shape of the container 30 perpendicular to the rotation center axis 41 of the rotating body 40 may be a circle, a polygon, or an ellipse. The container 30 has a ring-shaped first convex portion 32 formed on the outer circumferential surface of the opening 31, and a ring-shaped second convex portion 33 formed below the first convex portion 32. The first convex portion 32 engages with the recessed portion 212 of the chuck 21 to bring the upper end of the opening 31 of the container 30 into liquid-tight contact with the flange portion 143, so that the container 30 is held (fixed) by the chuck 21 and attached to the discharge portion 10. In addition, the second convex portion 33 engages with the convex portion 224 of the support member 22, so that the container 30 is engaged (temporarily attached) to the support member 22. In the present embodiment, the first convex portion 32 and the second convex portion 33 are shaped like a ring, but the shape is not limited thereto, and may be, for example, a plurality of arc-shaped convex portions that are intermittent. The above-mentioned attachment and temporary attachment will be described in detail later.

[0024] The rotating body 40 has a cylindrical shape, and the upper side of the inner peripheral surface 42 is rotatably held by the outer peripheral surface of the plug 13. In this embodiment, the rotating body 40 and the plug 13 are detachably engaged with each other by a locking member such as a groove and a protrusion (not shown). As shown in Figs. 4 and 5, the inner peripheral surface 42 has a rib 43 protruding radially inward from the center to the lower side. Three ribs 43 (43-1, 43-2, 43-3) are provided at positions facing the chuck pieces 21-1, 21-2, and 21-3. In this embodiment, the number of ribs 43 is three, but the number of ribs 43 may be any number as long as it is the same as the number of the chuck pieces 21-1, 21-2, and 21-3. On the surface (lower surface) of the rib 43 facing the chuck 21, elongated grooves 44 (44-1, 44-2, 44-3) are formed along the circumferential direction, as shown in Fig. 5. As shown in Fig. 5, the groove 44 is inclined from the outside to the inside in the circumferential direction or has a partial spiral shape in plan view. A protrusion 211 provided on the upper side surface of the chuck 21 engages with the groove 44, and the protrusion 211 moves along the groove 44 as the rotor 40 rotates. In other words, the groove 44 and the protrusion 211 form a cam mechanism. In the present embodiment, an example has been shown in which the protrusion 211 of the chuck 21 and the groove 44 of the rib 43 form a cam mechanism, but a protrusion may be provided on the rib 43, a groove may be formed in the chuck 21, and the protrusion of the rib 43 and the groove of the chuck 21 may form a cam mechanism.

[0025] The lower side of the inner peripheral surface 42 of the rotor 40 is rotatably held relative to the outer peripheral surface of the support member 22. With this configuration, the rotor 40 is rotatably held by the outer peripheral surface of the plug 13 and the outer peripheral surface of the support member 22, allowing smooth rotation. Note that the outer peripheral surface of the rotor 40 may be provided with grooves (flat knurled shape) parallel to the Z direction as an anti-slip feature. The anti-slip feature may also be a twill knurled shape.

[0026] Then, by rotating the rotating body 40 while the opening 31 of the container 30 is inserted into the fitting portion 20, the fitting portion 20 fits into the opening 31 and holds the container 30. Also, by rotating the rotating body in the opposite direction, the container 30 can be released from the holding state. As a result, when the container 30 becomes empty or the contents in the container 30 become low, the container 30 can be replaced with a new container 30 filled with the contents. Then, the discharge mechanism 70 can be continued to be used, and the environmental load can be reduced. Also, when the container 30 becomes empty or the contents in the container 30 become low, the container 30 can be removed from the discharge mechanism 70, filled with the contents, and then attached to the discharge mechanism 70 again.

[0027] Next, attachment and detachment of the container 30 will be described with reference to Figs. 6 to 12. Fig. 6 is a cross-sectional view taken along line II in Fig. 2, showing a state before the container 30 is attached. Fig. 7 is a cross-sectional view taken along line II in Fig. 2, showing a state in which the container 30 has been temporarily attached. Fig. 8 is an enlarged view of part A in Fig. 7, and Fig. 9 is a cross-sectional view taken along line III-III in Fig. 7. Fig. 10 is a cross-sectional view taken along line II in Fig. 2, showing a state in which the container 30 has been attached. Fig. 11 is an enlarged view of part B in Fig. 10, and Fig. 11 is a cross-sectional view taken along line IV-IV in Fig. 10.

[0028] As shown in FIG. 6, before the container 30 is attached, the chuck 21 is held in contact with the inner peripheral surface 221 and the guide surface 223 of the support member 22. When the opening 31 of the container 30 is inserted into the fitting portion 20, the second convex portion 33 of the container 30 first climbs over the convex portion 224 formed on the inner peripheral surface of the lower end portion of the support member 22, as shown in FIG. 7 and FIG. 8, and the container 30 is locked to the support member 22. This state is called temporary attachment. In the temporary attachment state, as shown in FIG. 8 and FIG. 9, the first convex portion 32 formed on the outer peripheral surface of the opening 31 of the container 30 and the concave portion 212 of the chuck 21 are separated. In addition, the upper end of the opening 31 of the container 30 is separated from the packing 15. In other words, the container 30 is temporarily fixed by the convex portion 224 of the support member 22. This makes it possible to prevent the container 30 from falling (separating) from the discharge mechanism 70, even if the container 30 does not need to be continuously held by hands or the like until the container 30 is fixed by the chuck 21.

[0029] In this state, when the rotating body 40 is rotated by a predetermined angle, clockwise in the case of FIG. 5, the protrusion 211 engaged with the groove portion 44 moves radially inward. Then, as shown in FIG. 10 and FIG. 11, the chuck 21 moves in a direction approaching the rotation center axis 41 by the above-mentioned cam mechanism in conjunction with the rotation of the rotating body 40, and rises (moves upward) along the guide surface 223 of the support member 22. By moving the chuck 21 obliquely upward in this manner, the recess 212 of the chuck 21 and the first protrusion 32 of the container 30 are engaged. In this state, the state in which the second protrusion 33 of the container 30 is engaged on the protrusion 224 formed on the inner peripheral surface of the lower end portion of the support member 22, which is a temporary attachment state, is released. As shown in FIG. 11 and FIG. 12, the second protrusion 33 on the outer peripheral surface of the opening 31 of the container 30 and the recess 212 of the chuck 21 are in close contact with each other. As a result, the container 30 is held by the chuck 21 and completely fixed to the discharge mechanism 70. In addition, the upper end of the opening 31 of the container 30 abuts against the packing 15. As a result, the container 30 is attached to the discharge mechanism 70 in a liquid-tight manner.

[0030] When removing the container 30, the rotating body 40 is rotated in the opposite direction to that during the above-mentioned mounting (counterclockwise in the case of FIG. 5), so that the chuck 21 moves in a direction away from the rotation center axis 41 and descends (moves downward) along the guide surface 223 of the support member 22. In this way, the chuck 21 moves in an obliquely downward direction, and the engagement between the recess 212 of the chuck 21 and the first protrusion 32 of the container 30 is released, resulting in the same state as the above-mentioned temporary mounting, in which the container 30 is temporarily fixed by the protrusion 224 of the support member 22. In this way, even if the mounting of the container 30 is released, the container 30 does not fall from the discharge mechanism 70, so that it is possible to eliminate the possibility of the contents remaining in the container 30 being scattered due to an inadvertent drop of the container 30. Then, by applying a downward force to the container 30 while holding it in the hand, or by applying an upward force to the discharge mechanism 70, the engagement between the second convex portion 33 of the container 30 and the convex portion 224 of the support member is released, allowing the container 30 to be safely and reliably removed from the discharge mechanism 70.

[0031] The rotation angle of the rotating body 40 is preferably 15 to 110 degrees. If it exceeds 110 degrees, it may be necessary to remove the hand from the container 30 and hold it again. If it is less than 15 degrees, it is difficult to adjust the rotation because the attachment and detachment are performed by a slight wrist rotation. In terms of the normal wrist rotation in daily life, 60 to 90 degrees is more preferable. This allows the user to easily attach and detach the container 30 with a small amount of operation compared to a discharge container that is attached and detached by a general screw type. Thus, according to this embodiment, the container 30 can be reliably attached to the discharge mechanism 70 by rotating the rotating body 40 by half a turn or less while the container 30 is temporarily attached to the discharge mechanism 70. In addition, when removing the container 30 from the discharge mechanism 70, the attachment can be released by rotating the rotating body 40 by half a turn or less, and the container 30 can be easily removed from the discharge mechanism 70 by holding the container 30 with a hand and applying some external force.

[0032] Second Embodiment A description will now be given of a discharge container 200 according to a second embodiment of the present invention. Fig. 13 is a perspective view of the discharge container 200 according to the second embodiment.

[0033] As shown in FIG. 13, the discharge container 200 according to the second embodiment is configured by combining two discharge containers 100 according to the first embodiment. The basic configuration of each discharge container of the discharge container 200 is the same as that of the first embodiment, and two rotating bodies 40 are also provided, but the plug 13C and the support member 22C are common members for the two discharge containers. In this embodiment, when attaching and detaching the container 30C, the rotating bodies 40C can be rotated individually by a predetermined angle, so that the container 30C corresponding to each rotating body 40C can be easily attached and detached. In a configuration in which two discharge containers are combined adjacent to each other, in the case of a discharge container in which the container is attached and detached by a screw type, the container is rotated to be attached and detached, but if the shape of the container is a square tube, if the containers are arranged close to each other, the adjacent containers will interfere with each other and the containers cannot be rotated. In order to rotate a square tube-shaped container, the distance between each discharge container must be increased, which will increase the size of the entire discharge container. Alternatively, it is necessary to limit the shape of the container to a cylindrical shape. The discharge container 200 according to this embodiment allows the containers 30C to be easily attached and detached regardless of the shape of the containers 30C or the distance between each container 30C, making it possible to freely select the shape of the containers 30C and increasing the freedom in design.

[0034] In this embodiment, two discharge containers are combined, but the number of discharge containers may be three or more. In addition, in this embodiment, discharge containers of the same configuration are combined, but discharge containers of different configurations can also be combined. The discharge part 10C is not limited to the configuration shown in this embodiment, and any discharge part can be attached. For example, instead of providing a pressing part for each discharge container, a common member may be used for two discharge containers, and the contents may be simultaneously discharged from each discharge container by pressing one place. The contents discharged from each discharge container may be the same or different. In addition, the discharge amount of the contents discharged from each discharge container with one push may be the same or different.

[0035] As described above, the embodiment has been described, but the above embodiment is presented as an example, and the present invention is not limited to the above embodiment. The above embodiment can be implemented in various other forms, and various combinations, omissions, substitutions, modifications, etc. can be made without departing from the gist of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are included in the scope of the invention and its equivalents described in the claims.

[0036] The discharge mechanism 70 in this embodiment is applicable not only to the discharge containers 100, 200 equipped with the pump mechanism described above, but also to a discharge container that does not have a pump mechanism and is configured to connect the discharge part 10 and the container 30 so that the contents in the container 30 can be discharged or poured out from the discharge part, for example, by tilting the entire container.
