[0009] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this specification and the drawings, components having substantially the same functional configurations are designated by the same reference numerals, and duplicated explanations will be omitted.

[0010] <Overview of container structure> An embodiment of the present invention relates to a container with a dispenser that contains and dispenses a liquid material. Hereinafter, a schematic configuration of a container with a dispenser according to an embodiment of the present invention will be described with reference to Fig. 1.

[0011] 1 is an explanatory diagram showing the external configuration of a dispenser-equipped container 1 according to one embodiment of the present invention. As shown in FIG. 1, the dispenser-equipped container 1 according to one embodiment of the present invention includes a container 20 and a dispenser 30.

[0012] (container 20) The container 20 contains a liquid. The liquid contained in the container 20 may be a liquid, a gel, or a paste. Liquids, gels, and pastes all have fluidity in common, but liquids do not have a fixed shape, while gels and pastes are semi-solid and may temporarily have a fixed shape. Specifically, the liquid contained in the container 20 may be liquid detergent, fabric softener, bleach, shampoo, rinse, conditioner, body soap, cosmetic liquid, medicine, hair dye, liquid seasoning, etc.

[0013] Such a container 20 has a container body 21 and a spout 25, as shown in FIG. 1. The container body 21 may be a bag container formed by laminating a plurality of films. The space surrounded by the plurality of films becomes the space for storing the liquid. The spout 25 is fixed to the container body 21 by being joined to the inner peripheral surface of the container body 21. Examples of the film include single-layer or multi-layer films or laminated sheets made of synthetic resins such as polyolefin, polyester, polyamide, or combinations thereof, and laminated sheets having a metal vapor deposition layer such as aluminum added thereto, but are not limited thereto.

[0014] The spout 25 has a cylindrical shape with two opposing openings. The liquid contained in the container body 21 flows into the dispenser 30 through the spout 25.

[0015] The container 20 may be detachably attached to a container holder that supports the container 20 in an upright position. The container 20 is not limited to a bag container, and may be a tube, a bottle, or the like.

[0016] (Dispenser 30) The dispenser 30 sucks up a liquid material from the container 20 and dispenses the sucked up liquid material. The dispenser 30 has a screw cap 310, a dispenser body 330, an operating lever 370, and a nozzle 380, as shown in FIG.

[0017] The screw cap 310 engages with the outer peripheral surface of the spout 25. For example, a helical protrusion may be formed on the inner peripheral surface of the screw cap 310 and the outer peripheral surface of the spout 25, and the two helical protrusions may be screwed together. This makes it difficult for the dispenser 30 to come off the container 20.

[0018] The dispenser body 330 has a grip portion 332 and a lid portion 334. The grip portion 332 is a portion that is gripped by a user. The lid portion 334 has a dome shape and is elastically deformable. For example, the lid portion 334 may be a thin-walled molded product of elastomer, rubber material, foam, or resin. The lid portion 334 forms a pump chamber that stores the liquid sucked from the container 20.

[0019] The operating lever 370 is an example of a rotating part that is rotatably attached to the dispenser body 330 between an initial position and a position where the lid part 334 is pressed. When a user presses the operating lever 370, the operating lever 370 rotates toward the lid part 334, and a convex part 372 (see FIG. 2) formed on the lower surface of the operating lever 370 presses the lid part 334. When the lid part 334 is pressed, the lid part 334 deforms, increasing the pressure in the pump chamber, and the liquid is pumped from the pump chamber to the nozzle 380.

[0020] The nozzle 380 has a discharge port 382 that is connected to the pump chamber, and discharges the liquid that has flowed in from the pump chamber from the discharge port 382.

[0021] <Dispenser configuration> The external configuration of the dispenser-equipped container 1 according to one embodiment of the present invention has been described above. Next, the configuration of the dispenser 30 according to one embodiment of the present invention will be described in detail.

[0022] Fig. 2 is a side view of dispenser 30 according to an embodiment of the present invention. Fig. 3 is a cross-sectional view of dispenser 30 according to an embodiment of the present invention. As shown in Fig. 3, an inner plug portion 320 is provided inside screw cap 310. Also, as shown in Figs. 2 and 3, dispenser body 330 has connecting tube portion 331, grip portion 332, lid portion 334, recess 335, and valve mechanism 337, and pump chamber P is formed by lid portion 334 and recess 335.

[0023] (Inner plug part 320) Inner plug portion 320 is inserted into spout 25. Inner plug portion 320 has protruding portion 321 that protrudes outwardly. Protruding portion 321 presses annular sealing member 324 against the upper end of spout 25, thereby achieving airtightness of container 20. Note that the annular shape is a shape that surrounds a certain area.

[0024] Furthermore, the inner plug portion 320 has an annular groove into which the connecting tube portion 331 fits. A valve mechanism 322 is provided in the flow path between the inner plug portion 320 and the pump chamber P. The valve mechanism 322 has a cylindrical base and a plate-shaped valve body. The valve body is connected to one axial end of the base via a connecting portion and is elastically displaceable in the axial direction relative to the base. The valve mechanism 322 prevents the liquid from flowing back from the pump chamber P to the container 20.

[0025] (Connection cylinder part 331) The connecting cylinder portion 331 has a cylindrical shape, and connects the liquid storage space of the container 20 to the pump chamber P. That is, the connecting cylinder portion 331 forms a flow path for the liquid from the container 20 to the pump chamber P.

[0026] In this specification, the direction along which the axis L of the connecting tube portion 331 is aligned or the height direction of the dispenser-equipped container 1 when the dispenser-equipped container 1 is in an upright position is referred to as the up-down direction (Z-axis direction shown in Figs. 2 and 3), the direction in which the liquid material moves from the container 20 to the pump chamber P is referred to as the up-down direction as an example of a first direction, and the opposite direction to the up-down direction is referred to as the down-down direction as an example of a second direction. In addition, the direction in which the liquid material is discharged from the discharge port 382 of the nozzle 380 is referred to as the front direction (one direction in the X-axis shown in Figs. 2 and 3), and the opposite direction is referred to as the rear direction (the opposite direction in the X-axis shown in Figs. 2 and 3). In addition, the direction perpendicular to the up-down direction and the front-rear direction is referred to as the width direction (Y-axis direction shown in Figs. 2 and 3).

[0027] 2 and 3, a plane S1 (first surface) that is a surface perpendicular to the direction of the axis L of the connecting cylindrical portion 331 is shown.

[0028] (Cover portion 334, recess portion 335) The recess 335, together with the lid 334, forms a pump chamber P for temporarily storing the liquid material flowing in from the container 20 through the connecting tube 331. The lid 334 is attached to the dispenser body 330 so as to cover the opening of the recess 335. When the lid 334 is not pressed, the lid 334 has a dome shape that is convex on the opposite side of the recess 335. With this configuration, the deformation amount of the lid 334 can be increased. The discharge amount of the liquid material changes depending on the change in the volume of the pump chamber P. The change in the volume of the pump chamber P can be easily adjusted depending on the shape of the lid 334, and as a result, the discharge amount of the liquid material can be adjusted. The shape of the opening of the recess 335 may be circular or angular. In addition, an elastic body such as a coil spring that supports the elastic deformation of the lid 334 may be provided in the pump chamber P.

[0029] 3 shows a plane S2 (second surface) along which the opening of the recess 335 is aligned. The plane S2 is inclined relative to the plane S1 so as to slope downward toward the rear. More specifically, the angle between the plane S2 and the plane S1 may be 5 degrees or more.

[0030] (Valve mechanism 337) The valve mechanism 337 is located in a flow path between the pump chamber P and the nozzle 380. The valve mechanism 337 has a cylindrical base and a plate-shaped valve body. The valve body is connected to one axial end of the base via a connecting part, and is elastically displaceable in the axial direction relative to the base. The valve mechanism 337 prevents the liquid from flowing back from the nozzle 380 to the pump chamber P. As shown in FIG. 3, the nozzle 380 is attached to the dispenser body 330 by fitting an annular groove of the nozzle 380 to an annular protrusion of the dispenser body 330.

[0031] (Operating lever 370) The operating lever 370 forms a rotation fulcrum F with the dispenser body 330, and is rotatable around the rotation fulcrum F. The rotation fulcrum F is located on the same side as the discharge port 382 with respect to a plane including the axis L of the connecting tube portion 331. In addition, the rotation fulcrum F is located on a plane that is parallel to the plane S2 and passes through the upper end of the lid portion 334, or below the plane.

[0032] 2 and 3 show plane S3, which is the plane along which the upper surface of the operating lever 370 fits. Plane S3 is inclined at 10 degrees or less with respect to plane S1 so as to slope upward as it approaches the rear. However, plane S3 may be parallel to plane S1. Furthermore, plane S3 may be inclined with respect to plane S1 so as to slope downward as it approaches the rear.

[0033] When the upper surface of operating lever 370 is a flat surface, the upper surface of operating lever 370 and plane S3 coincide with each other, but when the upper surface of operating lever 370 is a curved surface or has irregularities, plane S3 may be a plane that approximates the upper surface of operating lever 370. For example, plane S3 may be a plane that minimizes the square error of the distance between each position on the upper surface of operating lever 370 and the plane.

[0034] A protrusion 372 that presses against the lid 334 is formed on the underside of the operating lever 370. The height of the protrusion 372 is greater at a position away from the rotation fulcrum F than at a position closer to the rotation fulcrum F.

[0035] Fig. 4 is a cross-sectional view of the operating lever 370. Fig. 4 shows a height d1 of the protruding portion 372 at a position close to the rotation fulcrum F, and a height d2 of the protruding portion 372 at a position away from the rotation fulcrum F. The height d2 is greater than the height d1.

[0036] <Operation> The configuration of the dispenser 30 according to one embodiment of the present invention has been described above. Next, the operation of the dispenser 30 according to one embodiment of the present invention will be described.

[0037] Fig. 5 is an explanatory diagram showing a state in which the operating lever 370 is in a pressing position where it presses the lid part 334. When the user presses the operating lever 370 in a state in which the operating lever 370 shown in Fig. 3 etc. is in the initial position, the operating lever 370 rotates around the rotation fulcrum F, and as shown in Fig. 5, the convex part 372 moves to the pressing position where it presses the lid part 334.

[0038] Then, the volume of the pump chamber P decreases due to the elastic deformation of the cover portion 334, and the internal pressure of the pump chamber P increases. When the internal pressure of the pump chamber P becomes higher than the internal pressure of the nozzle 380 and the thrust caused by the pressure difference exceeds the elastic force of the connecting portion of the valve mechanism 337, the valve element of the valve mechanism 337 moves to open the valve mechanism 337, and the pump chamber P and the nozzle 380 communicate with each other. As a result, the liquid material flows out from the pump chamber P to the nozzle 380, and further, the liquid material is discharged from the discharge port 382, ​​as shown by the arrow in FIG.

[0039] Thereafter, when the user releases the pressure on the operating lever 370, the elastic force of the lid portion 334 causes the lid portion 334 to return towards the dome shape, and the lid portion 334 pushes the operating lever 370 back to its initial position, as shown in Fig. 6. Then, the volume of the pump chamber P increases, and the internal pressure of the pump chamber P decreases. When the internal pressure of the pump chamber P decreases and the thrust force due to the pressure difference between the internal pressure of the pump chamber P and the internal pressure of the container 20 exceeds the elastic force of the connecting portion of the valve mechanism 322, the valve element of the valve mechanism 322 moves, opening the valve mechanism 322, and the pump chamber P and the container 20 communicate with each other. As a result, the liquid flows from the container 20 into the pump chamber P via the connecting tube portion 331.

[0040] <Action and effect> According to the embodiment of the present invention described above, various operational effects can be obtained. For example, in one embodiment of the present invention, the plane S3 along which the upper surface of the operating lever 370 is aligned is inclined at 10 degrees or less with respect to the plane S1 so as to move upward toward the rear. Alternatively, the plane S3 may be parallel to the plane S1, or may be inclined with respect to the plane S1 so as to move downward toward the rear. According to this configuration, the height of the dispenser 30 is more likely to be reduced than when the plane S3 is inclined at more than 10 degrees with respect to the plane S1 so as to move upward toward the rear. Therefore, according to one embodiment of the present invention, the dispenser 30 can be made smaller in size.

[0041] In one embodiment of the present invention, plane S2 along which the opening of recess 335 runs is inclined relative to plane S1 so as to slope downward toward the rear. With this configuration, it is possible to ensure a wider movable range for rotation of operating lever 370 compared to a case in which plane S2 is parallel to plane S1. As a result, it is possible to increase the amount of liquid material dispensed with one operation of operating lever 370. This effect is more noticeable when the angle between plane S2 and plane S1 is 5 degrees or more.

[0042] Moreover, in one embodiment of the present invention, with respect to the protrusion 372 of the operating lever 370, the height d2 of the protrusion 372 at a position away from the rotation fulcrum F is greater than the height d1 of the protrusion 372 at a position closer to the rotation fulcrum F. The advantages of this configuration will be described with reference to FIG. 6.

[0043] FIG. 6 is an explanatory diagram showing a comparative example. The convex portion 375 of the operating lever 371 according to the comparative example has the same height at a position away from the rotation fulcrum F and at a position close to the rotation fulcrum F. In this case, as shown in FIG. 6, the variation in the amount of deformation of the lid portion 334 in the front-rear direction increases, and the pressing force of the lid portion 334 is also shallow. In contrast, according to the above-mentioned configuration of one embodiment of the present invention, as shown in FIG. 5, the convex portion 372 can press the lid portion 334 more uniformly and more deeply. Note that the convex portion 375 may not be provided on the lower surface of the operating lever 371, and the lower surface of the operating lever 371 may be used as it is to press the lid portion 334. By forming the convex portion 375 protruding toward the lid portion 334 on the lower surface of the operating lever 371 and making the convex portion 375 press the lid portion 334, it becomes easy to effectively press the lid portion 334 as described above.

[0044] In one embodiment of the present invention, the rotation fulcrum F of the operating lever 370 is located on the same side as the discharge port 382 with respect to a plane including the axis L of the connecting tube portion 331. With this configuration, the force point, which is the operating part of the user with respect to the operating lever 370, is located on the opposite side of the discharge port 382 with respect to a plane including the axis L of the connecting tube portion 331, improving operability. In particular, it is easy for the user to operate the dispenser 30 with one hand. Note that the inclination of the upper surface of the operating lever 370 described above also reduces the distance between the grip portion 332 and the operating part of the user, improving operability.

[0045] In one embodiment of the present invention, the rotation fulcrum F of the operating lever 370 is parallel to the plane S2 along which the opening of the recess 335 lies, and is located on a plane passing through the upper end of the cover 334, or below said plane. The advantages of this configuration will be described with reference to FIG. 7.

[0046] 7 is an explanatory diagram that shows a schematic diagram of the operating lever 370 and the lid portion 334. In FIG. 7, the solid line shows the arrangement of the operating lever 370 when the rotation fulcrum F is parallel to the plane S2 along which the opening of the recess 335 is aligned and is located below the plane S5 passing through the upper end of the lid portion 334, and the two-dot chain line shows the arrangement of the operating lever 370 when the rotation fulcrum F is parallel to the plane S2 along which the opening of the recess 335 is aligned and is located above the plane S5 passing through the upper end of the lid portion 334. Comparing the two arrangements, in the arrangement shown by the two-dot chain line, the operating position (point of force) of the user with respect to the operating lever 370 approaches the plane S5 in the initial position of the operating lever 370, and in some cases is located below the plane S5, so that the amount by which the operating lever 370 pushes the lid portion 334 tends to be small. In contrast, according to the arrangement shown by the solid lines, the force point can be positioned away from the plane S5 in the initial position of the operating lever 370, so that the rotational range of the operating lever 370 is wider, making it possible to ensure a larger amount of liquid to be dispensed, and by positioning the rotation fulcrum F further downward, the height of the dispenser 30 can be reduced.

[0047] From another perspective, when plane S2 (plane S5) is nearly parallel to plane S1 (for example, the inclination angle of plane S2 with respect to plane S1 is less than 5 degrees), rotation fulcrum F may be located below the upper end of cover portion 334 or may be at the same position in the up-down direction as the upper end of cover portion 334. When plane S2 (plane S5) is inclined with respect to plane S1 so as to be downward as it moves rearward (for example, the inclination angle is 5 degrees or more), the above-mentioned effect can be significantly manifested.

[0048] <Application Examples> An embodiment of the present invention has been described above. Next, an application example of the embodiment of the present invention will be described.

[0049] Fig. 8 is an explanatory diagram showing the appearance of a dispenser-equipped container 2 according to an application example. As shown in Fig. 8, the dispenser-equipped container 2 according to the application example includes a plurality of containers 20 and a dispenser 30-2. The dispenser 30-2 has a plurality of screw caps 310, a dispenser body 330-2, an operating lever 370-2, and a nozzle 380-2.

[0050] The dispenser body 330-2 has a plurality of lid parts 334. That is, the dispenser body 330-2 has a plurality of pump chambers P. Each pump chamber P is connected to one of the containers 20 and sucks liquid material from the connected container 20. The plurality of lid parts 334 may be arranged along the width direction as shown in FIG. 8, or along the front-rear direction. This allows a single dispenser to dispense a plurality of liquid materials and mix them for use.

[0051] The operating lever 370-2 has a plurality of protrusions 372. Each protrusion 372 presses one of the lid portions 334. When a user presses the operating lever 370-2 and the operating lever 370-2 rotates, each protrusion 372 presses the plurality of lid portions 334 simultaneously.

[0052] Further, an identification portion 376 is formed on the upper surface of the operating lever 370-2. The identification portion 376 is a portion that is distinguished from other portions on the upper surface of the operating lever 370-2. A user can recognize the identification portion 376 as an operating position and operate the operating lever 370-2. The identification portion 376 may be a recess or a mark formed by printing.

[0053] Furthermore, the identifier 376 may be formed at a portion equidistant from each of the multiple pump chambers P so that each lid portion 334 is pressed evenly. For example, as shown in Fig. 8, the identifier 376 may be a tapered portion at the tip of the operating lever 370-2, and may be formed at the center position in the width direction of the two pump chambers P. This makes it easy to discharge an equal amount of liquid from each pump chamber P.

[0054] Note that one pressing member that presses the lid portion 334 may be provided for each pump chamber P. In this case, the liquid material can be discharged simultaneously from each pump chamber P. The pressing member may be a cylinder with a guide member or a lever, and from the viewpoint of discharging an equal amount of the liquid material from each pump chamber P, it is desirable that the movable range of each pressing member is the same.

[0055] The nozzle 380-2 has a plurality of outlets 382. Each outlet 382 is connected to one of the pump chambers P, and each outlet 382 discharges the liquid material pressure-fed from the pump chamber P to which it is connected. When there is only one outlet 382 and the liquid materials pressure-fed from the plurality of pump chambers P join before the outlet 382, ​​the two liquid materials may be mixed and remain in a state of chemical reaction in the flow path from the joining point to the outlet 382. In this case, a mixture that does not exhibit its original performance will be discharged at the next use. In contrast, the dispenser-equipped container 2 according to the application example has a plurality of outlets 382, ​​making it possible to suppress the generation of a mixture with reduced performance.

[0056] The above-mentioned designs of the plane S2, plane S3, and rotation fulcrum F are also applied to the dispenser-equipped container 2 according to this application example. Therefore, the dispenser-equipped container 2 according to the application example can obtain substantially the same effects as those of the above-mentioned embodiment. For example, the dispenser-equipped container 2 according to the application example can also achieve miniaturization of the dispenser 30-2 and improvement in the operability of the dispenser 30-2.

[0057] The container with dispenser 2 may be detachably attached to a container holder 40 as shown in Fig. 9. The container holder 40 has a tubular portion in which an opening 42 is formed, and a top surface 44. The edge of the top surface 44 fits into a groove formed in the spout 25 of the container 20, whereby the container with dispenser 2 is supported in an upright position by the container holder 40. A user can attach the container with dispenser 2 to the container holder 40 by inserting the container body 21 into the container holder 40 through the opening 42, and can remove the container with dispenser 2 from the container holder 40 by pulling out the container body 21 from the container holder 40 through the opening 42.

[0058] <Supplementary Information> Although the preferred embodiment of the present invention has been described in detail above with reference to the attached drawings, the technical scope of the present invention is not limited to such examples. It is clear that a person having ordinary knowledge in the technical field of the present invention can conceive of various modified or altered examples within the scope of the technical ideas described in the claims, and it is understood that these also naturally belong to the technical scope of the present invention.
