Summary of the Invention
Problems to be Solved by the Invention
[0004] However, in the conventional dispenser with a tray member, when impregnating a wide range of the impregnating body with the content, for example, it is necessary to perform a discharge operation multiple times while changing the position of the impregnating body with respect to the discharge hole.
[0005] The present invention provides a dispenser with a tray member that can easily and selectively impregnate the content into both a narrow range and a wide range of the impregnating body.
Means for Solving the Problems
[0006] A discharger with a receiving tray according to one aspect of the present invention comprises a pump mechanism attached to the mouth of a container body containing contents, having a stem arranged to be movable downward in an upward biased state, and a receiving tray member attached to the upper end of the stem, wherein the receiving tray member comprises a mounting cylinder portion attached to the upper end of the stem, a lower tray portion protruding radially outward from the upper end of the mounting cylinder portion and having a discharge hole in its radial center that communicates with the inside of the stem, and an upper tray portion attached to the upper surface of the lower tray portion and located radially inward from the outer peripheral edge of the lower tray portion, wherein the radial center of the upper tray portion has a slit and protruding downward, the slit A valve cylinder is formed around the entire circumference of the upper plate portion, and in the radial intermediate portion of the upper plate portion located radially outward from the valve cylinder, a plurality of communication holes penetrating vertically are formed at circumferential intervals, and a vertical gap is provided between the radial central portion of the upper plate portion, the valve cylinder, the radial intermediate portion of the upper plate portion and the upper surface of the lower plate portion, and the radial central portion of the upper plate portion is provided to be elastically displaceable vertically, and a flow path is provided in the outer circumference located radially outward from the communication holes between the lower surface of the upper plate portion and the upper surface of the lower plate portion, from the gap to the outer edge of the upper plate portion.
[0007] When the outer edge of the lower dish, which protrudes radially outward from the outer edge of the upper dish, is pressed down, the stem is also pressed down, and the contents that have passed through the stem are discharged from the discharge hole of the lower dish toward the lower surface of the radial center of the upper dish. In this configuration, a slit and a valve cylinder are formed in the radial center of the upper plate portion. Multiple vertically penetrating communication holes are formed in the radially intermediate portion of the upper plate portion, located radially outside the valve cylinder, at circumferential intervals. A vertical gap is provided between the radial center of the upper plate portion, the valve cylinder, the radially intermediate portion of the upper plate portion, and the upper surface of the lower plate portion. Between the lower surface of the upper plate portion and the upper surface of the lower plate portion, a flow path is provided in the outer circumference located radially outside the communication holes, extending from the gap to the outer edge of the upper plate portion. Therefore, the contents discharged toward the lower surface in the radial center of the upper plate portion reach the upper surface of the upper plate portion through the slit and multiple communication holes, and also reach the outer edge of the upper plate portion through the flow path and ride up onto the upper surface of the upper plate portion, thereby ensuring that the contents reach a wide area of the upper surface of the upper plate portion. In the process described above, if an impregnating material such as cotton is pressed against the upper surface of the upper tray, the contents that reach the upper surface of the upper tray will be impregnated over a wide area by the impregnating material. On the other hand, when the radial center of the upper plate is pressed down and elastically displaced, the lower end of the valve cylinder is pressed against the upper surface of the lower plate, blocking communication between the discharge hole, the communication hole, and the flow path. In this state, when the receiving plate member is pressed down together with the stem, the contents that pass through the stem and are discharged from the discharge hole toward the lower surface of the radial center of the upper plate do not reach the communication hole and flow path, but pass upward only through the slit and reach the upper surface of the upper plate. In the above process, if the impregnating material is pressed against the upper surface of the upper plate, the contents that reach the upper surface of the upper plate will be impregnated only in a narrow area of the impregnating material.
[0008] A recess is formed on the upper surface of the outer periphery of the lower dish portion, accommodating the outer periphery of the upper dish portion. The inner surface of the recess is located radially outward from the outer edge of the upper dish portion. The flow path is defined by a first groove formed on the bottom surface of the recess and the lower surface of the outer periphery of the upper dish portion covering the first groove. The radial outer end of the first groove is located radially outward from the outer edge of the upper dish portion. A second groove may be formed on the outer periphery of the bottom surface of the recess, which is connected to the inner surface of the recess, extending circumferentially from the radial outer end of the first groove.
[0009] A recess is formed on the upper surface of the outer circumference of the lower pan portion, accommodating the outer circumference of the upper pan portion. The flow path is defined by a first groove formed on the bottom surface of the recess and the lower surface of the upper pan portion covering the first groove. The radial outer end of the first groove is located radially outward from the outer edge of the upper pan portion, and a second groove is formed on the outer edge of the bottom surface of the recess, extending circumferentially from the radial outer end of the first groove. Therefore, when the outer edge of the lower dish, which protrudes radially outward from the outer edge of the upper dish, is pushed down together with the stem, and the contents are discharged from the discharge hole of the lower dish toward the lower surface at the radial center of the upper dish, the contents that reach the outer edge of the upper dish through the flow path pass through the radial outer end of the first groove, then collide with the inner surface of the recess, enter the second groove, and flow circumferentially along the inner surface of the recess, making it easier to distribute the contents over a wide area of the outer edge of the upper dish.
[0010] The second groove may straddle the outer peripheral edge of the upper plate in the radial direction.
[0011] Since the second groove spans the outer edge of the upper pan in the radial direction, it becomes easier to introduce the contents that have reached the radial outer end of the flow path into the second groove, and thus it becomes easier to ensure that the contents are distributed reliably over a wide area of the outer edge of the upper pan. [Effects of the Invention]
[0012] According to one aspect of the present invention, the contents can be selectively and easily impregnated into both a narrow and a wide area of the impregnated body. [Brief explanation of the drawing]
[0013] [Figure 1] This is a longitudinal cross-sectional view of a discharger with a receiving tray, as shown as one embodiment. [Figure 2] This is a partially enlarged view of Figure 1. [Figure 3] This is a top view of Figure 2. [Figure 4] Figure 2 shows the upper pan portion in a state where the radial center is pressed down.
Best Mode for Carrying Out the Invention
[0014] Hereinafter, referring to the drawings, a saucer-equipped discharger according to an embodiment of the present invention will be described. As shown in FIG. 1, the saucer-equipped discharger 1 according to the present embodiment includes a pump mechanism 11 and a saucer member 12.
[0015] The pump mechanism 11 includes a stem 13, a cylinder 14, a piston 15, and a biasing member 16.
[0016] The stem 13, the cylinder 14, the piston 15, and the biasing member 16 are arranged coaxially with a common axis. Hereinafter, the common axis is referred to as the central axis O, one end side of the stem 13 along the central axis O is referred to as upward, the other end side of the cylinder 14 along the central axis O is referred to as downward, and the direction along the central axis O is referred to as the vertical direction. The direction intersecting the central axis O as viewed from the vertical direction is referred to as the radial direction, and the direction orbiting around the central axis O as viewed from the vertical direction is referred to as the circumferential direction. The cylinder 14 is attached to the mouth portion W1 of the container body W in which the content is accommodated via a mounting cap C. The stem 13 protrudes upward from within the cylinder 14 and is supported by the biasing member 16 so as to be movable downward in an upwardly biased state. The piston 15 is provided in the cylinder 14 so as to be slidable vertically and is linked to the vertical movement of the stem 13. The stem 13 is upwardly biased by the biasing member 16 via the piston 15.
[0017] The saucer member 12 includes a mounting cylinder portion 21, a lower saucer portion 22, and an upper saucer portion 23.
[0018] The mounting cylinder portion 21 is formed of a synthetic resin material or the like and is mounted on the upper end portion of the stem 13. The mounting cylinder portion 21 is externally fitted on the upper end portion of the stem 13. The upper end portion of the mounting cylinder portion 21 is located above the upper end portion of the stem 13. As shown in FIG. 2, on the inner peripheral surface of the upper end portion of the mounting cylinder portion 21, a plurality of ribs 21a are formed at intervals in the circumferential direction, protruding radially inward and having front and back surfaces facing the circumferential direction. The lower end surface of the rib 21a abuts against the upper end opening edge of the stem 13.
[0019] The lower dish portion 22 is formed of a synthetic resin material or the like and protrudes radially outward from the upper end portion of the mounting cylinder portion 21. The lower dish portion 22 has a rectangular shape that is long in one direction in the radial direction when viewed from the vertical direction, as shown in FIG. 3. When viewed from the vertical direction, the central axis O is located at the center of the lower dish portion 22. That is, the lower dish portion 22 is arranged coaxially with the central axis O. As shown in FIG. 2, a discharge hole 24 that penetrates in the vertical direction and communicates with the inside of the stem 13 is formed at the radial center of the lower dish portion 22. The discharge hole 24 is arranged coaxially with the central axis O.
[0020] A flat plate 24a with front and back surfaces facing the vertical direction is provided in the discharge hole 24. The outer peripheral surface of the flat plate 24a is separated radially inward from the inner peripheral surface of the discharge hole 24. The upper end surface of the rib 21a is connected to the outer peripheral edge portion of the lower surface of the flat plate 24a. The flat plate 24a and the rib 21a are integrally formed. A rod-shaped protrusion 24b that extends downward and is inserted into the upper end portion of the stem 13 is formed at the radial center of the lower surface of the flat plate 24a. The lower end portion of the protrusion 24b is located below the rib 21a. The protrusion 24b is arranged coaxially with the central axis O.
[0021] The lower dish portion 22 is composed of an inner peripheral portion 22a formed in a flat plate shape with front and back surfaces facing the vertical direction, and an outer peripheral portion 22b that extends upward as it goes radially outward from the inner peripheral portion 22a. The outer peripheral portion 22b is formed in a curved surface shape with the upper surface recessed downward and the lower surface bulging downward. The upper surface of the inner peripheral portion 22a is located below the upper surface at the radially inner end of the outer peripheral portion 22b.
[0022] A recess 26 is formed on the upper surface of the outer periphery 22b of the lower pan portion 22, which accommodates the outer periphery 23b of the upper pan portion 23. The inner periphery 26a of the recess 26 is located radially outward from the outer periphery edge 23c of the upper pan portion 23. When viewed from above, the recess 26 has a rectangular shape that is elongated in one radial direction. A bottomed cylindrical mounting tube 25 is provided at the radial inner end of the outer circumference 22b of the lower plate portion 22, opening into the bottom surface 26b of the recess 26 and protruding downward from the lower surface of the lower plate portion 22. Multiple mounting tubes 25 (four in the illustrated example) are provided at equal intervals in the circumferential direction.
[0023] The upper plate portion 23 is made of a softer material than the material forming the lower plate portion 22, such as a soft material (elastomer), and is attached to the upper surface of the lower plate portion 22. It is located radially inward from the outer peripheral edge 22c of the lower plate portion 22. Leg portions 33 are formed at the radial inner end of the outer peripheral portion 23b of the upper plate portion 23, protruding downward and fitted and fixed inside the mounting cylinder 25 of the lower plate portion 22. Multiple legs 33 (four in the illustrated example) are provided at equal intervals in the circumferential direction. The circumferential positions of the legs 33 and the mounting cylinder 25 are the same as those of the other. The upper pan portion 23 has a rectangular shape that is elongated in one radial direction when viewed from above. The top view shapes of the upper pan portion 23, the recess 26, and the lower pan portion 22 are similar, with the upper pan portion 23 being the smallest and the lower pan portion 22 being the largest.
[0024] A slit 27 and a valve cylinder 28 that protrudes downward and surrounds the slit 27 and the discharge hole 24 around its entire circumference are formed in the radial center of the upper plate portion 23. In the upper plate portion 23, in the radially intermediate portion located radially outward from the valve cylinder 28, a plurality of communication holes 29 that penetrate vertically are formed at circumferential intervals.
[0025] The connection portion (referred to as the elastically deformable portion 23d) between the radially central portion and the radially intermediate portion of the upper plate portion 23 extends downward as it moves radially outward and is formed to be elastically deformable. The elastically deformable portion 23d is formed in an annular shape and is arranged coaxially with the central axis O. When the radial center of the upper plate portion 23 is pressed, the elastic deformation portion 23d elastically deforms, causing the radial center of the upper plate portion 23 to elastically displace downward, as shown in Figure 4. In other words, the radial center of the upper plate portion 23 is provided to be elastically displaceable in the vertical direction.
[0026] A portion of the slit 27 faces the discharge hole 24 in the vertical direction. The slit 27 extends radially and is provided in multiple locations, intersecting each other along the central axis O. The valve cylinder 28 is formed to be elastically deformable and extends continuously around its entire circumference. The valve cylinder 28 is arranged coaxially with the central axis O. The valve cylinder 28 extends radially inward as it extends downward. The wall thickness of the valve cylinder 28 decreases as it extends downward. The lower end edge of the valve cylinder 28 extends along the upper surface of the inner circumference 22a of the lower dish portion 22 in a vertical cross-sectional view along the vertical direction.
[0027] A vertical gap X is provided between the radial central portion of the upper plate portion 23, the valve cylinder 28, the radial intermediate portion of the upper plate portion 23, and the upper surface of the lower plate portion 22. Between the lower surface of the upper plate portion 23 and the upper surface of the lower plate portion 22, a flow path 20 is provided on the outer circumference located radially outside the communication hole 29, extending from the gap X to the outer peripheral edge 23c of the upper plate portion 23. The flow channels 20 are provided between the bottom surface 26b of the recess 26 of the lower dish portion 22 and the bottom surface of the outer peripheral portion 23b of the upper dish portion 23. Multiple flow channels 20 (four in the illustrated example) are provided at intervals in the circumferential direction and extend radially outward from the gap X. As shown in Figure 3, the radial outer ends of each of the four flow channels 20 are each located at the four corners of the outer peripheral edge 23c of the upper dish portion 23.
[0028] The flow path 20 is defined by a first groove 31 formed on the bottom surface 26b of the recess 26 of the lower dish portion 22, and the lower surface of the outer peripheral portion 23b of the upper dish portion 23 that covers the first groove 31. The radial outer end 31a of the first groove 31 is located radially outward from the outer peripheral edge 23c of the upper plate portion 23, and is located on the outer peripheral edge of the bottom surface 26b of the recess 26 that is connected to the inner peripheral surface 26a of the recess 26. A second groove 32 is formed on the outer peripheral edge of the bottom surface 26b of the recess 26, extending circumferentially from the radial outer end 31a of the first groove 31.
[0029] The second grooves 32 extend separately from the radial outer ends 31a of each of the multiple first grooves 31 in the circumferential direction on both sides. The second grooves 32 extend along the inner circumferential surface 26a of the recess 26 when viewed from above. The length of the second grooves 32 is shorter than the length of the first grooves 31. The depth of the second grooves 32 is the same as the depth of the first grooves 31. The first grooves 31 and the two second grooves 32 extending separately from the radial outer ends 31a of the first grooves 31 in the circumferential direction on both sides exhibit an arrow shape when viewed from above, pointing to the corners of the outer circumferential edge 22c of the lower dish portion 22. The radially inner portion of the second groove 32 is covered by the upper plate portion 23, and the radially outer portion of the second groove 32 is located radially outside the outer peripheral edge 23c of the upper plate portion 23 and opens upward. In other words, the second groove 32 straddles the outer peripheral edge 23c of the upper plate portion 23 in the radial direction.
[0030] As described above, with the discharger 1 with a receiving tray according to this embodiment, when the outer edge 22c of the lower tray portion 22, which protrudes radially outward from the outer edge 23c of the upper tray portion 23, is pushed down, the stem 13 is also pushed down, and the contents that have passed through the stem 13 are discharged from the discharge hole 24 of the lower tray portion 22 toward the lower surface of the radially central part of the upper tray portion 23. In this configuration, a slit 27 and a valve cylinder 28 are formed in the radial center of the upper plate portion 23. Multiple communication holes 29, which penetrate vertically, are formed in the radial intermediate portion of the upper plate portion 23 located radially outside the valve cylinder 28, spaced apart in the circumferential direction. A vertical gap X is provided between the radial center of the upper plate portion 23, the valve cylinder 28, the radial intermediate portion of the upper plate portion 23, and the upper surface of the lower plate portion 22. Between the lower surface of the upper plate portion 23 and the upper surface of the lower plate portion 22, a flow path 20 is provided on the outer circumference located radially outside the communication holes 29, extending from the gap X to the outer peripheral edge 23c of the upper plate portion 23. Therefore, the contents discharged toward the lower surface at the radial center of the upper pan portion 23 reach the upper surface of the upper pan portion 23 through the slit 27 and the multiple communication holes 29, and also reach the outer peripheral edge 23c of the upper pan portion 23 through the flow path 20 and ride up onto the upper surface of the upper pan portion 23, thereby ensuring that the contents reach a wide area of the upper surface of the upper pan portion 23. In the above process, if an impregnating material such as cotton is pressed against the upper surface of the upper pan portion 23, the contents that reach the upper surface of the upper pan portion 23 will be impregnated over a wide area by the impregnating material.
[0031] On the other hand, as shown in Figure 4, when the radial center of the upper plate portion 23 is pressed down and elastically displaced, the lower end of the valve cylinder 28 is pressed against the upper surface of the lower plate portion 22, blocking communication between the discharge hole 24 and the communication hole 29 and the flow path 20. In this state, when the receiving plate member 12 is pressed down together with the stem 13, the contents that pass through the stem 13 and are discharged from the discharge hole 24 toward the lower surface of the radial center of the upper plate portion 23 do not reach the communication hole 29 and the flow path 20, but pass upward only through the slit 27 and reach the upper surface of the upper plate portion 23. In the above process, if the impregnating body is pressed against the upper surface of the upper plate portion 23, the contents that reach the upper surface of the upper plate portion 23 will be impregnated only in a narrow area of the impregnating body.
[0032] A recess 26 is formed on the upper surface of the outer periphery 22b of the lower dish portion 22, accommodating the outer periphery 23b of the upper dish portion 23. The flow path 20 is defined by a first groove 31 formed on the bottom surface 26b of the recess 26 and the lower surface of the upper dish portion 23 covering the first groove 31. The radial outer end 31a of the first groove 31 is located radially outward from the outer periphery 23c of the upper dish portion 23, and a second groove 32 is formed on the outer periphery of the bottom surface 26b of the recess 26, extending circumferentially from the radial outer end 31a of the first groove 31. Therefore, when the outer periphery 22c of the lower dish portion 22, which protrudes radially outward from the outer periphery 23c of the upper dish portion 23, is pushed down together with the stem 13, and the contents are discharged from the discharge hole 24 of the lower dish portion 22 toward the lower surface at the radial center of the upper dish portion 23, the contents that reach the outer periphery 23c of the upper dish portion 23 through the flow path 20 pass through the radial outer end 31a of the first groove portion 31, then collide with the inner circumferential surface 26a of the recess 26, enter the second groove portion 32, and flow circumferentially along the inner circumferential surface 26a of the recess 26, making it easier to distribute the contents over a wide area of the outer periphery 23c of the upper dish portion 23.
[0033] Since the second groove 32 spans the outer peripheral edge 23c of the upper pan portion 23 in the radial direction, it becomes easier to introduce the contents that have reached the radial outer end of the flow path 20 into the second groove 32, and it becomes easier to ensure that the contents are spread reliably over a wide area of the outer peripheral edge 23c of the upper pan portion 23.
[0034] Furthermore, the technical scope of the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention.
[0035] For example, it is not necessary to form a recess 26 on the upper surface of the outer peripheral portion 22b of the lower plate portion 22, nor is it necessary to form a second groove 32 on the outer peripheral edge of the bottom surface 26b of the recess 26. The second groove 32 may be located radially outward from the outer peripheral edge 23c of the upper plate portion 23 throughout its entire area. The top view shapes of the upper plate portion 23, the recessed portion 26, and the lower plate portion 22 may be, for example, circular, or they may be different from each other.
[0036] Furthermore, without departing from the spirit of the present invention, the components in the above embodiments may be replaced with well-known components as appropriate, and the above embodiments and modifications may be combined as appropriate. [Explanation of Symbols]
