Mode for Carrying Out the Invention

[0017] Hereinafter, a pump-type discharging tool according to an embodiment of the present invention will be described in detail with reference to the drawings.

[0018] As shown in FIG. 1, a pump-type discharging tool 1 according to an embodiment of the present invention includes a mounting cap 10, a pump 20, a pressing head 30, and a stopper member 40.

[0019] The pump-type discharging tool 1 is used by being attached to the mouth portion 2a of a container body 2 that stores a liquid. The discharging container 3 is constituted by the pump-type discharging tool 1 and the container body 2. The pump-type discharging tool 1 is configured such that when the pressing head 30 is pushed down, the pump 20 operates to discharge the liquid inside the container body 2 from the nozzle 32 of the pressing head 30 to the outside.

[0020] In the present specification and claims, the vertical direction means the vertical direction in a state where the pump-type discharging tool 1 to the discharging container 3 is in the upright posture shown in FIG. 1.

[0021] As the container body 2 to which the pump-type discharging tool 1 is attached, various shapes or configurations capable of storing a liquid such as hand soap, body soap, shampoo, facial cleanser, etc. inside can be used. In the present embodiment, the container body 2 is a bottle container made of synthetic resin. The mouth portion 2a of the container body 2 is cylindrical with the axis O as the center, and is open upward at the upper end of the container body 2.

[0022] The mounting cap 10 is a top-cylindrical shape having a cylindrical portion 11 centered on an axis O and a top wall portion 12 connected to the upper end of the cylindrical portion 11, and is attached to the mouth portion 2a by screw connection. In this embodiment, a support cylinder portion 13 is integrally provided on the upper surface of the top wall portion 12, which is cylindrical centered on an axis O and protrudes upward from the top wall portion 12. As shown in Figure 2, an annular support projection 13a protruding radially outward is integrally provided on the outer circumferential surface of the upper end portion of the support cylinder portion 13.

[0023] As shown in Figure 1, the pump 20 is supported by the mounting cap 10 and suspended inside the container body 2. The pump 20 has a stem 21 positioned along the axis O. The stem 21 protrudes above the top wall portion 12 of the mounting cap 10. When the stem 21 moves downward from the initial position shown in Figure 1, the pump 20 performs a discharge operation, pumping the liquid inside from the stem 21 towards the push-down head 30. After the discharge operation, when the stem 21 moves upward towards the initial position, the pump 20 performs a suction operation, drawing the liquid inside the container body 2 into the container body 2 through a suction pipe 22 that extends towards the bottom of the container body 2.

[0024] The push-down head 30 comprises an inverted dish-shaped head body 31 and a nozzle 32 that protrudes radially outward from the head body 31 around axis O. The push-down head 30 is attached to the upper end of the stem 21. The nozzle 32 communicates with the internal flow path of the stem 21, and its tip is a liquid discharge port 32a.

[0025] When the push-down head 30 is pushed down, the stem 21 is pushed down along with the push-down head 30. Therefore, when the push-down head 30 is pushed down, the pump 20 is activated and the liquid inside the container body 2 is discharged to the outside from the nozzle 32 (discharge port 32a) of the push-down head 30.

[0026] The stopper member 40 is detachably mounted between the mounting cap 10 and the push-down head 30. When the stopper member 40 is mounted between the mounting cap 10 and the push-down head 30, the push-down head 30 is supported by the mounting cap 10 via the stopper member 40. This prevents the push-down head 30 from moving downward. On the other hand, when the stopper member 40 is removed from between the mounting cap 10 and the push-down head 30, the support of the push-down head 30 by the mounting cap 10 via the stopper member 40 is released, and the push-down head 30 is allowed to move downward. Therefore, by removing the stopper member 40 from between the mounting cap 10 and the push-down head 30, the push-down head 30 can be pressed down.

[0027] As shown in Figure 2, in this embodiment, the push-down head 30 has a skirt portion 33 that is formed in a cylindrical shape centered on the axis O of the mounting cap 10 and protrudes downward from the head body portion 31. An annular supported projection 33a is integrally provided on the inner circumferential surface of the lower end portion of the skirt portion 33, protruding radially inward and facing the support projection 13a of the support cylinder portion 13. The lower end surface of the supported projection 33a is at the same height as the lower end surface of the support projection 13a. The skirt portion 33 is protected from radial rattle by the fact that the supported projection 33a is supported by the support projection 13a of the support cylinder portion 13. Alternatively, the skirt portion 33 may be configured so that the support projection 13a of the support cylinder portion 13 directly contacts the inner circumferential surface of the lower end portion of the skirt portion 33, without providing the supported projection 33a on the skirt portion 33.

[0028] As shown in Figure 3, the stopper member 40 is formed of a C-shaped elastic body (made of synthetic resin in this embodiment) having a slit portion 41. That is, the stopper member 40 is a C-shaped body that is elastically deformable so as to increase or decrease the opening width of the slit portion 41 by providing a slit portion 41 that divides a part of a cylindrical elastic body in the circumferential direction. The stopper member 40 has the same diameter as the skirt portion 33, and the opening width of the slit portion 41 is narrower than the outer diameter of the support cylinder portion 13. Multiple ribs 42 may be provided on the inner circumferential surface of the stopper member 40 at intervals in the circumferential direction.

[0029] As shown in Figure 2, in this embodiment, the stopper member 40 is detachably mounted on the outside of the support cylinder portion 13 between the top wall portion 12 of the mounting cap 10 and the lower end of the skirt portion 33 of the push-down head 30. When the stopper member 40 is mounted on the outside of the support cylinder portion 13, the multiple ribs 42 come into contact with the outer circumferential surface of the support cylinder portion 13, thereby holding the stopper member 40 in a position coaxial with the support cylinder portion 13 or the skirt portion 33.

[0030] Since the stopper member 40 is C-shaped and elastically deformable to increase or decrease the opening width of the slit portion 41, it can be removed from the support cylinder portion 13 by pulling it radially outward around the axis O to increase the opening width of the slit portion 41. Conversely, the stopper member 40 can be attached to the support cylinder portion 13 by pressing the slit portion 41 against the side surface of the support cylinder portion 13 radially inward around the axis O to increase the opening width of the slit portion 41.

[0031] As shown in Figure 2, the push-down head 30 is provided with a fitting portion 34. In this embodiment, the fitting portion 34 is integrally provided on the outer circumferential surface of the skirt portion 33. On the other hand, as shown in Figures 2 and 3, the stopper member 40 is integrally provided with a fitted portion 43 that can be fitted into the fitting portion 34. As shown in Figure 4, after removing the stopper member 40 from between the mounting cap 10 and the push-down head 30 (support cylinder portion 13), the fitted portion 43 can be fitted into the fitting portion 34. As shown in Figures 5 and 6, when the fitted portion 43 is fitted into the fitting portion 34, the stopper member 40 is attached to the push-down head 30 and becomes a hook portion for suspension.

[0032] In other words, by hooking the stopper member 40 onto a handrail or hook installed in the bathroom, for example, the discharge container 3 using the pump-type discharger 1 can be stored while suspended from the handrail or hook. Furthermore, with the pump-type discharger 1 of this embodiment, since the discharge container 3 using the pump-type discharger 1 can be stored while suspended from a handrail or hook, the growth of mold on the bottom of the container body 2 can be suppressed.

[0033] As described above, in the pump-type dispensing device 1 of this embodiment, a stopper member 40 is installed between the mounting cap 10 and the push-down head 30 to prevent the push-down head 30 from moving downward. In this configuration, a fitted portion 43 that can be fitted into a fitting portion 34 provided on the push-down head 30 is integrally provided on the stopper member 40. Therefore, by removing the stopper member 40 from between the mounting cap 10 and the push-down head 30 and fitting the fitted portion 43 into the fitting portion 34, the stopper member 40 can function as a hanging hook for suspending the pump-type dispensing device 1 from a handrail or hook. Thus, without increasing the number of parts, the dispensing container 3 using the pump-type dispensing device 1 can be used by suspending it from a handrail or hook. Furthermore, the cost of this pump-type dispensing device 1 can be reduced.

[0034] As shown in Figures 2 and 6, in this embodiment, the fitting portion 34 is groove-shaped and extends in the vertical direction. More specifically, the fitting portion 34 is groove-shaped and provided inside a stepped portion 35 which is integrally provided on the outer circumferential surface of the skirt portion 33 and protrudes radially outward. The fitting portion 34 has a vertically elongated slit-shaped opening 34a and an internal space 34b with a circular arc cross-section that is connected to the inside of the opening 34a, and its cross-sectional shape is T-shaped, where the circumferential width of the opening 34a is narrower than the circumferential width of the internal space 34b.

[0035] In contrast, as shown in Figures 2, 3, and 6, in this embodiment, the fitted portion 43 is a projection extending tangentially from the outer circumferential surface of one end of the stopper member 40. More specifically, the fitted portion 43 has a T-shaped cross-section, comprising an arc-shaped insertion portion 43a that extends tangentially from the stopper member 40 and corresponds to the internal space 34b of the fitted portion 34, and a plate-shaped connecting portion 43b with a width corresponding to the opening 34a of the fitted portion 34, connected between the insertion portion 43a and the outer circumferential surface of the stopper member 40.

[0036] As shown in Figure 4, the fitted portion 43 of the above shape slides into the fitting portion 34 from below. As shown in Figure 6, when the fitted portion 43 is fitted into the fitting portion 34, the stopper member 40 is attached to the push-down head 30 with the insertion portion 43a positioned inside the internal space 34b and the connecting portion 43b positioned in the opening 34a. At this time, since the fitted portion 43 extends in the tangential direction of the stopper member 40, as shown in Figure 5, the stopper member 40 is supported by the push-down head 30 with its axis facing horizontal and the slit portion 41 facing downward. Therefore, the stopper member 40 supported by the push-down head 30 has a hook shape with a downward opening, so the stopper member 40 can be easily and reliably hooked onto, for example, a handrail or hook installed in a bathroom.

[0037] As shown in Figures 2, 3, and 5, the stopper member 40 can also be configured such that a support flange 44 is integrally provided, protruding radially outward from one circumferential end of the stopper member 40. In the illustrated case, the support flange 44 has a curved recess at its tip that corresponds to the outer circumferential surface of the skirt portion 33.

[0038] As shown in Figure 5, when the fitted portion 43 is fitted into the fitted portion 34 and the stopper member 40 is fixed to the push-down head 30, the support flange 44 comes into contact with the lower end of the skirt portion 33 (or, if a supported projection 33a is provided, the lower end of the skirt portion 33 and the lower surface of the supported projection 33a) and the lower surface of the support projection 13a provided on the support cylinder portion 13. Therefore, for example, when the stopper member 40 is hooked onto a handrail or hook provided in a bathroom and the discharge container 3 using the pump-type discharge device 1 is suspended from the handrail or hook, the support cylinder portion 13 of the mounting cap 10 is supported from below by the support flange 44 via the support projection 13a in addition to the skirt portion 33 of the push-down head 30, thereby preventing the skirt portion 33 and the head body portion 31 (i.e., the push-down head 30) to which the stopper member 40 is fixed from coming off the stem 21 due to the weight of the discharge container 3 and causing the container body 2 to fall.

[0039] As shown in Figures 7-9 as a modified example, the pump-type discharge device 1 may also be configured such that the fitting portion 34 provided on the outer circumferential surface of the skirt portion 33 of the push-down head 30 has a groove-shaped first fitting portion 34A extending in the vertical direction and a groove-shaped second fitting portion 34B extending in the vertical direction, which is provided offset in the circumferential direction from the first fitting portion 34A around the axis O of the stem 21, and the fitted portion 43 provided on the stopper member 40 has a projection-shaped first fitted portion 43A integrally provided on one end of the stopper member 40 in the circumferential direction and a projection-shaped second fitted portion 43B integrally provided on the other end of the stopper member 40 in the circumferential direction.

[0040] In this case, the first fitting portion 34A and the second fitting portion 34B are groove-shaped structures provided inside the stepped portion 35. The first fitting portion 34A has a vertically elongated slit-shaped opening 34A1 and an internal space 34A2 with a circular arc cross-section that is connected to the inside of the opening 34A1, and its cross-sectional shape is L-shaped, with the internal space 34A2 extending circumferentially outward relative to the opening 34A1. Similarly, the second fitting portion 34B has a vertically elongated slit-shaped opening 34B1 and an internal space 34B2 with a circular arc cross-section that is connected to the inside of the opening 34B1, and its cross-sectional shape is L-shaped, with the internal space 34B2 extending circumferentially outward relative to the opening 34B1. The first fitting portion 34A and the second fitting portion 34B are symmetrical in shape with respect to axis O.

[0041] On the other hand, the first fitted portion 43A and the second fitted portion 43B each protrude radially outward from the circumferential end of the stopper member 40 and are projections that extend in the axial direction of the stopper member 40 (along the slit portion 41). The first fitted portion 43A and the second fitted portion 43B each have arc-shaped insertion portions 43A1 and 43B1 corresponding to the internal spaces 34A2 and 34B2 of the first fitted portion 34A and the second fitted portion 34B, and plate-shaped connecting portions 43A2 and 43B2 with a circumferential width corresponding to the openings 34A1 and 34B1 of the first fitted portion 34A and the second fitted portion 34B, and their cross-sectional shape is L-shaped corresponding to the first fitted portion 34A and the second fitted portion 34B.

[0042] In this modified pump-type dispensing device 1, when not in use, such as during distribution, the stopper member 40 can be installed between the mounting cap 10 and the skirt portion 33 of the push-down head 30, as shown in Figure 7, to prevent the push-down head 30 from moving downward and to prevent the liquid from being unexpectedly dispensed.

[0043] On the other hand, as shown in Figures 8 and 9, the stopper member 40 can be attached to the push-down head 30 by removing the stopper member 40 from between the mounting cap 10 and the skirt portion 33 of the push-down head 30, sliding the first fitting portion 43A into the first fitting portion 34A from below, and sliding the second fitting portion 43B into the second fitting portion 34B from below. That is, as shown in Figure 9, the stopper member 40 is attached to the push-down head 30 by arranging the insertion portions 43A1 and 43B1 inside the internal spaces 34A2 and 34B2 respectively, and arranging the connecting portions 43A2 and 43B2 in the openings 34A1 and 34B1. At this time, the first fitting portion 43A and the second fitting portion 43B are each provided at the circumferential end of the stopper member 40, extending along the axis of the stopper member 40. As shown in Figure 8, the stopper member 40 is supported by the push-down head 30 in an annular shape with its axis oriented vertically and the slit portion 41 closed by the skirt portion 33. Therefore, the stopper member 40 supported by the push-down head 30 can be easily and reliably hooked onto, for example, an upward-facing hook or S-hook provided in a bathroom.

[0044] In this modified pump-type discharge device 1, the stopper member 40 can also be configured to integrally provide a first support flange 44A that protrudes radially outward from the lower end of the first fitted portion 43A, and a second support flange 44B that protrudes radially outward from the lower end of the second fitted portion 43B.

[0045] As shown in Figure 8, when the first fitting portion 43A is fitted into the first fitting portion 34A and the second fitting portion 43B is fitted into the second fitting portion 34B, and the stopper member 40 is fixed to the push-down head 30, the first support flange 44A and the second support flange 44B come into contact with the lower end of the skirt portion 33 (or, if a supported projection 33a is provided, the lower end of the skirt portion 33 and the lower surface of the supported projection 33a) and the lower surface of the support projection 13a provided on the support cylinder portion 13, respectively. Therefore, for example, when the stopper member 40 is hooked onto a handrail or hook installed in a bathroom and the discharge container 3 using the pump-type discharge device 1 is suspended from an upward hook or S-hook, the support cylinder portion 13 of the mounting cap 10 is supported from below by the first support flange 44A and the second support flange 44B via the support projection 13a, in addition to the skirt portion 33 of the push-down head 30, thereby preventing the skirt portion 33 and the head body portion 31 (i.e., the push-down head 30) to which the stopper member 40 is fixed from coming off the stem 21 due to the weight of the discharge container 3 and causing the container body 2 to fall.

[0046] As shown in Figures 9 and 10, in this modified pump-type dispensing device 1, a notched groove 45 can be provided on the back surface of the stopper member 40 facing away from the slit portion 41, extending for a predetermined length from one axial end of the stopper member 40 (the lower end in Figure 10) to the other end. In the illustrated case, the notched groove 45 extends with a constant width from one axial end of the stopper member 40 (the lower end in Figure 10) to a position approximately half the axial width of the stopper member 40, and its end is semicircular in shape. The constant width of the notched groove 45 can be, for example, a width that allows an S-shaped hook to be inserted. With this configuration, the dispensing container 3 using the pump-type dispensing device 1 can be easily and reliably suspended from an S-shaped hook by hooking the stopper member 40 attached to the push-down head 30 onto an S-shaped hook at the portion of the notched groove 45.

[0047] The present invention is not limited to the embodiments described above, and can be modified in various ways without departing from its spirit.

[0048] For example, in the above embodiment, the mounting cap 10 has a support cylinder portion 13 and the push-down head 30 has a skirt portion 33, and the stopper member 40 is mounted on the outside of the support cylinder portion 13 between the top wall portion 12 and the skirt portion 33 of the mounting cap 10. However, the configuration is not limited to this, and the skirt portion 33 and the support cylinder portion 13 may not be provided. In this case, the stopper member 40 may be mounted on the stem 21 between the top wall portion 12 of the mounting cap 10 and the head body portion 31 of the push-down head 30.
