Description

[Technical Field]

[0001] The present invention relates to a pump container switching adapter that is attached to a pump container equipped with a pump dispenser, a pump dispenser, and a pump container. [Background technology]

[0002] 13(a) and 13(b), various pump containers 50 have been known in which a pump dispenser 51 is attached to a container body 55 containing a liquid such as a cleanser, shampoo, rinse, or cosmetic liquid as the liquid content, and the pump dispenser 51 sucks up and dispenses the liquid. In these pump containers, a predetermined amount of the liquid content is dispensed from a nozzle 54 of the pump head 53 by pressing the pump head 53, which is movable up and down and is attached to the tip of an axial pipe 52 that communicates with a stem constituting the pump mechanism of the pump dispenser 51.

[0003] In addition, in such a pump container 50, the amount of downward movement when the pump head 53 is pressed from its rest state until it can no longer be pressed down is generally defined as the full stroke length, which is the maximum stroke length that can be reached with a single pressing operation, and by pressing the pump head 53 attached to the tip of the axial pipe 52 downward, a desired amount of content liquid corresponding to the full stroke length is ejected from the nozzle portion 54 of the pump head 53.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-298422 Summary of the Invention [Problem to be solved by the invention]

[0005] On the other hand, with conventional pump containers, particularly those for commercial use with large volumes, it may be necessary to switch the stroke length when depressing the pump head to different stroke lengths, such as 25 mL, 10 mL, or 5 mL, to dispense the liquid at different volumes corresponding to each stroke length. Such switching of stroke length has often been achieved by stopping the pump head at a desired position midway through the stroke, rather than pressing the pump head at the full stroke length.

[0006] In response to this, a discharge container (pump container) has been developed that allows the stroke length to be adjusted until the pump head can no longer be depressed, without stopping the pressing operation midway through the stroke, and allows the stroke length to be switched as appropriate, thereby enabling the content liquid to be discharged in a stable manner at a predetermined discharge amount corresponding to each stroke length (see, for example, Patent Document 1).

[0007] According to the pump container of Patent Document 1, one or more discharge volume adjusters are detachably stacked as stopper members on an axial pipe that extends slidably upward from the cap, communicates with the stem of the pump mechanism, and has a pump head attached to its tip.The discharge volume can be adjusted by abutting the lower end of the pump head against the upper end of the stacked stopper members, thereby setting the pressing stroke length.However, as the number of parts required for the discharge volume adjusters is large, there is a need for the development of a technology that makes it easier to switch the stroke length when pressing the pump head, thereby making it possible to easily adjust the discharge volume of the content liquid.

[0008] The present invention relates to a switching adapter for a pump container, a pump dispenser, and a pump container that enable the stroke length when pressing the pump head to be more easily switched, thereby easily adjusting the amount of liquid discharged. [Means for solving the problem]

[0009] The present invention provides a pump container switching adapter for adjusting the discharge rate, which is attached to a pump container equipped with a pump dispenser that discharges liquid contents by pressing a pump head that can move up and down. The adapter has an upright plate portion that can be attached to the neck of the pump container and has a nozzle abutment that regulates the stroke length of the pump head by abutting the nozzle portion of the pump head. The nozzle abutment is located in a circumferential portion of the outer circumferential region of an axial pipe to which the pump head is attached, spaced apart from the axial pipe, and located inside the circumferential path of the tip of the nozzle portion that protrudes laterally from the pump head. The discharge rate can be adjusted by changing the position of the nozzle portion in the circumferential direction around the axial pipe, for example by rotating the head, to change the stroke length of the pump head. The position of the nozzle portion can be changed by selecting a position where the nozzle portion does not interfere with the nozzle abutment and a position where the nozzle portion does not interfere with the nozzle abutment. the nozzle abutment portion and the nozzle portion is the nozzle abutment portion The nozzle position can be changed between a plurality of different positions where the nozzle can contact the nozzle. the nozzle abutment portion and a position that does not interfere with the nozzle abutment portion It is also possible to perform this at two or more positions that can abut against the surface and have different stroke lengths.

[0010] The present invention also provides a mounting cap portion to which a standing plate portion having a nozzle abutment portion is fixed, the nozzle abutment portion abutting against the nozzle portion of the pump head to regulate the stroke length of the pump head, the nozzle abutment portion being disposed in a circumferential portion of an outer peripheral region of an axial pipe to which the pump head is attached, spaced apart from the axial pipe and located inside a circumferential locus of a tip end of the nozzle portion projecting laterally from the pump head, and the position of the nozzle portion in the circumferential direction centered on the axial pipe is changed to a position where the nozzle portion does not interfere with the nozzle abutment portion and a position where the nozzle portion does not interfere with the nozzle abutment portion. the nozzle abutment portion and / or the nozzle portion is the nozzle abutment portionThe pump dispenser is capable of adjusting the discharge amount by switching the stroke length of the pump head among a plurality of different positions at which the pump head can contact the nozzle.

[0011] Furthermore, the present invention provides a pump container that includes the above-mentioned pump dispenser, thereby making it possible to adjust the discharge amount. [Effects of the Invention]

[0012] According to the switching adapter for a pump container, pump dispenser, or pump container of the present invention, the stroke length when pressing the pump head can be more easily switched, making it possible to easily adjust the amount of liquid discharged.

DETAILED DESCRIPTION OF THE INVENTION

[0014] A pump container switching adapter 10 according to a first preferred embodiment of the present invention, shown in Figure 1, is used as a pump container 17 equipped with a pump dispenser 16, preferably detachably attached to a neck 17b of a container body 17a of a bottle-shaped container for storing a commercial detergent. Commercial detergents are preferably used undiluted or diluted with water to a predetermined concentration (e.g., undiluted to 200-fold dilution). In this first embodiment, the pump container switching adapter 10 is attached to the neck 17b of the container body 17a so that diluted solutions of different predetermined concentrations can be obtained stably and accurately. This makes it easier to change the stroke length when pressing the pump head 16a of the pump dispenser 16, allowing the content liquid to be easily and stably dispensed at a predetermined, adjusted amount.

[0015] As shown in Figures 1 and 2(a) and (b), the switching adapter 10 for a pump container of this first embodiment is an adapter that is attached to a pump container 17 equipped with a pump dispenser 16 that discharges the contents by pressing a pump head 16a that can move up and down, and allows the discharge volume to be adjusted.It can be attached to the neck portion 17b of the pump container 17, and has an upright plate portion 11 with a locking notch portion 12 on which a nozzle abutment portion 14a is provided, which regulates the stroke of the pump head 16a by abutting preferably the upper side of the nozzle portion 16b of the pump head 16a (see Figures 4(a) and 5(a)). The upper nozzle abutment portion 14a provided on the upright plate portion 11 is positioned in a circumferential portion of the outer peripheral region of the axial pipe 16c (see Figure 2(b)) to the tip of which the pump head 16a is attached, spaced apart from the axial pipe 16c and inside the circumferential path of the tip of the nozzle portion 16b protruding laterally from the pump head 16a (see Figures 4(a) and 5(a)). The discharge volume can be adjusted by changing the position of the nozzle portion 16b of the pump head 16a in the circumferential direction centered on the axial pipe 16c, i.e., the orientation of the nozzle portion 16b, and switching the stroke length of the pump head 16a between a position where the nozzle portion 16b does not interfere with the nozzle abutment portion 14a (see Figures 3(a) and (b)) and a position where the nozzle portion 16b can abut against the nozzle abutment portion 14a (see Figures 4(a), (b), and 5(a) and (b)), and / or between a plurality of different positions where the nozzle portion 16b can abut against the upper nozzle abutment portion 14a (see Figures 4(a), (b), and 5(a) and (b)).

[0016] Here, the term "nozzle," or nozzle portion 16b, as used herein refers to a portion that protrudes from pump head 16a laterally relative to the direction in which pump head 16a is operated for discharging, moves integrally with pump head 16a, and through which liquid passes when it is discharged. Preferably, a discharge port is provided at the end opposite pump head 16a. This includes not only the flow path through which liquid passes when it is discharged, but also the surrounding area. In some cases, pump head 16a and nozzle portion 16b are preferably molded as a single unit.

[0017] In addition, in the pump container switching adapter 10 of the first embodiment, the upright plate portion 11 preferably has an arc-shaped curved shape along the circumferential direction centered on the axial pipe 16c when viewed from above.

[0018] Furthermore, the pump container switching adapter 10 of the first embodiment is provided with a protruding base end plate portion 13 that preferably bends and protrudes from the base end portion of the standing plate portion 11 for mounting the pump container switching adapter 10 to the pump container 17, and this protruding base end plate portion 13 has a mounting opening 13a with an inner diameter slightly larger than the outer diameter of the neck portion 17b of the container body 17a of the pump container 17. By sandwiching the opening edge of this mounting opening 13a between the outer periphery of the base end of the neck portion 17b of the container body 17a and the mounting cap portion 16d of the pump dispenser 16, the pump container switching adapter 10 is mounted and fixed to the pump container 17 with the standing plate portion 11 arranged upright along the axial pipe 16c.

[0019] Furthermore, in the pump container switching adapter 10 of the first embodiment, the locking notch 12 provided with the nozzle abutment 14a against which the upper side of the nozzle 16b of the pump head 16a abuts consists of a U-shaped notch 14 formed by cutting the side edge of the standing plate 11 into a U-shape, and the upper side of the nozzle 16b abuts against the nozzle abutment 14a, which is the upper edge of this U-shaped notch 14. The U-shaped notches 14 are preferably formed on both side edges of the standing plate 11, with the upper nozzle abutment 14a, which is the upper edge, being at different height positions.

[0020] In the first embodiment, the pump container 17 includes a pump container body 17a, to which the pump container switching adapter 10 is attached, which is a blow-molded product made of a synthetic resin, such as high-density polyethylene, low-density polyethylene, or polypropylene. The pump container body 17a contains a commercial cleaning agent as a liquid agent, and a cylindrical neck portion 17b is provided at its upper end when the pump container is placed on a support surface, through which the liquid agent can be dispensed. A male thread ridge is formed on the outer periphery of the neck portion 17b, and the pump dispenser 16 is attached integrally to the container body 17a by threading the attachment cap portion 16d onto the neck portion 17b. As described above, the pump container switching adapter 10 is attached to the pump container 17 by sandwiching the protruding base end plate portion 13 between the outer periphery of the base end of the neck portion 17b and the attachment cap portion 16d of the pump dispenser 16.

[0021] The pump dispenser 16 has a known configuration including a pump housing 16e (see FIG. 2(a)) with a pump mechanism installed therein, an axial pipe 16c communicating with the stem of the pump mechanism, a pump head 16a with a nozzle portion 16b protruding laterally and integrally attached to the tip of the axial pipe 16c, an attachment cap portion 16d, a suction pipe 16f, etc. The liquid agent taken into a pump chamber inside the pump housing 16e via the suction pipe 16f can be delivered to the axial pipe 16c via the stem by sliding the piston of the pump mechanism. The delivered liquid agent is discharged from the nozzle portion 16b of the pump head 16a communicating with the axial pipe 16c at a predetermined discharge amount corresponding to the stroke length.

[0022] In the first embodiment, the pump mechanism of the pump dispenser 16 is preferably not provided with a spring or other biasing means for biasing the piston upward, but rather is of a so-called pump return springless type in which the axial pipe 16c and the pump head 16a at the tip thereof are manually pulled upward, and then the pump head 16a is pressed downward to discharge the liquid. This allows the pump head 16a to remain pressed downward when the pump container 17 is not in use and does not need to discharge the liquid, thereby preventing the pump container 17 from becoming bulky when not in use. In the first embodiment, the pump mechanism of the pump dispenser 16 may also be of a so-called pump return spring type in which a spring or other biasing means for biasing the piston upward is provided.

[0023] The pump container switching adapter 10 of the first embodiment is an injection-molded product made of synthetic resin, such as ABS resin, polyacetal resin, or polypropylene. As described above, the pump container switching adapter 10 includes an upright plate portion 11 and an overhanging base end plate portion 13, which preferably extends from the base end of the upright plate portion 11 in a bent manner. In the first embodiment, the overhanging base end plate portion 13 is an annular plate portion having a circular mounting opening 13a and an inner diameter slightly larger than the outer diameter of the neck portion 17b of the container body 17a. The upright plate portion 11 is provided on the outer peripheral edge of the annular overhanging base end plate portion 13, extending from a portion of the outer peripheral edge, for example, at an angle of approximately 120° in the circumferential direction. A reinforcing edging rib wall 13b is provided in a continuous upright manner in the area other than the area where the upright plate portion 11 extends.

[0024] As described above, the pump container switching adapter 10 is attached and fixed to the pump container 17 by preferably sandwiching the opening edge of the mounting opening 13a of the protruding base end plate portion 13 between the outer periphery of the base end of the neck portion 17b of the container body 17a and the mounting cap portion 16d of the pump dispenser 16, and the upright plate portion 11 is arranged upright along the axial pipe 16c, spaced apart from the axial pipe 16c.

[0025] In the first embodiment, the upright plate portion 11 of the pump container switching adapter 10 stands upright from the outer peripheral edge of the annular overhanging base end plate portion 13, and preferably has a shape that curves in an arc in the circumferential direction centered on the axial pipe 16c when viewed from above. The upright plate portion 11 is preferably formed to have a rectangular front shape and is formed to a height h (see FIG. 1 ) of, for example, about 70 to 160 mm from the overhanging base end plate portion 13. Furthermore, U-shaped notches 14, cut into a U-shape and provided as locking notches 12, are preferably provided on both side edges of the upright plate portion 11. These U-shaped notches 14 on both sides are formed with the upper edge portions 14a, which are the upper abutment portions, at different height positions.

[0026] That is, the pair of U-shaped notches 14 formed on both side edges of the standing plate portion 11 are formed with the height positions of the respective upper edge portions 14a, which are the upper nozzle abutment portions, being different, so that by abutting the upper side of the nozzle portion 16b against the inside of each nozzle abutment portion 14a (see Figures 4(a) and 5(a)), and then pressing the pump head 16a (see Figures 4(b) and 5(b)), the stroke length of the pump head 16a can be easily regulated and set to different predetermined lengths.

[0027] In the pump container switching adapter 10 of this first embodiment having the above-mentioned configuration, and the pump container 17 having the pump dispenser 16 to which the pump container switching adapter 10 is attached, the position of the pump head 16a of the pump dispenser 16, which is rotatably attached to the neck portion 17b of the container body 17a, can be adjusted by appropriately rotating it, and as shown in Figures 3(a) and (b), by pressing the pump head 16a with the nozzle portion 16b not interfering with the upright plate portion 11, it is possible to press the pump head 16a at its full stroke length and eject a predetermined amount of liquid, such as 25 mL. Furthermore, by adjusting the position of the pump head 16a and pressing the upper surface of the nozzle portion 16b, whose tip protrudes outward beyond the standing plate portion 11, against the inside of the upper nozzle contact portion 14a, which is the upper edge of each of the U-shaped notches 14 on both sides that form the locking notch 12, as shown in Figures 4(a) and 4(b) and 5(a) and 5(b), it becomes possible to press the pump head 16a at a regulated, predetermined stroke length and eject a set amount of liquid, such as 10 mL or 5 mL.

[0028] In this embodiment, the nozzle portion 16b can be switched between 25 mL at a full stroke when it is in a position where it does not interfere with the nozzle contact portion 14a and 10 mL or 5 mL when it is in a position where it can contact the nozzle contact portion 14a. It is also possible to not use any of these three different discharge volumes when it is in a position where it does not interfere with the nozzle contact portion 14a, in which case the discharge volume can be switched between 10 mL and 5 mL between the positions where it can contact the two nozzle contact portions 14a. It is preferable that the upper side 14a of the U-shaped cutout 14 has the same length because the upper side of the nozzle portion 16b must abut against it when the pump head 16a is at the same position in the rotational direction.

[0029] Therefore, according to the pump container switching adapter 10 and pump container 17 of this first embodiment, the position of the pump head 16a in the circumferential direction centered on the axial pipe 16c can be adjusted to switch the stroke length between the stroke of the pump head 16a when it is pressed without interfering with the upright plate portion 11, and the stroke when the pump head 16a is pressed with the upper side of the nozzle portion 16b abutting against the upper edge portion 14a of the locking notch portion 12, making it possible to more easily switch the stroke length when pressing the pump head 16a and easily adjust the amount of liquid discharged.

[0030] In this embodiment, the nozzle portion 16b abuts against the nozzle abutment portion 14a, which is the upper edge portion of the U-shaped cutout portion 14, but does not abut against the lower edge portion 14b. However, by increasing the height of the lower edge portion 14b, the nozzle portion 16b can be made to abut not only the upper edge portion but also the lower edge portion, thereby adjusting the stroke length.

[0031] 6(a) to 6(f) illustrate other configurations of the pump container switching adapter 10 of the first embodiment. In the pump container switching adapter 10 shown in Fig. 6(a) to 6(d), the U-shaped notch 14', which is the locking notch 12, is formed by cutting into only one side edge of the standing plate portion 11 in a U-shape.

[0032] In addition, in the pump container switching adapter 10 shown in Fig. 6(a), an inclined portion 14c' that slopes downward from the open side of the U-shape toward the back is provided on the inside of the upper nozzle abutment portion 14a' that is the upper side of the U-shaped cutout 14'. In the pump container switching adapter 10 shown in Fig. 6(b), one or more stepped portions 14d' that gradually narrow the opening width from the open side of the U-shape toward the back are provided on the inside of the upper nozzle abutment portion 14a' that is the upper side of the U-shaped cutout 14'.

[0033] The pump container switching adapter 10 shown in Figures 6(a) and 6(b) also makes it possible to adjust the position of the pump head 16a in the circumferential direction centered on the axial pipe 16c, and then press the pump head 16a while the upper side of the nozzle portion 16b is abutted against a predetermined position inside the inclined portion 14c' or stepped portion 14d' provided as the upper nozzle abutment portion 14a' on each upper side portion 14a', thereby easily restricting and setting the stroke length of the pump head 16a to the lower end of the pump to different predetermined lengths, thereby achieving the same effects as the pump container switching adapter 10 described above and shown in Figures 1 to 5.

[0034] Furthermore, in the pump container switching adapter 10 shown in Fig. 6(c), a guide mark 14f' is provided on the outer peripheral surface of the upper part of the U-shaped cutout 14' on the upright plate portion 11 opposite the axial pipe 16f, the guide mark 14f' indicating the amount of liquid discharged corresponding to the stroke length when the nozzle portion 16b of the pump head 16a is pressed with the upper side of the nozzle portion 16b of the pump head 16a abutting and engaging at the corresponding position. In the pump container switching adapter 10 shown in Fig. 6(d), a guide mark 14g' is provided on the upper edge above the U-shaped cutout 14' on the upright plate portion 11, extending opposite the axial pipe 16f. This guide mark 14f' indicates the amount of liquid discharged corresponding to the stroke length when the nozzle portion 16b of the pump head 16a is pressed with the upper side of the nozzle portion 16b of the pump head 16a abutting and engaging at the corresponding position.

[0035] Here, the guide display 14f' may be the amount of liquid to be discharged when the pump head 16a is pressed at the corresponding position, or the dilution rate when diluting the predetermined amount of liquid that has been discharged. The guide display may include not only numbers and units but also scales, letters, symbols, etc.

[0036] The pump container switching adapter 10 shown in Figures 6(c) and 6(d) also achieves the same effects as the pump container switching adapter 10 shown in Figures 1 to 5 described above, and in addition, the outer peripheral surface of the upper part of the standing plate portion 11 and the indicator rib 14g' are provided with a guide mark 14f' that serves as a guide for the discharge amount of the liquid agent, which is an internal liquid, making it possible to select the discharge amount required for different dilution concentrations of the liquid agent depending on the application.

[0037] Furthermore, in the pump container switching adapter 10 shown in Figure 6(e), the locking notch 12 that abuts and locks against the upper surface of the nozzle portion 16b of the pump head 16a consists of a pair of inner U-shaped cutouts 14" formed by cutting the inner side edges 14i" on both sides of a band-shaped cutout 14h" formed by cutting downward from the circumferential center of the upper edge of the upright plate portion 11, and further cutting into a U-shape with the inner side edges 14i" at different heights of the upper edge, so that the upper side of the nozzle portion 16b abuts against the inside of the upper nozzle abutment portion 14a" which is the upper edge of each inner U-shaped cutout 14". In addition, a convex piece 14j" protruding downward is provided at the open end of the upper nozzle abutment portion 14a" which is the upper edge of the U-shape of the inner U-shaped cutout 14" to prevent the nozzle portion 16b abutting and locking against the upper edge portion 14a".

[0038] With the pump container switching adapter 10 shown in Figure 6(e), it is also possible to press the pump head 16a to the bottom end of the pump from a state in which the nozzle portion 16b is in contact with and engaged inside the upper nozzle abutment portion 14a", which is the upper edge portion of each of a pair of inner U-shaped cutouts 14", which are formed by cutting in a U-shape from the band-shaped cutout portion 14h", achieving the same effect as the pump container switching adapter 10 described above and shown in Figures 1 to 5. Furthermore, since a protruding piece 14j" for preventing disengagement is provided downwardly at the open end of the upper nozzle abutment portion 14a", which is the upper edge portion of the inner U-shaped cutout portion 14", it is possible to effectively prevent the nozzle portion 16b from shifting sideways and jumping up to the top end due to an impact or the like in a pump container 17 equipped with a pump dispenser 16 of the so-called pump return spring type. The protrusions 14j, 14j' for preventing removal can also be provided at the open end of the upper nozzle abutment portion 14a, which is the upper edge of the U-shaped cutout portion 14 in the above-mentioned pump container switching adapter 10 shown in Figures 1 to 5, or at the open end of the upper nozzle abutment portion 14a', which is the upper edge of the U-shaped cutout portion 14' in the pump container switching adapter 10 shown in Figures 6(a) to (d) (see Figure 6(f)).

[0039] FIG. 7 illustrates a pump container switching adapter 20 according to a second preferred embodiment of the present invention. While the pump container switching adapter 10 of the first embodiment includes the locking notch 12 that engages with the upper surface of the nozzle portion 16b of the pump head 16a to restrict the stroke of the pump head 16a, the pump container switching adapter 20 of the second embodiment includes a locking notch 22 that engages with the lower surface of the nozzle portion 16b of the pump head 16a to restrict the stroke of the pump head 16a. Regarding the pump container switching adapter 20 of the second embodiment, differences from the pump container switching adapter 10 of the first embodiment will be mainly described, and similar components will be designated by the same reference numerals and will not be described again. For components not specifically mentioned, the description of the pump container switching adapter 10 of the first embodiment applies as appropriate.

[0040] 7 and 8(a) and (b), a pump container switching adapter 20 of the second embodiment is an adapter for adjusting the discharge rate when attached to a pump container 17 having a pump dispenser 16 that discharges liquid contents by pressing a pump head 16a that is movable up and down. The adapter is attachable to the neck portion 17b of the pump container 17 and has an upright plate portion 21 with a locking notch 22 that serves as a nozzle abutment and that abuts against, preferably the lower surface of, the nozzle portion 16b of the pump head 16a to regulate the stroke of the pump head 16a (see FIGS. 9(b) and 10(b)). The locking notch 22 that serves as a nozzle abutment provided on the upright plate portion 21 is located in a circumferential portion of the outer circumferential region of the axial pipe 16c to the tip of which the pump head 16a is attached, spaced apart from the axial pipe 16c, and located inside the circumferential path of the tip of the nozzle portion 16b that protrudes laterally from the pump head 16a. The position of the nozzle portion 16b of the pump head 16a in the circumferential direction around the axial pipe 16c, i.e., the orientation of the nozzle portion 16b, is changed between a position where the nozzle portion 16b does not interfere with the locking notch portion 22 which is the nozzle abutment portion (see Figures 8(a) and (b)) and a position where the nozzle portion 16b can abut against the locking notch portion 22 which is the nozzle abutment portion (see Figures 9(a) and (b) and Figures 10(a) and (b)), and / or Nozzle contact part The discharge amount can be adjusted by switching the stroke length of the pump head 16a between a plurality of different positions where the pump head 16a can abut against the locking notch 22.

[0041] In addition, in the pump container switching adapter 20 of the second embodiment, the upright plate portion 21 preferably has an arc-shaped curved shape along the circumferential direction centered on the axial pipe 16c when viewed from above.

[0042] Furthermore, the pump container switching adapter 20 of the second embodiment is provided with a protruding base end plate portion 23 that preferably bends and protrudes from the base end portion of the standing plate portion 21 for mounting the pump container switching adapter 20 to the pump container 17, and this protruding base end plate portion 23 has a mounting opening 23a with an inner diameter slightly larger than the outer diameter of the neck portion 17b of the container body 17a of the pump container 17. By sandwiching the opening edge of this mounting opening 23a between the outer periphery of the base end of the neck portion 17b of the container body 17a and the mounting cap portion 16d of the pump dispenser 16, the pump container switching adapter 20 is mounted and fixed to the pump container 17 with the standing plate portion 21 arranged upright along the axial pipe 16c.

[0043] Furthermore, in the pump container switching adapter 20 of the second embodiment, the locking notch 22, which is preferably a nozzle abutment portion that abuts and locks against the underside of the nozzle 16b of the pump head 16a, is composed of an inclined cutout 24 formed by cutting the upper edge of the standing plate portion at an angle, and the lower surface of the lower side of the nozzle 16b abuts and locks against a predetermined position in the inclined cutout 24. In the second embodiment, the inclined cutout 24 is preferably provided with one or more steps 24b whose height gradually decreases from one side to the other of the upper edge of the standing plate portion 21.

[0044] Furthermore, in the second embodiment, the pump dispenser 16 is preferably of a so-called pump return spring type in which the pump mechanism inside the pump housing 16e is preferably provided with a biasing means such as a spring that biases the piston upward. In the second embodiment, the pump dispenser 16 may be of a so-called pump return springless type in which the pump mechanism does not include a biasing means such as a spring that biases the piston upward, and the pump head 16a is pressed downward to discharge the liquid agent after the axial pipe 16c and the pump head 16a at the tip of the axial pipe 16c are manually pulled upward.

[0045] Like the pump container switching adapter 10 of the first embodiment, the pump container switching adapter 20 of the second embodiment is an injection-molded product made of a synthetic resin, such as ABS resin, polyacetal resin, or polypropylene. As described above, the pump container switching adapter 20 includes an upright plate portion 21 and an overhanging base end plate portion 23, which preferably extends in a bent manner from the base end of the upright plate portion 21. In the second embodiment, the overhanging base end plate portion 23 is an annular plate portion having a circular mounting opening 23a and an inner diameter slightly larger than the outer diameter of the neck portion 17b of the container body 17a. The upright plate portion 21 is provided on the outer peripheral edge of the annular overhanging base end plate portion 23, extending from a portion of the outer peripheral edge, for example, at an angle of approximately 120° in the circumferential direction. A reinforcing edging rib wall 23b is provided in a continuous upright manner in the area other than the area where the upright plate portion 21 extends.

[0046] Furthermore, as described above, the switching adapter 20 for the pump container of this second embodiment is attached and fixed to the pump container 17 by sandwiching the opening edge of the mounting opening 23a of the protruding base end plate portion 23 between the outer periphery of the base end of the neck portion 17b of the container body 17a and the mounting cap portion 16d of the pump dispenser 16, and the upright plate portion 21 is arranged upright along the axial pipe 16c, away from the axial pipe 16c.

[0047] In the second embodiment, the upright plate portion 21 of the pump container switching adapter 20 stands upright from the outer peripheral edge of the annular overhanging base end plate portion 23, and preferably has a shape that curves in an arc in the circumferential direction centered on the axial pipe 16c when viewed from above. The upright plate portion 21 is preferably formed to have a frontal shape of a right-angled trapezoid laid on its side, and is formed to have a height h' (see FIG. 7) of, for example, about 65 to 130 mm from the overhanging base end plate portion 23. The upper side of the laid-down right-angled trapezoid forms an inclined cutout portion 24, and this inclined cutout portion 24 has, for example, four step portions 24b whose height gradually decreases from one side to the other of the upper side defined by the inclined cutout portion 24 of the upright plate portion 21.

[0048] The inclined cutout 24 of the upright plate portion 21 forms steps 24b whose height gradually decreases from one side to the other of the upper edge portion (locking notch) 22, which is the nozzle abutment portion.This makes it possible to easily regulate and adjust the stroke length of the pump head 16a so that it becomes different predetermined lengths by pressing the pump head 16a from a state in which the pump head 16a is positioned at the top (see Figures 9(a) and 10(a)), preferably by using a biasing means, until the lower side of the nozzle portion 16b abuts against each of the steps 24b (see Figures 9(b) and 10(b)).

[0049] In the pump container 17 having the pump dispenser 16 attached to the pump container switching adapter 20 of the second embodiment having the above-described configuration and the pump head 16a of the pump dispenser 16 rotatably attached to the neck portion 17b of the container body 17a, the position can be adjusted by appropriately rotating the pump head 16a, and by pressing the nozzle portion 16b without interfering with the upright plate portion 11 as shown in Figures 8(a) and (b), the pump head 16a can be pressed at its full stroke length to eject a predetermined amount of liquid, such as 25 mL. Furthermore, by adjusting the position of the pump head 16a, as shown in Figures 9(a) and (b) and Figures 10(a) and (b), the pump head 16a can be pressed at a regulated, predetermined stroke length until the underside of the nozzle portion 16b, whose tip protrudes outward beyond the upright plate portion 11, abuts against each of the step portions 24b of the inclined cut portion 24, which is the locking notch portion 22 serving as the nozzle abutment portion, thereby making it possible to eject a set, predetermined amount of liquid, such as 20 mL or 5 mL.

[0050] Therefore, according to the pump container switching adapter 20 and pump container 17 of this second embodiment, the position of the pump head 16a in the circumferential direction centered on the axial pipe 16c can be adjusted to switch the stroke length between the stroke of the pump head 16a when it is pressed without interfering with the upright plate portion 11, and the stroke when the pump head 16a is pressed from a state in which the underside of the nozzle portion 16b can abut against the locking notch portion 12, making it possible to more easily switch the stroke length when pressing the pump head 16a and easily adjust the amount of liquid discharged.

[0051] 11(a) and 11(b) illustrate another example of the pump container switching adapter 20 of the second embodiment. In the pump container switching adapter 20 shown in FIG. 11(a), the locking notch (nozzle contact portion) 22 formed by the inclined cutout 24 obliquely cut into the upper edge of the upright plate portion 21 does not have a step 24b and remains inclined. The pump container switching adapter 20 shown in FIG. 11(a) also allows the stroke length of the pump head 16a to be easily regulated and adjusted to different predetermined lengths by adjusting the position of the pump head 16a in the circumferential direction around the axial pipe 16c and abutting the lower surface of the nozzle portion 16b against a predetermined position on the inclined cutout 24. This provides the same advantageous effects as the pump container switching adapter 20 shown in FIGS. 7 to 10.

[0052] In the pump container switching adapter 20 shown in Figure 11(b), a guide mark 24f' is provided on the outer peripheral surface of the upper end portion of the upright plate portion 21 opposite the axial pipe 16f, which guides the amount of liquid discharged according to the stroke length when the nozzle portion 16b of the pump head 16a is pressed in a state in which the upper surface of the nozzle portion 16b is abutted and engaged against the corresponding portion. This makes it possible to select the discharge amount required for different dilution concentrations of liquid for different applications, just like the pump container switching adapter 10 shown in Figures 6(c) and 6(d).

[0053] 12(a) to 12(d), the use of an integrated cover 30 enables the pump container switching adapters 10 and 20 to be more stably attached as a single unit to a pump container including a pump dispenser 16. Specifically, the integrated cover 30 includes an annular pressing plate portion 31 having an inner diameter slightly larger than the outer diameter of the pump housing 16e of the pump dispenser 16 and a plate width sufficient to press against the shoulder of the mounting cap portion 16d of the pump dispenser 16, the annular pressing plate portion 31 including a notch 31a for passing the axial pipe 16c, and three upright locking legs 32 extending vertically downward from the edge of the annular pressing plate 31 and positioned on both sides of the notch 31a and facing the notch 31a. A fixing claw 32a, preferably having a right-angled triangular cross section, is formed at the lower end of each upright locking leg portion 32 so as to protrude inward.

[0054] On the other hand, preferably, the protruding base end plate portion 13, 23 of the pump container switching adapter 10, 20 has engagement holes 33 formed in three locations at positions corresponding to the upright locking leg portion 32 of the integrated cover 30 at the connection corner portion with the upright plate portion 11, 21 that stands up from the outer peripheral edge portion and the edging rib wall 13b, 23b.

[0055] For example, by clamping the opening edge of the mounting opening 13a, 23a of the protruding base end plate portion 13, 23 between the outer periphery of the base end of the neck portion 17b of the container body 17a and the mounting cap portion 16d of the pump dispenser 16, the pump container switching adapter 10, 20 is attached to the pump container (see Figure 12(a)), and the integrated cover 30 is passed through the axial pipe 16c through the cutout 31a and pressed downward so that the annular pressing plate portion 31 overlaps the shoulder portion of the mounting cap portion 16d, and the fixing claws 32a of each upright locking leg portion 32 are forcibly pressed to engage with the three engagement holes 33 (see Figures 12(c) and (d)). As a result, the mounting cap portion 16d is firmly pressed against the protruding base end plate portion 13, 23 via the integrated cover 30, so that the pump container switching adapter 10, 20 clamped by the mounting cap portion 16d is attached to the pump container equipped with the pump dispenser 16 in a more stable state (see Figure 12(b)).

[0056] The present invention is not limited to the above-described embodiments and various modifications are possible. For example, by directly mounting a standing plate having a locking notch on the mounting cap of a pump dispenser, rather than via the pump container switching adapter, it is possible to obtain the same effects as a pump dispenser in which a standing plate is mounted via a pump container switching adapter having a protruding base end plate. Furthermore, by using a pump dispenser in which a standing plate is mounted directly on the mounting cap, it is possible to obtain the same effects as a pump container in which a standing plate is mounted via a pump container switching adapter having a protruding base end plate.
