In the pump dispenser of Patent Document 1 described above, it is possible to discharge the content liquid at a desired discharge amount by operating the pump head while checking the discharge amount of the content liquid displayed on the display unit. However, adjusting the pushing amount of the pump head each time the pump dispenser is used may cause the user to feel annoyed.

Therefore, there is a demand for a discharge amount adjusting tool capable of easily adjusting the discharge amount of the content liquid and a bottle container having the discharge amount adjusting tool.

In one aspect, it has a bottle body, a pump head, and a neck connected to the pump head, and is attached to a bottle container that discharges the content liquid in the bottle body by pushing down the pump head with respect to the bottle body. A discharge amount adjusting tool for adjusting the discharge amount of the content liquid is provided. The discharge amount adjusting tool includes a plurality of members that are detachably attached to the neck portion so as to be interposed between the bottle body and the pump head. Each of the plurality of members is formed with at least one of a concave portion and a convex portion that fits the concave portion. The plurality of members can be stacked between the bottle body and the pump head in a state where the concave portion and the convex portion are fitted.

The discharge amount adjusting tool according to the above aspect includes a plurality of members that can be stacked between the bottle body and the pump head. Therefore, it is possible to limit the stroke length of the pump head to a desired length by adjusting the number of members attached to the neck portion. Therefore, the discharge amount of the content liquid from the bottle container can be easily adjusted. Further, since the plurality of members are stacked in a state where the concave portion and the convex portion are fitted, the plurality of members can be attached to and detached from the neck portion at once.

In one embodiment, each of the plurality of members has one end and the other end, extending circumferentially around the central axis between one end and the other end, with a neck inside thereof. It is a main body that defines a space for accommodating, and a notch is formed between one end and the other end, and the width of the notch in the width direction perpendicular to the central axis is the outer diameter of the neck.

Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the following description, the same or equivalent elements are designated by the same reference numerals, and duplicate explanations will not be repeated. The dimensional ratios in the drawings do not always match those described.

FIG. 1A is a side view showing a bottle container to which the discharge amount adjusting tool of one embodiment is attached. The bottle container 1 shown in FIG. 1A discharges the content liquid contained therein from the discharge nozzle 14a. Examples of the content liquid contained in the bottle container 1 include, but are not limited to, soapy water, synthetic detergent, cosmetic liquid, disinfectant liquid and the like.

As shown in FIG. 1A, the bottle container 1 includes a bottle body 10 and a pump unit 12. The bottle body 10 is a container for accommodating the content liquid. The pump unit 12 is a mechanism for discharging the content liquid contained in the bottle body 10, and includes a pump head 14, a neck portion 16, and a pump mechanism 18.

The pump head 14 has a discharge nozzle (discharge port) 14a and is provided above the bottle body 10. The neck portion 16 is a tubular body having a cylindrical shape, and the upper end thereof is connected to the pump head 14. The neck portion 16 extends inside the bottle body 10 and its lower end is connected to the pump mechanism 18. The pump mechanism 18 has, for example, a pump chamber, a piston arranged in the pump chamber, a check valve, and the like, and sucks the liquid content of the bottle body 10 into the pump chamber.

The pump head 14 is configured to be movable in the vertical direction. When the pump head 14 is pushed down toward the bottle body 10, the piston of the pump mechanism 18 moves downward, the pressure in the pump chamber rises, and the liquid in the pump chamber is sent to the pump head 14. The content liquid sent to the pump head 14 is discharged from the discharge nozzle 14a. On the other hand, when the pushed-down pump head 14 moves upward, the piston of the pump mechanism 18 moves upward, the pressure in the pump chamber drops, and the liquid content of the bottle body 10 is sucked up into the pump chamber.

As described above, the pump head 14 discharges the content liquid from the discharge nozzle 14a with a discharge amount corresponding to the stroke length (push down amount). That is, the longer the stroke length of the pump head 14, the larger the discharge amount of the content liquid discharged from the discharge nozzle 14a. FIG. 1B shows the maximum stroke length L1 of the bottle container 1 in a state where the discharge amount adjusting tool 20 described later is not attached.

The bottle container 1 further includes a discharge amount adjusting tool 20. The discharge amount adjusting tool 20 is a mechanism for adjusting the discharge amount of the content liquid from the bottle container 1, and is detachably attached to the bottle container 1.

As shown in FIGS. 2 to 4, the discharge amount adjusting tool 20 includes a lower member 22a, intermediate members 22b, 22c, 22d, and an upper member 22e. In the following, when it is not necessary to particularly distinguish the lower member 22a, the intermediate members 22b, 22c, 22d, and the upper member 22e, these may be collectively referred to as a plurality of members 22.

The plurality of members 22 can be detachably attached to the neck portion 16 so as to be interposed between the bottle body 10 and the pump head 14 (see FIG. 7B). By attaching the plurality of members 22 so as to be interposed between the bottle body 10 and the pump head 14, the maximum stroke length of the pump head 14 is reduced, and the discharge amount of the content liquid from the bottle container 1 is limited. To. Further, the plurality of members 22 can be stacked between the bottle body 10 and the pump head 14. Therefore, the maximum stroke length of the pump head 14 can be changed by adjusting the number of the plurality of members 22 attached to the neck portion 16. As a result, the discharge amount of the content liquid from the bottle container 1 can be easily adjusted.

Hereinafter, the details of the plurality of members 22 will be described. The plurality of members 22 are made of, for example, an elastic resin. Specifically, polyethylene or polypropylene is exemplified as the material of the plurality of members 22.

First, among the plurality of members 22, the intermediate members 22b, 22c, 22d will be described. The plurality of intermediate members 22b, 22c, 22d have the same shape as each other. FIG. 5 is a plan view showing the intermediate members 22b, 22c, 22d.

As shown in FIGS. 2 to 5, each of the intermediate members 22b, 22c, and 22d has a main body portion 24, a pair of guide portions 26, and a handle portion 28. As shown in FIG. 5, the main body portion 24 has one end portion 24a and the other end portion 24b, and extends in the circumferential direction around the central axis Z between the one end portion 24a and the other end portion 24b. .. That is, the main body portion 24 extends in a substantially arc shape centered on the central axis Z. In the following description, the direction perpendicular to the central axis Z direction and connecting one end portion 24a and the other end portion 24b is referred to as a width direction, and is a direction perpendicular to the central axis Z direction and the width direction (described later). The direction connecting the notch 30 and the handle 28) is called the front-rear direction.

The main body portion 24 defines a space S in which the neck portion 16 is arranged inside. When the intermediate members 22b, 22c, 22d are attached to the neck portion 16, the neck portion 16 is arranged in the space S in a state where the extending direction thereof coincides with the central axis Z direction. The inner diameter r1 of the main body 24 is slightly larger than the outer diameter r2 of the neck 16. For example, the main body 24 may have an inner diameter of 10 mm to 12 mm.

A notch 30 is formed between one end 24a and the other end 24b of the main body 24. The cutout portion 30 is a portion in which a part of the main body portion 24 is divided. The cutout portion 30 is a gap for passing the neck portion 16 toward the space S side when the intermediate members 22b, 22c, 22d are attached to the neck portion 16. The width W in the width direction of the notch portion 30, that is, the distance between the one end portion 24a and the other end portion 24b is formed to be smaller than the outer diameter r2 of the neck portion 16.

The pair of guide portions 26 are connected to one end portion 24a and the other end portion 24b, respectively. As shown in FIG. 5, each of the pair of guide portions 26 has a pair of inclined surfaces 26s that incline toward each other in the width direction as they move away from the one end portion 24a and the other end portion 24b. That is, the pair of inclined surfaces 26s have a C-shape that expands as the distance from the one end portion 24a and the other end portion 24b is viewed from the central axis Z direction. The angle θ formed by the pair of inclined surfaces 26s can be set to, for example, 60 ° or more and 80 ° or less.

The handle portion 28 is connected to the main body portion 24 at a position opposite to the notch portion 30 in the circumferential direction about the central axis Z. The handle portion 28 is a portion that is gripped by the user when the intermediate member 22c is attached to the neck portion 16, and the tip portion thereof has a bifurcated shape for easy holding.

FIG. 6 shows a cross-sectional view of a plurality of members 22 along the VI-VI line of FIG. As shown in FIG. 6, each of the intermediate members 22b, 22c, and 22d is formed with a concave portion 32 and a convex portion 34 that fits with the concave portion 32. The recess 32 is formed on the upper surface 35 of the intermediate members 22b, 22c, 22d, and is recessed downward (in the Z direction of the central axis) from the upper surface 35. The recess 32 has a substantially rectangular cross-sectional shape and is continuously formed along the upper surface 35 of the main body portion 24, the pair of guide portions 26, and the handle portion 28 (see FIG. 5).

The convex portion 34 is formed on the lower surface 36 of the intermediate members 22b, 22c, 22d, and protrudes downward (in the Z direction of the central axis) from the lower surface 36. The recess 32 is continuously formed along the lower surface 36 of the main body portion 24, the pair of guide portions 26, and the handle portion 28. The convex portion 34 has a substantially rectangular cross-sectional shape that fits into the concave portion 32. The distance d1 from the lower surface 36 of the intermediate members 22b, 22c, 22d to the lower surface of the convex portion 34 is formed to be slightly smaller than the distance d2 from the upper surface 35 of the intermediate members 22b, 22c, 22d to the bottom surface of the recess 32. ing.

The lower member 22a and the upper member 22e are arranged below and above the plurality of intermediate members 22b, 22c, 22d so as to sandwich the plurality of intermediate members 22b, 22c, 22d from the Z-axis direction, respectively. Since the shapes of the lower member 22a and the upper member 22e are similar to the shapes of the plurality of intermediate members 22b, 22c, 22d, the differences from the plurality of intermediate members 22b, 22c, 22d will be mainly described below.

The lower member 22a supports the intermediate members 22b, 22c, 22d. As shown in FIG. 6, a recess 32 is formed on the upper surface 37 of the lower member 22a, but the lower surface 38 of the lower member 22a is a flat surface. That is, the convex portion 34 is not formed on the lower surface 38 of the lower member 22a. The thickness t2 of the lower member 22a (distance between the upper surface 37 and the lower surface 38) may be smaller than the thickness t1 of the intermediate members 22b, 22c, 22d (distance between the upper surface 35 and the lower surface 36). ..

The upper member 22e is arranged above the intermediate members 22b, 22c, 22d. As shown in FIG. 6, the lower surface 40 of the upper member 22e is formed with a convex portion 34 that fits into the concave portions 32 of the plurality of intermediate members 22b, 22c, 22d, but the upper surface 39 of the upper member 22e is flat. It is a face. That is, the concave portion 32 is not formed on the upper surface 39 of the upper member 22e. The thickness t3 of the upper member 22e (distance between the upper surface 39 and the lower surface 40) may be the same as the thickness t1 of the plurality of intermediate members 22b, 22c, 22d.

As described above, at least one of the concave portion 32 and the convex portion 34 is formed in each of the plurality of members 22. Then, the plurality of members 22a to 22e are stacked in a state where the convex portions 34 of the plurality of members 22b to 22e are fitted in the concave portions of the plurality of members 22a to 22d. Since the plurality of members 22 can be removed by releasing the fitting between the concave portion 32 and the convex portion 34, for example, by changing the number of the intermediate members 22b, 22c, 22d, the thickness T of the discharge amount adjusting tool 20 It is possible to adjust.

Next, a method of using the discharge amount adjusting tool 20 will be described with reference to FIGS. 7 (a) and 7 (b). First, as shown in FIG. 7A, a plurality of members 22 are stacked in the Z-axis direction. At this time, the number of the plurality of members 22 to be stacked is changed according to the amount of the content liquid to be discharged from the bottle container 1.

Next, the discharge amount adjusting tool 20 is attached to the neck portion 16 of the bottle container 1. When attaching the discharge amount adjusting tool 20, the pair of inclined surfaces 26s are pressed against the neck portion 16 of the bottle container 1. Then, when the discharge amount adjusting tool 20 is pressed against the neck portion 16 as it is, the pair of inclined surfaces 26s slide against the neck portion 16 and the main body portion 24 is expanded. As a result, the width W of the notch portion 30 is widened, and the neck portion 16 passes through the notch portion 30 and is arranged in the space S of the main body portion 24. In this way, the discharge amount adjusting tool 20 is easily attached to the neck portion 16.

As shown in FIG. 7B, when the discharge amount adjusting tool 20 is attached to the neck portion 16 so as to be interposed between the bottle body 10 and the pump head 14, the maximum stroke length L2 of the pump head 14 is increased. , It is smaller than the maximum stroke length L1 of the bottle container 1 before mounting the plurality of members 22 (see FIG. 1 (b)). Therefore, the amount of the content liquid discharged from the bottle container 1 is limited.

As described above, since the plurality of members 22 can be individually attached to and detached from the neck portion 16, the maximum stroke length L2 of the pump head 14 can be increased by adjusting the number of the plurality of members 22 attached to the neck portion 16. Can be changed. For example, the maximum stroke length L2 of the pump head 14 can be reduced by increasing the number of the plurality of members 22 stacked between the pump head 14 and the bottle body 10. On the contrary, the maximum stroke length L2 of the pump head 14 can be increased by reducing the number of the plurality of members 22 stacked between the pump head 14 and the bottle body 10. Therefore, the discharge amount of the content liquid from the bottle container 1 can be easily adjusted.

In one embodiment, the thickness T of the discharge amount adjusting tool 20 may be set to a thickness substantially equal to the distance between the upper part of the bottle body 10 and the lower part of the pump head 14. In this case, the maximum stroke length L2 of the bottle container 1 can be brought close to 0 by attaching the plurality of members 22a to 22e to the neck portion 16 in a stacked state. As a result, the discharge amount adjusting tool 20 can be used as a stopper for regulating the discharge of the content liquid. By using the discharge amount adjusting tool 20 as a stopper, for example, when the bottle container 1 is put in a bag and carried, it is possible to prevent the content liquid from unintentionally leaking from the bottle container 1.

Further, since the plurality of members 22 are stacked in a state where the concave portion 32 and the convex portion 34 are fitted to each other, the plurality of members 22 can be attached to and detached from the neck portion 16 together. Further, it is possible to prevent the plurality of members 22 from unintentionally falling off from the neck portion 16 during the stroke of the pump head 14.

Although the discharge amount adjusting tool according to various embodiments has been described above, various modifications can be configured without changing the gist of the invention without being limited to the above-described embodiment.

For example, the discharge amount adjusting tool 20 described above includes three intermediate members 22b, 22c, and 22d, but any number of intermediate members can be provided. By increasing the number of intermediate members, the adjustment range of the discharge amount of the content liquid can be expanded.

The dimensions of the plurality of members 22 can be appropriately changed according to the shape of the bottle container 1.
