The first hanging tube portion 60 is inserted into the guide tube 24 .
However, these structures can be changed as appropriate.

A pair of operating pieces 44 are formed on the lower half cylindrical portion 42a so as to be positioned outside the operated portion 6. As shown in FIG. One of the pair of operation pieces 44 may be omitted.
In the illustrated example, these operation pieces 44 are formed so as to face a portion from the lower end to the vicinity of the upper end of the operated portion 6 as shown in FIG.
As shown in FIG. 4, each operation piece 44 is formed by making an inverted U-shaped cutout 46 in the lower half cylindrical portion 42a.
The inverted U-shaped notch 46 is a single continuous through groove that cuts the upper and circumferential sides of the operating piece, and the operating piece 44 surrounded by this notch can be pushed inward. possible to form. The term "inverted U-shape" means a shape that allows the pushing operation, and includes, for example, a U-shape rotated by 90° and an inverted V-shape.
In the illustrated example, the lower end of each operating piece 44 is connected to the lower half cylindrical portion 42a by a hinge 48 formed between the lower ends of the cut 46. As shown in FIG.
Note that these structures can be changed as appropriate.
A pressing end portion 44 a is formed at the upper end portion of the operating piece 44 .
This pushing end 44a has a role of pushing up the bottle 2. As shown in FIG.
As shown in FIG. 5, by pushing the operating piece 44 inward, the pressing end 44a moves along an arc C centered on the hinge 48. This is achieved by sliding along the slide surface portion S of the portion 6 and rubbing it.
The radius R of the arc C corresponds to the vertical length of the operating piece 44. The longer the radius, the easier it is to push the pressing end 44a of the operating piece 44 inward.
Therefore, in this embodiment, the operated portion 6 is provided in the range from the upper end to the lower portion of the body portion 4 of the bottle 2, and the operating piece 44 is formed vertically corresponding to the shape of the operated portion 6. ing.
Further, in the illustrated example, as shown in FIG. 4, the operation piece 44 is formed in a vertically long substantially rectangular shape. The upper side of this rectangle is recessed so that the central portion is slightly lower than both ends of the upper side, and the central portion is used as the pressing end portion 44a.
The reason why the upper side of the rectangle is shaped as described above is to match the shape of the slide surface portion S curved in the circumferential direction. With such a structure, the upper edge of the operation piece 44 slides on the slide surface portion S over a wide range in the circumferential direction, and the bottle 2 can be pushed up in a stable posture.
However, these structures can be changed as appropriate.

A locking groove 50 is formed at an appropriate portion of the lower half cylindrical portion 42a (lower end portion on the front side in the illustrated example). The engaging protrusion 14 is inserted into the locking groove 50 .
In the illustrated example, a pair of locking grooves 50 positioned in the diametrical direction of the cover cylinder 44 are formed corresponding to the engaging protrusions 14, but the structure can be changed as appropriate.
In the illustrated example, as shown in FIG. 1, the lower end of the lock groove 50 is opened by aligning the lower end of the cover cylinder 42 with the lower end of the lock groove 50 . Therefore, the engaging projection 14 can be inserted into the locking groove 50 from this open end.
The locking groove 50 has a locking groove portion 50a and an elevating groove portion 50b.
The lock groove portion 50a and the lifting groove portion 50b are adjacent to each other in the circumferential direction. Therefore, by pressing the engaging protrusion 14 in the circumferential direction, the bottle 2 rotates with respect to the cover member 40, and the engaging protrusion 14 can move between the two grooves.
The locking groove 50 in the illustrated example is formed in a substantially L shape that continues from the low-height locking groove portion 50a to the high-height lifting groove portion 50b.
The height of the locking groove portion 50a is formed to be equal to the vertical width of the engaging protrusion 14, as shown in FIG. Therefore, even if the operating piece 44 is pushed inward while the engaging projection 14 is in the locking groove 50a, the bottle 2 cannot be pushed up.
The width of the lifting groove 50b is approximately the same as the width of the engaging protrusion 14, as shown in FIGS.
It is desirable that the gap G between the upper ends of the lifting groove portion 50b and the locking groove portion 50a is equal to or greater than the stroke length of the stem 30 of the discharger 20. As shown in FIG.
A stopper 52 protrudes downward from the upper edge of the lock groove 50a at a position where the lock groove 50a is connected to the lift groove 50b.
The projection length of the stopper 52 is such that when the cover cylinder 42 is rotated with respect to the bottle 2, the engaging projection 14 overcomes the stopper and enters the lifting groove 50b from the lock groove 50a. is as small as possible.

The nozzle 64 is integrally connected to the upper end of the cover cylinder 42 . However, this structure can be changed as appropriate, and the nozzle 64 and the cover tube 42 may be formed separately.
The illustrated nozzle 64 has a tapered cylindrical peripheral wall 65 with a small diameter at the tip rising from the inner edge of the inward flange 58 . A hemispherical apex 66 is formed at the upper end of the cylinder peripheral wall 65, and an injection port 68 is opened in the center of the apex 66. As shown in FIG.
Furthermore, a connecting cylinder portion 70 is suspended from the top portion 66 so as to surround the injection port 68 .
The connecting tube portion 70 is fitted and fixed to the outer surface of the stem 30 in a liquid-tight manner.
However, these structures can be changed as appropriate.

The rod-like member 72 is a member arranged inside the connecting tube portion 70 . This rod-shaped member 72 has a large-diameter head 76 attached to the upper end of an elongated vertical rod portion 74 fitted and fixed in the upper portion of the connecting cylinder portion 70 .
A spin channel P is formed around the head 76, and the liquid discharged from the stem 30 passes between the vertical rod portion 74 and the connecting tube portion 70, and passes through the spin channel P. It is formed so that it is sprayed from the injection port 68.
However, unlike the illustrated example, the structure may be such that the contents are discharged without being sprayed.

A cap 80 is detachably fitted to the outside of the nozzle 64 .

In the state shown in FIG. 3, since the engaging projection 14 is positioned within the locking groove 50a, even if the pair of operating pieces 44 is pushed, the bottle 2 cannot be pushed up.
2 from the state shown in FIG. 3, the bottle 2 rotates with respect to the cover member 40, and the engaging projection 14 climbs over the stopper 52, As shown in FIG. 1, it moves into the raising/lowering groove portion 50b.
1, the cap 80 is removed, the cover member is gripped with one hand by placing one's fingers on the outer surfaces of the pair of operation pieces 44, and the operation pieces 44 are pushed inward as shown in FIG. Then, these operating pieces 44 swing inward around the hinge 48 .
As a result, the pressing end portion 44a of the operation piece 44 moves along the arc C, comes into contact with the slide surface portion S, and pushes the slide surface portion S up while sliding. As a result, the push-up force f shown in FIG. 5 acts.
In this embodiment, since the pair of operation pieces 44 exert a pushing force on the slide surface portion S, the bottle 2 can be stably pushed up.
In addition, since the pair of operation pieces 44 can be pushed by pinching them with one hand, the operation is easy.
In the state shown in FIG. 1, the engaging protrusion 14 can be raised within the lifting groove 50b, so that the bottle 2 is pushed up against the cover member 40 together with the cylinder.
On the other hand, since the stem 30 is fixed to the cover member 40 via the connecting tube portion 70 , the pump function of the discharger 20 is activated and the liquid is discharged from the stem 30 .
The liquid discharged from the stem 30 passes through the interior of the nozzle 64 and is sprayed from the nozzle port 68 .
When the pair of operating pieces 44 are released from being pushed, the operating pieces 44 are restored to their original positions, and the bottle 2 and the cylinder are returned to their original positions by the force of upward biasing means such as springs of the dispenser 20. descend.
Next, when the engaging protrusion 14 is pushed in the direction opposite to the direction indicated by the arrow in FIG. 2, it moves into the locking groove 50a and returns to the locked state.
