Is pushed down against the bias, and the liquid in the can is ejected as a mist from the spray hole 23 through the stem and the communication pipe. The head may have a plurality of spray holes opened on its upper surface.
[0010]
A cap 31 is fitted to the upper part of the container. From both the left and right portions of the cap peripheral wall 32, the engagement plates 33, 33 are suspended along the outer surface of the peripheral wall 12 of the base cylinder member 11. As shown in FIG. 3, the left and right sides of the cap are formed in parallel with each other, and the engagement plates 33 and 33 are also flat plates.
[0011]
As shown in FIG. 2, a first groove 34 is formed in the middle part of the engagement plate in the front-rear direction, and a second groove 35 is formed on the front side of the first groove, respectively. The part is vertically provided with its lower end opened to the lower surface of the engagement plate. In the illustrated example, the first concave portion is formed by a long hole 34a, and second long holes 36, 36 are formed on the left and right sides of the lower portion thereof, and between the lower portion of the long hole and the second long hole. A leaf spring 37 is formed. The leaf spring will be described later.
[0012]
Further, a pin shaft 13 and a vertical protrusion 14 are attached to both the left and right portions of the above-described base cylindrical member peripheral wall 12, and the pin shaft 13 enters the upper portion of the first concave portion 34 and the vertical protrusion 14. Are slidably fitted into the second recess 35.
[0013]
The aforementioned leaf spring is formed as shown in FIGS. A part of the side surface of the leaf spring on the long hole 34a side is formed on the pin shaft clamping portion 38, and the width of the long hole portion on both the upper and lower portions of the clamping portion is made narrower than the pin shaft diameter to form the narrow portion 39, 39, when the pin shaft 13 passes through the narrow portion, the leaf spring 37 is provided so as to be elastically deformed toward the second long hole 36 as shown in FIG. In the illustrated example, the narrow upper part is formed by providing a protrusion. In the example shown in the figure, the clamping portion 38 and the narrow portions 39, 39 form a cap positioning means. However, a concave-convex fitting portion is provided on the inner surface of the engaging plate and the outer peripheral wall of the base tube member, and these are arranged. It can also be a positioning means.
[0014]
When the cap 31 is pulled up with respect to the base cylinder member 11 and the upper narrow portion 39 reaches the pin shaft 13, the leaf spring 37 is elastically deformed, and the pin shaft enters the clamping portion 38 and stops. At this position, the upper portion of the vertical ridge 14 is fitted in the lower portion of the second concave portion 35, and the vertical ridge portion that fits in the lower portion of the second concave portion is centered on the pin shaft. The cap 31 is prevented from swinging in the front-rear direction.
[0015]
The cap 31 can also be rotated rearward with respect to the base cylinder member 11. In this case, the cap 31 is further pulled up from the position of the above-mentioned positioning. By this pulling up, the pin shaft 13 reaches the bottom surface of the first recess 34, and the upper end of the vertical protrusion 14 is in the wide guide recess 35a provided below the lower end of the second recess 35 as shown in FIG. Enter. From this state, the cap 31 can be rotated backward about the pin shaft 13 as shown in FIG. 8, that is, in a direction in which the lower end of the second concave portion 35 is separated from the upper end of the vertical protrusion 14.
[0016]
When the cap 31 is closed again, the cap is returned from the state of FIG. 8 around the pin shaft 13 as shown in FIG. At this time, since the upper end of the vertical ridge 14 enters the inclined guide recess 35a below the second recess 35, it can be returned to the closed state shown in FIGS.
[0017]
The container having the above-described configuration may be formed by inserting a foot between the push-down head 21 and the cap 31 and pushing down the head 21 when the cap is positioned as shown in FIGS. In this state, since the cap 31 is above the foot, for example, the mist rising upward through the gap between the toes adheres to the lower surface of the cap 31, and can be prevented from adhering to the human body.
[0018]
When there is no concern about the mist leakage, and when there is no risk of adverse effects even if it adheres to the human body due to mist leakage, the cap 31 can be tilted backward as shown in FIG.
[0019]
In the above configuration, the base tube member 11, the pressing head 21, and the cap 31 are each formed of a synthetic resin material.
[0020]
【The invention's effect】
The present invention is configured as described above. In the case of the first or second aspect, the cap 31 can be moved up and down with respect to the base tube member 11, and the upper portion of the vertical protrusion 14 in the short-positioned state. Fits into the upper part of the second concave part 35, so that the fitting part prevents the cap from swinging in the front-rear direction around the pin shaft 13, for example, even if the tip of the foot hits the cap. Will not fall down, so that the foot can be surely inserted between the press-down head 21 and the cap, and the head can be pressed down, and the cap can be protected even if mist ejected by the head press-down leaks upward. Therefore, adhesion to other parts of the human body can be reliably prevented.
[0021]
According to the third aspect, the holiday positioning mechanism can be simplified.
[0022]
According to the fourth aspect of the present invention, it is convenient that the spray mode can be selectively used depending on the actual situation even when the cap 31 is pulled up above the push-down head and positioned in the rear position or when the cap is tilted backward. .
