BACKGROUND OF THE INVENTION
The present invention relates to a stopper for prohibiting the operation of a pump mechanism by fitting the cap with a cap having a pump mechanism that discharges various liquid substances such as shampoo stored in the container. Is.
[0002]
[Prior art]
FIG. 1 shows an example of such a stopper. FIG. 1 (a) is a plan view and FIG. 1 (b) is a perspective view. The illustrated stopper 1 includes a substantially C-shaped fitting portion 2 and a substantially T-shaped knob 3 connected integrally therewith.
[0003]
2 shows a state in which the stopper 1 of FIG. 1 is mounted on a container with a pump. FIG. 2 (a) is a top view and FIG. 2 (b) is a cross-sectional view. The container 10 with a pump includes a container body 11 and a cap 12 with a pump. The cap 12 with a pump includes a cap part 13 and a pump part 14, and the cap part 13 is screwed to a screw thread 16 provided on a base part 15 of the container body 11 and is fixed to the container body 11 in an airtight manner. The pump unit 14 includes a cylinder unit 17 and a piston head 18, and a discharge pipe 19 extends from the piston head 18. The discharge pipe 19 communicates with a flow path (not shown) inside the cylinder portion 17 in order to discharge the contents in the container body 11. When the user presses down the piston head 18 when using the container 10 with the pump, the liquid contents (shampoo, emulsion, etc.) in the container body 11 are sucked up by a mechanism (not shown) in the cylinder part 17 and the cylinder part. 17 is discharged from the discharge pipe 19 through an internal flow path.
[0004]
Here, the stopper 1 is fitted with a cylindrical portion 13 a whose fitting portion 12 protrudes above the cap portion 13, and the upper surface of the stopper 1 is in contact with the lower end of the piston head 18. Therefore, the piston head 18 cannot be pushed down. By doing so, it is possible to prevent the piston head 18 from being inadvertently pushed down and the contents in the container 10 being discharged during transportation or non-use.
[0005]
When the stopper 1 is attached to and detached from the container 10, the knob 3 is picked with a finger, and the fitting portion 2 is pushed into the cylindrical portion 13a or pulled out.
[0006]
Such a stopper is required to be securely fixed to the container and to be attached and detached relatively easily. However, in the case of the conventional stopper 1 as described above, for example, when the user tries to attach / detach with a wet finger, it is difficult for the finger to slip and pinch the knob 3 reliably, and a certain amount of force is required for attachment / detachment. There is a problem that said.
[0007]
[Problems to be solved by the invention]
An object of the present invention is to propose a stopper for a container with a pump that solves the above-described problems, can be securely fixed to a container, and can be easily attached and detached.
[0008]
[Means for Solving the Problems]
The present invention relates to a container with a pump comprising a container main body and a cap that is airtightly attached to a base portion of the container main body and has a pump mechanism for discharging a liquid content contained inside the container main body. A stopper that is detachably fitted to the cap and prohibits the operation of the pump mechanism, and is fitted with the cap, and is fitted with the first and second substantially arc-shaped fitting portions arranged to face each other. And a stopper for a container with a pump, characterized by comprising a substantially π-shaped knob part integrally connected to one end of each of the first and second fitting parts.
[0009]
The stopper for a container with a pump according to the present invention has a structure in which a portion to be fitted with a cap has two substantially arc-shaped portions, and one end of each fitting portion is integrally connected to a substantially π-shaped knob portion. is doing. Therefore, when the user pinches the knob portion, the fitting portion of the stopper is deformed so as to spread slightly outward, so that it can be easily attached and detached. Further, when the finger is removed from the knob portion after the mounting, the fitting portion returns to its original shape, so that it is securely fixed to the cap. As described above, the stopper is easily elastically deformed, so that the stopper can be securely fixed to the cap and easy to attach and detach.
[0010]
In a preferred embodiment of the stopper for a container with a pump according to the present invention, the circumferential lengths of the first and second fitting portions may be 1/4 to 1/2 of the circumference. By setting the circumferential length of the fitting portion in this manner, fixing to the cap is guaranteed.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
[0012]
3A and 3B show an embodiment of the stopper according to the present invention. FIG. 3A is a plan view and FIG. 3B is a perspective view. The illustrated stopper 21 includes substantially arc-shaped fitting portions 22 and 23 and a substantially π-shaped knob 24 connected integrally therewith. That is, the portions 24a and 24b corresponding to the π-shaped feet of the knob 24 are connected to the fitting portions 22 and 23, respectively. As shown in the figure, the fitting portions 22 and 23 are arranged so that the respective concave surfaces face each other in order to fit the container as will be described later.
[0013]
The circumferential length of each of the fitting portions 22 and 23 of the stopper 21 is about 1/4 to 1/2 of the entire circumference. For example, the stopper 21 of FIG. 3 is about 3/8 (about 135 ° in angle). It is said. By setting within this range, the stopper can be securely fixed to the container and can be easily attached and detached.
[0014]
4 shows a state in which the stopper 21 of FIG. 3 is mounted on a container with a pump, FIG. 4 (a) is a top view, and FIG. 4 (b) is a cross-sectional view. The container 30 with a pump includes a container body 31 and a cap 32 with a pump. The cap 32 with a pump includes a cap part 33 and a pump part 34, and the cap part 32 is screwed to a screw thread 36 provided on a base part 35 of the container body 31 and is fixed to the container body 31 in an airtight manner. The pump part 34 includes a cylinder part 37 and a piston head 38, and a discharge pipe 39 extends from the piston head 38. The discharge pipe 39 communicates with a flow path (not shown) inside the cylinder portion 37 in order to discharge the contents in the container body 31. Since the container 30 is the same as the container 10 shown in FIG. 2 described above, description of its operation is omitted.
[0015]
The stopper 21 is fitted with a cylindrical portion 33 a whose fitting portions 22 and 23 protrude above the cap portion 33, and the upper surface of the stopper 21 is in contact with the lower end of the piston head 38. Therefore, the piston head 38 cannot be pushed down. By doing so, it is possible to prevent the piston head 38 from being inadvertently pushed down and the contents in the container 30 being discharged during transportation or non-use.
[0016]
The stopper 21 is attached to the container 30 as follows. First, the user pinches the portions 24a and 24b (see FIG. 3) corresponding to the π-shaped feet of the knob 24 of the stopper 21 with fingers. Then, the portions 24a and 24b of the knob 24 are slightly bent, and accordingly, the fitting portions 22 and 23 are slightly deformed so as to open outward. In this state, the cylindrical portion 33a of the cap 33 of the container 30 and the fitting portions 22 and 23 of the stopper 21 are fitted. Thereafter, when the finger is released from the knob 24, the fitting portions 22 and 23 return to the original state and are completely fitted with the cylindrical portion 33a. As a result, the stopper 21 is fixed to the cap 33.
[0017]
On the contrary, when removing the stopper 21 from the container 30, the knob 24 is similarly picked with a finger and the stopper is pulled out from the cylindrical portion 33a of the cap 33.
[0018]
The stopper 21 is configured such that when the user pinches the knob 24 with a finger, the fitting portions 22 and 23 are deformed so that they can be easily attached and detached, and when the user releases the finger, the original state is restored. ing. Therefore, it is possible to easily perform attachment / detachment while maintaining reliable fixation to the container even when the user operates with a wet finger, for example.
[0019]
As described above, since the stopper for a container with a pump according to the present invention has a structure that is easily elastically deformed, it can be securely fixed to the cap and can be easily attached and detached.
