Description

[Detailed description of the invention] The present invention relates to a liquid medicine container applicator stopper, and more particularly to a liquid medicine container structure in which the applicator stopper can be configured to have a low profile, so that the entire body including the container can be made compact when incorporated into the container. The purpose is to provide a coating stopper.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In each figure, 1 is a container housing a medicinal solution, and 2 is screwed onto the neck 3 of the container 1 through a thread 4 on its outer periphery. 5 is a cap attached to the opening of the container body.

The container body 1 has a vertically elongated shape and is a so-called squeeze container made of a resilient material such as a soft synthetic resin. There are surrounding areas.

The application stopper 5 includes a fixed cylinder member 7 inserted into the neck of the container body, an elevating cylinder member 8 that moves up and down within the fixed cylinder member 7, an applicator 9 fixed to the upper end of the elevating cylinder member 8,
and a rotary operating barrel 10 for raising and lowering the application body 9 via the elevating barrel member 8.

The fixed cylinder member 7 has a double cylinder in its lower half.
An inner cylinder 11 that communicates with the inside of the container body 1 stands up from the center of the bottom wall of the bottomed outer cylinder 12, and a screw groove 13 is formed on the inner periphery of the lower half of the outer cylinder 12. The diameter of the part is slightly reduced in a stepped shape, and the stepped part is engaged with the top of the mouth of the mouth and neck part 3, so that the lower half of the reduced diameter part is firmly inserted into the mouth and neck part 3. A protrusion 14 is provided on the outer periphery of the upper end of the inner cylinder 11 in a protruding manner.

The elevating cylinder member 8 has a protrusion or thread 15 that is screwed into the threaded groove 13 on the outer periphery of the lower end, and is disposed between the inner cylinder 11 and the outer cylinder 12 so as to be able to move up and down. The part between the tubes 11 and 12 is formed into a perfect circle, and the upper outer periphery protruding upward from both cylinders 11 and 12 is formed into a non-perfect circle, for example, a corner shape, and the small outer diameter part above the corner part is formed into a perfect circle. The coating body 9 is fixed.

The applicator 9 has a plurality of through holes 18 formed around the lower part of a rigid core tube 17 whose bottom wall is an inverted conical plug 16, and an engaging protrusion 19 provided on the outer periphery of the intermediate portion of the core tube 17. A sponge 20 such as urethane is coated on the outer surface of the core tube 17 so as not to block the through hole 18.
The engagement protrusion 19 is fitted into an engagement groove 21 on the inner periphery of the upper end of the elevating cylinder member 8.

The rotary operation cylinder 10 has a cylindrical shape with a lower half, which is a double cylinder, which is rotatably fitted into the upper half of the fixed cylinder member 7 so as to sandwich it therebetween. , an inner cylinder 22 fitted to the upper part of the elevating cylinder member 8;
The inner hole is formed into a non-circular hole, for example, a square hole, corresponding to the shape of the upper part of the elevating cylinder member 8, and the elevating cylinder member 8 is fitted into the rotary operation cylinder 10 so that it can move up and down but not rotate. The outer cylinder 23 has a mating structure, and an engaging protrusion 24 is provided on the inner periphery of the lower end of the outer cylinder 23 to fit into the engaging groove 6 so as to prevent it from slipping out.

Therefore, when the rotary operation tube 10 is rotated relative to the container body 1, the elevating tube member 8 rotates together with it, but on the other hand, since the elevating tube member 8 is screwed to the fixed tube member 7, the elevating tube member 8 rotates with respect to the container body 1. 8. Therefore, the application body 9 is raised and lowered by the rotation operation.

With this structure, normally, as shown in FIG. 1, the elevating cylinder member 8 is at the lowest position within the fixed cylinder member 7, and in this state, the applicator 9 is stored within the rotary operation cylinder 10.
The stopper 16 of the applicator 9 seals the upper end opening of the inner cylinder 11 and closes the inside of the container body 1.

To apply a chemical solution from this state, rotate the rotary operation cylinder 10 in a predetermined direction, raise the elevating cylinder member 8 and therefore the application body 9 as described above, and open the inner cylinder 11 as shown in FIG. The container body 1 may be squeezed by opening the cap, protruding the applicator body 9 to the outside of the rotary operating cylinder 10, and pressing it against the skin surface. Then,
The extruded medicinal liquid passes through the inner cylinder 11 and the elevating cylinder member 8, exudes from the sponge 20 of the applicator 9, and is applied to the skin surface. Incidentally, since the plug body 16 has an inverted conical shape, the amount of the chemical solution to be applied can be adjusted by adjusting the degree of elevation and descent of the plug body 16. Further, the elevating cylinder member 8 is connected to the rotary operation cylinder 1.
In contrast to 0, it is only necessary that the mounting member 8 and 10 be mounted so that they can be moved up and down but not rotated, and therefore both 8 and 10 may have an engagement structure of an engagement longitudinal strip and an engagement longitudinal groove.

Generally, in this kind of lifting mechanism using a rotary operation tube, the lifting member is engaged with the top wall of the cap-shaped rotary operation tube so as to be able to move up and down, but not to rotate. On the other hand, in the present invention, the rotary operating barrel 10 has a double-tube shape, and therefore, the elevating barrel member 8 can be raised and lowered at the lower end of the operating barrel 10 through the inner barrel 22, and engaged in a non-rotatable manner. As a result, compared to conventional general ones, the height of the integrated elevator cylinder member 8 and applicator 9 can be shortened by the height of the rotary operation cylinder 10, and it can be attached to the container body 1. In some cases, the overall size can be significantly reduced,
It is convenient to carry and handle. Further, during normal operation, that is, after use, the applicator 9 is stored in the rotary operating cylinder 10, so that the sponge 20 soaked with the chemical solution is prevented from coming into contact with clothes or other objects.
