In this state, the communication between the intermediate hole 9c and the measuring chamber 6 is cut off. At this time, the outer peripheral surface of the seal portion 24 and the inner peripheral surface of the sliding hole 19a may be sealed, or the first stopper portion 24c and the overhanging portion 19b may be sealed.

As shown in FIG. 1, the tip portion 26 of the coating plug 9 projects upward from the top portion 19 of the measuring cylinder member 7. An annular or arc-shaped engaged portion 26a is formed on the outer peripheral surface of the upper end portion of the tip portion 26 so as to project outward in the radial direction and extend in the circumferential direction.

As shown in FIGS. 1 and 2. When the operating member 50 moves while the coating plug 9 is located at the coating position, it engages with the measuring cylinder member 7 to elastically deform the measuring cylinder member 7 and reduce the volume of the measuring chamber 6. The operating member 50 includes a pressing portion 51 that can be pressed in the radial direction, and a locking portion 52 that moves in the container shaft O direction and locks to the measuring cylinder member 7 when pressed against the pressing portion 51.

As shown in FIG. 2, the locking portion 52 includes a tubular portion 53 extrapolated to the measuring cylinder member 7 and a ring portion 54 extending inward in the radial direction from the tubular portion 53. The lower end of the tubular portion 53 is located below the upper end of the fixing member 40. The upper end of the tubular portion 53 is located above the upper end of the peripheral wall of the connecting tubular portion 20. As shown in FIG. 1, the ring portion 54 gradually extends downward from the outside to the inside in the radial direction.

The locking convex portion 58 is locked to the inner surface of the locking concave portion 2d, and the locking convex portion 58 is restricted from being detached from the locking concave portion 2d in the container axis O direction. The locking convex portion 58 is slidably locked to the inner surface of the locking concave portion 2d along the radial direction. When the locking convex portion 58 slides inward in the radial direction on the inner surface of the locking concave portion 2d, the locking convex portion 58 is guided downward by the inner surface of the locking concave portion 2d.

In the pressing portion 51, when the lower portion 57 is pressed inward in the radial direction, the lower portion 57 elastically deforms inward in the radial direction starting from the portion where the intermediate portion 56 and the lower portion 57 are connected. do. Here, in the present embodiment, since the reinforcing rib 56a is formed in the intermediate portion 56, the pressing force against the lower portion 57 is suppressed from being transmitted to the intermediate portion 56 and the upper portion 55, and the lower portion 57 is effectively elastically deformed. Can be made to.
When the lower portion 57 elastically deforms inward in the radial direction and the locking convex portion 58 moves inward in the radial direction, the locking convex portion 58 slides on the inner surface of the locking concave portion 2d. As a result, the lower portion 57, the intermediate portion 56, and the upper portion 55 are integrally pulled down while the lower surface of the intermediate portion 56 and the bottom surface of the extension recess 2a approach each other in the container axis O direction. As a result, the locking portion 52 is also pulled down together with the pressing portion 51, and the ring portion 54 deforms the connecting cylinder portion 20 in the container shaft O direction.

The cap body 10 has a ridged tubular shape, and a female screw portion screwed to the male screw portion of the mouth portion 3 is formed on the inner peripheral surface at the lower portion of the peripheral wall thereof. The female thread portion may be a multi-thread thread such as a double thread thread. Instead of the cap body 10 being detachably screwed to the mouth portion 3, for example, the smooth outer peripheral surface of the mouth portion 3 may be detachably fitted to the smooth inner peripheral surface of the cap body 10. Alternatively, the cap body 10 may be detachably fitted to the mouth portion 3 undercut, and the like may be appropriately changed. Further, instead of attaching the cap body 10 to the mouth portion 3, for example, the cap body 10 may be attached to the measuring cylinder member 7.

The top wall of the cap body 10 projects downward, and the lower end portion is between the outer peripheral surface of the tip portion 26 of the coating plug 9 located at the coating position and the inner peripheral surface of the sliding hole 19a.

The inner cap 10A is formed with the above-mentioned female screw portion, pull-up cylinder 31 and contact portion 27. The outer cap 10B covers the inner cap 10A. In the illustrated example, the outer cap 10B covers the entire inner cap 10A. The outer cap 10B is formed in a humpback tubular shape. The inner cap 10A is fixed to the inside of the outer cap 10B in a state where relative movement in the circumferential direction and the container axis O direction is restricted.

When forming the coating container 1, first, the inner plug member 4, the measuring cylinder member 7, and the coating plug 9 are assembled to form the measuring coating tool. This measuring coating tool is fixed to the mouth 3 of the container body 2 filled with the contents via the fixing member 40, and the operating member 50 is arranged on the container body 2. At this time, for example, the pressing portion 51 of the operating member 50 is elastically deformed outward in the radial direction starting from the portion where the pressing portion 51 and the locking portion 52 are connected (the upper end portion of the upper portion 55). The stop portion 52 is extrapolated to the measuring cylinder member 7 and the fixing member 40. When the lower portion 57 of the pressing portion 51 reaches the outside of the body portion 2b of the container body 2 in the radial direction, the pressing portion 51 is restored and deformed in the radial direction to allow the locking convex portion 58 to enter the locking concave portion 2d.
After that, the coating container 1 is formed by screwing the cap body 10 to the mouth portion 3.

Hereinafter, the operation of the coating container 1 of the present embodiment will be described.

As shown in FIG. 1, before using the coating container 1, the lower end of the sealing portion 24 of the coating plug 9 fits inside the peripheral wall of the cylinder cylinder 12, and the measuring chamber 6 and the communication hole 5 communicate with each other. It is blocked.
In order to apply the contents in the container body 2 to the portion to be coated, first, the cap body 10 is moved upward and separated from the mouth portion 3 of the container body 2. At this time, the pulling protrusion 31a of the pulling cylinder 31 and the engaged portion 26a of the tip portion 26 of the coating plug 9 engage with each other in the container shaft O direction, so that the coating plug 9 is pulled up by the cap body 10. And move to the weighing position. When the male threaded portion of the mouth portion 3 and the female threaded portion of the cap body 10 are double-threaded threads (multi-threaded threads), the lead of the threads is larger than that of the single-threaded threads. Therefore, the amount of displacement in the container shaft O direction with respect to the amount of rotation of the cap body 10 in the circumferential direction can be increased. As a result, the coating plug 9 can be quickly moved upward, and the cap body 10 can be quickly detached from the mouth portion 3 of the container body 2.

When the coating plug 9 is moved to the measuring position, the first stopper portion 24c of the coating plug 9 comes into contact with the overhanging portion 19b (the opening peripheral edge of the sliding hole 19a) of the measuring cylinder member 7. From this state, the cap body 10 is further moved upward with respect to the mouth portion 3 of the container body 2, so that the pulling protrusion 31a of the pulling cylinder 31 of the cap body 10 is engaged with the tip portion 26 of the coating plug 9. The cap body 10 is removed from the container body 2 and the coating plug 9 by getting over the portion 26a upward.

Next, as shown in FIG. 3, the contents in the container body 2 are brought into the measuring chamber 6 through the communication hole 5 by placing the coating container 1 in the inverted position with the coating plug 9 located at the measuring position. Inflow. As a result, a predetermined amount of contents is weighed in the measuring chamber 6.
Next, as shown in FIG. 4, when the tip portion 26 of the coating plug 9 located at the measuring position is pressed against the portion to be coated, the coating plug 9 moves toward the coating position. In this process, the intermediate hole 9c is communicated with the inside of the measuring chamber 6, the second stopper portion 25a is abutted against the regulation portion 11b of the inner plug member 4, and the lower end portion of the seal portion 24 is attached to the peripheral wall of the cylinder cylinder 12. Fit inside.
As a result, in the coating container 1, the communication between the measuring chamber 6 and the communication hole 5 is cut off, the discharge hole 8 and the measuring chamber 6 communicate with each other, and the contents are applied to the portion to be coated from the discharge hole 8. Can be done.

When discharging a small amount of the weighed contents, with the coating stopper 9 located at the coating position, the coating container 1 is advanced toward the portion to be coated in the direction of the container shaft O, and the tip portion 26 of the coating stopper 9 is pushed forward. Press against the part to be coated. Then, for example, a small amount of the contents in the measuring chamber 6 are swung out from the discharge hole 8 or coated due to the momentum of the coating container 1 when moving forward, the impact when the coating plug 9 comes into contact with the portion to be coated, or the like. With the tip 26 of the stopper 9 pressed against the portion to be coated, the contents in the measuring chamber 6 travel along the surface of the coating stopper 9 (for example, the inner surface of the peripheral wall 9b) and a small amount from the discharge hole 8. It is discharged.

On the other hand, when a large amount of the weighed contents is discharged, the operating member 50 is moved while the coating plug 9 is located at the coating position. Then, the operating member 50 is locked to the measuring cylinder member 7, the measuring cylinder member 7 is elastically deformed, and the volume of the measuring chamber 6 is reduced. At this time, in the present embodiment, as shown in FIG. 5, the pressing portion 51 is pressed inward in the radial direction to be elastically deformed, and the locking portion 52 is moved in the container shaft O direction to move the connecting cylinder portion 20. The volume inside the measuring chamber 6 is reduced by elastically deforming. At this time, the top wall of the connecting cylinder portion 20 is elastically deformed upward from the portion where the top wall and the peripheral wall of the connecting cylinder portion 20 are connected as a starting point. As a result, the contents in the measuring chamber 6 are pressurized and a large amount is discharged from the discharge hole. When the pressing of the pressing portion 51 is released, the operating member 50 and the measuring cylinder member 7 are restored and deformed based on the elastic deformation force of the pressing portion 51 and the measuring cylinder member 7.

After use (after coating), the lower end of the pulling cylinder 31 of the cap body 10 is inserted into the gap between the inner peripheral surface of the discharge hole 8 and the outer peripheral surface of the tip 26 of the coating plug 9, and the pulling cylinder is inserted. With the pulling protrusion 31a of 31 abutting against the engaged portion 26a of the tip portion 26 from above the engaged portion 26a, the female threaded portion of the cap body 10 is attached to the male threaded portion of the mouth portion 3 of the container body 2. Screw in. As a result, the pull-up protrusion 31a is made to ride over the engaged portion 26a downward, and the cap body 10 is attached to the mouth portion 3 of the container body 2.

As described above, according to the coating container 1 according to the present embodiment, by changing the usage method of the coating container 1, the discharge mode of the contents can be easily switched and measured in the same coating container 1. The contents can be discharged in a small amount or in a large amount as needed.
When only a small amount of discharge can be performed as in the conventional coating container, it is difficult to confirm whether or not the entire amount of the contents measured in the measuring chamber 6 has been discharged. On the other hand, in the case where a large amount of discharge mode can be carried out as in the case of the coating container 1, when it is considered that the discharge of the entire amount of the contents is completed, the large amount of discharge mode is carried out to tentatively measure. Even if the contents remain in the chamber 6, the remaining contents can be forcibly discharged. As a result, the entire amount of the contents measured in the measuring chamber 6 can be reliably discharged. Such an action effect is particularly effective when a drug or the like, which is strictly required to use the entire amount of the weighed contents, is contained in the coating container 1 as the contents.

Further, the operating member 50 includes a pressing portion 51 and a locking portion 52. Therefore, the user presses the pressing portion 51 in the radial direction to move the locking portion 52 in the container shaft O direction, thereby locking the locking portion 52 to the measuring cylinder member 7 and locking the measuring cylinder member 7. It can be elastically deformed. Thereby, the operability at the time of discharging a large amount of contents can be improved.

Further, the pressing portions 51 are arranged in pairs with the container shaft O interposed therebetween. Therefore, when pressing the pair of pressing portions 51 in the radial direction, the pressing of the pressing portions 51 can be realized by, for example, holding the container body 2 by sandwiching it by hand. Thereby, the operability at the time of discharging a large amount of contents can be further improved.

Further, an arrangement recess 3a is formed in the mouth portion 3. Therefore, when the cap body 10 is attached to and detached from the mouth portion 3, the pressing portion 51 can be arranged in the arrangement recess 3a. As a result, it is possible to prevent the pressing portion 51 from becoming an obstacle when the cap body 10 is attached / detached.

The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

For example, the tip 26 of the coating plug 9 or the entire coating plug 9 may be made of a soft material, the tip 26 of the coating plug 9 may be formed into a curved surface, or only the tip 26 of the coating plug 9 may be formed. The coating feel of the coating plug 9 can be made by using a separate member made of a soft material, or by forming the coating plug 9 by insert molding so that only the tip portion 26 of the coating plug 9 is formed of the soft material. It is also possible to make it feel comfortable and comfortable with less irritation.

In the above embodiment, the discharge hole 8 is formed in the coating plug 9. However, the present invention is not limited to this. The discharge hole 8 may be formed in the measuring cylinder member 7. In this case, the inside of the top portion 19 which is the sliding hole 19a in the above embodiment can be adopted as the discharge hole 8. For example, by not fitting the coating plug 9 tightly in the top 19, the outer peripheral surface of the coating plug 9 and the inner peripheral surface of the top 19 (inner circumference of the discharge hole 8) with the coating plug 9 located at the coating position. The contents of the measuring chamber 6 can be discharged through the gap between the surface).

The operating member 50 may include only one pressing portion 51, or may include three or more pressing portions 51.
The operating member 50 may be in another form that does not have the pressing portion 51 and the locking portion 52.
The cap body 10 may not include both the inner cap 10A and the outer cap 10B, for example, the outer cap 10B may not be provided.
