Can be attached non-rotatably. Further, a second screw portion 7a formed in a female screw shape is provided on the inner peripheral surface of the tubular body 7. Although the second screw portion 7a in the present embodiment is provided as a double-threaded screw, it may be a screw with three or more threads or a single-threaded screw. Further, as shown in the drawing, the pitch of the second screw portion 7a is larger than the pitch of the female screw-shaped first screw portion 2d provided on the mounting body 2.

The shaft body 8 has a columnar shape, extends along the axis O, and is inserted into the insertion hole 2c of the mounting body 2. In this state, the shaft body 8 also inserts the seal member 4. The seal member 4 is slidable and in close contact with the outer peripheral surface of the shaft body 8 to prevent the liquid content of the accommodation space S from leaking along the outer peripheral surface of the shaft body 8.

As shown in FIG. 1, the lower end portion of the shaft body 8 is a coating tool located near the bottom portion 1a of the container body 1 in a state where the first screw portion 2d is screwed into the mouth portion screw portion 1d of the mounting body 2. 9 is attached. The coating tool 9 is used for applying the content liquid, and is formed in a brush shape, a brush shape, or a brush shape, for example, depending on the type of the content liquid, the coating destination, and the like.

A pair of protrusions 8a projecting outward in the radial direction are provided at the upper end of the shaft body 8. As shown in the cross section AA in FIG. 1, the pair of protrusions 8a pass through a pair of groove portions 2g provided in the upper tubular portion 2f, respectively, and each screw of the second screw portion 7a to be a double-threaded screw. It is screwed into the groove.

In the coating container 100 having such a form, when the content liquid is applied, the cap body 6 is rotated with respect to the container body 1 as shown in FIG. Here, since the outer peripheral wall 6b of the cap body 6 is rotatable with respect to the outer peripheral wall 2b of the mounting body 2, the cap body 6 can be rotated while leaving the mounting body 2 mounted on the container body 1. Here, since the tubular body 7 provided inside the cap main body 6 is non-rotatably attached to the cap main body 6, the tubular body 7 also rotates together with the cap main body 6. The protrusion 8a included in the shaft body 8 arranged inside the tubular body 7 fits in the groove portion 2g extending in the vertical direction and is also screwed into the second screw portion 7a. Therefore, when the tubular body 7 rotates together with the cap body 6, the protrusion 8a is guided by the second screw portion 7a and the shaft body 8 rises along the groove portion 2g. Then, when the rotation of the cap body 6 is continued, the upper end portion of the shaft body 8 abuts against the top wall 6a of the cap body 6 as shown in FIG.

Since the shaft body 8 pressed against the top wall 6a of the cap body 6 cannot rise any further, it rotates together with the cap body 6. Here, since the protrusion 8a provided on the shaft body 8 fits in the groove portion 2g of the mounting body 2, when the shaft body 8 rotates together with the cap body 6, the mounting body 2 also rotates together. Therefore, as shown in FIG. 3, the screwing between the first screw portion 2d of the mounting body 2 and the mouth screw portion 1d of the container body 1 is released, and the cap body 6 and the like are removed from the container body 1 together with the mounting body 2. be able to.

As shown in FIG. 4, the upper end of the shaft body 8 of the cap body 6 and the like removed from the container body 1 is moved toward the top wall 6a of the cap body 6, and the applicator 9 is close to the cap body 6. In position. That is, since the coating tool 9 is located near the finger holding the cap body 6, the work of applying the content liquid becomes easy.

If the resistance acting between the container body 1 and the mounting body 2 is small, the first screw portion is formed before the shaft body 8 rises when the cap body 6 is rotated with respect to the container body 1. There is a possibility that the mounting body 2 may come off from the container body 1 due to loosening of the screw between the 2d and the mouth threaded portion 1d, but in the present embodiment, the resistance acting between the container body 1 and the mounting body 2 In comparison, since the resistance acting on the tubular body 7 and the shaft body 8 is reduced, the shaft body 8 can be raised preferentially as described above. Further, in the present embodiment, since the pitch of the second screw portion 7a is larger than the pitch of the first screw portion 2d, the resistance acting between the second screw portion 7a and the protrusion 8a is the same as that of the first screw portion 2d. It is smaller than the resistance generated between the mouth thread portion 1d and the mouth portion screw portion 1d. Therefore, the action of preferentially raising the shaft body 8 becomes more reliable. Further, since the pitch of the second screw portion 7a is larger than the pitch of the first screw portion 2d, the shaft body 8 rises more quickly than the speed at which the mounting body 2 rises with respect to the container body 1. Therefore, as shown in FIG. 4, a state in which the applicator 9 is located close to the cap body 6 when it is removed from the container body 1 is more reliably realized.

The coating container 100 can be modified in various ways. For example, the cap body 6 and the tubular body 7 of the present embodiment are different members in consideration of the configuration of the mold and the like, but they can be integrally formed depending on the shape and the like. Further, although the mouth thread portion 1d is formed in the shape of a male screw and the first thread portion 2d is formed in the shape of a female screw, the relationship between the male screw and the female screw may be interchanged.

The coating container according to the present invention can be embodied in another embodiment. 5 to 8 are views showing a second embodiment of a coating container according to the present invention. The coating container 100A of the present embodiment basically has the same configuration as the coating container 100 described above, but instead of the mounting body 2 and the cap body 6, the mounting body 2A and the cap body 6A are used. To prepare.

The mounting body 2A includes a top wall 2a having the same configuration as the mounting body 2 described above. The outer edge of the top wall 2a is provided with a stepped outer peripheral wall 2h that extends downward, extends horizontally to increase the diameter, and further extends downward. The top wall 2a is provided with the same insertion hole 2c as the mounting body 2, and the inner peripheral surface of the outer peripheral wall 2h is provided with the first screw portion 2d. Further, an upper engaging projection 2j that projects outward in the radial direction is provided on the outer peripheral surface of the portion where the top wall 2a and the outer peripheral wall 2h are connected.

The cap body 6A includes a top wall 6a similar to the cap body 6 described above, and an outer peripheral wall 6d extending downward from the outer edge of the top wall 6a and extending above the outer peripheral wall 2h. .. As shown in FIG. 5, the outer peripheral wall 2h and the outer peripheral wall 6d are arranged in series, and both are exposed to the outside world. Further, at the lower end portion of the inner peripheral surface of the outer peripheral wall 6d, an inward claw portion 6e that engages with the upper engaging protrusion 2j to prevent and hold the cap body 6A against the mounting body 2A is provided.

When applying the content liquid, the cap body 6A is rotated with respect to the container body 1 as shown in FIG. 6 also in the coating container 100A of the present embodiment. As a result, the tubular body 7 rotates together with the cap body 6A, so that the shaft body 8 in which the protrusion 8a is screwed into the second screw portion 7a rises with respect to the cap body 6A. Then, when the rotation of the cap body 6A is continued, as shown in FIG. 6, the upper end portion of the shaft body 8 presses against the top wall 6a of the cap body 6A and stops ascending. Since the mounting body 2A rotates together with the main body 6A, the screwing between the first screw portion 2d and the mouth screw portion 1d is released, and the cap main body 6A and the like can be removed from the container main body 1.

In the cap body 6A removed from the container body 1, the shaft body 8 is moving toward the cap body 6A as shown in FIG. 8A, and the coating tool 9 is located close to the cap body 6A. That is, also in this embodiment, since the coating tool 9 is located near the finger holding the cap body 6A, the work of applying the content liquid becomes easy.

Further, since the outer peripheral wall 2h of the mounting body 2A in the present embodiment is exposed to the outside world, for example, while holding the outer peripheral wall 2h with one hand, the outer peripheral wall 6d of the cap body 6A is picked up with the other hand. As a result, as shown in FIG. 8B, the cap body 6A can be rotated with respect to the mounting body 2A. As a result, the shaft body 8 can be moved back and forth with respect to the cap body 6A, so that the position of the coating tool 9 can be changed according to the user's preference.
