By the way, such a coating ball is made of various materials. Here, when a metal or ceramic coating ball is used, it is recently formed of these materials because it has an excellent cooling feeling and a refreshing feeling when it comes into contact with the skin compared to a synthetic resin one. Things are increasing. On the other hand, the holding member for holding the coating ball is generally made of synthetic resin. For this reason, when disposing of these after the contents have been used up, there is a demand to remove the coated balls made of metal or the like from the holding member made of synthetic resin in order to separate each material in consideration of recyclability. .. Further, by removing the coating ball from the holding member, for example, the content liquid remaining between the coating ball and the holding member can be used up. Therefore, if the coating ball can be removed from the holding member, the coating ball is made of synthetic resin. It is also suitable for forming. However, if the coating ball comes off from the holding member during use, the coating ball may fall from the holding member and be lost, and the content liquid may overflow to the surroundings. Therefore, the coating ball is usually used. Is held so that it does not easily come off the holding member. Therefore, in the conventional roll-on type coating tool, it is difficult to remove the coating ball from the holding member.

An object of the present invention is to solve such a problem, and while the coated ball can be held by the holding member in the same manner as in the conventional case, for example, the coated ball is held when it is discarded.

The "up" direction and the "down" direction in the present specification and the like are basically the states shown in FIGS. 1 and 5 (the state in which the roll-on type coating tool is attached to the container body in an upright posture). ).

1 to 4 show a first embodiment of a roll-on container according to the present invention. The roll-on type container 100 of the present embodiment includes a container body 1, a roll-on type coating tool 2, and a cap 5. Further, the roll-on type coating tool 2 is composed of a holding member 3 and a coating ball 4.

The container body 1 has a bottomed tubular shape and is shaped like a bottle. More specifically with reference to the drawings, the container body 1 has a cylindrical body portion 1a extending upward from a bottom portion (not shown) and contracting inward in the radial direction from the upper end portion of the body portion 1a. It includes a shoulder portion 1b having a diameter, and a cylindrical mouth portion 1c extending upward from the inner edge portion of the shoulder portion 1b and opening upward. Further, a storage space S for storing the content liquid is partitioned in the inner space surrounded by the bottom portion, the body portion 1a, the shoulder portion 1b, and the mouth portion 1c of the container body 1. Further, a first screw portion 1d formed in a male screw shape is provided on the outer peripheral surface of the mouth portion 1c.

The holding member 3 is provided with a cylindrical container-side holding wall 3a that can be inserted into the mouth portion 1c and is fitted and held in the mouth portion 1c when inserted. A flange wall 3b extending radially outward is provided at the upper end of the container-side holding wall 3a. As shown in the figure, in the flange wall 3b, the back surface (lower surface) of the flange wall 3b comes into contact with the upper surface of the mouth portion 1c in a state where the container side holding wall 3a is completely inserted into the mouth portion 1c.

Further, the holding member 3 includes a ball-side holding wall 3c that is connected to the inner edge portion of the flange wall 3b to hold the coating ball 4. The ball-side holding wall 3c has an annular shape so as to surround the lower portion of the coating ball 4, and the upper end portion thereof is formed so as to be curved inward in the radial direction along the outer peripheral surface of the coating ball 4. .. Further, the ball-side holding wall 3c extends inward in the radial direction, and penetrates the support wall 3d having an annular protrusion for supporting the coating ball 4 from below on the upper end surface and the support wall 3d in the vertical direction. It is provided with an opening 3e. The maximum diameter of the ball-side holding wall 3c is smaller than the inner diameter of the mouth portion 1c. Therefore, the ball-side holding wall 3c can be inserted into the mouth portion 1c by displacing the holding member 3 in the inverted posture as shown in FIG.

The container-side holding wall 3a, the flange wall 3b, and the ball-side holding wall 3c (including the support wall 3d and the opening 3e included in the ball-side holding wall 3c) are referred to as the main body of the holding member 3 in the present specification and the like. Sometimes.

Further, the holding member 3 extends along the central axis O of the container body 1 (which is also the central axis of the container-side holding wall 3a) below the coating ball 4 which is not exposed to the outside world, and the lower end portion thereof. Is provided with a rod-shaped extruded portion 3f protruding below the container-side holding wall 3a. The extruded portion 3f shown in the figure is formed in a rod shape in a bottomed tubular shape, but the present invention is not limited to this form, and the extruded portion 3f may be formed in a rod shape in a tubular shape penetrating the bottom portion. It may be formed into a rod shape in the actual form.

Such an extruded portion 3f is integrally connected to the support wall 3d by an elastic portion 3g provided inside the opening 3e. The elastic portion 3g is elastically deformed when a pressing force is applied to the extruded portion 3f in the vertical direction to allow the extruded portion 3f to move in the vertical direction with respect to the support wall 3d. The elastic portion 3g of the present embodiment is composed of two elastic pieces 3h displaced by 180 ° in the circumferential direction, as shown in the arrow view along the arrow A shown in FIG. The elastic piece 3h extends radially inward from the inner edge of the support wall 3d provided with the opening 3e, further extends in an arc shape along the inner edge of the support wall 3d, and then radially inward. It is formed so as to extend toward and connect to the upper end portion of the extrusion portion 3f.

The coating ball 4 has a spherical shape and is made of various materials (metal, ceramic, or synthetic resin). The coating ball 4 of the present embodiment is held inside the ball-side holding wall 3c by pushing it from above the ball-side holding wall 3c. In the state where the coating ball 4 is held by the ball-side holding wall 3c, the upper portion of the coating ball 4 is exposed from the holding member 3. Further, a gap is formed between the ball-side holding wall 3c and the coating ball 4, and the coating ball 4 can rotate inside the ball-side holding wall 3c. Further, since this gap communicates with the opening 3e, if the holding member 3 is inserted into the mouth portion 1c and the container body 1 is displaced in the inverted posture, the content liquid of the accommodation space S can flow to the gap.

The cap 5 includes a disc-shaped top wall portion 5a and a cylindrical peripheral wall portion 5b extending downward from the outer edge portion of the top wall portion 5a. The top wall portion 5a includes a convex portion 5c located at the center of the top wall portion 5a and an annular wall 5d surrounding the convex portion 5c on the back surface thereof. A second threaded portion 5e having a female thread shape and a shape corresponding to the first threaded portion 1d is provided on the inner peripheral surface of the peripheral wall portion 5b.

The roll-on type containers 100 configured in this way are combined in the state shown in FIG. 1 during storage. In this state, the second screw portion 5e of the cap 5 is screwed into the first screw portion 1d provided on the mouth portion 1c, so that the cap 5 covers the holding member 3 and the coating ball 4 and is held by the mouth portion 1c. To. That is, by attaching the cap 5 to the mouth portion 1c, problems such as dust in the outside world not adhering to the coating ball 4 and the content liquid adhering to the coating ball 4 drying and solidifying are prevented. can do. Further, in this state, the coating ball 4 is sandwiched between the annular protrusion provided on the support wall 3d and the annular wall 5d and does not move, so that the coating ball 4 is held with the coating ball 4 when the roll-on container 100 is carried. It is possible to prevent problems such as the members 3 colliding with each other and making a noise.

Then, when applying the content liquid to the coating surface, the coating ball 4 is pressed against the coating surface in a state where the container body 1 is displaced in an inverted position, and the container body 1 is moved along the coating surface as it is, as described above. Since the content liquid is flowing in the gap between the ball-side holding wall 3c and the coating ball 4, the content liquid can be adhered to the coating surface via the coating ball 4.

After the content liquid contained in the container body 1 is used up, as shown in FIG. 2, the cap 5 is removed from the mouth portion 1c, and the roll-on type coating tool 2 is also removed from the mouth portion 1c. Then, as shown in FIG. 3, the roll-on type coating tool 2 is displaced in an inverted posture, and the ball-side holding wall 3c is inserted into the mouth portion 1c. When the ball-side holding wall 3c is inserted, the original surface of the flange wall 3b (the flange wall located on the front side when the holding member 3 is attached to the mouth portion 1c as shown in FIG. 1). Since the upper surface of 3b) comes into contact with the upper surface of the mouth portion 1c, the roll-on type coating tool 2 is supported by the mouth portion 1c in an inverted posture. In this state, the extruded portion 3f stands upward from the coating ball 4, and its tip portion is located above the container-side holding wall 3a.

After that, when the cap 5 is screwed into the mouth portion 1c, as shown in FIG. 3, the convex portion 5c provided on the top wall portion 5a comes into contact with the tip portion of the extrusion portion 3f. When the cap 5 is further screwed in, the extruded portion 3f moves downward together with the convex portion 5c, and the coating ball 4 is pressed by the extruded portion 3f. The extruded portion 3f is connected to the support wall 3d by the elastic portion 3g, and an excessive force is not required to move the extruded portion 3f itself downward. Further, when the cap 5 is screwed in, the force generated by the cap 5 in the axial direction is larger than the force for rotating the cap 5. Therefore, even if the force for screwing the cap 5 is small, the coating ball 4 can be used. It can be pressed strongly. In this way, as shown in FIG. 4, the coated ball 4 can be easily detached from the ball-side holding wall 3c. Since the detached coating ball 4 is dropped into the container body 1, it is possible to prevent problems such as the removed coating ball 4 rolling and the periphery of the container body 1 becoming dirty.

The roll-on container according to the present invention can be embodied in other embodiments. 5 to 7 show a second embodiment of a roll-on container according to the present invention.

It includes 30b, a ball-side holding wall 30c, a support wall 30d, an opening 30e, and an extruded portion 30f. The extruded portion 30f is integrally connected to the support wall 30d by the elastic portion 30g provided in the opening 30e. The elastic portion 30g of the present embodiment is composed of three elastic pieces 30h provided at equal angles in the circumferential direction, as shown in the arrow view along the arrow B shown in FIG. As shown in the partially enlarged cross-sectional view and the arrow view of FIG. 5, the elastic piece 30h has a relatively thin thickness, and is radially inward from the inner edge portion of the support wall 30d provided with the opening 30e. It extends so as to be curved downward and is connected to the outer peripheral surface of the extruded portion 30f.

In the roll-on type container 200 configured as described above, by attaching the cap 5 to the mouth portion 1c as shown in FIG. 5, dust and the like adhere to the coating ball 4 and the content liquid adhering to the coating ball 4 It is possible to prevent problems such as solidification. Further, the content liquid can be applied to the coating surface using the coating ball 4 by the roll-on container 200 in the same manner as in the roll-on container 100.

Then, after the content liquid contained in the container body 1 is used up, the roll-on type coating tool 20 is removed from the mouth portion 1c, and the roll-on type coating tool 20 is further displaced to the inverted posture, and the mouth portion 1c is as shown in FIG. The ball-side holding wall 30c is inserted into the ball-side holding wall 30c. As a result, the roll-on type coating tool 20 is supported by the mouth portion 1c in an inverted posture. After that, when the cap 5 is screwed into the mouth portion 1c, as shown in FIG. 6, the convex portion 5c provided on the top wall portion 5a comes into contact with the tip portion of the extrusion portion 30f. When the cap 5 is further screwed in, the elastic piece 30h is inverted and the extruded portion 30f moves downward as shown in FIG. 7, so that the coating ball 4 is pressed by the extruded portion 30f. As a result, the coating ball 4 can be easily detached from the ball-side holding wall 30c.
