[0013] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0014] As shown in FIGS. 1 to 5, in the first embodiment of the present invention, the roll-on type applicator 1 has an application ball 2 and a holding part 4 that is attached to the mouth part 3a of a container body 3 and rotatably holds the application ball 2, and can apply the contents of the container body 3 with the application ball 2. The holding part 4 has a base end side member 4a and a tip side member 4b that can be attached to the base end side member 4a. The tip side member 4b has an engagement holding part 4b1 that can rotatably hold the application ball 2 by engagement. The holding part 4 has a restriction part 4d that restricts the application ball 2 from slipping out of the engagement holding part 4b1 to the base end side when the tip side member 4b is attached to the base end member 4a (the state shown in FIG. 1). When the tip side member 4b is not attached to the base end member 4a (the state shown in FIG. 5), the engagement of the engagement holding part 4b1 with the application ball 2 can be released by pressing the application ball 2 toward the base end side (see the white arrow in FIG. 5). In this embodiment, the direction along the central axis O of the roll-on type applicator 1 (cylindrical wall 4a1) is referred to as the up-down direction, the direction from the base end to the tip end of the roll-on type applicator 1 along the up-down direction is referred to as the upward direction, the opposite direction is referred to as the downward direction, the direction perpendicular to the central axis O is referred to as the radial direction, and the direction going around the central axis O is referred to as the circumferential direction.

[0015] According to the above configuration, application can be performed by rotating the application ball 2 while the restricting portion 4d restricts the application ball 2 from slipping out in the attached state. Furthermore, when the tip side member 4b is removed from the base side member 4a for disposal after use, the application ball 2 follows the tip side member 4b by fitting into the fitting retaining portion 4b1, preventing the application ball 2 from accidentally falling off. Thereafter, the application ball 2 can be released from the fitting by pressing it toward the base side, and the application ball 2 can be separated. Therefore, a roll-on type applicator 1 that allows easy separation of the application ball 2 can be realized.

[0016] The application ball 2 is made of a material different from the base end member 4a and the tip end member 4b. With the above-mentioned configuration, the application ball 2 can be easily separated and disposed of, thereby realizing good recyclability. The application ball 2 is made of, for example, metal or resin, and the base end member 4a and the tip end member 4b are made of, for example, resin.

[0017] The fitting and holding portion 4b1 is constituted by an elastically deformable protruding portion 4c (see FIG. 4) that protrudes toward the base end, and the restricting portion 4d is constituted by the protruding portion 4c and a support portion 4a2 (see FIG. 4) that is arranged to face an outer surface 4c1 of the protruding portion 4c when the non-attached state is changed to the attached state, and the protruding portion 4c can restrict the application ball 2 from slipping out of the fitting and holding portion 4b1 toward the base end side by support from the support portion 4a2 contacting the outer surface 4c1 of the protruding portion 4c and contacting the inner surface 4c2 of the protruding portion 4c with the application ball 2 in the attached state, and the fitting with the application ball 2 can be released by pressing the application ball 2 toward the base end side in the non-attached state. According to the above configuration, the fitting and holding portion 4b1 can be efficiently constituted by the protruding portion 4c that constitutes the restricting portion 4d.

[0018] The restricting portion 4d is configured by a ball support portion 4a3 (see FIG. 1) that is provided on the base end side member 4a and that, in the attached state, can restrict the application ball 2 from slipping out from the fitting-and-holding portion 4b1 to the base end side by contacting the application ball 2. According to the above configuration, the ball support portion 4a3, which can be provided independently of the fitting-and-holding portion 4b1, can efficiently restrict the application ball 2 from slipping out.

[0019] The restricting portion 4d is composed of a protrusion 4c, a support portion 4a2, and a ball support portion 4a3, the tip side member 4b has an annular body 4b2 and an elastically deformable protruding piece 4b3 (see FIG. 4) protruding from the inner peripheral edge of the annular body 4b2 to the base end side and constituting the protrusion 4c, the base end side member 4a has a cylindrical wall 4a1 and a convex portion 4a4 (see FIG. 1) constituting the ball support portion 4a3 that protrudes radially inward from the cylindrical wall 4a1 and can restrict the application ball 2 from coming out of the fitting holding portion 4b1 to the base end side in the attached state by contacting the application ball 2, and the cylindrical wall 4a1 has an annular wall 4a5 constituting the support portion 4a2 at the tip portion (see FIG. 4). According to the above configuration, the restricting portion 4d composed of the protrusion 4c, the support portion 4a2, and the ball support portion 4a3 can be realized with a simple structure.

[0020] The protrusion 4c is composed of a pair of protruding pieces 4b3 facing each other, and the ball support portion 4a3 is composed of a pair of convex portions 4a4 facing each other. With the above configuration, the protrusion 4c and the ball support portion 4a3 can function well. The convex portions 4a4 are protrusions, but are not limited to this, and may be composed of, for example, ribs extending in an elongated manner in the vertical direction.

[0021] The distal end member 4b has an annular outer peripheral wall 4b4 that hangs down from the annular body 4b2 so as to fit onto the outer peripheral surface of the annular wall 4a5 when attached, and the outer peripheral wall 4b4 is rotatably connected to a portion of the cylindrical wall 4a1 below the annular wall 4a5 via a hinge portion 4e. According to the above configuration, the distal end member 4b can be easily removed from the proximal end member 4a by rotating the distal end member 4b via the hinge portion 4e during separation.

[0022] The cylindrical wall 4a1 has an inner cylindrical portion 4a6 that fits into the inner peripheral surface of the mouth 3a when the mouth 3a is attached to the mouth 3a of the container body 3 that forms a storage space S for storing contents inside, and a flange portion 4a7 that contacts the upper end surface of the mouth 3a when the mouth 3a is attached, and the tip side member 4b has an operating piece 4b5 that hangs down from the annular body 4b2 on the opposite side of the hinge portion 4e when viewed from the central axis O, and the operating piece 4b5 is hooked and locked on the flange portion 4a7 when attached, and can be operated to release the lock. According to the above configuration, the tip side member 4b can be easily removed from the base side member 4a by operating the operating piece 4b5 during separation.

[0023] The portion of the holding part 4 that is closer to the tip than the flange 4a7 is tapered toward the tip, and the operation piece 4b5 is disposed flush with the cylindrical wall 4a1 on the outer circumferential surface of this portion in the attached state. In this embodiment, the operation piece 4b5 is configured to be disposed so as to protrude from the outer surface (upper surface and outer circumferential surface) of the flange 4a7 in the attached state as shown in Figs. 2 and 3, but may be configured to be disposed flush with the outer surface of the flange 4a7 in the attached state as in the second embodiment shown in Figs. 6 and 7. This configuration allows the appearance of the roll-on type applicator 1 to be neat.
