Abstract
Description
Technical Field
[0001] The present invention relates to a puff that can be used for makeup, handicrafts, etc., and particularly to a rotary puff that can rotate with respect to a handle.
Background Art
[0002] According to a conventional puff fixed to a handle, it is not easy to apply evenly due to uneven distribution of the coating material and uneven application of force.
[0003] If the puff can rotate with respect to the handle, for example, by rolling the puff on the foundation applied to the skin, the friction with the skin can be reduced and the uneven coating can be reduced.
[0004] As prior art of the rotary puff, Patent Documents 1-3 can be cited. The puff in Patent Document 1 can rotate, but the rotation is for contact with the cosmetics contained in the container and does not rotate with respect to the skin to be coated. The puff in Patent Document 2 rotates with respect to the skin to be coated, but since the rotation axis is perpendicular to the gripping part and the puff is in the shape of a roller, it is difficult to finely adjust the contact with the skin. Patent Document 3 has a structure in which a disk-shaped puff is rotated by a motor that pivotally supports it, and the mechanical configuration is large-scale.

Summary of the Invention
Problems to be Solved by the Invention
[0006] Therefore, the objective of this invention is to provide a rotating puff that allows for easy fine-tuning of contact with the skin or other target, contributes to the uniform application of cosmetics, has a simple structure, and is easy to assemble. [Means for solving the problem]
[0007] To solve the above problems, the rotary puff of the present invention has the following configuration. That is, it is a rotary puff in which the puff can rotate relative to a handle, comprising a puff portion having a substantially cylindrical puff on its outer surface, a handle, and a shaft connected between the handle and the puff portion, wherein the puff portion is connected to one end of the shaft, a bearing member is fitted to the outer surface of the shaft, and the outer surface of the bearing member is connected to the handle, so that the puff portion can rotate relative to the handle.
[0008] Here, the puff portion may be provided with a substantially cylindrical puff support member that is joined to the internal cavity of the puff, an annular projection is provided on the inner circumferential surface of the puff support member, and a groove that engages with the projection is provided on the outer circumferential surface of the shaft, thereby allowing the puff portion to rotate relative to the handle via sliding between the projection of the puff support member and the groove of the shaft, contributing to a wider range of puff rotation.
[0009] Furthermore, at least one notch may be provided in the axial direction from the open end of the puff support member, allowing the diameter of the open end of the puff support member to be expandable and contractible, and the puff portion to be detachably attached to the shaft, thereby simplifying assembly and contributing to the replacement of the puff.
[0010] Alternatively, the other end of the shaft to which the puff portion is connected may be made substantially cylindrical, with at least one notch extending substantially axially from its open end, and an enlarged diameter member may be inserted into the inner circumferential surface of the shaft where the notch is located, thereby contributing to the simplification of assembly.
[0011] Furthermore, the handle may be made into a hollow, roughly rod-shaped section, allowing the shaft to be housed within the hollow portion, thereby contributing to the simplification of the finished product. [Effects of the Invention]
[0012] According to the rotary puff of the present invention, although it has a simple structure that is easy to assemble, it is easy to finely adjust the contact with the object such as the skin. Therefore, cosmetics and the like can be evenly applied without burdening the object such as the skin.

Modes for Carrying Out the Invention
[0014] Hereinafter, embodiments of the present invention will be described. It should be noted that design changes can be made as appropriate without departing from the gist of the present invention, and the above-mentioned patent documents and conventionally known technologies can be incorporated.
[0015] Figs. 1-2 are a front view and a front sectional view of an embodiment of the rotary puff of the present invention. The rotary puff of this embodiment includes at least a puff portion (10), a shaft body (30), a bearing member (40), and a handle (50). The puff portion (10) includes a puff (11) and a puff support member (20).
[0016] In this embodiment, as shown in Fig. 1, only the puff (11) and the handle (50) are exposed. The puff (11) is a slender substantially cylindrical shape with a substantially spherical tip, the handle (50) is a substantially rod shape, and the axes of the puff (11) and the handle (50) coincide.
[0017] As shown in Fig. 2, the puff part (10) is connected to the handle (50) via a substantially rod-shaped shaft body (30) and a bearing member (40). That is, the puff part (10) is connected to the upper end part, which is one end of the shaft body (30), and an annular bearing member (40) is fitted on the outer peripheral surface in the middle of the shaft body (30), and the handle (50) is connected to the outer peripheral surface of the bearing member (40). Due to the intervention of the bearing member (40), the puff part (10) is rotatably supported with respect to the handle (50).
[0018] Fig. 3 is a front cross-sectional view of the puff (11), Fig. 4 is a front cross-sectional view of the puff support member (20), and Fig. 5 is a front view of the shaft body (30). Inside the substantially cylindrical puff (11), there is a substantially cylindrical cavity (12), and a substantially cylindrical puff support member (20) is inserted into the cavity (12), and the puff (11) and the puff support member (20) are joined. The cavity (13) at the lower end of the puff (11) has a larger diameter in order to avoid contact with the upper end part of the handle (50). For the joining of the puff (11) and the puff support member (20), an adhesive or a concavo-convex fitting is used. In the case of a concavo-convex fitting, it is convenient in terms of assembly to provide a protrusion extending in the axial direction and a concave groove engaging with the protrusion on the inner surface of the puff (11) and the outer surface of the puff support member (20), respectively.
[0019] As shown in Fig. 4, an annular protrusion (21) is provided on the inner peripheral surface of the puff support member (20), and as shown in Fig. 5, a concave groove (31) engaging with the protrusion (21) is provided on the outer peripheral surface of the shaft body (30), and the puff support member (20) and the shaft body (30) are engaged. The degree of engagement between the protrusion (21) and the concave groove (31) can control the rotatability of the puff part (10) with respect to the shaft body (30). For example, if the engagement between the protrusion (21) and the concave groove (31) is loosened, the puff support member (20) slides with respect to the shaft body (30). In this case, the puff part (10) can also rotate with respect to the shaft body (30), so it has two rotation means combined with the rotation via the above-mentioned bearing member (40), and various adjustments of rotation are possible.
[0020] Conversely, if the engagement between the protrusion (21) and the groove (31) is strengthened, the puff support member (20) can be fixed to the shaft (30) and secured so as not to rotate.
[0021] The degree of engagement between the protrusions (21) and grooves (31) can be adjusted by changing the shape of the protrusions (21) and grooves (31), but it can also be easily done by replacing the puff part (10). Figure 6 is a bottom perspective view of the puff support member (20). There are two notches (22) extending approximately axially from the open end at the lower end of the puff support member (20). Since the diameter of the open end of the puff support member (20) can be expanded and contracted through these notches (22), the puff portion (10) can be easily attached to and removed from the shaft (30), which facilitates replacement.
[0022] In this embodiment, there is one set of protrusions (21) and grooves (31), but multiple sets may be provided. There are two notches (22), but there may be one or many.
[0023] The lower end of the shaft (30) to which the puff portion (10) is connected is substantially cylindrical, as shown in Figure 5, and has two notches (32) extending substantially axially from its open end (33). The notch (32) in this shaft (30) functions similarly to the notch (22) in the puff support member (20), allowing the diameter of the open end (33) to be expanded or contracted. Reducing the diameter of the open end (33) makes it easier to fit the bearing member (40).
[0024] After the bearing member (40) is fitted, as shown in Figure 1, an enlargement member (60), such as a wound metal plate, is inserted around the inner circumferential surface of the shaft (30), preventing a reduction in the diameter of the open end (33) and contributing to the stable installation of the bearing member (40).
[0025] Figure 7 is a front cross-sectional view of the handle (50). The handle (50) is hollow and roughly rod-shaped, with the shaft body housed in its hollow portion (51). The inner circumferential surface of the upper part is provided with a recess (52) for joining the bearing member (40). The joint with the bearing member (40) is simple in terms of assembly, using a recess-recess fitting mechanism. [Industrial applicability]
[0026] As described above, the rotating puff of this invention is easy to assemble, easy to replace the puff, allows for fine adjustment of contact with the skin or other target, and enables uniform application of cosmetics, making it extremely useful in industry. [Explanation of Symbols]
