Description

  The present invention relates to a structure of a head employed in a cosmetic tube containing a liquid, gel-like or gel-like cosmetic such as a face-washing gel.

  For example, a facial cleansing gel as a basic cosmetic is generally contained in a soft tube container (see, for example, Patent Document 1). The tube container disclosed in Patent Document 1 includes a tube main body in which cosmetics are accommodated, and a head provided integrally therewith. A sponge or brush designed in a predetermined shape is attached to the tip of the head. When the user presses the tube body, the cosmetic is squeezed out of the head. The user uses the sponge or brush to extend the cosmetic on the skin and lather it.

Japanese Patent Laid-Open No. 2008-80086

  In order for the user to perform an effective face wash, there is a request (first request) that a large amount of fine bubbles must be formed from the squeezed cosmetics.

  However, conventional sponges and brushes have not been able to fully meet such demands. There is also a strong request (second request) for reliably avoiding damage to the skin when the face is scrubbed with foamed cosmetics.

  On the other hand, in order to improve the added value of cosmetics as products, the appearance design of tube containers has been devised conventionally. Therefore, many tube containers are designed exclusively, and as described above, the tube body and the head are designed for the cosmetic. In this case, a special design is applied to the shape of the sponge and brush provided on the head. Further, since the sponge or brush provided on the head is in direct contact with the user's skin, it is required to be gentle to the skin and washable to maintain cleanliness (third request).

  However, the conventional head is formed integrally with the tube main body because it is designed with an emphasis on design, and it is difficult to meet the third requirement. In addition, if the head is forcibly cleaned, there is a risk that the cleaning liquid may enter the tube body through the head, and cleaning is virtually impossible.

  The present invention has been made based on such a background, and an object of the present invention is to provide a cosmetic tube head that enables skin-friendly and effective face washing for the user and that the head cleanliness can always be maintained. It is to be.

  (1) The cosmetic tube head according to the present invention is applied to a tube body in which a storage chamber in which cosmetics are stored is defined and a nozzle portion communicating with the storage chamber is integrally formed. The cosmetic tube head is provided on a base body having a fitting recess formed to fit in the nozzle portion, a head main body protruding from the base, and having a guide tube for guiding the cosmetic, and the head main body. And a brush. The brush is composed of a fiber bundle in which a large number of fibers having a wire diameter of 0.01 mm to 0.04 mm are aligned in the longitudinal direction, and a lead-out path through which the guide tube is inserted and the cosmetic product is led out passes through the fiber bundle. Is formed.

  According to this configuration, the base portion of the head main body is fitted to the nozzle portion of the tube main body. At this time, the nozzle portion is fitted into the fitting concave portion of the base portion. When the user grasps (squeezes) the tube main body, the cosmetic (typically a face-washing gel) accommodated in the tube body accommodating chamber is discharged through the nozzle portion, and the cosmetic is provided on the base portion. Guided along the guide tube. A brush is engaged with the guide tube, and the cosmetic is exposed to the surface of the brush from the guide tube via a brush lead-out path. Since this brush consists of a bundle of very small diameter fibers, the user can make the cosmetics exposed on the surface into very thin bubbles on the skin and use the bubbles to irritate the skin. You can scrub without. The fiber constituting the brush is preferably animal hair having a wire diameter of 0.015 mm to 0.03 mm. Animal hair has a wire diameter that changes along the longitudinal direction, which promotes the formation of finer bubbles and is gentler to the skin. However, the fibers constituting the brush should not be limited to animal hair, and a resin having a wire diameter of 0.01 mm to 0.04 mm may be employed.

  (2) The brush preferably includes a flat surface extending in a direction intersecting with the longitudinal direction of the fiber, and the lead-out path is preferably opened on the flat surface.

  In this configuration, the cosmetic exposed from the brush lead-out path is immediately carried on the flat surface. Therefore, the user can foam the cosmetics more easily on the skin. This flat surface may be orthogonal to the longitudinal direction of the fibers constituting the brush, or may be a surface formed by cutting the brush diagonally.

  (3) It is preferable that a lock mechanism for fixing the brush to the head body is provided. The lock mechanism is provided on the brush, and includes a fiber holder placed on the base and a window through which the brush is inserted, and is screwed into the base with the brush inserted in the window. And a fixing ring having a clamping part that clamps the brush between the base part and the screw part.

  According to this configuration, since the brush is fixed to the head main body, the work of foaming and scrubbing the cosmetic product by the user is further facilitated. The fixing ring is screwed onto the base portion while being put on the brush. At this time, the brush protrudes from the window of the fixing ring. The holding part of the fixing ring holds the fiber holder provided on the brush in cooperation with the base part.

  According to this invention, since the brush is provided on the head body, the user can easily foam the cosmetic. Moreover, since the fibers constituting the brush are extremely thin, the user can gently scrub the skin using the foamed cosmetic. Moreover, since the head main body is not formed integrally with the tube main body but is fitted, the head main body is removed from the tube main body. As a result, the brush can be cleaned and always kept clean. In addition, since the head main body is attached to and detached from the tube main body, there is an advantage that a tube main body as a general-purpose product can be adopted.

  As shown in FIGS. 3 and 5, the brush assembly 18 includes a bottom plate 32 (corresponding to the “fiber holder” described in the claims) and a brush body 33 erected on the bottom plate 32 (claims). Equivalent to the “brush” described in the range). The bottom plate 32 is made of resin or metal. The brush body 33 is a fiber bundle in which a large number of animal hairs (cashmere in this embodiment) are bundled. The wire diameter (average wire diameter) of this animal hair is 0.019 mm. The type of animal hair is not particularly limited, and it is desirable that the wire diameter of the animal hair is 0.01 mm to 0.04 mm (preferably 0.015 mm to 0.03 mm). The effect by the brush main body 33 being comprised from this material is mentioned later.

  The bottom plate 32 has a disk shape having a predetermined thickness. The outer diameter of the bottom plate 32 substantially coincides with the outer diameter of the upper surface 30 of the base portion 20. In the present embodiment, a rectangular recess 44 is provided at the center of the bottom plate 32. A through hole 45 is provided at the center of the bottom of the recess 44, and the inner diameter of the through hole 45 corresponds to the outer diameter of the guide tube 21. A tray 46 is fitted in the recess 44 of the bottom plate 32. The tray 46 is made of metal or resin and binds the brush body 33. However, the tray 46 can be omitted. A through hole 47 is provided in the center of the bottom of the tray 46. The through-hole 47 has the same shape as the through-hole 46, and the centers of both coincide. The outer shape of the brush body 33 is a rectangular flat plate shape, and this outer shape is defined by the inner peripheral surface shape of the tray 46. The shape of the brush body 33 is reliably maintained by the tray 46. An upper surface 36 of the brush body 33 (corresponding to a “flat surface” recited in the claims) is a flat plane. In the present embodiment, the upper surface 36 is orthogonal to the longitudinal direction of the brush body 33 (that is, the longitudinal direction of the fibers constituting the brush body 33). As will be described later, the upper surface 36 may be inclined.

  A through passage 37 (corresponding to a “lead-out passage” described in claims) is formed directly above the center of the lower surface of the brush body 33. The through passage 37 opens on the lower surface of the brush body 33 and penetrates the brush body 33 in the vertical direction. Thereby, an opening 38 is formed in the upper surface 36.

The inner diameter of the decorative plate 19 corresponds to the outer diameter of the small diameter portion 29 of the base portion 20 so that the female screw 39 can be screwed with the male screw 31 formed on the small diameter portion 29. A top plate portion 40 (corresponding to a “clamping portion” described in claims) of the decorative plate 19 has a circular flat plate shape, and a window 41 is formed at the center. The window 41 has a substantially rectangular shape, and the brush body 33 is inserted through the window 41 as shown in FIG. The shape of the window 41 is not particularly limited as long as the brush body 33 is inserted in accordance with the outer shape of the brush body 33. The outer diameter of the decorative plate 19 corresponds to the outer diameter of the step portion 28 of the base portion 20.

  The head 12 is assembled to the tube main body 11 in the following manner.

  As shown in FIGS. 3 and 6, the base 20 is screwed into the tube body 11. Specifically, the nozzle portion 15 is fitted into the fitting recess 22 and the male screw 24 of the nozzle portion 15 and the female screw 27 of the base portion 20 are screwed together, so that both are securely fixed. The brush assembly 18 is put on the guide tube 21 of the base 20. Specifically, the guide tube 21 is inserted into the brush assembly 18 and is fitted into the through passage 37 of the brush body 33, and at this time, the bottom plate 32 of the brush assembly 18 is placed on the upper surface 30 of the base 20. Furthermore, the decorative board 19 is put on the base 20. At this time, the brush body 33 of the brush assembly 18 passes through the window 41 of the decorative plate 19 and protrudes from the decorative plate 19 (see FIG. 6).

  The decorative plate 19 is screwed into the small diameter portion 29 of the base portion 20. Accordingly, the bottom plate 32 of the brush assembly 18 is sandwiched and fixed between the upper surface 30 of the base portion 20 and the top plate portion 40 of the decorative plate 19. That is, a lock mechanism for fixing the brush assembly 18 to the head body 17 is configured. Since the outer diameter of the decorative plate 19 corresponds to the outer diameter of the step portion 28 of the base portion 20, the decorative plate 19 and the step portion 28 are smoothly continuous as shown in FIG. By assembling the head 12 to the tube body 11, the storage chamber 16 communicates with the upper surface 36 of the brush body 33 via the fitting recess 22 and the through passage 37.

  The cover 13 is made of resin or metal and has a cylindrical shape. A plug member 43 is provided at the center of the upper surface portion 42 of the cover 13 and hangs down as shown in FIG. In the present embodiment, the plug member 43 is formed in a round bar shape, but the outer shape of the plug member 43 is not particularly limited, and may be any one that closes the opening 38 formed in the upper surface 36 of the brush body 33.

The inner diameter of the cover 13 corresponds to the outer diameter of the step portion 28 of the base portion 20, and the outer diameter of the cover 13 corresponds to the outer diameter of the base portion 20. Therefore, the cover 13 and the base 20 are smoothly continuous in a state where the cover 13 is attached to the base 20.

[How to use the tube container 10 for cosmetics]

  When the user removes the cover 13, the brush body 33 is exposed. When the user grasps the tube main body 11, the cosmetics stored in the storage chamber 16 are discharged onto the upper surface 36 of the brush main body 33. The upper surface 36 is a flat surface. In addition, the brush body 33 is composed of a bundle of extremely thin animal hairs. Therefore, the user can make the cosmetics exposed on the surface 36 into a very thin foam on the skin, and can scrub without giving irritation to the skin using the foam. Furthermore, since the head 12 is removed from the tube main body 11, the head main body 33 can be cleaned, and the head 12 is always kept clean. In addition, the brush main body 33 may be comprised from the bundle | flux of resin hair. In this case, the thickness (wire diameter) of the resin bristles is set to 0.01 mm to 0.04 mm, preferably 0.015 mm to 0.03 mm.

  In the present embodiment, as shown in FIG. 4, the opening 38 through which cosmetics are discharged is located on the upper surface 36 of the brush body 33. Therefore, the cosmetic is immediately carried on the upper surface 36, and the user can more easily foam the cosmetic.

  In addition, since the brush assembly 18 is fixed to the head main body 17 by the upper surface 30 of the base 20 and the top plate portion 40 of the decorative plate 19, the user can further easily work to foam the cosmetic. Note that the locking mechanism may be omitted. That is, the decorative board 19 may be omitted. Also, the cover 3 can be omitted. In that case, the brush body 33 is directly attached to the upper surface 30 of the base 20.

  FIG. 7 is an exploded perspective view of the brush assembly 18 according to a modification of the present embodiment.

  In this modification, the brush body 33 has a first surface 34 and a second surface 35 arranged back to back, and the upper surface 36 is inclined. That is, the upper surface 36 is formed by obliquely cutting the brush body 33 so that the first surface 34 and the second surface 35 are continuous. The inclination angle of the upper surface 36 is not particularly limited.

  The cross-sectional shape of the brush body 33 can be changed to various shapes such as a circle, a polygon, a star, etc. in addition to a rectangle.
