DETAILED DESCRIPTION
[0042] In the following description, with reference to the drawings, the same reference numbers are assigned to the same components or to similar components having the same function, and overlapping description is omitted.
[0043]
[0044] As illustrated in
[0045] As illustrated in
[0046] A convex portion 1b for being attached to the container body 2 is provided in an annular shape on the outer peripheral surface on the rear side of the stepped portion 1a of the front tube 1.
[0047] The front tube 1 is provided with a tubular hole penetrating from an opening 1c at the distal end (or front end) to a rear end opposite the distal end, for accommodating the pipe member 3. A small-diameter tubular hole 1d is located at the distal end side (or front end portion) of the tubular hole, and a large-diameter tubular hole 1e having larger diameter than the small-diameter tubular hole 1d extends from the front end portion to the rear end of the front tube 1. At a portion between the small-diameter tubular hole 1d and the large-diameter tubular hole 1e, having a diameter that increases toward the large-diameter tubular hole 1e, concave portions 1f are arranged along a circumferential direction and extend substantially in the axial direction of the front tube 1. The concave portions 1f correspond to a same diameter as the large-diameter tubular hole 1e so as to extend continuously from the large-diameter tubular hole 1e. Convex portions 1g are formed between the concave portions 1f along the circumferential direction, and the concave portions 1f and the convex portions 1g are intermittently arranged side by side along the circumferential direction. For example, in this case, the front tube 1 includes four concave portions 1f and four convex portions 1g. The convex portions 1g correspond to a same diameter as the small-diameter tubular hole 1d so as to extend continuously from the small-diameter tubular hole 1d. The concave portions 1f and the convex portions 1g are for engaging the pipe member 3 in the rotational direction. The rear end face of the convex portion 1g is a stepped face 1h, and this stepped face 1h is the advance limit at which the distal end face of the pipe member 3 abuts (cf.
[0048] As illustrated in
[0049] A pair of small windows 2e that communicate inside and outside are opened to face each other in a tubular portion between the flange portion 2a and the male screw 2d of the container body 2. In addition, a locking convex portion 2f protruding radially outwardly for engaging the convex portion 1b of the front tube 1 is provided at a front side of the pair of small windows 2e in the axial direction. Further, on the inner peripheral surface of the container body 2, a plurality of ridges 2g (e.g., four in this case) extending with an elongated length from the bottom toward the distal end side are provided side by side in equal distributions (e.g., distributed at equal distances) along the circumferential direction to be engaged with the female screw member 5 in the rotational direction.
[0050] As illustrated in
[0051] A plurality of irregularities (e.g., four in this case) are continuously formed along the circumferential direction between the distal end portion 3a and the cylindrical portion 3b. A convex portion 3d which is flush with the cylindrical portion 3b, is inclined radially inwardly toward the distal end side, and extends along a predetermined length. A concave portion 3e is a through-hole that communicates inside and outside. The convex portion 3d is provided corresponding to the concave portion 1f of the front tube 1, and the concave portion 3e is provided corresponding to the convex portion 1g (cf
[0052] The pipe member 3 is provided with a tubular hole having a circular cross-sectional shape penetrating from an opening 3g at the distal end of the distal end portion 3a to the rear end. The tubular hole is a bar-shaped cosmetic material hole 3h that allows the bar-shaped cosmetic material M to advance and retreat. In the cylindrical portion 3b, gripping piece grooves 3i for accommodating a gripping piece 4f described later of the moving body 4 and being slidable are continuously provided to a plurality of locations (herein, four equally distributed positions) around the bar-shaped cosmetic material hole 3h, and an advancing/retreating hole 3j in which the bar-shaped cosmetic material M and the gripping piece 4f slide is configured by the bar-shaped cosmetic material hole 3h and the gripping piece groove 3i. It is noted that, in the cylindrical portion 3b, the second half of the advancing/retreating hole 3j has a larger diameter than the first half (cf.
[0053] Then, as illustrated in
[0054] As illustrated in
[0055] The core chuck 4a has a base portion 4e for abutting the rear end face of the bar-shaped cosmetic material M, of which outer shape substantially coincides with the outer shape of the bar-shaped cosmetic material M and the gripping piece 4f which is provided so as to protrude toward the distal end side at a plurality of positions in the circumferential direction of the outer peripheral surface of the base portion 4e (herein, four equally distributed positions) and grips the rear end portions of the bar-shaped cosmetic material M abutted against the base portion 4e by interposing the rear end portions between each other. The body portion 4b has a convex portion 4g extending backward in the axial direction at a position behind of the gripping piece 4f so as to be movable in the axial direction similar to that of the gripping piece 4f A small diameter portion is formed between the core chuck 4a and the body portion 4b, so that the core chuck 4a is easily bent.
[0056] Herein, the female screw member 5 is formed of a resin and is configured in a substantially cylindrical shape as illustrated in
[0057] Enlarged diameter portions 5c and 5d are provided at substantially the center and the rear end of the female screw member 5 in the axial direction, a concave portion 5e and a convex portion 5f are continuously provided in a gear shape at the in-phase four equally distributed positions of the enlarged diameter portions 5c and 5d in the circumferential direction, and the front and rear concave portions 5e and 5e are provided so as to be engaged with the ridge 2g of the container body 2 in the rotational direction (cf.
[0058] Then, as illustrated in
[0059] In this state, in a state where the first spring 6 is arranged between the rear end face of the flange portion 3c of the pipe member 3 and the enlarged diameter portion 5c of the female screw member 5, by screwing and tightening the male screw 4d of the core chuck 4a with the screw protrusion 5a and 5a of the female screw member 5, the first spring 6 is interposed between the rear end face of the flange portion 3c of the pipe member 3 and the enlarged diameter portion 5c of the female screw member 5.
[0060] Then, as illustrated in
[0061] Further, in this state, the pipe member 3 is biased due to the biasing force of the first spring 6, the distal end face 3f of the pipe member 3 abuts on the stepped face 1h of the convex portion 1g of the front tube 1 to reach the advance limit, and the distal end portion 3a of the pipe member 3 is in a state of protruding from the front tube 1 by a predetermined length. Then, herein, the state in which the bar-shaped cosmetic material M is flush with the distal end face of the pipe member 3 is set as the initial state.
[0062] As described above, according to the bar-shaped cosmetic material feeding container 100, the front tube 1 having the opening 1c at the distal end, the female screw member 5 provided with the screw protrusion 5a as a female screw inside and rotatable relative to the front tube 1, the moving body 4 provided with the male screw 4d that can be screwed with the screw protrusion 5a of the female screw member 5 on the outer surface and provided with the core chuck 4a for gripping the bar-shaped cosmetic material M at the distal end, and the pipe member 3 arranged inside the front tube 1, movable in the axial direction with respect to the front tube 1, and protruding from the opening 1c of the front tube 1 rotatable synchronously around the axial line are provided. The moving body 4 is accommodated so as to be movable in the axial direction and rotatable synchronously around the axial line inside the pipe member 3, and the opening 3g is provided at the distal end of the pipe member 3 so that the bar-shaped cosmetic material M can appear and disappear. The first spring 6 buffering the pipe member 3 and the second spring 5y having a different spring constant from the first spring 6 and buffering the core chuck 4a are provided.
[0063] Therefore, the following functions and effects are exhibited. That is, first, when the distal end of the bar-shaped cosmetic material M is slightly fed out from the initial state illustrated in
[0064] When the distal end of the bar-shaped cosmetic material M retreats or is consumed for coating so as to be flush with the distal end of the pipe member 3, and the pipe member 3 is pressed against the to-be coated portion in a state where the bar-shaped cosmetic material M does not protrude from the opening 3g of the pipe member 3, since the to-be coated portion is depressed and curved in a slightly concave state, the distal end of the bar-shaped cosmetic material M may reach (e.g., contact) the to-be coated portion. And, the pipe member 3 allowed to hit around the to-be coated portion retreats while retracting the first spring 6, and drawing can be performed on the to-be coated portion while the bar-shaped cosmetic material M protruding from the pipe member 3 retracts the second spring 5y and the bar-shaped cosmetic material M is protected.
[0065] Then, when the drawing is completed and the bar-shaped cosmetic material feeding container 100 is separated from the to-be coated portion, the first spring 6 is extended due to the biasing force, and thus, the pipe member 3 is advanced to return to the position of the original advance limit (the position of the distal end face 3f abutting on the stepped face 1h). And, the second spring 5y is expanded due to the biasing force, and thus, the bar-shaped cosmetic material M advances. Therefore, as drawing and consumption are carried out, the distal end of the bar-shaped cosmetic material M is located at a position that is retreated relative to the original position. When the distal end of the bar-shaped cosmetic material M is drawn too much and is retreated so as to be hidden in the pipe member 3, the bar-shaped cosmetic material M gripped by the core chuck 4a may be fed out by the relative rotation of the front tube 1 and the female screw member 5 (substantially the container body 2), so that the distal end of the bar-shaped cosmetic material M is flush with or protrudes from the distal end of the pipe member 3.
[0066] Therefore, drawing can be performed on the to-be coated portion in a state where the bar-shaped cosmetic material M, particularly the bar-shaped cosmetic material M having a small core diameter does not excessively protrude from the pipe member 3, and the core breakage during the drawing can be prevented. Further, since drawing can be performed even in a state where the bar-shaped cosmetic material M does not protrude from the opening 3g of the pipe member 3, the bar-shaped cosmetic material feeding container is more convenient than other bar-shaped cosmetic material feeding containers.
[0067] Further, since the container body 2 has a bottomed cylindrical shape and is attached to the front tube 1 so as to be relatively rotatable and the container body 2 accommodates the female screw member 5 inside and is engaged with the female screw member 5 so as to be rotatable synchronously around the axial line, the above-mentioned function can be suitably exerted.
[0068] Also, since the spring constant of the second spring 5y is greater than the spring constant of the first spring 6, the functions of the first spring 6 and the second spring 5y may be more suitably achieved.
[0069] Further, since the second spring 5y is integrally formed with the female screw member 5, the number of components is reduced.
[0070] The bar-shaped cosmetic material M may be incorporated in the bar-shaped cosmetic material feeding container 100 in accordance with, for example, the production process described below. The bar-shaped cosmetic material M to be used is produced to have a length corresponding to the length from the distal end of the front tube 1 (see
[0071] Concerning the production process referring to
[0072] If the length x in the axial direction between the distal end of the pipe member 3 and the distal end of the front tube 1 is longer than a length y in the axial direction between the distal end of the gripping piece 4f and the distal end of the base portion 4e, when the bar-shaped cosmetic material M is pressed from the opening 3g of the pipe member 3 using the above-described jig, before the jig abuts with the distal end of the front tube 1, the rear end face of the bar-shaped cosmetic material M may be crushed by abutting against the distal end of the base portion 4e. Note even when the length x in the axial direction between the distal end of pipe member 3 and the distal end of the front tube 1 is slightly longer than the length y in the axial direction between the distal end of the gripping piece 4f and the distal end of the base portion 4e, the bar-shaped cosmetic material may not be crushed depending on softness thereof.
[0073]
[0074] In a bar-shaped cosmetic material feeding container 200, the bar-shaped cosmetic material feeding container 100 is used as a so-called bar-shaped cosmetic material cartridge, and the bar-shaped cosmetic material feeding container 200 is configured by detachably (or “not detachably” in other examples) attaching an elongated holder tube 7 having a bottomed cylindrical shape to accommodate the container body 2 constituting the bar-shaped cosmetic material cartridge.
[0075] The bar-shaped cosmetic material feeding container 200 is configured by screwing of a female screw 7a formed on the inner peripheral surface of the distal end portion of the holder tube 7 with the male screw 2d (cf
[0076] According to the bar-shaped cosmetic material feeding container 200, since drawing can be performed with the holder tube 7 held by hand, the usability with easier drawing can be achieved. It is noted that the holder tube 7 may accommodate (or cover) the rear portion of the front tube 1 and the female screw member 5 from the rear side and may have a bottomed cylindrical shape that is rotatable synchronously (e.g., rotationally fixed) with the female screw member 5. For example, the cylindrical portion of the container body 2 may be further extended with an elongated length backward to be used as the holder tube 7.
[0077]
[0078] A difference between a bar-shaped cosmetic material feeding container 300 according to another example and the bar-shaped cosmetic material feeding container 100 is that, instead of the female screw member 5 including the second spring 5y, as illustrated in
[0079] The female screw member 15 is integrally formed of a resin to be configured in a substantially cylindrical shape, and a front tube portion 15a, the first spring 15x, a screw tube portion 15b, the second spring 15y, a locking tube portion 15c, and a rear end portion 15d are provided in this order from the distal end side to the rear end side.
[0080] The first spring 15x is a spring having a slit on a peripheral surface and forming a substantially spiral shape to connect the front tube portion 15a and the screw tube portion 15b.
[0081] Screw protrusions 15e as female screws to be screwed with the male screw 4d of the moving body 4 are provided at positions facing the inner peripheral surface of the screw tube portion 15b, respectively.
[0082] The second spring 15y is configured by connecting a plurality of annular portions 15m aligned apart from each other in the axial direction by pairs of connecting portions 15n that extend along a short length in the axial direction, with the connecting portions 15n of each pair facing each other. A first pair of connecting portions 15n are arranged so as to be shifted by 90° around the axial line with respect to the positions of a second pair of connecting portions 15n that are adjacent to the first pair in the axial direction.
[0083] Due to the springs having such a configuration, the spring constant of the second spring 15y is greater than the spring constant of the first spring 15x.
[0084] On the outer peripheral surface of the locking tube portion 15c, an engaging convex portion 15f for engaging with the front tube 11 in the axial direction is provided in an annular shape.
[0085] The rear end portion 15d protrudes backward in the axial direction from the rear end of the front tube 11 and is picked by the user, and herein, a plurality of (eight in this case) ribs 15g provided side by side along the circumferential direction and extended along the axial direction are picked by the user to be prevented from sliding.
[0086] As illustrated in
[0087] As illustrated in
[0088] Then, as illustrated in
[0089] Then, the relative rotating portion (rear end portion) 15d protruding outward in the axial direction from the rear end of the front tube 11 of the female screw member 15 and relatively rotatable with the front tube 11 is picked by the user, and when the rib 15g is prevented from sliding and is relatively rotated in the feeding direction of the core chuck 4a, the bar-shaped cosmetic material M is fed.
[0090] Even in the bar-shaped cosmetic material feeding container 300 configured in this manner, similarly to the previously described bar-shaped cosmetic material feeding container 100, since the bar-shaped cosmetic material feeding container has the front tube 11 having the opening 1c provided at the distal end, the female screw member 15 provided with the screw protrusions 15e and 15e as the female screws inside of the female screw member and rotatable relative to the front tube 11, the moving body 4 provided with the male screw 4d capable being screwed with the screw protrusions 15e and 15e as the female screws of the female screw member 15 on the outer surface and provided with the core chuck 4a for gripping the bar-shaped cosmetic material M at the distal end, and the pipe member 13 arranged inside the front tube 11 to be movable in the axial direction with respect to the front tube 11 and rotatable synchronously around the axial line to protrude from the opening 1c of the front tube 11, wherein the moving body 4 is accommodated inside the pipe member 13 to be movable in the axial direction and rotatable synchronously around the axial line, and the opening 3g that allows the bar-shaped cosmetic material M to appear and disappear is provided at a distal end of the pipe member 13, and the bar-shaped cosmetic material feeding container has the first spring 15x buffering the pipe member 13 and the second spring 15y having a spring constants different from that the first spring 15x and buffering the core chuck 4a, a similar function and effect as those of the previously described bar-shaped cosmetic material feeding container 100 can be exhibited.
[0091] Further, since the spring constant of the second spring 15y is greater than the spring constant of the first spring 15x, the functions of the first spring 15x and the second spring 15y may be realized.
[0092] Further, since the first spring 15x and the second spring 15y are integrally formed with the female screw member 15, the number of components is further reduced as compared with the bar-shaped cosmetic material feeding container 100, described above.
[0093]
[0094] In a bar-shaped cosmetic material feeding container 400, the previously described bar-shaped cosmetic material feeding container 300 is used as a so-called bar-shaped cosmetic material cartridge, and the bar-shaped cosmetic material feeding container 400 is configured by attaching an elongated holder tube 8 having a bottomed cylindrical shape to the female screw member 15 through a spring member 9 that is expandable and contractible in the axial direction so as to be rotatable synchronously.
[0095] Specifically, on the inner peripheral surface of the holder tube 8, a plurality of ridges 8g provided side by side in a plurality of the equal distributions along the circumferential direction and extend with an elongated length from the bottom toward the distal end side are engaged with the ribs 15g constituting the relative rotating portion of the female screw member 15, so that the female screw member 15 and the holder tube 8 are rotatable synchronously.
[0096] According to the bar-shaped cosmetic material feeding container 400, similarly to the previously described bar-shaped cosmetic material feeding container 200, since drawing can be performed with the holder tube 8 held by hand, the usability with easier drawing can be achieved.
[0097]
[0098] A difference between the bar-shaped cosmetic material feeding container of the example of
[0099] With reference to
[0100]
[0101] A difference between the bar-shaped cosmetic material feeding container of the example illustrated in
[0102] With reference to
[0103] It is to be understood that not all aspects, advantages and features described herein may necessarily be achieved by, or included in, any one particular example. Indeed, having described and illustrated various examples herein, it should be apparent that other examples may be modified in arrangement and detail is omitted. For example, in the previously described bar-shaped cosmetic material feeding container 100, the first spring 6 is used as a coil spring, and the second spring 5y is used as a resin spring integrally formed with the female screw member 5. In addition, in the previously described bar-shaped cosmetic material feeding container 300, the first spring 15x and the second spring 15y are used as resin springs integrally formed with the female screw member 15. However, the first spring 6 may be used as a resin spring integrally formed with the female screw member 5, and the second spring 5y or 15y may be used as a coil spring. In short, at least one of the first spring and the second spring may be formed integrally with the female screw member 5 or 15. With such a configuration, the number of components can be reduced.
[0104] Further, the screw protrusion 5a or 15e may be a continuous female screw.
