Japanese Patent Laid-Open No. 2004-97549

  However, in the above-described bar-shaped cosmetic support, when a bar-shaped cosmetic material having a substantially elliptical cross section is inserted and held between the support pieces, the bar-shaped cosmetic material easily rotates and shifts between the support pieces. There is a tendency to grip diagonally, the grip strength becomes unstable, and as a result, for example, there is a risk that the bar-shaped cosmetic may come off from the support piece when an external force such as impact or vibration due to dropping of the bar-shaped cosmetic supply container is applied. There is a risk that the stick-shaped cosmetic will break.

  The present invention has been made to solve such problems. For example, when an external force such as an impact or vibration due to dropping is applied, the stick-shaped cosmetic material is prevented from coming off from the support piece and the stick-shaped cosmetic material is not broken. It is an object to provide a stick-shaped cosmetic support.

  Here, as a result of intensive research, the inventors of the present invention have the reason that the bar-shaped cosmetic material having a substantially elliptical cross section between the support pieces is easily rotated and misaligned by the support piece for the bar-shaped cosmetic material. This is due to the low guideability / restraint. The low guideability / restraint was found to be that the part with a small curvature of the bar-shaped cosmetic material is the gripping part, and the support piece has a substantially elliptical cross section. It has been found that if the outer peripheral surface related to the long axis having a larger curvature is gripped than the outer peripheral surface related to the short axis of the stick-shaped cosmetic, the guideability and restraint can be improved.

Therefore , the bar-shaped cosmetic support according to the present invention has a pair of support pieces that are provided facing each other and project forward, and a base portion that supports the rear end portions of these support pieces. In the bar-shaped cosmetic support that holds the rear end portion of the bar-shaped cosmetic material having a substantially elliptical cross section between, the support piece is on the outer peripheral surface of the bar-shaped cosmetic material having the substantially elliptical cross-section in the short axis. The outer peripheral surface of the long axis having a larger curvature than that of the rod-shaped cosmetic is supported by the outer peripheral surface of the rod-shaped cosmetic, and the inner peripheral surface of the support piece is a rod-shaped cosmetic. The side surfaces of the support pieces are parallel to the long axis, and the inner peripheral shape of the support pieces is related to the long axis of the bar-shaped cosmetic material. It is a shape that substantially matches the outer peripheral surface, the inner peripheral surface of the support piece has a sharp tip in the cross-sectional shape, Protrusions that sunk into the outer peripheral surface of the stick-shaped cosmetic material to be worn are provided on both sides of the long axis, and are formed along the axial direction. The protuberance has a long tip in the cross-sectional shape of the protuberance. It is characterized by being provided so as to face the direction intersecting the axis.

  According to such a bar-shaped cosmetic support, an outer peripheral surface on the long axis side of the rear end portion of the bar-shaped cosmetic having a substantially elliptical cross section is gripped by the pair of opposing support pieces, and the support piece Since the inner peripheral shape of the grip is substantially the same as the outer peripheral surface on the long axis side of the stick-shaped cosmetic to be gripped, the curvature of the grip portion is compared with the curvature when gripping the conventional short axis side. Large, improved guideability and restraint for bar-shaped cosmetics, difficult to rotate when inserting and mounting the bar-shaped cosmetics between the support pieces, and sticking the bar-shaped cosmetics almost straight between the support pieces Thus, the grip strength can be secured stably. For this reason, for example, when the external force acts such as impact or vibration due to dropping or the like, the stick-shaped cosmetic material is prevented from coming off from the support piece and the stick-shaped cosmetic material is not broken. Further, a protrusion provided on both inner sides of the support piece on both sides of the major axis and having a pointed tip in the cross-sectional shape formed along the axial direction of the stick-shaped cosmetic to be mounted. It sinks well into the outer peripheral surface, increasing the contact area with the stick-shaped cosmetic material and increasing the frictional resistance. For this reason, the stick-shaped cosmetic material is further prevented from coming off the support piece and between the support pieces. Further, the long shaft is mounted on both sides of the ridge (provided at a position excluding the long shaft) and the tip of the ridge in the cross-sectional shape faces the direction intersecting the long shaft. The force acting on the support piece via the ridge by the stick-shaped cosmetic material acts not only in the major axis direction but also in the minor axis direction, and the support piece opens outward in the major axis direction. Is reduced. For this reason, the stick-shaped cosmetic material is further prevented from coming off from the support piece.

Here, the ridge is characterized in that the tip in the cross-sectional shape of the ridge is provided so as to face the direction orthogonal to the long axis. Further, the ridge is characterized in that the tip in the cross-sectional shape of the ridge is provided so as to face the axis of the bar-shaped cosmetic. Further, when the protrusion is at the position on the long axis of the bar-shaped cosmetic material , the tip in the cross-sectional shape of the protrusion is directed to the position on the support piece side having the protrusion from the axis of the bar-shaped cosmetic material, Compared to the case where the force acting on the support piece via the ridge due to the stick-shaped cosmetic to be attached is that the tip in the cross-sectional shape of the ridge is directed to the support piece side opposite to the axis at the position on the long axis. Thus, since it is reduced in the major axis direction and enlarged in the minor axis direction, it is further reduced that the support piece opens outward in the major axis direction, and the stick-shaped cosmetic material is further prevented from coming off from the support piece. The

  As described above, according to the present invention, since the bar-shaped cosmetic material having a substantially elliptical cross section is gripped almost straight between the support pieces and the grip strength is stably secured, for example, impact or vibration due to dropping or the like It is possible to prevent the stick-shaped cosmetic from coming off and breaking when the external force is applied. Further, since the contact area between the support piece and the bar-shaped cosmetic material is increased and the frictional resistance is increased, it is possible to further prevent the bar-shaped cosmetic material from coming off and rotating. Further, since the opening of the support piece to the outside in the long axis direction is reduced, it is possible to further prevent the stick-shaped cosmetic from coming off.

  3 d of support pieces are provided so that it may protrude ahead in the outer peripheral surface which concerns on the long axis x of the base 3c of cross-sectional substantially ellipse shape. As shown in FIG. 3, the support piece 3d has an inner peripheral surface that substantially matches the outer peripheral surface of the stick-shaped cosmetic material M with respect to the long axis x, and holds the stick-shaped cosmetic material M between the support pieces 3d, 3d. . The gripping of the bar-shaped cosmetic M will be described later. As shown in FIG. 8, the support piece 3 d has side surfaces (upper and lower surfaces in the drawing) that are parallel to each other and a large arcuate surface of the outer surface, and has a large arc surface. The outer shape of the short axis position of the base portion 3c, that is, the inner shape of the outer shape of the minor axis position of the rod-shaped cosmetic M is located inside (the outer shape of the minor axis position of the rod-shaped cosmetic M does not come out in the minor axis y direction). It is configured. And this support piece 3d does not extend the inner peripheral surface to the position of the short axis y of the outer peripheral surface of the rod-shaped cosmetic M.

  As shown in FIGS. 7 and 8, a plurality of protrusions 3f extending in the axial direction are provided on the inner peripheral surface of each support piece 3d. In the present embodiment, as shown in FIG. 8, two protrusions 3f are provided as a pair with respect to one support piece 3d so as to face each other with the long axis x interposed therebetween. This protrusion 3f is for inserting into the outer peripheral surface of the stick-shaped cosmetic M to be inserted and attached, has a triangular cross section, and has a sharp tip 3g directed inward in the axial direction (paper surface). In the vertical direction). The protrusion 3f is disposed in the vicinity of the circumferential edge My on the inner peripheral surface of the support piece 3d.

  In addition, the ridge 3f is arranged so that the sharp tip 3g of the ridge 3f faces the direction intersecting with the major axis x (in other words, extends toward the intersecting direction), in other words, The sharp tip 3g is provided so as not to face in a direction parallel to the major axis x. In this embodiment, the protrusion 3f is provided such that its tip 3g faces in a direction perpendicular to the long axis x (in a direction parallel to the short axis y).

  Further, as shown in FIGS. 7 and 8, a flat surface 3h orthogonal to the major axis x is provided along the axis on the inner peripheral surface of the support piece 3d at a position on the major axis x. . The flat surface 3h is for preventing the sticky cosmetic material M from rattling. In addition, the code | symbol O of the position where the major axis x and the minor axis y in FIG. 8 have shown the axial center of the rod-shaped cosmetics support body 3 and the rod-shaped cosmetics M. FIG.

  As shown in FIG. 2, the bar-shaped cosmetic support body 3 having the support portion 3a and the shaft body portion 3b has a base 3c that enters the bar-shaped cosmetic hole 1a of the front tube 1 and a support piece 3d that is a front tube. 1 is inserted into the advance / retreat hole 1c so as to enter the support piece groove 1b. Further, the rod-shaped cosmetic support 3 has a shaft body portion 3b inserted into the front tube 1 and the operation tube 2, and its rotation stopper 3i enters the rotation stop groove 1f of the front tube 1, and its screw portion. 3m is inserted in the screw cylinder 4, and the male screw 3e is engaged with the screw projection 4a.

  And, as shown in FIG. 3, the first advance / retreat hole 1c of the front tube 1 has its rod-shaped cosmetic hole 1a close to the outer peripheral surface of the rod-shaped cosmetic M and the short axis y of the base 3c, and its support. The single groove 1b is configured to be close to the outer peripheral surface excluding the side surface (upper and lower surfaces in the drawing) of the support piece 3d, and the second advance / retreat hole 1d of the front tube 1 has its main body hole 1e close to the outer peripheral surface of the connecting portion 3j. In addition, the anti-rotation groove 1f is configured to be close to the outer peripheral surface of the anti-rotation 3i.

  Here, when assembling the bar-shaped cosmetic M, the bar-shaped cosmetic M is inserted from the rear end side into the bar-shaped cosmetic hole 1a of the front tube 1 as shown in FIG. It is abutted against the base 3c while being inserted between the supporting pieces 3d, 3d accommodated.

  At this time, as shown in FIGS. 2 and 3, the support pieces 3 d and 3 d grip the outer peripheral surface on the long axis x side of the rear end portion of the bar-shaped cosmetic M having a substantially elliptical cross section, Since the inner peripheral shape of the support piece 3d is a shape that substantially matches the outer peripheral surface on the long axis x side of the stick-shaped cosmetic M to be gripped, the curvature of the grip portion grips the conventional short axis y side. It is larger than the curvature of the case, and the guideability / restraint for the stick-shaped cosmetic M is enhanced. For this reason, the stick-shaped cosmetic M is difficult to rotate between the support pieces 3d and 3d and is not easily displaced, and is gripped almost straight between the support pieces 3d and 3d, and the grip strength of the stick-shaped cosmetic M is stably secured. Has been.

  Further, when the rod-shaped cosmetic M is attached, the protrusion 3f is provided on the inner peripheral surface of the support piece 3d on both sides of the major axis x and is formed along the axial direction. The bar-shaped cosmetic M to be mounted is sunk into the outer peripheral surface, the contact area with the bar-shaped cosmetic M is increased and the frictional resistance is increased, and the long axis x is sandwiched between the two and provided on both sides (long). Since the protrusion 3f (provided at a position excluding the shaft) is disposed in the vicinity of the circumferential edge My on the inner peripheral surface of the support piece 3d, the protrusion 3f is attached by the stick-shaped cosmetic M to be mounted. Thus, the force acting on the support piece 3d through is divided roughly in the short axis y direction, and therefore, the support piece 3d is reduced from opening outward in the long axis x direction.

  Here, especially in the embodiment, since the tip 3g of the ridge 3f is sharp, the ridge 3f is well embedded in the outer peripheral surface of the bar-shaped cosmetic M. Further, since the sharp tip 3g of the ridge 3f provided on both sides with the major axis x in between is facing the direction intersecting the major axis x, the ridge 3f is attached by the stick-shaped cosmetic M to be attached. The force acting on the support piece 3d is not all acting only in the major axis x direction but acting in the minor axis y direction, and in this embodiment, the force is supported via the protrusion 3f. The force acting on the piece 3d acts almost in the minor axis y direction, and therefore the support piece 3d is further reduced from opening outward in the major axis x direction.

  When the tip 3g of the protrusion 3f is pointed like this, the disposition position of the protrusion 3f with respect to the inner peripheral surface of the support piece 3d is the circumferential edge My of the inner peripheral surface of the support piece 3d. However, the present invention is not limited to this, and even if the position is not in the vicinity of the end edge My, the opening of the support piece 3d toward the outside in the major axis x direction is not sharp. It is reduced by the action in the direction in which the tip 3g faces.

  When the stick-shaped cosmetic M is attached, a flat surface 3h perpendicular to the major axis x is provided along the axis at a position on the major axis x on the inner peripheral surface of the support piece 3d. Therefore, even when the stick-shaped cosmetic M is attached and the stick-shaped cosmetic M is slightly shifted, the stick-shaped cosmetic M is surely brought into contact with the flat surface 3h. It is prevented.

  When the protrusion 3f is provided on the long axis x on the inner peripheral surface of the support piece 3d, or the protrusion 3f is the inner peripheral surface of the support piece 3d at a position excluding the long axis x. When the direction of the sharp tip 3g is provided so as to be parallel to the long axis x, the force acting on the support piece 3d via the protrusion 3f by the stick-shaped cosmetic M to be attached is the long axis. Since all acts only in the x direction and the opening of the support piece 3d to the outside in the long axis x direction becomes large, it cannot be adopted.

  In the bar-shaped cosmetic material supply container 100 shown in FIG. 2 configured as described above, when the operation tube 2 and the front tube 1 are rotated relative to each other, the screw projection 4a of the screw tube 4 and the male screw 3e of the bar-shaped cosmetic material support 3 are provided. The rod-shaped cosmetic support 3 is advanced and retracted according to the screw mechanism constituted by the rotation-preventing mechanism constituted by the rotation-preventing mechanism 3i of the rod-shaped cosmetic support 3 and the rotation-preventing groove 1f of the front tube 1. Appears and disappears from the tip of the front tube 1 and can be applied.

  In particular, according to the stick-shaped cosmetic feed container 100 of the present embodiment, for example, even if an external force such as impact or vibration is applied by dropping the stick-shaped cosmetic feed container 100, the stick-shaped makeup is supported by the support piece 3d. Since the material M is difficult to rotate and is not easily displaced, it is gripped almost straight between the support pieces 3d and 3d, and the grip strength of the stick-shaped cosmetic M is stably secured. The folding of the stick-shaped cosmetic M is prevented.

  Further, since the protrusion 3f of the support piece 3d increases the contact area with the stick-shaped cosmetic M and increases the frictional resistance, the stick-shaped cosmetic M is detached from the support piece 3d and between the support pieces 3d, 3d. Is further prevented from rotating.

  Further, since the protrusion 3f of the support piece 3d reduces the support piece 3d from opening outward in the long axis x direction, the stick-shaped cosmetic material M is further prevented from coming off from the support piece 3d.

  Further, since the stick-shaped cosmetic M is surely brought into contact with the flat surface 3h by the flat surface 3h of the support piece 3d and the rattle-shaped cosmetic M is prevented from rattling, the stick-shaped cosmetic M is not detached from the support piece 3d. Folding is further prevented. In addition, when it replaces with the flat surface 3h and a convex part is provided, since the said rod-shaped cosmetics M may not contact | abut a convex part, when the rod-shaped cosmetics M shift | deviate a little, it is unpreferable.

  FIG. 9 is a cross-sectional view showing a stick-shaped cosmetic support according to the second embodiment of the present invention, and corresponds to FIG. The bar-shaped cosmetic support 13 of the second embodiment is different from the bar-shaped cosmetic support 3 of the first embodiment in that the pointed tip 3g faces the direction perpendicular to the long axis x. The strip 3f is a point in which the pointed tip 13g is replaced with a ridge 13f facing the axis O, and the arrangement position of the ridge 13f with respect to the inner peripheral surface of the support piece 3d is the same as in the first embodiment. This is the vicinity of the circumferential edge My on the inner peripheral surface of the support piece 3d.

  Even in the second embodiment as described above, the protrusions 13f are provided on both sides of the long axis x and disposed in the vicinity of the circumferential edge My on the inner peripheral surface of the support piece 3d. Therefore, the force acting on the support piece 3d via the protrusion 13f by the stick-shaped cosmetic M to be attached is largely divided in the short axis y direction, and the support piece 3d is reduced from opening outward in the long axis x direction. Has been.

  Further, since the protrusions 13f are provided on both sides of the major axis x and the sharp tip 13g faces the direction intersecting the major axis x, the stick-shaped cosmetic M to be worn is attached. Thus, the force acting on the support piece 3d via the ridge 13f is not entirely applied only in the major axis x direction, but is also divided in the minor axis y direction so that the support piece 3d moves in the major axis x direction. The outward opening is further reduced.

  In addition, since the direction in which the sharp tip 13g of the protrusion 13f faces has a predetermined acute angle with respect to the short axis y, the effect of preventing the support piece 3d from opening outward in the major axis x direction is effective. , Smaller than the first embodiment.

  FIG. 10 is a cross-sectional view of the stick-shaped cosmetic support according to the third embodiment of the present invention, and corresponds to FIG. The point that the bar-shaped cosmetic support 23 according to the third embodiment is different from the bar-shaped cosmetic support 13 according to the second embodiment is that the pointed tip 13g of the rod-shaped cosmetic support 13 according to the second embodiment faces the axis O. The pointed tip 23g is a point replaced with a ridge 23f that faces the front side of the axis O at a position on the long axis x. That is, the ridge 23f is configured such that a sharp tip 23g thereof faces a position on the support piece 3d side having the ridge 23f from the axis O at a position on the long axis x. Moreover, the arrangement position of the protrusion 23f with respect to the inner peripheral surface of the support piece 3d is the same as in the first and second embodiments.

  Even if it comprises in this way, it cannot be overemphasized that opening of the support piece 3d to the outer side of the major axis x direction is reduced, and in addition, the direction and length which the front-end | tip 23g of the said protrusion 23f faces are long. Since the acute angle formed by the axis x is larger than that of the second embodiment in which the sharp tip 13g faces the axis O, the force acting on the support piece 3d via the protrusion 23f is the second embodiment. As compared with the second embodiment, it is largely divided in the minor axis y direction (subdivided into the major axis x direction), and the effect of preventing the opening of the support piece 3d to the outside is greater than that in the second embodiment.

  Although the effect of preventing the opening of the support piece is somewhat reduced from this, the protrusion is pointed toward the support piece on the opposite side (opposite side) from the axis O at the position on the major axis x. It is also possible to configure as described above. Even if it comprises in this way, it cannot be overemphasized that the force which acts on a support piece via a protrusion is divided | segmented into the short-axis y direction, and the opening prevention effect of a support piece arises.

  FIG. 11 is a cross-sectional view of a bar-shaped cosmetic support according to a fourth embodiment of the present invention, and corresponds to FIG. The bar-shaped cosmetic support 33 according to the fourth embodiment is different from the bar-shaped cosmetic supports 3, 13, and 23 of the previous embodiment in that two pairs of protrusions are provided for one support piece 3d. It is the point that set.

  Specifically, in the fourth embodiment, the pair of protrusions 33f and 33f that are opposed to each other with the major axis x interposed therebetween are arranged in the vicinity of the circumferential edge My on the inner peripheral surface of the support piece 3d. The pair of protrusions 33ff and 33ff which are provided and are opposed to each other with the long axis x interposed therebetween are positions on the long axis x side of the protrusions 33f and 33f on the inner peripheral surface of the support piece 3d (the edge My and the long axis x It is disposed at a substantially intermediate position).

  The protrusion 33f has a pointed tip 33g facing the axis O, and the protrusion 33ff has a pointed tip 33gg having a protrusion 33ff from the axis O at a position on the long axis x. It is configured to face the position on the 3d side.

  In the fourth embodiment, with respect to the protrusion 33f, the operation / effect when the protrusion 33f is disposed in the vicinity of the circumferential edge My on the inner peripheral surface of the support piece 3d. When the tip 33g of the ridge 33f is pointed in a direction crossing the major axis x (when the tip of the ridge is directed toward the axis O) In other words, the same effect and effect as the protrusion 13f of the second embodiment are obtained, and with respect to the protrusion 33ff, the pointed tip 33gg of the protrusion 33ff is oriented in the direction intersecting the major axis x. When provided (when the pointed tip of the ridge is directed to the position on the support piece side having the ridge from the axis O at the position on the long axis x), the operation and effect are exhibited.

  The present invention has been specifically described above based on the embodiment. However, the present invention is not limited to the above embodiment. For example, in the first to third embodiments, one support piece 3d is provided. In the fourth embodiment, two pairs of ridges are provided for one support piece 3d, but the number of pairs is limited. In addition, the direction of the pointed tip of the protrusion of one support piece 3d is directed to a different position on the long axis x for each pair (pair) of protrusions as in the fourth embodiment. May be configured so as to be directed to substantially the same position on the long axis x, may be configured to face in different directions, and the protrusion does not necessarily sandwich the long axis x. Need not face each other (facing directly), and may be displaced from each other in the direction of the major axis x. In the ridge having a sharp tip in the shape, the ridge is provided on both sides sandwiching the major axis x (they may be displaced in the major axis x direction) and along the axial direction If formed and provided so that the pointed tip thereof faces the direction intersecting with the long axis x, the support piece 3d is reduced from opening outward in the long axis x direction. Incidentally, from the viewpoint of preventing the support piece 3d from opening outward in the major axis x direction, the direction toward the pointed tip of the ridge is preferable from the axis O toward the support piece side having the ridge.

  Moreover, in the said embodiment, although the screwing mechanism is comprised by the male screw 3e of the rod-shaped cosmetics support body 3, and the screwing protrusion 4a of the screw cylinder 4, a screwing mechanism is a helical part or What is necessary is just to perform the same function as a screw thread, such as a projection group arranged intermittently or a projection group arranged spirally and intermittently.

  Further, according to the present invention, for example, as described in Japanese Patent Application Laid-Open No. 2001-252134, a tip cylinder, which is a cartridge containing a rod-shaped cosmetic support and a screwing mechanism inside, is detachably mounted on the main body. When the front tube and the main body are rotated relative to each other, the bar-shaped cosmetic support is advanced and retracted according to the operation of the screwing mechanism so that the bar-shaped cosmetic material protrudes from the tip of the front tube. For example, as described in Japanese Patent Application Laid-Open No. 11-75934, the front tube is rotatably connected to the rear end side of the front tube (actually, the front tube is rotatably connected via the middle tube). A support piece for supporting the stick-shaped cosmetic material is housed in the front tube, and the main body is provided with a female screw extending in the axial direction on the inner peripheral side thereof, and the support piece A push bar disposed on the rear side of the support bar is accommodated. A protrusion provided at the rear end of the push rod is screwed into a female screw on the inner peripheral side of the main body to form a screwing mechanism. When the leading tube and the main body are rotated relative to each other, according to the operation of the screwing mechanism. When the push rod advances and retreats, the support rod is pushed by the advancing push rod and the bar-shaped cosmetic material protrudes from the tip of the tip tube, while the tip tube and the main body rotate relative to each other in the opposite direction, the push rod moves according to the operation of the screwing mechanism. The support bar is retracted and locked by the support rod, and the support rod is pulled back to the original position in the front tube, so that the bar-shaped cosmetic material is immersed from the tip of the front tube, and the front tube is removed from the main body. When removed, the support bar is retracted to the original position in the front tube by the action of the return spring, and the bar-shaped cosmetic material can be applied to the bar-shaped cosmetic material feeding container configured to be immersed from the tip of the front tube, and Is provided with a slit pipe in the latter half as described in Japanese Patent Application Laid-Open No. 2004-97549, for example. A cylinder and a main body that accommodates a slit pipe portion of the front cylinder and is rotatably connected to the front cylinder. The front cylinder contains a support piece that supports the bar-shaped cosmetic material, and includes a support piece. A protrusion provided at the rear end of the rod protrudes outward through the slit of the slit pipe. When the front tube and the main body are rotated relative to each other to form a screw mechanism, the support rod advances and retreats according to the operation of the screw mechanism, and the bar-shaped cosmetic is projected and retracted from the tip of the front tube. The present invention is also applicable to a material feeding container, and in short, has a pair of support pieces that are provided facing each other and project forward, and a base portion that supports the rear end portion of these support pieces, Bar-shaped cosmetic support that holds the rear end of the bar-shaped cosmetic material having a substantially elliptical cross section between the support pieces The present invention can be applied to the body and all of the stick-shaped cosmetic feed containers provided with such a stick-shaped cosmetic support.
