Stick-shaped cosmetic feeding container

Technical field

TECHNICAL FIELD The present invention relates to a rod-shaped cosmetic material dispensing container which allows a rod-shaped cosmetic material having an elliptical cross section to be able to protrude and retract from a container.

Background art

Conventionally, a core chuck for gripping a rod-shaped cosmetic having an elliptical cross section is made to be able to advance and retreat within a cylindrical container for accommodating the rod-shaped cosmetic, so that the rod-shaped cosmetic can be protruded and retracted from the tip of the cylindrical container. Containers are on the market.

In this type of rod-shaped cosmetic material feeding container, a pair of rod-shaped cosmetic material holding portions of a core chuck are arranged in a radially opposed manner as arc-shaped claws, and the base end portion of the rod-shaped cosmetic material has a long axis side or On the short axis side, a notch is provided which is cut out flatly corresponding to the pair of claws, and a bar-shaped cosmetic material is gripped by the claw by inserting the claw into the notch. . In this stick-shaped cosmetic material feeding container, the container is downsized by adopting a configuration in which the outer peripheral surface of the nail and the outer peripheral surface of the rod-shaped cosmetic material are matched (for example, see Patent No. 2). 9 0 4 7 11 Reference).

As a result of studying the above-described technology, the inventors have found the following problems. In other words, in the above-mentioned stick-shaped cosmetic dispensing container, the outer peripheral surface of the nail and the outer peripheral surface of the stick-shaped cosmetic can be brought into contact with each other, so that the size can be reduced, but the base end of the stick-shaped cosmetic is flat. It is necessary to provide a notch, which makes the production cumbersome, increases the production cost, and makes the bar-shaped cosmetics brittle. Further, in the above-mentioned nail, it is difficult to say that the grip of the bar-shaped cosmetic material is sufficiently stable, and that the thickness of the nail is reduced in order to reduce the size, and the thickness of the nail is thus reduced. Therefore, the nail is likely to fall inward, so that when an external force such as an impact acts, for example, there is a risk that the stick-shaped cosmetic may break or fall out. Also, if the nails fall inward in this way, it is difficult to attach the stick-shaped cosmetic to the nails during assembly, and the manufacturing cost will increase. Get higher.

The present invention has been made in order to solve such a problem, and it is possible to reduce the manufacturing cost and the size of the container without making the bar-shaped cosmetic brittle, and to improve the shape of the bar-shaped cosmetic when external force acts.

As shown in FIG. 2, the chuck portion 7a inserted into the first accommodation hole 6j of the cartridge tube 6 is, as shown in FIG. 3, FIG. 4, FIG. 7, and FIG. A base portion 7c against which a portion is abutted, a gripping piece 7d as a rotation stopping mechanism and an advance / retreat guide mechanism that grips the proximal end of the rod-shaped cosmetic M and engages with the advance / retreat groove 6p of the cartridge cylinder 6. It has.

As shown in FIGS. 7 and 8, the base 7c is formed of an elliptical thick plate that substantially matches the elliptical rod-shaped cosmetic material M.

As shown in Fig. 8, the gripping pieces 7d protrude toward the distal end side at four positions on the outer peripheral position excluding the long axis and the short axis of the base 7c, as shown in Figs. 4 and 7. It is provided. Thus, when the base 7c is divided into four regions by the long axis and the short axis, it is preferable that at least one gripping piece 7d is arranged in each of the four regions. In the present embodiment, these four gripping pieces 7d are symmetrically arranged with respect to the long axis and the short axis of the base 7c.

As shown in FIGS. 4 and 8, the four gripping pieces 7 d have an inner peripheral surface 7 X and an outer peripheral surface 7 y formed in an arcuate curved surface, and have an outer peripheral line as compared with an inner peripheral line in a cross section. It has a substantially fan-shaped shape that is elongated. The inner peripheral line is formed in an arc shape along the outer shape of the rod-shaped cosmetic material M, so that the inner peripheral surface 7X is configured to be able to hold the rod-shaped cosmetic material M, and the outer peripheral line is positioned on the long axis side. It is a line that makes the fan smaller as you go.

As shown in FIGS. 4, 7, and 8, the inner circumferential position of the end face of the gripping piece 7d has a tapered surface 7d for smoothly guiding the rod-shaped cosmetic material M between the gripping pieces. 4 and 8, the inner peripheral surface 7X is provided with a protruding shape 7f extending along the axial direction, and these four gripping pieces 7d are rod-shaped cosmetics, as shown in FIGS. While holding M, the protrusion 7 f of the inner peripheral surface 7 X prevents the rod-shaped cosmetic M from moving in the rotation direction. Then, as shown in FIG. 3, FIG. 4, and FIG. 6 i is formed so as to be close to the outer peripheral surface of the elliptical rod-shaped cosmetic material M, and the advance / retreat groove 6 is to be close to the outer peripheral surface of the substantially fan-shaped gripping piece 7 d. It is formed.

As shown in FIG. 1, the brush holder 4 at the rear end of the cartridge container 3 is mounted so as to close the opening at the rear end of the cartridge container 3, and is held by the brush holder 4 to hold the cartridge container. The screw brush 5 as an applicator exposed from 3 is covered by a tail cap 9 detachably mounted on the brush holder 4.

When assembling the stick-shaped cosmetic supply container 1 having such a configuration, first, the stick-shaped cosmetic cartridge 2 is assembled as a unit.

When assembling the rod-shaped cosmetic power cartridge 2, first, while rotating the spiral cylinder 8 and the core chuck 7 relatively, the core chuck shaft 7b of the core chuck 7 is opened at the distal end of the spiral cylinder 8. The spiral groove 8a of the spiral insertion tube 8 and the screwing projection 7g of the core check shaft 7b of the core chuck 7 are screwed into the screw tube 8 and fed to the rear end side.

Next, this assembly is moved to the position of the gripping piece 7 d of the chuck 7 a and the cartridge cylinder.

The cartridge 6 is inserted into the opening of the rear end of the cartridge cylinder 6 from the chuck portion 7a on the front end side so that the position of the advance / retreat groove 6p of 6 is matched.

Here, the gripping piece 7 d easily falls inward, and may fall inward due to molding shrinkage or the like.In the past, it was necessary to lengthen the cooling time during molding and adjust molding conditions, etc. However, in the present embodiment, even when the gripping piece 7 d having a substantially fan-shaped cross section is tilted inward, the gripping piece 7 d is close to the outer peripheral surface of the gripping piece 7 d of the cartridge cylinder 6 (the gripping piece 7 d). As it enters the advance / retreat groove 6p, the inward fall of the gripping piece 7d is corrected according to the advance / retreat groove 6p and opens normally.

Then, by contacting the distal end surface of the spiral cylinder 8 to the inner peripheral step 6X of the cartridge cylinder 6, the annular projection 8b of the spiral cylinder 8 fits into and engages with the annular groove 6h of the cartridge cylinder 6. Thus, the assembly is mounted on the cartridge cylinder 6 so as to be relatively rotatable. Next, the stick-shaped cosmetic M is inserted into the opening at the distal end of the cartridge tube 6 from the base end side. At this time, since the gripping piece 7d is corrected by the advance / retreat groove 6p and is normally opened, the stick-shaped cosmetic M can be easily attached to the gripping piece 7d. Then, the rod-shaped cosmetic material M is gripped by the chuck portion 7a of the core chuck 7, whereby the rod-shaped cosmetic material cartridge 2 is obtained.

Next, the rod-shaped cosmetic cartridge 2 thus obtained is inserted into the opening at the end of the cartridge container 3 from the rear end side, and the outer peripheral step 6 b of the cartridge tube 6 is inserted into the distal end surface of the cartridge container 3. , The engaging projection 6 g of the cartridge tube 6 is fitted into and engaged with the annular groove 3 c of the cartridge container 3, and the cartridge tube 6 is detachably attached to the cartridge container 3 and is relatively rotatable. At the same time, the elastic projection 8c of the spiral cylinder 8 engages with the engaging portion 3b of the partition 3 of the cartridge storage container 3, and the spiral cylinder 8 is non-rotatably connected to the cartridge storage container 3. Thereby, the stick-shaped cosmetic supply container 1 is obtained.

As described above, in the present embodiment, since the rod-shaped cosmetic cartridge 2 is assembled as a unit and then attached to the cartridge accommodating container 3, the assembly of the rod-shaped cosmetic feeding container 1 is facilitated, and the manufacturing cost is reduced. Reduction has been achieved.

Next, a case where the stick-shaped cosmetic material M is applied by using the stick-shaped cosmetic material feeding container 1 will be described. In this case, the large-diameter portion 6a exposed from the cartridge housing container 3 of the cartridge cylinder 6 is picked, and the cartridge housing container 3 is picked up, and these are relatively rotated. Here, the description will be made on the assumption that the cartridge container 3 is rotated. Then, since the engaging portion 3b of the partition 3 of the cartridge storage container 3 and the elastic protrusion 8c of the spiral tube 8 of the rod-shaped cosmetic force cartridge 2 are engaged in the rotating direction, the spiral tube 8 Force It rotates together with the cartridge container 3. At this time, the cartridge container 3 rotates against the rotational resistance between the cartridge cylinder 6 and the engagement protrusion 6 g of the cartridge cylinder 6. At this time, the core check 7 having the screw projection 7 g screwed into the spiral groove 8 a of the spiral cylinder 8 serves as a gripping piece 7 d force S, a rotation stopping mechanism for the cartridge cylinder 6, and an advance / retreat guide mechanism. Since it is engaged with all the advance / retreat grooves 6 p so as to be non-rotatable and movable in the axial direction, the rod-shaped cosmetic material M advances out of the cartridge tube 6 and is fed out from the end of the cartridge tube 6. Then, when the stick-shaped cosmetic material M is fed out to a desired length, the relative rotation between the cartridge container 3 and the cartridge tube 6 is stopped. Then, according to the rotational resistance generated between the engaging projection 6 g of the cartridge tube 6 and the annular groove 3 c of the cartridge container 3, the cartridge container 3 and the cartridge tube 6 are maintained in a predetermined engaged state. Be held.

Therefore, in this state, the user may hold the cartridge container 3 and apply the stick cosmetic M. At this time, an external force acts on the cartridge tube 6 from the application surface via the stick-shaped cosmetic material M and the rotation stopping mechanism, but the rotation of the cartridge tube 6 is prevented by the rotation resistance.

Here, when the cartridge container 3 and the cartridge cylinder 6 are further rotated relative to each other, and the core chuck 7 is further moved in the unwinding direction and is unreeled to the maximum, the core chuck 7 reaches the forward limit and exceeds the core chuck 7. Is prevented from moving forward.

If the relative rotation is further continued in this state, the advancement of the core chuck 7 is prevented, so that the engaging portion 3 b of the partition 3 of the cartridge container 3 b force ⁵ ; the elastic protrusion 8 c of the spiral cylinder 8. The cartridge cylinder 6, the core chuck 7, and the spiral cylinder 8 are integrated with each other, and are rotated relative to the cartridge accommodating container 3 to idle. Thus, the elastic projection 8c of the spiral cylinder 8 functions as a so-called torque limiter.

When the application is completed, the user rotates the cartridge container 3 and the cartridge tube 6 relatively in the opposite direction to the above, so that the stick-shaped cosmetic M is drawn into the cartridge tube 6.

Here, if it becomes necessary to replace the stick-shaped cosmetic M due to wear or the like, the stick-shaped cosmetic cartridge 2 is removed from the cartridge container 3 and the replacement (new) stick-shaped cosmetic cartridge 2 is replaced with the above. Insert the cartridge into container 3 in the same manner as It is necessary to improve convenience and practicality.

By the way, if such a stick-shaped cosmetic dispensing container 1 is pressed into the bag while carrying it, or if the stick-shaped cosmetic dispensing container 1 is dropped on, for example, a floor, the rod-shaped cosmetic dispensing container 1 is dropped. An unexpected external force acts on the feed container 1.

However, in the rod-shaped cosmetic material feeding container 1 of the present embodiment, as described above, the rod-shaped cosmetic material M having an elliptical cross-section has gripping pieces 7 at four positions on the outer periphery except for the major axis and the minor axis. d is gripped from four sides, and is firmly gripped, and the gripping piece 7 d has a substantially fan-shaped cross-section, so that the gripping piece 7 d has a sufficient thickness, In addition, the advance / retreat hole 6 i in the cartridge cylinder 6 is formed close to the outer peripheral surface of the rod-shaped cosmetic material M, and the advance / retreat groove 6 p in the cartridge cylinder 6 approaches the outer peripheral surface of the gripping piece 7 d. As a result, the external force can be received by the entire cartridge cylinder 6, and the gripping piece 7d has a substantially fan-shaped cross section as well as the advance / retreat groove 6 in the cartridge cylinder 6. p is formed close to the outer peripheral surface of gripping piece 7d. Since you are, it has been eliminated that the gripping piece 7 d even if an external force acts gripping the stick-shaped cosmetic material M from falling inward.

Therefore, in the stick-shaped cosmetic material feeding container 1 of the present embodiment, the stick-shaped cosmetic material M is reliably prevented from breaking or coming off.

Further, in the present embodiment, as described above, the gripping piece 7 d for gripping the bar-shaped cosmetic material M having an elliptical cross-sectional shape has a base end portion of the rod-shaped cosmetic material M which is abutted against the elliptical cross-sectional shape. The base 7c is provided at four locations on the outer periphery except for the major axis and the minor axis, and has a substantially fan-shaped cross section, and the outer periphery of the gripping piece 7d faces the long axis in the cross section. And the forward and backward holes 6 i in the cartridge tube 6 are formed close to the outer peripheral surface of the rod-shaped cosmetic material M and the forward and backward grooves 6 p in the cartridge tube 6. Since it is formed close to the outer peripheral surface of 7d, it is unnecessary to provide a flat cutout at the base end of the rod-shaped cosmetic material M. The cartridge tube 6 to be accommodated is made smaller in the radial direction. Therefore, in the stick-shaped cosmetic feed container 1 of the present embodiment, the manufacturing cost is reduced and the container 1 is downsized without making the stick-shaped cosmetic M brittle.

Further, in the present embodiment, as described above, the gripping piece 7 d has a substantially fan-shaped cross section, and the advance / retreat groove 6 p in the cartridge cylinder 6 is close to the outer peripheral surface of the gripping piece 7 d. Since they are formed in a similar shape, even if the gripping piece 7 d is tilted inward during assembly, the gripping piece 7 d must be inserted into the approximately same shape advance / retreat groove 6 p in the cartridge cylinder 6. Thus, the gripping piece 7d is corrected according to the advance / retreat groove 6p, and is normally opened, so that it is easy to attach the stick-shaped cosmetic to the gripping piece 7d.

Therefore, in the stick-shaped cosmetic dispensing container 1 of the present embodiment, the production cost is further reduced.

The most effective application to the stick-shaped cosmetic feed container 1 of the present embodiment is a stick-shaped cosmetic M having a particularly flat elliptical cross section, but the stick-shaped cosmetic has an elliptical shape. If it is thick, it may be thick.

As described above, the present invention has been specifically described based on the embodiment. However, the present invention is not limited to the above embodiment. For example, in the above embodiment, the rear end side of the cartridge storage container 3 The screw brush 4 is installed, but instead of this, a rod-shaped cosmetic cartridge equipped with a rod-shaped cosmetic with a different color or type from the rod-shaped cosmetic M on the tip side, or a liquid cosmetic cartridge is installed. It is also possible. Further, in the above embodiment, the outer peripheral surface 7y of the gripping piece 7d is a curved surface, but is not necessarily limited to a curved surface, and may be, for example, a flat surface. Further, in the above embodiment, as a most preferable form in consideration of easiness of assembly, replacement of the bar-shaped cosmetic material M, and the like, the force-removal configuration in which the rod-shaped cosmetic cartridge ² is detachable from the cartridge accommodating container 3 is provided. Of course, even if it is fixed to impossible, good. Industrial applicability

ADVANTAGE OF THE INVENTION According to this invention, while reducing the manufacturing cost and miniaturizing a container without making the bar-shaped cosmetics brittle, the bar-shaped cosmetics can be reliably broken and come off when an external force acts. The present invention provides a stick-shaped cosmetic dispensing container that can be prevented from being damaged and that the stick-shaped cosmetic can be easily attached and the production cost can be further reduced.
