Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cartridge for a stick-shaped cosmetic material feeding container. More specifically, the present invention relates to a cartridge of the above container, which is useful for effectively reducing the diameter of the cartridge, reducing the number of parts, and preventing damage to the stick-shaped cosmetic material in the cartridge by effectively using a pulling spring and a chuck stopper.

[0002]

2. Description of the Related Art There are two types of delivery containers for stick-shaped cosmetic materials, those of cartridge type and those of non-cartridge type. In a cartridge type container, a core material (hereinafter referred to as a cosmetic material) having a different color is built in each cartridge, and the cosmetic material such as eyebrow of a desired color can be obtained by appropriately replacing the cartridge body with the container body and mounting the cartridge body. Can be used.

FIG. 13 is a sectional view showing the structure of a cosmetic material container cartridge having a tension spring for a lead chuck auto return, which is disclosed in Japanese Utility Model Publication No. 3-31232. A core chuck 205 is slidably housed in the main body 202 of the cartridge 201 in the vertical direction in the drawing.
A holding projection 207 is provided on the lower surface of the lead chuck 205, and the projection 207 has a constricted portion 208 and a spring locking step 208. The extension spring 210 includes a small diameter portion 210b, a main body portion 210a, and a large diameter portion 210c from the top to the bottom of the drawing.
It is composed of three parts. Of these, the upper small diameter portion 210b is fitted on the outer surface of the holding protrusion 207 of the lead chuck 205. The large diameter portion 210c at the lower portion abuts the step portion 202a at the lower end of the cartridge body 202 and is regulated from below by the tail plug 204 so as not to escape from the cartridge body.

When the lead chuck 205 is pushed upward from below by being pushed by a push rod (not shown), the stick-shaped decorative material (not shown) held by the lead chuck is transferred to the cartridge body 20.
It is fed out from the tip end of No.2. When the push rod descends, the core chuck 205 is pulled by the tension spring 210 and descends, and the stick-shaped decorative material is retracted. When the cartridge 201 is removed from the container body, the push rod is pulled out from the inner hole of the cartridge body 202. Therefore, the tension spring 210 is left in a free state, and the escape of the spring is suppressed by the tail plug 204.
The advantage of the tension spring type cartridge is that the diameter of the cartridge can be reduced and the number of parts can be reduced as compared with the case where the protective cylinder is wound around the stick-shaped decorative material and the push spring is provided outside the protective cylinder.

[0005]

[Problems to be Solved by the Invention] Actual fairness 3-31232
In the No. 1 cartridge, the tension spring becomes free when the push rod is separated from the core chuck. At this time, if the cartridge is exposed to inadvertent movement, the tension spring, the core chuck, and the stick-shaped decorative material will dance in the cartridge body in the axial direction and the radial direction. If this happens, the soft cosmetic material may be scratched or broken, rendering it unusable or degrading its commercial value. Since the cartridge of the cosmetic container is often distributed and sold separately from the container main body, or detached from the container main body and carried by the consumer, such a risk is considerably great. Also, with the cartridge of the same invention,
The tail spring that prevents the spring, the chuck, and the stick-shaped cosmetic material from slipping out from the rear end of the cartridge body is required.

According to the present invention, the number of parts can be reduced, the diameter of the cartridge can be reduced by using the pulling spring, and the damage of the stick-shaped cosmetic material can be suppressed. The purpose is to provide.

[0007]

In order to solve the above-mentioned problems, a cartridge of a stick-shaped cosmetic material feeding container of the present invention is detachably attached to the tip of a container body having a push rod that can be fed in the axial direction. A cartridge for a stick-shaped cosmetic material feeding container capable of paying out a stick-shaped cosmetic material in accordance with the movement of a push rod, and a cylinder having a tip opening through which the stick-shaped cosmetic material comes in and out, and slidably accommodated in the cylinder body. And a chuck for supporting the rod-shaped decorative material pushed by the push rod and advancing toward the tip of the cylinder, and a tension spring for engaging the chuck and urging the chuck toward the rear end of the cylinder. A cylindrical stopper is provided with a chuck stopper that defines the retreat limit of the chuck.

[0008]

The push rod can be drawn out from the container body by a screw mechanism or the like. The cartridge is attached to the tip of the container body by fitting and the push rod is extended. Then, the stick-shaped cosmetic material is fed out from the tip end opening of the cartridge cylinder in accordance with the movement of the push-rod such that the tip of the push-rod enters the cartridge inner hole and pushes the chuck supporting the stick-shaped cosmetic material. When retracting the stick-shaped cosmetic material, when the push rod is retracted to the container body side, the chuck is biased by the pulling spring toward the rear end of the cylinder, so the chuck and the chuck are supported by it as the push rod retracts. The stick-shaped cosmetic material is also drawn into the cartridge. Since the retreat limit of the chuck is set by the chuck stopper provided in the cylindrical body, the chuck and the pulling spring engaging with the chuck will not come out of the cylindrical body even if there is no tail plug of the cylindrical body.

In a preferred aspect of the present invention, the chuck is located at the retreat limit even when the cartridge is detached from the container body, and the length of the tension spring is appropriately selected so that the tension spring can be moved in the above state. It is possible to keep them nervous. Since the conventional cartridge does not have a chuck stopper, as long as the tension spring is tensioned, the chuck abuts the push rod and retracts, but the chuck retracts until the tension spring becomes free. Then the chuck stops at that position. However,
Since the cartridge of the present invention is provided with a chuck stopper, by properly selecting the length of the tension spring, the tension spring is kept in tension even when the chuck is in contact with the stopper and is in the retracted limit. be able to.

In a preferred aspect of the present invention, the tubular body is provided with a spring rear end engaging portion for engaging the rear end portion of the pulling spring so as not to move in the distal direction of the tubular body at least. The chuck is provided with a spring tip locking portion that locks the tip portion of the pulling spring, and the front and rear end portions of the pulling spring have a shape capable of locking the locking portions. ing.

It is sufficient to give tension to the tension spring if the rear end of the tension spring is at least immovable in the direction of the tip of the cylinder. Of course, you may make it not move to the rear end direction of a cylinder. As a method of locking the spring, hook the wire of the spring on the protrusion, hook the wire on a hole or hook, bond with an adhesive, heat the plastic parts to soften them. There are various methods such as pressing a spring, but the present invention is not limited to a particular method.
The fact that the tip portion of the tension spring has a shape capable of being locked with the locking portion means that the shape is suitable for the locking method as in the above example. The tip of the spring means near the tip of the spring (in the direction of the tip opening of the cylindrical body in the assembled state), and does not refer only to the tip surface or the strict tip of the spring. The same applies to the rear end of the spring.

[0012] In a preferred aspect of the present invention, the chuck stopper is a bend stopper having an inner protrusion protruding from an inner surface of the cylindrical body, and the chuck is inserted into the cylindrical body from a rear end of the cylindrical body during assembly. In this case, the stopper can be bent outward to pass the chuck,
After the passage, the stopper returns to its original form and prevents the chuck from moving backward by bringing the chuck or the pulling spring into contact with the inner protrusion. According to this aspect, it is possible to provide a cartridge having a simple structure and easy to assemble.

Here, "passing through the chuck" does not necessarily mean passing through the entire chuck.
When a part of the chuck comes into contact with the stopper to prevent the chuck from retracting, the stopper may spring back after the part of the chuck has passed. Also,
When a part of the tension spring held by the chuck comes into contact with the stopper to prevent the chuck from retreating, it is understood that a part of the tension spring is a part of the chuck. The stopper must spring back after passing. "Abutment of stopper and chuck or tension spring"
As for the above, the former two may directly contact with the latter, or some members / parts may exist between them to indirectly contact with each other. Note that such a relationship between parts (possibility of interposition of intermediate parts) also applies to another relationship between other parts in this specification.

In a preferred aspect of the present invention, the chuck stopper is a bend stopper having an outer protrusion protruding from the outer surface of the cylinder, and the chuck is inserted into the cylinder from the rear end of the cylinder during assembly. In this case, the stopper does not project into the cylinder and can pass through the chuck. After the passage, the stopper pushing member is attached to the outer surface of the cylinder, so that the stopper bends inward and the inside of the cylinder is stopped. A part of the chuck protrudes, and the chuck or the pulling spring is brought into contact with the projected part to prevent the chuck from retracting. In this aspect, since the stopper does not project into the cylindrical body during assembly, it is easy to assemble. Further, there is no possibility that the stick-shaped decorative material will come into contact with the inner protrusion of the stopper and be damaged. Here, "passing through the chuck" has the same meaning as described above.

In a preferred aspect of the present invention, the bend stopper is formed by cutting out a part of the cylindrical body. Since the stopper does not have to be a separate component, the component manufacturing cost and assembly cost can be kept low.

In a preferred aspect of the present invention, a protrusion is provided on a part of the outer surface of the chuck, and a storage groove for accommodating the protrusion is provided on the inner surface of the cylinder so as to extend in the axial direction. The chuck stopper engages with the protrusion to define the retreat limit of the chuck, and the stopper is provided in the storage groove so as not to substantially project outside the groove.

Since the stopper does not substantially project outside the groove of the cartridge cylinder, harmful contact between the stopper and the stick-shaped decorative material can be prevented. "Substantially not projecting" means that even if the stopper is protruding from the groove to the extent that it is not harmful (lightly pushed and retracted), it is allowed in the present invention.

In a preferred aspect of the present invention, a first large diameter portion is provided at the rear end portion of the tension spring, and an end surface of the first large diameter portion abuts on the tubular body. As a result, a spring rear end locking surface that locks the large-diameter portion so as not to move toward the distal end of the cylinder is provided, and the chuck has a spring locking protrusion that locks the distal end of the pulling spring. Is provided,
A second large diameter portion that engages with the spring locking protrusion of the chuck is provided at the tip end portion of the tension spring. According to this aspect,
The tension spring can be securely and easily locked between the tubular body and the chuck. Other methods may be used for the shape of the tension spring and the method of engaging with the chuck / cylindrical body. For example, the shape and engagement method of the extension spring such as the above-mentioned Japanese Utility Model Publication No. 3-31232 may be applied to the present invention.

In a preferred aspect of the present invention, in addition to the tubular body, the chuck and the extension spring, a spring locking body is further provided, and the spring locking body is locked to the tubular body,
Further, the spring locking body has a tubular shape, and the pulling spring is housed therein, and the spring locking body is provided with a rear end portion of the pulling spring in at least a tip direction of the tubular body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will now be described with reference to the drawings. FIG. 1 is a view showing a cartridge of a stick-shaped cosmetic material feeding container according to an embodiment of the present invention. The chuck is in the retracted limit, (A) is a cross-sectional view, and (B) is a side view of the cartridge of (A) as viewed in the BB direction. The cartridge 1 basically includes a cartridge cylinder 11 and a chuck 2.
It is composed of three parts, 1 and a spring 31. The cartridge cylinder 11 has an elongated cylindrical shape, and has a front end opening 13 at a front end (upper end in the drawing) and a rear end opening 14 at a rear end (lower end in the drawing). The stick-shaped decorative material 5 contained in the cartridge 1 goes in and out through the tip opening 13. Tip opening 1
The inner diameter of 3 is a dimension obtained by adding the necessary clearance to the outer diameter of the stick-shaped decorative material 5. The rear end opening 14 is provided with a rear end locking surface 19 (details will be described later) of the pull spring.
In addition, a chuck stopper 16 (details will be described later) having an inner protrusion 17 that protrudes to the inner surface of the cylinder is provided at the bottom of the cylinder.

The chuck 21 has a cylindrical shape with a bottom, and is housed in the cartridge cylinder 11 so as to be slidable in the axial direction (vertical direction in the drawing). FIG. 2 is a diagram showing details of the chuck of the cartridge of FIG. 1, (A) being a sectional view,
(B) is a side view. The inside of the chuck 21 is a concave cavity 23, into which the rear end of the stick-shaped decorative material is inserted and held. The rib 25 has a function of more firmly holding the stick-shaped decorative material on the chuck. A chuck slit 29 is formed in the side wall of the chuck 21 so that the side wall of the chuck can be easily expanded when the rear end of the stick-shaped cosmetic material is inserted, and when the excessive force is applied, the stick-shaped bar is formed. The decorative material is hard to break.

On the lower surface of the bottom of the chuck 21, a ring-shaped spring tip locking portion 27 is provided upright.
A spring locking protrusion 28 is provided on the lower end of the outer surface of the protrusion 7. The tip portion 33 of the pulling spring 31 is fitted to the locking portion 27, the wire of the spring is hooked on the spring locking projection 28, and the tip of the spring is locked to the chuck.

The extension spring 31 includes a spring tip portion 33 fitted to the chuck 21, a spring intermediate portion 37 having a smaller diameter than the spring tip portion 33,
It is composed of a spring rear end portion 35 having a larger diameter than the spring front end portion 33. FIG. 3 is a cross-sectional view showing details of the extension spring of the cartridge of FIG.

The rear end portion 35 of the pulling spring 31 is in contact with the upper end surface of a stepped spring rear end locking surface 19 provided inside the rear end opening 14 of the cartridge cylinder 11. The portion of the rear end port 14 has a larger diameter than the portion of the inner surface of the cartridge cylinder 11 on which the chuck 21 slides. In this way, the spring rear end portion 35 is positioned so as not to move in the front end direction of the cartridge cylinder 11 (upward in the drawing).

The lower end surface of the tip end portion 33 of the tension spring 31 is in contact with the upper end portion of the inner protrusion 17 of the chuck stopper 16, and the tension spring 31 and the chuck 21 are further retracted (downward in the drawing). It does not move). The upper end surface of the stopper inner protrusion 17 may be the chuck 21 in some cases.
Of the chuck 2 by contacting the lower end surface of the spring tip locking portion 27 of
Block the retreat of 1.

In this embodiment, the chuck stopper 16 is formed integrally with the cartridge cylinder 11. As shown in FIG. 1 (B), the stopper 16 is formed in a shape like a tongue in which a part of the side wall of the cartridge cylinder 11 is cut off by a slit 18 on three sides. The upper portion of the stopper 16 is slightly thicker than the side wall of the cartridge cylinder 11, and the inner side of the upper portion is an inner protrusion 17 that protrudes into the cartridge cylinder 11. The inner profile of the stopper 16 has a rounded (circular) chamfer at the upper end, and the top of the rounded portion projects the most inward, forming a gentle slope from the top to the original inner surface of the cylinder. I am joining.

The tongue-shaped chuck stopper can be bent (bent) from the root of the tongue by appropriately selecting the material and size. When the chuck 21 is inserted into the cylinder from the rear end opening 14 of the cartridge cylinder 11, the upper end of the chuck 21 pushes the inner protrusion 17 of the stopper 16 outward to bend the stopper outward, and the inner protrusion 17 outward. By pushing, the chuck 21 can be inserted onto the stopper 16. After the chuck 21 has passed the stopper portion, the stopper 16 springs back due to elasticity, and the inner protruding portion 17 returns to the original state.
The inner surface of the chuck 1 is brought into contact with the lower surface of the chuck or the lower end surface of the spring tip 33 to contact with the upper surface of the same to prevent the chuck from retreating.

The cartridge cylinder 11 and the chuck 21 are generally manufactured by injection molding of plastic.
The slit on the side wall of the cartridge cylinder 11 is formed by a U-shaped pin inserted from the side toward the center of the cylinder until it hits the core pin. The inner protrusion 17 of the stopper is formed by pouring plastic into a recess formed on the outer surface of the core of the mold, and when the core is pulled out, the entire stopper 16 bends outward so that the inner protrusion 17 moves from the inner surface. As it is retracted, the core is not undercut.

The tongue-shaped bend portion is not limited to the type provided so as to extend from the bottom to the top as shown in the figure, but the bend root may be upward and the bend may be extended downward. Further, the bend may be provided laterally (direction orthogonal to the axis of the cylinder). The shape of the bend portion is not limited to the rectangular shape, and may be a triangle, a trapezoid, a parallelogram, or a shape having a radius. It suffices if the above-mentioned purpose of the bend can be achieved and it is convenient for molding such as die cutting of the core pin.

FIG. 4 is a sectional view showing a cartridge of a stick-shaped cosmetic material feeding container according to another embodiment of the present invention. The feature of this cartridge is the tongue-shaped chuck stopper 1
The outer projecting portion 43 projecting outward from the outer surface of the cartridge barrel 11 is provided at the upper end portion of the cartridge 6. Since the chuck stopper 16 of this embodiment does not have the inner protrusion 17 unlike the stopper of FIG. 1, the chuck 21 can be smoothly inserted into the cartridge cylinder 11 from below. Further, even when the chuck is inserted with the stick-shaped decorative material mounted on the chuck 21, there is no undesired catch or contact between the stick-shaped decorative material and the inner surface of the stopper 16.

After inserting the chuck, the cartridge outer cylinder 4 as a stopper pushing member is provided on the outer surface of the cartridge cylinder 11.
When 1 is fitted, the outer protruding portion 43 of the chuck stopper 16 is pushed inward, and the stopper 16 bends inward, so that the inner upper end portion of the stopper 16 projects into the cartridge cylinder, and as in FIG. Will set the retreat limit of. As described above, the advantages of the cartridge of this embodiment are that it is easy to assemble and there is no risk of scratching the stick-shaped decorative material. Disadvantage is cartridge outer cylinder 41

The advantage of this cartridge is that the chuck 21
When the rod-shaped decorative material is inserted into the cartridge cylinder 11 with the rod-shaped decorative material attached thereto, the rod-shaped decorative material does not come into contact with the inner protruding portion 17 of the stopper, so that the rod-shaped decorative material can be prevented from being damaged. FIG. 6 is a view of the lower end of the cartridge cylinder 11 of FIG. 5 as viewed from below. As shown here, if a proper radius is attached to the inner edge of the storage groove 51,
It is also possible to prevent the occurrence of streaks due to the contact between the edge and the stick-shaped decorative material. Further, since the protrusion 53 of the chuck 21 is guided by the storage groove 51 of the cartridge cylinder 11 and the chuck slides straight on the cylinder, it is possible to prevent twisting of the tension spring 31 and accidental damage of the stick-shaped cosmetic material.

On the inner surface of the rear end of the cartridge cylinder of this embodiment, there is provided a ridge-shaped inner surface ridge 59. The inner surface protrusions 59 engage with the rotation preventing ribs 103 on the outer surface of the rotation preventing member 101 on the container body side, and play a role of preventing rotation of the push rod 91. Here, the "rotation stop" means to prevent the relative rotation of the cartridge cylinder 11 and the push rod 91, that is, to rotate both of them synchronously. Note that the internal / external relationship of the rotation preventing portion may be opposite to that of this embodiment. Further, the shape of the rotation stopper is not limited to the rib, and may be any shape as long as it plays the role of the rotation stopper, such as a protrusion and a combination of non-circular male and female. The detent structure may be of a type in which detent engagement portions are provided at the rear end of the chuck and the tip of the push rod as shown in FIGS.

On the other hand, on the inner surface of the inner cylinder 81, a female screw 83 that is screwed with the male screw 93 is cut over the entire length of the inner cylinder. A ridge is cut on the outer surface of the inner cylinder 81, and a groove cut on the inner surface of the outer cylinder 71 engages with this ridge, and the inner cylinder and the outer cylinder rotate integrally with each other. To do.

When the cartridge 1 is inserted from the rear end into the opening 73 at the tip of the container body 3, the outer diameter of the cartridge cylinder 11 is held by the elastic pressing force of the leaf spring 75 provided on the inner surface of the container outer cylinder 71. It The inner surface protrusion 59 at the rear end of the cartridge cylinder engages with the rotation preventing rib 101 on the outer circumference of the rotation preventing member 101 inside the container body as described above. Here, an engagement protrusion 105 is provided on the inner peripheral portion of the rotation preventing member 101, and this protrusion engages with the engagement groove 95 of the push rod 91. In this state, the cartridge cylinder 11 is pinched and fixed by the finger of the left hand, and the outer cylinder 71 of the container body 3 is rotated by the finger of the right hand, the cartridge cylinder 71, the inner surface protrusion 59, the rotation preventing member 101, the push rod 91 and the male screw. 93 does not rotate, while
The container outer cylinder 71, the container inner cylinder 81 and the female screw 83 rotate integrally. Therefore, the push rod 91 is paid out by the female screw 93.

The push spring 85 biases the push rod 91 toward the rear end. When the cartridge 1 is removed from the container body 3, the push rod 91 is free to rotate and the push rod 91 retracts while rotating (automatic return). When the cartridge 1 is attached to the container body 3, the push rod 91 does not automatically return even if the hand is removed from the container due to the frictional force due to the compression of the leaf spring 75. When the cartridge is removed, the push rod always automatically returns to the retracted limit, so that when the cartridge is attached next, the stick-shaped cosmetic material is prevented from being carelessly drawn out, and damage to the stick-shaped cosmetic material can be prevented.

The chuck 21 cannot normally retract further. That is, the spring locking body 111 defines the retreat limit of the chuck 21. Note that, unlike the state shown in this figure, a part of the pulling spring may contact the spring locking body 111 to determine the retreat limit of the chuck.

A rotation stopper 119 is provided on the outer periphery of the lower end portion of the spring locking body 111. As in the case of FIG. 5, the rib 119 engages with the detent member on the container body side to serve as a detent for the push rod 91 (synchronous rotation with the cartridge cylinder 11).

FIG. 9 is a sectional view showing a cartridge of a stick-shaped cosmetic material feeding container according to another embodiment of the present invention. FIG. 10 is a sectional view showing the outer cylinder 121 (A) and the inner cylinder 131 (B) of the cartridge of FIG. (C) is a view of the rear end of the outer cylinder from below, (D) is a view of the rear end of the inner cylinder from below,
(E) is a diagram of an EE cross section of the inner cylinder. The cartridge cylinder of this embodiment has a double structure of an outer cylinder 121 and an inner cylinder 131, and a spring locking inner step portion 1 is formed on the inner surface of the rear end portion of the inner cylinder 131.
The feature is that 41 is provided.

The cartridge outer cylinder 121 has a tip opening 12
3, an annular portion 125 on the inner surface of the lower portion of the mouth, a rotation stopping groove 127 extending in the axial direction on the inner surface, and an insertion portion 129 on the outer surface of the rear end portion. The cartridge inner cylinder 131 includes a tip opening 133, a step portion 134 on the outer surface of the lower portion of the same, and an annular convex portion 13 below the step portion 134.

From the rear end of the inner cylinder 131, the outer cylinder 12
1 is inserted into the outer cylinder 121 through the front end port 123 and assembled. In the assembled state, the step portion 134 of the inner cylinder abuts on the end surface of the front end port 123 of the outer cylinder. Further, the annular stepped portion 135 of the inner cylinder engages with the annular recess 125 of the outer cylinder to prevent it from coming off. The rotation stopper rib 137 of the inner cylinder enters the rotation prevention groove 127 of the outer cylinder to prevent the both cylinders from rotating relative to each other.

Before inserting the inner cylinder into the outer cylinder, the chuck 21 and the extension spring 31 are assembled in the inner cylinder 131. The assembling is performed by expanding the slit 129 at the rear end of the inner cylinder 131. The front end of the slit 139 extends in the cartridge cylinder front end direction beyond the step upper end 143 of the spring locking inner step, and the rear end of the slit penetrates to the rear end surface 145 of the inner cylinder 131. The inner diameter of the spring locking inner step portion 141 on the inner surface of the inner cylinder rear portion is usually smaller than the outer diameter of the chuck 21 and the outer diameter of the tip portion 33 of the pulling spring 31. However, if the slit 139 is expanded,
The inner step portion 141 can be expanded in inner diameter, and the chuck and the tension spring can be incorporated in the inner cylinder.

The lower end surface of the tip end portion 33 of the pulling spring 31 is in contact with the upper end 143 of the spring locking inner step portion 141 of the inner cylinder, thereby defining the retreat limit of the chuck 21.
The rear end portion 35 of the spring has its upper end surface abutted on the rear end surface 145 of the inner cylinder 131. As a result, the pulling spring 31 does not slip out of the cartridge cylinder without the tail plug or the like. Further, by selecting the free length of the tension spring intermediate portion 37 to be slightly shorter than the length of the spring locking inner step portion 141 of the inner cylinder, the cartridge is detached from the container body (the push rod contacts the chuck). Not), the tension spring can be kept in tension.

The lower end of the detent (female) 161 is open, and a detent rib 165 is provided on the inner wall of the detent hole 163 so as to extend in the axial direction. The chuck 151 is incorporated in a cartridge of the type shown in FIG. 5 so as to be axially slidable and biased rearward. When the cartridge is inserted into the holder 171 opening 173 of the container body 181, the chuck 1
The anti-rotation portion 193 at the tip of the push rod 191 completely fits into the anti-rotation hole 163 of 51. At this time, detent hole 1
The rib 165 in 63 and the detent rib 195 cut at the tip of the push rod engage with each other, and the chuck 151 and the push rod 19 are engaged.
It rotates synchronously with 1.

As shown in FIG. 5, the protrusion 152 protruding from the outer periphery of the chuck 151 engages with the storage groove 51 on the inner surface of the cartridge cylinder 11, so that the chuck 1
51 and the cartridge cylinder rotate synchronously. Therefore, the push rod 191 and the cartridge cylinder rotate synchronously, and the cartridge and the container body 181 or the holder 171 and the container body 181 that engage with the cartridge rotation stop spline 174 and rotate synchronously with the cartridge rotate relatively. Thus, the push rod 191 can be extended.

As for the male / female relationship of the chuck and the push rod to prevent detent, as in the chuck shown in FIG. 12, a detent (male) 167 having an outer peripheral detent rib 169 is provided on the chuck and the detent side is provided. It may be provided with a detent (female) having a hole or groove for engaging with this detent.

The group of protrusions are provided with a predetermined pitch and a circumferential angle, and function as a male screw. At the same time, the group of protrusions arranged straight in the axial direction can also serve as a rotation preventing rib. In this way, the projection group of the push rod exerts a plurality of functions depending on the group selection method.
A push spring 189 is wound around the push rod 191 and has the same action as the push spring 85 of the container body in FIG. The tail plug 190 defines the stroke end of the push rod 191 and prevents the internal parts of the container from coming off.

FIG. 14 is a sectional view showing a cartridge of a stick-shaped cosmetic material feeding container according to another embodiment of the present invention.
A chuck stopper 16 is provided below the cylindrical body 11 of the cartridge 1 of this embodiment, similarly to the cartridge of the embodiment shown in FIG.

The characteristics of the cartridge of the embodiment shown in FIG.
That is, the chuck stopper 16 is provided with the outer protruding portion 301. The outer protruding portion 301 is pushed by the inner surface 312 of the container body tip portion 311 when the cartridge 1 is mounted. As a result, the chuck stopper 16 bends inward. And when the installation is completed (Fig. 1
4 state), the outer protrusion 301 is spring-backed to the large diameter portion below the engagement step 313 on the inner surface of the container body. The user can comfortably feel the completion of cartridge mounting by the sound and feel at this time, and can also obtain a certain retaining effect.

FIG. 15 is a view showing a chuck of a cartridge of a stick-shaped cosmetic material feeding container according to another embodiment of the present invention. (A) is a sectional view (assembly state with a tension spring), (B)
Is a side view. A lower outer surface (cylindrical surface) of the chuck 321 serves as a spring tip locking portion 323. The spring tip locking portion 323 has two spring locking projections 325-1.
And 325-2 are projected. The cross-sectional shape of the spring locking protrusion 325 is a triangle that projects from bottom to top, as shown in FIG. Spring locking protrusion 32
The upper surface of 5 is substantially upright from the surface of the spring tip locking portion 323. In addition, two spring locking protrusions 325-1 and 32
5-2 is provided on the outer surface of the spring tip locking portion 323 so as to be divided by 180 ° and project from the upper and lower steps h. The spring locking protrusion 325 is shown in FIG.
As shown in (B), it has a flat triangular shape.

As shown in FIG. 15A, the upper end of the tension spring 331 is formed on the outer surface of the spring tip engaging portion 323.
It is inset. FIG. 16 is a perspective view showing the extension spring 331 of FIG. The extension spring 331 is a coil spring, and its lower portion (rear end portion 335) is a large diameter portion. The other parts of the tension spring 331 are parts having the same diameter. In addition, the inner diameter of the upper end portion (the portion that fits in the chuck) of the pulling spring 331 is equal to the spring tip locking portion 32 of the chuck 321.
3 is almost equal to the outer diameter.

A method of mounting the tension spring 331 of FIG. 16 on the chuck 321 of FIG. 15 will be described. First, the tip (upper part) of the pulling spring 331 is slightly pushed from the lower end of the spring tip locking portion 323 of the chuck 321 to the outer surface of the spring tip locking portion 323. At this time, since the taper 327 is attached to the lower end of the spring tip locking portion 323, the spring can be easily inserted. Next, while rotating the extension spring 331 in the positive screw direction (the chuck 321 may be rotated), the extension spring 3
The spring wire 333 at the tip of 31 is pressed against the spring locking protrusion 325-2 (the lower position). Then, the spring wire 333
Goes over the spring locking protrusion 325-2 and proceeds. Further, this operation is continued to connect the spring wire 333 to the spring locking projection 32.
Go over 5-1 and proceed. In this way, FIG.
As shown in (A), the chuck 321 and the extension spring 331 are assembled.

The step h between the upper spring locking projection 325-1 and the lower spring locking projection 325-2 is 1 / the spring pitch.
It is preferably 2 to 2 times and provided in accordance with the winding direction of the spring. This is because it is easy to assemble while rotating the spring. Further, the spring wire 333 has the spring locking protrusions 325-1 and 325-.
Since the spring wire is located between the spring wire and the locking projection, the spring wire and the locking projection do not overlap (the spring wire is positioned so as to ride on the outer surface of the projection). Therefore, the spring fits perfectly to the outer diameter of the chuck, and the movement of the chuck inside the cartridge cylinder becomes smoother.

FIG. 17 is a view showing a cylinder of a cartridge for a stick-shaped cosmetic material feeding container according to another embodiment of the present invention. (A) is a sectional view and (B) is a side view. A feature of this cartridge cylinder 341 is that it has a double-supported bend 345. The doubly supported bend 345 is attached to the cylinder 341 by
It is formed by cutting a parallel slit 346 (see FIG. 17B) in the book.

An inner protrusion 34 is formed on the inner surface side of the both-end bend 345.
7 is provided so as to project inward. The inner protrusion 347 abuts on a chuck (not shown) to define the retreat limit of the chuck. The outer surface of the both-ends bend 345 has a bow-like shape that is slightly curved inward. By doing so, the both-ends bend 345 has the following bend characteristics. Ie. Even if a slight force is applied to this bend outwardly, the bend is hard to bend. However, when the force in such a direction becomes larger than a certain value, Bend bends in an opposite manner with the bowstring.

Due to such bend characteristics, the bend bends when the core pin is pulled out during injection molding of the cartridge cylinder or when the chuck is inserted from below the cylinder into the cylinder. However, when the cartridge is removed from the container main body, the chuck is pulled by the tension spring and vigorously auto-returns, and the both-end bend 345 is not bent with a force such that the chuck hits the inner protrusion 347. Therefore, there is no fear that the chuck will accidentally fall off from the cylindrical body 341.

The cartridge cylinder 341 shown in FIG.
A ring groove 343 is also provided. The O-ring entering the groove 343 provides an appropriate sliding resistance between the cartridge and the container body. In addition, a roulette 349 is provided on the inner surface of the lower portion of the cylindrical body 341.

Further, an annular recess 353 is provided below the lowlet 349. This annular recess 353 is
It engages with the protrusion or the annular convex portion on the container body side and plays a role of preventing the cartridge from coming off. A taper 351 is attached to the lower end of the cylindrical body 341, which is outside the annular recess 353. The role of this taper 351 is as follows.
That is, when the above-mentioned annular recess is engaged with the protrusion of the container body or the like, the lower end portion of the tubular body 341 slightly expands, but this expansion allows the lower end portion of the tubular body to escape so as not to interfere with the inner surface of the container body. is there.

FIG. 18 is a view showing a cartridge of a stick-shaped cosmetic material feeding container according to another embodiment of the present invention. Figure 1
9 is a view showing a stopper member of the cartridge of FIG. 18, (A) is a front view, and (B) is a side sectional view. FIG. 20 is a side sectional view showing a modified example of the stopper member.

The cartridge shown in FIG. 18 is characterized in that the chuck stopper is formed as a stopper member 364 which is separate from the cartridge cylinder 361. The stopper member 364 has a cross-section C as shown in FIG.
It is a member in the shape of a letter ring. This C-shaped cut (slit 367) can be elastically deformed to open.

On the inner surface of the stopper member 364, stopper inner protrusions 365 project 180 ° opposite to each other by 180 °. The inner protrusion 365 serves as a stopper with which the chuck abuts. The position and shape of the protrusion inside the stopper are
It may be bilaterally symmetrical as shown in FIG. This makes it possible to assemble without worrying about the left / right (up / down) assembly posture.

On the other hand, in the cartridge cylinder 361 of FIG. 18, an opening (a hole through which the stopper inner protrusion 365 projects) is formed at the portion where the cross section of the stopper member 364 is shown. In addition, the periphery of the opening on the outer circumference of the cylindrical body 361 is a recessed portion that is dug in one step. While opening the C-shaped cut of the stopper member 364 in this recess (while elastically deforming), the stopper member 3
FIG. 18 shows the state in which 64 is fitted. In such a form, there is a disadvantage that the stopper member has to be a separate component, but there is an advantage that it looks good because a cut (slit) of the cylinder is not exposed on the outer surface of the cylinder.

[0077]

As is apparent from the above description, the cartridge of the stick-shaped cosmetic material feeding container of the present invention exhibits the following effects. The cartridge of the present invention, like the embodiment shown in FIGS. 1, 4, and 5, has a minimum of three parts (tube, chuck,
Spring). There is no need for a conventional tail plug or other spring drop prevention means. Therefore, manufacturing / assembling costs can be reduced.

Even after the cartridge is removed from the container body, the tension spring that biases the chuck rearward can be tensioned, so that the chuck is less likely to swing in the axial direction and the radial direction of the cartridge cylinder. In other words, the core is always upright. As a result, it is possible to prevent the stick-shaped decorative material supported by the chuck from being damaged. When the push spring is wound around the stick-shaped decorative material, a protection tube for the stick-shaped decorative material is required, and the diameter of the push spring is twice larger than the outer diameter of the stick-shaped decorative material. In the present invention, the outer diameter of the tension spring can be made equal to or less than the outer diameter of the bar-shaped decorative material.
Therefore, the outer diameter of the cartridge can be finally reduced.
