2. Description of the Related Art FIG.
Is a prior application of the same applicant as this application (Japanese Patent Application No. 7-20734).
It is sectional drawing which shows the stick-shaped cosmetic material feeding container disclosed in 0). The left side shows the cartridge, and the right side shows the container body.

The cartridge 1'of the container shown in this figure is composed of four parts: a cartridge cylinder 11, a chuck 31, a tension spring 41 and a stopper member 46. The cartridge cylinder 11 has a hollow cylindrical shape, and the upper end thereof is a tip opening 13 through which a stick-shaped decorative material (not shown) comes in and out.
The inner diameter of the tip opening 13 is slightly larger than the outer diameter of the stick-shaped decorative material, and supports and guides the stick-shaped decorative material in the lateral direction. The diameter of the inner hole 12 of the cartridge cylinder 11 is slightly larger than the outer diameter of the chuck 31, so that the chuck 31 can slide smoothly in the axial direction.

On the inner surface of the cartridge cylinder 11, 180 °
Two vertical grooves 21 facing each other are cut in a straight line in the vertical direction. The butt (projection) 35 of the chuck 31 fits in the vertical groove 21 and slides vertically. As a result, the chuck 31 linearly moves in the cartridge cylinder 11 to prevent the tension spring 41 from twisting and the stick-shaped cosmetic material from rotating. The vertical groove 21 is provided so as to extend from slightly below the front end port 13 to the spring rear end locking surface 19 in the cartridge cylinder rear end direction. The number of such vertical grooves may be one, or three or more.

The lower portion (rear end side) of the inner hole 12 of the cartridge cylinder 11 has a large diameter. A portion where the diameter is large is a step portion, and a rear end portion 45 (a portion having a large diameter) of the extension spring 41 is provided on an end surface (spring rear end locking surface 19) of the step portion.
The upper end surface of the abuts. From the bottom of the cartridge cylinder 11
A stopper member 46 is attached to about 3 parts. The stopper member 46 is mounted in such a manner that a stopper inner protrusion 48 provided on the inner side of the stopper member 46 protrudes into the vertical groove 21 from a hole 47 penetrating the side wall of the cartridge cylinder 11.

5A and 5B are views showing a stopper member of the cartridge of FIG. 4, wherein FIG. 5A is a front view and FIG. 5B is a side sectional view. The stopper member 46 is a ring-shaped member having a C-shaped cross section as shown in FIG. The C-shaped cut (slit 49) can be elastically deformed so as to be opened, and the cartridge cylinder 11 (shown by the one-dot chain line) can be covered.
On the inner surface of the stopper member 46, the stopper inner protrusion 48
, Which are opposite to each other by 180 ° and project inward. The inner protrusion 48 serves as a stopper with which the chuck abuts.

On the other hand, the cartridge cylinder 11 shown in FIG.
An opening (a hole 47 to the extent that the protrusion 48 inside the stopper protrudes inward) is formed in the portion where the cross section of the stopper member 48 is shown.
Has been opened. In addition, the periphery of the opening on the outer periphery of the cartridge cylinder 11 is a recessed portion that is dug in one step. The state of FIGS. 4 and 5 shows that the stopper member 46 is fitted into the recess while the C-shaped cut of the stopper member 46 is opened (while being elastically deformed). Further, a connecting projection 25 for connecting to the container body is provided on the middle portion of the outer surface of the cartridge cylinder 11. Furthermore, the projection 2
An O-ring 26 is attached to the bottom of the No. 5.

The chuck 31 is generally in the shape of a cylinder with a bottom, and the rear end portion of the stick-shaped decorative material is inserted and supported in the cavity portion 33 on the inner surface on the upper side of the drawing. A cylindrical spring tip locking portion 37 is provided below the chuck 31 so as to hang downward. A spring locking projection 39 projects from the outer circumference of the spring tip locking portion 37, and the spring wire of the pulling spring 41 pushed into the locking portion 37 is locked to the chuck 31.

A rear end portion 45 of the tension spring 41 (lower end of the drawing)
Is larger than the other parts. The upper end surface of the same portion contacts the spring rear end locking surface 19 of the cartridge cylinder 11 and is fixed in the upward direction. The pulling spring 41 extends between a spring front end portion 43 that is locked to the chuck and a spring rear end portion 45 that contacts the cartridge cylinder.

The inner surface of the rear end of the cartridge cylinder 11 has a diameter larger than that of the inner hole 12 in which the chuck 31 slides. In this portion, a knurled synchronous engagement groove 2 is formed.
3 is cut to extend vertically. This groove 23
The cartridge cylinder 1 engages with a synchronous engagement rib 165 provided on the outer diameter of the female screw member 161 on the container body side, which will be described later.
1 rotates in synchronization with the female screw member 161.

Shown on the right side of FIG. 4 is a sectional view showing the internal structure of the container body in which the cartridge is mounted. The container body 150 of the stick-shaped cosmetic material feeding container is composed of a container cylinder 151, a female screw member 161, a push rod 171, a brush (assembly) 178, a cap 180, a C ring 195, and a push spring 201. Container cylinder 15
Reference numeral 1 denotes a hollow cylindrical shape, and a tip portion (upper portion) thereof is a connecting portion 153 opened upward. Near the upper end of the connecting portion 153, a connecting concave portion 154 that is concave in a ring shape is cut. The above-mentioned connecting protrusion 25 on the outer surface of the cartridge cylinder is fitted into this, and the cartridge and the container body are connected.

The container cylinder 151 has a substantially simple cylindrical shape. Four vertical grooves 152 are cut in the lower half of the inner surface of the container cylinder so as to extend vertically, facing each other by 90 °. A butt 177 on the outer surface of the push rod rear end flange 175 is vertically slidably fitted into the vertical groove 152 so that the push rod 171 and the container cylinder 151 rotate in synchronization.

A brush holder 179 is fitted to the rear end of the container cylinder 151. The brush 178 is used by a user of the cosmetic material to blur, for example, an eye line or the like. A cap 180 is attached to the outside of the brush 178. Brush holder 179 and container tube 151
Are provided with an annular convex portion 215 (on the holder side) and an annular concave portion 213 (on the container cylinder side).

The female screw member 161 incorporated in the container body 150 has a cylindrical shape. Female thread member 1
Two spiral grooves 163 are cut in the inner hole surface of 61.
The number of spiral grooves may be one or more. A group of projections 173 on the outer surface of the push rod 171 are engaged with the spiral groove 163, and both form a mechanism similar to the combination of the female screw and the male screw. On the outer surface of the female screw member 161, four synchronous engaging ribs 165 extending in the vertical direction are cut. When the cartridge is mounted on the container body, the ribs 165 enter into and engage with the synchronous engagement groove 23 on the inner surface of the lower portion of the cartridge barrel 11, and the cartridge barrel rotates in synchronization with the female screw member 161.

The push spring 201 is housed between the upper surface of the rear end flange 175 of the push rod 171 and the lower surface of the flange portion 213 of the inner hole of the container cylinder so as to surround the push rod, and pushes between both surfaces freely. The push rod is biased in the backward direction. Because of the spring 201, when the cartridge is removed from the container body and the rotation of the female screw member 161 becomes free, the push rod automatically returns straight (without rotation) from the extended position to the most retracted position. Therefore, when replacing the cartridge,
The push rod is always at the rearmost position, so that the rod-shaped cosmetic material is not carelessly fed out when a new cartridge is mounted, and damage to the rod-shaped cosmetic material can be prevented. In addition, since the push rod and the container cylinder do not relatively rotate during the auto return, no torsional force acts on the spring 201, and a smooth movement can be obtained.

The final retracted position of the push rod 171 is determined by the lower end surface of the C-shaped ring 195 fitted in the tip end portion of the push rod 171 contacting the upper end surface of the female screw member 161. The C-shaped ring 195 has a C shape in which a part of the ring is cut away. The C-shaped ring 195 is fitted with a C-shaped notch widened in a ring groove cut on the outer periphery of the push rod 171. The C-shaped ring 195 is fed out into the cartridge cylinder at the tip of the push rod. When the lower end surface of the C-shaped ring 195 comes into contact with the upper end surface of the female screw member 161, the push rod cannot be further retracted.

The role of the O-ring 26 on the outer surface of the cartridge 1'is to provide a constant rotational resistance between the cartridge cylinder 11 and the container cylinder 151. If this rotation resistance does not exist, the pushing rod 1 and the spring 201 will urge the push rod 1
71, the female screw member 161, and the cartridge cylinder 11 idle, and the push rod naturally returns to the last retracted position.

A part of the lower portion of the push rod 171 of the container body 150 is a flat portion 211 having a cylindrical surface without a group of protrusions 173. The diameter of the flat portion 211 is the same as the diameter of the cylindrical shaft at the portion where the group of projections 173 is provided. The flat portion 211 comes to a position where it is fitted with the female screw member 161 when the push rod 171 is at the forward (up) limit. Therefore, in this state, even if the cartridge and the container main body are relatively rotated, the female screw member 161 and the push rod 171 idle. Further, since the push rod 171 is biased in the backward direction by the push spring 201 and the pulling spring 41 of the cartridge, when the idle rotation occurs, the push rod projection 1
When 73 enters or exits the spiral groove 163, a clicking sound is heard. By this idling, the user can clearly feel that the stick-shaped decorative material has reached the limit of feeding.

[0019]

The above-mentioned cartridge type stick-shaped cosmetic material feeding container has a number of excellent characteristics. However, expanding the C-shaped stopper member and mounting it on the cartridge is a little troublesome. Further, since the cartridge is sold by itself, the product name and lot number are often printed on the side surface of the cartridge, but the stopper member becomes a hindrance when printing. Further, depending on the manufacturer of the cosmetic product, since the tip end portion of the cartridge is decorated by vapor deposition or the like, it is easier to work if only the tip end portion is a separate body. Also,
When changing the thickness of the container body, it is cheaper to make the mold cost by separating only the tip portion of the cartridge.

An object of the present invention is to provide a cartridge for a stick-shaped cosmetic material feeding container, which is easy to manufacture and assemble and which is also suitable for printing or decorating the surface.

[0021]

In order to solve the above-mentioned problems, the cartridge of the stick-shaped cosmetic material feeding container of the present invention is a cartridge which is detachably attached to the end of the container body having a push rod which can be fed in the axial direction. A cartridge cylinder having an inner hole for advancing and retracting the stick-shaped cosmetic material, and a chuck for supporting the rear end of the stick-shaped cosmetic material and moving forward and backward in the inner hole of the cartridge cylinder driven by the push rod, The cartridge cylinder body includes a first cylinder body including a tip opening through which a stick-shaped cosmetic material comes in and out, and a chuck stopper projecting into the inner hole and abutting against the chuck to define a retreat limit thereof. The second cylinder is a plastic injection molded body, and the chuck stopper is inserted into the inner hole of the second cylinder from the front and the rear. Characterized in that it has been formed by the pin of the tip.

A cartridge for a stick-shaped cosmetic material feeding container according to another aspect of the present invention is a cartridge detachably attached to the tip of a container body provided with a push rod that can be drawn in the axial direction; A cartridge cylinder having an inner hole for advancing and retreating; and a chuck for supporting the rear end portion of the bar-shaped decorative material and for moving forward and backward in the inner hole of the cartridge cylinder by being driven by the push rod. A body, a first tubular body including a tip opening through which a rod-shaped decorative material comes in and out; and a second tubular body including a chuck stopper that projects into the inner hole and abuts the chuck to define a retreat limit thereof. It has a mating structure, and the contact portion of the chuck with the chuck stopper can bend in the axial center direction (inside). When inserting the chuck into the cylinder from the rear end of the cylinder, the contact part can bend inside and pass through the chuck stopper part.

[0023]

DETAILED DESCRIPTION OF THE INVENTION A description will be given below with reference to the drawings. FIG. 1 is a sectional view showing the structure of a cartridge of a stick-shaped cosmetic material feeding container according to an embodiment of the present invention. FIG.
FIG. 2 is a side sectional view showing a state in which a cartridge cylinder of the stick-shaped cosmetic material feeding container of FIG. 1 is disassembled. Portions similar to those of the cartridge of the stick-shaped cosmetic material feeding container in FIG. 4 are denoted by the same reference numerals. The first characteristic of the cartridge of the stick-shaped cosmetic material feeding container of the present embodiment is that the cartridge cylinder 2 has a structure in which the first cylinder 3 on the outside of the front end and the second cylinder 4 on the inside of the rear end are combined. That is. The first cylinder 3 constitutes the cartridge cylinder 2 by itself from the tip opening 13 to the step 51. The inner diameter of the tip opening 13 is a dimension obtained by adding a slight gap to the outer diameter (2.0 mm in one example) of the stick-shaped decorative material 5 (2.2 mm in one example). Support in the radial direction.

The inner diameter of the first cylindrical body 3 increases from the front end port 13 toward the rear end. The inner diameter of the first cylindrical body 3 at the step portion 51 is 4.6 mm in this example. From the stepped portion 51 to the container body contact stepped portion 57 which is the rear end of the first tubular body 3, two tubular bodies, an outer first tubular body 4 and an inner second tubular body 4, are provided. It is a fitted double structure. The inner peripheral surface of the rear end portion of the first cylindrical body 3 and the second cylindrical body 4 in contact with this surface
A knurl 53 and a locking unevenness 55 are formed on the outer peripheral surface of the. As shown in FIG. 2, the knurls 53 include vertical ribs 53 b on the outer circumference of the second tubular body 4 and the first tubular body 3.
It is a combination of the vertical grooves 53a on the inner periphery of the first cylinder body 3 and prevents the first cylinder body 3 and the second cylinder body 4 from being displaced in the rotational direction. Locking unevenness 5
Reference numeral 5 is a combination of an annular concave portion 55a and a convex portion 55b, which prevents axial displacement between the first cylinder 3 and the second cylinder 4. Due to the knurls 53 and the locking concavities and convexities 55, the first cylinder body 3 and the second cylinder body 4 become a cartridge cylinder 2 similar to an integrated body. In terms of appearance, since the joint between the two cylinders is the corner of the container main body abutment step 57, the two cylinders look like an integrated body, and the user does not feel uncomfortable. There is no problem even if it does not look like a one-piece object.

The second characteristic of the cartridge for the stick-shaped cosmetic material feeding container shown in FIG. 1 is that the stopper member 46 in the cartridge for the stick-shaped cosmetic material feeding container shown in FIG. 3 does not exist. Instead, as a chuck stopper, a stopper inner protrusion 59 that protrudes into the inner hole of the second cylindrical body 4 (bottom of the vertical groove 21) is formed. Stopper protrusion 48
Has a slope (bottom side 1.5 in this example) on the rear end side (lower side in the figure).
mm, height 0.45 mm), and the tip side is a surface perpendicular to the inner hole surface. This is because the butt 60 of the chuck, which will be described later, is easy to insert and does not come off.

The second cylindrical body is a plastic injection molded body, and the chuck stopper is molded by the tip of the core pin inserted into the inner hole of the second cylindrical body from the front. That is, at the time of injection molding of the second cylindrical body 4, the front end side core pin reaching from the front end side inner hole 52 of the second cylindrical body 4 to the upper surface of the stopper inner protrusion 59 and the rear end side engagement groove 12 are formed.
Two rear end side core pins reaching from the portion 3 to the slope of the lower surface of the stopper inner protrusion 48 are placed in the injection molding die. The upper surface of the stopper inner protrusion 48 is formed by the lower end surface of the tip side core pin, and the lower surface is formed by the upper surface of the rear end side core pin.

The reason why such molding is possible is that the inner hole at the tip end side of the second tubular body 4 is a straight hole (diameter 3.1 mm, vertical groove bottom gap 4.6 mm). The hole diameter of 3.1 mm is a size obtained by adding a sliding clearance to the outer diameter of the chuck 31 of 3.0 mm. The outer diameter of the chuck 31 is 3.0 mm, which is the outer diameter of the rod-shaped decorative material 5 of 2.0 mm plus the thickness of the chuck 31. On the other hand, the diameter of the distal end inner hole 13 of the first cylindrical body 3 is, as described above, the stick-shaped decorative material 5
An outer diameter of 2.0 mm, plus sliding clearance of 0.1 mm × both sides = 2.2 mm. That is, the inner hole diameter (3.1 mm) of the second cylindrical body 4 is about twice the thickness of the chuck as compared with the diameter (2.2 mm) of the distal end inner hole 13 of the first cylindrical body 3. There is no choice but to grow. Therefore, if the cartridge cylinder 2 is made as an integral injection-molded product and the stopper inner projection 59 is formed to project on the cylinder inner surface, the molding core pin between the tip inner hole 13 and the stopper inner projection 59 is undercut. Therefore, injection molding becomes impossible.
Therefore, as in the present embodiment, the cartridge cylinder 2 is divided into the first cylinder 3 and the second cylinder 4, and the tip inner hole 13 is formed in the first cylinder and the second cylinder 4 is formed. The stopper inner protrusion 59 is formed.

The third characteristic of the cartridge of the stick-shaped cosmetic material feeding container shown in FIG. 1 is the bend structure of the chuck. That is, the contact portion between the chuck and the chuck stopper in the chuck has a structure capable of bending in the axial center direction (inside), and when the chuck is inserted into the cylinder body from the rear end of the cylinder body when the cartridge is assembled. The contact portion can bend inside and pass through the chuck stopper portion, and after passing through the chuck stopper portion, the contact portion returns to its original shape to prevent the chuck from retracting. FIG. 3 is a side view of a chuck used in the cartridge of the stick-shaped cosmetic material feeding container of FIG. 1. The chuck 31 of FIG. 3 has a coil spring-shaped decorative material support portion 32, and a tail portion of a stick-shaped decorative material is inserted and held in an inner hole 33 of the decorative material support portion 32. The distal end (upper end) of the decorative material support portion 32 is flat, and a taper 32 is provided on the inner surface. Therefore, it is easy to put cosmetic materials. Since the coil spring-shaped decorative material supporting portion 32 elastically supports the stick-shaped decorative material, it helps prevent the stick-shaped decorative material from being broken.

A bat 60 is formed on the outer surface of the center of the chuck 31.
Are provided so as to project outward. The side surface of this butt engages with the vertical groove (21 in FIG. 1) of the inner hole of the cartridge in which this chuck 31 is mounted. The upper surface of the bat 60 is an inclined surface, and the lower surface is a surface perpendicular to the axial direction. As shown in FIG. 1, the lower surface of the butt 60 has a stopper inner protrusion 59 of the inner hole of the cartridge cylinder 2.
The upper surface of the chuck 31 comes into contact with the upper surface to prevent the chuck 31 from coming off.

Left and right bats 60, 60 'of the chuck 31
A bend hole 62 having a large hole is provided between them. Therefore, when a force that sandwiches the left and right bats 60, 60 'is applied, the parts on both sides of the bend hole 36 are bent toward the center side, and the left and right bats 60, 60' are moved toward the center. ing. This is because when the chuck 31 is installed in the cartridge cylinder 2 of FIG. 1 (pushed from the bottom into the inside of the cartridge hole 2 from above), the butt 60 projects into the cartridge cylinder 2 inside hole. This is for facilitating passage through the protrusion 59. But,
After passing once, the bat 60 returns to its original form (projects to the outside), and when the chuck attempts to retract, the lower surface of the bat 60 and the upper surface of the stopper inner protrusion 59 come into contact with each other, and Prevent retreat. Since both of the abutting surfaces are surfaces (surfaces that are not inclined) perpendicular to the retreat direction of the chuck, the abutting force of this surface does not act on the bend structure of the chuck, and the butt 60 may move inward. There is no such thing.

An outer surface of the chuck 31 on the tail end side (lower side in the drawing) is a spring locking portion 37. In the spring locking portion 37,
Pull spring for automatic return of chuck 31 (4 in FIG. 1)
1) is locked. Two spring locking protrusions 39 provided on the same portion 37 are for hooking and stopping the spring wire of the pulling spring. The slit 38 between the two spring locking projections 39, 39 'is opened by penetrating the spring locking portion 37 like a window. Because of the slit 37, if the protrusions 39 and 39 'are pinched with fingers when the spring is attached, the distance between the protrusions is narrowed and the spring wire can be easily passed. A push rod (171 in FIG. 4) on the main body side of the stick-shaped cosmetic material feeding container comes into contact with the tail end of the chuck 31, and the chuck 31
Also, the stick-shaped cosmetic material is moved back and forth.

A method of assembling the cartridge shown in FIG. 1 will be described collectively. First, the spring wire on the tip side of the pulling spring 41 is pushed into the spring locking portion 37 of the chuck 31, and the spring locking projection 39 is passed over to assemble the chuck 31 and the pulling spring 41.

Next, the assembly of the chuck 31 and the spring 41 is pushed in from the inner hole on the rear end side of the second cylindrical body 4 (from the bottom of FIG. 1) in the form of FIG. At this time, the rear end of the chuck 31 is pushed by a thin rod. When pushed in, the upper surface of the butt 60 of the chuck 31 that has entered the inner hole of the cartridge cylinder 2 contacts the lower surface of the stopper inner protrusion 59, but both surfaces are slopes that are easy to climb and the bat 60 has a bend hole. Because of the presence of 62, the butt 60 of the chuck 31 rides over the stopper inner protrusion 59 so that the bat 60 projects above the stopper inner protrusion 59. Then, since the lower surface of the bat 60 and the upper surface of the stopper inner protrusion 59 face each other and face each other, the chuck 31 cannot come out. At this time, the rear end portion 45 (large diameter portion) of the spring 41 contacts the spring rear end locking surface 19 of the cartridge cylinder bore, the spring 41 is slightly tensioned, and the core chuck is always in tension. Fixed by.

Next, the tip end of the second cylinder 4 is inserted into the first cylinder 3 to assemble the cartridge cylinder 2. At this time, the cylindrical bodies 3 and 4 are fixed in the circumferential direction and the axial direction by the action of the knurled portion 53 and the locking concave and convex portion 55. This completes the assembly of the cartridge. The first cylinder and the second cylinder may be assembled first, and then the chuck may be inserted into the second cylinder. However, the assembled second cylinder is stocked as a unit and various shapes, colors, decorations,
In terms of actual production, it is more preferable to assemble the first cylinder in the printed state according to the customer's order.

[0035]

As compared with the cartridge of Japanese Patent Application No. 7-207340, the chuck stopper does not use the C-shaped member, so that the assembly is easy. Also, the cartridge rear part (inner cylinder part)
It is easy to print lot numbers and product names such as eyeliner and eyebrow. By changing the color of the first cylinder and the second cylinder,
The product number (eyebrow, eyeliner, etc.) can be identified. For the above reason, the decoration of vapor deposition or the like may be applied to the first cylindrical body only by the first cylindrical body, and the axis for masking or the like is not required. When the unit method is used, only the unit can be manufactured and in stock, and the thin and shape of the container (square or non-circular shape)
The change of can be done only by exchanging the mold of the first cylinder, and various specifications can be reasonably supported. The lead chuck is locked to the chuck stopper simply by inserting it from the rear part of the second tubular body. At that time, it is pulled by a pulling spring and kept in a tensioned state. Therefore, the core is easily held and assembled easily.
