Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for feeding a stick-shaped cosmetic material (lipstick, eyeliner, etc.). In particular, by using a hollow push rod that has a group of projections that function as male threads on the outer surface and also has a rotation stopper on the inner surface, a female thread member with high manufacturing cost (a tubular member having a spiral groove on the inner surface)
The present invention relates to a stick-shaped cosmetic material feeding container that can be shortened in length and is also suitable for reducing the diameter.

[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. 8 is a sectional view showing the internal structure of the cartridge type stick-shaped cosmetic material feeding container disclosed in Japanese Utility Model Laid-Open No. 2-1018. In this delivery container, when the cartridge 210 is inserted from the insertion opening 252 of the container body 250, the tail plug 246 of the cartridge 210 is attached to the shaft rod substrate 256.
And is held by the elastic holding body 270 of the rotation holding member 260. During this time, the shaft rod 258 penetrates the through hole 244 of the tail plug 246 and enters the deepest portion in the fitting insertion hole 240 of the push rod 234.

In this state, the tip of the cartridge 210 protruding from the container body 250 is gripped to hold the container body 25.
When 0 is rotated, the push rod 234 is swung along the screw groove 230 via the shaft rod 258 and moves forward while compressing the coil spring 242, and the tip of the push rod 234 pushes the cosmetic material holding member 228 to remove the cosmetic material 212. It is paid out from the opening 214. When the container body 250 is rotated in the reverse direction, the push rod 234 rotates in the reverse direction and is forcibly swung back along the screw groove 230,
The cosmetic holding member 228 and the cosmetic 212 are drawn in by the engaging protrusion 236.

When the cartridge 210 is detached from the container body 250 with the cosmetic 212 being dispensed, the push rod 23
4 is disengaged from the shaft rod 258, the push rod 234 becomes rotatable, and the push rod 234 is forcibly retracted while rotating along the screw groove 230 by the repulsive force of the compressed coil spring 242. As a result, the cosmetic 212 will be naturally drawn in.

In the cartridge type stick-shaped cosmetic material feeding container of the invention No. 2-1018 devised, the rotation preventing shaft bar 258 of the container body side is inserted into the push rod 234 to prevent the push rod from rotating, and the coil spring 242 for automatic return is used. It is characterized by the clever inclusion of. Therefore, it has an advantage that the total length of the container can be shortened.

[0007]

However, the actual Kaihei 2-1.
The cartridge type stick-shaped cosmetic material feeding container of the invention has the following problems. In the inner diameter of the lower half of the cartridge main body 218, it is necessary to provide a long thread groove 230 corresponding to the stroke of the feeding container. Therefore, this cartridge body 218
It took a lot of time to mold, process and mold.

Due to restrictions in molding / processing (for example, strength / processing of the injection-molded core pin), the diameter of the thread groove 230 cannot be reduced, and therefore the entire container cannot be reduced in diameter. When the cartridge is removed from the container body, the core chuck is always located at the lower limit due to the urging force of the spring, so that it is impossible to make a difference between the cartridges alone (stick-shaped cosmetic material). Therefore, it has been necessary to set the cartridge in the container and raise the cosmetic material chuck to the upper end and then carry out the red color difference.

It is an object of the present invention to provide a stick-shaped cosmetic material feeding container suitable for reducing the diameter of a container without using a long female threaded component or a long male threaded component which is difficult to manufacture and costly. Another object of one aspect of the present invention is to provide a stick-shaped cosmetic material feeding container capable of producing a reddish color with a single cartridge.

[0010]

In order to solve the above-mentioned problems, a stick-shaped cosmetic material feeding container of the present invention has a chuck for supporting the stick-shaped cosmetic material, a tip opening through which the stick-shaped cosmetic material goes in and out, and the chuck is a shaft. A chuck guide cylinder having an inner hole for slidably guiding in a direction, a female screw member having an inner surface with a spiral groove cut, connected to the chuck guide cylinder, and a push rod axially connected to the chuck. An outer surface provided with a group of projections screwed into the spiral groove,
And a hollow push rod which also has a synchronous engaging hole extending in the axial direction in the shaft core portion, and a detent rod which is non-rotatably and slidably inserted in the axial engaging hole; It is characterized in that the hollow push rod is advanced and retracted by relatively rotating the member and the detent rod.

[0011]

The group of protrusions on the outer surface of the push rod is screwed into the spiral groove of the female screw member, and when the push rod and the female screw member rotate relative to each other (for example, either one fixes one and the other rotates). Moves in a spiral groove along the spiral groove while making a relatively spiral movement. As the protrusion moves, the push rod is pulled out and pulled in from the female screw member.

In the stick-shaped cosmetic material feeding container of the present invention,
The shaft core portion of the push rod is a synchronous engagement hole extending in the axial direction, and a detent rod is inserted into this hole so as to be non-rotatable and slidable in the axial direction. When the anti-rotation rod and the female screw member are relatively rotated, the hollow push rod and the female screw member are relatively rotated, and the hollow push rod advances and retracts in the axial direction while maintaining the synchronous engagement with the anti-rotation rod. As a result, the chuck that is slidably housed in the chuck guide cylinder and that is axially connected to the push rod is advanced and retracted, and thus the stick-shaped cosmetic material supported by the chuck is drawn out and retracted.

Here, the synchronous rotation or the non-rotatability means that the hollow push rod and the detent rod (in other combinations) rotate substantially in synchronization. For example, it is a state in which the synchronous engagement rib of the detent bar moves straight in the axial direction in the synchronous engagement groove cut straight in the synchronous engagement hole of the hollow push rod in the axial direction. However, the synchronous engagement groove may be slightly spiral as long as the relative rotation between the hollow push rod and the female screw portion is not hindered. Further, it may be rotated by a certain amount of play (gap). The shape of the detent may also be ribs, grooves, protrusions, triangles, squares, stars, and the like.

In the stick-shaped cosmetic material feeding container of the present invention,
The spiral body provided on the outer surface of the push rod is a group of protrusions arranged so as to occupy a part of a virtual spiral space wound around the outer surface of the push rod so as to be screwed into the spiral groove of the female screw member. If you try to make a push rod with a male thread on the outer periphery by injection molding using a split mold, there are severe restrictions on the diameter and pitch of the screw in order to prevent undercuts during die cutting, and you must use screws with a short pitch. I can't. Therefore, there was a problem in the operability of the feeding mechanism, but in the spiral body composed of this group of protrusions,
There is no problem of undercut, and the pitch of various spirals can be freely selected.

In the conventional screw-type feeding mechanism, a screw having a certain cross-sectional shape is continuously cut. This is because it was considered natural due to the general common sense of screws and the limitation of the manufacturing method of obtaining screws by cutting machining. However, upon careful consideration, it is almost the case that, in many feeding mechanisms, it is not necessary that the screws having a certain cross-sectional shape be continuously connected. A "screw" may be formed by intermittently arranging a group of protrusions having an appropriate shape at a required position of such a virtual continuous screw. In that case, depending on the grouping (selection) of a group of protrusions, the pitch and leads of these protrusions can be freely selected to some extent. In addition, if a group of protrusions aligned in the axial direction is selected, a lead infinite screw (spline) is obtained.

The female screw member of the present invention is connected to the chuck guide cylinder. Of course, both may be directly connected, or some members / parts may exist between them and may be indirectly connected. Note that such a relationship between parts (possibility of interposition of an intermediate part) also applies to another relationship between other parts in the present invention.

The chuck according to the present invention broadly means the entire holding member that holds the rear end of the stick-shaped decorative material and can feed and pull the same. In addition, "providing A with B", such as "providing a chuck stopper on the chuck guide tube", or "providing" with "A provided on B", etc., also applies when A and B are integrated. , A is formed separately from B, and the case where the separate body is assembled with B is also broadly included.

In the stick-shaped cosmetic material feeding container of the present invention,
The chuck guide cylinder and the female screw member may be configured as an integral body or fixed to each other. For example, both may be integrated into a plastic injection-molded product, or only the chuck guide tube may be an aluminum pipe to pursue design. When the stick-shaped decorative material is paid out / pulled in, the rotation of the female screw member can be stopped or rotated by pinching or turning the chuck guide cylinder.

In the stick-shaped cosmetic material feeding container of the present invention,
It is also possible that the rotation stopping rod has an insertion rod portion that is inserted into the synchronous engagement hole of the hollow push rod and a flange portion that is fixed to the rear end portion (the end portion on the opposite side of the insertion side) of the insertion rod portion. Good. When unwinding or retracting the stick-shaped cosmetic material, you can operate the detent bar by gripping the flange that is easy to grip.

In the stick-shaped cosmetic material feeding container of the present invention,
The chuck guide cylinder and the female screw member are configured as an integral body or fixed to each other, and the chuck guide cylinder and the hollow push rod connected to the chuck are combined to form a cartridge; The rod has an insertion rod portion that is inserted into the synchronous engagement hole of the hollow push rod, and the detent rod and the container cylinder form a container body; the outer peripheral portion of the female screw member or the chuck guide cylinder is the container cylinder. The cartridge is mounted on the container body by inserting the insertion rod part of the rotation stop rod into the synchronous engaging hole of the hollow push rod and rotating the chuck guide cylinder and the container cylinder relative to each other after mounting. By doing so, the hollow push rod can be configured to advance and retract. Such an embodiment is a so-called cartridge type delivery container.

In the stick-shaped cosmetic material feeding container of this aspect, a spring for urging the hollow push rod in the backward direction is provided in the cartridge, and the cartridge and the container body relatively rotate and slide. A rotary friction member may be provided in the portion, and when the cartridge is detached from the container body and the rotary friction between them is released, the hollow push rod may automatically return to the retracted position.

The outer peripheral surfaces of the cartridge tip cylinder 11 and the female screw member 41 are inserted and assembled. A leaf spring 57 is provided on the lower inner surface of the cap insertion portion 55 of the container cylinder 51 so as to stick to the inner surface. The leaf spring 57 elastically clamps the outer circumference of the female screw member 41 to give a certain pullout / rotation resistance. The central portion of the leaf spring 57 is a leaf spring step portion 59, which fits in the annular engaging groove 48 of the female screw member 41 to position the cartridge in the axial direction (longitudinal direction) with respect to the container body. Further, the user can be informed that the cartridge mounting is completed by an engagement feeling and a clicking sound when the leaf spring step portion 59 fits in the annular engagement groove 48, and a pleasant feeling is given.

The rotation stopping rod 61 is composed of an insertion rod portion 65 and a flange portion 68, and is shaped like an insect pin. 4A and 4B are diagrams showing a rotation-stop rod, FIG. 4A is a side view, and FIG. 4B is a cross-sectional view of an insertion rod portion. As shown in FIG. 1, the insertion rod portion 65 of the rotation stop rod 61 is inserted into the synchronous engagement hole 35 of the hollow push rod 31. Also,
The outer periphery 69 of the flange portion 68 of the rotation stopping rod 61 is fixed to the inner surface of the rear end portion of the container cylinder 51.

As shown in FIG. 4, the insertion rod portion 65 of the rotation preventing rod 61 is in the shape of a round rod, and four synchronous engaging ribs 67 extending in the axial direction are provided on the outer surface at 90 ° distribution. It is provided. The synchronous engagement rib 67 enters the synchronous engagement groove 37 (see FIG. 2B) of the synchronous engagement hole 35 of the hollow push rod, and the detent rod 61 and the hollow push rod 37 rotate synchronously. The synchronous engagement rib 67 and the synchronous engagement groove 37 are slidable in the axial direction, and the axial insertion depth of the detent rod 61 and the hollow push rod 31 in accordance with the extension of the hollow push rod 31. Changes.

The flange portion 68 of the whirl-stop rod 61 is provided integrally with the insertion rod portion 61. The outer periphery 69 of the flange portion 68 is fixed to the inner surface of the lower portion of the container cylinder 51 with an adhesive or the like. The flange portion 68 is a container cylinder 51.
Also plays the role of a tail plug that closes the bottom end of the. Further, it is possible to widen the variation of the usage form as a stick-shaped cosmetic material feeding container by providing a hollow portion on the lower end surface of the flange portion 68 and attaching a brush or a sponge tip to the hollow portion.

Each part of the stick-shaped cosmetic material feeding container of this embodiment can be manufactured, for example, by the following materials and manufacturing methods. Cap: Deep drawing of aluminum Cartridge barrel: Aluminum pipe or deep drawing Integrated chuck / hollow push rod: Plastic (POM, A
BS, etc.) Injection molding Female thread member: Same as above Non-rotating rod: Same as above Container tube: Aluminum pipe Leaf spring: Stainless steel

An example of the feeding operation in the feeding container of this embodiment will be described. The cap 1 is removed from the stick-shaped cosmetic material feeding container, and the outer surface of the cartridge tip cylinder 11 is pinched and fixed with the finger of the left hand. At the same time, the container cylinder 51 is rotated while pinching the outer surface of the container cylinder 51 with the finger of the right hand. Then, the whirl-stop rod 61 rotates integrally with the container cylinder 51, and the hollow push rod 31 synchronously engaged therewith also rotates. On the other hand, the female screw member 41 screwed to the hollow push rod 31 is fixed to the cartridge tip cylinder 11 and fixed by the finger of the user's left hand. Therefore, relative rotation occurs between the hollow push rod 31 and the female screw member 41, and the hollow push rod 31 is fed out from the female screw member 41 according to the same principle as the combination of the male screw and the female screw. Naturally, the chuck 21 and the stick-shaped decorative material 3 are also fed out in association with the hollow push rod 31.

FIG. 5 is an exploded sectional view of a stick-shaped cosmetic material feeding container according to another embodiment of the present invention. This stick-shaped cosmetic material feeding container also includes the cap 1, the cartridge tip cylinder 11, the chuck 21, the hollow push rod 31, the female screw member 41, the container cylinder 51,
It is made up of parts such as the whirl-stop rod 61. The detent rod 61 engages with a synchronous engagement hole (not shown) in the hollow push rod 31 as in the embodiment of FIG.

The features of the stick-shaped cosmetic material feeding container shown in FIG. 5 will be described. First, the spring 87 that biases the hollow push rod 31 in the backward direction is incorporated in the rotary hook 49 of the female screw member 41. The spring 87 surrounds the outer circumference of the hollow push rod 31. The upper end of the spring 87 is in contact with the step (spring receiving surface 85) at the rear end of the female screw portion 44 of the female screw member 41. The lower end of the spring 87 is in contact with the upper surface of the spring retainer 91. The spring retainer 91 is a C-shaped ring-shaped member, and is fitted into a retainer groove cut on the outer surface of the lower end of the hollow push rod 31 so that the C-shaped opening is widened.

The spring 87 biases the hollow push rod 31 freely through the spring retainer 91. Therefore, if the cartridge is pulled out from the container cylinder 51 and the detents between the detent rod 61 and the hollow push rod 31 are disengaged while the hollow push rod 31 is being fed out, the hollow push rod 31 is rotated to the most retracted position. Therefore, when the cartridge is replaced, the hollow push rod is always in the last retracted position, and when a new cartridge is installed, the stick-shaped cosmetic material does not inadvertently come out and the stick-shaped cosmetic material is destroyed. It can be prevented. In addition, since the cosmetic material is drawn in just by pulling out the cartridge from the container body, the user is
There is no need to put back the cosmetic material one by one.

A 0 ring groove 83 is cut on the outer circumference of the female screw member 41, and a 0 ring 81 is fitted therein. The role of the O-ring is to give a certain rotation resistance between the container cylinder 51 and the female screw member 41 (integrated with the cartridge cylinder 11). If this rotation resistance does not exist, the urging force of the spring 87 causes the hollow push rod 31, the rotation-stopping rod 61, and the container cylinder 51 to rotate integrally, and the hollow push rod naturally returns to the final retracted position. Become. In addition, the container cylinder 51
The female screw member and the hook portion 49 are locked by an annular convex portion 105 and an annular concave portion 95 provided at the lower ends of the female screw member and the hook portion 49 so as not to shift in the axial direction.

In the stick-shaped cosmetic material feeding container of the embodiment shown in FIG. 5, the cartridge tip cylinder 11, the female screw member 41, and the hook portion 49 of the female screw member are a long integrated product (plastic injection molded product). This is preferable in reducing the number of parts. The uppermost portion (the tip portion of the cartridge tip cylinder 11) and the lowermost portion (female screw member hook portion 49) of this integrated product
At the rear end), annular recesses 79 and 95 are cut on the inner surface. The concave portion 79 elastically engages with the annular convex portion 73 on the outer surface of the locking collar 71 that hangs on the lower surface of the top plate of the cap 1.
Further, the annular concave portion 95 elastically engages with the annular convex portion 105 on the outer surface of the locking collar 103 protrudingly provided on the upper surface of the flange portion 68 at the lower end of the rotation preventing rod 61. As a result, even when the cap 1 is mounted on the cartridge tip cylinder 11 or when the cartridge is mounted on the container cylinder 51, both the concavities and convexities engage with each other at the final stage of mounting, so that a comfortable mounting feeling can be obtained.

The upper end portion of the container cylinder 51 is a step portion 101, and this step portion 101 is fitted with the step portion 77 at the lower end portion of the cap 1. Flange portion 68 of non-rotating rod 61 and container cylinder 5
No. 1 is fixed by the locking unevenness 107. The group of projections 33 on the outer surface of the hollow push rod 31 of this embodiment are provided at two positions at the same height and facing each other by 180 °. These projections 33 are screwed into the two spiral grooves 45 cut on the inner surface of the female screw member 41.

FIG. 6 is a sectional view of a cartridge of a stick-shaped cosmetic material feeding container according to another embodiment of the present invention. In this embodiment, the vertical groove 1 is formed on the inner surface of the cartridge tip cylinder 11.
10 is cut so as to extend in the axial direction. This flute 1
A butt (projection) 111 on the outer surface of the chuck 21 enters the chuck 10 and slides up and down. Therefore, the chuck 21
Slides vertically with respect to the cartridge tip cylinder 11. In this container, the front end of the cartridge front cylinder 11 is inclined, and the front end of the stick-shaped cosmetic material accommodated in the front cylinder 11 is also inclined accordingly. In such a case, it is not good if the tip cylinder 11 and the bar-shaped decorative material rotate relatively. Therefore, as described above, the chuck 21 is made to slide straight up and down in the inside of the front cylinder 11.

In this embodiment, the chuck 21 and the hollow push rod 31 are separate members, and they are rotatably connected by dovetail-shaped circular concave-convex portions 113 and 115. The circular recess 113 is provided so as to engrave the lower surface of the chuck 21. The recess 113 is formed so as to widen toward the back of the recess. The circular convex portion 115 is provided so as to project on the tip surface of the hollow push rod 31. This convex portion 115
Is increasing in diameter from the root to the front. When both the concave and convex portions are combined, the head of the convex portion first interferes with the entrance of the concave portion, but the elastic deformation of both portions allows the head of the convex portion to be pushed into the concave portion. After that, both are rotatably connected. As a result, the rotation caused by the feeding of the hollow push rod 31 is cut off by the uneven portion and is not transmitted to the chuck 21.

At the lower end of the hollow push rod 31 of this embodiment, a spring retainer portion 117 is formed integrally with the hollow push rod. The spring retainer portion 117 extends from the lower end portion of the hollow push rod 31 to the left and right in the figure, and the spring 8 is provided on the upper surface of the portion 117.
The lower end of 7 abuts. A method of assembling this cartridge will be described. First, the spring 87 is inserted outside the hollow push rod 31 from the upper end side. Next, the female screw member 41 is attached to the hollow push rod 3
Attach it by screwing it into 1. Further, the hollow push rod 31
Push the chuck 21 into the upper end. In this state, an adhesive is applied to the outer circumference of the female screw member 41. The above-described assembly is assembled into the cartridge tip cylinder 11 (the female screw member 4 so as to surround the outside of the spring 87).
(It also extends below 1) and is assembled into the cartridge cylinder so that the vertical groove 110 of the cartridge cylinder and the butt 111 of the chuck are aligned. The method of fixing the female screw member 41 and the cartridge tip cylinder 11 may be fitting and fixing of concave and convex or press fitting.

FIG. 7 is a sectional view showing an example of a female screw member having a pocket portion for locking the hollow push rod backward. The upper end of the spiral groove 45 of the female screw member 41 is provided with a pocket portion 119 that is connected to the spiral groove 45 and extends laterally. In this pocket portion 119, the hollow push rod 31
The bottommost protrusion 33-L on the outer surface is introduced as follows.
That is, at the position where the hollow push rod 31 is extended to the vicinity of the forward limit, the protrusion 33-L is 33-L- in the spiral groove 45.
From the position a (slightly ahead of the forward limit) to 33-LB (reaching the forward limit), the female screw member 41 and the hollow push rod 31 are further advanced.
By relatively rotating and, the protrusion 33-L advances into the pocket 119 (position 33-L-c).

When the protrusion 33-L enters the pocket portion 119, the protrusion 33-L contacts the lower wall of the pocket portion 119. Therefore, even if the hollow push rod 31 is pushed backward,
Does not retreat. On the other hand, when the protrusion 33-L is in the spiral groove 45, the protrusion 33-L slides in the spiral groove 45,
The hollow push rod 31 retreats while rotating. That is, since the pocket portion 119 is provided, the hollow push rod 31 is locked at the forward limit position.

When the stick-shaped cosmetic material is inserted into the chuck 21 after the stick-shaped cosmetic material feeding container is assembled, when the base portion of the stick-shaped cosmetic material is pushed into the chuck 21, the hollow push rod and the chuck are pushed by the backward force applied to the hollow push rod 31. It is difficult to insert the stick-shaped cosmetic material into the chuck if it retreats (enters) into the chuck guide cylinder. This is even more so when there is a spring that biases the hollow push rod in the backward direction. At this time, if the backward movement of the hollow push rod is locked by the pocket portion, the work of inserting the stick-shaped decorative material into the chuck can be performed easily. Further, if there is an auto return spring, the protrusion 33
-If L is rotated until it comes out of the pocket portion 119, the stick-shaped cosmetic material will automatically return to the final retracted position by itself, which further facilitates the work.

The pocket portion may be provided not on the female screw member but on the upper portion of the female screw member. Further, the lock position does not have to be strictly at the maximum forward limit as long as it is a position where the stick-shaped decorative material can be inserted. On the contrary, when the lead angle of the screw is large (when there is no spring 87), red will appear unless the lower limit lock of the lead chuck is made (transportation, vibration, etc.). In that case, conversely, 34L at the bottom of the female screw
By providing a pocket such as -c, it is possible to prevent the scarlet from appearing. In addition, in the case of the stick-shaped cosmetic material feeding container of this embodiment, a sleeve (a component with slits in the chuck sliding portion), which is used in a conventional general container, is not required, so the diameter of the container can be made smaller.

FIG. 9 is a sectional view showing a stick-shaped cosmetic material feeding container according to another modification of the present invention. This stick-shaped cosmetic material feeding container has a chuck 21 for supporting the stick-shaped cosmetic material, a tip opening for letting the stick-shaped cosmetic material come in and out, and a chuck guide cylinder 11 having an inner hole for guiding the chuck axially slidably.
And a female screw member 41 connected to the chuck guide cylinder 11 and having an inner surface with a spiral groove cut, and the chuck 11
And a group of projections 133 screwed into the spiral groove are arranged on the outer surface of the push rod 131 in the axial direction of the push rod 131 substantially linearly.
And a detent pipe 135 having a synchronous engagement hole formed with a synchronous engagement groove 137 that is non-rotatably and axially slidably engaged with the group of protrusions 133; It is characterized in that the push rod 131 is moved forward and backward by rotating the anti-rotation pipe 135 relatively.

The stick-shaped cosmetic material feeding container of FIG. 9 is different from the stick-shaped cosmetic material feeding container of the other embodiments in that the push rod 131 (not necessarily hollow) is prevented from rotating (synchronous engagement with the container body 51). Is performed by engaging the protrusion 133 on the outer surface of the push rod 131 and the synchronous engagement groove 137 on the inner surface of the rotation preventing pipe 135. Although such a configuration is somewhat disadvantageous from the viewpoint of reducing the diameter of the container body, the purpose of omitting the long female screw component or the long male screw component can be achieved.

As is apparent from the above description, the stick-shaped cosmetic material feeding container of the present invention exhibits the following effects. Manufacturing costs can be reduced because long internal threaded parts that require manufacturing costs are unnecessary. The diameter of the container can be reduced because long internal threaded parts that are difficult to reduce in diameter due to manufacturing are unnecessary. Hollow push rods with various pitch and lead spiral functions can be manufactured with high efficiency by split mold injection molding. In the embodiment in which the female screw member is provided with the pocket portion for preventing the hollow push rod from retracting, the work of inserting the stick-shaped decorative material into the chuck can be easily performed even before the cartridge and the container body are assembled.
