Description

The present invention relates to a stick-shaped cosmetic container for lipstick, lip gloss, lip balm, etc., and relates to a rod-shaped cosmetic delivery container that is friendly to the global environment.

Conventionally, in the case of stick-shaped cosmetic containers such as lipsticks, lip glosses, and lip balms, as a container that considers the global environment, the container itself is divided into a cartridge and a holder, and the cartridge-type stick-shaped cosmetics can be replaced. Feeding containers are known. In this cartridge-type stick-shaped cosmetics feeding container, when the stick-shaped cosmetics are used up, it is only necessary to dispose of the cartridge, and the amount of waste can be reduced (Reduction). Also, the holder could be used repeatedly (Reuse).

Moreover, the cartridge equipped with a feeding mechanism for feeding stick-shaped cosmetics could easily be diverted from the existing disposable type stick-shaped cosmetics feeding container. However, even though it can be diverted, if the cartridge itself can be used like a disposable feeding container (the cartridge alone can be used to carry up the stick-shaped cosmetics), the cartridge-type stick-shaped cosmetics feeding container is meaningless. It will disappear.

Therefore, the cartridges in Patent Document 1 and Patent Document 2 (cartridge A in Patent Document 1 and cartridge portion A in Patent Document 2) have a spiral groove (spiral strip 9, spiral groove 3) on the inner wall. The sleeve (sleeve 11, outer cylinder 1) and the holding cylinder (holding cylinder 2, middle plate 6) holding the stick-shaped cosmetics (stick-shaped cosmetics 1, cosmetics 5) are slidably rotated up and down. It has a built-in rotary feeding mechanism that feeds out stick-shaped cosmetics by relatively rotating the body cylinder (guide cylinder 4, inner cylinder 2) that is held impossible, but the lower end of the sleeve (sleeve 11, outer cylinder 1) is the body. It covers the cylinder (guide cylinder 4, inner cylinder 2), and the cartridge (cartridge A, cartridge portion A) alone cannot be used for feeding.

Further, in Patent Document 1, a pipe shape having a round hole (engagement hole 7) provided at the bottom of the body cylinder (guide cylinder 4) is formed, and the holder (holder B) is inserted into the round hole (engagement hole 7). A connecting piece (engagement cylinder 21) provided with a possible connecting cylinder (engagement cylinder 21), and a connecting piece (engagement cylinder 21) that elastically contacts and holds the inner wall surface of the round hole (engagement hole 7) on the side surface of the connecting cylinder (engagement cylinder 21). The spring piece 20) was provided, and the rotation of the holder (holder B) was transmitted to the body cylinder (guide cylinder 4) by the elastic holding force of the connecting piece (spring piece 20).

Further, in Patent Document 2, a hexagonal hole (non-circular fitting hole 8) is provided on the bottom surface of the body cylinder (inner cylinder 2), and the hexagonal hole (non-circular fitting hole 8) is provided in the holder (operation unit B). A connecting cylinder (projection 7) that has a similar shape to 8) and can be inserted is provided, and the connecting cylinder (projection 7) engages with the hexagonal hole (non-circular fitting hole 8) of the holder (operation unit B) to form the holder (projection 7).

In a general stick-shaped cosmetics feeding container, members exposed to the outside are molded from a metal material with excellent decorativeness and strength, and internal structural members such as a feeding mechanism are molded from a synthetic resin material with excellent moldability. It was common to do. The cartridges (cartridge A, cartridge portion A) described in Patent Documents 1 and 2 are no exception, and although not particularly described, each member is a combination of a metal member and a synthetic resin member. .. However, the container in which the metal member and the synthetic resin member are combined has no choice but to be discarded after being used up, and it is not possible to carry out further recycling (Recycle).

In order to recycle the cartridge, it is possible to mold all the parts from a material with excellent recyclability (a recycling system has been established). Especially when molding a cartridge for a stick-shaped cosmetic container from a metal material with excellent recyclability, the thin plate is plastically processed such as press processing, post-processing such as cutting processing, decoration, rust prevention treatment, etc. due to mass productivity. It was molded into a member through a processing process. Due to this processing, burrs may be generated on the end face of the metal material, or the end face may be sharpened. A deburring process was performed so as not to damage the user by the burrs and sharp end faces, and the structure was such that the end faces were not directed outward like the sleeves (sleeve 11, outer cylinder 1) of Patent Document 1 and Patent Document 2. Further, even a minute burr on the end face causes a rough and unpleasant rubbing, so that the rubbing between different materials such as synthetic resin and metal has been eliminated. However, when each member is molded from a single metal material with the highest priority on recyclability, unpleasant rubbing has a great influence on the operability during the feeding rotation operation.

In view of the above points, the present invention solves the problem of operability when the cartridge cannot be used alone, and all the constituent members of the cartridge are molded from an aluminum material, which is said to be an excellent student of recycling, and molded from a single metal material. We will provide an environment-friendly stick-shaped cosmetics delivery container that can be recycled and disposed of.

A holding cylinder 2 that holds the stick-shaped cosmetics 1 and has a screw protrusion 22 protruding from the side wall and the holding cylinder 2 are slidably installed, and the screw protrusion 22 of the holding cylinder 2 penetrates the side wall. A guide elongated hole 34 that makes the holding cylinder 2 non-rotatable is bored long in the axial direction, and a body cylinder 3 having an engaging hole 311 formed in the bottom surface 31 and the body cylinder 3 are rotatably installed. , The sleeve 104 is provided with a spiral groove 142 into which the screwing protrusion 22 penetrating the body cylinder 3 is screwed on the inner side wall, and the holding cylinder 2 is slid up and down by the relative rotation of the sleeve 104 and the body cylinder 3. The cartridge A1 is detachably attached to a holder B provided with a connecting member 8 that engages with the engaging hole 311 of the body cylinder 3 to transmit rotation to the body cylinder 3. In the charge feeding container, the holding cylinder 2, the body cylinder 3 and the sleeve 104 constituting the cartridge A1 are formed of a single material, and the sleeve 104 has a bar-shaped cosmetic 1 outlet 41 at the upper end and a bent portion at the lower end. 45 is provided, and the body cylinder 3 is held between the opening edge portion 411 and the bent portion 45 of the entrance / exit 41 so as not to fall off.

Further, a holding cylinder 2 that holds the stick-shaped cosmetics 1 and has a screw protrusion 22 protruding from the side wall, and the holding cylinder 2 are slidably installed, and the screw protrusion 22 of the holding cylinder 2 is provided on the side wall. A guide elongated hole 34 that penetrates and makes the holding cylinder 2 non-rotatable is bored long in the axial direction, and an engaging hole 311 is bored in the bottom surface 31. A spiral cylinder 9 provided with a spiral groove 242 to be held and screwed with a screwing protrusion 22 penetrating the body cylinder 3 on the inner side wall, and the spiral cylinder 9 are fastened to the inner wall to interior the body cylinder 3. A cartridge A2 composed of a sleeve 204 and having a feeding mechanism for sliding the holding cylinder 2 up and down by the relative rotation of the sleeve 204 and the body cylinder 3 is engaged with the engaging hole 311 of the body cylinder 3 to be engaged with the body cylinder 3. In a cartridge-type rod-shaped cosmetics feeding container that is detachably attached to a holder B provided with a connecting member 8 for transmitting rotation, a holding cylinder 2, a body cylinder 3, a spiral cylinder 9 and a cartridge cylinder 9 constituting the cartridge A2 are provided. The sleeve 204 is formed of a single material, and the sleeve 204 is provided with a protrusion 41 for the stick-shaped cosmetics 1 at the upper end and a bent portion 45 at the lower end, and the sleeve 204 is provided between the opening edge portion 411 and the bent portion 45 of the protrusion 41. Hold the cylinder 3 so that it cannot be dropped off.

The constituent members constituting the cartridges A1 and A2 may be made of a single material of aluminum.

Further, a reinforcing bead 331 whose tip is curled inward may be formed on the upper end of the body cylinder 3 and brought into contact with the opening edges 411 of the sleeves 104 and 204 that rotate relative to each other.

As described above, the present invention rotatably rotates one of the body cylinders 3 and the sleeves 104 and 204 of the members constituting the feeding mechanism for feeding the stick-shaped cosmetics 1 into the sleeves 104 and 204. It is stored, and the externally exposed portion of the body cylinder 3 is only near the engaging hole 311 on the bottom surface 31. As a result, the body cylinder 3 and the sleeves 104 and 204 cannot be rotated relative to each other with the cartridges A1 and A2 alone, the stick-shaped cosmetics 1 cannot be delivered, and the cartridges A1 and A2 cannot be used alone. However, when the cartridges A1 and A2 are mounted on the holder B, the connecting member 8 of the holder B engages with the engaging hole 311 of the body cylinder 3 and can transmit the rotation to the body cylinder 3. As a result, the sleeves 104 and 204 and the body cylinder 3 are relatively rotated to pay out the stick-shaped cosmetics 1, and the cartridges A1 and A2 can be used.

Further, the shape of each member of the cartridges A1 and A2 of the present invention is a shape that can be formed by processing a thin metal plate. In other words, even a single aluminum material, which is said to be an excellent student of recycling, can be molded. In this case, the cartridges A1 and A2 can be disposed of and recycled as aluminum waste, and an environment-friendly stick-shaped cosmetics feeding container can be provided.

Further, the cartridges A1 and A2 have the body cylinder 3 and the sleeve 104 that rotate relative to each other by forming a reinforcing bead 331 in which the upper end of the body cylinder 3 is curled inward and the upper end of the body cylinder 3 is directed inward. The contact portion of 204 has an upper end between the reinforcing bead 331 and the opening edge portion 411, and a lower end between the bottom surface 31 of the body cylinder 3 and the upper surface of the bent portion 45, and there is no rubbing of the end faces, which makes the operation feeling unpleasant. Factors can be eliminated.

Further, since the bent portion 45 is formed by machining after assembling the body cylinder 3, it is assumed that the body cylinder 3 in the sleeves 104 and 204 is pulled in the falling direction due to the insertion and removal of the cartridges A1 and A2. However, the body cylinder 3 will not fall off unless the sleeves 104 and 204 are destroyed.

Further, the members exposed to the outside of the cartridges A1 and A2 are only the sleeves 104 and 204, the upper end of which is the appearance opening 41 and the lower end of which is the bent portion 45. Since the end faces of both the indentation port 41 and the bent portion 45 face inward (center direction), the end faces are not exposed to the outside and there is no concern of damaging the user.

The cartridge-type rod-shaped cosmetics feeding container according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 7. The cartridge-type stick-shaped cosmetics feeding container according to the embodiment of the present invention is formed by detachably attaching the cartridge A1 to the holder B as shown in FIGS. 1 and 2.

First, the cartridge A1 will be described with reference to FIGS. 1, 3 to 7. The cartridge A1 is composed of a holding cylinder 2, a body cylinder 3, and a sleeve 104 (see FIG. 5). Each of these members is molded from a single material, such as aluminum, which is suitable for recycling.

The holding cylinder 2 has a cup shape and fits and holds the lower end portion of the stick-shaped cosmetics 1. On the inner peripheral wall of the holding cylinder 2, a plurality of holding ribs 21 that bite into the stick-shaped cosmetic 1 and hold the stick-shaped cosmetic 1 are projected evenly at equal intervals in parallel with the axis. Further, a screwing protrusion 22 is provided on the side wall of the holding cylinder 2. A pair of screwing protrusions 22 are provided on the side wall of the holding cylinder 2 at intervals of 180 degrees. The holding cylinder 2 is vertically slidable inside the body cylinder 3.

The body cylinder 3 has an elongated pipe shape having a bottom surface 31. The bottom end portion of the bottom surface 31 of the body cylinder 3 is a base portion 32 having a slightly larger outer diameter. Further, an engaging hole 311 having a regular octagonal shape is bored in the bottom surface 31. Above the base 32 of the body cylinder 3, there is an accommodating portion 33 that accommodates the holding cylinder 2 so as to be slidable up and down.

A guide elongated hole 34 through which the screwed protrusion 22 of the holding cylinder 2 penetrates is formed in the side wall of the accommodating portion 33 in an elongated shape parallel to the axis. The guide elongated holes 34 are cut out to reach the upper end of the body cylinder 3 at the same number and intervals as the screwing protrusions 22 of the holding cylinder 2. As a result, the holding cylinder 2 can be assembled from above by aligning the screwing protrusion 22 with the guide elongated hole 34. Further, the holding cylinder 2 slides in the accommodating portion 33 in a non-rotatable state by the guide elongated hole 34. Further, in the guide elongated hole 34, an upper pocket 342 bent in the left direction orthogonal to the axis line is continuous with the left side wall 341 near the upper end, and is continuous with the right side wall 343 at the lower end of the guide elongated hole 34. Each of the lower pockets 344 bent to the right orthogonal to the axis is provided.

Further, a reinforcing bead 331 is provided on the upper end outer wall of the accommodating portion 33 in a direction orthogonal to the axis along the peripheral edge portion. The reinforcing bead 331 projects from the inside toward the outside, and is formed so as to have a slightly larger diameter in the outer diameter direction of the accommodating portion 33. Due to the molding of the reinforcing bead 331, the tip of the accommodating portion 33 is bent inward. The reinforcing bead 331 improves the strength of the upper end of the accommodating portion 33, and even though it is cut out by the guide elongated hole 34, it is less likely to be deformed. The body cylinder 3 is rotatably built in the sleeve 104.

The sleeve 104 has a pipe shape, and a spawning port 41 in which the stick-shaped cosmetics 1 appear is formed at the upper end thereof. The haunting port 41 has a diameter smaller than the inner diameter of the sleeve 104 and has an opening edge portion 411. The upper end of the accommodating portion 33 (the tip of the reinforcing bead 331) of the body cylinder 3 is in contact with the opening edge portion 411. Further, when the sleeve 104 is used alone or when the body cylinder 3 is assembled, the lower end of the sleeve 104 extends downward from the body cylinder 3 (see FIG. 6).

A knurled spiral groove 142 (left-handed screw in the embodiment of the present invention) is screwed into a facing portion between the upper pocket 342 and the lower pocket 344 of the accommodating portion 33 of the body cylinder 3 on the inner surface of the sleeve 104. There is. The knurled spiral groove 142 has innumerable fine spiral stripes and is screwed like a knurl on the entire inner circumference. The mountain diameter (inner diameter) of the knurled spiral groove 142 is slightly larger than the outer diameter of the accommodating portion 33 of the body cylinder 3. The knurled spiral groove 142 is screwed with the screwed protrusion 22 of the holding cylinder 2 that penetrates the guide elongated hole 34 of the body cylinder 3. The screw surface 221 of the screw protrusion 22 is provided with fine irregularities in which a plurality of adjacent spiral grooves 142 are screwed together.

The portion above the spiral groove 142 on the inner surface of the sleeve 104 and facing the reinforcing bead 331 of the accommodating portion 33 of the body cylinder 3 is the sliding contact portion 43. The inner diameter of the sliding contact portion 43 is the same as the mountain diameter of the knurled spiral groove 42, and is the same as or slightly larger than the outer diameter of the reinforcing bead 331, and the reinforcing bead 331 of the body cylinder 3 is a sleeve. The rotational resistance is reduced by making line contact with the sliding contact portion 43 on the inner surface of 4.

Further, the portion below the spiral groove 142 on the inner surface of the sleeve 104 and facing the base portion 32 of the body cylinder 3 is a large diameter portion 44. The large diameter portion 44 has a larger diameter than the sliding contact portion 43, is substantially the same diameter as the valley diameter of the knurled spiral groove 142, and is slightly larger than the outer diameter of the base portion 32. As a result, the body cylinder 3 is rotatable in the sleeve 4.

Further, at the lower end of the sleeve 4, after assembling the body cylinder 3, a portion protruding from the body cylinder 3 is bent inward along the base portion 32 of the body cylinder 3 to provide a bent portion 45. As a result, the upper end of the body cylinder 3 and the upper end of the reinforcing bead 331 abut on the opening edge portion 411 of the entrance 41, and the bottom surface 31 of the lower end of the body cylinder 3 abuts on the bent portion 45, whereby the body cylinder 3 comes into contact with the sleeve 104. It is rotatably held inside so that it cannot fall off. The bottom surface 31 of the body cylinder 3 is exposed on the lower surface of the sleeve 104 so that the engaging hole 311 can be seen.

The cartridge A1 of the first embodiment of the present invention has the above configuration. In the cartridge A1 of the first embodiment of the present invention, all the constituent members are molded from a single metal material such as aluminum, but the molding method is generally mass-produced or plastic working such as press molding. As shown in FIG. 5, the shapes of the constituent members, the holding cylinder 2, the body cylinder 3, and the sleeve 104 of the cartridge A1 of the first embodiment of the present invention do not have a particularly special shape and are generally known. Since it can be molded by the plastic working process, the description of the molding method in this place will be omitted.

Next, the method of assembling the cartridge A1 according to the first embodiment of the present invention will be described with reference to FIGS. 6 and 7. The holding cylinder 2 is mounted from the upper end of the body cylinder 3 by aligning the screwing protrusion 22 with the guide elongated hole 34 cut out to the upper end. Initially, the sleeve 104 does not have the bent portion 45 at the rear end formed as shown in FIGS. 6 and 7. Therefore, the body cylinder 3 and the holding cylinder 2 attached to the body cylinder 3 can be assembled from the rear end of the sleeve 104. After assembling the body cylinder 3, as shown in FIG. 4, the bent portion 45 is formed by bending the rear end of the sleeve 104 toward the center, and the body cylinder 3 is attached to the opening edge of the opening / exit 41 of the sleeve 104. It is rotatably held between the portion 411 and the bent portion 45 so as not to fall off.

Next, the holder B to which the cartridge A1 is mounted will be described with reference to FIG. The holder B is composed of a cap 5, a middle cylinder 6, an outer cylinder 7, and a connecting member 8, and the middle cylinder 6, the outer cylinder 7, and the connecting member 8 are assembled so as not to be detachable. Since the holder B is used repeatedly, there are no restrictions on the material of each member.

The outer cylinder 7 has a bottomed cylinder shape, and the connecting member 8 is fastened to the inner bottom portion of the outer cylinder 7.

The middle cylinder 6 has a pipe shape with both ends open, and is inserted and fastened from the upper end of the outer cylinder 7. The lower end of the middle cylinder 6 is in contact with the collar-shaped base 81 of the connecting member 8 and holds the connecting member 8. The upper end portion of the inner cylinder 6 is a fitting portion 61 that protrudes upward from the outer cylinder 7 and fits the cap 5 so as to be removable. Then, the cartridge A1 is inserted through the middle cylinder 6.

The connecting member 8 has a connecting piece 82 projecting from the central portion of the collar-shaped base 81. The connecting piece 82 is adapted to enter the engaging hole 311 of the cartridge A1 when the cartridge A1 is mounted. The horizontal cross section of the connecting piece 82 has a similar shape slightly smaller than the engaging hole 311 of the body cylinder 3, and is irrotatably engaged with the engaging hole 311. As a result, the rotation of the holder B can be transmitted to the body cylinder 3 of the cartridge A1 via the connecting piece 82. Further, the upper end of the connecting piece 82 protrudes into the engaging hole 311, and the engaging protrusion 821 protrudes from the outer wall of the connecting piece 82, and is detachably engaged with the edge of the engaging hole 311. ing. As a result, the cartridge A and the holder B are connected so as to be arbitrarily removable.

The cartridge-type stick-shaped cosmetics feeding container according to the first embodiment of the present invention has the above configuration. Therefore, in the cartridge A1 alone, one of the relative rotating members, the body cylinder 3 and the sleeve 104, of the feeding mechanism for feeding the stick-shaped cosmetics 1, is built in the sleeve 104. The relative rotation operation between 3 and the sleeve 104 cannot be performed, and the cartridge A1 alone cannot be extended, that is, the cartridge A1 alone cannot be used (see FIG. 1).

Here, when the cartridge A1 is attached to the holder B, the connecting piece 82 of the connecting member 8 of the holder B is non-rotatably engaged with the engaging hole 311 of the body cylinder 3 of the cartridge A1. As a result, the rotation of the holder B is transmitted to the body cylinder 3, the holder B and the body cylinder 3 of the cartridge A1 rotate integrally, and the cartridge A1 can be extended (used). Due to the relative rotation of the body cylinder 3 and the sleeve 104, the screwing protrusion 22 of the holding cylinder 2 whose rotation is blocked by the guide slot 34 of the body cylinder 3 is screwed into the spiral groove 142 of the sleeve 104 that rotates relative to each other. Therefore, the holding cylinder 2 slides up and down due to the screwing action, and the stick-shaped cosmetics 1 held by the holding cylinder 2 appear and disappear from the appearance opening 41 of the sleeve 104 (see FIG. 2).

More specifically, when the sleeve 104 is rotated counterclockwise while holding the holder B, the screwed protrusion 22 screwed into the spiral groove 142 of the sleeve 104 is the guide length of the body cylinder 3. Since it comes into contact with the left side wall 341 of the hole 34 and is prevented from being driven by the sleeve 104, the holding cylinder 2 rises along the spiral groove 142. At this time, the screwed protrusion 22 moves while abutting on the left side wall 341 of the guide elongated hole 34. Here, since the upper pocket 342 is connected to the left side wall 341 of the guide slot 34, the screwed protrusion 22 plunges into the upper pocket 342. The screwed protrusion 22 in the upper pocket 342 cannot be raised, and the holding cylinder 2 (stick-shaped cosmetics 1) can be raised only.

When the holder B is held and the sleeve 104 is rotated in the reverse direction (clockwise rotation / clockwise rotation) in this state, the holding cylinder 2 in which the screwing protrusion 22 is screwed into the spiral groove 142 of the sleeve 104 is also driven. Due to the driven movement of the holding cylinder 2, the screwing protrusion 22 comes off the upper pocket 342 of the body cylinder 3 and comes into contact with the right side wall 343 of the guide slot 34 to prevent the sleeve 104 from being driven. The holding cylinder 2 descends along the spiral groove 142. At this time, the screwed protrusion 22 moves while abutting on the right side wall 343 of the guide elongated hole 34. Here, since the lower pocket 344 is connected to the right side wall 343 of the guide slot 34, the screwed protrusion 22 plunges into the lower pocket 344. The screwed protrusion 22 in the lower pocket 344 cannot be lowered, and the holding cylinder 2 (stick-shaped cosmetics 1) is limited to lowering.

As described above, the holding cylinder 2 reciprocates between the ascending limit and the descending limit, and the screwed protrusion 22 does not derail from the spiral groove 142. Further, when the screwed protrusion 22 engages with the upper pocket 342, even if stress is applied to the holding cylinder 2 in the downward direction such as when the stick-shaped cosmetic 1 is applied, the horizontal portion of the upper pocket 342 causes a careless descent. Is blocked. Similarly, when the screwed protrusion 22 engages with the lower pocket 344, the lower pocket 344 inadvertently raises the holding cylinder 2 even if stress is applied in the ascending direction of the holding cylinder 2 such as an impact during carrying. Be blocked.

Next, Example 2 of the present invention will be described with reference to FIG. The basic configuration is the same as that of the first embodiment, and the difference is in the cartridge A2 that is recycled and discarded. Hereinafter, the cartridge A2 of the second embodiment of the present invention will be described.

The cartridge A2 of the second embodiment of the present invention is composed of a holding cylinder 2, a body cylinder 3, a sleeve 204, and a spiral cylinder 9. Each of these members is molded from a single material, such as aluminum, which is suitable for recycling. The holding cylinder 2 has the same configuration as that of the first embodiment, and is internally slidably slidably installed in the body cylinder 3. The body cylinder 3 has the same configuration as that of the first embodiment, and the spiral cylinder 8 is rotatably held on the outer periphery of the accommodating portion 33 provided with the guide elongated hole 34.

The spiral cylinder 8 has a pipe shape, and a spiral groove 242 is screwed on the inner surface facing between the upper pocket 342 and the lower pocket 344 of the accommodating portion 33 of the body cylinder 3. The spiral groove 242 has a number of threads that is an integral multiple of the number of screwed protrusions 22 of the holding cylinder 2. The screw protrusion 22 of the holding cylinder 2 penetrating the guide slot 34 of the body cylinder 3 is screwed into the spiral groove 242, and one screw protrusion 22 is one spiral groove 242. Is screwed into. The spiral cylinder 8 is fastened to the inner wall of the sleeve 204.

The sleeve 204 has a pipe shape, and the inner diameter is slightly larger than the outer diameter of the base 32 of the body cylinder 3. At the upper end of the sleeve 204, a haunting port 41 in which the stick-shaped cosmetics 1 appear is bored. The haunting port 41 has a diameter smaller than the inner diameter of the sleeve 204 and has an opening edge portion 411. The tip of the body cylinder 3 (the tip of the reinforcing bead 331) is in contact with the opening edge portion 411.

Further, when the sleeve 204 is a single body, the lower end is straight as in the first embodiment, and the body cylinder 3 to which the holding cylinder 2 is assembled can be inserted from below. Then, after assembling the body cylinder 3, the lower end of the sleeve 204 (the portion protruding downward from the body cylinder 3) is bent along the base portion 32 of the body cylinder 3 to form the bent portion 45. As a result, the upper end (reinforcing bead 331) of the body cylinder 3 abuts on the opening edge portion 411 of the entrance 41 of the sleeve 204, and the bottom surface 31 at the lower end of the body cylinder 3 abuts on the bent portion 45, whereby the body cylinder 3 becomes a sleeve. It is rotatably held in 204 so as not to fall off. The bottom surface 31 of the body cylinder 3 is exposed on the lower surface of the sleeve 204 so that the engaging hole 311 can be seen.

The above is the configuration of the cartridge A2 of the second embodiment of the present invention. The molding method and the assembling method of each component are the same as the cartridge A1 of the first embodiment of the present invention. In the second embodiment, the spiral cylinder 8 is increased by one part as compared with the first embodiment, but the spiral cylinder 8 can be a member specialized for the spiral groove 242, so that the spiral cylinder 8 is not restricted as compared with the first embodiment. The groove 242 can be formed. Further, since it is fixed in the sleeve 4, the appearance can be molded without any restriction.

In the embodiment, the engaging hole 311 of the body cylinder 3 of the cartridges A1 and A2 has a regular octagonal shape, and the connecting piece 82 of the connecting member 8 of the holder B has a similar figure 8 corresponding to the engaging hole 311.
