Description

Technical Field

[0001] The present invention relates to a rod-shaped cosmetic dispensing container for storing rod-shaped cosmetics such as lipsticks and stick foundations, and more particularly to a rod-shaped cosmetic dispensing container that takes environmental considerations into account and aims to reduce the environmental impact.

Background Art

[0002] Conventionally, rod-shaped cosmetic containers containing rod-shaped cosmetics such as lipsticks and stick foundations have used materials appropriately in their respective places. For example, metal members with excellent strength and decorativeness are used for the members exposed to the outside, synthetic resins with excellent moldability and chemical resistance such as PP (polypropylene) are used for the members holding the rod-shaped cosmetics, and synthetic resins with excellent moldability and slidability such as POM (polyacetal) are used for the mechanical parts such as the dispensing mechanism parts.

[0003] However, considering the environmental impact during disposal and the like, since a plurality of types of materials such as metal and synthetic resin are combined, the current situation is not preferable. Therefore, a rod-shaped cosmetic dispensing container in which all of the constituent members are formed of metal, like the lipstick case of Patent Document 1, is known. In this configuration, all members can be formed of the same metal without impairing the decorativeness of the exterior portion. That is, it can be easily recycled without separate disposal, and the environmental impact can be reduced.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In the case of the structure of the lipstick case of Patent Document 1, the red cylinder (red plate 10) that holds the stick-shaped cosmetic is cup-shaped and can be easily formed by general pressing. However, like the red cylinder (receptacle 12) of the extraction container shown in Patent Document 2, a shape with a bottom in the middle of the pipe is difficult to form in one part without special impact molding like Figure 2 of the stick-shaped cosmetic extrusion container of Patent Document 3. This kind of special impact molding has limited working places where it can be processed and the mold cost is also high, so it is not practical. As a result, compared with the red cylinder of the lipstick case of Patent Document 1, the cost has increased significantly.

[0009] In addition, the outer diameter WA1 of the holding cylinder 21 of the red cylinder 2 and the outer diameter WB1 of the leg-shaped part 221 of the leg cylinder 22 are the same. The inner diameter WA2 of the fastening part 212 of the holding cylinder 2 is the same as or slightly smaller than the outer diameter WB2 of the connecting part 223 of the leg cylinder 22, and a stepped part 225 is formed between the connecting part 223 and the leg-shaped part 221 of the leg cylinder 22. The holding cylinder 21 and the leg cylinder 22 are fastened with the end face 214 of the fastening part 212 of the holding cylinder 21 in contact with the stepped part 225, forming the red cylinder 2.

[0010] The red cylinder 2 of the present invention is manufactured through a forming process, a surface treatment process, a cutting process, and an assembly process. The red cylinder fabric 20 is the of the leg cylinder 22 the at the lower end of the leg-shaped part 221 , the of the holding cylinder 21 the the fastening part 212 lower end of to , the holding cylinder 21 is joined in an upside-down state, and the holding cylinder 21 and the leg cylinder 22 are a cap shape integrally connected are doing.

Advantages of the Invention

[0012] As described above, in the present invention, all the constituent members of the feeding mechanism portion 11 and the exterior body 12 are a rod-shaped cosmetic feeding container made of the same metal material. Here, when the feeding mechanism portion 11 is operated through the exterior body 12 to relatively rotate the storage cylinder body 3 and the spool cylinder 4, the screwing protrusion 224 of the leg-shaped part 221 of the red cylinder 2 penetrates the guide slit 31 of the storage cylinder body 3 and is in a state where rotation is blocked, and is screwed into the spiral groove 42 of the relatively rotating spool cylinder 4. Therefore, due to the screwing action, the red cylinder 2 and the rod-shaped cosmetic 1 slide up and down. That is, the appearance and disappearance operation of the rod-shaped cosmetic can be performed by the same operation as that of the conventional rod-shaped cosmetic feeding container.

[0013] Moreover, by assembling a pipe-shaped metal holding cylinder 21 having holding ribs 213 on the inner surface to the upper part of a cap-shaped metal leg cylinder 22 having a ceiling portion 222 and protruding screwing protrusions 224 on the lower side wall, a metal red cylinder 2 having a bottom in the middle of the pipe can be easily obtained. Since the holding cylinder 21 and the leg cylinder 22 of this red cylinder 2 have shapes that can be formed by pressing, the mold cost and the manufacturing cost can be kept low. In addition, by replacing the processes during the processing steps, it is possible to easily cope with the holding ribs 213 and the shape of the bottom according to the filling and mounting method of the rod-shaped cosmetic 1.

[0014] Furthermore, since the red cylinder 2 is divided into a holding cylinder 21 having a holding portion 211 for holding the rod-shaped cosmetic 1 and a leg cylinder 22 provided with a screwing projection 224 that screws into the spiral groove 42, the wall thickness required for each can be set separately. That is, the holding cylinder 21 is made thin in order to hold the rod-shaped cosmetic 1 and to improve the cooling property during solidification of the cosmetic. Also, the leg cylinder 22 needs to have a certain degree of strength so that the screwing projection 224 does not come off from the spiral groove 42, and thus it is made thick.

[0015] Also, in the method for manufacturing the red cylinder 2 of the present invention, after molding and surface treatment of a red cylinder blank 20 in which a pipe-shaped holding cylinder 21 having a holding rib 213 on the inner surface and a cap-shaped leg cylinder 22 having a ceiling portion 222 and a screwing projection 224 protruding from the side wall are integrated, it is cut and divided into the holding cylinder 21 and the leg cylinder 22. Therefore, the molding die, the molding process, and the surface treatment process are sufficient for one part. The shape of this red cylinder blank 20 is a shape that can be press-worked, and a cutting process and an assembly process are required. However, compared with the red cylinder of the lipstick case in Patent Document 1, a metal red cylinder having a shape with a bottom in the middle of the pipe can be obtained with a minimal cost increase.

[0017] As Embodiment 1 of the present invention, an embodiment of a push-in type metal rod-shaped cosmetic dispensing container in which a pre-formed rod-shaped cosmetic 1 is set in a container will be described with reference to FIGS. 1, 2, and 7. The metal rod-shaped cosmetic dispensing container of the present invention includes a feeding mechanism portion 11 for sliding the rod-shaped cosmetic 1 up and down, and an exterior body 12 that internally houses the feeding mechanism portion 11 so that it can be operated from the outside. All the constituent members of the feeding mechanism portion 11 and the exterior body 12 are formed from an aluminum material by pressing or the like. This feeding mechanism portion 11 is composed of a red cylinder 2, a storage cylinder body 3, and a spiral cylinder 4, and the exterior body 12 is composed of a middle cylinder 5, a hakama cylinder 6, and a cap 7.

[0018] As shown in FIG. 7, the red cylinder 2 of this feeding mechanism portion 11 includes a holding cylinder 21 and, at the lower end of this holding cylinder 21 The leg cylinder 22 is fixed and integrated.

[0019] The holding cylinder 21 has a pipe shape with both ends open, which is composed of a holding portion 211 and a fastening portion 212 continuous with this holding portion 211. A plurality of holding ribs 213 that are long in the axial direction are evenly projected on the inner peripheral wall of this holding portion 211, biting into and holding the rod-shaped cosmetic 1. These holding ribs 213 are projected from the outer wall side of the holding portion 211 toward the inner side.

[0020] The leg cylinder 22 is composed of a leg-shaped portion 221 and a connecting portion 223 having a ceiling portion 222 continuous with the leg-shaped portion 221, and has a cap shape with one end open. The outer diameter WB1 of the leg-shaped portion 221 is the same as the outer diameter WA1 of the holding cylinder 21, and the outer diameter WB2 of the connecting portion 223 is the same as or slightly smaller than the inner diameter WA2 of the fastening portion 212 of the holding cylinder 21, forming a stepped portion 225 at the joint portion between the leg-shaped portion 221 and the connecting portion 223. On the outer side wall of the lower part of the leg-shaped portion 221, a screwing protrusion 224 is protruding. This screwing protrusion 224 protrudes from the inner wall side toward the outside at two opposed positions on the outer periphery of the leg-shaped portion 221.

[0021] Then, the fastening portion 212 of the holding cylinder 21 is fitted into the connecting portion 223 of the leg cylinder 22 and fastened in a state where the end face 214 of the fastening portion 212 abuts against the stepped portion 225, and the ceiling portion 222 of the connecting portion 223 forms the bottom surface of the holding portion 211. A small through hole 226 is formed in this ceiling portion 222 for air venting when a set of stick cosmetics 1 is formed.

[0022] The stick cosmetics 1 and the red cylinder 2 are internally installed in the storage cylinder body 3 so as to be slidable up and down. From the lower end of this storage cylinder body 3, a guide slit 31 is formed longitudinally in the axial direction. This guide slit 31 is provided in the number and positions corresponding to the screwing protrusions 224 of the red cylinder 2. The screwing protrusions 224 of the red cylinder 2 are inserted and engaged from the lower end, and the red cylinder 2 is guided to be slidable up and down while being restricted from rotating. An engaging rib 32 protrudes from the inner wall side toward the outside and is provided around the outer periphery above this guide slit 31. Incidentally, this engaging rib 32 is positioned below the upper end of the red cylinder 2 when the stored red cylinder 2 is at the lower limit, and does not affect the stick cosmetics 1 held by the red cylinder 2.

[0023] The lower part of this storage cylinder body 3 is rotatably inserted from above the upper end of the spiral cylinder 4. This spiral cylinder 4 has a thin-walled cup shape with a bottom 41, the upper end abuts against the lower surface of the engaging rib 32 of the storage cylinder body 3, and the lower end abuts against the bottom 41 of the storage cylinder body 3. On the inner wall of this spiral cylinder 4, a spiral groove 42 is provided for screwing the screwing protrusion 224 of the red cylinder 2 that penetrates the guide slit 31 of the storage cylinder body 3. This spiral groove 42 is grooved at the upper end of the spiral cylinder 4, and the screwing protrusion 224 can be screwed in from the upper end. Also, as shown in FIGS. 1 and 2, this spiral groove 42 is formed from the inner wall side of the spiral cylinder 4 toward the outside, and the outer wall of the spiral cylinder 4 protrudes in the shape of the spiral groove 42.

[0024] The description of the feeding mechanism part 11 is as above. Here, when holding the storage cylinder body 3 and rotating the spiral cylinder 4, the storage cylinder body 3 and the spiral cylinder 4 rotate relative to each other. Since the red cylinder 2 in the storage cylinder body 3 is screwed into the spiral groove 42 of the rotating spiral cylinder 4 in a state where the screwing protrusion 224 penetrates the guide slit 31 of the storage cylinder body 3 and does not rotate, the red cylinder 2 slides up and down in the storage cylinder body 3 due to the screwing action, and the rod-shaped cosmetic 1 appears and disappears from the tip of the storage cylinder body 3. And, as shown in FIG. 1, the lower end of the red cylinder 2 abuts against the bottom 41 of the spiral cylinder 4 to become the lower limit of the descent of the red cylinder 2, and as shown in FIG. 2, the screwing protrusion 224 abuts against the upper end of the guide slit 31 to become the upper limit of the ascent of the red cylinder 2.

[0025] Next, the exterior body 12 that houses the feeding mechanism section 11 will be described. The middle cylinder 5 is in the shape of a pipe with both ends open, and the bobbin cylinder 4 of the feeding mechanism section 11 is inserted and fixed from below. The upper end of this middle cylinder 5 is a tip portion 53 with an inner diameter smaller than the outer diameter of the engaging rib 32 of the storage cylinder body 3 and slightly larger than the outer diameter of the storage cylinder body 3, becoming narrower. Between the inside of this tip portion 53 and the tip of the bobbin cylinder 4, there is a clamping portion 51 that rotatably and non - detachablely clamps the engaging rib 32 of the storage cylinder body 3. The lower part of this middle cylinder 5 is inserted and fixed into the hakama cylinder 6 in the shape of a bottomed cylinder, and the upper end is a fitting portion 52 that protrudes from the upper end of the hakama cylinder 6 and into which the cap 7 is detachably fitted. As a result, when the cap 7 is removed, the storage cylinder body 3 is held, and the hakama cylinder 6 is rotated, the bobbin cylinder 4 fixed to the hakama cylinder 6 via the middle cylinder 5 rotates, and relative rotation between the storage cylinder body 3 and the bobbin cylinder 4 is established.

[0026] The above is the configuration of the elongated cosmetic feeding container of the present invention. Next, the manufacturing method of the red cylinder of the present invention will be described with reference to FIGS. 3 to 7. FIG. 3 is a flowchart summarizing the manufacturing process of the red cylinder of the present invention. The manufacturing process of the red cylinder includes a forming process of press - forming a predetermined shape of the red cylinder blank 20 from an aluminum plate (metal thin plate), a surface treatment process of subjecting the press - formed red cylinder blank 20 to an anodic oxidation film treatment, a cutting process of cutting the surface - treated red cylinder blank 20 into two parts, namely the holding cylinder 21 and the leg cylinder 22 two members of and an assembling process of assembling and fixing these two - divided holding cylinder 21 and leg cylinder 22 to form the red cylinder 2. one member of

[0027] In the forming process, the aluminum thin plate is press - formed into the shape of the red cylinder blank 20 as shown in FIG. 4. This red cylinder blank 20 has a shape that connects at the lower end, the holding portion 212 of the holding cylinder 21 the lower end, the holding cylinder 21 is joined in an upside-down state, and the holding cylinder 21 and the leg cylinder 22 are integrated and cap the leg - shaped portion 221 of the leg cylinder 22 is. The total length L1 of this red cylinder fabric 20 is the sum of the length LA of the holding cylinder 21 and the length LB of the leg cylinder 22. Also, the outer diameter WB1 of the leg portion 221 of the leg cylinder 22 and the outer diameter WA1 of the holding cylinder 21 are the same. However, the wall thickness TA of the holding cylinder 21 is thinner than the wall thickness TB of the leg portion 221 of the leg cylinder 22, creating a step on the inner wall. The outer diameter WB2 of the connecting portion 223 of the leg cylinder 22 is the same as or slightly smaller than the inner diameter WA2 of the fixing portion 212 of the holding cylinder 21, and a stepped portion 225 with a thickness of TA + alpha of the holding cylinder 21 is formed between the outer wall of the connecting portion 223 of the leg cylinder 22 and the outer wall of the leg portion 221.

[0028] In the surface treatment process, an anodic oxidation film treatment is performed on the red cylinder fabric 20 formed in the forming process shown in FIG. 4.

[0029] In the cutting process, it is cut along the cutting line CL directly below the step on the lower inner wall of the red cylinder fabric 20 shown in FIG. 4, and the red cylinder fabric 20 is divided into the holding cylinder 21 and the leg cylinder 22. two members of This is shown in FIG. 5 after cutting. The cutting part of the holding cylinder 21 becomes the end face 214 of the fixing part 212, and the cutting part of the leg cylinder 22 becomes the lower end of the leg portion 221. The leg cylinder 22 is upside-down.

[0030] In the assembly process, as shown in FIG. 5, the holding cylinder 21 obtained from the red cylinder fabric 20 in the cutting process Two-part is , one of fitted and fixed to the connecting portion 223 of the leg cylinder 22 with the end face 214 (cutting surface) of the fixing part 212 facing down, as shown in FIG. 6. rotate At this time, the end face 214 of the holding cylinder 21 abuts against the stepped portion 225 of the leg cylinder 22. The total length L2 of the red cylinder 2 is the sum of the length LA of the holding cylinder 21 and the length LB1 of the leg portion 221 of the leg cylinder 22, and the depth D of the holding portion of the rod-shaped cosmetic 1 is the difference between the length LA of the holding cylinder 21 and the length LB2 of the connecting portion 223 of the leg cylinder 22. from above fitted , integrally fixed do to form the red cylinder 2 shown in Figure 7. At this time, the end face 214 of the holding cylinder 21 abuts against the stepped portion 225 of the leg cylinder 22. The total length L2 of the red cylinder 2 is the sum of the length LA of the holding cylinder 21 and the length LB1 of the leg portion 221 of the leg cylinder 22, and the depth D of the holding portion of the rod-shaped cosmetic 1 is the difference between the length LA of the holding cylinder 21 and the length LB2 of the connecting portion 223 of the leg cylinder 22.

Example 2

[0031] As Example 2, an example of an upward filling type metal rod-shaped cosmetic dispensing container in which the melted cosmetic is poured from above the container and cooled and solidified will be described with reference to FIG. 8. The structure and process of the insertion type metal rod-shaped cosmetic dispensing container of Example 1 described above are the same, but the details of the red cylinder 2 are different. The differences will be described below. The holding ribs 213 evenly provided on the inner peripheral wall of the holding portion 211 of the red cylinder 2 are in an inverted T shape formed by combining circumferential ribs and axial ribs. Nothing is provided on the ceiling portion 222 of the leg cylinder 22, and it is closed. As a result, a filling space 13 is formed above the holding portion 211 of the red cylinder 2 in the storage cylinder 3, and the melted cosmetic can be filled from above and cooled and solidified into the rod-shaped cosmetic 1 in the container. At this time, the holding ribs 213 of the holding portion 211 function as a retaining and anti-rotation mechanism for the rod-shaped cosmetic 1.

Example 3

[0032] As Example 3, an example of a rearward filling type metal rod-shaped cosmetic dispensing container in which the melted cosmetic is poured from the rear end of the container and cooled and solidified will be described with reference to FIG. 9. The structure and process of the insertion type metal rod-shaped cosmetic dispensing container of Example 1 and the upward filling type metal rod-shaped cosmetic dispensing container of Example 2 described above are the same, but the details of the red cylinder 2, the spiral cylinder 4, and the hakama cylinder 6 are different. The differences will be described below. The holding ribs 213 evenly provided on the inner peripheral wall of the holding portion 211 of the red cylinder 2 are in the same inverted T shape formed by combining circumferential ribs and axial ribs as in Example 2. A large through hole 226 is drilled in the ceiling portion 222 of the leg cylinder 22. Filling holes 61 through which the through hole 226 of the red cylinder 2 can be seen are drilled in the bottom portion 41 of the spiral cylinder 4 and the bottom portion of the hakama cylinder 6. The diameter of the filling hole 61 is φ7.0 mm or more, and a filling nozzle for filling the melted cosmetic is inserted so that it can reach the through hole 226 of the red cylinder 2. As a result, the melted cosmetic can be filled into the filling space formed above the holding portion 211 of the red cylinder 2 in the storage cylinder 3 through the through hole 226 and cooled and solidified into the rod-shaped cosmetic 1 in the container. At this time, the holding ribs 213 of the holding portion 211 also function as a retaining and anti-rotation mechanism for the rod-shaped cosmetic 1.

Industrial Applicability

[0033] In the embodiments of the present invention, as a material for making the metal rod-shaped cosmetic dispensing container into a single material, an aluminum material was used in view of recyclability, press formability, decorativeness, etc. Needless to say, any other metal material that can be press-formed can also be used. In this case, it is necessary to perform a surface treatment according to the metal material used.

[0034] Also, as in the above-described Embodiments 1 to 3, the differences in the container configuration due to the differences in the filling and setting methods of the rod-shaped cosmetics, namely, the shape of the holding rib 213 of the holding portion 211, the shape of the through hole 226, and the presence or absence of the filling hole 61 in the exterior body 12, can be easily implemented by replacing the press working process.

[0035] In Embodiments 2 and 3, the holding rib 213 of the holding portion 211 of the red cylinder 2 has been described as a shape combining ribs in the circumferential direction and the axial direction. However, the shape is not limited to this, and any known shape of the holding rib for the direct filling type can be used. Also, in the case of Embodiment 3, it is also possible to fill the cosmetic beyond the through hole 226 and use the edge of the through hole 226 as a rib for preventing leakage.

[0036] Incidentally, both the holding rib 213 provided on the holding cylinder 21 of the red cylinder 2 and the screwing protrusion 224 provided on the leg cylinder 22 protrude radially from the opposite side surface. However, the timing of this forming can be performed at each timing, not only during the forming process of the red cylinder fabric 20, but also after the surface treatment process, after the cutting process when the holding cylinder 21 and the leg cylinder 22 are divided, and after the assembling process when the red cylinder 2 is formed. Also, the holding rib 213 and the screwing protrusion 224 can be formed at the same timing or at different timings.
