Description

[Technical field]

[0001] To provide an environmentally friendly container for feeding stick-type cosmetics, which stores stick-type cosmetics such as lipstick and stick foundation, and which can be easily recycled when discarding the stick-type cosmetics after use. [Background technology]

[0002] Conventionally, environmentally friendly stick-type cosmetic containers have generally been disposed of by disassembling the container into resin and metal parts and disposing of them separately. Metal stick-type cosmetic containers are also known, as shown in Patent Document 1. If this type of container is molded from a single material, such as an aluminum alloy, it can be recycled as is without disassembly or separation, reducing waste.

[0003] The metal members of these metal stick-shaped cosmetic containers were mainly formed by pressing. Among them, the red plate that holds the end of the stick-shaped cosmetic penetrates a vertical guideway drilled long in the axial direction on the side wall of the cylindrical body in which it is stored, and has a protrusion that screws into a helical groove screwed into a helical tube that is rotatably held on the outer periphery of the cylindrical storage body. The protrusion screws into the helical groove of the rotating helical tube when the cylindrical storage body and the helical tube rotate relative to each other, preventing it from rotating due to the vertical guideway, and causes the red plate to slide up and down.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 56-158607 Summary of the Invention [Problem to be solved by the invention]

[0005] The tip of this red plate is screwed into the spiral groove, corner portion (Edge part)but Angular This makes it less likely to come off the helical groove. When this red plate was molded, the prongs were molded to protrude outward from the inner wall of the red plate. And since the prongs penetrate the storage cylinder and screw into the helical groove of the helical tube, they need to protrude a little less than twice the thickness of the wall (assuming the red plate, storage cylinder, and helical tube have the same thickness). As a result, The side walls are stretched, The thickness becomes thinner, corner portion (Edge part) of Sharpening the corners There was a risk of it tearing apart. [Means for solving the problem]

[0006] The main components are a red cylinder 2, 12 which holds a stick-shaped cosmetic 1 and has a screw-on protrusion 24 protruding from its side wall, a cylindrical storage body 3, 13 which holds the red cylinder 2, 12 inside so that it can slide up and down and has a long guide slit 32 drilled along its axis in the side wall through which the screw-on protrusion 24 passes and which guides the red cylinder 2, 12 so as to prevent it from rotating, and a helical cylinder 4, 14 which is held rotatably by the cylindrical storage body 3, 13 and has a helical groove 41 formed in its inner wall into which the screw-on protrusion 24 of the red cylinder 2, 12 screws, and all of the components are molded from the same metal material. The number of the screw-on projections 24 of the red tubes 2, 12, the number of the guide slits 32 of the cylindrical storage bodies 3, 13, and the number of the spiral grooves 41 of the spiral tubes 4, 14 are the same. The helical tube 4, 14 has a thin-walled pipe shape, and the helical groove 41 has a groove width narrower than the slit width of the guide slit 32 of the storage cylinder 3, 13. The helical groove 41 is protruded from the inner wall of the helical tube 4, 14 toward the outer periphery from the inner wall to such an extent that a helical groove trace 43 appears on the outer wall of the helical tube 4, 14. The red cylinder 2, 12 is a thin-walled cylinder, and the screwing protrusion 24 is composed of a regulating protrusion 241 that engages with the guide slit 32 and a screwing protrusion 242 that screws into the helical groove 41. The regulating protrusion 241 and the screwing protrusion 242 have diameters that match the slit width of the guide slit 32 and the groove width of the helical groove 41, respectively. The regulating protrusion 241 has a larger diameter, and the screwing protrusion 242 has a smaller diameter and is stacked in two layers in a kagami mochi shape on top of the regulating protrusion 241. The screwing protrusion 24 is protruded from the inner wall of the red cylinder 2, 12 toward the outer periphery, and the edge portion 245 at the tip of the screwing protrusion 242 is sharpened. Mold.

[0007] All of these components are made from aluminum. Effect of the Invention

[0008] As described above, in the present invention, all of the components are made of the same metal material, so that when the container is discarded, it can be recycled as metal material. Therefore, it can be said that this is an environmentally friendly stick-type cosmetic dispenser container that reduces waste. In particular, when aluminum, which is an excellent material for recycling, is used as the metal material, it can be recycled efficiently.

[0009] The guide slit 32 provided in the storage cylinder 3, 13 is wider than the helical groove 41 provided in the helical cylinder 4, 14, and the screw-fitting protrusion 24 of the red cylinder 2, 12 that penetrates the guide slit 32 and screws into the helical groove 41 is composed of a restricting protrusion 241 that engages with the guide slit 32 with a size corresponding to the groove width of the guide slit 32, and a screw-fitting protrusion 242 that screws into the helical groove 41 with a size corresponding to the groove width of the helical groove 41, Large diameter On top of the restricting protrusion 241 Small diameter The screw-engagement protrusion 242 In the shape of a kagami mochi The two-tiered restricting protrusion 241 and the screwing protrusion 242 are formed to protrude from the inner wall toward the outer periphery. Therefore, the protruding amount of each of the two-tiered restricting protrusion 241 and screwing protrusion 242 is approximately the thickness of the metal material. Sidewall stretch This allows for molding with a certain margin, and the tip of the screw-engagement protrusion 242 Edge section 245 of Corner stand As a result, the engagement between the screw-engagement protrusion 242 and the helical groove 41 can be strengthened, and the screw engagement can be made stronger.

[0010] The screw thread 24 and the helical groove 41 are formed by plastic deformation, protruding from the inner wall of the metal sheet toward the outer periphery, so that when the screw thread 24 is screwed into the helical groove 41, the formed surfaces rub against each other, and the rotational feel is not adversely affected. Similarly, the helical groove 41 of the helical tube 4, 14 is formed from the inner wall toward the radial direction, and the unevenness of the helical groove 41 is formed on the outer wall of the helical tube 4, 14. Spiral groove mark 43 Therefore, the depth of the helical groove 41 can be made greater than the thickness of the helical tube 4, 14, and the engagement between the screwing protrusion 242 and the helical groove 41 can be increased, making the screwing stronger.

FIG. Example 1

[0012] An environmentally friendly stick-type cosmetic container according to a first embodiment of the present invention will be described with reference to Figures 1 to 5. The stick-type cosmetic container according to the first embodiment of the present invention comprises a red cylinder 2, a cylindrical storage body 3, a spiral cylinder 4, a middle cylinder 5, a hakama cylinder 6, and a cap 7, and all of the components are formed by pressing or the like from a single metal material such as aluminum.

[0013] The red tube 2 consists of a holding tube 21 and a leg tube 22 that is attached to the lower end of the holding tube 21. The holding tube 21 is shaped like a pipe with open top and bottom ends. The leg tube 22 is cap-shaped with a ceiling portion 221. The upper portion has a reduced outer diameter, forming a fastening portion 222 to which the lower portion of the holding tube 21 is attached. The holding tube 21 and the ceiling portion 221 together form the holding portion 23 that holds the lower end of the stick-shaped cosmetic material 1. A screw-fitting protrusion 24 protrudes from the lower outer wall of the leg tube 22.

[0014] The stick-shaped cosmetic material 1 and the red cylinder 2 are housed inside a cylindrical storage body 3 so as to be vertically slidable. An engagement rib 31 is provided around the middle of the outer periphery of the cylindrical storage body 3, protruding from the inner periphery toward the outer wall. When the stored red cylinder 2 is at its lowest point, the engagement rib 31 is located below the upper end of the red cylinder 2. Below the engagement rib 31, a guide slit 32 is drilled in the axial direction. This guide slit 32 is a groove at the lower end of the cylindrical storage body 3, into which the screw-on protrusion 24 of the red cylinder 2 is inserted and engaged from the lower end, guiding the red cylinder 2 so as to be vertically slidable while restricting it from rotating. Then, as shown in FIG. 3, the screw-on protrusion 24 comes into contact with the upper end of the guide slit 32, and the red cylinder 2 reaches its upper limit. The tip portion of the screw-fitting protrusion 24 protrudes from the side wall of the cylindrical storage body 3, and the portion that engages with the guide slit 32 forms a regulating protrusion 241, and the portion that protrudes from the side wall of the cylindrical storage body 3 forms a screw-fitting protrusion 242.

[0015] The lower part of the cylindrical storage body 3 is rotatably inserted into the helical cylinder 4. The helical cylinder 4 is shaped like a thin cup with a bottom 42, and has a helical groove 41 on its inner wall into which the screwing protrusion 242 of the screwing projection 24 protruding from the side wall of the cylindrical storage body 3 screws. The helical groove 41 is open at its upper end, and the screwing protrusion 242 can be screwed in from the upper end. As shown in Figure 1, the lower end of the red cylinder 2 abuts against the bottom 42 of the helical cylinder 4, which marks the lower limit of the red cylinder 2. Also, as shown in Figure 2, the helical groove 41 is formed on the outer wall rather than the inner wall. Spiral groove mark 43 It is molded by protruding.

[0016] The groove width of the guide slit 32 of the cylindrical storage body 3 is wider than the groove width of the spiral groove 41. Accordingly, the screw-fitting protrusion 24 is formed to have a width corresponding to the groove width of the guide slit 32. Outside diameter The groove width of the spiral groove 41 corresponds to the groove width of the regulating protrusion 241 that engages with the guide slit 32. Outside diameter The screw-engagement protrusion 242 is screwed into the helical groove 41. Large diameter On top of the restricting protrusion 241 , small diameter The screw-engagement protrusion 242 In the shape of a kagami mochi It consists of two overlapping tiers that protrude from the inner wall toward the outer wall, as shown in Figure 2.

[0017] The helical tube 4 is inserted and fixed from below into the middle tube 5. The middle tube 5 is shaped like a pipe with both ends open, and its lower part is inserted and fixed into a bottomed cylindrical hakama tube 6. The upper end of the middle tube 5 protrudes from the upper end of the hakama tube 6 and forms a fitting part 51 into which the cap 7 is detachably fitted. The upper end of this fitting part 51 forms a tip part 52 whose inner diameter is slightly larger than the outer diameter of the cylindrical storage body 3, and a connecting part 53 is formed between the tip of the helical tube 4 and the fitting part 51, which holds the engagement rib 31 of the cylindrical storage body 3 rotatably and non-detachably.

[0018] The above is the configuration of the container for feeding stick-type cosmetic material in Example 1 of the present invention. When the cylindrical storage body 3 is held and the hakama cylinder 6 is rotated, the restricting protrusion 241 of the screw-on projection 24 of the red cylinder 2 engages with the guide slit 32 of the cylindrical storage body 3, so that the container does not rotate. The screw-on projection 242 of the screw-on projection 24 is screwed into the helical groove 41 of the helical cylinder 4, which is fixed to the hakama cylinder 6 via the middle cylinder 5 and rotates, so that the red cylinder 2 slides up and down within the cylindrical storage body 3 due to the screwing action, and the stick-type cosmetic material 1 appears and disappears from the tip of the cylindrical storage body 3.

[0019] In this embodiment, the red tube 2 is configured as two parts, the holding tube 21 and the foot tube 22. However, as shown in FIG. 5, the red tube 2 may be configured as one part. The configuration is described below. The red tube 2 is pipe-shaped with open ends, and has an inner circumferential rib 25 protruding from the inner circumference in the middle. The part above the inner circumferential rib 25 is the holding part 23 that holds the lower end of the stick-shaped cosmetic material 1, and the part below is the foot tube 22 provided with the screw-fitting protrusion 24 consisting of the restricting protrusion 241 and the screw-fitting protrusion 242 described above. This configuration has the advantage that the red tube 2 can be configured as one part. However, since there is a limit to the amount of protrusion of the inner circumferential rib 25 that the lower end of the stick-shaped cosmetic material 1 abuts against, the stick-shaped cosmetic material 1 is not caught easily, and there is a risk that the stick-shaped cosmetic material 1 will slip in if a downward impact is applied to the container, such as when it is dropped upright. Example 2

[0020] Next, an environmentally friendly stick type cosmetic container according to Example 2 of the present invention will be described with reference to Figures 6 to 9. The stick type cosmetic container according to Example 2 of the present invention is composed of a red cylinder 12, a cylindrical storage body 13, a spiral cylinder 14, a middle cylinder 15, a hakama cylinder 16, a cap 17, and a spiral cover 18, and all of the components are formed by pressing or the like from a single metal material such as aluminum.

[0021] The red cylinder 12 is cup-shaped with a bottom, and constitutes a holder 23 that holds the lower end of the stick-shaped cosmetic material 1. A screw-fitting protrusion 24 is provided on the outer wall of the red cylinder 12.

[0022] The stick-shaped cosmetic 1 and the red cylinder 12 are housed in the cylindrical storage body 13 so as to be vertically slidable. An engagement rib 31 is provided on the outer periphery of the upper end of the cylindrical storage body 13. This engagement rib 31 also projects from the inner peripheral wall toward the outer wall. Furthermore, a base 33 whose outer diameter expands to the engagement rib 31 is provided on the lower part of the cylindrical storage body 13, and a holding recess 34 is formed between the engagement ribs 31. A guide slit 32 is drilled in the axial direction in this holding recess 34. The screw-fitting protrusion 24 of the red cylinder 12 penetrates and engages with this guide slit 32, guiding the red cylinder 12 so as to be vertically slidable while restricting it from rotating. The screw-fitting protrusion 24 abuts against the upper and lower ends of the guide slit 32, which respectively indicate the upper limit of the red cylinder 12 as shown in FIG. 8 and the lower limit of the red cylinder 12 as shown in FIG. 6. The tip of the screw-fitting protrusion 24 protrudes from the side wall of the holding recess 34.

[0023] The helical tube 14 is held in the holding recess 34 of the cylindrical storage body 13 so that it can rotate freely and cannot fall off. The helical tube 14 is in the form of a thin pipe with both ends open, and the inner wall is provided with a helical groove 41 into which the screwing protrusion 24 protruding into the holding recess 34 screws. As shown in FIG. 7, the helical groove 41 is formed on the outer wall from the inner wall. Spiral groove mark 43 It is molded by protruding.

[0024] The groove width of the guide slit 32 of the cylindrical storage body 13 is wider than the groove width of the helical groove 41. Accordingly, the screw-fitting protrusion 24 is formed to have a width corresponding to the groove width of the guide slit 32. Outside diameter The groove width of the spiral groove 41 corresponds to the groove width of the regulating protrusion 241 that engages with the guide slit 32. Outside diameter The screw-engagement protrusion 242 is screwed into the helical groove 41. Large diameter On top of the restricting protrusion 241 , small diameter The screw-engagement protrusion 242 In the shape of a kagami mochi It consists of two overlapping tiers that protrude from the inner wall towards the outer wall, as shown in Figure 7.

[0025] The helical tube 14 is inserted from below into the helical cover 18. The helical cover 18 covers the helical tube 14, and its upper end extends up to the upper surface of the cylindrical storage body 13. The upper end of the helical cover 18 is provided with an access hole 81 through which the upper end portions of the stick-shaped cosmetic material 1 and the rouge tube 12 can access.

[0026] The lower part of the cylindrical storage body 13 is inserted into the middle cylinder 15 from above and secured to the lower part of the middle cylinder 15. The middle cylinder 15 is cup-shaped with a bottom, and the lower part is inserted and secured into a bottomed cylindrical hakama cylinder 16. The upper end of the middle cylinder 15 forms a fitting part 51 that protrudes from the upper end of the hakama cylinder 16 and into which the cap 17 is detachably fitted. The upper end of this fitting part 51 covers the lower part of the helical cover 18.

[0027] The above is the configuration of the container for feeding stick-shaped cosmetic material in Example 2 of the present invention. When the helical cover 18 is held and the hakama cylinder 16 is rotated, the red cylinder 12 also rotates because the restricting protrusion 241 of the screw-on projection 24 of the red cylinder 12 engages with the guide slit 32 of the cylindrical storage body 13 that is attached to the hakama cylinder 16 via the middle cylinder 15. And because the screw-on protrusion 242 of the screw-on projection 24 is screwed into the helical groove 41 of the helical cylinder 14 that is attached inside the helical cover 18 and does not rotate, the screwing action causes the red cylinder 12 to slide up and down inside the cylindrical storage body 13, and the stick-shaped cosmetic material 1 appears and disappears through the hole 81 of the helical cover 18. [Industrial Applicability]

[0028] The details of the present invention have been explained in the sections on Examples 1 and 2, but the present invention is not limited to this configuration. It can be implemented as long as the screw-on protrusion 24 of the red tube 2, 12 passes through the guide slit 32 of the storage cylinder 3, 13 and screws into the screw groove 41 of the spiral tube 4, 14.

[0029] The helical groove 41 of the helical tube 4, 14 is formed from the inner wall toward the outer periphery. The forming method may be a molding method using an inner mold such as rolling, or a molding method such as bulging, which uses internal pressure to form the shape of the outer mold. The shape of the helical groove 41 varies slightly depending on the forming method. The screwing protrusion 242 of the screwing protrusion 24 of the red tube 2, 12 is Edge section 245 of Corner stand It goes without saying that the other parts should be shaped to fit the spiral groove 41.

[0030] Specifically, the helical groove 41 of the helical cylinder 4, 14 shown in Figures 2 and 7 is a partially enlarged cross-sectional view of the helical groove 41 formed by rolling. The shape of the helical groove 41 formed by rolling is clearly in accordance with the shape of the inner mold at the time of molding. Angular Correspondingly, the screw-engagement protrusion 242 of the red tube 2, 12 is Edge section 245 teeth , nearly right angle It is shaped like this.

[0031] 10 is a partially enlarged cross-sectional view of the helical groove 14 of the helical cylinder 4 formed by bulging. The shape of the helical groove 14 is formed to the shape of the outer mold by the internal pressure of rubber or the like, and the helical groove 14 on the inner wall Obtuse angle of 90° or more Shape It has become Therefore, the screw-engagement protrusion 242 of the red tube 2 is Obtuse angled The screw-engagement protrusion 242 is formed by combining a cylindrical straight portion 243 and a cone-shaped tapered portion 244 in accordance with the helical groove 14. Edge section 245 of Sharpening the corners, preventing it from falling off from the helical groove 14. In the case of this configuration, the tapered portion 244 of the screw-engaging protrusion 242 comes into contact with the inner wall of the helical groove 14, so that the contact area between the helical groove 14 and the screw-engaging protrusion 242 increases when they are screwed together, allowing for smooth up and down movement.
