Description

  The present invention relates to a method for producing a stick-shaped cosmetic product.

  Various stick-shaped cosmetics such as lipsticks are often used by being mounted on a feeding container having a bottomed cylindrical container generally called a middle dish. The lower end of the stick-shaped cosmetic material molded in advance by a mold or the like is inserted into the inner dish and held. As a method for preventing the stick-shaped cosmetic material from falling out of the inner dish, there is a method of providing a locking rib for holding the stick-shaped cosmetic material inserted into the inner dish on the inner peripheral surface of the inner dish. As the locking rib, a vertical rib installed in parallel with the insertion direction of the bar-shaped cosmetic material is known.

  When the above-described vertical rib is used, the bar-shaped cosmetic material is not sufficiently held and held, and the bar-shaped cosmetic material may fall out of the inner dish. If the protrusion of the rib is inevitably increased if it is to be securely locked, the stick-shaped cosmetic material is likely to be broken or broken when the protrusion of the rib is increased.

  Therefore, for the purpose of preventing the stick-shaped cosmetic from falling out of the inside dish, Patent Document 1 discloses that an air vent hole is formed in the bottom wall of the feeding cylinder corresponding to the middle dish, and the stick-shaped cosmetic is inserted. A check valve having a function of allowing the air in the feeding cylinder to escape outside the feeding cylinder, and a function of preventing the air outside the feeding cylinder from flowing into the feeding cylinder after insertion. A provided stick-shaped cosmetic material supply container has been proposed.

  Similarly to the above, for the purpose of preventing the stick-shaped cosmetic from falling out of the middle dish, Patent Document 2 discloses an exhaust control device that closes the exhaust hole by lowering the middle dish after inserting the stick-shaped cosmetic into the middle dish. There has been proposed a stick-shaped cosmetic container provided with.

JP 2006-204415 A JP 2017-718

  In the technique described in Patent Document 1, after inserting the bar-shaped cosmetic into the feeding cylinder, the air vent hole is closed by the check valve, and the bar-shaped cosmetic is held in the feeding cylinder. However, the check valve in the technique of Patent Document 1 has the air vent hole closed when the insertion of the bar-shaped cosmetic material into the feeding cylinder is completed. For example, the result of checking the appearance of the bar-shaped cosmetic material after insertion of the bar-shaped cosmetic material When it is found that an appearance defect has been found, it is difficult to take a measure of pulling out the bar cosmetic and replacing it with a new bar cosmetic.

  In the technique described in Patent Document 2, the bar-shaped cosmetic is placed in the middle dish without changing the manufacturing process in which the lower end region of the bar-shaped cosmetic is inserted and held in the middle dish and then lowered and stored in the outer cylinder. The exhaust hole is closed by lowering the inner tray after being inserted into the container. Therefore, in the event that an appearance defect of a bar-shaped cosmetic material is discovered, the response to pulling out the bar-shaped cosmetic material and replacing it with a new bar-shaped cosmetic material before the intermediate dish is moved down without changing the manufacturing process. Is possible. However, high precision is required for the dimensions of the members constituting the exhaust control device, and there is a concern that the manufacturing cost of the bar-shaped cosmetic product including these members will increase.

  Therefore, the subject of this invention is providing the manufacturing method of the stick-shaped cosmetics product which can eliminate the fault which the prior art mentioned above has.

The present invention relates to a bottomed cylindrical middle dish having a housing space capable of accommodating the lower end region of a bar-shaped cosmetic, a bar-shaped cosmetic housed in the housing space of the middle dish, and raising and lowering of the middle dish A manufacturing method of a bar-shaped cosmetic product comprising a mechanism and an outer cylinder that accommodates the inner dish, the inner dish having an exhaust hole that communicates the inside and outside of the accommodation space,

  An elevating mechanism 20 for the middle dish 10 is connected to the bottom 12 of the middle dish 10. The elevating mechanism 20 has an elevating base 21. The elevating base 21 has a cylindrical shape, and has a plurality of annular step portions extending along the circumferential direction on the outer peripheral surface thereof. The plurality of annular step portions are formed at a distance along the vertical direction of the elevating base 21. Among the plurality of annular stepped portions, the first stepped portion 21a located on the lowermost side of the main body portion 40 is as shown in FIG. 1 when the elevating mechanism 20 is accommodated in the main body portion 40 described later. It engages with an engaging protrusion 42 projecting from the inner peripheral wall. A second stepped portion 21b is formed at a position above the first stepped portion 21a in the vertical direction. As shown in FIG. 1, the second stepped portion 21 b is engaged with an engaging annular protrusion 31 formed in the lower end region of the outer cylinder 30 in a state where the elevating mechanism 20 is accommodated in the outer cylinder 30 described later. It is supposed to be. A third step portion 21c is formed at a position above the second step portion 21b in the vertical direction. An O-ring 24 is attached to the third step portion 21c as shown in FIG. The O-ring 24 is used to prevent rattling or the like between the outer cylinder 30 and the lifting mechanism 20 when the lifting mechanism 20 is housed in the outer cylinder 30.

  As shown in FIG. 1, the elevation base 21 has a space 21 s at the center when viewed in cross section. This space 21s extends along the vertical direction of the elevating base 21 and is open at the top. A female screw 21d is provided on the inner peripheral wall that defines the space 21s. The first elevating unit 22 is inserted into the space 21s. The 1st raising / lowering part 22 is a member made into the substantially cylindrical shape, and the external thread 22a is provided in the outer surface. The male screw 22a is screwed with the female screw 21d of the elevating base 21 described above. Therefore, when the first elevating part 22 is inserted into the space 21s of the elevating base 21, the first elevating part 22 is rotated around its axis to advance the screwing of the male screw 22a and the female screw 21d. The first elevating part 22 descends as the screwing progresses. By reversing the rotation direction of the first elevating unit 22, the first elevating unit 22 rises. The lowering of the first elevating part 22 is limited by the flange part 22 c provided at the upper end of the first elevating part 22 coming into contact with the stepped part near the upper end of the elevating base part 21.

  As shown in FIG. 1, the first elevating part 22 having a substantially cylindrical shape is provided with a female screw 22 b on an inner peripheral wall defining a space formed therein. The second elevating part 23 is inserted into the space inside the first elevating part 22. The 2nd raising / lowering part 23 is a member made into the substantially column shape, and the external thread 23a is provided in the outer surface. The male screw 23a is screwed with the female screw 22b of the first elevating part 22 described above. When the second elevating part 23 is inserted into the space of the first elevating part 22, the second elevating part 23 is rotated around its axis to advance the screwing of the male screw 23a and the female screw 22b. The second elevating part 23 descends as the screwing progresses. By reversing the rotation direction of the second elevating unit 23, the second elevating unit 23 rises.

  The 2nd raising / lowering part 23 has the exhaust hole 5 extended along an up-down direction in the center area when it sees in cross section. The exhaust hole 5 penetrates the bottom part 12 of the middle dish 10 provided in the upper part of the second elevating part 23 and the upper part of the second elevating part 23 in the vertical direction.

  When the exhaust hole 5 is not closed by the closing member 50 (hereinafter also referred to as a non-closed state of the exhaust hole), the exhaust hole 5 is located inside and outside the accommodation space S in which the lower end region 3a of the bar cosmetic 3 is accommodated. When the lower end region 3a of the bar-shaped cosmetic material 3 is inserted into the accommodation space S of the inner tray 10, the air functions as an air vent hole for discharging the air in the accommodation space S to the outside of the accommodation space S. As shown in FIGS. 1 and 4 (e), in the state where the exhaust hole 5 is closed by the closing member 50 (hereinafter also referred to as the exhaust hole closed state), the flow of air through the exhaust hole 5 is blocked. Thus, the air outside the storage space S is prevented from flowing into the storage space S. The cross-sectional shape of the exhaust hole 5 is circular in the present embodiment, but may be other shapes such as a polygon such as a triangle, a quadrangle, a pentagon, and a hexagon, and an ellipse. Details of the closing member 50 will be described later.

  The bar-shaped cosmetic container 2 includes an outer cylinder 30. As shown in FIGS. 1 and 2, the outer cylinder 30 is a cylindrical member, and the above-described inner tray 10 and the lifting mechanism 20 can be accommodated therein. The lower end of the outer cylinder 30 is located on a plane orthogonal to the axis of the outer cylinder 30. The upper end of the outer cylinder 30 has a circumferential shape of the bottom surface of the oblique cylinder. At the lower end region of the outer cylinder 30, an engaging annular protrusion 31 extending along the circumferential direction of the outer cylinder 30 is formed. The engaging annular protrusion 31 protrudes toward the space inside the outer cylinder 30. As described above, the engaging annular protrusion 31 is engaged with the second step portion 21b of the elevating base 21 of the elevating mechanism 20.

  The bar-shaped cosmetic container 2 includes a main body 40. The main body 40 includes a first main body 44 formed in a substantially cylindrical shape, and a second main body 45 having a bottomed cylindrical shape and having a bottom hole 43. A step is formed between the first main body 44 and the second main body 45. The main body 40 has a space 41 therein. This space 41 extends along the vertical direction of the main body 40, opens at the top, and communicates with the outside of the main body 40 through the bottom hole 43 at the bottom. In the space 41 of the main body 40, the outer cylinder 30, the elevating mechanism 20, and the lower end region 3a of the bar-shaped cosmetic 3 are accommodated. On the inner peripheral wall that defines the space 41 of the main body 40, an engaging projection 42 is projected from the lower end region. As described above, the engaging protrusion 42 is engaged with the first step portion 21a of the lifting base 21 of the lifting mechanism 20.

  The main body 40 is substantially cylindrical in this embodiment, but is not particularly limited as long as it has a structure in which the outer cylinder 30, the lifting mechanism 20, and the lower end region 3 a of the bar-shaped cosmetic 3 are accommodated. For example, the cross section may be oval or the like, or the cross section may be other shapes such as a polygon such as a triangle, a quadrangle, a pentagon, and a hexagon.

  A bottom hole 43 for inserting a closing member 50 (described later) into the main body 40 from the outside is provided in the central area of the lower end of the main body 40. The bottom hole 43 is provided so as to communicate with the inside and outside of the space 21 s of the elevating base 21 and the inside and outside of the exhaust hole 5. From the viewpoint of allowing the closing member 50 to be inserted from the outside of the main body 40 into the main body 40, the diameter of the bottom hole 43 is preferably 100% or more and 200% or less of the maximum outer diameter of the closing member 50, and 100% More preferably, it is 150% or less.

  The closing member 50 closes at least the open end of the exhaust hole 5. As a result, the air flow through the exhaust hole 5 can be blocked, and the insertion state of the bar-shaped cosmetic 3 can be fixed. The shape of the closing member 50 is not particularly limited as long as the air flow through the exhaust hole 5 can be blocked. For example, the closing member 50 may be a plug that can be inserted into the exhaust hole 5. It may be a lid that can be engaged so as to cover the open end.

  Hereinafter, an embodiment in which a plug body that can be inserted into the exhaust hole 5 is used as the closing member 50 will be described with reference to the drawings. In the embodiment described below, the closing member 50 is described as a plug 50.

  FIG. 3A shows a plan view of the plug body 50, and FIG. 3B shows a front view of the plug body 50. The plug body 50 includes a first insertion portion 51 that maintains the circulation of air through the exhaust hole 5 and the bottom hole 43 even when the plug body 50 is inserted into the exhaust hole 5 communicating with the inside and outside of the housing space S, and the exhaust hole. The second insertion portion 52 that blocks the air flow through the exhaust hole 5 and the pedestal portion 53 are provided in this order along the height direction. By inserting the plug body 50 having these structures into the exhaust hole 5 from the first insertion part 51 side through the bottom hole 43, the exhaust hole 5 can be closed.

  As shown in FIGS. 3A and 3B, the first insertion portion 51 is formed in a substantially cylindrical shape elongated in the insertion direction. From the viewpoint of maintaining the air flow through the exhaust hole 5 and the bottom hole 43 even when the first insertion part 51 is inserted into the exhaust hole 5, the first insertion part 51 is provided with the first insertion part 51. Preferably has an outer diameter smaller than the inner diameter of the inner peripheral wall of the second elevating part 23.

  The second insertion part 52 is provided with a plurality of annular ribs 52a that can contact the inner peripheral wall of the second elevating part 23 and close the exhaust hole 5. By providing the plug body 50 with the plurality of annular ribs 52a, the sealing performance of the exhaust hole 5 can be improved. Each of the annular ribs 52 a may be formed with the same outer diameter, or may be formed so that the outer diameter of the annular rib 52 a gradually increases toward the pedestal portion 53. The outer diameter of the annular rib 52a is 100% or more and 110% or less of the inner diameter of the inner peripheral wall of the second elevating part 23 from the viewpoint of being in contact with the inner peripheral wall of the second elevating part 23 and being fixed inside the exhaust hole 5. Preferably, it is more than 100% and 110% or less.

  The stick-shaped cosmetic product 1 can be manufactured by using the stick-shaped cosmetic container 2 having the above configuration and fixing the stick-shaped cosmetic 3 to the container. This manufacturing method will be described with reference to FIGS. 4 (a) to 4 (f).

  First, as shown to Fig.4 (a), the raising / lowering mechanism (not shown) containing the inner tray 10 and the outer cylinder 30 are assembled | attached in the main-body part 40 which has the bottom part hole 43. As shown in FIG. When assembling, the first elevating part 22 and the second elevating part 23 are rotated to bring the inner tray 10 into a state of being fed out, and after the outer cylinder 30 is assembled, the inner dish 10 is lowered. Next, the main body 40 having the bottom hole 43 is further assembled to the lifting mechanism and the outer cylinder 30 in which the inner tray 10 is lowered, and the inner tray 10 is extended.

  Next, as shown in FIG. 4A and FIG. 4B, the lower end region 3 a of the bar-shaped cosmetic material 3 is inserted and accommodated in the accommodation space S of the intermediate dish 10 in the extended state. In this state, since the exhaust holes 5 are not closed, air circulation through the exhaust holes 5 is maintained. Therefore, even when the lower end region 3a of the bar-shaped cosmetic material 3 is inserted into the accommodation space S, the air in the accommodation space S moves through the exhaust hole 5 and the bottom hole 43 as the insertion proceeds. Through the storage space S. These structures are advantageous when the rod-shaped cosmetic 3 is inserted into the accommodation space S while the outer peripheral surface of the lower end region 3 a is in contact with the inner peripheral surface of the intermediate dish 10.

  When the bar-shaped cosmetic 3 is accommodated in the accommodating space S of the inner tray 10, the main body 40 is rotated around the axis while the outer cylinder 30 is held. As a result, as shown in FIG. 4C, the intermediate tray 10 in the extended state is gradually lowered. In this state, since the exhaust hole 5 is not closed, the air flow through the exhaust hole 5 is maintained.

  Subsequently, as shown in FIGS. 4 (d) and 4 (e), the main body portion 40 in a state where the stick-shaped cosmetic 3 is accommodated in the accommodating space S of the intermediate dish 10 and the intermediate dish 10 is lowered most. The plug 50 is inserted from the bottom hole 43 toward the exhaust hole 5 to close the exhaust hole 5. The method for inserting the plug 50 from the bottom hole 43 is not particularly limited. For example, the plug body 50 can be inserted into the exhaust hole 5 by holding the stick-shaped cosmetic container 2 with one hand and pushing the plug body 50 with a hand such as a hand or tweezers. For example, as shown in FIG. 4 (d), the plug-shaped body 50 in which only one part of the plug-shaped body 50 is inserted is held with one hand and protrudes from the bottom of the main body 40. The plug body 50 can be inserted into the exhaust hole 5 by pressing the pedestal portion 53 against a flat plate or the like.

  As shown in FIG. 4 (e), in the state where the plug 50 is inserted into the exhaust hole 5 up to the second insertion portion 52, the air flow through the exhaust hole 5 is blocked. When the flow of air through the exhaust hole 5 is interrupted, the air outside the accommodation space S is prevented from flowing into the accommodation space S through the exhaust hole 5 and the accommodation space through the exhaust hole 5. The air in S is also prevented from flowing out of the accommodation space S.

  By inserting the plug 50 into the exhaust hole 5 and closing the exhaust hole 5, vertical vibrations and the like act on the bar-shaped cosmetic container 2 so that the bar-shaped cosmetic 3 is likely to be separated from the bottom 12 of the inner dish 10. Even if it becomes, since a negative pressure space is formed between the bar-shaped cosmetic 3 and the accommodation space S of the middle dish 10, the bar-shaped cosmetic 3 is difficult to come out of the middle dish 10. Thereby, the lower end region 3a of the bar-shaped cosmetic 3 is stably held in the accommodation space S of the middle dish 10, and the removal from the middle dish 10 of the bar-shaped cosmetic 3 is effectively prevented. In this way, the target bar-shaped cosmetic product 1 is obtained.

  According to the manufacturing method as described above, since the closing member 50 (plug body 50) can be inserted at a desired timing after the stick-shaped cosmetic 3 is inserted into the inner dish 10, Patent Document 2 described above. Unlike the technique described in the above, there is an advantage that the degree of freedom of the closing time of the exhaust hole 5 is increased depending on the specific structure of the bar-shaped cosmetic product.

  In the present embodiment, the bottom hole 43 provided in the main body 40 is in an open state even after the plug 50 is inserted. It is preferable to close the bottom hole 43 from the viewpoint of preventing the closing member 50 from falling out of the main body 40 and preventing foreign matter from entering the elevating mechanism 20. Examples of the method of closing the bottom hole 43 include a method of sticking and sealing an adhesive member such as a seal, and a method of closing with a material that hardens with time, such as a putty.

  As shown in FIG. 4 (d), after the exhaust hole 5 is once closed by the closing member 50, as shown in FIG. 4 (f), the inner tray 10 in which the lower end region 3a of the bar-shaped cosmetic material 3 is accommodated. Even if it is extended again, the closed state of the exhaust hole 5 by the closing member 50 is maintained. Accordingly, when the user uses the stick-shaped cosmetic 3 by paying out the intermediate dish 10 or when the consumer or the like transports or stores the stick-shaped cosmetic 3 in the state where the user or the like has drawn out the intermediate dish 10, Removal from the dish 10 is effectively prevented.

  When the plug body 50 is used as the closing member 50, the length of the plug body 50 in the insertion direction is not particularly limited. However, in the state where the middle plate 10 of the bar-shaped cosmetic product 1 is moved down to the exhaust hole 5, It is preferable that the pedestal portion 53 of the inserted plug 50 has a length that does not protrude from the outer bottom portion of the main body portion 40. For example, the length between the bottom part 12 of the middle dish 10 and the bottom part of the main body part 40 in the state where the middle dish 10 is lowered most can be the length of the plug body 50.

  The annular rib 52a can also function as a mark in the insertion direction of the plug body 50 and a handle in which the annular rib 52a has a non-slip function when the stick-shaped cosmetic product 1 is assembled. In particular, after inserting the stick-shaped cosmetic 3 into the inner tray 10, the plug body 50 can be inserted into the exhaust hole 5 without interrupting the insertion direction of the plug body 50 when blocking the air flow. Thus, the annular rib 52a can improve the workability in the entire manufacturing process of the bar-shaped cosmetic product including the manufacturing process of inserting the plug 50 into the exhaust hole 5.

  Next, second to fourth embodiments of the present invention will be described with reference to FIGS. About these embodiments, it explains focusing on a different point from a 1st embodiment, and explanation about a 1st embodiment is suitably applied to a point which is not explained especially. 5 to 11, the same members as those in FIGS. 1 to 4 are denoted by the same reference numerals.

  In the manufacturing method of the stick-shaped cosmetic product 1A using the plug body 50A shown in FIGS. 6 (a) and 6 (b), the same steps as those shown in FIGS. 4 (a) to 4 (c) described above are performed. The bar-shaped cosmetic product 1A is manufactured in the steps shown in the order of FIGS. 7 (a) and 7 (b).

  When the steps shown in FIGS. 4A to 4C are performed, the stick-shaped cosmetic 3 is stored in the storage space S of the intermediate dish 10 and the intermediate dish 10 is moved down most, as shown in FIG. As shown in a), the plug body 50A is inserted from the bottom hole 43 of the main body 40 toward the exhaust hole 5, and the exhaust hole 5 is closed. Next, as shown in FIG. 7 (b), the plug body 50 </ b> A is rotated around its axis while the plug body 50 </ b> A is inserted into the exhaust hole 5 and the exhaust hole 5 is closed, so that the point 51 a is positioned at the lower end of the bar-shaped cosmetic 3. Screw into the area 3a.

  The method for inserting the plug body 50A from the bottom hole 43 is not particularly limited as in the method for inserting the plug body 50 used in the first embodiment, but the plug body 50A is rotated along the screw provided in the first insertion section 51A. However, it is preferable to insert the plug 50A. Thereby, the state where the lower end region 3a of the bar-shaped cosmetic 3 is inserted into the accommodation space S can be maintained without damaging the bar-shaped cosmetic 3.

  According to the present embodiment, the tip 51a of the plug body 50A bites into the lower end region 3a of the bar-shaped cosmetic material 3 and is screwed together, whereby the pointed portion 51a of the plug body 50A and the lower end region 3a of the bar-shaped cosmetic material 3 are Are in contact with each other, and the accommodation state of the bar-shaped cosmetic 3 is strongly held. Due to this, according to the present embodiment, in addition to the effects exhibited in the first embodiment described above, the lower end region 3a of the bar-shaped cosmetic 3 is more stable in the accommodation space S of the inner dish 10. It is also possible to effectively hold the stick-shaped cosmetic 3 from the middle dish 10 and prevent it from coming off. In this way, the target bar-shaped cosmetic product 1A is obtained.

  8 to 10 show a third embodiment of the present invention.
