  By the way, when the cosmetic container for storing the bar-shaped cosmetic is composed of a container main body and a cartridge that can be attached to and detached from the container main body, the cartridge can be securely attached to and removed from the container main body while being a simple operation. It is required to be. However, like what is disclosed in Patent Document 1, it is configured to be attached and detached by engagement / disengagement between a concave groove which is an engaging portion on the cartridge side and a convex rib which is an engaging portion on the container body side. Even when there is a slight dimensional error in these concave grooves and convex ribs, smooth engagement / disengagement may be impaired. In other words, if the engagement is loose, there is a problem that the cartridge may fall out of the container body or become glazed while the container is in use, and conversely if the engagement is tightened, the cartridge will be engaged. Inconveniences such as difficulty in operation due to the large force required for removal. Such defective stick-shaped cosmetic containers must be discarded as defective products, which leads to an increase in manufacturing costs, and if it is attempted to manufacture highly accurate products to reduce the number of such defective products, the manufacturing costs are still high. The problem of increasing is generated. In addition, the engagement part wears out while the cartridge is repeatedly engaged and disengaged from the container body, or deformation occurs due to deterioration over time, so that the cartridge and container body can be smoothly engaged and disengaged gradually. The problem of disappearing also arises.

  Moreover, since what is disclosed by patent document 2 is comprised so that a cartridge and a container main body may be attached or detached by the magnetic attachment of a magnet, the malfunction and abrasion by the dimensional error of an engaging part like the thing of patent document 1 are shown. Although there is no problem such as deterioration of function due to deterioration, etc., since the magnet mounting site is the upper end of the engaging rod and the lower end of the cartridge, when replacing the cartridge, the magnet attached to the cartridge and the engaging rod May be exposed to the outside, and the magnetic force generated from the magnet during the replacement operation of the cartridge may unexpectedly affect the surroundings, for example, damage a nearby magnetic card. In addition, since the magnet is provided on the upper end of the engaging rod that moves up and down, the magnet is not only located at the position close to the opening of the container body even when the engaging rod is most immersed, but is also engaged. When the rod is raised, it protrudes upward from the opening of the container main body, and when the cartridge is removed, the surrounding magnetic material is easily attached to the magnet at the upper end of the engaging rod. May cause the cartridge to be unable to be set in a normal posture, and there are problems that the present invention does not solve.

The present invention has been devised in order to solve the above-mentioned problems. The invention of claim 1 is directed to a bottomed cylindrical cartridge filled with a rod-shaped cosmetic material in a bottomed cylindrical container body. In the cartridge-type stick-shaped cosmetic container that is detachably attached, the cartridge is incorporated in a spiral cylindrical body in which a spiral guide is formed in the cylindrical portion, and an inner and outer double cylindrical shape with respect to the spiral cylindrical body. A body cylinder having a longitudinal guide that is long in the axial direction, a double cylinder that is filled with the bar-shaped cosmetic material, and an engagement protrusion that engages with the spiral guide and the longitudinal guide is provided. And a middle dish configured so that the engaging protrusion is guided by the spiral guide and the vertical guide by the relative rotation of the spiral cylinder body and the body cylinder so that the cartridge moves up and down in the cartridge. , Arranged inside the body tube and the spiral tube The body and the container main body are assembled so that relative movement in the insertion / removal direction is allowed, but relative rotation in the circumferential direction is restricted, and a magnet is provided inside the cylinder of the container main body. The cartridge-type bar-shaped cosmetic container is provided at the bottom of the inner cylindrical body with a magnetic body that is attracted by a magnet to support the cartridge on the container body.

According to a fourth aspect of the present invention, in the bar-shaped cosmetic container according to the second aspect, the shielding member is provided on a bottom portion and a cylindrical portion of the container main body.
A fifth aspect of the present invention is the stick-shaped cosmetic container according to the second, third or fourth aspect, wherein a gap is provided between the magnet and the shielding member.

According to the first aspect of the present invention, the magnet for magnetically attaching the cartridge in the container main body is provided inside the cylinder of the container main body, and the magnetic force of the magnet hardly reaches the opening of the container main body. Thus, during the cartridge replacement operation, a nearby magnetic substance does not enter from the opening of the container body and magnetically adhere to the magnet of the container body. In addition, since a magnetic material that is not fielded is provided at the bottom of the cartridge, there is no possibility of magnetically adhering magnetic materials in the vicinity when the cartridge is placed for replacement. Therefore, when the cartridge is attached to the container main body, it is possible to avoid a problem that an extra magnetic substance is magnetically attached to the magnet and the cartridge is not correctly magnetically attached to the container main body.
According to the invention of claim 2, the magnetic force of the magnet provided on the container body by the shielding member does not leak to the outside of the cosmetic container, and the magnetic force affects the surroundings, or the surrounding magnetic substance Is not magnetically attached to the outer surface of the stick-shaped cosmetic container. Therefore, even when, for example, a stick-shaped cosmetic container is put into a drawer or bag, the magnetism of the magnetic card in the vicinity is not damaged or the magnetic substance is not magnetized.
By making it invention of Claim 3, especially the leakage of the magnetic force from the bottom part of a container main body can be prevented.
By setting it as invention of Claim 4, especially the leakage of the magnetic force from both the bottom part of a container main body and a cylinder part can be prevented.

It is supposed to be located.

  The lower surface of the small-diameter portion 7b is a magnet contact surface 7d that comes into contact with the upper surface 6a of the magnet 6 disposed below the magnet holding tube 7, and the lower end of the magnet holding tube 7 extends from the magnet contact surface 7d. Up to the edge 7e is a cylindrical magnet holding portion 7f for holding the magnet 6. The magnet holding portion 7f is formed such that the lower surface 6b of the magnet 6 to be held is flush with the lower end edge 7e of the magnet holding cylinder 7, and the magnet 6 is held in this state. By incorporating the holding cylinder 7 into the flange cylinder 5, the magnet 6 is fixed and supported in a sandwiched manner between the magnet holder 7f and the bottom surface 5b of the flange cylinder 5 with the upper surface 6a viewed from the small diameter portion 7b. It has become.

  The magnet 6 only needs to be able to magnetically attach a later-described attracting member 14 which is a magnetic body attached to the cartridge body 3, and the magnetic poles may be arranged in any manner. For example, an S pole may be disposed on the upper surface and an N pole may be disposed on the lower surface, or vice versa. Moreover, it may be arranged such that the N pole and the S pole are adjacent to each other on the upper surface. In this case, the N pole and the S pole may be arranged one by one, or two or more multipoles may be provided. It may be arranged. That is, the arrangement of the magnetic poles is not limited as long as the magnetic force to magnetically attach the magnetic body provided in the cartridge body 3 is obtained.

  On the other hand, the cartridge body 3 is a cylindrical body in which the cosmetic A protrudes up and down from the opening 3a at the upper end, and spirals on the inner side surface of the cylindrical section inside the gripping cylinder 9 that is the outermost cylindrical body. A spiral cylindrical body 10 in which a groove (corresponding to a “spiral guide” of the present invention) 10 a is engraved is provided so as to be integrated with the gripping cylinder 9 (not relative to rotation). A plurality of (in the present embodiment, a pair of) longitudinal holes (corresponding to the “longitudinal guide” of the present invention) 11a that is long in the axial direction on the peripheral surface portion are spaced apart in the circumferential direction inside the spiral cylinder 10. A bottomed cylindrical body 11 formed in the shape of the cylinder 11 is provided so as to be rotatable relative to the spiral cylinder 10.

A bulge 11b bulging in an outer-diameter ridge shape is formed at the upper end portion of the body cylinder 11, and the bulge portion 11b is assembled with the upper end portion of the spiral cylinder body 10 in contact therewith. Thus, the spiral cylinder 10 is not displaced in the axial direction while maintaining the relative rotation with respect to the body 11.
On the other hand, an annular ring 12 is integrally attached to the outer peripheral surface of the lower end portion of the body 11, and the upper end portion of the ring 12 is incorporated in a state of being in contact with the lower end portion of the spiral cylinder 10.

The vertical hole 11 a is formed on the outer peripheral surface of the inner tray 13. An engaging protrusion 13a that protrudes through and engages with the spiral groove 10a is formed. Then, the spiral groove 10a and the vertical hole 11a are relatively rotated by the relative rotation of the spiral cylinder body 10 and the body cylinder body 11, thereby engaging the spiral groove 10a and the vertical hole 11a. The protrusion 13a is guided up and down by the spiral groove 10a in a state in which the rotation is restricted by the vertical hole 11a, and moves in the vertical and vertical lines in the body 11 so that the inside of the cartridge body 3 of the inner tray 13 can be moved. The cosmetic A filled in the inner tray 13 can be moved up and down through the opening 3 a of the cartridge body 3.

A plurality of longitudinal ribs 11c extending in the vertical axis direction extending to the lower end of the cylindrical portion of the body 11 are formed on the outer peripheral surface of the body 11 below the ring 12 so as to protrude. By engaging the rib 11c with the vertical engagement groove 7a of the magnet holding cylinder 7 provided in the container body 2 described above, the body 11 can be inserted into and removed from the container body 2 in a state in which the rotation is restricted. It is comprised so that.
The lower end portion of the ring 12 is in contact with the upper end portion of the vertical rib 11c, so that the ring 12 is not displaced downward in the axial direction of the cartridge body 3.

  A through hole 11d is formed in the bottom center of the body 11 and a plurality of locking projections 11e are formed in the circumferential direction on the inner peripheral surface of the through hole 11d. An adsorbing member 14 made of a magnetic material (formed of a ferromagnetic material such as iron) is passed through the through hole 11d. The adsorption member 14 has a diameter larger than that of the through hole 11d, and when the cartridge body 3 is incorporated in the container body 2, the adsorption member 14 is fitted into the small-diameter portion 7b of the magnet holding cylinder 7 and the magnet is thereby fitted.

An engaging protrusion for forcibly engaging the locking protrusion 11e formed in the through hole 11d on the upper outer periphery of the through cylinder portion 14b so that it does not fall off from the body 11 14c is formed. The disc body 14 a is magnetically attached to the magnet 6 so that the cartridge body 3 is fixedly supported with respect to the container body 2.

  On the other hand, in the state where the container main body 2 is covered, the bottomed cylindrical cap 4 that covers the container main body opening 8b is in contact with the upper end 5a of the casing 5 and the lower inner peripheral surface 4a. Is in sliding contact with the cap sliding contact portion 8a of the inner tool 8. Further, an inner cap 4c is fitted inside the upper portion of the cap 4, and when the cap 4 covers the container body 2, the upper outer peripheral surface 9a of the gripping cylinder 9 is slidably supported by the inner cap 4c. The cartridge body 3 does not rattle in the container body 2.

  In the embodiment of the present invention configured as described, when the cartridge body 3 is first attached to the container body 2, the lower end side of the cartridge body 3 is inserted from the container body opening 8b, The lower end portion is inserted until it abuts against the cartridge body abutting surface 7c of the magnet holding cylinder 7. Then, the disk portion 14a of the suction member 14 attached to the center of the bottom portion of the body 11 is fitted into the small diameter portion 7b of the magnet holding tube 7 provided in the inner part of the container body 2, thereby attracting the magnet. The disk portion 14a of the member 14 is magnetically attached to the magnet 6 held by the magnet holding portion 7f, and the cartridge body 2 is assembled in the container body 3 in a retaining manner.

  In the state in which the cartridge body 3 is assembled in the container body 2 in this way, the longitudinal ribs 11 c formed on the outer peripheral surface of the lower end portion of the body 11 are formed on the inner peripheral surface of the magnet holding cylinder 7. Since the cartridge body 3 is engaged with the mating groove 7a, the cartridge body 3 can be inserted into and removed from the container body 2, but is attached in a state where the rotation is restricted. In this state where the vertical ribs 11c are engaged with the vertical engagement grooves 7a, the container body 2 and the body 11 rotate together, so that the scissors of the container body 2 with one hand. 5 (or middle tool 8) is gripped, the gripping cylinder 9 of the cartridge body 3 is gripped by the other hand, and the saddle cylinder 5 and the gripping cylinder 9 are rotated relative to each other, the saddle cylinder 5 and the body cylinder 11 and the gripping cylinder 9 and the spiral cylinder body 10 rotate together, so that the spiral cylinder body 10 and the body cylinder body 11 rotate relative to each other. The cosmetic A filled in the inner tray 13 by moving up and down inside the cylindrical body 11 appears and disappears from the cartridge body 3.

  After the cosmetic A is used, the container body 2 and the cartridge body 3 are rotated relative to each other until the cosmetic A sinks to a height at which the cosmetic A does not protrude from the opening 3 a of the cartridge body 3. What is necessary is just to cover the cap 4 from the opening part 3a of the cartridge body 3 until the lower end part 4b contacts the upper end part 5a of the barrel 5.

  On the other hand, when the cosmetic A is used up or when the cartridge body 3 is replaced with one filled with another color of cosmetic, the cap 4 is removed from the container body 2 with one hand. 5 (or the middle tool 8), the gripping cylinder 9 is gripped with the other hand, and the cartridge body 3 is forcibly pulled out from the container body opening 8b, the attracting member 14 resists the magnetizing force with the magnet 6. Then, the cartridge body 3 can be pulled out from the container body 2 by being separated from the magnet 6.

  Accordingly, after the cosmetic has been used up or when another cosmetic is used, the cartridge body 3 that has already been attached is pulled out of the container body 2 and the cartridge body 3 to be newly attached is attached to the container body opening. It is only necessary to insert from 8b until the attracting member 14 provided at the bottom of the cylinder 11 hits the cartridge body abutting surface 7c formed on the magnet holding cylinder 7.

The cartridge-type bar-shaped cosmetic container 1 configured in this manner has a magnet 6 attached to the inner part of the cylinder of the container body 2 and is far from the container body opening 8b, so that the magnetic force at the opening 8b does not reach. As a result, there is no problem that foreign matter is attracted from the container body opening 8b and magnetically attached to the magnet 6 during the replacement of the cartridge body 3, and the disk portion 14a and The regular attachment posture of the cartridge body 3 with respect to the container main body 2 due to the foreign matter magnetized between the magnet 6 and the magnet 6 is not impaired.
Further, since the attracting member 14 provided at the bottom of the cartridge body 3 is a magnetic body that is not fielded, there is no problem that the peripheral magnetic member is inadvertently attracted to the cartridge body 3 at the time of replacement. There is no adverse effect on the magnetic member.
