Definitions
- the present invention is related to a cosmetic material container. More specifically, the present invention is related to a cosmetic material container equipped with a main body that houses a cosmetic material such as lipstick, a lid member that fits on the main body in a rotatable manner, and a magnet that maintains the main body and the lid member in a fitted state by magnetic force.
- a cosmetic material container equipped with a main body that houses a cosmetic material such as lipstick, a lid member that fits on the main body in a rotatable manner, and a magnet that maintains the main body and the lid member in a fitted state by magnetic force.
- Patent Document 1 In conventional cosmetic material containers constituted by a main body that houses a cosmetic material and a lid member that fits on the main body in a rotatable manner, a technique that mounts magnets on each of a main body and a lid member in order to maintain a fitted state is well known (Patent Document 1).
- Patent Document 2 a technique that provides markings on the outer peripheral surfaces of a main body and a lid member in order to prevent the same magnetic poles facing each other by positioning opposite magnetic poles to face each other during fitting is also a known technique (Patent Document 2). Further, there is also a known technique that provides a stepped portion on a main body and a recessed portion that engages with the stepped portion on a lid member to perform more accurate positioning, because positioning that only utilizes magnetic force may generate a degree of positioning shift.
- the present invention has been developed in view of the foregoing circumstances. It is an object of the present invention to provide a cosmetic material container that maintains a fitted state between a main body and a lid member by magnetic force, that suppresses the leakage of magnetic force, facilitates removal of the lid member from the main body, and facilitates positive positioning of the main body and the lid member at a predetermined position in a rotational direction of the lid member, without sacrificing the pleasant sensation of magnetic attraction by the magnetic force during fitting operations.
- a cosmetic material container of the present invention that achieves the above objective comprises:
- the "lid member which is fitted onto the main body in a relatively rotatable manner” means that one of the lid member and the main body is rotatable with respect to the other in a state in which the main body and the lid member are fitted.
- This configuration is not limited to that in which one is fixed and the other is rotated, and a configuration in which both the main body and the lid member rotate is also possible.
- the abutment surfaces are configured to separate and approach each other between a position at which the main body and the lid member are positioned at the predetermined position in the rotational direction of the lid member such that the abutment surfaces abut each other, and the position other than the predetermined position at which the main body and the lid member are separated in the direction of the rotational axis thereof by relative rotation of the main body and the lid member.
- the main body and the lid member may be configured such that a recessed portion is formed on one of the abutment surfaces and a protruding portion that abuts the recessed portion is formed the other of the abutment surfaces, and separate from each other by the recessed portion riding up on the protruding portion due to the relative rotation.
- “separate” means that the main body and the lid member move away from each other
- “separate and approach” means that the main body and the lid member move away from and abut each other.
- the main body and the lid member are in a relationship in which the protruding portion formed on the abutment surface of one of the two moves in a sliding direction along the recessed portion, which is formed on the abutment surface on the abutment surface of the other, along an arc having the rotational axis as the center, by the lid member being rotated with respect to the main body.
- the lid member can be separated from the main body, by rotating the lid member with respect to the main body.
- a plurality of combinations of the recessed portion and the protruding portion may be provided along the arc having the rotational axis as the center.
- the main body may be a cylinder, and a cosmetic material which is capable of being fed out, lipstick, for example, may be housed in the cylinder.
- the outer peripheral surface of the lid member and the outer peripheral surface of a base end portion of the main body may be coplanar in the fitted state.
- the cross sectional shape of the main body and the lid member in a direction perpendicular to the rotational axis may be linearly symmetrical with respect to one line.
- the cosmetic material container of the present invention may be equipped with a plurality of sets of magnets.
- a “set of magnets” refers to a combination of an S pole of one magnet provided at the abutment surface of the main body, and an N pole of another magnet provided at the abutment surface of the lid member.
- one of the set of magnets at a first one of the corresponding abutment surfaces prefferably have an N pole facing a second abutment surface and for the other of the set of magnets at the second abutment surface to have an S pole facing the corresponding first abutment surface. That is, it is desirable for magnetic poles of the same polarity to be exposed on the same abutment surface.
- the magnetic force that leaks from the set of magnets in the fitted state it is desirable for the magnetic force that leaks from the set of magnets in the fitted state to be 500 gauss or less.
- the cosmetic material container maintains the fitted state between the main body and the lid member by magnetic force.
- the abutment surfaces of the main body and the lid member that abut each other during a fitting operation are configured to separate and approach each other between the position at which the main body and the lid member are positioned at the predetermined position in a rotational direction of the lid member such that the abutment surfaces abut each other, and the position other than the predetermined position at which the main body and the lid member are separated in a direction of the rotational axis.
- the lid member is movable between a fitted position at which the abutment surfaces abut each other and the main body and the lid member are maintained in a fitted state by magnetic force, and a separated position at which the abutment surfaces are in the position other than the predetermined position, separated from each other against the magnetic force, by rotating the lid member. Therefore, positioning is not performed only by magnetic force, and it is not necessary for the magnetic force of the magnets to be great. As a result, removal of the lid member from the main body is facilitated, and accurate positioning of the main body and the lid member at the predetermined position in the rotational direction is also facilitated.
- a user will experience a sensation that positioning and fitting are automatically performed without sacrificing the pleasant sensation of magnetic attraction by the magnetic force during fitting operations, because if the main body is held and the lid member is rotated, the lid member will be fitted at the predetermined position by magnetic attraction of the magnetic force when the lid member is at a position close to the predetermined position.
- the cosmetic material container 1 houses a cosmetic material for lips (including lipstick, lip color, lip liner, lip cream, lip gloss, and lip essence) in the form of a stick.
- a cosmetic material for lips including lipstick, lip color, lip liner, lip cream, lip gloss, and lip essence
- the cosmetic material container of the present invention is not limited to housing a cosmetic material for lips, and may be applied to any cosmetic material container that houses any cosmetic material, as long as the cosmetic material container is that of an aspect having a main body and a lid member having a fitting portion which is rotatable.
- the cosmetic material container of the present invention may be applied to cosmetic material containers of the dispenser type and the pump type.
- the cosmetic material container 1 is constituted mainly by a main body 2, and a lid member 3 which is fitted on the main body 2 in a manner rotatable about a rotational axis AX.
- Figure 1 illustrates a state in which the lid member 3 is fitted on the main body 2
- Figure 2 illustrates a state in which the lid member 3 and the main body 2 are separated.
- Figure 3 is a plan view of the main body 2
- Figure 4 is a bottom view of the lid member 3.
- the main body 2 is mainly constituted by a columnar portion 21 that houses lipstick, which is not illustrated, and a base end portion 22 having a greater outer dimension than the outer diameter of the columnar portion 21.
- the columnar portion 21 is a cylinder having an opening 211 at the upper end thereof. The lipstick is inserted into the columnar portion 21 through the opening 211, and is contained therein.
- the base end portion 22 is relatively rotatable with respect to the columnar portion 21.
- the cosmetic material container 1 is equipped with a known feeding mechanism that enables the lipstick, which is not illustrated, to be fed out from the opening 211 by rotating the base end portion 22 while holding the columnar portion 21.
- the lid member 3 is a bottomed cylinder.
- a penetrating aperture 31 for the columnar portion 21 to penetrate through is formed in the lower end of the lid member 3 (the lid member is illustrated inverted in the vertical direction in Figure 2 ).
- the shapes of the outer peripheral surfaces of the base end portion 22 of the main body 1 and the lid member 2 are substantially the same, particularly at a fitting portion, and in the fitted state illustrated in Figure 1 , the entirety of the cosmetic material container 1 is of an integrated shape.
- the outer peripheral surface of the lid member 1 may become as narrow as possible toward the upper end thereof, or may be a design that deviates from a circular shape.
- the cosmetic material container 1 is fitted together by a stepped surface 222 that constitutes the upper end of the base end portion 22 and a bottom end surface 33 of the lid member 3 abutting each other.
- a stepped surface 222 that constitutes the upper end of the base end portion 22 and a bottom end surface 33 of the lid member 3 abutting each other.
- the outer peripheral surface 221 of the base end portion 22 and the outer peripheral surface 32 of the lid member 3 become coplanar in the fitted state.
- the stepped surface 222 and the end surface 33 correspond to the "abutment surfaces" recited in the claims.
- the contours of the cross sections perpendicular to the height direction, that is, the direction of the rotational axis AX, of the base end portion 22 and the lid member 3 are non circular shapes having a plurality of continuous arcs having different curvatures. These cross sections are linearly symmetrical with respect to only one line that intersects the rotational axis AX. That is, the cross sections are not symmetrical with respect to two or more lines.
- Such contours of the cross sectional shapes include a heart shape, a crescent moon shape, an isosceles triangle, etc., in addition to the shapes illustrated in Figure 3 and Figure 4 .
- the contours of the cross sections may be designed as other arbitrary shapes that satisfy the above condition regarding symmetry.
- the cosmetic material container 1 prefferably has one or fewer lines L of linear symmetry (having zero lines L of linear symmetry means that a shape is asymmetrical in all directions). The reason why the number of lines L of linear symmetry is set to only one is due to preference as well as aesthetics.
- the cosmetic material container of the present invention includes those having cross sectional shapes with two lines L of linear symmetry, such as rectangles and ellipses, those having cross sectional shapes with three lines L of linear symmetry, such as an equilateral triangle, those having cross sectional shapes with four lines L of linear symmetry, such as a square, and those having cross sectional shapes with an infinite number of lines L of linear symmetry, such as a circle.
- two main body magnets 23 are mounted on the stepped surface 222 at a predetermined angular interval other than 180 degrees along a circumferential direction having its center on the rotational axis AX.
- two lid member magnets 34 are mounted on the end surface 33 at positions at the same predetermined angular interval along the circumferential direction having its center on the rotational axis AZ that cause the main body magnets 23 to face the lid member magnets 34 at a fitting position.
- the two main body magnets 23 and the two lid member magnets 34 have opposite magnetic poles facing each other at the fitting positions such that they will be magnetically attached.
- the main body magnets 23 and the lid member magnets 34 maintain the main body 2 and the lid member 3 in the fitted position by magnetically attaching to each other.
- a combination of the main magnet 23 and the lid member 34 at a position at which opposite magnetic poles face each other is a set of magnets.
- the magnetic poles of the two main body magnets 23 are both N
- the magnetic poles of the two lid member magnets 34 are both S.
- the main body 2 and the lid member 3 both have magnets with the same magnetic poles facing (exposed at) the surface.
- the magnetic poles may not be the same, and may be opposite poles. That is, one of the two main body magnets 23 may have an N pole exposed at the abutment surface while the other main body magnet 23 may have an S pole exposed at the abutment surface, and the one of the two lid member magnets 34 that faces the main body magnet 23 with the exposed N pole may have an S pole exposed at the abutment surface while the other lid member magnet 34 that faces the main body magnet 23 with the exposed S pole may have an N pole exposed at the abutment surface.
- the polarities of magnets must be changed when embedding the magnets according to the position thereof during assembly. Therefore, it is desirable for the magnets to be embedded with the same orientation as in the embodiment illustrated in the drawings.
- the number of the sets of magnets is not limited to two, and it is necessary for at least one or more sets to be provided. However, in the case that only one set is provided, there is a possibility that the magnetic force that leak from the cosmetic material container 1 will become locally strong. Therefore, it is desirable for at least two sets of magnets to be provided, so as to distribute the magnetic force that leaks.
- the positions at which the main body magnets 23 and the lid member magnets 34 are mounted are not limited to the stepped surface 222 and the end surface 33.
- the main body magnets 23 may be mounted on an outer peripheral surface 212 of the columnar portion 21, and the lid member magnets 34 may be mounted on an inner peripheral surface 35 of the lid member 3.
- the main body magnets 23 and the lid member magnets 34 are substantially circular in shape, but the shape of the magnets is not particularly limited.
- the magnets may be rectangular, ring shaped, etc.
- the main body magnets 23 and the lid member magnets 34 are mounted at positions which are linearly symmetrical with respect to the line L of linear symmetry, but the positions at which the magnets are mounted are not particularly limited.
- the magnets may be provided at any position as long as opposite magnetic poles face each other in the fitted state.
- a plurality of fitting positions at which the outer peripheral surface 221 and the outer peripheral surface 32 become coplanar will exist.
- the positions at which the main body magnets 23 and the lid member magnets 34 are mounted may be positions at which opposite magnetic poles face each other in different fitting positions.
- the main body magnets 23 and the lid member magnets 34 are mounted such that opposite poles face each other only at the specific fitting position.
- all of the main body magnets 23 are mounted such that N poles face the end surface 33 during fitting operations.
- all of the lid member magnets 34 are mounted such that S poles face the stepped surface 222 during fitting operations.
- the magnets may be mounted with poles opposite those of the present embodiment, that is, such that the S poles of all of the main body magnets 23 face the end surface 33 and the N poles of all of the lid member magnets 34 face the stepped surface 222 during fitting operations.
- steps during manufacture can be reduced and costs can be decreased, by mounting the magnets such that the directions of the magnetic poles are aligned compared to mounting the magnets such that S poles and N poles alternate, as described previously.
- magnets that leak 500 gauss or less of magnetic force as measured by a known method that employs a known magnetic force sensor in the fitted state to be employed as the main body magnets 23 and the lid member magnets 34, in order to prevent adverse influence from being imparted onto objects which are influenced by magnetic force, such as cards and memories when the cosmetic material container 1 is placed in bags or pockets.
- the widths of the stepped surface 222 and the end surface 33 may be increased to increase the distance from the magnets to the outer peripheral surface of the cosmetic material container 1, or the magnets may be distributed, even if strong magnets are employed.
- the stepped surface 222 includes two protruding portions 223 which are formed on the stepped surface 222.
- the end surface 33 includes two smoothly recessed portions 331 which are formed in the end surface 33. The protruding portions 223 and the recessed portions 331 engage each other at the fitting position.
- Figures 5A through 5D are diagrams that illustrate the transition between fitting and separation of the protruding portions 223 and the recessed portions 331.
- the protruding portions 223 have curved surfaces which are ridged with respect to the stepped surface 222 other than the protruding portions 223.
- the recessed portions 331 have curved surfaces which are recessed with respect to the end surface 33 other than the recessed portions 331.
- the curved surfaces of the protruding portions 223 are follower surfaces 224, and the curved surfaces of the recessed portions 331 are cam surfaces 332.
- the main body 2 and the lid member 3 relatively move in a direction to approach each other along the rotational axis AX while rotating relative to each other, by the cam mechanism formed by the combination of the cam surfaces 332 and the follower surfaces 224, as well as the operation of the set of magnets.
- the follower surfaces 224 slide along the cam surfaces 332 against the magnetic force (refer to Figure 5D ).
- the force that relatively rotates the lid member 20 about the rotational axis AX is converted to a force that separates the main body 2 and the lid member in the direction of the rotational axis AX by the operation of the cam mechanism described above.
- the follower surfaces 224 ride up on the cam surfaces 332, and the main body 2 and the lid member 3 are separated from each other.
- the sensation felt by fingers that rotate the lid member 3 at this time is a feeling that requires a force to rotate the lid member 3 against the magnetic force, and a feeling of an urging force that urges the lid member 3 to return to the fitting position by the magnetic force if the fingers are released.
- the cam mechanism described above is not limited to a combination of the protruding portions 223 of the main body 2 and the recessed portions 331 of the lid member 3.
- the end surface 33 of the line member 3 may have protruding portions 333
- the stepped surface 222 may have recessed portions 225.
- Curved surfaces of the protruding portions 333 may be follower surfaces 334 and curved surfaces of the recessed portions 225 may be cam surfaces 226.
- the follower surfaces 224 and the cam surfaces 332 are not limited to curved surfaces. As illustrated in Figure 7 , the follower surfaces 224 may be surfaces which are inclined with respect to the stepped surface 222 other than the protruding portions 223, and the cam surfaces 332 may be surfaces which are inclined with respect to the end surface 33 other than the recessed portions 331. Note that use of inclined surfaces may also be applied to the follower surfaces 334 and the cam surfaces 226 (refer to Figure 6 ) as well. In this case, the respective surfaces will not be smooth as a whole. However, if the inclined surface of the recessed portion 331, which is formed in the end surface 33, adjacent to the end surface 33 is a gradual inclined surface, the follower surfaces 334 will follow and be easily guided into the recessed portions 331, and therefore smooth movement will be secured.
- the shapes of the follower surfaces 224 and the cam surfaces 332 are not particularly limited. Any shapes may be adopted, as long as at least portions thereof complement each other substantially without gaps when the shapes engage each other. The same applies to the follower surfaces 334 and the cam surfaces 226 (refer to Figure 6 ) as well.
- One protruding portion 223 and one recessed portion 331 may be provided, as illustrated in Figure 8 .
- the sizes of the two protruding portions 223 and the two recessed portions 331 may largely differ, as illustrated in Figure 9 .
- four protruding portions 223 and four recessed portions 331 may be provided, that is, a plurality of pairs of protruding portions and recessed portions may be provided, as illustrated in Figure 10 .
- the present invention may be applied to a cosmetic material container 6 constituted by a cylindrical main body 4 and a lid member 5 which fits onto the main body 4 in a rotatable manner about a rotational axis B.
- Protruding portions or recessed portions may be formed on a stepped surface 41 of the main body 4, and recessed portions or protruding portions may be formed on an end surface 51 of the lid member.
- Figure 12 is a table that shows the results of various comparative measurements which were conducted on a cosmetic material container (E) of the present invention and other cosmetic material containers (A through D) of the type that maintain fitted states by sets of magnets.
- the items of measurement are: a force (N) necessary to remove the lid members from the main bodies by pulling the lid members in the height direction without rotation; a force necessary to remove the lid members by pulling the lid members while rotating the lid members (units are Newton: N); and magnetic force that leaks in a fitted state (units are gauss: G).
- the cosmetic material containers A through C are not equipped with cam mechanisms constituted by protruding portions and recessed portions, and have configurations that maintain fitting only by magnets.
- the cosmetic material container A is that in which a set of ring shaped magnets are mounted
- the cosmetic material container B is that in which two sets of columnar magnets are mounted
- the cosmetic material container C is that in which four sets of columnar magnets are mounted.
- the cosmetic material container D is that in which four sets of columnar magnets are mounted, and further has a positioning structure constituted by protruding portions and recessed portions.
- This positioning structure is a simple engagement between protrusions and recesses, and if rotation of the lid member is attempted, the protruding portions and the recessed portions do not slide with each other, but rather suppress relative rotating motion of the lid member with respect to the main body in the fitted state.
- the cam mechanism formed by the cam surfaces 332 (recessed portions) and the follower surfaces (protruding portions) 224 cause the main body 2 and the lid member 3 to approach each other or separate from each other in response to rotation of the main body 2 with respect to the lid member 3 in the axial direction of the rotational axis AX. Therefore, smooth fitting and removal can be realized. In addition, fitting operations while receiving magnetic force and removal against the magnetic force impart a favorable sense of use, a sense of richness, and a sense of class to users.
- the cosmetic material container of the present invention may be applied to containers that house a cosmetic material for the eyebrows and eyes, such as eyeliner, mascara, eye shadow, and an eyebrow pencil/liner.
- the cosmetic material container of the present invention may also be applied to containers that house a liquid or a semiliquid cosmetic material as an external preparation for skin.
- the follower surfaces 224 and the cam surfaces 332 provided on the abutment surfaces 222 and 33 of the main body 2 and the lid member 3 are provided at an interval (180 degrees, for example) along an arc having the rotational axis AX at its center.
- the cam surface (step) may be a surface that rises throughout the entirety of a 360 degree angular range. Such an embodiment is illustrated in Figure 13 .
- FIG. 13 illustrates a third embodiment of the present invention.
- a cosmetic container of the third embodiment is constituted by a main body 12 and a lid member 13 which are coaxial with the rotational axis AX, and a push type discharge unit 12B that discharges a cosmetic material is fixed on a base end portion 12A of the main body.
- the main body 12 and the lid member 13 are of different shapes of which the cross sectional shapes perpendicular to the rotational axis AX are not circular but symmetrical with respect to one axis.
- the position at which the lid member is fitted onto the main body is clearly discernable from the outer shapes thereof.
- a step 14 which is the same shape as an upper surface 12C of the base end portion 12A and is smaller than the upper surface 12C is formed on the upper surface 12C.
- the discharge unit 12B is fixed on the step 14.
- the step 14 has a deformed triangular upper surface 14B which is surrounded by an inclined surface 14A which is the side surface of the step 14.
- the lid member 13 is equipped with an abutment surface 13A that abuts the upper surface 12C of the base end portion 12A of the main body when fitted thereon, a recess 13B for accommodating the step 14 of the main body 12, and a housing hole 13C having a circular cross section for accommodating the discharge unit 12B.
- the inner surface of the recess 13B is formed to accommodate the step 14 substantially along the outer surface of the step 14.
- magnets that attract each other are embedded in the abutment surfaces 12C and 13A of the main body 12 and the lid member 13, or in the outer surface of the step 14 and the inner surface of the recess 13B.
- the lid member 13 When the cosmetic material container of the third embodiment is opened and closed, if the lid member 13 is rotated with respect to the main body 12 in a fitted state, the lid member 13 rides up on the step 14 of the main body 12 to separate from the main body 12.
- the lid member 13 When fitting the lid member 13 onto the main body 12, if the lid member 13 is fitted onto the main body 12 according to the outer shapes thereof, the lid member 13 is positioned along the inclined surface of the step 14, and simultaneously attracted into the fitting position by magnetic force.
- 14A functions as a cam surface.
- the present invention is not particularly limited to the embodiments described above, and may be modified as appropriate as long as such modifications do not stray from the spirit of the present invention.

- In conventional cosmetic material containers constituted by a main body that houses a cosmetic material and a lid member that fits on the main body in a rotatable manner, a technique that mounts magnets on each of a main body and a lid member in order to maintain a fitted state is well known (Patent Document 1).
- In cosmetic material containers provided with fit maintaining magnets, a technique that provides markings on the outer peripheral surfaces of a main body and a lid member in order to prevent the same magnetic poles facing each other by positioning opposite magnetic poles to face each other during fitting is also a known technique (Patent Document 2). Further, there is also a known technique that provides a stepped portion on a main body and a recessed portion that engages with the stepped portion on a lid member to perform more accurate positioning, because positioning that only utilizes magnetic force may generate a degree of positioning shift.

Japanese Unexamined Utility Model Publication No.S57-187117 - [Patent Document 2]
Japanese Patent No.5480553 - It is necessary to employ magnets having strong magnetic force if positioning is performed utilizing only magnetic force, as in
Patent Document 1 andPatent Document 2. Therefore, a strong pulling force will be necessary when removing the lid member from the main body, and there is a problem that removal will be difficult. - In addition, there are many cases in which cosmetic material containers are carried in bags or the like. If the magnetic force that leaks from the cosmetic material container is strong, there is a possibility that various electronic devices and various magnetic strip card which are in the same bag will be influenced by the magnetic force. However, the above patent documents neither disclose nor suggest suppressing magnetic force from leaking from the cosmetic material containers, or to facilitate removal of the lid members form the main bodies.
- The present invention has been developed in view of the foregoing circumstances. It is an object of the present invention to provide a cosmetic material container that maintains a fitted state between a main body and a lid member by magnetic force, that suppresses the leakage of magnetic force, facilitates removal of the lid member from the main body, and facilitates positive positioning of the main body and the lid member at a predetermined position in a rotational direction of the lid member, without sacrificing the pleasant sensation of magnetic attraction by the magnetic force during fitting operations.
- A cosmetic material container of the present invention that achieves the above objective comprises:
- a main body that houses a cosmetic material;
- a lid member which is fitted onto the main body in a relatively rotatable manner; and
- at least one set of magnets that maintain a fitted state between the main body and the lid member;
- the main body and the lid member respectively having abutment surfaces that abut each other during a fitting operation;
- the abutment surfaces being configured to separate and approach each other between a position at which the main body and the lid member are positioned at a predetermined position in a rotational direction of the lid member such that the abutment surfaces abut each other, and a position other than the predetermined position at which the main body and the lid member are separated in a direction of a rotational axis;
- the lid member being movable between a fitted position at which the abutment surfaces abut each other and the main body and the lid member are maintained in a fitted state by magnetic force, and a separated position at which the abutment surfaces are in the position other than the predetermined position, separated from each other against the magnetic force, by rotating the lid member.
- Here, the "lid member which is fitted onto the main body in a relatively rotatable manner" means that one of the lid member and the main body is rotatable with respect to the other in a state in which the main body and the lid member are fitted. This configuration is not limited to that in which one is fixed and the other is rotated, and a configuration in which both the main body and the lid member rotate is also possible.
- The abutment surfaces are configured to separate and approach each other between a position at which the main body and the lid member are positioned at the predetermined position in the rotational direction of the lid member such that the abutment surfaces abut each other, and the position other than the predetermined position at which the main body and the lid member are separated in the direction of the rotational axis thereof by relative rotation of the main body and the lid member. The main body and the lid member may be configured such that a recessed portion is formed on one of the abutment surfaces and a protruding portion that abuts the recessed portion is formed the other of the abutment surfaces, and separate from each other by the recessed portion riding up on the protruding portion due to the relative rotation. Here, "separate" means that the main body and the lid member move away from each other, and "separate and approach" means that the main body and the lid member move away from and abut each other.
- That is, the main body and the lid member are in a relationship in which the protruding portion formed on the abutment surface of one of the two moves in a sliding direction along the recessed portion, which is formed on the abutment surface on the abutment surface of the other, along an arc having the rotational axis as the center, by the lid member being rotated with respect to the main body. Thereby, the lid member can be separated from the main body, by rotating the lid member with respect to the main body.
- In addition, in the cosmetic material container of the present invention, a plurality of combinations of the recessed portion and the protruding portion may be provided along the arc having the rotational axis as the center.
- In addition, in the cosmetic material container of the present invention, the main body may be a cylinder, and a cosmetic material which is capable of being fed out, lipstick, for example, may be housed in the cylinder.
- In addition, in the cosmetic material container of the present invention, the outer peripheral surface of the lid member and the outer peripheral surface of a base end portion of the main body may be coplanar in the fitted state.
- In addition, in the cosmetic material container of the present invention, the cross sectional shape of the main body and the lid member in a direction perpendicular to the rotational axis may be linearly symmetrical with respect to one line.
- In addition, the cosmetic material container of the present invention may be equipped with a plurality of sets of magnets.
- Here, a "set of magnets" refers to a combination of an S pole of one magnet provided at the abutment surface of the main body, and an N pole of another magnet provided at the abutment surface of the lid member.
- In addition, in the cosmetic material container of the present invention, it is desirable for one of the set of magnets at a first one of the corresponding abutment surfaces to have an N pole facing a second abutment surface and for the other of the set of magnets at the second abutment surface to have an S pole facing the corresponding first abutment surface. That is, it is desirable for magnetic poles of the same polarity to be exposed on the same abutment surface.
- In addition, in the cosmetic material container of the present invention, it is desirable for the magnetic force that leaks from the set of magnets in the fitted state to be 500 gauss or less.
- According to the cosmetic material container of the present invention, the cosmetic material container maintains the fitted state between the main body and the lid member by magnetic force. The abutment surfaces of the main body and the lid member that abut each other during a fitting operation are configured to separate and approach each other between the position at which the main body and the lid member are positioned at the predetermined position in a rotational direction of the lid member such that the abutment surfaces abut each other, and the position other than the predetermined position at which the main body and the lid member are separated in a direction of the rotational axis. The lid member is movable between a fitted position at which the abutment surfaces abut each other and the main body and the lid member are maintained in a fitted state by magnetic force, and a separated position at which the abutment surfaces are in the position other than the predetermined position, separated from each other against the magnetic force, by rotating the lid member. Therefore, positioning is not performed only by magnetic force, and it is not necessary for the magnetic force of the magnets to be great. As a result, removal of the lid member from the main body is facilitated, and accurate positioning of the main body and the lid member at the predetermined position in the rotational direction is also facilitated.
- A user will experience a sensation that positioning and fitting are automatically performed without sacrificing the pleasant sensation of magnetic attraction by the magnetic force during fitting operations, because if the main body is held and the lid member is rotated, the lid member will be fitted at the predetermined position by magnetic attraction of the magnetic force when the lid member is at a position close to the predetermined position.

Figure 13 ] a perspective view that illustrates a cosmetic material container according to a third embodiment of the present invention. - Hereinafter, a
cosmetic material container 1 according to an embodiment of the present invention will be described in detail with reference to the attached drawings. Thecosmetic material container 1 houses a cosmetic material for lips (including lipstick, lip color, lip liner, lip cream, lip gloss, and lip essence) in the form of a stick. Note that the cosmetic material container of the present invention is not limited to housing a cosmetic material for lips, and may be applied to any cosmetic material container that houses any cosmetic material, as long as the cosmetic material container is that of an aspect having a main body and a lid member having a fitting portion which is rotatable. For example, the cosmetic material container of the present invention may be applied to cosmetic material containers of the dispenser type and the pump type. - As illustrated in
Figure 1 through Figure 4 , thecosmetic material container 1 is constituted mainly by amain body 2, and alid member 3 which is fitted on themain body 2 in a manner rotatable about a rotational axis AX.Figure 1 illustrates a state in which thelid member 3 is fitted on themain body 2, andFigure 2 illustrates a state in which thelid member 3 and themain body 2 are separated. In addition,Figure 3 is a plan view of themain body 2, andFigure 4 is a bottom view of thelid member 3. - As illustrated in
Figure 2 , themain body 2 is mainly constituted by acolumnar portion 21 that houses lipstick, which is not illustrated, and abase end portion 22 having a greater outer dimension than the outer diameter of thecolumnar portion 21. Thecolumnar portion 21 is a cylinder having anopening 211 at the upper end thereof. The lipstick is inserted into thecolumnar portion 21 through theopening 211, and is contained therein. - In the
cosmetic material container 1, thebase end portion 22 is relatively rotatable with respect to thecolumnar portion 21. Thecosmetic material container 1 is equipped with a known feeding mechanism that enables the lipstick, which is not illustrated, to be fed out from theopening 211 by rotating thebase end portion 22 while holding thecolumnar portion 21. - As illustrated in
Figure 2 , thelid member 3 is a bottomed cylinder. A penetratingaperture 31 for thecolumnar portion 21 to penetrate through is formed in the lower end of the lid member 3 (the lid member is illustrated inverted in the vertical direction inFigure 2 ). The shapes of the outer peripheral surfaces of thebase end portion 22 of themain body 1 and thelid member 2 are substantially the same, particularly at a fitting portion, and in the fitted state illustrated inFigure 1 , the entirety of thecosmetic material container 1 is of an integrated shape. Of course, the outer peripheral surface of thelid member 1 may become as narrow as possible toward the upper end thereof, or may be a design that deviates from a circular shape. - The
cosmetic material container 1 is fitted together by a steppedsurface 222 that constitutes the upper end of thebase end portion 22 and abottom end surface 33 of thelid member 3 abutting each other. As illustrated inFigure 1 , the outerperipheral surface 221 of thebase end portion 22 and the outerperipheral surface 32 of thelid member 3 become coplanar in the fitted state. The steppedsurface 222 and theend surface 33 correspond to the "abutment surfaces" recited in the claims. - As is clear from
Figure 3 and Figure 4 , the contours of the cross sections perpendicular to the height direction, that is, the direction of the rotational axis AX, of thebase end portion 22 and thelid member 3 are non circular shapes having a plurality of continuous arcs having different curvatures. These cross sections are linearly symmetrical with respect to only one line that intersects the rotational axis AX. That is, the cross sections are not symmetrical with respect to two or more lines. Such contours of the cross sectional shapes include a heart shape, a crescent moon shape, an isosceles triangle, etc., in addition to the shapes illustrated inFigure 3 and Figure 4 . Of course, the contours of the cross sections may be designed as other arbitrary shapes that satisfy the above condition regarding symmetry. - Thereby, the position at which the outer
peripheral surface 221 and the outerperipheral surface 32 become coplanar due to fitting is uniquely determined. It is desirable for thecosmetic material container 1 to have one or fewer lines L of linear symmetry (having zero lines L of linear symmetry means that a shape is asymmetrical in all directions). The reason why the number of lines L of linear symmetry is set to only one is due to preference as well as aesthetics. - However, the cosmetic material container of the present invention includes those having cross sectional shapes with two lines L of linear symmetry, such as rectangles and ellipses, those having cross sectional shapes with three lines L of linear symmetry, such as an equilateral triangle, those having cross sectional shapes with four lines L of linear symmetry, such as a square, and those having cross sectional shapes with an infinite number of lines L of linear symmetry, such as a circle.
- As illustrated in
Figure 3 , twomain body magnets 23 are mounted on the steppedsurface 222 at a predetermined angular interval other than 180 degrees along a circumferential direction having its center on the rotational axis AX. As illustrated inFigure 4 , twolid member magnets 34 are mounted on theend surface 33 at positions at the same predetermined angular interval along the circumferential direction having its center on the rotational axis AZ that cause themain body magnets 23 to face thelid member magnets 34 at a fitting position. - The two
main body magnets 23 and the twolid member magnets 34 have opposite magnetic poles facing each other at the fitting positions such that they will be magnetically attached. Themain body magnets 23 and thelid member magnets 34 maintain themain body 2 and thelid member 3 in the fitted position by magnetically attaching to each other. A combination of themain magnet 23 and thelid member 34 at a position at which opposite magnetic poles face each other is a set of magnets. In the example illustrated in the drawings, the magnetic poles of the twomain body magnets 23 are both N, and the magnetic poles of the twolid member magnets 34 are both S. Themain body 2 and thelid member 3 both have magnets with the same magnetic poles facing (exposed at) the surface. However, the magnetic poles may not be the same, and may be opposite poles. That is, one of the twomain body magnets 23 may have an N pole exposed at the abutment surface while the othermain body magnet 23 may have an S pole exposed at the abutment surface, and the one of the twolid member magnets 34 that faces themain body magnet 23 with the exposed N pole may have an S pole exposed at the abutment surface while the otherlid member magnet 34 that faces themain body magnet 23 with the exposed S pole may have an N pole exposed at the abutment surface. In this case, however, there is a disadvantage that the polarities of magnets must be changed when embedding the magnets according to the position thereof during assembly. Therefore, it is desirable for the magnets to be embedded with the same orientation as in the embodiment illustrated in the drawings. - The number of the sets of magnets is not limited to two, and it is necessary for at least one or more sets to be provided. However, in the case that only one set is provided, there is a possibility that the magnetic force that leak from the
cosmetic material container 1 will become locally strong. Therefore, it is desirable for at least two sets of magnets to be provided, so as to distribute the magnetic force that leaks. - In addition, the positions at which the
main body magnets 23 and thelid member magnets 34 are mounted are not limited to the steppedsurface 222 and theend surface 33. For example, themain body magnets 23 may be mounted on an outerperipheral surface 212 of thecolumnar portion 21, and thelid member magnets 34 may be mounted on an innerperipheral surface 35 of thelid member 3. - As illustrated in
Figure 3 and Figure 4 , themain body magnets 23 and thelid member magnets 34 are substantially circular in shape, but the shape of the magnets is not particularly limited. The magnets may be rectangular, ring shaped, etc. Themain body magnets 23 and thelid member magnets 34 are mounted at positions which are linearly symmetrical with respect to the line L of linear symmetry, but the positions at which the magnets are mounted are not particularly limited. The magnets may be provided at any position as long as opposite magnetic poles face each other in the fitted state. - If a plurality of lines L of linear symmetry exist for the contours of the outer peripheral surfaces of the
main body 2 and thelid member 3, a plurality of fitting positions at which the outerperipheral surface 221 and the outerperipheral surface 32 become coplanar will exist. In the case that all of the plurality of fitting positons are allowed, the positions at which themain body magnets 23 and thelid member magnets 34 are mounted may be positions at which opposite magnetic poles face each other in different fitting positions. - However, in the case that a logo, a mark, or the like is printed across the outer
peripheral surface 221 and the outerperipheral surface 32, and the printed contents can be visually discriminated at only a specific fitting position from among a plurality of fitting positions, for example, it is desirable for themain body magnets 23 and thelid member magnets 34 to be mounted such that opposite poles face each other only at the specific fitting position. - As illustrated in
Figure 3 , all of themain body magnets 23 are mounted such that N poles face theend surface 33 during fitting operations. As illustrated inFigure 4 , all of thelid member magnets 34 are mounted such that S poles face the steppedsurface 222 during fitting operations. The magnets may be mounted with poles opposite those of the present embodiment, that is, such that the S poles of all of themain body magnets 23 face theend surface 33 and the N poles of all of thelid member magnets 34 face the steppedsurface 222 during fitting operations. - In the case that a plurality of sets of magnets are provided, steps during manufacture can be reduced and costs can be decreased, by mounting the magnets such that the directions of the magnetic poles are aligned compared to mounting the magnets such that S poles and N poles alternate, as described previously.
- It is desirable for magnets that leak 500 gauss or less of magnetic force as measured by a known method that employs a known magnetic force sensor in the fitted state to be employed as the
main body magnets 23 and thelid member magnets 34, in order to prevent adverse influence from being imparted onto objects which are influenced by magnetic force, such as cards and memories when thecosmetic material container 1 is placed in bags or pockets. As methods realizing leaked magnetic force of 500 gauss or less other than employing weak magnets, the widths of the steppedsurface 222 and theend surface 33 may be increased to increase the distance from the magnets to the outer peripheral surface of thecosmetic material container 1, or the magnets may be distributed, even if strong magnets are employed. - As illustrated in
Figure 2 , the steppedsurface 222 includes two protrudingportions 223 which are formed on the steppedsurface 222. In addition, theend surface 33 includes two smoothly recessedportions 331 which are formed in theend surface 33. The protrudingportions 223 and the recessedportions 331 engage each other at the fitting position. -
Figures 5A through 5D are diagrams that illustrate the transition between fitting and separation of the protrudingportions 223 and the recessedportions 331. As illustrated inFigures 5A through 5D , the protrudingportions 223 have curved surfaces which are ridged with respect to the steppedsurface 222 other than the protrudingportions 223. The recessedportions 331 have curved surfaces which are recessed with respect to theend surface 33 other than the recessedportions 331. The curved surfaces of the protrudingportions 223 arefollower surfaces 224, and the curved surfaces of the recessedportions 331 are cam surfaces 332. - When the stepped
surface 222 and theend surface 33 approach each other, the cam surfaces 332 and the follower surfaces 224 contact each other (refer toFigure 5A ). The force of magnetic attraction between themain body magnets 23 and thelid member magnets 34 increases, and the cam surfaces 332 slide smoothly along the follower surfaces 224 (refer toFigure 5B ). - The
main body 2 and thelid member 3 relatively move in a direction to approach each other along the rotational axis AX while rotating relative to each other, by the cam mechanism formed by the combination of the cam surfaces 332 and the follower surfaces 224, as well as the operation of the set of magnets. - When the cam surfaces 332 and the follower surfaces 224 slide until the positions thereof match, the protruding
portions 223 and the recessedportions 331 are caused to approach each other by the force of magnetic attraction between the sets of magnets, and engage each other (refer toFigure 5C ). At this time, the sensation felt by fingers that rotate thelid member 3 is a feeling not of assisting rotation of thelid member 3, but of thelid member 3 being automatically drawn into the fitted position beyond the force of rotation. Themain body magnets 23 and thelid member magnets 34 become magnetically attached and thelid member 3 is positioned at a desired fitting position with respect to themain body 2 in this manner. The set of magnets maintain the fitted state. - When the
lid member 3 is relatively rotated with respect to themain body 2 about the rotational axis AX in order to separate thelid member 3 from themain body 2, the follower surfaces 224 slide along the cam surfaces 332 against the magnetic force (refer toFigure 5D ). The force that relatively rotates the lid member 20 about the rotational axis AX is converted to a force that separates themain body 2 and the lid member in the direction of the rotational axis AX by the operation of the cam mechanism described above. The follower surfaces 224 ride up on the cam surfaces 332, and themain body 2 and thelid member 3 are separated from each other. - The sensation felt by fingers that rotate the
lid member 3 at this time is a feeling that requires a force to rotate thelid member 3 against the magnetic force, and a feeling of an urging force that urges thelid member 3 to return to the fitting position by the magnetic force if the fingers are released. When themain body 2 and thelid member 3 move in the direction to separate from each other along the rotational axis X, the fitting is released, and thelid member 3 can be easily removed from themain body 2. - The cam mechanism described above is not limited to a combination of the protruding
portions 223 of themain body 2 and the recessedportions 331 of thelid member 3. Conversely, theend surface 33 of theline member 3 may have protrudingportions 333, and the steppedsurface 222 may have recessedportions 225. Curved surfaces of the protrudingportions 333 may be follower surfaces 334 and curved surfaces of the recessedportions 225 may be cam surfaces 226. - In addition, the follower surfaces 224 and the cam surfaces 332 are not limited to curved surfaces. As illustrated in
Figure 7 , the follower surfaces 224 may be surfaces which are inclined with respect to the steppedsurface 222 other than the protrudingportions 223, and the cam surfaces 332 may be surfaces which are inclined with respect to theend surface 33 other than the recessedportions 331. Note that use of inclined surfaces may also be applied to the follower surfaces 334 and the cam surfaces 226 (refer toFigure 6 ) as well. In this case, the respective surfaces will not be smooth as a whole. However, if the inclined surface of the recessedportion 331, which is formed in theend surface 33, adjacent to theend surface 33 is a gradual inclined surface, the follower surfaces 334 will follow and be easily guided into the recessedportions 331, and therefore smooth movement will be secured. - The shapes of the follower surfaces 224 and the cam surfaces 332 are not particularly limited. Any shapes may be adopted, as long as at least portions thereof complement each other substantially without gaps when the shapes engage each other. The same applies to the follower surfaces 334 and the cam surfaces 226 (refer to
Figure 6 ) as well. - One protruding
portion 223 and one recessedportion 331 may be provided, as illustrated inFigure 8 . In addition, the sizes of the two protrudingportions 223 and the two recessedportions 331 may largely differ, as illustrated inFigure 9 . In addition, four protrudingportions 223 and four recessedportions 331 may be provided, that is, a plurality of pairs of protruding portions and recessed portions may be provided, as illustrated inFigure 10 . The same applies to the protrudingportions 333 and the recessed portions 225 (refer toFigure 6 ) as well. - As illustrated in
Figure 11 , the present invention may be applied to acosmetic material container 6 constituted by a cylindricalmain body 4 and alid member 5 which fits onto themain body 4 in a rotatable manner about a rotational axis B. Protruding portions or recessed portions may be formed on a steppedsurface 41 of themain body 4, and recessed portions or protruding portions may be formed on anend surface 51 of the lid member. -
Figure 12 is a table that shows the results of various comparative measurements which were conducted on a cosmetic material container (E) of the present invention and other cosmetic material containers (A through D) of the type that maintain fitted states by sets of magnets. - The items of measurement are: a force (N) necessary to remove the lid members from the main bodies by pulling the lid members in the height direction without rotation; a force necessary to remove the lid members by pulling the lid members while rotating the lid members (units are Newton: N); and magnetic force that leaks in a fitted state (units are gauss: G).
- The cosmetic material containers A through C are not equipped with cam mechanisms constituted by protruding portions and recessed portions, and have configurations that maintain fitting only by magnets. The cosmetic material container A is that in which a set of ring shaped magnets are mounted, the cosmetic material container B is that in which two sets of columnar magnets are mounted, and the cosmetic material container C is that in which four sets of columnar magnets are mounted.
- The cosmetic material container D is that in which four sets of columnar magnets are mounted, and further has a positioning structure constituted by protruding portions and recessed portions. This positioning structure is a simple engagement between protrusions and recesses, and if rotation of the lid member is attempted, the protruding portions and the recessed portions do not slide with each other, but rather suppress relative rotating motion of the lid member with respect to the main body in the fitted state.
- As shown in
Figure 12 , it is possible to employ a set of magnets having a comparatively weak magnetic force in the cosmetic material container of the present invention. Thereby, it is possible to remove the lid member in thecosmetic material container 1 with a weaker force than the cosmetic material containers A through D, both in cases in which the lid member is simply pulled, and cases in which the lid member is pulled while being rotated. - As described above, according to the present embodiment, the cam mechanism formed by the cam surfaces 332 (recessed portions) and the follower surfaces (protruding portions) 224 cause the
main body 2 and thelid member 3 to approach each other or separate from each other in response to rotation of themain body 2 with respect to thelid member 3 in the axial direction of the rotational axis AX. Therefore, smooth fitting and removal can be realized. In addition, fitting operations while receiving magnetic force and removal against the magnetic force impart a favorable sense of use, a sense of richness, and a sense of class to users. - The cosmetic material container of the present invention may be applied to containers that house a cosmetic material for the eyebrows and eyes, such as eyeliner, mascara, eye shadow, and an eyebrow pencil/liner. The cosmetic material container of the present invention may also be applied to containers that house a liquid or a semiliquid cosmetic material as an external preparation for skin.
- In the above description, the follower surfaces 224 and the cam surfaces 332 provided on the abutment surfaces 222 and 33 of the
main body 2 and thelid member 3 are provided at an interval (180 degrees, for example) along an arc having the rotational axis AX at its center. However, the cam surface (step) may be a surface that rises throughout the entirety of a 360 degree angular range. Such an embodiment is illustrated inFigure 13 . -
Figure 13 illustrates a third embodiment of the present invention. A cosmetic container of the third embodiment is constituted by amain body 12 and alid member 13 which are coaxial with the rotational axis AX, and a pushtype discharge unit 12B that discharges a cosmetic material is fixed on abase end portion 12A of the main body. - The
main body 12 and thelid member 13 are of different shapes of which the cross sectional shapes perpendicular to the rotational axis AX are not circular but symmetrical with respect to one axis. The position at which the lid member is fitted onto the main body is clearly discernable from the outer shapes thereof. Astep 14 which is the same shape as anupper surface 12C of thebase end portion 12A and is smaller than theupper surface 12C is formed on theupper surface 12C. Thedischarge unit 12B is fixed on thestep 14. Thestep 14 has a deformed triangularupper surface 14B which is surrounded by aninclined surface 14A which is the side surface of thestep 14. - The
lid member 13 is equipped with anabutment surface 13A that abuts theupper surface 12C of thebase end portion 12A of the main body when fitted thereon, arecess 13B for accommodating thestep 14 of themain body 12, and ahousing hole 13C having a circular cross section for accommodating thedischarge unit 12B. The inner surface of therecess 13B is formed to accommodate thestep 14 substantially along the outer surface of thestep 14. Although not illustrated in the drawing, magnets that attract each other are embedded in the abutment surfaces 12C and 13A of themain body 12 and thelid member 13, or in the outer surface of thestep 14 and the inner surface of therecess 13B. - When the cosmetic material container of the third embodiment is opened and closed, if the
lid member 13 is rotated with respect to themain body 12 in a fitted state, thelid member 13 rides up on thestep 14 of themain body 12 to separate from themain body 12. When fitting thelid member 13 onto themain body 12, if thelid member 13 is fitted onto themain body 12 according to the outer shapes thereof, thelid member 13 is positioned along the inclined surface of thestep 14, and simultaneously attracted into the fitting position by magnetic force. In this case, 14A functions as a cam surface. - The present invention is not particularly limited to the embodiments described above, and may be modified as appropriate as long as such modifications do not stray from the spirit of the present invention.
