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.

  • 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 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.

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.

  • 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.
