Description

The present invention relates to a cosmetics feeding container.

There is known a cosmetics feeding container in which the cosmetics contained in the tip cylinder are infested from the tip of the tip cylinder (see Patent Document 1). The cosmetics feeding container described in Patent Document 1 includes a tip cylinder, a substrate rotatably connected to the tip cylinder, a core chuck member inserted into the substrate and fixed to a rod-shaped cosmetic, and a surface of the core chuck member. It is provided with a spiral member screwed into the protrusion provided in the above and a cap for covering the tip cylinder.

When the tip cylinder and the substrate are rotated, the core chuck member advances while rotating in synchronization with the tip cylinder. A bend stopper is provided at the rear portion of the core chuck member, and the advance of the core chuck member is regulated by the upper end surface of the bend stopper abutting on the rear end surface of the spiral member.

Japanese Patent Application Laid-Open No. 2003-61744

However, in the invention described in Patent Document 1, when assembling the cosmetics feeding container, the bend stopper is bent inward to allow the spiral member to pass through the core chuck member, and then the protrusion of the core chuck member is formed into the spiral groove of the spiral member. Need to be screwed into. Therefore, if the bend stopper does not bend when the core chuck member passes through the spiral member, the protrusion cannot be screwed into the spiral groove, and the assembly of the cosmetics feeding container cannot be completed. Problems arise.

Further, even if the bend stopper is bent and can pass through the spiral portion, the assembly of the cosmetics feeding container may be completed with the bend stopper still bent after passing. In this case, when the cosmetics feeding container is used, the core chuck member that holds the cosmetics comes out of the cosmetics feeding container without the upper end surface of the bend stopper and the rear end surface of the spiral member coming into contact with each other. As a result, there arises a problem that the cosmetics feeding container cannot be used even though the cosmetics are sufficiently left.

Therefore, in the cosmetics feeding container described in Patent Document 1, it is necessary to complete the assembly of the cosmetics feeding container, confirm the operation of feeding and carrying back, and then fill the cosmetics container. It takes time and effort to manufacture. As a result, the manufacturing cost of the cosmetic container increases.

The present invention has been made in view of the above problems, and an object of the present invention is to reduce the manufacturing cost of a cosmetics feeding container.

The cosmetics feeding container according to the present invention includes a container body having a tip accommodating hole for accommodating cosmetics, a support member that supports the cosmetics in the container body and whose rotation is restricted by the container body, and a container body. The rear end is provided with a drive body provided so as to be rotatable relative to the container body, and a feeding mechanism for advancing and retreating cosmetics by the relative rotation between the container body and the driving body. A female screw is formed and a female screw member that rotates synchronously with the container body and a male screw screwed to the female screw of the female screw member are formed on the outer circumference so as to be rotatable synchronously with the drive body, and the relative rotation between the container body and the drive body. The support member is provided at the support portion arranged in the tip accommodating hole to support the cosmetics, the rod shaft portion extending from the support portion, and the end portion of the rod shaft portion. It has a first engaging portion that engages with the push rod and an engaging protrusion provided on the outer peripheral surface of the rod shaft portion, and the push rod has a second engaging portion that engages with the first engaging portion of the support member. It has a portion and a defining portion that regulates the advancing limit of the push rod by abutting on the female screw member, and the support member and the push rod can be relatively rotated by the first engaging portion and the second engaging portion. Connected, the container body is provided with a sliding hole communicating with the tip accommodating hole and having a diameter smaller than that of the tip accommodating hole , and a groove portion is provided along the axial direction on the inner peripheral surface of the sliding hole. By engaging the groove and the engaging protrusion, the rotation of the support member is restricted by the container body, and the relative rotation between the container body and the drive body causes the first engagement portion of the support member and the second engagement of the push rod. It is characterized in that it advances and retreats in the sliding hole in a state where it is engaged with the joint portion.

According to the present invention, a member that advances and retreats due to relative rotation between the container body and the drive body is composed of a support member that supports cosmetics and a push rod that defines a forward limit. Therefore, in the manufacturing process of the cosmetics feeding container, it is not necessary to pass the ruled portion that defines the advancing limit through the female screw member. For this reason, it is not necessary to complete the assembly of the cosmetics feeding container, confirm the operation of feeding and feeding, and then fill the cosmetics. As a result, the manufacturing cost of the cosmetics feeding container can be reduced.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<First Embodiment>
The cosmetics feeding container 1 according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 10. As shown in FIGS. 1 and 2, in the cosmetics feeding container 1, the feeding mechanism 8 works by the relative rotation between the container main body 10 and the driving body 30, and the push rod 40 and the support member 20 move forward and backward to move the container main body. The cosmetics 3 filled in the 10 are infested. The cosmetics delivery container 1 is a disposable product that is discarded when the cosmetics 3 are used up.

For convenience of explanation, the tip side of the container body 10 in which the cosmetics 3 appear is the front side of the cosmetics delivery container 1, and the bottom 37 side of the drive body 30 is the rear side of the cosmetics delivery container 1. Specify the front-back direction. Further, the direction in which the push rod 40 constituting the feeding mechanism 8 moves, that is, the direction parallel to the central axis of the container body 10 is defined as the axial direction, and the direction orthogonal to the axial direction is defined as the radial direction.

An outline of the overall configuration of the cosmetics feeding container 1 will be described with reference to FIGS. 1 and 2. The cosmetics feeding container 1 has a container body 10 in which the cosmetics 3 are housed, a support member 20 for supporting the cosmetics 3 in the container body 10, and a rear end portion of the container body 10 with respect to the container body 10. The drive body 30 provided coaxially and relatively rotatable, the feeding mechanism 8 for advancing and retreating the cosmetics 3 by the relative rotation between the container body 10 and the drive body 30, and the front end opening 11a of the container body 10 are closed for makeup. A cap 2 (see FIG. 1) for protecting the charge 3 is provided.

The feeding mechanism 8 has a push rod 40 in which a female screw member 50 having a female screw 53 (see FIG. 7) formed on the inner circumference and a male screw 41a (see FIG. 8) screwed into the female screw 53 of the female screw member 50 are formed on the outer periphery thereof. And have.

With reference to FIGS. 3 to 8, each component constituting the cosmetics feeding container 1 will be described in detail.

As shown in FIG. 3, the container body 10 is formed in a substantially cylindrical shape, and is rotatably connected to a tip cylinder portion 11 having a tip accommodating hole 17a for accommodating the cosmetics 3 and a drive body 30. The portion 15 and the hakama portion 13 provided between the tip cylinder portion 11 and the cylinder portion 15 are integrally formed of a single member. The container body 10 may be integrally formed by resin molding, or a plurality of resin members and metal members may be integrally formed by an adhesive.

The tubular body portion 15 has a larger outer diameter than the tip tubular portion 11 and the hakama portion 13, and a step portion 13c is formed between the tubular body portion 15 and the hakama portion 13. A rib 13a and a fitting convex portion 13b are provided on the outer periphery of the hakama portion 13. The step portion 13c, the rib 13a, and the fitting convex portion 13b are used for attaching the cap 2 to the container body 10.

As shown in FIG. 4, the cap 2 is formed in a bottomed cylindrical shape with one end opened. As shown in FIG. 1, the cap 2 is attached to the container body 10 and closes the front end opening 11a of the container body 10. As shown in FIG. 4, the cap 2 has a knurl 2a that engages with the rib 13a (see FIG. 3) of the container body 10 and a fitting convex portion 13b (FIG. 3) of the container body 10 on the inner circumference of the opening end thereof. An annular fitting recess 2b that fits into (see 3) is provided.

As shown in FIGS. 3 and 4, when the cap 2 is attached to the container body 10, the rib 13a of the hakama portion 13 engages with the knurl 2a of the cap 2 and locks the cap 2 in the circumferential direction. .. When the cap 2 is attached to the container body 10, the fitting convex portion 13b of the hakama portion 13 fits with the fitting concave portion 2b of the cap 2 and locks the cap 2 in the axial direction. When the cap 2 is attached to the container body 10, the step portion 13c contacts the opening edge of the rear end of the cap 2 and defines the position of the cap 2 in the axial direction.

The cap 2 is formed to have substantially the same diameter as the outer diameter of the tubular body portion 15 of the container body 10. As a result, when the cap 2 is attached to the container body 10, the outer peripheral surface of the container body 10 and the outer peripheral surface of the cap 2 become substantially flush with each other (see FIG. 1).

As shown in FIG. 3, the container body 10 has a through hole 17 that penetrates the container body 10 in the axial direction so as to communicate the front end opening 11a on the distal end side and the rear end opening 15a on the proximal end side. As shown in the figure, the through holes 17 are, in order from the tip side (front end side) to the base end side (rear end side) of the container body 10, the tip accommodating holes 17a, the sliding holes 17b, the base end holes 17c, and the like. It has a mounting hole 17i. The tip accommodating hole 17a, the sliding hole 17b, the base end hole 17c, and the mounting hole 17i are openings having concentric circular cross sections, respectively.

The support member 20 (see FIG. 5) is accommodated in the tip accommodating hole 17a, the sliding hole 17b, and the proximal end hole 17c. As shown in FIGS. 1 and 2, the support member 20 that supports the cosmetics 3 moves axially in the through hole 17 of the container body 10 as the push rod 40 advances and retreats.

As shown in FIG. 5, the support member 20 is provided at the support cylinder 22 that supports the cosmetics 3, the rod shaft portion 25 extending in the axial direction from the support cylinder 22, and the rear end portion of the rod shaft portion 25. It has an engaging portion 27 and the like. As shown in FIG. 1, when the cosmetics feeding container 1 is in an unused state, the support cylinder 22 and the cosmetics 3 are arranged in the tip accommodating hole 17a, and the rod shaft portion 25 is arranged in the sliding hole 17b. The engaging portion 27 provided at the rear end portion of the rod shaft portion 25 is arranged in the base end hole 17c.

As shown in FIG. 5, the support cylinder 22 is formed in a bottomed cylindrical shape, and the cosmetic 3 is supported from the rear side by the bottom portion 24. The rod shaft portion 25 is formed in a cylindrical shape concentric with the support cylinder 22, and is coupled to the bottom portion 24 of the support cylinder 22. The engaging portion 27 is a cylindrical portion extending in the axial direction from the rod shaft portion 25, and a bend piece 27d is provided on the side surface thereof. The outer diameter DT of the support cylinder 22 is larger than the outer diameter DR1 of the rod shaft portion 25 (DT> DR1). An opening communicating with the inside of the rod shaft portion 25 is formed in the bottom portion 24 of the support cylinder 22.

As described above, the support member 20 of the present embodiment has a support cylinder 22, a rod shaft portion 25, and an engaging portion 27 so as to communicate the front end opening 21a on the distal end side and the rear end opening 21b on the proximal end side. A through hole 21 penetrating in the direction is provided. As a result, the cosmetic 3 can be filled from either the front end opening 21a or the rear end opening 21b. A detailed description of the filling method of the cosmetic 3 will be described later.

The cosmetic 3 is fixed to the inner surface of the support cylinder 22 and the rod shaft portion 25, and the outer surface of the cosmetic 3 is maintained in a state of being supported by the support member 20. The rear end surface of the support member 20 (rear end surface of the engaging portion 27) is a contact surface 26 with which the flange portion 47d (see FIGS. 2C and 8) of the push rod 40 abuts. As will be described later, the contact surface 26 is pushed by the push rod 40, and the support member 20 advances together with the push rod 40, so that the cosmetic 3 supported by the support member 20 is paid out from the front end opening 11a of the container body 10 ( See FIG. 2 (a)).

On the outer peripheral surface of the support cylinder 22, a plurality of protrusions 23 protruding outward in the radial direction are provided at equal intervals in the circumferential direction. The protrusion amount of each protrusion 23 is set so that each protrusion 23 abuts on the inner peripheral surface of the tip accommodating hole 17a. That is, the support cylinder 22 slides in the tip accommodating hole 17a in the axial direction in a state where the protrusion 23 is in contact with the inner peripheral surface of the tip accommodating hole 17a.

The rod shaft portion 25 is provided with a rib 25a extending in the axial direction as an engaging protrusion on the outer peripheral surface thereof. The rib 25a is fitted into the valley portion (see FIG. 3) of the uneven portion 18 of the sliding hole 17b, which will be described later (see FIG. 2B). That is, as shown in FIGS. 1 and 2, the rod shaft portion 25 is arranged in the sliding hole 17b so as not to rotate relative to the container main body 10. This makes it impossible for the support member 20 to move in the circumferential direction with respect to the container body 10, that is, relative rotation.

As shown in FIG. 5, a slit 27a is formed on the side surface of the cylindrical engaging portion 27 in a substantially U shape, and the inner portion of the slit 27a is formed as a bend piece 27d. The bend piece 27d has a fixed end on the rear end side (rear end side of the engaging portion 27) of the support member 20, and a free end on the tip. A protrusion 27b is formed on the outer peripheral surface of the tip of the bend piece 27d so as to project outward in the radial direction.

The outer peripheral surface of the protrusion 27b is located radially outward of the outer peripheral surface of the rod shaft portion 25. Here, the maximum radial dimension of the engaging portion 27 in the radial direction is defined as the opening / closing portion external dimension DB1 (see FIG. 5A). In the present embodiment, the opening / closing portion external dimension DB1 is located at a position opposite to the protrusion 27b of the bend piece 27d and the protrusion 27b in the engaging portion 27, that is, 180 ° from the protrusion 27b around the central axis of the support member 20. It is a dimension between the outer peripheral surface of the engaging portion 27 at the displaced position. The opening / closing portion external dimension DB1 is larger than the outer diameter DR1 of the rod shaft portion 25 and smaller than the outer diameter DT of the support cylinder 22 (DR1 <DB1 <DT).

The bend piece 27d is an elastic member that elastically deforms between a closed state that is closed inward in the radial direction (see FIG. 2) and an open state that is open outward in the radial direction (see FIGS. 1 and 5). The bend piece 27d functions as an opening / closing portion that can be opened / closed by elastic deformation, and is a portion connected to the tip of the push rod 40. When a pressing force is applied from the outside in the radial direction, the bend piece 27d is elastically deformed so that its tip moves toward the central axis of the support member 20.

Next, the configuration of each part of the through hole 17 in which the support member 20 is housed will be described in detail. As shown in FIG. 3, the tip accommodating hole 17a is a hole accommodating the support cylinder 22, and its inner diameter DL1 is slightly larger than the outer diameter DT (see FIG. 5) of the support cylinder 22 (DL1> DT). Therefore, a slight gap is formed between the inner peripheral surface of the tip accommodating hole 17a and the outer peripheral surface of the support cylinder 22. As described above, the protrusion 23 provided on the outer peripheral surface of the support cylinder 22 abuts on the inner peripheral surface of the tip accommodating hole 17a.

As shown in FIG. 3, the inner diameter DL1 of the tip accommodating hole 17a is larger than the inner diameter DS1 of the sliding hole 17b provided so as to communicate with the tip accommodating hole 17a (DL1> DS1). Therefore, a step portion 17d is formed between the tip accommodating hole 17a and the sliding hole 17b. The outer diameter DT of the support cylinder 22 (see FIG. 5) is larger than the inner diameter DS1 of the sliding hole 17b (DS1 <DT). Therefore, the stepped portion 17d, which is the opening edge portion of the sliding hole 17b, abuts on the bottom portion 24 of the support cylinder 22 to regulate the movement of the support cylinder 22 to the base end side of the container body 10. Functions as. That is, the retreat limit of the support member 20 is the position of the support member 20 when the bottom portion 24 of the support cylinder 22 is in contact with the step portion 17d.

The base end hole 17c is provided so as to communicate with the sliding hole 17b. The base end hole 17c is a hole for opening the bend piece 27d, and the sliding hole 17b is a hole for closing the bend piece 27d.

The inner diameter DL2a of the proximal cavity portion 17g of the proximal hole 17c is larger than the inner diameter DS1 of the sliding hole 17b (DL2a> DS1). A tapered hole 17f whose diameter gradually decreases from the proximal cavity portion 17g toward the sliding hole 17b is provided between the proximal cavity portion 17g and the sliding hole 17b. The tapered surface of the tapered hole 17f is continuous with the inner peripheral surface of the sliding hole 17b at the front end and continuous with the inner peripheral surface of the proximal cavity portion 17g at the rear end.

The inner diameter DL2a of the proximal cavity portion 17g of the proximal end hole 17c is larger than the opening / closing portion external dimension DB1 (see FIG. 5) (DL2a> DB1). When the bend piece 27d is located in the proximal hole 17c (see FIG. 1), the bend piece 27d is in an open state that is open outward in the radial direction as compared with the closed state. Therefore, when the head 47a of the push rod 40 is inserted from the rear end opening 21b of the support member 20 when assembling the cosmetics feeding container 1, the bend piece 27d does not hinder the forward movement of the head 47a, and the head The portion 47a can be arranged in front of the tip of the bend piece 27d (see FIG. 1).

An uneven portion (flat knurl) 18 extending in the axial direction is formed on the inner peripheral surface of the sliding hole 17b by knurling. The uneven portion 18 has a wave-shaped cross section in which peaks and valleys are alternately arranged in the circumferential direction, and is continuously formed over the entire sliding hole 17b.

The inner diameter DS1 of the sliding hole 17b is slightly larger than the outer diameter DR1 of the rod shaft portion 25 of the support member 20 (DS1> DR1). In the present embodiment, the inner diameter DS1 of the sliding hole 17b refers to the diameter of a virtual circular cross section connecting the tops of a plurality of peaks of the uneven portion 18 in the sliding hole 17b. The rib 25a of the rod shaft portion 25 described above is fitted into the valley portion (groove portion) of the uneven portion 18 (see FIG. 2B). Therefore, the rod shaft portion 25 slides in the sliding hole 17b in the axial direction.

The inner diameter DS1 of the sliding hole 17b is smaller than the opening / closing external dimension DB1 (see FIG. 5) (DS1 <DB1). Therefore, as shown in FIG. 2, when the bend piece 27d is located in the sliding hole 17b, the bend 27d has the protrusion 27b inward by the top of the mountain portion of the uneven portion 18 in the sliding hole 17b. When pressed, it elastically deforms (deflects) and becomes a closed state that is closed inward in the radial direction. Therefore, when the cosmetics feeding container 1 is used, the connecting portion 99 between the tip of the push rod 40 and the base end of the support member 20 can be moved forward and backward in a state of being firmly connected (a state in which the connection cannot be released) (a state in which the connection cannot be released). See Figure 2).

As shown in FIG. 5, the dimension LR1 from the rear end surface of the bottom 24 of the support cylinder 22 to the tip of the bend piece 27d, that is, the axial length of the rod shaft portion 25 is the retreat limit of the support member 20 (FIG. 1). The stroke (movement amount) from the forward limit (see FIG. 2) to the forward limit (see FIG. 2) is set to a length of SP1 or more. As a result, as shown in FIG. 2, when the support member 20 is located at the forward limit, the engaging portion 27 can be arranged in the sliding hole 17b, so that the tip of the push rod 40 and the support member 20 can be arranged. It is possible to maintain the connected state of the connecting portion 99 with the base end of the above.

Next, a mounting hole 17i provided behind the base end hole 17c, and a drive body 30 and a female screw member 50 mounted in the mounting hole 17i will be described. As shown in FIG. 3, an uneven portion (flatfish knurl) 17h extending in the axial direction is formed on the inner peripheral surface of the mounting hole 17i by knurling. The uneven portion 17h has a wavy cross section in which peaks and valleys are alternately arranged in the circumferential direction, and is formed in the front portion of the mounting hole 17i. An annular fitting recess 17j is provided on the inner circumference in the vicinity of the rear end opening 15a of the mounting hole 17i. The uneven portion 17h is used for attaching the female screw member 50, and the fitting recess 17j is used for attaching the drive body 30.

The inner diameter DL3 of the mounting hole 17i is larger than the inner diameter DL2a of the proximal cavity portion 17g (DL3> DL2a). Therefore, a step portion 17e is formed between the mounting hole 17i and the proximal cavity portion 17g.

As shown in FIG. 6, the drive body 30 has a circular opening 30a extending in the front-rear direction, and has a bottomed substantially cylindrical shape in which the front end is opened and the rear end is closed by the bottom 37. It is formed. The drive body 30 has an fitting portion 31 that is fitted into the mounting hole 17i of the container body 10, and a knob portion 32 that is continuously formed in the fitting portion 31 and used by the user.

The fitting portion 31 is formed in a substantially cylindrical shape. A fitting convex portion 34 that fits into the fitting concave portion 17j (see FIG. 3) of the container body 10 is formed in an annular shape on the outer periphery of the vicinity of the base end of the fitting portion 31 (near the knob portion 32). An annular O-ring groove 33 is formed on the outer periphery of the fitting portion 31 in front of the fitting convex portion 34. By attaching the O-ring 4 (see FIGS. 1 and 2) to the O-ring groove 33, it is possible to impart an appropriate resistance to the relative rotation between the container body 10 and the drive body 30, and the user feels comfortable with the operation. Can be improved.

The outer diameter of the grip portion 32 is larger than the outer diameter of the fitting portion 31. The knob portion 32 is formed to have substantially the same diameter as the outer diameter of the container body 10. As a result, when the drive body 30 is assembled to the container body 10, the outer peripheral surface of the container body 10 and the outer peripheral surface of the grip portion 32 become substantially flush with each other (see FIGS. 1 and 2).

A plurality of grooves 35 are provided on the inner peripheral surface of the opening 30a of the drive body 30. The groove 35 extends axially from the bottom portion 37 of the drive body 30 to the front end opening 39. When the rib 43a (see FIG. 8) of the large diameter portion 43 of the push rod 40, which will be described later, is fitted into the groove 35, the relative rotation between the drive body 30 and the push rod 40 becomes impossible (see FIG. 1 (c)). ). In this embodiment, four grooves 35 are provided.

As shown in FIG. 7, the female screw member 50 has a cylindrical large-diameter portion 50a and a cylindrical small-diameter portion 50b provided concentrically with the large-diameter portion 50a. Since the outer diameter of the large diameter portion 50a is larger than the outer diameter of the small diameter portion 50b, a step portion 54 is formed between the large diameter portion 50a and the small diameter portion 50b. The large diameter portion 50a is inserted into the mounting hole 17i (see FIG. 3) of the container body 10, and the small diameter portion 50b is inserted into the opening 30a (see FIG. 6) of the drive body 30.

As shown in FIG. 1, in the female screw member 50, the front end surface 51a of the female screw member 50 abuts on the step portion 17e of the container body 10, and the step portion 54 of the female screw member 50 abuts on the front end surface of the drive body 30. In this state, it is housed in the mounting hole 17i of the container body 10. That is, the female screw member 50 is sandwiched between the step portion 17e of the container body 10 and the front end surface of the drive body 30, and the movement in the axial direction is restricted.

As shown in FIG. 7, the large-diameter portion 50a of the female screw member 50 is provided with a rib 52 extending in the axial direction as an engaging protrusion on the outer peripheral surface thereof. The rib 52 is fitted into the valley portion (groove portion) of the uneven portion 17h (see FIG. 3) of the mounting hole 17i. This makes it impossible for the female screw member 50 to move in the circumferential direction with respect to the container body 10, that is, relative rotation (see FIG. 1 (b)). Therefore, when the user rotates the container body 10 relative to the drive body 30, the female screw member 50 rotates synchronously with the container body 10.

The female screw member 50 is provided with a through hole penetrating in the axial direction, and the female screw 53 is formed on the inner peripheral surface of the through hole. The female screw 53 is formed on the same lead as the lead of the male screw 41a (see FIG. 8) of the push rod 40.

As shown in FIG. 8, the push rod 40 is formed in a substantially columnar shape. The push rod 40 is housed inside the container body 10 and the drive body 30 (see FIG. 1). The push rod 40 includes a rod shaft 41 provided coaxially with the container body 10 and the drive body 30, an engaging portion 47 provided at the tip of the rod shaft 41, and a large diameter portion 43 provided at the base end of the rod shaft 41. It has a cavity 44 recessed in the axial direction from the large diameter portion 43.

On the outer circumference of the rod shaft 41, a male screw 41a to be screwed into the female screw 53 (see FIG. 7) of the female screw member 50 is formed. The cosmetic 3 (see FIGS. 1 and 2) contained in the tip accommodating hole 17a of the container body 10 is extruded little by little and used. Therefore, the pitch of the male screw 41a is set to a pitch at which the push rod 40 can be finely moved.

The large diameter portion 43 is formed in a disk shape, and its outer diameter is larger than the outer diameter of the rod shaft 41. The large diameter portion 43 has a front end surface 43b that abuts on the rear end surface 51b of the female screw member 50 and a rear end surface 43c that abuts on the bottom portion 37 of the drive body 30. The large diameter portion 43 moves in the drive body 30 in the axial direction (see FIGS. 1 and 2).

A plurality of ribs 43a slidably engaged with the groove 35 of the drive body 30 (see FIG. 6C) are formed on the outer periphery of the large diameter portion 43. As described above, when the rib 43a engages with the groove 35 of the drive body 30, the relative rotation between the push rod 40 and the drive body 30 becomes impossible (see FIG. 1 (c)). Therefore, when the drive body 30 is relatively rotated with respect to the container body 10, the push rod 40 rotates synchronously with the drive body 30.

The large-diameter portion 43 provided at the base end of the push rod 40 is a defining portion that defines the forward and backward limits of the push rod 40 that advances and retreats by the feeding mechanism 8. The large-diameter portion 43 defines the retreat limit of the push rod 40 by the rear end surface 43c abutting on the bottom portion 37 of the drive body 30 (see FIG. 1). The large-diameter portion 43 defines the forward limit of the push rod 40 by the front end surface 43b abutting on the rear end surface 51b of the female screw member 50 (see FIG. 2).

The engaging portion 47 provided at the tip of the push rod 40 is connected to the engaging portion 27 (see FIG. 5) provided at the rear end of the support member 20. In the present embodiment, the connecting portion 99 is configured by the engaging portion 27 of the support member 20 and the engaging portion 47 of the push rod 40 (see FIGS. 1 and 2).

The engaging portion 47 has a cylindrical cylindrical portion 47c, a conical head 47a provided at the front end of the cylindrical portion 47c, and an annular flange portion 47d provided at the rear end of the cylindrical portion 47c. .. The outer diameter of the cylindrical portion 47c is smaller than the outer diameter of the rod shaft 41 and smaller than the outer diameter of the head 47a. Since the outer diameter of the bottom surface of the head 47a is larger than the outer diameter of the cylindrical portion 47c, the bottom surface of the head 47a is referred to as the step portion 47b.

The flange portion 47d is provided at the rear end of the columnar portion 47c so as to project radially outward from the columnar portion 47c. A recess 47p into which the bend piece 27d is fitted is formed at the tip of the push rod 40. The outer peripheral surface of the cylindrical portion 47c corresponds to the bottom surface of the recess 47p. The front surface of the step portion 47b and the flange portion 47d facing the step portion 47b corresponds to a pair of side surfaces of the recess 47p.

As shown in FIGS. 1 and 2, the bend piece 27d of the support member 20 is arranged so as to face the bottom surface of the recess 47p of the engaging portion 47 of the push rod 40 in the radial direction. As will be described later, when the push rod 40 moves forward, the flange portion 47d pushes the contact surface 26, so that the support member 20 moves forward together with the push rod 40. Further, when the push rod 40 is retracted, the step portion 47b pulls the bend piece 27d, so that the support member 20 retracts together with the push rod 40.

The procedure for assembling the cosmetics delivery container 1 will be described with reference to FIGS. 1 and 3 to 9. As shown in FIG. 9, the cosmetics feeding container 1 has a main body side assembly step for forming the main body side assembly 29, a cosmetic filling step for filling the cosmetics 3, and a drive body side for forming the drive body side assembly 59. It has an assembly step and a connecting step of connecting the main body side assembly 29 and the drive body side assembly 59.

The main body side assembly process will be described with reference to FIGS. 3, 5, and 9. In the main body side assembly step, the support member 20 is inserted into the through hole 17 from the front end opening 11a of the container main body 10 by using a jig or the like. The bend piece 27d is in the open state when it is located in the tip accommodating hole 17a, but is in the closed state when it is inserted into the sliding hole 17b.

When the support member 20 is inserted until the bottom portion 24 of the support cylinder 22 abuts on the stepped portion 17d of the through hole 17 of the container body 10, the bend piece 27d is arranged in the base end hole 17c. When the bend piece 27d is inserted into the base end hole 17c, the bend piece 27d is in an open state that is open outward in the radial direction as compared with the case where the bend piece 27d is inserted into the sliding hole 17b.

When the bottom portion 24 of the support cylinder 22 comes into contact with the stepped portion 17d of the through hole 17, the stepped portion 17d restricts the rearward movement of the support cylinder 22. Therefore, even if an external force toward the rear is applied to the support member 20, the support member 20 is prevented from falling off from the rear end opening 15a of the container body 10.

As shown in FIG. 9, a temporary cap 70 is attached to the front end of the container body 10 and arranged so that the front side of the container body 10 faces vertically downward.

When the front side of the container body 10 is turned vertically downward, the bend piece 27d of the support member 20 is caught in the tapered hole 17f. Further, a plurality of protrusions 23 (see FIG. 5) provided on the outer peripheral surface of the support cylinder 22 are pressed against the inner peripheral surface of the tip accommodating hole 17a. Therefore, when the front side of the container body 10 is directed vertically downward, the support member 20 is prevented from moving forward (vertically downward) due to its own weight.

The temporary cap 70 is formed in a bottomed cylindrical shape and has a bottom portion 71 and a tubular portion 72 rising from the outer peripheral edge of the bottom portion 71. When the temporary cap 70 is attached to the front end portion of the container body 10, the front end opening 11a is closed. The inner surface of the bottom portion 71 is formed in a planar shape parallel to the opening surface of the front end opening 11a.

As described above, the main body side assembly 29 is completed by attaching the support member 20 and the temporary cap 70 to the container main body 10, and the main body side is positioned so that the front side of the main body side assembly 29 faces vertically downward. The assembly process is complete. The main body side assembly 29 is not provided with the push rod 40 and the female screw member 50 constituting the feeding mechanism 8. Therefore, the rear end opening 21b of the support member 20 is open, and the filling nozzle 60 can be inserted from the rear end opening 21b of the support member 20 in the next cosmetic filling step.

In the cosmetic filling step, the cosmetic 3 is filled in the tip accommodating hole 17a by the following procedure. First, the filling nozzle 60 is inserted into the through hole 17 from the rear end opening 15a of the container main body 10 constituting the main body side assembly 29, and further, the filling nozzle 60 is inserted into the through hole 21 from the rear end opening 21b of the support member 20. insert.

A predetermined amount of the liquid cosmetic 3 heated and melted is poured from the opening at the tip of the filling nozzle 60. In the work of pouring the liquid cosmetics 3, the position of the tip of the filling nozzle 60 may be appropriately adjusted.

After filling a predetermined amount of the cosmetic 3, the cosmetic 3 is cooled and solidified. The cosmetic 3 becomes a stick-shaped cosmetic core by solidifying. The cosmetic 3 is fixed to the inner surface of the support cylinder 22 and the inner surface of the rod shaft portion 25. By attaching the cosmetic 3 not only to the support cylinder 22 but also to the rod shaft portion 25, the adhesive force of the cosmetic 3 to the support member 20 can be improved.

Most of the cosmetics 3 filled in the container body 10 by such a method are soft such as gel. Therefore, if the user excessively dispenses the cosmetic 3 from the front end opening 11a when using the cosmetic feeding container 1, the cosmetic core may be broken. Therefore, in the present embodiment, the pitch of the male screw 41a of the push rod 40 is set to a pitch at which the push rod 40 can be finely moved, so that when the user uses the cosmetic delivery container 1, the cosmetic 3 is dispensed from the front end opening 11a. Prevent it from passing.

As described above, a slight gap is formed between the outer peripheral surface of the support cylinder 22 and the inner peripheral surface of the tip accommodating hole 17a. Therefore, when the cosmetic 3 is filled, air can be released to the rear (vertically upward) through the gap between the support cylinder 22 and the inner peripheral surface of the tip accommodating hole 17a. As a result, the melted liquid cosmetic 3 can be smoothly poured into the tip accommodating hole 17a, and the working time can be shortened. In addition, it is possible to prevent the formation of voids (cavities) that occur when air remains inside the cosmetics.

The drive body side assembly process will be described with reference to FIGS. 6 to 9. In the drive body side assembly step, the push rod 40 is inserted into the opening portion 30a of the drive body 30 from the rear end side, and the rear end surface 43c of the large diameter portion 43 is brought into contact with the bottom portion 37 of the drive body 30. When the push rod 40 is inserted into the drive body 30, the rib 43a of the large diameter portion 43 and the groove 35 of the drive body 30 are engaged with each other.

The tip of the push rod 40 is passed through the through hole of the female thread member 50 from the rear end side of the female thread member 50, and the female thread 53 and the male thread 41a are screwed together. The female screw member 50 is rotated relative to the push rod 40 until the step portion 54 of the female screw member 50 comes into contact with the front end surface of the drive body 30. When the step portion 54 of the female screw member 50 is in contact with the front end surface of the drive body 30, as shown in FIG. 9, the engaging portion 47 of the push rod 40 protrudes forward from the through hole of the female screw member 50. ..

The O-ring 4 is attached to the O-ring groove 33 of the drive body 30. The O-ring 4 may be attached to the O-ring groove 33 before the push rod 40 is inserted inside the drive body 30, or may be attached to the O-ring groove 33 after the push rod 40 is inserted inside the drive body 30. May be good.

As described above, by attaching the push rod 40, the female screw member 50, and the O-ring 4 to the drive body 30, the drive body side assembly 59 is completed.

The connecting process will be described with reference to FIGS. 1 and 9. In the connecting step, the front end portion of the drive body side assembly 59 is inserted into the mounting hole 17i from the rear end opening 15a of the container main body 10 constituting the main body side assembly 29, and the front end surface 51a of the female screw member 50 is inserted into the container main body 10. It is brought into contact with the step portion 17e. When the front portion of the drive body side assembly 59 is inserted into the mounting hole 17i, the rib 52 (see FIG. 7) of the female screw member 50 and the valley portion (groove portion) of the uneven portion 17h are engaged with each other.

In the connecting step, the engaging portion 47 of the push rod 40, the female screw member 50, and the tip of the drive body 30 are passed through the rear end opening 15a of the container body 10 constituting the main body side assembly 29, and the fitting portion 31 of the drive body 30 is inserted into the container. It is inserted into the mounting hole 17i of the main body 10. At this time, the engaging portion 47 of the push rod 40 is inserted into the through hole 21 from the rear end opening 21b of the engaging portion 27 of the support member 20. Since the bend piece 27d is in the open state in the base end hole 17c, the engaging portion 47 of the push rod 40 can be smoothly inserted into the through hole 21 of the support member 20.

The front end surface 51a of the female screw member 50 is brought into contact with the step portion 17e of the container body 10, and the fitting convex portion 34 of the drive body 30 and the fitting recess 17j of the container body 10 are fitted. As a result, as shown in FIG. 1, the main body side assembly 29 and the drive body side assembly 59 are connected.

Finally, the temporary cap 70 is removed from the front end of the container body 10 and the cap 2 is attached to the container body 10 to complete the cosmetics feeding container 1 (see FIG. 1).

Since the bottom portion 71 of the temporary cap 70 is formed in a plane parallel to the opening surface of the front end opening 11a, the tip surface of the cosmetic 3 after the temporary cap 70 is removed from the container body 10 is a flat surface with a clean finish. And the appearance can be improved. If characters and patterns are formed on the bottom 71 of the temporary cap 70 by concave portions and convex portions, convex and concave characters and patterns corresponding to the shape of the bottom 71 can be formed on the tip surface of the cosmetics 3. can.

As described above, an example of the manufacturing method of the cosmetics feeding container 1 has been described, but the manufacturing procedure of the cosmetics feeding container 1 is not limited to the above-mentioned procedure. For example, as shown in FIG. 10, the cosmetic filling step may be performed after the connecting step of connecting the main body side assembly 29 and the drive body side assembly 59 is completed.

In this case, the filling nozzle 60 is inserted into the through hole 17 from the front end opening 11a of the container body 10, and a predetermined amount of the liquid cosmetic 3 is poured. At this time, since the head 47a of the push rod 40 is arranged in the through hole 21 of the support member 20 and closes the rear end side of the through hole 21, the liquid cosmetic 3 is introduced from the rear end opening 21b of the support member 20. It is prevented from flowing down. As described above, since the push rod 40 can be used as a closing member for the through hole 21, it is not necessary to provide a dedicated closing member.

After filling a predetermined amount of the cosmetic 3, the cosmetic 3 is cooled and solidified, and the cap 2 is attached to the container body 10 to complete the cosmetic feeding container 1 (see FIG. 1).

Next, with reference to FIGS. 1 and 2, the operation of the cosmetics delivery container 1 when the cosmetics delivery container 1 is used will be described. FIG. 1 shows a state before the start of use of the cosmetics delivery container 1, and shows the cosmetics delivery container 1 in which the push rod 40 is located at the retreat limit. FIG. 2 shows a cosmetics delivery container 1 in which the push rod 40 is located at the forward limit.

As shown in FIG. 1, in a state where the push rod 40 is located at the retreat limit, a connecting portion 99 between the tip of the push rod 40 and the base end of the support member 20 is arranged at the initial connection portion. As described above, the retreat limit of the push rod 40 is the position of the push rod 40 when the large diameter portion 43 of the push rod 40 abuts on the bottom portion 37 of the drive body 30 and the retreat of the push rod 40 is restricted. ..

When the connecting portion 99 is located at the initial connection portion, the tip of the bend piece 27d is arranged in the base end hole 17c in the through hole 17, and the bend piece 27d is in an open state. That is, in the state before the start of use (see FIG. 1), the tip of the bend piece 27d of the support member 20 does not enter the recess 47p of the engaging portion 47 of the push rod 40.

The user removes the cap 2 from the container body 10 so that the cosmetic 3 can be delivered. Next, when the user rotates the drive body 30 in one direction (forward rotation) with respect to the container body 10, the push rod 40 rotates in one direction with respect to the female screw member 50 together with the drive body 30. Since the female screw 53 and the male screw 41a are screwed together, when the push rod 40 rotates in one direction with respect to the female screw member 50, the push rod 40 advances with respect to the container body 10 and the drive body 30.

As the push rod 40 advances, the contact surface 26 of the support member 20 is pushed by the flange portion 47d of the push rod 40. As a result, the support member 20 advances together with the push rod 40 in the through hole 17 of the container body 10, and the cosmetic 3 contained in the container body 10 is pushed out from the front end opening 11a. Since the rib 25a of the support member 20 is fitted in the valley portion (groove portion) of the uneven portion 18 of the through hole 17, the support member 20 advances with respect to the container body 10 without rotating. That is, the push rod 40 pushes the support member 20 forward while rotating with respect to the support member 20.

When the push rod 40 advances and the support member 20 is pushed by the push rod 40, the bend piece 27d comes into contact with the tapered surface of the tapered hole 17f and gradually bends inward. Further, when the bend piece 27d is inserted into the sliding hole 17b of the through hole 17, the bend piece 27d bends by coming into contact with the inner peripheral surface of the sliding hole 17b, resulting in a closed state. That is, the pressing force inward from the inner peripheral surface of the sliding hole 17b acts on the tip end side of the bend piece 27d, so that the tip end side of the bend piece 27d is elastically deformed inward with the base end side as a fulcrum and is in a closed state. become. As a result, the bend piece 27d is fitted into the concave portion 47p of the engaging portion 47 as a convex portion protruding inward.

As a result, the bend piece 27d provided at the base end of the support member 20 and the engaging portion 47 provided at the tip end of the push rod 40 are firmly connected in the sliding hole 17b. The user pays out the cosmetics 3 by a predetermined amount and uses the cosmetics 3. When the use of the cosmetic 3 is finished, the user repeats the delivered cosmetic 3. The method of carrying back the cosmetics 3 is as follows.

When the user rotates the drive body 30 to the other side (reverse rotation) with respect to the container body 10, the push rod 40 rotates to the other side with respect to the female screw member 50 together with the drive body 30. When the push rod 40 rotates to the other side with respect to the female screw member 50, the push rod 40 retracts with respect to the container body 10. As the push rod 40 retracts, the tip of the bend piece 27d is pulled by the stepped portion 47b of the engaging portion 47 of the push rod 40. As a result, the support member 20 retracts together with the push rod 40 in the through hole 17 of the container body 10, and the cosmetic 3 protruding outward from the container body 10 is returned into the through hole 17. The user attaches the cap 2 to the container body 10 and stores the cosmetics feeding container 1.

In this way, due to the relative rotation between the container body 10 and the drive body 30, the engaging portion 27 of the support member 20 and the engaging portion 47 of the push rod 40 move back and forth in the sliding hole 17b in an engaged state.

As the cosmetics feeding container 1 continues to be used and the cosmetics 3 decreases, the cosmetics feeding container 1 reaches the usage limit state. Hereinafter, the usage limit state will be described. When the user continuously rotates the drive body 30 in the forward direction to advance the push rod 40, as shown in FIG. 2, the large diameter portion 43 of the push rod 40 comes into contact with the rear end surface 51b of the female screw member 50, and the front of the push rod 40. Movement to is restricted. When the push rod 40 is located at the forward limit, the amount of payout (protrusion amount) of the cosmetic 3 is maximized. As described above, the advance limit of the push rod 40 is the position of the push rod 40 when the large diameter portion 43 of the push rod 40 abuts on the female screw member 50 and the advance of the push rod 40 is restricted. When the cosmetics 3 are reduced to such an extent that the cosmetics 3 cannot be used while the push rod 40 is located at the forward limit, the cosmetics delivery container 1 is in a use limit state and is discarded.

In the present embodiment, the large-diameter portion 43 as a defining portion that defines the forward limit abuts on the rear end surface of the female screw member 50 over the entire circumference (range of 360 °). As a result, even if a strong load due to the rotational force is applied in the forward limit, the large diameter portion 43 does not deform or break due to contact with the female screw member 50, and the forward limit is surely defined. It is possible to prevent the charge feeding container 1 from being damaged.

As described above, the length LR1 from the support cylinder 22 to the bend piece 27d is set to a length equal to or greater than the stroke SP1 from the retreat limit to the forward limit of the support member 20. Therefore, as shown in FIG. 2, when the push rod 40 is located at the forward limit, the connecting portion 99 between the tip of the push rod 40 and the base end of the support member 20 is arranged in the sliding hole 17b. That is, since the tip (free end) of the bend piece 27d is arranged in the sliding hole 17b and is restrained by the inner peripheral surface of the sliding hole 17b, the connection of the connecting portion 99 is prevented from being disconnected in a strong connection state. Is maintained.

When the push rod 40 is located in the forward limit, the support member 20 is also located in the forward limit. When the push rod 40 and the support member 20 are located at the forward limit, the cosmetics 3 cannot be delivered, so that the user can be made to recognize that the cosmetics delivery container 1 has reached the usage limit state.

In the first embodiment, the flange portion 47d of the push rod 40 is the support member 20 from the state before the start of use (see FIG. 1) to the use limit state (see FIG. 2) in which the push rod 40 is extended to the maximum. It abuts on the contact surface 26 (see FIG. 5). Therefore, the stroke (movement amount) from the backward limit to the forward limit of the push rod 40 is equal to the stroke (movement amount) from the backward limit to the forward limit of the support member 20.

According to the first embodiment described above, the following effects are obtained.

(1) In the present embodiment, the member that advances and retreats by the relative rotation of the container body 10 and the drive body 30 is composed of a support member 20 that supports the cosmetics 3 and a push rod 40 that defines an advance limit and a retract limit. Will be done. Therefore, in the manufacturing process of the cosmetics feeding container 1, it is not necessary to pass the large diameter portion 43 that defines the advancing limit to the female screw member 50. Therefore, it is not necessary to complete the assembly of the cosmetics feeding container 1, confirm the operation of feeding and carrying back, and then fill the cosmetics 3. As a result, the manufacturing cost of the cosmetics feeding container 1 can be reduced.

(2) In the cosmetics feeding container 1 according to the present embodiment, the support member 20 is provided with an engaging portion (first engaging portion) 27 for connecting to the push rod 40, and the push rod 40 is provided with the support member 20. An engaging portion (second engaging portion) 47 for connecting is provided. Therefore, the cosmetic 3 can be moved back and forth from the front end opening 11a by moving back and forth in the sliding hole 17b with the support member 20 and the push rod 40 engaged.

(3) The outer diameter DT of the support cylinder (support portion) 22 that supports the cosmetics 3 is larger than the inner diameter DS1 of the sliding hole 17b. As a result, during the assembly work, the bottom portion 24 of the support cylinder 22 comes into contact with the stepped portion 17d, and the support member 20 is prevented from falling off from the rear end opening 15a of the container body 10.

(4) The rod shaft portion 25 of the support member 20 is provided with a rib 25a that fits into the valley portion (groove portion) of the uneven portion 18 of the sliding hole 17b, and the rod shaft portion 25 rotates relative to the container body 10. It is impossible to be arranged in the sliding hole 17b. Here, when the rib 25a is not provided, the rotational force due to the friction of the push rod 40 is transmitted to the support member 20, and the support member 20 and the cosmetic 3 rotate with respect to the container body 10. Since the cosmetic 3 moves back and forth while twisting in the container body 10, there is a risk that the cosmetic 3 will break. On the other hand, in the present embodiment, the rib 25a and the uneven portion 18 prevent the cosmetic 3 from rotating relative to the container body 10, so that the core of the cosmetic 3 can be prevented from breaking.

(5) The support member 20 is provided with a through hole 21 that penetrates the support cylinder 22 and the rod shaft portion 25 in the axial direction. As a result, the filling nozzle 60 can be inserted from either the rear end opening 21b or the front end opening 21a of the support member 20, and the filling operation of the cosmetics 3 can be performed. According to the present embodiment, since the filling method of the cosmetics 3 can be selected according to the manufacturing equipment, the manufacturing schedule, and the like, the degree of freedom in assembling the cosmetics feeding container 1 can be improved.

(6) When filling the cosmetic 3 from the rear end opening 21b side of the support member 20 (see FIG. 9), in the present embodiment, the filling nozzle 60 is inserted from the rear end opening 15a of the container body 10 and the cosmetic 3 is filled. By connecting the main body side assembly 29 and the drive body side assembly 59, the rear end opening 15a of the container main body 10 and the rear end opening 21b of the support member 20 are closed by the drive body side assembly 59. Therefore, as in the case where the opening at the rear end of the container is closed by a closing member such as a seal or a breechblock after filling the cosmetic from the opening at the rear end of the container (for example, the technique described in Japanese Patent Application Laid-Open No. 2003-61744). It is not necessary to provide a dedicated closing member. In addition, the labor required for the work can be saved. Further, the appearance can be improved as compared with the case where a dedicated closing member is provided.

(7) The outer diameters of the cap 2, the tubular body portion 15, and the knob portion 32 forming the outer shape of the cosmetics feeding container 1 are formed to the same extent. Therefore, the outer peripheral surfaces of the cap 2, the tubular body portion 15, and the knob portion 32 are substantially flush with each other, so that the cosmetics feeding container 1 having a small diameter can be obtained.

<Second Embodiment>
Hereinafter, the cosmetics delivery container 101 according to the second embodiment of the present invention will be described. In the figure, the same or corresponding parts as those in the first embodiment are designated by the same reference numbers, and the differences will be mainly described. As shown in FIGS. 11 and 12, the main difference from the cosmetics feeding container 1 according to the first embodiment is the configuration of the support member 120, the container body 110, and the push rod 140, and in particular, the support member 120. The mode of the connecting portion 199 of the push rod 140 is different. Since the support member 120 according to the second embodiment is not provided with a through hole that penetrates the support cylinder 122 and the rod shaft portion 125 in the axial direction, the cosmetic 103 is introduced from the front end opening 11a of the container body 110. Is limited to filling (see FIG. 16). Hereinafter, the configuration of the cosmetics delivery container 101 according to the second embodiment will be described in detail while appropriately comparing with the configuration of the cosmetics delivery container 1 according to the first embodiment.

First, the through hole 117 of the container body 110 according to the second embodiment will be described. As shown in FIG. 13, at the front end portion of the sliding hole 117b, a tapered hole 117k whose diameter gradually increases toward the tip accommodating hole 17a is provided. Since the maximum inner diameter of the tapered hole 117k is smaller than the inner diameter DL1 of the tip accommodating hole 17a, a step portion 117d is formed between the tip accommodating hole 17a and the tapered hole 117k. The tapered hole 117k is provided when a plurality of bend pieces 127d (see FIG. 14) provided at the rear end portion of the rod shaft portion 125 are inserted into the sliding hole 117b when the support member 120 is attached to the container body 110. The bend piece 127d is gradually deformed inward. That is, by providing the tapered hole 117k, the insertability of the bend piece 127d into the sliding hole 117b can be improved.

In the first embodiment, the uneven portion 18 is formed only in the sliding hole 17b (see FIG. 3). On the other hand, in the second embodiment, the uneven portion (flatfish knurl) 118 is continuously formed in each of the sliding hole 117b, the tapered hole 117f of the proximal hole 117c, and the proximal cavity portion 117g.

The inner diameter DL2b of the proximal cavity portion 117g of the proximal hole 117c is larger than the inner diameter DS2 of the sliding hole 117b (DL2b> DS2). In the present embodiment, the inner diameter DS2 of the sliding hole 117b refers to the diameter of a virtual circular cross section connecting the tops of a plurality of peaks of the uneven portion 118 in the sliding hole 117b. Further, the inner diameter DL2b of the proximal cavity portion 117g of the proximal end hole 117c refers to the diameter of a virtual circular cross section connecting the tops of a plurality of mountain portions of the concave-convex portion 118 in the proximal end cavity portion 117g. The rib 127a of the engaging portion 127, which will be described later, is fitted into the valley portion (groove portion) of the uneven portion 118 (see FIG. 12B). The rib 125a of the rod shaft portion 125, which will be described later, is also fitted into the valley portion (groove portion) of the uneven portion 118 provided in the sliding hole 117b (see FIG. 11B).

The inner diameter DL3 of the mounting hole 17i is larger than the inner diameter DL2b of the proximal cavity portion 117g (DL3> DL2b). Therefore, a step portion 117e is formed between the mounting hole 17i and the proximal cavity portion 117g.

Next, the support member 120 according to the second embodiment will be described. As shown in FIG. 14, the support member 120 is provided at the support cylinder (support portion) 122, the rod shaft portion 125 extending in the axial direction from the support cylinder 122, and the rear end portion of the rod shaft portion 125. It has a joint portion (first engaging portion) 127 and.

The rod shaft portion 125 is a shaft-shaped member that connects the support cylinder 122 and the engaging portion 127. Here, when the rod shaft portion 125 is formed in a columnar shape, the resin may shrink during molding of the support member 120 and “sink” may occur. "Sink" is more likely to occur as the thickness of the member is thicker. Therefore, the rod shaft portion 125 according to the second embodiment is formed in a cross-sectional shape. The rod shaft portion 125 has four ridge portions 125b provided around the central axis of the support member 120 at intervals of 90 degrees.

Each ridge portion 125b extends axially from the support cylinder 122 to the engaging portion 127. The space between the ridges 125b adjacent to each other in the circumferential direction is a recess formed as a meat steal 125c. By forming the meat stealing 125c on the rod shaft portion 125 in this way, the central portion of the rod shaft portion 125 can be made small in diameter (thin), so that the occurrence of “sink” during resin molding can be prevented. Can be done.

Two of the four ridges 125b are provided with ribs 125a having the same functions as the ribs 25a described in the first embodiment.

The bottom portion 24 of the support cylinder 122 is coupled to the rod shaft portion 125. The outer diameter DT of the support cylinder 122 is larger than the outer diameter DR2 of the rod shaft portion 125 (DT> DR2).

The support cylinder 122 according to the second embodiment is a thin-film tubular member whose wall thickness is thinner than the wall thickness of the support cylinder 22 according to the first embodiment. The wall thickness of the cylindrical portion of the support cylinder 122 is formed to be thinner than the wall thickness of the bottom portion 24 of the support cylinder 122. As a result, as shown in FIG. 11, in the cosmetic 103 supported by the support cylinder 122, the step in contact with the front end surface of the support cylinder 122 can be substantially eliminated, so that the cosmetic 103 can be made difficult to break. ..

The support cylinder 122 is provided with a plurality of slits 122a. The slit 122a extends axially from the front end surface of the support cylinder 122. Therefore, in the cosmetic filling step, the liquid cosmetic 103 also flows into the slit 122a, and the cooled and solidified cosmetic 103 is filled in the slit 122a. Therefore, it is possible to effectively prevent the cosmetics 103 from coming out of the support cylinder 122.

The engaging portion 127 is coupled to the rear end of the rod shaft portion 125 and has a plurality of bend pieces 127d extending substantially in the axial direction from the rear end side of the rod shaft portion 125. More specifically, the plurality of bend pieces 127d extend so as to gradually open outward from the proximal end side toward the distal end side, that is, to move away from the central axis of the support member 120 toward the distal end side.

Each bend piece 127d has a bend piece main body 127c extending from the rear end of the rod shaft portion 125, a rib 127a protruding outward from the outer peripheral surface of the tip end portion of the bend piece main body 127c, and a bend piece main body 127c. It is provided with a protrusion 127b that projects inward from the inner peripheral surface of the tip portion.

In the present embodiment, four bend pieces 127d are provided at intervals of 90 degrees in the circumferential direction about the central axis of the support member 120. The bend piece 127d has a fixed end whose base end is coupled to the rod shaft portion 125, and whose tip is a free end. The pair of bend pieces 127d facing each other are inclined with respect to the central axis of the support member 120 so that the dimension between the pair of bend piece main bodies 127c increases toward the tip.

The outer peripheral surface of the plurality of bend pieces 127d is located radially outward of the outer peripheral surface of the rod shaft portion 125. In the second embodiment, the opening / closing portion external dimension DB2 is the dimension between the tips of the pair of bend piece main bodies 127c facing each other, that is, the maximum external dimension between the pair of bend piece main bodies 127c (FIG. 14A). reference). The opening / closing portion external dimension DB2 is larger than the outer diameter DR2 of the rod shaft portion 125 and smaller than the outer diameter DT of the support cylinder 122 (DR2 <DB2 <DT).

The plurality of bend pieces 127d are elastic members that elastically deform between an open state that opens radially outward (see FIGS. 11 and 14) and a closed state that closes radially inward (see FIG. 12). be. The plurality of bend pieces 127d function as an opening / closing portion that can be opened / closed by elastic deformation, and is a portion connected to an engaging portion (second engaging portion) 147 (see FIG. 15) provided at the tip of the push rod 140. .. When a pressing force is applied from the outside in the radial direction, the bend piece 127d is elastically deformed so that its tip moves toward the central axis of the support member 120.

As shown in FIG. 13, the inner diameter DS2 of the sliding hole 117b of the container body 110 is smaller than the opening / closing portion external dimension DB2 (see FIG. 14A) (DS2 <DB2). Further, the inner diameter DL2b (see FIG. 13C) of the proximal cavity portion 117g of the proximal end hole 117c is larger than the opening / closing portion external dimension DB2 (DL2b> DB2).

Therefore, when the engaging portion 127 is located in the sliding hole 117b, the outer peripheral surface of the bend piece main body portion 127c is inside the plurality of bend pieces 127d by the top of the mountain portion of the uneven portion 118 in the sliding hole 117b. When pressed against, it elastically deforms and becomes a closed state that is closed inward in the radial direction (see FIG. 12). On the other hand, when the engaging portion 127 is located in the proximal hole 117c, the plurality of bend pieces 127d are in an open state that is radially outwardly open as compared with the closed state (see FIG. 11).

As shown in FIG. 14, the dimension LR2 from the rear end surface of the bottom 24 of the support cylinder 122 to the base end of the bend piece 127d, that is, the axial length of the rod shaft portion 125 is the retreat limit of the support member 120 (FIG. 14). The length from the stroke (movement amount) SP2 or more from the forward limit (see FIG. 12) to the advance limit (see FIG. 12) is set. As a result, as shown in FIG. 12, when the support member 120 is located at the forward limit, the engaging portion 127 can be arranged in the sliding hole 117b, so that the tip of the push rod 140 and the support member 120 can be arranged. It is possible to maintain the connected state of the connecting portion 199 with the base end of the above.

As shown in FIG. 14, a recess 127p into which the head portion 147a (see FIG. 15) of the engaging portion 147 at the tip of the push rod 140, which will be described later, is fitted is formed at the base end of the support member 120. The bottom surface of the recess 127p is a contact surface 126 with which the top surface 142 (see FIG. 15) of the push rod 40 abuts, and the inner peripheral surface of the plurality of bend pieces 127d corresponds to the side surface of the recess 127p.

The rib 125a provided on the rod shaft portion 125 and the rib 127a provided on the bend piece 127d engage with the valley portion (groove portion) of the uneven portion 118 of the through hole 117, whereby the circumference of the support member 120 with respect to the container body 10 is peripheral. Directional movement, that is, relative rotation, becomes impossible (see FIGS. 11 (b) and 12 (b)). As a result, when the push rod 140 advances and retreats while rotating with respect to the support member 120, when the rotational force due to friction is transmitted from the push rod 140 to the support member 120, the support member 120 rotates relative to each other in the container body 10. , Ribs 125a, 127a can be prevented by engaging with the valley portion (groove portion) of the uneven portion 118.

As shown in FIG. 15, the engaging portion 147 provided at the tip of the push rod 140 is connected to the engaging portion 127 (see FIG. 14) provided at the rear end of the support member 120. The engaging portion 147 has a cylindrical portion 147c having a cylindrical shape and a conical head portion 147a provided at the front end of the cylindrical portion 147c. The outer diameter of the cylindrical portion 147c is smaller than the outer diameter of the rod shaft 141 and smaller than the outer diameter of the head 147a. Since the outer diameter of the bottom surface of the head portion 147a is larger than the outer diameter of the cylindrical portion 147c, the bottom surface of the head portion 147a is referred to as a step portion 147b.

In the first embodiment, the front end surface of the flange portion 47d (see FIG. 8) of the engaging portion 47 is a contact surface that comes into contact with the support member 20 when the push rod 40 advances. On the other hand, in the second embodiment, the top surface 142 of the head portion 147a of the engaging portion 147 is a contact surface that comes into contact with the support member 120 when the push rod 140 is advanced.

The rod shaft 141 has a small male screw protrusion 141b formed continuously from the male screw 41a on the outer periphery thereof. The male screw small protrusion 141b is formed to have a smaller outer diameter than the male screw 41a. Therefore, when the push rod 140 is located at the forward limit and a force for further feeding is applied, the male screw small protrusion 141b repeats screw release and screw return with the female screw 53. By repeating the unscrew release and the screw return, a tick and an intermittent resistance are generated, so that the user can be notified that the push rod 140 is located at the forward limit and the use is finished. As a result, damage to the members due to excessive force applied to the cosmetics feeding container 101 is prevented.

Next, a method of assembling the cosmetics feeding container 101 according to the second embodiment will be described. In the cosmetics feeding container 1 according to the first embodiment, since the support member 20 is provided with a through hole 21 penetrating in the axial direction, the cosmetics 3 can be filled from either the front side or the rear side of the container body 10. (See FIGS. 9 and 10). On the other hand, the cosmetics feeding container 101 according to the second embodiment does not have a configuration corresponding to the through hole 21 described in the first embodiment. Therefore, as shown in FIG. 16, in the method for manufacturing the cosmetics feeding container 101 according to the second embodiment, the cosmetics 103 can be filled only from the front side of the container main body 110.

The cosmetic filling step may be performed after connecting the main body side assembly 129 and the drive body side assembly 159 (see FIG. 16), or connecting the main body side assembly 129 and the drive body side assembly 159. You may go before letting.

Next, with reference to FIGS. 11 and 12, the operation of the cosmetics delivery container 101 when the cosmetics delivery container 101 according to the second embodiment is used will be described. As shown in FIG. 11, in the state where the push rod 140 is located in the retracting limit, the connecting portion 199 between the tip of the push rod 140 and the base end of the support member 120 is arranged at the initial connection portion.

When the connecting portion 199 is located at the initial connection portion, the tip of the bend piece 127d is arranged in the base end hole 117c in the through hole 117, and the bend piece 127d is in an open state. That is, in the state before the start of use (see FIG. 11), the engaging portion 147 of the push rod 140 is not fitted in the recess 127p of the support member 120.

The user removes the cap 2 from the container body 110 so that the cosmetic 103 can be delivered. Next, when the user rotates the drive body 30 in one direction (forward rotation) with respect to the container body 110, the push rod 140 is advanced by the feeding mechanism 108.

As the push rod 140 advances, the contact surface 126 of the support member 120 is pushed by the top surface 142 of the push rod 140. As a result, the support member 120 advances together with the push rod 140 in the through hole 117 of the container body 110, and the cosmetic 103 contained in the container body 110 is pushed out from the front end opening 11a. Since the ribs 125a and 127a of the support member 120 are fitted into the valleys (grooves) of the uneven portion 118 of the through hole 117, the support member 120 advances without rotating with respect to the container body 110. That is, the push rod 140 pushes the support member 120 forward while rotating with respect to the support member 120.

When the push rod 140 advances and the support member 120 is pushed by the push rod 140, the bend piece 127d comes into contact with the tapered surface of the tapered hole 117f and gradually bends inward. Further, when the bend piece 127d is inserted into the sliding hole 117b of the through hole 117, the bend piece 127d bends by coming into contact with the inner peripheral surface of the sliding hole 117b, resulting in a closed state. That is, the pressing force inward from the inner peripheral surface of the sliding hole 117b acts on the tip end side of the bend piece 127d, so that the tip end side of the bend piece 127d is elastically deformed inward with the proximal end side as a fulcrum and is in a closed state. become. As a result, the head 147a of the push rod 140 is fitted into the concave portion 127p of the engaging portion 127 as a convex portion protruding forward, and the engaging portion 147 of the push rod 140 is sandwiched by the plurality of bend pieces 127d.

As a result, the engaging portion 127 provided at the base end of the support member 120 and the engaging portion 147 provided at the tip of the push rod 140 are firmly connected in the sliding hole 117b.

In this state, when the user rotates the drive body 30 to the other side (reverse rotation) with respect to the container body 110, the push rod 140 rotates to the other side with respect to the female screw member 50 together with the drive body 30. When the push rod 140 rotates to the other side with respect to the female screw member 50, the push rod 140 retracts with respect to the container body 110. As the push rod 140 retracts, the protrusion 127b of the bend piece 127d is pulled by the step portion 147b of the engaging portion 147 of the push rod 140. As a result, the support member 120 retracts together with the push rod 140 in the through hole 117 of the container body 110, and the cosmetic 103 protruding outward from the container body 110 is returned into the through hole 117.

As described above, the connecting portion 199 between the base end of the support member 120 and the tip of the push rod 140 advances and retreats the sliding hole 117b with the stroke of the push rod 140 while maintaining a strong connection state in which the disconnection is prevented. do.

In the second embodiment, the top surface 142 of the push rod 140 is the support member 120 from the state before the start of use (see FIG. 11) to the use limit state (see FIG. 12) in which the push rod 140 is extended to the maximum. It abuts on the contact surface 126 (see FIG. 14). Therefore, the stroke (movement amount) from the retreat limit to the forward limit of the push rod 140 is equal to the stroke (movement amount) from the retreat limit to the forward limit of the support member 120.

According to such a second embodiment, the same effects as those described in (1) to (4) and (7) described in the first embodiment are obtained.

<Third Embodiment>
Hereinafter, the cosmetics delivery container 201 according to the third embodiment of the present invention will be described. In the figure, the same or corresponding parts as those in the first embodiment are designated by the same reference numbers, and the differences will be mainly described. As shown in FIGS. 17 and 18, the main difference from the cosmetics feeding container 1 according to the first embodiment is the configuration of the container body 210 and the push rod 240. Hereinafter, the configuration of the cosmetics delivery container 201 according to the third embodiment will be described in detail while appropriately comparing with the configuration of the cosmetics delivery container 1 according to the first embodiment.

The cosmetics delivery container 201 is assembled in the same procedure as in the first embodiment (see FIG. 18). As shown in FIG. 17, the flange portion 247d of the push rod 240 according to the third embodiment is thicker than the collar portion 47d (see FIG. 2) of the push rod 40 according to the first embodiment. long). Therefore, in the connecting step of connecting the main body side assembly 229 and the drive body side assembly 259, the amount (length) of the support member 20 being pushed forward by the flange portion 247d is larger than that of the first embodiment. Therefore, the support member 20 is pushed by the flange portion 247d of the push rod 240, the cosmetic 203 is pushed out from the front end opening 211a, and the connecting portion 99 also moves into the sliding hole 17b.

Therefore, in the third embodiment, when the connecting step is completed and the connecting portion 99 is located at the initial connection portion, the tip of the bend piece 27d is arranged in the sliding hole 17b, and the bend piece 27d is in the closed state. It has become. That is, in the state before the start of use, the tip of the bend piece 27d of the support member 20 has entered the recess 47p of the engaging portion 47 of the push rod 240.

At this time, the push rod 240 is located in the retracting limit, but the support member 20 is not located in the retracting limit. That is, in the third embodiment, a gap is formed between the bottom portion 24 of the support cylinder 22 of the support member 20 and the step portion 17d of the container main body 210 in the state before the start of use.

As described above, in the third embodiment, the support member 20 can be advanced together with the cosmetic 203 with the push rod 240 positioned at the retracting limit when the cosmetic delivery container 201 is assembled. On the other hand, in the cosmetics feeding container (1) described in Patent Document 1, the core chuck member (30) to which the cosmetics are fixed when the tip cylinder (10) and the substrate (20) are rotated. However, due to the screwing function with the spiral member (40), the structure advances while rotating in synchronization with the tip cylinder (10). That is, in the cosmetics feeding container (1) described in Patent Document 1, the core chuck member (30), which is a single member, has a function of supporting the cosmetics and a function of advancing and retreating by screwing. With the core chuck member (30) positioned at the retracting limit, it is not possible to advance the portion that supports the cosmetic when assembling the container.

As shown in FIG. 17A, the inner peripheral surface of the tip accommodating hole 217a of the container body 210 has a tapered surface so that the inner diameter of the tip accommodating hole 217a gradually increases from the step portion 17d toward the front end opening 211a. Has been done. As shown in FIG. 18, the cosmetic 203 is formed in a state where the bend piece 27d of the support member 20 is located in the tapered hole 17f, as in the first embodiment. Therefore, when the support member 20 is pushed by the flange portion 247d of the push rod 240 in the connecting step and the connecting portion 99 is located at the initial connection portion, as shown in FIG. A slight gap S is formed between each outer peripheral surface of the material 203 and the inner peripheral surface (tapered surface) of the tip accommodating hole 217a.

The gap S becomes larger as the support member 20 and the cosmetic 203 move toward the front end opening 211a. Therefore, when the cosmetic 203 moves forward and backward, the sliding resistance between the support cylinder 22 of the support member 20 and the cosmetic 203 and the tip accommodating hole 217a can be reduced, and the cosmetic 203 is prevented from breaking. can.

Further, in the first embodiment, an example in which the bottom portion 71 of the temporary cap 70 is formed in a plane parallel to the opening surface of the front end opening 11a has been described (see FIG. 9). On the other hand, in the third embodiment, as shown in FIG. 18, a protruding portion 271 is provided at the bottom of the temporary cap 270 so as to enter the tip accommodating hole 217a. The contact surface of the protrusion 271 that comes into contact with the cosmetic 203 is formed in a curved shape so that the central axis side of the cosmetic 203 bulges forward with respect to the outer peripheral side. As a result, after the temporary cap 270 is removed from the container body 210, the tip surface of the cosmetic 203 can be made into a curved surface with a clean finish, and when the cosmetic 203 is extruded from the front end opening 211a in the connecting process. Appearance can be improved.

According to such a third embodiment, in addition to the same actions and effects as those described in (1) to (7) described in the first embodiment, the following actions and effects are exhibited.

(8) In the third embodiment, in the connecting step, the support member 20 is advanced while the push rod 240 is positioned at the retracting limit, so that the outer peripheral surface of the support cylinder 22 and the inner peripheral surface of the tip accommodating hole 217a are brought into contact with each other. A gap S is formed between the space and between the outer peripheral surface of the cosmetic 203 and the inner peripheral surface of the tip accommodating hole 217a. As a result, the sliding resistance at the time of advancing and retreating the cosmetic 203 can be reduced, and the cosmetic 203 can be prevented from breaking. As a result, it is possible to prevent the occurrence of a problem that the broken cosmetic 203 cannot be carried back.

The following modifications are also within the scope of the present invention, and the configurations shown in the modifications may be combined with the configurations described in the above-described embodiments, or the configurations described in the above-mentioned different embodiments may be combined, and the following differences may occur. It is also possible to combine the configurations described in the modified example.

<Modification 1>
In the first embodiment, the example in which the tip of the bend piece 27d of the support member 20 does not enter the recess 47p of the engaging portion 47 of the push rod 40 in the state before the start of use (see FIG. 1) has been described. Is not limited to this. In the state before the start of use (see FIG. 1), the tip of the bend piece 27d may enter the recess 47p. In the second embodiment, an example in which the engaging portion 147 of the push rod 140 is not fitted in the recess 127p of the support member 120 in the state before the start of use (FIG. 11) has been described, but the present invention is not limited thereto. .. In the state before the start of use (see FIG. 11), the engaging portion 147 may be fitted in the recess 127p. That is, in the initial state (state before the start of use) after assembling the cosmetics feeding container 1, 101, the push rods 40, 140 are positioned at the retracting limit, and the sliding holes 17b, due to the subsequent advancement of the push rods 40, 140, It suffices if the push rods 40, 140 and the support members 20, 120 are in an engaged state in which the push rods 40, 140 and the support members 20, 120 can move forward and backward in 117b.

<Modification 2>
In the above embodiment, an example in which liquid cosmetics 3, 103, 203 are poured into the tip accommodating holes 17a, 217a of the container bodies 10, 110, 210 and solidified has been described, but the present invention is not limited thereto.
