Description

The present invention relates to a feeding container.

Conventionally, for example, the feeding container described in Patent Document 1 below has been known. The feeding container has a regulating cylinder having a vertical hole extending in the axial direction of the container and a spiral cylinder having a spiral hole extending in the circumferential direction and being rotatably attached to the regulating cylinder. Has a container body in which the container body is housed, a holding portion arranged inside the container body to hold the contents, and a locking protrusion that protrudes outward in the radial direction from the holding portion and enters the vertical hole and the spiral hole. A middle plate, which is restricted from rotating relative to the regulating cylinder by locking the locking protrusion to the vertical hole, is provided.
In this feeding container, when the user rotates the regulation cylinder and the spiral cylinder relative to each other, the locking protrusion is locked to the inner peripheral surface of the vertical hole, so that the inner plate rotates with the regulation cylinder. At this time, as the locking protrusion moves along the spiral hole, the entire inner plate moves back and forth in the direction of the container axis, and the contents held by the holding portion appear and disappear from the container body.

Japanese Unexamined Patent Publication No. 2013-208154

In the conventional feeding container, when an unexpected external force is applied to the contents in a state where the contents protrude from the container body in the container axial direction, the external force is transmitted to the spiral cylinder via the contents and the inner plate. .. At this time, for example, the locking protrusion abuts on the inner peripheral surface of the spiral hole and a load is applied to the contents to break the contents, or the locking protrusion unintentionally slides on the inner peripheral surface of the spiral hole. As a result, the contents may sink into the container body.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to suppress breakage and unintentional subduction of the contents, and to improve the usability of the feeding container.

In order to solve the above problems, the present invention proposes the following means.
The feeding container according to the present invention includes a regulation cylinder having a vertical hole extending in the axial direction of the container and a spiral cylinder having a spiral hole extending in the circumferential direction and rotatably mounted on the regulation cylinder. A container body that has and accommodates the contents, a holding portion that is arranged in the container body and holds the contents, and a vertical hole and a spiral hole that protrude outward in the radial direction from the holding portion. A feeding container having a locking protrusion that enters the spiral hole, and a middle plate that is restricted from rotating relative to the regulating cylinder by locking the locking protrusion in the vertical hole. The spiral cylinder is formed of an elastically deformable soft material , the spiral cylinder is attached to the regulation cylinder from the outside in the radial direction, and the spiral hole is a female screw formed on the inner peripheral surface of the spiral cylinder. It is characterized in that the thread of the female thread portion is formed by the portion and is pressed against the regulation cylinder from the outside in the radial direction .

According to the present invention, the spiral cylinder is formed of a soft material that can be elastically deformed. Therefore, when an unexpected external force is applied to the contents in a state where the contents protrude from the container body in the direction of the container axis and the external force is transmitted to the spiral cylinder through the contents and the inner plate, the spiral cylinder is moved. It can be elastically deformed. As a result, the above-mentioned external force can be absorbed by the elastic deformation of the spiral cylinder. At this time, although the contents sink into the container body, the contents can be restored and displaced by the subsequent restoration and deformation of the spiral cylinder. As a result, it is possible to suppress breakage of the contents and unintentional subduction. Further, even when the content is pressed against the portion to be coated, the spiral cylinder is elastically deformed according to the pressing force to prevent the content from being excessively increased against the portion to be coated. Can be done. From the above, the usability of the feeding container can be improved.

A plurality of the vertical holes and the locking protrusions may be arranged at equal intervals in the circumferential direction.

In this case, a plurality of vertical holes and locking protrusions are arranged at equal intervals in the circumferential direction. Therefore, when the regulation cylinder and the spiral cylinder are relatively rotated, the entire inner plate can be stably moved back and forth with respect to the container body.

The said locking projection, said external thread portion to be screwed into the female screw portion is formed, the external thread portion and the internal thread portion may be a multiple thread structure.

In this case, the male threaded portion and the female threaded portion have a multi-threaded screw structure. Therefore, for example, as compared with the case where the male threaded portion and the female threaded portion have a single thread structure, it is possible to keep the pitch and the lead angle small while securing a large lead, and the contact area between the male threaded portion and the female threaded portion. (The contact area between the locking protrusion and the inner peripheral surface of the spiral hole) can be easily increased. Therefore, in combination with the fact that a plurality of vertical holes and locking protrusions are arranged at equal intervals in the circumferential direction, an unexpected external force applied to the contents can be applied to the contents and the inner plate. It can be effectively transmitted to the spiral tube through.

The locking protrusion may be formed in a rectangular shape extending in the container axial direction in the front view thereof.

In this case, the locking protrusion is formed in a rectangular shape extending in the container axial direction in the front view thereof. Therefore, it is possible to secure the contact area between the locking protrusion and the inner peripheral surface of the vertical hole, and when the regulation cylinder and the spiral cylinder are relatively rotated, the inner plate is stabilized together with the regulation cylinder. Can be carried around.

According to the present invention, it is possible to suppress breakage and unintentional subduction of the contents and improve the usability of the feeding container.

The middle plate 14 holds the content A in a state of protruding toward the front side (one side) in the container shaft O direction, and the container shaft O is accompanied by the relative rotation of the regulation cylinder 11 and the spiral cylinder 12 in the circumferential direction. By advancing and retreating in the direction and advancing to the front side, the content A is projected from the opening (discharge hole, indentation hole) on the front side in the container body 13.

The central axes of the regulating cylinder 11, the spiral cylinder 12, and the decorative cylinder 20 are located on a common axis. Hereinafter, this common shaft is referred to as a container shaft O, the direction in which the content A protrudes from the middle plate 14 along the container shaft O is referred to as a front side, and the opposite side (the other side) is referred to as a rear side. In a plan view of the feeding container 10 from the container axis O direction, the direction orthogonal to the container axis O is referred to as the radial direction, and the direction of orbiting around the container axis O is referred to as the circumferential direction.
Examples of the content A include a rod-shaped body in which a cosmetic (lipstick, lip balm, stick eye shadow, etc.), a drug, glue, or the like is formed in a rod shape.

The regulation cylinder 11 is formed by connecting the rear base portion 15 and the front adherend portion 16 in the container shaft O direction.
The adherend portion 16 projects forward from the inner peripheral edge of the front end surface of the base portion 15, and is longer than the base portion 15 in the container axis O direction. The inner peripheral surface of the adherend portion 16 and the inner peripheral surface of the base portion 15 are flush with each other. The outer peripheral surface of the adherend portion 16 is located inside the outer peripheral surface of the base portion 15 in the radial direction, and the base portion 15 projects outward in the radial direction from the adherend portion 16.

The outer diameter of the adherend portion 16 is smaller than the outer diameter of the base portion 15. As shown in FIG. 3, the outer diameter of the rear end portion (hereinafter, referred to as “large diameter portion 16a”) connected to the base portion 15 in the adhered portion 16 is located on the front side of the adhered portion 16 with respect to the rear end portion. It is larger than the outer diameter of the portion (hereinafter referred to as "small diameter portion 16b"). The small diameter portion 16b is larger in the container axis O direction than the large diameter portion 16a.
A vertical hole 23 extending in the container axis O direction is formed in the regulation cylinder 11. As shown in FIGS. 1 to 3, the vertical hole 23 penetrates the regulation cylinder 11 in the radial direction. A plurality of vertical holes 23 are arranged at equal intervals in the circumferential direction. A pair of vertical holes 23 are arranged in the small diameter portion 16b (adhesion portion 16) so as to sandwich the container shaft O in between, and have the same shape and the same size as each other. The vertical hole 23 is provided over the entire length of the small diameter portion 16b in the container shaft O direction, and opens from the regulation cylinder 11 toward the front side.

As shown in FIG. 1, the spiral cylinder 12 is attached to the regulation cylinder 11 from the outside in the radial direction, and is outer to the regulation cylinder 11. The spiral cylinder 12 is exteriorized by being displaced forward with respect to the regulation cylinder 11, and in the illustrated example, the spiral cylinder 12 is exteriorized by the adhered portion 16 of the regulation cylinder 11. The spiral cylinder 12 has the same size as the adherend portion 16 along the container axis O direction.
As shown in FIG. 3, the spiral cylinder 12 is formed with a spiral hole 24 extending in the circumferential direction. The spiral hole 24 is formed in a groove shape on the inner peripheral surface of the spiral cylinder 12, and is not open toward the outside in the radial direction. A female screw portion 24a is formed on the inner peripheral surface of the spiral cylinder 12, and the spiral hole 24 is formed by the female screw portion 24a. The spiral hole 24 is a thread valley of the female threaded portion 24a. As shown in FIG. 1, the female screw portion 24a is formed in the spiral cylinder 12 over the entire area in the container axis O direction excluding the front end portion.

The decorative cylinder 20 is attached to the spiral cylinder 12 from the outside in the radial direction, and is exteriorized by the spiral cylinder 12. The decorative cylinder 20 is longer than the spiral cylinder 12 in the container axis O direction, and the spiral cylinder 12 is located inside the container shaft O direction of the decorative cylinder 20. The rear end portion of the decorative cylinder 20 projects to the rear side of the spiral cylinder 12, and is rotatably fitted to the base portion 15 of the regulation cylinder 11 from the outside in the radial direction. The front end portion of the decorative cylinder 20 is bent inward in the radial direction over the entire circumference thereof, and covers the adhered portion 16 of the regulation cylinder 11 and the front end portions of the spiral cylinder 12 from the front. The opening located inside the front end of the decorative cylinder 20 forms the front opening in the container body 13.

The regulation cylinder 11, the spiral cylinder 12, and the decorative cylinder 20 are made of different materials. For example, the regulation cylinder 11 and the spiral cylinder 12 are made of a synthetic resin material, and the decorative cylinder 20 is made of a metal material. Further, the spiral cylinder 12 is formed of a material that is softer and elastically deformable than the material that forms the regulation cylinder 11 and the decorative cylinder 20, respectively. The spiral cylinder 12 is formed of an elastically deformable soft material such as an elastomer. The spiral cylinder 12 is fitted (tightened) to the decorative cylinder 20 from the inside in the radial direction. As a result, the spiral cylinder 12 and the decorative cylinder 20 are restricted from rotating relative to each other.

The middle plate 14 has a holding portion 26 that is arranged in the container body 13 (inside the regulation cylinder 11) and holds the contents A, and a vertical hole 23 and a spiral hole 24 that protrude outward from the holding portion 26 in the radial direction. A locking protrusion 25 that enters the space is provided. By locking the locking protrusion 25 to the vertical hole 23, the relative rotation of the inner plate 14 and the regulation cylinder 11 is restricted. The middle plate 14 is substantially non-rotatable with respect to the regulation cylinder 11.
The holding portion 26 is slidably fitted in the regulation cylinder 11 in the container shaft O direction. The holding portion 26 is formed in a tubular shape that opens toward both sides in the container axis O direction. The content A is fitted in the holding portion 26 in a state of being arranged coaxially with the container shaft O. A plurality of locking protrusions 25 are arranged at equal intervals in the circumferential direction. A pair of locking protrusions 25 are arranged so as to sandwich the container shaft O in between, and have the same shape and the same size as each other.

As shown in FIG. 4, the locking protrusion 25 is formed in a rectangular shape extending in the container axis O direction in the front view (front view of the locking protrusion 25 viewed from the outside in the radial direction). The rectangular shape extends in the container axis O direction and the circumferential direction, and is longer in the container axis O direction than in the circumferential direction. The rectangular shape has the same size as the vertical hole 23 in the circumferential direction.
The locking protrusion 25 is formed with a male screw portion 25a that is screwed into the female screw portion 24a. The male screw portion 25a is formed on the outer surface of the locking protrusion 25 facing outward in the radial direction. The male screw portion 25a extends in a spiral shape in the circumferential direction.
The locking protrusion 25 has entered the spiral hole 24 through the vertical hole 23, and is integrally inserted into the vertical hole 23 and the spiral hole 24. In the illustrated example, the thread of the male threaded portion 25a enters the thread valley of the female threaded portion 24a from the inside in the radial direction, so that the locking protrusion 25 is arranged in the spiral hole 24.

The male threaded portion 25a and the female threaded portion 24a have a multi-threaded screw structure. As shown in FIG. 3, in the present embodiment, the male threaded portion 25a and the female threaded portion 24a have an eight-threaded screw structure. For example, when the pitch P in the male screw portion 25a and the female screw portion 24a is 1 mm, the lead L is 8 mm (8 times the pitch P), and when the regulation cylinder 11 and the spiral cylinder 12 make one relative rotation, the regulation is performed. The cylinder 11 and the spiral cylinder 12 move 8 mm in the container axis O direction.

In the present embodiment, the spiral cylinder 12 is made of a soft material that can be elastically deformed as described above. As shown in FIG. 5, the spiral cylinder 12 is made of a material that is softer and elastically deformable than the material that forms the locking protrusion 25. In the illustrated example, the holding portion 26 and the locking protrusion 25 of the inner plate 14 are integrally formed of the same material, and the spiral cylinder 12 is a material that is softer and elastically deformable than the material forming the inner plate 14. Is formed by. The middle plate 14 can be formed of, for example, a material having the same hardness as the regulation cylinder 11.

In the feeding container 10, in the initial state as shown in FIG. 1, the entire contents A are completely housed inside the container body 13. In the initial state, as shown in FIG. 5, the thread of the female screw portion 24a located at the rear end of the spiral cylinder 12 is pressed against the large diameter portion 16a of the regulation cylinder 11 from the outside in the radial direction, and the screw thread (Spiral cylinder 12) is elastically compressed and deformed outward in the radial direction. As a result, for example, when an unexpected external force acts on the spiral cylinder 12 (decorative cylinder 20), the regulation cylinder 11 and the spiral cylinder 12 are unintentionally displaced relatively (for example, rattling or rotating). Can be suppressed. Moreover, since the spiral cylinder 12 is in pressure contact with the regulation cylinder 11 in a state of being elastically deformed, the regulation cylinder 11 and the spiral cylinder 12 are compared with the case where the spiral cylinder 12 is pressure-welded to the regulation cylinder 11 without being elastically deformed. The surface pressure between the two can be suppressed, and the relative rotation between the regulating cylinder 11 and the spiral cylinder 12 can be suppressed from being excessively regulated. Further, when the spiral cylinder 12 is formed of an elastomer, the spiral cylinder 12 can be made slippery with respect to the regulation cylinder 11, and when the regulation cylinder 11 and the spiral cylinder 12 are intentionally rotated. In addition, the operation can be realized smoothly.

In order to suppress unintended rattling between the regulation cylinder 11 and the spiral cylinder 12, the top surface 25b (diameter direction) of the thread of the male screw portion 25a is as shown in the feeding container 10A of the first modification shown in FIG. The surface facing the outside) and the bottom surface 24b (the surface facing the inside in the radial direction) of the thread valley of the female thread portion 24a may be pressure-welded in the radial direction. Further, as in the feeding container 10B of the second modified example shown in FIG. 7, the side surface 25c of the thread of the male thread portion 25a (the surface facing the container axis O direction) and the side surface 24c of the thread valley of the female thread portion 24a (container shaft). The surface facing the O direction) may be pressed against the container shaft in the O direction.

When using the feeding container 10, the user grips the regulation cylinder 11 and the decorative cylinder 20 separately and rotates them relatively in the circumferential direction, and rotates the regulation cylinder 11 and the spiral cylinder 12 relatively. Let me. At this time, the locking protrusion 25 is locked to the inner peripheral surface of the vertical hole 23, so that the inner plate 14 rotates with the regulation cylinder 11. When the locking protrusion 25 moves forward along both the vertical hole 23 and the spiral hole 24 and the middle plate 14 advances, the feeding container 10 is in the used state as shown in FIG. 8, and the content A is in a used state. It protrudes forward from the opening on the front side of the container body 13.
After using the content A, the user rotates the regulation cylinder 11 and the decorative cylinder 20 in the circumferential direction relatively opposite to each other, and makes the locking protrusion 25 both the vertical hole 23 and the spiral hole 24. Move backward along. Then, the middle plate 14 retracts, and the content A immerses in the container body 13 from the front opening toward the rear. In this way, the inner plate 14 moves back and forth in the container body 13 in the direction of the container shaft O so that the content A appears and disappears with respect to the opening on the front side of the container body 13.

As described above, according to the feeding container 10 according to the present embodiment, the spiral cylinder 12 is formed of an elastically deformable soft material (a material that is softer and elastically deformable than the material forming the locking protrusion 25). Has been done. Therefore, in a state where the content A protrudes from the container body 13 in the direction of the container axis O, an unexpected external force is applied to the content A, and the external force is transmitted to the spiral cylinder 12 via the content A and the inner plate 14. At that time, the spiral cylinder 12 can be elastically deformed. As a result, the above-mentioned external force can be absorbed by the elastic deformation of the spiral cylinder 12. At this time, although the content A sinks into the container body 13, the content A can be restored and displaced by the subsequent restoration and deformation of the spiral cylinder 12. As a result, it is possible to prevent the content A from being broken or unintentionally subducted. Further, even when the content A is pressed against the portion to be coated and used, the spiral cylinder 12 is elastically deformed according to the pressing force, and the strength of the content A with respect to the portion to be coated is excessively increased. Can be suppressed. From the above, the usability of the feeding container 10 can be improved.

A plurality of vertical holes 23 and locking protrusions 25 are arranged at equal intervals in the circumferential direction. Therefore, when the regulation cylinder 11 and the spiral cylinder 12 are relatively rotated, the entire inner plate 14 can be stably moved back and forth with respect to the container body 13.
The male threaded portion 25a and the female threaded portion 24a have a multi-threaded screw structure. Therefore, for example, as compared with the case where the male screw portion 25a and the female screw portion 24a have a single thread structure, it is possible to keep the pitch P and the lead angle small while securing a large lead L, and the male screw portion 25a and the female screw The contact area with the portion 24a (the contact area between the locking protrusion 25 and the inner peripheral surface of the spiral hole 24) can be easily increased. Therefore, in combination with the fact that a plurality of the vertical holes 23 and the locking protrusions 25 are arranged at equal intervals in the circumferential direction, the unexpected external force applied to the content A is applied to the content A. And can be effectively transmitted to the spiral tube 12 via the inner plate 14.

The locking protrusion 25 is formed in a rectangular shape extending in the container axis O direction in the front view thereof. Therefore, it is possible to secure a contact area between the locking protrusion 25 and the inner peripheral surface of the vertical hole 23, and when the regulation cylinder 11 and the spiral cylinder 12 are relatively rotated, the middle plate 14 is moved. It can be stably rotated together with the regulation cylinder 11.

The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

The front view shape of the locking protrusion 25 does not have to be rectangular, and may be, for example, a perfect circle.
The male threaded portion 25a and the female threaded portion 24a do not have to have a multi-threaded screw structure, and may have, for example, a single-threaded screw structure.
The spiral hole 24 may not be formed by the female threaded portion 24a. For example, the spiral hole 24 may be formed by a single through hole that penetrates the spiral cylinder 12 in the radial direction, and the through hole may extend in a spiral shape in the circumferential direction. In this case, the entire locking protrusion 25 can be arranged in the spiral hole 24.
A plurality of the vertical holes 23 and the locking protrusions 25 may not be arranged at equal intervals in the circumferential direction, and may be arranged unevenly in the circumferential direction, for example.
The spiral cylinder 12 does not have to be attached to the regulation cylinder 11 from the outside in the radial direction. For example, the spiral cylinder 12 may be attached to the regulation cylinder 11 from the inside in the radial direction and may be installed in the regulation cylinder 11. In this case, the holding portion 26 can be arranged in the spiral cylinder 12, and the locking protrusion 25 can be made to enter the vertical hole 23 through the spiral hole 24.

In addition, it is possible to replace the components in the embodiment with well-known components as appropriate without departing from the spirit of the present invention, and the above-mentioned modifications may be appropriately combined.
