Description

  The present invention relates to a stick-shaped cosmetic material feeding container such as lipstick or solid blusher. In particular, the present invention relates to a method for holding these stick-shaped decorative materials.

As a conventional example, FIG. 5 shows a stick-shaped decorative material feeding container for storing lipstick and the like, in which the stick-shaped decorative material is inserted and held through the opening at the tip of the sleeve, and the lipstick and the sleeve are rotated synchronously. Is disclosed. This figure is extracted from FIG. 13, which is the third embodiment of Japanese Patent Application Laid-Open No. 2002-262936, but the system of the feeding mechanism is conventionally known.
As shown in FIG. 5A, the stick-shaped decorative material manufactured with a soft texture such as lipstick forms a slope whose tip is matched to the cut of the sleeve tip, and the lower part is a reduced diameter part 271 by a reduced diameter step part 270. This portion is forcibly fitted into the cavity 231a formed by the decorative material holding part 231 as shown in (a '), and the external dimensions of the stick-shaped decorative material a and the external dimensions of the decorative material holding part 231 are the same. The size of the sleeve 210 in (A) is designed so that the inner diameter of the rod-shaped decorative material a and the outer diameter of the decorative material holding portion 231 does not contact the inner periphery of the sleeve 210, and means for sliding in the sleeve 210 is taken. (Refer to BB cross section). Further, as shown in (a ′), the rod-shaped decorative material a can be fitted into the cavity portion 231a of the cosmetic material holding portion 231 even with the core chuck member 230 alone, and the cross-section of the cavity portion 231a and the reduced diameter of the rod-shaped decorative material a. The section of the portion 271 is manufactured with a size that can be fitted.

  Since the rod-shaped decorative material a has the reduced diameter portion 271 including the reduced-diameter stepped portion 270, the rod-shaped decorative material a 'is inevitably formed by splitting with a mold. Further, since the reduced diameter portion 271 has a smaller diameter than the size of the upper portion, distortion occurs in this portion, and restrictions are imposed on the manufacturing prescription of the rod-shaped decorative material, and the portion becomes easier to break.

  Furthermore, since there is a gap between the outer diameter of the decorative material holding portion 231 and the inner diameter of the sleeve 210, the longer the stick-shaped decorative material a is in the axial direction, the greater the risk of contact with the sleeve inner diameter when sliding, thus reducing the commercial value. It was the cause.

A plurality of sliding grooves are arranged along the substantially circular through-hole in the sleeve, and a plurality of convex pieces located in the sliding groove are provided at the tip of the core chuck member, and the convex pieces are formed of a thin film. They are connected to form a cavity, and this cavity serves as a holding part for fitting the stick-shaped decorative material, and the outer periphery of the thin film abuts against the ridge formed between the sliding groove in the sleeve. It is a measure that touches.

  In a second aspect of the invention, the core chuck member is formed of plastic by injection molding, and the cavity portion constituting the holding portion forms a pseudo circle having elasticity, and the holding is held in a plurality of sliding grooves in the sleeve. Means is provided for correcting the cavity formed by the thin film into a substantially circular shape by positioning the convex piece of the portion.

  In the third invention, means for limiting the thickness of the thin film from 0.05 mm to about 0.3 mm is taken.

The present invention will be described in detail with reference to the drawings.
FIG. 1 is a longitudinal sectional view of a main body 2 showing a stick-shaped cosmetic material feeding container 1 of the present invention, and a view showing a cap 3 that can be attached to and detached from the main body 2. FIG. (A) Sleeve 10, (B) Main body cylinder 20, (C) Core chuck member 30 are shown in a three-dimensional view and an arrow view.

Further, the AA cross section of FIG. 1 is shown in (F) for an empty container (before filling with a stick-shaped decorative material), and (G) for an actual container (filled with a stick-shaped decorative material) for a detailed description of the present invention. ing.

It demonstrates from each member of FIG.
(A) The sleeve 10 is a cylindrical body having a tip opening hole 11 having a substantially circular shape 10a, and a through hole 14 having a substantially circular shape 10a is formed therein. Eight sliding grooves 12 are provided along the through hole 14 on the inner diameter, and the sliding grooves 12 are arranged in the sliding through hole 14a except for the flat portion of the front end through hole 14b. Further, an engagement protrusion 13 is provided on the outer diameter, and it fits in the recess 23 of the main body cylinder 20 so as to be rotatable and not detachable.

(B) The main body cylinder 20 has a cylindrical shape with a cap locking projection 22 formed on the upper part formed by the outer cylinder 21, and a helical part in which the concave part 23 and the core chuck member 30 are screwed and slid in the axial direction on the inner diameter The stroke length 24 is formed.

(C) The core chuck member 30 is formed with a rod-shaped decorative material holding portion 31 in which the inner periphery of eight convex pieces 32 are connected to the tip by a thin film 33, and a rod shaft 36 having a smaller diameter than the holding portion 31 is extended. At the same time, a cylindrical portion 37 having a diameter larger than that of the rod shaft 36 is provided below the rod shaft 36, and a screw projection 38 is disposed on the outer periphery of the cylindrical portion 37. In the embodiment, the inner periphery of the convex piece 32 is connected by the thin film 33 to form the cavity 34, but four of the eight convex pieces slightly protrude in the inner diameter direction to lock the stick-shaped decorative material. It may be used as a rib.

  The rod-shaped decorative material feeding container 1 of FIG. 1 has a sleeve 10 and a main body cylinder 20 assembled in a rotatable and non-detachable manner, and a core chuck member 30 having a rod-shaped decorative material holding portion 31 at its tip is inserted. By positioning the convex piece 32 provided on the holding portion 31 of the core chuck member 30 in the sliding groove 12 of the book, a rotation stopping function is formed, and the core chuck is connected to the spiral portion 24 screwed into the main body cylinder 20. A screwing mechanism is configured by engaging a screwing protrusion 38 protruding from the outer periphery of the cylindrical portion 37 of the member 30.

  By rotating the sleeve 10 and the main body cylinder 20 in this state, the rod-shaped decorative material fitted to the holding portion 31 advances and retreats from the opening opening 11 of the sleeve 10 while rotating synchronously with the sleeve 10. Yes.

  The arrow view shown in FIG. 2C is indicated as a circle having a radius X when the drawing is produced, and the cavity 34 in the three-dimensional view is drawn as being formed in a substantially circular shape. However, when a circular member having eight convex pieces at the tip of the core chuck member 30, which is a feature of the present invention and whose inner periphery is connected by a thin film, is molded from thermoplastic by injection molding, FIG. The cavity 34 formed of the thin film 33 is formed as a pseudo circle 34a having radii X + α and X−α from the center point, unlike the substantially circular shape having the radius X of the design dimension, as shown in FIG. The holding portion 31 having an outer diameter different from the inner diameter of the substantially circular shape 10a drilled in the inner diameter of the sleeve 10 is formed. Moreover, since this holding | maintenance part 31 is connected with the thin film 33, it has the elasticity which is easy to deform | transform.

Since the pseudo circle 34a does not have a dimension that matches the substantially circular cross section of the rod-shaped decorative material, it is difficult to fit the rod-shaped decorative material with the core chuck member 30 alone, and this point is the conventional cup-shaped holding portion. And different characteristics.
The pseudo circle 34a will be further described. Since the plastic melted at the time of injection molding flows into the thin film 33 from the thick convex piece 32 that easily flows, a difference in internal stress occurs between the convex piece 32 and the thin film 33. This is a deformation that occurs because the core pin slightly moves depending on the pressure and speed of the plastic at the time of injection molding and causes a thin uneven thickness in the thin film 33, and is not always a constant deformation. The thin film 33 is preferably thin if the stick-shaped decorative material can be held without destroying the cavity 34, and is preferably about 0.3 mm with 0.05 mm being the minimum thickness. The deformation state of the pseudo circle 34a corresponds to the thickness of the thin film 33, and the thinner the thin film 33, the larger the deformation. In the embodiment, for example, when the thickness of the thin film 33 is set to about 0.1 mm at the tip and about 0.2 mm at the bottom, the wall thickness varies due to the slight movement of the core pin described above. 0.08 mm at the bottom and 0.18 mm at the bottom, which is thinner than the setting, and on the other side, the thickness is thicker, such as 0.12 mm at the tip and 0.22 mm at the bottom. Such uneven thickness tends to occur, and the pseudo circle 34a is generated only by this.

  In the holding part 31 shown in (E), two opening windows 39 are formed side by side in the thin film 33 so as to be 90 degrees symmetrical. This is such that the core pin of the mold constituting the cavity 34 is prevented from moving as much as possible by the pressure and speed at the time of injection molding. The thinner the thin film 33, the more effective.

  (F) shows the AA cross section in the main body 2 of the stick-shaped cosmetic material feeding container 1 of the present invention shown in FIG. 1, and the tip opening hole 11 and the through hole 14 of the sleeve 10 are formed in a substantially circular shape 10a. FIG. 6 is a view showing that the protruding piece 32 of the holding portion 31 shown in (D) of the core chuck member 30 is accommodated in the sliding groove 12 and the pseudo circle 34a is corrected to be nearly circular. At this time, the outer periphery 33b of the thin film 33 is composed of eight pieces, and some of the thin films 33 come into contact with the ridge 12a formed between the sliding groove 12 and the sliding groove 12 provided in the sleeve 10 to cause sliding friction. Causes resistance. It is a feature of the present invention that the cavity 34 formed by the thin film 33 by this correction is a cavity 34 having a substantially circular cross section into which a rod-shaped decorative material having a substantially circular cross section can be fitted.

  Therefore, when the core chuck member 30 of the present invention is inserted into the sleeve 10, it does not spontaneously fall. In the conventional cosmetic material holding portion 231 of FIG. 5, the decorative material holding portion 231 in the sleeve 210 is naturally designed to fall naturally. In the feeding container of the present invention, since the outer periphery of the holding portion 31 comes into contact with the sleeve 10, there is no vibration in the sleeve when the stick-shaped decorative material slides, so that the stick-shaped decorative material does not adhere to the sleeve 10. A high-quality feeding container can be provided.

  In the embodiment, eight sliding grooves 12 are arranged in the sleeve 10 having the through hole 14 having a substantially circular 10a and the convex pieces 32 of the holding portion 31 are eight pieces. However, the present invention is not limited to this. The sliding groove 12 may be four or six, and the convex piece 32 may be four or six pieces.

  In any case, the thin film 33 forming the pseudo circle abuts against the ridge 12a between the sliding groove 12 and the sliding groove 12 in the state of an empty container.

FIG. 3 (G) shows a cross-sectional view in which the stick-shaped decorative material A of FIG. 4 (H) is fitted into the cavity 34 which is the empty container of FIG. 3 (F). The holding part 31 itself is changed from a soft elastic cavity part 34 to a rigid holding part by sticking tightly and supporting the cavity part 34 from the inside. Therefore, according to the present invention, in the production of a bar-shaped decorative material, an invention can be provided that can hold not only a mold having a reduced diameter portion but also a stick-shaped decorative material by extrusion molding and a powdered bar-shaped decorative material. It is.

It is a partial longitudinal cross-sectional view which shows the stick-shaped cosmetic material delivery container of this invention. It is the three-dimensional figure and arrow view of each member used in the stick-shaped cosmetic material delivery container of FIG. (A) shows a sleeve, (B) shows a body cylinder, and (C) shows a core chuck member. The holding | maintenance part of the core chuck | zipper member currently used with the stick-shaped cosmetic material delivery container of FIG. 1 is shown with the three-dimensional view and the arrow view. (E) shows another form, (F) shows the state of the AA cross section when it is empty, and (G) shows the state of the actual container. It is a three-dimensional view showing various forms of a stick-shaped decorative material. This is a conventional example.
