Abstract

PROBLEM TO BE SOLVED: To provide a mould for letting-out vessel in good workmanship with a good efficiency in the cold shaping of cosmetics in which a cooling power is uniformly applied to the whole accommodation cylinder of the letting-out vessel. SOLUTION: A mould for shaping cosmetics to be attached to a letting-out vessel of bottom filled type is structured so that a plurality of frame column pieces 4 to be in pressure contact in a small area with the accommodation cylinder 11 of the letting out vessel are dangled at the peripheral edge of a mould plate piece 2 to form a mould surface where the bottoms of the pieces 4 are coupled together by a coupling ring 6 having a diameter larger than the accommodation cylinder 11. Thereby the area contacting with the peripheral surface of the cylinder 11 is lessened as much as possible, and the contact of cold air with the peripheral surface of the cylinder 11 is made smooth and better so that drop of the cooling efficiency is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises, as a part of a molding die, a storage cylinder for accommodating a stick-shaped cosmetic, and a tray body for displacing the cosmetic by sliding up and down while sliding in the storage cylinder. At the same time as the cosmetic is molded, the bottom-filled feeding container that achieves a strong assembling of the molded cosmetic with respect to the saucer,
The present invention relates to a mold generally called "Ojibe", which is assembled as a part of a molding tool when molding cosmetics.

[0002]

2. Description of the Related Art The relative rotation of an outer cylinder and a storage cylinder protruding upward from the outer cylinder causes a tray body in the storage cylinder to slide up and down to be displaced, and a rod-shaped makeup held on the tray body. In a dispensing container for taking in and out of a container, the container and the saucer are used as a part of a mold for forming cosmetics, and molten cosmetic is directly injected and filled into a molding space formed by the container and the saucer. Cooling and solidifying this filled molten cosmetic,
A bottom-fill type feeding container is configured to adopt a method of simultaneously forming a cosmetic and assembling the formed cosmetic to a saucer.

[0003] In the molding of the cosmetic 13 in the bottom-fill-type dispensing container 1 (hereinafter referred to as FIG. 1), an opening of the upper end (the lower end in the figure) of the storage cylinder 11 is sealed with a mold called an ogive. At the same time, in a state in which the saucer body 12 is located at the retreat limit (in the figure, the ascending limit), a fixed amount of the melted cosmetic 13 is injected and filled from the opening of the bottom (the upper end in the figure) of the outer cylinder 10. Then, it is achieved by forcible cooling as it is, and at the same time as the formation of the cosmetic 13 is achieved, a strong and stable assembly of the cosmetic 13 to the saucer 12 is achieved.

The mold used for forming the cosmetic 13 is removed from the feeding container 9 after the formation of the cosmetic 13 is completed. It has a cylindrical shape, and achieves and maintains a strong and stable assembling with respect to the storage cylinder at the cylindrical portion thereof. In addition, it does not damage the surface of the metal storage cylinder 11 and is inexpensive and easy to mold. Manufactured from synthetic resin because of its mechanical strength and easy handling.

[0005]

However, in the above prior art, the entire upper end portion of the storage cylinder is covered with a synthetic resin mold having a poor thermal conductivity.
The cooling efficiency of the storage cylinder part covered with the mold is reduced as compared with the exposed storage cylinder part, and as a result, the cooling and solidification of the entire cosmetic material, that is, the cooling time required for molding the cosmetic material is increased, and the production time is increased. There is a problem that the efficiency cannot be sufficiently increased and that the energy saving becomes a serious adverse effect.

Further, as described above, a difference in the degree of cooling occurs between the exposed portion of the storage cylinder and the portion covered with the mold, so that there is a time lag between cooling and solidification between the molded cosmetic parts. Causes a slight "shrinkage" in the molded cosmetic.
Or a molding defect such as "bending" occurs, thereby causing a problem of impairing the product image.

Therefore, the present invention has been made to solve the above-mentioned problems in the prior art, and the cooling power is evenly applied to the entire storage cylinder of the delivery container when the cosmetic is cooled in the bottom-filled delivery container. It is an object of the present invention to make cooling work of cosmetics efficient, and to achieve good cooling formation of cosmetics.

[0008]

Means for solving the above problem is to form a cosmetic by using a storage cylinder and a tray body which moves up and down while sliding in the storage cylinder as a part of a molding die. At the same time, it is a mold for cosmetics molding that is assembled to the bottom-filled feeding container that achieves assembly to the saucer body,
It has a mold plate piece that brings the peripheral edge surface of the inner surface forming the molding die surface into close contact with the opening end surface of the container cylinder of the container, and the outer peripheral surface of the container cylinder of the container that is extended from the outer peripheral end of the mold frame piece to the inner surface. A plurality of frame pillars protrudingly provided with a press contact vertical line that presses with a small contact area are spaced apart and suspended, with the inner diameter larger than the outer diameter of the storage cylinder of the container by extending between the lower ends of the frame pillars Connecting with a connecting ring piece.

[0009]

In the state where the mold is assembled into the storage cylinder of the feeding container in a state where the upper end opening of the storage cylinder is hermetically sealed and fitted externally, the peripheral edge surface of the mold plate piece is positioned at the upper end opening of the storage cylinder. Closely contact, seal the bottom of the cosmetic molding space formed by this storage cylinder, and press against the outer peripheral surface of the storage cylinder by pressing the vertical ribs of the frame column pieces with a small contact area, Achieve and maintain assembly with the storage cylinder.

[0010] The assembling of the formwork with respect to the outer peripheral surface of the storage cylinder of the feeding container is such that the press-contacting vertical line of the frame column is pressed against only a small contact area, and the press-contact vertical line of the frame column is press-contacted. The outer peripheral surface of the storage cylinder other than the location is opened through a window formed between the frame and column pieces.

[0011] The space between the frame pillar pieces opened outward by the window is:
The frame column piece is suspended from the outer peripheral surface of the frame plate piece that makes the opening end face of the storage cylinder closely contact the peripheral edge surface, so that it is open upward and the inner diameter of the engagement ring piece is stored. Since the outer diameter of the cylinder is also large, a gap is formed between the coupling ring piece and the storage cylinder.

[0012] Therefore, the cool air supplied to the surface of the storage cylinder for cooling and solidifying the cosmetic will surely and smoothly come into contact with the surface of the storage cylinder through the window between the frame pillar pieces. Moving contact flow to the outer cylinder surface is well achieved through the windows and voids.

[0013] As described above, the outer peripheral surface of the storage cylinder of the feeding container in which the form is externally fitted is used for cooling and solidifying the cosmetic except for a small portion of the frame column piece where the vertical pressing line is pressed. , And the small parts of the frame columns that are pressed against the pressing vertical stripes are scattered in a metal storage tube with good thermal conductivity. The cooling of the cosmetic in the cylinder does not become uneven.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a state in which a mold 1 according to the present invention is externally fitted to an opening of a storage cylinder 11 of a feeding container 9 to cool and inject and fill a cosmetic 13.
While the mold 1 is closely fitted to the opening of the upper end (the lower end in FIG. 1) of the upper end 1 and the pan 12 is positioned at the retreat limit (the ascending limit in FIG. 1), a fixed amount of The molten cosmetic 13 is injected and filled into the storage cylinder 11 through an opening formed at the lower end (the upper end in FIG. 1) of the outer cylindrical body 10 of the feeding container 9, and in this state, the whole is forcibly cooled to make up the makeup. An amount of 13 cooling solidification is achieved.

The mold plate piece 2 of the mold 1 is formed in a thin plate shape having a peripheral edge surface 3 closely contacting the opening end surface of the storage cylinder 11 on the peripheral edge of the inner surface serving as a molding die surface. The overall shape is elliptical in accordance with the opening end surface of the storage tube 11 obtained by cutting the cylindrical body obliquely.

The six frame post pieces 4 suspended from the peripheral end of the template 2 are provided at equal intervals along the circumferential direction to form windows 7 of equal size therebetween. , Pressing vertical stripe 5
Is protruded outward from the peripheral end of the template 2 by an amount corresponding to the projecting height of the template 2.

The pressing vertical strip 5 projecting from the frame column piece 4 is
The flat section has a substantially semicircular ridge structure, and the lower edge thereof is chamfered in an arc shape so that the outer fitting of the mold 1 to the storage tube 11 can be smoothly performed. .

By connecting the lower ends of the frame post pieces 4 to each other, the coupling ring piece 6 that exerts a strong and stable assembling force on the storage cylinder 11 to the frame post piece 4 has the same thickness as the frame post piece 4. Therefore, the width of the gap 8 formed between the storage cylinder 1 and the outer peripheral surface of the storage cylinder 1 is equal to the protruding height of the press contact vertical streak 5.

[0019]

Since the present invention has the above-described structure, the following effects can be obtained. Since the contact area of the feeding container with the outer peripheral surface of the storage cylinder is small, the area of contact with the cooling air on the outer peripheral surface of the storage cylinder by mounting the mold hardly decreases, so that the mold cools the cosmetics due to the cool air. Does not deteriorate.

Since the concave space formed in the outer peripheral surface of the storage cylinder by assembling the mold is open to the outside and the vertical direction, the cooling air flows smoothly on the outer peripheral surface of the storage cylinder. Therefore, the assembled formwork does not hinder the cooling operation of the cool air.

The external fitting of the form to the storage cylinder is achieved and maintained by the press-contact of the projecting ends of the press-contact vertical strips of the respective frame columns provided between the mold plate and the connecting ring. So
The press contact of the longitudinal ribs to the outer peripheral surface of the storage cylinder can be made sufficiently elastic, so that safe attachment / detachment to the storage cylinder requiring a beautiful appearance and strong attachment can be obtained.
