Description

  The present invention relates to a method and apparatus for manufacturing a so-called stick cosmetic such as a stick-type foundation, concealer, lipstick, and lip balm, and a heat transfer jig, and in particular, a cooling temperature at the time of cooling and solidifying a melted solid cosmetic. It relates to a device that improves controllability.

  Conventionally, the manufacture of so-called stick-shaped cosmetics such as stick-type foundations, stick-type concealers or stick-type lipsticks, lip balms, etc. has been carried out in a plurality of transport holders arranged in multiple rows, also called bags, installed in a conveyor device such as a belt conveyor. Each one of the feeding containers is press-fitted and held, and solidified while being transported horizontally.

  The various delivery containers held by the respective transport holders here are made of resin or metal and filled with a melted solid cosmetic material, and are configured to deliver the solid cosmetic material after cooling and solidification. Is.

  In a conventional manufacturing process of this type of bar-shaped cosmetic material, as described in Patent Document 1, first, a feeding container is press-fitted and held in each conveyance holder. Next, the feeding container held by the transport holder is transported horizontally together with the transport holder by the belt conveyor, sent to the filling process, and filled with the melted and liquefied solid cosmetic through the filling nozzle. After this filling, the feeding container is transported to the next flattening process by a belt conveyor, and a far infrared heater is used to eliminate the unevenness generated on the upper end surface of the solid cosmetic. Then, the upper end of the solid cosmetic is remelted and flattened by irradiating it with heat rays. Thereafter, the feeding container containing the warm and softened solid cosmetic is further conveyed horizontally to the cooling chamber by the belt conveyor.

The cooling chamber is composed of a plurality of cooling tanks that are connected so that the temperature is lowered in stages, and is divided according to the temperature hierarchy. It is comprised so that it may cool, letting you pass through. The feeding container passing through the cooling chamber and the solid cosmetic filled in the feeding container are cooled in accordance with the temperature distribution of each cooling tank installed in a stepwise manner to complete solidification.
Japanese Patent Laid-Open No. 02-291805

  Conventional conveyance holders convey conveyance containers in a plurality of rows because of the necessity for mass production. For this reason, the cooling chamber has a large internal volume, and the temperature differs at the center and corners of the cooling chamber.In the case of small-volume production, the cooling temperature varies depending on the location of the cooling chamber through which the bar-shaped cosmetic material passes. It was difficult to cool under conditions. For this reason, when the solid cosmetic is solidified by cooling, molding defects such as sinks, creases, pinholes, and stripes occur, which has a great influence on mass production quality. Furthermore, the time required for the process from the press-insertion to the removal of the feeding container with respect to the conventional holder for the manufacture of the stick-shaped cosmetic material takes about 25 minutes, so if it is judged that the quality has been rejected, it takes a long time to recover. It takes time.

  The present invention has been made in view of the above problems, improves temperature controllability related to heating and cooling, eliminates product variations when solid cosmetics solidify, and enables stable and uniform product production. In addition, the present invention is intended to provide a manufacturing method, a manufacturing apparatus, and a heat transfer jig for a bar-shaped cosmetic material that can be used easily and inexpensively even with a feeding container having various external specifications.

In order to solve the above-mentioned problems, the means employed in the method for manufacturing a bar-shaped cosmetic of the present invention includes a transporting process for moving the holding container, a preheating process for preheating the feeding container, and a molten solid cosmetic.

It is characterized by.

Further, in the preheating process, the heating member is brought into contact with the outer peripheral surface of the heat transfer jig, and the heating is uniformly applied from all directions of the outer periphery of the cylindrical portion in which the solid cosmetic of the feeding container is accommodated toward the axis. It is characterized by warming.

Further, in the cooling step, the cylindrical portion in which the solid cosmetic material of the feeding container is accommodated is uniformly distributed from all the outer circumferences toward the axis while the cooling member is brought into contact with the outer circumferential surface of the heat transfer jig. It is characterized by cooling.

Further, the means adopted in the manufacturing apparatus includes a conveying means for moving the holding container while holding it, a preheating means for preheating the feeding container, and filling the molten solid cosmetic into the feeding container via a filling nozzle. In a stick-shaped cosmetic manufacturing apparatus having at least a filling means and a cooling means for cooling the melted solid cosmetic, the pre-heating means or the cooling means accommodates the solid cosmetic in the feeding container held vertically. that on the outer peripheral surface of the cylindrical portion, the thickness disc heat transfer jig ing the thickness direction into the through hole from the heat transfer properties of the material provided in the center of the extrapolated wearing, thermally conductive jig A heating member or a cooling member is brought into contact with the outer peripheral surface of the cylindrical member, so that preheating or cooling is performed uniformly from all directions of the outer periphery of the cylindrical portion toward the axis .

  According to the present invention, in the manufacture of a bar-shaped cosmetic, a substantially cylindrical heat transfer jig made of a heat-transferable material is attached to the outer surface of the portion of the feeding container in which the solid cosmetic is stored, and cooling is performed. As a result, variations in the product due to cooling and solidification are eliminated, and stable and uniform bar-shaped cosmetics can be produced without forming defects such as sink marks, creases, pinholes, and streaks. Moreover, it is possible to produce a wide variety of bar-shaped cosmetics simply by exchanging the transfer holder and the heat transfer jig, and it is not necessary to make a large-scale production line change and is suitable for small-lot production of various varieties.
