Description

BACKGROUND OF THE INVENTION
The present invention relates to an improved cosmetic filling nozzle.
[Prior art]
Conventionally, when filling various cosmetic agents into a cosmetic container, various means for heating a filling nozzle have been tried in order to improve the quality of the produced cosmetic.
For example, as shown in FIG. 4, by using radiant heat from an infrared electric heater 35 surrounded by a reflector plate 34, hot air is blown to the filling nozzle 30 held by the nozzle plate 31 to be emitted from the filling nozzle 30. As shown in FIG. 5, using the electric heater 40 or the like as a heat source, hot air is created with compressed air, and hot air is blown from the heat nozzle 41 to the filling nozzle 30, as shown in FIG. 5. A method of heating a cosmetic to be injected is known.
Incidentally, FIG. 4, reference numeral 32 in FIG. 5 is a heater provided in the nozzle plate 31.
[Problems to be solved by the invention]
However, in the case of the filling method of various cosmetics using the conventional filling nozzle 30 described above, the setting and management of the humidity immediately before filling greatly affects the quality of the product after filling.
This is because, in the case of the conventional nozzle heating method, the temperature of the cosmetic in the filling nozzle 30 abruptly varies depending on conditions such as variations in operation downtime, air conditioning conditions in the workplace, room temperature, and breeze around the filling nozzle 30. The temperature rises to 120 ° C or higher (the normal filling temperature is in the range of 60 ° C to 100 ° C, within the set temperature ± 1 ° C is the optimum condition), and the cosmetic raw materials are in a decomposed state. This is due to the fact that there is a fatal defect that makes it impossible to maintain the quality, and a few shots have to be discarded immediately before production.
The present invention has been made in view of the above circumstances, and even when external conditions change, the filling temperature can be kept constant, and the cosmetics produced by filling can be made high quality. An object is to provide a nozzle for filling a cosmetic agent.
[Means for Solving the Problems]
The filling nozzle of the cosmetic agent according to the invention of claim 1 is supported by the nozzle plate, the inner cylinder through which the filling cosmetic agent passes, and the outer cylinder disposed on the outer periphery of the inner cylinder; A nozzle part having a pair of symmetrical partitions in which a space between the inner cylinder and the outer cylinder is used as a medium passage through which a temperature adjusting medium can circulate, and a blind plug arranged at the lower end of the inner cylinder and the outer cylinder A temperature adjusting medium that is heated or cooled is circulated in a medium passage partitioned by the pair of partitions of the nozzle portion, so that the temperature of various cosmetics passing through the inner cylinder is maintained at a set temperature. It is characterized by that.
According to the present invention, the filling cosmetic agent is allowed to pass while the heated or cooled temperature adjusting medium is passed through the medium passage partitioned by the pair of partitions and the blind plug between the inner cylinder and the outer cylinder of the nozzle portion. As in the first aspect of the invention, by passing through the inner cylinder and filling the target location, external conditions such as variations in operation downtime, air-conditioning conditions in the workplace, room temperature, light wind around the filling nozzle 30, etc. Even when is changed, the filling temperature of the cosmetic agent can be kept constant, and the cosmetics filled and produced can be of high quality.
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail.
Figure 1 is a Ru der shows a double jacket nozzle 30 as a cosmetic agent filling nozzle of an embodiment of the present invention.
The double jacket nozzle 30 is configured to keep the temperature of the cosmetic agent inside the nozzle portion 20 for filling various cosmetic agents constant and constant under a certain condition without being influenced by external factors. is there.
The double jacket nozzle 30 is composed of a manifold plate 2, a nozzle plate 3, a nozzle head 4, an inner cylinder 7, and a nozzle portion 20 including an outer cylinder 8, and cools the space in the inner cylinder 7. Alternatively, the heated medium is passed, the entire nozzle part 20 is cooled or heated, and the cosmetic agent is passed through the cosmetic agent passage 1 that penetrates the manifold plate 2, the nozzle plate 3 and the central part of the inner cylinder 7, and the cosmetic agent The mechanism can adjust the temperature freely.
The inner cylinder 7 is an inner cylinder 7 shown in FIG. 1 by cutting a thin stainless steel (SUS) pipe into a predetermined length.
The outer cylinder 8 is also made of stainless steel, and a partition inner cylinder is provided by providing a pair of partitions 9a and 9b symmetrically arranged in the direction shown in FIG. 1 (the length direction of the outer cylinder 8) between the inner cylinder 7 and the outer cylinder 8. The medium passages 10a and 10b are formed on the outer periphery of the outer wall 7, and the medium inlet hole 16 and the medium outlet hole 17 are provided in the upper position of the outer cylinder 8 from the direction of 90 degrees with respect to the partitions 9a and 9b.
Further, the medium injection hole 3 a provided in the nozzle plate 3 communicates with the medium inlet hole 16, and the medium discharge hole 3 b provided in the nozzle plate 3 communicates with the medium outlet hole 17.
Further, below the nozzle portion 20, the partitions 9 a and 9 b are removed over a section of several mm from the lower end thereof, thereby forming a medium conduction path 10 c that goes around the outer periphery of the inner cylinder 7.
Further, the upper end of the inner cylinder 7 is welded to the nozzle head 4 in the nozzle plate 3, and the outer cylinder 8 is inserted and fixed to the outer periphery of the inner cylinder 7 using the O-ring plate 12 and the O-ring 13. The stopper 11 is welded to the lower ends of the outer cylinder 8 and the inner cylinder 7, and the lower part of the conduction path 10c has a sealed structure.
With such a configuration, a medium flow path is formed from the medium injection hole 3a to the medium inlet hole 16, the medium passage 10a, the conduction path 10c, the medium passage 10b, the medium outlet hole 17, and the medium discharge hole 3b. ing.
In addition, the inner cylinder 7 and the outer cylinder 8 can be manufactured by setting their inner diameter, outer diameter, and total length freely.
Such an assembly becomes the double jacket nozzle 1, and although not shown, the inner cylinder 7 and the outer cylinder 8 of the nozzle portion 20 of the double jacket nozzle 1 can have the inner diameter, outer diameter, and total length freely according to the shape of the cosmetic container. Although only one is selected in FIG. 1, a plurality of nozzle plates 3 are set and used for filling an actual cosmetic.
That is, a plurality of double jacket nozzles 1 are set in the nozzle pot 3 described above, and a medium which is cooled or heated and is appropriately heated is supplied from the medium injection hole 3a of each double jacket nozzle 1, and medium inlet holes 16, The medium is discharged to the medium discharge hole 3b through the medium passage 10a, the conduction path 10c, the medium passage 10b, and the medium outlet hole 17.
Thereby, the medium circulates and the temperature of the nozzle portion 20 can be controlled so as not to cause a temperature error in the plurality of double jacket nozzles 1.
As a result, even if various conditions such as variations in operation stop time, air conditioning conditions in the workplace, room temperature, and breeze around the nozzle portion 20 change, makeup filled through the cosmetic passage 1 in the nozzle portion 20 is filled. The temperature of the agent can always be maintained at a preset constant temperature, whereby the quality of the cosmetic to be filled and molded can be improved.
【The invention's effect】
According to the first aspect of the present invention, even when the external conditions change, the cosmetic filling temperature can be kept constant, and the cosmetics filled and produced can be of high quality. Nozzle for filling can be provided.
