Description

  The present invention relates to a filling method for a refill container for powder cosmetics, and more particularly to a filling method for a non-compressed type powder cosmetic filling a refill container without compressing the powder cosmetic.

  In recent years, a refill container that can be easily removed and replaced from a compact body as a main body is put on the market from the economical viewpoint. Cosmetics filled in such refill containers include pressed powder type (solid), liquid type (liquid), and loose powder type (powder). Of these, loose powder type cosmetics are pressed powder type. Unlike those, it has a feature that it can have a light touch feeling and a good stretch feeling.

  By the way, as a general method for filling the above-mentioned cosmetic into a refill container, there is known a method of filling powder or slurry-like cosmetic with a filling nozzle from above the opening of the container (Patent Document). 1, 2). In the case of such a filling method, the pressed powder type cosmetic has a step of compressing the cosmetic after filling, and the liquid type has a flowability of the cosmetic because the cosmetic itself has fluidity. There was no particular difficulty in reducing the bulkiness and making the container thin and compact.

  However, unlike the pressed powder type cosmetics, the loose powder type cosmetics do not have a step of compressing the cosmetics after filling, and do not have fluidity like the liquid type. Then, there was a risk that the powdered cosmetic would be wiped out or overflowed from the container. Therefore, the loose powder type cosmetic container has to adopt a container with a high volume ratio like the jar type container shown in FIG. 4 in order to prevent wiping and overflowing at the time of filling. There was a problem in terms of.

  Hereinafter, an example of an embodiment of a non-compression type powder cosmetic filling method according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view of a refill container used in the non-compressed powder cosmetic filling method of the present invention, and FIG. 2A is a filling nozzle in a filling hole in the non-compressed powder cosmetic filling method of the present invention. FIG. 2 (b) is a diagram schematically showing the process of filling cosmetics into the container via the filling nozzle, and FIG. 2 (c) is cosmetic filling. It is the figure which showed typically the process of sealing a filling hole later. In the figure, 1 is a container body, 2 is a sealing lid, 3 is a sealing seal, 4 is a mesh net, 5 is a foam sheet, 6 is a filling nozzle, 11 is a peripheral wall, 12 is a bottom, 13 is a filling hole, and 14 is a flange. Part, 15 is a storage part, 16 is a gap, 61 is a stopper, and A is a powder cosmetic.

  As shown in FIG. 1, the refill container used in the filling method of the present invention has a peripheral wall 11 suspended from the bottom 12 and is formed in a bottomed dish shape capable of storing cosmetics inside, A filling hole 13 is formed in the center of the bottom portion 12. Further, a flange portion 14 protrudes outward from the upper end of the peripheral wall 11. The container body 1 is preferably made as thin and compact as possible in consideration of portability. Specifically, it is desirable to form the container body 1 so that the height is 30 mm or less. The filling hole 13 has such a size that the filling nozzle 6 can be inserted, and when the filling nozzle 6 is inserted, a gap 16 is formed between the outer peripheral surface of the filling nozzle 6 and the edge of the filling hole 13. Preferably, the opening diameter is 10 to 20 mm.

  The upper opening of the container body 1 is sealed with a seal lid 2 before filling with cosmetics. Specifically, the opening is sealed by sticking the seal lid 2 on the upper surface of the flange portion 14 of the container body 1. The sticking means of the seal lid 2 is not particularly limited as long as it can withstand the pressure and transportation during the filling of the cosmetic, and can be easily peeled off from the flange portion 14 during use, and known adhesive means and the like can be applied. Moreover, there is no special restriction | limiting about the material of the container main body 1 and the seal lid 2, The material generally used can be used. That is, any combination is possible as long as they can be bonded by the flange portion 14 and can be peeled off. Among these, preferable examples of the container body 1 include polypropylene, ABS, SAN, PET, and the like, and preferable examples of the seal lid 2 include resin film, pulp paper, synthetic paper, and the like.

  Next, a series of steps of the non-compression type powder cosmetic filling method of the present invention will be described with reference to FIGS. 2 (a) to 2 (c). As a filling device used in the filling method of the present invention, a conventional powder cosmetic filling device can be basically used. As described above, the filling nozzle 6 of this embodiment has an outer diameter that allows a gap 16 to be formed between the outer peripheral surface of the filling nozzle 6 and the edge of the filling hole 13 when inserted into the filling hole 13. It is preferable to use a filling nozzle having an outer diameter of 9 to 19 mm. The width of the gap 16 can be arbitrarily determined according to the relationship between the opening diameter of the filling hole 13 and the outer diameter of the filling nozzle 6, but a preferable range is 0.4 to 0.6 mm, and particularly 0.5 mm is desirable. . Furthermore, the filling nozzle 6 of this embodiment is provided with a stopper 61 that protrudes from the outer peripheral surface near the tip of the filling nozzle 6 so as to come into contact with the container bottom 12 when inserted into the filling hole 13. With the stopper 61, the filling nozzle 6 can be inserted into the filling hole 13 to an appropriate depth.

  First, the seal lid 2 is attached to the upper surface of the flange portion 14 of the container body 1 to seal the upper opening. Next, it arrange | positions so that the filling hole 13 may be exposed to the upper opening side down. In this state, the filling nozzle 6 is inserted into the filling hole 13 as shown in FIG. At this time, if the tip of the filling nozzle 6 is inserted into the filling hole 13 to an appropriate depth, the stopper 61 comes into contact with the container bottom 12, so that it can be prevented from being inserted further by mistake. The insertion depth of the filling nozzle 6 is preferably such that the tip of the filling nozzle 6 protrudes from the filling hole 13 into the storage portion 15 by 0 to 2 mm.

  Next, as shown in FIG. 2 (b), the powder cosmetic A is filled into the storage portion 15 through the filling nozzle 6. The cosmetic is filled by extrusion filling with a screw or spray filling with air pressure. Since the opening of the container body 1 is sealed by the seal lid 2, the storage portion 15 is in a sealed state except for the filling hole 13, but the air fed into the storage portion 15 is indicated by an arrow. As shown by, it is possible to escape from the gap 16 between the periphery of the filling nozzle 6 and the edge of the filling hole 13 to the outside. Thus, even in a substantially sealed space, the cosmetic can be filled without fear of wiping out of the container or overflowing.

  After the cosmetic filling is completed by the above operation, the filling hole 13 is sealed with the sealing seal 3 as shown in FIG. Thereby, a series of processes of the non-compression type powder cosmetic filling method according to the present invention is completed.

  Further, a mesh net 4 may be provided at the opening of the container body 1. Such a mesh net 4 is preferable because the cosmetic powder is less likely to harden after being opened, so that the usability is improved. Examples of the material of the mesh net 4 include nylon, polyester, or a mixture of nylon and polyester. The filling method of the refill container of this aspect is that the mesh net 4 is pasted on the opening in advance before the opening of the container body 1 is sealed with the sealing lid 2, and the sealing lid 2 is sealed from above. Thereafter, filling may be performed according to the above-described method.

  Furthermore, in the filling method according to the present invention, in the case of a container in which the mesh net 4 is attached to the opening, as shown in FIG. 3, a foam sheet 5 may be interposed between the mesh net 4 and the seal lid 2. good. Thereby, it becomes difficult for powder cosmetics to adhere to the sealing surface of the seal lid 2, and therefore, powder contamination at the time of opening can be minimized. The foam sheet 5 can be appropriately selected from a method of placing on the mesh net 4 and a method of sticking to the back surface (the storage unit 15 side) of the seal lid 2. The filling method in the former case is that the mesh net 4 is pasted on the opening in advance before the opening of the container body 1 is sealed with the seal lid 2, and the foam sheet 5 is placed on the mesh net 4. Then, the opening is sealed from above with the sealing lid 2 to sandwich the foamed sheet 5, and thereafter, filling may be performed according to the above-described method. Further, the filling method in the latter case is such that the mesh net 4 is pasted on the opening in advance before the opening of the container body 1 is sealed with the seal lid 2, and the foam sheet 5 is pasted on the back side in advance from above. What is necessary is just to fill with the above-mentioned method after sealing with the sealed lid | cover 2 which was made. The foamed sheet 5 may have any elasticity and air permeability, and preferable examples thereof include a foamed polyethylene sheet and high-quality paper. The thickness of this is not particularly limited, but is preferably about 0.8 to 1.2 mm.

  Furthermore, in the method of placing the foam sheet 5 on the mesh net 4 described above, an elastic layer having a certain thickness may be formed in advance on the back surface of the seal lid 2 (on the storage unit 15 side). By providing such an elastic layer, the foam sheet 5 is sandwiched between the mesh net 4 and the elastic layer in a slightly compressed state. When the seal lid 2 is opened, air flows into the storage unit 15 from the outside, but the foam sheet 5 released from the pressure by the mesh net 4 and the elastic layer expands while sucking in the nearby air and powder cosmetics. Therefore, scattering of the cosmetics outside the container can be effectively prevented.
