Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a cosmetic package, and more specifically, filling the recess with the cosmetic without adhering the cosmetic to the seal portion around the recess, and filling the cosmetic efficiently at high speed. The present invention relates to a method for producing a cosmetic package that can produce a package.

[0002]

2. Description of the Related Art Conventionally, as a simple packaging method for cosmetics, a method has been employed in which the cosmetics are partially adhered to a sheet and further covered with a cover sheet to seal the cosmetics. As a method for attaching a cosmetic product to a sheet in a pattern, a partial adhesive filling method mainly using screen printing is used. However, the method that uses screen printing cannot be performed at a very high speed.
Since the cosmetic to be adhered and filled scatters on the seal part around the adhered part and stains the seal part, there are drawbacks that the seal by the cover film is not sufficiently performed and the appearance is poor. Therefore, in order to adhere and fill the cosmetics to the sheet, a very careful operation is required in the low speed filling.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks of the prior art, and does not require a special careful operation when filling a container with cosmetics, and the filling is performed at high speed. Even if the seal portion is not contaminated, it can be filled and a sufficient seal can be provided, which provides an efficient method for producing a cosmetic package.

[0004]

Means for Solving the Problems As a result of intensive studies to solve the above problems, the inventors of the present invention focused on protecting the seal portion around the cosmetic filling portion when filling cosmetics. As a result of further diligent research, it was found that a recess for filling cosmetics should be partially provided in the sheet, and that the sealing part around the cosmetic filling part should be covered with a protective sheet when filling the cosmetic. By removing the protective sheet after filling, and further covering with a cover film and sealing, it was found that the above problems can be solved,
The present invention has been completed based on the findings.

That is, according to the present invention, the cosmetic is filled in the concave portion of the sheet in which the concave portion is partially provided with the seal portion around the concave portion covered with the protective sheet, and then the protective sheet is peeled off. Then, the present invention provides a method for producing a cosmetic package, which comprises covering the recess and the seal with a cover film to seal the recess. Hereinafter, the present invention will be described in detail.

In the present invention, a sheet partially provided with a recess is used. The number of recesses partially provided in the sheet may be one, or may be two or more.

The thickness of the protective sheet is usually 10 to 200 μm, preferably 20 to 200 μm.
The thickness is 80 μm.

When the protective sheet has adhesiveness to the seal portion on the sheet surface, it is not necessary to provide an adhesive layer between the protective sheet and the seal portion on the sheet surface, but it is preferable to provide an adhesive layer. Further, even when the above-mentioned protective sheet does not have adhesiveness to the seal portion on the sheet surface, it is preferable to provide an adhesive layer. When the adhesive layer is provided, the seal portion can be completely protected by the protective sheet. In particular, the seal portion is preferably covered with a protective sheet via a double-sided adhesive film, and the pressure-sensitive adhesive layer on the sheet surface side of the double-sided adhesive film is a re-peelable pressure-sensitive adhesive layer. Most preferably, the pressure-sensitive adhesive layer on the side is composed of a strong pressure-sensitive adhesive layer.

When the protective sheet is provided via the double-sided adhesive film having different adhesive strength, the protective sheet is preferably a release paper or a sheet having a release ability equivalent to that of the release paper. A sheet that can be easily peeled from the pressure-sensitive adhesive layer, such as a release sheet, is in close contact with the sheet via the removable pressure-sensitive adhesive layer, even though it is in contact with the strong pressure-sensitive adhesive layer. The double-sided pressure-sensitive adhesive film can be peeled from the strong pressure-sensitive adhesive layer without being peeled from the sheet.

The adhesive force of the removable adhesive is preferably half or less than the adhesive force of the strong adhesive, and particularly 3
An adhesive strength of 0% or less is preferable. This allows the double-sided adhesive film to be peeled off from the seal part of the sheet while being in close contact with the cover film when the cover film is peeled off and the cosmetic product is taken out.

For example, the above-mentioned pressure-sensitive adhesive may be dissolved in a suitable solvent and applied, or dispersed in a suitable medium. Examples thereof include a method of emulsifying and coating, a method of coating without solvent or a method of coating with a calendar roll.

Next, a preferred embodiment of the method for producing the cosmetic package of the present invention will be described. A preferred embodiment consists of the following steps. (1) A step of bonding a continuous long core sheet and a continuous long protective sheet (2) A step of forming a hole for forming a recess in a laminated sheet in which the core sheet and the protective sheet are bonded 3) Next, a step of laminating a perforated laminated sheet and a continuous long bottom sheet to form a concave portion (4) A step of filling the formed concave portion with cosmetics (5) A step of peeling a protective sheet (5) 6) A step of covering the recess filled with the cosmetic and the seal with a continuous long cover film to seal the recess (7) Whether to cut or wind the sheet having the sealed recess into an appropriate size Or the step of slitting

In the step (1), a continuous long core sheet and a continuous long protective sheet are continuously supplied, and the supplied core sheet and protective sheet are bonded together to form a laminated sheet. To form. Here, in the present invention, continuous does not only mean continuous in a narrow sense,
It also includes the meaning of intermittent. When sticking the core sheet and the protective sheet, it is preferable to provide a pressure-sensitive adhesive layer between the core sheet and the protective sheet to completely adhere the core sheet and the protective sheet. If the adhesiveness is good, the pressure-sensitive adhesive layer may not be provided.
The method of providing the pressure-sensitive adhesive layer can be performed by various methods, and may be provided at the same time as the bonding of the core sheet and the protective sheet, or the surface of the protective sheet to be bonded to the core material sheet in advance may be the pressure-sensitive adhesive layer. It may be covered with. Further, the surface of the core material sheet to be attached to the protective sheet may be coated with an adhesive in advance.

Further, the adhesive force of the core material sheet to the adhesive layer is preferably larger than the adhesive force of the protective sheet to the adhesive layer. This allows the protective sheet to be easily peeled from the pressure-sensitive adhesive layer after filling the recess with the cosmetic. Further, as described above, the seal portion is preferably covered with a protective sheet via a double-sided adhesive film, and the adhesive on the sheet surface side of the double-sided adhesive film is a re-peelable adhesive, It is most preferable that the pressure-sensitive adhesive on the protective sheet side is composed of a strong pressure-sensitive adhesive.

In the step (2), a hole for forming a recess is formed in the laminated sheet laminated in the step (1). Various methods can be used for making the holes, but a method of punching with a punching blade having a concave planar shape is preferable. The punching is continuously performed at predetermined intervals in the continuously supplied laminated sheets. The positions of the holes may be appropriately selected according to the width of the laminated sheet and the size of the holes, and the number of holes may be one in the width direction of the laminated sheet or may be two or more.

In the step (3), the laminated sheet perforated in the step (2) and the continuous long bottom sheet are bonded together to form a recess. The laminated sheet in which the long core sheet and the long bottom sheet are bonded together corresponds to the sheet of the present invention. The core sheet and the bottom sheet are preferably made of the same material. Further, in order to improve the adhesiveness between the laminated sheet and the bottom sheet, it is preferable to provide an adhesive layer. The method for providing the pressure-sensitive adhesive layer can be carried out by various methods, and it may be provided at the same time as laminating the laminated sheet and the bottom sheet, or the surface of the laminated sheet previously laminated to the bottom sheet is covered with the pressure-sensitive adhesive layer. The surface of the bottom sheet to be laminated to the laminated sheet may be coated with the pressure-sensitive adhesive layer in advance, but it is preferable not to provide the pressure-sensitive adhesive layer on the surface of the bottom sheet which is the bottom of the hole. The thickness of the bottom sheet is usually 10 to 500 μm, and preferably 25 to 200 μm.

In the above step (4), the concave portion formed in the step (3) is filled with cosmetics.
Various means can be adopted, and one recess may be continuously filled, or a plurality of recesses may be simultaneously filled continuously. In this step, even if the cosmetic is filled at high speed, the cosmetic may adhere to the protective sheet but not to the seal portion, so that the cosmetic can be filled at high speed.

In the step (5), the protective sheet is peeled off from the laminated sheet. When an adhesive layer is provided between the protective sheet and the core sheet, when the protective sheet is peeled from the laminated sheet, the adhesive layer may be peeled off together with the protective sheet without leaving the adhesive layer on the core sheet surface. You may peel off only the protective sheet while leaving the agent layer on the surface of the core material sheet, but the latter can effectively use the adhesive layer and can cover the recess by simply covering the recess with the cover film in the next step. In addition, since the inner surface of the cover film in the recess has no adhesive layer, it is possible to make it difficult to change the quality of the cosmetic product, which is preferable.

In the step (6), the recess filled with the cosmetic product and the seal are covered with a continuous long cover film to seal the recess. When the pressure-sensitive adhesive layer is provided between the cover film and the laminated sheet, the seal portion can be sealed with the cover film only by pressing the cover film and the laminated sheet via the pressure-sensitive adhesive layer. The method of providing the pressure-sensitive adhesive layer can be performed by various methods,
It may be provided at the same time as laminating the laminated sheet and the cover film, or the surface of the laminated sheet to be laminated to the cover film in advance may be covered with an adhesive layer,
Although the surface of the bottom sheet which is laminated to the laminated sheet in advance may be covered with the pressure-sensitive adhesive layer, it is preferable not to provide the pressure-sensitive adhesive layer on the inner surface of the cover film covering the recess.
As the thickness of the cover film, the thickness described above can be used.

In the above step (7), the sheet having the recesses filled with the cosmetic is cut into an appropriate size, wound up, or when there are a plurality of recesses in the width direction of the sheet, an appropriate width is obtained. Make a slit in the longitudinal direction. Through the above steps, the cosmetic packaging body is continuously manufactured. The method of manufacturing a cosmetic package according to the above steps, a core sheet, a bottom sheet,
A long continuous sheet is used as the protective sheet and the cover film, and since these films are continuously supplied, it is possible to continuously manufacture a cosmetic package.
It is possible to manufacture a cosmetic package extremely efficiently.

A step of matting the bottom sheet may be added between the steps (3) and (4). However, if a matte-treated material is used as the raw material of the bottom sheet, it is not necessary to add a step for matte treatment. It is preferable to apply unevenness treatment to the inner bottom of the recess like matte treatment, because when the cosmetics, especially powder cosmetics such as eye shadows, are filled, the cosmetics easily adhere to the bottom and are less likely to adhere to the cover film. . Further, it is possible to deepen the recess by inserting embossing between the steps (3) and (4). However, if the recess is made too deep by embossing, the workability of manufacturing the cosmetic package will be somewhat deteriorated. Further, it is possible to perform printing on the front surface or hot stamping before or after any of the above steps or before or after any of the above steps, or to perform similar processing on the back surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be specifically described with reference to the drawings based on embodiments. However, the present invention is not limited to these examples.

Example 1 FIG. 1 is a schematic cross-sectional view showing a method for manufacturing a cosmetics package, which is an example of the present invention. In FIG. 1, width 200
mm, 50 μm thick release sheet provided with a pressure-sensitive adhesive layer (coating thickness: 5 μm) made of a releasable pressure-sensitive adhesive containing a rubber-based resin as a main component on one side of a long protective sheet wound into a roll. The protective sheet 4 with the pressure-sensitive adhesive layer was continuously supplied from the original protective sheet roll 3. On the other hand, width 2
One side of a long core sheet made of polyethylene terephthalate having a thickness of 00 mm and a thickness of 300 μm, and an adhesive layer made of an adhesive containing an acrylic resin as a main component (coating thickness: 25 μ
m) is provided, and a release sheet is temporarily attached and wound in a roll shape.
Was continuously fed. Continuously supplied protective sheet 4
The core material sheet 2 was superposed on the pressure-sensitive adhesive layer surface provided on the protective sheet 4 and the core material sheet surface not provided with the pressure-sensitive adhesive layer.

Then, the laminated laminated sheets were passed through a pair of rolls 13 and pressure-bonded to each other to bond them together. The adhesive strength between the release sheet and the adhesive layer is 50 g / 25 mm, and the adhesive strength between the core sheet and the adhesive layer is 200 g.
It was / 25 mm. Next, a punching blade having a concave planar shape is intermittently driven and intermittently pressed against a continuously supplied laminated sheet to form a concave 2
Punch a circular hole of cm, and 1c in the feeding direction of the laminated sheet.
Holes were intermittently formed at intervals of m. The release paper temporarily attached to the core sheet was removed.

Next, the bottom sheet 7 is continuous from the bottom sheet raw roll 6 in which a long bottom sheet 7 having a width of 200 mm and a thickness of 50 μm and made of polyethylene terephthalate having a matte surface on one side is wound in a roll shape. Supplied. The supplied bottom sheet 7 is superposed on the pressure-sensitive adhesive layer provided on the core material sheet, and is pressed and bonded through a pair of rolls 14 to partially form a concave portion having an inner bottom matted on the sheet. Formed. Then, the eye shadow filling machine 8 was intermittently driven to fill the eye shadows in the recesses provided intermittently at predetermined intervals in the continuously supplied laminated sheets.

Next, the protective sheet 4 made of a release sheet
Was peeled off, leaving the pressure-sensitive adhesive layer on the surface of the core sheet, and wound on a roll 9. Furthermore, width 200mm, thickness 50μ
A cover film original roll 10 in which a long cover film 11 made of polyethylene terephthalate containing 0.1% by weight of a benzophenone-based ultraviolet absorber is wound in a roll shape. From the above, the cover film 11 was continuously supplied to cover the sealing portion and the concave portion of the laminated sheet with the corona discharge treated surface inside.

Next, the laminated sheet covered with the cover film 11 was passed between a pair of rolls 15 and pressure-bonded, the seal portion was sealed with the cover film 11, and the recess was sealed. The adhesive strength between the cover film 11 and the adhesive layer is 3
It was 00 kg / 25 mm. Finally, the cutting blade 12 was intermittently driven and pressed against the continuously fed sheets, and the sheets were cut at appropriate intervals to manufacture a cosmetic package. Since there is no adhesive layer on both the inner bottom of the recess and the inner surface of the cover film 11, there was almost no deterioration of the eye shadow.

The outline of the partial cross-sectional view of the recess of the obtained cosmetic package is shown in FIG. An eye shadow 22 is filled in the concave portion 21, and a core portion sheet 2 and a cover film 11 are bonded to each other via a re-peelable pressure-sensitive adhesive layer 23 in a sealing portion to form a bottom of the concave portion 21. There is no adhesive layer inside the bottom sheet, and there is no adhesive layer on the inner surface of the cover film 11 that covers the upper portion of the recess 21. When the cover film 11 of the obtained cosmetic package was peeled off, the adhesive strength between the cover film 11 and the removable pressure-sensitive adhesive layer 23 was larger than the adhesive strength between the core sheet 2 and the removable pressure-sensitive adhesive layer 23. Therefore, the removable pressure-sensitive adhesive layer 23 was peeled off while being attached to the cover film 11, and the removable pressure-sensitive adhesive layer 23 did not remain on the surface of the sheet.

Example 2 In Example 1, polyethylene terephthalate having the same width and thickness was used in place of the release sheet, and a cover film provided with an adhesive layer on one surface was used instead of the cover film continuously supplied. A cosmetics package was manufactured in the same manner as in Example 1 except that it was used. When the protective sheet is peeled off from the laminated sheet, the pressure-sensitive adhesive layer is peeled off while being adhered to the protective sheet, and a cover having a pressure-sensitive adhesive layer provided on one side in a state where the pressure-sensitive adhesive layer is not provided on the sheet surface. The pressure-sensitive adhesive layer surface of the film was placed inside and laminated. The outline of the partial cross-sectional view of the recess of the obtained cosmetic package is shown in FIG. In the obtained cosmetic package, since the inner surface of the cover film 11 that seals the upper part of the recess has the removable pressure-sensitive adhesive layer 23, eye shadow easily adheres to the removable pressure-sensitive adhesive layer. , Eye shadow was slightly attached.

Example 3 The procedure of Example 1 was repeated, except that a release sheet having a double-sided adhesive film on one side was used instead of the release sheet having an adhesive layer on one side. The outline of the partial cross-sectional view of the recess of the obtained cosmetic package is shown in FIG. This double-sided adhesive film has a base film 25 with a width of 2
It is made of polyethylene terephthalate resin having a thickness of 00 mm and a thickness of 50 μm, and has a strong adhesion type pressure-sensitive adhesive layer 26 (coating thickness: 25 μm) containing an acrylic resin as a main component on the contact surface with the release sheet, and the other surface. A removable adhesive layer 24 (coating thickness: 2
5 μm).

The release sheet and the strong adhesive type adhesive layer 26
The adhesive strength between the sheet and the removable pressure-sensitive adhesive layer 24 is 100 g / 25 m.
m. Therefore, when the protective sheet 4 was peeled off after the core material sheet 2 and the protective sheet 4 were bonded together, only the release sheet was peeled off while the double-sided adhesive film was still attached to the sheet as in Example 1. In addition, the cover film 11 has the recess 2
The adhesive strength between the cover film 11 and the strong adhesive type pressure-sensitive adhesive layer 26 when covering 1 and the seal portion with the seal portion was 1500 g / 25 mm, and the cosmetic product obtained in the same manner as in Example 1 When the cover film 11 of the package was peeled off, the cover film 11 and the strong adhesive pressure-sensitive adhesive layer 26 were removed.
Since the adhesive strength between the core material sheet 2 and the removable pressure-sensitive adhesive layer 24 is larger than that of the core material sheet 2, the double-sided adhesive film is peeled off while being attached to the cover film, and the surface of the core material sheet 2 is removable. The adhesive layer 24 did not remain.

[0045]

According to the method for manufacturing a cosmetic package of the present invention, when the cosmetic is filled in the concave portion, the seal portion around the concave portion is covered and protected by the protective sheet, so that the cosmetic adheres to the seal portion. Even without using the high-speed filling means that easily scatters around the concave portion when filling the cosmetics, the seal can be completely sealed by the cover film to cleanly seal the concave portion.
