Definitions

  • the present invention relates to a package.
  • packages for packaging articles to be packaged.
  • articles to be packaged are, for example, cigarettes such as paper rolled tobacco sticks or cigars, every predetermined number of cigarettes, for example, 10 or 20, are wrapped in a package.
  • a package is composed of, for example, an inner paper such as a paper processed with an aluminum foil, and an outer paper covering the inner paper.
  • the outer paper are a package called a soft package made of a thin paper, and a package called a hard package formed by assembling paperboard into a box shape (see, for example, PTL 1 and PTL 2).
  • a surface of a sheet material which forms a part of the package is conventionally laminated with metallic aluminum (aluminum).
  • metallic aluminum aluminum
  • an aluminum lamination method and an aluminum vapor deposition method are conventionally known.
  • an aluminum lamination method an aluminum layer is formed on a surface of a sheet material by bonding an aluminum foil to the surface of the sheet material through an adhesive agent.
  • an aluminum particle layer and a PET layer are formed on a surface of a sheet material by bonding a PET (polyethylene terephthalate) film on which aluminum was deposited to the surface of the sheet material through an adhesive agent.
  • the thickness of an aluminum layer formed on the surface of the sheet material corresponds to the thickness of the aluminum foil.
  • the thickness of the aluminum foil is thicker than the thickness of an aluminum particle layer which is formed by vapor deposition of aluminum.
  • the PET layer may elongate and may not be completely cut. Thus, there is the problem that processing is difficult.
  • the present invention has been made in view of the above problems, and one of the objects of the invention is to provide a package including a lustrous part with excellent processability.
  • a package for internally containing cigarettes includes a lustrous part having metallic luster.
  • the lustrous part includes: a sheet layer made of paper, an aluminum particle layer arranged above the sheet layer; an adhesive layer positioned between the sheet layer and the aluminum particle layer and configured to bond the aluminum particle layer to the sheet layer; and a protective layer arranged above the aluminum particle layer, and the aluminum particle layer is a transferred vapor-deposited aluminum particle layer.
  • the package has the transferred vapor-deposited aluminum particle layer above the sheet layer.
  • the aluminum particles are sparser compared to an aluminum foil. Therefore, the aluminum layer to be deposited in this description is different from an aluminum layer formed by bonding an aluminum foil, and is called the "aluminum particle layer".
  • the thickness of the transferred vapor-deposited aluminum particle layer is very thin compared to an aluminum layer formed by the aluminum lamination method.
  • the density of the aluminum particles in the transferred vapor-deposited aluminum particle layer is also much lower compared to the density of the aluminum particles in the aluminum layer formed by the aluminum lamination method. More specifically, an aluminum foil to be used in the aluminum lamination method is formed by thinly stretching metallic aluminum, and thus the aluminum particles are densely arranged.
  • the aluminum particle layer formed by transfer of vapor-deposited aluminum has a larger space between the aluminum particles compared to the aluminum foil. Therefore, the transferred vapor-deposited aluminum particle layer is less susceptible to surface cracking when the folding process is performed on the lustrous part, and separation from the sheet layer is less likely to occur when the punching process is performed.
  • the lustrous part since the lustrous part has the transferred vapor-deposited aluminum particle layer with a thin thickness and does not have a PET film for vapor-deposited aluminum, the sheet stiffness is almost the same as that of an unprocessed sheet material, and the lustrous part can have high processability close to that of the unprocessed sheet material.
  • the aluminum layer formed by the aluminum lamination method has a relatively high density between the aluminum particles, moisture permeability is lower compared to the transferred vapor-deposited aluminum particle layer. Accordingly, the difference between the amount of moisture entering the sheet material from a surface to which the aluminum foil is bonded and the amount of moisture entering the sheet material from a surface on the opposite side is relatively large. In this case, the difference in moisture content occurs in the thickness direction of the sheet material, and consequently warping of the sheet material may occur. When the warping of the sheet material occurs, it is difficult to supply a blank (material before being assembled into a package) to a packaging machine, or the assembly itself cannot be performed.
  • the moisture permeability of the transferred vapor-deposited aluminum particle layer is higher compared to the aluminum foil. Therefore, since the difference between the amount of moisture entering the sheet layer from a surface on which the transferred vapor-deposited aluminum particle layer is formed and the amount of moisture entering the sheet layer from a surface on the opposite side is small, it is possible to reduce occurrence of warping of the sheet layer.
  • a package for internally containing cigarettes includes a lustrous part having metallic luster.
  • the lustrous part includes: a sheet layer made of paper; an aluminum particle layer arranged above the sheet layer; an adhesive layer positioned between the sheet layer and the aluminum particle layer and configured to bond the aluminum particle layer to the sheet layer; and a protective layer arranged above the aluminum particle layer.
  • the total thickness of the aluminum particle layer, the adhesive layer and the protective layer is 0.005 mm or less.
  • the package has the adhesive layer, the aluminum particle layer and the protective layer above the sheet layer.
  • the total thickness of the aluminum particle layer, the adhesive layer and the protective layer is 0.005 mm or less, which is thinner compared to an aluminum layer formed by the aluminum lamination method.
  • the aluminum particle layer which enables the total thickness of the aluminum particle layer, the adhesive layer and the protective layer to be 0.005 mm or less can be formed by transfer of vapor-deposited aluminum.
  • the density of the aluminum particles in the aluminum particle layer is also much lower compared to the density of the aluminum particles in an aluminum layer formed by the aluminum lamination method.

  • the aluminum particles are densely arranged.

  • the sheet stiffness is almost the same as that of an unprocessed sheet material, and the lustrous part can have high processability close to that of the unprocessed sheet material.
  • the difference between the amount of moisture entering the sheet layer from a surface on which the aluminum particle layer is formed and the amount of moisture entering the sheet layer from a surface on the opposite side is small, it is possible to reduce warping of the sheet layer.
  • the protective layer contains a pigment.
  • Overcoat printing is performed on the aluminum layer formed on a surface of a sheet material formed by the aluminum lamination method in order to protect the surface during machining. Moreover, when adjusting the color tone of the surface, printing for color tone expression is performed. Therefore, when expressing a color tone on the surface of the aluminum layer, it is necessary to perform printing twice, namely printing for surface protection and printing for color tone expression, on the aluminum layer formed by the aluminum lamination method, and there is the problem that time and labor are required. According to this aspect, since the protective layer contains a pigment, the formation of the protective layer and the color tone expression process with the pigment can be performed simultaneously. In other words, since it is not necessary to perform overcoat printing and printing for color tone expression individually, it is possible to reduce man-hours and ink for printing.
  • the protective layer has a pattern formed by the pigment.
  • the protective layer since the protective layer has a pattern formed by the pigment on its surface, it is possible to give more design to the package.
  • the package includes: a package main body; a lid part for closing the package main body; and an inner frame provided inside the package main body.
  • the inner frame is configured such that at least a portion of the inner frame is exposed when the lid part is opened, and the lustrous part is the inner frame.
  • the inner frame has bright and lustrous looks because of the aluminum layer.
  • the bright and lustrous inner frame is exposed, and thus it is possible to give an excellent design and a luxurious look to the package.
  • the protective layer contains a pigment, in general, the surface protection ability tends to decrease.
  • the protective layer contains a pigment, it is possible to exhibit sufficient surface protection ability for a part which is relatively less susceptible to surface abrasion, such as the inner frame, during packaging by a packaging machine or during subsequent transportation. Accordingly, in the case where the inner frame is a lustrous part containing a pigment in the protective layer, a reduction in man-hours by simultaneously performing overcoat printing and printing for color tone expression and the surface protection ability can both be achieved.
  • the inner frame has a punched portion.
  • the thickness of the aluminum particle layer is thin.

  • the lustrous part can smoothly pass through the inside of a machine when machine-processing the lustrous part, and has good processability. If the smoothness is less than 500 seconds, the smoothness is too low to smoothly pass through the inside of the machine, and a paper jam may occur. On the other hand, if the smoothness exceeds 2000 seconds, the smoothness is too high and makes it difficult for the machine to grip the lustrous part during assembly, and thus there is a possibility of assembly failure.

  • the average value of the thickness of the aluminum laminated inner frame is 0.020 mm greater than the average value of the thickness of the unprocessed inner frame. This means that, in the aluminum lamination method, an aluminum foil bonded to the inner frame is thick.
  • the inner frame 30 having the aluminum particle layer 43 formed by transfer of vapor-deposited aluminum can be made thinner than the inner frame having the aluminum particle layer formed by other method. Therefore, the inner frame 30 has excellent processability, and cracking of the aluminum particle layer 43 in the folding process and separation of the aluminum particle layer 43 in the punching process are less likely to occur.
  • the average value of the stiffness of the processed surface of the transfer-vapor-deposition paper is 0.02 mN greater in the longitudinal direction and 0.37 mN greater in the transverse direction.
  • the average value of the stiffness of the unprocessed surface is 1.40 mN greater in the longitudinal direction and 1.02 mN greater in the transverse direction compared to the average values of the stiffness of the unprocessed paper. This indicates that the stiffness is increased by the process of transfer of vapor-deposited aluminum.
  • the aluminum layer formed by the aluminum lamination method is thicker than the aluminum particle layer formed by transfer of vapor-deposited aluminum. Therefore, paper having an aluminum layer formed by the aluminum lamination method (aluminum laminated paper) is presumed to have stiffness greater than the stiffness of the transfer-vapor-deposition paper. Paper having an aluminum particle layer formed by the aluminum vapor deposition method (aluminum-vapor-deposition paper) has a PET film, and accordingly the aluminum-vapor-deposition paper is presumed to have stiffness greater than the stiffness of the transfer-vapor-deposition paper.
  • the transfer-vapor-deposition paper has greater stiffness than the stiffness of the unprocessed paper, but has smaller stiffness than the stiffness of the aluminum laminated paper and the aluminum-vapor-deposition paper. Therefore, it is possible to easily perform the folding process and the punching process on the transfer-vapor-deposition paper compared to the aluminum laminated paper and the aluminum-vapor-deposition paper.
  • Example 3 one sheet of a test paper (transfer-vapor-deposition paper) formed by arranging an adhesive layer, an aluminum particle layer formed by transfer of vapor-deposited aluminum and a protective layer on a sheet material was produced, and smoothness was measured.
  • a test paper which was not processed (unprocessed paper) and one sheet of a test paper (vapor-deposition paper) having an aluminum particle layer formed by the aluminum vapor deposition method were produced, and the smoothness of each paper was measured.
  • the smoothness of paper is a value measured according to "JIS P 8119".
  • the measurement results are shown in Table 3.
  • the unit of the numerical values in Table 3 is seconds. Smoothness indicates that the greater the value, the higher the smoothness.
  • the smoothness of the surface of the transfer-vapor-deposition paper is greater than the smoothness of the unprocessed paper and is smaller than the smoothness of the vapor-deposition paper.
  • the transfer-vapor-deposition paper has improved smoothness compared to the unprocessed paper by having the adhesive layer, the aluminum particle layer and the protective layer. It is also indicated that there is a difference in smoothness between the vapor-deposition paper and the transfer-vapor-deposition paper because the vapor-deposition paper has a PET film layer between the aluminum particle layer and the protective layer in addition to the adhesive layer, the aluminum particle layer and the protective layer.
  • the transfer-vapor-deposition paper can smoothly pass through inside the machine and has good processability.
  • the smoothness and the stiffness of the vapor-deposition paper are increased by having the film, it is difficult to grip the vapor-deposition paper by the machine during assembly, and assembly failure may occur.
