  FIG. 3 is a diagram schematically showing a cross section taken along line XX in FIG. 2, and the blank plate 10 is formed from the outside toward the inside, for example, the base material layer 20 composed of the LDPE layer 20 b and the paper layer 20 a, A configuration in which an adhesive layer 23, an intermediate layer 21 made of a gas barrier layer, an adhesive layer 24, and an inner layer 22 made of a linear low density polyethylene layer (hereinafter referred to as LLDPE) as a heat-adhesive resin layer are laminated in order. The intermediate layer 21 has a nylon film 210 and a polyester film 212 having a vapor-deposited layer 212a made of metal or metal oxide on one side. The vapor-deposited layer 212a is positioned on the nylon film 210 side through the adhesive layer 211. It is the structure laminated | stacked so. As is clear from FIG. 3, the notch 12 is a window formed through the base material layer 20 including the outer LDPE layer 20 b and the paper layer 20 a, and the notch portion 12 of the base material layer 20 has the LDPE layer 20 b. On the outside, a surface layer 26 made of a polyethylene resin layer is laminated on the entire outer surface of the LDPE layer 20 b of the base material layer 20 so as to cover the notch 12. In the cutout portion 12 that is a window, the surface layer 26 made of a polyethylene resin layer and the adhesive layer 23 are directly laminated, and the peripheral edge of the cutout portion 12 is covered with the surface layer 26. Is configured not to be exposed.

The base material layer 20 constituting the laminate 25 may be only the paper layer 20a. However, when printing is performed on the outer surface of the base material layer 20, the base material layer 20 includes the LDPE layer 20b on the paper layer 20a. Since the layers are laminated and the surface of the LDPE layer 20 is printed, the printability is improved, which is more preferable. Also, the paper used in paper layer 20a is usually ^{200g / m 2 ~480g / m 2} .
As the intermediate layer 21 composed of a gas barrier layer, the basic structure is a structure in which a nylon film 210 and a polyester film 212 are laminated via an adhesive layer 211. Further, when gas barrier properties are required, It can also be replaced with a nylon film having a deposited layer on which a metal or metal oxide is deposited or a polyester film having a deposited layer on which a metal or metal oxide is deposited. When a higher gas barrier property is required, the nylon film 210 can be replaced with a nylon film having the vapor-deposited layer or the polyester film 212 to be a polyester film having the vapor-deposited layer. When a better gas barrier property is required, a configuration in which a nylon film having the vapor deposition layer and a polyester film having the vapor deposition layer are laminated is adopted. The nylon film and the polyester film are preferably a biaxially stretched nylon film (hereinafter referred to as “ON”) and a biaxially stretched polyester film (PET), and a vapor deposition layer deposited on these films is a metal such as aluminum or aluminum oxide. A layer on which an inorganic material such as silicon oxide is deposited is preferable.

Is preferred. Moreover, it is preferable to perform adhesion auxiliary treatment such as corona discharge treatment, ozone treatment, and anchor coat treatment on the surface of the paper layer 20a constituting the base material layer 20 facing the adhesion layer 23, even if repeated squeeze operations are performed. There is an effect of preventing separation between the paper layer 20 a and the adhesive layer 23 at the notch 12.
As the polyethylene resin layer constituting the surface layer 26, resins such as LDPE, MDPE, HDPE, and LLDPE can be used. However, when the surface layers are thermally bonded to each other, the low-temperature sealability and adhesion to the adhesive layer 23 at the notch 12 are possible. Considering the properties, LDPE and LLDPE are preferable.
The adhesive layers 23 and 24 are layers that serve as an adhesive layer for laminating the base material layer 20, the intermediate layer 21, and the inner layer 22. The adhesive layers 23 and 24 include LDPE, an ethylene-methacrylic acid copolymer. (Hereinafter referred to as EMAA), an ethylene-acrylic acid copolymer (hereinafter referred to as EAA) can be used. Note that an LDPE layer may be laminated in advance on the surface of the intermediate layer 21 facing the adhesive layer 23. By doing so, it is possible to use an LDPE resin that is inexpensive and excellent in extruding workability for the adhesive layer 23, and that the laminated body becomes a multilayer and each layer is laminated (a combination of layers and layers to be laminated). The order in which the layers are combined) varies widely, but the order of stacking shown in the examples described later can be adopted, and the order of stacking with high productivity becomes preferable.
The adhesive layer 211 is a layer in which a nylon film and a polyester film constituting the intermediate layer 21 are laminated. For example, the adhesive layer 211 is a two-component curable general-purpose dry laminate adhesive having a polyester polyol as a main component and an isocyanate as a curing agent. In particular, when using a vapor-deposited nylon film or vapor-deposited polyester film, or vapor-deposited nylon film and vapor-deposited polyester film, it is preferable to laminate with a dry laminate adhesive by a dry lamination method because a strong adhesion can be obtained.

Next, a preferred configuration example of the laminate used in the gobbel top type paper container of the present invention is illustrated.
