As shown in the figure, a light-shielding layer (41) made of a pattern-printed ink layer is formed on the inner surface of a paper substrate (11) having a polyolefin-based resin (10) as an outermost layer. The light-shielding layer of the ink layer is concealed by laminating the white polyolefin resin (60). Alternatively, it is also possible to provide printing on the outside of the barrier film (12) instead of the paper substrate as the light-shielding layer to impart light-shielding properties. In both cases, the paper substrate (11) and the barrier film (12) may be bonded with a resin such as polyethylene, or may be bonded using an adhesive or the like. At this time, if the light-shielding layer (41) is printed in a pattern in which the printed portion is not provided around the blank shape as shown in FIG. 6 and the printed portion is made smaller, the ink is not exposed on the end surface (2), and the ink surface is reduced. Direct contact with the contents at the end face (2) can be prevented.

As shown in FIG. 4A, the polyolefin resin (1
0) as the outermost layer, a paper substrate (11) and a barrier film (12), and an adhesive light-shielding layer (42) having light-shielding properties;
The adhesive light-shielding layer (42) is attached, and the inner surface is concealed with a concealing layer made of a white polyolefin-based resin (60). When the outermost layer is the same resin as the white polyolefin-based resin (60), the white polyolefin-based resin (60) may be used as the innermost layer. Also,
To improve the sealability and make the moldability even better,
As shown in FIG. 4B, a sealant layer (13) may be provided. Here, the light-shielding adhesive is obtained by mixing a pigment such as carbon black into an adhesive used for dry bonding of a film, paper, or the like. The coating amount is 2 g / m
A range from 2 to 8 g / m 2 is appropriate. The method of providing the adhesive with a light-shielding property is easier to cope with in a relatively small lot than the method of coloring the resin. This is because, when coloring a resin, it is necessary to purge a large amount when replacing a particularly colored resin in a melt extruder, and a large amount of material and time are required, which is not suitable for small-quantity production.

A configuration in which a concealing layer is formed on the outer surface of (12) by printing other than black ink may be used.

It is sectional drawing of the sheet | seat which formed the sealant in the lamination innermost layer. As shown in FIG. 5 (b), the light-shielding method may be such that a light-shielding layer (41) made of an ink layer printed in a pattern on the inner surface of the paper substrate (11) may be formed.
In both cases, the method of bonding the paper, which is the concealing layer (62), and the barrier film (12) may be such that the paper substrate (11) and the barrier film (12) are bonded by a resin such as polyethylene, The bonding may be performed using an adhesive or the like.

性に問題が発生する。Since the paper base material (11) in the above configuration is further bonded to the paper as a concealing layer, it is preferable to make the thickness of the paper thinner than usual. The basis weight of the paper is 100 g /
m 2 to 300 g / m 2 are preferred. Paper is a hiding layer may, basis weight, good 100g / m 2 ~300g / m 2 . If it is too thin, there is no hiding effect, and if it is too thick, there is a problem in the moldability of the cup.

It is almost the same as a three-layer paper cup and does not look inferior.
