DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic laminate having a water absorbing function and a paper box which can be used for chilled distribution of home delivery.

[0002]

2. Description of the Related Art Conventionally, for chilled distribution of home delivery, containers made of styrene foam which has a high cooling effect and is resistant to generation of moisture such as dew condensation have been used. However, containers made of styrofoam have the above-mentioned characteristics, but due to their large bulk, problems such as dust at the time of disposal and high calories burned during combustion have come to be regarded as problems. Examples of the container having a water absorbing function include, for example, Japanese Utility Model Publication No. 58-4229.
As described in No. 5, a food storage container having a configuration in which a liquid storage recess is formed in the bottom inner surface of a dish-shaped container body formed of a water-resistant material and a water-absorbing mat is laid inside the recess. As is known, in the case of this container, since the water-absorbent mat is made from an organic polymer substance having a property of swelling by water absorption to form an aqueous gel, the production of the water-absorbent mat is complicated. At the same time, the work efficiency of the step of forming a liquid storage recess on the inner surface of the bottom of the dish-shaped container body and the step of laying a water-absorbing mat is poor, resulting in an expensive container and poor surface design and poor water resistance. There is a disadvantage that.
Further, a water-insoluble, water-absorbing and water-holding resin powder alone or partially porous with a water-soluble resin on the inner surface of a container, or a resin and a porous resin, as described in JP-A-58-126986. Although there is a container having a water-absorbing and water-retaining resin layer composed of any of a mixture with an inorganic powder, in the case of this container, the step of applying the water-absorbing and water-retaining resin layer to the container base surface is complicated. For this reason, there are drawbacks in that it is expensive and the surface design and water resistance are not excellent. Furthermore, as described in JP-A-61-11345, for packaging, a water-impermeable layer is formed on the bottom surface of a box, and a water-gelling layer and a water-absorbing diffusion layer covering the water-gelling layer are disposed thereon. Although a box is known, the step of forming a moisture gelling layer on the bottom surface of a packaging box is complicated, and the number of steps of providing a water-absorbing diffusion layer on the moisture gelling layer increases, so the box is expensive and the surface is expensive. However, there is a drawback that the water resistance and design properties of these are not excellent.
