Abstract

PROBLEM TO BE SOLVED: To obtain a packing material with reduced discoloration by light which does not cause collapse of soaps contained in holes by blending a UV absorber with a flexible urethane foam during preparation or impregnating the flexible urethane foam with the UV absorber after preparation and by boring the flexible urethane foam by presswork to make holes fit for the outer form of soaps. SOLUTION: This flexible urethane foam is prepared from a polyol, an isocyanate, water, a catalyst, a foam stabilizer and other auxiliaries. The softness of the flexible urethane foam is 17±5 kgf. The flexible urethane foam is preferably immersed in a binder containing a UV absorber to impregnate the flexible urethane foam with the UV absorber. As the binder, for example, a urethane resin-based binder is used. The UV absorber is preferably present in 0.2-2 mg/cm3 with reference to the foam. As the UV absorber, for example, benzotriazole-based and benzophenone-based compounds are used.

2. Description of the Related Art A usual packing material of soap uses cardboard or other cardboard, and a packing material in which a corrugated cardboard plate is combined in a grid pattern on the left and right to form a recess for storing soap is used. However, since this packing material is made of paper and has a simple pattern, it does not have a very good appearance. In a department store or the like, the cardboard packing material is not opened for display.

[0003] In addition, the soap packed in the cardboard packing material is dislodged or rotated when the soap stored in the packing material is transported or displayed at a store. It is not preferable because it collapses. Soap packaging materials have been proposed in which a soft polyurethane foam sheet is used to remedy this drawback, holes and holes are made in the sheet according to the outer shape of the soap, and soap is fitted into the holes. A packing method is adopted in which the sheet is fitted into the hollow without being wrapped.

A soap is fitted into the hole of the packing material,
When this was given the same inclination and vibration as during transportation, the soap moved and a gap was formed in the foam 2, but such a defect did not occur in the packing material of the foam 1. In addition, since these foam materials do not contain an ultraviolet absorbing material, yellowing due to light cannot be avoided.
