An easily breakable plastic capsule according to the present invention comprises a hollow cylindrical body capable of elastic deformation. The body is packed with a fluid material. An end wall of the body is formed with a plurality of radially extending grooves. When the body is deformed elastically, the bottom walls of the grooves are broken, so that the material flows out of the body through tears in the grooves. A water filter according to the present invention comprises a casing, made of paper and coupled to a cigarette, and a filter member and the capsule arranged in the casing. The grooved end wall of the capsule is situated in close vicinity to the filter member.

A decorative laminated structure having on its surface a pattern composed of concaves and convexes which are formed by local heat shrinkages of a layer of a heat-shrinkable resin sheet employed. Such decorative laminated structure can be obtained by laying a base, a heat-shrinkable resin sheet and a picture layer containing at least a plurality of heat sensitive picture areas in a predetermined order to form a composite material, said heat sensitive picture areas being contiguous and closely adherent to said heat-shrinkable resin sheet; and irradiating the resulting composite material with a heat ray to cause said heat-shrinkable resin sheet at its portions corresponding to said heat sensitive picture areas to cave in, thus forming concaves. The present decorative laminated structure has, alone or in combination with the other structures, a wide variety of uses, for example, not only as a material for a ceiling, a floor, a wall and/or an interior decoration of a building, car, ship and the like but also as a decorative material for furnitures, fittings, tables, musical instruments, cabinets and the like.

This invention provides a decorative laminated structure having on the surface a pattern composed of concaves, at least one of said concaves having an opening at its bottom portion formed by local heat shrinkage of a layer of a heat-shrinkable resin sheet employed. Such decorative laminated structure is prepared by a method comprising forming a composite layer structure including a base, a heat-shrinkable resin sheet, a picture layer containing heat insensitive picture areas and another picture layer having heat sensitive picture areas, said heat sensitive picture areas being contiguous and closely adherent to said heat-shrinkable resin sheet; and irradiating the composite layer structure with a heat ray in an amount sufficient for making an opening in the heat-shrinkable resin sheet to thereby cause the heat-shrinkable resin sheet to shrink locally and form concaves, at least one of said concaves having an opening at its bottom portion at portions corresponding to the heat sensitive picture areas. Such structure can also be prepared when a composite layer structure including a picture layer containing heat sensitive picture areas, said heat sensitive picture areas being contiguous and closely adherent to said heat-shrinkable resin sheet, is at first prepared in the same manner as above and irradiated with a heat ray and a picture layer having heat insensitive picture areas is applied on a heat-shrinkable resin sheet of the resulting composite layer structure. Such decorative laminated structure can be improved in thermal characteristics when it is subjected to a heat fixation treatment at elevated temperatures while fixing its peripheral ends. A decorative laminated structure of this invention exhibits excellent decorative effects, and can be used effectively as a decorating material in various fields.
