By my present invention I have sought to sim suitable for union with the top l2. The outside I 3 may also be of the same composition. I have found that material such as a cellulose acetate composition which is capable of being molded and also capable of being formed as a _ thin ?lm is especially adapted to my purpose. A. commercial molded composition known as “lumarith” and a ?lm known as “protectoid” may plify the method and reduce the cost of con struction. Another object is to provide a type 10 be used as examples of the type or class of ma terials capable of being united by the use of a of construction which is capable of reducing mois solvent such as acetone'or mono methyl ether ture loss of the contents to a minimum. of ethylene glycol or a combination of the two. In carrying out the invention I provide a body A commercial form of solvent is known as “methyl portion and an outlet or top and in effect secure them together autogenously. The bodyv consists 15 cellosolve.” . Another commercial product suitable for mold ing is known as “tenite.” The corresponding ?lm material is known as “kotopac.” A similar sol of laminations of metallic foil and non-metallic ?lm and the top is formed of a molded composi tion similar to the composition of the ?lm. The vent may be used. ‘ top has a groove with inner and outer walls to I have also found that the top may be formed which the inner and outer surfaces of the mouth 20 of a material such as a vinyl resin compound as of the body are secured. The body and top are l for example “Bakelite polystyrene” and the body united by applying to the parts to be united a surface of a ?lm of substantially the same sub chemical capable of dissolving or softening the stance. In that case the solvent may be ethyl surface of the material of the top and of the ?lm acetate. so that they cohere without substantial change 25 The top is provided with ‘a cylindrical or other of structure when the solvent evaporates.
