BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to a disposable container which is designed to be thrown away after a single use.
DESCRIPTION OF THE PRIOR ART
In an automobile repair shop, for the purpose of coating a repaired portion on a car body with a paint of the same color as the immediately surrounding portion, for example, it becomes necessary to mix two or more paints in a mixing container to produce a paint of the desired color and coat the repaired portion with the mixed paint. Then, the container must be emptied of the unused paint and washed with a solvent such as a thinner to remove the portion of the paint still adhering to the container. The amount of the thinner used for the washing usually ranges roughly from 300 to 1000 cc and the time required by the worker for completing this task ranges from 10 to 30 minutes. This is troublesome work and jeoparidzes the worker's health because of the possibility of inhalation of thinner vapor.
Disposable cups used for drinking water have already acquired wide popularity. Those containers are shaped to forms befitting their respective intended applications and adapted to provide stability and ease of use, and they are generally expensive. Despite the great trouble of the work of washing as involved in the case of the mixing container used for the preparation of a paint as described above, many containers are still being used repeatedly between the steps of washing.
In consequence of a study continued on such problems of the conventional containers, the inventor became aware that the functions of containers, on analysis, are divided into the function of accommodation and the function of handling and that when, in the place of a one-piece container combining these two functions, two separate members adapted to fulfill such different functions respectively are assembled in a separable manner, only the member fulfilling the function of accommodation and soiled by the content remaining after use can be separated and thrown away. This idea was applied to the aforementioned paint mixing container: A receptacle member conforming to the configuration of a container of the kind heretofore used for a similar purpose was prepared, a container member of the shape of an ordinary drinking glass was formed of a synthetic resin and the container member was set in position inside the receptacle member. When the assembled container was put to use, it was learnt that the paint tended to smear the receptacle member when the assembled container was tilted to pour out the paint and the container member would slip out of the receptacle member when the assembled container was tilted to a certain degree. These facts constituted obstacles to effective use of the assembled container. The present invention has been perfected to overcome these drawbacks. The basic idea of the invention relates to providing an extended edge on the upper end of the container member inserted in the receptacle member and, after the container member has been secured within the receptacle member, folding down the extended edge outwardly and thereby causing the folded portion to take a firm hold of the upper edge of the receptacle member.
SUMMARY OF THE INVENTION
The disposable container of the present invention comprises, in combination, a disposable container member possessed of a shape suitable for accommodation and use of a substance to be contained therein, made of a thin-walled synthetic resin material capable of self-sustaining the shape mentioned above and provided at the upper end thereof with an extended edge which is folded down outwardly; and a receptacle member including an upper-edge portion of size and shape such that it receives a squeezing force on the periphery thereof when it is received under the folded-back portion of the aforementioned extended edge of the container member, a supporting portion continuing into the upper-edge portion and serving to retain the upper-edge portion in a desired posture and also optionally serving to hold in position the barrel of the container member
