Emery's invention relates to single use containers and receptacles made entirely
of some lightweight, inexpensive material, as molded pulp, paper, or the like. Emery
states (column 1, lines 14-26) that:
One problem with such a receptacle or container made of such
light-weight material is that the article is easily tilted or tipped over when placed
on a flat supporting surface, as a table in the case of a plate or dish, or the floor
in the case of a cuspidor.
Considering the cuspidor as characteristic of the general line of
light-weight single service receptacles and containers made of molded pulp or
the like, it is to be noted that the problem involved is to stabilize the article in the
region of its base so as to prevent it from being tipped over or tilted.
Emery's invention contemplates a single service receptacle or container which
embodies as an inherent feature of its construction an element of two-fold function, viz.
a stabilizer to steady the receptacle against tilting or tipping over and a mechanical
reinforcement or truss to stiffen and strengthen the receptacle against collapse or
distortion. According to Emery's concept, the base of the receptacle or container is
provided with an annular rim extension adapted to rest flatly upon the table, floor or
other supporting surface and by such flat contact with such supporting surface to impart
stability to the article, as well as generally to stiffen and reinforce the same in the region
where it is normally weakest and most susceptible to distortion.
Figures 1 and 2 of Emery illustrate a cuspidor 10 made of molded pulp or other
light weight inexpensive fibrous material, and embodying the features of his invention.
