The invention concerns a drinking cup intended for repeated use. The cup is manufactured from a resilient and flexible plastics material. The cup comprises a lower cylindrical section, a thinner middle section, and an upper section which essentially has the shape of a truncated cone. The walls of this cone-shaped section may converge upwards. The upper section may be folded downwards, into the lower section, the middle section serving as the folding line. A handle is provided at the upper cup section. In the area where the handle is provided the upper section has a straight portion which imparts to the upper cup section a slightly oval shape, serving to make it easier to drink from the cup. In addition, the handle is formed at a rigid area of the upper section, whereby folding downwards of the upper section into the lower section is made easier.
An improved drinking cup manufactured from a resilient and flexible synthetic resin material and intended for repeated use, comprising a lower section, at least one upper section, said upper section being essentially in the shape of a truncated cone which cone-shaped section may be turned downwards and folded upon the lower section to reduce the volume of the cup, and a handle, said handle provided on said upper section of the cup, the improvement comprising an essentially straight portion in the upper section of the cup adjacent the handle, said straight portion imparting to the upper section a slightly oval shape serving to facilitate drinking from the cup and a rigid portion of said upper section of the cup, said handle formed at said rigid portion.
A reusable drinking cup manufactured from resilient and flexible synthetic resin material, said cup comprising a peripheral wall having a lower section and an upper section, said upper section having generally the shape of a truncated cone and capable of being turned downwardly relative to said lower section so as to be folded upon said lower section to reduce the volume of the cup, the peripheral wall of said upper portion having an essentially straight portion imparting to said upper section a slightly oval shape, said essentially straight portion having a handle protruding therefrom the area of said straight portion adjacent said handle being more rigid than the remaining portion of said upper section.
