Abstract
Containers having enhanced emptying capability include a filling/emptying opening disposed closely adjacent the container sidewall and extending through integral top closure structure. The container sidewall has a portion contiguous with the filling/emptying opening which extends therefrom without radial step discontinuity, thus avoiding well formation adjacent the opening.
Claims14
A container having a hollow integrally structured body comprising a base, a sidewall extending upright from said base and a top closure having a surface expanse with an access port extending therethrough, said sidewall having a portion contiguous with said access port and extending downwardly and outwardly with progressively decreasing thickness for defining an interior surface extending from said access port continuously arcuately to the expanse of said sidewall adjacent said sidewall portion.
A container having a hollow integrally structured body comprising a base, a sidewall extending upright from said base, a top closure having an access port situate adjacent said sidewall and a neck member extending upright from said access port, said sidewall including a portion contiguous with said neck member and said access port and extending downwardly and outwardly to the expanse of said sidewall adjacent such sidewall portion, the thickness of said sidewall portion decreasing with travel thereof from said access port to said sidewall adjacent expanse, whereby said sidewall portion defines an interior surface extending continuously arcuately from said access port to said sidewall adjacent expanse.
A container having a hollow integrally structured body comprising a base, a sidewall and a top closure having an access port, said sidewall defining a first interior surface of cylindrical configuration and extending upright from said base and a second interior surface contiguous with said first surface and said access port, said second surface being continuously arcuate and of perimetrical curvature opposite to the curvature of said first surface.
