Improved construction of molded plastic containers

Claim 1

A package for flowable contents having tube-like side walls (1 to 4), bottom (5) and top wall (6) and with a closable pourer device (7) having a cylindrical edge, all parts (1 to 7) of the package consisting of synthetic plastics material, two tub-shaped parts (I,II), each of which forms an entire side wall (3,4), two oppositely adjacent fractional side walls part (1',2') with peripheral rim portions 13, a fractional bottom part (5') a fractional upper wall part (6') with peripheral rim portion 13 and with a fractional pouring device (7 to 9), each tub-shaped part being connected to one another and individually sealed by means of a synthetic plastics film (14) applied to and projecting beyond the rim (13) in the form of a web (15), and in that the cylindrical edge (8) of the pourer device (7) extends beyond the web (15) of synthetic plastics film (14) to both tub-shaped parts (I,II) and in that the thickness of the synthetic plastics film (14) is 0.01 to 0.5 times the thickness of the rim portions of the tub-shaped parts (I,II), whereby the thickness of the film provides means facilitating the ready passage of heat through the portions of the film applied to the rim portions of the tub-shaped parts, further characterized in that the rim (13) of the tub-shaped part (I,II) and the web (15) of synthetic plastics film (14) which projects beyond the rim (13) while resting thereon engage centrally along the surfaces (1, 6, 2) of the package in essentially a U-shaped pattern from one side wall (1) beyond the top wall (6) to the opposite side wall (2) and centrally, ending in each case folded over onto itself at the edge (24) between side wall (1, 2) and bottom (5).
