A container for storing, dispensing and applying solid and semi-solid materials, and being fillable, optionally, from the top or from the bottom. The container assembly is characterized by improved seals between a product supporting and elevating platform and the circumscribing body of the container and by simple yet highly effective bottom closure interlocks, seals, and vents rendering feasible the filling of the container conveniently from the bottom as well as from the top.

A container for storing, dispensing and applying solid and semi-solid products, said container having a tubular, open-ended body and being readily fillable, optionally from the top or from the bottom, said body including an unrestrictedly open lower end section defining a skirt, said skirt defining at a lower end thereof an enlarged, unobstructed opening prividing free access to said body of said container for slidingly and telescopically introducing a product-supporting platform therewithin and for inserting a body closure thereinto, a plunger-like, generally trough-shaped, product-supporting platform spanning said container and being in stressing contiguous engagement with said tubular body interiorly thereof, said platform being forceably insertable through said unobstructed opening of said body through said completely open, skirt-defining end section thereof after filling said container from a bottom, unobstructed opening in said body of said container, said platform being formed with a floor and with a bounding upstanding circumferential wall, an outer circumscribing face of said circumferential wall being tapered radially inwardly upwardly, and being tapered radially inwardly downwardly with respect to an annular locus intermediate upper and lower limits of said wall to define upwardly and downwardly shiftable, low-friction, product-stabilizing, and container-sealing horizontally disposed, container-body-stressing rib means for facilitating forced telescopic insertion of said platform axially into said container from said open lower end section thereof without destroying and without impairing integrity of a stressing seal provided by said rib means with said container, interiorly thereof, said rib means being effective, upon forceably urging said platform slidably through said skirt, for preserving a compression seal between said platform and a circumscribing, abutting, bounding wall of said container at an inner surface thereof to prevent product in said container from invading a special zone below said platform, and a closure plug for insertion into said open lower end section of said body of said container as a closure therefor for retaining a product stored in said container and to be dispensed therefrom at an end thereof opposed to said closure plug. In a container for storing, dispensing and applying solid and semi-solid products, said container having a tubular, open-ended body and being readily fillable, optionally, from the top or from the bottom, said body being completely open at a lower end section thereof defining a skirt, said container having a lower closure, and said skirt having interlock means intergrally formed therewith for intercoupling locking engagement with said closure for said container, said skirt being flared radially outwardly and downwardly interiorly of said container to provide an upwardly and inwardly tapering, enlarged, unobstructed access opening into said body of said container for slidably introducing a product-supporting platform thereinto and for insertion of a closure plug thereinto, a plunger-like, generally trough-shaped, product-supporting platform spanning said container interiorly thereof, said platform having a floor and an integrally-formed, upstanding circumferential wall, and being insertable from a bottom open end of said open-ended body through said completely-open end-section thereof after filling said container through the bottom thereof, the improvement wherein said wall is formed with an outer face thereof which is tapered radially inwardly upwardly and which is tapered radially inwardly downwardly with respect to an annular locus intermediate upper and lower limits of said wall to define an upwardly and downwardly shiftable, low-friction, product-stabilizing, container-stressing, and container-sealing rib means for facilitating forced telescopic insertion of said platform axially into said container from an open lower end section thereof without impairing or destroying the integrity of a container-stressing seal provided by said rib means, said rib means being resiliently deformable for permitting entry of said platform up through the open bottom end of said container and said rib means being effective for preserving a container-stressing seal between said platform and a bounding wall of said container at an inner surface thereof to prevent product in said container from invading a zone below said platform including during filling of said container from a top thereof.
