Container with Gasket Seal

Abstract

A container ( 210 ) for holding granular or powdered material and formed by a top wall ( 212 ), a bottom wall ( 214 ), a front wall ( 216 ), a rear wall ( 218 ), a first side wall ( 220 ), and a second side wall ( 222 ). A rotatably removable lid (D) is interiorly mounted with a scoop ( 32 ) and is pivotally hinged to a collar ( 300 ) that includes a sealing gasket ( 330 ). The collar ( 300 ) mounts to the walls of the container ( 210 ). A sealing wall 240 of the lid (D) cooperates with the gasket 330 to prevent the contents from spilling. The container ( 210 ) incorporates powder control features, a container wall junction ( 50 ) preferred geometry and congruent scoop ( 32 ) enabling convenient access to the contents, a tolerance variation accommodating and strength improving, J-shaped collar ( 300 ) and interlocking indentations ( 290 ) and flex clips ( 310 ), and a pressure controlling portion ( 350 ) that prevents unwanted deformation due to pressure differentials.

 walls defining interior and exterior surfaces and an interior space, the walls having an upper portion near an upper end of the walls that defines a sealing flange, the sealing flange having an internal edge that defines an opening to the interior space;   a collar having an interior surface adapted to fit around the container near the upper portion and defining a subcollar space between the exterior surface of the container and the interior surface of the collar;   a removable lid attached to the collar and having an interior surface which, when in a closed position, is adapted to cover and seal the opening, the lid having a sealing wall depending from its surface and projecting toward the sealing flange;   a flexible gasket dimensioned to removably rest against the sealing flange and carried from a surface of a group that includes (a) the interior surface of the collar, (b) the interior surface of the walls, and (c) the sealing wall of the lid; and   wherein when the lid is in the closed position, the gasket, the sealing wall and the sealing flange are dimensioned such that the sealing wall biases the flexible gasket against the sealing flange to seal the subcollar space from the container interior.   
   
   
       2 . The sealable container according to  claim 1 , wherein the collar includes a raised seat that carries the gasket so that it projects inwardly to bias against and to extend beyond the internal edge of the sealing flange. 
   
   
       3 . The sealable container according to  claim 1 , wherein the gasket is arranged to remain biased against the sealing flange when the lid is in an open position. 
   
   
       4 . The sealable container according to  claim 1 , wherein the gasket attaches to and depends from the interior surface of the collar and has an internal edge extending inwardly beyond the internal edge of the sealing flange. 
   
   
       5 . The sealable container according to  claim 2 , further comprising a removable seal extending across the opening and attaching to the sealing flange beneath the flexible gasket; and
 wherein the flexible gasket flexes to enable removal of the removable seal and thereafter flexes back to rest against the sealing flange.   
   
   
       6 . The sealable container according to  claim 1 , wherein the walls are arranged to form the container to have an approximately cuboid shape. 
   
   
       7 . The sealable container according to  claim 1 , further comprising:
 a scoop holder attached to the interior surface of the lid for holding a removable scoop having a bowl carried from a handle, the scoop holder formed with a first bowl cover bracket and having a retainer to immobilize the handle and a first projection extending from the interior surface having a handle holding notch to hold the handle away from the interior surface in a grasping position.   
   
   
       8 . The sealable container according to  claim 1 , wherein the upper end of the walls are formed with a plurality of indentations having upper lug ledges that are spaced apart by strengthening bridges, and wherein the collar is formed to have a substantially J-shaped cross section and to carry a plurality of spaced apart flex clips having retainer faces that are juxtaposed to engage the upper lug ledges when the collar is assembled to the upper end of the walls. 
   
   
       9 . A sealable container, comprising:
 walls defining interior and exterior surfaces and an interior space, the walls having an upper portion near an upper end of the walls that defines a sealing flange, the sealing flange having an internal edge that defines an opening to the interior space;   a collar having an interior surface adapted to fit around the container near the upper portion and defining a subcollar space between the exterior surface of the container and the interior surface of the collar;   a removable lid carried on the collar and having an interior surface which, when in a closed position, is adapted to cover and seal the opening, the lid having a sealing wall depending from its surface and projecting toward the sealing flange, the sealing wall having an inwardly funneled lower edge; and   wherein when the lid is in the closed position, the sealing wall and the sealing flange are dimensioned such that the sealing wall contacts the sealing flange to have the inwardly funneling lower edge projecting below the internal edge of the sealing flange to seal the subcollar space from the container interior.   
   
   
       10 . The sealable container according to  claim 9 , further comprising:
 a flexible gasket dimensioned to removably rest against the sealing flange and being carried from a surface of a group that includes (a) the interior surface of the collar, (b) the interior surface of the walls, and (c) the sealing wall of the lid; and   wherein when the lid is in the closed position, the gasket, the sealing wall and the sealing flange are dimensioned such that the sealing wall biases the flexible gasket against the internal edge of the sealing flange to seal the subcollar space from the container interior.   
   
   
       11 . The sealable container according to  claim 10 , wherein the collar includes a raised seat that carries the gasket so that it projects inwardly to extend beyond the internal edge of the sealing flange. 
   
   
       12 . The sealable container according to  claim 10 , wherein the gasket attaches to and depends from the interior surface of the collar, and wherein when the lid is in an open position, the gasket is arranged to remain biased against the sealing flange.

 wherein the flexible gasket flexes to enable removal of the removable seal and thereafter flexes back to rest against the sealing flange.   
   
   
       14 . A sealable container, comprising:
 walls defining interior and exterior surfaces and an interior space, the walls having an upper portion near an upper end of the walls that defines a sealing flange, the sealing flange having an internal edge that defines an opening to the interior space;   a collar having an interior surface adapted to fit around the container near the upper portion and defining a subcollar space between the exterior surface of the container and the interior surface of the collar, the collar having an integral gasket projecting inwardly and in a direction to be biased against the sealing flange;   a removable lid pivotable about the collar and having an interior surface which, when in a closed position, is adapted to cover and seal the opening, the lid having a sealing wall depending from its surface and projecting toward the sealing flange; and   wherein when the lid is in the closed position, the gasket, the sealing wall and the sealing flange are dimensioned such that the sealing wall biases the integral gasket against the internal edge of the sealing flange to seal the subcollar space from the container interior.   
   
   
       15 . The sealable container according to  claim 14 , wherein the integral gasket extends inwardly beyond the internal edge of the sealing flange.
