Patent ID: 8201688

Claim:
A flexible container for a fluid, for use with a personal hygiene device, comprising: a flexible bag pre-filled with a dentifrice or shaving fluid having a front panel portion and a rear panel portion and sealed along a bottom edge thereof, defining an interior volume for fluid, and further having a gusset along each longitudinal edge thereof which connect the front and rear panel portions thereof and allow the front and rear panel portions to expand away from each other when the bag is filled, wherein the bag includes two sealed wing portions of substantially equal width on either side of a central portion at a top end thereof, wherein the central portion is sealed to a spout element which is constructed to permit exit of fluid from the bag after it has been filled, wherein the sealed central portion extends beyond opposing sides of the spout element to the wing portions, wherein the wing portions extend above the central portion of the bag, terminating approximately in the plane of a top edge of the spout element, and wherein the wing portions each include an inner edge which extends to the central portion separately from the spout element, wherein the wing portions each include an open section which extends above the gusset in fluid communication with the interior volume of the container, the open sections extending inwardly from opposing side edges of the container a small distance compared to the width of the container, the remainder of the wing portions, to the central portion, being sealed, such that the fluid in the pre-filled bag extends into the open sections but not the sealed remainder of the wing portions, wherein the open sections each have a width approximately equal to the sealed remainder of the wing portions, and wherein the sealed remainder of the wing portions have a width similar to the sealed section of the central portion, which extends to the spout element, the open sections allowing the gusset to expand fully, permitting the bag to fill completely.
