Dispensing Bag with Longitudinal Split

Abstract

An improved dispenser bag, suitable for use as a pastry bag or mortar bag is disclosed. The bag is a flexible and conical-shaped with a first end opening formed by truncation of the bag near the apex of the cone and a second opening at the opposite end. In embodiments the surface of the bag is split a distance longitudinally from the second opening for a distance and can be releasable opened and closed with a fastener. The lateral opening allows easy access to the interior region of the bag for filing and the removal or insertion of a tubular tip. An extended flap member is attached to the inside surface of the bag and is formed to extend inside of, and across, the split, so as to minimize loss of material through the split.

I claim: 
     
         1 . A dispensing bag, as used to hold and dispense a viscous material on a substrate, comprising:
 a flexible, conical-shaped bag having a curved surface tapering toward an apex;   said bag having an first end opening formed by truncation of the bag near the apex of said cone and a second end opening opposite the first end, and   a split formed in said surface that longitudinally extends from said second end opening, said split having two opposite sides and said split extends to a location near the first opening, and a resealable closure elements along the sides of said split for opening and closing the opposite sides of the split to allow improved access to an interior region of said bag.   
     
     
         2 . The dispensing bag recited in  claim 1  further comprising a flap member, said flap member attached to the inside of the bag surface and formed to extend inside of and across the split so as to preclude loss of material through the split. 
     
     
         3 . The dispensing bag recited in  claim 1  wherein said closure element comprises a zipper and said zipper opens said split from said second opening. 
     
     
         4 . The dispensing bag recited in  claim 1  wherein said zipper forms a fluid resistant seal. 
     
     
         5 . The dispensing bag recited in  claim 1  wherein said closure element comprises a hook and loop fastener. 
     
     
         6 . The dispensing bag recited in  claim 1  further comprising a tubular tip and said bag is adapted to receive and seat said tip. 
     
     
         7 . The dispensing bag recited in  claim 1  wherein said closure element comprises a plurality of snap fit closures. 
     
     
         8 . The dispensing bag recited in  claim 1  wherein said closure element comprises a channel lock seal 
     
     
         9 . The dispensing bag recited in  claim 8  wherein said closure element comprises a fluid tight seal. 
     
     
         10 . The bag recited in  claim 1 , where said overlapping flap and interior surface of said bag form a contact surface and said contact surfaces comprise a vinyl material. 
     
     
         11 . A bag comprising a flexible, conical-shaped container having a curved surface tapering toward an apex;
 said bag having a first end opening formed by truncation of the bag proximate the apex of the cone and a second opening at the base of said cone;   said bag further comprising a split, said split extending along said surface of said bag and extending from longitudinally from said first end opening to said second openings, and said split having two opposing edges, and   a closure element to releasably open and close said opposing edges.   
     
     
         12 . The dispensing bag recited in  claim 11  wherein said closure element causes said opposing edges to close said and said opposing edges abut one another opposing edge to opposing edge. 
     
     
         13 . The dispensing bag recited in  claim 11  wherein said opposing edges overlap one another when said split is closed. 
     
     
         14 . The dispensing bag recited in  claim 11  wherein said closure element comprises a zipper. 
     
     
         15 . The dispensing bag recited in  claim 11  wherein said closure element comprises a hook and loop fastener. 
     
     
         16 . The dispensing bag recited in  claim 11  wherein said closure element comprises a channel lock closure.
