Abstract
A multi-compartment bag having at least two compartments of polymeric material, the subsequent compartments being monolithic with the first compartment having an interconnection of two spaced seal strips. There is also provided a method of making a multi-compartment bag.
Claims14
A multi-compartment bag, comprising:
- a first compartment of polymeric material having a first closed or closable end;
- and
- a second compartment of polymeric material that is monolithic with said first compartment and having a second closed or closable end(s), wherein said first and second compartments are joined along an intermediate section spaced between their closed or closable ends to form at least one interconnecting heat seal strip therebetween.
A multi-compartment bag in the form of a flattened generally tubular member formed out of a sheet of polymeric material;
- said sheet having confronting longitudinal edges extending the length of said tubular member, said edges being joined together and folded against an outer surface of said bag;
- opposite ends of said bag being closed;
- and
- an intermediate seal strip dividing said bag into compartments of unequal size sealed from one another.
A method of producing a multi-compartment bag comprising the steps of;
- providing a generally rectangular sheet of film of polymeric material;
- joining longitudinal edges of said sheet together;
- heat-sealing ends to close opposite ends of a continuous bag;
- and
- heat-sealing an intermediate portion of said bag in a direction parallel to said opposite ends whereby to define a pair of separate compartments in said bag.
A method of producing and filling a multi-compartment bag comprising the steps of;
- providing a generally rectangular sheet of film of polymeric material;
- joining longitudinal edges of said sheet together;
- creating dual heat seals on ends to close opposite ends of a continuous bag;
- separating said dual heat seals;
- filling said bag with a pre-determined weight of product;
- heat-sealing an intermediate portion of said bag with dual strips in a direction parallel to said opposite ends whereby to define a pair of separate compartments in said bag;
- filling a separate compartment with a pre-determined weight of product;
- and
- applying a dual heat seal on an end of said separate compartment to close said compartment.
