Abstract
An overwrap container includes a base container having a first side seam on a side wall that extends along a longitudinal axis to define an internal volume, and a bottom connected to the side wall. An overwrap is positioned over the side wall of the base container and has a second side seam aligned longitudinally with the first side seam. Connecting elements are positioned between the side wall of the base container and the overwrap, and join the side wall of the base container and the overwrap together except in an area along the aligned first and second seams to define an uniform spacing extending continuously between the side wall and the overwrap forming an air gap there between.
Claims15
An overwrap container comprising:
- a base container having a first side seam on a side wall that extends about a longitudinal axis to define an internal volume, and a bottom connected to the side wall, the first side seam being formed with overlapping opposite base container side edges which are heat sealed together;
- a pre-glued overwrap positioned over the side wall of the base container, the overwrap having a second side seam aligned longitudinally with the first side seam, the second side seam being formed with overlapping opposite overwrap side edges which are joined together by an adhesive extending along substantially an entire length of one of the overwrap side edges;
- and
- connecting elements positioned between the side wall of the base container and the overwrap, and joining the side wall of the base container and the overwrap together except in an area along the aligned first and second side seams to define a uniform spacing extending continuously between the side wall and the overwrap forming an air gap therebetween.
A method for producing an overwrap container comprising the steps of:
- a) providing a base container having a first side seam on a side wall that extends about a longitudinal axis to define an internal volume, and a bottom secured to the side wall, the first side seam being formed with overlapping opposite base container side edges which are heat sealed together;
- b) providing the side wall of the base container with connecting elements around an outer periphery of the side wall except for an area along the first side seam;
- and
- c) providing a pre-glued overwrap having a second side seam over the side wall of the base container such that the first side seam of the base container and the second side seam are aligned together, and such that the overwrap is joined by the connecting elements to the outer periphery of the side wall of the base container except in an area along the aligned first and second side seams to define an overwrap container having a uniform spacing extending continuously between the side wall of the base container and the overwrap, the second side seam being formed with overlapping opposite overwrap side edges which are joined together by an adhesive extending along substantially an entire length of one of the overwrap side edges.
