Abstract
A container for holding an adhesive is frusto-conical or cylindrical in shape and has a bottom wall and a pleated side wall. The container has a twin substrate composition throughout. The first substrate is paper having a small enough caliper to allow for proper forming and to maintain the shape of the container once it is formed. The second substrate is a polyester film thin enough to allow the paper substrate to maintain its shape, but sufficiently thick to hold the adhesive or other material to be stored. The first and second substrates are glued together with a water-based or hot melt pressure-sensitive adhesive.
Claims15
A container for holding an adhesive, said container comprising a sheet, said sheet formed as a pleated cylinder having a bottom wall and a side wall having a plurality of pleats, said sheet comprising:
- a) a first substrate made of paper;
- and
- b) a second substrate, said second substrate being comprised of polyester film having a silicone coating on the interior surface thereof relative to said container;
- and
- c) adhesive joining said first and second substrates.
A container for holding an adhesive, said container made from a sheet and being generally frusto-conical in shape having a flat bottom wall and a flexible continuously pleated side wall, said sheet comprising:
- a) a first substrate made of a shaping material;
- b) a second substrate, said second substrate comprising a second, strength-imparting material;
- and
- c) adhesive joining said first and second substrates.
A container for holding an adhesive, said container made from a sheet and being generally frusto-conical in shape having a flat bottom wall and a flexible continuously pleated side wall, said sheet comprising:
- a) a first substrate made of 60 pound offset paper having a thickness not greater than 7 caliper, said paper permitting the forming and maintenance of the shape of said container;
- b) a second substrate, said second substrate comprising
- 1) a polyester film having a thickness not greater than 1.0 mil capable of withstanding temperatures up to 375.degree. F.;
- and
- 2) a silicone coating on the interior surface thereof relative to said container;
- and
- c) a hot melt, pressure-sensitive adhesive joining said first and second substrates.
