Abstract
A thermoformed plastic package made of a single piece of formed plastic sheeting folded upon itself along a hinge band. The back and front sections form an enclosure, preferably for a tape roll, and have contacting portions which include flat areas and interlocked undercut mating areas which extend from a first position near the hinge around the enclosure to a second position near the hinge, and preferably along the hinge as well. The hinge band preferably includes a center portion narrower than the total width of two side portions therealong, and serves to draw the face-to-face sections of the package together along the hinge. A tape channel extending from the enclosure provides frictional engagement tape being dispensed.
Claims19
In a thermoformed plastic package, the improvement comprising:
- a single piece of formed plastic sheeting folded upon itself along a hinge dividing the piece into back and front sections;
- the back and front sections having (a) spaced portions forming an enclosure, and (b) contacting portions including back and front main flat areas, respectively, and interlocked back and front mating areas projecting from their respective main flat areas;
- and
- the mating areas having interlocked undercut male and female configurations extending from a first position near the hinge around the enclosure to a second position near the hinge and spaced from the first position;
- whereby the sections are firmly held together.
In a tape-dispensing package of the type having an enclosure for a tape roll and a tape exit channel extending from the enclosure, the improvement comprising:
- a single piece of formed plastic sheeting folded upon itself along a hinge dividing the piece into back and front sections;
- the back and front sections having (1) spaced portions forming the enclosure, and (2) contacting portions including back and front main flat areas, respectively, and back and front mating areas projecting from their respective main flat areas;
- and
- the channel having opposite sidewalls formed by two parallel portions of the mating areas and top and bottom walls formed by portions of the back and front main flat areas, said parallel portions of the mating areas having interlocked undercut male and female configurations,
- whereby tape within the channel is frictionally engaged by the top and bottom walls.
In a dispensing package of the type having an enclosure for a material to be dispensed and an exit channel extending from the enclosure to an exit, the improvement comprising:
- a single piece of formed plastic sheeting folded upon itself along a hinge dividing the piece into back and front sections;
- the back and front sections having (a) spaced portions forming the enclosure, and (b) contacting portions including back and front main flat areas, respectively, and back and front mating areas projecting from their respective main flat areas;
- the channel having top and bottom walls formed by portions of the back and front main flat areas;
- the mating portions having interlocked undercut male and female configurations extending from a first position near the hinge around the enclosure to a second position near the hinge;
- and
- the hinge including means to draw the back and front flat areas together,
- whereby the sections are firmly held together and material within the channel is frictionally engaged by the top and bottom walls.
