Abstract
A plurality of like, thermoformable plastic laminate articles and a method of making same in which a substantially flexible plastic sheet is bonded to a substantially rigid thermoformable plastic core. The sheet has markings disposed on one face thereof, and the markings are disposed at the same predetermined location with respect to the core for all of the plurality of articles.
Claims41
A plurality of like, thermoformable plastic laminate structures, each structure comprising:
- a rigid thermoformable plastic core;
- and
- a flexible transparent plastic sheet permanently laminated to the core so that the shape of the sheet conforms to the shape of the core, the sheet having an ink disposed on one face thereof,
- the ink being disposed at the same predetermined location with respect to the core for all of the plurality of structures, the ink being in a shape and/or a color which is predistorted.

A plurality of like, substantially inflexible plastic composite articles, each article comprising:
- an inflexible non-foam plastic core;
- and
- a flexible plastic sheet laminated to the face of the core so that the shape of the sheet conforms to the shape of the non-foam core, the sheet having a marking adhered to the side thereof which is affixed to the core,
- wherein the position of the marking with respect to the core is registered for all of the plurality of articles, the marking being disposed on two angled planes of each article, the marking on at least one angled plane being registered for all of the plurality of articles.
1 more element
A thermoformable plastic product comprising:
- a rigid thermoformable plastic core;
- a flexible, transparent plastic sheet laminated to the core, so that the shape of the sheet conforms to the shape of the core;
- and
- a marking adhered to the sheet in registration with a predetermined location on the core, the marking being disposed on one face of the sheet, the marking being in a shape and/or a color which is predistorted.
1 more element
A thermoformed plastic container comprising:
- an inflexible non-foamed plastic layer;
- an adhesive layer adhered on one face of the inflexible layer;
- and
- a flexible, transparent plastic layer having printing on a face thereof which is laminated to the inflexible layer by the adhesive layer, the shape of the flexible plastic layer conforming to the shape of the non-foamed core, the printing being non-randomly located with respect to the inflexible layer, the printing being disposed on two angled planes of the container, the printing on at least one angled plane being non-randomly located with respect to the inflexible layer.
1 more element
A method of manufacturing a plurality of thermoformed plastic articles, comprising the steps of:
- fixing a plurality of markings on one face of a flexible transparent plastic sheet at least one of the markings having a shape and/or a color which is predistorted;
- positioning the plastic sheet with respect to a rigid plastic layer having a plurality of core portions, to cause locations of the plurality of markings to be in registration with identical predetermined locations on the core portions, respectively;
- laminating the plastic sheet to the plastic layer to cause the markings to be in registration with the predetermined locations and to cause the shape of the sheet to conform to the shape of the plastic layer.
A method of manufacturing a plastic laminate article, comprising the steps of:
- marking one face of a flexible plastic sheet with a marking having a shape and/or a color which is predisorted;
- laminating the sheet to a rigid plastic layer with the marking being adjacent the layer so that the shape of the sheet conforms to the shape of the plastic layer, a predetermined portion of the marking being in registration with a predetermined section of the layer;
- positioning the laminated sheet and layer in a forming station so that the registered marking is at a predetermined position in the forming station;
- and
- forming the article to cause the registered marking to be at a predetermined location on the formed laminate article.
2 more elements
A method of producing a plurality of plastic composite articles, comprising the steps of:
- reverse printing a plurality of like markings on a transparent, flexible plastic sheet;
- laminating the sheet to a rigid non-foamed plastic layer using an adhesive that has common properties with the sheet and the layer so that the shape of the sheet conforms to the shape of the non-foamed plastic layer;
- positioning the bonded sheet and layer in a thermoforming station such that the plurality of like markings are precisely located at a corresponding plurality of locations in the thermoforming station;
- thermoforming a plurality of three-dimensional articles such that each of the plurality of like markings is at the same predetermined location on each of the plurality of articles, respectively, the marking of each composite article being disposed on two angle planes, the marking on at least one angled plane being at the same predetermined location for the corresponding one angle plane for each of the plurality of articles;
- and
- separating the plurality of articles from one another.
