A package tray configured for use with at least one other such tray in forming reclosable enclosed packages includes a recess portion having an upper edge, a flange portion projecting from the upper edge and having upper and lower sides, at least one snap fastener of a first type located on the flange portion, and at least one snap fastener of a second type located on the flange portion in spaced relationship to the at least one fastener of the first type. Each of the first and second type fasteners is configured to be fastenable on both said upper and lower sides of said flange portion to opposing fasteners of like package trays. The first and second type fasteners are disposed on the flange portion so that when multiples of the package trays are placed in vertically stacked relationship, at least one opposing pair of the fasteners on adjacent trays engage each other to secure the trays together in one of a nested and an opposing relationship.

Package tray having reversible nesting and enclosing fastening feature

A process for producing a thermoformed article having a first portion with a first wall thickness, and a second portion with a second wall thickness, the first portion having a thicker wall thickness than the second portion, the process including selectively cooling the first portion during a thermoforming cycle so that thermoformable material from the first portion is prevented from migrating to the second portion.

Process for producing thermoformed article employing selective cooling

A sealable thermoformed container for containing liquids including a cup portion with an open end and a lid portion that is separable and sealably detachable from the cup. A cup sealing formation and lid formation are provided so that a liquid tight seal between the cup are formed when the lid is press-fit onto the top of the cup. Additionally, a detachable and disposable funnel may be attached to the cup for use in directing a stream of liquid into the cup prior to sealing.

Sealable thermoformed container for liquids

An apparatus for making accurate cuts in thermoformed articles projecting vertically above a generally planar sheet of thermoformable material includes a base plate having a lower surface, at least one pair of knives being mounted to the lower surface of the base plate to depend therefrom and being capable of limited movement, each knife having a cutting portion and a guiding portion, the guiding portion of each knife being angled relative to the longitudinal axis of each knife and being divergent from the adjacent knife. Each pair of knives is disposed on the base plate, and the base plate is disposed relative to the sheet of thermoformable material so that thermoformed articles advanced toward the apparatus will engage the guiding portions of the knives and cause the knives to slidingly contact sides of the articles, and upon lowering the base plate toward the sheet, the cutting portions of the knives are positioned to create score lines in the sheet which are substantially flush with the sides of the articles.
