Abstract
A package includes a peripheral flange around a blister defining an open cavity for receiving a product and a compressible insert for securing the product against movement in the cavity. At least one projection on the insert extends laterally from the cavity over the peripheral flange, and a lid covering the cavity is continuously sealed to the peripheral flange and the projection along a single seal. A method for sealing products in the package includes supporting the peripheral flange on a rigid support surface, and compressing the lid against the peripheral flange with heat and pressure to compress the projection between the lid and the peripheral flange and heat seal the projection to the lid simultaneously with sealing of the lid to the peripheral flange along the peripheral seal.
Claims22
A package for holding a product comprising
- a body having a recess therein for receiving a product;
- a foam insert disposed in said recess for holding the product within said body;
- a cover disposed over said body and completely covering said recess;
- flanges on said insert disposed laterally of said recess and compressed between said body and said cover;
- and
- a seal joining said cover to said body around said recess and to said flanges, whereby said insert remains joined to said cover and is removed with said cover when said cover is removed from said body.
A package for holding at least one product comprising
- a body having a depression therein for receiving at least one product;
- a solid block of foam material disposed in said depression for securing the at least one product in said depression, said block having a thickness;

- a rim on said body disposed around said depression;
- and
- flanges of lesser thickness than said block extending from said block and disposed between said rim and said lid, said lid being continuously sealed to said flanges and said rim around said depression.
A package for holding a product comprising
- a blister body defining a recess for receiving a product and a border disposed around said recess;
- a foam insert disposed in said recess to hold the product within said body, said insert having a planar base with a pair of opposing co-planar flanges extending outwardly from said base and overlying said border;
- and
- a cover sheet disposed over said base and heat sealed to said border and said flanges continuously around said recess.
