Abstract
A packaging system includes a container and an unopened lid. The unopened lid includes a central planar region and a lid rim. The lid rim has a lid rim inner wall, a lid rim outer wall, a lid flange and a first tab. The first tab extends in a plane parallel to the central planar region. The first tab also extends outside the lid rim outer wall. A partially cut region is located on the lid rim outer wall, extends around most of the lid rim outer wall, and extends adjacent the first tab. The lid flange extends in a plane parallel to the central planar region. The lid flange also extends outside the lid rim outer wall. The container includes a container flange. The lid flange is welded to the container flange.
Claims42
A method of fabricating a package, comprising:
- a. providing a lid, wherein said lid includes a central planar region and a lid rim region, wherein said lid rim region has a lid rim, wherein said lid rim region surrounds said central planar region, wherein said lid rim has a lid rim inner wall and a lid rim outer wall, wherein said lid rim further includes a first tab, wherein said first tab extends in a plane parallel to said central planar region, wherein said first tab extends outside said lid rim outer wall;
- b. providing a container, wherein said container includes a container rim region having, a container rim, wherein said lid rim fits on said container rim, wherein said lid rim inner wall is for positioning inside said container rim and wherein said lid rim outer wall is for positioning outside said container rim;
- c. partially cutting a line in said lid rim outer wall, wherein said partially cutting includes at least one laser treating from the group consisting of laser scribing, laser cutting, and laser slitting, wherein said partially cutting provides a partially cut line extending around most of said lid rim outer wall, wherein said partially cut line defines a first portion of said lid rim outer wall and a second portion of said lid rim outer wall, wherein said partially cutting provides sufficient material weakening for pull-separating along said partially cut line when opening the package is desired, wherein said first tab is located for providing said pull-separating when said first tab is pulled;
- and
- d. welding said second portion to said container rim region.
A method of fabricating a package, comprising:
- a. providing a container having a container flange;
- b. providing a lid, wherein said lid includes a central region and a lid rim region, wherein said lid rim region has a lid rim and a lid flange, wherein said lid rim region surrounds said central region, wherein said lid rim has a lid rim inner wall and a lid rim outer wall, wherein said lid rim is located between said central region and said lid flange, wherein said lid flange extends in a plane substantially parallel with said container flange, wherein said lid flange includes a dimple for facilitating hot air penetration between said lid flange and said container flange;
- and
- c. providing hot air and welding said lid flange to said container flange at said dimple.
A method of fabricating a package, comprising:
- a. providing a lid, and providing said lid with a central planar region and a lid rim wherein said lid rim includes a lid rim inner wall, a lid rim outer wall, a tab, and a lid flange, wherein said tab extends in a plane parallel to said central planar region, wherein said tab extends outside said lid rim outer wall, wherein said lid flange extends in a plane parallel to said central planar region, wherein said lid flange extends outside said lid rim outer wall;
- and
- b. partially cutting a region on said lid rim outer wall, wherein said partially cutting includes at least one laser treating from the group consisting of laser scribing, laser cutting, and laser slitting, wherein said partially cutting provides a partially cut region extending around most of said lid rim outer wall, wherein said tab is located for providing for pull-separating along said partially cut region when said tab is pulled.
