Abstract
Plastics material packaging includes a receptacle having a bottom and a sidewall which present an annular rim around its edge remote from the bottom, said rim providing an area for sealing a closure membrane, and the packaging further includes a cover applied to the receptacle over said membrane which it encloses. The cover is secured to the receptacle by a permanent connection that can be disconnected when the packaging is opened only by being broken, which connection is advantageously constituted by a discrete number of breakable tampering indicators. The invention also provides a method of manufacturing such packaging for long-term storage of food.
Claims10
A reclosable four-part plastics material packaging comprising:
- a receptacle having a bottom and a sidewall including an annular rim around an edge remote from the bottom, said rim having a top face, a bottom face and an outward face;
- a skirt secured to said bottom face of said rim and comprising a first sidewall extending outwardly and downwardly from said rim and having a first peripheral edge, said skirt including breakable skirt lugs protecting outwardly from said first peripheral edge;
- a substantially flat closure membrane sealed on a top face of said rim;
- and
- a cover applied to the receptacle over said membrane and said skirt, the cover enclosing the membrane and including a disk, a second sidewall extending outwardly and downwardly from said disk and having a second peripheral edge, said second sidewall having substantially the same shape as said first sidewall, and breakable cover lugs protecting outwardly from said second peripheral edge, wherein the skirt lugs and the cover lugs are secured to one another and wherein the cover is secured to the skirt only by said skirt breakable lugs and said cover breakable lugs, said lugs forming tampering indicators for the opening of the cover when the lugs are broken off from the cover, further comprising spacing means for keeping the cover at a distance from the skirt during assembly so as to create chimney gaps.

A reclosable four-part plastics material packaging comprising:
- a receptacle having a bottom and a sidewall including an annular rim around an edge remote from the bottom, said rim having a top face, a bottom face and an outward face;
- a skirt secured to said bottom face of said rim and comprising a first sidewall extending outwardly and downwardly from said rim and having a first peripheral edge, said skirt including breakable skirt lugs projecting outwardly from said first peripheral edge;
- a substantially flat closure membrane sealed on a top face of said rim;
- and
- a cover applied to the receptacle over said membrane and said skirt, the cover enclosing the membrane and including a disk, a second sidewall extending outwardly and downwardly from said disk and having a second peripheral edge, said second sidewall having substantially the same shape as said first sidewall, and breakable cover lugs projecting outwardly from said second peripheral edge, wherein the skirt lugs and the cover lugs are secured to one another and wherein the cover is secured to the skirt only by said skirt breakable lugs and said cover breakable lugs, said lugs forming tampering indicators for the opening of the cover when the lugs are broken off from the cover.
