Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
95 words
A container having improved frictional and handling characteristics in container handling apparatus, said container comprising an interior glass receptacle formed as a glass bottle and an exterior resinous plastic surface and a plurality of particles secured to said exterior plastic surface; said particles having exposed outwardly extending particle surfaces adapted to contact articles which touch said container, said particle surfaces further being hard and smooth relative to said container plastic surface so that friction will be reduced between said container and said articles due to contact of said hard smooth particle surface with said articles.
Claim 2
Dependent Claim
95 words
A container having improved frictional and handling characteristics in container handling apparatus, said container comprising an interior glass receptacle formed as a glass bottle and an exterior resinous plastic surface and a plurality of particles secured to said exterior plastic surface; said particles having exposed outwardly extending particle surfaces adapted to contact articles which touch said container, said particle surfaces further being hard and smooth relative to said container plastic surface so that friction will be reduced between said container and said articles due to contact of said hard smooth particle surface with said articles.
Claim 3
Dependent Claim
74 words
A container having improved frictional and handling characteristics in container handling apparatus, said container comprising an interior glass receptacle formed as a glass bottle and covered by a relatively soft resinous plastic coating, said glass receptacle being provided with protrusions which extend through said exterior plastic coating, said protrusions being adapted to contact articles which touch said container so that friction will be reduced between said container having said plastic coating and said articles.
Claim 4
Dependent Claim
74 words
A container having improved frictional and handling characteristics in container handling apparatus, said container comprising an interior glass receptacle formed as a glass bottle and covered by a relatively soft resinous plastic coating, said glass receptacle being provided with protrusions which extend through said exterior plastic coating, said protrusions being adapted to contact articles which touch said container so that friction will be reduced between said container having said plastic coating and said articles.
