Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 66 words
1 . A biaxially oriented container (1) having three layers (4,5,4) in section obtained by concentrically injecting two kinds of plastics into a cavity to mold a bottomed parison and stretch-blow molding said parison, characterized in that an intermediate layer (5) of said container is formed of plastic containing the desired length of glass fiber (6) whereby said container has excellent heat-resistance and gas barrier properties.
Claim 2
Dependent Claim 66 words
1 . A biaxially oriented container (1) having three layers (4,5,4) in section obtained by concentrically injecting two kinds of plastics into a cavity to mold a bottomed parison and stretch-blow molding said parison, characterized in that an intermediate layer (5) of said container is formed of plastic containing the desired length of glass fiber (6) whereby said container has excellent heat-resistance and gas barrier properties.
Claim 3
Dependent Claim 53 words
A biaxially oriented container (1) with excellent heat-resistance and gas barrier properties as defined in Claim 1 in which said glass fiber (6) has a length of 1 - 4 mm and is contained in a percentage of 0.5 - 3.0 weight % with respect to plastic which forms the intermediate layer (5).
Claim 4
Dependent Claim 34 words
A biaxially oriented container (1) with excellent heat-resistance and gas barrier properties as defined in Claim 1 in which the plastic for forming said intermediate layer (5) comprises plastic with excellent gas barrier properties.
Claim 5
Dependent Claim 42 words
A biaxially oriented container (1) with excellent heat-resistance and gas barrier properties as defined in Claim 1 in which said intermediate layer (5) consists of plastic material selected from the group consisting polyethylene terephthalate, saponified ethylene-vinylacetate copolymer, ethylene-vinylalcohol copolymer, and m-xylene-type polyamide.
