Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
137 words
A package for sewing machine needles or the like comprising a block of synthetic thermoplastic material formed by a first molding process with a plurality of elongated parallel sewing needle accommodating compartments opening on the same side of the block, each said compartments being bounded on both sides by a partition composed of thermoplastic material integral with that of said block, said compartments each being formed in the block deeper than the maximum diameter of the needles to be accommodated, and needle retaining lugs formed on said partitions so as to project into said needle accommodating compartments by a second molding process which deforms the thermoplastic material at the top of the partitions creating in each partition a localized recess of which the thermoplastic material is displaced into an adjoining compartment to form one of said lugs.
Claim 2
Dependent Claim
137 words
A package for sewing machine needles or the like comprising a block of synthetic thermoplastic material formed by a first molding process with a plurality of elongated parallel sewing needle accommodating compartments opening on the same side of the block, each said compartments being bounded on both sides by a partition composed of thermoplastic material integral with that of said block, said compartments each being formed in the block deeper than the maximum diameter of the needles to be accommodated, and needle retaining lugs formed on said partitions so as to project into said needle accommodating compartments by a second molding process which deforms the thermoplastic material at the top of the partitions creating in each partition a localized recess of which the thermoplastic material is displaced into an adjoining compartment to form one of said lugs.
Claim 3
Dependent Claim
58 words
A package for sewing needles or the like as set forth in claim 1 in which said localized recesses formed in said partitions by each second molding process reduce the height of said partitions at said localized recesses to a dimension substantially equal to that of the maximum diameter of the needles to be accommodated in said compartments.
Claim 4
Dependent Claim
47 words
A package for sewing needles or the like as set forth in claim 1 in which each needle retaining lug displaced from a partition into an adjoining compartment is formed in said second molding process with an outer surface which is inclined downwardly into said adjoining compartment.
Claim 5
Dependent Claim
60 words
A package for sewing needles or the like as set forth in claim 3 in which the bottom of each needle accommodating compartment beneath each needle retaining lug is formed in said first molding process with an oblique bearing surface inclined toward the center of said compartment facilitating centering of a needle retained in said compartment by said retaining lugs.
