Abstract
Abstract There is disclosed herein a bottle top cutter adapted and constructed to be utilized to cleanly horizontally sever the neck portion and above of a thermoplastic bottle which may contain a liquid. The apparatus is especially designed to sever a thermoplastic bottle which has a neck portion previously heat sealed into flat confrontation surfaces over a relatively narrow band area which is horizontally disposed or transverse to the longitudinal axis of the thermoplastic bottle. The apparatus comprises a holder for the cutting means and may possess aligning means for the bottle whereby the said heat sealed neck portion is in relative abutment to a fixed stationary means. The device possesses a movable blade which is positioned to move horizontally through suitable mechanical manually operated linkage means. The said manually operated linkage means is designed to move the blade horizontally in the direction of the stationary means whereby the thermoplastic bottle is severed in the said manner.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
127 words
An apparatus for severing the tip portion of a thermoplastic bottle along the flattened sides of the constricted neck portion of said bottle comprising at least two upright standards in spaced relationship from each other, a horizontal plate means affixed to one standard, a horizontal plate means affixed to the other standard, means for rigidly joining both said plate means and said standards, both of said plate means being in the same plane and in spaced relationship, said two plate means and said means for rigidly joining both plate means defining a space laterally enterable wherein the to-be-cut thermoplastic bottle is positioned, a movable cutting blade positioned on one of said plate means, means for moving said cutting blade towards said other plate means across said space.
Claim 2
Independent Claim
127 words
An apparatus for severing the tip portion of a thermoplastic bottle along the flattened sides of the constricted neck portion of said bottle comprising at least two upright standards in spaced relationship from each other, a horizontal plate means affixed to one standard, a horizontal plate means affixed to the other standard, means for rigidly joining both said plate means and said standards, both of said plate means being in the same plane and in spaced relationship, said two plate means and said means for rigidly joining both plate means defining a space laterally enterable wherein the to-be-cut thermoplastic bottle is positioned, a movable cutting blade positioned on one of said plate means, means for moving said cutting blade towards said other plate means across said space.
Claim 3
Dependent Claim
39 words
