Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
121 words
Closure-applying apparatus comprising: a. positioning means for positioning a film over an open-ended container to be closed; b. shearing and retaining means in combination for shearing said film and for retaining the sheared film in contact with said shearing means, said shearing and retaining means being movably positionable to bring the sheared film into contact with the open end of said container; c. clamping means actuated in conjunction with said shearing and retaining means to hold said film in position during shearing; d. forming means for detaching said sheared film from said shearing means and for forming said sheared film in closing relationship with said container to close said container; and, e. means for removing the closed container from said apparatus.
Claim 2
Dependent Claim
121 words
Closure-applying apparatus comprising: a. positioning means for positioning a film over an open-ended container to be closed; b. shearing and retaining means in combination for shearing said film and for retaining the sheared film in contact with said shearing means, said shearing and retaining means being movably positionable to bring the sheared film into contact with the open end of said container; c. clamping means actuated in conjunction with said shearing and retaining means to hold said film in position during shearing; d. forming means for detaching said sheared film from said shearing means and for forming said sheared film in closing relationship with said container to close said container; and, e. means for removing the closed container from said apparatus.
Claim 3
Dependent Claim
