Abstract
Abstract A dispenser for a treated perforated tissue web wherein said dispenser is provided with an opening for extraction of the web from the dispenser, said opening having associated therewith an interior flap which normally all but closes the opening through which the web is withdrawn thereby providing sufficient tension on the web to cause it to tear off at the perforations. A variation includes a form in which the flap is such that it completely closes and overlaps the opening in the dispenser forcing the web to travel in a tortuous path.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
131 words
A dispenser for a web of perforated tissue-like material comprising a container including a wall, an opening in the wall, said opening including a fixed edge portion, means within the container normally substantially closing said opening, the web passing through the opening between the edge portion and the closing means, the edge portion and the closing means applying friction to the web to apply tension to the web as it is pulled from the container, the tension causing the web to separate at the perforations leaving a leading tip exposed exteriorly of the container, said edge portion overlying the closing means and preventing motion of the latter past the edge portion, said closing means being movable to uncover the opening, providing for easy initiation of the passage of the web therethrough.
Claim 2
Dependent Claim
131 words
A dispenser for a web of perforated tissue-like material comprising a container including a wall, an opening in the wall, said opening including a fixed edge portion, means within the container normally substantially closing said opening, the web passing through the opening between the edge portion and the closing means, the edge portion and the closing means applying friction to the web to apply tension to the web as it is pulled from the container, the tension causing the web to separate at the perforations leaving a leading tip exposed exteriorly of the container, said edge portion overlying the closing means and preventing motion of the latter past the edge portion, said closing means being movable to uncover the opening, providing for easy initiation of the passage of the web therethrough.
Claim 3
Dependent Claim
12 words
The dispenser of claim 1 wherein said closing means is a flap.
Claim 4
Dependent Claim
21 words
The dispenser of claim 2 including a hinge for the flap, said hinge being on the container wall adjacent the opening.
Claim 5
Dependent Claim
26 words
The dispenser of claim 1 wherein said means comprises a flap and including means for releasably holding the flap in its position substantially covering the opening.
Claim 6
Dependent Claim
27 words
The dispenser of claim 1 wherein said means completely covers the opening, but allows passage of the web between the opening covering means and the fixed edge.
Claim 7
Dependent Claim
23 words
The dispenser of claim 1 wherein said means for closing the opening closes it except for a relatively small passage for the web.
Claim 8
Dependent Claim
37 words
The dispenser of claim 1 wherein said means comprises a flap which when in its closed position completely covers and overlaps the opening whereby the web must pass through a tortuous path in order to be extracted.
Claim 9
Dependent Claim
111 words
The combination with an enclosed container having an opening therein, a cap closing the opening in the container, the cap including a substantially rigid top, an edged opening in said top, and movable means within the container substantially covering said opening, but being movable to uncover the opening, means holding the said movable means closely to an edge of the opening, of a web in the container, said web being grasped between said movable means and an edge of the opening applying friction to the web thereby resisting extraction of the web from the container under tension imparted to the web by manually pulling on an exposed tip of the web.
Claim 10
Dependent Claim
111 words
The combination with an enclosed container having an opening therein, a cap closing the opening in the container, the cap including a substantially rigid top, an edged opening in said top, and movable means within the container substantially covering said opening, but being movable to uncover the opening, means holding the said movable means closely to an edge of the opening, of a web in the container, said web being grasped between said movable means and an edge of the opening applying friction to the web thereby resisting extraction of the web from the container under tension imparted to the web by manually pulling on an exposed tip of the web.
Claim 11
Dependent Claim
28 words
The combination of claim 8 wherein said means is a flap hinged to the cap adjacent the opening, said flap being capable of hinging to uncover the opening.
Claim 12
Dependent Claim
32 words
The combination of claim 9 wherein said means in one position completely covers the opening but allows passage of the web between the opening closing means and the edge of the opening.
Claim 13
Dependent Claim
24 words
The combination of claim 8 wherein said means completely closes the opening except for a small passage through which the web passes under friction.
Claim 14
Dependent Claim
55 words
The combination of claim 8 wherein said means comprises a flap, means hinging the flap closely adjacent the opening, the flap being openable to provide for pushing the leading end of the web through the opening, and means holding the flap substantially in closed position relative to the opening and applying friction to the web.
Claim 15
Dependent Claim
201 words
A dispenser for a web of tissue-like material having spaced perforations along the same, said dispenser comprising a container having an open end therein, the container being otherwise closed, a removable cap closing the open end of said container, said cap having a top with an opening therein, said opening having a substantially fixed edge, a depending flap hinged to the top of said cap at the underside thereof adjacent the opening, means to hold the flap in a position to close the opening, the flap retreating from the opening when released from the flap holding means, the flap when clOsing the opening leaving a small passage for the web to be drawn out of the container, through the passage, said passage being located between the fixed edge of the opening and an edge of the flap, the edge of the flap and the edge of the opening grasping the web and applying friction thereto as it is being drawn out of the container, causing the web to disrupt at intervals at said perforations leaving a leading tip of the web extending through the opening in the top of the cap for manual grasping thereof to withdraw the web another length.
Claim 16
Dependent Claim
201 words
A dispenser for a web of tissue-like material having spaced perforations along the same, said dispenser comprising a container having an open end therein, the container being otherwise closed, a removable cap closing the open end of said container, said cap having a top with an opening therein, said opening having a substantially fixed edge, a depending flap hinged to the top of said cap at the underside thereof adjacent the opening, means to hold the flap in a position to close the opening, the flap retreating from the opening when released from the flap holding means, the flap when clOsing the opening leaving a small passage for the web to be drawn out of the container, through the passage, said passage being located between the fixed edge of the opening and an edge of the flap, the edge of the flap and the edge of the opening grasping the web and applying friction thereto as it is being drawn out of the container, causing the web to disrupt at intervals at said perforations leaving a leading tip of the web extending through the opening in the top of the cap for manual grasping thereof to withdraw the web another length.
Claim 17
Dependent Claim
34 words
The dispenser of claim 13 wherein the flap flatly contacts the underside of the top of the cap and covers the entire opening in the top of the cap except for the small passage.
Claim 18
Dependent Claim
42 words
The dispenser of claim 13 wherein said flap completely overlaps the opening at the top of the cap but remains in slightly spaced relation with respect to the underside of the top of the cap leaving the small passage for the web.
