Abstract
Abstract A new and improved exit slit for extracting a web from bulk moist tissue-like material from a container therefor, the tissuelike material being perforated at spaced intervals for severing at the slit as it is dispensed through the slit. The slit is substantially closed but has yielding edge portions imparting drag on the web to enable severing thereof into separate sheets as the web is pulled from the container, the slit being located at an angle with respect to the plane of the surface of the container in which the slit is located. This slit may be crossed or it may be single and straight; or a single V-shaped slit may be used.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
73 words
The combination with an enclosed substantially airtight container having an opening therein, of an elongated web of impregnated absorbent material in the container, a cap for closing the container, said cap including a top, a portion of said top being relatively inclined with respect to the major portion of the top, and there being a web exit slit in said inclined top portion, the web being adapted to be pulled through said slit.
Claim 2
Dependent Claim
73 words
The combination with an enclosed substantially airtight container having an opening therein, of an elongated web of impregnated absorbent material in the container, a cap for closing the container, said cap including a top, a portion of said top being relatively inclined with respect to the major portion of the top, and there being a web exit slit in said inclined top portion, the web being adapted to be pulled through said slit.
Claim 3
Dependent Claim
12 words
The combination of claim 1 wherein said slit is a single slit.
Claim 4
Dependent Claim
12 words
The combination of claim 1 wherein said slit is a cross slit.
Claim 5
Dependent Claim
39 words
The combination of claim 1 including another top portion which is in turn inclined with respect to the first inclined portion, the slit being in the form of a V extending from a common point along the inclined portions.
Claim 6
Dependent Claim
17 words
The combination of claim 1 wherein the inclined top portion is in the form of a cone.
Claim 7
Dependent Claim
32 words
The combination of claim 1 wherein the inclined top portion is in the form of a cone and the slit is a straight slit directly across the cone including the apex thereof.
Claim 8
Dependent Claim
18 words
The combination of claim 1 wherein the inclined top portion is in the form of an inclined plane.
Claim 9
Dependent Claim
18 words
The combination of claim 7 wherein the slit is also inclined relative to the top of the cap.
Claim 10
Dependent Claim
38 words
The combination of claim 1 wherein said inclined top portion is in the form of a cone, and a second slit crossed with respect to the first named slit, said slits intersecting adjacent the apex of the cone.
Claim 11
Dependent Claim
96 words
The combination with an enclosed substantially air-tight container with an elongated web of moist impregnated absorbent material therein, means forming a slit in a wall of the container, the material of said wall being substantially resilient and self sustaining, the web of absorbent material being capable of extraction from the container by being pulled out through the slit, the wall of the container including the slit having a portion at an inclination with respect to the general surface of said wall, the slit being at an inclination with respect to the general surface of said wall.
Claim 12
Dependent Claim
96 words
The combination with an enclosed substantially air-tight container with an elongated web of moist impregnated absorbent material therein, means forming a slit in a wall of the container, the material of said wall being substantially resilient and self sustaining, the web of absorbent material being capable of extraction from the container by being pulled out through the slit, the wall of the container including the slit having a portion at an inclination with respect to the general surface of said wall, the slit being at an inclination with respect to the general surface of said wall.
Claim 13
Dependent Claim
89 words
The combination of claim 10 wherein said slit has edges in substantial contact with each other, the inclined portion of said wall containing the edges of the slit being yieldable allowing extraction of the absorbent material, the edges of the slit tending to resist withdrawal of the web, the web being weakened at intervals and disrupting at these intervals under the tensions of the withdrawal pull against the relatively inclined slit, the latter being inclined relative to the direction of the pull on the web in the dispensing thereof.
Claim 14
Dependent Claim
12 words
The combination of claim 10 wherein the cap is removable and replaceable.
Claim 15
Dependent Claim
17 words
The combination of claim 10 wherein the portion of the wall containing the slit is generally flat.
Claim 16
Dependent Claim
10 words
The combination of claim 13 wherein the slit is single.
Claim 17
Dependent Claim
17 words
The combination of claim 10 wherein the portion of the wall containing the slit is generally conical.
Claim 18
Dependent Claim
14 words
The combination of claim 15 including a second slit crossing the first named slit.
Claim 19
Dependent Claim
18 words
The combination of claim 16 and the crossed slits intersect at the apex of the conical wall portion.
