## Abstract

A cutting assembly is provided that is adapted for use in combination with a container for dispensing a web of material. The dispensing container includes a plurality of adjoining sidewalls which define an external geometric profile. The cutting assembly includes a guide disposed in combination with a sidewall of the container and a cutter adapted for traversing within the elongate guide in a desired cutting direction. Furthermore, guide and bearing surfaces, formed on the guide and cutter, respectively, cooperate to permit sliding motion therebetween in the cutting direction and interlock to delimit displacement of the cutter relative to the guide in directions orthogonal to the cutting direction. A portion of the guide and cutter is disposed proximal to a corner of the container and recessed relative to its external geometric profile to facilitate container storage and display while additionally producing an aesthetically pleasing appearance. The cutting assembly may also be adapted to structurally augment the corner of the container to obviate structural flaws which may develop due to loads imposed by the cutting assembly on the container.

## Claims

### Claim 1

A cutting assembly in combination with a container for dispensing a web of material from a roll of the web, the roll having a longitudinal axis about which the web is wound, said container having a plurality of adjoining sidewalls extending parallel to the longitudinal axis and serially joined together at respective longitudinal edges of the sidewalls to form corners of the container, the sidewalls defining an external geometric profile of the container, a slot being defined in one of said sidewalls for leading the web out of an interior of the container through the slot, the cutting assembly comprising:
a guide disposed within a sidewall of the container proximate one of the corners formed between adjoining sidewalls, the guide defining at least one guide surface, the guide further including a portion disposed against an outer side of the sidewall and defining a surface facing outwardly away from the interior of the container on which the web led out through the slot is laid for cutting of the web, the guide further comprising a strengthening member extending from said guide to said corner and engaging surfaces of said adjoining sidewalls to structurally reinforce said corner; and
a cutter for traversing within said guide in a desired cutting direction, and defining at least one bearing surface,
said guide and bearing surfaces cooperating to permit sliding motion therebetween in said cutting direction and interlocking to delimit motion of said cutter relative to said guide in directions orthogonal to said cutting direction,
at least 50% of the cutting assembly being disposed internally of the external geometric profile of the container.

### Claim 2 (depends on 1)

The cutting assembly according to claim 1 wherein said strengthening member is integrally formed in combination with said guide.

### Claim 3 (depends on 2)

The cutting assembly according to claim 2 wherein said strengthening member has a substantially L-shaped cross sectional configuration and engages the interior surfaces of said adjoining sidewalls.

### Claim 4 (depends on 1)

The cutting assembly according to claim 1 wherein said guide and bearing surfaces define a substantially inverted T-shaped cross sectional configuration.

### Claim 5 (depends on 1)

The cutting assembly according to claim 1 wherein said cutter defines cutting edges on oppositely disposed edges thereof.
