## Abstract

A spray tip for an aerosol can has two pairs of flexible and resilient wings which extend outwardly from opposite sides of a spraying orifice in the tip. The wings cooperate with inclined surfaces in the bottom wall of a can holder in a spraying apparatus to orient the spray tip so that the spraying orifice is properly aligned with respect to the direction in which the spraying apparatus is moved. The wings can also cooperate with a sliding actuating bar which will engage the wings and align the spray tip.

## Claims

### Claim 1

In a spraying apparatus having an aerosol can holder, and an aerosol can mounted in the can holder, the can holder having a bottom wall for supporting the aerosol can, the improvement comprising a spray tip mounted on the aerosol can, the spray tip having a spraying portion having a rectangular spraying orifice and wing portions extending from the spraying portion generally parallel to the long dimension of the spraying orifice, the bottom wall of the can holder having an opening through which the contents of the aerosol can can be sprayed, a pair of inclined surfaces diverging outwardly and upwardly from the opening, each of the inclined surfaces extending in a plane which is generally parallel to a line which extends perpendicularly to the direction in which the spraying apparatus is rolled, and a pair of aligning blocks on the bottom wall between the inclined surfaces, the aligning blocks being sized and arranged to position the wing portions and the long dimension of the spraying orifice generally perpendicular to the direction in which the spraying apparatus is moved.

### Claim 2 (depends on 1)

The structure of claim 1 in which the spray tip includes a pair of wing portions extending from the spraying portion on opposite sides of the spraying orifice, the aligning blocks being positioned between the pairs of wing portions when the long dimension of the spraying orifice is perpendicular to the direction in which the spraying apparatus is moved.

### Claim 3 (depends on 1)

The structure of claim 1 in which each of the aligning blocks has an upper surface which slants downwardly as it extends away from the opening in the bottom wall.

### Claim 4 (depends on 1)

The structure of claim 1 in which each of the aligning blocks has an inverted V-shaped upper surface and an upper edge which slants downwardly as it extends away from the opening in the bottom wall.

### Claim 5 (depends on 4)

The structure of claim 4 in which the wing portions are flexible and resilient.

### Claim 6 (depends on 2)

The structure of claim 2 in which the wing portions are flexible and resilient.

### Claim 7 (depends on 2)

The structure of claim 2 in which the spray tip is molded from flexible and resilient material whereby the wing portions are flexible and resilient.

### Claim 8

A spray tip for an aerosol can comprising a spraying portion having a spraying orifice and two pairs of spaced-apart wing portions, each pair extending from the spraying portion on opposite sides of the spraying orifice whereby the spray tip has a generally H-shaped configuration in a plane perpendicular to the spraying orifice.

### Claim 9 (depends on 8)

The spray tip of claim 8 in which the spraying orifice is generally rectangular and has a long dimension which extends generally parallel to the wing portions.

### Claim 10 (depends on 8)

The spray tip of claim 8 in which the spray tip is molded from flexible and resilient material whereby the wing portions are flexible and resilient.
