Abstract
Adhesive applicators having a flexible valve disk which defines a metering chamber with a valve body, the valve body with the valve is insertable into a can component in close confinement thereby and the valve is operated by flexing the disk to compress the adhesive and spurt it against the confining surface of the can body to form a bead and band of adhesive into which the other can component is subsequently telescoped.
Claims5
A mechanism for applying adhesive to the interior of an axially extending surface of a can component comprising:
- a valve body having a lower end with concave cavity bounded by a sharp peripheral edge,
- a flexible valve plate aligned with said end of said body having a peripheral lip disposed in closing relation to said edge,
- said plate and body defining a metering chamber, inlet means in said body communicating with said chamber,
- means for providing a source of flowable adhesive to flow through said inlet means into said chamber, and
- means for flexing said plate for said adhesive into said metering chamber and for compressing the adhesive within said chamber to exhaust the adhesive from between said edge and lip radially onto said surface.
