Abstract

Abstract An apparatus for coating a glass container with a layer of plastic whereby the container rotates about a horizontal axis and moves past a coating station. A plurality of liquid applicator nozzle means, positioned above the coating station, supply uncured plastic liquid to associated areas on the container. Means are provided for supplying predetermined quantities of uncured plastic liquid to respective ones of the nozzle means such that each nozzle means provides a coating of desired thickness and composition on its associated bottle area. The container is also rotated during the subsequent curing of the plastic.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 143 words
Apparatus for coating a glass container with a layer of plastic comprising: means for rotating a glass container about a horizontal axis and moving said container past a coating station, a plurality of liquid applicator nozzle means, positioned above the coating station, each of said nozzle means, including a plurality of fluid carrying tubes distributed axially along said container, for supplying uncured plastic liquid to an associated area on the container as the container rotates, means for supplying predetermined quantities of uncured plastic liquid to respective ones of said plurality of nozzle means, and means for rotating said container about a horizontal axis after uncured liquid plastic is applied to said container at said coating station such that said container is rotated as said plastic cures, whereby each of said nozzle means provides a coating of desired thickness on its associated container area.
Claim 2
Dependent Claim 143 words
Apparatus for coating a glass container with a layer of plastic comprising: means for rotating a glass container about a horizontal axis and moving said container past a coating station, a plurality of liquid applicator nozzle means, positioned above the coating station, each of said nozzle means, including a plurality of fluid carrying tubes distributed axially along said container, for supplying uncured plastic liquid to an associated area on the container as the container rotates, means for supplying predetermined quantities of uncured plastic liquid to respective ones of said plurality of nozzle means, and means for rotating said container about a horizontal axis after uncured liquid plastic is applied to said container at said coating station such that said container is rotated as said plastic cures, whereby each of said nozzle means provides a coating of desired thickness on its associated container area.
Claim 3
Dependent Claim 49 words
The apparatus of claim 1 further comprising means for moving said plurality of nozzle means parallel to the direction of movement of the container past the coating station such that said plurality of nozzle means are positioned above the bottle for at least an entire rotation of the container.
Claim 4
Dependent Claim 53 words
The apparatus of claim 2 in which said means for moving said plurality of nozzle means includes means to move said plurality of nozzle means parallel to the direction of container movement for a predetermined period of time after said nozzle means terminates coating, such that said nozzle means may be drained completely.
Claim 5
Dependent Claim 103 words
The apparatus of claim 1 in which said plastic liquid material is produced by mixing two constituent materials and in which said means for supplying such fluid comprises: a mixing device for mixing the two constituent materials, a plurality of pairs of metered pump means for pumping the constituent materials to said mixing device, a source of hydraulic fluid, and a plurality of hydraulic motor means connected to said source of hydraulic fluid, each of said motor means operatively connected to an associated pair of pump means such that the proper proportions of constituent plastic materials will be pumped to said mixing device.
Claim 6
Dependent Claim 26 words
The apparatus of claim 1 further comprising means for pumping a solvent through said plurality of nozzle means such that said nozzle means may be cleaned.
Claim 7
Dependent Claim 38 words
The apparatus of claim 1 further comprising means for irradiating each container with infrared radiation subsequent to the application of plastic fluid to the container as said container continues to rotate such that the container coating is cured.
