Definitions

  • the invention relates to a method of coating glass containers, and more particularly to a technique for applying colour coatings that singularly or together may be coloured, block ultra-violet light, and offer a range of surface textures.
  • the glass container industry limits itself to three primary colours for containers; clear glass (commonly called flint glass), amber and green.
  • the green and amber are melted in several hues for both product differentiation and protection of the contents from the adverse effects of transmitted visual light as well as the ultra-violet component of natural and artificial light.
  • Significant cost resulting from lost production when a glass melting unit changes from one colour to another is experienced throughout the industry as well as the cost to carry inventory of containers made of a specific color during a run of a few weeks that will satisfy many months of need.
  • extra fuel is required to melt colored glass batch.
  • the melting furnace life is reduced by the corrosive action of colored glass batches.
  • Patent Abstracts of Japan, Vol. 12, No. 382 discloses the painting of a bottle surface for shielding ultra-violet rays following a method according to the preambles of claims 1 and 13.
  • World Patent Index Latest, Week 8644, Derwent Publications Ltd., London, GB, AN 86-28759 discloses a UV shielding covering composition for glass.
  • Yet another aim of this invention is to foster continued further reduction in container weight.
  • the present invention provides a method of coating a glass container, comprising the steps of: providing a container of glass, said glass having an inside surface directed toward an interior of said container and an outer surface directed toward an exterior of said container; annealing said glass container; coating said container with at least a final acrylic coating layer applied in liquid form; and curing said acrylic coating; said method being characterized by the steps of applying a first coating material to said container at a first location in a container fabrication line subsequent to said annealing step; conveying said container to a second location with said first coating material providing surface lubricity; and applying an acrylic coating layer which is compatible with said first coating material over said glass on said outer surface of said container while at least some of said first coating material remains on said outer surface, said acrylic coating layer having a cured thickness of no greater than 0.0152 mm (0.0006 inch).
  • the present invention further provides a method of coating a glass container, comprising the steps of: providing a container of glass, said glass having an inside surface directed toward an interior of said container and an outer surface directed toward an exterior of said container; annealing said glass container; coating said glass container with at least a final acrylic coating layer applied in liquid form; and curing said acrylic coating; said method being characterized by the steps of applying a first coating material to said container at a first location in a container fabrication line subsequent to said annealing step; conveying said container to a second location with said first coating material providing surface lubricity; exposing said first coating material to an oxidizing flame whereby first coating material is burnt off; and applying an acrylic coating layer over said glass on said outer surface of said container subsequent to said oxidizing flame step, said acrylic coating layer having a cured thickness of no greater than 0.0152 mm (0.0006 inch).
  • the aims and advantages of the invention are achieved by coating the glass containers with a material, preferably heat-curable or UV-curable acrylic, which provides impact resistance and durability, such that it is no longer necessary to provide the tin oxide film prior to container lehring.
  • the coating material is selected to have a colour corresponding to the desired container colour, and/or can be selected to have a composition which will block certain wavelengths of light which are considered harmful to the contents of the bottle.
  • the coating material also provides sufficient impact and abrasion resistance to permit the tin oxide film to be dispensed with, with merely a token amount of the lubricating film being applied after annealing.
  • This lubricating film is one which is compatible with the coating, such as ammonium stearate.
  • the lubicating flim is sufficient to enable damage-free conveying from the lehr, through the inspection stations and into the colour coat machine staging area.
  • the present invention resides in applying to a clear glass container a coating which may have a number of properties. There are a great number of properties which may be considered significant in any given case, but the properties discussed herein are color, light blocking for protection of the container contents from irradiation, abrasion resistance and impact resistance.
  • the coating material is preferably a urethane coating, with appropriate additives as will be described below.
  • the first significant property of the coating material is the color.
  • it is sometimes desirable to color the bottle e.g., to amber or green, and this has heretofore been achieved by specific formulation of the glass batch introduced into the melters.
  • an acrylic coating e.g., urethane
  • heat-curable or UV-curable could be made to provide the desired coloring of the container.
  • the coloring technique would provide any color desired to suit the particular product, from light tints to fully opaque colors.
  • the particular additives to be used for this purpose would depend on the colors desired, with a number of suitable organic dyes being well-known to those of skill in the art.
  • the cured color coat is formulated to withstand the wash and pasteurization processes associated with non-returnable containers, and with chemical modifications to the color coat, returnable containers will be able to survive the alkali wash required prior to refilling. Nor will the color coat be adversely affected by water, alcohol or organic materials used in the filling operations.
  • the color coatings on adjacent containers will not abrade each other during the filling and packaging operations associated with transport, store display and consumer purchasing, and the color coat will also be chemically and physically stable.
  • a preferred technique for providing irradiation protection for the container contents is to determine, e.g., via spectrographic analysis, which wavelengths of light are absorbed by the container contents, and to then include additives in the topcoat which will block light in these regions.
  • the additives to be used would be known to those of skill in the art after determining the wavelengths of light to be blocked.
  • the damaging ultra-violet component may be largely blocked by a clear additive, either to a clear or colored coating.
  • Variations in color coating texture and appearance may also be desirable. It has been demonstrated that with changes in coating composition the surface may be altered from gloss finish, to matte, to frosted. This is done without sacrificing physical properties.
  • a further aim of the invention to eliminate the cost of tin oxide coating. Because the acrylic coating of this invention provides impact resistance and durability, it is no longer necessary to provide the tin oxide film prior to container lehring.
  • a lubricating film is sufficient to enable damage-free conveying from the lehr, through the inspection stations and into the color coat machine staging area. It should be a lubricating film compatible with the coating, such as ammonium stearate.
  • ammonium stearate is comaptible with the coating material and allows the bonding of the coating to the glass so that burning off of residual lubricant may not be necessary.
  • a coupling agent to promote adhesion of the color coat material to the container surface to meet certain container processing and use requirements, specifically, but not limited to the typical beer industry pasteurization process. While the coupling agent can be mixed with the color coat before application, it may be desirable to apply the coupling agent to the container surface before the color coat is applied for economic reasons as well as technical reasons.
  • the containers are conveyed into a multi-station spray system which has been designed to address the needs of uniform coverage of the container and recovery of the overspray.
  • the gripper devices are attached to a conveyor network whose design allows for spacing of the glass containers to optimize the coating and curing of the coating materials.
  • the grippers should also be designed for rotating the container at the spraying and curing positions to insure uniform coating and processing.
  • the application of the coating solution could be accomplished by belt or roller coating as described in WO-A-90/05088.
  • Alternative methods of applying the topcoat include, but are not limited to, the use of a roller shaped to conform to the contour of the container, a belt flexible enough to conform to the container contour, or flowing the coating over the container while it is slowly rotated. Dipping may also be advantageous. Each option has its own merits and must be weighed against economics, quality and production rates.
  • the containers are then conveyed to a circulating hot air cure chamber designed to provide the necessary exposure to hot air to completely cure the topcoat. It has been demonstrated that air moving at 457.2 m (1500 feet) per minute and at a temperature of 287.8°C (550°F) will insure a complete cure in 1.5 minutes.
  • the container can be packaged for shipment and subsequent wash, filling and pasteurization, if required, by the various food and beverage packaging operations.
  • the single figure herein illustrates one example of a system for applying the coating of this invention.
  • the coating with ammonium stearate would be performed before the bottles are received at the upper right of the figure along a conveyor 100.
  • the bottles would then be transferred to a loading station 104 one at a time by a star wheel control device 102.
  • the bottles are then moved downwardly onto an indexing table 106 by means of a suitable placement device.
  • the indexing table 106 will include container holders, e.g., suction holders or the like, and there may be supports at the neck of each container to absorb pressure during the container transfer.
  • the indexing table is then rotated counterclockwise from the loading station to a container orienting station generally designated at reference character 108.
  • the container may here be rotated to a particular orientation, although this will be unnecessary in many container systems.
  • the rotating of the container would preferably be performed by rotation of individual container holder suction cups on the indexing table 106 until the correct position is detected, e.g., by suitable photo-electric means, at which point the holders would be locked in their correct positions.
  • the indexing table 106 is further rotated to bring the bottles to the coating station 114 where the coating of this invention is applied.
  • the indexing table 106 is then further rotated to bring the coated bottles to an unloading station where each container is off-loaded onto a container conveyor.
  • the bottles could be removed. All bottles could be removed from the indexing table 106 to a single conveyor 120, taking care to ensure that the coatings are not disturbed. It may, be necessary, with suitable care taken, to use an air knife. It may, however, be necessary to move the bottles by clamping them at their "finish" and carrying them onto the conveyor 120 in a known manner.
  • the bottles are held in groups of three on the indexing table 106.
  • the coating on the bottles is cured in a suitable manner, e.g., by heat in the case of heat-curable coating or by U-V energy in the case of UV-curable coating.
  • the conveyor 120 carries the bottles to a further container processing stage, e.g., labelling, inspection, packing and/or filling.
  • a topcoating material as described herein will impart a desired color to a bottle, will increase abrasion and impact resistance of the glass container, will be waterproof and unaffected by the contents of any food or beverage, will be glossy and will not be abraded by like material, and will cover flaws and irregularities on the surface of glass containers such as to render them nearly invisible.
  • the heat-curable color coating material can be cured quickly with hot convective air, easily achieved with commercial equipment. It is necessary to achieve a glass substrate temperature of 148.9°C (300°F) to achieve all of the desired properties of the color coat. Other curing processes are available.
