DESCRIPTION:

BRIEF SUMMARY
FIELD OF INVENTION

This invention relates to a device for the long or short term preservation and storage of used paint brushes. More particularly the invention relates to a device for the long or short term preservation and storage of used, uncleaned paint brushes under conditions such that any residual paint remaining thereon does not dry or harden, and the bristles of the brush retain their shape and flexibility for a long period of time, so that the brush can be re-used straight away without cleaning or further treatment of any sort, and substantially without regard to the length of storage, whether for a few minutes, a few hours, days or even months.


BACKGROUND

As is well known, many decorators, especially amateur or nonprofessional decorators, tend not to pay sufficient attention to the care and preservation of their paint brushes following completion of a painting job and/or during intervals ranging perhaps from a few hours to one or more weeks between decorating sessions. Typically, amateur decorators tend, during such intervals, to leave their brushes soaking in white spirit with the result that the brushes dip into a slurry consisting of paint and white spirit and are in an unsatisfactory condition when painting is resumed. The bristles of such brushes then tend irreversibly to loose their pliability and/or their shape and hence have to be discharged and replaced long before such replacement should be necessary owing to fair wear and tear. Even professional decorators frequently merely leave their brushes soaking in a bucket of water over-night and such treatment tends to damage the brushes if not through hardening then at least through deformation.


PRIOR ART

In the past various proposals have been made for paint brush storage devices, either as a means to protect and store new brushes, or to protect and store paint brushes after use, and including in some cases a liquid brush cleaning or preserving component. Amongst such prior art devices there may be mentioned:
U.S. Pat. No. 1,934,316 which discloses a brush protecting device consisting of a wedge shaped sleeve designed to fit over the bristles of the brush to preserve the wedge shaped configuration and prevent paint thereon from drying out. No mention is made of any brush cleaning or preserving liquid.
U.S. Pat. No. 2,485,068 which discloses an open ended elastic sleeve into which the brush can be inserted and the end of the sleeve turned up to seal the bristles in an air-tight environment. The sleeve is open at both ends and cannot contain any brush preserving or cleaning liquid.
U.S. Pat. No. 2,533,829 which discloses a storage bag for paint brushes in the form of an envelope or bag open at one end and into which the head of the paint brush can be inserted after use. Means are provided for tying the open end of the bag tightly around the brush handle to prevent ingress of air and thereby to provide a substantially air-tight environment for the brush head which prevents drying out and hardening of any residual paint thereon. Alternatively it is suggested that the user may place some linseed oil or thinner into the bag prior to insertion of the brush into the bag.
U.S. Pat. No. 2,776,050 which discloses a water-tight bag and a wire stand therefor, and which can be used to suspend a paint brush after use with its head immersed in a brush cleaning liquid, the nature of which is not specified.
U.S. Pat. No. 3,167,178 which discloses an envelope into which the head of a paint brush can be inserted, and then used to suspend the brush from a suitable hook or nail. No liquid is used.
U.S. Pat. No. 3,690,448 which discloses a sealable plastics bag into which the whole paint brush can be placed and sealed, optionally after wrapping the bristles in a plastics wrapper and sealed with a rubber band.
U.S. Pat. No. 4,606,456 which discloses a prescored foldable cardboard or plastics wrapper which can be used to package paint brushes of different sizes.
