The invention relates to a packaged stipple brush and its method of construction. The stipple brush is constructed of brush receptacles retaining brush elements for transferring a generally radial pattern to topping compound applied to a surface. The brush receptacles are acutely angled with respect to the centerline of the brush which predisposes the brush elements to lie in a flattened manner, thus eliminating the need for the craftsman or other user to train the stipple brush prior to its use. The brush elements are further trained to lie flat by the method in which a fully assembled brush is removably captively retained against a flat surface, such as a point of sale display, during it shipping, storage, and display. In this manner the package becomes part of the manufacturing process for the stipple brush. The brush of the present invention also is unique in that the brush elements are arranged in predefined patterns which produce pleasing and consistent ceiling patterns when the lengthwise extent of the brush elements contact wet stipple or topping medium.

Packaging for packaging of products under a transparent film, a process for performing this packaging and a device for using this process. The packaging comprises a plate of cardboard or the like intended for supporting at least one product to be packaged, whose face receiving the product or products receives a coating of a layer of synthetic material, a first sheet of synthetic material for covering the upper face of the plate and the product or products resting on it. The first sheet is attached to the plate by being heated and partial vacuum being applied through the plate, and projects beyond the peripheral edge of the plate. A second sheet of synthetic material covers the lower face of the plate and is attached to the upper covering sheet by the peripheral edges of each sheet to one another beyond the edge of the plate. The packaging provides a tamperproof packaging making display of the packaged product possible.

A packaging film comprises a base film of at least partially water-soluble plastics film, for example, polyvinyl alcohol, carrying on one side a protective layer of particulate inert plastics material, for example, polytetrafluoroethylene powder, having a high water repellency. The film is thus vulnerable to attack by aqueous media on one side and protected against such attack on the other. It may be used, with the protected side innermost, for unit packaging of detergent compositions, especially liquids containing bleach. In use in the washing machine, the unprotected surface is attacked by the wash liquor to release the contents; the protective layer prevents attack of the package by the contents during storage.

A landscape blanket to be used as ground cover in which particles such as crushed stone, marble chips and the like are arranged in a substantially single layer and are held together to form a blanket by sheets of transparent plastic material which conform to the shape of the particles and are bonded thereto without the use of adhesive. The plastic sheets are bonded to the particles by forcing them into contact with the particles while the plastic sheets are in a softened condition.

A method of preserving evidence and later returning the same utilizing a package having an optically transparent film incorporating the evidence and a signed itemization thereof to produce a tamper evident package.
