Abstract
Abstract A pressurized or ''''aerosol'''' can containing a composition of matter for producing a string of plastic foam is described. The plastic foam produced from the aerosol can is in the form of a cohesive plastic body sufficiently tacky to adhere to inert surfaces such as walls, windows or the like to support the weight of the foam, however, of insufficient tackiness to adhere with a force greater than the cohesive strength of the foam so that the foamed body can be readily removed from surfaces to which it lightly adheres. Such a combination has substantial play and decorative utility.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
51 words
A toy or decorative combination as defined in claim 1 further comprising: up to about 0.7 percent by weight of a substantially nonvolatile silicone liquid soluble in the composition; and up to about 25 percent by weight of a solvent for the alkyl methacrylate resin that is miscible with the propellant.
Claim 2
Dependent Claim
21 words
A toy or decorative combination as defined in claim 2 further comprising more than about 4 percent by weight of hexabromobenzene.
Claim 3
Dependent Claim
82 words
A composition consisting essentially of: from 10 to 16 percent by weight of a resin selected from the group consisting of polyisobutyl methacrylate, copolymers of n-butyl methacrylate and isobutyl methacrylate, polyisopropyl methacrylate, polyisopentyl methacrylate, polyisohexyl methacrylate, polyisoheptyl methacrylate, and polyiso-octyl methacrylate; from 0.5 to 4.0 percent by weight of sorbitan trioleate; from 0.1 to 5.0 percent by weight of plasticizer for the resin; and fluorinated hydrocarbon propellant for ejecting the composition from a pressurized container as the principal balance of the composition.
Claim 4
Dependent Claim
27 words
A composition as defined in claim 4 wherein the fluorinated hydrocarbon comprises up to about 25 percent by weight of trichloromonofluoromethane; and the balance is principally dichlorodifluoromethane.
Claim 5
Dependent Claim
22 words
A composition as defined in claim 5 wherein the plasticizer is selected from the group consisting of dibutyl phthalate and dimethyl chlorendate.
Claim 6
Dependent Claim
103 words
A composition consisting essentially of: from 10 to 16 percent by weight of a resin selected from the group consisting of polyisobutyl methacrylate, and copolymers of isobutyl methacrylate and n-butyl methacrylate; from 0.5 to 4.0 percent by weight of sorbitan trioleate; from 0.5 to 5.0 percent by weight of plasticizer for the resin, selected from the group consisting of dibutyl phthalate and dimethyl chlorendate; And fluorinated hydrocarbon propellant for ejecting the composition from a pressurized container as the principal balance of the composition, wherein the fluorinated hydrocarbon comprises up to about 25 percent by weight of trichloromonofluoromethane; and the balance is principally dichlorodifluoromethane.
Claim 7
Dependent Claim
18 words
A composition as defined in claim 4 further comprising more than about 4 percent by weight of hexabromobenzene.
Claim 8
Dependent Claim
48 words
A toy or decorative combination as defined in claim 1, wherein the plasticizer is present in the proportion of about 0.1 to 5.0 percent by weight of the composition; and the propellant comprises up to about 25 percent by weight of trichloromonofluoromethane and a balance of principally dichlorodifluoromethane.
Claim 9
Dependent Claim
167 words
A toy or decorative article comprising: a pressure resistant container; valve means for controlling flow from the container; a composition in the container comprising: from about 10 to 16 percent by weight of methacrylate resin for forming a cohesive body of plastic foam after ejection from the container, selected from the group consisting of polyisobutyl methacrylate, and copolymers of n-butyl methacrylate and isobutyl methacrylate, from about 0.1 to 5.0 percent by weight of plasticizer means for assuring plasticity of the body of foam, selected from the group consisting of dibutyl phthalate, dimethyl chloroendate; from about 0.5 to 4.0 percent by weight of sorbitan trioleate for controlling tackiness of the body of foam, and propellant means comprising up to about 25 percent by weight of trichloromonofluoromethane and a balance of principally dichlorodifluoromethane for ejecting the composition from the container, said resin, plasticizer, and sorbitan trioleate being substantially soluble in the propellant; and nozzle means for ejecting the composition from the container as an elongated string of plastic foam.
Claim 10
Dependent Claim
24 words
An article as defined in claim 10 further comprising up to about 0.7 percent by weight of substantially nonvolatile silicone liquid in the composition.
Claim 11
Dependent Claim
18 words
An article as defined in claim 10 further comprising more than about 4 percent by weight of hexabromobenzene.
Claim 12
Dependent Claim
136 words
A toy or decorative article comprising: a pressure resistant container; valve means for controlling ejection of material from the container; nozzle means for ejecting material from the container as an elongated body; and a composition in the container for forming an elongated string of plastic foam sufficiently tacky to support the weight of said body and less than sufficiently tacky to have an adhesion to an inert surface greater than the cohesion of the body of foam, said composition consisting essentially of; about 12.2 percent by weight of polyisobutyl methacrylate; about 2.5 percent by weight of sorbitan trioleate; about 0.44 percent by weight of dibutyl phthalate; about 0.35 percent by weight of silicone liquid; a sufficient quantity of pigment to enhance a decorative effect; about 6.60 percent by weight of trichloromonofluoromethane; and a balance of dichlorodifluoromethane.
