Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
164 words
A method of forming an inhalant disperser comprising: applying a protective layer of impermeable material on a strip of liquid absorbent paper to form a composite multi-layered strip wherein said protective layer of material is an adhesive applied as a solid coating along the central portions of said strip of paper and as apertured bands on the remaining portions of said strip; folding said composite strip lengthwise to form a trough with said protective layer constituting the inner wall of said trough; placing an ampoule containing a vaporizable liquid in said trough; said trough being shaped to engage a major portion of said ampoule; and sealing said folded composite strip along the open edges thereof to form an enclosure for said ampoule, said adhesive on said strip being meltable under elevated temperatures to effect said sealing of said open edges upon the application of heat thereto in a manner wherein said vaporizable liquid may pass readily through at least portions of said apertured bands.
Claim 2
Independent Claim
164 words
A method of forming an inhalant disperser comprising: applying a protective layer of impermeable material on a strip of liquid absorbent paper to form a composite multi-layered strip wherein said protective layer of material is an adhesive applied as a solid coating along the central portions of said strip of paper and as apertured bands on the remaining portions of said strip; folding said composite strip lengthwise to form a trough with said protective layer constituting the inner wall of said trough; placing an ampoule containing a vaporizable liquid in said trough; said trough being shaped to engage a major portion of said ampoule; and sealing said folded composite strip along the open edges thereof to form an enclosure for said ampoule, said adhesive on said strip being meltable under elevated temperatures to effect said sealing of said open edges upon the application of heat thereto in a manner wherein said vaporizable liquid may pass readily through at least portions of said apertured bands.
Claim 3
Independent Claim
150 words
A method of forming an inhalant disperser comprising: applying a protective layer of impermeable material on a strip of liquid absorbent paper to form a composite multilayered strip wherein said protective layer of material is provided with a multiplicity of closely spaced apertures over the entire surface thereof; folding said composite strip lengthwise to form a trough with said protective layer constituting the inner wall of said trough; placing an ampoule containing a vaporizable liquid in said trough; said trough being shaped to engage a major portion of said ampoule; and sealing said folded composite strip along the open edges thereof to form an enclosure for said ampoule, said protective layer on said strip being meltable under elevated temperatures to effect said sealing of said open edges upon the application of heat thereto in a manner wherein said vaporizable liquid may pass readily through at least portions of said apertures.
Claim 4
Independent Claim
150 words
A method of forming an inhalant disperser comprising: applying a protective layer of impermeable material on a strip of liquid absorbent paper to form a composite multilayered strip wherein said protective layer of material is provided with a multiplicity of closely spaced apertures over the entire surface thereof; folding said composite strip lengthwise to form a trough with said protective layer constituting the inner wall of said trough; placing an ampoule containing a vaporizable liquid in said trough; said trough being shaped to engage a major portion of said ampoule; and sealing said folded composite strip along the open edges thereof to form an enclosure for said ampoule, said protective layer on said strip being meltable under elevated temperatures to effect said sealing of said open edges upon the application of heat thereto in a manner wherein said vaporizable liquid may pass readily through at least portions of said apertures.
Claim 5
Dependent Claim
39 words
A method according to claim 2 wherein said protective layer of material is a film of thermoplastic material laminated on said strip of paper; said thermoplastic material being fusible along said open edges upon the application of heat thereto.
