DEFINITION

Classification: 424/443

Web, sheet or filament bases; compositions of bandages; or dressings with incorporated medicaments:

(under subclass 400) Subject matter in which the special physical form contains a coated, impregnated of two layer web, sheet, a filament or is a coated or impregnated bandage or dressing.

(1) Note. This subclass provides for physical forms wherein the coated or impregnated base or substrate is of a length or width which is proportionately larger than the thickness thereof; e.g., woven textile material, felted self sustaining mat, film, continuous or indeterminate length filament, synthetic resin film, leather, etc. Fibers nominally recited are excluded from this subclass.

(2) Note. A web sheet or filament base coated with a compound or composition merely to preserve the base against biological attack is excluded from this and indented subclasses (see SEARCH CLASS below).

(3) Note. This and indented subclasses provide only for articles having a maximum of two layers and lacking sufficient structure to be placed in other classes based on structure (see SEARCH CLASS below).

SEE OR SEARCH THIS CLASS, SUBCLASS:

414+, for a synthetic resin foil coated or impregnated with a biocide.

419, for a biocidal particle coated with a synthetic resin.

462, for a sustained or differential release capsule containing discrete particles coated with a synthetic resin. 482, for a table coated with a solid synthetic resin.

497, for a synthetic resin coated particle.

501, for a synthetic resin impregnated particle.

47, Plant Husbandry,

23+, for a plant guard containing a biocide and subclass 56 for a seed tape containing a biocide, and subclass 56 for a seed tape containing a biocide, claimed in terms of particular structure or shape, or claimed in combination with

plants or seeds.

57, Textiles: Spinning, Twisting, and Twining, especially

200, and 241 for a yarn, cord or cable which is coated or impregnated with a compound composition to protect the yarn, cord or cable against biological attack.

162, Paper Making and Fiber Liberation,

161, for a process of making paper wherein a biocide is used in the process and the resulting product containing a biocide wherein the biocide protects the product from biological attack.

428, Stock Material or Miscellaneous Articles, appropriate subclasses for a stock material product in the form of a single or plural layer web or sheet of the type therein provided, and for which there is no other provision and which is coated or impregnated with a compound or composition to protect the article against biological attack, see 607, (a cross-reference art collection) for a product which has been treated to be resistant against plant or nasal attack. An article impregnated with a biocide and not containing structure (e.g., size or apertures) and not elsewhere provided (e.g., Class 428, sublcasses 540+) will be classified in Class 424. Class 428 provides for a claim to a coated or impregnated article, not otherwise provided for, which comprises a base preserved by a composition or compound which has a Class 424 utility, (e.g., mothproofed textile or termite proofed wood). Class 424 provides for a claim to a base coated with a compound or composition which has a Class 424 utility and in which the base function as a carrier for the active material (e.g., medicated applicator or mosquito repellent fabric). Class 424 also provides for a claim to a coated dosage unit containing a substance having a Class 424 utility. Class 128, provides for bandages, body-applicators or body dressing which contain a medicine and are claimed in terms of more structure than a randomly distributed single layer on a base material or randomly impregnated base material. For example, Class 128 takes a base material wherein certain portions thereof are impregnated with an adhesive and other portions are impregnated with a Class 424 medicine at those places where there is no adhesive backing on a gauze impregnated with a Class 424 composition, etc. Class 128 also provides for a bandage, body applicator or body dressing containing a Class 424 composition and which is claimed in terms of specific structure; e.g., pore size, thickness, length, width, etc. Class 424 takes bandages, body applicator or body dressing which contains a specific or nominally recited medicinal ingredient which is either randomly distributed in a singly layer on a base material or randomly impregnated in a base material.
