DEFINITION

Classification: 53/170

(under the class definition) Apparatus including means to encircle or encase the contents of a single package in two or more separate and distinct covers, one cover being superimposed over the other.

(1) Note. The covers may be associated with the contents either as a multi-layered unit or as layers applied in succession.

(2) Note. The application of a closure and a super-imposed hood or cap at a single station in substantially a single infeed operation is not considered to be plural layer cover application for this subclass. See the search notes below.

(3) Note. The application of a cork, cap or crown closure and a sealing spot, disc or gasket (i.e.; contents contacting, protective element) - substantially, simultaneously with the assembling operation - is not considered to be plural layer cover application for this subclass. See the search note below for the locus of this art.

(4) Note. The insertion of a disc into a hood or cap so as to depress said disc and a portion of the hood or cap within the aperture of a receptacle is not considered to be plural cover layer application for this subclass. See the search note below for the locus of this art.
