Abstract
Abstract Packaging apparatus for garments such as pantyhose includes a cylindrical conduit having an entry end and an exit end and spaced apart Venturi air chests on the conduit for establishing a stream of air in the conduit to draw the garment into the conduit at the entry end and accelerate the garment through the conduit and eject the garment into a container at the exit end. A nozzle at the exit end of the conduit has a plurality of apertures or orifices extending through the wall to permit air to exit therefrom to allow the garment to be ejected into the container and maintained therein without being discharged therefrom by the stream of air.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
193 words
Pneumatic packaging apparatus for loading an article to be packaged into an associated container open only at one end, said apparatus comprising a conduit accommodating passage of the article therethrough and having an entry end and an exit end, first means coupled to said conduit for establishing therein a stream of air flowing from said entry end to said exit end to create an area of reduced pressure at said entry end, second means coupled to said conduit and spaced from said first means for adding to said stream of air established by said first means and to enhance the reduced pressure at said entry end, said area of reduced pressure and said stream of air serving to draw the article into said conduit at said entry end and to eject the article from said conduit at said exit end, and mechanism at said exit end for cooperation with the associated container to permit air to escape from said mechanism thereby preventing introduction of the entire stream of air into the container, whereby the article is moved swiftly and continuously through said conduit and into the container and maintained therein after introduction thereinto.

Claim 6
Dependent Claim
19 words
The pneumatic packaging apparatus set forth in claim 1, wherein said conduit is substantially circular in transverse cross section.
Claim 7
Dependent Claim
31 words
The pneumatic packaging apparatus set forth in claim 1, wherein said mechanism at said exit end has a transverse cross section complementary to the transverse cross section of the associated container.
Claim 8
Dependent Claim
211 words
Pneumatic packaging apparatus for loading an article to be packaged into an associated container open only at one end, said apparatus comprising a conduit accommodating passage of the article therethrough and having an entry end and an exit end, first coupled to said conduit for establishing therein a stream of air flowing from said entry end to said exit end to create an area of reduced pressure at said entry end, second means coupled to said conduit and spaced from said first means for adding to said stream of air established by said first means and to enhance the reduced pressure at said entry end, control mechanism for actuating said first and said second means to establish the stream of air into said conduit, said area of reduced pressure and said stream of air serving to draw the article into said conduit at said entry end and to eject the article from said conduit at said exit end, and mechanism at said exit end for cooperation with the associated container to permit air to escape from said mechanism tHereby preventing introduction of the entire stream of air into the container, whereby the article is moved swiftly and continuously through said conduit and into the container and maintained therein after introduction thereinto.
Claim 9
Dependent Claim
211 words
Pneumatic packaging apparatus for loading an article to be packaged into an associated container open only at one end, said apparatus comprising a conduit accommodating passage of the article therethrough and having an entry end and an exit end, first coupled to said conduit for establishing therein a stream of air flowing from said entry end to said exit end to create an area of reduced pressure at said entry end, second means coupled to said conduit and spaced from said first means for adding to said stream of air established by said first means and to enhance the reduced pressure at said entry end, control mechanism for actuating said first and said second means to establish the stream of air into said conduit, said area of reduced pressure and said stream of air serving to draw the article into said conduit at said entry end and to eject the article from said conduit at said exit end, and mechanism at said exit end for cooperation with the associated container to permit air to escape from said mechanism tHereby preventing introduction of the entire stream of air into the container, whereby the article is moved swiftly and continuously through said conduit and into the container and maintained therein after introduction thereinto.
