Claim 6

The package of claim 4 wherein said lugs are provided for contacting each said blade unit frame adjacent its four corners beyond the ends of the shaving edges.

Claim 7

The package of claim 5 wherein each said recess has sloping walls providing cam surfaces to permit blade unit withdrawal from said package by a lug-flexing movement of said unit away from said floor, and each said lug has a sloping cam surface at its free end to permit blade unit installation in said package by a lug-flexing movement of said unit toward said floor.

Claim 8

The package of claim 1 wherein each said tab has a bottom surface which tapers toward a concave finger-receiving front edge.

Claim 9

A dispenser package for a plurality of razor blade units each comprising a blade-carrying frame, said package comprising a floor, side walls transverse to said floor, and resilient lugs upstanding from said floor and arranged in groups to contact each said blade unit adjacent its four corners beyond the ends of the shaving edges, each said lug having upper and lower projections spaced above said floor and defining between them a recess for receiving a side portion of a said blade unit, each said projection having a sloping wall facing the said recess adjacent thereto to provide cam surfaces permitting blade unit withdrawal from said package by a lug-flexing movement of said unit away from said floor, each said upper projection having a sloping surface facing away from said recess adjacent thereto to provide a cam surface at the free end of said lug permitting blade unit installation in said package by a lug-flexing movement of said unit towards said floor.

Claim 10

A dispenser package for a plurality of razor blade units each comprising a blade-carrying frame, said package comprising a floor, side walls transverse to said floor, and resilient lugs upstanding from said floor and arranged in groups to contact each said blade unit adjacent its four corners beyond the ends of the shaving edges, each said lug having upper and lower projections spaced above said floor and defining between them a recess for receiving a side portion of a said blade unit, each said projection having a sloping wall facing the said recess adjacent thereto to provide cam surfaces permitting blade unit withdrawal from said package by a lug-flexing movement of said unit away from said floor, each said upper projection having a sloping surface facing away from said recess adjacent thereto to provide a cam surface at the free end of said lug permitting blade unit installation in said package by a lug-flexing movement of said unit towards said floor.

Claim 11

The package of claim 8 wherein some of said lugs have on opposite sides thereof a pair of said recesses for respectively retaining two said blade units in said package.

Claim 12

A dispenser package for a plurality of razor blade units, each blade unit comprising a frame carrying means defining opposed shaving edges, said package comprising a floor, a perimeter wall upstanding from said floor, and a plurality of flexible resilient latch posts upstanding from said floor and arranged in groups to secure blade units in said package, each said group of posts being arranged to engage a blade unit beyond the ends of said shaving edges, each said post having upper and lower projections spaced above said floor and defining between them a recess for receiving a side portion of a said blade unit, each said projection having a sloping wall facing the said recess adjacent thereto to provide cAm surfaces permitting blade unit withdrawal from said package by a post-flexing movement of said unit away from said floor, each said upper projection having a sloping surface facing away from said recess adjacent thereto to provide a cam surface at the free end of said post permitting blade unit installation in said package by a post-flexing movement of said unit towards said floor.

Claim 13

A dispenser package for a plurality of razor blade units, each blade unit comprising a frame carrying means defining opposed shaving edges, said package comprising a floor, a perimeter wall upstanding from said floor, and a plurality of flexible resilient latch posts upstanding from said floor and arranged in groups to secure blade units in said package, each said group of posts being arranged to engage a blade unit beyond the ends of said shaving edges, each said post having upper and lower projections spaced above said floor and defining between them a recess for receiving a side portion of a said blade unit, each said projection having a sloping wall facing the said recess adjacent thereto to provide cAm surfaces permitting blade unit withdrawal from said package by a post-flexing movement of said unit away from said floor, each said upper projection having a sloping surface facing away from said recess adjacent thereto to provide a cam surface at the free end of said post permitting blade unit installation in said package by a post-flexing movement of said unit towards said floor.

Claim 14

The package of claim 10 wherein a plurality of said posts each define a pair of recesses, each said pair of recesses being on opposite sides of said post for respectively engaging surfaces of two blade units in said package.

Claim 15

The package of claim 11 wherein said posts are arranged in opposed pairs and define opposing recesses for receiving and retaining opposite sides of said blade units.

Claim 16

The package of claim 12 wherein said posts are arranged in groups of four for contacting each said blade unit frame adjacent its four corners beyond the ends of the shaving edges.

Claim 17

The package of claim 14 wherein a first member defines said floor and a first component of a mechanical interlock, and a second member defines said perimeter wall, a plurality of breakway tabs extending from said perimeter wall, and a second component of said mechanical interlock, said interlock components being adapted to cooperate when said first and second members are brought together to retain said first and second members together with said tabs spaced above said floor by at least the thickness of a blade unit.

Claim 18

The package of claim 14 wherein said first mechanical interlock component comprises a chamfered projection extending laterally beyond an edge of said first member, and said second mechanical interlock component comprises a recess in said perimeter wall for receiving said projection.

Claim 19
