Abstract
Abstract The present disclosure is directed to a plurality of individual protective safety razor head unit open top casings and a tray for storing the plurality of casings in side-by-side relationships. Each of the casings are adapted to retain a single safety razor cartridge unit therein, each of which have at least one blade and a head cartridge member to which the blade is permanently secured and which also provides a guard surface. The head unit is detachably engageable with a safety razor handle. Each casing defines a single chamber in which a single shaving head unit is retained. The structure in each casing retains the head unit therein against accidental removal in such a manner that the cutting edge of the blade is protected against damage and wherein the head unit is engageable by the handle while the head unit is still within the casing. Each head unit when engaged with the handle is withdrawable from its casing by means of rocking the handle. The tray comprises slide means securing structure to secure each individual casing in the tray in a side-by-side relationship, and the tray and slide means are so configured as to permit each of the casings to be slid endwise out of the tray by the handle engaged with the razor head such that with the handle engaged with the head an operator may remove the blade unit from the casing or may alternatively slidably remove the blade unit and casing from the tray.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
258 words
The combination of a plurality of razor shaving blade assembly units, retaining casings therefor and a flexible plastic storage tray for storing a plurality of said casings in side by side relationship thereon, each of said casings being adapted to retain a unitary shaving blade assembly unit, each shaving blade assembly unit comprising at least one blade and forming a head unit to which the blade is permanently secured and which provides a guard surface, said head unit being detachably engageable with a safety razor handle, each said casing defining a single chamber in which a single head unit may be retained, structure means in each said casing for retaining said head unit, therein against accidental removal in such a manner that a cutting edge of said blade is protected against damage and wherein said head unit is engageable by said handle while said head unit is still within said casing, each said head unit when engaged with said handle being withdrawable from the top of its casing by rocking said handle, said tray comprising slide means securing structure to secure each individual casing in said tray in said side-by-side relationship, and said tray and slide means being so configured as to permit each of said casings to be slid endwise out of said tray transversely thereof by said handle engaged with said razor head unit such that with said handle engaged with said head an operator may remove said blade unit from said casing or may alternatively slidably remove said blade unit and casing from said tray.
Claim 2
Dependent Claim
258 words
The combination of a plurality of razor shaving blade assembly units, retaining casings therefor and a flexible plastic storage tray for storing a plurality of said casings in side by side relationship thereon, each of said casings being adapted to retain a unitary shaving blade assembly unit, each shaving blade assembly unit comprising at least one blade and forming a head unit to which the blade is permanently secured and which provides a guard surface, said head unit being detachably engageable with a safety razor handle, each said casing defining a single chamber in which a single head unit may be retained, structure means in each said casing for retaining said head unit, therein against accidental removal in such a manner that a cutting edge of said blade is protected against damage and wherein said head unit is engageable by said handle while said head unit is still within said casing, each said head unit when engaged with said handle being withdrawable from the top of its casing by rocking said handle, said tray comprising slide means securing structure to secure each individual casing in said tray in said side-by-side relationship, and said tray and slide means being so configured as to permit each of said casings to be slid endwise out of said tray transversely thereof by said handle engaged with said razor head unit such that with said handle engaged with said head an operator may remove said blade unit from said casing or may alternatively slidably remove said blade unit and casing from said tray.
Claim 3
Dependent Claim
130 words
Shaving cartridge retaining casings and a flexible plastic storage tray therefor as claimed in claim 1 wherein each casing is an open top box like resilient plastic casing structure having means within the casing to removably support a cartridge blade assembly in inverted position, plastic walls upstanding from said tray positioned to space a line of said open top plastic casings side-by-side from each other, projecting means extending from said tray walls positioned to engage the tops of said open top box like plastic casings to prohibit withdrawal of the casings upwardly from between said walls but to permit withdrawal of a cartridge from the open top of said casing and permitting the casing and cartridge to be slid transversely of the major axis of the tray for removal therefrom.
Claim 4
Dependent Claim
77 words
Shaving cartridge retaining casings and storage tray therefor as claimed in claim 2 wherein said means within the box like cartridge casing for retaining the cartridge in the casing are vertical alignment posts secured to the casing and resilient clip means at their free ends to restrain the cartridge within the casing to permit withdrawal of the cartridge by rocking it upwardly of the casing through its open top without disturbing the casing relative to the tray.
Claim 5
Dependent Claim
31 words
Shaving cartridge retaining casings and storage tray therefor as claimed in claim 1 wherein the open top box like casings have drain and ventilation openings between their side and bottom walls.
Claim 6
Dependent Claim
102 words
Shaving cartridge retaining casings and storage tray therefor as claimed in claim 1 wherein said slide means between said tray and the open top box like casings are dimpled recesses at the bottom of the ends of said casings along their major axis for resiliently registering with protrusions upstanding from the tray to cause a snap fit between the tray and casing to restrain the casing against sliding endwise of the tray unless subjected to a force sufficient to overcome the engagement of the protrusion upstanding from the tray with the dimpled recess at the underside ends of the open top casings.
