Abstract
Abstract A flexible, T-shaped clip having retention shoulders projecting from the opposite ends of its elongated crossmember as well as from the free end of its central web section is utilized to hold a plurality of stacked fiberboard containers together by inserting the retention shoulders of the crossmember in aligned apertures of adjoining, vertical sidewalls of two containers and engaging the opposed shoulders on the horizontally extending web section in the abutting top and bottom walls of the two containers through apertures therein. Raised beads on the retention shoulders assist in holding them in locking engagement with the apertured walls of the containers.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
89 words
A fastening device for securing a plurality of file cases together in a multiple compartment assembly comprising: an elongated crossmember with inwardly extending lock shoulders on the opposite ends thereof; and a central web section of flat, planar configuration projecting from said elongated crossmember substantially perpendicular thereto, and defining therewith a T-shaped clip, said web section having lock shoulders projecting from the opposite sides thereof, said lock shoulders on said crossmember and on said web section being adapted to firmly engage the walls of abutting cases through apertures therein.
Claim 2
Dependent Claim
89 words
A fastening device for securing a plurality of file cases together in a multiple compartment assembly comprising: an elongated crossmember with inwardly extending lock shoulders on the opposite ends thereof; and a central web section of flat, planar configuration projecting from said elongated crossmember substantially perpendicular thereto, and defining therewith a T-shaped clip, said web section having lock shoulders projecting from the opposite sides thereof, said lock shoulders on said crossmember and on said web section being adapted to firmly engage the walls of abutting cases through apertures therein.
Claim 3
Dependent Claim
20 words
A fastening device as defined in claim 1 wherein: said clip is manufactured as an integral unit from vinyl resin.
Claim 4
Dependent Claim
95 words
A fastening device as defined in claim 1 wherein: each of said lock shoulders on the opposite ends of said crossmember comprises an inwardly extending portion projecting at an angle from said crossmember and a lip depending from the inner edge of each of said inwardly extending portions on the side thereof facing said web section, whereby said lock shoulders may extend inwardly over the walls of said cases through said apertures therein and be held in firm engagement therewith by the gripping of said shoulder lips against the inside surface of said casing walls.
Claim 5
Dependent Claim
112 words
In an assembly of file cases positioned adjacent each other, a plurality of improved fastening devices holding said cases together to provide a multiple compartment unit wherein each of said fastening devices comprises: a T-shaped clip having a crossmember overlying aligned, coplanar walls of two of said cases, and a web section lying between two abutting walls of said cases extending at right angles and adjacent to said coplanar walls, said web section comprising a single, planar member; and lock portions on the opposite ends of said crossmember and on the opposite sides of said web section, said lock portions being secured in engagement with said casing walls through apertures formed therein.
Claim 6
Dependent Claim
112 words
In an assembly of file cases positioned adjacent each other, a plurality of improved fastening devices holding said cases together to provide a multiple compartment unit wherein each of said fastening devices comprises: a T-shaped clip having a crossmember overlying aligned, coplanar walls of two of said cases, and a web section lying between two abutting walls of said cases extending at right angles and adjacent to said coplanar walls, said web section comprising a single, planar member; and lock portions on the opposite ends of said crossmember and on the opposite sides of said web section, said lock portions being secured in engagement with said casing walls through apertures formed therein.
Claim 7
Dependent Claim
66 words
The structure of claim 4 wherein: said casings are slit to form hinged flaps in said walls which may be displaced to provide said apertures; and said clips include outwardly angling elements on said ends of said crossmember and on the opposite sides of said web, said elements serving to push said flaps inwardly to thereby open said apertures within which said lock portions are engaged.
Claim 8
Dependent Claim
112 words
A clip for securing a plurality of file cases together to form a multiple compartment assembly comprising: an elongated, flexible member having retention shoulders extending angularly from the opposite ends thereof, said shoulders being adapted to engage apertures in adjoining, coplanar walls of two file cases positioned in abutting engagement with each oTher; an inwardly turned lip on each of said shoulders; said lips being adapted to hold said shoulders in locking engagement with said apertured walls; and outwardly sloping tabs on the opposite ends of said flexible member depending from said retention shoulders, said tabs being adapted to inwardly displace hinged flaps covering said apertures in said walls of said cases.
Claim 9
Dependent Claim
112 words
A clip for securing a plurality of file cases together to form a multiple compartment assembly comprising: an elongated, flexible member having retention shoulders extending angularly from the opposite ends thereof, said shoulders being adapted to engage apertures in adjoining, coplanar walls of two file cases positioned in abutting engagement with each oTher; an inwardly turned lip on each of said shoulders; said lips being adapted to hold said shoulders in locking engagement with said apertured walls; and outwardly sloping tabs on the opposite ends of said flexible member depending from said retention shoulders, said tabs being adapted to inwardly displace hinged flaps covering said apertures in said walls of said cases.
Claim 10
Dependent Claim
44 words
A clip as defined in claim 6, wherein said flexible member is bowed outwardly away from said shoulders to thereby impart an inwardly directed spring action to said outer ends thereof to assist in maintaining said shoulders in gripping contact with said casing walls.
