(Cl. 24-16) This invention relates to box fasteners, and more particularly to an improved fastening buckle assembly for use on the hinged cover segments of a corrugated cardboard carton.

A main object of the invention is to provide a novel and improved fastening buckle assembly for a corrugated cardboard carton, the assembly being relatively simple in construction, being easy to install, and providing an etiicient means for holding the hinged cover sevments of a carton in closed positions.

A further object of the invention is to provide an improved fastening buckle assembly for detachably securing together the hinged cover segments of a corrugated cardboard carton, the assembly involving relatively inexpensive components, providing a reliable connection between the hinged cover segments to maintain them closed, and enabling various types of corrugated cardboard cartons to be efficiently employed as storage containers without requiring any substantial modification of the cartons.

Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings, wherein:

te States Patent 0 Patented dan. 21, 1964 Referring to the drawings, 15 and 16 respectively designate the hinged cover segments of a conventional cardbeard carton made of corrugated cardboard or paper material. Designated generally at 17 is a fastening tongue ember adapted to be secured to the marginal portion of one of the segments, for example, the cover segment 15, and designated generally at 13 is a sleeve member adapted to be secured to the marginal portion of the opposing cover segment 16 in alignment with the tongue member 17 and being arranged to lockingly cooperate with the tongue member, as will be presently described.

The tongue member 17 comprises an elongated main body of resilient material, for example, of sheet metal, said main body being shown at 19. The body 19 tapers in width and terminates in the rounded free end portion Ztl. At its widest end portion the body 19 is formed with a pair of depending

bendable fingers

21, 21, said lingers being adapted to be engaged through a pair of

parallel slots

22, 22 formed in the cover segment 15 and to be bent laterally outwardly to the positions thereof illustrated in FEGURE 6, wherein it is seen that the

lingers

21, 21 closely underlie the bottom surface of the cover segment 15 and thus lockingly secure the tongue member 17 to said cover segment in a position wherein said tongue member extends substantially perpendicular to the adjacent edge 23 of the cover segment.

The sleeve member 1S comprises a suitable main body of sheet metal or other relatively durable material, shown at 24, said main body being formed with the opposing

marginal guide channels

25, 25 adapted to receive the margins of the tongue member 19 therein, the body 2dbeing further integrally formed with a pair of depending laterally

bendable locking linvers

26, 26 which may be engaged through a pair of

parallel slots

27, 27 formed in the cover segment 16 and which may be bent laterally outwardly to the positions thereof illustrated in FEGURE 2, whereby to securely fasten the sleeve member 18 to the cover segment 15 in the manner illustrated in FIGURE 2. Thus, the

slots

27, 27 are accurately aligned with the

slots

22, 22, so that the tongue member 17, when installed, is accurately aligned with the sleeve member 13, when installed, so that the tongue member will readily engage through the sleeve member and its side edges will be received in the

opposing channels

25, 25.

The body 24 is termed at its respective transverse edges with the upwardly

curved guide lips

27, 27 to facilitate the insertion of the body 1@ of tongue member 17 therebeneath, and the body 24 is further formed with a depending, transverse, generally V-shaped locking corrugation ZS located substantially centrally of said body.

The flexible tongue member 17 is formed with a longitudinally extending series of transverse corrugations 3Q, located at the intermediate portion of the tongue body 19 and being of substantial length. The corrugations 30 are adapted to lockingly cooperate with the transverse locking corrugations 2:8 on the body member 24- of sleeve 13 in the manner illustrated FIGURES 4 and 5. Thus, when the ilexible tongue member 17 is inserted through the sleeve 18, the body 19 is pulled through the sleeve, said body being suiiciently resilient to allow the corrugations 3i) to pass the depending locking corrugations 2S beneath the main body 24 of the sleeve member. Thus, the tongue body 19 may be pulled through the sleeve until it is relatively taut, after which it may be bent back over the sleeve member 18 and may be engaged in a ilat locking loop 31 provided on the tongue member adjacent the

fingers

21, 21, in the manner illustrated in FGURE 5. With the free end portion of the tongue body 19 engaged in the :dat locking loop 31, the fastening buckle assembly is securely held in locked position, and the

cover segments

15 and 16 are held in closed positions.

As will be readily apparent, to unfasten the buckle asn.9 sembly, it is merely necessary to disengage the end portion of the tongue body 1% from the locking sleeve 31, alter which the tongue body may be pulled to the left, as viewed in FIGURE 5, namely, in a direction to di"- engage the tongue member from the sleeve member 18, until finally the tongue member is completely disengaged from the sleeve member, releasing the cover segments and 15.5.

As shown in FGURES 9, 10 and 1l, the sleeve member, shown at 18', may be formed with a plurality of transverse locking corrugations instead of a single corrugation, for example, may be formed with two successive transverse depending

locking corrugations

28, 28 instead of with merely a single transverse locking corrugation, as in the form or the invention illustrated in FTGURES 1 to 8.

FIGURES 12, 13 and 14 illustrate a typical slit-forming tool which may be employed to form the aligned pairs oi

parallel slits

22, 22 and Z7, 27 shownV in PTGURE 8. Thus, the tool, which is designated generally at 40, may comprise a resilient band 41 of spring steel, or similar resilient material, formed at each end with the pairs of parallel depending blades 42, and 4:3, 43, as shown in in FTGURES 13 and 14. Secured to the band 4i inwardly adjacent the

respective blades

42, 42 and 43, 43 are respective ltransversely extending depending stop llanges 44 and 45 adapted to be employed as positioning elements engageable with the edges of the cover segments 1S and 16 to accurately position the slit-forming

blades

42, 42 and 43, 43. Thus, for example, the llange 44 engages against the edge 23 of cover segment 15, and the

blades

42, 42 are pushed through the cover segment, thereby forming the

slots

22, 22 illustrated in FIGURE 8. In a similar manner, the llange 45 is positioned against the edge of the opposing cover segment 16, While the

blades

43, 43 are pushed through the cover segment to form the

slots

27, 27. lt will thus be seen that the

slots

22, 22 and 27, 27 are thus accurately longitudinally aligned with each other because they are formed by the

blades

42, 42 and 43, 43 carried on the respective end portions of the elongated aligning band 41. lt will be further seen that the slots are spaced inwardly from the edges of the cover segments by predetermined, accurately established distances, so that the tongue member 17 and sleeve member 18, when subsequently installed, will be spaced apart by the correct distances to insure proper locking cooperation thereof.
