RECLOSABLE DISPENSING CARTON Filed April 7, 1958 INVENTOR. #4 14M 14. fi VG'LE W zw RTT'OQNEYS.

United States Patent RECLOSABLE DISPENSING CARTON William A." Ringler, 'Wayne, "-Pa.,- assignorto Diamond Gardner -Corporation,"= Middletowm' Ohio, a- I corporation'of Ohio Application April 7, 1958, Serial No; 726,866

16 'Glaimse (C12229- 17) This invention relates to paper cartons-and more par- 1- tioularly to a reclosable-dispensing carton having an" integral liftable part which, when raised;--provides-- a dis- "pensing' opening for the contents 'of the carton.

A; principal object 'of the inventiorr-isthe provision of aone-piece carton structure' having a tubular -body-and seabend flaps which may be erectedandsecured in conventional-fashion, the'structure incorporating-as apart thereof a'hinged cover-member"which,=when separated from the remainder of the carton, provides a reclosable dispensingopening.

*Aiurtherobject of the invention is theprovision of 'an integral friction -lock' by means-"of which the liftable *cover majr he -maintained in closed position subsequent "toits initial-'separationfrorn the carton.

Still a further object of 'theinvention is'theprovision of areclosable dispensing car-tonin-which al-iftable cover r member is 'formed in part from the top closure of'thercaritoir and in-part from-three contiguous body walls," the body wan parts being- --separ able'-from the remainder of thebody walls along lines for -severance,athe structure including aninner liner forming part which lines the carton Figure 7 is a verticaltsectionalwiew similar to Eigure. 6 but illustrating ,-the manner in.,-which:=the;-parts separate when'th'e cover istraised.

Referring first toFigure, 1lof-"thendrawingsn'Lhave therein illustrated a one-piecetpaperboard.blank:cutuand scored to provide .bodywall-s 1,: 2,2 3:;and" 4 -in'.a1ticulation in the order. named, the. wall. 41 having a glue fiapi 5 con- --trated,'the1 flaps 7 and. 8,:are of fullwidth. so :as to overlap throughout substantially.- theirrentire extent in the erected structure zalthough, itwill be; ;understood thattheewidth -of the flaps may be. reduced to provide. anfeconomyt seal in which 1 only their outer portions overlap to providea glue seam extending tcentrallyaof-the top iclosure. "F'Lhe body wall 3 is provided at its. uperendtwith a:pair.*of.fiap parts. 9 and 10, theflapzpart' 9..being .hingedlyoonnected to' the upper edgetof: the .body wall 3 with the, fiap. part.-:10 20.

' In the erection and -assembly of the structure, -the -rirn --forming extension 13-will be first-t-infolded to thmposition ill-ustrated in dotted line -inFigure 1, a ;striperof ad *hesive' '22- being first applied:.to :theouter edge ofi ltthe -extension,--whereupon it is infolded-walong- :ihe eline for -servance 11, thereby juxtaposing a the- .central portion 14- to body wall 3, with -wing'portions 15 :and .161 juxtaposed to body walls 2 and 4;-respectively.""Thewdimensiom'ng-of-the parts is such that the: glue stripe 22 will lie beyond the -lines-for severance"17; 18 and 19,- aswill -be apparent from the drawings, and the-width of :the: flaps 9 and '10 is such that theedges"23ofi wing portions 15 and 16 will be spaced inwardly' with respect-to -thel lines of articulation connecting theend'closurfiaps 7 and 8 to their respective body walls": The amount ofispacing in- =volved is simply-enough-to clear thelines of articulation -between-the body walls'and-end'closure fiaps-so' thatvthe end closure fiaps may. be freely'infolded: without inter- @ference from the extension It will be noted also" that-the length of the extension is such: that the outerends ofwthe ---wing portions 15-and"16=:extend beyond theoutermost -ends'of the lines for severance17 and- 19; and similarly,

. the width of theextension is such'.thatnthezpartsoextend for severance.

j; Subsequent toj:the, infolding; ,andadhesive attaqhrnent carton blank will be tubed in conventional manner, with flap 5, whereupon the tubular body will be erected and the end closure flaps infolded and secured together.

As seen in Figure 2, the formation of the top end closure is efiected by infolding the juxtaposed flaps 9 and with the application of adhesive to the upper surface of flap 9, such adhesive being indicated at 24, whereupon the end closure flaps 7 and 8 are infolded with the interposition of adhesive therebetween. 7 which contains the score line 21 will lie outermost so that the liftable cover member will be hinged to the outermost part making up the end closure. While the liftable part also folds along the line 21, I prefer to cutscore or perforate the line 21 to facilitate the folding of the cover part. It will be understood, of course, that the lines 20 and 21 coincide in the assembled structure. Upon being folded and glued, the top closure assumes the condition illustrated in Figure 3. The contents will Preferably the flap have, of course, been placed within the container prior to the sealing of one of the end closures.

, In the hands of the user, the liftable cover part, which is designated by the reference numeral 25, will be separated from the remainder of the carton along the lines for severance 17, 18 and 19, thereby permitting the cover part to swing upwardly in the manner illustrated, in Figure 4. At such time as the cover part is initially opened, the act of swinging the part upwardly will cause the flaps 9 and 10 to separate along the line for severance 11. As will be apparent from Figure 4, the flap 9 is secured to the inner surface of the liftable cover part whereas the flap 10 will remain articulated to the upper edge of the central portion 14 of rim forming extension 13. Thereafter, as seen in Figure 5 the flap 10 will be folded outwardly in the manner illustrated. In this position it serves both as a pouring lip for the contents and, when the cover part is reclosed to fit over the exposed areas of the rim forming extension, the reversely folded flap serves a friction lock acting to maintain the cover part in tightly closed condition. In this connection, and as best seen in Figure 7, the width of flap 10 will be substantially equal to or slightly less than the width of the front wall 311 of the cover part.

The arrangement just described provides an eco-- nomical and easy to make one-piece reclosable carton. At the same time, the construction provides an integral friction lock which will maintain the reclosable cover in the closed position. Without such lock the natural resiliency of the board tends to partially open the cover,

thereby exposing the contents and permitting it to readily spill from the carton should the carton be tipped over.

Modifications may be made in my invention without departing from the spirit of it and, consequently, I do not intend to be limited excepting in the manner set forth .in the claims which follow.

.formed from contiguous portions of three body walls of said carton, said depending wall portions being defined by lines for severance by means of which said cover part may be separated from the remainder of said body walls and folded upwardly along the line of hinged connection to said end closure, a rim forming extension secured to the inner surfaces of said three body walls immediately below the lines for severance therein, with portions of said extension projecting upwardly beyond the said lines for severance and juxtaposed to the inner surfaces of the depending wall portions of said cover part when said cover part is in the closed position, a first flap member articulated to the upper edge of said extension, and a second flap member connected to said first flap member alon a line for. severance, said second flap member being secured to said liftable cover part, said two flap members being separable along their said line for severance when said cover part is initially opened, said first flap member, upon being separated, defining a cover securing flap which, when reversely folded to overlie the outer surface of said extension, provides a friction locking element for securing said cover part in closed position.
