17 Claims. (Cl. 229-17) The present invention relates generally to the packaging field. More specifically, the invention concerns a novel dispensing container and blank of bendable sheet material such as paperboard, finding particular, but not exclusive, utility when fabricated in a form commonly known as a gable top. Such containers are particularly well adapted for the packaging of milk and other comestibles but may, of course, be employed for packaging a wide variety of fluent substances.

My copending U. S. applications, Serial No. 266,572, filed January 15, 1952, and Serial No. 269,785, filed February 4, 1952, and copending U. S. application Serial No. 321,217, filed November 18, 1952, by Francis E. Makuta, disclose dispensing containers having improved pouring characteristics and blanks for making such containers.

Each of these containers has a pouring lip adjacent the pouring opening so as to prevent dribble during pouring and cut-off, irrespective of the fluid level in the container or the size 01' rate of flow of the poured stream.

The general aim of the present invention is to provide, in a container and blank having a dispensing means including a pouring lip, a pouring mechanism representing an improvement over the constructions disclosed in the foregoing applications.

A more specific object of the present invention is to provide a container and blank of the character set forth arid which will include a novel arrangement for manipulating a pouring lip such as the one disclosed in Makuta application Serial No. 321,217, referred to above Another object is to provide a container and blank of the character set forth including structural features capable of implementing the objectives just recited but susceptible of economical manufacture at a cost comparing favorably with that required for paperboard containers presently available to the trade.

Other objects and advantages will become apparent from the following detailed description, taken together with the accompanying drawings in which:

Figs. 13 to 19, inclusive, are views similar to Figs. 6 to 12, respectively, but showing a further modified form of container and blank also embodying the invention.

While the invention is susceptible of various modifications and alternative constructions, certain illustrative embodiments have been shown in the drawings and will be described below in considerable detail. It should be understood, however, that there isno intention to limit the invention to the specific forms disclosed, but, on the contrary, the intention is to cover all modifications, alternative constructions and equivalents falling Within the spirit and scope of the invention as expressed in the appended claims.

Referring more specifically to Figs. 1 to 5, inclusive, the invention is there exemplified in an illustrative container 20 and a container blank 20A from which the container 20 may be formed. The container 20, which will be recognizedas a gable top container by those skilled in the art, and the blank 20A, may be manufactured from paperboard or other bendable sheet material. When erected, the container 20 is self-sustaining in shape and may be coated or impregnated with parafiin or some other appropriate substance to make it moistureproof and capable of holding fluids such as milk. In this instance, the container 20 comprises a tubularbody 21 of approximately square or rectangular cross section and havinga top end closure 22 surmounted by a central laminar rib 24. The container body 21 also has a bottom end closure (not shown) of any suitable form, the details of the bottom closure constituting no part of the present invention. Flanking the laminar rib 24, the top end closure 22 has a pair of inclined roof panels 25, 26. The latter respectively adjoin front and rear body panels 28, 29 along a common score line 30 which separates the top closure 22 from the container body 21.

The contents of the container 20 may be dispensed through a suitable pouring opening in one of the roof panels 25, 26. In this instance, the roof panel 25 is provided with a sanitarily protected pouring opening 31 initially covered by a lift tab 32 (Figs. 1 and 2). The pouring opening 31 is cut into a pouring opening ply 34 of sheet stock bonded to the inside face of the roof panel 25 and the body panel 28. The pouring opening 31 and the sanitarily protected margins thereof are initially covered by the lift tab 32, becoming exposed upon elevation of the latter by the user. The lift tab 32 in this case is integral with the roof panel 25 and the body panel 28, being defined therein by means of a pair of spaced apart severance lines 35, 36 which terminate at their lower ends in a finger recess 38. A reclosure plug 39, defined in the pouring opening ply 34 by the incisions 40, 41, 42 which also define the pouring opening 31, is bonded to the inner face of the lift tab 32. Thus the reclosure plug 39 for all intents and purposes actually behaves as an integral part of the lift tab 32 and is movable with it. After initial opening of the container, if the lift tab 32 be moved to its closed position, the plug 39 simply snaps into its original position in the pour- 2,73 also ing opening 31 and the frictional effect between the perimeter of'the plug 39'and the opening 31 serves yieldably to maintain the lift tabf32 in closed position.

In order to. give the. container... 20...- dribble=free pouring and.cut otfflcharacteristics the container 20. is. formed:

erative: position wherein its.- frieei edge overhangs. the. fingerrecess. 38 and the ifaeeof. the underlying body; panel.

269,785, as well as in-Maltuta:appIicationSerial: No; 321,217, supra.

Provision; is made in the construction of. the blank 29A and the container 20 so that the pouringlipzetiwill be displaced automatically as: an: incidentto raisingthe lift tab 32. during; initialz opening; of the: container; is. accomplished: by the use: of. a. severable'. connection between the liftstab 32tand the pouring'lipti44, such connection' beingsituated" at a: point spaced v from the respective hinge linesof both the. lip:- 442 and the: tab. 32.

In the present instance, the foregoing is accomplished.

by means of at least one. severable-tie-46 of paperboard stock which is: left inthe pouringzopening plyM' between the free: edge 45 ofzthepouri'ng lip and thercorrr plementary adjacent edge of the reclosure plug 39.- As indicated in: Figs. 1, 2, 4- and. 5,.th'e.tie 461 is. situated near the midpointoftthe incision line 41 and. interrupts:

aresulting;upwardtzangularunovement ofithe' pouring lip 44 about its..hinge"linea43,-z the stressin the tie 46 in creasingsharplyas elevation of the-:lifit tab 32 progresses.

Eventually, thetie 46 seversfiunder'stress, permit-- ting the lift tab' 32. to be. fullyelevatedby the user 'and leaving-the pouring lip? 44min an-upstandingcondition.

out of thezplane. ofc'thez'pouring'zopening" ply 3'4; as" in dicated in Fig. 2. While the angulhridistancethrough whiclnthe pouring lip .44 has moved may be insufiicient to effect full reaiizationof'thergoodt pouring' qualities'ot' which the. containerlil isicapable; such m'ovement-will' be sufiicient to remindLtheuser' that good pouri-ngmay.

bernore fully achieved by urgingthe-pouring lip144-to its fully downfoldedzposition aboutits hinge li-ne 43, such. position. being-showrtin Fig; 3.

Reclosure of the: pouring opening may be effected regardless of'whether thepouring lip 44 is'in'its fully down-- folded position or has: been returned manually to approximately its original dormant position because in either event the .reelosure: plug 39 -will .frictionally engage a. substantial: portion: of the perimeter of thepouring opening 31;.

Turningnow to Figs. 4 and'S; certain detail'sof the'blank A. arev thereshownt In this instance, it willbenoted that the pouringopening ply 34-constitutes-a separate patch 48- having a-transverse score line 49. The patch48also has defined therein the reclosure plug 39 and the pouring; lip 44ers well as' the connecting tie 46.. The main portion. of the blankZilA, on the other hand, has. thelift tab 32 and the finger recess 38 already, defined therein. After. the main portion of the blank has been cut andscored, the

This:

pouring opening patch 48 is bonded to the inside faces of the panel's 25;"28'b'y means of an adhesive juncture 50 surrounding the lift tab 32. The juncture 50 includes an extension 51 which bonds the reclosure plug 39 to the inside face of the lift tab 32. The patch 48 is laterally centered on the panels 25, 28 and positioned with its score line 49 coinciding substantially with: the; transverse score line 30 of the blanlc, as illustrated in-Fig. 5.

A container: embodyingthe: present invention may be fully prepared for pouring in two simple steps. First, the pouring opening "31 .is exposedjbygrasping the lowerend lofthe'lift' tab" 32 and pulling up on the same'until the pouringiopening 31 is completely exposed, as indicated in Fig. 2. This automatically displaces the pouring lip 44 out of its dormant position. Second, the pouring lip 44 is then downfolded about the line 43 from its displaced position into its operative position as shown in Fig. 3. This may be accomplished by grasping. the lip..44 either with the fingers or .bythe use otany other suitable meansfor bend-. ing. ,the lip,.44 theremainderofi the. way toward. itsfully downfold'edlposition- Pouring may thereupon. be. effectively aceompli'shedlby incl-iningthe container to the desired angler Referring next .to=Eigs.; 61o v.l 2, inclusive, there: is shown a modifiedformot container,.-12.fland ablank A which also illustrativel'y embody the present invention. Ingeneral, the container 120 and. blank 120A are similar to the. container 20 and. blank 20A described earlier herein. Thus the container 120 comprisesa tubular body 121 having a topend. closure .122. surmounted by acentral rib 124. Flanking the rib.124 area pair of inclinedroof panels 125, 126fwhich respectively adjoin. front and rear. body panels 128, 129" alongcommon. scoreline 130 which'separates the-topclosure. 122.fr.om the-body 121. The roof panel has. asanitarilyprotected pouring opening .131 initially covered by a lift .tab 132 (Figs. 6 and 7). The pouring opening, 131 is... formed in. a. pouring opening ply 134 fixed. to the insideface of the-roof panel 125 and the body panel128. The lift tab 132 in. this instance is also integral with the. roof panel 125. and..the. extreme upper portion of'the body panel 128 but is substantially shorter, being definedby, spaced apart severance lines'135, 136 which terminate approximately at the-.score line. and inter-- sectthe. ends ofanincision line 138 in the upper portion ofnthecbody panel 1281. This construction results in a lift tab which hasaslightly protruding end. portion overhanging the. body panel.128-,, the. entire lift .tab, being substantially coplanar withsthe inclined. rooftpanel 125.

As indicatedin Figs. 6,.7-, lO-and 12, the pouring opening ply-.134. inthisinstance. happens to. be fashioned as aseparatepatch 140similar to the oneshown in Aldenapplication Serial No. 269,785, supra. The pouring; opening E31 isformed as a notchadjacent. the-upper. end ofthe' patch 140 and thelatter isfixed in centered relationon the inside faces of'the panels.125,..l28-with= its transverse score line 141: coinciding-substantially with. the-score line 130-0n the blank 120A. Attachment of the patch 140 to the blank is effected bymeans of-a'. substantially u-shaped adhesive juncture 142.

Thepouring. opening.ply-13.4 has a pouring lip 144 generally similar. to the: pouring. lip. 44 of the container 20. The lip 144 has a free separation edge145. and a pair of lateral edges 146 defined byincisionsin the ply134. Like the lip 44of the container 20, the, pouring lip, 144 is initially situated'in a dormant position coplanar with the pouring opening ply 134'.

Provision ismade in'the blank 120A and'in the container 120 for displacing the pouring lip 1'44 automatically as an incident to raising the lift tab 132 during'initial' opening of the container. As in the container 20, this is accomplishedby the use of a severable connection between tab 132. andLtheapouringli'p .14'4'situatedat a-point' spaced from the respectivechizngea-lines ofhotht the lip;144 andZthe-lifit tab.132.. In thisinsta-nce. however, theseverable: connectioncomprises a rupturablenadhesivejuncture 148 (Figs. 6, 7, 8 and 9) between the inside face of the lift amines tab 132 and the initially abutting face of the pouring lip 144. The juncture 148 may take a variety of shapes and in this particular case happens to be of circular form, being produced as by means of a small circular adhesive coated area 148A on the inside face of the blank 120A (Fig. 11). When the pouring opening patch 140 is affixed to the inside face of the blank 120A, the adhesive area 148A registers with a corresponding circular area on the pouring lip 144 and designated by the numeral 148B (Fig. 12). By reason of the construction just described, initial elevation of the lift tab 132 from the closed position represented in Fig. 8 toward its fully open position as indicated in Fig. 7 produces a resulting upward angular movement of the pouring lip 144 about its hinge line 143. As lifting of the tab 132 progresses, stress builds up in the adhesive juncture 148 until the connection between the lift tab 132 and the pouiing lip 144 ruptures completely. This permits the lift tab 132 to be elevated from the position of Fig. 9 to its fully elevated position indicated in Fig. 7 and leaves the pouring lip 144 in an upstanding condition out of the plane of the pouring opening ply 134. The user is thereupon reminded to complete the downfolding of the pouring lip 144 prior to pouring from the container 120.

Figs. 13 to 19, inclusive, illustrate another modified container and blank 220, 220A also embodying the invention. Since the container 220 and the blank 220A are somewhat similar to the other embodiments of the invention already described above, it will be unnecessary at this point to present a detailed description of their common features. Suffice it to say that the container 220 includes a roof panel 225 and an underlying body panel 228 adjacent thereto. The roof panel 225 serves as a pouring opening panel, being provided with a pouring opening 231 and an overlying lift tab 232. The pouring opening 231 is formed as an aperture in a pouring opening ply 234, the latter, in turn, being defined by a pouring patch 240. The patch 240 is adhesively bonded to the inside faces of the panels 225 and 228, the transverse score line 241 of the patch 240 coinciding substantially with the main transverse score line 230 of the blank and which separates the container body from the top closure. The pouring opening ply 234 has a manipulable pouring lip 244 initially disposed in a dormant position adjacent the pouring opening 231 and coplanar with the ply 234. The pouring lip 244 is generally similar to the pouring lips 44 and 144 of the containers described earlier herein but is situated somewhat lower in ply 234 and hinges substantially about the transverse score line 241 in the latter. In this instance, there is no reclosure plug associated with the pouring opening or the lift tab although such a feature may optionally be included in the container 220 if desired.

Automatic displacement of the pouring lip 244 incident to initial raising of the lift tab 232 is accomplished in a manner similar to that utilized in the container 120. Thus, there is interposed between the inner face of the lift tab 232 and the abutting face of the pouring lip 244 an adhesive juncture 248 (Figures 13 to 16) which is ultimately rupturable as the lift tab 232 becomes progressively elevated. While the juncture 248 may assume a variety of patterns, it happens to be circular in this instance and occupies the area 248A on the lift tab 232 and the area 248B on the pouring lip 244, these areas being in registration When the patch 240 is applied to the inner face of the blank 220A. In operation and usage, the container 220 behaves much as the other forms of containers previously described. However, it might be noted that when the pouring lip 244 is in its fully downturned position, its free edge overhangs the underlying body panel 228 to a substantially greater extent than the free edges of the pouring lips 44 and 144.
