DISPENSING CONTAINER Filad Feb. 19, 1962 2 Sheets-Sheet 2 INVENTOR. Lew/1s E. Kirkwood HTTORNE Y Filed Fein-.19, 1962, Ser. No. 173,978 l6 Clams.- (Cl. 229-61) Thisinvention generally relates toa dispensing contalner or cartonfor thin sheet material and, more particularly, relates to an improved dispensing container which makes use of a perforated and cut seam positioned in a novel manner such that the container can be readily opened by a pulling action.

It has been conventional in designing cartons for elongated rolls of thin sheet material, such as a roll of polymeric lilm,-to use similarly elongated rectangular trunklid style folding cartons. kA common disadvantage of atento such .trunk-iid style cartons is the burdensome degree of ditliculty the user experiences in attempting to open such a carton construction preparatory to. usingthe product it contains. Where glue `spotsand perforationsA have been used previously, they havenot allowed the carton to be correctly opened without a substantial measure of diiculty, or without tearing, m'aiming, or otherwise defacing the carton itselt. y.

Accordingly, it is an object of the present invention to provide a trunk-lid style carton which may be readily and easily opened. v

It is a .further object of the present invention to pro videv a trunklid style f carton` which can be readily and easily opened upon application of pressure no matter how inaptiy that pressure is applied. v

Still another object of the present invention is to provide anovel perforated seam arrangement for ltrunk-lid style cartons-which can be easily opened without tearing, maiming, or otherwise defacing the carton itself.

' Briefly -then, the present invention relates to a novel trunk-lid style carton wherein a perforated v seam is formed betweenthe front flange or face of a lid member and a front panel of the body of the carton such that insertion of lingers vor other-,objects under the front flange of the lid results in an openingof the carton when a pulling 4pressure is applied.

Yet additional vobjects and advantages ofthe present invention, and its numerous cognate benelits and features are even more apparent and manifest in and by the vensuing description and specification taken in conjunction with .the accompanying drawing in which wheresoever possible-like characters of reference designatecorresponding material and parts throughout the several views thereof, in which: A

FIGURE l is a plan view of a blank as cut, scored and perforated-and from which a trunk-lid'style container is formed;

FIGURE 2 is a top plan view, partially broken away, of a container formed from the blank ofFIGURE l, and including aroll ofsheet film therein;

FIGURE 3 isa front elevational view, partially away,'of the container of FIGURE 2;

FIGURE 5 is a cross-sectional view of the container of FIGURE 2 taken along the reference line 5-5 thereof; and

FIGURE is a cross-sectional view similar to FIG.- URE 5,*only taken after the lid member of the container is opened.` v

Blank 10 for a trunk-lid style container can be formed of any suitable material, as for example, paperboard, berboard,vor any other container board material. Re-

broken 'ice ferring more particularlyto FIGUREl, :box portion 12' of carton or container 14 (FIGURE 2.) comprises a bot 3 tom panel 16 having joined thereto, along score line 123,:j a front panel 20 and, along another score line. 1S, a rearj panel 22. Also connected to thebottom panel, front'l panel,and rear panel, are oppositeend flaps 24, 26, and 28, respectively, for forming end panels 30 (FIGURES `2 and 4) of :the container 14. ,These laps arev connected" j to their adjacent panels at additional score lineslS.y A

lid member 32 of the blank 10 is 'formed of a top panel 34 hingedly connected to rean panel 22 along yet another i vscore line 18. Also'forming parts ofthe lid member 32 are .opposite side anges 36 and front flange 38, each connectedto top panel 34 along jother score lines 18. Joined on opposite sides of front 'llange 38 are flaps 40 and elongated front Aflap 42, also joined by ascore line 18.

In forming the container 14, front ilap 42 is adapted to be reversely folded upon front flange 38 such that the Aperforated lineV 44 generally Acoincides with thejportion I illustratedl by vimaginary linel 46..-formed on the front flange. It is then the intent that the portions 48 and 50 of the `front liap and front flange,.respectively, kbe glued or otherwise secured-together. Container 14 is further assembled by and 428 are glued or otherwise secured to the inside of .the flap 24 and ilaps 40 are gluedto. the'inside of side flanges .36, withcorresponding: score lines .coinciding.,

To complete the container 14, lip "-52 of front llap 42 is brought into engagement with front panel 2) such Ythat the surface of lip 52 opposite fromthat showing in FIG- URE 1 is aligned with a portion V54 f(deiined by imaginary line SS) as'indicated on front panel-20. The mating surfaces of lipr52 and portion $4 are-.then glued vtogetherto form a sealed carton as illustratedin FIGURES 2, to

5 described in more detail hereinafter. Itis understood that in employing a tube style carton'blank as illustrated in FIGURE 1 that the previouslyformed carton blank is normally erected by a machine -.(not shown and not forming a part ofthe present invention) which inserts the product or roll of lm into thevcarton and then folds land glues the end flaps, this resultingin. a complete packasel FIGURES 2 to S illustrate the complete carton 14.con taining lid member 32, end panels, 30, and bodyportion 12. Lid member 32 is illustrated asincluding atop rectangular panel 34 generally of the same, although somewhat larger, configuration as the body portion 12. Extending downwardly towards the bottom of the carton 14 are the opposite end llangesor sides 36 and front ange or side 38 of the lid member 32. Body portion 12.contains front panel 20, opposite end panels 30, bottom panel 16, and rear panel 22. Contained along the gluing or otherwise securing lip 52 o'filap 42 to the upper portion 54 of front panel 20. Thus, perforated seam 44 can be easily opened by asserting a pulling force or pressure in an outwardly direction-trom the carton under the front llange 3Sagainst portion 48 to separate the latter from lip 52. The tearing offperforated seam v44%' can be accentuated by providing l' asubstantial cut line 64 (FIGURE 1) along the seam ifdesired. Instead. of having to push in to separate .a perforated seam as` is common in `other devices, carton 14 ofthe present invention merely requires a pulling action or pressure which patented Apr, 21, 1964 folding along@` each of the remaining score lines v18 vauch that ilaps26,

-is effective in opening the carton easily no matter how thermore, the securing of the subject components together in this manner results in a sealed trunk-lid style carton forfits enclosed product from the time the product is packaged until it is opened by the ultimate consumer.

Carton 14, after it is opened, is illustrated in FIGURE 6 to show how the film 60 is removed therefrom. Obviously, it is brought out over the top of edge 66 on lip 52 and down `around the blade 58 along which it can be readily torn after the desired quantity of iilm has been removed.

While certain representative embodiments and details have been shown for the purpose of illustrating the invention,.it will be apparent to those skilled in the art that lvarious changes and'modications can be made therein without departing from the spirit and scope of the invention. y

Accordingly, what is claimed as new is: l. A dispensing container comprising a hollow body 4. The container of claim' `1" wherein said flap and said front flange are secured together so as to forni a double thickness to resist tearing upon the application of pressure.
