As an example, the carton is particularly well designed to contain carry-out foodstuffs in a manner whereby once food has been placed in the carton and the carton has been closed, the carton may be readily handled in one hand without excess flexure of the carton rendering it difficult to be handled.

In addition to the structure of the. carton providing a container which may be readily handled, the top panel section of the carton includes novel tuck and lock tab portions that may be readily displaced into the desired positions for locking the top panel of the carton in a closed position after food has been placed therein. Further, the carton is constructed in a manner whereby it may be stored in a flattened condition and thus stacked prior to being filled. Also, the structure of the carton is such that it may be readily unfolded from its flattened condition for placing foodstuffs therein.

In addition to the carton being readily handled after being filled and closed, being readily closable in a manner locking the top panel of the carton in a closed position after foodstuff has been placed within the carton and being readily stackable inflattened condition prior to its use, the blank from which the carton is constructed includes three main sections which are folded relative to each other during initial forming of the carton after the blank has been cut. Two of the main sections of the blank have adhesive means thereon and the only adhesive joints of the carton are formed as the three main sections of the blank are folded 180 relative to each other into stacked superposed relation. Once these three main folds of the blank have been made in order to form the three adhesive joints of the carton, the carton is complete and thereafter needs only to be unfolded from its flattened condition immediately prior to its use.

The main object of this invention is to provide a fold-up container or carton formed of a single struck sheet.

Another object of this invention is to provide a single struck sheet for forming a carton including three main relatively foldable sections thereof which are folded 180 relative to each other into superposed stack relation after apair of minor sections of the sheet or blank are folded 180 in order to form a completed flattened carton for ready subsequent unfolding to form the desired carton.

Still another object of this invention is to provide a sheet or blank in accordance with the preceding objects for forming a carton in which only three adhesive joints are utilized and which joints are automatically accomplished during the folding of the two minor sections and the three major sections 180 relative to each other.

Still another important object of this invention is to provide a carton which may be readily formed from a folded blank in a minimum of time.

Another object of this invention, in accordance with the immediately preceding object, is to provide a carton, which when formed, includes a swinging top panel including tuck and lock tab portions that may be readily displaced into position locking the top panel of the container in the closed position after foodstuffs have been placed in the container.

Another important object of this invention is to provide a container, which when closed about foodstuffs contained therein, may be readily handled in one hand without the'container or cartonexcessively flexing.

A final object of the invention is to provide a carton in accordance with the preceding objects which will conform to conventional forms of manufacture, be of simple construction and easy to use so as to provide a device that will be economically feasible, long lasting and relatively trouble free to handle.

With the above and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claimed subject matter, and the several views illustrated in the accompanying drawings.

FIG. 1 is a plan view of the extended blank from which the carton of the instant invention may be formed.

FIG. 2 is a plan view of the blank after the center pair of opposite side sections thereof have been folded inwardly over the center section and one of the main end sections has been folded over the center section of the blank.

FIG. 3 is a perspective view of the completed carton.

FIG. 4 is a further perspective view of the completed carton as seen from a different angle.

FIG. 5 is a perspective view of the completed carton with the cover or top panel thereof swung to an open position.

FIG. 6 is an end elevational view of the carton.

FIG. 7 is a rear elevational view of the carton with the rear half of the carton removed and one of the lock tabs of the top panel of the carton illustrated in an unfolded position in phantom lines.

FIG. 8 is a top plan view of the carton with the top panel thereof removed.

Referring now more specifically to the drawings, the nu meral 10 generally designates the blank from which the carton of the instant invention may be formed. The blank 10 includes three main sections A, B and C defining an outer top section, a bottom section and an inner top section.

The outer top section A includes a top panel 12 including a front portion 14 and a rear portion 16. The

portions

14 and 16 are separated from the top panel 12 by fold lines 14' and 16'. In addition, the top section A includes a top tab 18 and a rear panel upper extension 20 which are separated from the

portions

14 and 16 by fold lines 18 and 20'. The tab portion 18 has a pair of notches 22 formed in its free edge portion defining a tuck tab portion 24 between the notches 22. In addition, the opposite ends of the tab 18 include lock tabs 26 separated from the opposite ends of the tab 18 by means of fold lines 26'.

The main section B is separated from the rear panel upper extension 20 of the main section A by means of a fold line 28 and includes a central bottom panel 30. The center section 8 further includes bottom panel front and

rear extensions

32 and 34 separated from the bottom panel 30 by means of fold lines 32' and 34' and the section B further includes front and

rear panels

36 and 38 separated from the

extensions

32 and 34 by means of fold lines 36 and 38'. The fold line 28 separates the rear panel 38 from the rear panel upper extension 20 and it will be noted that all of the previously referred to fold lines extend transversely of the blank 10. However, the section B further includes

opposite end panels

40 and 42 separated from the opposite ends of the bottom panel by means of fold lines 40 and 42' which extend longitudinally of the blank 10 between the opposite ends of the fold line 28 and the opposite ends of a fold line 44 which separates the section B of the blank from the section C of the blank. In addition, the opposite ends of the

end panels

40, 42 include corner tabs 46 defined between fold lines 46' and 46" and tuck tabs 48 are defined between each fold line 46' and the adjacent end of the corresponding longitudinal fold line 40 or 42'. Further, each of the tuck tabs 48 has an adhesive coating 50 thereon.

The section C includes a longitudinal slit 52 on whose opposite sides a pair of

inner end panels

54 and 56 are defined. Also, the section C includes a pair of

transverse slits

58 and 60 with whose center portions the opposite ends of the slit 52 intersect. The section C further includes a pair of short longitudinal fold lines 62 and 64 with a pair of shallow U-shaped slits 66 disposed at opposite ends of each of the fold lines 62 and 64 and

transverse fold lines

68, 70, 72 and 74. The fold lines 62 and 64 and the adjacent ends of the

fold lines

70 and 72 define a pair of

inner top panels

76 and 78 outwardly of the

inner end panels

54 and 56 and between the

fold lines

70 and 72. In addition, a pair of inner top panel

rear extensions

80 and 82 are defined between corresponding ends of the fold lines 72 and 74 outwardly of a pair of

diagonal fold lines

84 and 86 communicating with the opposite ends of the slit 58 with the adjacent ends of the fold lines 62 and 64. Also, a pair of rear

inner panel tabs

88 and 90 are defined between the opposite ends of the slit 58 and the opposing portions of the fold line 74 and the fold line 74 defines an inner rear panel upper extension 92 extending across the free edge of the section C outwardly of the slit 58 and the fold lines 84.

The end of the section C adjacent the section B includes inner top

panel front extensions

94 and 96 corresponding to the

extensions

80 and 82, a front panel upper extension 98 corresponding to the rear panel upper extension 92, a pair of front

inner panel tabs

100 and 102 corresponding to the

tabs

88 and 90 and also a pair of opposite side inner end

panel front extensions

104 and 106 defined between the

fold lines

68 and 70 on opposite sides of the slit 52. Of course, the free end portion of the section C also includes inner end panel

rear extensions

108 and 110 corresponding to the

extensions

104 and 106.

From FIG. 2 of the drawings it may be seen that the under surface of the inner rear panel upper extension 92 includes a coating 112 of a suitable adhesive material. And it will be further observed from FIG. 1 that the section C includes a pair

oflock tab openings

114 and 116.

With attention again invited to FIGS. 1 and 2 of the drawings, it may be seen that in initially folding the blank the opposite sides of the section B are folded upwardly and inwardly along the fold lines 40' and 42 to the dotted line position D and E. Of course, the adhesive 50 adheres to the opposite ends of the front and

rear panels

36 and 38 to retain the

end panels

40 and 42 as well as the corner and tuck tabs in folded positions. Then, the section C is folded upwardly over the section B exposing the adhesive layer 112 after which the section A is folded over the section C so as to adhesively secure the rear panel upper extension over the inner rear panel upper extension 92. At this point, construction of the folded container is completed and it will be appreciated that the folded container, except for the opposite side portions of the section B which comprise four thicknesses, is only three thicknesses thick.

The completed container is illustrated wholly or in part in FIGS. 3-8 of the drawings. In erecting the container or carton from the finally folded condition of the blank 10, the section A is first unfolded to the open position after which manual pressure may be applied on the areas of the blank in which the fold lines 28 and 44 are formed in order to urge these areas toward each other. This pressure will elevate the center of the section C relative to the center of the section B and the adjacent edge portion of the

inner end panels

54 and 56 are swung downwardly along the fold lines 62,64 which will also cause folding along the

lines

84 and 86 and the corresponding unnumbered lines at the opposite ends of the

inner end panels

54 and 56. The adjacent edges of the

inner end panels

54 and 56 are swung downwardly until the

inner end panels

54 and 56 are vertically disposed with their free edge portions abutting against the upper surface of the bottom panel 30 and the

bottom panel extensions

32 and 34. As the

inner end panels

54 and 56 are swung downwardly, folding will occur along the fold lines 68, 70, 72 and 74 so as to form generally trough shaped end walls opening toward each other. In addition, as the free edges of the

inner end panels

54 and 56 are swung downwardly and the inner

top panels

76 and 78 are elevated above the section B, the rear and front panel

upper extensions

20 and 98 will be unfolded relative to the rear and

front panels

38 and 36 and the

end panels

40 and 42 will be unfolded from the opposite sides of the bottom panel 30. Also, the comer tabs 46 are unfolded along fold lines 46' and 46" and are slightly bowed at the adjacent opposite end portions of the fold lines 36' and 38' as the

inner end panels

54 and 56 reach their fully erected positions. The carton, which is generally designated by the reference numeral 120, is now fully erected and may have the desired foodstuffs placed therein after which the section A may be swung from its open position illustrated in FIG. 5 of the drawings over the inner

top panels

76 and 78 and have the tuck tab portion 24 inserted behind the central portion of the front panel upper extension 98.

Thereafter, the lock tabs 26 may be folded downwardly and inwardly under the opposite ends of the front panel upper extension 76 and engaged in the

lock tab openings

114 and 116. In this manner, the top panel 12 of the carton is securely fastened in a closed position.

With attention now invited to the comer portions of the carton 120 illustrated in FIGS. 3-5 of the drawings, it will be seen that the corner tabs 46 and the

end panels

40 and 42 of the blank 10 back and brace the outside surfaces of the

inner end panels

54 and 56 as well as the inner end panel rear and

front extensions

108, 110, 104 and 106. Further, it will be noted that the opposite ends of the top panel 12 overlie and are braced by the inner

top panels

76 and 78 of the section C when the top panel 12 is in its closed position.

In review, the blank 10 is rectangular in configuration and therefore a plurality of the blanks 10 may be formed from a single roll of panel material with very little wastage. In addition, after the adhesive 50 and 112 has been placed in position, all that is necessary to form the collapsed container is to fold the opposite side portions of the section B disposed outwardly of the fold lines 40 and 42 inwardly and over adjacent marginal portions of the section B. Then, the section C is merely folded over the section B and the section A is folded over the section C. Further, the carton 120 may be readily formed from the folded blank 10 and the top panel 12 may be readily secured in the closed position by means of the tuck tab portion 24 and the lock tab 26.

While preferred forms and arrangements of parts have been shown in illustrating the invention, it is to be clearly understood that various changes in details and arrangement of parts may be made without departing from the spirit and scope of this disclosure.
