end wall of the carton. Securing flap portions 17 to 22 inclusive may be provided for securing all of the various portions of the carton together in the completed article in accordance with the usual practice. It will be understood, of course, that these various portions are dened from each other by such means as scores 23 to 31 inclusive and by llines of severance 33 to 36 inclusive.
In the particular blank shown, in forming it into a carton, the various flaps 17 to 22 inclusive will preferably, of course, be positioned on the interior of the carton so as to-present a smooth exterior surface therefor. It is particularly desired to call attention to the fact that the flap 21 in the flnis parallel to the score 27 its central portion is curved outwardly as at 43 for a purpose which will presently be apparent. It may be noted, and is to be lso interpretated in the following claims, that the line of severance 40 may be either complete or of an interrupted nature.
That portion of the surface 13 which is to co'- operate with the ap 21 in the nished carton is provided with an aperture 44 and a line 45 of perforations which follow the saine general shape as the line of severance 40 except that its end c portions 46 are spaced apart a slightly greater amount than the end portions 42 and its main portion, which extends parallel to the adjacent edge of the surface 13, is spaced inwardly from the edge a slightly greater amount than the main portion of the line of severance 40 from the score v 27, the reason for all of which will be fully de-v Aperforations is spaced outwardly of the corresponding end portion 42 of the line of severance 40. It will also be observed that the aperture 44 substantially aligns itself with the curved portion 43 of the line of severance 40 and that the corresponding edge of the opening is spaced inwardly of the portion 43. Consequently, the portion of the flap 2l within the part 43 of the line of severance 40 adjacent the opening 44 projects inwardly from the edge of the box relative to the corresponding edge of the opening 44 and under the outer wall of the carton around the cor,- responding margin of the opening 44 as best indicated in Fig. 5, while over substantially the remaining'portion of the box the line of severance 40 is closer to the edge. 55 than the line of perfora tions 45 and consequently that portion of the outer wall of the carton within the line of perforations 45 overlaps the corresponding portion of l theflap 21 outside of thel line of severance 40, as
suggested in Fig. 4. y
With the carton secured together as illustrated in Fig. 2, and supposing that it encloses a material of some suitable description, when it is desired to withdraw Yal1 or part of the contents of the carton, pressure by any suitable means may be applied along the line of perforations to rupture the wall 13 along this line, and then a ngernail may be iserted into the opening 44 and forced outwardly towards the edge 55 of the carton between the wall portion 13 thereof and the ap portion 21 thereof, and then urged outwardly so as to completely break the seal between the two parts. The curved portion of the ap 21 immediately within the curved portion 43 of the line of severance 40 thereof and which is underlying the opposite margin of the opening 44, will resist complete severance along the line of perforations as will also the glue vholding the ap 21 to the wall 13. However, inasmuch as the glued area resisting this movement is relatively small it will readily give way, and the curved underlying portion of the flap 21 will spring back to allow that portion of the wall 13 and the ap 21 between the line of perforations and the edge 55 to be bent upwardly about the edge 55, thereby forming an opening in the carton, and also forming a closure flap, generally indicated at in Fig. 3, for such opening.
It will be observed that except at the central portion, the outer wall portion of the flap 60 projects beyond the inner wall surface thereof so as `to form a shoulder 6l, best indicated in'Fig. 4,
and that the cooperating surface of the carton, when the ilap is in closed position, is provided with complementary stepped surfaces, forming a shoulder 63 complementary to the shoulder 61, so that these stepped surfaces or shoulders form a seal for the edge of the flap when the ap is again closed. It will be observed that the curved portion of the flap portion 21 now forms a tab 62 the margin of which forms a shoulder 64 which underlies the cooperating portion of the cooperating shoulder 69, best indicated in Fig. 5, when the flap is in closed position, and the tab 62 thus provides a means for latching the ap 60 in closed position and maintaining the stepped surfaces of the ap 60 and carton in contacting relation. In closing or opening the flap 60 it will be apparent that lit will be necessary to spring the tab 62, or the cooperating Wall of the carton, or both, but this is relatively easily accomplished.
From the above it will be apparent that there are only two points along the entire free edge of the flap 60 where an overlapped joint is not obtained when the flap 60. is in closed position and after it has once been opened, and these two points occur where the line of severance 40 in the completed carton intersects the line of perforation 45. Accordingly, it will be apparent that the construction above described provides a cart0n in which a discharge opening may be readily formed, and when once formed may be closed in a simple and'efcient manner and so securely in nature as to prevent insects or the like from entering the carton along the edge of the ap.
A carton of the above described type is ideally suitable for the reception of material in rolled form, a common example of which, for instance, is rolls of absorbent cotton such as are commonly found on the market. An adaptation of the present invention for the purpose of containing such roll is indicated in Fig. 6 in which is illustrated a carton 65 of the same general construction as above described and having an opening 66 therein the severed end pushed back through the opening t 66 and theflap 67 closed.
Another use of the carton is illustrated in Fig. 7 in which a carton is indicated generally as at 'I0 and which may beconstructed in a manner similar to that above described and provided with a discharge opening 71 and a closure flap 72.. In this casethe carton is shown as containing thin wafer-like objects 'I3 which may be in the nature of cookies, crackers or other similarly shaped objects.
It will also be apparent that-such cartons 'are admirably suitable for use in connection as containers for bulk materials' of a pourable nature such as various breakfast foods, soap ilakes, salt or o'r anyothe'rdry material capable of a pouringeffect. In such a case' the dimensions of theopening provided in the carton therefor may of course be varied to best suit the conditions to Awhich.' the -carton is'to be put and the flap, of course, madeof a corresponding size and dimensions in accordance with the invention herein disclosed to effect a closure for such opening.
Formal changes may be made in the'speciflc embodiment of the invention described, .without departing from the spirit ofthe broad invention,
.the scope of which is commensurate with the appended claims,
1. In combination, a carton having a fixed wall provided with an opening therein, at least a por tionof-the margin of the wall f said carton' dening said opening being stepped with the outer surface of the wall overhanging the step, and an outwardly swingable closure for said opening l having marginal portions stepped for cooperative engagement with the rst -mentioned stepped,
margins.y
2.
