CARTGN Filed March 17, 1958 Patented Apr. 4, 1939 CARTON Charles S. Reid, Philadelphia, Pa., assignor to Container Corporation of America, Chicago,
11]., a corporation of Application March 17,
' charactermentioned. Thebox chosen for illustration of the invention is well adapted for the packaging of candy mints and the like.
Packages used for dispensing small quantities of a commodity such as a number of small candies are usuallyof a size easily fitting within a person's pocket and ordinarily must be cheaply constructed in order to maintain a reasonable margin of profit both for the box maker and for the candy manufacturer. on the other hand the box should sibility to the contents for surreptitious and not be so cheaply made as to permit ready acceswrongful removal thereof'and should be of such character of construction as to give the purchaser reasonably easy access to the commodity. Furtherore, since the purchaser may use only a few of the commodity items at a time, the box should be so constructed as to permit it to be opened and closed a multiple number of times, and, when closed, to be and. to. remain relatively tightly closed so that dirt may not enter and the con-' tents may not spill out.
Accordingly, one of the principal objects of the invention is to provide a simple, strong and economical construction for boxes of the character described which will be relatively tamper or pilferproof, which may be easily and'quickly opened for access to the commodity it contains, and which may be closed and reopened as many times as necessary, each closing being secure and not only preventingspillage of the contents but also preventing the entry of dirt. 1
Another important object is to provide a novel type of closure for a box and including means whereby tampering, unauthorized opening or pilferage of the contents may be readily detected.
' Still another object is to provide a box of such construction as will permit the same to be formed from blanks cut from a single piece or sheet of material, the construction also being such that the box blanks may be shipped in the blank (fiat) condition to a place of use and there set up or folded and filled with the desired commodity.
Many other objects as well as the advantages and uses of the invention will be or should become apparent and understood after reading the following description and claims, and after viewing the drawing in which:
Fig. 1 is a perspective view of a candy mint Delaware 1938, Serial No. 196,348
box illustrating one preferred embodiment of the invention. 1 I
Fig. 2 is a perspective view of a fragment of the box of Fig. 1 showing the appearance thereof after being opened, and
' Fig. 3 is a plan or developed .view of the cut and scored box blank as it appears bef o'rebeing folded and sealed into box form. 7 M
The generally rectangular *box of Figs. 1 and 2 is formed by folding the blank Fig. 3, which is cut from a single and continuous sheet of material, such as paper-board, and appropriately scored, either at the time of cutting or thereafter. The dotted lines l, 5, and 6 indicate score lines which, together with edge 1, define what may be termed a bottom section or panel 8. A marginal portion 3 integral with the panel 8 along one side edge thereof may be lapped inside or outside of a side wall panel or section to be described, while integral with one end of panel 8 is an end wall or end closure panel or section i set 01f from a closure tuck fiap l2 by a score line l3.
Score lines 6, it, it and it define between them a side wall section or panel ll; score lines It,
l8 and i9 and edge 2i define a top section or panel 22; and score lines i3, 23 and 2%, together with edge 25, define side wall section or panel 26. Integral with one edge of top panel 22 is an end wall or end closure panel or section 27 set ofif from a closure tuck flap 2% by a score line 23. At one (either) end of each of side wall sections or panels I! and 26, but at those ends thereof which are at the same end of the box, is a closure fiap 3|. At the opposite end of each of panels l1 and 26 is a long closure flap 32 which has been weakened, as by perforation or partial cutting, along a transverse line 33. The edge 2| of panel '22'may be notched centrally as shown at 34.
Infolding the box into shape from the blank, it is first folded along score, lines 4, 6, l6 and Hi to lap the marginal portion or flap 9 inside or outside of the panel 26 to which it may be glued or otherwise secured. Next the end closure flaps 3| are folded down over the adjacent open end and toward one another and the end wall panel 21 and tuck fiap 28 are bent on store lines l8 and 29 and the fiap 28 is tucked into the end of the box between the inside face of panel 8 and the adjacent edges of end flaps 3|. The tuck fiap or tongue 28 may be secured both vto the bottom panel 8 and to flaps 3| by glue or other adhesive or by other means, or the flap 28 may be secured only to the panel 8. The box is now ready to be filled or loaded from its oneremaining open end.
. flaps 32.
After the box has been filled, the end closure fiaps 32 are bent on score lines It and 23 and folded over the end of the box toward and into lapping relationship with one another and secured to one another by a spot or more of glue or other adhesive as indicated at 35. Preferably each of flaps 32 is of a length to lap the other to a substantial extent so as to provide a substantial amount of rigidity between them when they are glued or otherwise secured together. Following the securing of flaps 32, the end panel Iland tuck flap or tongue l2 are bent on score lines 5 and I3 and thefiap i2 is tucked into the box end between the inner face of top panel 22 and the adjacent edges of flaps 32. Preferably, the flap I2 is not secured to the top panel 22 nor is the end panel II secured to the The flaps 32 when secured to one another provide ample security against pilferage, and the flap l2 may be held in position merely by friction to provide ease and quickness of manipulation for opening.
When a purchaser desires to open the box he pulls out the flap l2, using the finger grip surface on the flap provided or made available by the notch 34. This operation exposes the lapped closure flaps 32, which are then torn away together at the weakened lines 33 and discarded, leaving the box contents readily accessible. If the box contents are not immediately used or exhausted, the purchaser may close the box, using the remaining stub portions 32a of the flaps 32, the flap l2 and end wall panel II for the purpose.
The construction described not only provides a box which is relatively simple and economical to manufacture and use, but one which is substantially pilfer and tamper proof to the extent that unauthorized entry is instantly detectable. The destruction of the seal, that is, removal of the end portions of flaps 32, in opening the box for accessjto the contents, does not destroy the continued usefulness of the box insofar as protection of the remaining contents from dirt and spillage is concerned.
The box may be constructed with a frangible Seal at each end instead of one end, and the scheme may be applied in other ways to boxes of various other shapes, sizes and types. Many other'variations, modifications and applications of the invention may be devised within the spirit of the invention and the scope of the appended claims.
