1 11 Claims. My invention has to do with a type of folding carton from which the contents cannot be removed without tearing or mutilating the carton in such a way that tampering is indicated. Thus the ultimate user of the merchandise is protected from products which have been used and repacked and from the purchase of gods of one origin in packages indicative of a different origin. More specifically, my invention-has to do with cartons of a type comprising an' outer tubular shell with or without end closure means and an inner retaining means for the merchandise, which, when filled and inserted in the shell cannot thereafter be wholly removed therefrom without the production of telltale indications.

Cartons of this general type are not themselves new; but the proposals hitherto made have contemplated complex constructions which are relatively diflicult and expensive to make, which frequently require excess quantities of paper board,

and which sometimes are inconvenient to assemble. The primary object of my invention is the provision of a structure which is simpler,

-- more economical of board, less expensive to manufacture, and more convenient in use.

In some of the cartons hitherto suggested such as those intended for radio tubes or the like, provision has been made for a limited movement of the inner retaining means in the outer shell so that an end of the packed articlesi may be exposed for testing prior to sale. My invention is applicable to the provision of cartons having this capability.

, Again, it is an object of my invention to provide a carton having means to permit testing or partial inspection of the contents without permitting complete removal of the contents unless the package be destroyed.

These and other objects of my invention which will be set forth hereinafter or will be apparent to one skilled in the art upon reading these specifications, I accomplish by that certain construction and arrangement of parts of which I shall now describe certain exemplary embodidrawing wherein:

Figure 1 is a plan view of a blank for an outer carton member.

Figure 2 is a perspective view of the outer carton member in erected condition. Figure 3 is a plan view of a blank for an inner carton member.

Figure 4 is a perspective view 'of the inner carton member in erected condition.

ments. Reference is made to the accompanying v (c1. sea-e) Figure 5 is an end view of a carton containing a radio tube.

Figure 6 is a sectional view thereof taken along the lines 6-6 of Figure 5.

5 Figure 7 is a fragmentary sectional view showing the interaction of parts.

Figure 8 is a fragmentary sectional view showing the action of means permitting testing of the contents.

10 Figure 9 is a perspective view, with parts cut away, of another form of my invention.

In Figure 1, I have shown a blank for an outer carton member, characterized by body walls I, 2, 3 and 4 articulated together by the usual score lines. The'wall 4 is shown as having articulated to it, by the usual score line, a glue flap 5. The carton body thus far described is of the common tubular type, such that by folding operations along a pair of the score lines, and by the application of adhesive, 9, fiat tubular body may be formed with the glue flap 5 adhered to the wall I. This flat tubular body may be erected or squared up as shown in Figure 2. It is an advantage ofmy invention that my outer carton-mem bers, and in some forms my inner carton members also, may be tubed and glued on the ordinary carton making machinery.

I have shown my blank in Figure 1 without end closures, and because of the inner carton member which will hereinafter be described, end

closures on the outer carton member are not required for many uses. But end closures may be provided by forming seal-end or tuck end closure flaps of any of the known types on the ends of the body walls, as will readily be understood. A set of tuck-end flaps is illustrated in Figure 9 of the drawing. 1

I The principal objects of my invention are simply and inexpensively achieved by articulating to the glue flap 5 a glue flap extension I, by means of a score line as shown, and by causing this glue flap extension to interact with the inner carton member as will hereinafter be explained. The width of the glue fla extension may be widely varied, and may be increased to nearly the difference in width of the glue flap and the wall I, if desired. In length, the glue flap extension may be equal to the interspacing of the end walls of the inner carton member, or where some permissive movement of the inner carton member in the outer carton member is desired,

its length may be less, as will hereinafter be excarton outer member. One form 01' inner member is shown in Figure 3, and comprises end walls 8 and 9, each articulated by a score line to an intermediate side wall In, and each having articulated to it by a score line, a member ll or 12 designed to form part of the opposite side wall, and having interlocking means as shown, or other suitable attachment means whereby the inner member may be folded about the contents for the carton, and formed into a tube. For some sorts of contents, as for example radio tubes or incandescent bulbs, it may be desired to provide perforations l3 and in the end walls oi the inner carton member, for the top portion and for the base or contact prongs of the lamp or tube. Also for such articles it is frequently desired to have the end walls of the inner carton member lie inwardly oi the ends 01 the outer carton, as

accuses member a line of score l8, common to all 01! the walls and the sealing flap and located approximately in the plane of the wall 8 when the package is assembled as in Figure 6. The prolongations of the score lines articulating the walls of the outer carton member, where they extend beyond the score line 18, may be made as lines of weakening 59, such as lines of minute perforations. When it is desired to test the contents of the carton, the outer carton member may be severed or split along these lines up to the score line H. When this has been done, the end portions of the walls oi the outer carton member may be bent outwardly as shown in dotted lines at in Figure 6. The guide flaps l8 may likewise be bent outwardly as shown. Thus access is givan to the contact prongs oi the radio tube as will be clear.

Instead of providing for access or testing in this way, I may merely provide for a limited movement of the inner carton member in the outer carton member-not such a movement as shown in Figure 6, in which event guide flaps ll may advantageously be articulated to end wall 8 and guide flaps 16 to end wall 49, by suitable score lines. The inner carton member is shown in erected form in Figure 4.

In Figure 9 I have shown another modification oi! the inner carton member in that it is in the form of an adhesively secured tube. The end walls 8a and 9a are connected by an intermediate wall ills. A complete wall I la is articulated to the end wall to, and the end wall to bears a glue flap l2a. This type of inner carton member may be folded and glued in flat tubular form on the ordinary cartoniolding and gluing machinery.

In my carton, when the sealing flap extension I is bent slightly inwardly as shown in Figure 2, its resilience tends to maintain its position. When the inner carton member has the contents placed within it, and is inserted into the outer carton member," the glue flap extension i may be temporarily pressed back so that it lies against the wall I or the glue flap 5, to allow one 01 the end walls of the inner carton member to pass it. But if the inner carton member is properly inserted, with its side walls Ill and H, II parallel to and lying along the walls 2 and 4 of the outer carton member, as soon as the inner carton member attains its proper position, the glue flap extension 1 will again spring inwardly as far as the contents of the box will permit, and will lie between the end walls 8 and 9 of the inner carton member. This relationship is shown in Figures 5 and 6, where a radio tube I1 is indicated within the inner carton member, its-respective end portions extending through the perforations l3 and 14.

If the length 01 the sealing flap extension I is approximately equal to the interspacing between the end walls 8 and 8 or the inner carton member, the inner carton member can not be moved in either direction without tearing and destruction either of the glue flap extension I or of some portion of the inner carton member. The contents thus cannot be removed from the carton and used, and thereafter replaced therein and sold, without the carton itsel! showing that it has been tampered with. It may, however, be desirable to permit the testing of the contents of the carton without their removal. It will be noticed in Figure 6 that the contact prongs of the radio tube extend below the wall 9. In order to make them available for testing purposes, I may provide in the blank for the outer carton would permit removal 0! the contents, but a suiflcient movement. say, to bring the wall 8 down approximately to the lower end of the outer carton member. This is accomplished merely by shortening the length of the glue flap extension 1, say by removing the portion marked la in Figure 1. Such a structure and its method of operation is shown in Figures 7 and 8. By depressing the inner carton member so that the end wall 9 comes about to the level of the end of the outer carton member, the guide flaps l6 may be bent back, and the tube tested. Yet it is still not possible to remove, reuse, and replace the contents of the carton. Alter the testing of the contents, the inner carton member and tube may be raised to their original position.

In Figure 9 I have shown a general utility carton for use under circumstances where it is essen= tial that the purchaser know that the carton contains its original contents, and where positive indication oi tampering is required. I have allready described the inner carton member shown in this figure. The outer carton member has walls, a sealing flap and a sealing flap extension similar to that shown in Figure 1, excepting for size and shape, which may be varied as desired. I have indicated an end closure on the outer carton member, comprising flaps 2! and 22 articulated respectively to walls 3 and i, and a flap it which has a tuck end 24, articulated to wall i. The other end of the carton body may have a similar closure, a seal-end closure, or any other suitable closure.

Wide modifications may be made in the construction, dimensions and mode of use of the elemerits which I have described. By way of exemple, if the glue flap extension 7 is no wider than the glue flap 5, it need not be bent entirely over on the glue flap 5 prior to the insertion of the inner carton member. The contents of the carton will then usually prevent the glue flap extension from returning to a position at an obtuse angle to the glue fla'p 5. This makes it more diflicult to tamper with the carton for the improper removal of its contents because an instrument cannot readily be used to depress the glue flap extension I. The glue flap extension I may be configured as desired, or may be formed in a plurality of articulated sections. It also may if desired be made to coact with other parts of the inner carton member than or in addition to the walls 8 and 9, such as extensions on the wall ill.
