, 1 Claim. (Cl. 22 9--51) This a continuation in part of my copending application, Serial No. 193,936, filed March 4, 1938.

My invention relates to cartons or boxes made e from fibrous sheet material; and it is among the objects of my invention to means for opening the same.

Another object is to provide a carton originala reclosable conprovide improved tainer. 7

Another object is to provide acarton having a tear strip encircling the body thereof for disconnecting a part of the carton.

Still another object is to provide a modified carton construction having a tear strip removable to form a hinged cover.

A further object is to provide another modified carton structure in which a tear strip istremovable to form a pouring opening.

Tl'ieinvention possesses other objects and features of advantage, some of which, with the foretending across one wall only to form a pouring o In greater detail, and referring particularly to Figure 1 of the drawing, my carton or box preferably comprises a body having side walls I, end walls 2, and closure fiaps 3 at the top and bottom of the carton, all formed from a single blank of fibrous sheet material. The side and end walls of the carton body are preferably joined bya gluing strip 4; and in the finally closed position the flaps 3 are glued together to completely seal the carton. A tubular liner Gof relatively stifl fibrebcard ,is preferably arranged in the carton coextensive with the side and end walls. This liner is preferably formed from a single blank of material suitably scored and held in tubular shape by a gluing strip 1. The liner. is propoF going, will be set forth in the following description of my invention. It is to .be understood that I do 'not limit myself to this disclosure of species of my invention, as I may adopt variant embodiments thereof within the scope of the claim.

Referring to the drawing: r v Figure 1 is a perspective view of a carton embodying the improvements of my invention, with portions of the structure broken awayto show the liner.

Figure 2 is a similar construction.

Figure 3 is a perspective other modification of the invention; and

Figure 4 is a similar view showing the cover p n. I a

Figure 5 is a perspective view of still another modification having a tear strip removable to provide a pouring opening.

In terms of broad inclusion, the invention comprises a wall of weakness to form a tear strip. In one form of the invention the tear strip enclircles the carton to separate it into cover and body sections. A

, liner in the carton provides a sleeve with which carton of my view illustrating an- Y tioned to fit snugly within the carton and is held by frictional engagement with the walls.

Means are provided for conveniently opening the" carton. For this purpose I provide spaced rows of perforation 8 defining parallel lines of weakness and preferably extending transversely across all four walls of the carton body to prohaving spaced lines the cover section engages for reclosing the con-- I tainer. In another form of the invention the" Pull strip 0 vide a tear strip- 9 encircling the carton. .T.he tear strip is preferably disposed about the upper portions of the carton to divide it into a main section and a cover section I: of less height than the main section. It is understood that tear strip 9 lies only in the outer walls of the carton, leaving liner 6 extending the full length of the carton whenthe tear strip is removed. The cover section l2 may then be slipped oil over the flanges formed by the projecting end of the liner and replaced at will, providing a reclosable carton of neat appearance and affording a tight seal when the cover section is replaced. .Since there is morefrictional resistance between the liner and main carton section than between liner and cover, due to the shorter height of the latter, the liner is not displaced when removed.

Means are also arranged to'provide a finger hold on thepull strip. To this end I preferably make two parallel cuts l3 aligned with perforations 8. and join these cuts with a perpendicular cut l4, making an H-shaped pair of tabs I;

is thus provided at each end. enabling a person to tear out the strip from either'end. is a'decided advanthe cover is incision to form a This incision is shown located in a side wall, but it may be formed in an-end wall, or partly in one'wall' and partly in another" 'to arrange the tabs atfan edge otthecarfon;

completely torn out; Tabs I6 normally lie in the plane of the carton wall and are not apt to be dislodged during ordinary handling, yet may readily be lifted out by inserting a'iingemail or pointed instrument between the tabs. One tab bends back as the other is lifted out to facilitate grasping the outturned tab. The carton above described is particularly wel adapted for packaging breakfast cereals and other products used from time to time so that the reclosable feature comes into play. Such products may be packed directly within the carton or within a bag disposed in the carton.

Figure 2 shows a modified construction in which the tubular liner is omitted and the tear strip 9 located closer to the top of the carton. .In

this form the top is to be thrown away when the carton is opened. The contents may either be packed directly within the carton or within a bag I1.

Figures 3 and 4 disclose another modificati'on wherein the tear strip 9 extends across only three walls of the carton, preferably across the side walls and one end wall, leaving the other end wall intact to form a'hinged connection for the cover section. The tear strip maybe formed as a horizontal band, or may have inclined portions along the side walls terminating at upper corners as shown. A cut l8 across each end of the strip terminates the tear-out. In the construction tag'e should the strip accidentally tear crosswise when pulling from one end before the strip is inwardly or pulled outwardly to form a relatively large pouring opening, which opening decreases in size when the wall springs back into its normal plane. e

I claim:

A carton having spaced lines of weakness in walls thereof to provide a tear strip for effecting separation of the carton into main and cover sections upon removal of the strip, said tear strip extending across three of the walls of the carton in spaced relation to the top wall of the cover section to leave main and cover sections connected by the fourth wall on a line closely adjacent two of the adjacent corners of the fourth wall, and a still tubular open ended liner in the carton coextensive with the side and end walls thereof to provide a flange over which the separated cover section may be reseated in its unopened position to leave exposed a band of the liner equal in width to thetear strip.
