Claims. (Cl. 229-9) This invention relates to cartons of paper material and more particularly to a carton having a slide intended to be opened from one end to properly expose the contents.

In the packaging of articles such as cigarettes and the like it is desirable to provide a carton or box of paper material including a sleeve open at both ends, with a slide being arranged to be received within the sleeve in the closed position of the cart-on, and to be pressed partially out of the sleeve in the open position, to expose the contents of the box. The slide incorporates side and end Walls as well as overlying flaps at the top and bottom in order properly to retain the contents. One of the flaps, that at the top end, is preferably cut into the bottom wall to make it more flexible and thus it is desirable that the slide be moved in the proper direction to expose the top rather than the bottom flap. This facilitates access to the contents when the slide is opened in the proper way, but makes it awkward and difiicult to remove the contents if the slide should be projected from the sleeve in the opposite direction.

It is accordingly the principal object of the present invention to provide a box or carton of paper material suitable for the packaging of cigarettes or the like in which the slide is arranged to be received in a sleeve and so constructed that it can be opened readily by advancing or projecting the slide in only one direction, i. e., the direction which will properly expose and permit ready access to the contents of the carton.

It is a further object to provide such a carton in which the slide has an end flap at one end which is wider than the width of the sleeve in which the slide is mounted such that the end flap overlaps the sleeve and tends to resist projections of the slide except in the proper direction.

It is also an object to provide a carton of this type in which the side walls of the slide are formed by partial cut and score lines so arranged that insertion into the sleeve is facilitated, the slide is frictionally retained in closed position, and the flap on the slide is allowed to seat in position without creating excessive friction thereon.

It is a further object to provide such a carton in which the top flap is also wider than the width of the sleeve and in the closed position of the slide is frictionally engaged internally to yieldingly hold the slide in closed position within the sleeve.

It is a still further object to provide a carton in which the bottom of the slide is tapered such as to tend to prevent removal thereof in the wrong direction and to facilitate insertion of the slide into the sleeve while filling and assembling the carton.

Other objects and advantages will be apparent from the following description, the accompanying drawing and the appended claims.

Fig. 17 is a transverse sectional view through the slide inserted in the sleeve, the section being taken through the top flap.

Referring to the drawings which disclose a preferred embodiment of the invention, a blank 10 is shown for forming the slide. It comprises a central bottom panel 11 having a bottom fold line 12 and an upper or top fold line 13 parallel thereto with two opposite fold lines 14, 15 which are not parallel but which taper toward each other. The amount of taper may vary and has been somewhat exaggerated in the drawing in order bet ter to illustrate the construction, but it will be understood that the width of the bottom panel at its upper end in Fig. 2 is appreciably greater than the width at the bottom end.

An upper end flap 16 is integrally formed at the upper end of bottom panel 11, being flexibly related thereto along fold line 17 with the diagonal cut or perforated lines 18 providing for greater ease of access to the contents when the carton is in open posiiton. Where perforations are used they retain the portion 2% of the bot tom in the same plane as the main part of the bottom until the package is opened the first time. Also as will be evident from the drawing the width of end flap 16 is somewhat greater than the adjacent width of the bottom panel 11.

Integrally joined to end flap 16 is a top extension flap 22 which is slightly narrower in width than flap 16 but of a width preferably not less than the width of adjacent bottom panel 11 and arranged to fold with respect thereto along fold line 23. The corners at the ends of fold line 23 are notched out as shown at 24.

At its lower end the bottom panel 11 has integral end flap 25 and extension flap 26 foldable thereon along fold line 27. The flap 26 is preferably of less width than the adjacent Width of panel 25. Inner side wall panels 30 are arranged to fold along lines 14, 15 and outer side wall panels 32 are connected by means of score lines 33, 34 at each end and by a central cut line 35 to form a double wall side construction for the slide, suitable adhesive 36 being applied to retain the side walls in this folded over condition. End tabs 37 are adapted to be folded within end flap 25 when the sides and ends are erected, and may be secured thereto by application of adhesive or left free as desired. The score line pattern of the tabs is shown in Fig. 2.

The sleeve is shown generally at 40 comprising top panel 41, side panels 42 and bottom panel 43, all integrally joined and separated by fold lines 44 with an extra overlapping flap 45 carrying adhesive 46 which is adapted to be secured to the flap 42, forming a simple sleeve construction of uniform cross-section.

When the sleeve is so assembled, its internal width between its side walls is substantially greater than the width of the bottom portion of panel 11 but less than the top thereof. The result is that the slide can be readily inserted into the sleeve with its narrow end foremost, and can likewise be readily projected out of the sleeve in the opposite direction. Fig. shows the slide in position about to be introduced into the sleeve and it will be apparent that the lower extension flap 26, by reason of being slightly narrower than the space between side walls 32 (Fig. 7), is allowed to drop inwardly slightly below the level of the side walls (Fig. 10), which thereby facilitates insertion of the slide into the sleeve. As the slide travels into the sleeve friction between the slide and the sleeve increases proportionally until the slide has been fully inserted at which point the internal Width of the sleeve at the top is substantially equal to or slightly in excess of the distance between the sidewall panels of the slide at the top and thus there is a tendency frictionally to retain the slide within the sleeve. The inwardly folding top extension flap 22 is allowed to rest on the shoulders formed by score lines 33 of the side wall panels (Figs. 7 and 10) and this tends to provide further frictional engagement at this point between the slide and the sleeve, since the overall thickness of the slide is increased by the overlaying fiap 22, thereby fitting tightly into the sleeve atthe upper end.

As the carton is closed, the Wider portion of the slide is received within the sleeve and a gradually increasing frictional resistance is developed as the slide approaches its innermost position, shown in Fig. 1]. By pressing the slide upwardly from the bottom relative to the sleeve, the contents are readily accessible and by lifting the top flap 22 the perforations 18 are broken and free access is provided to the interior.

The width of the top extension flap 22, while not as great as top end flap 16, is at least equal to the external space between opposite side walls 32 and hence as shown in Fig. 12 the outer edges 56 of flap 22 are squeezed and turned slightlydownwardly as the slide is pressed to its innermost position, being rolled over the scored portions 33 of the side walls. As shown in Fig. 7, the bevel 51 on the top flap is such that it preferably clears the cut area 35 of the side walls but leaves a projecting portion over the areas 33 to accomplish this frictional and squeezing engagement as described immediately above.

The slide may be readily opened by applying pressure to the bottom end causing the slide to be projected outwardly in the direction toward its wide end. The slide is not adapted for removal in the opposite direction because as will be evident from Fig. 13, the tapering side wall construction 36, 32 will wedge into the sleeve and tend to bind, thereby indicating to the user that the slide should be moved in the opposite direction. Further, since the top end flap i6 is of a width at least equal to the width of the sleeve, it forms a projecting portion 55 at either side which lies on top of the adjacent edges of the sleeve, and this portion 55 will thus engage or abut the sleeve and serve to resist or prevent such undesired removal in the wrong direction, and further indicate to the user that the slide should be opened by pressing in the opposite direction.

Referring to the modified construction shown in Figs. 14 through 17,:a similar construction isshown to that already-described, and correspondingparts carry the same reference numerals. In this form, however, an additional top panel is employed which is of a shape generally corresponding to bottom panel 11, with a recessed portion 61 at its upper edge to facilitate access to the contents of the package. There is also the flap portion 62 carrying adhesive 63 by means of which the lower end of the package can be firmly secured in assembled position, as distinguished from the freely open construction of the previous form. The construction in this respect is shown in Fig. 16. In addition, side wall panel 65 is provided which overlaps the opposite side panel 66, the latter likewise carrying adhesive, and thus further stiffening the assembled slide construction. It will be further noted that end tabs 37a are relatively short and are intended to be folded inwardly at the bottom of the package, thereby completely closing the lower end thereof.

Reference to Fig. 17 will show that the double thickness provided by the overlapping of flaps 65 and 66 of the slide is located at one side of the carton with the double thickness provided by the overlapping walls 42 and 45 of the slide located on the opposite side of the package. The construction .thus provides a firm and essentially strong arrangement throughout since it has triple thickness at each side, a double thickness at the bottom and likewise a double thickness of material on the front and back faces.

While the package is shown as containing cigarettes, and as employing a sheet 68 of metal foil or the like, it will be obvious that such protective packaging may be used as desired, and further that other articles may be packaged, the device furnishing a convenient construction for many articles having a somewhat similar shape.

The whole construction therefore is simple and inexpensive in manufacture, and provides a device which assures the opening of the package in the proper direction. When opened the contents are fully and readily available and when closed, the slide is yieldably held in closed position until access is again desired. If the user presses the slide in the proper direction it opens freely and readily, and thus assures that the package will be manipulated in the manner intended.

While the articles herein described constitute pref-erred embodiments of the invention, it is to be understood that the invention is not limited to these precise articles, and that changes may be made therein without departing from the scope of the invention which is defined in the appended claims.
