1:. claims." (ci. 22a-1s) This invention relates to hing-ed cover containers, and more particularly to a paperboard container comprising a box part and a cover part lto .terescope over thehinged thereto and adapted open end of the box part.

In accordance with this invention. the improved containermay be formed from a single vto a securing ilap connected to one of the side Wall panels of the box part, which side wall panel and its associated securing flap is then folded to overlie the previously folded pull-up flap, and finally the front wall panel is folded so as to overlie the otheradjacent sidewall panel and the glued face of the securing ap.

blank of paperboard material comprising Va box l forming part having a cover forming part hinged thereto along a transversely extending'score line. The box forming part comprises front, rearand side wall panelsarranged in side by side relationf ship and adapted to be secured together in tubu- In erecting. the assembled container, the merchanise packerfdraws the pull-up flap farther into the tubular body of the box part, which operation causes the body portion to expand into tubular form and simultaneously draws the botlar form. `A bottom wall panel hinged to the lower end of the rear wall panel ,carries a pull-i connected to the adjacent lower ends of the side wall panels by bellows fold sections which serve to seal the ends of the bottom wall panel to the adjacent lower ends ofthe side wall panels when the box part is erected.

The cover part comprises a top Wall panel hinged to the upper edge of the rear wall panel of the box part,.a front flange section hinged t the top wall panel, and side wall sections hinged to each end of the front flange section. Each side wall section is provided with a securing tab adapted to be. arranged to overlie the inside face of the top wall panel. An abutment ilapis secured to the inside face of the front flange section which is adapted to cooperate with the abutment flap associated with the front wall panel of the box part to retain the cover part, when assembled, in closed position.

The container forming blank is so shaped and designed as to permit assembly thereof in co1- lapsed condition so thata large number of col lapsed assembled blanks may be stacked together in a small cubical space for shipment to the merchandise manufacturer. tion can be speedily performed at a high produc-f tion'rate on an automatic strip gluing and folding machine which operates to apply vadhesive 'to the abutment flap associated with the -cover part The' assembly opera-A tom wall panel into end sealingl position. The abutment flap associated with the pull-up.tab is then folded Aover the notched upper edge ofthe front Wall panel of the box part so as to overlie the outside face thereof. Amerchandise plug may then be inserted into the assembed box part.

The cover part is assembled by folding the securing tabs and the side wall sections at right angles to the front flange section and then :fold-I ing the front flange section at right angles to the top wall panel of the cover part. The cover part can then be swung into closed position, and when the cover is closed it will retain its assembled form. An adhesive tape or strip may Athen be applied over the top wall panel and side wall sections of the cover part so as to retain these parts in permanent assembled form. Y

. This improved hinged cover container is so constructed as to permit shipment to the user in collapsed assembled form and yet permit erection and final assembly of the complete container by a few simple folding operations and without requiring the application of glue or adhesive theeto. The container is adapted for the' packaging of numerous' articles of merchandise and when assembled is sturdy and strong in construction and attractive in appearance.

An object of this invention is to provide an im` 1- proved hinged cover container adapted to be sol formed from ia single blank of paperboard material which can be assembled in collapsed form at high production speeds and at low cost for shipment to the merchandise manufacturer, who may then readily erect the container by a few simple operations which can be performed by hand or automatically. A Another object ofthis invention is to .provide an improved hinged cover containerv having a cover part which may be assembled without adhesive and which thereafter may be held together in iixed assembled form by the application of a sticker tape applied thereto.

Another obJect of this invention is to provide an improved paperboard blank from which a hinged lcover container may be quickly formed and assembled.

Other objects of this invention will become apparent as the disclosure proceeds.

Although the novel features which are believed to be characteristic of this invention will be particularly pointed out in the claims appended hereto, Vthe invention itself, as to its objects and advantages and the manner in which itmay be carried out, may -be better understood by referring to the following description taken in connection with the accompanying drawings torming a part thereof, in which:

The blank as shown in Fig. l may be cut from large sheets or rolls of paperboard material which have preferably ilrst been lithographed or printed. The paperboard sheets or rolls may be cut and scored on an automatic cutting and scor- 1 ing machine at a high yproduction rate so as to produce individual blanks in the form illustrated in Fig. 1.

'I'he blank as shown in Fig. 1 comprises a box forming part a and acover forming part b which are hingedly connected along the transversely extending score line 2l. The body portion of the box is formed from a front wall panel `I, a rear wall panel 2,. and side wall panels 8 and 4. One side edge of the iront wall panel I is connected by a longitudinally extending score line 6 to the adjacentside edge of the `side wall panel 3 while the opposite side edge of side wall panel 3 isv connected by av longitudinally extending score line 9' to the adJacent side edge of rear wall panel 2. The opposite side edge of rear wall panel 2 is connected by a longitudinallyextending score line 9" to the adjacentside edge of side wall showing the bottom wall panel in end closing position, certain parts being broken away to illua.

A bottom vlforming panel 1 is connected by a transversely extending score line 9 to the lower end oi' the rear `wall panel 2. A bellows fold corner section 9 is connected by a transversely bil extending score line 9 to the lower end of the side wall panel I and is connected to the ad-v jacent end of the bottom forming panel 1 by score line 9 which is substantially a continuation of score line 9 which joins side wall panel 9 to the rear wall panel 2. A similar bellows fold section 9 is connected by transversely extending score line 9' to the lower end of side wall panel 4 and to the adjacent end of bottom forming panel 'I by score line 9" which is substantially a continuation of score line 9" which connects rear wall panel 2 to side wall panel l. Each of the bellows fold sections 9 is traversed by a diagonal score line I0 which divides the bellows fold section into a fold portion 9' and a fold portion 9", as illustrated in Fig. 1.

A pull-up flap I2 is connected by a transversely extending score line I3 to the bottom forming panel 1 which, when the container is assembled is designed to be arranged adjacent the inside face of front wall panel I. The transverse score line I3 extends substantially parallel to the score line 9 and deiines the bottom wall panel 1 therebetween. A locking ap I4 is connected'to the pull-upilap I2 by transversely extending score line I5. Each side edge of the pull-up flap I2 is notched as si; I9 at a point adjacent the score line I6 so as to provide the locking flap Il with end extensions I4'. Each side .edge of the pullup ap I2 is notched as "at I9 adjacent the score line I9 to permit the bellows fold sections 9 to fold inwardly into container assembling position in the manner hereinafter described.

'I'he cover part b comprises a top wall panel 29 hinged to the upper end of rear wall panel 2.

along the transversely extending score line 2| and a front flange section 22 hinged to the top wall panel 23 along a transverse score line 23 which extends -substantially'parallel with the score line 2|. A fixed abutment flap 2l'is connected by transverselyl extending score line 2l to the front flange section 22, the score line 23 extending substantially parallel to the score `line 23.

Each side wall of the cover part is formed by a side wall section 23 hinged to each/end of the extending score line 21. The free outer edge of each side wall section 23 may possess a curvilinear' contour 2B to enhance the appearance of the side wall section. A fold-in tab 23 is connected by a transversely extending score line 33 to each of the side wall sections 23. Each told-in tab 29 is separated from the adjacent end of the top wall panel 2II by a longitudinally extending cut 3| and is separated from the adjacent lfront flange section 22 along a longitudinally factbry for `shipment tothe merchandise manufacturer and stored-until ready for. use. The i i -assembled collapsed blanks thus require miniin the expanded tubular bodyof the box part.

is pulled upwardly in the direction of the arrow end of the side wall panel of the box part by a l transversely extending cut 32. Each-of the score lines 33 may extend substantially in alignment 40, as shown in Figs. 7 and 8. The upper end of the pull-up flap I2 is readily accessible through the open upper end oi the box part. The upward pull exerted on the pull-up nap I2 causes the bottom forming panel 1 to swing into end closing position. Simultaneously each of the bellows fold sections ,3 collapses or folds about the diagonal fold line liiso as to position the belwith score line 23. One of the score-lines 21 It will be noted by referring to Fig. 1 that the upper transverse edge 36 of the front panel I of the box part is placed below and out of alignment with the transversel score line 2I. Each end of the transverse edge 36 joins a beveled edge 31 which extends to the top shoulder edge 38 of the front wall panel I. The depressed transverse edge 36 provides a seat for the folded locking i'lap I4 associated with the pull-up ap I2 of the box part, as will be more particularly described hereinafter.

The blank I is glued and (folded into the collamed assembled form illustrated in` Figs. 4 and 5 by a few simple high speed operations which can be perfumed on an automatic folding and gluing machine. This assembly operation is ac-` complished by iirst applying a, strip of adhesive g to the inside face -of the abutment nap 2l, as shown in Fig. 1, following which the abutment flap 24 is folded over and adhesively secured to the inside face of the xfront'ange section 22, as illustrated in Fig. 2. Substantially simultaneously with this folding operation, the pull-up flap I2 at the bottomend of the blank is folded about the transverse score line I3 so as to overlie the inside face of the bottom panel 1 and the rear wall panel 2, in the manner illustrated in'Fig. 2. A strip of adhesive is then applied to the outside yface of the securing flap 5, following which the side wall panel' 4 is folded about score line 6" so as to overlie the infolded pull-up flap I2, as illustrated in Fig. 3. The front wall panell is then folded about score line 6 so as to over- A `so as to produce the assembled collapsed blank as illustrated in Fig. 4.V The assembledl collapsed blanks, each formed as illustrated in Fig. 4, may

lows fold portion 3 in position to overlie the inside face of the bottom wallpanel 1 and place the complementarybellows fold portion 3' in position to overlie its assoclatedbellows-fold portion 3". Each of the bellows fold sections 3 is free to fold in the manner indicated and without obstruction or interference fromthe pull-up .tab I2 by reason of the notches I3 provided in the adjacent edges of the pull-up nap I2. Each of the notches I9 is shaped so as to clear the bellows fold sections 3 as they undergo collapsed folding, as illustrated ln Fig. 17.

When the pull-up flap |2 has been drawn to its full upward position, it will be noted by referring to Fig. 9 that the bottom wall panel 1 is in position to fully close the bottom endof the box part a and that the bellofws foldpcrtion 9" of each bellows fold section 3 snugly overlies the inside face of the bottom wall flap 1 with the complementary bellows fold portion 9 snugly overlying its associated bellows fold portion 3". It will be further noted by referring to Fig. 9 that whenthe bottom wall panel 1 is .in proper end closing position, the transverse score line I5 at the upper end of the pull-up flap I2 will be substantially in alignment with the depressed top permit the locking flap Il to be drawn forwardly so as to overhang the outside face of the frontv wall panel I of the box part, as illustrated in Fig'. 10. The end extensions Il' of the locking ap I l are suiliciently resilient to readily flex over the tapered edges 31 of the front wall panel I as the looking vldap is folded over thedepressed edge 36 of the front wall panel, and will then flex back to their original extended position so that the locking ilapll and its associated end extensions I4 may lie flat against the outside face of` front wallpanell. a y

The locking iiap Il will remain in its downturned locked position shown in Fig.u 11 with the end extensions I4' constantly abutting the shoulder portions 31 of the upper side edges of the front wall panel I. lThe. locking flap I4, however. can be swung from its downturned position to a position approximately at right angles tothe l front wall panel I without releasing or unlocking the end extensions I4' y from their position of abutment against the shoulder portions 31 ofthe be stacked together `and packaged at the box front wall panel I. .lhe lower tree-edile I9 of the abutment lisp Il is so designed and proportioned as to abut the infolded free edge 24' of the vfixed abutment nap 29 associated with the e cover part when the cover part is bled in closed position.y The locking ap'I also serves to maintain the bottom wall panel 1 in fixed end closing position so that'the end wall panel I has into the assembled box part, 4as illustrated in Fig.

11. 'I'he cover part is then assembled, as illustrated in Fig. l1, by folding the cover tabs 29 associated side wall sections 2-9, by folding side wall sections 29 at right angles to i'ront ilange section 22 and by folding the lfront danse section 22 at right angles to the top wallpanel 29. as illustrated in Fig. l1. vIf desired. a spot of adhesive a may be applied either to the outside face of each of the tabs 29 or the inside face of the top wall panel 29 at each end thereof. so that when the tabs 29 are positioned so as to overlie the inside .face of the top wall panel 29. the tabs 29 will be rmly'secured thereto.- However. the operation of lgluing the tabs 29 to the inside face of the top wall panel 2li may; if de sired, be eliminated and the side wall sections 29 may be held in tlxed assembled positionv by the use o! a piece of sticker tape 99, as illustrated in Figs. 13. 16 and 18 and hereinafter described.

When the cover part b has been assembled in the form shown in Fig. 1l, it may then be telescoped over the cover part into the closed position illustrated in Fig. 12. When the cover part ls in closed position, the front flange section 22 overlies the front wall panel I and the side sections 29 of the cover part overlie the adjacent side wall panels 9 and 4 of the box part. It will be further noted by referring to Fig. l5 that the abutment edge .24 of the fixed abutment flap 24 will be positioned so as to abut the lower free edge I9 of the hinged locking flap Id. The xed abutment4 flap 24 serves both as a means for retaining the bottom wall panel 1 in closed position and as a means cooperating with the abutment flap in the cover part to retain the cover in closed position and resist opening thereof.

It will be noted that when the cover part is in the closed position illustrated in Figs. 12 and 15,

the cover part is maintained in xed assembled position even thoughf-the tabs 29 of the cover part are not adhesively secured to the top wall panel 29. If, however, the cover part is opened the side wall sections 29 of the cover part will tend to swing outwardly, as illustrated in Fig. il,

and disarrange the proper assembled position of the cover. If, however, an adhesive sealing strip 59 is applied overl the top wall panel 29 to extend over the side wall sections 29 and into engagement with the side wall panels 9 and I, the cover part will there-by be maintained in fixed assembled position even though the adhesive strip is broken along lines as shown in Fis. 16 and the cover partv swung open as shown yin Fig. 19. Thus it will be appreciatedA that the operation .required in adhesively securing the tabs 29 to the tcp wall panelv 29 may be eliminated if, after the cover part is in closed, position as shown in Fig. 12.-a sealing -strip 99 is adhesively secured to the top wall panel 29 and the side wall sections. 29 of the cover part. The sealing strip into position substantially at right angles to their assess:

`I9 maybeintheiorm ofsrevenuestampor the sealing strip may comprise any other strip oirpaper which may be suitably imprinted or decorated. `The sealing strip 69 provides'a seal for the cover part which must be broken or mutilated before the cover part can be opened. The sealing strip 99 may be provided with a series of transverse pertorations 9| to tix the tear point ot the sealing strip at or adiacent to the lower edge of the side wall section 9. Thus the sealing strip99 is held intact at points between side wall sections 29 and the top wall panel 2 9 of the cover part so as to maintain the sections 29 and the panel 29 in iixed assembled position.

When access to the contents is desired, the

'sealing strip is broken along the perforated lilies` 9| and upward`pressure exerted on the lower free edge of the front flange section 22 of the cover part. Stresses are thus imposed upon the front wall panel and rear wall panel 2 of the box part, causing them to bow as illustrated in Fig.I 17. The stresses thus engendered resist opening of the cover part` and maintain the cover part in positive closed position until suillcient upward force is exerted on the front flange section 22 to overcome itsresistance. However, a very light' downward force only need be exerted on the top wall panel 29 of the cover part to ei'i'ect closing of the cover part. The hinged abutment flap Il and fixed abutment flap 24 are so shaped and proportioned as to offer the desired resistance to the normal opening or closing of the cover part, so that the cover part is Vretained in closed position and will not open during normal handling of the container. Thus the cover part can only be opened by applying force to the cover part sumcient to overcome the resistance offered by the hinged abutment ilap Il and the fixed abutment nap 29. The swinging movement of the hinged abutment flap Il to the extent necessary to open and close the cover will not release the end extensions I4' of the flap I4 from their abutting position against the outside face of the shoulder portions 99 of the front walliJanel I.

The blank shown in Fig. l may be cut and formed at high speed on an automatic cutting and scoring machine and -the blank can be assembled into the collapsed assembled form shown in Fig. 4 on an automatic strip gluingv and folding machine at a high production rate. The merchandise manufacturer can quickly assemble the boxpart of the container by the simple operation of exerting an upward pull on the pullup nap I2 and bending the locking flap I4 into position so as to overlie the front wall panel I. The merchandise plug or package can then be readily inserted into the open end of the box part. The cover part. as shown in Fig. 18. may be quickly assembled by folding the tabs 29, the side wall sections 29 and the 'front ange section 22 at right arrgles to one another, following which the cover part may be swung into closed position as illustrated in Fig. 12. When the revenue stamp or sealing strip 99 is adhesively applied to the cover part, as shown in Fig. 13, the cover part will at all times be maintained in its proper ilxed assembled position. The cover part and box part arev so constructed that the cover part will not open during normal handling of the'container.

The improved container above described is strong and sturdy in construction and attractive in appearance. The container is adapted for the packaging of numerous articles vof merchandise. such as smoking tobacco, cigars, cigarettes and other articles of merchandise which` have heretofore been packaged in metal or-other rigid hinged cover containers. This improved merchandise container can be manufactured, packed and assembled at substantially less than the cost of rigid containers of comparable equally as serviceable in use.
