Similar reference characters refer to similar parts throughout the several views of the drawings and the speciiication.

In accordance with this invention, the container-'itself is formed from a single blank of suitable material which has been so cut and scored as to permit assembly thereof on standard available boX assembling machines. The dispensing slide may also be formed from a single blank of suitable material which may be assembled in slide form by a simple and quickly executed assembly operation and then inserted into position to form an operating part of the fully assembled dispensing container.

In one form of the invention the container itself is assembled from the blank A as shown in Fig. l, which is substantially rectangular in outline and may be cut and scored from large sheets or rolls of material on an automatic cutting and scoring Ymachine at a high production rate. If desired, only one side of the material need be finished and imprinted, whichside, when the blank is assembled, forms the outside surfaces Vof the container.

The blank as shown in Fig. 1 comprises a panel I, which for convenience in description may be called the rear wall panel, which is hinged to a betteln wall panel. :2r along a transversely extends ina ere .li-ne 4...

Bottom tabs IB and I Il'- are hingedlyconnected.y to each end of the bottom Wall panel 2 alongparallel extending score lines II and II' which are arranged slightly out of alignment with the score lines 'I and l respectively to permit as.- sembly of the blank into container form. A top wall forming flap I2 is hinged tothe upper end of the rear wall panel I alonga transversely extending score line 2|. Info-lcling tabs I3 and I3 are hinged to the opposite ends ofthe outer top Wall forming flap I2 along parallel extending score lines Ill and le respectively. The score lines I4 and Ill are slightly out of alignment with the score lines 'I andA 'l' respectively to permit folding assembly of the folding tabs I3 and I3.

A sealing flap I5 is hinged to the outer top Wall forming panel I2 along a transversely extending score line I6 which extends substantially parallel to the score line 2ll The infolding tabs I3- and I3 are separated from the adjacent side Wall forming naps 6 and 6 respectively by cuts ZI which extend substantially in alignment with'the score line 2|. The inner top Wall panel I1 is provided with a securing iiap I9 hinged thereto along a score line 2l) which extends substantially parallel to the score line I8. The securing ap I9 is adhesively secured to the inside face ofthe rear Wall panel I adjacent the upper end thereof, as will be hereinafter more fully brought out.

A suitable dispensing opening 22 is provided in the outer top Wall panel I2 which, when the oo ntainer is assembled, aligns with the dispensing opening 23 provided in the inner top Wall panel IT. The dispensing opening 23 maybe formed by ,a line of perforations 24 which permit removal of the circumscri-lced disc as desired to provide the opening. A slit 25 is provided in the outer tOD Wall panel l2 which extends transversely ber-- tween score lines 2l and I 6. The slit -25`provides an opening through Which the dispensing slide may extend so as to overlie and depress porftion I2 of the outer top Wall panel and underlie and bulge upwardly or outwardly portion I2" of the outer top Wall panel I2.

rlhe blank A shown in Fig. 1 may be quickly assembled into collapsed shell form at the box factory by running the sarne through an automatic strip gluing and folding machine.M Such machine operates to apply a strip of adhesive to the outside face of securing ilapv ISY as the lola-nk` passes through the machine and then operates to fold the inner top, wall panel Il about 'score line I8 so as to overlie the inside face of the front wall panel 3. As the blank continues to advance through the machine the rear wall panel I is folded about score line 4 so as to overlie the-inside face of bottom Wall panel -2 and front -Wall panel 3V, bringing the upper end of the rear wall panel I into adhesive Contact with the securing tab I9.

The inner top wall panel I'I is secured? to rea-r wall panel I by the securing iiap lil, While the outer top Wall panel is secured to the'frontwajll. panel f3 by the sealing flap I5.

The partiallyassembled shell thus expandedV is r11-n. through. an end sealing machine which, as shown in Fig. y'7, .operates to fold the paired in.- foldi-ng tabs IIJ and I3 inwardly to close .one open side of the box. Side Wall forming ilap 8 is then folded so as to overlie the inturned tabs I0 and i3; adhesive is applied to the inside face ofthe other companion side wall folding flap which -is thereupon folded over and pressed into adhesive engagement with the outside face of the inturned side Wall formi-ng flap 8, as illustrated in Fig. 8.

With one side Wall thus closed, the partially assembled; container may be inverted into the posit-ion shown in Fig, 9, so as to rest on its closed side,r whereupon the contents may readily be inserted through the other open side thereof.

Ell-.elaleph l. infinies the dispensing slide may be out and scored yfrom large sheets or rolls of suitable material on an automatic cutting and scor The blanlg B; as shown in Fig. 2 comprises a cody section 353` hai/ing a finger grip section 3l lhinged-to the body section Si] along a transversely extending scoreline .32. A foot sectionV 33 is hinged to the` other end of the body section 30 along a transverse score line 34. The. foot section 33 is designed to be folded under one side of the body section 39. A dispensing opening 31 is provided which straddles the score line 34. The disp-ensing opening 3'! may, if desired, be circular in form. When the foot section 33 has been folded under the body section 30 the dispensing opening appears as a notch in one end of the body section. Foot portion 33 is provided with a notched cut-out 35 and abutment edges 36. Sift holes 38 may be provided in the body section 30 and a small notch 39 may be provided at each end of the score line 34 to facilitate insertion of the slide B between the top wall panels of the container as will later appear.

The blank B shown in Fig. 2 may be assembled into dispensing slide form by merely folding the foot section 33 so as to overlie the inside face of the body section 33. The notch 35 in the foot section leaves the dispensing holes 38 in the body section 30 fully exposed and unobstructed.

As shown in Fig. 12, the dispensing slide is inserted through the slit 25 provided in the outer top wall panel I2. Insertion is effected by depressing portion I'2' of panel I2 and outwardly bulging portion I2" of panel I2 to permit insertion of the foot section and of the slide through the slit 25. The slide is pushed into position until the entire body section 3E! is positioned between portion I2" of the outer top wall panel I2 and the inner top wall panel Il. When thus positioned the linger grip section 3| will overlie the depressed portion I2' of the outer top wall panel I2 permitting convenient manipulation of the slide B for opening and closing the aligned dispensing apertures 22 and 23.

When the dispensing slide B is in fully closed position the unperforated portion of the body section 3B will lie between the aligned openings 22 and 23, as illustrated in Figs. 13, 14 and 15, so as to effectively seal these openings and prevent any loss of the contents. ln the event it is desired to remove the contents by sifting, the finger grip section 3l is grasped and the dispensing slide pulled so as to bring the sift openings 38 into alignment with the dispensing openings 22 and 23. If bulk dispensing of the contents is desired, the dispensing slide is further moved so as to bring the dispensing opening 3l in the end of the body section 35 into alignment with the aligned openings 22 and 23, permitting bulk dispensing of the contents as illustrated in Fig. 17. It will be noted that when the slide is in the bulk dispensing position as shown in Fig. 1'?, the slide cannot be further withdrawn since the edges 36 of the foot section will abut the depressed edge of portion I2 of outer top wall panel I2. If due to denting or excessive pressure on the outer top Wall panel I2 the top panel is forced inwardly, the foot section 33 of the closure member may slide under the end portion I2 of the top panel, thus providing an additional safeguard against an accidental removal of the closure slide B from between the top panels I2 and Il. The dispensing slide may be returned to closed position by exerting a pushing force on the finger grip section 3| so as to push the body section 39 into the closed position in which it will lie fully. within the confines of the top Wall panel I2.

By cutting and scoring the container blanks in the form shown in Fig. 18, a highly satisfactory dispensing container may be formed therefrom by the use of standard box Vassembling machines of somewhat different kind than used to form the container shown in Fig. 1. The blank A as shown in Fig. 18 need be *finishedV or imprinted on oneside thereof only, and may be cut and scored at a high production rate on an automatic cutting and scoring machine. The blank comprises a panel 4I, which may be termed the front wall panel, which is hingedly connected to a bottom wall panel 42 along a horizontally extending score line 44. An opposite or what may be called a rear wall panel 43 is hingedly connected to the bottom wall panel 42 along a horizontally extending score line 45 extending substantially parallel to the score line 44. Side Wall forming flaps 45 and 46 are hinged to the opposite side edges of the front wall panel 4| along parallel extending score lines 47 and 41 respectively. Side naps 48 and 48 are likewise hinged to the opposite side edges of the rear wall panel 43 along parallel extending score lines 49 and 49 respectively. Side tabs 50 and 53 are hinged to the opposite ends of bottom wall panel 42 along parallel extending score lines 5I and 5I' respectively. Score lines 49 and 49 are substantially in alignment with score lines 41 and 4lV respectively, and score lines 5I and 5I are slightly out of alignment with the respective score lines 41 and 48', to permit folding assembly of these tabs.

An outer top wall panel 52 is hinged to the upper end of the front wall panel 4| along a horizontally extending score line 6I. A tuck-in tab 53 is hinged to the upper end of the side wall ap 46 along horizontally extending score line 6I" While a similar tuck-in tab 53 is hingedly connected along transversely extending score line EI to the upper end of side wall flap 45. Score lines 5I are slightly out of alignment with score lines EI to permit infolding of the tabs 53 and 53. Tabs 53 and 53 are separated from the end of outer top wall panel 52 by cuts 54 and 54 respectively. An inner top wall panel 51 is hingedly connected to the upper end of the rear wall panel 43 along a horizontally extending score line 58. A sealing flap 55 is hingedly connected to the outer top wall panel 52 along horizontally extending score line 53 which extends parallel to score line 6I The outer top wall panel 52 is provided with a dispensing opening 62 which is arranged to align with a dispensing opening 63 in the inner top wall panel 5l when the container is assembled. The outer top wall panel 52 is also provided with a slit 65 extending between the score lines 58 and 6I. The dispensing slide, assembled from the blank B shown in Fig. 19, is adapted to be inserted in position through the slit 35 when the container is assembled. Each of the top tabs 53 and 53 is provided with a cut-out 62 at the free ends thereof, which cut-outs are arranged to align with the dispensing opening 62 when the tabs 53 and 53 areY in inturned container assembled position. It will also be notedthat the bottom tabs 5I! and 5B' are separated from the lower ends of the side Wall forming aps 46 and 45 respectively by limited notched cut-outs 59 and 59. The opposite side edge of the bottom tabs 58 and 58' are cut on a bevel at x so as to intert and abut the beveled lower end of the adjacent side wall flaps 48 and 48' respectively.

The blank A shown in Figure 18 is assembled into container form by applying adhesive to the inside facesrof the side wall flaps 46 and 45. The machine on which this blank is assembled is provided with a plunger which seats on the bottom Wall panel 42. Elements associated with the machine operate to raise the bottom tabs 53 and 59 at right angles to the bottom wall panel 42, raises the back Wall panel 43 at right angles to the bottom Wall panel 42, swings-the side wall flaps 48 andd into alignmentwith the bottom tabs 59 and 50 respectively, raises the'front wall panel 41 into positoinV substantially at right angles vto the bottom Wall panel 42, as shown in Fig. 21, and then folds the side wall flaps 46 and .43 into overlyin-g adhesive engagement With .side nap 48 and bottom tab 58 and side flap 48 and bottom tab 59 respectively. At the conclusion of this as.- sembly operation 'the container will be partially assembled in the form shown in Fig. 22.

The container shown in Fig. 22 is then ready to be filled with contents. After .lling the container is run through an end sealing -machine which operates to fold the top tabs 53 rand53 in.- wardly into alignment as sho-Wn in Fig. 23, With the cut-outs 62 together forming la dispensing opening. The inner top Wall vpanel 51 .is tloen folded to overlie the inturned tabs 53 and '53', outer top wall panel 52 is folded to overlie the inner top Wall -panel 51, adhesive is applied to the inside faceof the sealing nap 55 and, nally, the sealing flap 55 is folded over and pressed into adhesive engagement with theloutside surface of the rear Wall panel 43. The container as thus assembled, filled and sealed appears as shown in Fig. 25.

The dispensing slide for'the container shown in Fig. 25 may be formed from blank B shown in Fig. 19. The blank B comprises a body section 1i having a finger section 12 hinged tothe body section 1l along a transversely 'extending score line 13. A Wing section 'id is hinged to each side edge of the body section 1| along'score li-nes 15. The free end of the body section 1i Ymay be provided with a dispensing cut-out "i5, YWhile the body section 1l may also be provided Withfa series of -sift openings 11 in advance of the dispensing cut-outl 16.

The blank B shown in Fig 19 Vis assembled rinto a vdispensing slide, by folding and, if so desired, adhesively 4securing the wing sections I4 to the body section '1 i. It will vbe noted by referring to Fig. 26 that the Wing sections 14 When infolded and secured to the body section 'il do not cover or obstruct the vsift openings 11. The ends 18 of the -wing sections 14 provide abutment edges which prevent removal ofthe dispensing slide when the dispensing slide has been inserted into operative position through the slit 5 of thecontainer. Insertion of the dispensing slide is aecomplished by depressing portion 52 of the outer top wall panel 52, inserting the appropriate end of .the slide through the slit 65, and pushing the slide until substantially the entire body portion 1l thereof is positioned'between portion 52" of the outer top wall panel 52 and the inner top Wall panel 51, as illustrated in Figs. 27 and 28. When thus positioned, the siide Will close the aligned dispensing openings 52, 93 Aand '62 so that the contents cannot escape. If it is desired to sift out the contents, the nger grip section 12 is grasped and a pull exerted on the slide until the siftopening-s l1 therein align with the aligned dispensing opening-s 52 63, 62.` If b-ulk dispensing of the contents is desired, the .dispensing slide is further Withdrawn, as lshown in Fig, 30, untilthe dispensing cut-out 15 aligns Withfthe aligned dispensing openings 62, .6.3 and 52. 'Further withdrawal of 'the dispensing slide is prevented since .the .ends 1.8 of the Wing sections 14 will then abut the depressed edge portion 52" of the outer top wall panel 52.

By .cutting and scoring the .container blank in the Iform shown. in Fig. 31a highly satisfactory 110 dispensing container may be formed therefrom by the use of standard stripgluing, folding and endsealing'machinery. The blank A" as shown in Fig. 81 need be finished for imprinted -on one side only and may be cut andrscored at a yhigh production rate on an automatic cutting and scoring machine.

The blankis show-n with its inside surface facing thevobserver and comprises a panel A8.0, which will be termed a-front wall panel for convenience of description. The front Wall panel has side Wall panels '8l andf82 hingcdly connected thereto along vvertically extending score lines 83 and 84. An opposite panel 85, vwhich for convenience may be called a ,rear Wall panel, ishi-ngedly connected to the side wall panel 8l along a vertically -eX- tendingscore L"li-ne 86. .An end flap-81 is `vhingedly connected vto itheside wail panel v82 along a verticaliy veat',.ending score 'line y138.

Blank A, shown in Fig. 31, may quickly be assembled into .collapsed shell -or `sleeve for-m at the box factory by'running the blank through an automatic strip gluing and folding machine. Such machine operates to apply a strip of adhesive tothe outside face of the Aend flap 81 as the lblank vpasses through the machine and then operates to fold the side panel 82 about the score line 84 so as to overlie the inside surface of the front wall 'panel 80, as shown in Fig. 32. As the blank .continues to advance through the machine, the Arear Wall vpanel 85, together with the bottom and inner top wall 4panels -93 and 91 connected to the side edges thereof, is folded about the score line 186 so as `to overlie the inside face of the -side Wall panel j8| bringing `the rear Wall panel into adhesive contact with the sealing iiap 81. Pressure applied, as by a suitable pressure roller, V'presses the sealing ap `81 into rm ad- 11 hesive engagement with the inside facej of the rear wall panel 85 adjacent its outer edge.

Thus prepared, the blank forms a collapsed shell or sleeve structure as shown in Fig. 33, which is discharged from the machine ready for stacking and shipping to the plant Where it may be expanded and filled as needed., Y

The merchandise manufacturer can continue and complete the assembly of the collapsed shell quickly and expeditiously on standard box assembling equipment. For this purpose the assembled shell or sleeve structure is first eX- panded into tubular form as shown in Fig. 34. The partially assembled shell is run through an end sealing machine Which, as shown in Figs. 34 to 37,.closes the top end wall consisting of the supporting tabs 94 and 95, the inner top wall panel 91 and the outer top wall panel |99.

In the initial stage the machine operates to fold the paired supporting tabs 94 and 95 inwardly to close the open top side of the container. The inner and outer top wall panels 91 and |99 are then folded outwardly about the score line 96 and adhesive is applied to the inside face of the inner top Wall panel 91 and the sealing nap as shown in Fig. 35. As the container progresses through the machine the inner top wall panel 91 is pressed into rm adhesive engagement with the supporting tabs 94 and 95, as shown in Fig. 36. Thereafter the outer top wall panel |00 is folded over so as to overlie the inner top Wall panel 91 and the sealing fiap |0| is pressed into rm adhesive engagement with the top portion of rear wall panel 85 adjacent its top score line 9B. Thus assembled the container has the form shown in Fig. 37 and is ready for lling with merchandise.

For the purpose of lling and final sealing the container is either placed on its side or top, depending upon the type of end sealing machine used.

For the purpose of illustration it will be assumed that a top end sealer is used, requiring inversion of the prepared container so as to rest it on its top wall structure, as illustrated in Fig. 38. Merchandise, which may either be loose or in the form of contents enclosed in a bag |06, is inserted into the container through the open bottom aps 89 and 90 and bottom panels 92 and 93. The package may or may not have adhesive g applied to one end thereof so as to become adhesively secured tothe inside of l the supporting flaps 94 and 95, if thisv is desired.

After insertion of the contents the filled container, passes through the end sealing machine, which in its rst operation folds the bottom naps 89 and 9U inwardly to close the bottom and folds the bottom panels 92 and 93 outwardly, as shown in Fig. 39. Adhesive is applied to the inside surfaces of the bottom panels 92 and-93 and the panels are then folded inwardly in succession to close the container, as shown in Fig.' 40.

After sealing of the bottom, the container may be set upright as shown in Fig. 41 and a closure member B may be inserted through the slit. Obviously, the closure member may be of any suitable form, such as illustrated, for example, in Figs. 2 and 19. The closure member includes a finger operable tab portion 3|, a main body portion 39, and an abutment portion 33 folded underneath the body portion 30 about a score line 34. The closure member after insertion into the completed and lled container may be moved into three distinct positions. In the first posi- `tion the cut-outportion 31 registers with the dispensing apertures 98 and I U3 for bulk dispensing, in the second position the fist openingsSS register with dispensing apertures 98 and |93 for sift dispensing, and in the third position the imperio-rate portion of the closure member closes the dispensing apertures 98 and |93 completely.

After reaching the consumer the container is opened by first moving the closure member B into its open position, in which the knock-out 98 is removed and the package |96 punctured underneath the dispensing opening if the Contents are enclosed in such a package.

Manifestly the sliding closure member may be inserted before filling of the container with merchandise, i. e., at the stage of assembly of the container shown in Fig. 37.

It is now seen that I have provided a convenient dispensing container which is neat and attractive in appearance, and which may be easily manipulated either to sift dispense or bulk dispense the contents therefrom. The container itself is formed from a single blank of paperboard or other suitable material which is so shaped and formed as to permit assembly thereof on high speed automatic box assembly machines of standard design. The blanks are so shaped and cut as to be substantially rectangular in outline and result in little waste of material, The blanks need to be imprinted or finished on one side thereof only since only one face of a blank is presented as the exposed face of the assembled container. The dispensing slide may likewise be formed of a single piece of suitable material and may be assembled by a simple gluing and folding operation. The slide is so formed as to permit insertion through the slit provided in the outer top Wall panel of the container after the container itself has been fully assembled and filled with the contents. Once the slide has been inserted into position it cannot be withdrawn but yet can be easily manipulated either to close off the dispensing opening, to present sift openings for dispensing purposes, or present a larger opening for bulk discharge of the contents.

The blank unassembled or partially assembled in collapsed shell form at the box plant, permits packing for shipping and storage purposes within a minimum of space, thereby effecting decided economies as compared with the shipment and storage of rigid set-up containers. The merchandise manufacturer may conveniently and economically assemble or complete the assembly of the container on standard box assembly equipment, which is substantially automatic and requires no highly skilled labor for its operation. rThe improved dispensing containers may be advantageously employed for the packaging of powdered or granular materials which have heretofore been packaged in cans or canisters wholly or partly formed from sheet material, or other more costly material.
