The telescopic dispensing folding box illustrated in Figs. 1 through 10 comprises the outer box'section generally indicated 1' and the inner box section 2. The configuration in common of the inner and outer box sections may be as desired; as illustrated in Figs. 1 through 8, their common configuration is rectangular, having their opposing

side wall panels

3, 4 and l4, l narrow and the other opposing

side wall panels

5,6 and l6, l1 broad.

The outer section I is of approximately the same height as the inner section 2, and comprehends substantially the entire body of the latter when the container is in retracted position. The outer box section is hollow-formed from the blank shown in Fig. 9, while the inner section 2 is hollow-formed from the blank shown in Fig. 10.

The blank or the outer section, as shown in Fig. 9, comprises the

narrow panel walls

3, 4, the

broad panel walls

5, 6, and a conventional glue .lap 1, all disposed in side-by-side serial alignment, as illustrated. Closure panel 8 extends from the upper end of the broad panel 6 and is provided with a tuck flap 9; closure-supporting flaps in, II, respectively, extend from the upper ends of the narrow panels 3, 4'.

In the upper portion of the narrow panel 3 is an area 24 defined by vertical cuts 24a and horizontal lines of perforation 24b to provide a tear ou portion, the purpose of which appears more fully hereinafter.

From the lower end of the

narrow panels

3, 4 of the blank'or the outer section, extend limitstop tabs l2, 13.

The outer section I of the container is formed from the blank of Fig. 9 in conventional manner by first folding and gluing the same into a collapsed tubular shell which then may be expanded to rectangular hollow status.

The blank or the inner section 2. shown in Fig. 10, comprises the narrow panels l4, ll, thebroad panels 16, I1, and the glue lap lBa disposed in side-by-side serial alignment. Extending from the lower end of the broad panel i6 is the bottom closure panel l3 and its tuck flap I9.- The closure supportin

flaps

20, 2|, extend respectively from the lower ends of the narrow panels l4, l5. As shown in Fig. 10, extending from the upper ends of the narrow panels l4, iii, are

limitstop tabs

22, 23, respectively, which are adapted to co-operate-as appears more fully hereafterwith the limit-stop tabs I2, I3 01 the outer section i.

The innersection2 is formed from the blank of Fig. 10, also pursuant to conventional pro. cedure, as in the case of the outer section I.

The dimensioning of the respective panels of both the outer and inner sections and the setting up and assembly thereof, are carried out with particular regard for close interfitting so as to gain the objectives of precision fit, relatively high rigidity of the sections when assembled, nicety of telescopic relationship thereof during the stages of their relative extension and retraction, and

. assurance of limitation of maximum extension of the sections effected by cooperation of the limit stop tabs.

The above qualities are well illustrated in Figs. 1 through 6.

Viewing in particular Figs. 5, 6- and '7, it will be observed that the inner section 2 is closely dimensioned with respect to the outer section I in their transverse peripheral relationship; that the

limit stop tabs

22,23 or the inner section, though unglued or otherwise secured, are held definitely in position in close physical contact with the outer faces, respectively, of the narrow panels l4 and iii of the inner section and with the inner faces respectively of the

narrow panels

3 and 4 of the outer section. Likewise the limit stop tabs l2, [3 of the outer section, though unglued or otherwise secured, are held definitely in position in close physical contact with the inner faces respectively of the

narrow panels

3, 4 of the outer section and with the outer faces respectively of the narrow panels I4, iii of the inner section. Upon telescopically extending the inner section 2 with respect to the outer section Icompare Fig. 7 with Fig. 6 and Fig. 3 with Fig. 2the stated

limit stop tabs

22, 23 of the inner section engage, at their free ends, in edge-to-edge abutment with the free ends of the limit stop tabs l2, 13 of the outer section and thereby definitely limit the extent of outward telescopic movement.

The relative positions of the outer section I and inner section 2 of the box, in the fully extended condition illustrated in Figs; 3, 6 and 7,

are important as respects the placement of the tear-out portion 24, which gives rise to the dispensing opening 25, in preferably one of the narrow wall panels of the outer section I, here specifi-' cally shown in the narrow wall panel 3. These relative positions should be such that the top edge of thecorresponding narrow wall panel i5 0! the inner section is substantially flush with the lower defining edge of the dispensing opening 25. In order to obtain these desired respective positions of the outer section I and inner section 2 relative to each other when the box is fully extended, the combined lengths of those limit-- stop tabs which comprise anyone of the two 'Fig. 9, it will be 25. Stated somewhat differently, there should be Just sufficient space between the abutment edges-of the respective coacting limit-stop tabs of a pair of same when the box is fully retracted to allow extension of the box only so far as will place the top edge of the narrow wall panel I! of the inner section in alignment with the lower defining edge of the dispensing opening 25.

The exact lengths of the respective .coacting limit-stop tabs of each pair of same will, in great measure. depend upon the size of the dispensing opening 25. The size of the dispensing opening will depend, of course, upon the use for which the box is designed, and may vary considerably in individual instances. 1

Fig. 2 illustrates the tear out" portion removed, thus giving rise to the dispensing opening 26 located in the narrow panel 3.

It will be observed that prior to the stage when such "tear-out" portion 26 is removed, such weakened--but unremovedportion 2t serves to seal the dispensing opening until the stage is reached when the user desires to dispense contents from the box.

The blankof the outer box section shown in Fig. 9 and the blank shown in Fig. represent to true scale these parts of commercially produced embodiments of the invention. It will be observed from Figs. 9 and 10 that the panels 8, i, b and t of the inner box section are or true rectangular configuration; likewise, the panels ltl, id and it, and the major portion of the panel ll, of the inner box section, are of true rectangular configuration.

Furthermore, upon forming the outer and inner box sections as above described, including the folding of thelimit stop tab 22 of the inner box section upon itsjassociated panel it, and telescopically assembling th inner box section within the outer box section, it will be observed that the limit stop tab is brought into juxtaposition with the inner face of the panel 3 and its dispensing opening 26, assuming the tear-out" portion 25 to have been removed as directed. 'll qhe assembly thus attained is represented in By reference to Fig. 10 and in comparison with observed that the length of the limit stop tab 22 is greater than the distance from the upper margin of the panel 8 (at which the closure-supporting flap it is hinged) to the lower edge Nb of the dispensing opening 25. This distance as measured from the stated com parison of Figs. 10 and 9 is increased by the thickness of the material of the blank of the inner box section, shown in Fig. 10. Such relatively greater length of the limit stop tab 22 is of importance in that the free edge of the limit stop tab 22, when thus folded in the thus assem bled container, is located below the stated lower edge 26b of the dispensing opening, thereby insuring absence of interference between the limit stop tab 22 and the lower edge Mb or other part of the material of the outer box section defining the edges of the dispensing opening 25. In summary, the stop limit tab 22 is dimensioned to locate its edges without the zone of the edges defining such dispensing opening, and thus preclude physical interference of its edges with the edges of the dispensing opening.

of the inner box section Fig. 4 indicates a manner of dispensing'the contents from the extended box, the contents being illustrated in the form or one or more pel-; lets extended, the inner container 2 may bear the legend Pull, see 21, Figs. 1 and 2, and the contiguous central edge portion of the

broad panels

8, 8 of the outer container I may be arcuately indentured to reveal such indication and to provide a finger grip for facilitating such telescopic extension.

For the purpose 01' "looking" the closure panel 6 of the outer section I in position together with its tuck flap 9, slits 30, 3| are cut at the opposite extreme terminations of the score line 32 at the margin of the cover panel and it tuck flap '9. For similar purposes slits 3t, at, are cut at the opposite extreme terminations of the score line 85 at the margin of the cover panel i8 and its tuck flap it of the inner section 2, as appears in Fig. 10.

The embodiment shown in Figs. 11, 12 and 13 28. For indicating how the box should be comprises the structural and functional features comprehended in the embodiment shown in Figs. 1 through 10. Parts of the embodiment of Figs. 10, 11 and 12 corresponding to those of the embodiment of Figs. 1 through 10, are designated by like reference characters.

The embodiment of Figs. 11, 12 and 13 presents the further structuralfeature of the limit-stop tabs which belong to the inner section, blanked and formed within the general contour of the wall-forming panel of the blank, that is to say,

. they do not extend outwardly to effect an irregular contour of the blank as in the preceding embodiment, thus affording considerable saving in paper stock. These limit-stop tabs of the inner section of the present embodiment are designated 36, embodiment is shown formed of a blank which duplicates the blank illustrated in Fig. 9.

The blank 01 the inner section 2 is shown in Fig, 13. Perforated score lines 38, 39, formed within the wall panel i6, define the lower edges of the limit-

stop tabs

36, 37 respectively. By such arrangement the limit-stop tabs 86, 37, are held flat and protected against damage from the stage of production of the blanks to the stage of their assembly within the resulting container, thus preserving the strength and peripheral contour of the limit-

stop tabs

36, 37. To assemble the blank of the inner section 2, the cut scores 38, 39 are "broken to afford folding of the limit-stop tabs into their functional positions.

Desirably, the wall panels ii and 6 of the outer section are arcuately or otherwise indentured, see 27, Fig. 11, to provide clearance for grasping the inner section, thereby facilitating telescopic extension of the two box sections relative to each other. The wall panel i6 of the inner section, from which the limit-

stop tabs

36 and 31 are cut, is preferably provided with an extension, see 62, Figs. 11 and 12, to insure against inadvertent opening of the container when'the box sections are extended.

In the embodiment of Figs. 11, 12 and 13, the

slits

33, 36, cut at the extremities of the score line 35, have each an inner arcuate termination, the score line at extending between such arcuate terminations and thereby being positioned inwardly of the blank relative to the major portions of the slits 33, 8t.

Another embodiment is shown in Figs. 14 through 21, wherein the outer section is designated it and the inner s ction 46. a

31, respectively. The outer section i of this The outer box section 45 is holloweiormed from the blank Fig. 17, while the inner box section 48 is hollow-formed from the blank of Fig, 18.

The blank 0! Fig. 1'1 comprises the broad wall panels 41 and 41, respectively, the

narrow wall panels

48 and 48, respectively, and a conventional glue lap 48, all disposed in integral sideby-side serial alignment, as illustrated. Closure flaps 58 and 58 extend from the upper ends of the broad panels 41 and 41, respectively, and a closure-supporting flap 5| extends from the upper end of one of the narrow wall panels 48 for forming a conventional glued-type top closure for the outer box section 48. The upp r portion of the other narrow wall panel 48 is cut laterally and is divided from the remainder of the panel by a score line, indicated 82, for providing an upper lateral closure section 48a. Extending from the upper end of such panel section 480 is a flap 58 which corresponds to the closure-supporting flap 5| and normally has the same function, but which forms a part of the lateral closure provided in part by the panel section 48a. From the lower ends of

narrow wall panels

48 and 48 extend limit-stop tabs 54 and 84, respectively, preferably, as in the prior embodiments, of widths less than the widths of the wall panels from which they extend. The lower edges of the broad wall panels 41, 41, may be arcuately indentured substantially' centrally thereof as at 55, 55, respectively, to provide a finger grip for facilitatingtelescopic extension of the outer box section 45 relative to theinner box section 48.

The outer box section 45 is hollow-formed from the blank of Fig. 17, while the inner box section 48 is hollow-formed from the blank of Fig. 18.

The blank of Fig. 17 comprises the broad wall panels 41 and 41, respectively, the

narrow wall panels

48 and 48, respectively, and a. conventional glue lap 48, all disposed in integral sideby-side serial alignment, as illustrated. Closure flaps 58 and 58 extend from the upper ends of the broad panels 41 and 41, respectively, and a closure-supporting flap 5| extends from the upper end of one of the narrow wall panels 48 for forming a conventional glued-type top closure for the outer box section 48. The upper portion of the other narrow wall panel 48 is cut laterally and is divided from the remainder of the panel by a score line, indicated 52, for providing an upper lateral closure section 48a. Extending from the upper end of such panel section 480 is a flap 53 which corresponds to the-closure-supporting flap 5| and normally has the same function, but which forms a part of the lateral closure provided in part by the panel section 48a. From the lower ends or

narrow wall panels

48 and 48 extend limit-

stop tabs

54 and 54, respectively, preferably, as in the prior embodiments, of widths less than the widths of the wall panels from which they extend. The lower edges of the broad wall panels 41, 41 may be arcuately indentured substantially centrally thereor as at 55, 55, respectively, to provide a finger grip for facilitating telescopic extension of the outer box section 45 relative to the inner box section 48.

The outer box section 45 is formed from the blank of Fig. 17 in conventional manner by folding and gluing the same. The flap 58, it should be noted, is allowed to remain unsecured under the top closure 58, so that it, together with the panel section 48a, may be pulled out from the completed box to form a pouring discharge aperture 51, see Figs. 15, 16 and 19. The limit-

stop tabs

54, 54 are folded against the inner face of I the blank, and are preferably glued in place as illustrated in Fig. 20.

The blank of Fig. 18 comprises the broad wall ing from the lower ends of broad wall panels 80 and 88 are bottom closure flaps 83 and 88, respectively, and extending from the lower ends of narrow wall panel 8| and 8| are bottom closuresupporting flaps 84 and 84, respectively, such closure and closure-supporting flaps forming a conventional glued-type bottom closure. Formed by suitable sets of cut lines provided at corresponding locations intermediate the lengths of narrow wall panels 8| and 8| are limit-stop tabs 29 85 and 85, respectively, adapted to fold outwardly and downwardly on the transverse score lines 88 and 88, respectively, see Fig. 21.

The inner box section 48 is formed from the blank of Fig. 18 in substantially the same manner as the outer box section 45 is formed from the blank of Fig. 17, the bottom closure flaps and closure-supporting flaps being adapted for folding and glueing to form the sealed bottom closure 81, see Figs. 15, 16, and 19. The outwardly and downwardly folded limit-stop tabs 85, 85, may be left free, as illustrated in Fig. 21, but may, if found desirable in particular instances, be secured, as by gluing, to their corresponding narrow wall panels 8|, 8|, respectiveiy.

In assembling the box, the inner box section 48 is slid, with its open top end going first, into the outer box section 45 through the open bottom end thereof. The limit-stop tabs 85,- 85 of the inner box section 48 slide over the limit-stop. tabs 84, 54 of the outer box section and snap against the inside faces of the

narrow panel walls

48, 48, respectively, thereof with an outwardly-urged pressure fit. Thereby, the inner box section is 45 locked within the outer box section for limited telescopic movement relative thereto.

.After gluing of the respective closure and c osure-supporting flaps to form the top closure 58 and the bottom closure 81, telescopic exten- 50 sion of the two box sections relative to each other, within the limit set by the locations of the limit-stop tabs 85, 65, uncovers the pouring discharge aperture 51 from the inside, and opening of the lateral closure, comprised of the panels 56 48a and 53, as previously described, permits discharge of contents from the box, see Fig. 16. Telescopic retraction of the two box parts relative to each other to an extent such that the top of the inner box part abuts against the sealed 0 top closure 58 of the outer box part, effects closure of the pouring discharge aperture 51 from the inside, and, therefore,

53 may, if desired, be torn off and discarded.

The same advantageous factors permitting ac- 85 curately aligned gluing of the individual box sections and facility of collapse of the telescopically assembled box from set-up condition to flat shipping and storing condition apply here as in the previously described embodiments. In

7 attaining the latter advantage, it is desirable that both the bottom and top closures of the box be glued after the telescopic assembly of the I I two individual sections, relative to each other,

is completed.

The characteristics of true rectangular conthe lateral closure 48a,

figuration of the panels of the outer and inner box sections and the resulting transverse cross sectional formations of true rectangular configuration of the inner and outer box sections, and also the relationship of the length of the concerned respective limit stop tabs with regard to the edge or edges defining the dispensing opening, apply with respect to the embodiment shown in Figs. 14 through 21 and follow the charac-' teristics herelnabove described with reference to the respective embodiments shown in Figs. 1 through and Figs. 11 through 13.

It should be noted that the present embodi-.

ment provides for a rather short telescopic stroke of the two box sections relative to eachother in forming the desired discharge opening, 1. e.. the pouring discharge aperture 51. Because of this feature, the limit-stop tabs 66, 85 are cut out and provided at an intermediate location along the lengths of the narrow panel walls 6i, ill of the blank of Fig. 18, rather than being provided by tabs extending from the ends of such narrow panel walls, which tabs would have to be of considerable length to effect the short telescopic stroke here desired, and, thus, would greatly increase the size of the blank of Fig. 18.

As appear from the foregoing the invention generically and with respect to the illustrated three perferred embodiments thereof, provides a container comprising a plurality of telescopically related box sections, each box section hollowformed from foldable material to provide two oppositely related narrow lateral walls, the box sections being arranged for telescopic movement 1 relative to one another and having telescopically close sliding fit. the container being provided with a dispensing opening which when the box sections I are in fullyretracted relation is closed by a .wall of the box sections serving as a closure, which closure is removed to render the dispensing opening operative within a range of predetermined telescopic extension of the box sections, combined with limit-stop means associated with the narrow side walls of the box sections and arranged to mutually co-act in abutting relationship for limiting the degree of telescopic extension of the box sections within such predetermined section, the inner section having a fixedly closed ally related sections having uniform configuration in transverse cross-section throughout their respective lengths and having close sliding fit to ensure edge-to-edge abutment of said sets of tabs to provide limit stops when said s. ctions are in extended position, an outer of said secti ons being provided with a dispensing opening disposed in one of its walls and located to be opened when said respective sets of tabs are in edge-to-edge abutment and closed when said sections are in retracted telescoped relation.

range, to aiiord dispensing of the contents of the container.

The various embodiments of the invention aforedescribed each comprises only two sections. Additional middle sections, substantially similarly formed but with open ends, may be provided for cooperation with the closure-provided sections, if desired, for increasing the capacity of the box in well-known telescopic manner.

Whereas this invention has beenillustrated an described with respect to several specific embodiments thereof, it should be understood that various changes may be made in such specific embodiments and numerous other embodiments may be constructed by those skilled in the art without departing from the spirit and generic purview of the invention as set forth herein and in the claims here following.
