Referring more particularly to the features of invention embodied in the modifications shown by the various figures of the drawings, designates a cosmetic powder container of cylindrical configuration, with 2 indicating the lateral walls thereof. The cover of the container, not shown, may be of the type which is provided with downwardly extending flanges, similar to lateral walls, and is adapted to telescope over walls 2 in a close fit, the free edge of the flanges or walls of the cover seating on flange 3 of the container. Package seal 4 is permanently attached to lateral walls 2 of the container in any expedient manner, as by resort to an adhesive applied to pleated portion 5 of the seal, whereby the said seal in effect comprises an upper wall of the container. Any decorative or ornamental covering 6, usually paper, may then be superimposed over said portion 5, and afiixed thereto as well as to lateral walls 2 in any desired fashion, as by an appropriate adhesive composition.
The dispensing funnel or spout of Figs. l-6 is shown as an integral part of package seal 4, being made from the same unitary blank. Referring to Fig. 7, the blank generally designated as 5, is stamped or cut from a sheet, fragmentarily shown, of any flexible or foldable material, desirably paper of predetermined characteristic and texture. Fold or crease line 9 determines the top surface iii of the package seal 4.
An opening |3 is determined in the seal by flaps I i, which are adapted for folding along crease or score lines IS. The segment 11, which includes the generally triangular portion projecting beyond the circular part of blank 5 shown in Fig. '7, is foldable relative to projecting portion l8 along crease line l9, and this projecting portion is in turn foldable along crease line 23.
Segment I1 is further provided with two additional rectangular shaped projections 2| and 22, extending from opposite apices at side 23 of the segment. Projection 2| is foldable relative to segment I? along crease line 24, while projection 22 is foldable with respect to segment i! along crease line 25. Projection 2| is further supplied with a fold line 26 as well as a slit 21, the purport of which will be apparent from the description hereinbelow.
In forming the dispensing funnel 1, projection i8 is folded over on crease line 2!] so as to be superimposed on portion 28 of the blank, fold line I9 then substantially coinciding with fold line 9, or crease line 32 representing the pertinent portion of said fold line 9. While projection l8 may be adhesively attached to portion 28 of the blank, this expedient is not esssential since in the ultimate positioning of seal 4 on the container, as shown in Fig. 3, the ornamental material 6 will be superimposed over the correlated association of H3, 23 and will retain them in position against lateral walls 2 of the container. It will be noted that the surface area of projection I8 is such as to correspond essentially with the surface area of blank portion 28.
At this stage, segment H is pivotable along score or crease line i9 at the edge 9 of the package seal and, therefore, adjacent opening l3 of the seal. Portions 29 of segment foldable along crease lines 35), are affixed to flaps M of opening l3 by adhesive or the like. In this connection, the dimension of line 3| on each side of projection |8 desirably corresponds with the length of the flaps l4, corresponding with fold line I6. Accordingly the attachment of the flaps 14 to the respective portions 29 of segment these parts being appropriately faced and aligned relative to each other with lines 3| coinciding with fold lines I 6, results in projections 2| and 22 being free at this stage of the dispenser construction. Folding projection 2| along line 24 to a position at right angles to flap l4, and thus into a position to span the edge 32 of opening I3, portion 35 forms a wall or guard means relative to opening l3 and opposite to that determined by segment 21, which is that portion of l! bordered by line l9 and lines 30.
' The edges 33, 34 of projection 2| are of essentially the same dimension as edge 32 of opening |3, and crease line 26 will, therefore, coincide with edge 32 under these conditions. Portion 36 of projection 2| is attached to the top H] of seal 7 4 by any expedient adhesive material, with crease ase ne tin here whent e iunnelisi l e n o s u t m e shape f r u e... conve in urface. n s asu q tantial y t ian ularcon s r r n or e d wi hjwal 1. ateralwalls' 38, f. he, ip n f nn l. matte f lde along their. respective creaselilles 315 M and, 31"; .10

The manner of foldingthe dispenser. of Fig, 3y
along its. respective ,crease linesnmay. desirably follow the procedure. described hereunder inthe detailed consideration presented relative tothe functioning of the dispenser. shown in Fig; B and... it is therefore discussed only generally at.,..this-- point.

The device 0f-Fig;.;4 is generallysimilar to-that of Fig. 3 with respect'to its fundamental struc-.-- ture and functioning characteristics. However it represents a modification of the funnel orspout shown in Fig. 3 to the extent that the-crease': lines on the respective'walls: are -reversed;,with the result that-the funnel .of-Fig. .4 folds in precisely the opposite direction tothatof the' funnel shown in Fig. 3. Thuscrease.lines'corres-ponding to! L l 2, 31, 31a, shown on lateral wall-38 of Fig.3, are
to that indicatedv in Figs,,l-7, and in its completedform,.-.it is shown by. the. perspective. of. Fig. 8.. The fragmentary, disclosure.. of the, seal..surface.: is designated'as .42. and.theppeningthereinris 4.3
Referring to the ,funneL'or dispenserin its. open position as shown in Fig. 8, 44 designates the rear wall, while the side walls are indicated as 45, 45'. The rear wall 44 determines the conveying surface in this modification, and the guard wall is designated 45. This dispenser is attached to the seal 42, shown in fragmentary proportion, by causing flanges 4i, 4|, 5!, 5| to adhere to the undersurface of the seal.
Lateral wall 45 is subject to being folded along transverse crease line 48'. Side wall 45 is provided with transverse fold lines 48, 48a, thesebeing in effect coextensive when the wall is extended after in the position shown in Fig. 8. Accordingly and as pointed out above in the description relating to Fig. 3, the crease lines on the respective lateral walls 45 and 45' are not symmetrical, since they difler as to their number andmanner of functioning. In addition, wall 45 is shown to have fold or crease lines 45a, 40, these lines being essentially a continuation of each other and embracing the longitudinal dimension of this lateral wall substantially from its apex portion 49 to guard wall 45; however, as will be noted from the drawing, fold line 45 is angularly disposed relative to fold line 40a and the angular association may approximate that of a right angle or a somewhat obtuse angle when the wall is in an extended position as in Fig. 8, but there is no intent to be restricted to any particular angle, since this may be subject to variation without deviating from the purport of the invention. The juncture of lines 40' and 44a is desirably on the transverse crease line 48, 48a.
Guard wall 46 may be foldable to a substantially triangular form by folding two areas 72 along their respective crease lines 41, 41'. Thus the area '12 determined by lines 69, H and 41 is foldable along line 41 by forcing this area to a position adjacent the inner surface of wall 46, at which time vertical edge 69 of wall 45 essentially coincides with line i I contiguous the seal opening, and horizontal edge I l of wall 46 assumes a position substantially at right angles to said line H. Similarly the other area (2, determined by lines l8, l2, and 4'! is foldable to overlie the inner surface of wall 45, with edge falling along line ll and edge 72' becoming vertically positioned with respect to said line ll. With both areas 12 folded in as described, edges 59 and 19 of wall 46 form a substantially coextensive straight line along line i I, while edge portions 1 l T2 of wall 46 desirably overlap somewhat and define a line vertically disposed relative to the line determined by edges 59, 10.
In the ultimate folding of wall 45, the longitudinal area P on one side of crease lines 40a, 40 is to be folded over corresponding area Q on the other side of crease lines 40a, 40. Thus in this overlapping of area P on Q, crease line 48a assumes an angular position relative to crease line 48; the extent of this angle is subject to variation, dependent on the degree of overlapping of area P over area Q and may desirably be an acute angle. It is not essential that P completely overlaps Q, but it is quite desirable that some overlapping be afforded throughout the length of the lateral wall, as along fold line 40a, 40'.
To collapse the dispenser, walls 45, 45 and 45 in effect simultaneously alter their relative status. As lateral wall 45 becomes overlapped on itself by folding area P over area Q along lines 40a, 40', with crease line 48a assuming an angular relationship relative to crease line 48, lateral wall 45' is in effect simultaneously folded over wall 45, crease line 48' thereby essentially overlying crease line 48a. It will also be noted that the collapsing of the dispenser results in wall 45 being substantially folded over on itself, and wall 45' is likewise essentially doubled over, but the folding of these respective walls is attainable through the above indicated different fold lines. The ultimate effect is the interposing of wall 45' within the folded wall 45, but the contact between the respective walls is on their reverse or inner surfaces.
At the same time guard wall 45 becomes folded by the moving in of areas 12 as previously described. At this stage, lateral walls 45' and 45 are longitudinally overlapped, with the latter being folded over itself and with guard wall 46 assuming a substantially triangular form, although it may still be in a practically vertical position relative to the seal surface. This longitudinal overlapping of the lateral walls 45, 45 at this point results in the upper portion of the overlapped walls being in a comparatively vertical position relative to the lower portion of the overlapped walls which are in a comparatively horizontal position. To collapse the dispenser to a horizontal position and into essentially the same plane as that of the seal, the overlapped lateral walls 45, 45' are doubled over along the now essentially superimposed fold lines 48, 48a, with the edge of the seal opening at the base of rear wall 44 serving as a pivot line. Similarly guard 45, in its substantially triangular form, is foldable to a horizontal position in superimposed relationship to the lower overlapped, substantially horizontal portion of lateral walls 45, 45', the line of juncture between guard 45 and the seal opening providing the axis for this pivoting. The overlapped apex portion 49 is desirably caused to overlie folded guard wall 46, in its horizontal position with the apex being adapted for insertion through slit 52 of seal surface 42 to be pocketed between portion 50 of flange 5| and the under surface of the seal.
This pocket structure is attainable as a result of the manner of attachment of flange 5! to the under surface of seal '42. Referring to Fig. 8 it will be seen that portion 5!! is an integral part of flange 5! intermediate the edges of said flange. While the surface of the flange is provided with an adhesive or bonded material or the like 55 for attaching the same to the under-side of the seal, intermediate portion 53 is free from any bonding or adhesive material. The dimension of portion 50, as will be apparent from the showing in Figs. 8 and 9, is such as to embrace the slit 52 as well as the length of apex 49, which is intended to protrude through the slit 52 when the funnel is attached to the seal and closed or collapsed relative thereto. Alternatively a collar may be superimposed on and attached to the dispenser flanges. The collar may then be caused to adhere either to the outer surface or to the under surface of seal 42 in coordinated association with the seal opening. If desired an independent slit for the apex portion of the dispenser may be provided by the attachment of a strip of material to the seal surface, and this expedient is applicable to any of the modifications shown. Conversely where a pocket type of slit is contemplated for the dispenser apex, an appropriate area 55, free from adhesive, is allowed on the side of the collar which is adhesively attached to either the outer or under surface of the seal to render the dispenser integral with the seal and to provide a pocket for the dispenser apex. In the latter construction, it will be understood that adhesive or bonded material is similarly omitted from that portion of the flange 5 Fig.4 1 1 eliminate corners 64,65 and resulting in the apex -19 5I.and .theoverlying collar,portiontoprovide the appropriate Ilpocket .-for receiving the dispenser apex.

Thus except for the tip ofcollar' I3,the under surface of collar I'3 may be adhesiv'ely or-in any other expedient manner attached to the-surface of seal'53 in perimetric relationshipto'seal' openin 55, said seal opening being coincident with dispenser opening 55'. As -for-' this tip portion extending from slit I5, atleast in sufiicient extent to provide a, pocket for funnel apex 66, it is free-from attachment to the seal surface. 7 V
However,- it 3 will be clear that, it is not necessary* to have ,the dispenser inlet correspond in dimension with 1 the seal opening, since the device willbe equally-operative despite avariation in thecorresponding Sizesof the ,seal opening and said inlet. "Generally. any such discrepancy maybe compensated by the dimension of the collarjI3. Forqexamplewhere the inlet end of. the dispenser is smaller than theseal openring,'the collar may be designedto. overlap the seal opening and thereby allowior theprevailing difference.
Illustrative of the attachment of. dispenser. E8 to the seal, it maybe superimposed over opening 55,.with,the flanges .58 and BiLas wellas any free portionsof collar"'.'I3,,' exceptingportioni i thereof, being ..attached to surface Sfiipf theseal by any appropriate adhesive or bondinginaterial.

Conversely thedispenser a e ro t u v t e Pmniaaand the collar portion may ,then be caused toadhere tothe under. surface ofthe seal. In this latter situation, it -may be desirable; to provide for -meansto receive the apex-port ion 66 of the dispenser, as by affixing an independent slit to the surface ofthe seal, orbydevising ;a pocket adapted "to receive said apex -;portion "between the collar and the under surface of the seal, in
accordance-with the -"details 'ofconstruction as described: in connection with Fig-3 hereinabove. Dispenser -18=-may beeflectively provided with crease-or fold linies'similaito those shown in Fig.
8. The crease and fold lines designated on Figs.
11 and 15 have been numbered similarly to the,
corresponding means shown on Fig. 8, and since the functioning is essentially the same, no additional consideration is directed to the manner of collapsing dispenser I8.
Although the crease or fold lines and the features relating to collapsing the dispenser modifications shown in Figs. 1-17 have been described in generally similar details, there is no intent to be restricted to these illustrative characteristics of the invention. Variations in the positioning of the fold or crease lines will be apparent to one skilled in the art without deviating from the features of the present invention. Thus the fold lines shown on the respective lateral walls of the dispensers described may be reversed to attain an overlapping of the dispenser walls in the reverse direction. Referring to Fig. 8 by way of illustration, the crease lines occurring on lateral wall can be instead applied to wall 45, while that on the latter would be provided on wall 45. Under these circumstances, Wall 45' would be caused to overlap itself with wall 45 overlying wall 45 on collapsing the dispenser. Similarly the particular design of the dispenser may be subject to change without avoiding the inventive features herein. Likewise the slit or means for retaining the apex portion of the dispenser may be subject to substantial variation, or even omitted within the purport of the present disclosure.
The dispenser modification of Fig. 18 is also applicable for attachment to any appropriate seal opening. This dispenser I9 embraces the funnel portion TI which may be of substantially tubular configuration having a curvilinear surface; however there is no intent to be restricted to any particular form or shape for this funnel modification.
Desirably base portion 8| is comparatively large with respect to the outlet or discharge opening 82, but this dimensional distinction is not essential since inlet opening 80 and discharge end 82 may be of similar dimension. The funnel assembly may be afiixed to the seal by projecting it through any predetermined opening of a size comparable with the base portion 8|, and causing the flanges 83. coated with adhesive of any type, to adhere to the under-surface of the seal, in appropriate coordination with the seal opening. Alternatively funnel I9 may be affixed to the seal through the expedient of a collar superimposed on and attached to flanges 83, and coordinated with the seal opening, or by directly attaching the flanges to the seal. Where the seal opening is larger than base portion 8| of the dispenser,
flanges of appropriately large dimension or a collar of appropriate size bonded to the flanges may be relied upon to obviate the dimension discrepancy.
When not in use, the funnel may be collapsed by bringing rear wall surface 84 into a contiguous relationship with portion 92 of front surface wall 35 along crease lines 86, located on opposite longitudinal surfaces, these contiguous surfaces being essentially vertically disposed from crease line 99 upwardly when extended relative to the dispenser base. The lower portion 9| of the funnel, primarily embracing the front surface from the base to crease line 90, is at the same time folded to a substantially horizontal plane along lines 87, 88, 99, being in effect pivotable relative to base 89 and flattened toward base portion 8|. By further folding the thus collapsed funnel along crease line 99, the upper portion 32 may assu a substantially horizontal position in superimposed relationship to the lower portion surface 9| of the funnel, or it may assume an acute angular disposition with respect to said portion 9 I In order to diminish the length of the dispenser in its collapsed horizontal position, and to afford a closure means for preventing the passage of any powder through the funnel, the apex portion is desirably folded on crease line 93 to overlie or be angularly disposed relative to front wall surface 92. Accordingly when the funnel is fully folded and collapsed, the folded apex portion may be positioned in proximity to, although not necessarily contiguous the base portion of the dispenser. Alternatively the apex portion may be folded on crease line 93 toward the back wall upper surface portion 92' of the funnel. In any event, this dispenser device may assume a compact form of comparatively small area, and dependent upon the fold lines and details of creasing resorted to, it may be substantially in the same plane as the seal surface or angularly disposed relative thereto. This modification obviates the necessity for a retaining slit to hold the dispenser apex in closed position when collapsed.
An illustrative blank for making this funnel modification is shown in Fig. 180.. It may be a conventional sheet of appropriate material of preferred fabrication, the requisite being that it is susceptible to folding or bending in accordance with the requirements of the invention. The sheet may be rolled to the shape generally indicated by Fig. 18a, with its edges 94 desirably overlapped to a sufficient extent for permitting the permanent attachment of the overlapped portions by adhesive or the like. Inlet end 89 of the tube may be comparatively large with respect to discharge end opening 82, although it is not intended to be restricted to this particular configuration since ends 89 and 82 may be of substantially equivalent dimensions. The protruding portion which may occur at either or both ends of the blank may desirably be cut off to provide the substantially uniform circular inlet and/or outlet opening. At the opening 89, slits 83 are cut to form flanges 83. It is then merely necessary to provide the crease or fold lines as previously indicated, in order to position the flanges at substantially right angles relative to the lateral wall surfaces.
The structural modification shown in Figs. 19-22 provides another desirable embodiment of dispenser device. The dispenser 95 may be of rectangular cross-section which is in an open position, and is provided with pleats 96 in its side walls 91, whereby walls I94 and I05 may be positioned substantially contiguous each other on collapsing the dispenser. The base portion of the dispenser has two overlapped flanges 98, 99 on each side. the overlapping attained through the expedient of causing the under-surface of flange 98 to adhere, as by resort to an adhesive material, to the upper surface of flange 99, or vice versa. The other two flanges are designated as I99 and IOI.
The cross-sectional detail shown in Fig. 20 indicates the attachment of the flanges to the under-surface of the seal I02. By resort to a crease line I03 at the lower portion of wall I94, the dispenser lends itself to closing merely by causing it to assume a horizontal position contiguous the surface of the seal. A secondary closure, to obviate the possibility of any powder issuing through the dispenser in its closed position, may be attained by folding walls I95, I95, when the dispenser is in collapsed position, along crease or fold line I96 at the upper portion of wall 105; although it will be understood that a complementary crease line 101 will similarly be present on wall Hl4- with creasedines I06. and lfil coincidingiwitheach other.
The discharge end ofthe. dispenser maythus substantially overlie-wall-|65,or if desired wall H34, in the event-thedischarge end is: folded in the reverse-direction. It may quite efiectively serve as adispenser closure however by being angularly= disposed relative to saidwall M35 or even wall I-M. Without int-ending to' here- 'strictedto any particular-angular relationship between the discharge endand the wall-surfaces of the dispenser, a right angle or anacute angle have both provided satisfactory results-as a-clovJsure expedient. Where a'container cover. is conrtemplated, the positioning .of the cover over the seal and the dispenser coordinated therewithwill not necessarily afiect thisangularly disposed relationship between the dispenser dischargeand the collapsed walls in-view of the usual space --which occurs" between ithecover and the. seal.
'At the mosh-the discharge end will be caused to c'ontact'the adjacent --wal1 surface-as a-result of the container cover forcing .thedischarge endtoward the saidwallrsurface.
