2 Claims. (Cl. 222-192) This invention relates to a powder dispenser in the broader aspects thereof.

More specifically, this invention relates to a scoop for use in connection with a compact mechanical dispenser for face powder which may be easily carried in a womans purse.

This application is a division of my copending application, Serial No. 252,163, filed October 19, 1951, now Patent No. 2,706,583, datedApril 19, 1955, and relating to a Powder Dispenser.

One of the objects of the present invention is to provide a powder carrying dispenser having valving means therein which definitely cuts oi the powdersupply and to the provision of a powder scoopconstnlcted and arranged to be housed and nested within the dispenser body and available for use at all times when it is necessary to refill the dispenser with a fresh supply of face powder.

Another object of the present invention is to provide a powder dispensing means wherein the mechanical dispensing and valving structure may be bodily removed therefrom as a unitary assembly for periodic cleaning purposes, and particularly at times when the face powder is changed from one type and color to another type and color, with the powder scoop lof the present invention providing a simple and easily removable means to permit the removal of the mechanical dispensing and valving structure from within the dispenser.

lt is a further object of the present invention to provide a scoop which can be carried with a powder dispenser and which is seated and housed therein and held in place by the cover supplied with the dispenser and which scoop does not in any way interfere with the general capacity of the entire dispenser.

As another object the present scoop is designed and adapted particularly for filling a dispenser body with powder and in such a way that the powder will be brought into the dispenser without the use of other guiding or funnelling means and which scoop can be emptied and tapped out without having the powder dissipated into the atmosphere from within the powder dispenser per se.

Attention is also directed to the fact that the powder scoop as a further object is arranged to provide an auxiliary cover for the purpose of enclosing the filling end of the dispenser and which is provided with suitable abutment means to deinitely position the scoop in` its inoperative and housed position within the dispenser body and with the scoop hugging the interior walls of such body leaving the central portion of the dispenser open and free for storing powder.

Other objects and advantages relating to a powder lling scoop for a powder dispenser of the present or analogous constructions shall hereinafter appear in the following detailed description having reference to the accompanying drawings forming a part of this specication.

Figure 7 is a fragmentary longitudinal cross sectional view on a medial plane of a modied construction of powde'r'dispenser using a slightly different arrangement of valving and dispensing structure; and

Figure 8 is an enlarged bottom end View of the dispenser illustrated in Figure 7 to show further details of construction thereof.

The dispenser illustrated in Figures 1 to 6 inclusive comprises a container 1 having a powder barrel 2 and a closure cap 3 with a dispensing mechanism 4 carried within the barrel 2. The dispensing and valving strucassembly having a stem 5 guided within the tube or barrel 2 by means of an upper winged spider 6 and a lower winged spider 7, with the stem 5 terminating in a valving and dispensing head 8 as best illustrated in Figure 2.

"The valving and dispensing head 8 cooperates with the lower end of the barrel 2 which terminates with a conical bottom 9 having a cylindrical port 10 formed therethrough. .The head 8 comprises a Valve actuating stud 11 which depends from a cylindrical cutoff valve 12 connected with an upwardly tapered cylindrical dispensing boss 13. VThe winged spider 7 is suitably secured to the boss 13 while the winged spider 6 is slidably carried upon an upper end 14 of'the stem 5. The upper end 14 of stem 5 carries a retaining pin 15 in an opening 16 which will normally prevent outward movement of the winged spider 6 when the dispensing and valving mechanism is removed from the barrel 2. An expansion spring 17 is interposed between the valve head 8 and the upper winged spider 6 to normally carry the valving structure inoperative relation with respect to the conical end 9 of the barrel 2.

The entire dispensing and valving structure 4 is assembled withthe barrel through the upper end of the latter with the Wings 18 of the winged spider 7 directed inwardly into the tube 2 out of registry with a plurality of retaining projections 19 that are formed radially inwardly in the wall of the dispenser barrel 2. Y

ln the same fashion, the wings 20 of the upper winged spider 6 may also be angularly displaced for movement lengthwise of the barrel and out of registry with the projections 19 to a position below the projections at which tiniesthe yspider 6 may be slightly rotated in line with `the projections 19. Then under the action of the expansion spring 17, the upper spider 6 will' be locked against endwise outward movement of the barrel 2 by reason of ,the connecting engagement with the projections 19.

Outward movement ofthe head 8 and its associated parts under the action of the spring 17 will be prevented by the feather edge shoulder 21 which engages the upper peripheral edge 22 vof theport 101formed in the conical end 9 ofthe .barrel.2. The vertical distance between the feather edge :shoulder `21when seated, in the barreland the plane of the three projections 19 is such that the spring 17 will be held by the spider 6 to urge the head 8 in the closed position and so that the spider 6 is out of engagement with the retaining pin or means 15. i

The dispensing device may be operated by forcing the entire container downwardly upon a suitable surface such as a powder puit 23 with the actuating stud 11 in contact therewith, which will cause an upward movement of the entire stern Sand its connected parts against the expansion spring 17. This dispensing operation may be accomplished with the device held in generally vertical position as shown in full lines in Figure 5, or the dispenser may be operated in any tilted position for axial operation as best illustrated in dot and dash lines in Figure 5. Such tilted operation is made feasible by the use of the conical end 9 on the barrel 2. When the dispenser is operated, the cutoff valve 12 leaves the port 10 and the stem 5 will then be centrally guided within the barrel 2 by means of the cooperative spiders 6 and 7 thus keeping the dispensing parts in their coaxial relationship within the barrel 2.

When the valving structure 8 is raised as shown in Figure 5, some of the powder may drop out through the annular port 18', but a greater portion of the dispensing action occurs when the valving mechanism moves outwardly under the action of the spring 17 as the barrel 2 is raised upwardly from the powder puff 23. This is due to the collective action of the winged spider which does stir and iuff the powder at the dispensing end of the container together with the conical boss 13 which does create a limited amount of action downwardly and laterally through the powder together with the shoulder portion 24 of the terminal end of the cut-off 12. As the cut-off 12 again leaves the port 10, the flow or discharge of powder is deiinitely stopped since the diameters of the port and cut-off 12 are substantially equal to only allow a sliding tit. As the head 8 descends to close the valve, the feather edge shoulder 21 strikes the inner peripheral edge 22 of the conical end 9 of the container stopping further outward movement of the dispensing mechanism. Since this edge 21 presents an upwardly and outwardly tapered adjacent area with a very fine knifelike shoulder that prevents packing of the powder in the area and vicinity of the valve cut-olf structure, the shoulder 21 is substantially free from any interference of packed powder under all normal conditions of operation.

If for any reason the valving and dispensing mechanism 4 is to be removed such as to clean the same when changing powder, it is only necessary to move the spider 6 downwardly free of the projections 19 and to turn such spider upon the stem 5 to permit movement of the latter t through the barrel 2 and between the projections 19 best illustrated in Figure 3. It should also be noted that the spider 6 has its wings deformed to provide upwardly concave portions 25 which provide convenient centering means to assist in locking or removing the dispensing means from the projections 19.

This dispenser also includes an ever ready under the cover means for readily lling powder into the barrel Z comprising a scoop 26 having a body 27 of cylindrical outline and diameter to substantially t the internal diameter of the barrel 2. The end wall 28 of the scoop 26 terminates in a peripheral bead or lip 29 as best shown in Figures 2 and 6 for the purpose of providing means to overhang and abut the end of the barrel 2 and to provide an annular nger grip for conveniently removing the scoop 26 from the end of the barrel 2 after the removal of the closure cap or cover 3 proper.

By taking a scoopful of powder from a supply and guidingthe forward end of the scoop into the barrel 2, which may preferably be held in a near horizontal position during the insertion of the scoop, the filling operation is conveniently and quickly accomplished without spilling of powder. Furthermore, cylindrical body 27 of the scoop 26 hugs the barrel 2 and permits the free vertical operation of the dispensing unit without structural-interference vand the scoop does not encroach upon the capacity of the 2 to counteract the loss of face powder through this end of the barrel if the cover 3 should be accidentally removed or dislodged. The scoop per se may serve as the principal cover for the barrel. Both the cap 3 and scoop 26 together do, however, form a combined powder seal structure for the dispenser.

The scoop 26 by being built with a body portion to conform to the shape of the container such as the powder dispenser body 2 will efliciently and completely cause the powder to be inserted into the dispenser body or barrel without spilling and without the use of a funnel or other auxiliary means for the filling operation. Also, by the 'particular construction wherein the scoop forms a closure means for the open end of the dispenser, it is possible to insert the scoop into the dispenser barrel and to the'abutment rim 29 formed on the scoop. Then the scoop may be tapped to release the powder for dropping into the barrel while holding the entire unit in upright position. Since facepowder is particularly of such a character and consistency that it readily packs, the closing of the dispenser with the scoop and the subsequent tapping of the scoop helps to dislodge all the powder from the scoop to discharge it into the contines of the container.

At the same time, loose powder that may be in the unfilled space portion of the dispenser will be held restricted to that area of the dispenser giving the air borne powder an opportunity to settle within that area before removing the scoop to pick up another supply of face powder. Thus the scoop also aids in preventing excessive dusting of the powder which will largely beconned to the limits of the barrel.

Referring now to .Figures 7v and 8, the dispenser here shown comprises a barrel 30 terminating in an end 31 having a cylindrically walled port 32 formed therein. This barrel also has inwardly formed projections 33 to engage the wings of a spider 34 that is carried upon a stem 3S forming a part of the dispensing and valving means 36 of this modified construction. ln this case the valve head 37 also comprises an upwardly and outwardly flared powder dispensing boss 38 having a feather edge shoulder 39 to seat upon the upper peripheral terminal edge 40 of the port 32. As best shown in Figure 8, the valve head terminates in an outwardly projecting actuating stud 41 having a plurality of flat side walls 42 connected by the cylindrical portions 43 which depend from the cylindrical cut-off valve 44. With the use of the squared end such as 45 having the flats and curved surfaces described, shoulders such as 46 are formed about the square end 4S at the port 32.

During the operation of this dispenser, the squared end-45 is moved inwardly whereupon this end of the dispenser comprising the head 37 is guided by means of the surfaces 43 within the port 32. When the squared end 45 is vertically displaced with the cut-off valve 44 out of contact with the port 32, a powder dispensing area is produced equivalent to the collective areas of the segmental shoulders 46 inasmuch as the squared end 45 provides segmental openings between such end and the inner peripheral cylindrical wall of the port 32.

ln this construction, an expansion spring 47 also maintains the parts in their operative relationship as in the form previously described. lThis construction only uses one spider 34 adjacent the upper end of the stem 35 since the head 37 is guided within the port or opening 32 by means of the surfaces 43 to prevent dislodgernent of the head 37 from its operative engagement within the port 32. A shoulder 48 is provided on the stern 3S for engaging the extended sleeve 49 that is carried upon the spider 34. This stops the upward movement of the valve head 37 when the bottom surface 5t) of the squared end 45 is brought into alignment with the bottom surface 51 of the container 30.

The dispensing and valving parts are also retained in their assembled relationship by means of a suitable pin 52 carried by the stem 35 so that these parts may also be bodily removed from the container for cleaning purposes.

Attention is directed to the fact that the dispensing boss 13 and the upwardly tapered dispensing boss 38 in both forms provide means for moving the powder laterally outwardly and away from the area of the ports and 32 respectively. This action assures seating of the feather edge shoulders 21 and 39 under normal conditions of operation.

It should also be further understood that the modiiied construction may be made to dispense more or less powder under the segmental structure of the squared end 45 by changing the radial locations of the ats 42, thus enlarging or decreasing the shoulders 46 which move the powder from within the container 30 outwardly through the port 32.

With the description of the particular powder dispenser being directed to the specic form illustrated in the drawings and incorporating the particular scoop structure best shown in Figures 2 and 6, it should also be understood that the dispenser may take a different external form and that by the same token the exterior contour of the scoop comprising the body 27 may also be formed to assume the same shape as the barrel of the dispenser. This will again permit the same operation and utility of the improved design of scoop over any other form of lling implement which may be used as an accessory or a separate item and which has no unitary part or 'association with the particular dispenser. The scoop of the present invention is always carried with the dispenser and is never lost or mislaid, and as previously pointed out, forms an auxiliary cover for the unit which would prevent loss or spillage 0f powder in the purse of a user in the event that the usual or normal cover 3 should become dislodged from the end of the dispenser. Furthermore, although the scoop is also shown as having the particular half shell forward end, it is also possible to produce a complete cylinder without the side entrance portion if that is desired, and this should come within the purview of the concept of the present invention.

Further changes and modifications are also contemplated in the scoop means of the present design and invention for powder dispensers. However, any changes and modications that shall be made will be governed by the breadth and scope of the language of the claims appended hereto.

What I claim is:

1. In a powder dispenser, an open ended powder receiving barrel, a powder scoop for filling said barrel and a cover for the barrel, said scoop being removably housed within the open end of said barrel, and said cover being adapted to close said barrel and to conceal said scoop; said barrel, scoop and cover all being tubular in cross section for telescopic nesting respectively, said scoop having an external peripheral lip thereon to rest upon the edge of the open end of said barrel and terminating diametrically substantially coincident with the exterior diameter of said barrel, and said cover being arranged for sliding fit with the powder barrel and in clearance relation with respect to said peripheral lip of said scoop.
