. 12 Claims.
adapted to be used with containers for finely divided powder-like substance, one example of which is tooth powder.
In-dispensing tooth powder from a cylindrical can or container in which it is usually held, a
largelportion of the powder islost and does not deposit on the brush but failstherefrom and is not used. With my invention the dispensing of the tooth powder and depositing it. upon a tooth brush is very quickly, readily and easilyattainedand with the loss of very little or none of the] powder, substantially all of the same being readily and easily deposited upon thebrushand'not falling past the brush.
For the attainment of theseends I have produced a very simple, economical, easily operated. and particularly practical powder dispensing top or coverto be-appliedto the upper end of a containerfor finely divided powder, suchas tooth powder, understanding of which may berhad from the following description, taken inconnection-with the accompanying drawing, in which, Fig. 1 is a perspective view of a receptacle for tooth powder equipped with 'thedispensing top or cover. of my invention.
Fig.3 is a fragmentary somewhat enlarged vertical section through the container, the dispensing mechanism being shown inside elevation.
V 'Fig. 3 is an underplan view of the dispensing top with the mechanism for dispensing the powder mounted thereon. 1 .Fig. 4 is a similarview, but with one of the elements broken away-and shown partly in cross section for a better disclosure of the construction. 1
Fig. 5 is a perspectiveview of the .two main parts of the mechanism designed tobe mounted within" and at the underside of the top.
Fig. 6 is a plan view and Fig. 7 is a fragmentary vertical section illustrating a slight .modification in the structure of theItop for greater ease of assembly of the parts, and ,7
. Fig.8 is a fragmentary sectional view taken in a plane circumferentially of the container shown in Fig. 1, through the opening 4 thereof, illustrating a slight modification 'inconstruction of the discharge opening.
Like reference characters refer to like parts 'in the differentfigures of the drawing. v
'The cylindrical container 1 for the powderis of usual form, to which is applied a cover having a horizontal upper side 2 and .a depending annular flange 3, inone side of which a somewhat elongated opening 4 is made through which thejpowder is ejected from the receptacle.
A-mem'ber '5Qof sheet metal is formed at its inner end with a lip 6 turned at right angles therefrom, .and'h'as an elongated slot '7 therein parallel to the sideedges of the member 5 and substantially midway between the same. At one side'of the member '5 and near 'itsmiddle an arm 8 extends outwardly from which a second arm 9 is turned at right anglesterminating in a hook 10. At '"the same side of the member 5 and between the'arm '8 and the lip 6 described'a tongue ll'is turned at right angles spaced a short distance from the adjacent edge'of the arm .8. Two tongues 12 and I3 are formed integral with the member 5, the tongue 12 at the same'side as the arm '8 while the tongue 13 is. struck from the member '5 at the opposite side edge.
From the center of .the upper side '2 of the top or cover a lpin. 1'4 depends passing through the slot? in the member 5. The annular flange of the top or coverhas' a narrow opening of sufficient width and length that the end of the member -.5 maybe inserted therethroug'h so as to project outwardly diametrically opposite the opening 4. Said member 5 7 may 'be moved through said s'lo't until stopped by the tongue 13 coming against the inner side of the annular flange '3. j
A second 'U-shaped member of sheet metal is providedv having an upper side l5, of the form best shown'in'Figfi, from which a curved tongue 16 extends at one side lying 'inthe same plane as the .part.15. This member is formed into substantially ll-shape, having a connecting portion 17' bent at'right ang les from one end of the part 15 'for a short distance, the metal being then bent "back under and parallel to the member 15 as indicated at 18, said part '18 terminating in a lip 1'9, the outer "face of which is curved to cone form substantially to the inner curved surface of the flange 3.
Alined openings are made through the parts 15 and 18 so thatthe member maybe placed over the pin 14. When thuslocated the lip 19 coversthe opening 4 and the tongue 16 passes between the tongue 11 and the lip 6 'as shown in Fig.3.
A coiled spring '20 is located over the arm 9 and above the hook '10 which keeps the same 9 from being accidentally disconnected from said arm. One end 521 of the. wire from the coiled spring "ZO isma'de engaging against the tongue 12 (Fig. 3) while the other end extends to and seats in .a groovemade around the pin 14.
With the parts assembled as described, the effect of the spring is to move the member 5 outwardly until the stop 13 engages against the flange 3 of the cover. The lip 19 closes the opening 14 and the powder material within the container is held from escape. The member 18 is provided with an opening 28 therein so that on inverting the container the powder will pass through said opening and around the edges of the part 18 so that a portion of the powderwill be between the lips 6 and 19.
Pressing upon the projecting end of the mem her 5 causes said member to slide inwardly over coming the spring. With such inward sliding movement the tongue 11 engaging against the tongue 16 turns the U-shaped member to the position shown in Fig, 4. This turning movement of the U-shaped member occurs in the forepart of the inward sliding movement of the member 5, after which the end of the tongue 16 bears against the inner side of the tongue 11 as shown in Fig. 4. Such turning movement of the U-shaped member moves the lip 19 to uncover the delivery opening 4 through which the powder is forced by the continued move: ment of the member 5, the lip 6 being back of the powder and forcing 'it outwardly through said opening. When the powder has been thus ejected and deposited upon an article, such as a tooth brush, a'release of the member 5 permits it to return to its original position under the force of the spring, and the outer curved edge of the tongue 16 and adjacent parts of the part 15' being" engaged by the lip 6, the U-shaped member is turned back to its originaliposition' wherein lip 19 covers the delivery opening 4.
In Figs. 6 and 7a slight modification in the shape and form of the cover is shown. That is, the flat upper portion 2 of the cover near one side is downwardly beveled as indicated at 264 and an opening 24 made therein considerably wider than the opening made in the flange 3 to pass the end of the member 5. Said opening 24 in the bevel permits a very ready and easy assembly of the slide member 5 as the same'can be inserted therethrough in a position like that indicated in dottedlines in Fig. 7. Then when turned to its full line position the opening 24 is substantially closed 'so that the powder cannot escape therethrough, Such form is more convenient for assembly of the parts than that illustrated in Figs. 1 to 6, inclusive.
In Fig. 8 the metalaround the edges of the opening 4 is pressed slightly inward, as indicated at 4a, whereby the curved lip 19 rides against said edges and not with its entire surface. against an inner curved surface of the flange 3. This constructionfis preferred as it insures against any likelihood of freedom of movement of the lip 19 being restricted through powder lodging between said lip and the surface over which it moves.
The construction described is very simple, economical and'practical. It is jreadily made and quickly and easily assembled and with it waste of powder is substantially eliminated While the construction has been illustrated with the opening 4 in the downturned flange of a top to the receptacle 1', itis evident that tops without downturned annular flanges may be used to close the upper ends of receptacles and that the mechanism for dispensing the powder may be mounted on a substantially fiat plate top and the powder ejected through an opening made in the receptacle wall adjacent the end of a receptacle closed by such character of top. The invention therefore is not to be restricted to the specific disclosure made, but is to be considered comprehensive of all forms of structure coming Within the scope of the claims hereto appended which define the invention.
