(Cl. 221-104) This invention relates to an improved dispens limiting the amount delivered to the same quan ing device to deliver a predetermined amount of tity at each delivery. crystalline, granular or pulverized material. The The slide is bent over at the top, as at 26, to device is particularly adapted to deliver small form a ?nger piece and is spaced from the top of 5 quantities of such materials and may be em the body portion to form a housing. Inside this 5 ployed by pharmacists in making up prescrip housing is the spring 2| interposed between the tions or may be used by individuals using small receptacle and the housing.’ The receptacle is quantities of ‘materials or preparations in crys usually provided with a seat 22 for the spring talline granular or pulverized form. which holds the spring in place. 10 The object of the invention is to prove such The slide is carried down beyond the housing 10 a dispensing device which can be easily and in to the rear face of the receptacle as at 23. The conspicuously manipulated by one hand, and can body portion In is recessed at M and the end of be cheaply manufactured in a multitude of sizes, the rear part 26 of the slide is bent over to form which is attractive so that it can be used as a a stiff lip 25 which rests in the recess 24. The 15 sales package and which can be so assembled ends of the recess act to limit the movement of 15 that it can not be re?lled without distorting it. The invention is illustrated in the accompany ing drawing, in which Figure l is a side view of a dispensing device made according to my in 20 vention. Figure 2 is a front view of. the dispens ing device shown in Figure 1.‘ Figure 3 is a cen tral vertical section of the device shown in Figure 2. Figure 4 is a section on line 4—4 in Figure 2. Figure 5 is a detail section of the lower part of 25 the device with the delivery of material accom plished. Figure 6 is a detail section of the upper part of the device showing one method of secur ing the slide to’ prevent the re?lling of the cham the slide when the slide is pushed down and when it is returned to normal position by the spring 2|. In operating this dispensing device it is held in an upright position between thumb and mid dle ?nger of the hand. The index ?nger is then 20 pressed down on the ?nger piece 20 and the yielding support of the spring 2! is overcome. The slide descends and carries the material con ber. 30 , l The device is composed of a receptacle and a tained in the cup Hi from the position shown in Figure 3 to the position shown in Figure 5, where 25 it is discharged by gravity. In Figure 6 is shown a dispensing device which is non-re?llable. The rear part 26 of the slide is provided with a slot 21. The headed screw or rivet 28 is located ‘in the slot and as it is secured 30 slide, the receptacle being preferably made of ?rmly in the body of the device it acts to hold material that is light in weight and that can be the slide against removal and in addition it acts to limit the movement of the slide. Various changes can be made in the form and molded, the b'akelite type being preferred. The slide is preferably made of sheet metal. 35 The receptacle may be made of three pieces, a body portion l0, and side pieces I I, all three held together permanently by rivets I2. The body portion is provided with a chamber l3 for material M, the chamber being open at 40 the front and having an inclined bottom l5 to direct material toward the front when the device is held upright. The side pieces II are provided each with a groove I6 in line with the front of the‘ body por 45 tion I0. The slide l1 ?ts these opposed grooves and forms the front of the chamber l3. The slide ‘ is normally ?ush at its bottom edge with the bot tom of the chamber l3 and has a measuring cup 50 I8 of varying size and shape opening inwardly into the chamber l3 and normally in position at the bottom of the inclined bottom [5 of the cas ing. The casing has the ?at bottom face [9 across which the cup passes to wipe material 55 from the cup as it passes when pushed down thus proportion of the parts without departing from 35 the scope of my invention. I claim: 1. A dispensing device comprising a receptacle, 2. flat slide of sheet material forming the front of the receptacle and slidable on the receptacle, 40 said slide bent over at the top, and a spring in terposed between said top and the upper part of the receptacle, the lower part of the slide having a measuring cup open to the interior of the re ceptacle when in normal position. 45 2. A dispensing device comprising a receptacle, a slide of sheet material forming the front of the receptacle and slidab-le on the receptacle, said slide being bent over at the top, and then down to engage the back of the receptacle to form a 50 housing, and a spring in said housing for yield ingly holding the slide in normal position, said slide having an inwardly opening measuring cup positioned to be at the bottom of the interior of 55 2 2,112,043 the receptacle when the slide is in normal posi tion. 3. A dispensing device comprising a receptacle open at the front, a slide forming the front of the receptacle and including a measuring cup opening toward the receptacle, being normally open to the interior of the receptacle and mov able to a point beyond the receptacle, the slide being bent over at the top to form a ?nger piece 10 and spaced from the receptacle to form a housing, the receptacle having a recess in the back, the end of the slide being bent into the recess to form means for limiting the amount of move ment of the slide, and a spring interposed be 15 tween the receptacle and the ?nger piece to yieldingly hold the slide in normal position. 4. A dispensing device comprising a receptacle having a body portion open at the front and hav ing a bottom inclining toward the front, the body portion having a recess on its back face, side pieces secured to the body portion and extending above the body portion and having grooves in line with the front face of the body portion, a slide in the grooves and forming the front of the re ceptacle and having a cup opening into the re ceptacle and normally at the bottom of the in clined bottom of the receptacle, the slide being 10 bent over at the top and spaced from the body portion and having its end bent into, the recess of the body portion and a spring interposed be tween the bent-over top of the slide and the top of the body portion.
