JOSEPH WOROBLE G ATTORNEY United States Patent Ofifice 3,168,966 Patented Feb. 9, 1965 3,168,966 DISPENSER ANCHORING SYSTEM Joseph Womble, North Arlington, NJ. (834 Kearny Ave., Kearny, NJ.) Filed Apr. 8, 1963, Ser. No. 271,287 1 Claim. (Cl. ZZZ-90) This invention relates to means for anchoring a dispenser to the wall of a package. More specifically, it deals with barb-type anchoring means employed in cooperation with a cutter or spear of a powder dispenser which is attachable to the wall of a cardboard container, for example.

In recent years, there have been developed dispensers for dispensing powder, e.g., granulated detergent, from a membraneous container, such as one made of cardboard, similar to the dispenser described in US. Patent No. 3,080,095. These dispensers are provided with piercing and cutting spears for making an opening in the wall of the container. These dispensers are held in attached condition to the box by means of an encircling elastic band, the ends of which are attached to the sides of the dispenser, or by other similar holding means. One objection to such holding means is that they are cumbersome and unsightly, as well as expensive. Other objections include the necessity of expensive and bulky mountings for the ends of the bands, insecure holding on small or very large containers, etc.

According to the present invention, these disadvantages are avoided or eliminated by use of barbed projections mounted on the bottom of the container on the outside of the cutting spear, as will be outlined further.

The invention will be more readily understood by reference to the accompanying drawing in which FIGURE 1 presents a side view, partly cut away, of a bottom portion of a powder dispenser, incorporating the new device, while FIGURE 2 presents a bottom view thereof. FIGURE 3 illustrates a side view, partly cut away, of a bottom portion of a powder dispenser, incorporating a difierent modification of the new device. An enlarged side view of a different type of barb employed in the present invention is depicted in FIGURE 4. Similar numerals refer to similar parts in the various figures.

Referringagain to the drawing, numeral 4 represents a cylindrical dispenser, made of plastic or similar material having cemented thereto, at its bottom end, a wider cylinder base 5 provided with sidewise-projecting lugs 6 and 6, preferably having their bottom portions 7 and 7' disposed in flush relation with the periphery of bottom 8 of cylinder 5. The bottom 8 of cylinder 5 has a central opening 9 into which is tightly fitted the hollow metal cutting spear l0.

Spear 10 also has two sharp downwardly-directed prongs 11 and 11' which are designed to be jabbed and turned into the wall of the carton from which the powder is to be dispensed. Bottom 8 is provided with projecting shoulder 26 immediately surrounding spear 10 and serving as a sealing means to prevent egress of powder through punctured opening 27 in wall 20 of the carton. This shoulder 26 preferably is provided with at least one concentric groove 28 (FIG. 2) disposed at about the middle of its bottom to further improve the sealing operation and prevent leakage of powder through pierced and cut opening 27 in container wall 20. Since circular shoulder 26 projects beyond bottom 8 and is disposed at a distance from barbs 15, the barbs pull the wall 20 of the container toward bot-tom 8 (with which they are almost in flush relation) so that wall 20 is tightly pressed against shoulder 26, and any slight movement of dispenser body 4, independent of wall 20, will not loosen the tight fit of wall 20 against shoulder 26 to permit granules to escape from the container. In the event a small amount of granules do for some reason make their way under shoulder 26, they would be entrained in groove 28, so that they will not litter the counter or shelf on which the container is placed.

Lugs 6 and 6' have a threaded hole 12, widened at the bottom, as widened hole 13,10 provide'a shoulder14. Into the hole is screwed barb 15 having a screw upper portion 16, and a wider seating portion 17 therebelow, which seats on shoulder 14 of lug 6. Below wider portion 17, barb 15 extends as a narrower extension 18, projecting below lug bottom 7', and terminating at its bottom with a downwardly-pointed barbed tip 19. Narrower portion 18 of barb 15 projects downwardly sufficiently to accommodate the thickness of sheet 20 (wall of the package) to be penetrated. Since the upper portion of barbed tip 19 is wider than the adjacent narrower portion 18, it is aparent that barb tip 19 would not be removed easily from the carton (once penetrated), and would require a strong pull or tug.

When in use, the spear points 11 are jabbed into the wall 20 of the container containing the powdered detergent, or the like, and the dispenser 4 is twisted until a circle 21 is cut, the inner cardboard portion of which is removed, leaving a hole into which the spear 10 is pushed further. Then, one of the metal barbs 15 is jabbed into the wall 20, and the oppositely-disposed barb also is jabbed in, resulting in a strong locked mounting for the dispenser. Powder from the container is fed through opening 22 into the dispenser 4 for measuring and dis, charge thereof.

It has been found that, although the barbs 15 give an excellent anchorage for the dispenser, if, for some reason, the dispenser is pulled away from the container, it can be reanchored thereto by jabbing the barbs into a different area around spear 10. One desirable feature is that when the dispenser is pulled away from the container, the holes, in which the barbs were anchored, become sealed 'by projecting cardboard fragments sufliciently to prevent other types of barbs and barb mountings may be used.

For example, FIGURE 3 shows a dispense-r 4 in which the dispenser bottom 7 has holes 23 into which are cemented pegs 24 of hard plastic. These pegs have pointed protruding ends 19' and, above the points 19, are round beads 25 circumscribing pegs 24 which make up the barb for anchoring the dispenser.

Another type of barb which may be used with a container, such as that depicted in FIGURE 3, is illustrated in FIGURE 4. This barb 15' may be made of die cast metal, and peg 24' is provided on its outer surface with a multiplicity of downwardly-directed circular fins 28 which have a diameter slightly larger than that of hole 23, so that, when barb 15' is forced into hole 23, the projecting fins anchor the peg in the walls of the hole and prevent withdrawal of the barb when the dispenser is removed from an empty carton, for example;

I claim: A powder dispenser anchorable to the wall of a membranous container, comprising,

a hollow dispenser body having a bottom, and having an opening in said bottom for receiving powder from a container for dispensing powder through said dispenser, I

a hollow piercing and cutting'member projecting outwardly from said bottom and disposed adjacent said opening and designed, when the body is rotated, to

3 cut a hole in a container to permit passage therethrough of a powder into said body, narrow continuous shoulder projecting from said bottom and disposed immediately adjacent and outside said opening and said piercing and cutting member-,and having a continuous groove therein, and servingas a powder sealant, pair of oppositely-disposed prongs, each having a round body, and terminating with piercing points, and projecting from the bottom of said dispenser outward of said groove, and bulged-portion disposed adjacent and above said points on said prongs, forming a barb therewith, and

serving as a stop for resisting removal of said'body once said barb has penetrated a wall of a container.
