Definitions

  • Such current pumps are of the "draw up” type, i.e., the product to be dispensed is loaded above the piston and the piston, via the aforesaid means, is pulled up against the product to force it out of the pump nozzle.
  • an important object of this invention is to provide a new pump which is less complicated and therefore less expensive than those currently in use.
  • Another object of this invention is to provide a pump for paste products wherein the piston is located above the product to be dispensed and wherein there is provided a source of constant downward pressure on such piston so that the product is forced up a tube passing through the piston whereby, when the nozzle or spout is in registry with the tube, the product flows out continuously until the nozzle is closed.
  • Another important object is to provide, in connection with the above combination, a rotatable turret type spout or nozzle which has an opening therein, and wherein the opening can be moved in and out of registry with the tube.
  • Another important object of the invention is to proide a pump which is refillable, i.e., to provide a "basic" pump which is designed to receive a refill container of paste and thereafter pump the contents of the container therefrom, whereby the consumer, having purchased one based pump, is saved the cost of purchasing successive new pumps and is required only to purchase a refill container of paste, much as in the case of the system used in the home razor blade market, wherein once the consumer buys the razor holder, he or she need thereafter only purchase the refill blades.
  • Another key objective of this invention is to provide a "bottom heavy" pump which, in contrast to current paste pumps, maintains the material to be dispensed at the bottom of the container, thereby maintaining a low center of gravity so that the pump does not tip over.
  • Current pumps draw the material to be dispensed upwardly, so that the center of gravity increasingly rises to the top of the pump, whereby the pump becomes top-heavy and tips over easily.
  • a further objective of this invention is to provide a refill container for hand-held dispensing devices, especially devices of the type of the presention invention relating to pumps for pastes.
  • Figure 1 shows a hand-held paste pump 11 having a turret-type nozzle or spout 13 at the top thereof.
  • the nozzle includes a ball 12 rotatably seated within a housing 12a.
  • Nozzle 13 has a spout portion connected to ball 12 movable therewith and includes a channel 13a terminating in a dispensing spout 13b.
  • Channel 13a extends through ball 12 and terminates in a material receiving opening 13c.
  • Housing 12a is fitted to--and may be an integral part of--a container body 15 which has a base 16, the latter having a base cover 16a.
  • a piston 17 Disposed within container body 15 is a piston 17 with flexible side seals 18 which is vertically movable in the body 15.
  • a tube 20 which has an upper opening 20a, extends through piston 17 and has a lower opening 20c.
  • a compression spring 19, which may be helical, between the upper interior surface o body portion 12b and the top of piston 17, whereby spring 19 continuously exerts downward force on piston 17.
  • Paste (or other previously mentioned viscous mater) M is loaded into the body of the pump below piston 17 and above bottom 16a. As shown in Figure 1, material M is blocked from movement beyond the opening 20a of tube 20 by the surface of ball 12, but it will be observed tube 20 has been filled with paste by the downward pressure of piston 17 under force of spring 19 up through opening 20c in the tube 20.
  • Figure 2 shows the tube of Figure 1 with the turret nozzle 13 in the open position, i.e., the user has rotated the nozzle to the left in Figure 1 so that opening 13c of the tube channel is in registry with the opening 20a of dip tube 20, whereby the contents of the tube, M, are flowing continuously from nozzle 13b as indicated by the arrow.
  • the embodiment illustrated in Figures 1 and 2 is remarkably uncomplicated and, in fact, comprises only five elements: A body, a nozzle, a piston, a dip tube and a spring (or othere functionally equivalent means of exerting force), all of which have the further advantage of being easy to mold and to assemble.
  • the pump currently on the market sold under the Trademark "Crest" for tartar control paste has at least eight elements and represents an extremely complicated design which, presumably, is difficult to mold and assemble, and therefore relatively expensive.
  • prior art pumps are of the draw-up variety have a piston which moves upwardly within the pump housing to dispense the paste, so that the pump becomes increasingly top-heavy and therefore more likely to fall over. Sometimes this is merely an annoying inconvenience, but in the event the pump falls from, say, a bathroom sink onto a tile or other hard bathroom floor, the pump can be damaged.
  • paste pumps according to the present invention are very easy to fill with paste on a high-speed assembly line.
  • pumps made in accordance with the present invention can be modified to be re-fillable, thereby even further increasing the cost-savings to the consumer.
  • FIG. 3 and 4 One embodiment of a re-fillable pump is shown in in Figures 3 and 4 wherein parts identical or functionally equivalent to those shown in Figures 1 and 2 are marked with a prime, so that it is unecessary to specifically reiterate them here.
  • the body wall 15′ preferably cylindrical in cross-section, terminates in an edge 15a′ which defines an opening 15′b. Inserted into this opening is a refill container 22 with paste M already loaded therein. (Although not shown, it will be understood that container 22, as sold, will have a suitable cover which the consumer removes just before inserting container 22 within the pump 11′.)
  • Refill container 22 is inserted within pump 10′ by threading it into the wall 15′.
  • wall 15′ has screw threads 26 on its inner surface adjacent bottom edge 15a and container 22 has matching threads 25 on its outer surface.
  • the flared top portion 24 of the container 22 forms a tight seal against the inner surface of wall 15′ above piston 17′.
  • the bottom surface 23c of container 22 preferably fits against the lower edge 15a′ of the pump wall 15, thereby enhancing the seal provided by threads 25, 26 to provide a sealed compartment for the material M.
  • the refill has feet 23a and 23b to provide a base for maintaining the assembly in an upright position.
  • Figure 3 shows the refillable pump with its dispensing nozzle 13′ in the closed position
  • Figure 4 shows such nozzle in the open position with the material M being discharged as indicated by the arrow.
  • the pump of Figures 3 and 4 have the great benefit of being capable of utilizing refills, at substantial savings to the consumers.
  • FIG. 5 Another embodiment of a refillable container according to this invention is illustrated in Figure 5 wherein the basic pump body 11 ⁇ does not have an a long body wall extending down the length of the container, but instead comprises what might be termed a head block 28 terminating in a lower edge 29. Just above the line of termination 29 the body 28 is provided with external threads 33. The latter are for the purpose of receiving a refill 27 which has a body wall 30 and threads 32 on the inner wall at the top which engage threads 33 of the body 28.
  • Refill 27 has a closed bottom end 31 and, as packaged for retail sale, will have its open top end closed by a cap, foil or other suitable cover which will protect the contents M and which may be easily removed just prior to attachment as described above.
  • the refill container, 27 in Figure 5 offers great advantages.
  • the consumer need only purchase the pump mechanism once and, thereafter, simply purchase the reill 27, thus saving the cost of buying an entire new pump on each occasion.
  • FIG. 6 illustrates a pump 11′′′ which is similar in construction to pump 10 of Figure 1.
  • pump 10′′′ has an open bottom end equipped with external threads 43. These are designed to engage threads 44 on the inner surface of a lip 42a of a removable bottom cover 42.
  • the purpose of this configuration is to permit the cover to be removed and the insertion of a refill 40, preferably a cylinder, containing paste M.
  • Refill cylinder 40 has a closed bottom 45 and terminates in an open top end 41.
  • the invention of Figure 6 offers similar substantial advantages in cost and product safety to both the consumer and manufacturer. Indeed, the refill 40 can be easily slided into the interior housing of pump 10′′′, and be ready for instant use by attaching cover 42.
  • the refills may take a number of different forms and comprise not only a refill container per se, but, if desired, may include a new piston, such as the piston 17 ⁇ in Figure 5, in which case the original piston will be discarded.
  • the refills may be made of a wide variety of suitable materials.
  • currently sold toothpaste pumps employ polypropylene (PP) or polyethlene (PE) or polyethylene terephlate (PET) or copolymers of PP and PE for the body walls of the pump which contains the paste and these body walls typically are relatively thick in order to prevent loss of flavorants, etc. through the body wall, which can occur when long shelf-life is required.
  • the refills shown herein can be made relatively thin and of said current materials, where long shelf-life is not needed.
  • the refill may be made relatively thin and utilize so-called gas barrier materials, such as ethylene alcohol copolymer (EVOH), polyamides such as Nylon (PA), poyvinyildine chloride and copolymers thereof (PC), etc., which prevent the escape of flavorants or other components of the paste which can convert into a gas phase.
  • gas barrier materials such as ethylene alcohol copolymer (EVOH), polyamides such as Nylon (PA), poyvinyildine chloride and copolymers thereof (PC), etc.
  • EVOH ethylene alcohol copolymer
  • PA polyamides
  • PC poyvinyildine chloride and copolymers thereof
  • These materials may be formed in a single layer, such as by extruding the same as a tube or by extrusion blow molding (EBM), the latter being more desirable since the bottom of the refill is formed in the mold, as well as the threads
  • the particular means whereby the refill container is attached to the pump or inserted theren is, to some degree, a matter of choice.
  • the pump body may be other than circular in cross-section.
  • the body can just as well be square or rectangular in cross-section, in which case the re-fill would have the same cross-section and means other than screw threads would normally be employed.
