Definitions

  • the invention relates to a dispensing device according to the preamble of claim 1 (FR-A-2 546 483).
  • 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.
  • FR-A-2 546 483 discloses a dispensing device according to the preamble of claim 1.
  • Two ball check valves allow the flow of pasty material from the interior of a housing through a central tube into an intermediate chamber upon a first downstroke of the dispensing head. Upon a second downstroke the material stored in the intermediate chamber will be dispensed through a nozzle.
  • US-A-3,907,174 discloses a dispensing pump to be used with small hand held containers for cosmetic and like products.
  • the pump includes a nozzle which is foldable from a horizontal, discharge position to a vertical, storage position.
  • the object of the invention is to provide for an improved dispensing device for pasty material, said device being of a simpler design than the prior art devices.
  • a dispensing device particularly adapted to dispense pasty materials
  • a container body containing said pasty material
  • a bottom surface closing one end of said container body said other end having a nozzle connected to a rotatable ball valve seated within the other end, said nozzle having a channel therethrough
  • a tube extends from said other end of said container body to adjacent said one end
  • a piston is disposed within said container body and encircling said tube, the piston being vertically movable in said container body
  • a compression spring means is disposed between said other end and said piston with pasty material disposed between said piston and said one end, the spring means continuously exerting a force on said piston
  • an opening of said channel is rotatably movable into and out of alignment with said tube so that said pasty material can be dispensed from said container body.
  • Fidure 1 illustrates one embodiment of the pump device of this invention in vertical cross-section in the fully loaded condition.
  • Figure 2 illustrates another cross-sectional view of the device of this invention shown in Figure 1 but with the contents partially emptied and the turret nozzle in the open position.
  • Figure 3 is a vertical cross-section of another embodiment of this invention illustrating a refillable pump wherein the turret nozzle is in the closed position and the refill has just been fitted into the pump in a full condition.
  • Figure 4 is another cross-section of the pump of Figure 3 in partially emptied loaded condition after the insertion of a refill container, and with the nozzle in the open position discharging the contents of the tube.
  • Figure 5 is another embodiment of the combination pump/refill device of the present invention in vertical cross-section.
  • Figure 6 is yet another embodiment of this invention taken in vertical cross-section.
  • 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 of the body portion 12b and the top of piston 17, whereby the spring 19 continuously exerts a 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 15b′. 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 (PA) such as Nylon, polyvinyildine chloride and copolymers thereof (PVDC), 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 (PA) such as Nylon, polyvinyildine chloride and copolymers thereof (PVDC), etc.
  • EVOH ethylene alcohol copolymer
  • PA polyamides
  • PVDC polyvinyildine 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
  • refill containers having different designs may be used.
  • 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.
