Definitions

  • This invention relates to an assembly for the automatic or semi-automatic production of a beverage, primarily but not necessarily, a coffee beverage wherein water or applicable liquid is directed under pressure successively into contact with a plurality of pre-formed packets of powder, granulated or like material which forms the beverage when saturated with water.
  • Such an intended device should be structured to produce or prepare a coffee beverage preferably from a preformed packet having a high quality normally associated with more conventional equipment.
  • such a device should be relatively inexpensive, easy to maintain and operate and include sufficient structural integrity to have a long operable life.
  • the present invention relates to an automatic or at least semi-automatic coffee or like beverage making machine which is designed to form the preferred beverage from a plurality of preformed packets. More specifically, each of the packets are designed to produce one "serving" wherein the size of the packet and the amount of water or other applicable liquid fed to the packet and allowed to pass therethrough will determine the quantity of each serving.
  • a housing includes a first rotatable plate defining a packet carrying member mounted thereon.
  • a second plate is structured to hold a plurality of containers in aligned relation with each of a plurality of packets maintained on the packet carrying member or plate.
  • a first plurality of pockets are formed in the first packet carrying plate and each of the pockets are configured and dimensioned to removably hold a packet therein. Also, these pockets are structured to allow water to pass through the packet and the pocket into an aligned container.
  • a delivery head is reciprocally mounted to engage each of the packets successively as they are rotated into aligned position therewith. The reciprocal movement of the delivery head allows it to be moved into and out of an engaging, compressing relation with each of the successively disposed and aligned packets as they each pass beneath the delivery head.
  • a supply of water or like liquid is forced primarily by a pump means from a conventional liquid or water supply to the delivery head and through each of the packets by a fluid delivery means.
  • a fluid delivery means may include a conduit means to specifically direct water from the liquid supply, under pressure of the pump means, to the delivery head and more specifically to a plurality of integrally formed channels within the head. These channels are disposed to equally disperse the liquid passing through the delivery head into the packets.
  • the water passes through the individual packets, saturating the contents thereof, through the pockets in which they are formed.
  • the formed beverage then passes into the aligned containers located immediately below and in fluid receiving relation to each of the packets.
  • a first drive means serves to synchronize reciprocal movement of the delivery head into and out of the aforementioned engaging position with each of the packets so that the water adequately flows through each packet allowing the beverage to be formed by saturating the contents of the packets.
  • the fluid delivery means further includes a valve means which serves to regulate liquid or fluid flow from the liquid supply, under pressure of the pump means, to the delivery head.
  • the delivery head is maintained in its engaging or compressed position relative to the packet so as to remove any excess water and/or steam, fluid, moisture, etc. from the packet after the vast majority of the liquid passes therethrough into the aligned container. This is accomplished by moving the aforementioned regulating valve to an open position allowing removal of any of the excess moisture or drain fluid from the packets.
  • the conduit means associated with the fluid delivery means serves to remove this drain fluid from the delivery head to a drain or collection facility.
  • Heating means is provided preferably at two locations on the housing.
  • a first heating means is located in direct heat transferring and conducting relation to the delivery head which is preferably formed of a substantially solid, one piece construction of heat conducting material such as metal.
  • a second heating means is located downstream of the pump means and input of the liquid supply such that this liquid is effectively "preheated” by passing through a circuitous route in heat receiving relation to a second heating means.
  • the preheated water then passes through the aforementioned conduit means and the regulating valve structure to the delivery head where it is again heated by the first heating means to insure that the water is at the proper temperature as it passes through and saturates the granulated supply of dry material maintained in the preformed packets.
  • An important feature of the present invention is the existence of a control means which allows the user of the subject assembly to form any number of cups or containers of coffee or like beverage automatically just by applying, through any type of conventional digital control or applicable structure the required or desired number of containers.
  • the packet carrying member or plate as well as the container carrying member located immediately beneath such packet plate is preferably designed to have a capacity to removably support eight packets and eight aligned containers for receiving the beverage to be formed.
  • the user can select the formation of any lesser number of containers or quantity to be formed in the same automatic fashion.
  • a control means more importantly includes a switching means and a timing means which serve to regulate the reciprocal position of the delivery head into its engaging position with each of the packets successively and the amount of "downtime" during which the delivery head will be maintained in such engaging position.
  • Such time must be sufficient to allow the correct amount of water to pass from the pump means through the delivery head and therefrom through each of the packets to form the desired beverage.
  • the downtime must be sufficient to allow the removal of any waste fluid such as steam, moisture, water, etc. from the packet, as set forth above.
  • the timing and control means are cooperatively structured and interconnected to activate the feeding of water to the delivery head at the proper time and in the proper quantities.

  • the subject assembly comprises a housing generally indicated as 10 having a facing control panel 12 with any type of applicable digital or other conventional controls as at 13 in the form of push buttons or the like for the determination of the number of containers of coffee to be "automatically” prepared.
  • the control panel or facing panel 12 as well as the operable components 13 serve to activate a control means generally indicated as 14, to be described in greater detail hereinafter specifically with reference to the operation of the subject assembly.
  • the control means does include a timer means and a switching means preferably in the form of a plurality of micro switches which are activated upon certain movement of the components of the subject assembly which in turn activate the timer and control the various operations of the machine, again to be described in greater detail hereinafter.
  • the subject assembly is designed to form a liquid beverage into individual servings and deliver such servings into individual containers as at 18.
  • a plurality of preformed packets 20 hold the material for making the liquid beverage in granulated, powdered or like form as at 22.
  • the saturation of the material 22 with water or any other applicable liquid serves to form the coffee- type beverage wherein the coffee beverage is eventually delivered to the individual containers 18. Therefore, in the operation of the subject assembly, a packet carrying member 24 in the form of a rotatable plate 26 is rotatably mounted on the housing.
  • a container carrying member in the form of a plate 28 is also rotatably mounted on the housing 10 in synchronization with the plate 26.

  • the first plurality of pockets are shown in somewhat greater detail, individually, in Figure 9 and indicated as 30.
  • Each of the pockets has a hollow interior configuration with an open end as at 32 substantially in the form of a funnel so as to direct the liquid beverage formed directly into one of the containers 18 located immediately below the pockets as shown in Figures 2 and 3.
  • each of the pockets are designed to removably receive and maintain therein one of the beverage forming material preformed packets 20 (see Figs. 18, 19 and 20).
  • Features of the pockets 30 may include an outer ring-type seal as at 33 which serves to cooperate with a delivery head generally indicated as 34 to be explained in greater detail hereinafter.
  • each of the containers 18 are located immediately beneath and in fluid receiving relation to one of the first plurality of pockets 30 and more specifically are positioned to receive formed beverage from the funnel ⁇ like exit or open end 32 of each of such pockets.
  • the containers 18 are maintained on the container carrying member 29 or plate by a second plurality of pockets formed therein for purposes of retaining the containers as shown in Figures 2 and 3.
  • the individual preformed packets 20 are delivered independently and successively to each of the pockets 30 by means of a delivery shoot or sleeve as at 36. Therefore, the delivery shoot 36 can hold a plurality of such packets 20 in a stack-like configuration as best shown in Figure 10. Regulation of delivery in the preferred, predetermined manner can readily occur as the pockets 32 pass beneath and in receiving relation to the supply shoot or sleeve 36.
  • coffee 20 is of course contained therein in granulated form and a lid 20' is sufficiently porous to allow water under relatively high pressure and temperature to be forced therethrough.
  • the material from which the packet is formed is a high tech plastic moldable material which is sufficiently porous to allow the water to pass therethrough.
  • the lid portion 20' is connected to the remainder of the packet 20 by heat welding along all connecting seams and/or junction lines in order to further add to the structural integrity of the packet so that it may withstand the pressures exerted thereon during the compression of the packet when the water flows therethrough.
  • an important feature of the present invention is the provision of a reciprocally mounted delivery head 34.
  • This delivery head forms part of a fluid delivery means to accomplish the delivery of liquid to each of the packets for saturation thereof and while the packets 20 are in their individual pockets 30 in order that the delivered liquid passes through the packets 20 and into the individual aligned containers 18.
  • the delivery head includes a plurality of integrally formed internal channels each interconnected as at 40 with received liquid from a conduit means 42 such that liquid passes through the interior of the delivery head 34 and outwardly from a bottom exposed end thereof as at 42 into an exposed face 20' of the packet and into the interior thereof for saturation of the material 22.
  • Each of the packets are formed of a material which allows the liquid to readily pass therethrough when saturating the contents 22.
  • a strainer or filter-type mechanism as at 44 may fit over the exposed delivery end 42 of the delivery head 34 so as to filter out any type of debris or unwanted substance from contact with the exposed face 20' of each of the packets.
  • the fluid delivery means further comprises a flow regulating valve assembly 48 connected to the conduit means 42 and serving to regulate fluid flow along a conduit section 49 from a supply of liquid, which may be conventional, as at 50.
  • a liquid pump 52 serves to force liquid flow along the conduit means 42 and particularly conduit section 49 passed the regulating valve 48 and to and through the delivery head 34.
  • the delivery head 34 has a first heater assembly maintained in heat transferring relation to an outer surface portion thereof as at 35.
  • Such heater element is a strip-type heater maintained by a tension belt or the like 52 connected in surrounding relation about the outer surface and concentrically thereto by means of a connector assembly 53 attached to the retaining belt 52.
  • Electrical conductors as at 56 are supplied to provide electrical power to the strip-type heater located beneath the retaining belt 52 and in direct heat transferring relation to the outer surface of the portion 35 of the delivery head 34.
  • the delivery head 34 is made from a heat conducting material such as metal and due to its integral and/or one piece construction serves to heat the water passing through the individual channels 40.
  • a second heating assembly is located as at 58 (see Fig. 5) .
  • This "preheater” is provided to initially heat the water as it is forced by pump 52 and as it enters the housing 10 through the inlet from the liquid supply as at 50.
  • the conduit means 42 and particularly conduit section 49 is connected to deliver the preheated water from the second heater means 58 directly to the delivery head 34.
  • a first drive means 59 includes drive motor 61 and provides the reciprocal movement of the delivery head 34 into and out of confronting, engaging and somewhat compressing relation to the individual packets 20 as they are aligned immediately beneath the delivery head 34 due to synchronized and predetermined rotation of the packet carrying member 26.
  • the first drive means includes a rotating cam 60 engaging a roller type cam rider 62 which is connected to a support frame 64.
  • the delivery head 34 is mounted by connectors 66 such as bolts directly int internally threaded receiving apertures 66* such that reciprocal movement of the frame 64 due to interengagement of the cam rider 62 with the periphery of the rotating cam will cause a reciprocal vertical positioning of the delivery head 34 into and out of what may be referred to as an engaging position.
  • Such engaging position is clearly demonstrated in Figures 8 and 18 through 20.
  • biasing springs 68 are amounted so as to normally bias the support frame 64 and the attached cam rider 62 into a non-engaging position where the delivery head 34 is spaced upwardly from the packet 20 and/or packet carrying member or plate 26.
  • the delivery head 34 upon rotation of the cam member into its "downstroke” the delivery head 34 will be forced into the aforementioned engaging position such that its exposed face 42 (see Fig. 12) engages the exposed outer surface or portion 20' and provides a certain amount of compression thereon.
  • the actual determination of when the delivery head 34 passes into its engaging position as shown in Figure 8 from its non- engaging position as shown in Figure 7 is determined by the control means which, as set forth above, includes certain micro switches and timer assemblies.
  • the length of the time that the delivery head 34 is in the aforementioned engaging position is also determined by such control means all of which will be explained in greater detail hereinafter.
  • a second drive means is indicated as at 70 and serves to drive a drive pulley 72 connected to a driven pulley 74 by an interconnecting drive belt 76.
  • Activation of the drive motor 70 serves to rotate, in synchronization, both the rotatable plates 26 and 28 carrying the packets 20 and the containers 18 respectively. Both are driven in the synchronized fashion set forth by virtue of an interconnection through a rotatable connecting shaft as at 78. Therefore, it should be evident that the delivery head 34 is periodically reciprocated downwardly into its engaging position as shown in Figures 18 through 20 during which time water is delivered to the packets 20 for saturation of the material 22 (see Fig. 19) wherein the water passes through the packets 20, material 22 and out through the bottom of the pockets 30 by means of a nozzle-like structure 32.
  • the delivery head 34 is maintained in its downwardly engaging position so as to effectively remove any excess moisture, steam or the like and pass it through conduit section 49" conduit means 42 down to a drain or collection facility 79 as shown in Figures 2, 4 and 5.
  • the delivery head is then moved up to its non-engaging position (see Fig. 7) upon the rotation of the cam 60 of the first drive means 59 after sufficient time has elapsed which has been pre-set and regulated by the control means generally indicated as 14.
  • the regulating valve 48 (see Figs. 19 and 20) may be in the form of a solenoid operated valve and is moved to its open position to close the conduit segment 49 and open the conduit segment 49" allowing the retrieved and waste moisture or steam-like fluid to pass through conduit means 42 and through the conduit section 49" into the drain or collection facility 70 (see Figs. 2, 4 and 5).
  • the aforementioned control means through the provided timer means and switching means serves to regulate the amount of liquid flow passing from the liquid inlet 50 through the controlled activation or operation of the pump means 52. Therefore, the time of liquid flow from the supply inlet 50 to the delivery head and therefrom into the individual packets 20 is regulated as well as the amount of liquid flowing thereto.
  • the control means includes a timing means and a switching means. These in turn are defined by a first micro switch structure 80 powered by a conventional power source through a conductor 82 and carried on the support frame 64 so as to reciprocate with the delivery head 34.
  • An activating button 84 serves to trick the micro switch 80 which in turn controls a first timer means.
  • the first timer means in turn regulates the activation of the drive motor 61 and determines the instigation of the downward stroke of the delivery head 30 and how much time the delivery head 30 is maintained in the engaging position as shown in Figures 19 and 20. Such time must be sufficient to allow the delivery of liquid through the activation of the pump means 52 from the liquid supply 50 into and through the delivery head 34. Further, such time must be sufficient to allow the withdrawal of any waste fluid as explained with regard to Figure 20.
