Definitions
- ABSTRACT A form-fill-seal type of packaging machine in which a pair of rolls of plastic are used in respectively forming and sealing containers is provided with a pair of utilization tanks through which the two webs of plastic material are fed in order to sterilize the webs or sheets due to contact with a sterilizing liquid such as hydrogen peroxide contained in the two tanks. Should the machine be shut down either deliberately or by inadvertence for any reason, the germicidal agent may affect the plastic material immersed therein in an adverse manner. Thus means are provided for draining the germicidal liquid from the utilization tanks into a reservoir tank thereby to preclude any possible undesired effects by controlling suitable valves in the supply and return conduits or by other means.
- each tank is supplied from a reservoir through a suitable common pump and through individual supply conduits and supply valves which are normally open and the level of liquid in both tanks is determined by an overflow conduit which drains into the reservoir tank and which is interconnected with its associated utilization tank at a level controlling the desired level of liquid. in such tank.
- the temperature of the liquid preferably should be controlled and maintained at a level above ambient temperature. To this end the liquid is heated and the liquid flow is controlled so that the desired temperature is maintained in the utilization tanks.
- drain conduits and normally closed drain valves are interconnected with the inlet of the pump and the outlet of the pump is connected with the reservoir tank through a return conduit and a normally closed return valve which is opened during the draining operation, so that the pump facilitates draining of the tanks.
- the supply valves are closed while the two tanss are being drained. If desired the utilization tanks can be drainedquickly by simply reversing the flow of liquid by means of a reversible pump.
- FIG. 1 is a generally schematic side view of a form fill seal machine to which the web sterilizing system constructed according to this invention is applicable;
- FIG. 1A is a perspective view of one utilization tank
- FIG. 1B is a perspective view of the other utilization tank
- FIG. 2 is a schematic diagramatic representation of the conduits, tanks, valves and pumps which constitute parts of this invention.
- the numeral 1 generally designates a roll of plastic material which is utilized in forming the body portion of containers such as cups or the like while the numeral 2 generally designates a roll of plastic material which forms the cover portion or lid of cups formed from sheet 1.
- Roll 1 is mounted on a horizontal shaft designated by the numeral 3 which is supported by horizontal frame elements designated by the numeral 4 together with a pair of vertical pedestals designated by the numeral 5, only one horizontal member 4 and one vertical member 5 being visible in FIG. 1.
- a generally arcuate shaped tank 6 is supported on horizontal support elements 4 and is filled with a suitable germicidal liquid such as hydrogen peroxide through which the sheet S1 from roll or web 1 is fed.
- the numeral 7 generally designates heater units under which the sheet S1 is fed, the feeding operation being facilitated and the drying thereof being enhanced by a pair of rollers designated by the numrral 8. If hydrogen peroxide is used as the germicidal agent, its decomposition into water and nascent oxygen and then into oxygen is facilitated by heaters 7. Sheet S1 is fed from heaters 7 and rollers 8 into a forming press generally designated by the numeral 9. This press is provided with relatively movable dies which form a plurality of cups from the sheet S1.
- the cups are formed they are fed while still interconnected across their upper edge portions'by the web of sheet S1 into a filler station generally designated by the numeral 10 where the cups are filled.
- the cups are fed while still under aseptic conditions and enclosed within a suitable housing structure 1 1 into a sealing press generally designated by the numeral 12 where the covers or lids are applied to the cups.
- the cups are severed one from another about their top edges at the cutting station generally designated by the numeral 13.
- the sealed and sev ered individual cups are then complete and are ready for secondary packaging operations if desired by means other than the machine elements depicted schemati cally in FIG. 1.
- the sheet S2 supplied from roll 2 of course must be germ free and toward this end sheet S2 is fed through a utilization tank 14 which is filled with a germicidal liquid such for example as hydrogen peroxide.
- Sheet S2 if fed over rollers 15-20 and past heating elements not shown to the sealing press 12 where it is sealed by known means to the cups formed from sheet S1, roller 17 being immersed within tank 14 which may be configured substantially as shown.
- the web S2 is fed from its outlet in tank 14 thorugh a closed housing (not shown in detail in the drawings) to the sealing press 12 thereby to maintan web 82 under aseptic conditions.
- utilization tanks 6 and 14 are supplied with heated germicidal liquid such as hydrogen peroxide from a reservoir tank such as is designated in FIG. 2 by the letter R and the liquid level in the utilization tanks 6 and 14 is maintained at a desired maximum by means of overflow conduits which are interconnected with the utilization tanks through suitable ports the level of which determines the liquid level within the utilization tanks. Furthermore and in accordance with a feature of this invention, the utilization tanks 6 and 14 are quickly drained by the supply pump P either by means of valve action and drain pipes or by reversing the pump. The liquid may be heated in the reservoir tank by known thermostatically controlled heating elements.
- utilization tank 6 is supplied with liquid by a supply conduit 21 in which supply valve 22 is disposed, this valve being normally open so that during operation of centrifugal pump P, liquid is supplied from tank R through conduit 21, supply valve 22 and manually controlled regulating valve 23 to utilization tank 6.
- the rate of flow of fluid through supply conduit 21 must be such as to maintain the level of liquid in utilization tank 6 at least to the level of outlet ports 24 and 25 formed at oppositely disposed points in utilization tank 6.
- Overflow conduit 26 is interconnected with ports 24 and 25 and as indicated by the arrow conducts excess liquid in utilization tank 6 back to reservoir tank R and in this manner maintains the desired level of liquid in utilization tank 6.
- a drain conduit 27 and a normally closed drain valve 28 are provided and serve to interconnect the inlet 29 of pump P and the utilization tank 6, such connection being made through normally open manually controllable regulating valve 23 and a portion of supply conduit 21 together with a return conduit 3 whih interconnects the outlet 31 of pump P through a normally closed return valve 32 with the reservoir tank R.
- tank 6 is formed of a bottom wall 33 which is arcuate in configuration with the mid-portion 34 thereof bowed downwardly and with the side edges 35 and 36 extending upwardly.
- Top wall 37 is similarly configured and the end edges of walls 33 and 37 are closed by end plates 38 only one of which is observable in FIG. 2.
- Syitable guides not shown preferably are disposed along the inside surface of wall 37 and serve to space web 81 therefrom.
- Tank 6 as shown in FIGS. 1 and 1A is generally J- shaped with the longer prong at outlet edge 36 in closed communication with housing structure 11 thereby to maintain web S1 under aseptic conditions.
- roll 1 is conveniently mounted on horizontal supports 4 and may be disposed partially within the recess defined by the downwardly bowed top wall 37 of tank 6.
- supply conduit 39 interconnects the outlet 31 of pump P with the inlet 40 of utilization tank 14 through normally open supply valve 41 and through normally opened manually controllable regulating valve 42.
- overflow conduit 43 is interconnected with port 44 of utilization tank 14 and with resevoir R as is apparent in FIG. 2.
- Normally closed drain valve 45 is interconnected between supply conduit 39 and overflow conduit 43 via short drain conduit 46.
- receptacles are formed from a first web of packaging material at a forming station, filled with a product at a filling station, and provided with a cover supplied from a second web of packaging material at a sealing station, the system for treating said first and second web of packaging material with sterilizing solution, comprising a. a reservoir tank containing a supply of sterilizing solution,
