Definitions
- the present invention relates to a form, fill and seal packaging machine for gable top cartons. More specifically, the present invention relates to a packaging machine capable of sterilizing spout before application to a carton.
- Such packages are generally comprised of a blank made from a paperboard substrate that is sandwiched between layers of a thermoplastic material. These blanks are side-sealed and presented to the input of a packaging machine. The packaging machine erects these blanks, seals their bottoms, charges them with product, and seals their tops.
- a number of such package-types have now come into common use.
- One such package type is the gable-top container.
- Another such package type is the brick-type container.
- it has become popular to provide such containers with a spout assembly comprising a fitment and a cap that provides the container with a resealable opening that provides quick and simple access to the container contents.
- a packaging machine that is designed to form and seal a package with such a spout assembly is set forth in U.S. Patent No. 4,788.811, entitled "Process and Apparatus for Assembling and Liquor-Charging of Packages of Paper and the Like".
- the device disclosed in the '811 patent purports to be an apparatus for the successive production of a number of paper packages fitted with respective spout on a part of the top end portion thereof and charged with a liquid drink.
- the spout includes a spout proper having a general cylindrical are configuration and formed generally therethrough with a liquid spouting passage provisionally fixed to the root end of the spout proper.
- the spout is introduced into the open end of a semi-package from inside thereof.
- the spout introduction and attaching job is carried out directly before charging with liquid. Only thereafter, liquid charging-in and top-closing jobs are carried out in a sterilized atmosphere. Within the sanitary execution of these jobs, the spout agency and sealing attachment are included for increasing the sanitary safety.
- the spout assembly comprises a cap disposed on a fitment and may be functionally divided between an interior portion for disposition toward the interior of the container and an exterior portion for disposition toward the exterior of the container.
- the apparatus comprised a storage bin for storing a plurality of the spout assemblies and a guide assembly for guiding the plurality of spout assemblies to present them individually at an output of the guide assembly.
- a fitment and cap sterilizer accepts individual ones of the plurality of spout assemblies from the output of the guide assembly and applies a disinfecting solution to their respective interior portions.
- An output guide assembly accepts the individual ones of the spout assemblies after they have had their interior portions disinfected and guides them to a subsequent processing station.
- the subsequent processing station may, for example, be a spout applicator that applies the spout assembly to the container.
- An intermediate UV station may be used between the fitment and cap sterilizer and the spout applicator to further sterilize the spout assemblies prior to application.
- the fitment and cap sterilizer comprises a track for supporting and guiding a plurality of the spout assemblies along a predetermined path.
- a gate mechanism is disposed to interrupt movement of the plurality of spout assemblies along the track.
- the gate assembly is operable to selectively retain individual ones of the spout assemblies at a predetermined position along the track and selectively pass the retained spout assembly for further travel along the track.
- a sprayer is disposed in fixed alignment with a spout assembly that has been retained at the predetermined position by the gate assembly for spraying the retained spout assembly with a disinfecting solution.
- FIG. 1 is a diagrammatic view of a spout application station and container sterilization station of a packaging machine in accordance with one embodiment of the present invention.
- FIG. 2 is a view of a cross-section of a spout assembly that has been applied to a container wherein the container is undergoing a post-application sterilization process.
- FIGs. 3 - 5 are various views of a fitment and cap sterilizer constructed in accordance with one embodiment of the present invention.
- FIG. 6 is a perspective view of one embodiment of a track assembly for use in the present invention.
- FIG. 7 is an end view of the track assembly illustrated in FIG. 6.
- FIG. 1 One embodiment of an apparatus for providing a container, such as a gable- top container, having a spout assembly disposed thereon is set forth generally at 10 of FIG. 1.
- a plurality of containers 15 are transported between successive processing stations in the direction indicated by arrow 20 by, for example, an endless belt conveyor (not illustrated). Two such processing stations are illustrated here.
- a first processing station 25 is provided to attach a spout assembly to each of the containers 15.
- the spout assemblies are sterilized prior to such attachment thereby providing a more sterile packaging process that gives rise to a naturally extended shelf life for the product.
- a second processing station 30 is provided to sterilize the interior portions of the containers 15.
- the first processing station 25 comprised a spout assembly storage bin 35 that is used to store a plurality of spout assemblies.
- the storage bin 35 comprises an outlet 40 attached to the input of a length of spout assembly track 45.
- the spout assembly track 45 extends between the storage bin 35 and the input of a fitment and cap sterilizer 50 and facilitates transport of spout assemblies therebetween.
- the spout assemblies are transported along the track 45 using gravity and, if necessary, bursts of sterile air or the like.
- the fitment and cap sterilizer 50 functions as a disinfecting assembly that accepts individual ones of that are serially transported along the track 45. Disinfection proceeds by applying a disinfecting solution, such as hydrogen peroxide, to the spout assemblies.
- a disinfecting solution such as hydrogen peroxide
- each spout assembly 55 may be functionally comprised of two sections: an exterior section 60 that, upon application to the respective container 15 is disposed toward the exterior of the container and, further, an interior section 65 that, upon application to the respective container, is disposed toward the interior of the container 15.
- sterilization of the interior sections of the spout assemblies is neglected in that the interior sections are difficult to access once the spout assemblies have been attached to the respective container.
- a dispersion of hydrogen peroxide illustrated here with arrows 70 fails to reach certain interior portions of the spout assembly 55.
- Such regions effectively become “shadowed” regions that do not receive an application of hydrogen peroxide.
- post-attachment container sterilization frequently leaves substantial portions of the spout assembly 55 in a septic state that can contaminate the container contents and, thereby, lowers the effective shelf life.
- each spout assembly is subsequently provided to an optional ultraviolet station 80.
- the ultraviolet station 80 irradiates each spout assembly, particularly the interior portion thereof, as it passes therethrough. Such irradiation, particularly when combined with an application of hydrogen peroxide as the disinfecting solution, provides for a very effective sterilization of the spout assembly.
- each spout assembly is guided along track 85 to a spout applicator 90 that applies the spout assembly to the respective container 15.
- the spout applicator 90 can take on any number of forms.
- the spout applicator 90 may be an EL-64 such as available from Cambridge Valley Machining. Other spout applicators are likewise suitable for such use.
- the station 25 may be maintained in a generally sterile environment. Accordingly, the station 25 may be provided with a circulation of sterile air. Additionally, or in the alternative, the station, or portions thereof, may be surrounded by sidewalls defining a sterile chamber or the like.
- the container and spout assembly are transported in the direction of arrow 20 by, for example, a chain conveyor or the like, to the further sterilization station 30.
- the container 15 undergoes a sterilization process that, for example, includes an application of hydrogen peroxide followed by irradiation with ultraviolet light.
- the containers 15 After undergoing the sterilization process at sterilization station 30, the containers 15 are conveyed to subsequent processing stations (not illustrated ) where they are charged with product and top-sealed. Such charging and sealing operations are not particularly pertinent to the present invention and, for example, may be carried out using conventional processes.
- FIGs. 3 - 5 illustrate one embodiment of a fitment and cap sterilizer 50 that may be used in the station 25.
- the spout assemblies 55 are conveyed along a predetermined path that this defined by a track 100 of the fitment and cap sterilizer 50.
- a gate mechanism shown generally at 110, is disposed to interrupt movement of the spout assemblies 55 along the track 100. More particularly, the gate mechanism 110 is operable to selectively retain individual ones of the spout assemblies 55 at a predetermined position along the track 100 while a spray mechanism, shown generally at 120 sprays the interior portion of each spout assembly 55 with a disinfecting solution, such as hydrogen peroxide.
- a disinfecting solution such as hydrogen peroxide.
- the particular embodiment of the gate mechanism 110 utilizes a circular gate 125 having a cutout portion 130.
- the cutout portion 130 corresponds to the shape of the cap portion 135 of an individual spout assembly 55 and engages a peripheral portion thereof.
- the circular gate 125 is disposed to interrupt travel of the spout assemblies 55 along the track 100.
- the gate 125 is rotated by an actuator 150 in response to control signals received at one or more inputs 152.
- the actuator 150 rotates the gate 125 between a first position in which the gate 125 engages and retains an individual spout assembly 55 in the cutout portion 130 at a predetermined position and a second position in which the gate 125 passes the retained, individual spout assembly 55 to an outlet portion 160 of the track 100.
- the rearward portion 165 of the circular gate 125 engages a subsequent one of the spout assemblies 55 thereby preventing further spout assemblies from passing through the fitment and cap sterilizing station 50.
- each spout assembly 55 undergoes its own individual sterilizing process.
- the actuator 150 of the disclosed embodiment is responsive to a pneumatic control signal at inputs 152, it will be recognized that other actuators responsive to other types of actuating signals may also be used.
- the spray mechanism 120 is disposed opposite the gate mechanism 110. Although the spray mechanism 120 and gate mechanism 110 are illustrated in a vertical orientation, it will be recognized that a horizontal orientation is preferable if gravity is to be used to convey the spout assemblies along the track.
- the spray mechanism 120 comprises a body portion 170 and a nozzle portion 175.
- the body portion 170 includes a first inlet 180 for receiving sterile atomizing air or the like.
