Ice bagging machines, ice vending machines, and ice bagging and vending machines are known in the art in general. Many different forms of these machines are in commercial use or are described in the prior art.
U.S. Pat. No. 4,368,608 discloses an automatic ice bagger that freezes a measured amount of water into cubes. The cubes are dropped directly into a bag placed under a chute. The bag is heat sealed, and then released and dropped into a cold storage bin that stores the filled bags.
U.S. Pat. No. 4,689,937 discloses an article bagging unit useful in bagging ice. A bag, positioned to receive ice cubes, is partially opened by an air blower and then fully opened by two pairs of fingers. The bag is filled with ice cubes and heat sealed.
U.S. Pat. No. 4,878,523 discloses an ice measuring and dispensing machine which includes an ice supply hopper, a housing having three measuring and dispensing chambers which continuously rotate about a vertical axis, and a discharge chute. Additionally, a hammering device makes repeated, jarring contact with the wall of the chambers to vibrate the chambers and prevent the collection of ice therein.
U.S. Pat. No. 5,079,897 discloses a device for transferring bags from a volumetric bagger to a bag-closing machine. A fan automatically opens a bag. The required amount of ice is transferred from a hopper to the bag, and then removed to the bag transfer device. The bag transfer device then brings the bag to a bag-closing machine where the bag may be closed by any suitable method, such as stitching or heat sealing.
U.S. Pat. No. 5,109,651 discloses an ice bagger comprising an ice collecting zone, which has a water drain, and an auger positioned below and in communication with the ice collecting zone and in communication with a separated ice delivery and bagging zone. The ice bagging apparatus is combined with an ice making apparatus and a bagged ice storage zone.
U.S. Pat. No. 5,277,016 discloses a method and apparatus for bagging ice cubes produced by a plurality of cubers with only one bagger when the cubers are stacked side-by-side with the ice produced by each cuber falling into one of two hoppers. The ice is moved from each hopper alternately to the bagger. There, each batch of ice cubes is dropped into a bag, sealed, and moved to a bag storage bin positioned below the bagger.
U.S. Pat. No. 5,458,851 discloses an automatic ice bagger with a self-contained sanitizing system. The sanitizing system periodically activates to sanitize the ice hopper. A flow of water is directed to the hopper to melt the ice in the hopper and to flush the melt water to a reservoir.
U.S. Pat. No. 5,581,982 discloses a method for automatically bagging ice using a timer and multipositional electronic scale. Ice is delivered to a bag until a sensor provides a signal indicating that the bag is full. The bag is then sealed, released, and delivered into an ice bag storage bin.
U.S. Pat. No. 5,630,310 discloses an ice bagger comprising an ice maker, an ice bagging unit, which includes an automatic sanitation system, and a merchandiser. The ice maker delivers particulate ice into a hopper housed within the ice bagging unit. The ice bagging unit includes a bag carrier which retrieves a bag from a bag supply and opens the bag underneath a delivery chute communicating with the hopper via an auger. A scale supports the bag during its filling to measure the weight of the ice delivered into the bag from the hopper. A heating element then activates to seal the bag closed.
U.S. Pat. No. 5,708,223 discloses a remote sensing ice merchandiser. Bagged ice is presented to the consumers in an insulated cabinet having a storage chamber accessible through a front door. Photo-electric eyes mounted within the cabinet detect when the level of bagged ice falls within a certain level and transmits this information to an inventory control station.
U.S. Pat. No. 6,112,539 discloses a device for making, bagging, and delivering a heat-sealed bag of ice to a consumer. Ice is supplied to a hopper and then dispensed into a bag, which is then heat-sealed and delivered to the customer.
U.S. Pat. No. 6,266,945 discloses an ice supply system, which includes a dispenser system, an ice bagger system, and an ice transport system for providing a supply of ice. The ice transport system is operatively linked with the dispenser system for transporting ice to the dispenser system and with the ice bagger system for transporting ice to the ice bagger system The ice supply system includes a dispenser system, which preferably includes a dispenser unit for facilitating the dispensing of a desired beverage and accompanying ice. The dispenser unit includes an ice bin for receiving and storing ice received from an ice making system. The ice supply system also includes an automatic ice bagger for providing individual bags of ice to consumers. A vacuum pump is used to induce movement of ice along the ice supply system.
Often, pre-bagged ice bags, whether made offsite and shipped to a retail site or bagged onsite and stored in bagged form, are frozen hard and are days and weeks old before a consumer can obtain them through a dispenser box. Such pre-bagged hard ice is stale and can undesirably take on odors during storage or transport. Also, pre-bagged ice often agglomerates into chunks of ice that are too large for consumers to readily use, e.g., they will no longer fit into a cup or pitcher, which forces the consumer to take additional efforts to reduce the ice agglomerate size before use. Thus, it is desired to provide an apparatus and method whereby a consumer can receive fresh-bagged ice conveniently, at any time of the day or night. It is also desired that the source of ice be made onsite to avoid the cost, expense, and time-lag of transporting pre-bagged ice to a retail site where consumers may purchase it.
The invention relates to an automated fresh-ice vending apparatus that includes a holding vessel configured and dimensioned to contain sufficient freshly formed ice pieces to provide a replenishing supply in situ for an indeterminate time, and an ice transferring device positioned in the holding vessel and configured and adapted to transport a portion of the fresh ice pieces in a substantially horizontal direction to remove the portion through an aperture of the holding vessel to a weighing device, whereby the weighing device meters out a portion of fresh ice pieces and deposits the portion into a readily transportable container.
In a preferred embodiment, the apparatus is configured and adapted to transfer older ice pieces through the aperture to minimize or avoid ice staleness. In another preferred embodiment, the apparatus provides fresh ice pieces while minimizing or avoiding ice agglomerates that form when ice pieces reside adjacent each other for a sufficient time period. In yet another preferred embodiment, the substantially horizontal direction includes movement of the ice pieces across a portion of the holding vessel to the aperture at an angle of no more than about 20 degrees from the horizontal. In yet another preferred embodiment, the holding vessel is chilled to maintain the ice pieces at a temperature of lower than about 34° F.
In another embodiment, the apparatus further includes an ice making device including a water source and being operatively associated with the holding vessel so that ice pieces can be automatically produced thereby and disposed in the holding vessel. In a preferred embodiment, the readily transportable containers are fully formed, discrete, plastic bags including an open end that is closed after the metered portion is deposited therein and including a second permanently closed end. In another preferred embodiment, the apparatus further includes a fan that operates to blow open the open end of each bag to facilitate filling of the bag with the metered portion of ice pieces. In yet another preferred embodiment, the apparatus further includes a positioning device configured and adapted to position the bag so the open end can receive the metered portion of ice pieces. In yet a further preferred embodiment, the apparatus further includes a closing device configured and adapted to releasably fasten each open end to seal each bag.
In one embodiment, the apparatus further includes a downwardly angled surface to facilitate delivery of each filled, sealed, readily transportable container to the consumer. In a preferred embodiment, the ice transferring device further includes an upwardly directional ice transport device operatively positioned and configured to receive the portion of ice pieces from a location adjacent the aperture and to transport the portion in an upwards direction to a weighing device. In yet another preferred embodiment, the ice transferring device further includes an ice sweep that begins at a starting position and moves in a substantially horizontal direction to facilitate transfer of the portion of the ice pieces to a position outside the holding vessel.
Another aspect of the invention also encompasses an automated ice vending apparatus including a holding vessel configured and dimensioned to contain sufficient ice pieces to provide a constant supply for an indeterminate time, and an ice transferring device positioned in the holding vessel that includes a transport mechanism at an end of the holding vessel that is inclined and that moves a portion of the ice pieces at the end at an angle including a downwardly vertical direction and a horizontal direction toward an aperture and out of the vessel to remove the portion through the aperture to a weighing device, whereby the weighing device meters out a portion of fresh ice pieces and deposits the portion into a readily transportable container. In a preferred embodiment, the transport mechanism includes a plurality of movable projections disposed transversely to the incline and along the inclined portion thereof to facilitate movement of the ice pieces from the holding vessel through the aperture. Various embodiments described above are also applicable to this aspect of the invention.
The invention further relates to a method for automatically delivering a plurality of pre-weighed ice pieces to a consumer by providing in situ a constant supply as needed of a plurality of loose ice pieces from a water source to a storage zone, holding a sufficient amount of ice pieces in the storage zone to provide a constant supply of loose ice pieces, transporting a plurality of ice pieces out of the storage zone to a weighing zone, weighing a pre-selected portion of the ice pieces, and depositing the pre-selected portion of the ice pieces into a readily transportable container.
In one embodiment, the method further includes opening an end of each readily transportable container to facilitate depositing the portion of ice pieces therein, wherein each container is discrete and separate from other containers and each has a second end that is permanently closed. In a preferred embodiment, the method further includes releasably securing an open end of the discrete, readily transportable container. In yet another preferred embodiment, the releasably securing includes stapling or tying the open end of the discrete container. In a preferred embodiment, the transporting, weighing, and depositing together occur in about 4 to 20 seconds.
Further features and advantages of the invention can be ascertained from the following detailed description that is provided in connection with the drawing(s) described below:
An automated, fresh-bagged ice vending machine has now been invented that advantageously provides an apparatus, fresh-bagged ice, and methods for operating the apparatus that have been long desired in the ice vending art. The present invention advantageously can provide a constant supply of ice pieces over an indeterminate time to consumers by making and bagging ice on-site and on demand by the consumer(s). Such freshly bagged ice tends to minimize or avoid the staleness problems of pre-bagged hard ice, and can minimize or avoid undesirable odors by avoiding lengthy storage or time-consuming transport between the ice manufacturing and the bagging. Another potential benefit of the present invention is that containerized ice can be provided on-site, thereby avoiding the expense of transporting ice pre-bagged at a second location. The ice provided by the apparatus and process of the invention also minimizes agglomerates of ice that are too large for consumers to readily use, e.g., they will no longer fit into a cup or pitcher.
The present invention can accomplish this by providing a holding vessel configured and dimensioned to contain a significant quantity of ice pieces, e.g., greater than about 500 pounds, that provides a constant supply of ice pieces on demand in containerized form over an indeterminate period of time. Preferably, the holding vessel is sized and configured to contain at least about 2,000 pounds of ice pieces to about 20,000 pounds, preferably about 4,000 to 12,000 pounds. Since the apparatus optionally, but preferably, includes an ice making device, preferably an automatic ice making device attached to a water source, ice pieces can be provided in a sufficient quantity to replenish ice pieces that are removed from the holding vessel upon purchase by consumer(s). The automated vending apparatus of the invention can be arranged to provide about 300 to 1000 bags of ice in a 24-hour period, preferably about 400 to 600 bags. These bags are typically either 16 pound or 20 pound sizes. Other suitable container sizes can be selected, as well. In addition to the holding vessel and optional ice making device, the apparatus further includes an ice transferring device operatively associated with the holding vessel that is configured and adapted to transport a portion of the ice pieces in a substantially horizontal direction to remove the portion out of an aperture of the holding vessel. Optionally, but preferably, the apparatus further includes an upwardly directional ice transport device operably positioned and configured to receive the ice pieces from the aperture that can bring the ice pieces from a position adjacent to the aperture upwards to a weighing device 21. The apparatus includes the weighing device 21, which meters out a pre-selected portion of ice pieces and deposits the portion into a readily transportable container for use by the consumer. Preferably, the entire apparatus operates automatically with human intervention arising only when the consumer provides payment to the vending apparatus to initiate the bagging of the pre-selected portion of ice pieces in the paid-for amount, and as needed to refill a supply of empty containers that are stored as part of the apparatus into which ice pieces are disposed during operation.
To facilitate the automation of the inventive apparatus, a programmable logic control (“PLC”) can be used to control a portion or all of the apparatus, including the initiation, duration of operation, and termination of each operation. For example, the PLC can instruct the motors that supply the power for the moving parts of the apparatus when to start and stop, and for how long to run. The payment system of the apparatus is operatively associated with the PLC, as are various limit switches or other input devices that provide input to the PLC so it can determine when sufficient ice has been transported to any given part of the apparatus.
Referring to
The holding vessel 2 must be sufficiently insulated to retain a majority of the ice in solid form so as to minimize or avoid substantial melting of the ice. The holding vessel 2 is preferably insulated from the environment by insulation chamber 210. While some loss of ice in the form of melt runoff can generally occur, and the apparatus preferably is operatively associated with a drain to channel the runoff away from the ice, it is more economical to retain as many ice pieces as possible in a frozen state. In a preferred embodiment, the holding vessel 2 is a chilled vessel 2 that includes a refrigeration unit (not shown) to keep the temperature in the vessel 2 below about 38° F., preferably below about 36° F., and more preferably below about 34° F. In a more preferred embodiment, the chilled vessel 2 includes a suitable freezer device (not shown) to maintain a temperature of no greater than about 32° F.
Preferably, sufficient ice pieces are already present in the holding vessel 2 when payment is validated. The ice maker 1 can be operatively linked to an ice demand system (not shown) of any type that suitably detects when additional ice pieces are required in the holding vessel 2 and triggers the ice maker 1 to produce more ice pieces. The ice maker 1 is preferably located outside of the insulation chamber 210 to minimize the amount of space required to be insulated, and to inhibit freezing of the ice maker components or the water therein being used to make ice. The ice demand system can simply make sufficient ice to replenish the amount purchased, thereby returning the ice quantity in the holding vessel 2 to an original level. Alternatively, the ice demand system can be arranged to initiate ice maker 1 at the time of payment to make ice to replenish the amount paid for or delivered. Preferably, an ice quantity detector, such as an optical-electronic system, can be disposed above or at the top of the holding vessel 2 or embedded within the sides thereof to detect when the ice level is sufficiently low, and the ice demand system can then automatically trigger ice production by the ice maker 1. Another possible alternative is to include a weighing device 21 in conjunction with the holding vessel 2 itself, to determine when more ice manufacture is required. This could, for example, include a simple scale device or strain gauges on the frame, base, or sides of the holding vessel 2 connected with an integrated circuit or computing apparatus to automatically calculate weight based on the strain on the frame, base, or sides of the holding vessel 2. An agitation motor (not shown) can be located on the exterior of the holding vessel 2 and be operatively associated with an agitation device within or adjacent to the holding vessel to inhibit or prevent the ice pieces therein from freezing together and hardening. The apparatus advantageously includes an ice transferring device 3 including a first transport mechanism 22 positioned in the holding vessel and configured and adapted to transport a portion of the ice pieces in a substantially horizontal direction to facilitate removing the portion out of an aperture of the holding vessel. In a preferred mode, the ice transferring device 3 pushes the ice in a substantially horizontal direction toward the aperture, and typically in conjunction with an inclined second transport mechanism, facilitates transport of the ice pieces through the aperture in the holding vessel 2. The first transport mechanism can include, for example, a conveyor belt, a chain, a plurality of side-by-side rollers disposed transverse to the substantially horizontal direction, or the like, or any combination thereof. Preferably, a chain is included. The first transport mechanism is preferably a continuously operable loop, and is preferably motorized.
Optionally, but preferably, the ice transferring device further includes a second transport mechanism that is operatively associated with the first transport mechanism and that operates to move ice pieces from the mass of ice pieces in the holding vessel at an angle downwards into and through the aperture. The mass of ice pieces is first transported substantially horizontally adjacent to the second transport mechanism, which then agitates the ice pieces sufficiently to move them in the downwardly angled direction. For example, the second transport mechanism can include an ice rake chain 4 and ice stop rod 5 that are inclined from the horizontal to facilitate further movement of ice pieces through the holding vessel 2 and out the aperture thereof. The ice stop rod 5 operates to stop the ice from moving too far into the inclined second transport mechanism, and when the ice mass is sufficiently adjacent to the second transport mechanism the ice stop rod 5 can be operatively associated with a trigger to an ice stop limit switch 6, which turns off the substantially horizontal motion of the ice transferring device 3, i.e., the first transport mechanism. The ice rake chain 4 rakes the ice downward towards the horizontal auger 9, either concurrently or sequentially with the substantially horizontal movement of the mass, or both, as needed to transport sufficient ice from the holding vessel 2 to the second holding vessel 20. The ice rake chain 4 and an optional support member to maintain it at a pre-selected inclined level may be disposed at different angles, but is preferably fixed at about 40 degrees to about 80 degrees from the horizontal, more preferably from about 50 to 70 degrees from the horizontal. A motor 8 is preferably operatively associated with the ice rake chain 4, the substantially horizontal auger 9, or both. The second transport mechanism, such as an ice rake chain 4 and ice stop rod 5, is typically enclosed within the insulation chamber 210 and preferably a portion thereof is present in the holding vessel 2.
Optionally, but preferably, a substantially horizontal auger 9 is configured and dimensioned to receive ice pieces from the holding vessel 2 and facilitates transport thereof to a second holding vessel, such as auger box 20, which can have a lid and optionally a limiting switch operatively associated therewith. The second holding vessel is generally sized and dimensioned to contain sufficient ice pieces to fill a container being purchased by the consumer, which second holding vessel is readily refilled from the holding vessel 2 as soon as the sufficient amount of ice pieces is removed therefrom. As the auger box 20, for example, fills with ice pieces, the optional hinged, pivotable lid is pushed upwards toward the top until it is fully opened or until an optional limit switch 11 stops the substantially horizontal auger 9 from further filling the auger box 20 with ice. From the auger box 20, the ice is generally transported to the weighing device 21, such as by the upwardly directional transport device 12. As can be seen from
By “substantially horizontal” is meant a horizontal distance across a portion of the holding vessel 2 is traversed by a plurality of the ice pieces before they exit the holding vessel 2 via an aperture 11. “Substantially” includes completely horizontal and can also mean, for example, that the ice generally moves at an average angle of no more than about 20 degrees, and preferably no more than about 10 degrees, from the horizontal, either above or below horizontal. Preferably, substantially horizontal can mean about 0.1 to 8 degrees, more preferably from about 0.2 to 5 degrees from the horizontal. In a most preferred embodiment, the angle from the horizontal is from about 0.5 to 3 degrees. Preferably, the ice pieces move in a flat or slightly downward direction during the substantially horizontal component of their transport to the aperture. A motor 7 is preferably operatively associated with the ice transferring device 3, as well as various other devices of the invention further described herein, to facilitate the rapid delivery of ice pieces to the consumer. Suitable motor size and power for any of the mechanized features of the invention herein will be readily determined by one of ordinary skill in the art with reference to the description of the invention herein.
In one embodiment, the ice transferring device 3 tilts a portion of the holding vessel 2 to facilitate transport of the ice pieces substantially horizontally to the aperture 11. In this embodiment, such a tilting mechanism can be operatively associated with the bottom surface of the holding vessel to reversibly raise an end of the bottom surface to facilitate transfer of the ice pieces out of the holding vessel 2, and an upwardly directional ice transport device 12 operatively positioned at a second end opposite the reversibly raised end of the bottom surface, which conveys the ice upwards to a weighing device 21, whereby the weighing device 21 meters out a portion of ice pieces and deposits the portion into a readily transportable container. The bottom surface of the holding vessel 2 can be raised to an inclined position, or alternatively a portion of the bottom surface, the entire holding vessel 2, or a second bottom adjacent and above the bottom surface, can be raised to an inclined position. Optionally, but preferably, a second transport mechanism, such as an ice rake chain 4 and ice stop rod 5, can be included to facilitate movement of ice as described above for the preferred embodiment. Other suitable devices to substantially horizontally transport the ice pieces to and through aperture 11 can be used, as well.
Aperture 11 may be located on the side or bottom of holding vessel 2, or both, i.e., the aperture may extend across a portion of one or more sides, a side and the bottom, or a combination thereof. The aperture 11 typically is configured and dimensioned so that blockage of the ice flow is minimized or avoided, so that sufficient ice can pass through the aperture sufficiently rapidly to minimize waiting time by the consumer, and so that ice pieces are directed into or onto an optional, but preferably present, upwardly directional ice transport device 12. This ice transport device 12 is operably positioned and configured to receive as many ice pieces as possible from the aperture. Ice pieces can exit the aperture and are retained and transported by the upwardly directional ice transport device 12. This device 12 can include any suitable device that can move ice pieces in an upwardly direction in automated fashion, including an auger, a conveyor belt, a scoop or bucket type device that has sufficiently sized or numbered scoops or buckets on a belt or chain to raise a sufficient amount of ice pieces, or the like, or any combination thereof. A motor 10 is preferably associated with the operation of the ice transport device 12 to expedite delivery of ice pieces to the consumer. In the
Advantageously, the upwardly directional transport device 12 functions to separate the melted ice, or runoff water, from the ice pieces. This runoff is shunted aside or otherwise separated from the ice pieces, such as by gravity, and preferably directed into a drain, onto the ground, or otherwise away from the apparatus to minimize rusting or other degradation or damage to the apparatus of the invention or to the still frozen ice pieces in the holding vessel 2. The ice pieces, which were optionally first upwardly directed, are then disposed on or in a weighing device 21. The weighing device 21 may include any mechanism available to those of ordinary skill in the art that is suitable for weighing ice pieces. For example, the weighing device 21 might include a load cell, pressure plate, strain gauge, displacement device such as one that displaces a pre-measured quantity of fluid, or the like. After weighing, the apparatus includes a container chute 14 though which the ice pieces are disposed and are directed into waiting transportable containers 17.
The containers 17 used to capture ice pieces from the apparatus are preferably readily transportable so that consumers may easily transport the ice where desired. Thus, although the term “bagged ice” is used herein, it should be understood that any of a variety of readily transportable containers may be used so long as they can support the weight of the portion of ice to be delivered therein. Readily transportable containers 17 can thus include bags, coolers, boxes, drums, trash cans, kegs, or the like, any of which can be stacked within the apparatus of the invention, filled with the desired amount of ice pieces by weight, sufficiently sealed to inhibit escape of ice pieces until the container is desired to be opened, and delivered to the consumer. Preferably, the container 17 includes one or more handles to facilitate a consumer's grasp thereof, such as extending from, recessed in, or integrally formed with the container 17. A preferred container 17 includes an ice bag 17, which is typically made of one or more fabric or thermoplastic materials. Conventional ice bags may also be used. Preferably, the readily transportable container 17 exists fully formed within the apparatus of the invention and contains only a single opening, which can be readily sealed in a manner sufficient to minimize or prevent the loss of ice pieces.
In a preferred embodiment, the containers 17 include pre-formed bags 17 that are pre-sealed one end, typically a bottom end that is lower than an open upper end. The open end of each container 17 is preferably opened before, or concurrently with, ice pieces being weighed on the weighing device 21 so that each container 17 is ready for the pre-measured portion of ice pieces to be disposed therein. The ice pieces are typically disposed by gravity from the weighing device 21 into each container 17, such as by tilting the weighing device 21 or opening an aperture in a lower portion of the weighing device 21. The container 17 below the weighing device 21, if not already opened, is preferably blown open by a fan 18, although any suitable mechanism to open the containers or bags may be included. Preferably, a positioning device 15 pulls the filled container into a closing device 16. The positioning device 15 is positioned and configured to pull, push, or otherwise transfer each container from a container supply (not shown) into position for receiving a weighed portion of ice pieces. An exemplary positioning device is a grabbing arm. Another suitable positioning device can hold the sides of each container adjacent the top, optionally pulling a portion of the container 17 by vacuum to facilitate opening the container 17. When rigid, self-supporting containers like foam or plastic coolers are the containers, the positioning device 15 can include a conveyor belt or a rotating supply device to place the containers in position to receive weighed ice pieces.
The closing device 16 seals the bag or other container using any available fastener, including staples, ties (wire, plastic, etc.), heat sealing, adhesive, or the like. Preferably, the closing device 16 operates without use of adhesive or heat sealing, which can affect the ice pieces such as by contaminating them with chemicals from the adhesive or a melted portion of the container. In a more preferred embodiment, the closing device is a bag tier 16 that ties off the open end of each container 17 sufficiently to minimize or avoid loss of ice pieces from the container 17. The ties can include any suitable tie material, such as wire, plastic, paper, fabric, or the like, or any combination thereof. The containerized ice pieces then optionally, but preferably, drop down a container slide 19 for retrieval by the consumer. The containers may be provided where consumers can view the ice being disposed therein and seeing the container 17 being sealed as a novelty to entertain the consumer while containerizing and delivering the ice, however, it is typically desired to provide only a finished product, i.e., sealed container 17, to the consumer and to avoid or minimize exposure of parts of the apparatus outside the vending device to inhibit or avoid vandalism or other accidental breakage of such parts.
Heat sealing is preferably avoided for sealing the containers 17, as it poses the risk of melting a portion of the ice pieces, causes the ice pieces to aggregate together, or both. The containers 17 are preferably closed by use of a staple tie or wire that folds around the open end of the container. Any suitable staple ties or wires can be used that will sufficiently seal the container 17. Preferably, the staple ties or wires are about 0.5 to 3 inches long. A one inch staple is exemplary. Rolls of staples or wire can be provided in association with a motorized device to separate the staples or cut the wire to a suitable length, and then positioned and folded around the open end of a container to sufficiently seal it. A staple machine that can be included in the apparatus is commercially available through Hamer of St. Louis Park, Mo. Another advantage of providing fresh-bagged ice that is secured by tying, such as by staples, is that securing the bag in this way permits the containers to be readily opened by removal of the tie, yet remain completely resealable with the same tie or another closure device such as a plastic, metal, or paper twist tie to which consumers typically have ready access.
