Description

System and Method for Forming An Indicia For Use In Vacuum Packaging

The present invention relates to a bag for vacuum packaging and to a method and apparatus for manufacturing a bag for vacuum packaging.

Methods and devices for preserving perishable foods and perishable foods, such as fish and meat, processed foods, cooked foods and leftovers, are widely known and varied. Food is susceptible to damage due to the growth of organics such as bacteria, fungi and fungi over time after food containers are opened to the atmosphere and food is exposed to the atmosphere. Most methods and devices protect food from organic-filled air to preserve food. Common methods and devices place food in a gas-impermeable plastic bag, suck it with a vacuum pump or other suction source to degas from the bag to tightly seal the bag. It includes.

Bags for vacuum packaging may consist of a first panel and a second panel, each panel consisting of a single layer of heat-sealable, plastic-based film (eg polyethylene). The panels are sealed together along a substantial portion of the periphery of the panel by heat-sealing technology to form an envelope. Perishable products or other products, such as perishable foods, are packaged into bags through unsealed portions and subsequently degassed through unsealed portions. After the perishable product is packaged in a bag and the air is degassed inside the bag, the unsealed portions are heated and pressurized so that the panels adhere to each other to seal the bag.

US Pat. No. 2,778,173, incorporated herein by reference, discloses an improved method of degassing from the bag by forming channels in at least one of the panels with the aid of an embossing technique. Air exits the bag along the channel during degassing. The embossing forms a pattern of protuberances in at least one of the panels. The protrusions can be discrete (discontinuous) pyramids, hemisphericals, etc. and are formed by pressing panels using heated female dies and male dies. The first panel is superimposed on the second panel so that the protrusions of one panel face the panel. The contact peripheral edges of the panel are sealed to each other to form an envelope having an inlet in the peripheral unsealed portion. Perishable products or other products are packaged into bags through inlets and the inlets are sealed. The opening is then drilled in a portion of the panel material through the channel, air is removed from the interior of the bag through the channel and openings and the opening is sealed. Bags of this kind require two additional steps of sealing after packaging perishable or other product into an envelope. Another additional problem is that embossing creates impressions in the plastic such that indentations are formed on the opposite side of the panel.

In order to prevent additional sealing steps, the vacuum bag is formed with first and second panels composed of laminated films. Each panel includes a heat-sealable inner layer, a gas-impermeable outer layer and any one or more intermediate layers. Such bags are described in US Pat. No. 34,929, which is incorporated herein by reference. At least one film of the at least one panel is embossed using an embossing mold to form a channel defined by the protrusion and the spacing between the protrusions, so that the air is easily degassed in the vacuum bag.

US Pat. No. 5,554,423, incorporated herein by reference, discloses another bag that can be used for vacuum packaging. The bag consists of first and second panels, each panel comprising a gas-impermeable outer layer and a heat-sealable inner layer. Multiple heat-seal strand elements are thermally bonded at regular intervals with respect to the inner layer of the first panel or the second panel. The space between the strand elements acts as a degassing channel. The strand element is extruded from an extrusion head and thermally bonded to the heat-sealable layer using a pressure roll. A separate device is needed to form the strand element, and the procedure of thermally coupling multiple strand elements to the heat-sealable inner layer at regular intervals is complicated. In addition, various types of patterns are difficult to form by the above method.

A more detailed implementation of the invention is described according to the accompanying drawings:

1A-1C show one embodiment of a vacuum bag manufacturing method according to the present invention. The vacuum bag comprises a first panel and a second panel, each panel comprising a gas-impermeable base layer 108 and a heat-sealing inner layer 106, at least one panel having an indicia. The laminating roll 102 and the cooling roll 104 are arranged such that as the melt-extruded resin is cooled, the heat-sealable inner layer 106 may be laminated to the gas-impermeable base layer 108. As shown in FIG. 1B, the gap between the laminating roll 102 and the cooling roll 104 may be adjusted according to the specifications (eg, thickness) of the panel used for vacuum packaging. The temperature of the cooling roll 104 is maintained in a range where the melt-extruded resin is sufficiently cooled to form a desired pattern. For example, a temperature range of about −15 to −10 ° C. is sufficient to adequately form the desired pattern. The temperature range of the cooling roll 104 may vary depending on the resin composition, the composition of the gas-impermeable base layer 108, environmental conditions, and the like, and may require cablibration. In addition, the chill roll 104 can be sized to have a larger diameter than the laminating roll 102, thus allowing the melt-extruded resin to contact a larger cooled surface area. For example, the diameter of the cooling roll 104 may be about 1.5-3 times (or more) compared to the diameter of the laminating roll 102.

The heat-sealable inner layer 106 typically comprises a thermoplastic resin. For example, the resin may be made of polyethylene (PE), which is suitable for preserving (storing) food and is harmless to the human body. The vacuum bag can be made by superimposing (overlapping) the two panels so that heat can be applied to a portion of the panel periphery so that the heat-sealing inner layer 106 of the two panels is in contact and forms an envelope. The thermoplastic resin can be chosen such that the two panels are strongly bonded to each other when sufficient heat is applied.

The gas-impermeable base layer 108 is supplied to the gap between the cooling roll 104 and the laminating roll 102 by a supply means (not shown). The gas-impermeable base layer may comprise polyester, polyamide, ethylene vinyl alcohol (EVOH), nylon or other materials with similar properties, may be used in the manufacturing process, and may also be heated. The gas-impermeable base layer 108 may consist of one layer or two or more layers and may be transparent so that the label can be seen through the gas-impermeable base layer 108. When using a multi-structure base layer, their total thickness is also adjusted within the allowable range for the total gas-impermeable base layer 108.

The extruder 110 is positioned such that the melt-extruded resin forms a layer on the gas-impermeable base layer 108 by feeding the melt-extruded resin into the nip between the cooling roll 104 and the gas-impermeable base layer 108. The resin is fed through nozzle 112 of the extruder 110. The temperature of the melt-extruded resin depends on the type of resin used and may typically range from about 200 to 250 ° C. The amount of resin extruded into the laminating unit 100 depends on the desired thickness of the heat-sealing inner layer 106.

According to one embodiment of the present invention, the pattern formed on the outer circumferential surface of the cooling roll 104 may include protuberances and / or other patterns forming cavities or indicia. The resin extruded from the nozzle 112 is pressed and squeezed out between the cooling roll 104 and the gas-impermeable base layer 108, wherein the protrusions of the cooling roll 104 are pressed into the resin and / or the resin is cooled on the cooling roll 104. Flows into the home. The resin is attached to the gas-impermeable base layer 108 to quickly cool and solidify in the desired pattern to form the heat sealable inner layer 106 of the panel 220 as shown in FIGS. 2A-2E. The heat-sealing inner layer 106 may comprise a method employing a post-embossing process in which the heat sealable inner layer is drawn by a die or embossed between male and female components. Alternatively, the resin can be formed by being sufficiently heated to allow the resin to flow, so that the resin is molded.

The depth (or thickness) of the mark formed on the heat-sealing inner layer 106 of the panel 220 may be determined according to the height (or depth of the groove) of the protrusion of the cooling roll 104. Thus, the shape, width and depth (or thickness) of the label can be adjusted by varying the specifications of the protrusions and / or grooves of the cooling roll 104. 3A shows a cross-sectional view of two panels according to an embodiment of the present invention, wherein the protrusions of the cooling roll 104 impress a label on the melt-extruded resin. The heat-sealing inner layer 106 may range from 0.5-6.0 mils thick at the cover, between 1.0-2.0 mils thick between the covers, and the gas-impermeable base layer 108 may range from about 0.5-0.8 mils thick. have. 3B shows a cross sectional view of two panels according to another embodiment of the invention, wherein the grooves of the cooling roll 104 form a mark on the inner layer 106. The heat-sealing inner layer 106 for another implementation may have a thickness in the range of 0.5-6.0 mils between the indicia and 0.1-80.0 mils in the indicia. The sizes of the inner layer 106 and the base layer 108 are described below, but the size is not limited thereto.

2A-2C are top views of panels formed by cold rolls 104 for use in vacuum bags, wherein heat-sealable inner layer 106 is molded such that mark 224 is formed in heat-sealable inner layer 106. . The label 224 may represent the contents of the intended bag, for example, the label may resemble a fish or a poultry. This may be useful for identifying (identifying) the contents of a bag or for identifying (identifying) pre-seasoned bags for marinating foods. Label 224 may also be a trademark, for example, representing a manufacturer or other entity. In another implementation, the cover 224 may be text such as a cooking or storage method or recipe. In another implementation, the marker 224 may correspond to a seasonal symbol, such as a snowman or jack-o-lanterns. In other implementations, the mark 224 can match the name or mark of the content owner. Those skilled in the art will know other ways of conveying information and unusual messages.

Label 224 can also be used to improve the properties of the bag. For example, as shown in FIG. 2B, a fish-like protruding marker 224 pattern can be used to suspend the contents such that liquid collects in the bag below the contents and between the markers 224. The label 224 can also serve as a channel to release air and / or other gases from the bag.

In another embodiment, the label 224 may be made of a thermoplastic resin, which is dyed or colored as needed to make the label clearer to the naked eye. The colored label 224 can be applied to the surface, for example to the surface in a separate manufacturing step. In one embodiment, as shown in FIG. 4A, the imprinted label 224 as described above may be subsequently filled with the dyed resin melt-extruded from the second extruder 450. Excess resin can be removed with knife edge 452 and the panel can be cooled to allow the dyed resin to adhere to the heat-sealable inner layer 106 to form a colored label.

In another embodiment, the grooves and / or protrusions of the chill roll 104 may comprise an ink or dye such that the formed label is colored with ink or dye and the melt-extruded resin around the label is not colored with ink or dye. The grooves and / or protrusions of the cooling roll 104 are ink by soft, saturated material which acts as an "ink pad" for the cooling roll 104 mating to the cooling roll 104 as the cooling roll 104 rotates. Or may be re-coated with a dye. In addition, the ink or dye may seep into the grooves and / or projections through the pores of the grooves and / or projection surfaces. One skilled in the art would know other ways to apply the ink to the grooves.

4B shows another embodiment in which the first layer of melt-extruded resin can be laminated to the gas-impermeable layer 108 as described above without any particular pattern. Subsequently the laminated film can be fed into a gap between the second cooling roll 444 and the second laminating roll 442, wherein the second extruder 450 corresponds to the label 224 for the melt-extruded, dyed resin. It supplies to the 2nd cooling roll 444 which has a groove | channel to make. The knife edge 452 removes excess resin as the second cooling roll 444 rotates, and the still-cooling dyed resin adheres to the laminated film to form a raised, colored label 224. do. The laminated film may also be supplied to an ink-jet printer or other printing device. Thus, for example, colored fish can be formed against a transparent background or a background of a different color.

5 shows a bag used for vacuum packaging according to an embodiment of the present invention. The vacuum bag 560 includes a first panel 520 superimposed on a second panel 522. According to this implementation at least one marker 224 is formed on at least one panel 520, 522. Panels 522 and 520 optionally include channel 562 to exhaust air and other gases from the bag. The channel 562 may be formed along a portion of the panel, as described, for example, in "Vacuum-liquid-Trap Bags", incorporated herein by reference. The heat-sealable inner layer 106 and gas-impermeable base layer 108 of the first and second panels 520, 522 are typically made of the same material, respectively, but are also heat-sealable and gas-impermeable, respectively. It can be made of other materials that represent. Moreover, at least one panel 520, 522 may be transparent to visually mark the cover.

The features and structures described above can be combined with other manufacturing techniques to form valves or other structures, trays or integrated sensors as described in other provisional patent applications incorporated herein by reference.

In other implementations, the circumferential surface of the cooling roll 104 can optionally include a knot to form a tear line (not shown) to allow the consumer to separate the bag from the roll of the bag.

As mentioned above, the heat-sealable inner layer 106 is used as the inner layer and the gas-impermeable base layer 108 is used as the outer layer. The bottom, left and right edges of the first and second panels 520, 522 are thermally coupled to each other to form an envelope that receives perishable or other product to be vacuum packed. Once a perishable or other product is placed in the vacuum bag 560, air and / or other gas may be degassed in the bag 560 with a vacuum sealer as described in US Pat. No. 4,941,310, incorporated herein by reference, for example. . Once air and / or other gases are degassed to the satisfaction of the user, heat-sealing inner layers 106 are activated by applying heat and are bonded to each other when contacted by heat to seal the inlets.
