Cross-reference to related applications

This application claims priority to U.S. Provisional Patent Application No. 63/140,639 (filing date: January 22, 2021, title: "PACKAGE CONFIGURED TO PRESERVE PERISHABLE PRODUCT, AND METHOD OF MAKING AND USING SAME"), and the objection The disclosure is incorporated herein by reference.

Technology field

The disclosed technology generally utilizes packages to accommodate products such as, but not limited to, food products or perishable items, and/or active members, for example, to preserve the product therein and/or prevent its contamination. and/or to a method of forming packaging to increase the effectiveness of an active member.

Many types of packaging require, or at least benefit from, controlled environmental conditions. For example, some products require an environment with a specific narrow window for relative humidity or the absence of moisture within the package. Other products decompose in the presence of ethylene. Still, other products, for example agricultural products such as lettuce, are at risk of exposure to contamination and could benefit from methods to address contamination, for example through the release of antibacterial compounds in the voids of the package.

In the packaging industry, there are two types of form fill and seal machines: horizontal form fill and seal machine (HFFS) and vertical form fill machine (HFFS). and seal machine (VFFS) are widely used. One difference between these two types of machines is the way products (e.g., groceries) are dispensed into the packages produced by these machines.

1-3, a prior art VFFS consists of a roll of film stock 101, with an opening at its upper end for receiving product 112 therein and for receiving film stock 101 thereon. It includes a tube or cylinder 107a. The prior art VFFS also includes a vertical sealing bar 102a, a pair of opposing rollers or conveyors 103a, and a pair of opposing horizontal sealing bars or jaws 104a. One or each horizontal sealing bar 104a includes a cutter or sharp interior 106a configured to perforate or cut the film stock. Prior art VFFS produces a final package that may be in the form of a sealed bag or pouch, for example. Typical applications for VFFS include products that are loose, granulated, kneaded, or difficult to handle (112). Prior art VFFS targets both food and non-food markets. In contrast to the prior art HFFS, as described below, the film or laminate moves vertically through the prior art VFFS.

As shown in Figures 4 and 5, the prior art HFFS consists of a plastic film roll 101, a pair of opposing bottom seam sealing bars or jaws 102b, and a pair of opposing cross sealing bars or jaws 103b. ), a pair of opposing closed sealing bars or jaws 104b, and a pair of opposing separators 105b. Prior art HFFS can produce pouches (FIG. 5) and/or nipple and cap assemblies (FIG. 4) from roll stock film 101.

In prior art HFFS, filling and sealing of the package occurs in the same device, filling may occur through the open top of the pouch, and the machine fills in the same operation in which the pouch is created and sealed. In particular, the film or laminate moves horizontally through the machine. These processes account for all aspects of manufacturing a complete pouch product, from film unwinding, pouch forming, filling and sealing. The advantage of using prior art HFFS is that it optimizes total cost of ownership and allows greater flexibility in size and shape during production. Prior art HFFS also provides manufacturers with total control of their packaging process. Other benefits include consistent packaging speeds, less cost than pre-made pouches, increased production speeds and fewer operator shifts, easy and quick cleaning between production batches, and the ability to provide readable barcodes and product information.

The key difference in which type of machine should be used is often determined by what type of product will be packaged. While prior art HFFS is best suited for products that are rigid and easily received and handled (e.g., small toys or candy bars), prior art VFFS is best suited for products that are not rigid, granulated, kneaded, or difficult to handle manually. tend to be more suitable. Prior art VFFS are often more suitable for packaging products such as sugar, liquids and chips, for example.

Various types of sealing methods can be used in a prior art HFFS or prior art VFFS. Exemplary seals that may be employed include heat sealing, ultrasonic sealing, and induction sealing. Heat sealing is based on electrical resistance and has low maintenance. Ultrasonic sealing is based on ultrasonic frequencies and creates an airtight seal. Inductive sealing is based on electromagnetic resistance and allows sealing and cooling in the same step.

Additionally, various filing methods may be used in prior art HFFS or prior art VFFS. Exemplary filing methods that can be employed include hot fill for heat treated products, clean fill for non-heat treated products, and ultra clean for cold chain distribution.

Despite the numerous advantages of HFFS and VFFS, these machines and processes for creating packages can be improved. For example, the prior art has not yet been able to address how to preserve or extend the freshness of a product within a package formed by HFFS or VFFS. The presently disclosed technology overcomes these and other drawbacks of the prior art.

One way to address the need for controlled environmental conditions for the packaging of certain products is to optionally provide an active member in the form of a film with some type of absorption, adsorption and/or release activity or capacity. This active member may optionally be an entrained polymer film with an active agent, for example a desiccant polymer or an antimicrobial releasing polymer. Optionally, the incorporated polymer film may also include a channeling agent to help control the sorption or release of a given substance. It may be desirable if the active member does not or cannot come into direct contact with the packaging.

To overcome the above and/or other shortcomings of the prior art, the presently disclosed technology relates to forming packages using a form fill and seal machine (HFFS or VFFS), optionally including at least one active member. In one alternative embodiment, the active member may be placed in a compartment adjacent (e.g. horizontally or vertically) to the compartment holding the perishable product, with two compartments sealed from the external environment and one Although the product in one compartment cannot physically contact the active agent in other compartments, gases can flow between each compartment, thereby extending the shelf life or preserving the product.

In one alternative embodiment, the present application relates to a method of forming a package using a mold fill and seal machine. The method includes sealing the first portion of the film to itself using a pair of opposing horizontal first sealing bars or jaws. The method further includes sealing the second portion of the film to itself using at least one second vertical sealing bar or jaw. The method further includes sealing the third portion of the film to itself using at least one third vertical sealing bar or jaw. The third portion may form a separator extending between the first compartment of the package and the second compartment of the package. The separator may include one or more unsealed portions and one or more sealed portions. The method further includes sealing the fourth portion of the film to itself to surround the first and second compartments.

8 shows another example of a VFFS, generally designated 170, of the disclosed technology designed to form a package with a second compartment vertically adjacent to and below a first compartment. The VFFS shown in FIG. 8 is substantially similar to that shown in FIG. 7 described above. Like elements between the two embodiments are identified with like reference numerals, and descriptions of specific similarities between the two embodiments may be omitted here for brevity.

The difference between the two embodiments is that at least one or a pair of opposing second horizontal sealing bars or jaws 175 are positioned vertically above or below the pair of opposing first horizontal sealing bars or jaws 104a. For this reason, the second vertical sealing bar(s) 154 is omitted. In this configuration, a second compartment 118 may be formed below the first compartment 116 of a given package. Optionally, the at least one active member 114 is or is otherwise adhered to the inner surface of the film before the horizontal sealing bar(s) or jaw(s) 175 create or form the one or more unsealed portions 120. Otherwise, it may become attached.

The second horizontal seal bar(s) or jaw(s) 175 may optionally extend across and beyond the width of the cylinder 107a and/or package 130.
