And the priority of US Provisional Application No. 60 / 987,588, filed on November 13, 2007. The disclosures of the above mentioned applications are hereby incorporated in their entirety.

  The present invention relates generally to flexible packaging, and more particularly to manufacturing packages having fluid-actuated and secondary seals or seals, and packages having fluid-actuated and secondary seals or seals. And a method for use.

  Conventional flexible packages generally include external or integral sliding means or other similar devices that are designed to allow the user to selectively gain access within the pouch or package. Including. Traditionally, non-integral torsional binding and other binding means have also been used to close the open end of the flexible package. These devices often require the production of additional, often expensive materials and / or devices in the package.

  Because of the problems associated with external occlusion devices for packages, the industry has developed integral occlusion devices. U.S. Pat. Nos. 4,913,561, 4,692,837 and 6,186,663 disclose such packages. Current typical reclosable devices most commonly known as zippers tend to be pre-made at a separate manufacturing location and then transported to the location where the actual package is manufactured. The reclosable device is then introduced into the packaging machinery and typically heat sealed in or on the package. These re-occlusion devices are usually composed of two parts that are meshed together by male and female interlock members. The meshing process is usually accomplished either by crushing the two interlock members together (press closure mechanism) or by sliding the mechanism (zipper mechanism) along the top of the recloseable device. It connects two interlock members.

  A press-to-close occlusion mechanism is sometimes difficult to align when attempting to mesh together and often causes correct occlusion failure. In addition, when the packer fills the package through the push closure closure mechanism and when the consumer pours the contents out of the package, a small piece of product is captured in the interlocking interlocking member track and the interlock configuration Causes tearing across the part and hinders any positive sealing. A compromise in the integrity of the seal between the interlocking interlock components is the local fracture (eg, proximal side seal) of the interlock member during consumer manufacture, transport, handling, and use. Can also be caused by. Local crushing is sufficient if any of the interlock members are plastically deformed to cause leakage.

  Furthermore, most zipper-type closure mechanisms only serve to close the top of the package by pulling or forcing the top of the front and back panels of the package together. This zipper-type closure mechanism has two significant disadvantages. First, in the closed position, the side gusset of the package is forced into contact at the end proximate to the access opening, thereby reducing the internal holding capacity of the package. Second, when the zipper-type closure mechanism is in its closed position, a space or gap may remain. The gap allows air to enter and exit the package. Zipper-type occlusions may be easier to operate for some consumers and may have more aggressive occlusions to the press closure closure mechanism, but they can be expensive and similar to the press closure closure mechanism In addition, after the package is first opened by the consumer, it often does not create an ideal barrier.

  Some designs of zipper and push closure mechanisms are suitable for maintaining a watertight or liquid tight seal. However, the interlock members of both the zipper and the press closure mechanism can also tolerate fluid leaks, and they undergo plastic deformation that, after repeated use, adversely affects the ability of the mechanism to seal the fluid. obtain. Moreover, the zipper and press closure mechanism cannot be suitable for hermetic sealing. Thus, the package contents are susceptible to other air levitation problems such as oxidation and odor release.

  Consequently, there is a need for a flexible package that substantially solves the above-mentioned problems associated with conventional package designs, structures, and manufacturing methods.

  It is an object of the present invention to maintain a higher barrier to oxygen propagation after the package is initially opened by the consumer and / or to provide a one-way release valve if desired. Such that the package can be opened and closed with a simple squeeze action. Various embodiments and teachings provided herein may be utilized with rigid or semi-rigid packages.

  Embodiments of the present invention are directed to an apparatus for sealing a package that generally includes at least one front member and a back member that are at least partially joined together, the members being at the boundary of an access opening. Respectively. The member can be a panel of the package, and the package defines an internal cavity accessible through access. The interior can store and dispense products and other objects or materials. Further, at least one web member may be joined to each of the front and back panel portions, respectively, to form at least two generally parallel chambers and / or passages that generally extend along at least a portion of the access opening. . In one embodiment, each of the chamber or chambers includes a reservoir or storage portion in fluid communication and a closure portion. In other embodiments, the chamber (each of the plurality of chambers) is a single continuous chamber over substantially the entire opening.

  In some embodiments, a fluid such as a gas (eg, air), liquid, gel, or other similar fluid is being manufactured such that the storage portion and / or the occlusion portion is generally expanded or expanded. In each chamber. Fluid regulators may be formed or arranged between the respective chambers to regulate movement and / or flow between the occlusion and storage portions.

  During use, the user squeezes or applies force or pressure to the inflatable storage portion to close the access opening. The pressure causes fluid to flow through the closed portion of the chamber and, if included, flow through the fluid regulator. The inflow of fluid inflates the occluded portions and generally faces or sits against each other, selectively blocking the access openings. To provide access to the interior of the package, the user squeezes the closed portion of the chamber, which causes fluid to be poured into the storage portion through a fluid regulator. As fluid flows into the storage portion, the closure portion contracts, allowing the user access to the interior of the package.

  For various embodiments, a pair of thin wall fluid filled chambers, each one in close proximity to the bag or package opening, eg, on either side of the flexible, rigid, semi-rigid bag or package Are configured to contact each other across the width of the flexible bag to form a seal when the opening is closed. Because of the thin wall design, the force required to maintain a seal between them is well within the elastic limits of the chamber material for repeatable sealing performance over the life of the package. The opening to the bag is made by conventional means used in the packaging industry, such as zipper closure, press closure closure, hook and loop fabric fasteners, tin tie closure, snaps, or other techniques available to those skilled in the art. Can be closed. The occlusion mechanism keeps the opening closed and keeps the fluid filled chamber in mutual contact over the length of the opening. In this way, the occlusion mechanism provides a primary occlusion and the contacting fluid-filled chamber provides a secondary seal, which can provide a leak-proof or airtight package or opening.

  Some embodiments may include more than one fluid filling chamber disposed on each side of the bag, and may be positioned such that fluid filling chambers on both sides of the bag are connected. The connecting chamber can be added to the primary occlusion mechanism, or the connecting chamber can be the only occlusion mechanism.

  Certain embodiments may include a flexible package with a fluid-actuated closure that includes an auxiliary or bypass opening that provides alternative access to the interior of the flexible package. The auxiliary opening can run substantially parallel to the fluid actuation opening and can run substantially the full width of the flexible package to allow the end user to easily fill the interior with the user-selected article. . The flexible package comprises means for sealing the auxiliary opening, such as a zipper, pinch lock, adhesive, or other closure mechanism available to those skilled in the art. After placing the article inside, the sealable part of the auxiliary opening is sealed and shielded. The flexible package can be provided to the end user in an empty state so that the end user can fill it with an article of his or her choice.

  The above summary of the present invention is not intended to describe each illustrated embodiment or every implementation of the present invention. The drawings in the detailed description that follows more particularly exemplify these embodiments.

  The invention may be more fully understood when considering the following detailed description of various embodiments of the invention in conjunction with the accompanying drawings.

While the invention is amenable to various modifications and alternative forms, specifics thereof are shown by way of example in the drawings and will be described in detail. However, it should be understood that the invention is not limited to the specific embodiments described. On the contrary, the invention is intended to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims. For illustrative purposes, cross-sectional lines or shades in the drawings are provided to demonstrate a sealing portion and / or an integral device for the package.

  Referring generally to FIGS. 1-16, a flexible package 10 in accordance with the present invention is shown. Referring generally to FIGS. 1-3, the package 10 generally includes a front panel portion 12 and a back panel portion 14. Further, in embodiments defining an upright package, a bottom panel portion 15 with or without gussets may be included. The joining and / or molding of the panels 12, 14, 15 generally defines an internal cavity 21 having an adjustable internal volume capability. The internal cavity 21 can store, transport and dispense products or other objects and materials therein. A gusseted or non-gusseted side panel portion (not shown) may also be included. Panel portions 12-15 are often referred to as webs, membranes, or layers.

  Package panel portion 12-15 is generally composed of a flexible sheet material such as polyethylene, polyester, metal foil, polypropylene, or polyethylene laminated with other materials such as nylon, polyester, and similar membranes. Is done. In order to provide a higher barrier, embodiments may use a combination layer of the materials and equivalent materials. In general, in such embodiments, a material having suitable sealing properties can be joined or bonded to a material having different suitable properties (eg, beneficial oxygen barrier properties). Preferably, the package of the present invention is intended to be formed into an upright pouch, but it can be a side-view pouch or can be other packages and pouch shapes and structures known to those skilled in the art. .

  In one embodiment, the front panel portion 12 and the back panel portion 14 are formed from one continuous web material. In an alternative embodiment, at least one of the panel portions 12-15 can be a separate web material that is bonded or sealed to each other panel portion to form the package 10 of the present invention. For example, the front panel portion 12 and the back panel portion 14 can be joined together from separate, discontinuous web sheets of material, and one of the panel portions can be further extended to define a bottom panel portion 15. Various forms of bottom panel portion 15 forming an upright pouch are known to those skilled in the art to further promote the operative expansion and contraction of package 10 and its respective ability to accept and remove material in package 10. Of gussets.

  The front panel portion 12 generally includes a first front longitudinal edge 20 and a second front longitudinal edge 22. Both of the front panel longitudinal edges 20, 22 can be substantially parallel to each other and can extend along the longitudinal length of the front panel portion 12. Similarly, the back panel portion 14 generally includes a first back longitudinal edge 24 and a second back longitudinal edge 26 that are substantially parallel to each other and span the longitudinal length of the back panel portion 14. .

  In one embodiment, the first front longitudinal edge 20 is sealably joined to the first back longitudinal edge 24 along the length of the edges 20, 24 to form a first side seal 16. Can be done. Similarly, the second front longitudinal edge 22 can be sealably joined to the second back longitudinal edge 26 along the length of the edges 22, 26 to form a second side seal 18. These side seals 16, 18 generally define the side boundaries of the package 10 and can be sealably joined using heat, adhesive, and other bonding techniques known to those skilled in the art.

  1-4, the flexible package 10 is a fluid-operated closure 30 that is attached to or integrated with the flexible package 10 to allow the user to selectively re-close the access opening 19. including. In one embodiment of the present invention, the fluid-actuated closure 30 includes at least one joined to the inner surface of the front panel portion 12 of the package 10 such that the first web barrier 32a and the second web barrier 32b are generally opposite. It includes a first web barrier or layer 32a and at least one second web barrier or layer 32b joined to the inner surface of the back panel portion 14 of the package 10 (eg, FIG. 3). Alternatively, as described herein, the barrier 32a may be opposed to a panel portion (eg, the back panel portion 14) or to selectively open and close the package 10 through sealing of the access opening 19. To face certain other structures of the package 10, only one web barrier or layer 32a is bonded to the interior of the panel portion (eg, the front panel portion, as depicted in FIG. 3A). When the access opening 19 and the fluid-actuated closure 30 are positioned along a limited portion of the package (e.g., an opening to a wet cosmetic container or package), the closure will be liquid and liquid after the initial opening of the package. Allow the air seal to store the contents.

  The front panel portion 12 and the back panel portion 14 as well as the first web barrier 32a and the second web barrier 32b are at least two fluids that extend generally transversely to the side seals and generally along the major axis of the access opening 19. Chambers or tubes 33a and 33b may be defined. In other embodiments, the fluid chambers 33a and 33b capture the barrier membrane between two layers of sealant membrane, preferably a nylon or EVOH barrier membrane that is coextruded between two layers of polyethylene, or It can be a stack formed by positioning. The fluid chambers 33a and 33b are enclosed at the top of the package 10, where typically air or gas, liquid, or similar items are contained in the first web barrier 32a and front panel portion 12 of the package 10. As well as between the second web barrier 32b of the package 10 and the back panel portion 14, or if a tube is used, it is introduced into the tube. This creates one or more generally opposing balloon-shaped bubbles in the top or compartment of the package 10. In addition, the barriers or layers 32a, 32b and the corresponding chambers 33a, 33b can be formed by, for example, folding a portion of the package 10 or the respective panels 12, 14 to create a fluid-accommodating chamber or layer. It can be formed from a part of the package 10.

  Each of the fluid chambers 33a and 33b is in fluid communication with one or more reservoirs or storage portions 34 having a nominal width 24.1 and a nominal height 34.2, and a storage portion 34 through a fluid regulator 40. May include one or more occluded portions 36 having a nominal width 26.1 and a nominal height 36.2. As shown in the package 10 of FIGS. 1, 2, and 4, the portions 35a, 35b of the package above the respective storage portion 34 of the chambers 33a, 33b are formed using known bonding or sealing techniques. Joinable from the edge 22 to a point generally shorter than the edge 20, preferably close to the fluid regulator 40. Thus, since the portion above the storage portion 34 is closed, access to the internal cavity 21 of the package 10 is generally limited to the access opening 19 proximate the closed portion 36. Other embodiments are envisioned where the access opening 19 and portions 34, 36 are located elsewhere along the package 10 (eg, along one or more sides or along the front and back panels).

A fluid regulator 40 is formed between the respective closed portion 36 and the reservoir portion 34 of the chambers 33a and 33b to regulate fluid movement and / or flow between the reservoir portion and the closed portion and / or Alternatively, it can be arranged. The fluid regulator 40 can simply be two opposing membrane portions or narrow passages 41 of material, as depicted in the face. The narrow passage 41 can be characterized by a length 40.1 and a large throat dimension 40.2. The two opposing membrane portions can define a small throat dimension (not shown) and can contact each other to provide a restrictive flow path. The fluid regulator 40 may also include methods and techniques for regulating fluid flow through various one-way or two-way valve devices, or myriad other known regulators, or such passages known to those skilled in the art ( Not shown). In general, movement of fluid from the reservoir portion 34 into the respective closed portions 36 of the respective fluid chambers 33a and 33b seals the access opening 19 of the package 10. The openings 19 are sealed because of the conforming abutment or seating of the inflated portions 36 against each other. Similarly, the movement of fluid from the respective closed portions 36 of the fluid chambers 33a and 33b into the storage portion 34 unseals the access opening 19 of the package 10.

  In one embodiment of the invention, the respective closed portion 36 and storage portion 34 of the fluid chambers 33a and 33b may each be at least partially filled with fluid. In this special state, the access opening 19 can be partially unsealed or opened. It allows the user or packer to place the product or merchandise inside the package 10. To seal the access opening 19, the user moves the storage portion 34, eg, by a constriction operation, to move substantially all of the fluid from the storage portion 34 into the respective occlusion portions 36 of the fluid chambers 33a and 33b. You can apply force on the top. Further, in order to achieve such partial occlusion or opening such that the access opening is opened or closed in steps according to the number or size of the chambers 33a, 33b, a plurality of generally separate chambers 33a, 33b or bubbles / tubes can be utilized. Such an embodiment may result in a plurality of bubbles or chambers that may result in a gradual or gradual expansion or contraction, and thus a gradual or gradual opening or closure at the access opening 19. As illustrated in FIG. 3, when substantially all of the fluid is disposed within the occlusion portion 36, they selectively block and positively seal the access opening 19. In order to facilitate occlusion, each occluded portion 36 of fluid chambers 33a and 33b need not necessarily be fully inflated to a high volume pressure. This is because only sufficient pressure is required to seat or abut the chambers 33a, 33b against each other.

  In other embodiments, the user can connect the end of the storage portion 34 near the side seal 18 between two fingers, similar to the zipper-like action that a person uses when sealing a zipper lock package. The part can be lightly pinched and squeezed (squeezed) and slid over the storage part 34 towards the regulator 40. That action typically moves fluid from the reservoir portion 34 into the occluded portion 36. Opening the occlusion portion 36 may be accomplished in the same manner by sliding a lightly squeezing grip over the occlusion portion 36 to return fluid to the storage portion 34.

  In other embodiments, the fluid regulator 40 may be adjusted to allow slow movement of fluid between the storage portion 34 and the occlusion portion 36 without applying a force. That is, the fluid regulator 40 can be configured to effectively provide a slow leak therethrough even when no external force is applied to one of the storage portion 34 and the occlusion portion 36. An exemplary and non-limiting dimensional range for a fluid actuated occlusion 30 implementing such a “slow pass” fluid regulator 40 is a length ranging from about 6 mm to about 50 mm (about 1/4 to 2 inches). It may include a narrow passage 41 with 40.1 and a large throat size 40.2 ranging from about 2 mm to about 6 mm (about 1/16 to 1/4 inch). Exemplary and non-limiting dimensions for lengths 34.2 and 36.2 for storage portion 34 and occlusion portion 36 may range from about 1/4 to 1.5 inches. With heights of 34.1 and 36.1, each can range from about 25 to 150 mm (about 1 to 6 inches). Narrower heights for the 34.1 and 36.1 dimensions (on the order of 6-10 mm) may be preferred to facilitate opening and closing of the package 10 using zipper-like motion.

  In operation, consider, for example, a “slow pass” fluid regulator 40 with a volume of air that is operated primarily to reside in the storage portion 34. The presence of more air in the storage portion 34 may be at a higher pressure than the air in it expands against the walls of the storage portion 34 and thus remains in the occlusion portion 36. The large amount of higher pressure air in the storage portion 34 remains therein for a period long enough to allow the user to remove the product from the flexible container 10 through the access opening 19 in the closure portion 36. obtain. Thereafter, the pressure differential between the storage portion 34 and the occlusion portion 36 moves slowly back into the occlusion portion 36 when the two chambers 34 and 36 are evenly approached. Due to the correct sized air volume, the occluded portion 36 is occluded when the pressure approaches equally. In some embodiments, the pressure differential between the occlusion portion 36 and the storage portion 34 does not reach evenly, but may still function to effectively contain the product.

  With this mechanism, the “slow-pass” fluid regulator 40 essentially automatically closes over a period of time, thereby maintaining product freshness even if the user forgets to reseal the bag. The gradual movement between the storage portion 34 and the occlusion portion 36 can be canceled for a quicker seal by applying an external force as described above.

  In order to access the interior of the package 10, the user needs to move fluid from the respective closed portions of the fluid chambers 33a and 33b to the storage portion 34. To move fluid from the occlusion portion 36 to the storage portion 34, the user applies force to the respective occlusion portion 36 of the fluid chambers 33a and 33b, for example, by a constriction operation. As illustrated in FIGS. 4-6, the respective occluded portions 36 of the fluid chambers 33a and 33b begin to contract as fluid flows through the regulator 40 and into the reservoir portion 34. When the respective closed portion 36 of the fluid chambers 33a and 33b is deflated, the access opening 19 is unsealed and the contents of the package 10 are accessible. The package contents may include a solid or fluid product.

  As illustrated in FIGS. 7-9, the package 10 can be released by squeezing the storage portion 34 at the top of the package 10, which causes fluid to flow through the fluid regulator 40 and the fluid chambers 33a and 33b is brought into the respective closed portions 36b. As illustrated in FIGS. 8 and 9, the first barrier film 32a and the second barrier film 32b between the front panel 12 and the back panel 14 when the respective closed portions 36 of the fluid chambers 33a and 33b are filled or expanded. Compresses and begins to fit together, leaving no or substantially no gap through which oxygen or liquid passes or leaks. This barrier function is enhanced by the abutting properties of the chambers 33a, 33b and / or the material structure of the chamber (eg, other materials having a laminate or oxygen barrier properties). The contents of the package 10 can be kept fresher for a longer period of time even after the package 10 is initially opened by the user. Materials and membranes having such barrier protective properties are known in the art and are contemplated for the practice of the present invention.

In one embodiment of the present invention, the material that defines at least one of the first barrier film 32a and the second barrier film 32b or the fluid regulator 40 adheres and / or adheres to itself or to other objects. It can be made from materials with high surface energy or electrostatic charge, such as trending saran polyvinylidene chloride or other similar films and materials. Thus, the opposing chambers 33a, 33b are generally retracted together when positioned proximally. In this embodiment, the combination of the expansion of the occlusion portion 36 of the fluid chambers 33a and 33b and the increased adhesion and / or stickiness of the first barrier film 32a and the second barrier film 32b is a combination of the objects in the fluid chambers 33a and 33b. When placed generally between the inflated occlusions 36, it ensures a positive seal of the package 10. In other embodiments, the chambers are such that each strip 33c, 33d has a tendency to stick or adhere towards each other to provide an adhesive seal that provides selective access to the package 10 and its contents. It may simply be a strip 33c, 33d of such a high energy material (not necessarily forming a chamber or tube). Thus, the strips 33c, 33d draw towards each other to provide a seal, but can be easily removed or separated to provide access to the internal cavity 21. These strips 33 c, 33 d can run over the entire length of the top of the package 10 or only along the part of the package 10 adjacent to the access opening 19. Other embodiments may utilize an adhesive or other means of pulling or bonding the membrane or chamber together.

  With reference to FIGS. 10-12, the respective fluid regulators 40 of the fluid chambers 33a and 33b may be disposed approximately midway between each side of the package 10, but are sufficient for the occlusion portion 36 and the storage portion 34. Any percentage or distance across the package 10 is envisaged as long as there is a clean air / bubble area. In one embodiment of the present invention, as illustrated in FIGS. 11 and 12, the fluid regulator 40 may include a partial seal area or multiple seals generally over or along each of the fluid chambers 33a and 33b. It can be formed by creating stop areas 42a and / or 42b. As illustrated in FIGS. 11 and 12, a fluid restriction passage 44 may be formed between the partially sealed areas 42a and 42b. The fluid restriction passage 44 is generally compressed, as illustrated in FIG. 11, so that fluid is not allowed to flow without application of force (manual, mechanical, etc.) to the expanded storage portion 34 or occlusion portion 36. May have a state that has been After application of force or other means of moving fluid, the fluid restriction passage 44 may be expanded or opened to allow fluid flow, as shown in FIG. The partially sealed region or regions 42a and / or 42b may be any shape and size that selectively restricts fluid flow between the storage portion 34 and the closed portion 36 of the fluid chambers 33a and 33b. possible. Other types of valves and fluid regulating mechanisms known to those skilled in the art may also be utilized to regulate fluid flow between chambers or package parts.

  In one embodiment of the invention, as illustrated in FIGS. 6 and 9, fluid movement between the reservoir portion 34 and the occluded portion 36 is accomplished by creating a kink or bend 46 in the fluid chambers 33a and 33b. Can be limited. In the exemplary embodiment, the kink 46 is formed when the fluid in one fluid chamber 33a or 33b is larger than the other. The fluid in the opposing fluid chambers 33a and 33b causes the fluid chamber 33a or 33b with more fluid to push further against the fluid chamber with less fluid, causing the kink 46, and the fluid over the portions 34 and 36. Limit the flow. In other embodiments, the fluid restriction passage 44 and the kink 46 may be utilized together to ensure fluid flow restriction between the storage portion 34 and the closed portion 36 of the chambers 33a and 33b.

  An intermediate seal 48 may be created just above and potentially just below the kink 46 and / or the fluid restriction passage 44 in the fluid chambers 33a and 33b, as shown in FIG. The intermediate seal 48 seals both the front panel 12 and the back panel 14 of the package 10 and ensures that they cannot be separated except where the fluid occlusion 36 of the fluid chambers 33a and 33b allows after fluid movement. To do. Further, the intermediate seal 48 may be a split point between the side of the package 10 that is accessible to the product and the side that is not accessible. The fluid restricting passage 44 and the respective fluid occlusion portions 36 of the fluid chambers 33a and 33b are of different sizes and shapes to suit the specific needs and functions of the size and shape of the package used for a particular product. possible.

  Referring to FIGS. 2-3 and 13-16, the top seal 49a is placed within the front panel portion 12 and the back panel portion 14 (approximately after product / content packaging) to seal the access opening of the package 10. Can be formed. To allow the user to easily remove or break the top seal and access the interior of the package 10 through the access opening 19, drill or laser engrave along the length of the top seal 49a to form a tear line 49b or It can be specified. Other forms of sealing such as peel and seal closures, slits, perforations, and the like may be incorporated with the package 10 and its inventive fluid-actuated closure.

  In one embodiment of the present invention, a transport device or handle 50 may be joined or formed on the package 10, as illustrated in FIG. The handle 50 may be disposed or sealed generally adjacent at least one of the fluid chambers 33a and 33b and may have a planar surface generally parallel to the front panel 12 and / or the back panel 15. In use, the handle 50 can be folded generally upward to carry the package. The handle 50 can be any size and shape. Additionally, the handle 50 can be composed of a barrier material or multiple layers similar to other parts of the package 10 to add additional strength and enhancement. This design also allows the handle to remain on the package after the consumer removes the top seal 49a to access the merchandise.

  In other embodiments of the invention, as illustrated in FIGS. 13-16, a portion of the front panel 12 or back panel 14 includes an outlet or hole 52 that allows gas in the package 10 to escape. obtain. When the closed portions 36 of the fluid chambers 33a and 33b are inflated, they can act as release valves for internal products that result in the accumulation of gas or vapor (eg, wrapping coffee), thus protecting the package 10 from rupture. At the same time, oxygen from the outside of the package 10 is prevented from entering. As illustrated in FIG. 15, as gas or vapor accumulates in the package 10, depending on the material configuration of the chambers 33 a and 33 b or the occluded portion 36, it can be pushed between two opposing occluded portions 36 and exit 52. Can leak through. As illustrated in FIG. 16, as soon as the pressure created by the gas or vapor is released, the respective occluded portions 36 of the fluid chambers 33a and 33b can re-seat with respect to each other, such as undesirable oxygen or Protects other fluids from entering the package 10 through the access opening 19.

  In other embodiments of the invention, the fluid chambers 33a and 33b may be a series of smaller fluid chambers or bubbles, long narrow rows of bubbles, or compress and / or interlock / fit with each other. It may contain shaped bubbles that enclose. Depending on the size of the access opening 19 and the degree or progress of the occlusion, different bubble shapes and structures may be utilized.

  The description appended above is typically for prefabricated packaging forms, but those skilled in the art will be able to form, fill and seal machinery or other packaging machines known to those skilled in the art. It is envisioned that this same method can be used with respect to classes. This occlusion method can be applied to packages with side gussets, or virtually any style of package, including access devices applied transversely, binding slits, separate components, and other packages with the like. Can also be used. Examples of such packages are taught in Applicant's co-pending applications US patent application Ser. Nos. 10 / 396,295, 10 / 456,971, and 10 / 954,153, which Is incorporated herein by reference in its entirety. The tubes / chambers taught herein are generally contemplated for implementation during package manufacturing or formation and / or product packaging. However, it is also envisioned that they can be pre-shaped and introduced into the package during manufacture of the package and / or during filling of the product into the package. The fluid chambers 33a and 33b or tubes can be pre-formed and / or pre-filled with air, and can be pre-applied to the main package web or material along the machined or web direction of the package or in the transverse direction. In addition, the storage portion 34 and the closure portion 36 may be provided along the side, bottom, top, or combination thereof of the package. For example, the storage portion 34 can be positioned along the side of the package proximate the longitudinal edges 20, 24, while the access opening 19 remains proximate to the top of the package. Other variations and selective positioning for portions 34, 36 are also envisioned.

  In one embodiment, the package 10 may include a constriction or closure device (not shown) that is positioned inside or outside of the package 10 to close the fluid regulator 40 or its passage 44. Such a device may prevent fluid movement between the storage portion 34 and the occlusion portion 36 and is activated when it is necessary to prevent such fluid movement during transport, storage, use, etc. Be engaged, engaged, or otherwise utilized. For example, if pressure is applied to the package 10 or portions 34, 36 thereof during transport or storage, fluid movement is restricted, thus preventing unintentional opening of the package at the access opening 19. One exemplary embodiment includes an external clip device that pinches regulator passage 44 to close fluid communication between portions 34, 36 of chambers 33a and 33b.

  Additionally, various handles, valve devices, images or displays, occlusive and re-occlusion devices, gusseted panels or parts, and equivalent functions or devices known to those skilled in the art are also used with the present invention. And may be practiced without departing from the spirit and scope of the invention. All references to front, back, bottom, and the like are for empirical purposes only and are not intended to limit the deformation, positional reference, and orientation of the panel or fluid-operated closure of the present invention. Not intended.

  With reference to FIGS. 17-21, the package 10 is depicted in an embodiment of the present invention that includes a pair of fluid chambers 54 a, 54 b proximate the opening 19. The fluid filled chambers 54 a, 54 b and the opening 19 can extend essentially the width of the package 10 or opening 19. In one embodiment, fluid-filled chambers 54a, 54b are disposed on opposing front and back panels 12, 14 respectively at substantially the same height. Interlock members 55a and 55b are disposed on the front panel 12 and the back panel 14, respectively, just above the fluid filling chambers 54a and 54b. Interlock members 55a and 55b are described in Dobreski et al. Can be a zipper closure as disclosed in US Pat. The disclosure of which is hereby incorporated by reference except for the terms expressly set forth therein. Other fastening means that may be utilized include a push closure mechanism as disclosed in U.S. Pat. No. 4,703,518 issued to Ausnit, which is hereby incorporated by reference except for terms explicitly defined therein. It is.

  The fluid filled chambers 54a and 54b may be constructed of a suitable thin walled elastic membrane known in the art of gas retention or low permeability, such as polyethylene, polyethylene / ethylene vinyl alcohol copolymer, or other suitable polymer.

  In operation, the package is closed by joining interlocking members 55a and 55b, which also contact the chambers 54a and 54b and form an interface area 56 that extends the width of the package 10 or opening 19. cause. The retention force of the interlock members 55a and 55b causes pressure on the interface region 56 to positively seal the internal cavity 21. With this configuration, the package 10 is sealed not only by the closure of the interlock members 55a and 55b, but additionally by contact between the fluid chambers 54a and 54b, which may enhance the integrity of the closure.

  With reference to FIGS. 22 and 23, the package 10 is depicted in another embodiment of the present invention. This embodiment may have all of the same components and operational features as the embodiment of FIGS. 17-20, but differs in the orientation of the interlock members 55a and 55b relative to the fluid-filled chambers 54a and 54b. Here, the interlock members 55 a and 55 b are arranged on the inner side of the interface region 56. Accordingly, the interlock members 55a and 55b can form a primary seal with the interface region 56 constituting a preliminary or secondary seal.

  With reference to FIGS. 24 and 25, another embodiment of a package 10 comprising a fluid filled chamber in contact is depicted. In this embodiment, the interlock member 55a is disposed in the interior portion of the front panel 12 between two separate fluid filling chambers 54a and 57a, and the interlock member 55b is provided with two separate fluid filling chambers 54b and 57b. It is arranged in the inner part of the back panel 14 between. In this embodiment, interlocking members 55a and 55b join to hold the two chambers 54a, 54b and 57a, 57b in contact so as to form two interface regions 56. In this way, the sealing area can be doubled or otherwise increased.

  Referring to FIGS. 26-29, the package 10 is depicted using a tin-tie closure to hold the chambers 55a and 55b in contact in an embodiment of the present invention. The tin bond occlusion can be any such device known to those skilled in the art. A pair of flap portions 58a and 58b extend upwardly from the front panel 12 and the back panel 14, respectively, above the fluid filled chamber. A tin bundle 58c having both ends extending beyond the width of the package 10 in both directions can be disposed on the outer surface of the front panel 12 adjacent to the chamber 54a.

  In operation, the package 10 is closed by pressing the flap portions 58a and 58b together and bending them downwards to form a crease or bend 58d that runs to the width of the package 10. The flap portions 58a and 58b are held in a creased position by folding the ends of the tin bundle 58c over the folded flap portions 58a and 58b or over or around the package. The chambers 54a and 54b can be held in contact by a holding force applied by a crease 58d or tin bundling force.

  In the embodiment described above depicted in FIGS. 17-29, the interlock members 55a and 55b need not provide a seal for the package 10. Rather, the integrity of the seal can be maintained by the various fluid filled chambers 54a, 54b and / or 57a, 57b. It is sufficient that the interlock members 55a and 55b function to hold the fluid filling chambers 54a and 54b and / or 57a and 57b in contact. Thus, the package 10 can continue to function correctly even if the interlock members 54a, 55b become damaged or plastically deformed from repetitive movements.

  Referring to FIGS. 30 and 31, a package 10 that includes interlocking fluid filled chambers 59a and 59b is depicted in an embodiment of the present invention. Here, a plurality of separate fluid filling chambers 59 a are formed on the front panel 12 and a plurality of separate fluid filling chambers 59 b are formed on the back panel 14. The fluid filling chambers 59a, 59b are shaped and positioned so that the fluid filling chambers 59a, 59b connect when the opening 19 is closed. These chambers 59a, 59b can be tensioned or substantially filled with fluid to provide a semi-rigid or membrane structure for connection. In a further embodiment, at least one of the chambers 59a, 59b may be replaced with a solid member (not shown) that is shaped to engage and provide a seal with the opposing fluid filled chamber. The solid member can be a rigid or flexible material.

  Functionally, the coupling (interlocking) of the fluid filling chambers 59a, 59b serves to hold the fluid filling chamber in contact and thereby seal the package 10. In this embodiment, no additional structure is required to keep the fluid filled chamber in contact and maintain a seal. However, such a closure structure as described herein can be implemented to further secure the contents of the package 10. For example, fastening means may be positioned above and below the fluid filling chambers 59a, 59b to maintain a symmetrical force against the fluid filling chambers 59a, 59b (not shown) to be coupled while providing additional fixation. obtain.

  The embodiment of FIGS. 30 and 31 depicts two fluid filled chambers on each of the opposing panels. The interlocking function is instead the two fluid-filled chambers on one panel (eg, two fluid-filled chambers 59a) and one on the opposing panel that slides between them (eg, The lower fluid filling chamber 59b only). Similarly, the interlocking function (interlocking) can be affected by more than two fluid filled chambers on each panel.

  With reference to FIGS. 32-34, a package 10 having a funnel or neck portion 60 is depicted in an embodiment of the present invention. In the depicted embodiment, neck portion 60 is defined by edge seals 16, 18 and longitudinal edges 20, 22 that converge to define throat portion 62. The throat portion 62 includes fluid filled chambers 54a and 54b so as to form an interface region 56 therebetween. The fluid filled chambers 54 a and 54 b can be formed integrally with the throat portion 62 and can be held in sealed contact by the throat portion 62.

  A top seal 64 may be integrally formed with the side seals 16 and 18 to initially seal the package 10. The top seal 64 (FIG. 33) can be removed by tearing or cutting. A conduit 65, such as a straw or tube, can be inserted between the fluid filled chambers 54a and 54b (FIG. 33b). When opposing fluid fill chambers 54a and 54b are utilized, the interface area 56 of the package 10 may serve to regulate or control the flow or outflow of contents from the package 10. Flow control can be achieved by squeezing a portion of the package to push the contents (eg, fluid) through the interface area 56. A conduit 65 that passes through the interface region 56 may further facilitate this regulation or access.

  Referring to FIGS. 35a and 35b, the throat portion 62 may be formed from two halves 62a and 62b that define recesses 66a and 66b, respectively. The fluid filled chambers 54 a and 54 b can be operatively coupled to the respective halves 62 a and 62 b of the throat portion 62. The fluid filled chambers 54a and 54b may be sized to project away from the respective recesses 66a and 66b at a distance D (FIG. 35a). After joining the first and second front longitudinal edges 20 and 22 to the first and second back longitudinal edges 24 and 26 to form the seams 16 and 18, the fluid-filled chambers 54a and 54b are halved. It is compressed into the recesses 66a and 66b of 62a and 62b (FIG. 35b).

  With reference to FIGS. 36, 36a, and 36b, in an embodiment of the present invention, only a single fluid-filled chamber 54a is utilized within the throat portion 62 to provide a sealing interface 56. The throat portion 62 and the single fluid filled chamber 54a cooperate to form an interface region 56 therebetween, as shown in FIG. The throat portion 62 generally follows the contour of the fluid filled chamber 54a, thus mitigating the formation of creases that can provide a leak path through the sealing interface 56.

  A protective film or flap 66.1 that covers at least a portion of the outer surface of the single fluid fill chamber 54a and extends between the fluid fill chamber 54a and the throat portion 62 may be included. Such a structure includes two sealing surfaces 56, one between the flap 66.1 and the fluid filling chamber 54a and the other between the flap 66.1 and the throat portion 62.

  In other embodiments of the invention, the throat-shaped portion is not required and the interfacial area 56 may be by two opposing fluid chambers or by a single fluid chamber cooperating with opposing members. Regardless, it can be designed for any known package 10 design to provide regulation of content from the package through the opening or access to the package through the opening.

  In operation, the top seal 64 may provide a fixed seal that ensures the retention of contents and the integrity of the package 10 during transport and handling. By tearing or cutting the top seal 64 (FIG. 35) and causing an internal pressure that separates the members defining the interface area 56 for its selective breaching, the contents of the package 10 are withdrawn. Obtaining allows the contents of the package 10 to flow therethrough. For example, the contents may be removed through the conduit 65 by applying a suction force to the conduit 65 or by applying a pressure pushing the content through the conduit 65 to the package 10.

  When utilized, the flap 66.1 may serve to protect the fluid filled chamber 54a from punctures when inserting the conduit 65 or from other elements that may pierce the fluid filled chamber 54a.

  The contact pressure in the interfacial area 56 can be adjusted during formation of the throat portion 62 and the fluid filling chambers 54a and 54b such that the internal pressure required to separate the fluid filling chambers 54a and 54b meets certain criteria. . The pressure at the interface region 56 formed as described above is the pressure and compressibility of the fluid in the fluid filling chambers 54a and 54b, the dimension D of the protrusion away from the recess, and the throat portion 62 and the fluid filling chamber. It is a function of several parameters, including the thickness and stiffness (modulus of elasticity) of the material including 54a and 54b. For example, fluid filled chambers 54a and 54b may be filled with a compressible gas such as air and may have a wall thickness of 0.002 to 0.004 inches. A non-limiting representative dimension D is on the order of 0.25 inches. Higher internal pressures and larger protrusions D tend to increase the pressure in the interfacial area 56, as do the greater thickness and stiffness of the throat portion 62 and fluid filled chambers 54a and 54b.

  Thus, according to one embodiment, the contact pressure is the initial hydrostatic force caused when the package 10 is tilted at the end (ie, simply the throat portion 62 is positioned below the contents of the package 10). Hence, it can be adjusted to allow the flow of the contents. In other embodiments, the contact pressure can be increased so that the interfacial area 56 is maintained regardless of the orientation of the package, such as squeezing or shaking the package 10 in order for the contents to escape. Requires additional pressure to be applied to the internal cavity 21.

  The fluid filled chambers 54 a and 54 b can also be adjusted to substantially provide a seal 67 between the inner cavity 21 and the outer surface of the conduit 65. The conduit can be used to inject or withdraw the contents of the package 10. The conduit 65 is in place, such as where the user engages in harsh activities (eg walking, cycling, or jogging), or in situations where the user is clumsy (eg, infant, disabled, or The seal 67 may limit leakage or spillage of the contents of the package 10 through the throat portion 62. The seal 67 may also limit the exposure of the contents of the internal cavity 21 to the surrounding environment as compared to situations where the throat portion is simply open to the atmosphere. The fluid filled chambers 54a and 54b can also provide automatic sealing of the package 10 after removal of the conduit 65, thereby limiting contamination or spillage of the package contents when the conduit 65 is not in place.

  With reference to FIGS. 37-41, a package 10 utilizing a gusseted side 70 is depicted in another embodiment of the present invention. The fluid filled chambers 54a and 54b disposed on the opposing front and rear panels 12 and 14 and extending along the interior width 72 of the package 10 are such that when the package 10 is closed, the fluid filled chambers 54a and 54b are interfacial areas. 56 may be positioned near the top end 74 of the package 10 so as to contact each other to define 56. In the depicted embodiment, each of the gusseted sides 70 is characterized by a crease 76 that extends proximate to the top end 74 of the package 10 between the fluid fill chambers 54a and 54b.

  In the depicted embodiment, a clip 78 may be placed over the top end 74 of the closure package 10 to maintain the fluid filled chambers 54a and 54b in the closed position. Other fastening means such as tape, tin ties or the like may also be utilized.

  In the open position (FIGS. 37-39), the gusseted side 70 can be in an extended or semi-expanded position that allows the fluid-filled chambers 54a and 54b to remain substantially parallel to each other in the open position. . In the closed position (FIGS. 40 and 41), the gusseted side 70 is in a folded position with the crease 76 sandwiched between the fluid-filled chambers 54a and 54b. In this embodiment, the package 10 is sealed near both ends of the fluid-filled chambers 54a and 54b by aligning with the folded gusseted side 70 sandwiched between the fluid-filled chambers 54a and 54b. The

  Functionally, the gusseted side 70 provides a larger access opening to the internal cavity 21, allowing larger objects to be placed therein with greater ease, as well as the complete package provided by the gusset. Allows expansion. When the interface region 56 is formed between the fluid filled chambers 54a and 54b and between the fluid filled chambers 54a and 54b in the squeezed position and the gusseted side 70, the cavity 21 is removed from the ambient environment. Isolate and prevent accidental spillage of the contents of the package 10.

  Any of the fluid-filled chambers described herein can consist of a number of smaller pockets to define a larger chamber. Further, the fluid chamber can be applied separately to the package panel, or can be formed integrally with the package (eg, by folding the top or edge portion of the package over itself), the machine direction of the pouch or It can run in other angles or directions. In addition, chambers and other devices can be applied during package formation or any other time after the package is formed. Moreover, the fluid chamber can be applied to a flexible, semi-rigid, or rigid package, or a combination of such materials to provide sealing and closure structures and the functions disclosed herein. .

  42a-42e, a user-filled flexible package 90 having an opening 92 in combination with a fluid-actuated closure 30 is depicted in an embodiment of the present invention. The user filled flexible package 90 may include at least one fluid-actuated closure 30 that is attached to the front panel 12 or the back panel 14 of the flexible package 90. In one embodiment, user-filled flexible package 90 includes double-sided tape 94, one side of which is glued to the interior of the flexible package (eg, front panel 12) and the other side is a release liner. Protected by 96. Double-sided tape 94 may be adhered to a portion of front panel 12 on the opposite side of fluid-actuated closure 30 as depicted. Double-sided tape may span the area of the fluid-actuated occlusion 30 that includes the storage portion 34 and the restriction passage 44 or fluid regulator 40. Other known occluding techniques and methods may be used in place of tape 94 without departing from the spirit and scope of the present invention.

  In operation, the end user may open the entire length or substantial portion of the opening 92 for placement of the article within the flexible package 90. After placement of the article in the package 90, the end user removes the double-sided tape release liner 96 and pushes both the front panel 12 and the back panel 14 to expose the exposed inward surface of the double-sided tape to the fluid-operated closure 30. Of the restriction passage 44 or the fluid regulator 40 and the storage portion 34. The double sided tape 94 provides a seal between the front panel 12 and the storage portion 34 / fluid regulator 40 portion. The fluid chamber 33b of the occlusion portion 36 may cooperate with the front panel 12 to provide a selective seal. A user may apply pressure to move fluid between the storage portion 34 and the occlusion portion 36 to provide selective access to the cavity or to restrict material entering and exiting the package 10 through the access opening 92. .

  In other embodiments designed to regulate the material entering and exiting the package 10, the fluid is present only in the occluded portion 36 to face opposing package sides as described according to FIGS. . In such an embodiment, the package 10 can be squeezed such that the contents of the package 10, eg, fluid, are controllably released or extruded from the package 10, and thus selectively enter the interface area 56. (breach). In still other embodiments, along with other embodiments described herein, two opposing fluid filled chambers can also be configured with an opening 92.

  Double-sided tape 94 may include a strong adhesive that provides an essentially permanent seal between double-sided tape 94 and the sealed portion of fluid-actuated closure 30. Alternatively, the adhesive may be less strong, allowing the user to reopen opening 92 and refill the flexible package several times therethrough. Sealing means other than double-sided tape 94 are also used with the user-filled flexible package 90, such as zippers, pinch locks, hook and loop materials (eg, VELCRO), and other sealing means available to those skilled in the art. Can do. Whatever sealing means is used for the package, the sealing means can be used during manufacture or before being placed on the market. It can be sold even as a kit, with instructions provided on the tangible medium so that the consumer applies the sealing means to the package itself.

  Referring to FIGS. 43a and 43b, a flexible package 97 having an auxiliary access 98 is depicted in an embodiment of the present invention. This embodiment contrasts with the embodiment of FIGS. 42A-42E in that it includes dual fluid-filled chambers 33a and 33b and the auxiliary access 98 differs from the access opening 92. Thus, the double-sided tape 94 substantially traverses the length of the auxiliary access 98 to seal the auxiliary access 98.

  FIG. 43A depicts a double-sided tape 94 for sealing, but various sealing means may be utilized including adhesives, zippers, pinch locks, hook and loop materials.

  The user-filled flexible packages 90, 97 can be sold empty to consumers. Consumers may purchase multiple flexible packages 90 to store any product or article they desire, such as in a user-filled package (eg, VELCRO).

  Referring to FIGS. 44a-44e, a metering flexible package 100 that includes a main section 102 and a metering section connected by a passage 105 is depicted in an embodiment of the present invention. The boundary between the main compartment 102 and the metering compartment 104 is a single unit disposed in the passage 105 that cooperates with the opposing member 106 to define an interface area 56 (depicted) for sealing in the passage 105. It can be defined by one of the various fluid filled chamber devices described herein, such as fluid filled chamber 54a. The metering flexible package 100 may include a handle portion 108.

  The weighing section 104 is so named because it can be sized to accommodate a quantity of product to a known or acceptable uncertainty. The main compartment 102 may shorten in diameter to the throat portion 110 in the passage 105. A selectively sealable occlusion 114, such as a pinch lock seal (as depicted), may be disposed at the distal end 116 of the metering chamber 104. The metering chamber 104 may also include vents 118 such as slots or perforations that allow air to pass between the metering chamber 104 and the surrounding environment.

  In use, the user directs the metering flexible package 100 containing the product 120 such that the metering chamber 104 is below the main chamber 102. The user can swing the weighing package 100 as depicted by the up and down arrows 122. The vibration technique can be particularly effective for pellet-type products such as dry dog food. The downward movement of the oscillating action 122 causes a portion of the product 120 to enter the interface area 56 from the main chamber 102 into the metering chamber 104. The outlet 118 still contains the product 120 while allowing air moved by the product 120 entering the metering chamber 104 to be pushed out of the metering chamber 104 when it is present. This process may continue until the metering chamber 104 is filled. When the metering chamber 104 is filled, an amount of product 120 in the metering chamber 104 is known within acceptable uncertainties. The user then opens the selectively sealable occlusion 114 for pouring the product 120 into the metering chamber 104.

  The passage of the product between the chambers 102, 104 of the metering flexible package 100 fluid can also be achieved by squeezing one of the chambers 102, 104 to move the product into the metering chamber 104. Such an approach is particularly suitable when the chamber to be squeezed contains liquid. The idea of metering flexible package 100 is the mixing of products (e.g. mixing two liquids or mixing liquids with granular products) that are placed in adjacent chambers and separated by a fluid chamber closure. ).

  The present invention may be embodied in other specific forms without departing from its spirit or essential attributes. Accordingly, it is desirable that this embodiment be considered illustrative rather than limiting in all aspects. Similarly, the methods and techniques described above for forming the present invention are illustrative processes and are not intended to limit the methods of manufacturing / forming the present invention to those specifically defined herein. A myriad of various unspecified steps and procedures may be performed to create or form the package of the present invention.
