Abstract
A reclosable flexible package containing an article comprising a front flexible panel and a rear flexible panel. The reclosable flexible package has at least one panel comprising a thermoplastic film which is thermoformed; a reclosable fastener means; at least one line of structural weakness in the exterior surface of the front flexible panel and at least one line of structural weakness in the exterior surface of the rear flexible panel; and a tamper-evident structure. The tamper-evident structure includes a first portion comprising the front flexible panel extending from the at least one line of structural weakness in the exterior surface of the front flexible panel to a top seal (or top seal portion) and from the at least one line of structural weakness in the exterior surface of the rear flexible panel to a top seal (or top seal portion).
Description
- The present invention relates generally to reclosable flexible packages and more specifically, to reclosable flexible packages which are thermoformed and may be hermetically sealed if desired. The invention is also concerned with a method of manufacturing the packages according to the present invention.
- Over the years, there have been a number of improvements to conventional flexible bags and packages for containing food and non-food items which have resulted in greater convenience to the consumer. Most notable improvements in the art have been the addition of reclosable and security features to the flexible package designs. For example, goods that are not used completely when the package is initially opened rely on a closure mechanism to reseal the package and keep the remaining contents fresh and contained therein. Reclosability may be accomplished by the use of a mechanical fasteners of various types. A common type of resealing mechanical fastener is the “zipper-type” having two interlocking zipper members and may include a slider device mounted on top of the fastener. The slider device which is connected to the two interlocking members, helps to engage the interlocking zipper members when the slider device is moved in a first direction along the zipper, thereby closing the package. The slider device also helps pry apart or disengage the interlocking zipper members when the slider device is moved in an opposite direction along the zipper, thereby opening the package. Non-mechanical fasteners have also been used to provide reclosability which include peelable and resealable strips and adhesives.
- Since reclosable packages can easily be opened, tamper-evident features have been added which alert the consumer to any breach of security prior to purchase. Often the tamper-evident feature is a structural feature such as a hood or shroud which covers part or all of the reclosable fastener which must be removed in order to operate to the reclosable fastener.
- By way of example, attention is directed to the following U.S. patents as representative of various approaches of packages having a reclosable and/or tamper-evident features with which the present invention relates by way of improvement:
- U.S. Pat. Nos. 4,246,288 and 4,437,293 disclose a reclosable package and a method and apparatus for making such a reclosable package.
- U.S. Pat. No. 4,823,961 to Griesbach et al. and U.S. Pat. No. 4,925,316 to Van Erden et al., describe hermetically sealed non-thermoformed packages having a reclosable fastener means comprising interlocking closure strips being operable responsive to digital pull-apart force for accessing the contents reserved in the package.
- U.S. Pat. No. 5,246,720 to Buchko describes a flexible reclosable package which is thermoformed and includes an interlocking fastener means. A score-line is provided adjacent to the top seal which facilitates the removal of the top to gain access into the package.
- U.S. Pat. No. 6,360,513 to Strand et al. discloses a non-thermoformed reclosable bag for filling with a food product. The package is provided with a zipper-type interlocking fastener means and slider device which is covered with a folded-hood structure that serves as a tamper-evident feature. Two score-lines are also included to help remove the folded-hood structure.
- U.S. Pat. No. 6,517,242 to Buchman describes non-thermoformed packages having a reclosable fastener means comprising a zipper-type interlocking closure fastener with a slider device. Disclosed are packages that are provided with a tamper-evident feature of various structures. Lines of structural weaknesses are also provided with which to aid in the removal of the tamper-evident structure.
- U.S. Patent Application No. 2003/0219176 to Koccher et al. and U.S. Patent Application No. 2003/02318811 to Hodson et al. also describe non-thermoformed packages having a reclosable fastener means comprising a zipper-type interlocking reclosable fastener means with a slider device, and lines of weakness in the package panels.
- U.S. Patent Application No. 2003/0219173 to Schneider discloses a thermoformed package having a reclosable fastener means comprising a zipper-type interlocking reclosable fastener means with a slider device and a tamper-evident structure which covers the reclosable fastener means. A line of structural weakness is provided in the non-thermoformed package panel to help in the removal of the tamper-evident structure.
- Notwithstanding the fairly high state of development in the art, packaging manufacturers are continually striving to improve the functionality of their flexible packages.
- The present invention is directed to thermoformed flexible packages suitable for packaging food and non-food items. In accordance with the present invention, the packages are provided with a reclosable fastener means which allow the consumer to open and reclose the package at his or her own discretion. The packages are further provided with a tamper-evident structure which preserves the integrity of the package before purchase and may be easily removed to gain access to the reclosable fastener means of the package. Accordingly, the packages may further be hermetically sealed to protect the food and non-food items contained therein.
- The packages of the present invention include a front flexible panel having an interior surface and an exterior surface and comprising a first thermoplastic film. The packages also include a rear flexible panel having an interior surface and an exterior surface and comprising a second thermoplastic film which is thermoformed. The front flexible panel and rear flexible panel each have a perimeter having a first peripheral side edge and an opposing second peripheral side edge, connected by a peripheral top edge and an opposing bottom peripheral edge. The interior surface of the front flexible panel is joined to the interior surface of the rear flexible panel by either a contiguous seal or a plurality of seals. The contiguous seal includes a first side seal portion, an opposing second side seal portion, and a top seal portion, an opposing bottom seal portion in which the seal portions are connected to form a seal perimeter between the front flexible panel and rear flexible panel thereby forming a receptacle cavity.

FIG. 2 is a schematic, cross-sectional view of one embodiment of the thermoformed flexible package taken along line 2-2 ofFIG. 1 . -
FIG. 3 is a partially schematic, front plan view of another embodiment of a thermoformed flexible package according to the present invention with a turned up corner having of a second example of the reclosable fastener means. -
FIG. 4 is a schematic view of one embodiment of a preferred process of manufacturing thermoformed flexible packages according to the present invention. - As used herein, the term “thermoformed” refers to a thermoplastic film or sheet which has been heated until softened and then formed, molded, drawn, or vacuum pulled into a desired shape. In the thermoforming process, a thermoplastic film sheet is fed through an oven and heated to bring it to a thermoformable temperature. The sheet is heated to a softening point and may be either immediately shaped to the desired configuration or advanced to a forming station and then drawn to a predetermined shape. Differential pressure is maintained until the film has cooled.
- As used herein, the phrase “thermoplastic film” refers to any mono-layer or multilayer polymeric materials that soften when exposed to heat and returns to its original condition when cooled to room temperature. In general, thermoplastic films may include, but are not limited to, natural polymers, biodegradable polymers, and synthetic polymers such as polyolefins, including polyethylenes, polypropylenes, polybutylenes, polyamides, polyesters, ethylene/vinyl alcohol copolymers, polyvinylidene chlorides and the like. Thermoplastic materials may also include any synthetic polymer that are cross-linked by either radiation or chemical reaction during a manufacturing process operation.
- As used herein, the term “multilayer” refers to a plurality of layers in a single film structure generally in the form of a sheet or web which can be made from a polymeric material or a non-polymeric material bonded together by any conventional means known in the art, i.e., coextrusion, extrusion coating, and lamination, vacuum vapor deposition coating, solvent coating, emulsion coating, or suspension coating or combination of one or more thereof. The multilayer films may include as many layers as desired.
- As used herein, the term “polymer” refers to the product of a polymerization reaction, and is inclusive of homopolymers and copolymers, including bipolymers, terpolymers, etc. In general, the layers of a film can consist essentially of a single polymer, or can have still additional polymers together therewith, i.e., blended therewith.
- As used herein, the phrase “structural weakness” refers to perforations, holes, score lines, laser score lines, tear lines, tear strips, cut patterns, and microperforations in a film structure specifically designed to minimize the digital force required to tear apart a portion of a film or sheet and create a predetermined tear path for removal of a portion of the film. It should be understood that the use of the phrase “structural weakness” should include an area of the package that is intentionally designed to be easily torn by the consumer to allow exposure to the reclosable fastener means.
- As used herein, the terms “joining” and “sealing” are used interchangeably and are defined as directly adhering the subject surface to the object surface using an adhesive, a cold-seal, heat-seal or other means known to those skilled in the art.
- As defined herein, the term “cold-seal” refers to the union of a surface (or portion thereof) of one film to a surface (or portion thereof) of another film or of two different portions of a surface of the same film by means of an adhesive material.
- As used herein, the term “heat-seal” refers to the union of a surface (or portion thereof) of one film to a surface (or portion thereof) of another film or of two different portions of a surface of the same film using heat and pressure. The heat-seal is achieved by bringing two surfaces or portions of a surface into contact, or at least close proximity, with one another and then applying sufficient heat and pressure to a predetermined area of the two surfaces to cause the contacting surfaces to become molten and intermix with one another, thereby forming as essentially inseparable fusion bond between the two surfaces in the predetermined area when the heat and pressure are removed therefrom and the area is allowed to cool.
- As used herein, the phrase “hermetic seal” refers a seal on a container or package that has been completely closed by fusion (heat) or other comparable means so as to prevent any external atmosphere from entering the package through the sealed area.
- As used herein, the term “tacking” refers to the step of adhering or sealing a surface of one object to a surface of a second object by either fusion (heat) or an adhesive such that the two surface are bonded temporarily. Generally, tacking a surface of one object to another surface of a second object results in a non-hermetic seal.
- Although the disclosure hereof is detailed and sufficient to enable those skilled in the art to practice the invention, the physical embodiments herein disclosed merely exemplify the invention which may be embodied in other specific structures or methods. While the preferred embodiment has been described, the details may be changed without departing from the invention, which is defined by the claims.
- The present invention is both a method and a structure resulting from the method. The method of the present invention, while unique and fully described herein, may be used on machinery known to a person of ordinary skill in the art.
- While reclosable flexible packages using various reclosable fastener means and tamper-evident structures are well known, it is believed that the advantages of the present invention are not apparent from the known reclosable packages of the prior art.
- Attention is directed to the present invention which will be described hereunder in detail with reference to the accompanying drawings mentioned above, wherein like numerals represent like parts throughout the several views.
