Definitions

  • the present invention relates to packaging devices. More particularly, the invention relates to a packaging device that contains reinforced elements.
  • the reinforced element enables a flexible package to stand up-right.
  • Packaging devices may be classified into two types.
  • One type is a rigid packaging device, for example, tins, bottles, canisters, cans, etc.
  • Rigid devices require the same space when the device is full or empty.
  • the cost to manufacture these devices which are often made of steel, glass or aluminum, is relatively high.
  • a second type of packaging device is a flexible packaging device, such as a pouch.
  • Flexible pouches are generally constructed of laminated plastic material. These pouches constitute a simple and cost-effective packaging device. Additionally, flexible pouches do not have the same space requirements when the pouch is full compared to when the pouch is emptied.
  • flexible pouches are a simple, cost-effective packaging device
  • flexible pouches pose several disadvantages.
  • One such disadvantage is that flexible pouches are not able to stand up-right, which complicates storage and presentation of the pouches.
  • the flexibility of the sheets constituting the pouch make it difficult to manipulate. In particular, it may be difficult to keep the pouch open and to dispense the contents properly.
  • some manufacturers have used gussets to produce self-standing packages.
  • a gusset can be present in the side and/or bottom of the pouch. The gusset allows the pouch to expand, thus covering a larger surface area and allowing the pouch to be self-standing.
  • Gusset pouches require an increase in production time, thus, they are more expensive to produce than flexible pouches.
  • Another disadvantage of pouches is that graphic printing on the external surface of pouches often requires substantial printing machine setup time, which increases the unit cost price of the pouches. [0005 Therefore, there is a need to produce a less expensive self-standing package.
  • the aim of the invention is to make it possible to produce a flexible pouch, freed from the above disadvantages of known flexible pouches.
  • the present invention is drawn to a flexible pouch which is generally of a flattened shape and has two opposing walls in sheet form extending approximately parallel to a longitudinal median plane of the pouch.
  • the pouch is able to be self-standing by attaching reinforcement elements to the flexible pouch.
  • a specific embodiment of the present invention is a self-standing pouch.
  • the pouch includes two opposing walls in sheet form extending essentially parallel to a longitudinal median plane.
  • the pouch includes at least one reinforced element. The reinforced element enables the pouch to be self-standing.
  • Another embodiment is a device for packaging products.
  • the device is a single pouch that has two walls associated with two respective reinforcement elements.
  • the device may contain a second pouch.
  • the packaging device having two pouches is arranged such that the walls of the pouches are aligned along a direction at least approximately perpendicular to the median plane, and the walls of two adjacent pouches of the unit are fixed together by means such as one or more lines of adhesive.
  • FIG. 1A and FIG. IB are respectively a longitudinal transverse cross- section view and a side view of a first embodiment of the invention
  • FIG. 2A, FIG. 2B and FIG. 2C are side views of alternative embodiments of the present invention.
  • FIG. 3A and FIG. 3B are two diagrammatic views from the device in FIG. 1 A and FIG. 2 A, shown in two respective operating positions;
  • FIG. 4A and FIG. 4B are two diagrammatic views from above of packaging devices according to the invention according to two different embodiments;
  • FIG. 5A, FIG. 5B and FIG. 5C are three longitudinal transverse cross- section views of three embodiment variants of the invention, able to be implemented with any one of the two embodiments shown in FIG. 4A and FIG. 4B;
  • FIG. 6A and FIG. 6B are a side view and a perspective view of a packaging device according to the invention including a flexible pouch reinforced by elements having an attractive visual appearance;
  • FIG. 7A, FIG. 7B, FIG. 7C and FIG. 7D are four front views of the device in FIG. 6 A and 6B according to an embodiment variant including reclosure means of the device;
  • FIG. 8A is an elevation view of a device according to the invention having an easy opening means
  • FIG. 8B and FIG. 8C are respectively a diagrammatic representation of the upper part of the device in FIG. 8 A, and a view in partial vertical transverse cross-section of this device;
  • FIG. 9A and FIG. 9B are two views according to two different perspectives of an embodiment of the invention including two flexible pouches;
  • FIG. 9C is a diagrammatic representation of the upper part of the device in FIG. 9A and FIG. 9B.
  • FIG. 9D and FIG. 9E are respectively a horizontal cross-section view and a partial vertical transverse cross-section view of the device in FIG. 9A and FIG. 9B;
  • vertical direction is defined as corresponding to the longitudinal direction of greatest elongation of devices.
  • horizontal plane is defined as being the plane orthogonal to the vertical direction.
  • the pouch (10) is formed from a flexible material, for example, but not limited to polyolefins (oriented & cast polypropylene, low density polyethylene (LDPE), medium density polyethylene (MDPE), high density polyethylene (HDPE)), polyamide (nylon), polyethylene terephthalate and glycol copolymer, paper, foil, ethylene vinyl alcohol, poly(vinyl chloride), polyvinlidene chloride, acrylonitrile-butadiene- styrene, cellulose acetate-butyrate, casein, chlorotrifluoroethylene, ethylene-ethyl acrylic acid, ethylene-methacrylic acid, ethylene-propylene polymer, ethylene-vinyl acetate, linear low- density polyethylene, polyethylene manufactured using metallocene catalysts, polyacrylonitrile, polycarbonate, polychlorotrifluoroethylene, polystryrene, polytetrafluoroethylene, polyurethane, poly(vinylene), poly(vinylene), poly
  • the material used for the pouch may include, but is not limited to polyolefins (oriented & cast polypropylene, low density polyethylene (LDPE), medium density polyethylene (MDPE), high density polyethylene (HDPE)), polyamide (nylon), polyethylene terephthalate and glycol copolymer, foil, ethylene vinyl alcohol, poly(vinyl chloride), or polyvinlidene chloride. It is also envisioned that these flexible materials can be used in combination as laminations of two or more materials. All of these materials can be retorted, using standard procedures, in order to sterilize the contents of the pouch. Standard retorting processes are well known in the art of pouch manufacturing.
  • the food item may be a solid liquid or semi-solid food item examples include but are not limited to confections, baked goods, pet food, fresh food, snack food, etc.
  • the pouch may be formed using a processing line configured for the formation of the pouches from a heat sealable, continuous plastic film as is known to one skilled in the art of forming pouches.
  • a processing line configured for the formation of the pouches from a heat sealable, continuous plastic film as is known to one skilled in the art of forming pouches.
  • rolls of film are provided in which the film is fed through a plow in order to fold the sheet of film.
  • the vertical sides of the folded film are sealed as well as the bottom of the pouch if necessary.
  • This process creates a continuous strip of individual flexible pouches.
  • Quick splicing techniques can be used to change from one film to another film source.
  • the film is not printed with text or graphics.
  • a portion of the continuous plastic film can be printed with text and graphics that would be appropriate for any variety of food item and a programmable high speed printing system that imprints text on the front and/or back of each of the pouches in the continuous strip can be used to print specific text for any single variety or and single pet food product.
  • the processing line can utilize non-printed film in which the processing line would include the programmable high speed printing system for imprinting the text and graphics on the front and back of each of the pouches in the continuous strip as it runs through the printing system portion of the line.
  • a pouch (10) is formed by joining two flexible sheets (11 and 12) edge to edge to form a pouch.
  • the pouch can be any flexible pouch, for example, but not limited to a pillow pouch or a flat pouch.
  • Each pouch wall (as shown in the side view of FIG. IB) contains a top (110), a bottom (120) and coplanar sides (130) edges.
  • the top (110) and bottom (120) side edges have transverse seals.
  • the pouch edges are sealed using standard techniques that are well known and used in the art of packaging. All flexible films can be made heat sealable with coatings or co-extrusion or naturally sealable (oriented & cast polypropylene or LDPE).
  • a horizontal heat seal extends along the top edge (110) of the pouch to complete the sealing of the pouch.
  • a nip 150 is provided at the top (110) edge of the pouch (10).
  • the nips are V-shaped cut-outs extending horizontally from the top (110) edge of the pouch (10). The nips are used to initiate tearing along a horizontal line of weakness (not shown).
  • Reinforcement elements (21, 22) as shown in FIG. 1A, are bonded onto the two opposing faces of the pouch (110, 120), one opposite the other. These reinforcement elements are made of a relatively rigid material, but the material has sufficient flexibility for the elements to be distorted by the hand of a user. In specific embodiments, the reinforcement elements (21, 22) may for example be made of cardboard. Other materials may be used for the reinforcements.
  • Materials that may be used to form the reinforced elements (21, 22) include, but are not limited to polyolefins (oriented & cast polypropylene, low density polyethylene (LDPE), medium density polyethylene (MDPE), high density polyethylene (HDPE)), polyamide (nylon), polyethylene terephthalate and glycol copolymer, paper, foil, ethylene vinyl alcohol, poly(vinyl chloride), polyvinlidene chloride, acrylonitrile-butadiene-styrene, cellulose acetate-butyrate, casein, chlorotrifluoroethylene, ethylene-ethyl acrylic acid, ethylene-methacrylic acid, ethylene- propylene polymer, ethylene-vinyl acetate, linear low-density polyethylene, polyethylene manufactured using metallocene catalysts, polyacrylonitrile, polycarbonate, polycl lorotrifluoroethylene, polystryrene, polytetrafluoroethylene, polyurethane, poly(vinyl alcohol),
  • the reinforcement element (21) extends around the pouch as shown in FIG. 2A and FIG. 2B.
  • the reinforced elements can extend all the way across the pouch (10), and extend beyond it on both sides.
  • the reinforcement elements are used to provide stability to the flexible pouch so that the pouch may stand up right once the the elements have been attached to the pouch. It is envisioned that one or more reinforcement elements may cover the entire outside of the pouch (FIG. 2B) or only a portion of the outside of the pouch (FIG. 2A).
  • FIG. 2C A specific embodiment, as shown in FIG. 2C, is that the reinforcement element also covers the bottom of the pouch to enable the pouch to be self-standing.
  • the bottom of the reinforced element (23) may be a gusset bottom. This embodiment is not limited to having a gusset bottom, the bottom (23) may be in any shape that enables the pouch to be self-standing, such as an oval, circular, elliptical, or egg shape.
  • FIG. 3 A and FIG. 3B illustrate a pouch (10) which has been torn open to provide access to its content. A user places its hand on the reinforcement elements (21, 22) and moves them closer together (shown in FIG. 3A). This movement results in distortion of the reinforcement elements by arching them and separating them into their respective median parts.
  • the two opposing walls (110, 120) of the pouch which are bonded respectively to the median of the reinforcement elements (21, 22), are separated by this action.
  • the distortion of the reinforcement elements of a torn package results in an open package that can reliably be handled to effectively dispense the contained item.
  • the reinforcement elements (21, 22) may be bonded to the pouch walls by a continuous adhesive strip covering all or part of the width of the pouch wall, or by the application at discrete places or bonding points on the pouch walls.
  • bonding points may be deposited in the median area or middle of each pouch wall and/or on the lateral edges of each pouch wall. In every circumstance, it is important according to the invention for at least the median area of each pouch wall to be bonded to the reinforcement element.
  • each reinforcement element can be bonded to its associated pouch wall at the level of the two lateral edges of the pouch, in order to increase the coherence of the unit and to make it even easier to open the pouch.
  • each reinforcement element (21, 22) may be attached to its associated pouch wall by any known means other than bonding, for example, the reinforcement elements may be engaged in adjustments of the pouch walls, or the elements may be welded together.
  • the bonding of the reinforcement elements to the pouch walls may be by any mechanical and/or chemical means, for example, but not limited to heat seal, adhesives, extrusion laminate, ultrasonic seal, static seal, staples, stitches, zip strip, clamps, mesh, or punched.
  • the reinforcement elements can be used as a graphic surface to display information about the product or promotional data.
  • printing on a material such as cardboard requires an appreciably smaller amount of machine adjustment time compared with the synthetic films which usually constitute known pouches; it is thus possible, in particular where the reinforcement elements (21, 22) extend all the way up the pouch, not to print on the pouch wall, but only on the reinforcement elements which surround it.
  • FIG. 4 A shows a diagrammatic view of a pouch (10) surrounded by two reinforcement elements (21, 22), which are bonded to it. Specifically, the two reinforcement elements (21, 22) are disconnected, whereas FIG. 4B shows an alternative embodiment in which the ends of the two reinforcement elements (21, 22) are joined together.
  • the reinforcement elements (21, 22) with the pouch (10) in the form of two different flexible strips, or else of a single sleeve surrounding the pouch without discontinuity.
  • FIG. 5A to FIG. 5C show three embodiment variants, which are capable of being implemented with each of the two embodiments shown in FIG. 4 A and 4B.
  • the lower ends of the reinforcement elements (21, 22) are located underneath the pouch and are joined together by a horizontal base (23) made of the same material as the reinforcement elements.
  • This embodiment variant provides a stable base so that the pouch is able to stand up-right. It will also be noted that covering the pouch surface all the way up with the semi-rigid frame formed by the reinforcement elements (21, 22) makes it possible to offer to the hand of the user a "smoother" contact surface than that of the "crude" pouch, which may be required for some products.
  • the reinforcement elements (21, 22) extend all the way up the pouch, but their lower ends are disconnected.
  • This variant corresponds to the embodiment where the pouch is simply "sandwiched" between two flexible sides (embodiment in FIG. 5A), or surrounded by a sheath open at its two ends and the walls of the pouch is are bonded (embodiment in FIG. 5B).
  • FIG. 5C the two reinforcement elements (21, 22) have disconnected lower ends but their upper ends are covered by part (24) made from the same material.
  • part (24) made from the same material.
  • FIG. 6A and 6B show a pouch or packaging device according to the invention, corresponding to the configurations in FIG. 4B, which illustrates that the lateral ends of the reinforcement elements are joined together at specific points, and FIG. 5B, which illustrates that the lower ends of the reinforcement elements are joined together by a base.
  • the reinforcement elements have been cut so as to have a characteristic appearance, for example, a cat head.
  • Each upper corner of the reinforcement element which corresponds to a cat ear, is bonded to the opposite reinforcement element to increase the rigidity of the device.
  • Other shapes can be used, for example, but not limited to a dog, bird, or horse.
  • a package having a specific shape appearance is used as a container for that specific food item, such as a cat shaped container is used for cat food.
  • This additional element (30) can be an advertisement or promotional item.
  • the reinforcement elements do not completely enclose the pouch, the user is able to touch the pouch directly and to tactilely feel the contained product in the pouch.
  • a reinforcement structure which is more open or less open to allow more direct contact or less direct access to the product.
  • FIG. 7A to 7D are four views of the pouch in FIG. 6A and 6B once the top of the pouch has been cut.
  • FIG. 7 A it will be seen that a part of the element (21) has itself been cut out so as to constitute a tab (210).
  • the tab (210) is able to be set upright and folded back over the top of the pouch, which can be engaged into a slot (220) of the opposing reinforcement element (22) (FIG. 7B). Engaging tab (210) into slot (220) results in a closing mechanism for the pouch.
  • FIG. 7C and FIG. 7D show the embodiments of the pouch once the tab is engaged in the slot. This arrangement makes it possible to re-close the pouch when only a part of its content has been dispensed.
  • the pouch of the present invention may be made in different sizes. In particular, it is possible to provide large dimensional pouches which are manipulated with both hands so as to separate the two reinforcement elements and open the pouch.
  • a large pouch that may be used for dog food.
  • each reinforcement element can contain a pre-cut tear line, given the reference L in FIG. 8A to 8C, at the same height that the reinforceinent elements (21, 22) are bonded to the pouch.
  • the adhesive may be deposited between each reinforcement element and its associated pouch wall along two continuous lines C as shown in FIG. 8B and 8C.
  • the continuous lines C may extend approximately from one lateral edge to the other of their associated pouch wall.
  • the continuous lines C may also be parallel to their associated tear line L. It is envisioned that the tear line L runs along the vertical direction between the two lines of adhesive C. In this case, the pouch is opened by tearing off the upper part of the reinforcement elements (21, 22) (and possibly the top connecting these reinforcement elements).
  • tearing the upper part of the pouch is made easier and more reliable by bonding the pouch walls to the support elements at the same height as the tear lines of the reinforcement elements. Indeed, this arrangement makes it possible to guide the tearing of the pouch by hand, which results in an easy to open device.
  • Pouches may include opening means such as a weakening line which might be made, for example, by laser beam etching of the pouch sheet so as to reduce its thickness. It will be noted that according to the invention two notches may be located on the opposing edges of the pouch, at the same height as the weakening lines of the reinforcement elements. Such notches E are shown in FIG. 8B, in which the upper parts of each reinforcement element (21, 22) have been shown diagrammatically with their weakening line L surrounded by their two lines of adhesive C. This arrangement makes it possible to remove one stage in the process of manufacturing the pouch (such as a stage of etching the pouch walls by laser beam), allowing the manufacturing cost per pouch to be reduced.
  • opening means such as a weakening line which might be made, for example, by laser beam etching of the pouch sheet so as to reduce its thickness.
  • two notches may be located on the opposing edges of the pouch, at the same height as the weakening lines of the reinforcement elements.
  • Such notches E are shown in FIG. 8B,
  • the two lines of adhesive C constitute a "channel" which frames the desired place for tearing the walls of the pouch, and thus, plays a part in guiding the tearing of the two lines of adhesive by constituting obstacles to the tear lines of the pouch walls.
  • the design of the pouch according to the invention may also be adapted in such a way that the tear lines of the reinforcement elements define the path for opening the pouch. For example, it may be possible to have a rectilinear opening path, a curvilinear opening path, or even a path according to any required design.
  • FIG. 9A to FIG. 9E shows a packaging device containing two pouches (10, 10').
  • two pouches (10, 10') are bonded together by two lines of adhesive C, which approximately cover the lateral extent of the surface on which the two pouches are opposite one another.
  • FIG. 9D and FIG. 9E show the longitudinal median plane P of the device where the pouches may be aligned approximately perpendicular to this plane.
  • the reinforcement elements are, as in the case of the device with a single pouch, arranged symmetrically relative to the plane P. It is understood that the embodiment in FIG.
  • each pouch may be bonded to a reinforcement element (element 21' for the pouch 10', 22' for the pouch 10) by two lines of adhesive C.
  • the bonding of the elements are similar to the previous discussions of bonding, of which those discussions are hereby incorporated by reference.
  • the pouches may be opened simultaneously or sequentially.
  • the lateral edges of the two pouches (10, 10') are not opposite one another, but are offset as shown in FIG. 9A and FIG. 9D.
  • pouches of different width may also conceivable facilitate the opening of a single pouch.
  • This embodiment makes it possible to package in a single device products with different characteristics. It will be possible, for example, to package in one pouch pieces of meat with or without sauce, while the other pouch contains rice or accompanying vegetables. Thus, the possibility is offered for providing the consumer with several products, constituting a combination dish, in a same device.
  • the two (or more) pouches may contain products or chemical compounds to be mixed before use, [0055] Another advantage is that each product packaged separately in a pouch may retain its intrinsic characteristics before the pouch is opened and the respective products, which it contains, are mixed together.
  • a pouch containing a specific product and having already been re-closed to different treatments (sterilization, preservation treatments, etc.), and to join this first pouch to a second pouch not having been subjected to the same treatment so as to constitute a device such as shown in FIG. 9 A to 9E.
  • This type of device may also be practical since it allows different pouches to be opened at different times or the same time. Yet further, this device also has a high degree of safety, since it allows the manufacturer to incorporate in the different pouches the exact quantities of product which are to be mixed together.
  • this device is advantageous in terms of presentation since it allows the respective products contained in the respective pouches to be dispensed in the same receptacle. It is thus possible depending to conceive of any number of pouches aligned in series and bonded together in by their adjacent walls, preferably at the same height as notches of their lateral edges, surrounded by two reinforcement elements also bonded (or fixed to the pouches by any other known means), the reinforcement elements being able to comprise tear lines.
  • the reinforcement elements may also in this case not comprise tear lines, the pouches then being able to be equipped with opening means such as weakening lines made by laser etching.
