Definitions

  • the present invention is directed to a pouch for tobacco which comprises an integrated adhesive tab for releasably sealing the first pocket as well as to a method of producing the same.
  • Consumables like e.g. tobacco are often sold in form of a pouch package.
  • Pouches for tobacco as well as methods of manufacturing the same are well known in the art.
  • Exemplary embodiments of pouches for tobacco are disclosed in NL 1 001 119 C2 and EP 1 215 973 A1 .
  • a typical example of a classical pouch for tobacco comprises a first pocket and a flap which allows for closing of the first pocket of the pouch by folding the flap over the pocket.
  • Such pouches are filled with tobacco, sealed and wrapped for sale.
  • the pouches of the prior art comprise means for releasably close or seal the pocket of the pouch.
  • pouches wherein an adhesive tab is used for releasably sealing the pocket of the pouch.
  • Releasable adhesive tabs are usually subsequently applied to the flap of the pouch and exhibit a releasable adhesive on an inner surface of the adhesive tab in order to allow for releasably sealing the flap against the remainder of the pouch.
  • GB 2 191 938 A discloses a pouch for tobacco comprising a pocket wherein the wall of the pouch comprises a flexible sheet laminate composed of at least two layers and an integral adhesive tab for releasable sealing the pouch.
  • the pouch packages proposed in the prior art use releasable adhesive tabs which are made of additional material which is subsequently applied to the flap after formation of the pouch.
  • additional material is cost intensive, subsequently applied material may be lost during use of the pouch and additional application steps lead to more complicated manufacturing processes with increased failure rates.
  • An object of the present invention is to provide a pouch comprising a releasable adhesive tab which requires less material, is not lost and does not complicate manufacturing processes.
  • the present invention provides a pouch for tobacco comprising a first pocket and an integrated adhesive tab for releasably sealing the first pocket, wherein at least one wall of the pouch is at least partially formed of a flexible sheet laminate composed of at least a first and a second layer, characterized in that the integrated adhesive tab constitutes an integral part of the flexible sheet laminate, wherein the integrated adhesive tab comprises:
  • the integrated adhesive tab is formed into a part of one of the walls of the pouch which is formed of a flexible sheet laminate, e.g. the integrated adhesive tab is integrated into a flexible sheet laminate which is used to form a flap, front wall and/or back wall of the pouch.
  • the body of the integrated adhesive tab is formed by one of the layers of the flexible sheet laminate. The body comprises an inner surface facing a part of the second layer of the flexible sheet laminate corresponding to the part of the first layer forming the body and an outer surface opposite to the inner surface.
  • the integrated adhesive tab comprises a releasable adhesive applied to at least part of the inner surface of the body of the integrated adhesive tab and/or to the outer surface of the second layer of the flexible sheet laminate corresponding to the body of the integrated adhesive tab.
  • the integrated adhesive tab is at least partially peelable from the second layer of the flexible sheet laminate such that the pouch can be sealed by peeling the integrated adhesive tab from the second layer and sealing the integrated adhesive tab against a part of the remainder of the pouch.
  • the releasable adhesive on the inner surface of the integrated adhesive tab and/or on the outer surface of the second layer of the flexible sheet laminate corresponding to the body of the integrated adhesive tab ensures that the seal formed is releasable and can be formed multiple times at the same or different parts of the remainder of the pouch.
  • the integrated adhesive tab is integrated into the pouch without the need for additional material and without the need for further application steps. Since the integrated adhesive tab is formed into pre-existing material of the pouch, the integrated adhesive tab does not stick-out from the surface of the pouch and the integrated adhesive tab can be positioned freely within the pouch. It is not necessary that the integrated adhesive tab is located at a position which allows for successful placement of additional material or which is easily accessible for subsequent application. The process of manufacturing the pouch of the invention is less prone to failure compared to the manufacturing process of prior art pouches comprising a separate adhesive tab because further application steps to arrange the extra material for the separate adhesive tab are avoided. Furthermore, since the adhesive tab of the present invention is physically integrated into one of the walls of the pouch, the integrated adhesive tab cannot be lost during use of the pouch. In the pouch of the present invention the integrated adhesive tab can be freely positioned and, thus can be located at a position which is less prone to pollution with content of the pouch like e.g. tobacco remainders.
  • the adhesive tab of the pouch of the present invention is integrated into the pouch, i.e. is formed of material which is required already for forming at least a part of one of the walls of the pouch.
  • the integrated adhesive tab constitutes an integral part of the flexible sheet laminate used to form the pouch.
  • the body of the integrated adhesive tab forms one piece with the remainder of the flexible sheet laminate of the pouch.
  • the integrated adhesive tab is still continuously connected with the remaining part of the first layer of the flexible sheet laminate of the pouch by a remaining physical connection.
  • the integrated adhesive tab cannot be peeled off intentionally or unintentionally without destroying said remaining physical connection.
  • the integrated adhesive tab comprises a body which remains physically connected to the remaining flexible sheet laminate of the pouch such that the body is partially peelable from the second layer and can be hinged away along said physical connection.
  • the releasable adhesive present on the inner surface of the body and/or on the outer surface of the second layer of the flexible sheet laminate corresponding to the body of the integrated adhesive tab can either be exposed or covered depending on whether the body is in contact with the second layer of the flexible sheet laminate corresponding to the part of the first layer forming the body or hinged away therefrom.
  • the pouch of the invention comprises at least one wall which is at least in part formed of a flexible sheet laminate.
  • a flexible sheet laminate there are several types of pouches for tobacco known in the art.
  • the first pocket is formed only of a front and a back wall, like e.g. in a rolled pouch.
  • the first pocket may be formed of a front wall, a back wall and a bottom wall as well as optionally one or more side walls, like e.g. in a block pouch, block-bottom pouch or stand-up pouch.
  • the pouch may comprise a flap which can be regarded as part of the front, back or side wall or which may be provided as separate wall of the pouch.
  • the present invention is not limited to a certain type of pouch and in principle works with all known pouch architectures provided that at least a part of one wall of said pouch is formed of a flexible sheet laminate in which the adhesive tab is integrated.
  • the pouch of the invention can be manufactured from one single piece of flexible sheet material (also called a blank), e.g. of flexible sheet laminate, or from more than one piece of flexible sheet material.
  • the pouch of the invention can be formed of a front wall and a back wall and optionally a flap.
  • the pouch of the invention may further comprise a bottom wall and optionally one or more side walls to form the first pocket of the pouch.
  • the pouch of the invention comprises a front wall and a back wall opposed to each other and optionally a bottom wall, one or more side walls and/or a flap, wherein at least a part of one of the front wall, the back wall, the bottom wall, the side wall and the flap is formed of the flexible sheet laminate.
  • the pouch of the invention may comprise a flap, a first pocket defined by opposing front and back walls and an integrated adhesive tab for releasably sealing the first pocket, wherein at least part of one of the flap, the front wall and the back wall is formed of a flexible sheet laminate composed of at least a first and a second layer, characterized in that the integrated adhesive tab constitutes an integral part of the flexible sheet laminate, wherein the integrated adhesive tab comprises:
  • the pouch of the invention preferably comprises a flap and a first pocket formed by a front wall and a back wall which are opposed to each other.
  • the side edges of the front and back walls are sealed together, leaving a mouth region through which the interior of the first pocket of the pouch is accessible.
  • the flap is arranged at the mouth region and allows for closing of the first pocket of the pouch by folding the flap over the pocket at or near the mouth.
  • the flap has a length sufficient to cover the mouth of the first pocket.
  • the flap has a length which exceeds the length of the first pocket so that the flap can be efficiently wrapped around the first pocket in order to close the pouch.
  • the pouch may further comprise a reclosable seal provided at the mouth of the first pocket which makes it possible for the consumer to reseal the first pocket after accessing the content of the first pocket thereby further preventing loss of contents by spillage from the pocket.
  • the reclosable seal also further reduces ingress of air into the first pocket and loss of moisture from the contents of the first pocket ensuring that the content remains moist and does not dry out.
  • tobacco within the first pocket is kept fresh (by the preservation of aroma and moisture) over a prolonged period of time after the time of first use.
  • a reclosable seal may be formed e.g. by use of a pressure sensitive adhesive, by a zip-based seal or the like.
  • the flap and the back wall of the pouch of the invention can be formed from a single piece of flexible sheet material, e.g. of a flexible sheet laminate.
  • the front wall of the pouch can then be built from a second piece of flexible sheet material, e.g. of a flexible sheet laminate.
  • the first pocket of the pouch can be formed by adhesively bonding a second smaller piece of flexible sheet material, e.g. of flexible sheet laminate, along three of its edges to the first sheet.
  • At least one of the two pieces of flexible sheet material is made of flexible sheet laminate composed of at least a first and a second layer.
  • the pouch of the present invention is formed from a single piece of flexible sheet laminate by folding the front wall part over the back wall part and adhesively bonding the overlapping side edges of the front and back wall to form the first pocket of the pouch.
  • the portion of the single piece of flexible sheet laminate extending beyond the mouth of the first pocket forms the flap which can then be used to fold over the first pocket.
  • the flap, front and back wall of the pouch are all formed of a flexible sheet laminate and even more preferably, flap, front and back wall of the pouch are all formed of one single piece of flexible sheet laminate. If flap, front wall and back wall of the pouch of the invention are made from one single piece of flexible sheet laminate, e.g. in form of a blank, it is easily possible to arrange the integrated adhesive tab of the invention at any desired position and to provide a pre-prepared blank already comprising the integrated adhesive tab.
  • such a pre-prepared blank can be identical in size and dimension compared to a classical blank without an integrated adhesive tab of the invention and, thus, such a pre-prepared blank can be processed further into the pouch of the invention by using conventional manufacturing means and processes. Folding as well as welding steps and weld position can remain unaltered compared to classical pouch manufacturing without the integrated adhesive tab of the invention. Thus, no further adaptation of downstream processing is needed in contrast to conventional pouches except that subsequent application of an adhesive tab can be omitted.
  • the front wall and the back wall of the pouch of the invention can be formed of separate pieces of flexible sheet material with the proviso that at least one of them is at least in part formed of a flexible sheet laminate. It is possible that only one, either the back wall or the front wall, is formed of a flexible sheet laminate wherein the other is formed of a different flexible sheet material which is not a flexible sheet laminate. This allows saving of material and costs as well as weight because the amount of flexible sheet laminate needed is reduced.
