Definitions

  • the present invention relates to a pouch, in particular a pouch for tobacco, with a cover flap and an extension flap.
  • the inner surface of the extension flap adheres to the inner surface of the cover flap.
  • pouches wherein the pouches contain a pouch front wall and a pouch rear wall which are connected to each other at the bottom and their sides but which are open at the upper edges of the pouch to form an opening to allow the consumer an access to the interior of the pouch and its contents.
  • These known pouches further comprise a relatively long flap. This relatively long flap serves the consumer as a support and, if the consumer goods are tobacco, also as an aid to roll its own cigarettes. This relatively long flap is folded in the known products forward towards the front side of the pouch and then wrapped around the bottom of the pouch and is eventually connected to the pouch rear wall.
  • Such a pouch has the advantage of providing a long flap to the consumer but has the disadvantage that two separate steps are needed to open the flap, namely a first step to open the closing mechanism on the pouch rear wall and then folding the flap around the pouch bottom in order to open the pouch and give the consumer access to the tobacco or other consumer articles.
  • EP 0 452 167 A1 and NL 2 006 781 both disclose a tobacco pouch formed by two pockets. These documents do not disclose an extension flap and a cover flap which have a width which corresponds essentially to the width of the pouch rear wall.
  • WO 2015/082386 A1 discloses a pouch comprising a reseal label. This document does not disclose an extension flap and a cover flap which have a width which corresponds essentially to the width of the pouch rear wall.
  • EP 3 138 785 A1 relates to a method of manufacturing a tobacco pouch.
  • EP 3 138 785 A1 is prior art under Article 54(3) EPC.
  • EP 3 162 730 A1 relates to a device and method for manufacturing film bags for tobacco.
  • EP 3 162 730 A1 is prior art under Article 54(3) EPC.
  • a pouch which can be easily opened with one single action.
  • a back panel that is non-split.
  • a non-split back panel or rear wall offers more space for both branding and information purposes. That means that the extension flap is not wrapped around the back panel as shown in Figure 1 , hereinafter referred to as wrapped-around solution.
  • a pouch, in particular a non-wrapped-around solution that is easy to manufacture at high speeds.
  • a pouch in its closed position as worded in claim 1 is provided.
  • the pouch comprises a pouch front wall and a pouch rear wall. An access opening is provided between the upper edges of the pouch front wall and the pouch rear wall.
  • the pouch further comprises a cover flap.
  • the cover flap depends from the pouch rear wall.
  • the pouch further comprises an extension flap.
  • the extension flap depends from the cover flap. In the closed position of the pouch, the cover flap is folded over the front wall in order to overlie the access opening. In the closed position of the pouch, the extension flap is folded between the pouch front wall and the cover flap.
  • the inner surface of the extension flap adheres to the inner surface of the cover flap. This adherence is peelable. Preferably, this adherence extends along adherence zones along the side edges of the inner surfaces of the cover flap and the extension flap.
  • each folding line which depends from the cover flap defines either a separation line between the cover flap and the pouch rear wall or defines a separation line between the cover flap and the first of the one or more extension flaps.
  • each folding line which is present along the area of the cover flap defines an end side of the cover flap.
  • the cover flap may depend from the pouch rear wall at a first folding line, the first extension flap may depend from the cover flap at a second folding line, and, optionally, each further extension flap may depend from the foregoing extension flap at a further folding line.
  • cover flap and the extension flap are non-wrapped solutions. That means that they are not folded around the bottom of the pouch as in the prior art. Instead the cover flap and the extension flaps both being folded against each other and both lying on the pouch front wall adhering to one another along the adherence zones.
  • This has the advantage to allow the consumer an easy opening of the flap and the pouch and an easy access to the pouch content such as loose tobacco.
  • the long combined cover and extension flap and their advantages are maintained.
  • due to the non-split back panel or rear wall of the pouch of the present invention more space is available for both branding and information purposes.
  • the adhered extension and cover flaps in its closed position, provide an additional pocket.
  • This pocket can store consumer articles, in particular accessories such as cigarette paper or other wrappers.
  • the pouch of the invention is easy to manufacture as the inner surface of the extension flap adheres to the inner surface of the cover flap forming adherence zones.
  • the adherence zones are preferably located along the side edges of the inner surface of the cover flap and the inner surface of the extension flap.
  • the pouch can be made of flexible plastic sheets, laminate sheets, for example laminates made from layers of paper, metal, plastics and combinations thereof.
  • the pouch front wall and the pouch rear wall are connected to each other at the bottom and at their side edges. This can either be achieved by a direct connection or via additional intermediate walls.
  • pouch side walls can be present extending between the side edges of pouch front wall and pouch rear wall.
  • a pouch bottom wall can be present extending between the lower edges of pouch front wall and pouch rear wall.
  • the upper ends of pouch front wall and pouch rear wall are not connected to each other with the consequence that an access opening results which allows the consumer to access the contents of the pouch.
  • the inner surface of the extension flap adheres to the inner surface of the cover flap.
  • the adhering surfaces are hereinafter referred to as adherence zones.
  • the adherence zones can be defined, that means local in the form of spots or thin or broader lines for example along the side edges of the extension flap.
  • Various portions of the inner surface of the extension flap may form adherence zones, for example 25 percent, preferably 50 percent, more preferably 75 percent of the inner surface of the extension flap or more adhere to the inner surface of the cover flap.
  • the adherence zones are lines along the side edges of the cover flap and the extension flap.
  • the length of the adherence zones may vary, for example, the adherence zone may extend 25 percent, preferably 50 percent more preferably 75 percent and most preferably along entire length of the side edge of the extension flap. That means, in the case of an extension of an extension flap whose side edge is 43 millimetres, the adherence zone may be from about 10 millimetres to up to 43 millimetres.
  • These lines may vary in their broadness, for example from about 1 millimetres to about 10 millimetres, preferably from about 2 to about 5 millimetres.
  • the inner surface of the extension flap can also adhere substantially throughout the inner surface of the extension flap. That means that about the entire inner surface of the extension flap adheres to the inner surface of the cover flap, for example more than 90 percent, preferably more than 95 percent and even more preferably more than 99 percent of the inner surface of the extension flap adhere to the inner surface of the cover flap.
  • the adherence may be permanent. Permanent adherence as used herein requires an opening force of from about 15 Newton to about 40 Newton, preferably from about 20 Newton to about 30 Newton.
  • the adherence is peelable. Peelable adherence as used herein requires an opening force from about 0.5 to about 15 Newton, preferably from about 1 to about 10 Newton, more preferable from about 2 to 6 Newton. There may be exclusively peelable adherence between the inner surface of the extension flap and the inner surface of the cover flap. There may be peelable adherence and permanent adherence at different areas between the inner surface of the extension flap and the inner surface of the cover flap.
  • the opening force is determined using the peel force test for pouches.
  • the peel force test for pouches measures the force needed to separate adhered surfaces, for example to separate sealed surfaces.
  • a load cell measures the force to pull apart the peelably adhered zones for 35 mm distance. 10 samples are measured during 30 minutes testing time and the average opening force is calculated. The testing is performed on a Tensile testing machine, for example commercially available under the tradename Instron 5566. Samples are conditioned for at least 24 hours at 22 ⁇ 2 °C and 60 ⁇ 5 % relative humidity before testing. The Tensile testing machine is set at 10 Newton in respect of the load cell, the speed is set at 150 millimetres per minute, the testing distance is set at 35 millimetres. The evaluation can be made using acquisition software, for example commercially available under the tradename Bluewhill.
  • the peelable adhesion of the inner surface of the extension flap and the inner surface of the cover flap can be reclosable. This means that after the peeling of the extension flap from the cover flap, the extension flap does re-adhere to the cover flap when folded back.
  • the peelable adhesion of the inner surface of the extension flap and the inner surface of the cover flap are not reclosable. This means that after the peeling of the extension flap from the cover flap, the extension flap does not re-adhere to the cover flap when folded back.
  • Permanent adhesion can be obtained using for example thermo sealing, cold sealing, ultrasound sealing or an adhesive.
  • Peelable adhesion is at least one of a chemical connection such an adhesive, thermos sealing, cold sealing, ultrasound sealing, a mechanical connection such as a hook and loop fastener, Velcro or a micro-suction surface, or an electrostatic connection.

  • the cover flap substantially covers the pocket panel.
  • Substantial coverage means a coverage of more than half of the surface of the pocket panel, preferably more than 75 percent, more preferably more than 90 percent and even more preferably more than 95 percent of the surface of the pocket panel.
  • the pocket panel is the consumer good containing part of the front panel in its fully filled state.
  • the consumer goods are preferably tobacco, more preferably loose fine cut tobacco for roll-your-own cigarettes or make-your-own cigarettes.
  • the pouch front wall and the pouch rear wall are both rectangular. Further preferably, pouch front wall and the pouch rear wall do have the same height. It is more preferred that pouch rear wall and pouch front wall are both rectangular and of same size and are directly connected to each other at their side edges and their lower edges.
  • the extension flap and the cover flap have a width which corresponds essentially to the width of the pouch rear wall. This has the advantage that, when the cover flap and the extension flap are folded, the pouch is substantially completely closed, reducing the likelihood of consumer goods falling out of open gaps at the top of the pouch.
  • the pouch front wall starts at its bottom and ends at its upper edge.
  • the pouch rear wall starts at its bottom and ends where the cover flap starts.
  • the cover flap in turn ends where the extension flap starts.
  • the extension flap ends either at its upper edge or where an optional further, second extension flap starts.
