Definitions

  • the present invention relates to infusion packets, particularly infusion packets containing infusible material such as tea, and more particularly to apparatus and methods for producing such infusion packets.
  • infusion packets e.g. tea bags
  • infusible material e.g. leaf tea, herbal mixtures
  • double-chamber infusion packets such as those described in US 2,593,608 (A.G.F. Rambold ) have become popular.
  • the infusible material is contained in two chambers, with each chamber being attached to the other at the base and apex.
  • This type of infusion packet is thought to enable faster infusion by allowing an increased flow of water around the infusible material.
  • a drawback of double-chamber infusion packets is that they require significantly more packet material than their single-chamber counterparts.
  • DE 19507 445 A1 discloses an apparatus and a method for producing gusseted packets by drawing and sealing a tubular web along a conduit.
  • the present disclosure relates to an infusion packet comprising a single sealed compartment, the compartment having a top and a bottom defined by two transverse seals that are separated by a distance D, the transverse seals being at opposite ends of the compartment, the distance D being in the range of 40 to 70 mm, wherein the compartment comprises at least one side gusset, the side gusset consisting of two gusset panels and three gusset creases.
  • packaging infusible material in a single-chamber infusion packet comprising one or more side gussets allows the infusible material more room to move and/or improves the flow of water around the infusible material compared to a conventional single-chamber infusion packet This enables faster infusion and/or produces an infusion with more flavour. It is additionally or alternatively envisaged that a gusseted single chamber infusion packet can contain less infusible material per packet and still achieve the same infusion performance as a conventional single chamber infusion packet.
  • the size of the infusion packet is such that it has outer dimensions that are similar to those of a conventional infusion packet This means that the infusion packet can be conveniently used by consumers in the usual manner. Therefore, the distance D which separates the transverse seals is in the range of 40 to 70 mm, more preferably from 45 to 65 mm and most preferably from 50 to 60 mm.
  • the invention relates to an apparatus for producing infusion packets as defined in claim 1, the apparatus comprising a longitudinal sealer for forming a web of packaging material into a tube and a means for drawing the tubular web past an outlet of a conduit, wherein the outlet of the conduit has an external cross-section comprising at least two vertices and wherein the apparatus comprises at least one forming member for indenting the tubular web between the vertices and additionally comprises sealing elements for compartmenting the tubular web at intervals along its length, wherein the sealing elements form transverse seals across the width of the indented tubular web and are adapted such that the distance D between successive transverse seals is in the range of 40 to 70 mm.
  • the invention relates to a method of manufacturing an infusion packet from a web of packaging material as defined in claim 7 comprising the steps of:
  • infusible material refers to any infusible or soluble material which can be immersed in liquid to prepare an infusion. This process is referred to as brewing.
  • the infusible material preferably comprises plant material.
  • infusible material may comprise plant material derived from Camellia sinensis, Aspalathus linearis, Mentha piperita, Matricaria recutita and/or mixtures thereof.
  • the infusible material comprises tea solids.
  • the term "tea solids” refers to dry material extractable from the leaves of the plant Camellia sinensis var. sinensis and/or Camellia sinensis var. assamica.
  • the leaves may have been subjected to a so-called “fermentation” step wherein they are oxidised by certain endogenous enzymes that are released during the early stages of "black tea” manufacture. This oxidation may even be supplemented by the action of exogenous enzymes such as oxidases, laccases and peroxidises.
  • the leaves may have been partially fermented ("oolong tea") or may have remained substantially unfermented (“green tea”).
  • liquid permeable and “permeable to liquid” are used interchangeably to describe a water-insoluble, porous packaging material which has openings that permit liquids, especially aqueous liquids, to pass through.
  • suitable packaging materials include non-wovens, wet laid non-wovens and wovens made with polymers or cellulosic/polymer blends (e.g. cellulose or cellulose PP blends) or perforated films.
  • the packaging material may be heat-sealable or non-heat-sealable. In certain embodiments, heat-sealable packaging material is preferred in order to facilitate a high rate of infusion packet production. In other embodiments, non-heat-sealable packaging material is preferred due to its biodegradability.
  • the dynamic (continuous dunking) procedure represents a laboratory simulation of consumer preparation of an infusion involving agitation of the infusion packet
  • Figure 1 shows a view of a web of packaging material in which an elongate web 1 of liquid-permeable packaging material is travelling in a direction Z.
  • the web of packaging material has a width W.
  • a length L corresponding to one packet is indicated by boundaries 2, but the web can be of indefinite length.
  • a single infusion packet comprises a portion of the elongate web with side margins 3 along its edges, and end margins 4, 5 either side of the boundaries 2.
  • a single infusion packet consists of packaging material that covers an area A.
  • the area A is a convenient measure of the amount of packaging material required to form each infusion packet.
  • a single infusion packet according to the present invention preferably consists of packaging material that covers an area A of from 5000 to 10500 mm 2 , more preferably from 5500 to 9000 mm 2 and most preferably from 6000 to 7500 mm 2 .
  • the infusion packet will fit in a cup and/or a mug. Therefore it is desirable that the length L is not too great
  • the infusion packet should also be large enough to contain sufficient infusible material to produce a flavourful beverage. Therefore, the packet length L is preferably from 44 to 80 mm, more preferably from 48 to 75 mm and most preferably from 52 to 70 mm.
  • the web width W is from 90 to 160 mm, more preferably from 95 to 140 mm and most preferably from 100 to 125 mm.
  • a longitudinal seal 6 comprises the side margins 3 in a finished packet according to a preferred embodiment of the invention (see Figure 2c ).
  • the longitudinal seal 6 may be a fin seal or a lap seal.
  • Transverse seals 7 define the top 8 and bottom 9 of a finished packet (see Figure 3d ).
  • the transverse seals comprise the end margins 4, 5 of the web of packaging material.
  • the transverse seals 7 are formed such that they are parallel to one another and perpendicular to the longitudinal seal 6.

  • each side gusset 15 separates the front and back panels.
  • the width of each gusset panel 12 is no more than 15 mm, and the total width of each side gusset 15 (i.e. the distance between the two outer creases 14 when the gusset is fully extended) is no more than 30 mm.
  • each gusset panel 12 has a width of 3 to 10 mm, more preferably 4 to 8 mm.
  • the total width of each side gusset 15 is from 6 to 20 mm, more preferably from 8 to 16 mm.
  • Figures 2a to 2c show three different views of a partly completed packet after the formation of the longitudinal seal 6 and two side gussets 15, as per one of the preferred embodiments.
  • Figure 2a shows a perspective view of the packet viewed from the rear, with the longitudinal seal 6 running down the rear face between the two back panels 11.
  • Figure 2b shows a perspective view of the same packet viewed from the front
  • Figure 2c shows a cross-section of the partly completed packet viewed from above, showing a compartment 16 which is defined by a front face comprising a front panel 10, a rear face comprising two back panels 11 joined by a longitudinal seal 6, and two side gussets 15, with each side gusset 15 comprising two gusset panels 12.
  • Each side gusset 15 is "M"-shaped, and consists of two gusset panels 12, two outer creases 13 and one central crease 14.
  • An outer crease 13 defines the border between a gusset panel 12 and a front panel 10 or a back panel 11, while a central crease 14 defines the border between two gusset panels 12.
  • Figures 3a to 3e are a series of perspective views which illustrate a sequence of process steps that can be carried out to form an infusion packet as a continuous web 1 of liquid-permeable packaging material moves through successive operating stations.
  • a first station the side margins 3 of the web are sealed together with a longitudinal seal 6 to give the web a tubular form ( Figure 3a ).
  • the tubular web is indented so as to introduce creases that define one or more gusset(s).
  • Figure 3b shows a preferred embodiment in which two "M"-shaped side gussets 15 have been introduced into the tubular web.
  • the web travels vertically (downwards) to a sealing zone where the transverse seals 7 that define the individual packets are formed.
  • a transverse seal is formed such that it defines the bottom 9 of the present packet above the seal and the top 8 of a preceding packet below the seal ( Figure 3c ).
  • An input device delivers a dose of infusible material 17 into the tubular web and a further transverse seal 7 is formed such that it defines the top 8 of the present packet and the bottom 9 of a succeeding packet as shown in Figure 3d .
  • the tubular web is filled with doses of infusible material 17 as it is formed into a chain of packets defined by the transverse seals 7.
