- Figure 12 is a view similar to Figure 11 showing a modified embodiment.
- an infusion package (10) comprises a container (12) and a support (14) for the container.
- the support comprises two support members (14) by means of which the container can be mounted on a rim of a drinking vessel such as a mug or cup (15) as shown in Figure 3 of the drawings.
- the support elements can each comprise of a strip of plastics coated
- Each support member is notched at one of its ends (16) to define a projection (18).
- the projection (18) lies in the plane of the support member and projects in the lengthwise direction of the member perpendicular to the ends (16).
- the recesses (22) are aligned with and correspond in shape to the respective projections (18).
- the support members are sealed to one another and to the container (12). These seals can be heat seals.
- the arrangement of the support members is such that the end (16) of one member is disposed opposite the end (20) of the other member so that the respective projections project in opposite directions.
- Each support member has a series of score lines (24) disposed between the ends (16) and extending pe ⁇ endicular to the lengthwise direction of the member and parallel to the end (16, 20). The score lines enable the support members to be moved from a closed position ( Figure 2) to an open position as shown in Figure 3 of the drawings.
- the container is in the form of an open ended sack or bag (12).
- the bag is formed from a web of porous heat sealable material which is folded to produce a cross section which is generally W-shaped as shown in Figures 2 and 4, the central part of the W forming a deep gusset.
- the long sides (30) of the W are sealed to each other by edge seals (32) which extend from the upper to the lower end of the bag.
- the lower corners are rounded as shown at (35) in order to minimise drippage of liquid from the bag.
- the central gusset (34) forms a divider means which divides the bag or container into two compartments (36, 38). Coffee in each of these compartments is separated by the central gusset. It has been found that this type of arrangement creates a coffee drink of enhanced flavour in an acceptable time. It will be appreciated that a minimum infusion time is achieved when each compartment has substantially equal amounts of coffee therein.
- the upper open end of the bag (12) is sandwiched between the support
- the external surfaces of the bag at the open end are secured to the opposed inwardly facing surface of the support members in such a manner that the bag can be left open at the upper end as shown in Figure 3.
- the support members are sealed to one another at their ends (16, 20) by heat seals which extend parallel to the score lines (24).
- the support member (14) can be folded over so that it is disposed alongside the upper end of the bag (12). This has the advantage that the size of any sachet containing the infusion package is reduced and the open end of the bag is effectively closed so that the coffee will not spill out in transit.
- the bag In use the bag is removed from a sachet in which it has been stored and the support members are folded upwardly to bring the infusion package into the condition shown in Figure 1. A compressive force is applied to the opposite ends of the support member causing the members to bow outwardly in the region of the score lines (24). As shown in Figure 3 the result is that the
- support members adopt a generally oval configuration allowing the projections (18) to sit on the rim of a drinking vessel (15).
- the bowing of the support members opens the upper end of the bag and provides as opening through which water can be poured onto the coffee contained in the two compartments (36, 38) of the bag.
- the support members (14) can be formed by the method described in
- each support member has a crease (25) formed therein.
- the crease extends perpendicularly to the long dimension of each support member.
- Each support member has on its internal surface a series of score lines (24) disposed between the ends (16) and extending perpendicular to the lengthwise direction of the member and parallel to the end (16, 20).
- the creases (25) facilitate the movement of the support members from a closed position ( Figure 5) to an open position as shown in Figure 6 of the drawings.
- the score lines results in an eye shaped opening in the open condition.
- the support members can be produced essentially as a single flat element as shown in Figure 7 of the drawings.
- the two members are foldable about an axis (28) to the position in Figure 1.
- the axis is principally a cut line but the portions defining the two members are joined at relatively short sections 29. It will be seen that these are spaced inwardly a short distance from the end of each member so that there is a relatively long central cut line
- the bag is removed from a sachet in which it has been stored and the support members are folded upwardly to bring the infusion package into the condition shown in Figure 5.
- a compressive force is applied to the opposite ends of the support member causing the members to bow outwardly in the region of the score lines (24). This movement is facilitated by the crease (25).
- the support members adopt a generally eye shaped configuration allowing the projections (18) to sit on the rim of a drinking vessel (15).
- the bowing of the support members opens the upper end of the bag and provides as opening through which water can be poured onto the coffee contained in the two compartments (36, 38) of the bag.
- the design allows the bag to be supported from the rim of the vessel so that the coffee containing portion sits in the liquid in the vessel once the water has been poured into the bag.
- the side edges (32) of the bag are parallel. It will be appreciated that this is not essential and they could for example taper towards the bottom edge.
- apparatus for forming an infusion package of the type described with reference to Figures 1 to 7 comprises a housing 90.
- a reel 100 on which is wound a web of material for forming the container part 12 of the infusion package.
- This material may comprise any suitable porous heat sealable material used for forming infusion packets.
- the reel is carried on a cantilevered shaft 102 mounted on the housing 90.
- the web of material is fed from the reel 100 along a path 101, which can include a pivoted guide roller assembly, and a spring loaded dancing arm 103 to a forming section 108.
- the guide roller assembly allows fine adjustment of the web during operation.
- the dancing arm 103 controls web tension and can govern material unwind through a pneumatic brake.
- the forming section 108 includes a fixed plate type flow former 104 which converts the flat web into a U-shape.
- a fixed blade 106 then creates in the U-shape the gusset 34 which has been described above with reference to Figure 2 of the drawings.
- the arrangement is such that one downwardly depending portion of the W-shape, which defines one compartment of the container part, lies on one side of the blade and the other compartment lies on the other side of the blade. Guide bars are used to control the vertical alignment of the web.
- the folded material is then fed into a sealing section 110.
- a sealing section 110 In this section two sealing operations are carried out by means of electrically heated
- a heated fixed plate 112 is located centrally in the sealing section and the limbs of the W-shape locate so that they straddle the plate 112. At a first sealing position the sealing jaws create a seal profile of the form shown at
- each movable jaw operates such that it nips the web between it and the fixed plate 112 in order to form the seal profile 114 in each limb of the W-shape.
- a similar operation creates the seal profile 115.
- the seals are carried out in such a way as to retain the position of the gusset formed in the forming section. It will be appreciated that the use of a heated blade
- the sealing jaws can be operated pneumatically or by way of cams to provide the necessary sealing force.
- the web is fed into a cutting section 118 which is designed to form a cut along the line 120 through each previously formed sealed portion so that the seal formed in the sealing section forms the trailing edge of one container part and the leading edge of the next container part.
- the long edges of each compartment defined by the W-shape are not sealed to each other so that the bag part defined by the seals has a saddle like configuration.
- the cutting section is shown at 118 in Figure 8 of the drawings.
- the cutting section operates to cut a single container part from the leading edge of
- the profile of the cut effected by the cutting section is shown at 120 in Figure 9 of the drawings.
- the cutting section 118 includes an anvil and knife which are loaded together pneumatically, or via cams, in order to provide the necessary cutting force.
- the leading container part (122) is separated from the web in a subsequent operation by advancing that container part a greater distance than the web.
- a mechanism (124) ( Figure 11) for moving apart the two compartments of each container part.
- This mechanism comprises a pair of juxtaposed plates 125 which can be moved upwardly to locate in the gusset between the two compartments of each container part.
- the plates are expandable laterally to move apart those compartments to ensure that as the container part is advanced the container parts locate one on each side of and straddle the forward part 126 of an elongate beam 127.
- the web advance gripper includes a pneumatically or cam actuated clamp mounted on a linear slide which grips the web.
- the clamp and slide are driven by a cam actuated lever (125a).
- the clamp is designed to release the web and the gripper and slider are returned to their start position. Whilst the web is not being indexed forward the web is held in position by a clamp.
- the next process carried out by the apparatus is to apply support elements or tags 14 to the just formed container part.
- the machine includes a magazine 130 in which are loaded a plurality of pre-cut blanks of the type shown in Figure 7 each of which is to form a support element.
- This magazine typically has a capacity for 600 blanks. As can be seen the magazine is disposed vertically and the lowest blank is supported by a lip at the bottom end of the magazine. Suction cups operate to draw the lowest blank vertically from the stack so that the lip then supports the next blank in the stack. These suction cups are actuated pneumatically and position a blank just above the top of a container portion. Each blank is located by means of side guides and supported on its base.
- the blank is then released above the container part and driven forward with the container part by drive pins on a walking beam assembly shown generally at 132.
- the blanks are folded from their flat condition into a V-shape by means of a folding shoe. An initial fold is made over a central support to an included angle of approximately 50 0, The shoe holds the fold in this position until at a support element sealing section yet to be described completes the folding operation.
- the folding shoe is driven pneumatically or
- a sealing section 135 which comprises a
- each container part and its associated tag undergo four sealing operations. These sealing operations are designed to seal the tag to the upper open end of the container part.
- the sealing section 135 includes four sets of electrically heated jaws spaced longitudinally therealong on both sides of the tag. The sealing jaws are actuated pneumatically or via cams to provide the necessary sealing force.
- the walking beam assembly is designed to advance the container parts and tags from the bag cutting section to a filling station and during each machine cycle the containers parts with their tags are advanced approximately 130 millimetres. Beams provide a system for gripping and releasing the bags.
- a cam driven lever provides the forward and return motion to the beam.
- sealing positions are shown in Figures 9 to 12 of the drawings at 140, 141, 142 and 143.
- sealing station 140 sealing occurs along area 150
- sealing station 141 sealing occurs at areas 151
- each container part In the sealing stations 140, 141 and 142 the compartments of each container part are held apart by a relatively deep part 128 of the beam 127. In the sealing station 143 the beam 127 has a relatively shallow part 129. This is to enable the upright edges of each compartment to be sealed together at 152 except at the part where the beam part 129 passes therethrough. After being sealed at position 143 the tag is securely sealed to its container part to form an infusion package.
- the filling section Downstream of the tag sealing section is a filling section 145.
- the filling section includes a hopper 146 disposed above the path of the infusion packages.
- the mouth of the hopper includes a servo driven auger which is arranged to deliver an accurate amount of coffee which is stored in the hopper 146 to each infusion package as it passes below the mouth of the hopper.
- each package is opened by means of pneumatically or cam actuated suction cups in order to allow coffee to enter through the mouth of the package.
- the two compartments defined by the W section of the container part 12 are still disposed on opposite sides of the beam part 129 at this stage and hence coffee delivered from the hopper 146 enters both of these compartments substantially in equal quantities.
- the compartment separating means which in this embodiment is the beam part 129 plays an important function in ensuring that the two compartments receive equal quantities of coffee.
- Sensors can be provided to check that each infusion package is correctly positioned and open and the compartments of the container part can be opened by means of an air blast prior to the coffee being dispensed therein.
- the apparatus can include a vibrator for vibrating the package in order to prevent coffee bridging in the container part.
- the reject station 160 is designed to provide for automatic rejection of the packages if they do not meet certain criteria.
- each tag or support element is folded over so that is lies alongside its associated container part the fold line occurring in the container part material. This act of folding the tag over securely closes the infusion package and maintains the coffee in the container part during transit.
- a plough can be used to fold the
- the final section of the apparatus is a sachet forming section 180 which is designed to enclose each filled infusion package in a sealed sachet.
- the apparatus includes a reel 200 on which a web of material for forming the sachet is wound. Material is fed from the reel 200 along a path 201 past a spring loaded dancing arm 202 to the sachet forming section 180.
- a sachet advance gripper draws material from the reel 200 up to a sachet seal and cut module 204 which carries out the operation shown at 205 and 206 in Figure 9. The material is sealed vertically and then the sachets are then cut by forming a cut in the leading edge of the web that cut line being central to the formed
- the heated blade (112) of the sealing section (110) comprises two side by side electrically conductive blade parts which are separated by electrically insulating material. Electrical current can be supplied to the blade parts via leads (210) shown in Figure 12.
- the blade end portion (112a) is relatively thick whilst the blade end portion (112b) is relatively thin and therefore becomes hotter because of its higher resistance.
- the blade (112) is made of high resistance material such as titanium.
- the sealing section 135 also includes a centrally located heated blade (220).
- the support elements after being dispensed from hopper (130) are folded so that they straddle this blade (220)
- the blade comprises a first part (221) which is formed from phosphor bronze and a second part (222) which is formed from titanium.
- the transversely movable sealing jaws of the sealing stations in the sealing section (135) press the folded support element against the blade (220) with the upper part of a container being sandwiched between the blade (220) and the support element. Heat from the blade head seals the support element to the container upper or mouth part. Heat sealing from the inside in this manner is an efficient and effective way of carrying out this operation.
- the station shown at (225) in Figure 12 includes creasing jaws which have cooperating grooves and ridges. These jaws are actuable to engage opposite sides of the support element (14) in order to form the creases (25) described above with reference to Figures 5 to 7. Forming the creases (25) at this stage in the process rather than in the preformed blank ensures that the creases are accurately aligned.
- the support elements or tags 14 are formed from pre-cut blanks stored in a magazine 130. It is possible to also form the tags from a continuous web of material fed from a reel such as that shown at 210. Also as described the compartment separating means at the filling station comprises a beam part 129. Alternative arrangements are possible. For example a finger could be provided below the filling station 145, the finger being actuable to locate between the two compartments of each container part to hold apart those compartments. The finger can be movable upwardly to its operative position by pneumatic or cam actuating means.
