Abstract
A method of manufacturing an infusion package 10 comprising a porous-walled container 12 for an infusible substance and a support for the container by means of which the container can be mounted on a rim of a drinking vessel. The method comprises (i) making cuts in at least one web of a semi-rigid material in a direction transverse to the web length to define a plurality of support members 14, each cut defining a first end 16 of one support member and a second end 20 of an adjacent support member such that the first end includes a projection 18 and the second end includes a recess 22 the cutting of which recess produces the projection; (ii) bringing two such support members into opposed relationship with the first end of one of the support members disposed opposite the second end of the other of the support members; (iii) positioning an end region of the container between the opposed support members; and (iv) securing that end region to the support members.
Description
- The invention relates to infusion packages and particularly, but not exclusively, to infusion packages for coffee and to the manufacture of such packages.
- Conventional infusion packages for tea or coffee comprise a porous-walled container into which has been charged the tea or coffee. In use such containers are immersed in hot liquid such as water. It is known to suspend an open container such as a bag in the liquid and this has been achieved using a hanging string. In other arrangements a filter bag is provided with holding members which enable the filter by to be supported from the rim of a container for the hot liquid. One such arrangement is described in EP-A-0463181. These known arrangement can be difficult to use and not straightforward to manufacture.
- The invention provides a method of manufacturing an infusion package comprising a porous-walled container for an infusible substance and a support for said container by means of which the container can be mounted on a rim of a drinking vessel, said method comprising (i) making cuts in at least one web of a semi-rigid material in a direction transverse to the web length to define a plurality of support members, each said cut defining a first end of one said support member and a second end of an adjacent said support member such that said first end includes a projection and said second end includes a recess the cutting of which recess produces said projection; (ii) bringing two said support members into opposed relationship with the first end of one said support member disposed opposite the second end of the other said member; (iii) positioning an end region of a said container between said opposed support members; and (iv) securing said end region to said opposed support members.
- The invention also includes an infusion package comprising a semi-porous container for an infusible material and a support for said container, said support being secured to an end of said container so as to be pivotable between first, use, positions wherein the support projects generally upwardly of said container and second, non-use, positions in which the support is disposed alongside said container.
- The invention also includes an infusion package comprising a porous walled container for an infusible substance and a support by which said container can be mounted on a rim of an drinking vessel, said support comprising two oppositely disposed members to which said container is attached such that, in use, it is suspended therefrom and each having a projection at one end thereof and a correspondingly shaped recess at an opposite end thereof, and said members being such that said projections project from opposite ends of said support.
- The invention also includes an infusion package comprising a container for an infusible material and a support for said container having a projection at each end thereof by which the support can be seated on a rim of a drinking vessel, said support being defined by two support members disposed in opposed relationship and secured to one another at said ends and at least one of said supports having a zone of weakness whereby said support can be caused to deflect away from the other said support to provide an opening between said support members leading to an open end of said container.
- In order that the invention may be well understood, some embodiments thereof, which are given by way of example only, will now be described with reference to the accompanying drawings, in which:
-
FIG. 1 is a perspective view of an infusion package; -
FIG. 2 is an end view of the infusion package; -
FIG. 3 is a perspective view of a W-section web of heat sealable porous material from which the bag portion of the package is made; -
FIG. 4 is a schematic plan view of the infusion package in use; -
FIG. 5 is a cutaway view of a sachet containing the infusion package ofFIG. 1 ; -
FIG. 6 is a plan view of two webs illustrating a method of making the support members of the infusion package ofFIG. 1 ; -
FIG. 7 is a perspective view of an alternative support for an infusion package; and -
FIG. 8 a plan view of a web illustrating a method of making the support shown inFIG. 7 . - Referring to FIGS. 1 to 5, an
infusion package 10 comprises acontainer 12 and support for the container. The support comprises twosupport members 14 by means of which the container can be mounted on a rim of a drinking vessel such as a mug orcup 15 as shown inFIG. 4 . - The support elements each consist of a strip of plastics coated board and are disposed opposite one another. Each support member is notched at one of its
ends 16 to define aprojection 18. Theprojection 18 lies in the plane of the support member and projects in the lengthwise direction of the member perpendicular to theend 16. - At the
end 20 of the support members opposite theend 16, there is arecess 22. Therecesses 22 are aligned with and correspond in shape to therespective projections 18. - As described in more detail hereinbelow, the support members are sealed to one another and to the
container 12. The arrangement of the support members is such that theend 16 of one member is disposed opposite theend 20 of the other member so that the respective projections project in opposite directions. - Each support member has a score-
line 24 in the inward facing one of its major surfaces. The score-lines are disposed midway between theends ends - The container is in the form of an open-ended sack, or bag, 12. The bag comprises a web of porous heat sealable material, which is folded to produce a cross-section, which is generally W-shaped as shown in
FIG. 3 . Thelong sides 30 of the W are sealed to each other by edge seals 32 (FIG. 1 ) which extend from the upper to the lower end of the bag. The edge seals are interconnected bytransverse seals 34 running along 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 transverse seals run in parallel and are made between theinternal surfaces 36 of the central portion of the W and the opposed surfaces of thelong sides 30. The transverse seals do not seal theexternal surfaces 38 of the central portion to one another. This sealing arrangement provides the bag with an inwardly directed gusset at its lower end, which increases the volume of the bag. This can be seen inFIG. 2 which shows that the bag is wider at its lower end than at the upper end where it is joined to the support members. - The upper, open, end of the bag is sandwiched between the support members. The external surfaces of the bag at the open end are secured to the opposed inwardly facing surfaces of the
support members 14 in an arrangement which, as best seen inFIG. 4 , leaves the bag open at the upper end. Thesupport members 14 are sealed to one another at theirends lines 24. As shown inFIG. 5 , the width w of the edge seals is greater than the depth d of therecesses 22. - The
bag 12 contains an infusible material such as tea or coffee. When the infusible material is coffee, it is preferable that the package is supplied in a hermetically sealedsachet 40 as shown inFIG. 5 . The sachet may be in the form of a standard pillow pack as illustrated. The infusion package is packed in the sachet with the support members folded over so that it is disposed alongside the upper end of thebag 12. This has the advantages that the size of sachet required is reduced and the open end of the bag is effectively closed so that the coffee will not spill out in transit. - In use, the bag is removed from the sachet and the support members are folded upwardly to bring the infusion package into the condition shown in
FIG. 1 . A compressive force is applied to the ends of the support member causing the members to bow outwardly in the region of the score-lines 24. As shown inFIG. 4 , the result is that the support members adopt a diamond configuration allowing theprojections 18 to seat on the rim of adrinking vessel 15. In addition, the bowing of the support members opens the upper end of the bag and provides an opening through which water can be poured onto the coffee contained in the bag. It will be appreciated that the compressibility of the support members provides the additional advantage that the support can be manipulated to fit drinking vessels of varying diameters. - Manufacture of the support members will now be described with reference to
FIG. 6 . In a preferred arrangement, the supports are made from support members taken from twowebs - The support members are produced by making
transverse cuts 54 in the web at intervals corresponding to the desired length of the support members. The transverse cuts extend from one side of the web to the other and each defines theend 16 of one member and theend 20 of the following member so that theprojection 18 of one member is produced by the cut which also produces the recess of the next member. It will be appreciated that this arrangement allows the production of the support members without any material wastage. - The
webs cuts 54 are arranged such that the projections produced in theweb 50 point in the direction of movement of the web, whilst the projections produced in theweb 52 point in the direction opposite the direction of movement. To produce a support, a support member a support member from theweb 50 is brought into opposed relationship with a support member from theweb 52. It will be appreciated that by having the projections of the two webs pointing in opposite directions, the two support members can readily be brought into opposed relationship to produce a support having its two projections pointing in opposite directions without any complicated turning movements. It will also be appreciated that although, the webs are shown moving in an edge-to-edge relationship which would require rotation of at least one of the support members about its longitudinal axis, the webs could be cut whilst running in a face-to-face relationship so that subsequent to the cutting process, all that would be required is to move the opposed faces of the web into contact with one another. - The support members from the two webs may be secured to one another by heat sealing. Preferably, at least one side of the webs from which the support members is made is coated with a heat sealable material so that sealing process simply involves pressing the two members together and applying heat to obtain a seal. Alternatively, a hot melt adhesive may be painted onto one or both webs in a suitable pattern to produce the required arrangement of seals. A further alternative is to apply an adhesive such as a food compatible paste to one of the webs.
- The cutting process may be partial so that the respective support members of the two webs are finally separated from one another at an assembly position downstream of the cutting position.
- An alternative support for the infusion package and a method of manufacture therefor will now be described with reference to
FIGS. 7 and 8 . - Referring to
FIG. 7 , analternative support 70 for the infusion package, comprisesintegral support members 72. The support members haveprojections 74 and recesses 76 corresponding to the projections and recesses of thesupport members 72 and are made from a single web 78 (FIG. 8 ) of plastics coated board folded about itslongitudinal axis 80 so as to have a generally U-shaped cross-section. - As shown in
FIG. 8 thesupport members 72 of thesupport 70 are produced by makingtransverse cuts 82 in theweb 78 at intervals corresponding to the desired length of the support members. The transverse cuts extend from one side of the web to the other and each defines the end of onesupport 70 and the end of the following support so that the projections produced at each end of the support are produced by the cuts which also produce the recesses in the adjacent end of the neighbouring supports. Subsequent to the cutting operation, the support members are brought into an opposed relationship to define the U-section support by folding the web about itsaxis 80. The support members can then be secured to one another by sealing or gluing as described above. - It will be appreciated that the closed top of the
support 70 prevents spillage of the infusible material contained in the bag. The support may formed withperforations 84 to permit the top to be removed to allow water to be poured onto the infusible material. Alternatively, in a manufacturing process in which thesupport 70 is secured to the bag before the bag is filled with the infusible material, the perforations can be used to permit the top of the support to be removed to allow a dose of the infusible material to be dropped into the bag through the support. It will be appreciated that in such a process, a zone of weakness provided by, for example score-lines as shown inFIG. 1 , is required to permit the support members to bow outwardly in response to suitable manipulation or the application of a suitable force to produce a suitable opening through which the infusible material can pass. - It will be understood that the
support 70 can be pivoted relative to the bag in the same way as the support of theinfusion package 10.
