Definitions

  • This invention relates to a single-lobe or single-chamber filter bag for infusion products, such as tea, coffee, camomile and the like.
  • the current market offers many different kinds of filter bags (or tea bags) for infusing the above mentioned products in water.
  • filter bags The wide range of filter bags currently available is the result of the increasingly widespread use and popularity of filter bags among consumers, both in the home and in public places, which has led to a growing demand, especially from product distributors, for diversification of filter bag designs with a view to obtaining filter bags with improved properties in terms of product containment, ease of exchange with the liquid during infusion, shelf life, ease of final packaging, and so on.
  • the two main designs currently used are the traditional single-lobe bags (usually with tie string and tag) and the now well-established two-lobe bags (also with tie string and tag, with or without individual overwrapper), whose characteristic feature is the larger surface area in contact with the liquid, which allows optimum extraction of the flavour from the infusion product).
  • the methods of closing the bag and simultaneously applying the string and tag have been diversified according to production needs and, in some countries, legislative requirements: for example, the tie string, tag and filter bag may be closed and joined by a metal staple, by gluing, by a heat sealable “accessory stamp”, by forming a stitch with the tie string itself or by using an adhesive tag.
  • the product is more constrained within the bag, with less room to expand during infusion, which means poorer quality infusions and longer infusion times;
  • the filter bags are more difficult to pack on account of possible movements during positioning.
  • the Applicant has created a single-lobe filter bag that overcomes the above mentioned disadvantages and whose structure, besides having the well-known features of customary single-lobe filter bags, is such as to provide a “stiffer” configuration that meets market requirements and, at the same time, improves the overall quality of the infusion and of the filter bag itself.
  • the invention achieves this purpose by providing a single-lobe filter bag, in particular a single-lobe filter bag for infusion products comprising the technical characteristics described in one or more of the appended claims.
  • FIGS. 1 to 4 illustrate a first embodiment of a single-lobe filter bag for infusion products according to the invention in perspective, front, side, and bottom plan views, respectively;
  • FIG. 5 is a front view of a variant of the filter bag of FIGS. 1 to 4 ;
  • FIGS. 6 to 10 illustrate a second embodiment of a single-lobe filter bag for infusion products according to the invention in perspective, front, right-hand side, left-hand side and bottom plan views, respectively;
  • FIG. 11 is a perspective view showing a variant of the filter bag of FIGS. 6 to 10 ;
  • FIGS. 12 to 16 illustrate a third embodiment of a single-lobe filter bag for infusion products according to the invention in perspective, front face, rear face, side, and bottom plan views, respectively;
  • FIGS. 17 to 20 are perspective, front, side, and bottom plan views, respectively, showing a detail of a variant of the third embodiment of the single-lobe filter bag of FIGS. 12 to 16 ;
  • FIG. 21 is a perspective view illustrating a variant of the filter bag of FIGS. 12 to 16 ;
  • FIGS. 22 to 26 illustrate a fourth single-lobe bag in perspective, front face, side, rear face and top plan views, respectively;
  • FIGS. 27 to 31 are, respectively, perspective, front face, side, rear face and top plan views illustrating a variant of the embodiment of the filter bag of FIGS. 22 to 26 .
  • the single-lobe or single-chamber filter bag is used for infusion products, such as tea, coffee, camomile and the like.
  • the filter bag labelled 1 in its entirety, essentially comprises a length 2 of filter material forming a chamber 3 containing a charge 4 of the infusion product.
  • the length 2 of filter material has a quadrangular shape defined by:
  • the two sides 8 , 9 connecting the first and second edges 5 and 7 are at least partly folded onto each other to form a fold towards the inside of the chamber 3 ;
  • the second bottom end 7 of the filter bag 1 is closed by a second join S 2 designed to form a stiff flat bottom surface 11 of the filter bag 1 such as to define a stable base, with a substantially triangular cross section, for supporting the filter bag 1 .
  • the second end 7 comprises two second edges 7 a and 7 b folded one over the other and joined along the second bottom end 7 to directly define the bottom supporting base 11 .
  • the second end 7 comprises two second edges 7 a and 7 b folded one over the other and joined at the bottom ends 8 a , 8 b and 9 a , 9 b of the sides 8 and 9 in such a way as to obtain a continuous bottom surface 11 defining the bottom supporting base.
  • each of the two second edges 7 a and 7 b closer to the sides 8 and 9 are partially folded towards the inside of the chamber 3 to form a bevelled shape and are flattened on the corresponding area of the other edge 7 a or 7 b in such a way as to create the stiff supporting base 11 at the second end 7 .
  • the second edges 7 a and 7 b define a central extension of the second bottom end 7 .
  • the second edges 7 a and 7 b are folded face to face onto each other and joined in such a way as to form a tab 12 protruding from the bottom supporting base 11 that is elastically compliant in such a way as to be folded onto the bottom base 11 to increase its stiffness.
  • the tab 12 may be folded and joined stably by a seal S 4 to the bottom supporting base 11 , thus forming a larger, stiff longitudinal area (see FIGS. 17 to 20 ).
  • each of the second edges 7 a and 7 b are folded towards the first end 5 , which is placed over the respective end of the other edge 7 a or 7 b and at the respective bottom ends 8 a , 8 b and 9 a , 9 b of the connecting sides 8 and 9 (initially open) of the length 2 in such a way as to form a bevelled shape.
  • Each pair of ends of the second edges 7 a and 7 b is reciprocally joined by a seal S 2 at the respective bottom areas of the connecting sides 8 and 9 : this creates a stiff lateral area of the length 2 in order to form wide supporting shoulders for the closed bottom supporting base 11 of the filter bag 1 .
  • the seal S 2 is simultaneously made also on the substantially central area of each side 8 , 9 in order to also join the latter which, as stated, are initially open, in the configuration in which they are folded towards the inside of the chamber 3 .
  • the filter bag 1 may be equipped, on the length 2 , with a string 13 joined by sealing one end of it to the length 2 itself and the other end to a tag 14 which is in turn removably associated with the length 2 of filter material: this allows correct handling of the filter bag 1 during infusion.
  • the length 2 of filter material may consist of filter paper or biodegradable material (such as, by way of non limiting example, maize starch) or a non-biodegradable plastic material (such as polyethylene).
  • the joins on the length 2 of filter material may consist of a first and a second heat seal S 1 and S 2 , that is to say, made by heat sealing.
  • the two joins may consist of a first and a second seal S 1 and S 2 made using a suitable glue.
  • the two joins on the length 2 may consist of a first and a second ultrasound seal S 1 and S 2 .
  • the corners 5 a and 5 b of the first top end 5 of the length 2 are bevelled symmetrically according to an angle ⁇ (see FIGS. 5 , 11 and 21 ).
  • the tubular length 2 having an initially open tubular shape, may, at least in the first two embodiments described above, have a central join for closing the tube and consisting of a third join or seal S 3 .
  • FIGS. 22 to 26 and 27 to 31 illustrate another two alternative embodiments of the filter bag 1 whose structural configuration is based on that of the embodiment illustrated in FIGS. 12 to 16 .
  • the length 2 of filter material is provided with a string 13 joined, at one end, to the length 2 itself by a knot A 1 and, at the other end, to the tag 14 by a knot A 2 , the string 13 being looped around the length 2 and also around the elastically compliant tab 12 protruding from the bottom supporting base 11 .
  • the tag 14 may also be removably attached, for example by sealing, to the length 2 of filter material.
  • the tag 14 may have a slit 14 f made at the top of it for engaging an end portion P of the string 13 knotted to the length 2 of filter material in such a way as to hold it against the length 2 .
  • the tag 14 is positioned at the top 5 of the length 2 (where the closing seal S 1 is located) and protrudes partially from the length 2 itself.
  • the filter bag 1 illustrated in FIGS. 27 to 31 differs mainly in that corners 5 a and 5 b of the first, top end 5 of the length 2 are bevelled symmetrically according to an angle ⁇ .
  • a filter bag made as described above therefore achieves the above mentioned purposes thanks to the special forms imparted to the connecting sides and to the bottom edges that close the length of filter material in such a way as to create a flat stiff base that provides: a chamber 3 with a constant volume not only before use, housing the product comfortably and stably, and allowing the filter bag to stand erect on a supporting surface, but also during infusion, allowing the product to move and expand optimally within the chamber, thus guaranteeing an infusion of excellent quality and reduced infusion times.
