Definitions

  • the present disclosure relates to the field of straws and filters employed in straws.
  • filters are used to separate solid particles from a fluid flowing through a conduit.
  • the fluid is introduced in the conduit under pressure, and is allowed to pass through a plurality of pores of the filter so as to trap the solid particulates present in the fluid.
  • the conventional filters face a problem of clogged pores, wherein large size solid particles get trapped within the smaller sized pores, thereby clogging the pores and blocking the flow of the fluid downstream of the filter.
  • the clogged pores lead to decrease in flow rate of the fluid.
  • the filters are required to be cleaned frequently which is time consuming. Additionally, continuous clogging of the pores may even erode the pores and damage the filter, which is not desired. Therefore, there is felt a need for a filter for conduits that overcomes the aforementioned drawbacks.
  • Prepackaged beverages like cold drinks, flavored milk, and the like are generally not very hygienic. These prepackaged beverages are typically packaged within TETRA-PACK cartons, which might have been extensively handled previously during packaging, transportation, and stacking on shelves or storing in refrigerators. A consumer cannot drink the beverage directly from the carton, as the carton is unclean due to previous extensive handling. To address this issue, straws are often used. However, using straws also does not seem to be a good option since the straws are also extensively handled before being placed on the shelves. Furthermore, the retailer is not normally able to charge an additional price for straws, which compromises the profit margin of the retailer.
  • US Patent Application US2010/0159075 discloses a receptacle that includes an elongate tubular body, a plurality of pellets disposed within the body, and filtration means disposed at or adjacent to each end of the tubular body to retain the pellets substantially within the body.
  • the orientation and structure of filtration means and the size of the pellets results in increasing sucking pressure required for sipping through end of tubular body.
  • the relatively large size pellets results in an incomplete dissolution and waste of pellet material.
  • the transfer of flavour carrier fluid is uneven. This is not desired.
  • An object of the present disclosure is to provide a filter for conduits that prevents the clogging of slits. Another object of the present disclosure is to provide aero dynamicity to the fluid flowing therethrough.
  • Yet another object of the present disclosure is to provide a flavour infusing straw that provides a mess-free option for enjoying flavoured drinks.
  • Still another object of the present disclosure is to provide a flavour infusing straw that facilitates optimal mixing of the flavour from the flavour cartridge with the edible liquid.
  • the present disclosure envisages a filter for conduits.
  • the filter is configured to be removably fitted within the conduit.
  • the filter is defined by a sleeve type body, which is open at one end and partially closed at another end.
  • the sleeve type body has an annular opening defined at the open end, a chamfered face with an outwardly directed face having an arcuate extremity at the partially closed end, and a plurality of slits configured on the chamfered face.
  • the filter is disposed within the conduit such that the chamfered face is disposed downstream of the fluid flow. The chamfered face facilitates aero dynamic flow to the fluid flowing through the sleeve type body.
  • the filter is disposed within the conduit such that the chamfered face is disposed upstream of the fluid flow and the arcuate extremity of the chamfered face facilitates disintegration of solid particles contained within the fluid into finer particles.
  • the shape of the sleeve type body is complementary to shape of the conduit.
  • At least some of the plurality of slits has arcuate shapes. In another embodiment, at least some of the plurality of slits is elliptical arcs.
  • an angle of the chamfered face formed with respect to a base of the sleeve type body is directly proportional to the diameter of the sleeve type body of the filter.
  • the plurality of slits have a width ranging from 0.8 mm to 1 mm.
  • the present disclosure further envisages a flavour infusing straw.
  • the flavour infusing straw comprises a hollow elongate body, a pair of wedge type stoppers configured to be inserted at the operative ends of the body.
  • the pair of wedge type stoppers has a solid chamfered face defining slit type openings and a knife edge.
  • the flavour cartridge is placed operatively between the pair of wedge type stoppers within the hollow elongate body.
  • the wedge type stoppers have cylindrical shape.
  • the pair of wedge type stoppers is configured to facilitate a uniform transverse flow of an edible liquid through the flavour cartridge.
  • the flavour cartridge has a plurality of flavour beads.
  • the plurality of flavour beads has an average diameter ranging from 20% to 22% of the internal diameter of the hollow elongate body.
  • At least some of the slit type openings are arcuate. In another embodiment, at least some of the slit type openings are elliptical arcs.
  • the knife edge is provided along the edges of the solid chamfered face. In an embodiment, the knife edge is provided at the operative lower tip of the solid chamfered face.
  • the knife edge formation at the distal end has a solid region extending into the pair of wedge type stoppers.
  • the hollow elongate body has folding portions configured at the operative ends thereby preventing the wedge type stoppers from sliding out of the hollow elongate body.
  • each of the flavour beads is having a plurality of concentric layer of the flavours.
  • the flavour of the flavour beads is selected from the group consisting of sweeteners, flavouring agents, coloring agents, viscosity modifiers, vitamin supplements, minerals, herbal extracts, energy enhancing additives and any combinations thereof.

  • angle of the chamfered face 104 with respect to a base 100A of the sleeve type body 102 is directly proportional to the diameter of the sleeve type body 102. Further, a decrease in the angle of the chamfered face 104 with respect to the base 100A increases the surface area of the chamfered face 104, thereby facilitating easy passage of fluid through the sleeve type body 102. Also, an increase in the length of the base 100A of the sleeve type body 102 increases the surface area of the chamfered face 104, thereby facilitating easy passage of fluid through the sleeve type body 102.

Le filtre (100) comprend un corps du type manchon (102). Le corps du type manchon (102) est ouvert à une extrémité et partiellement fermé à l'autre extrémité. Le corps du type manchon (102) possède une ouverture annulaire (102 A) délimitée au niveau de l'extrémité ouverte. Une face chanfreinée (104) est pourvue d'une face dirigée vers l'extérieur. La face dirigée vers l'extérieur est pourvue d'une extrémité arquée (106) au niveau de l'extrémité partiellement fermée. Une pluralité de fentes (104 A) sont configurées sur la face chanfreinée solide (104). La pluralité de fentes (104 A) sont configurées de sorte à faciliter le filtrage d'un fluide s'écoulant à travers celles-ci. Le filtre (100) améliore le débit de fluide en aval du filtre (100). La présente invention concerne également une paille d'infusion d'arôme qui utilise le filtre (100).
