Definitions

  • the present invention relates to a reservoir cap.
  • Such a reservoir cap is provided with a cutter inside which a hollow sleeve or cup-shaped element made of a material that absorbs moisture is inserted.
  • the object of the present invention is to provide a reservoir cap which is improved with respect to those described in the prior art.
  • a reservoir cap according to the invention improves the protection against moisture of the product present in the reservoir.
  • a reservoir cap according to the present invention improves the emptying of the product with respect to the caps described in EP2704962-A1.
  • a reservoir cap according to the present invention allows an increase in the volumetric capacity of the reservoir with respect to reservoirs with “sleeve” or “cup-shaped” moisture absorbing material inserted inside the cutter.
  • FIG. 1 is an axial section view of a reservoir cap according to the present invention, in a first operative configuration, when accommodated on a container;
  • FIG. 2 is an axial section view of the reservoir cap of FIG. 1 , shown in a second operative configuration
  • FIGS. 3 and 3A are an axial and a lateral section, respectively, of a variant of a detail of the cap in FIG. 1 ;
  • FIGS. 4 and 4A are an axial and a lateral section, respectively, of another variant of the detail in FIG. 3 ;
  • FIGS. 5 and 6 are lateral sections of further variants of the detail in FIG. 3 ;
  • FIGS. 7 and 7A are a plan view and an axial section, respectively, of yet another variant of the detail in FIG. 3 ;
  • FIGS. 8 and 8A are a plan view and an axial section, respectively, of a further variant of the detail in FIG. 3 .
  • a reservoir cap is shown, globally denoted by reference numeral 1.
  • the reservoir cap 1 is configured to be coupled to a neck 4 A of a container 4 at its opening 5 .
  • the cap 1 comprises a body 3 which defines a cup-shaped portion 9 closed at its bottom by a breakable wall 31 .
  • the body 3 comprises at least one sealing element 32 with said neck 4 A, which can be formed by an outer surface of the cup-shaped portion 9 , of a diameter such as to couple with slight interference and in a sealed manner with the inner part of the neck of the container 4 .
  • the body 3 can further be provided with a shoulder 61 intended to abut with a front surface of the opening 4 A, so as to form a stop for insertion of the body 3 into the opening 4 A.
  • the cap 1 comprises a cutter 2 , which may have a mushroom shape. It may be provided with a head 20 from which extends a cylindrical surface 21 which is internally hollow that, when coupled to the cup-shaped portion 9 , forms together with at least a part of such a cup-shaped portion 9 a reservoir S in which a product 10 can be contained.
  • the product 10 may be a powder containing one or more of: lactic ferments, bacteria, vitamins, food supplements for both therapeutic and dietary use.
  • the cutter 2 is sliding in a sealed manner inside the cup-shaped portion 9 .
  • a larger diameter area 63 may be provided (for example close to the head 20 ) intended to couple with slight interference and in a sealed manner with the inner surface of the cup-shaped body.
  • the interference between the cutter and the cup-shaped body is in any case such as to allow an axial sliding of the cutter with respect to the cup-shaped body, when the first is loaded by a predetermined pressure.
  • the cutter and specifically a free end of the cylindrical surface 21 thereof, defines a cutting surface 24 of the breakable wall 31 .
  • the free end 22 of the cutter 2 lies in a plane angled relative to a longitudinal axis A of the cutter, so as to form a ‘blade’ which facilitates the rupture of the bottom by concentrating the pressure in a single portion of the free end.
  • the cup-shaped portion 9 is configured so that when the cap 1 is placed on the container 4 and the product is in the reservoir S, the cutter 2 , pushed with force against the breakable wall 31 thereof, at least partially separates the breakable wall from the cup-shaped portion 9 which causes the introduction of the product by fall into the container 4 (see FIG. 2 ).
  • a screw mounting lid 40 can be provided.
  • the lid can be advantageously screw mounted on a thread provided on the container 4 , near the mouth 4 A thereof.
  • the body 3 can be totally enclosed between the container 4 and the lid.
  • sealing means adapted to prevent an air leakage between the body 3 and the lid 40 .
  • such sealing means may comprise a lip 70 protruding from the body 3 , which rests on the inner surface of the lid 40 , above a threaded portion thereof.
  • At least a part of the outer surface of the cutter is made of said thermoplastic material that absorbs moisture.
  • the moisture-absorbing material minimises the entry of moisture from the external environment into the reservoir.
  • the presence of the lid 40 is particularly advantageous, both in the presence of said sealing means 70 and in their absence.
  • the part of the outer surface of the cutter made of moisture absorbing material is in communication with the chamber 80 formed between the lid 40 and the body 3 (or more generally with the container 4 ), it is possible to remove moisture from chamber 80 , thus improving the product preservation.
  • the part of the outer surface of the cutter made of moisture absorbing material is instead inside the cup (and is specifically in that area between a seal between the cup and the cutter and the breakable bottom 31 ), it can absorb any moisture originating from the liquid L of the container that transpires through the cup-shaped body (and possibly through the collapsible bottom thereof).
  • At least a part of the free end 22 of the cutter is made of a thermoplastic material that absorbs moisture.
  • the moisture absorbing material is substantially rigid, and in any case more rigid than the remaining thermoplastic material of which the cutter is usually made, use in such a position improves the ‘cutting’ of the collapsible bottom.
  • the cutter 2 is made in one piece by moulding of plastic material, and is entirely made of said thermoplastic material that absorbs moisture.
  • An even more advantageous embodiment may provide that, from the head 20 of the cutter 2 , internally to the cylindrical surface 21 , an elongated element 50 protrudes, made of a thermoplastic material that absorbs moisture.
  • the elongated element can be configured to form a hollow space I between its surface and that part of the cylindrical surface 21 facing the elongated element 50 .
  • the elongated element 50 may have a height H (FIG. 1 ) so as to be drowned in the product S, when the product is inside the reservoir.
  • the elongated element 50 may be free from cavities where the product can be stuck.
  • the cutter and the elongated element can be made in one piece of moisture absorbing material.
  • the elongated element may preferably have a tapered shape, which facilitates the falling of the powder once the bottom 31 has been broken.
  • the elongated element 50 can have a conical or frustoconical configuration, or a pyramid or a truncated pyramid configuration, with a polygonal base (for example, square or hexagonal).
  • the cutter 2 and the elongated element 50 can be made in two different pieces (for example by co-moulding) or in one piece.
  • the cutter and the elongated element are in one piece of moisture absorbing material.
  • FIGS. 3 and 3A shows a cutter made entirely of moisture absorbing material, but without an elongated element 50 .
  • FIGS. 4 and 4A shows the cutter in FIG. 3 , where, at a smaller height position of the cylindrical surface 21 , there is a notch 60 adapted to prevent a complete rupture of said breakable wall 31 .
  • the notch 60 can be made on any cutter described in the present text, and also on already known cutters, also without moisture absorbing material.
  • the cutter in FIG. 5 is made by co-moulding.
  • the head 20 of the cutter and the elongated element 50 are made of moisture absorbing material.
  • the cylindrical portion 21 is instead made of standard plastic material, which does not absorb moisture.
  • FIG. 6 provides for a cutter in which the head 20 and the cylindrical portion are made of conventional plastic material, whereas only elongated element 50 is made of a material that absorbs moisture.
  • a part 50 A of the elongated element 50 may protrude through an opening 90 so as to face the outer surface of the cutter.
  • outer surface of the cutter is the one external to the cavity defined by the cylindrical portion 21 (and by the elongated element, if present).
  • Such a cutter can be advantageously made by co-moulding.
  • FIG. 7 and FIG. 7A show a cutter in which a part 21 B of the cylindrical portion, the head 20 and the elongated element 50 are made of moisture absorbing material, whereas the remaining part 21 A of the cylindrical portion 21 is made of conventional plastic material.
  • the portion 21 A of the cylindrical portion is a vertical band (which may be even smaller than the one shown) of conventional plastic material.
  • the moulding thereof (as well as of the other embodiments described in the present text) can be carried out by bi-injection.
  • FIGS. 8 and 8A Still another embodiment is shown in FIGS. 8 and 8A .
  • Such an embodiment differs from the one described above because also a part 20 A of the head is made of conventional plastic material, while a part thereof (the 20 B) is made of moisture absorbing plastic material.
  • ‘conventional plastic material’ of which the cutter is manufactured refers to one or more of those selected from the following group: PE-PA-PP.
  • the body 3 can be made of one or more of the following plastic materials: PE-PP-SEBS.
  • the cap 40 on the other hand which can be provided with a seal, may be made of one or more of the following plastic materials: PE-PP.
  • an absorbing polymer preferably a water-absorbing or hygroscopic polymer which can be moulded with conventional techniques, can be used as thermoplastic material that absorbs moisture.
  • the water-absorbing or hygroscopic polymer at room temperature, is in the solid state and has physical characteristics comparable or similar to the conventional plastics with which the other parts of the cutter are made. For example, it can have a hardness comparable to (or even greater than) PE-PA-PP etc. in the same environmental conditions.
  • the moisture absorbing polymer may be a plastic compound polymer.
