Definitions

  • the present invention relates to a seal for capping containers, such as bottles or the like.
  • bottles made of plastic material in particular bottles intended to contain milk, yoghurt or similar products: reclosable and non reclosable closures.
  • Crown or screw caps belong to the first type, while seals or opercula made of aluminum belong to the second type.
  • the bottle can also be provided with a screw cap to be placed over the seal, so that once the latter has been removed, the bottle can still be closed.
  • the choice of using a screw cap in addition to a seal often depends on the volume of the bottle, i.e. if the latter is not of the single-dose type.
  • bottles with a non-calibrated neck such as bottles made of HDPE (high density polyethylene), for example, it is not possible to apply sealing screw tops, as is the case, instead, for bottles made of PET.
  • This technical problem thus binds to use seals made of aluminum, which are welded to the edge of the bottle so as to ensure a perfect sealing.
  • a non-sealing cap can then be screwed to the neck of the bottle, depending on the needs.
  • opercula made of aluminum, a non-biodegradable material involve ecological problems because very often the consumer disposes of the operculum in the environment after opening the bottle. This problem is particularly felt especially in the case of single-dose bottles, the consumption of which is frequently related to use on the street.
  • the problem addressed by the present invention is the provision of a seal for containers, in particular bottles with a non-calibrated neck, which overcomes the disadvantages of known closures.
  • the present invention relates to a seal or operculum made of sterilizable plastic material which can be applied by means of welding to the edge of the neck of a container, as defined in any one of the claims from 1 to 8.
  • the invention further relates to a package of a sterile product, preferably a food, dietary, pharmaceutical, cosmetic or supplement product, as defined in claims 9-10, comprising a container having a neck ending in an edge surrounding an opening, wherein the seal or operculum of the invention is welded to said edge, and wherein said seal or operculum or parts thereof are not totally removable from said package.
  • a sterile product preferably a food, dietary, pharmaceutical, cosmetic or supplement product, as defined in claims 9-10, comprising a container having a neck ending in an edge surrounding an opening, wherein the seal or operculum of the invention is welded to said edge, and wherein said seal or operculum or parts thereof are not totally removable from said package.
  • the invention further relate to a package comprising a seal or an operculum as defined above, characterized in that it is reclosable, as well as to the respective seal or operculum.
  • numeral 1, 101 denotes a seal or operculum which does not form part of the invention.
  • the seal 1, shown in figure 1A is applied to the edge B of the opening A of a container C.
  • the opening A is placed at the upper end of the neck CL of the container C.
  • the outer surface S of the neck CL, above the finish BG, comprises, in the example shown in the figure, a thread F so as to screw a screw cap (not shown) thereto.
  • the thread can be omitted, as in the case of single-dose bottles.
  • the seal 1 is substantially discoidal in shape and comprises an edge portion 2, a partially removable central portion 3, and a connection portion 4, comprising an arc-of-circle shaped groove 5.
  • the arc-of-circle shaped groove 5 corresponds to a weakening line, having a reduced thickness (side section as in figure 1 ) with respect to the thickness of the seal 1, and forms a tear line.
  • connection portion 4 comprises a stem element 6 arranged on the same circumference as the arc-of-circle shaped groove 5 and configured to keep the central portion 3 constantly connected to the connection portion 4 and/or to the edge portion 2.
  • the stem element 6 has a side section thickness which is substantially equal to that of the seal 1.
  • the arc-of-circle shaped groove 5 has a V-shaped section.
  • connection portion 4 has a truncated-cone shape, so as to connect the edge portion 2 and the central portion 3 on different planes, in detail, the plane in which the central portion 3 lies is lower than the plane of the edge portion 2.
  • the central portion 3, arranged inside the arc-of-circle shaped groove 5, is discoidal in shape and comprises a tongue 7 to facilitate the tearing and partial removal of the central portion 3, which, as said, will however remain connected to the seal 1, and thus to the container C, by means of the stem element 6 (see figure 3 ).
  • the tongue 7 is placed on the edge 3a of the central portion 3, close to the arc-of-circle shaped groove 5 and in a diametrically opposite position with respect to the stem element 6, or at an angle of ⁇ 5° with respect thereto along the edge 3a.
  • the tongue 7 comprises a flat portion 7a and a joining portion 7b.
  • the flat portion 7a is substantially parallel to the plane in which the central portion 3 lies, and lies on a plane which is lower than or coincides with the plane in which the edge portion 2 of the seal 1 lies.
  • the joining portion 7b is preferably inclined with an angle of less than 90° with respect to the plane of the central portion 3.
  • figure 1B A different example is shown in figure 1B , where the numbering 101, 102, 103, 103a, 104, 105, 106, 107, 107a and 107b identifies elements corresponding to the same elements numbered as 1, 2, 3, 3a, 4, 5, 6, 7, 7a and 7b, respectively, in figure 1A .
  • the plane in which the central portion 103 lies is the same as that of the edge portion 102, whereby the tongue 107 protrudes above the plane of the edge portion 102.
  • Figures 4 and 5 show the seal of the invention, characterized in that it is reclosable once the seal has been broken.
  • the term "reclosable” is not meant to indicate a watertight seal, but the reclosing for an indefinite number of times without the aid of a cap.
  • This embodiment is particularly useful in the case of beverages in multi-dose containers, such as milk, fruit juices and the like, which can thus be kept, for example in the fridge, even for several days.
  • the seal 201 is substantially discoidal in shape and comprises an edge portion 202 and a partially removable central portion 203.
  • An arc-of-circle shaped groove 205 is placed between the edge portion 202 and the central portion 203.
  • the arc-of-circle shaped groove 205 corresponds to a weakening line, having a reduced thickness (side section as in figure 4 ) with respect to the thickness of the seal 201, and forms a tear line.
  • the arc-of-circle shaped groove 205 runs along an arc of circle of less than 360°, but preferably greater than 350°, so as to define a stem element 206 arranged on the same circumference as the arc-of-circle shaped groove 205, configured to keep the central portion 203 constantly connected to the edge portion 202.
  • the stem element 206 has a side section thickness which is substantially equal to that of the seal 201.
  • the arc-of-circle shaped groove 205 has a V-shaped section.
  • the plane in which the central portion 203 lies is lower than the plane of the edge portion 202.
  • the central portion 203 arranged inside the arc-of-circle shaped groove 205, comprises a lowered portion 203a and a connection portion 203b with the edge portion 202, where said connection portion 203b has a substantially cylindrical shape and rises up from the lowered portion 203a.
  • One or more annular projections 208 configured to assure against the inner surface of the neck CL of the container C are arranged on the outer surface of the connection portion 203b, thus ensuring the pressurized reclosing of the seal 201 once it has been opened. Such a pressurized reclosing is ensured by the interference between the annular projections 208 and the neck CL, due to the pliability of the material of the seal 201, which is normally flexible plastic material.
  • the lowered portion 203a comprises a tongue 207 to facilitate the tearing and partial removal of the central portion 203, which, as said, will however remain connected to the seal 201, and thus to the container C, by means of the stem element 206.
  • the tongue 207 can be ring-shaped, for example, as shown in figure 5 .
  • the tongue 207 does not protrude beyond the edge portion 202 of the seal 201, so as to remain always hidden in the cavity formed between the edge portion 202 and the lowered portion 203a.
  • the tongue 207 is placed on the edge of the lowered portion 203a, in a diametrically opposite position with respect to the stem element 206, or at an angle of ⁇ 5° with respect thereto.
  • the seal or operculum 1, 101, 201 is made of plastic material, preferably of the same material as the container C.
  • the seal 1, 101, 201 will also preferably be made of HDPE.
  • the seal or operculum 1, 101, 201 is weldable to the edge B of the container C by means of the edge portion 2, 102, 202.
  • the welding systems normally used for welding parts made of plastic material could be used, without the aid of intermediate materials, such as mastics or glues.
  • an ultrasound welding using for example suitable sonotrodes mounted to traditional capping machines replacing the capping heads could be used.
  • the seal or operculum 1, 101 can be sterilized in the same system used for sterilizing the container C.
  • the seal 1, 101, 201 is welded to the edge B of the container C, while the central portion 3, 103, 203 is always associated with the seal due to the stem element 6, 106, 206. This allows the seal not to be disposed of in the environment once the package has been opened.
  • the possibility of manufacturing the seal 1, 101, 201 of the same material as the container C makes the production, sterilization and welding thereof particularly inexpensive and simple to produce.
  • the seal 1, 101, 201 has the advantage of being applied to non-calibrated necks, such as those made of HDPE, for example, making the seal of the invention similar to the opercula made of aluminum, from which it differs, however, due to a lower cost and easier sterilization and welding.
  • the seal 1, 101, 201 of the invention can be opened more easily due to the presence of the tongue 7, 207.
  • seal 1, 101 does not exclude the further application of a screw cap, which will be placed thereon.
