Definitions

  • the present invention relates to a compact fast-opening cap and a cap and mouthpiece assembly for a container.
  • caps For the closing of liquid containers, caps can generally be provided which are arranged on the mouthpiece of the container and have a normal tamper-proof ring to which a protective cover is attached.
  • Some of these caps are snap-arranged on the mouthpiece of the container and create the required seal thanks to the presence of a complementary projection and recess produced on the mouthpiece of the container and inside a protective cover, respectively.
  • caps are screwed onto a mouthpiece of the container and the cover must be unscrewed from the mouthpiece to gain access to the contents.
  • the cover of the cap can be rotated for opening and closing around a hinge arrangement formed between the tamper-proof ring and the cover that prevents the cover from becoming dispersed in the environment, once removed.
  • caps have an extremely small encumbrance and are generally used in containers for milk, water, soft drinks, etc. which at the most have internal pressures of one bar. They are not suitable however for carbonated water at two-three bars or other pressurized liquids.
  • frangible bridges When broken, the frangible bridges naturally reveal the first opening and exert a usual anti-tampering action on the internal contents of the container.
  • the hinge arrangement generally formed next to the protective cover and the mouthpiece of the container limits the access space to the mouth of the container to a minimum, if one should or wish to drink.
  • this type of hinge arrangement creates a certain recall elasticity between the cover and the ring which, as already mentioned, greatly hinders pouring or access to the contents. And this causes an obstacle and inconvenience for the use of a container equipped with this type of cap.
  • the general objective of the present invention is to provide a compact fast-opening cap and a cap and mouthpiece assembly for a container which solves the problems associated with the prior art indicated above.
  • a further objective is to provide a compact fast-opening cap and a cap and mouthpiece assembly for a container wherein a rapid opening of the cover is obtained with respect to the mouthpiece in the presence of a threading that constrains them together.
  • Another objective of the present invention is to provide a compact fast-opening cap and a cap and mouthpiece assembly for a container which provides for an opening blockage of the protective cover, once rotated for opening, which overcomes the drawbacks of the known art maintaining the position.
  • Yet another objective of the present invention is to provide a compact fast-opening cap and a cap and mouthpiece assembly for a container capable of solving the above-mentioned drawbacks of the prior art in an extremely simple, economical and particularly functional way.
  • a further objective of the present invention is to provide a compact fast-opening cap and a cap and mouthpiece assembly for a container which allows it to be rapidly opened and allows easy access to the mouthpiece of the container and wherein the cover is kept stably open.
  • an objective of the present invention is to provide a cap for a container that can be produced by moulding HDPE whereas the mouthpiece is made of PET or an equivalent material.
  • an embodiment is shown of a compact fast-opening cap and a cap and mouthpiece assembly for a container, produced according to the present invention.
  • a compact fast-opening cap according to the invention is indicated as a whole with 11 and essentially comprises a base ring 12, to prevent its separation from a mouthpiece 13 forming part of or applicable to a container, and protective cover 14 for opening and closing the mouthpiece 13 of the container.
  • This type of cap 11 can be produced in a single piece by moulding plastic material, more particularly made of HDPE, whereas the mouthpiece is made of PET.
  • the cover 14 essentially of an inverted cup shape, has a flat upper closing wall 15 and a knurled cylindrical side wall 16. Furthermore, from the upper flat wall 15 inside the cover 14, a collar or annular element 17 with a smaller diameter than the cover extends towards the inside of the cap, coaxial to it and suitable for engaging in an internal wall 18 of the mouthpiece 13 of the container. This arrangement favours and creates an effective seal for the liquid contained in the container.
  • a series of frangible bridges 19 connects a lower edge 20 of the cover 14 with an upper edge 21 of the base ring 12.
  • This substantially cylindrical base ring 12 has an annular rib 22 protruding inwardly for engagement beneath a perimetric annular rib 25 protruding outwardly from an external side surface of the mouthpiece 13 of the container.
  • Said cap 11 has a hinge arrangement 26, in a corresponding slot or side notch 24, formed mainly in the cover 14, which makes the cover 14 and the base ring 12 integral with each other, but rotatable with respect to each other as will be seen hereunder.
  • This hinge arrangement 26 comprises a pair of spaced flat, flexible and foldable strips or bridges 27 which connect the cover 14 and the base ring 12. According to the present invention, the positioning of an enlarged outward extension 29 is also provided specifically in the middle. This enlarged extension 29 is an integral part of a lower end of the shaped side wall 16 of the cap 14 near the lower edge 20, which faces the base ring 12.
  • Said extension 29 enlarged outwardly is shaped and has facets 33 such as to create a cam effect which, when the cover 14 rotates for opening, increases the engagement of the cover with said perimetric rib 25 of the mouth 13.
  • This engagement occurs when the extension 29, on entering into engagement with the mouthpiece 13 when the cover 14 rotates from a closed position to an open position, causes a stable positioning between the parts and consequently a stable positioning of the cover in an open position.
  • the cap according to the present invention also provides that a multi-thread or multi-start thread 23 be provided inside a side wall 16 of the cover 14, which is suitable for being coupled with a series of threads 28 formed on an external wall of the mouthpiece 13.
  • twelve sections of thread are provided inside the side wall 16 of the cover 14, to form the multi-thread or twelve-start thread 23.
  • the mouthpiece 13 provides on its external side wall, six sections of thread 28 to create an arrangement such as to be easily and correctly coupled with the twelve-start thread 23 inside the cover 14.
  • This arrangement provides a rapid opening between the parts.
  • cover 14 is made of a particularly thin material and in its internal wall it provides a reinforcing and strengthening web 30.
  • the figures also show how, on one side, the cover 14 provides two recessed seats 31 arranged on opposite sides near the lower edge 20 and, on the other side, the upper edge 21 of the base ring 12 has two teeth or shaped extensions 32, also arranged on opposite sides.
  • Figures 13 and 14 show how the hinge arrangement 26 allows the cover 14 to be rotated by almost 180° with respect to the closed position ( figures 1 and 10 ) thanks to the presence of the hinge arrangement 26 which allows this rotation.
  • This arrangement achieves a fast opening between the parts.
  • two teeth 32 have been provided, which engage beneath the rib 25, once the cover 14 is rotated open around the hinge 26, and block any possibility of rotation between the parts around the axis Y.
  • the cap is very small in size, which makes it suitable for specific applications where spaces are limited.
  • a cap thus produced for example in containers for fresh milk or non-carbonated drinks, reduces its weight, i.e. that of the container or mouthpiece.
  • the product therefore uses less HDPE and has a lighter weight, without anything being dispersed in the environment as the cap remains attached to the container or bottle.
