Definitions

  • the present invention relates to a sealing device of the type normally used as caps for sealing bottles or containers, of the type containing fluids such as water, energy drinks or soft drinks in the interior thereof, which is applicable to the food and food preservation industry.
  • this sealing device for bottles or containers is to extend the useful life of the cap itself, due to the cyclicity of the aperture and closure actions of the lid of each cap, as well as guaranteeing the security of small children against used bottles, where breakage of the cap can give rise to accidental swallowing, entailing serious health risks; and which additionally allows definition of a cap having a different outer appearance to the other caps known in the state of the art; with a sealing device that is quickly formed, simple and inexpensive.
  • a cap for bottles preferably containing oil
  • a cap formed from a pouring element and a cap that comprises, on its upper part, a lid having a fold-back hinge; said hinge is formed from the plastic material cap itself, but wherein said cap has a section that is gradually weakened by the repeated number of times it is opened and closed and which, on being made of plastic material, implies that the cyclicity of such actions causes breakage or cracking of the lid, with the previously described risks.
  • the present invention relates to a sealing device for bottles or containers, which improves the resistance of the cap lid while in turn shortening forming time and simplifying the mould wherein the cap object of the invention is manufactured, as well as giving the unit a personalisable and distinctive design by means of a simple sealing device which allows adaptation to any bottle or container currently available on the market.
  • the sealing device for bottles or containers proposed by the invention comprises:
  • an insert made from a more flexible material than that of the cap is over-injected on the cap. This insert joins the body to the lid and forms a hinge area.
  • This hinge area has greater resistance and flexibility to endure the flexions, torsions and tractions to which it will be subjected during the useful life thereof.
  • Over-injection is also aimed at obtaining an outer design different to that currently known in the state of the art, as the combination of materials allows combination of different visual aspects (different colour combinations in the exterior) and even superficial aspects (varying roughness or outer finish) between the more flexible and less flexible material.
  • This solution avoids the use of a tear off and disposable seal, due to the fact that the lid, as of the first cut made in the perimeter of the cap and, logically, without being disposed in the hinge area, can be opened and folded back with relative ease; additionally, the plurality of first connection points are disposed in the area where said first cut is made, in such a manner that they are in charge of keeping the lid joined to the body of the cap and, as mentioned earlier, are disposed in the interior of the cap without being visible from the exterior by the user.
  • These first connection points are formed during the cap moulding phase in a simple and efficient manner and, after partial peripheral severing of the cap, said connection points are not severed, but must rather be broken by the user in order to open the cap.
  • the cap comprising a second peripheral cut defining the aperture area of the cap in relation to the neck of the bottle and which separates the body from the anchor seal is also envisaged.
  • the possibility of disposing the hinge at a distance from the centre of the lower cap at the distance from the perimeter thereof for the first cut is envisaged, in such a manner that the machine tool in charge of making that first cut does so in a previously defined cutting radius which does not come into contact with the hinge, due to which it is the only area where said first cut is not made and prevents the hinge, on tearing the lid, from also being torn, improving subsequent closure thereof.
  • the machine tool is in charge of cutting the entire perimeter on not existing any hinge in that lower part of the cap object of the invention.
  • cuts are technically imperceptible to the human eye, giving rise to a clean outer appearance of the cap suitable for introducing advertising or informative messages for the user along the perimeter of said cap; and where additionally there is no physical separation of the cut material prior to being torn by the user.
  • aperture force increases with respect to the possibility disclosed in earlier patents relative to the tear off and disposable seal, due to which the possibility of the lid comprising a ridge suitable for facilitating the aperture operation thereof is envisaged, in such a manner that the user places one of his/her fingers under said ridge and pushes the lid, severing it along the previously described first cut.
  • the possibility of the cap comprising at least one vertical groove disposed on the lid next to the ridge is envisaged; where said, at least one, vertical groove may break at the time of aperture of said lid by way of a weakened area of the cap; i.e. the thickness or contact area between the vertical groove and the cap is small, sufficient for the vertical groove to crack and for the user to visually verify, upon opening the cap, that the lid has not been opened beforehand; i.e. it acts by way of a warning mechanism, alerting of aperture prior to the purchase of the bottle or container by the user.
  • the lid comprising a ring-shaped portion by way of an obturator, disposed towards the neck of the bottle and inside the lid, is envisaged; wherein said ring-shaped portion is introduced into the outflow orifice of the teat when the lid is shut, ensuring tightness of the unit, and wherein the outflow orifice may be introduced into the ring-shaped portion of the lid at high pressure, in accordance with the preferred design chosen by the manufacturer.
  • the teat that forms part of this invention comprises a circumferential housing which allows introduction of the neck of the bottle at high pressure and a circumferential outer projection which interlocks with the first inner projection of the cap body.
  • the hinge comprising at least one tensioning element suitable for keeping the lid in an aperture position in relation to the body is envisaged, in such a manner that the hinge has its own tension and the lid is retained in the aperture position, facilitating the action of drinking for the user. Said retention can be achieved through a combination of thicknesses in different areas of the hinge.
  • the sealing device for bottles and containers proposed by the invention constitutes an advance in the sealing devices used to date and solves the previously expounded problems in an entirely satisfactory manner, improving the flexibility and resistance of the cap hinge and simplifying design and forming thereof, as well as giving it a unique and differentiating outer design with respect to the other caps of the state of the art.
  • FIG. 1 shows a perspective view of the sealing device object of the invention
  • FIG. 2 shows a cross-sectional view of the sealing device object of the invention, open
  • FIG. 3 shows a cross-sectional view of the sealing device object of the invention closed, wherein the neck of the bottle is coupled to the teat and cap body.
  • FIG. 4 shows a cross-sectional view of the sealing device object of the invention closed, without coupling to the neck of the bottle;
  • FIG. 5 shows a perspective view of the sealing device object of the invention, from the hinge area.
  • the device of the invention presents an insert ( 4 ) which is over-injected on the cap ( 3 ) for forming a hinge area ( 5 ) that keeps the body ( 3 a ) and lid ( 3 b ) joined together once the cap ( 3 ) has been opened.
  • This insert ( 4 ) is made from a more flexible material than that of the cap ( 3 ).
  • This hinge area ( 5 ) has greater resistance and flexibility for enduring the flexions, torsions and tractions to which it will be subjected during its useful life.
  • the insert ( 4 ) may comprise a special polypropylene based-material which will give the hinge area ( 5 ) resistance and flexibility.
  • the cap ( 3 ) may basically contain polypropylene or polyethylene, materials which are frequently found in caps.
  • the cap ( 3 ) comprises a first cut ( 6 ) which defines the fold-back and aperture area of the lid ( 3 b ) in relation to the body ( 3 a ) and which encompasses the entire perimeter of the cap ( 3 ), with the exception of the hinge area ( 5 ).
  • first connection points ( 10 ) Disposed on the area of this first cut ( 6 ) are a plurality of first connection points ( 10 ) formed in the inner wall of the cap ( 3 ), which keep the lid ( 3 b ) and body ( 3 a ) joined together until aperture thereof by folding back of said lid ( 3 b ).
  • the cap ( 3 ) may comprise a second peripheral cut ( 7 ) which defines the aperture area ( 3 ) in relation to the neck ( 2 ) of the bottle and which separates the body ( 3 a ) from the anchor seal ( 3 c ).
  • a plurality of second connection points ( 11 ) disposed on the inner wall of the cap ( 3 ) and on the second peripheral cut ( 7 ) can be observed in the area of this second cut ( 7 ).
  • These second connection points ( 11 ) are in charge of keeping the cap ( 3 ) body ( 3 a ) joined to the anchor seal ( 3 c ).
  • the first ( 6 ) and second cuts ( 7 ) are practically imperceptible to the human eye, giving rise to a clean outer appearance of the cap and where, additionally, there is no physical separation of the cut material prior to being torn by the user.
  • the device object of the invention may comprise a ridge ( 8 ) for facilitating the lid ( 3 b ) aperture operation.
  • the user places one of his/her fingers underneath said ridge ( 8 ) and the first connection points ( 10 ) are broken, causing separation of the lid ( 3 b ) from the body ( 3 a ).
  • the caps currently available on the market open by tearing, pulling, peeling or breaking of a part which may be a puller, tab, flange or similar with very small dimensions, which hampers cap aperture.
  • this area ( 5 ) having a greater thickness than the thickness of the cap ( 3 ) is envisaged, thereby increasing its resistance to traction, torsion and flexion stresses in said area.
  • the device object of the invention may comprise, at either side of the ridge ( 8 ), tearable vertical grooves ( 9 ) which have been weakened, in such a manner that when the slightest pressure is applied to the ridge ( 8 ), in addition to tearing the first connection points ( 10 ), these two vertical grooves will also be torn. Therefore, the inviolability of the cap ( 3 ) is guaranteed and possible adulterations of the product contained inside the bottle or container are prevented, as the user can verify at first glance whether the cap ( 3 ) has been manipulated prior to purchase.
  • the teat ( 1 ) comprises a circumferential housing ( 1 b ) which allows introduction of the neck ( 2 ) of the bottle at high pressure and a circumferential outer projection ( 1 c ) which interlocks with the first inner projection ( 3 a ′) of the cap ( 3 ) body ( 3 a ).
  • the hinge area ( 5 ) comprises two tensioning elements ( 12 ) suitable for keeping the lid ( 3 b ) in the aperture position in relation to the body ( 3 a ).
  • the lid ( 3 b ) will be retained in the aperture position by the tension provided by these tensioners ( 12 ), which are disposed on both ends of the hinge ( 5 ).
