Definitions

  • the present invention relates to a bottle dispenser cap.
  • the dispenser cap which is the object of the present invention, is structured to allow a user to hermetically close the neck of a bottle containing a beverage and open the bottle allowing the beverage to be dosed.
  • dispenser caps which are generally designed to allow the user to carry out, in addition to the usual opening and closing of the bottle, an adjustment of the amount of beverage dispensed from the bottle itself.
  • Some types of bottle dispenser caps comprise a cylindrical base screwed onto the bottle neck, a frustoconical dispenser body which is stably connected to the base so as to form a single body with it, and a lid provided with an inverted cup-shaped body and a hinge laterally connecting the cup-shaped body to the base.
  • the dispenser body has, centrally in the upper end part, a through opening forming a beverage dispenser orifice, whereas the cup-shaped body of the lid is structured so as to rotate via the hinge between an open position and a closed position in which the perimeter edge of the cup-shaped body is coupled to the upper perimeter edge of the base so as to include the dispenser body on the inside.
  • the cup-shaped body of the lid is generally structured so that internally it has a central protrusion which engages the orifice of the dispenser body when the cup-shaped body is arranged in the closed position so that it hermetically closes the bottle to prevent, on one side, accidental spillage of the beverage, and on the other side, its contamination by external contaminants.
  • dispenser caps comprise a central valve body which is mounted so that it can axially slide on the outer wall of an upper cylindrical tubular portion of the dispenser body so that it is manually moved by the user between a closed position, in which the valve body is lowered and engages the orifice by means of an internal protruding appendage so as to close it, and an open position, in which the valve body is raised so as to disengage the orifice and open the bottle to allow the user to drink the beverage.
  • the hinges used in the aforementioned lids of the dispenser caps generally have a brace-like structure characterized by the presence of small through slits or openings between the braces, or between the braces and the cup-shaped body, which do not allow the space inside the lid to be hermetically isolated.
  • the dispenser cap is indeed exposed to contamination by external agents during its storage in the warehouse prior to its assembly on the bottle body. In fact, it is often the case that, during the process, the caps accidentally stack on each other in a so-called "nesting" configuration before being assembled with the bottle body. In the nesting condition, the components of the caps undergo small axial displacements, resulting in the formation of small openings which, together with the slits in the hinge, cause contaminants to enter the cap.
  • the cap is also exposed to contamination by external agents even after the user first opens the cap. Indeed, after the first opening, in addition to the slits structurally present in the hinge, other slits also form due to mechanical clearances, especially along the closing edges of the lid, which allow contaminants to enter.
  • the sanitization liquid enters the cap through these slits, becoming partially trapped inside it. Under these conditions, the sanitization liquid trapped inside the cap then comes into contact with the beverage and/or the user's mouth during the use of the bottle.
  • dispenser cap which, on the one hand, overcomes the above-described drawbacks from contamination without the use of the protective film, and on the other hand, has a structure such as to reduce the risk of suffocation of the user due to accidental swallowing of component parts of the dispenser cap, and which reduces the risk of environmental impact of the cap caused, for example, by its decoupling from the bottle and its dumping in the environment following the opening of the bottle.
  • the object of the present invention is thus to provide a solution which allows at least the above-mentioned goals to be achieved.
  • the number 1 indicates a bottle as a whole.
  • the bottle 1 is suitable for containing food-grade beverages such as, for example, water, orange juice or any other natural, smooth or carbonated beverage.
  • the bottle 1 is preferably made of a polymeric material, e.g. PET (polyethylene terephthalate) or any other similar plastic/polymeric material.
  • the bottle 1 comprises a cylindrical tubular body at the top defining a neck 2, and a containment body 3 at the bottom, which is suitable for containing the beverage and is connected to the neck 2 at the top.
  • the bottle 1 is further provided with a dispenser cap 4 which is coupled to the neck 2 in order to close its mouth.
  • the dispenser cap 4 is conveniently a tethered cap, i.e., it is designed to remain permanently bound to the neck 2 even after opening it.
  • the technical effect of the tethered dispenser cap 4 is to prevent the user from separating the same dispenser cap 4 from the neck 2 of the bottle 1 in order to reduce the risk of the dispenser cap 4 being thrown into the environment and polluting it.
  • the dispenser cap 4 has an axis A and comprises a body-base 5 that is tethered to the neck 2 so as to remain bound to it ( Figures 4 and 5 ), an upper lid 6 that is coupled to the body-base 5 in the way described, and a dispensing valve 7 ( Figures 2, 3 , 19-21 ) that is coupled to the body-base 5 and is configured to allow the user to selectively close, open and adjust the dispensing of the beverage from the bottle 1.
  • the body-base 5 extends along the axis A, coaxially therewith, and inferiorly comprises a tubular portion 8, which has a substantially cylindrical shape and extends along the axis A, coaxially therewith, a tubular portion 9, which has a substantially cylindrical shape and extends along the axis A, coaxially therewith, above the portion 8 and is peripherally connected to the latter via a flat annular portion 10 approximately transverse to the axis A.
  • the body-base 5 also comprises a portion 11, which is preferably, but not necessarily, frustoconical, extends along the axis A, coaxially therewith, above the portion 9 and is peripherally connected to the latter via an annular portion 12 approximately transverse to the axis A.
  • the body-base 5 further comprises a central sleeve 13 extending coaxial to the axis A and having: an upper cylindrical portion 13a externally connected, in an axially intermediate position, to the upper perimeter edge of the frustoconical portion 11, a lower cylindrical portion 13b, which is arranged below the portion 13a, has an outside diameter less than the outside diameter of the portion 13a, and has its upper perimeter edge connected to the lower perimeter edge of the portion 13a by a conical portion 13c, and the lower perimeter edge connected to a flat base 13d orthogonal to the axis A.
  • the base 13d features a central through-opening 14, coaxial with the axis A, which is shaped so as to have a central circular hole from which apertures 14a extend radially towards the outer perimeter of the base 13d, said apertures 14a being angularly spaced from each other around the axis A.
  • the apertures 14a are preferably rectangular.
  • the apertures 14a radially divide the base 13d into as many tongues 15 ( Figure 15 ).
  • the upper (internal) surface of the base 13d facing the inside of the sleeve 13 has an approximately conical section passing through the axis A so that the upper faces of the tongues 15 are inclined.
  • the lower surface of the base 13d opposite the upper surface thereof is preferably flat and lies in a plane substantially orthogonal to the axis A.
  • the dispensing valve 7 is telescopically engaged within the sleeve 13 so that it slides axially therein so as to be translated along the axis A between a closed position (lowered, as shown in Figures 2, 3 , 12 , 17 ) in which it hermetically closes the opening 14 of the base 13d so as to hermetically close the bottle 1, and an open position (raised, extracted, shown in Figures 14 and 18 ) in which the dispensing valve 7 opens the underlying opening 14, so that the dispensing valve 7 is in hydraulic communication with the containment body 3 to allow the dispensing of the beverage.
  • a slight adjustment of the axial position of the dispensing valve 7 along the axis A, in the closed position, allows the dispensing of the beverage to be varied.
  • the technical effect of the dispensing valve 7 telescopically engaged within the sleeve 13 is to reduce its risk of contamination, especially when it is in the closed position as it is at least partially protected by the sleeve 13.
  • the dispensing valve 7 comprises a tubular portion 7a having a cylindrical shape coaxial with the axis A.
  • the portion 7a is telescopically engaged within the portion 13a of the sleeve 13 in contact with its inner surface, so as to move axially along the axis A to and from the underlying base 13d.
  • the dispensing valve 7 also comprises, at the top, an annular edge 7b extending cantilevered from the upper perimeter edge of the portion 7a in a radial direction, opposite the axis A, so as to project at least partially above the upper perimeter edge of the underlying portion 13a ( Figure 12 ).
  • the annular edge 7b is substantially circular and is structured so that its lower face abuts against the upper perimeter edge of the sleeve 13 when the dispensing valve 7 is in the closed position.
  • the annular edge 7b conveniently serves as the upper limit stop of the dispensing valve 7 and is structured to block the axial travel of the latter along the axis A when it reaches the closed position.
  • the dispensing valve 7 also comprises, at the bottom, a flat circular base 7c orthogonal to the axis A.
  • the base 7c is sized such that it is engaged by interference in the portion 13b against the inner surface of the portion 13b itself when the dispensing valve 7 is in the closed position, so that the opening 14 is hermetically closed.
  • the base 7c is connected to the portion 7a by a series of spokes 7d.
  • the spokes 7d are arranged angularly equidistant from each other around the axis A, extend radially cantilevered from the upper face of the base 7c and are connected at the top to the inner face of the portion 7a.
  • the spokes 7d are preferably shaped as a triangle and delimit, with the lower perimeter edge of the portion 7a and the outer perimeter edge of the base 7c, through-openings 17 designed to be traversed, in use, by the beverage when the dispensing valve 7 is in the open position.
  • the dispensing valve 7 also comprises, in its lower end part, a circular annular portion 7e which is arranged coaxial with the axis A and is centrally connected to the lower face of the base 7c by means of a central stem 7f which extends coaxial with the axis A and is engaged in the opening 14 of the base 13d.
  • the stem 7f is shaped so that it has a section, orthogonal to the axis A, substantially in the shape of a cross (section shown in Figure 15 ) and extends from the lower face of the base 7c (opposite the tubular portion 7a) over a length (along the axis A) substantially corresponding to the length of the axial travel/displacement that the dispensing valve 7 makes between the closed position and the open position, and vice versa ( Figures 17 and 18 ).
  • the stem 7f comprises longitudinal spokes 7g extending parallel to the axis A.
  • the spokes 7g form the four segments of the cross-shaped section.
  • the spokes 7g extend radially from the axis A in planes orthogonal to each other.
  • the spokes 7g are structured and sized so as to slide substantially in contact with the perimeter edge of the circular hole of the opening 14 when the dispensing valve 7 is translated in the sleeve 13 ( Figure 15 ).
  • the number of spokes 7g is different from the number of apertures 14a. In the example shown, there are four spokes 7g conveniently arranged orthogonal to each other, whereas there are three apertures 14a.
  • the shape and angular distribution of the four spokes 7g of the dispensing valve 7 around the axis A combined with the angular arrangement of the three rectangular apertures 14a of the base 13d (at 120° from each other) has the technical effect of ensuring that the centering of the dispensing valve 7 in the body-base 5 is maintained along the axial travel of the dispensing valve 7 in any angular position of the dispensing valve 7 around the axis A, that is, in any condition of angular offset between the spokes 7g and the rectangular apertures 14a.
  • the lower end part of the stem 7f is connected to the annular portion 7e and delimits therein four through-openings 7h.
  • the annular portion 7e is circular and has an outside diameter larger than the diameter of the central hole of the opening 14 so that its upper face abuts against the lower face of the tongues 15 obtained in the base 13d, when the dispensing valve 7 is in the open position.
  • the lid 6 comprises an annular seal 16 which is firmly fitted on the body-base 5 and extends coaxial with the axis A; a cap 18, and a hinge 19 connecting the cap 18 to the annular seal 16 and is structured to rotate the cap 18 around an axis B approximately transverse to the axis A, between a closed position (shown in Figures 1 , 4 , 8, 9 , 10, 11 and 12 ) and an open position (shown in Figures 3 and 5 ).
  • the cap 18 in the closed position, the cap 18 is coupled to the body-base 5 in order to delimit with the latter an internal closed chamber which internally contains the dispensing valve 7 and the sleeve 13.
  • the cap 18 is decoupled from the body-base 5 and is arranged substantially upside down relative to the closed position so that the user has access to the dispensing valve 7.
  • a technical effect of the dispensing valve 7 telescopically engaged within the sleeve 13 in its closed position is to keep the bottle closed even when the cap 18 is in the open position.
  • the cap 18 comprises a cup-shaped body provided with an outer side wall 18a of annular shape surrounding the axis A, and a flat upper wall 18b transverse to the axis A closing the upper opening of the side wall 18a.
  • the lid 6 is provided with a circular slot 20 (preferably sector-shaped in the example shown), extending in a circumferential direction around the reference axis A and separating the cap 18 from the annular seal 16.
  • the lid 6 is provided with a plurality of breakable bridges 21, which connect the annular seal 16 to the side wall 18a of the cap 18, or rather to the lower edge of the side wall 18a of the cap 18.
  • the breakable bridges 21 are initially intact and are structured to break when the cap 18 is first opened.
  • the integrity of the breakable bridges 21 indicates the integrity of the lid 6 prior to its first opening.
  • the breakable bridges 21 are distributed at a certain distance from each other along the slot 20.
  • the cap 18 also comprises an inner wall 18c of substantially cylindrical shape extending coaxially to the axis A.
  • the inner wall 18c extends cantilevered from the inner face of the upper wall 18b (oriented towards the body-base 5) and is structured/sized so as to engage on the portion 11 of the body-base 5, when the cap 18 is in the closed position.
  • the lower edge of the inner wall 18c is shaped so that its inner face has a section (in a plane lying on the axis A) which is approximately complementary to the section (in the same plane) of the cylindrical surface of the portion 11 on which it is engaged.
  • the inner wall 18c is engaged/fitted in the portion 11 and delimits, together with the latter, the sleeve 13, the annular edge 7b and the inner face of the upper wall 18b, an internal (substantially) hermetically closed chamber 22.
  • the hermetic closure of the chamber 22 is ensured by the fact that the portion of the base 7c is engaged by interference in the cylindrical portion 13b, and at the same time the lower edge of the inner wall 18c of the cap 18 is engaged in the portion 11.
  • the upper wall 18b delimits, with the inner faces of the dispensing valve 7, a portion of the volume of the internal (substantially) hermetically closed chamber 22.
  • a technical effect achieved by the inner wall 18c of the cap 18 engaged in the portion 11 of the body-base 5, when the cap 18 is in the closed position, is to prevent contact of the drinking surface, i.e., the surface intended to come into contact with the user's mouth, with external contaminants, both during the storage of the bottle 1 and during its use.
  • the engagement of the inner wall 18c on the portion 11 allows hermetic closure of the chamber 22, which conveniently prevents the sanitization liquid used during sanitization from entering therein.
  • Recesses are made along the lower edge 18d of the side wall 18a, the former delimiting discharge openings or windows 24.
  • the technical effect of the discharge windows 24 is to facilitate the outflow of the sanitizing fluid from the portion of the lid 6 which undergoes sanitization.
  • the annular portion 12 is shaped to have a section (in a sectional plane passing through the axis A) which is conveniently inclined outwards.
  • the inclined surface of the annular portion 12 conveys any residues of the sanitizing fluid towards the discharge windows 24, thereby facilitating the evacuation of the fluid from the dispenser cap 4 towards the external environment.
  • the cap 18 further comprises an inner centering wall 25 extending cantilevered from the inner face of the upper wall 18b in order to be coaxial with the axis A.
  • the centering wall 25 is engaged in the inner face of the upper end of the tubular portion 7a opposite the annular edge 7b, when the lid 6 is in the closed position.
  • the ribs 26 may be straight and be angularly equidistant from each other around the axis A.
  • the ribs 26 may be conveniently arranged at 120° from each other.
  • the upper edge of the portion 13a of the body-base 5 and the three spokes 26 on the inner face of the upper wall 18b of the cap 18 constrain the dispensing valve 7 axially so that it remains in the closed position with the annular edge 7b abutting against the portion 13a, when the lid 6 is in the closed position.
  • a technical effect achieved is to prevent an axial movement between the body-base 5 and the dispensing valve 7 when the latter is in the closed position.
  • the technical problem of contamination to which the sanitized surfaces of the dispenser cap 4 are exposed during the handling and transport of the dispenser cap 4 on the lines and/or when the condition of accidental stacking (nesting) occurs is therefore solved.
  • the centering wall 25 is missing a portion.
  • the removed portion is adjacent to the hinge 19.
  • the portion of the centering wall 25 facing the hinge 19 is removed.
  • the portion is removed from the centering wall 25 along a stretch or arc that is adjacent to the hinge 19 and has an angular extension of approximately 80° to 120°.
  • the technical effect of removing the portion from the centering wall 25 is to avoid interference between the centering wall 25 and the dispensing valve 7 during the opening/closing of the cap 18.
  • the removal of the centering portion 25 makes it easier for the user to open the cap 18.
  • the end portions 25a of the centering wall 25 are asymmetrical with respect to the centerline (median) plane of the dispenser cap 4.
  • the technical effect obtained is to further facilitate the opening even when the thrust point applied by the user on the cap 18 is not in the median plane.
  • the dispenser cap 4 is structured so that, when the dispensing valve 7 is in the open position, the movement of the cap 18 from the open position to the closed position causes the dispensing valve 7 to move to the closed position.
  • the wall 18c abuts against the annular edge 7b and exerts a thrust thereon which causes an axial displacement of the dispensing valve 7 within the sleeve 13 and subsequently, during the end phase of the rotation, the upper wall 18b abuts against the annular edge 7b and pushes the dispensing valve 7 inside the sleeve 13 into the closed position.
  • the technical effect is to simplify the operation of closing the dispensing cap 4 for the user, even when the dispensing valve is extracted. The user then conveniently closes the dispensing valve and cap with a single movement.
  • the hinge 19 comprises an opening 28 which is formed along a section of the circular slot 20 delimited at the bottom and top (along the axis A) by two opposite sides 28a and 28b approximately trapezoidal in shape.
  • the two sides 28a and 28b delimit, with two sides of the through opening 28 parallel to the axis A, two trapezoidal windows which are symmetrical with each other relative to a plane of symmetry lying on the axis A.
  • the trapezoidal windows are connected to each other via a central window, preferably rectangular, which runs in a direction approximately parallel to the lying plane of the circular slot 20.
  • the hinge 19 also comprises connecting braces 29 extending within the respective trapezoidal windows of the opening 28 side by side with each other and parallel to the axis A.
  • the braces 29 are substantially flexible, have an approximately trapezoidal shape, and each have the two opposite inclined sides connected, respectively, to the opposite inclined sides of the relevant trapezoidal window.
  • the cap 18 further comprises a tooth 30 which is structured so that it rests against the outer surface of the annular seal 16 to keep the cap 18 locked in the open position ( Figure 3 ).
  • the tooth 30 extends cantilevered outwards from the side portion 18a.
  • the section of the tooth 30 in a plane passing through the axis A, when the cap 18 is in the open position ( Figure 3 ) has one side 30a (the upper one in Figure 3 ) which is substantially flat and parallel to the lying plane of the lower edge 18d of the cap 18, and one side 30b opposite the side 30a (the lower one in Figure 3 ) which is inclined relative to the outer surface of the side portion 18a.
  • the side 30b is shaped so that when the cap 18 rotates and passes the dead centre in which the profile of the braces 29 ( Figure 2 ) goes beyond the axis of rotation B transverse to the axis A, the end portion of the side 30b rests against the outer wall of the seal 16 and under the elastic action of the tensioned braces 29 brings and holds the cap 18 into the open position ( Figures 2 and 3 ).
  • the technical effect of the tooth 30 is, on the one hand, to prevent accidental closing of the cap 18 and, on the other hand, to allow the cap 18 to move easily into the open position.
  • the tubular portion 8 of the body-base 5 comprises an inner surface provided with a thread having a shape complementary to the thread of the neck 2.
  • the inner surface of the tubular portion 8 is threaded so that it is coupled with (screwed in) the threaded outer surface of the neck 2.
  • the tubular portion 8 of the body-base 5 is provided with a circular slot 31 extending in a circumferential direction around the reference axis A and separating a lower annular seal 8a from an upper cylindrical portion 8b.
  • the annular seal 8a defines a guarantee ring or guarantee band and is fitted on a lower portion of the neck 2, below an annular flange 2a extending cantilevered from the neck 2.
  • the connecting braces 8d are approximately L-shaped.
  • the connecting braces 8d comprise a major plate-like (ribbon-like) segment or portion 8e extending from the annular seal 8a in a circumferential direction over a stretch with a predetermined angular width.
  • the connecting braces 8d comprise a minor plate-like (ribbon-like) segment or portion 8f extending from the free end of the major portion 8e in an axial direction (parallel to the axis A) and joining/connecting to the upper portion 8b, preferably to its lower edge.
  • the width of the connecting braces 8d is approximately constant.
  • the width measured along a direction parallel to the axis A of the major portions 8e is approximately equal to the width measured in the circumferential direction of the minor portions 8f.
  • the minor portions 8f have a width measured in the circumferential direction that is greater than the width of the major portions 8e.
  • the minor portions 8f have a width measured in the circumferential direction that is smaller than the width of the major portions 8e.
  • the connecting braces 8d, or rather the major portions 8e, are also of such length that the body-base 5 can translate along the reference axis A towards the upper opening of the neck 2, while the annular seal 8a is retained against the annular flange 2b, preferably by anchoring ribs (not shown) present in the annular seal 8a itself.
  • the connecting braces 8d are arranged symmetrically, i.e., in mirror images of each other.
  • the major portions 8e are obtained by creating on the annular seal 8a a pair of separation lines, i.e., slots, extending in a circumferential direction, so that the corresponding major portions 8e of the connecting braces 8d are separated from the annular seal 8a.
  • the major portions 8e of the connecting braces 8d originate from two diametrically opposite points of the annular seal 8a.
  • the minor portions 8f extend bridge-wise in the axial direction between the free end of the major portion 8e and the lower edge of the upper portion 8b.
  • the connecting braces 8d of the portion 8 of the tubular body 5 can be conveniently made in an equivalent way to the connecting braces of the cap described in the Applicant's Italian patent application no. 102022000006725 , the contents of which are understood to be incorporated herein by reference in their entirety.
  • the advantages of the dispenser cap are at least the following.
  • the design of the dispenser cap allows a closed chamber to be obtained, which prevents the drinking surface from coming into contact with external agents both during the storage of the dispenser cap and during its use.
  • the same flexibility generated both by the stiffness of the material and by the three blocks defining the tongues allows a deformation useful for the insertion of the dispensing valve, avoiding permanent deformation thereof.
  • the difference in the number of tongues compared to the number of spokes on the dispensing valve stem allows adequate centering between the body-base and the dispensing valve throughout the opening stroke and at any offset angle between the two.
  • the beverage flow is ensured both by the openings in the dispensing valve and by the apertures 14a delimiting the tongues 15 of the body-base.
  • the cap has a locking tooth, prominent in relation to the main body, which allows the locking thereof when the cap is open.
  • the profile of this tooth has an inclination such that it is tapered in the upper portion, which allows the cap to be kept open in a stable equilibrium position.
  • the cap when it overturns, thus opening, passes a dead centre situation when the profile of the braces goes beyond the axis of rotation, defined as the point of contact between the tooth and the cap seal.
  • This system limits accidental closure of the cap and makes reaching the open condition more appreciable.
  • the centering element between the cap 18 and the dispensing valve 7 deprived of one of its parts, and more precisely, of a portion diametrically opposite the opening thrust point, allows the force needed to open the cap to be reduced, as there is no contrast against the dispensing valve caused by the user pushing the cap to open it.
