Definitions

• the present invention relates to a decorative, tamperproof closure.
• Tamperproof closures are generally used on containers, such as bottles having a neck and a mouth, to prevent the contents being contaminated without the final consumer's knowledge. Normally, such closures also have devices which can provide evidence of the initial opening operation (also known as "tamper evident” closures) and/or devices for preventing refilling.
• the object of the present invention is to provide a tamperproof closure which is decorated internally; advantageously, the decoration should not be subject to rapid wear. According to the present invention, this object is achieved by means of a closure according to Claim 1.
• Figure 1 shows a cross-section of a first embodiment of the present invention
• Figure 2 shows a cross-section of a detail of Figure 1
• Figures 3-5 show cross-sections of three further embodiments of the present invention
• Figure 6 is an exploded, perspective view of the embodiment of Figure 1.
• the closure 1 which extends along a main longitudinal axis X-X, can be fitted on containers having a neck and a mouth, for example, on bottles, and comprises, substantially, a removable cap 2 and a main body 3 which can be fixed firmly to the neck of the container.
• the cap 2 can ensure the liquid-tightness of the closure 1 and comprises an internal thread 4 and an upper metal element 5; the internal thread 4 may optionally be formed on an inner cap 6 disposed inside and fixed firmly to the upper metal element 5, which may also be cap-shaped.
• the upper metal element 5 and the inner cap 6 may be held together by conventional, known methods, for example, by mechanical methods or by gluing.
• an intermediate cap is interposed between the upper metal element 5 and the inner cap 6 but the intermediate cap is optional; the threaded portion 4 may in fact be formed directly on the upper metal element 5, for example, by a copying process.
• the upper metal element 5 When the upper metal element 5 is separate from the threaded portion 4, the upper metal element 5 comprises an end portion 7 which extends longitudinally downwards beyond all of the other elements that make up the cap 2.
• the length of the end portion 7 as far as its end edge 8 is at least 3 mm.
• Main body 3 comprises a pourer 10 and a sleeve 11.
• there may also be means 12 for preventing re-filling such as, for example, a valve system or the like.
• the anti-ref ⁇ lling means 12 are conventional and will not be discussed further.
• pourer 10 is also conventional and has a pouring lip 13 and an externally threaded portion 14 on which the threaded portion 4 of the cap 2 is engaged.
• pourer 10 is formed integrally - by means of a flange 15 - with a lower portion 16 which has means 17 for engagement on the neck of the container; in the other embodiments, pourer 10 terminates at the bottom in the flange 15 which is firmly restrained on the neck of the container by engagement means 17 formed on sleeve 11.
• a washer 18 may be inserted between the flange 15 and the mouth of the container with the function both of supporting the anti-ref ⁇ lling means 12 and of forming the liquid-tight seal against the mouth of the container.
• pourer 10 is fitted on the washer 18 with interference.
• portions which interfere with one another are in fact shown graphically as undeformed, co-penetrating portions.
• Figure 2 shows the particular profile of the internal and external threads which is selected to permit correct operation of the closure 1.
• the angle ⁇ is advantageously between 30° and 75°, more advantageously between 45° and 75°, and even more advantageously greater than 50° and/or less than 70°, for example, about 45°.
• This fracture line 19 defines the upper edge of sleeve 11.
• An upper flange 20 of sleeve 11 is positioned immediately below fracture line 19 and has the function of restraining pourer 10 axially and/or rotationally on the neck of the container.
• the sleeve 11 comprises the means 17 for engagement on the container, preferably in the form of a continuous, upwardly- facing tab 21; in the embodiment of Figure 4, however, sleeve 11 comprises means for preventing removal, for example, a projection 23 which can remain fitted in the lower edge 22 of lower portion 16 if sleeve 11 is subjected to an upward pull.
• Sleeve 11 may comprise anti-rotation means 24 which prevent it from rotating relative to the neck of the bottle.
• the prevention of rotation may then be transferred to pourer 10 by suitable means 25, for example, opposed teeth arranged on flanges 15 and 20, respectively.
• Sleeve 11 comprises an upper portion 26 delimited by flange 20 and a lower portion 27 delimited by lower end 38 of sleeve 11.
• Upper portion 26 advantageously has a slightly smaller outer diameter than lower portion 27, the transition between the two being formed by a surface 28 which is advantageously tapered.
• a lower metal element 29 which is advantageously sleeve-shaped, is arranged around at least a portion of sleeve 11.
• Upper edge 30 of lower metal element 29 is arranged close to end edge 8 of upper metal element 5.
• the two metal elements 5, 29 are advantageously arranged adjacent one another and consecutively. Elements 5, 29 may be joined together by bridges 31 or may be completely separate.
• Guide means 32 are advantageously arranged close to end edge 8 so that, during the fitting of cap 2 on main body 3, end edge 8 remains far enough from the outer surface of upper portion 26 of sleeve 11 not to scrape the outer surface of upper portion 26 with its sharp edges.
• the guide means 32 may be formed either on upper metal element 5, for example as shown in the drawings in the form of an annular channel projecting towards upper portion 26, or - conversely - on upper portion 26 itself, for example, in the form of an annular projection extending towards metal element 5.
• the depth of the channel is substantially equal to the clearance between upper metal element 5 and upper portion 26 (or sleeve 11).
• the guide means 32 may be portions of a channel or of a projection, or internal/external boss-like spot protuberances; clearly, the number and angular extent of the guide means 32 may be selected and varied at will, provided that there is no unreliability when centering metal element 5 on sleeve 11.
• the guide means 32 advantageously have a projection of at least 0.1 mm, preferably about 0.2 mm, relative to the reference diameter (inner or outer) of elements 5, 26 on which they are formed.
• a corresponding channel (not shown) may be formed on upper portion 26 so as to form a slight snap-fit upon re-closure.
• upper portion 26 may comprise anti-tamper means 33, for example, spacer means, advantageously in the form of one or more lips 34 arranged around the circumference and facing upwards.
• the anti-forcing means 33 are visible after re-closure, irreversibly changing the appearance of the closure 1 after the initial opening operation.
• Lip 34 of Figure 3 is resiliently restrained by upper element 5, in the interior thereof and, as a result of the initial opening operation, moves outwardly so that, during re-closure, end edge 8 of upper element 5 comes into abutment with upper surface 35 of lip 34, opening it out further. Lip 34 also acts as a spacer, preventing complete closure of cap 2 onto main body 3.
• Lip 34 may comprise an outer groove in which the edges 8, 30 of metal elements 5, 29 fit; edges 8, 30 are advantageously inwardly curved to achieve the above-described spacing effect and/or to permit a resilient movement of end edge 8 over lip 34.
• the anti-tamper means 33 are advantageously arranged substantially in the region of surface 28 between the two portions 26, 27 of sleeve 11, in the vicinity of demarcation plane 36, located between upper metal element 5 and lower metal element 29.
• the demarcation plane 36 is arranged at a level such that substantially the entire upper portion 26 is visible when cap 2 is not fitted on main body 3.
• Upper portion 26 advantageously has a length greater than 3 mm and extends substantially cylindrically through 360°.
• Lower metal element 29 may be arranged around lower portion 27 with a clearance, for example, of less than 0.3 mm, or with slight interference.
• lower metal element 29 may either be rotatable relative to lower portion 27, optionally only when a predetermined torque is exceeded, or may be restrained from rotating relative thereto, for example, by gluing.
• Lower metal element 29 advantageously has the same outside diameter and/or the same thickness as the upper metal element 5; they may also be produced by the processing of a single metal sheet, for example, an aluminium (or aluminium alloy) sheet. The processing may comprise a continuous cut through 360°, separating the two element 5, 29, or a process which forms the bridges 31.
• the axial restraining means 37 may, for example, be implemented by beading of the lower end 37 of lower metal element 29 onto the end 38 of sleeve 11, or by forming one or more grooves 39 in the lateral surface of lower metal element
• groove 39 can fit in a corresponding channel 40 formed in lower portion 27; the two grooves 39, 40 will have a depth such as to effectively prevent any attempt to axially remove lower metal element 29, while at the same time optionally allowing relative rotation, as described above.
• the invention achieves the objects set, providing a compact, tamperproof closure which has an internal portion that can be decorated in a durable manner.
• annular elements may also be formed by a plurality of annular portions which are optionally separate from one another.
• a person skilled in the art will appreciate that the characteristics of the embodiments described may be interchanged if necessary.
