Definitions

  • the present invention relates to a closure, namely for containers.
  • the invention relates to a closure for containers for carbonated liquids such as soft drinks, but is well adaptable to seal other containers such as glass or PET containers with contents at above or below atmospheric pressure or having gaseous components or requiring a hermetic seal.
  • Packages for liquids, such as beverages, are often closed by screw caps which can be removed before usage and allow the package to be sealed again after usage, such as pouring the liquid out of the liquid container.
  • the crew cap seals the container if attached and further prevents a contamination of the liquid.
  • the outlet is usually circular with respective larger diameter and permits a high flow rate. The outlet is primarily designed in order to pour the liquid and not to drink directly from the beverages.
  • closures may include a base portion having a spout, which the user can place directly inside the month and therefore needs to meet high standards with respect to cleanliness.
  • a valve may ensure a lower flow rate for comfortable drinking. Often, the valve may further seal the liquid container.
  • the spout is often protected by a top portion comprising a cover.
  • Such re-closable two-piece closures may therefore provide an additional tamper seal to indicate if the cover, respectively the top portion, has been removed from the spout, respectively the base portion.
  • breakable elements and a tamper band as a tamper seal are known from conventional screw caps. After tearing the breakable elements connecting the screw cap to the tamper band, the tamper band falls away leaving a visual gab between the screw cap and the tamper band, such that it can easily be detected that the container has been opened.
  • breakable elements used as a tamper seal between the base portion and the top portion of a two-piece-closure do not provide an easy visual confirmation of a broken seal.
  • a closure for a liquid container comprises a base portion and a top portion.
  • the base portion serves to be interconnected to a neck of the container and comprises a top deck and an outer skirt extending from an outer end of the top deck in a lower direction away from the top deck.
  • the outer skirt comprises a fastening means to interconnect the closure to the container neck.
  • the top deck further has a spout extending in an upper direction away from the top deck.
  • the top portion of the closure comprises an annular base interconnectable to the base portion and a cover.
  • the cover has an outer wall, which may be interconnected to the annular base by a hinge.
  • At least one tamper element extends from the annular base in the upper direction above the annular base along the outer wall of the cover but spaced a distance apart from said outer wall.
  • the tamper element is initially (before initial opening) interconnected to the outer wall by at least one predetermined breaking linkage.
  • the tamper element may be accommodated in a pocket formed in the outer wall of the cover to avoid unwanted protrusion above the outer surface of the closure.
  • a rib may extend from the outer wall of the cover to interconnect the cover with the tamper element.
  • the at least one predetermined breaking linkage is arranged between the rib and the tamper element, but other positions may also be suitable.
  • the rib has an in general T-shaped cross-section in the upper direction.
  • the tamper element may be formed comprising an opening, which is initially closed at least partially by a part of the rib and/or the at least one predetermined breaking linkage.
  • the rib may comprise a widening at its outer end facing away from the outer wall (as it is the case for a T-shaped cross section).
  • the tamper element is interconnected to the annular base by a hinge arrangement as described hereinafter in more detail.
  • the hinge arrangement is preferably arranged between the annular base and the predetermined breaking linkage, such that the tamper element can be bent away from the outer wall after tearing the predetermined breaking linkage.
  • the hinge arrangement may provide at least one stable position in which the tamper element remains bent away from the cover such that a user may open and close the cover or drink from the spout without hindrance.
  • the hinge arrangement comprises a first and a second stable position.
  • the tamper element may extend along the outer wall of the cover meanwhile in the second stable position the tamper element remains bent and folded away from the cover, as explained above, reliably indicating initial opening.
  • Good results can be achieved when the hinge arrangement of the tamper element comprises at least two film-hinges V- or arch-shaped, extending away from each other in an outward direction.
  • the hinge arrangement can e.g. comprise four film-hinges arranged in pairs to each other.
  • the tamper element may further feature additional folding means such as one or more fold points arranged in the tamper element allowing the tamper element to bend away more easily.
  • the hinge arrangement folds away the tamper element from the cover and snaps to the at least one stable position. If only one stable position of the tamper element in the folded state is present, the tamper element cannot stay in the upright and unfolded position, once the predetermined breaking linkage is damaged, and will remain in the stable folded position. Hence, there will be a clear visual evidence that the tamper element has been tampered with.
  • the at least one predetermined breaking linkage may be designed in form of a film layer, which breaks, respectively tears, during initial opening of the closure.
  • the film layer may have the shape of a strip or a square or have a circular design. Other forms are also possible.
  • the film layer is arranged to initially close (at least partially) an opening in the tamper element, as described above. Depending on the thickness of the film layer and/or the size of the opening, the film layer may thus be used to prevent that the tamper element cannot be hooked, respectively latched, back in the initial unfolded position once the tamper element has been bent away.
  • the rib may be used to form an undercut with the opening of the tamper element to secure the tamper element to the cover after initially tearing the predetermined breaking linkage and reclosing of the closure, respectively the tamper element.
  • the tamper element may be used as a closure element to secure the cover to the annular base after the predetermined breaking linkage is torn apart.
  • the tamper element may e.g. be positioned close by the hinge.
  • the tamper element gives a user an easy to determine visual impression if the liquid container has been opened before or has been tampered with in any way.
  • the closure may additionally provide fragile bridges interconnecting the cover and the annular base along the circumference of the closure.
  • the top portion of the closure can be used with other base portions or as a closure in itself being directly attached to a container and the cover covering an opening in the container.
  • the closure is made of plastic.
  • the closure may be manufactured by injection molding.
  • One or multiple plastic components may be used for different parts, respectively regions of the closure.
  • FIG. 1 is a first variation of the closure 1 according to the invention in a perspective and partly sectionized view;
  • FIG. 2 is a detail A of the tamper element 13 according to FIG. 1 ;
  • FIG. 3 is the first variation of the closure 1 according to FIG. 1 in a second perspective view
  • FIG. 4 is the first variation of the closure 1 according to FIG. 1 in a perspective view with the tamper element 13 bent backwards;
  • FIG. 5 is a detail B of the tamper element 13 according to FIG. 4 .
  • FIG. 6 is a top portion 8 of a second variation of the closure 1 according to the invention in a partly sectionized view from the side,
  • FIG. 7 is a detail of the tamper element 13 according to FIG. 6 .
  • FIG. 8 is a third variation of the tamper element 13 .
  • FIG. 9 is a fourth variation of the tamper element 13 .
  • FIG. 10 is a fifth variation of the tamper element 13 .
  • FIG. 11 is a sixth variation of the tamper element 13 .
  • FIG. 12 is a seventh variation of the tamper element 13 .
  • FIG. 1 and FIG. 3 both show a first variation of the closure 1 for a liquid container (not shown) in a perspective view.
  • the closure 1 is further partly sectionized.
  • FIG. 2 illustrates a detail A of the tamper element 13 according to FIG. 1 .
  • FIG. 4 discloses the closure 1 with the tamper element 13 bent backwards.
  • FIG. 5 further shows the detail B of the tamper element 13 according to FIG. 4 .
  • FIG. 6 illustrates a top portion 8 of a second variation for a closure 1 according to the invention from a side view.
  • FIG. 7 shows a detail of the tamper element 13 of FIG. 6 .
  • FIG. 8 to FIG. 12 show further variations of a tamper element 13 according to the invention.
  • the shown variations of the tamper elements 13 may be used in combination with a base portion 2 and any top portion 8 of a closure 1 , as described above.
  • only one stable position of the tamper element in the folded state may be present, or multiple, such as two, stable positions can be used instead.
  • the tamper element 13 of the top portion 8 of FIG. 6 or FIG. 7 features a rib 17 in form of a bridge between the outer wall 11 and the tamper element 13 arranged behind the tamper element 13 and thus not visible in FIG. 6 .
  • the tamper element 13 is interconnected to the outer wall 11 by a predetermined breaking linkage 14 .
  • the rib 17 may e.g. comprises a predetermined breaking linkage 14 .
  • the predetermined breaking linkage 14 may be arranged between the rib 17 and the tamper element 13 or between the rib 17 and the outer wall 11 .
  • the tamper element 13 of FIG. 8 differs from the tamper element 13 of FIG. 7 only by the presence of additional folding means 21 .
  • the folding means 21 e.g. in form of multiple fold points or lines, can further facilitate the procedure of folding back the tamper element 13 and minimize the space needed for the folded tamper element 13 .
  • further visual tamper evidence may be provided by stress whitening of the material.
  • the rib 17 of the tamper element 13 according to FIG. 9 and FIG. 10 is interconnected to the tamper element 13 via the predetermined breaking linkage 14 in form of a tearable film layer.
  • the film layer 14 may have the shape of square ( FIG. 9 ) or a circular design ( FIG. 10 ) arranged to initially close (at least partially) an opening 18 in the tamper element 13 . Other shapes are also possible.
  • the film layer 14 is deformed and broken. This further aids the visual tamper evidence from the front and side.
  • the film layer may be used to prevent that the tamper element may to be latched back and held in place in the unfolded position once the film layer has been destroyed.
  • FIG. 11 shows a tamper element 13 , with a predetermined breaking linkage 14 in form of two tearable film layer sections on either side of the rib 17 extending through an opening 18 of the tamper element 13 .
  • These film layer sections 14 will deform and tear when the tamper element 13 is pulled down.
  • One advantage of the variation is that the broken breaking linkage 14 is visible from the front and side. Furthermore, the tearable film layer again prevents the tamper element to latch back in an upright position.
  • the tamper element 13 of FIG. 12 differs from the design of FIG. 11 , in that multiple film layer section 14 are present on either side of the rib 17 . In the shown example, four sections on each side of the rib 17 can be seen. However, other numbers of multiple breaking linkages 14 are possible.
  • the multiple linkages 14 having a smaller dimension than e.g. the linkage of the tamper element of FIG. 11 may even further prevent the tamper element 13 from being latched back in place.
