Definitions

• the invention relates to a closure for a container and a system comprising a container with such a closure.
• Such closures may be used in containing and providing liquid, pasty or powdery products (e.g., an infant formula powder), such as in the chemical, pharmaceutical and/or food industry.
• a tamper evidence element is provided to indicate and save the original state, i.e. to indicate in particular an unauthorized access.
• An undamaged tamper evidence element indicates a sealed (i.e. original) state of the container and a damaged or removed tamper evidence element indicates an unsealed state of the container.
• the tamper evidence element corresponds to a film that is to be removed for the first use so that a damaged or removed state of the film thus indicates the unsealed state of the container.
• the tamper evidence element typically detaches as a small piece that needs to be discarded to avoid environmental pollution.
• a disadvantage is however that, once being detached, the tamper evidence element can be easily lost, which makes it difficult to discard or recycle the tamper evidence element.
• the closure comprising the tamper evidence element such as in the form of a (shrink) film, is not easily and/or not intuitively opened when the closure needs to be initially opened. Even further disadvantages are the inferior indication of the unsealed state of the container by the tamper evidence element and a two-handed-operation, in particular for opening the closure and removing the tamper evidence element.
• a closure for a container comprises: a first part; and a second part relatively movable to the first part to move between a closed condition, in which an opening of the closure is covered, and an open condition, in which the opening is uncovered.
• the closure further comprises a tamper evidence element that is, on the one hand, connected to the second part by a frangible connection and that is, on the other hand, arranged to be withheld relative to the first part such that, as the second part moves with an opening motion relative to the first part from the closed condition to the open condition, the opening motion ruptures the frangible connection.
• the tamper evidence element is adapted to be actuated in order to rupture the frangible connection independent of moving the second part relative to the first part by the opening motion.
• the closure further comprises a holding device arranged on (and preferably integrally formed with) the first part and adapted to secure the tamper evidence element to the first part after the frangible connection has been ruptured.
• the holding device thus advantageously effects that the tamper evidence element does not get lost once the frangible connection has been ruptured and, due to this rupturing, disconnects the tamper evidence element from the second part. Therefore, the tamper evidence stays connected to the closure, after the frangible connection has been ruptured; i.e. a non-detachable tamper evidence element is provided. This reduces the risk that the tamper evidence element pollutes the environment, since the closure does not generate this element as a small piece (e.g. of plastic) prompt for littering (i.e. an improved sustainability is achieved).
• the holding device serves as a loss prevention device for the tamper evidence element. Consequently, the tamper evidence element can be better recycled, e.g. together with other parts of the closure and/or with the main packaging material (such as the container) in a same recycling stream. This significantly increases the chances of recycling the tamper evidence element.
• the tamper evidence element can be actuated to rupture the frangible connection (i.e. the tamper evidence is at least in part designed as an actuating element), a user can more intuitively and more easily open the closure for the first use. And since a user perceives the tamper evidence element as an element to be actuated (i.e. as an actuating element), the (visual, haptic, etc.) indication of the sealed state and unsealed state is improved.
• closures Further advantages achieved by the closure are a (overall) reduced size and weight (up to 15% weight reduction; particularly compared to closures (hinged lids, etc.) that have a tamper evidence element not being a shrink sleeve or a tear band), the elimination of a shrink sleeve as a tamper evidence element, an improved look and feel.
• the holding device may be adapted to withhold the tamper evidence element relative to the first part as the second part moves relative to the first part by the opening motion to allow rupturing of the frangible connection.
• the holding device thus serves both for securing the tamper evidence element once the frangible connection has been ruptured and for withholding the tamper evidence element during the opening motion (which thus ruptures the frangible connection).
• a closure is provided that is simply designed and easy to produce.
• the holding device may be adapted to secure the tamper evidence element such that, after the frangible connection has been ruptured, the tamper evidence element is movable relative to the holding device with a defined play.
• the movability of the tamper evidence element with the defined play effects a clear (visual and/or haptic, etc.) indication for a user that the frangible connection is ruptured and that the closure is, thus, in an unsealed state.
• this defined play may not be present due to the non-ruptured frangible connection.
• a user can, with the defined play, easily distinguish between a sealed state and unsealed state.
• the holding device may comprise a section for securing the tamper evidence element to the first part, wherein the tamper evidence is, by actuating the tamper evidence element, movable towards this section in order to rupture the frangible connection.
• the tamper evidence element is secured to the first part by the section (and thus is, for example, less visible from outside of the closure, i.e. does not represent a key visible element anymore)
• a user can easily determine that the tamper evidence element has been actuated (e.g. actuated to rupture the frangible connection); the closure is then transitioned to a state, in which attention is drawn to the opening of the closure by the opening motion.
• the holding device provides a device for easily distinguishing between a frangible connection ruptured by the opening motion and a frangible connection ruptured by the actuation of the tamper evidence element.
• the section is adapted to secure the tamper evidence element such that the tamper evidence is not movable relative to the holding section or is movable relative to the holding section with a further defined play, which is preferably less than the before-mentioned defined play.
• a user can easily determine (e.g. visually and/or haptically) whether the tamper evidence element has been actuated, and/or determine (e.g. visually and/or haptically) whether the frangible connection has been ruptured by the opening motion or the actuation of the tamper evidence element.
• the holding device in particular the section, may be adapted to secure the tamper evidence element with a snap fit.
• a snap fit provides a particularly safely securing of the tamper evidence element to the first part. This in turn effects that the tamper evidence element is not easily lost after the frangible connection has been ruptured. Further, the securing of the tamper evidence element by the snap fit provides a clear (visual and/or haptic) indication for the tamper evidence element being in the unsealed state effected by the actuation of the tamper evidence element.
• the snap fit does not provide the defined play and/or the snap fit provides no (defined) play or at least the further defined play. As such, a user can easily determine whether the tamper evidence element has been actuated and/or determine whether the frangible connection has been ruptured by the opening motion or by the actuation of the tamper evidence element.
• the tamper evidence element can engage with the section, such as with a snap action, by the user’s actuation of the tamper evidence element, but preferably not by the opening motion.
• the section may be arranged such that only the actuation of the tamper evidence element can effect that the tamper evidence element moves into a position to be secured by the section, in particular by the snap fit.
• the tamper evidence element may be adapted to be pushed in order to be actuated.
• the tamper evidence element can be very easily actuated in order to rupture the frangible connection. This effects that the closure is very easily and intuitively operable, in particular for the first use when the frangible connection needs to be ruptured.
• the tamper evidence element may comprise a defined actuation (e.g. pushing) surface that can be actuated (e.g. pushed) by a user. This actuation surface may be visible when viewed onto the second part and/or along a direction perpendicular to a flat surface (e.g. as part of a lid portion) of the second part.
• the tamper evidence element provides, for being actuated, an improved accessibility and an improved visibility.
• the tamper evidence element is at least in part designed as a button, e.g. as a push button.
• a particularly good visibility of the tamper evidence element for indicating the sealed/ unsealed state and a particularly good actuation of the tamper evidence element for rupturing the frangible connection is provided.
• the tamper evidence element is not in form of a band (tear band, etc.) and/or not in form of a sleeve (shrink sleeve, etc.).
• the second part may comprise a wall portion, wherein, when viewed at least along a direction perpendicular to the wall portion, the tamper evidence element exposes the wall portion after the frangible connection has been ruptured.
• the exposed wall portion provides an improved indication of a ruptured frangible connection and, thus, of an unsealed state.
• the tamper evidence element covers the wall portion, when viewed at least along said direction. This improves the indication of a non-ruptured state of the frangible connection and, thus, of the sealed state.

• the section 25 may be adapted to secure the tamper evidence element 5 to the first part 1 such that the tamper evidence element 5 is not movable relative to the holding device 22 or at least movable relative to the holding device 22 with a further defined play that is less than the defined play, e.g. provided by the section 23.
• the section 25 comprises one or more protrusions for securing the tamper evidence element 5.
• the section 25 may further comprise a bottom wall 26 that, together with the one or more protrusions, can secure the tamper evidence element 5, optionally such that the tamper evidence element 5 is not movable relative to the holding device 22 or at least movable with the further defined play.
• the motion of the tamper evidence element 5 secured to the section 25 may be restricted by the one or more protrusions of the section 25 and the bottom wall 26.
• the one or more protrusions 53 of the tamper evidence element 5 may be at least partially arranged between the wall 26 on the one hand and the one or more protrusions of the section 25 on the other hand.
• the section 25 secures the tamper evidence element 5 by a snap fit, which may be provided by the one or more protrusions of the section 25 and/or the bottom wall 26.
• the (upper) section 23 may be arranged with respect to the (lower) section 25 such that the tamper evidence element 5 can be moved, by actuation, from the section 23 towards the section 24.
• “Lower section” preferably means that this section is further distanced from the second part 3 (in the closed position) than the “upper section”.
• the section 25 may be at least in part defined by one or more side walls of the holding device 22, such as also by the one or more side walls 24.
• the one or more side walls may comprise the one or more protrusions of the section 25 and/or may extend from the bottom wall 26.
• the holding device 22 may comprise a side wall 24a that is, at least after the frangible connection 51 has been ruptured, arranged to at least partially cover the tamper evidence element 5.
• the side wall 24a may be arranged to cover more parts of the tamper evidence element 5 than in a state, in which the tamper evidence element 5 is connected via the frangible connection 5 to the second part 3.
• the tamper evidence element 5 may comprise a wall portion 55, which is, when the tamper evidence element 5 is connected via the frangible connection 5 to the second part 3, exposed (i.e.
• the wall portion 55 may comprise an indication (a color (e.g. green), one or more signs, letters, a locked padlock sign, etc.) so that, when the wall portion 55 is exposed, this indication is visible.
• the wall portion 55 provides a clear visual indication for the frangible connection 51 being non-ruptured, i.e. for the closure 1 being in the sealed state.
• the side wall 24a may be arranged to cover this wall portion 55, such as to cover the indication of the wall portion 55 (see FIG. 11).
• the side wall 24a may extend from the bottom wall 26.
• the tamper evidence element 5 will displace or move by gravity relative to (and further into) the holding device 22 and be secured by the holding device 22, such as with the (upper) section 23, with the defined play (with reference to FIG. 5: the tamper evidence element 5 displaces downwards by gravity onto the one or more protrusions of the section 25).
• the defined play is then defined by the one or more protrusions of the section 23 on the one hand and by the one or more protrusions of the section 25 on the other hand.
• the opening motion cannot effect that the tamper evidence element 5 moves into the position, in which the (lower) section 25 secures the tamper evidence element 5.
• the holding device 22 may be also used to indicate whether the frangible connection 51 has been ruptured by the opening motion of the parts 2, 3 (thereby not engaging with the section 25 but, for example, only placed on the one or more protrusions of the section 25) or by the actuation of the tamper evidence element 5 (thereby moving towards the section 25 and, for example, engaging with the same such as with the one or more protrusions of the section 25).
• the holding device 22 is adapted to provide this function. More specifically, the holding device 22, preferably the (upper) section 23, may be adapted to withhold the tamper evidence element 5 relative to the first part 2 as the second part 3 moves relative to the first part 2. If withholding is effected by the section 23, the one or more protrusions of the section 23 may engage with the tamper evidence element 5, such as with its one or more protrusions, in order to withhold the tamper evidence element 5.
• the tamper evidence element 5 may interact with the wall portion 33 of the second part 3 in order to provide a particularly good indication of the sealed state and unsealed state. For example, after the frangible connection 51 has been ruptured, in particular by actuating the tamper evidence element 5, the tamper evidence element 5 exposes the wall portion 33 (when viewed along a direction perpendicular to the wall portion 33, which is, in FIG. 5, perpendicular to the drawing plane). In other words, as the tamper evidence element 5 moves (such as by gravity and/or by actuation) due to the ruptured frangible connection 51, the tamper evidence element 5 at the same time moves along the wall portion 33 and, thus, exposes or uncovers the wall portion 33.
• the wall portion 33 may comprise an indication (a color (e.g. red), one or more signs, letters, an unlocked padlock sign, etc.) so that, when the wall portion 33 is exposed, this indication becomes visible for indication of the unsealed state.
• the wall portion 33 provides a clear visual indication for the frangible connection 51 being ruptured, i.e. for the closure 1 being in the unsealed state.
• the closure 1 is preferably a reclosable and/or resealable closure or lid.
• one or more fastening elements 6 are provided, which, in the closed condition of the closure 1, fasten the parts 2, 3 with one another.
• the first part 2 and/or the second part 3 may comprise the one or more fastening elements.
• the one or more fastening elements may fasten the parts 2, 3 to one another by a form and/or frictional fit and/or by a snap fit.
• the one or more fastening elements 6 are preferably designed such that the opening motion of the parts 2, 3 can release the fastening connection provided by the one or more fastening elements 6, thereby unfastening the parts 2, 3 to move the closure 1 into the open condition.
• the first part 2 and the second part 3 preferably sealingly engage with (or sealingly contact) one another.
• a sealing is shown in FIG. 6B.
• the first part 2 may comprise a sealing wall 27 that comprises at least an angled (or horizontal) section 28 and preferably a straight (or vertical) section 29.
• the angled section 28 preferably extends horizontally and/or at an angle (perpendicular, oblique, etc.) with respect to the straight section 29.
• the sealing wall 27 is preferably a circumferential wall.
• the second part 3 comprises a first wall 34 and a second wall 35, wherein the second wall 35 is further distanced from an outer edge of the second part 3 than the first wall 34.
• the second wall 35 may be arranged in a space delimited by the first wall 34.
• the first wall 34 is the outer edge.
• the first wall 34 (sealingly) contacts, e.g. with a stepped portion, the sealing wall 27, such as the angled section 28 but preferably not the distal end of the sealing wall 27. Additionally or alternatively, the first wall 34 may contact, in the closed condition, the straight section 29 of the sealing wall 27. In the closed condition, the first wall 34 contacts the sealing wall 27 (such as the angled section 28 and/or the straight section 29) preferably with a flat contact. Further, in the closed condition, the second wall 35 contacts (e.g. only) the angled section 28, such as the distal end of the sealing wall 27 that is part of the angled section 28.
• the sealing wall 27 (such as the angled section 28), the first wall 34 and the second wall 35 may be arranged to delimit a cavity 36.
• a particularly good sealing is provided, in which the second wall 35 contacting the angled section 28 provides an “inner sealing”, and the first wall 34 contacting the sealing wall 27 provides an “outer sealing”. Accordingly, a particularly good sealing is provided, which prevents a fluid (such as oxygen, air, liquid, pasty mass) to pass the interface between the first part 2 and the second part 3. This in particular prevents, in the closed condition, leakage of the product by way of the closure 1 and/or degradation of the product inside of the container by a fluid (in particular oxygen) flowing from the outside via the closure 1 into the container.
• a fluid such as oxygen, air, liquid, pasty mass

• the closure 1 may be produced by any suitable production method, such as injection molding.
• the closure 1 is obtained in the open condition (such as in the state shown in FIGS. 8A-B, 9, 10A), in which the first part 2 is integral with the second part 3 (e.g. by way of the hinge 4) and the tamper evidence element 5 is integral with the second part 3 by way of the frangible connection 51.
• the second part 3 may move relative to the first part 2 in order to connect the tamper evidence element 5 to the first part 2, namely such that the tamper evident element 5 can be withheld relative to the first part 2 as the second part 3 moves relative to the first part 2 with the opening motion.
• FIG. 16D shows the state shortly before being connected to the first part 2.
• the tamper evidence element 5 attaches or engages (e.g. snaps into) the holding device 22 for being withheld.
• the tamper evidence element is connected to the first part 2 in such a way that the frangible connection 51 does not rupture.
• the closure 1 in the sealed state is obtained and ready for application, e.g. for attaching to a container.
• the closure 1 is not limited to a specific material.
• the closure 1 may be made of a transparent and/or opaque material.
• the closure 1 is partially or completely made of a bio-based and/or biodegradable material, such as bio-based and/or biodegradable polypropylene (PP).
• the closure 1 may be partially or completely made of a thermoplastic material, such as polypropylene (PP), polyethylene (PET) and/or plastic.
• PP polypropylene
• PET polyethylene
• plastic polypropylene
• a bio-based and/or biodegradable material is preferred.
• the closure 1 may comprise defined portions, such as weakened portions, which facilitate a disassembly of the closure 1 in different parts, e.g.
• the second part 3 comprises a portion 37, which facilitates an easy disassembly of the second part 3, such as by easily cutting along the portion 37 (e.g. with a scissor) in order to disassemble the second part s.
• the closure 1 is not limited to specific dimensions. That is, the tamper evidence element 5 can be used with closures (lids, etc.) and/or containers with any sizes or dimensions.
• the closure 1 may be suitable for big diameter containers, which have a diameter in the range from 73mm to 127mm.
• the closure 1 has a diameter in the range from 73mm to 127mm, in particular from 80mm to 120mm or from 90mm to 110mm.

• the second part 3 may comprise these one or more structures 38.
• the one or more structures 38 may be arranged on a backside of the second part 3, which faces away from the lid part 31. In other words, the one or more structures 38 may be, in the closed condition, arranged between the opening 21 and the lid part 31.
• the first part 2 may be attached to the container by a form and/or frictional fit and/or by an adhesive bond.
• the first part 2 may comprise one or more fastening elements (such as in the form of a snap fit) 200 for attaching and fastening the first part 2, and thus the closure 1, to the container.
• the fastening force provided by the one or more fastening elements 200 for attaching the first part 2 to the container is preferably such that the closure 1 cannot be disassembled from the container without damaging the closure 1 and/or the container.
