Definitions

  • Dispensing closures of this type comprise generally a closure body having a deck and a circumferential skirt, wherein a dispensing orifice is formed in the deck.
  • a lid is hingedly connected to the closure body, the lid having a closed state in which it covers the dispensing orifice and at least a part of the deck, and having an open state in which it is swivelled away from the deck such that a product can be dispensed from the container through the dispensing orifice.
  • Such dispensing closures are commonly made of a plastics material by injection moulding.
  • the closures are adapted to be arranged on containers such as for example drinking bottles, squeeze bottles for edible substances, such as ketchup or honey, or for home- and bodycare products.
  • a tamper-evident feature is required to evidence the first time opening of the lid or tampering with the closure.
  • a tamper-evident strip (TE-strip) is formed which is connected to the closure body or the lid by frangible connections and which engages behind a locking edge or member on the lid or closure body to prevent opening of the lid without removing the tamper-evident strip.
  • a disadvantage of such a tamper-evident solution is that the TE-strip is removed from the closure at first time opening of the closure and the user has to dispose of the loose plastic part.
  • Such loose relatively small plastic parts pose an environmental problem, because they end up way too often in the environment instead of in a garbage bin and pollute nature.
  • tamper-evident solutions in which the tamper-evident feature does not produce a loose part.
  • One of such closures known in the art has a tamper-evident push-button, which is held in or on the closure when the lid is opened for the first time. Examples of this type of closures are found in EP 1174359 A2, JP 3628835 and JP 2007045421, wherein a pushbutton button is formed in one piece with the closure body.
  • JP 2007045422 shows a solution in which a separately formed button is locked in the closure body.
  • JP 3320898 discloses a closure wherein a tamper-evident push-button is formed on the hinging lid.
  • the push-button is connected to the lid by frangible connections.
  • the push-button is held in a recess in the closure body by a hinging protrusion.
  • the frangible connections are broken and ridges, provided on the inner side of the pushbutton, are snapped in grooves at the recess to retain the button in the pushed-in position.
  • a protrusion keeps the push-button in the recess. The push-button is thus held in the recess in a pushed-in state once it has been pushed once.
  • This known closure is integrally moulded from a synthetic resin, in a state that is shown in Figures 6 and 7 of JP 3320898.
  • the push-button extends transverse to a skirt of the lid.
  • the push-button is swivelled to an orientation in which it can be received in the recess.
  • the push-button has to be forced with a lower end beyond a protrusion at the lower end of the recess, which prevents that the lower end of the push-button can escape from the recess after first time closing.
  • a disadvantage of this known structure is the risk that the frangible connections get damaged upon forcing the push-button in the ready-to-use position in the recess.
  • Another disadvantage is that in practice the snap mechanism may not work reliably, because the push-button deforms due to the push force and may hamper proper snapping.
  • the invention has for an object to provide a dispensing closure which has less risk to be damaged when it is made ready to use.
  • a dispensing closure for a container, wherein the closure comprises a closure body having a deck and a circumferential skirt. A dispensing orifice is formed in the deck and a receiving recess is formed in the circumferential skirt. The receiving recess has an open deck-sided end.
  • the dispensing closure furthermore comprises a lid which is hingedly connected to the closure body, wherein the lid has a closed state in which it covers the dispensing orifice and at least a part of the deck, and has an open state in which it is swivelled away from the deck about a hinging axis, such that a product can be dispensed from the container through the dispensing orifice.
  • the dispensing closure comprises furthermore a tamper-evident push-button formed in one piece with the lid, wherein the lid and the push-button are connected by frangible connections.
  • the tamper-evident push-button is received in the receiving recess upon first time closing of the lid.
  • the receiving recess is adapted to allow the tamper-evident push-button to be pushed/moved whilst in the receiving recess so as to break the frangible connections and allow opening of the lid.
  • the push-button While the pushbutton is connected to the lid by the frangible connections, the push-button is configured and oriented or orientatable such that upon first time closing of the lid, the push-button is insertable in the receiving recess from said open deck-sided end.
  • the push-button When the dispensing closure according to the invention is moulded, the push-button is already in an orientation with respect to the lid, in which it will eventually be in its final position in the receiving recess, or, alternatively it is in an orientation offset, preferably at most 30° from the orientation it will eventually be in in its final position in the receiving recess.
  • the structure of the closure according to the invention is such that the push-button can be brought from above in the receiving recess in the orientation in which it was moulded with respect to the lid, or only has to be pushed inwardly over a limited angle, preferably a maximum angle of 30° before the push-button can be brought in the receiving recess from above.
  • an embodiment with an inclination outward with respect of the skirt of the lid i.e. with an angular offset of at most 30°, as mentioned above, requires a simpler injection mould. There is no need for a slider (a moveable mould part) in the injection mould to form a lid that can be released from the mould cavity.
  • the push-button has a coupling member to couple the push-button to the closure body, said coupling member being located opposite the frangible connections, and the recess has an end opposite the deck-sided end, which is adapted to receive the coupling member.
  • the coupling member and the frangible connections are thus located on opposite ends of the push-button, such that when the coupling member is moved in the corresponding (lower) end of the recess upon first time closing of the lid, the resistance that the button meets is directed upwardly, such that there is no transverse load induced in the push-button which would introduce transverse forces or bending moments in the frangible connections.
  • the coupling member provides a tilting axis allowing tilting movement of the push-button with respect to the closure body when it is pushed in.
  • the push-button With the closure and container in an upright position, the push-button can be pushed near an upper end thereof, thus near the frangible connections to break them, while the hinging point is at a lower end and allows the push-button to swivel inwardly.
  • the coupling member is formed as an anchor pin having at least one transverse retaining lug, and the corresponding end of the recess includes an opening allowing insertion of the anchor pin, and wherein upon insertion of the anchor pin in said opening, the transverse retaining lug gets caught behind an edge of said opening and prevents the anchor pin to be retracted.
  • the transverse retaining lug(s) can move, e.g. bend slightly inwards when it is passed through the opening and then snaps back behind the edge of the opening like a barb.
  • the coupling member has two transverse retaining lugs which form a tapering shape. The tapering shape facilitates the insertion of the coupling member in the opening at the end of the recess.
  • retaining means are provided adapted to retain the push-button in a pushed-in state in the receiving recess after first time opening.
  • the retaining means comprise a clamp ridge in a central region of the recess seen in a width direction, and wherein a protrusion is formed on a central region of a rear surface of the push-button, seen in the width direction, wherein the clamp ridge and the protrusion are configured an arranged to cooperate and retain the button in a pushed-in state, preferably by friction.
  • the feature that the protrusion and the clamping ridge are located in a central region of the recess and the push-button, and the feature that the retainment is based on clamping/friction, has the beneficial effect that minimal deformation occurs in the push-button when it encounters resistance from the protrusion engaging the clamping ridge, because the pushing force, like the resistance, is mainly applied in the middle of the push-button.
  • the push-button will be brought in a pushed-in position and it is warranted by the arrangement according to this embodiment that it is held there.
  • the clamp ridge is formed by a support rib formed in the central region of the recess.
  • the retaining means may comprise two support ribs in the central region of the recess, said support ribs being spaced apart.
  • Two protrusions may be formed on the rear surface of the push-button, each arranged and adapted to engage one of the support ribs.
  • the lid is connected to the closure body by a hinge that is located opposite the push-button.
  • the closure body and the lid are made in one piece.
  • the hinge may then be a living hinge or bi-stable hinge.
  • the lid and the push-button are made in one piece.
  • the dispensing closure is a one-piece injection moulded part.
  • the lid has a peripheral rim which in the closed state is flush with the circumferential skirt. This gives the closure a nice and smooth appearance in the closed state.
  • the invention also relates to an assembly of a dispensing closure as described in the above and a container holding a substance to be dispensed.
  • Substances that can typically held are edible substances like sauces, ketchup, honey.
  • Other substances that can be held in the container are bodycare or haircare products like shower gel, shampoo, hair conditioner etc.
  • Other possible products are homecare or cleaning products.
  • the invention also relates to a method for manufacturing a dispensing closure as described in the above.
  • the method comprises the following steps:
  • the dispensing closure is moulded in the open state, wherein the tamper-evident push-button is formed while having an orientation in a tangential direction with respect to the intended movement of the lid about the hinging axis,
  • the lid is closed by swivelling the lid about the hinging axis from the open state to the closed state, wherein the push-button is inserted in the recess from an open upper end of the recess.
  • the tamper-evident pushbutton is received in the receiving recess upon first time closing of the lid, wherein the receiving recess is adapted to allow the tamper-evident push-button to be pushed whilst in the receiving recess so as to break the frangible connections and allow opening of the lid,
  • the pushbutton is configured and oriented or orientatable such that upon first time closing of the lid and the lid is swivelled about the hinging axis from the open to the closed state, the pushbutton is insertable in the receiving recess from said open deck-sided end, as is described in the above for a dispensing closure can also be used in closures having basically the same structure as the dispensing closure, i.e.
  • closures to be arranged on containers containing powdered or granular products, such as for example infant formula, powdered milk etc.
  • closures basically have an annular base, i.e. the closure body, which is attached to an upper side of the container, which may for example be an open top can.
  • the annular base that is attached or to be attached to the container defines an access opening through which content of the container, e.g. infant formula, can be taken from the container.
  • the lid is hingedly connected to the annular base and covers the opening in a closed state. In an open state the opening is free and product can be taken from the container via the opening.
  • Such closures are commonly made of a plastics material by injection moulding.
  • the invention also relates to a closure for a container, said closure comprising:
  • closure body having a deck and a circumferential skirt, wherein the closure body defines an opening
  • a lid which is hingedly connected to the closure body, the lid having a closed state in which it covers the opening and the deck, and having an open state in which it is swivelled away from the deck and opening about a hinging axis, such that a product contained in the container can pass through the opening,
  • the tamper-evident push-button is positioned in or over the receiving recess upon first time closing of the lid, wherein the receiving recess is adapted to allow the tamper-evident push-button to be pushed into the receiving recess so as to break the frangible connections and allow opening of the lid, and
  • the push-button has a coupling member to couple the push-button to the closure body, wherein the coupling member provides a tilting axis allowing tilting movement of the push-button with respect to the closure body when it is pushed in.
  • closures can be dispensing closures having a dispensing orifice as described in the above, for example for dispensing fluid substances, or closures of the above-mentioned type to be arranged on containers containing powdered or granular products, having an opening through which the product can be taken from the container.
  • an attachment surface is formed in the recess and the coupling member is welded to the attachment surface after first time closing of the lid.
  • the tilting axis is provided by a hinge, preferably a film hinge, that interconnects the push-button and the coupling member.
  • the coupling member is formed as an anchor pin having at least one transverse retaining lug

  • inner skirt 22 On the inner side of the closure body 2 a so called inner skirt 22 is formed, which extends from the deck 5 coaxially with dispensing orifice 6.
  • This inner skirt 22 is only partly visible in Fig. 5, but is a common feature adapted to allow the closure to be arranged and secured on a neck of the container, usually by some kind of snap structure.
  • the closure body 2 furthermore comprises an outer skirt 8, which is a circumferential skirt that extends from the deck 5.
  • the outer skirt 8 thus has an oval contour.
  • the skirt 8 has a free end 9, which in an upright position of the closure 1 will be the lower end, and adjoins the container wall when arranged on the container.

  • the transverse retaining lugs 20 have a slanting surface which guides them past the respective edges of the opening 13. They form a tapering shape which is best seen in Fig. 4 which tapering shape facilitates insertion of the anchor.
  • the transverse retaining lugs are also sliding by the slightly slanting support ribs 11 , such that the anchor of the coupling member is guided towards the opening 13.
  • the closure 1 is made by an injection moulding process, which allows it to be produced in large quantities by the industry. After the closures 1 are moulded they are ejected from the mould in the open state as is shown in Figs. 1 and 3. The closures 1 will be closed by an automated device such that they are in a state in which they are ready to be placed on a container.
  • the configuration and arrangement of the open end 10A of the recess, the support ribs 11 , the opening 13, and the coupling member 18 having an anchor pin 19 and transverse retaining lugs forming an anchor shaped end facilitates the automated closing process of the closure 1.
  • the configuration and arrangement is such that the frangible connections 17 are spared as much as possible during first time closing of the closure, whilst the coupling member 18 is securely fixed to the closure body 2 and is practically irremovable without causing visible damage to the closure 1.

  • the protrusions 21 are spaced apart and positioned such that they are each located in the space separating the support ribs 11 when the push-button 16 is pushed in, wherein each protrusion engages one rib 11 such that friction occurs between a so called clamping ridge of the respective ribs 11 and the respective protrusions 21.
  • the protrusions 21 and the support ribs 11 thus constitute retaining means whereby the push-button 16 is retained in the pushed-in position, once it is pushed in the first time.
  • the push-button 16 clearly shows that the tamper-evident closure 1 has been opened before.
  • the slanting supporting ribs 11 allow the push-button to move inwardly at the deck sided end, where the frangible connections 17 are formed on the push-button. At the opposite end (lower end) of the support ribs 11 the push-button 16 cannot move inwardly.
  • the push-button 16 swivels inwardly around a swivelling axis defined by the transverse retaining lugs 20 engaging behind the lateral edges of the opening 13, when it is pushed in the first time. Once pushed in, the frangible connections 17 are subjected to transverse forces which will break them.
  • the cooperation between the protrusions 21 and the support ribs 11 maintains the push-button 16 in this inwardly swivelled position.
  • the open recess 10 with only two support ribs 11 at the rear saves material and is possible because the push-button 16, that is received in the recess 10 when the closure 1 is closed will cover the recess 10 in the unused state but also in the pushed-in state.

Abstract

Une fermeture (1) comprend un corps de fermeture (2) ayant un plateau (5) et une jupe circonférentielle (8). Une ouverture (6) est formée dans le plateau et un évidement de réception (10) est formé dans la jupe circonférentielle ou dans le plateau. La fermeture comprend en outre un couvercle (3) qui est articulé au corps de fermeture. La fermeture comprend en outre un bouton-poussoir inviolable (16) formé d'un seul tenant avec le couvercle, le couvercle et le bouton-poussoir étant reliés par des liaisons cassantes (17). Le bouton-poussoir inviolable est reçu dans l'évidement de réception lors de la fermeture du couvercle pour la première fois. L'évidement de réception est conçu pour permettre au bouton-poussoir inviolable d'être poussé tout en étant dans l'évidement de réception de façon à rompre les liaisons cassantes et permettre l'ouverture du couvercle. Le bouton-poussoir comporte un élément d'accouplement (18) pour accoupler le bouton-poussoir au corps de fermeture. L'élément d'accouplement fournit un axe d'inclinaison permettant un mouvement d'inclinaison du bouton-poussoir par rapport au corps de fermeture lorsqu'il est poussé.
