The invention relates to a closure for a bottle. The invention also relates to an assembly of such a closure and a bottle. The invention further relates to a method for assembling such an assembly.
Already known since 1891 are closures particularly for making possible medium-tight closure of a drink container for the purpose of enabling durable conservation of drink stored in the drink container, usually in bottles. The cap can be removed from the bottle by means of a bottle-opener or other suitable tool, after which the drink can be consumed. The drawback of the conventional closure is that removal of the closure is generally only possible by making use of a separate tool, such as a bottle-opener, suitable for the purpose.
The American U.S. Pat. No. 6,158,604 describes an improved closure for a bottle manufactured from plastic, comprising a closing element provided with a number of clamping elements adapted to engage on an outer side of the neck of the bottle. The closing element is here also provided with an external screw thread. The known closure also comprises a securing element arranged on the closing element to enable selective securing and release of the clamping elements. The securing element is provided for this purpose with an internal screw thread adapted for co-action with the external screw thread of the closing element. The orientation of the securing element relative to the closing element can be changed by rotating the securing element axially relative to the closing element, whereby the securing element can secure or release the clamping elements to enable respectively closing or opening of the bottle. Although the known closure can be removed from a bottle relatively easily by a consumer without making use of separate tools, the known closure also has a number of drawbacks. A significant drawback of the known closure is that the construction of the closure is relatively bulky, and therefore robust. Research has shown here that the relatively bulky closure arouses consumer aversion, and is therefore not accepted, or hardly so.
The invention has for its object to provide a relatively compact closure for a bottle.
The invention provides for this purpose a closure of the type stated in the preamble, comprising: a closing element provided with a number of clamping elements adapted to engage on a neck of a bottle, this closing element also being provided with coupling means, and a securing element connected to the closing element and provided with locking means for the clamping elements, this securing element also being provided with counter-coupling means adapted for co-action with the coupling means for the purpose of connecting the closing element to the securing element, wherein the coupling means and counter-coupling means are adapted to be substantially received in the neck of the bottle, and wherein the coupling means and counter-coupling means are adapted to limit the relative displacement of the securing element relative to the closing element, and wherein the orientation between the closing element and the securing element can be changed between a released position, in which the locking means leave the clamping means substantially unobstructed, and a secured position, in which the locking means substantially lock and thereby substantially fix the clamping means. When the closure according to the invention is arranged on a neck of a bottle, the coupling means will generally be located substantially in the neck of the bottle in both the secured and the released position, while the counter-coupling means are generally located substantially in the neck of the bottle in the secured position and at least partially outside the neck of the bottle in the released position. By in fact realizing the coupling between the closing element and the securing element substantially in the neck of the bottle instead of outside the neck of the bottle, the volume occupied by the closure according to the invention can be reduced substantially relative to the volume occupied by the known closure. A material-saving can also be realized due to the relatively efficient construction of the closure according to the invention, this being favourable from an economic viewpoint. The relatively compact, slender design of the closure according to the invention will moreover be more readily accepted by consumers. Another significant advantage of the closure according to the invention is that the closure can close a bottle in relatively reliable manner. The closure known from the prior art has the drawback that the coupling means and the counter-coupling means formed by the threaded connection are situated outside the bottle. If the temperature increases, the closure manufactured from plastic will expand relative to the bottle, whereby the bottle can no longer be closed in reliable manner. By positioning the coupling means and counter-coupling means of the closure according to the invention substantially in the neck of the bottle in at least the secured position, the coupling means and the counter-coupling means will expand less strongly in the case of fluctuations in the temperature in the atmosphere surrounding the bottle since the coupling means and the counter-coupling means are positioned within an environment which is insulated to some extent by the bottle. If the temperature in the bottle increases, the coupling means and the counter-coupling means will moreover be able to expand possibly as far as an inner side of the neck of the bottle and thereby possibly engage more closely on the inner side of the neck of the bottle, thereby guaranteeing a reliable closure of the bottle. Similarly to the known closure, the closure according to the invention can be operated in relatively simple manner by a consumer without a separate tool here being required. It is noted that bottle must be interpreted relatively broadly in the context of this patent, wherein any other container, in particular foodstuff container, more particularly drink container, provided with a neck of any form whatever is also deemed to be a bottle in the present situation. The bottle will however generally be formed by a conventional drink bottle made of glass and/or plastic, this drink bottle comprising a body and a narrower neck connected to the body. A further significant advantage of the closure according to the invention is that the coupling means and the counter-coupling means are adapted to limit the displacement of the securing element relative to the closing element (and vice versa), whereby unintentional release of the securing element relative to the closing element can be prevented. In this way the securing element will thus remain connected non-releasably to the closing element. The limiting of the relative displacement of the closing element and the securing element can relate to an axial displacement and/or to a rotating displacement of the securing element relative to the closing element. The limiting of the maximal displacement of the securing element relative to the closing element can be realized in diverse ways, wherein one or more stops are usually applied. Diverse preferred embodiments for limiting the securing element relative to the closing element will be described hereinbelow.
The closing element will generally function as inner cap and the securing element will function as an outer cap co-acting with the inner cap. By displacing and preferably (axially) rotating the outer cap relative to the inner cap the closure can be brought into the secured position or into the released position. The coupling means and the counter-coupling means are more preferably formed here by a threaded connection, wherein the coupling means comprise a screw thread and the counter-coupling means comprise a counter-screw thread. A threaded connection is relatively strong and durable, whereby the closure can be brought into and held in relatively reliable manner in the secured position or released position. It will be apparent that another type of connection, such as for instance a bayonet coupling (bayonet fitting) or a snap connection, can also be used in addition to a threaded connection. Both the threaded connection and the bayonet coupling, as well as the snap connection, are or at least can be adapted to limit the maximum displacement of the securing element relative to the closing element in order to prevent undesired removal of the closure according to the invention. In general the securing element will ultimately be displaceable with a substantially linear movement relative to the closing element in order to allow relatively efficient engagement of the locking means on the clamping elements in the secured position and to allow positioning of the locking means substantially at a distance from the clamping elements in the released position.
In a preferred embodiment the closing element comprises a tubular element provided with the coupling means, this tubular element being adapted to receive a part of the securing element provided with the counter-coupling means. When the closure is arranged on a bottle, the tubular element is positioned in the secured position at least partially, and preferably substantially in the neck of the bottle. The tubular element will generally be given a substantially cylindrical form and will generally be opened on one side (on a top side directed toward the securing element) in order to thus provide access to at least a part of the counter-coupling means. An inward directed side of the tubular element is preferably provided here with the coupling means. The counter-coupling means are preferably arranged on a protruding bush-like, more preferably cylindrical body forming part of the securing element, wherein the tubular element is more preferably adapted to receive at least a part of the bush-like body. An external side of the bush-like body is here preferably provided with the counter-coupling means. The bush-like body is more preferably adapted to receive at least one standing blocking element connected to the tubular element, which blocking element is provided with at least one first protrusion for limiting the relative movement of the securing element relative to the closing element. The securing element can be connected non-releasably to the closing element by limiting the relative displacement of the securing element relative to the closing element. The closure hereby remains permanently in the assembled position, whereby unintentional removal of the securing element from the closing element can be prevented. In order to limit the relative displacement of the securing element relative to the closing element in more reliable manner, it is advantageous that the bush-like body be provided with at least one second protrusion, wherein the first protrusion forms a stop for the second protrusion. When the closure is arranged on a bottle and the closure is situated in the released position, the closure as such can be removed from the bottle by pulling on the securing element in a direction away from the bottle, whereby both the securing element and the closing element connected (permanently) to the securing element can be removed from the bottle. The closing element and/or the securing element will generally be provided with at least one gripping member for a user. The gripping member can for instance be formed by a pull tab, but also by a profiling arranged on the closing element and/or on the securing element.
Since an (initial) underpressure or an overpressure may be present in the bottle, the closing element preferably comprises at least one ventilation opening. By means of applying one or more ventilation openings a pressure equalization can be realized by venting or bleeding between the pressure in the bottle and the pressure outside the bottle, after which the closure can be removed from the bottle with relatively little resistance. The securing element is more preferably adapted to close the ventilation opening in the secured position of the closure. The ventilation opening can be opened by displacing the securing element relative to the closing element in the direction of the released position, and venting or bleeding can take place. An alternative ventilation opening could be formed by a gap which is formed between the closing element and the neck of the bottle and which can be formed during displacement of the securing element relative to the closing element from the secured position (to the released position). The securing element can optionally close the ventilation opening in the secured position via a sealing element, whereby the ventilation opening can be closed in more reliable and durable manner.
In another preferred embodiment the closure comprises a breakable or otherwise removable seal connected to the closing element and/or the securing element, usually referred to as a tamper-evident provision, for the purpose of guaranteeing the content of the bottle for a consumer. During initial opening of the foodstuff container the seal will be discernibly, in particular visibly, and generally irreparably damaged by a consumer. The seal can be realized in different ways. It is for instance possible here to envisage the seal forming a breakable connection between the securing element and the closing element. It is however also possible for instance to envisage the seal forming a connection between the securing element and the bottle.
In order to be able to realize a substantially medium-tight closure of the bottle, it is advantageous that the closure comprises sealing means. The sealing means will here generally be manufactured from an elastic material, in particular an elastomer. The sealing means are generally adapted to allow the closing element to engage on the neck of a bottle via the sealing means, in particular a peripheral side of the neck of the bottle. In a particular preferred embodiment at least a part of the sealing means is adapted to engage on an inner side of the neck of the bottle in order to enable optimizing of the seal.
The clamping elements are preferably adapted for deformation during securing and/or release of the closure. The clamping elements are preferably manufactured for this purpose from an elastic material. It is also possible to envisage each clamping element being given a (to some extent) pivotable form, for instance by applying one or more weakening lines. Such a preferred embodiment makes use of the deforming capability of the clamping elements and provides for a rapid and efficient closing of the bottle. In a particular preferred embodiment the clamping elements comprise resilient clamping tongues arranged substantially in the peripheral direction of the closing element. A segmented (clamping) skirt is in fact created by positioning the clamping elements in the peripheral direction of the closing element. The clamping elements, and particularly the clamping tongues, can be adapted here to engage on a peripheral recess of the neck of the drink container. A durable and operationally reliable closure of the bottle can hereby be realized.
The closure according to the invention is preferably manufactured at least partially from at least one material chosen from the group of metals, metal alloys and plastics. Metal, in particular aluminium, and determined plastics are generally particularly suitable for use as closure to enable substantially medium tight closure of a bottle in relatively durable manner. A particularly suitable variant is obtained when the closing element is manufactured from an at least partially transparent plastic; and the securing element from a differently coloured plastic. The components from which the closure is constructed hereby become clearly apparent to a consumer. When the securing element is provided with a viewing opening, the content of the bottle moreover becomes visible via the applied transparent closing element.
The invention also relates to a closing element for use in the closure according to the invention. The invention further relates to a securing element for use in the closure according to the invention. It is possible to envisage both the closing element and the securing element being marketed separately. Advantages and preferred embodiments of the closing element and the securing element have already been described at length in the foregoing.
The invention also relates to an assembly of a bottle and a closure according to the invention connected to the bottle, wherein at least the coupling means are positioned substantially in a neck forming part of the bottle. The counter-coupling means are positioned substantially in the neck of the bottle in the secured position. The counter-coupling means will moreover be positioned at least partially outside the neck of the bottle in the released position in order to allow facilitated release of the clamping elements. The clamping elements here preferably engage on a peripheral side, and in particular outer side, of the neck of the bottle.
The invention furthermore relates to a method for assembling the assembly according to the invention, comprising the steps of: A) filling the bottle with a product, in particular a drink, B) arranging the closing element on a neck forming part of the bottle, and C) connecting the securing element to the closing element. In an alternative preferred embodiment step C) is performed before step B), whereby the closure according to the invention is first assembled before being arranged on the neck of the bottle. The method will usually also comprise step D), wherein step D) relates to cleaning of the assembly of the bottle and at least a part of the closure. The cleaning can take place here using a rinsing liquid, preferably water. The cleaning can take place after placing of only the closing element (step B) or after placing of the already assembled closure (step C).
