Definitions

• the invention relates to a cap to be fixed, for example by screwing or hooking, on a container neck, in particular on a bottle neck containing a liquid, particularly drinks.
• This type of plug allows easy closure and opening on the part of the user.
• This type of stopper generally comprises three main elements, namely a main body which is screwed onto the neck of the bottle, a closure element and a protective cover. Functionally, it is for the user to be able to move from a state (open for example) to another state (closed for example) in a simple manner, by intervention of the mouth or one hand, with moreover a controlled flow of the liquid. Athletes in particular find here an interest in that they can drink while continuing their physical activity. Young children can favorably use containers equipped with such caps because their handling is very easy and the flow of liquid is controlled.
• this type of cap comprises at least one so-called tamper-evident ring intended to ensure that the cap has never been opened before its first use.
• a first tamper (or security) ring may be provided between the base of the main body and the neck of the bottle. This ring prevents the opening of the bottle by said base which is generally screwed on the neck, and is connected to said base by breakable bridges regularly spaced apart and separated from each other by incisions.
• a second tamperproof ring is further provided between the cover and the main body, more precisely between the distal end of said cover and the base. of the tubular projection through which the liquid can escape.
• This ring is intended to ensure that the cap has never been disconnected from the cap and therefore the bottle has never been opened by removing the cap.
• the ring is internally provided with longitudinal protuberances that is to say oriented parallel to the axis of the plug, which cooperate with grooves oriented in the same direction and which are provided for example on a specific cylindrical wall the main body of the cap.
• the second ring generally provided on the caps is connected to the distal end of the hood by breakable bridges regularly spaced and separated from each other by incisions.
• breakable bridges regularly spaced and separated from each other by incisions.
• EP 1 065 150 A1 discloses a plug of the type mentioned above; only the functionality of the rings is described in this document so that one can think that they are in the form indicated above; in any case the problem stated above is neither suggested nor disclosed in this prior art.
• the invention aims to overcome the disadvantages of the state of the art and in particular the problem of the unwanted rotation of the warranty ring or rings simultaneously with the element (hood or main body) to which they are related to the 'origin.
• a cap to be fixed on a liquid container neck comprising:
• a main body internally provided with a connecting means with said neck and surmounted by a tubular projection having an outer wall defining a reference axis;
• said ring is provided with teeth shaped so as to cooperate with regularly spaced complementary profile protuberances provided on a proximal end of the main body, the teeth and / or the protuberances having a chamfered prismatic profile.
• the teeth of said ring are oriented so that their chamfered portion is directed towards the proximal end of said main body.
• Such an orientation of the chamfered portion advantageously allows to guide the teeth of the ring relative to the protuberances of the main body, during assembly when the cover is close to the main body parallel to the axis of the cap. This facilitates the installation of the cap on the main body of the cap during assembly of these parts, without risk of damage to the elements in contact.
• the teeth of the ring comprise a plurality of chamfered walls located in the distal portion.
• the prismatic profile of the teeth of the ring is such that the teeth have two mutually parallel surfaces, each forming part of a cylindrical or substantially cylindrical surface.
• the ring has an outer diameter greater than the outer diameter of the hood. Furthermore, said cap further comprises an outer wall provided with at least one zone facilitating its gripping. It is indeed important that the user can grab the hood easily and reliably, even with wet hands for example. For children it is also important that they can grab the hood as easily as possible.
• One solution may be that the outer wall of the cover comprises several flats.
• Figure 1 is a partially broken perspective view of the plug according to one embodiment of the invention.
• Figure 2 is a partial perspective view of the protuberances of the main body; and - Figure 3 is a partial perspective view of the teeth of the ring according to a preferred embodiment of the invention.
• the plug as a whole can be considered as axisymmetric and it comprises a main body 1 internally provided with a connecting means (not visible) with the neck of the container (no shown) containing a liquid.
• the main body of the cap is surmounted by a tubular projection 2 which has an outer wall defining a reference axis XX.
• a cover 3 covers the tubular projection 2, preferably closer to the tubular projection 2.
• the cover 3 is internally provided with elastic attachment means on the tubular projection 2, preferably on the basis of said projection 2.
• the attachment means may be in the form of an annular inner groove which cooperates with a retaining flange disposed on the base (or proximal part) of the tubular projection 2. Any other elastic attachment means can be retained without departing from the scope of the invention.
• a tamper evident ring 4 is provided, disposed in the distal extension of the cap 3 to which it is connected in a known manner, by breakable bridges 5 regularly distributed and separated from each other by incisions.
• the breakable bridges 5 are thus provided at one end of the ring adjacent to the distal end of the hood 3.
• the ring 4 has teeth 6 which cooperate with protuberances 7 provided on a proximal end of the main body 1.
• the protuberances are here arranged in a plurality of angular sectors in an arc of a circle, and their profile is shaped so to cooperate as soon as the plug is assembled, with a chamfered prismatic profile of the teeth 6 of the ring 4.
• the protuberances 7 may be arranged in a complete circle.
• the number of protuberances is generally quite high and preferably greater than 10.
• protuberances 7 have a double slope inclined 9, 10 which cooperates directly with chamfers 11, 12 formed at the distal end of the teeth 6.
• This double slope 9,10 provides guidance 6 teeth vis-à-vis the protuberances 7 during the bonnet assembly on the main body of the cap. This avoids damaging these elements, many small, so relatively fragile.
• the teeth 6 have a "root" or anchoring in the ring 4 having a larger section than that of their tapered distal end; in other words, the chamfered ends of the teeth 6 are oriented towards the proximal end of the main body 1.
• the teeth 6 are chamfered in several planes: two chamfers 11, 12 are made in two planes forming an acute angle, at the distal end of the teeth 6.
• the set of 11, 12 forms a tapered tip at the distal end of the teeth 6, which corresponds and cooperates with a conjugate form of the protuberances 7.
• the protuberances 7 may be chamfered and the teeth 6 then have a complementary profile, for example beveled but not necessarily chamfered.
• the cover 3 may have a specific outer wall, for example provided with at least one zone 15 to facilitate gripping.
• the outer wall of the cover 3 may have several flats 15; the flats 15 may have a high roughness, greater than that of the rest of the outer wall of the cover 3.
