A closure for an ampoule, the closure comprising: a cap portion arranged to engage with a broken neck of an opened ampoule; and a cylindrical skirt portion extending from the cap portion, the skirt portion being elastically deformable and being arranged to move from a first position in which it is at least partially folded back on itself to a second position in which it is unfolded and extends away from the cap portion. The closure can close off an opening such as that formed in an ampoule when the neck is snapped and the top removed. As the cap portion engages with the broken neck, it reduces the chances of users receiving lacerations from the sharp edges. The cap portion also seals the ampoule, preventing the contents from being spilled and/or wasted. The closure also provides a degree of impact protection, reinforcement and strengthening to the now weakened open end of the ampoule, e.g. in case the ampoule is dropped. The skirt portion not only provides a seal around the ampoule body by being in close contact therewith, but also holds the cap portion firmly against the broken rim of the open ampoule, thus holding the closure in place by means of the friction between the skirt portion and the outer surface of the ampoule body.
A closure for an ampoule, the closure comprising:
A closure as claimed in any preceding claim, wherein the surface of the cap portion inside the skirt portion comprises a projection, preferably having a cone shape.
A closure as claimed in any preceding claim, wherein the underside of the cap portion inside the skirt portion is formed from a deformable material.
A closure as claimed in any preceding claim, comprising a channel extending through the cap from a lower surface of the cap inside the skirt portion to an upper surface of the cap.
A closure as claimed in any preceding claim, wherein the cap portion and skirt portion are integrally formed.
A closure as claimed in any preceding claim, wherein the cap portion and the skirt portion are formed from an elastomer, preferably silicone.
A closure as claimed in any preceding claim, wherein the skirt portion is transparent.
A closure as claimed in any preceding claim, wherein the cap portion comprises shaping on its exterior surface that inhibits rolling when the skirt is in the second position.
A closure as claimed in any preceding claim, wherein the interior surface of the skirt is coated at least in part with a gripping material or an adhesive.
A closure as claimed in any preceding claim, wherein the interior surface of the skirt is provided with at least one circumferential rib.
A closure as claimed in any preceding claim, further comprising a ring positioned circumferentially around the closure and around which the skirt portion is rolled or folded when in the first position.
A closure as claimed in any preceding claim, wherein the cap portion further comprises a gripping device arranged to be capable of gripping a break off a top of an ampoule to facilitate removal of the top from the rest of the ampoule.
A closure as claimed in any preceding claim, further comprising a lid arranged to cover the upper surface of the cap portion.
A closure as claimed in any preceding claim, further comprising a shield rib separating the skirt portion from an upper surface of the closure.
A closure as claimed in any preceding claim, wherein the skirt portion comprises one or more support projections positioned such that when the skirt portion is in its second position the support projections engage with the outer surface of the ampoule in the region of a shoulder of the ampoule.
A closure as claimed in any preceding claim, further comprising one or more air channels that, in use, connect the outside of the ampoule to the inside of the ampoule, said channels preferably comprising a filter.
