A cap for a bottle or the like has means, such as a screw-thread, for cooperating with an opening in the bottle or the like in order to seal the contents of the bottle or the like. The cap has a container (2) which is adapted to hold a fluid material, such as a cordial concentrate or milk, and/or one or more solid objects, such as tablets or sugar. The container (2) has a releasable lid (6) and may contain a canister (4) having a lid (5). The bottom of the container (2) has a lower chamber which may be closable by a blanking lid (12). The bottle may take the form of an insulated flask adapted to contain hot or cold water.

This invention relates to improvements in caps for bottles and the like.

According to the invention, there is provided a cap for a bottle or the like, said cap having means for co-operating with an opening in the bottle or the like in order to seal the contents of the bottle or the like and said cap further having a container adapted to hold a fluid and/or one or more solid objects and means for gaining access to the interior of the container, wherein the container is provided with a bottom and wherein a lower chamber is provided in the bottom of the container.

According to one embodiment of the invention, the cap may be provided with a screw-thread which is adapted to engage with a co-operating screw-thread on a bottle or the like for which the cap is intended.

Alternatively, the cap may be a push-fit in the opening of the bottle or the like for which the cap is intended.

The container in the cap may be provided with a releasable lid by means of which the contents of the container can be accessed and the container then reclosed.

The lid may be a simple push-fit into the cap or it may be provided with a screw-thread which is adapted to engage with a co-operating screw-thread provided at an opening to the container.

Desirably, the container is adapted to project into an opening in the bottle or the like when the cap is in position on the bottle or the like.

The lid may be provided with a slot to facilitate removal of the lid from the container.

Preferably, the container is adapted to hold a canister containing a fluid material such as a cordial concentrate. Alternatively, the container may be adapted to contain one or more solid objects such as tablets.

According to a preferred embodiment of the invention, the lower chamber is provided with an internal screw-thread and a blanking lid is adapted to engage with the internal screw-thread in the lower chamber, said lower chamber then serving to contain a fluid material or one or more solid objects when the blanking lid is screwed into the lower chamber.

An ice bottle or a flexible container having chemical heating means when pressed may be adapted to be screwed into the lower chamber.

Preferably, the container has an outer wall defining the lower chamber and the outer wall may be provided with a groove adapted to receive an O-ring or seal.

Part of the exterior surface of the cap is preferably provided with a series of knurls to facilitate removal of the cap from a bottle or the like to which the cap has been secured.

The cap is desirably made of stainless steel or of a synthetic plastics material.

The invention will now be described in detail, by way of example, with reference to the drawings, in which:-

In the drawings, like parts are denoted by like reference numerals.

Referring to the drawings, the cap according to the invention comprises a main body 1 which is formed integrally with the outer wall of a container 2. The outer diameter of the container 2 is such that it can fit into the neck of a bottle for which the cap is intended. The neck of the bottle (not shown) is intended to fit between the outside of the container 2 and the inside of the main body 1. The interior surface of the main body 1 is preferably provided with an internal screw-thread (not shown) for engagement with a corresponding external screw-thread on the outer surface of the neck of the bottle. The exterior surface of the main body 1 is provided with a series of knurls 3.

The container 2 projects beyond the upper end of the body 1 and is adapted to contain a canister 4 having a lid 5. The canister 4 is held in the container 2 by a cap lid 6 which has an internal screw-thread for engagement with a cooperating screw thread 8 on the projecting end of the container 2. The cap lid 6 is provided with a groove 7 in its upper surface to facilitate removal of the lid from the container.

The bottom of the container 2 is provided with a lower chamber 9 having an internal screw-thread (not shown). The outer wall of the container 2 defining the chamber 9 is provided with a groove 10 which is adapted to receive an O-ring or seal 11. In normal use, a blanking lid 12 is screwed into the chamber 9 as shown in Figs. 1 to 3 of the drawings. However, if desired, the blanking lid 12 may be removed and replaced by an ice bottle 13 as indicated in Fig. 6 of the drawings.

As indicated above, the canister is intended to be filled with a cordial extract or tablets and the bottle for which the cap according to the invention is intended will normally be filled with water. The contents of the canister can be poured into the bottle to provide a refreshing drink.

The ice bottle shown in Fig. 6 will be the kind readily obtainable and precooled in a freezer or refrigerator. It is preferred in such cases to use a bottle in the form of an insulated flask. The ice bottle could also be replaced by a flexible container having chemical heating means when pressed. In that way, a heated beverage can be obtained from the bottle or flask and the canister could contain milk and/or sugar.

The cap according to the invention may be made of any suitable material but stainless steel or a synthetic plastics material are preferred. The cap may have substantially the same diameter as the bottle for which it is intended or it may have a smaller diameter for a bottle with a reduced diameter neck portion.

The invention is not restricted to the above described embodiment but modifications and variations may be made without departing from the scope of the invention. For example, an ice cap could be inserted into the chamber 9 and held therein by the blanking lid 12. Alternatively, an ice bottle could be formed integrally with the container 2 so that the ice bottle is not detachable from the cap.
