Full Text	This invention relates to a tamper-proof cap for a container and a container therefor. Containers for supplying goods such as potable water are provided with caps and it is desirable that such caps are made tamper-proof to eliminate adulteration between the point of manufacture and the point of supply to the consumer. This invention therefore proposes a simple and effective tamper-proof cap for a container which can be readily installed in place to lock the cap with the container, the lower portion of the cap, however, being manually tearable from i ts upper portion, to leave the upper portion for covering the mouth of the container. In order to enable to said lower portion of the cap to be manually torn away from its upper portion, it is preferred to have the cap made of a material which allows the 1atter portion to be torn away from the former. Thus, for instance, the cap can be made of piastic, for rendering the same sufficiently flexible to permit the lower portion to be torn of f , the upper portion being sufficiently rigid to be retained on the neck of the container for covering its mouth. Since the cap, when once opened cannot be restored to its original locked condition, adulteration of the contents of the container is eliminated- At the same time unlocking the cap from the container is a simple procedure, at the user end, because all that one has to do is to manually grip a tag provided for the lower portion of the cap and tear the lower portion away from the upper portion. The latter portion of the cap can be used in the normal way for covering and uncovering the mouth of the container. Empty containers, after use, can be sent back to the pi ace of manufacture for being cleaned, refilled and fitted with fresh caps locked to the containers, which if opened, before they reach consumers, would indicate that they have been tampered with. Various other features of the tamper-proof cap and container proposed herein would be apparent from the following further description thereof given hereunder. According to this invention, the tamper-proof cap for a container comprises an upper portion snugly seatable on, and around, a raised perinietral boss provided on the exterior of the neck of the container; a lower portion having on its interior a perinietral ridge seatable in, and around, a waist provided on the exterior of the said neck, to form a tight snap-fit therewith and thus lock the cap to the container, said waist being located below the said boss; a manually grippable tag provided for the lower portion of the cap, for enabling the said lower portion to be manually torn off the upper portion, leaving the said upper portion in place, on and around, the said boss, for covering and uncovering the said mouth. This invention will now be described with reference to an embodiment thereof which is illustrated by way of example in the accompanying drawings wherein Figs.l and 2 respectively illustrate the cap in top pi an view and in sectional elevation before the lower portion thereof is torn off Figs.3 and 4 respectively i1lustrate the cap in top pi an view and sectional elevation after the lower portion thereof is torn off Fig. 5 i1 lustrates the torn strip relating to the lower portion of the cap Fig,6 illustrates the view at AA in Fig.5 Fig.7 illustrates the neck of the container without the cap Fig.8 illustrates the neck of the container with the cap locked in place and Fig.9 illustrates the neck of the container and the upper portion of the cap in place after the lower portion of the cap has been torn off. The neck N contents of the said container, The said neck, on its exterior, has a waist W surmounted by a raised boss B. The upper portion of the cap C at U is snugly seatable on, and around, the boss B, The lower portion of the cap C at L, has on it® interior, a perimetral ridge R seatable in, and around, the waist W, to lock the said cap to the container- The locking of the cap to the container is achieved by thrusting the cap over and down the neck of the container, until the ridge slips into the waist and forms a tight snap-fit therewith. Once so fitted, the cap is practically irremovable by reason of the snap-fit engagement between the ridge R and the waist W. The said lower portion of the cap, on its exterior, is provided with a manually grippable tag T for enabling the said lower portion to be manually torn away from the said upper portion, thus leaving the said upper portion on, and around, the said boss, to cover the mouth 0. To facilitate a firm manual grip, the tag is serrated at S. Preferably, the cap, on its interior, is provided with an annular plug for securely engaging with the mouth 0 and serving as a stopper.

Since the cap, when once opened cannot be restored to its original locked condition, adulteration of the contents of the container is eliminated- At the same time unlocking the cap from the container is a simple procedure, at the user end, because all that one has to do is to manually grip a tag provided for the lower portion of the cap and tear the lower portion away from the upper portion. The latter portion of the cap can be used in the normal way for covering and uncovering the mouth of the container.
Empty containers, after use, can be sent back to the pi ace of manufacture for being cleaned, refilled and fitted with fresh caps locked to the containers, which if opened, before they reach consumers, would indicate that they have been tampered with.
