Description

TECHNICAL FIELD

The present invention relates to a locking mechanisms for containers including for instance child-safe locks.

BACKGROUND OF THE INVENTION

Certain food products, cleaning agents, medications and the like that are commonly found in the home may be dangerous to young children. Such substances must be transported and stored in containers having “child-safe” locking mechanisms for locking the lid of the container and which are difficult for children to open by means of challenging their cognition, dexterity and/or strength. Currently, existing child-safe locking mechanisms tend to utilise variations on one of a few common designs, such as the “push and twist” style cap. Whilst oftentimes effective, the prevalent use of this style of cap lock has become so widely used that children, of even younger ages, have become accustomed to them thus limiting their potential long-term effectiveness.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Preferred embodiments of the present invention will now be described herein with reference to FIGS. 1 to 4. The embodiments comprise a container (10A, 10B, 10C) having a child-safe type locking mechanism for releasably locking a lid (20A) on to the container (10A, 10B, 10C) so that the lid (20A, 20B, 20C) covers an opening of the container (10A, 10B, 10C).

The locking assembly includes shaped portions disposed on the lid (20A, 20B, 20C) and on the container (10A, 10B, 10C) that are configured to allow slidable engagement of the lid (20A, 20B, 20C) relative to the container (10A, 106, 10C) along a movement axis (X) between a first configuration (as shown in FIG. 1A) in which the lid covers the opening in to a second configuration (as shown in FIG. 1B) in which the lid does not cover the opening;

In this embodiment the container is substantially rectangular-shaped and includes side walls (10B, 10C). Shaped portions in the form of a pair of parallel rails (10D, 10E) are disposed along a rim of the container opening on the side walls (10B, 10C) of the container (10A, 10B, 10C). Shaped portions in the form of rail engagement elements (20B, 20C) are also disposed on the lid (20A, 20B, 20C) and are configured for slidable engagement with the parallel rails (10D, 10E).

The lid (20A, 20B, 20C) includes a main body (20A) comprises a substantially flat rectangular portion (20A) that is configured for covering the opening of the container. and side portions (20B, 20C) that extend substantially perpendicularly from elongate side-edges of the main body (20A).

The locking assembly comprises locking nubs (10B′, 10C′) protruding outwardly from each of the side-walls (10B, 10C) of the container along an axis (Y) which is transverse to the movement axis (X), and, locking nub receiving portions in the form of slots (20B′. 20C′) that are cut out of each of the side portions (20B, 20C) of the lid. The slots (20B′. 20C′) are shaped and dimensioned for snugly receiving their corresponding locking nubs. When the lid (20A, 20B, 20C) and container (10A, 10B, 10C) are slidably engaged together in the first configuration, the locking nubs (10B′, 10C′) disposed on the container (10A, 10B, 10C) are received within the corresponding slots (20B′. 20C′) disposed on the lid (20A, 20B, 20C) so as to restrict sliding movement of the lid (20A, 20B, 20C) relative to the container along the movement axis (X) from the first configuration in to the second configuration. The wall of the container (which in this embodiment is made from tin or aluminium) is configured to be inwardly depressible by a user so as to cause movement of the locking nubs (10B′, 10C)′ outwardly of the slots (20B′. 20C′) whereby the lid (20A, 20B, 20C) is then able to be slidably moved relative to the container (10A, 10B, 10C) along the movement axis (X) from the first configuration in to the second configuration.

In certain embodiments, the locking nubs may be disposed on the lid whilst the locking nub receiving portions may be disposed on the container in reverse fashion.

In yet further embodiments, the container may include a humidity control material. For instance such a material may be disposed on the lid of the container so as to face inwardly of the container when the lid covers the container and to control or regulate humidity within the container during use.

It would be appreciated that embodiments of the present invention as described herein require a degree of cognitive and dexterity ability to open the container which is designed to exceed the ability of young children. Further, such a solution provides added variability to its use that extends in contrast to existing methodologies for effecting child-safe locking mechanisms. Yet further, the streamlined design and relatively simplified function allows it to be applied to a wide variety of container, jars and bottles in numerous materials and sizes. Yet further, embodiments of the present invention are advantageous in that the combined lid/locking collar assembly may be pressed down in to secured engagement with the container when the combined lid/locking collar assembly is arranged in any position of coaxial rotation relative to the container thus making it easier to operate and saving time for the user.
