DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to containers or pails, and more particularly to containers or pails having a handle integral thereto. The present invention also relates to a tamper-evident and leak-proof container and lid combination.
BACKGROUND OF THE INVENTION
It is well-known to provide containers or pails with a handle for ease of handling and transportation. Similarly, containers made of plastic material, such as polyethylene, are common in the industry because of their strength and light weight compared to containers made of other materials. The handles on these plastic containers generally comprise a suitably configured metal rod or plastic rod disposed at diametrically opposite points near the container's top. The handle is usually pivotally connected to the container to allow it to swing from one side of the container to the other.
The usual way to pivotally connect the handle to the container is by providing a raised element on the outside of the container. On this raised area is a hole through which the ends of the handle are inserted and hooked in place. The ends of the handle are adapted to allow the handle to swing from one side to the other.
The disadvantages of the containers and handles of the prior art are that these two components are manufactured separately. Thus, additional work is required to connect the handle in place on the container. Secondly, it is usual for writing or other printed matter to be printed on the outside of the container. The additional step of connecting the handle to the container cannot usually be done until the printing is completed.
Tamper-evident containers have been described in the art. For example, Canadian Patent No. 2,019,225 issued to IPL Inc. describes a square tamper-evident closure and container combination incorporating means to provide a visual indication of the removal of the closure. The means is a flange peripherally extending from the container having weakened corners such that the flange will break when the closure is removed.
Leak-proof containers and closures are also known in the art. U.S. Pat. No. 4,037,748 issued to Stubbs describes a plastic leak-proof container, but requires the formation of a curl on the rim of the container which is used with a suitable lid to make the container leak-proof.
SUMMARY OF THE INVENTION
According to the present invention, a container is provided in which the handle is integral to the container itself, rather than being manufactured separately and then connected thereto. The portions of the handle near the container are bendable to allow the handle to swing from one side to the other of the container. One or more breakable connections are preferably provided between a central portion of the carrying handle and the container wall for holding the handle in position. Among other advantages, this feature facilitates the process of printing on the container wall. In accordance with a further embodiment of the present invention a tamper-evident and leak-proof container and lid combination is provided.
