Retainer for poultry hocks

Abstract

A device for retaining and trussing the hocks of poultry carcass in juxtaposition and proximal to the body during processing, packaging, shipping, storage, and / or cooking. The present invention, including hock retaining members, may be constructed of a unitary, plate-like member of resilient material and it includes two openings for fitting about and retaining the hocks, an anchor to be affixed to the poultry carcass, and a connecting means between the hock retaining members and the anchor. The connecting members provides a spring force to keep the hocks and thus the legs juxtaposed to the carcass and each other.

Description

BACKGROUND OF THE INVENTION [0001] 1. Technical Field [0002] The present invention relates generally to a device for trussing or retaining the hocks of poultry carcasses and more particularly to a retainer that can engage the hocks of a poultry carcass to retain the legs in juxtaposition during processing, packaging, shipping and possibly cooking. [0003] 2. Prior Art [0004] As is appreciated by those skilled in the art, the processing, packaging and shipping of poultry carcasses can be made easier by creating relative uniformity amongst trussed poultry carcasses. For example, if the hocks of poultry carcasses are protruding from the animal carcass, then the extending limbs can interfere with packaging machinery and tear the shrink-wrap. Trussing the hocks, thereby holding the legs together close to the body, can help to avoid this problem. Further, it is easier to cook a trussed poultry carcass, especially on a rotisserie, as the legs will be retained against the body and not flop a...

Benefits of technology

[0014] A first end of the present invention has a hock retaining portion that receives and retains the tops of the hocks and a second end has an anchor that may be inserted into the cavity of the carcass or in the tail section of the carcass. In addition, the hock retaining portion is preferably rotatable. In use, the hock retaining means are rotated approximately 180°, the hocks are placed in the hock retaining means, and the hock retaining means are released. The hock retaining means attempt to return (rotate back) to their original position, thus locking the hocks. The half moon notches fit over the hocks with end-points fitting within the hock dimples, and the central tab fits between the ankles, thus helping to secure the hocks.

[0015] The present invention may be constructed as a unitary, plate-like member of resilient material. The retainer can be mounted on the hocks by a single upward or downward motion of the retainer over the hocks. As the retainer is placed, or snapped, over the hock, the hock is caught in the retainer. Because the hock receiving openings are juxtaposed and the hocks of the poultry carcass are loaded into the hock receiving openings, the loading of the hocks into the retainer conveniently juxtaposes the hocks proximal to each other.

[0016] The relatively simple mechanism for loading the retainer with the hocks of the poultry carcass can allow for efficient mounting by hand or by automation. Poultry processing workers use an upward or downward motion to mount the retainer onto the hocks. Alternatively, as the retainer can have a generally plate-like configuration, which is an optimal shape to be fitted in an automated poultry-processing machine, the retainer can be incorporated efficiently into an automated process or operation. A tab may be located on the retainer which tab may include a hole for use in an automated machine for placing the retainer on the poultry carcass. The retainer also can have a slot for mounting onto a supply bar either for storing a number of the retainers or for feeding the retainers into an automated retainer-mounting machine. Further, as the present invention has a generally simple structure, the device can be manufactured relatively easily and inexpensively and can be mounted quickly and efficiently on the hocks.

Problems solved by technology

For example, if the hocks of poultry carcasses are protruding from the animal carcass, then the extending limbs can interfere with packaging machinery and tear the shrink-wrap.
