DESCRIPTION:
BRIEF SUMMARY
This invention is concerned with razors and it relates in particular to a shaving system of a kind comprising a razor handle for detachably mounting a blade unit to enable replacement of the blade unit when its blade or blades have become dulled, and a supply of blade units carried in a dispensing container which holds the blade units until they are required for use and which facilitates completion of an operation to replace a blade unit on the handle without need for the person performing the operation having to touch directly either the used blade unit or the replacement blade unit. Shaving systems of this kind are known and the ability to change a blade unit on the handle without having to manipulate the blade units themselves with the fingers of the hand is of considerable advantage from a safety point of view.
It has been proposed to construct the dispensing container so that the blade units are stored side-by-side in a single row between entry and exit ends of the container. By "side-by-side" it is meant the blade units are parallel to each other with the cap of one blade unit adjacent the guard of the next blade unit. In these known dispensers means are provided on the container for guiding the handle along the container so that when the handle is inserted into and moved along the container, the blade unit mounted on the handle displaces the row of blade units forwardly to bring the leading blade unit of the row into a dispensing location, the handle releases the blade unit so that it becomes a trailing blade unit in the row, and the handle is guided past all the blade units except the leading blade unit to which it becomes connected so that the leading blade unit is withdrawn from the exit end of the container in operative engagement with the handle. Such an arrangement is disclosed in WO 90/11875, for example, and it has the attraction that a blade unit replacement operation is completed by a single stroke of the razor handle through the container. Also, it is ensured that used blade units are returned to the container for safe disposal. However, there are some drawbacks. As the container is required to guide the handle and control the latching mechanism by means of which it is connected to a blade unit, the container has a rather complicated form so that manufacturing costs are relatively high.
According to the present invention there is provided a shaving system comprising a razor handle for detachably mounting a blade unit, and a dispensing container housing a plurality of blade units side-by-side in a row between entry and exit ends of the container, the handle being arranged to be guided along the container during blade unit replacement for disengaging and leaving the blade unit initially thereon at the trailing end of the row and for engaging and withdrawing from the container the leading blade unit, wherein means for guiding the razor handle are provided on the blade units.
According to an embodiment of the invention there is provided a dispensing container for holding a row of blade units arranged to be moved in unison along the container to advance the leading blade to a dispensing position, and stop means are provided at the end of the container whereby the leading blade is constrained to be moved upwardly away from the bottom of the container for removal from the container.
The present invention also provides a novel safety razor structure which is particularly suited to the shaving system of the invention as defined above. Thus, there is provided a safety razor including a handle, and a blade unit detachably mounted on the handle by a releasable coupling comprising complementary sliding connection means arranged on the rear of the blade-unit and on the handle for connecting the handle to the blade unit and disconnecting the handle from the blade unit by movement relative thereto in a predetermined forward direction transverse to the length of the blade unit, and releasable latching means on the handle for engaging the blade unit to lock the blade unit to the handle to prevent sliding m
