Description

MULTIPLE PIECE HANDLE FOR DISPOSABLE RAZOR
The present invention is directed to a multiple piece handle for disposable razors and a method for the manufacture of the handle of a wet razor, and in particular, the handle of a disposable wet razor.
BACKGROUND OF THE INVENTION
Disposable wet razors are known in the art. For many years, complete disposable wet razors have been articles mass produced at reasonable costs and have provided a suitable and sufficient shave. Generally, disposable wet razors consist of a handle with a gripping part and a receiving part for receiving a razor blade or a razor blade unit. Disposable razors are distinguished from conventional wet razors in that in disposable razors the handle region is an integral component of the whole razor, whereas non-disposable razors are often constructed of separate components. The individual elements comprising the wet non-disposable razor systems permit the use of technological developments of the separate components which is not possible by integral disposable systems.
It is known in the art that the comfort and quality of a shave is influenced by a series of different elements of the razor system of which the gripping region is one such important element. The arrangement of the gripping region is therefore a constant optimization of a large number of possible factors of improved handling, improved grip and improved balance. In addition, different forms and completely different shapes and technological quality of the gripping region can be made. For example, pre-surgical area disposable razors may be arranged completely differently than barber razors or complete disposable razors for wet shaving. Disposable wet razors are mass produced articles, whereby the smallest economical influence has to be taken into consideration, and, as such, the desired varied requirements can not always be fulfilled.
Known handles of wet razors, in particular disposable wet razors, are conventionally provided by an entirely plastic formed part or a plastic part with a longitudinally formed core. One successful embodiment of an open-and- closed handle design contains a double S-shaped section. This particular shape provides a design which ensures proper handling for the user during shaving. It can easily be demonstrated that any change of the shape will lead to more open areas which will reduce the handling substantially. Nevertheless, the double S-shaped design is material extensive because it represents the surface equivalent of five side elements and, because of the very tight material organization, the cooling ability of the molding tool during manufacture is limited so that the molding cycle time will not be below 7-8 seconds.
A second technical improvement for disposable handle design and manufacture is based on a design with a longitudinal core. This solution avoids the disadvantage of the five side elements of the previous embodiment, but requires greater wall thicknesses for stability which need a longer cooling time in the molding tool before the disposable handle may be injected. Consequently, there is no material saving (due to greater wall thicknesses for stability) and a fairly long cycle time of about ten seconds (due to the longer cooling time and the time needed to remove the core) . It is also obvious that tool designs with a core are more expensive and allow fewer cavities per tool for any given molding machine size. On the basis of this production method the possibilities of variation with regard to the arrangement of the shape from the standpoint of economical manufacture, i.e. with minimum material content and minimal production costs, are severely limited. In addition, there are practically no additional inserted variable elements which would improve characteristics such as balancing, gripping, or the like. Finally, the assembly method has an influence on the conventional methods of production of handles in which a razor blade unit must be arranged on to the blade.
Summary of the Invention
The present invention is directed to a multiple piece disposable razor handle and a method of the manufacture of such a handle of a wet razor. In particular, the invention is directed to a disposable wet razor which is improved such that, in consideration of the low material requirement and low production costs of high volume production, the possibilities of variation with regard to the grip arrangement and consideration of the different technological requirements are ensured.
As the technical solution to the object of the present invention, a method for the production of the handle of a wet razor, in particular a wet disposable razor is proposed, whereby at least two shaped elements, with each element manufactured separately and having connecting regions complementary to each other, are utilized to form the handle when they are positioned together and connected to each other.
According to the present invention, the disposable wet shave razor handle is made by a modular system in which the desired individual elements are variable. Separate elements or shaped elements with different surfaces or special additional elements can be provided. By means of the positioning together of the shaped elements the blade assembly can be considerably simplified and also adjustment to be such so that the handle fits a new razor blade system. In addition, special requirements for particular insert areas can be considered with ease.
It is proposed that the shaped elements of the handle are advantageously thin walled, shell shaped elements. It is particularly advantageous for the shaped elements to be made from plastic parts. According to a further proposal of the invention there may be two elements which form the handle when positioned together are create a separation plane which is flat and lies along the longitudinal middle axis of the handle. According to a preferred embodiment of the invention, two mirror symmetrical shell formed elements are provided.
Moldflow analysis and finite element evaluation have demonstrated that a technically proper designed thin walled shall shaped element will provide a higher stability and can be manufactured on molding machines in less then six seconds, with this design, the two halves of the molding tool used to form the open shells can be cooled quicker and more efficiently, thereby leading to a dramatic reduction in the mold cycle time. Depending on a specific design of a thin walled disposable handle element, it is possible to achieve a cooling time of less then two seconds with an overall process time of less than five seconds. Ribs can be added to provide sufficiently even if the wall thicknesses are below 1 mm. The filling of the mold tool is faster since insert pressure can be higher and the flow of plastic material into the mold is not interrupted by many design and shape intersections. The simpler parts, which ultimately will provide a more complex and user friendly disposable handle design, need less complex and sophisticated molding tools. In a given molding machine more cavities can be incorporated. The present invention therefor insures less material for a required surface size, shorter cycle time due to better tool cooling and filling, more cavities per given machine size and less investment due to simpler tools. The assembly of the two shells will be performed on the assembly machine with positive impact on the machine speed because the open shell elements provide better orientation features for bowl feeding. It is also obvious that the two or more shell design provides a variety of new methods to attach the handle to the blade unit.
In a preferred embodiment, additional elements can be placed in or on the separate shaped elements. One such embodiment of the invention provides a weight element is provided. Still further, strengthening lugs can be provided in the shaped elements.
The connection of the shaped elements according to the invention can be provided by any form of adhesive. Welding or any particular connection technology, including simple grip connections, can also be used. The connection advantageously occurs during the assembly of the razor.
By means of the inventive method, it is possible to vary the handle of various disposable wet razors. The handle of the invention is of modular construction and the separate modules can be varied according to the requirements of the particular razor or the state of the technological developments.
Further, disposable razor handles of the present invention may be economically constructed from combinations of different materials, for example from rubber with plastic or metal elements with plastic. Likewise the same material on different colors can be combined and thereby the aesthetic performance considerably improved. Finally the invention protects a handle of a wet razor, in particular or a disposable wet razor which is characterized in that it is produced by the described process that it comprises at least two shaped elements with two connecting regions complementary to each other.
