Body washer and exfoliator

Abstract: A body washer and exfoliator (14) has at least two tubular nets (16, 18, 20) that are formed of distortable plastic material and that are located one inside the other and gathered together at-a point so as to form, by the application of heat at and around that point, a sinuous ball like structure.

Description: The present invention relates to a body washer and exfoliator, being of particular use to persons having a shower or bath. Body washers and exfoliators come in many different shapes and sizes. Among these are the commonly used brushes, straps, sponges, loofahs and rock scrubbers. More recently, netting has been used to form a washer of a sinuous ball like structure. However, net washers of this structure are easily disrupted by the rubbing and washing action and, over time, lose their shape and strength. Furthermore, these net washers are not sufficiently rigid for tough skin that may require vigorous scrubbing, such as on the upper back of a male person, to achieve an effective exfoliating action. It is an object of the present invention to overcome or substantially ameliorate the shortcomings and disadvantages of the prior art. According to the invention, there is provided a body washer and exfoliator comprising at least two tubular nets that are formed of distortable plastic material and that are located one inside the other and gathered together at a point so as to form, by the application of heat at and around that point, a sinuous ball like structure. Preferably, the number of tubular nets equals three, and the tubular nets are formed by extrusion. In order that the invention may be readily understood and put into practical effect, reference will be made to the accompanying drawings, in which: Fig 1. shows a single tubular net, and a body washer of the prior art produced therefrom, Fig 2. shows three tubular nets, and a preferred body washer and exfoliator of the present invention produced therefrom, Fig 3. is a perspective view of the three tubular nets shown in Fig 2 being inserted one within the other to produce a concentric arrangement in accordance with a step in the process for producing the body washer and exfoliator of Fig 2, Fig 4. is a front elevational view of a frame and a portion of a concentric arrangement of the three tubular nets shown in Fig 3 being stretched and fitted onto the frame in accordance with another step in the process for producing the body washer and exfoliator of Fig 2, Fig 5. is a view similar to that of Fig 4, but in which the stretched and fitted concentric arrangement of nets is being gathered together in accordance with yet another step in the process for producing the body washer and exfoliator of Fig 2, Fig 6. is a view similar to that of Fig 5, but in which the gathered concentric arrangement of nets is having hot air applied to the centre of the "gather" in accordance with a further step in the process for producing the body washer and exfoliator of Fig 2, and Fig 7. is a view similar to that of Fig 6, but in which the hot air treated "gather" is being tied tightly around its centre by a tie means so as to provide a constricted neck portion in accordance with a still further step in the process for producing the body washer and exfoliator of Fig 2. The prior art body washer 10 shown in Fig 1 is made from a single net 12 of a soft polymer based material which has been formed into a sinuous ball like tertiary structure. As a result, the body washer 10 may be crumpled easily by application of hand pressure to its tertiary structure, so forming a distorted, irregular tertiary structure that may be ineffective for certain circumstances of use by persons having a shower or bath, as described in the earlier discussion of the prior art. An approach to overcoming this problem has been to select a harder but less distortable material for making the single net. Another approach has been to make the body washer smaller in overall diameter for the same length of net by not applying any heat during the formation of the washer, and thereby avoiding release of the elasticity of the netting which would otherwise contribute to a larger and less dense tertiary structure, such as that possessed by the washer in Fig 1. The body washer and exfoliator 14 of Fig 2 has as large a diameter as the washer 10, but is denser and more rigid, without utilizing a net material that is any harder then that which may be used for the washer 10. The body washer and exfoliator 14 is, in this instance, produced from three tubular nets as also shown in Fig 2. The three tubular nets 16, 18, 20 are each of a different colour to suit market tastes and have an unstretched diameter of, say, 15 cm. They are separately extruded and cut to a desired length of, say, 1.5 metres (although this length may vary from 1 metre and upwards). Each net 16, 18 and 20 is made from 48% EVA polymer, 48% low density polymer, and 4% "super slip" additive. As shown in Fig 3, the three tubular nets 16, 18, 20 are then inserted one within the other to produce a concentric arrangement 22 of three equal length tubular nets. The concentric arrangement 22 is then stretched and fitted onto a metal frame 24 by pulling the arrangement 22 downwardly over the two opposed upright portions 26, 28 as shown in Fig 4. The shape and construction of the frame 24 may vary so as to suit the particular netting material that is used, and so as to facilitate the various steps in the process that utilize the frame 24. As shown in Fig 5, the concentric arrangement 22 is then gathered together over the metal frame 24 which may vary in width from about 22 cm to about 30 cm so as to provide for different sizes of net. As an alternative to the aforementioned, the metal frame 24 may be used both as a template for the step of inserting the nets 16, 18, 20 one within the other, and as aforementioned, for the purpose of gathering together the concentric arrangement. Whilst the concentric arrangement 22 is in a gathered state on the metal frame, hot air is applied to the centre of the "gather" 30, as shown in Fig 6, in order to release the elasticity of the netting at approximately 3 cm from either side of the centre of the "gather" 30. A synthetic string or other tie means 32 is tied tightly around the centre of the "gather" 30 to provide a constricted neck portion 34 and a means for attaching a hand grip cord 36 or the like thereto. The hand grip cord 36 may be used for holding the body washer and exfoliator 14 or for hanging it from a hook in the shower or bath. The heat treated and tied "gather" 30 is then drawn out from within the confinement of the metal frame 24 and its sinuous ball like structure, as shown by the body washer and exfoliator 14 in Fig 2, is allowed to form by unrestricted elastic expansion. Various modifications may be made in details of design and construction, as well as the process, without departing from the scope and ambit of the invention as defined by the appendent claims.

Claims: A body washer and exfoliator comprising at least two tubular nets that are formed of distortable plastic material and that are located one inside the other and gathered together at a point so as to form, by the application of heat at and around that point, a sinuous ball like structure. The body washer and exfoliator of claim 1 wherein the tubular nets are formed by extrusion. The body washer and exfoliator of claim 1 or claim 2 wherein the number of tubular nets equals three.
