Description

Regulation 3.2 Revised 2/98 AUSTRALIA Patents Act, 1990 ORIGINAL COMPLETE SPECIFICATION TO BE COMPLETED BY THE APPLICANT NAME OF APPLICANT: DIMELLA, Vincent ACTUAL INVENTOR: DIMELLA, Vincent ADDRESS FOR SERVICE: Peter Maxwell and Associates Level 6 60 Pitt Street SYDNEY NSW 2000 INVENTION TITLE: PROCESS FOR MANUFACTURING A FLEX GRIP CUP-LIKE COASTER APPARATUS DETAILS OF ASSOCIATED APPLICATION NO(S): Divisional of Australian Patent Application No. 2003 228 437 filed on 4 April 2003 The following statement is a full description of this invention including the best method of performing it known to me: m:\docs\20031278\208470.doc PROCESS FOR MANUFACTURING A FLEX GRIP CUP-LIKE COASTER APPARATUS BACKGROUND OF THE INVENTION 5 The present invention relates generally to an improved process to create a means for preventing dripping from outer surfaces of vessels designed to house liquids, onto other surfaces. More specifically, the present invention relates to a process for making a novel enhanced io apparatus, working as a system for precluding undesired leakage, dripping, or the like liquid transmissions from the external surfaces of articles, including vessels (on to areas which are not intended to be wetted preventing damages thereto), particularly those used to house, transport and enable potable liquids to be consumed. 15 Commercial success has yet to be achieved for use of a unitary absorptive strip means issuing and placed over a lower section of desired cup, in spite of the long history of failed attempts. Likewise, the instant teachings mitigate or completely control the unaddressed problem of condensate and the like dripping from drinking vessel onto users. Done in 20 a user friendly and environmentally beneficial way, the elegant simplicity of the instant teachings speak for themselves, in combination with providing a unique mode for displaying a logo or symbol by economically efficient means. Attention is called to the following United States Letters Patents 25 and foreign publications, each of which has been examined and found to be inventively different than the instant teachings: 5,425,497; 5,645,196; NL 6611523; DT 1429226; 5,273,182; FR 1377535; 5,065,589; 4,681,239; 4,540,611; 30 3,103,295; 5,925,466; 5,693,714; 2 5,415,499; 4,948,443; 4,756,337; 2,617,549; 2,731,056; 2,570,954; 2,568,623; and 1,683,205. 5 An exemplary United States Letters Patent is No. 5,425,497 (the '497 patent) which issued for the JAVA JACKET®, an insulating sleeve for hot beverage containers that shields a user's hands from the same. Simply made from pressed and pleated paper products with two slitted attachment means disposed on the ends, this product encircles coffee 10 cups. The '497 patent is important because, as in at least half of the art reviewed in conjunction with the instant filing, it relates to insulating means that circle cups. It shows that invention is still available even within the narrowed and highly patented field of art defined by the is instant teachings. In contradistinction to the instant subject matter, however, the materials are not shown to include open-celled and otherwise plastic or rubber based compounds, in addition to the paper used with the present invention. At least two separate issues relating to the containment of liquids 20 in vessels are addressed by the teachings of this invention. The first problem is that of spillage. It is well known that a liquid in a nearly full open vessel can spill over the edges if the vessel is placed in certain positions. This is so because a liquid contained in a vessel will assume the shape of the vessel except for the upper surface of the liquid, which 25 will assume the form of a plane parallel to the plane of the surface of the earth. Thus, if the vessel is oriented or tipped in such a manner that it does not completely enclose the aforesaid upper surface of the liquid, the liquid will spill out of the vessel. Such tipping can occur in an instant of 3 time, so that spillage is a common problem particularly in the use of drinking vessels such as cups, beakers, glasses and the like. The second problem experienced by users of vessels containing liquids is the problem of condensation, or dew formation. As used in this s discussion, the term dew includes any kind of condensation of water on a surface. Dew is a thin film of water that has condensed on surface of objects, formed based on temperature gradients. The term condensation refers to a change from the gaseous state of a substance to the liquid state. In the present case, the condensation occurs because the capacity to of air to hold water vapor decreases as the air is cooled. The temperature at which condensation begins, for a sample of air with a given water vapor content, is termed the dew point. In general, rooms in which many people are present will have a relatively high dew point because of the high content of water vapor in exhaled breath. Likewise, outdoors on a warm 15 day on which cold drinks are particularly desirable, the dew point will be relatively high. From this brief discussion it will be clear that both the problems of spillage and dew formation as discussed above can be ameliorated in related ways. Small amounts of liquid that are spilled over the rim of a vessel, and small amounts of dew can be absorbed by a 20 suitable medium. This absorption occurs by several physical processes, including capillary action and adsorption. These processes can be explained by considering the effects of two opposing forces: adhesion, the attractive force between the molecules of fluid and the material, and cohesion, the attractive force between the molecules of the fluid. Thus, 25 provision of a suitable structure and medium for absorbing spillage and dew is one mechanism underlying the teachings of this invention. In addition, on the basis of the mechanism of dew formation on the surface of a vessel containing a differentially heated liquid described above, dew formation can be inhibited by insulation means for decreasing 4 the transfer of heat to the vessel surface from the layer of overlying air in contact with that surface. What has been discovered is that in combining a flexible grip, the right materials and a reusable and environmentally friendly molded, 5 injected, sprayed, layered or painted coating an ultimately consumer friendly apparatus, having memory, absorbency and low cost can be offered for consideration. The FLEX GRIP MIMPIT brand of coaster (which is defined for the purposes of the instant specification to include all of those aspects of the instant apparatus as defined in the claims which i are appended hereto, and those aspects of the process of making and using that are set forth) allow a user to remain free from the spillage and artifacts of the same that those who attend business meals in light colored clothing have come to dread, it also provides a marginally priced item that can be used to sport a logo for those who wish each user or consumer 15 having a drink to have a proximately located visual reminder. In short, despite the numerous attempts to innovate within this area, as shown by the many patents asserted to be related to these ideas, a longstanding need to protect both precious surfaces and users' clothing from the ravages of dripping liquids remains ineffectively addressed prior 20 to the advent of the instant teachings. Conventional napkins are a major cost of waste, ineffectively utilized and only marginally effective, likewise known 'coasters' fall apart, stick to the bottoms of glassware selectively (and then fall making embarrassing marks) or simply do not absorb. 25 SUMMARY AND OBJECTIVES OF THE PRESENT INVENTION A process is taught for making a selectively absorbent apparatus that is attached to another device and absorbs undesired liquid. According to a particularly preferred embodiment, the other device is a 5 drinking vessel and the teachings of the present invention comprise a flexible assembly form fitted to the bottom of the vessel, which stops condensation from, for example, drinking glasses from dripping onto any undesired surface, including liquid and oil sensitive surfaces and the 5 clothing of a user. The apparatus of the invention is advantageously constructed of paper, neoprene or foamed plastic, wherein said foamed plastic is a synthetic resin converted into a flexible sponge-like mass with an open cell structure. Under known appropriate conditions, certain thermosetting io or thermoplastic resin can be converted into a flexible sponge-like foam. Such plastics include, vinyls, polyethylene, silicones, cellulose acetate, and urethanes. Appropriate conditions for producing open cell plastics comprise incorporating an inert gas into the resin under pressure and then releasing the mixture to atmospheric pressure, followed by curing the 15 resultant foam. Alternatively, the apparatus of the invention may be made of foam rubber, also called sponge rubber or latex foam, wherein said foam rubber is a flexible, porous substance made from a natural or synthetic latex compounded with various well known ingredients and whipped into a 20 foam. The resulting product contains roughly about 85 percent air and 15 percent rubber and can be molded and vulcanized. Alternatively, the apparatus of the invention may be made of a member selected from the group known as sanitary papers or sanitary grades, whereby a disposable product is produced. Sanitary papers 25 include paper toweling of various thicknesses and are made from various proportions of sulfite and bleached kraft pulps with relatively little refining of the stock to preserve a soft, bulky absorbent sheet, folded, crimped layers, creped or otherwise treated. Because of the bulky texture of sanitary papers, the paper is advantageously treated with resins to 6 provide an embodiment of the invention with a smooth, printable outer surface having a highly absorbent core and good thermal insulating properties. Briefly stated, the process makes low-profile coaster type of s articles including any and all beverage containers to mitigate and/or preclude undesired transmission of liquids by selectively absorbing the same in an open celled medium bordered by a waterproofed layer. In a particularly preferred embodiment dimensional sizing is featured to lockingly or matingly engage, and completely cover a bottom portion and io selected side portions of at least about three standardly radiused sizes, for example a pint glass, soft drink or adult beverage container and a conventional beer bottle. Likewise, environmentally-friendly aspects include use of recyclables, saving on wasted paper, and -use for example, of old wetsuit material to make an industrially and economically efficient is means for preventing drippage, condensate and the like liquid based insults to clothes and surface materials. According to one embodiment, the process makes available at a low cost a device to mitigate dripping from a vessel made up of a single strip of elastic deformable absorbing material shaped as a low profile 20 round cup where the cup has inner and out surfaces defining a substantially flat bottom portion having sides extending from it and being elastically deformable to snugly engage the contours of the vessel. Likewise, the process for the manufacture of flexible coaster-like cupping apparatus comprises providing a blank of absorbent material, 25 creating a plurality of unitary rectangular strips having first and second ends and a round shaped sub-unit separated from the blank, bonding the first and second ends in abuting relationship disposed about the round shaped sub-unit to form a cup shaped article.

7 Similarly, a process for mitigating damage from spilling and/or dripping while displaying an image comprises the steps of providing an elastically deformable cup-shaped coaster attachment having a low profile and size to conform, at an expanded position, with at least about one of 5 three sizes of standardly radiused vessel bottoms, by emplacing the chosen cup-shaped coaster attachment on an appropriately sized bottom wehrerby a visual surface is provided about the peripheral portion of the vessel by the outer surface of the vessel. Finally, the process makes an article of manufacture defined as a io low profile cup shaped coaster means for deformably conforming to the contours of a vessel made up of at least a layer of material where the means stretches from a first unconformed position to a second conformed position when placed on the bottom of the vessel and the means further comprises inner and outer surfaces defining a substantially flat bottom 15 portion connected to side walls which extend therefrom and whereby the vessel is maintained in substantially orthogonal relationship to a planar surface upon which it rests, when the articles in is the secondf conformed position of the bottom of the vessel. The above described and many other features and attendant 20 advantages of the present invention will become apparent by reference to the following detailed description when considered in conjunction with the accompanying drawings, in which related reference designators bare common, or identical numbers. 25 BRIEF DESCRIPTION OF THE DRAWINGS Detailed descriptions of preferred embodiments of the invention will be made with reference to the accompanying drawings, in which like reference designators represent common elements, mindful that multiple 8 alternate embodiments of the present invention are both illustrated and contemplated. FIG. 1 is a schematic of partial perspective view of a generalized conception of one embodiment of the device, according to the teachings 5 of the present invention; FIG. 2 is an embodiment used with a conventional pint glass and an additional view of the instant teachings as shown in one embodiment of the device, according to the teachings of the present invention; FIG. 3 is an embodiment used with a conventional coffee cup and io an additional view of the instant teachings as shown in one embodiment of the device, according to the teachings of the present invention; FIG. 4 is a view of an alternate embodiment of the apparatus shown in FIG. 1; FIG. 5A is a schematic view of an embodiment used with a is conventional wine bottle; Fig. 5B is a view of the instant teachings as shown in one embodiment of the device, according to the teachings of the present invention; FIG. 7A shows an embodiment used with a conventional beer 20 bottle; FIG. 7B shows a view of the instant teachings as shown in an embodiment of the device, according to the teachings of the present invention; FIG. 8 is another alternate embodiment crafted from a used piece 25 of neoprene, effective for use with any conventional wine glass; FIG. 9 is yet another alternate preferred embodiment wherein a substantially translucent material and a logo display zone complement the teachings of the present invention; 9 FIG. 10 - 13 show currently prototyped devices made up of neoprene (Fig. 10-12) and paper (Fig. 13) which embody the instant teachings. 5 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present inventor has discovered that he can BOTH prevent unwanted liquids from damaging the top surfaces of, for example, tables, desks (and any other desired substrate) and stop dripping onto clothing of io the user drinking from or pouring from a vessel. Since there is clearly a longstanding need to solve the problems associated with each of these issues, the instant subject matter merits consideration in virtue of its inherent novelty, inventive step and the non-obvious nature of its teachings. is The instant specification is a detailed description of the best presently known mode of carrying out the invention. This description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention. The section titles and overall organization of the present detailed description are for the purpose 20 of convenience only and are not intended to limit the present invention. Likewise, although the instant teachings have proven to be effective with currently available materials, it is contemplated that newly discovered compounds and constituents having the properties claimed herein are readily exchangeable by a person having reasonable skill in the art. 25 The physics of water creates untoward challenges which impinge upon many of the conveniences that have been developed in modern society. Following myriads of testing situations, the present inventor has discovered that he can prevent most condensation aliquots from being driven by gravity onto a user's clothes and any number of given surfaces 10 functioning as 'tables'. This is crucially important given the possible damage to surfaces which are not designed to receive water, such as certain finished or unfinished woods, types of high-end tiles, and further includes all of those articles objects, papers and the like which may be 5 damaged or destroyed through contact with liquids at all. Since condensation of liquid occurs whenever either gas changes to liquid, or when water-based (compounds, mixtures, admixtures, combinations, drinks, potions) liquids are formed directly by catabolic or anabolic changes - a serious issues arises with glassine and plastic io drinking vessels. This is because these reactions are temperature driven, and most users prefer to have their drinks decanted into vessels at temperatures different then the vessels themselves, or there are other protocol-based or aesthetic-based reasons, in addition to the individuated and personalized or subjective bases involved. 15 Each time that someone is served from a container of liquid stored or designed to be stored at a temperature different from the vessel, there is the potential for the generation and gravity-based travel of condensate. Likewise, when a glass, for example, is placed on a surface by a human, unless perfect placement is achieved, minor amounts of the liquid are 20 spilled, and offensive noise (for example the 'clanking' of glasses). Each of these problems is both addressed and ameliorated by the advent of the instant teachings. Similarly, the inherent stability provided by a cushioned means for matingly engaging the bottom of a glass in and of itself mitigates the 25 volume of aliquots which escape 'over the top' of drinking vessels. By being both price efficient, washable and recyclable, the present invention necessarily has a positive impact on environmental concerns and issues by precluding the wasting of other materials, as discussed below.

11 FIG. I shows a schematized article, in this case a vessel for housing liquids at 2. Vessel 2 is generally glassine, plastic based, or crafted from a marginally pliable or stiffened material (as defined by its respective Young's Modulus) such that it can support the weight of a 5 volume of liquid disposed therein. The present invention likewise works well to stabilize and prevent dripping from 'waxed cardboard' and/or styrene disposable cups which abound in the fast-food industry, as a promotional item. Bottom surface 10, of vessel 2 is completely covered by FLEX@ 10 GRIP apparatus 4, whereby inner surface 8, abuts bottom surface 10. Inner wall 12 fittingly embraces the outer surface of vessel 2's bottom region, whereby transmission of liquid therethrough is precluded, or substantially mitigated and stability is maintained by keeping the angle susbstantially orthogonal. See Fig. 3. is FLEX GRIP MIMPI T M apparatus 4 is composed of any number of flexible materials, including neoprene (available as shown in Fig. 9, and Fig.s' 10 -13 from the KOLDER Corporation, Edinburgh, Texas, USA), sponge foam, conventional plastics, known rubbers, PTFE compounds made from any of the same, urethanes, polysiloxanes, and the like 20 synthetics and the like unknown materials which share the characteristic of having an open-celled aspect, and a waterproofed aspect (imperviousness to liquids). Facultative fin or stabilizer 6 provide the ability to stand on a substantially level surface, and is optional within the context of the instant 25 teachings. However, it may be extended, textured, shortened, stiffened or otherwise customized for enhanced stability, for example when travel is within the car of a train, a boat or an airplane, or any other surface wherein a substantially planar surface is subject to vertical or transverse forces.

12 Referring now to FIG. 2, the article/workpiece/vessel 2 is a conventional pint glass, such as used to hold any number of drinks from beer to water. FLEX GRIP MIMPI T M apparatus 22 is shown in an attached posture relative to vessel 2, whereby FLEX GRIP MIMP T M 5 apparatus 22 matingly engages a bottom portion of vessel 2, and remains attached to the same when vessel 2 is lifted (for example, by a user to take a drink). Likewise, when vessel 2, bracingly engaged to FLEX GRIP apparatus 22 is replaced on a substantially planar surface (as indicated by ordinate y) the entire assembly is maintained in a substantially 10 orthogonal angle theta 13, relative to the substantially planar surface. The instant apparatus 22 may be a unitary neoprene construction neoprene (available from the KOLDER Corporation, Edinburgh, Texas, USA), may be EVA, or any number of related plastic or rubberized petroleum distillate products. Similarly, depending on the porosity of the 15 material, those skilled in the art may substitute inherently similar materials. Likewise, the instant apparatus 22 may be composed of a plurality of strips of mill ends, remnants, or 'scraps' of, for example, neoprene, with or without an outer coating layer that is waterproofed. Conventional (from at least about .83 mm to about 5.5 mm) wetsuit material has been used, 20 with the outermost waterproofed coating layer, and comprises a preferred embodiment of the instant teachings. The present inventor has discovered that salvage value of 'used' wetsuits may be enhanced by parsing the same and rejoining at least two, or as many as several pieces, using standardized cementing material 25 (BLOCK/SURF of Chatsworth, CA). FLEX GRIP apparatus 22 in this way serves at least three important functions for the preservation of the environment. First, it prevents waste of natural resources by recycling used articles having appropriate plastic or rubber characteristics (including wetsuits, tires, 13 etc...) and second it prevents the needless waste of paper-based supplies like napkins, paper towels, cardboard coasters, and third it obviates the need for dry-cleaning which saves precious resources and likewise stops the dumping of noxious chemicals into drains and thus into the water 5 table. Rubbers, plastics and the like materials may be sprayed on, melted, cured, baked, laser trimmed and otherwise subject to manipulations based upon desired porosity and 'hand'. Owing to the memory of such materials, minimization of the size and shape of FLEX 10 GRIP apparatus 22 is further contemplated based upon the particular application as issue. By way of further example, FLEX GRIP apparatus 22 is further composed of translucent or transparent open-celled material and has been crafted with an extremely low profile for use with wine glasses, 15 snifters for brandy and the like stem-using vessels. Likewise, surface characteristics according to the instant teachings are malleable and may be tailored to be hardened, clear, subject to logos being disposed therein, mounted thereupon, embossed, engraved, electronically displayed and the like. 20 Referring now to FIG.'s 3 - 9 it will be appreciated how the dimensional variation encompassed by the instant teachings allows the present invention to be varied to fit all known beverage containers. FIG. 3 and 8-9 each shows pre-formed cupping means 22, housing a conventional coffee cup 2. It is noted that according to this 25 embodiment, pre-formed cupping means 22, further comprises peripheral/outer layer 38. As discussed above and described below, the nature of the materials as absorbent functions in complementary fashion with the waterproofed nature of at least on aspect of the same.

14 For example, according to an embodiment with outer layer 38, the surface may be a smoothed and sheened rubberized coating, over principal body 22 of neoprene neoprene (available as shown in Fig. 9, and Fig.s' 10 -13 from the KOLDER Corporation, Edinburgh, Texas, USA). s As discussed, for example, since the salvage value of 'used' wetsuits may be enhanced by parsing the same and rejoining at least two, or as many as several pieces, using standardized cementing material (BLOCK/SURF of Chatsworth, CA), FIG. 3 can include either originally reclaimed wetsuit material (at any known thickness, for example, 5 mm in this model) or the io same enhanced by melting, gluing, embossing or adhesion of other surface modalities, elements, pieces, finishing or adhesions. Since outer layer 38 is waterproofed, when condensation forms on vessel 2, it is pulled downward by gravity until lodged in absorbent layer(s) 22 and then held in by outer layer 38. Those having a modicum of skill 15 will readily apply the instant teachings to bottles, cans, wine glasses, pint glasses, alternately shaped vessels, plastic cups, child-proof cups, pitchers and the like. Likewise it is known that those of skill can understand readily the remaining figures and further understand the many and varied industrial, 20 chemical, laboratory based usages of the instant teachings. For example, incorporation of a neutralizing agent, or the like chemical equilibration means in the open-celled portion when dealing with acids or the like specialty chemicals. Similarly, incorporation of additional elements, such as a girth, or 25 cinching means for tightening around the desired diameter is incorporated within the instant teachings. Such devices allow for on-site custom fitting or variations of the 'one-side fits all' versions of the present invention and are clearly contemplated by the scope of the instant teachings.

15 Referring now specifically only to Fig. 8 and FIG.9, there are shown two particularly preferred embodiments, substantially flexible jacket 22 having at least an inner surface and an outer surface, wherein said jacket is adapted to fittingly cover and cuppingly engage an area 5 comprising substantially the entire bottom and a predetermined portion of the lower sides of a vessel for containing a liquid below ambient temperature, wherein said jacket is constructed of material that impedes heat transfer from said outer surface to said liquid, and wherein said jacket is capable of absorbing said liquid. 10 Those having a modicum of skill in the art understand that thIs can be either a plastic based or paper based assembly, and the present invention likewise includes a kit for sales, comprising substantially flexible jacket 22 having at least an inner surface and an outer surface, packaging materials and, at least one instructional device for explaining 15 the use of said device. For example, used pieces or recycled pieces of wetsuits and recycled paper products can be offered for users to assemble their own FLEX@ GRIP mimpi apparatus. Likewise, in FIG. 9 a translucent or transparent version 22 is shown having an embossed, tattooed, engraved, stickered, pressed, melted, 20 scored or otherwise emplaced logo ["MIMPITM"] disposed whererby a users can view the same. Although the present invention has been described in terms of the preferred embodiments above, numerous modifications and/or additions to the above-described preferred embodiments would be 25 readily apparent to one skilled in the art. It is intended that the scope of the present invention extends to all such modifications and/or additions and that the scope of the present invention is limited solely by the claims set forth below.
