INVENTOR JOHN J. NAPPI ATTORNEYS TACIKY MAT STACK BACKGROUND AND SUMMARY OF THE INVENTION The present invention relates generally to a tacky mat stack adapted to remove accumulated dirt particles from the underside of shoes or other traffic during passage thereof across the mat. More particularly, it is directed to a new and improved tacky mat construction which facilitates the easy sequential removal of each uppermost mat sheet from the stack.
A tacky mat stack of the type involved in this invention has been described in detail in my earlier U.S. Pat. No. 3,083,393. Broadly, it consists of a plurality of superimposed coextensive sheets, each having a pressure-sensitive adhesive on the top surface thereof. As will be appreciated, the tightly woven fabric or cloth backing of each adhesive sheet necessarily exhibited sufficient strength to be stripped or peeled from the stack without tearing or rupturing. Accordingly, a tightly woven, strong and sturdy fabric has heretofore been used for this purpose.
Unfortunately, the constant passage of pedestrian traffic across a stack containing several adhesive sheets constantly forces the cloth backing of each sheet into intimate engage ment with the adhesive tread surface on the adjacent underlying sheet. This disadvantageously causes the adhesive to penetrate the cloth backing, resulting in the tight bonding or welding of the superimposed sheets to each other. This problem is particularly evident on the lowermost sheets of the stack and creates substantial difficulty in effecting the desired stripping or peeling of the soiled layers from the mat stack.
Accordingly, in my US. Pat. No. 3,501,797 there is described a stack construction incorporating a transversely extending pull string at one end of each sheet for effecting preliminary release of the end portion of the top sheet. As indicated in that patent the pull string is merely interposed between adjacent sheets and is not secured thereto. As the string is pulled from its rest position, it effects a sweeping motion to produce the desired initial releasing action. However, this construction does not reduce the tendency of the sheets to adhesively weld to one another. Additionally, the sheets of the mat stack are not provided with means for securely gripping the individual sheets themselves, and unless great care is taken to ensure the continued separation of the string-released sheet portion, it will readily reengage the underlying sheet and due to its tacky nature will immediately adhere thereto causing substantial difficulty in effecting the desired separation.
Attempts to insert conventional release layers, such as a layer of silicone treated paper or the like, between the tacky mat sheets of the stack in order to prevent the undesirable bonding or welding of these super-imposed sheets has proved unsatisfactory. Such release layers disadvantageously permit sliding and other movement of the sheets relative to each other, thereby creating a safety hazard for the user of the mat and unwanted adhesion of the top mat sheet to the pedestrian traffic using the mat.
Accordingly, it is a primary object of the present invention to provide a new and improved tacky mat stack of pressuresensitive adhesive coated sheets exhibiting ease of separation, coupled with relative immovability between the sheets of the stack during use.
Another object of the present invention is to provide a tacky mat stack of the type described wherein the adhesive sheets are composite laminar structures incorporating an adhesive barrier suited for releasable adherence to the underlying tread surface while preventing penetration therethrough by the adhesive, thereby preventing the disadvantageous welding of the sheets and facilitating rapid separation thereof despite the passage of heavy traffic loads over the mat stack.
Still another object of the present invention is to provide a tacky mat stack of the type described comprised of new and improved composite adhesive sheets incorporating materials that independently might not exhibit the requisite strength characteristics but when combined provide an extremely strong and durable structural relationship in a highly efficient and economical manner without disadvantageously increasing the thickness of the adhesive sheet structure.
A further object of the present invention is to provide a tacky mat stack of the type described having an improved easily grasped pull tab for effecting an adhesive-free area between the sheets and initial separation of the sheets in the stack.
Other objects will be in part obvious and in part pointed out in more detail hereinafter.
These and related objects are accomplished in accordance with the present invention by providing a new and improved tacky mat comprised of a plurality of super-imposed tacky mat sheets each having a composite laminar construction. The sheets consist of a thin, highly flexible support film forming an adhesive barrier surface on the underside of the sheet, a reinforcing fibrous web coextensive with the support film and firmly secured thereto and a pressure-sensitive adhesive coating carried by the support film, the adhesive coating being in secure engagement with the reinforcing fibrous web. The adhesive coating penetrates and embeds the fibrous web therein and assures unified cooperative action between the supporting film and the reinforcing web.
A better understanding of the objects, advantages, features, properties and relationships of the invention will be obtained from the following detailed description and the accompanying drawing which set forth an illustrative embodiment indicative of the way in which the principles of the invention are employed.
BRIEF DESCRIPTION OF THE DRAWING In the drawing:
FIG. 1 is a perspective view of an embodiment of the tacky mat stack of the present invention mounted within a suitable frame;
FIG. 2 is an exploded perspective view of the tacky mat stack of FIG. 1 with a portion of the frame broken away and some of the mat sheets arranged to show both their top and bottom surfaces;
FIG. 3 is an enlarged sectional view taken along the line 3- 3 of FIG. 2 illustrating the composite laminar construction of a single mat sheet; and
FIG. 4 is an enlarged perspective view of the improved pull tab portion of the tacky mat stack illustrating the ease with which an overlying adhesive sheet can be removed from the stack.
DESCRIPTION OF A PREFERRED EMBODIMENT Referring now to the drawing in greater detail wherein like reference numerals indicate like parts throughout the several figures, a tacky mat assembly 10 is illustrated as being comprised of a generally rectangular mat stack 12 of flat superimposed adhesive sheet material securely mounted within an appropriate frame member 14. Although the particular frame used with the stack may be of the type described in greater detail in my earlier US. Pat. No. 3,083,393, the illustrated frame 14 is of a type having a flat base 16 to which the stack 12 is directly adhered and from which it is subsequently stripped. The frame may be made of any suitable material, such as aluminum.
The assembly 10 including the stack 12 of pressure-sensitive adhesive sheets is usually located within a pedestrian traffic passageway and is particularly useful in the industrial field where delicate or dust-free manufacturing operations or techniques are performed or where environmental control is essential, such as in clean rooms and the like. It will, of course, be appreciated that the tacky mat stack of the present invention also has beneficial hospital uses, as at the entry to operating rooms or other areas wherein control of dust particles is desired.
As described in my aforementioned patents, the stack may be mounted on a flat, generally rectangular base member, such as a masonite board having dimensions slightly greater than the adhesive sheets carried thereby. However, as illustrated in FIG. 2, the stack 12 of the present invention is advantageously applied directly to the base 16 of the frame 14 and fully removed therefrom in a sequential manner after use of each uppermost sheet.
The lowermost adhesive sheet 18 of the stack 12 is generally of the type described in my earlier patents in that it is double faced with adhesive while the remaining or overlying sheets 20 are substantially identical, have adhesive on only the tread surface thereof and incorporate the composite laminar sheet construction of the present invention. The bottom surface 24 of lowermost sheet 18 is provided with a full coating of highly tacky adhesive for securely attaching that sheet to the base 16 of the frame. As will be appreciated, the adhesive on the surface 24 preferably possesses greater bonding or adhering power than the adhesive on the top or tread surface 26 of sheet 18 in order to assure firm attachment of the stack to the frame when the superimposed sheets are peeled from the stack.
As mentioned, each of the overlying sheets 20, usually about nine in number, are substantially identical. Accordingly, for ease of illustration and clarity of understanding only one such sheet structure will be described in detail. Unlike the adhesive coated heavy cloth sheets described in my aforementioned patents, the pressure-sensitive adhesive coated sheets 20 of the present invention are composite laminar structures which rely to some degree upon the cooperative and coacting reinforcement of the different components of the structure to provide the desired strength characteristics thereof.
Referring specifically to FIG. 3, each composite adhesive sheet structure 20 is comprised essentially of a thin pliable support film 30 on which rests a fibrous reinforcing web material 32 of gauze-like open weave embedded within a coating 34 of adhesive. In the preferred embodiment illustrated, the adhesive coating 34 extends through the gauze web 32 so as to contact and securely adhere to the support film 30. This effects not only an anchoring or bonding of the gauze-like material to the support but also provides operating unity and integrity between the components of the composite laminar structure. That is, each component of the structure cooperates with the other components to structurally reinforce the sheet.
It will be appreciated that a single layer of gauze-like fabric has only a low degree of tear strength and may readily rip when subjected to a force such as that encountered during sheet separation from the stack. Such low strength material with its open weave would not ordinarily be suited for use as a replacement for the cloth backing used heretofore. By the same token, a thin pliable film of high flexibility and fine gauge is also susceptible to easy rupture and tear. However, in accordance with the present invention the adhesive combination of the weak open-weave gauze-like fabric and the thin pliable film causes cooperative reinforcement of each structural component and mutual reinforcement thereof.
The film 30 utilized as a base or support in the composite laminar structure of the present invention is preferably a thin flexible member having a smooth, fiat, exposed bottom surface 36 that will releasably adhere to the pressure-sensitive adhesive of an underlying sheet yet be impermeable thereto. Thus, the film forms a continuous or uninterrupted barrier which prevents flow of the adhesive therethrough from either above or below the film despite its thin gauge and susceptibility to tearing. The film found to give good results is generally of a thickness no greater than about 0.010 inch and usually of 0.005 inch and less in thickness. Plastic films, such as films of vinyl polymers and copolymers as well as polyethylene and similar materials, possess these desired characteristics. Additionally, the plastic films do not tend to dry up and become brittle with age and exhibit good elongation, pliability and flexibility characteristics coupled with the ability to releasably adhere to the confronting pressure-sensitive adhesive coating of an adjacent underlying sheet. It will, of course, be appreciated that the excellent chemical resistance of such films does not prevent the secure bonding of the open gauze-like fabric to the film by the adhesive coating 34 applied to the top surface thereof.
The fibrous web material 32 embedded within the pressuresensitive adhesive coating 34 and secured to the plastic film thereby is preferably a gauze-like fabric of open-weave construction. However, similar highly porous fibrous structures such as scrims or other nonwoven webs could be utilized in accordance with the present invention to cooperate with the plastic films and provide the desired reinforced strength characteristics needed in the composite sheet.
The particular pressure-sensitive adhesive coating utilized to form the tread surface 38 of each sheet 20 and adhere the web 32 to the film 30 in accordance with the present invention should be of moderate tackiness. It is also necessary that the pressure-sensitive adhesive composition be of the type which retains its tackiness over an extended period of time. Such material is generally of the type found in masking tape and, in essence, is substantially the same as that described in my earlier US. Pat. No. 3,083,393.
An added feature of the present invention is the utilization of pull tabs 42 on one corner of each adhesive surface of the sheets to facilitate stripping of each uppermost sheet from the remainder of the tacky mat stack. In the preferred embodi ment illustrated, this takes the form of a small generally rectangular piece of nontacky material, such as a tough, dimensionally stable polyester film, e. g., Mylar" sold by E. l. du Pont de Nemours, of about 1 mil thickness in firm adhesive contact with the tread surface 38 of each composite sheet structure. The tab 42 is provided with a leaf portion 44 extending beyond the edge of the adhesive sheet and folded back to facilitate easy grasp thereof by those persons responsible for stripping the uppermost sheet from the mat stack. The remainder of the tab, which may contain identifying indicia such as a trademark or the like, is securely fastened to the adhesive sheet and, as will be appreciated, is in confronting relationship with the plastic film on the undersurface of a superimposed sheet so that there is plastic-to-plastic nonadhesive contact therebetween at one comer of each sheet.
The bottom sheet 18 of the stack 12 also is provided with a tab 42 on both adhesive surfaces to assure the presence of an initial stripping area free of adhesive between the sheet 18 and base plate 16 of the frame. Thus, it is quite easy for the operator to merely grasp the folded leaf portion 44 of the exposed tab 42 and lift the uppermost sheet from the underlying member in the area where there is no intervening adhesion. As shown, the tab 42 is of sufficient size to provide a good gripping area and permit continued peeling of the superimposed sheet structure from the stack.
As will be apparent to persons skilled in the art, various modifications, adaptations and variations of the foregoing specific disclosure can be made without departing from the teachings of the present invention.

The tacky mat stack of claim 1 wherein the flexible support film is a thin solid plastic sheet carrying both the reinforcing fibrous web and the adhesive coating, the barrier surface of said film being disposed in overlying confronting relationship with the pressure-sensitive adhesive of an underlying sheet and being releasably held thereby to prevent relative movement therebetween while facilitating peelable separation therefrom.
- 3. The mat stack of claim 2 wherein the film of plastic has a thickness less than 0.01 inch.
- 4. The mat stack of claim 1 wherein the fibrous web exhibits an open, gauze-like network facilitating penetration of the adhesive coating therethrough into secure engagement with the support film.
- 5. The mat stack of claim 1 wherein the fibrous web is embedded in the pressure-sensitive adhesive coating and secured to the film by said coating.
- 6. The mat stack of claim 1 wherein a portion of the tread surface is provided with a gripping member engaging one edge of the sheet, said member being in confronting relationship with the barrier surface of an overlying sheet to provide constant nonadhering contact therebetween at said one edge while facilitating initial separation of the overlying sheet from the stack.
- 7. In a tacky mat stack suited for the passage of pedestrian traffic thereacross and the concurrent adhesive removal of dirt particles from said traffic by the tread surface on the uppermost sheet of said stack, the improvement in a plurality of superimposed tacky mat sheets having upwardly facing tread surfaces wherein a portion of the upwardly facing tread surface of each sheet is provided with a pull tab having a gripping portion extending freely from the sheet, each overlying sheet being provided with an integral non-delaminating adhesive barrier extending across essentially the full sheet in confronting arrangement with the upwardly facing adhesive tread surface of the underlying sheet and with said pull tab, said tab extending from the edge of the sheet and cooperating with said confronting barrier to provide constant nonadhesive contAct between superimposed sheets at said edge portion, said gripping portion being interposed between the pull tab and the barrier for exposure upon removal of the overlying sheet.
- 8. The tacky mat stack of claim 7 wherein the sheets are generally rectangular planar members and the pull tab is a plastic film of high tear strength positioned at one corner thereof to prevent adhesion between adjacent sheets at said one corner.
- 9. The mat stack of claim 7 wherein the pull tab is a polyester film of about 1 mil thickness.
- 10. In a tacky mat stack suited for the passage of pedestrian traffic thereacross and the concurrent adhesive removal of dirt particles from said traffic by the tread surface on the uppermost sheet of said stack, the improvement in a plurality of superimposed tacky mat sheets of composite laminar construction wherein each superimposed sheet is comprised of a flexible support film having an integral adhesive-impermeable barrier surface extending across essentially the full underside thereof and a pressure-sensitive adhesive coating carried on the top side of said support film and forming an upwardly facing pressure-sensitive adhesive tread surface of the sheet, said coating being in secure non-delaminating engagement with said support film to provide said composite laminar structure, said barrier surface preventing penetration therethrough of the adhesive tread carried by an underlying sheet and consequent adhesive welding of superimposed sheets during the passage of pedestrian traffic across the stack, said barrier surface facilitating easy separation of each topmost sheet after passage of pedestrian traffic thereon while preventing inadvertent relative movement between the superimposed sheets of the stack.
- 11. The tacky mat stack of claim 10 wherein the flexible support film is a thin solid plastic sheet and the barrier surface of said film is disposed in overlying confronting relationship with the pressure-sensitive adhesive of an underlying sheet and is releasably held thereby to prevent relative movement therebetween while facilitating peelable separation thereof.
- 12. The mat stack of claim 10 wherein one edge of the sheet is provided with gripping means in confronting relationship with the barrier surface of an overlying sheet to provide constant nonadhering contact therebetween at said one edge while facilitating initial separation of the overlying sheet from the stack.
