FIELD OF INVENTION This invention relates to adhesive tapes and bandages, and particularly to improved adhesive arrangements therefor.

BACKGROUND OF THE INVENTION Conventionaladhesive tapes are available in many types, sizes and shapes, comprising a functional or decorative flexible backing of fabric, paper, plastic, or similar material generally with a somewhatsmooth adhesive coating thereon which is typically pressuresensitive. Other types may, however, include adhesives activated by solvent or heat. In adhesive bandages, an absorbent pad or dressing is provided, with marginal adhesive portions for securing the pad over the intended surface. Strip bandages are typically removed by pulling an edge of a marginal portion so that tape and then pad. and then tape are successively removed. The removal of conventional tapes and bandages with a continuous somewhat smooth adhesive surface very often causes sudden pain or discomfort to the user.

Commercially available bandages and surgical dressings are normally packaged in disposable envelopes and are provided with protective release-coated facings which are removed so as to expose the adhesive prior to use. In adhesive tapes, protective facings are not generally used, except to permit the material to be printed. punched or otherwise manipulated.

US. Pat. No. 2,399,545 shows an adhesive tape char; acterized by equally spaced indents along the-outer edges in order to tear the tape across such indents. This prior art patent also facilitates tape removal by reducing relative to conventional tapes up to fifty percent of the adhesive surface, and provides for various adhesive/no adhesive layers.

SUMMARY OF THE INVENTION It is an object of this invention to provide improved adhesive tapes and bandages which are readily removable with reduced pain or discomfort to the user.

Another object is to provide tapes and bandages with regions of lesser adhesiveness which improve air ventilation and circulation adjacent the skin, while still providing satisfactory adhesion. A further object is to provide a method of converting conventional adhesive tapes and bandages to the improved tapes and bandages of this invention.

The invention features an adhesive tape comprising a backing and a plurality of adhesive layers distributed andadhered to said backing. These layers are alternately spaced with regions of lesser adhesiveness therebetween for applications including the securing of an absorbent pad or dressing about a wound. The adhesive layers and regions of lesser adhesiveness alternate along the tape in theexpected direction of removal from areas adjacent a wound. The criteria of design critical to this invention are chiefly that each region of lesser adhesiveness generally be of width less than each adjacent layer of adhesive and that the minimum width 2 of each region of lesser adhesiveness be approximately 0.02 inches. I

In a preferred strip bandage embodiment, the adhesive layers extend across the entire width of the tape as do the regions of lesser adhesiveness, the adhesive layers and regions of lesser adhesiveness being in the form of alternating parallel stripes. These stripes are preferably of rectangular shape and substantially perpendicular to the longitudinal edges of the tape.

Additionally, tapes with striped layers of adhesive, as

constructed according to theinvention, may provide improved holding for particular combining or supporting applications. These tapes may be double-faced; i.e., adhesive on both sides.

Other objects, features and advantages will be apparent to one skilled in the art from the following description of preferred embodiments of the invention, taken together with the attached drawings thereof, in which:

DESCRIPTION OF THE DRAWINGS FIG. 1 is a diagrammatic plan view of a conventional adhesive strip bandage, with a portion of the somewhat smooth adhesive layer removed to display the backing strip;

FIG. 2 is a diagrammatic plan view of an adhesive strip bandage constructed in accordance with this in- FIG. 6 is a schematic vertically enlarged crosssectional side view of a tape of this invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. I shows a prior art conventional adhesive strip bandage 10 which comprises an absorbent pad 12 (typically, a gauze material) secured to a'tape backing strip 14 with opposed marginal portions 16 and thin edge portions 18 having a continuous somewhat smooth pressure-sensitive adhesivesurface. This bandage is removed by grasping edge 20a of marginal portion 16 and stripping off the contacted bandage from edge 20a to opposing edge 20b.

FIG. 2 shows my improved adhesive strip bandage which similarly contains an absorbent pad 12 and a tape backing strip 14 with opposed marginal portions 26 and edge portions 27 having pressure-sensitive adhesive. Each marginal portion 26, and edge portions 27, however, contain a plurality of generally parallel layers 28 of adhesive and a plurality of generally parallel regions 30 of lesser adhesiveness alternating therebetween, so that layers 28 and regions 30 form a segmented adhesive portion. The regions 30 may be uncoated regions of the tape backingstrip, or an adhesive mixture of lesser adhesivenessthan that in layers 28, or an adhesive, such as that in layers 28, covered with a coating which renders it substantially inert, or permanent facings of lesser adhesiveness overlying and adhering to a somewhat smooth adhesive surface beneath. In all of these constructions, the resultant adhesive portion consists of adhesive layers alternately spaced with regions of lesser adhesiveness therebetween. My adhesive bandage comprising a tape of segmented adhesive portions as in FIG. 2 is removed by pulling an edge 32 of a marginal portion-26 where removal, in fact, is segmented between each successive layer 28 and region 30. The frequencies of stripping in removal are determined by selected adhesive layers which may be of equal, as shown, or of varied'dimensions and the selected regions of lesser adhesiveness which may also be of equal, as shown, or of varied dimensions. Strain upon the contacted skin during removal is thus relieved between each successive adhesive layer and region of lesser adhesiveness, resulting in reduced pain or discomfort to the user.

Satisfactory results are obtained using a width equal to 0.04 inches for each region of lesser adhesiveness with widths of adjacent layers of adhesive equal to 0.10 inches. With such a construction wherein one stripping cycle extends in the direction of removal, from the leading edge of one region of lesser adhesiveness to the corresponding edge of the following region of lesser adhesiveness, one obtains a spatial frequency of stripping equal to approximately v7 cycles per inch. Itshould be noted that these spatial frequencies of stripping need not be constant over any interval greater than one cycle. An expected minimum width for anyregion of lesser adhesiveness is 0.02 inches and the width of any layer of adhesive should not generally exceed 0.25

- inches. A region can have one-or more subdivisions having varying degrees of lesser adhesiveness; i.e., the region need not be uniform in lesser adhesiveness; e.g., a region may have no adhesive in part, and also in part, lesser adhesiveness than an adjacent layer in part.

For providing removal as according to the present invention, the lowerlimit for a constant spatial frequency of stripping over a 1-inch interval is approximately 4 cycles per inch, the upper limit being approximately 25 cycles per' inch. Of course, the invention is not limited to spatial frequencies less than 25 cycles per inch-and may also comprise several different frequencies or ranges of frequencies as already indicated.-

A plurality of ventilation zones across the width of the tape is inherently provided at the regions of lesser adhesiveness, allowing air to circulate more freely about the skin. In prior art conventional bandages, perforations provided through the adhesive and tape backing for such purposes are not interconnected to allow a flow of air between them. Such perforations may, however, also be provided in the embodiment of my invention to provide more effective ventilation. Adhesive bandages and adhesive tapesconstructed according to the invention will additionally provide better body contouring with less strain during movement by gathering of some of the backing material within the regions of lesser adhesiveness.

F IG. 3 shows an adhesive tape constructed in accordance with the present invention with regions of lesser adhesiveness 40 alternately spacedwith adhesive layers 42 therebetween. It will be seen that removal of this tape offersJhe-same advantages as stated for the bandage in FIG. 2. V

.FIG. 4 shows an alternate embodiment of an adhesive strip bandage 44 with an absorbent pad 12 and marginal adhesive portions 46, each of which comprises a series of shortened stripes 48 of lesser adhesiveness. Such bandages offer many of the advantages of the bandage of FIG. 2, particularly ease of removal.

FIG. 5 shows a prior art adhesive tape drawn as a composite of the text and FIGS. 2 and 4 of US. Pat. No. 2,399,545 by B. E. Davis, wherein removal is facilitated by reducing up to 50% of the adhesive surface relative to conventional tapes. This prior art adhesive tape has regions of no adhesive with edge indents for tearing across the tape at prescribed lengths generally indicated asidethe indents on the tape backing. Iridents are uniformly staggered along opposite edges at approximately k inch intervals. Davis only considered tapes having reduced adhesive with the tape shown in FIG. 5 resulting in a constant low spatial frequency of approximately 2 cycles per linear inch. Davis was not aware of the phenomenon of higher frequencies of stripping with associated narrow regions of lesser adhesiveness which is the basis of this invention. The unique removal characteristics of my tape are achieved only at higher frequencies of stripping with regions of lesser adhesiveness contributing to narrow stripping pulses where each region is generally of width less than each adjacentlayer of adhesive, with each region having a minimum width of about 0.02 inches.

The spatial frequency exhibited in the Davis tapes (FIG. 5) is low, while conventional tapes and bandages (FIG. 1) are of zero frequency. My invention comprises an adhesive tape or bandage having high spatial frequencies; e.g., about 4 to 25 cycles per inch, but preferably, 5 to 12 cycles per inch, and in addition, my tapes are characterized by narrow pulse widths. l have found that the combination of higher frequencies with narrow pulse widths provides a remarkable degree of diminution of pain or discomfort to a subject removing such adhesive tapes.

FIG. 6 is a schematic vertically enlarged crosssectional side view of a tape of this invention wherein a conventional tape has been overprinted or coated tional tapes; i.e., tape having a continuous adhesive layer, and adhering them in an adhesive-to-adhesive manner as illustrated in FIG. 6. The tapes of this embodiment comprise a flexible backing with a somewhat smooth adhesive portion or layer with permanent facings; e.g., of thin backing or sheet material of no or lesser adhesiveness overlying and adhering to the adhesive portion. r

My invention has been described in connection with adhesivetape; however, the inventive concepts herein may be employed on any flexible backing having an adhesive coating, and the term adhesive tape" comprises adhesive bandages, gauze rolls and elastic bandages coated with an adhesive coating, etc..

Other embodiments will occur to those skilled in'the art and are within the following claims. 7
