INSECT REPELLENT TAPES Filed Sept. 27, 1965 2 Sheets-Sheet 2 INVENTORS MWA/6 ,4/1/05/1/,4/1/ BY MA/1/ 4%?5/144/1/ United States Patent C) Filed Sept. 27, 1965, Ser. No. 490,343 6 Claims. (Cl. i3-4.31)

The present invention relates to an insect repellent tape and it particularly relates to an insect repellent tape which may be readily placed in and around buildings or rooms for insecticidal purposes.

Previous attempts to prepare such materials have not been particularly satisfactory. For example, in British patent, No. 577,124, accepted May 6, 1946, Norman Ernest Hickin, a strip of paper or flexible material was used, coated on one side with a pressure sensitive adhesive and having on the other side a substance or preparation toxic to insects. Due to the lack of absorption in the strip and the nondurability and nonresidual character of the material used, these strips proved ineffective and merely added something to the room which in itself collected dirt and dust and did not aid in insecticidal purposes.

In the Clarke patent, No. 2,720,013, there were carriers affixed to the blades of the fan, but the material was not durable or effective over a long period of time, as a properly prepared absorbent tape would be.

Other prior attempts which also were not satisfactory were embodied in patents: No. 1,161,537, I. W. See, patented November 23, 1915; No. 2,139,225, Reissue No. 21,791, N. P. Easling, reissued May 6, 1941; No. 2,087,- 164, A. D. Purifoy, patented July 13, 1937; No. 2,911,756, R. J. Geary, patented November 10, 1959; No. 2,808,- 679, R. E. Collins, patented October 8, 1957; No. 1,455,- 463, I. J. Weinberg, patented May 15, 1923.

It has been found most satisfactory according to a preferred embodiment of the present invention to provide an absorbent strip 4base material desirably of an absorbent paper which has not been calendered.

This absorbent strip has a loose matted ber construction so that it can absorb at least 70 to 75% of its weight in water, which paper in dry condition is then thoroughly saturated with an oily liquid insecticidal residual material in emulsion form so that there is a thorough penetration in and through the pores of the absorbent materail of the oil residual which upon removal of the water will remain effectively in position.

This absorbent tape material, which may vary from 1A: inch to 1 inch in width and from 5 to 2%,000 of an inch in thickness and which may desirably be of kraft paper base, is then coated on one of its sides with an impervious coating which will prevent removal on that side of any of the residual which has been saturated and dried into the matted fiber of the tape.

To this same side is applied a pressure sensitive adhesive coating of synthetic or natural rubber and will be applied in a thickness not exceeding 1/10 to 1/20 of the thickness of the absorbent paper material. The tape is then desirably coated with a light coating of a resinous material which will permit a slow seepage or evaporation of the residual oil but not any substantial evaporation or removal thereof. Desirably the coating on the top and side edges of the tape should be such that it will penetrate partly into the tape and leave the rough surface exposed.

The preferred residual insecticidal materials are used in the form of 3 to 10% emulsions and include Diazinon (Geigy Agricultural Chemicals), Korlan (The Dow Chemical Company), Chlordane, Lindane, Malathion, Dieldrin (The Dow Chemical Company), and Dicapthon.

In connection with the above type of compounds, the following may be utilized:


Chlordane is an octachloro methano tetrahydroindane and is used as a colorless liquid which is emulsilied in amounts of 3 to 5% in water for the purpose of saturation on the tape.

Dieldrin is a hexachloro epoxy octahydro dimethanonaphthalene. Korlan is a dimethyl trichlorophenyl phosphorothioate.

Desirably these compounds are further saturated upon the absorbent tape in emulsifed condition. The tape will take up between 3 to 10% of the oily residual after the water has been dried therefrom.

In the preferred form of the invention, the paper tape is passed through the emulsion and then is dried in a drier oven between and 180 F.

If desirable, instead of applying a water emulsion, the residual may ybe dissolved in an alternative substance, for example of a volatile hydrocarbon and then such volatile hydrocarbon may be removed by evaporation under heat. However, the water emulsion application with slow drying is preferred.

If desired, 5 to 10% of a heavy oil, desirably a hydrocarbon oil or even a wax, may be utilized to cause retention of the residual on the matted material of the tape after it has been saturated thereon. Nonresidual materials such as pyrethrum are not employed although they may be used for drying purposes.

In this procedure, the tape, after it has been passed through the 3 to 10% emulsion of the residual with full saturation and after part drying or after full drying or at room temperature or under a temperature of 150 to F., may be passed through a powdered material such as pyrethrum to dry the tape.

Preferably, the tape, if it is to be surface dried by a powder, is passed through a saturable powder mixture which is desirably of the nature of the talcum powder containing from 1 to 5% of a residual or a nonresidual insecticidal powder.

After the drying of the tape, it is possi-ble to apply to the upper surface thereof a thin layer of a wettable powder which may be in addition to `a saturable powder already applied in the drying operation. The surface of this tape may be combined with a second lamination or tape upon which there has been absorbed or saturated the emulsion of the residual insecticidal material.

These two tapes of absorbent paper, both saturated and in relatively dry condition, with the residual emulsion, and with the base tape carrying a wettable powder, may then be combined with pressure or by close perforation, which will result in small holes being formed throughout the entire tape construction with the wettable powder being capable of passing onto the upper surface of the upper tape or lamination.

In a less preferred condition, the upper tape lamination may be left free of the residual or insecticidal material so that the only effective application on the top surface of the upper tape wllbe such insecticide that seeps through the closely spaced perforations.

These perforations are desirably spaced between 1/128 to 1/64 of an inch apart over the entire surface and penetrate through both layers of the paper and form openings of hygroscopic size through which a slow release of the residual is achieved.

After the tape has been formed, it is roller coated on its lower face by a suitable resinous material which will prevent any escape of residual or insecticidal material from its lower face. This may be done by roller coating or by spraying.

The preferred resinous material which may be found to act as barriers are epoxy resins and phenol formaldehyde resins which are a flexible composition and which are applied in a thickness of about 1/10 to 1/2 inch in thickness of the paper material.`

The tape is then passed through a light resinous solution desirably such as vinyl resin or polyethylene resin or even nylon which lwill merely form a surfacing without forming a substantial coating layer on the top face and side edges of the paper tape or other absorbent material.

As a final operation, the underside which has been provided with a barrier is coated with the rubber synthetic or natural rubber pressure sensitive adhesive coat- This pressure sensitive adhesive coating may consist of a single layer of a liquid composition five parts by way of rubber, two parts by way of a natural or synthetic resin such as rosin or cumarone resin in which may be employed in dispersion a finely divided dry inert powder such as whiting or zinc oxide in the amount of one-half part to one part by weight.

This tape may be rolled up and later on used in rolled form.

If desired, there may be an inner sheet consisting of a wax paper but it has been found most satisfactory to apply to the surface of the complete tape a light surface of paraffin wax or silicone oil or even a polyethylene condensate such as carbowax which will prevent any adherence between the rubber pressure sensitive adhesive and the effective surface of the insecticidal repellent tape.

In `any case, the layer of paraffin wax or silicone oil should be very thin so as not to effect the slow seepage or discharge of the residual from the body of `the tape.

The tape thus formed should desirably have a thickness not exceeding about 1&4 inch and if desired, the edges of the tape may `be pressure sealed together by heavy pressure rollers so that the only release will be achieved in the central portion of the tape on the top side opposite the pressure sensitive adhesive side.

By suitably protecting the tape in this manner, it is possible to avoid causing any sensitivity or irritability as to the skin of the user, or as to anyone who may be handling the tape as to shipping, merchandising or retailing.

Yet, when the tape is applied, the slow release through the vinyl or polyethylene coating will permit most satisfactory insect repellent properties over a period which may range from one month up to six months.

Normally, the pressure sensitive adhesive coating will become ineffective as an adhesive before the residual effect is lost, and the tape will be removed because of soiling or curling or failure of attachment.

It has been found that such a tape when applied around cracks, corners or crevices will repel roaches, ants, silversh and similar insect life without necessarily killing the same, so that the area is quickly freed of infestation.

The essential feature of the present invention resides in the provision of absorbent paper saturated with an emulsion of the residual with the water removed and with the residual being present throughout the absorbent paper structure, an amount ranging from 1 to 10% and desirably 2 to 5%.

An important feature is also to prevent any destruction of the residual or contamination, thereof by the pressure sensitive adhesive or lthe synthetic or natural rubber base therein. This is achieved by applying a relatively heavy barrier consisting of a flexible resin or varnish coating between the tape or paper carrier and the pressure sensitive adhesive.

To assure slow release of the residual and retention thereof, a very light coat of a permeable resin is applied to the top surface of the tape which will result in a very slow release of the residual repelling the insect, but at the same time not causing any injury or sensitivity as far as the human body is concerned.

This will enable ready application of the tape by the housewife to cover any cracks, corners or crevices or places in and about the room, kitchen or other enclosure which is subject to inset entrance or infestation.

Desirably the top surface may be combined with a material such as a silicone oil or a light surface coating which will be readily separable from the pressure sensitive rubber adhesive coating.

In the drawings:

FIG. 1 is a diagrammatic illustration of the coating procedure;

FIG. 2` is a diagrammatic section showing the various layers of the material which may form the final tape;

FIG. 3 is an alternative tape construction;

FIG. 4 is a top perspective view showing an alternative form of the invention where the insecticide lmaterial is carried in the form of tablets on a carrier tape without being dispersed or absorbed in the body thereof;

FIG. 5 is a diagrammatic perspective view of the corner of a room showing an alternative manner of applying the invention of the present application thereto.

Referring to FIG. l, the vessel 10 will contain an insecticide emulsion 11 of the residual in 3 to 10% strength and the paper tape 1Z is guided into this bath by the rollers 13, 14, 15 and 16. The paper tape will then pass through the drying chamber 17 `to be subjected to blasts of warm air or to infrared lamps which are indicated at 18.

This chamber may be omitted if desired, and the paper passed directly into a container 19 containing a wettable powder. The tape will be guided through this chamber by means of the rollers 20, 21, 22 and 23 and with or without partial drying in the drying chamber 17.

The paper will be thoroughly dried in position 24. It is then subjected to a roller coating operation which will coat the underside with a barrier resin.

As shown, the vessel Z5 contains the barrier resin indicated at 26, and the paper will be passed through the rollers 27 and 28 `and will pick up an under surface of the barrier and which may be dried in position in the drying chamber 29.

The drying in the drying chambers 17 and 29 is so regulated that there will be no substantial loss of the residual and a quick pass over infrared lamps may be used to achieve this.

The paper, then in dry condition, will pass through the vessel 31 on the rollers 32, 33, 34 and 35, where it will pick up a light surfacing of resinous material which will act t0 protect the paper and permit only slow release of the residual material from the tape.

Finally, after drying 0f this additional resinous material in the chamber 36, the tape will be subjected to a final roller cutting operation in which the adhesive 37 will be applied by the roller 3S as the tape is passed under the roller 39.

The guide rollers 40 and 41 will guide it through the rubber sensitive adhesive coating. It may then be passed through a final drying operation, not shown, rolled up and used.

In FIG. 2 is shown a basic tape structure in side section.

The paper or yabsorbent material 50 carried in saturated form 2 to 10% of the residual material, applied as indicated at 11 in FIGURE 1. It has an under layer of a barrier resin 51, applied as indicated at 26 in FIGURE 1, and a base surface 65 of the rubber pressure sensitive adhesive.

The top face as well as the side faces will be covered by a light permeable resinous facing 53 shown applied as a protective coating 31 in FIGURE 1 which will act to slow the release of the residual insecticide and also act to protect the skin of the user.

If desired, there may be a light coating or face 54 of a material which will permit the face 54 to be in contact with the pressure sensitive adhesive 65 and be readily separable therefrom when the material lof FIG. 2 is put up in rolled form and then is unrolled.

In FIG. 3 is shown an alternative tape structure in which there are two base layers 60 and 61. The top base layer may be of a nonpermeable sheet plastic material S such as cellophane. However, in the desired form of the invention both base tape materials dll and dll are formed of the absorbent material of paper which has been saturated with the residual.

Between the layers 60 and 61 there is positioned a wettable powder which may consist of an inert material such as talcum in the amount of 80 to 85% having absorbed thereon a small amount of the residual or other insecticidal material.

These two sheets of paper are then substantially permanently joined together by the fine perforations in dicated at 63.

Where the upper layer 61 is the protective plastic, the coating may be avoided and the residual can be slowly released from the wettable powder 62 and from the lower saturated base tape 60.

However, where both tapes 60 and 61 are saturated with the residual oil, it is desirable to apply a coating such as 53 as in FIG. 2 to assure a slow release. The barrier layer 64 and the pressure sensitive adhesive layer 65 may be applied in the same manner as shown in FIG. 2. v

In FIG. 3, the principal variation consists of the possibility of also utilizing a wettable powder 62 in between the layers 60 and 61 and the possibility of using a top surfacing which will assure slow release through the pin holes or perforations 63.

Where there is no reaction or interaction between the pressure sensitive adhesive 65 and the residual material saturated -on the tape materials 5t) and 60, it is possible to eliminate the barriers S1 and 64, but generally the rubber of most pressure sensitive adhesives will absorb or undesirably affect the residual.

It is thus apparent that the present invention provides a readily applicable durable tape which may be applied either by the housewife or exterininator in and about the kitchen or other rooms to prevent infestations and to repel nondesirable insect life.

By use of a slow release, maximum value is obtained from the residual material in repelling the insect life and in protecting the hands and body portion of the user.

The tape will avoid the applying of injurious dust or sprays in or about living rooms or in rooms where food is prepared or eaten and eliminates any tendency of contamination of persons foodstuffs with sprays, aerosols or liquids.

The residual insecticide will be released at such a rate that it will repel the undesirable insect life for long periods of time as long as the tape is in usable condition.

The tape may be readily utilized in kitchens, food processing plants and the like without special precautions, and it is always readily available and may be used in the desired points ot entry of insect life without waste of insecticide materials over large areas.

One of the most valuable residuals, which will be absorbed and effective for about 3 to 7 months, is Decapthon (0-(2-isopropyl-methyl-ll-pyrimidinyl) phosp'horothioate) which comes as oily concentrate and which emulsifies in water in the proportion of 1 part of the oily concentrate to to 30 parts of water.

By using a tape, yellow staining is prevented.

As an alternative it is possible to roller impregnate a strip of material so that the residual is first added over the entire area of the absorbent tape or strip material and then a central portion or strips may be impregnated with an attractant material which will draw the roaches or `other insects to the.irnpregnated peripheral or edge portions to cause lethal contact.

As attractants, it is possible to use hydroscopic sugar or glucose solutions or molasses or residual solution oontaining sugar. It is also possible to use Dipterex (0.0- dimethyl-2,2,2-trichloro-1 hydroxy ethyl phosphonate) mixed with sugar.

With Dicapthon, a most effective absorbent material is a crinkled` absorbent paper devoid of sizing or finish.

By the surface coating, both the `undesirable odor and the staining are eliminated.

As a covering Afor the absorbent material, it is also possible to use a perforated plastic strip of material as a covering. The plas-tic sheeting or strips would consist of polyethylene, polypropylene, vinyl chloride and/or acetate copolymer, cellulose acetate or butyrate, nylon or polyethylene terephthate (Mylar), which would be caused to adhere to the top surface of absorbent material which would not absorb or react with or polymerize with the residual insecticide.

The important feature of the present invention resides in the fact that an absorbent carrier in the lform of a tape is employed, containing in saturation or near saturation aresidual insecticide, with protection of the insecticide against the gummy adhesive and protection of the insectieide against undue loss by evaporation when in storage or through merchandising.

In the application tothe absorbent tape a preferred l residual is one having an oil or water base, carrying about 4 ounces to a `gallon and of the nature of an oil emulsion or an oil solution, such as an emulsion or solution of chlordane, Diazinon, Entex, Korlan, Lindane, Malathion, Dieldrin and Dicapthon. These are desirably applied in a water emulsion or oil solution containing between 2 and l() ounces per gallon, and are applied by a spray lor roller coating to the absorbent cellulosic or fibrous material, which can absorb up to to 200% by weight of the residual insecticide material. l

These absorbent tapes were actually tried in various restaurants and locations using both insect attractants and repellents, as well as insect killing agents and also using insect killing agents without attractants and without repellents depending upon the effect it is desi-red to achieve.

As typical of 4various constructions lwhich were used and found to be quite satisfactory tis an adhesive tape having a removable paper backing to expose the pressure sensitive adhesive, which tape consisted of' an absorbent material which was impregnated with 1% of Diazinon. This tape was found to prevent entry of roaches and also served Ito leill any roaches which came in contact with or stepped upon the tape.

The same experiment was carried out with 2% of Dicapthon and equally good results were obtained. At the same time other experiments were carried out with tapes which were composed as above which contained as an attractant a dry sugar solution in amount equal to about 1/2 on each of the above tapes. These were found to be particularly elective inasmuch as the roaches were attracted to the tape and then destroyed as the result of contact with the tape.

The above materials Diazinon and Dicapthon are regarded as repellents since when the roaches contacted these lmaterials they would usually withdraw or be repelled and die shortly thereafter or would refuse to come close to the tape and would not cross the same because of its insecticidal properties.

It is also possible to add solidified tablets of the insecticidal material to the tape in addition to or in lieu of the impregnated insecticide. These tablets may each be covered by a suitable protective material.

Referring to FIG. 4, there is shown an alternative form of tape having an absorbent or non-absorbent adhesive backing 3M and a protective strip 302. The strip 3tl2 may be cut off to permit the pressure .sensitive surface 301 to Ibe applied against the wall or floor or a shelf where there is a likelihood of ingress of insects, particularly roaches.

The tablets 303 may be of various shapes, but they desirably consist o'f an insecticidal materia-l such as above set forth, compressed with glucose and Isucrose in the proportion of about 2 to 5% of the insecticidal material and the balance being 'glucose and sucrose, preferably in equal proportions.

Each tablet may be carried on an adhesive facing applied to the upper face 30d` of the carrier strip 3%, or

they may have adhesive coatings `on their lower face, as indicated at 305, to enable them to Ibe firmly attached to the top -tace 304 of the carrier strip 300.

To protect the tablets 303 against deterioration during storage, shipment and `merchandizing, the entire strip of FIG. 4 may be lightly spread with a varnish or protective coating. As an alternative, the entire strip may be covered with a readily removable paper strip having an adhesive or cohesive coating.

In FIG. 5 is shown an alternative form of the invention in which the strips 325, 326, 327 and 328 are applied to the wal-ls 329, 330 and the floor 331, wherethere is likelihood of ingress of insects, such as silversh, roaches and the like through crevices at the corner 332 or at the meeting of the walls and the `tloor 333 and 334. ln this case the strips have an absorbent carrier strip 300, as shown at 300 in FIG. 4, with an under-facing 301 of pressure sensitive adhesive, so that they may 'be readily mounted upon the walls or oors.

Then a formula of theA type above described is spread upon them, as indicated at 335, having the press button 336, the strip being indicated at 337. The adhesive material 300 will pick up the residual insecticide composition and hold it for long periods of time, for example 30 to 90 days and as long as six months, thoroughly protecting the room, closet or chest of drawers, or wherever else tihc strips maybe placed -by the housewife. The same type of strip may also be applied to the strip of FIG. 4, where `the material 300 is of absorbent nature, such as toweling.

Referring to FIG. 6, there is shown a strip which can be applied to the walls, oors or other places to be protected against ingress of insects or roaches, which in the preferred form has a top absorbent strip 350, an intermediate pressure sensitive adhesive strip 351 and a protective under-strip 352.

As a typical formula that may be used for the strip 337, it is possible to employ- Percent Inert Ingredients: Percent Propellant 3.0 t *Equivalent to (butyl carbityl) 6-propyl piperonyl) ether and 0.05% of related compounds 0.20

This type of material will incidentally kill or repel roaches, Water bugs, ants, silversh and the like.

Another typical formula which may be used is- Active ingredients:

Pyrethrins N-octyl bicycloheptene dicarboximide 0,0 diethyl 0-(2-isopropyl-4-methyl 6-pyrimidinyl), phosphorothioate 0.500 Petroleum distillates 96.3l3

Percent 0.037 0.150

Inert ingredients: Percent Propellent 3.000

This formula is particularly suitable for indoor and outdoor ants, roaches and insects.

Another formulation is- Active ingredients: Percent Pyrethrins 0.25 Technical piperonyl butoxide 1.00 Technical methoxychlor 2.00 Petroleum distillates 11.75

Inert ingredients 85.00

Still another formulation is- Active ingredients: Percent 0.0 diethyl 0 (2-isopropyl-4-methyl--pyrimidinyl) phosphorothioate 00.50 Pyrethrins 00.08 N-octyl bicycloheptene dicarboximide 00.25 Technical piperonyl butoxide 00.15 Petroleum distillates 74.02

Inert ingredients:
