Field of the Invention Insect repellant assembly.

2. Description of the Prior Art In the past few years, numerous volatile liquid organic materials have been developed that tend to repel insects such as mosquitos and the like. Such materials may be distributed in an area that is to be protected from insects by being sprayed on surfaces adjacent thereto, or into the air as an aerosol mist. Also, such materials, if they are non-toxic, may be applied to the skin or garments of the user.

However, such methods of application are unsatisfactory, in that when the repellant is applied to the skin it is at least partially absorbed into the body of the user, and this absorbed portion, of course, being ineffective in repelling insects. There is some evidence that volatile liquids used as repellants whether toxic or nontoxic on the skin and absorbed into the body of the user create damaging residual factors in the health of the user. When the repellant is applied to a surface, the surface may be too far from the user for the repellant to be effective in protecting him, and this is likewise true of applying the repellant as an aerosol spray, for even a light wind or breeze will dissipate the aerosol mist to render the same ineffective against insects.

The primary purpose in devising the present invention is to supply a simple, inexpensive insect repellant assembly that may be removably secured to the garment or a desired body portion of a user and with the assurance that the part of the users body adjacent the assembly will be protected from the biting action of insects, such as mosquitos, gnats and the like.

SUMMARY OF THE INVENTION The insect repellant assembly includes a relatively small absorbant pad which pad contains a volatile insect repellant, with the pad secured to the first side of a pliable barrier sheet, and the second side of the sheet being coated with a film of a pressure sensitive adhesive. A number of protective sheets are provided, which prior to the assembly being used are secured thereto, and extend over the absorbant pad and the film of adhesive to protect the same from inadvertent contact by a user. When the device is used, the protective sheets are peeled therefrom, and the barrier sheets and supported pad are removably secured to a desired portion of a person that is to be protected from insects, or a desired location on a persons garment. When the assembly is so applied, the volatile liquid repellant evaporates slowly from the pad, and to the extent that insects such as mosquitos, gnats or the like are discouraged from coming close to the portion of the user on which the assembly is removably mounted. After the assembly has served its intended purpose, it is removed, and discarded.

DESCRIPTION OF THE PREFERRED EMBODIMENT A first form A of the flying insect repellant assembly is shown in FIG. 1, where it will be seen that the invention includes an elongate pad 10 that is centered on an elongate pliable barrier sheet 12. The pad 10 when so disposed on the sheet 12 covers only a portion of a first upper surface thereof, and the sheet 12 accordingly has uncovered end portions 12a as shown in FIG. 2. The pad 10 contains a quantity of a volatile liquid insect repellant (not shown) of the type such as is presently commercially available which may contain the following organic insect repellant material N-diethyl-metatoluamide.

The barrier strip 12 is impervious to the liquid insect repellant (not shown), and prevents the repellant being absorbed by the skin of the user.

The surface end portions 12a have end portions of two protective pliable strips 14 and 14a secured thereto by conventional means, with the protective sheets overlapping the adjacent end portions of the second sheets 14a as illustrated in FIG. 1 and being removably secured thereto by a pressure sensitive adhesive (not shown). The second side of the barrier sheet 12 as may best be seen in FIG. 3 is coated with a film 16 of a pressure sensitive adhesive. Two second sheets 18 and 18a are secured to the barrier sheet end portions 12a as may be seen in FIG. 2, and overlap one another at substantially the center of the pad 10, and are removably secured to one another by pressure sensitive adhesive (not shown). When it is desired to use the first form A of the invention, the sheets 14 and 14a are stripped therefrom, as are the protective sheets 18 and 18a. The pad 10 and barrier sheet 12 as shown in FIG. 3 may then be removably secured to a desired body portion of the skin of a user (not shown) or a users garment (not shown), with the volatile insect repellant thereafter evaporating from the pad 10 to discourage insects lighting on or biting a portion of the user (not shown) adjacent the pad 10. The protective sheets 14 and 14a, and 18 and 18a serve to protect the pad 10 and pressure sensitive adhesive film 16 being inadvertently contacted by user (not shown) prior to the first form A.

The second form B of the invention is shown in FIG. 4 that includes an elongate pad of an absorbent material that contains a volatile liquid insect repellant (not shown) and this pad being of less length than a rectangular pliable sheet 22 that is impervious to the repellant and on which the pad 20 is mounted and secured thereto by conventional means (not shown).

The pad 20 only partially covers the first surface of the barrier sheet 22 and as a result the barrier sheet 22 has uncovered end portion 22a. The barrier sheet 22 on a second side thereof is covered with a film 24 of a pressure sensitive adhesive. The second form B of the invention as may best be seen in FIGS. 4 and 6 includes a rectangular frame 26 that extends around the pad 20, the frame being secured to the first side of the barrier sheet 22 by conventional means, and the frame formed from a material impervious to the repellant. The second form B of the invention also includes a first pair of protective sheets 28 and 28a that have end portions thereof secured to the ends 22a of the barrier sheet as shown in FIG. 6, with a portion of the protective sheet 28a overlapping the protective sheet 28 and being removably secured thereto by pressure sensitive adhesive means (not shown). A second pair of

protective sheets

30 and 30a have the end portions thereof secured to the second surfaces of the barrier sheet 22, with the sheet 30a extending over the sheet 30 and removably secured thereto by a pressure sensitive adhesive (not shown). When the protective sheets are disposed as shown in FIG. 6 the sheets 28 and 28a cooperate with the frame 26 and barrier sheet 22 to completely envelope the pad 20 and prevent the volatile insect repellant (not shown) evaporating therefrom.

When it is desired to use the second form B of the invention, the

protective strips

28, 28a and 30 and 30a are peeled therefrom and discarded, with the barrier sheet 22, frame 26 and pad 20 being removably secured as a unit to a desired portion of a user or a users garment. When the second form B of the invention is so mounted on the user or the users garment the volatile insect repellant evaporates from the pad 20 and discourages flying insects such as mosquitos, flies or the like from coming into contact with the user or users garments, on which the second form B of the invention is mounted.

A third form C of the invention is shown in FIG. 7 that includes an absorbant pad 32 that contains a volatile liquid insect repellant, with the pad being encased in an envelope 34 formed from a rigid plastic material or the like that is secured to a first surface 36 of a barrier sheet 38 that is formed from a pliable sheet material. The second surface of the barrier sheet 38 is coated with a pressure sensitive adhesive 40 to permit the assembly C to be removably secured to a desired portion of a user or users garment (not shown). The envelope 34, if desired, may have weakened areas 42 formed therein that may be punched out when the invention C is desired to be used to permit the volatile liquid insect repellant to escape from the pad 32 as a vapor. Such vapor discourages the approach of flying insects to the portion of a user or users garments on which the third form C of the invention is mounted.

A fourth form D of the invention is illustrated in FIG. 9 that includes a circular pad 44 that contains a volatile liquid insect repellant (not shown) with the pad being disposed within the confines of a circular rigid frame 46 that has two generally semicircular protective sheets 48 and 48a secured to the upper first surface 50 thereof, with the sheet 48a overlapping the sheet 48 and being removably secured thereto by a pressure sensitive adhesive (not shown). The second surface 52 of the ring 46 has a barrier sheet 54 secured thereto which barrier sheet on the lower surface thereof, as viewed in F IG. 9, is coated with a pressure sensitive adhesive 55.

Two protective sheets 56 and 56a are secured to peripheral edge portions of the sheet 54, with the second sheet 56a overlapping the first sheet 56 and being removably secured thereto by pressure sensitive adhesive. When it is desired to use the fourth form D of the invention, the

protective sheets

48 and 48a and 56 and 56a are peeled therefrom to expose the pressure sensitive film 55, which film is used to removably secure the fourth form D of the invention to a desired body portion of the user or users garments (not shown). The volatile liquid repellant evaporates from the pad 44 when the invention D is so mounted on a user or users garment, and in the vapor thereof discourages flying insects such as mosquitos, gnats, or the like from approaching the user.

It will be particularly noted in both the second, third and fourth forms of the invention that the volatile liquid repellant is sealed from contact with the ambient atmosphere and as a result there is little or no loss of the repellant prior to the time the invention is placed in an operable condition on a desired portion of a user or users body as previously described.

Although the invention has been illustrated and described in four different forms it will be apparent that these forms may be of other shapes if desired such as a triangular, ellipse or the like and still operate in the same manner as previously described.

The use and operation of the invention has been described previously in detail and need not be repeated.
