Abstract

PET BED

ABSTRACT OF THE DISCLOSURE
A pet bed having insecticidal properties is formed with a powder-impervious bottom sheet formed of box board material and an upper sheet or layer which is formed of a needled fabric or felt-like material, defining therebetween a pocket or reservoir which contains a powdered insecticide.
When the pet, such as a dog or cat, lies on the upper surface, a small amount of the powdered insecticide is picked up, patted, or rubbed onto the pet's body as it comes into contact with it. This release of the insecticide controls the fleas.

Description

i,.~c~ ouncl of - he ~ ent: ~ on Tllis i.lvcrltion ~el~tes ~c, ~t reds and more part.i-cul~rl~ .o ~ sheet--i.i};e bed which cc~n~airls an enc-psula~ed powdered insecticiA~e and which permits a ~e~.ease of thr insecticide fro~l the res~r~oir poc~et, through the hase --abric, through to the .ibxc)us top or outer material, ancl deposi s the insectici~e onto tlle pet when the ~ed i.s used.
~ lan~ attemp~s nave been made to rid pets, such as dogs and cats, of fleas and flea collars and ~lea cJarmen-ts have been suggestecl, and certain of such devices have come into c~eneral use. Hotlever, most of ~hese deiices fail to provide an insect:icide wilich is effecti.ve at the regions which are most likely to he infested, th~t is, t-~;e d~r.t;, moist and/or warm r~gions of the pet, particularly when the pet is restin~ or sleeping.
A flea collar incorporating a powdered inseGtici~e is shown in Peo, U. S. patent No. 2,734,483 of 1956. Collars of the type shown in Peo must ~e worn by the pet to be e.-fec-tive. A f~migatioll garment which also must be worn to be effective is shown in Norvig, U. S. patent No. 2,408,575 of 1946. A pot7der puff type of hand-held applicator is shown in Duffey, U. S . patent No. 2,762,158 OL 1956, in which fa~rics are joined-to form a mit~ e ba~ con~ailiing a pow-dered insecticide which is applied to the animal by patting the mit against the animal to release the insecticidc.
In Burt, U. S. patent No. 1,569,710 of 1926, an absor~ent or porous mat formed of chenille is saturated with an insecticide. There is no suggestion in Burt of an.essen-tially tw~-piece constructior. with an impervlous bottom l~-yer and a po~ous upper layer to r.if--rmit passage or release o~ a powdered insectici~ ther~through.

1~)4S4Bl Pet beds, per se, not having any means for contain-ing or applying a powdered insecticide, are shown in Bramley, U.S. Patent No. 3,066,646 of 1962 and Pohl, U.S. Patent No. 3,565,040 of 1971.
Summarv of the Invention -The invention in one aspect provides a pet bed having insecticidal properties comprising a relatively impervious bottom sheet-like layer and an upper relatively porous fabric-like covering joined marginally with said bottom layer and being unattached to said bottom layer inwardly of the margins thereof; said covering having a non-woven batting at the upper surface thereof intimately joined to a woven fabric base pro-viding a porosity to permit the passage of powdered insecticide therethrough, and a quantity of powdered insecticide received between said covering and said bottom layer so that said powder can penetrate through said covering and come into contact with a pet lying or resting on said upper surface thereof. The lower layer may comprise a sheet or corrugatea box board back-ing, while the upper layer is pre~erably a needled fabric.
This fabric is preferably a needled batt-on-base fabric so that it presents an upper non-woven batting surface, the ; fibers of which are intermittently connected and locked to an inner or lower woven warp and weft. It defines with the box board backing a pocket for containing the powdered insecticide.
The needled upper layer defines a relatively soft wear and stain resistant bedding surface. When the pet lies on the bed its warm body parts are in direct contact with the bedding surface. These are the regions which the flea will normally migrate to, and thus the powder which is released through the upper layer will be most effective in controlling infestations of flea~ on the pet. Also, the bed, ~ecause of ~' ~4548~!
its built-in insecticide supp~y, contains an automatic deter-rent to fleas congregating and being attracted to the pet's quarters.
The parts making up the pet bed of the present inven-tion are relatively low cost, compact, durable, neat - 3a -and attractive. I~ l,ecl is provide~ J-!v .ni~ invention which may be used i.n a dcs hous~ o~^ thc li;;c and whicll retaills its effcctiveness ovcr a ;C.^~5 -~erio~ ol t;ime. A construction is pro~ided by n~e2ns o whic~ the bec1 ccm ~e foided into a small package for ease of .shipment a;ld handling.

Descxit~l:ion of the Preferred Emboc~ir~lent ~ pet bed 10 according to the present inventior. is illustrated as including a powder-impervious bottom layer 11 and an overlying top layer 12. The bottom layer 11 pxe-ferably consists of a die-cut sheet of corrugated box board material. The upper or overlying layer 12 consists of a porous clsth-like material. The upper layer 12 is formed with essentially the same dimensions as the bottom layer 11, and is joined to the layer 11 at the margins thereof by a hot melt adhesive illustratea generally at 14 in Flg. 2. Thus, - the m~tjor areas of the layers are no~ joined to each other, btlt defirle a thin space or pocket which is su~.>s~antially coextensive with the layers.

11)45481 The upper layer 12 is preferably a needled fabric consisting of an inn~r woven portion i.llustrated generally at 15 in Fig. 5, and an upper surface comprising a layer of non-woven batting 16 which has been intimately joined and locked to the fabric by needling in a needling loom to pro-vide a nap-like absorbent and relatively soft upper surface.
The needling provides a completed fabric in which many of the fibers are thickness-oriented. The fabric may have a thickness of from 1/8 to 1/4 inch or more, and the needling provides a controlled porosity which permits a powder-llke material to pass therethrough, when the upper layer is tapped, rubbed or patted. Such a needled fa~ric may be constructed in a manner similar to that by which relatively heavy papermaker's felts are constructed, as shown, for example, in U. S. patent Nos. 950,950 and 2,943,379, and British patent No. 9~9;93~. T~ has ~een fou~d th?t m?'e~ials comprising a blend of wood and synthetic of weiyht is satis-factory to permit a release of insecticide powder through the pores thereof to the upper mat surface 16 of the upper layer 12.

One marginal edge as illustrated by the edge 17 in Fig. 2 is initially allowed to remain open, and suitable flea powder ~,aterial in inserted into the pocket or reser-~oir space formed between the layers 11 and 12. Such 25 material is illustrated in exaygerated thickness at 20 in Fig. 5, although a small quantity of only 1/4 to 2 ounces per square foot has been found to be effective. The powder is thus encapsulated in a thin layer between the upper and lower portions of the be-~ding, and then the maryinal edge 16 - 30 is sealed to close the poc~.et and thus enclose and encapsulate the powder 20.

.

~)45481 A wide variety o~ safe and effective powder-type insec-ticides, which may also incorporate a fungicide, may be used.
One material which has been fourld to be effective consists of 95g inert powder filler and 5% carbaryl (l-naphthyl N methyl-carbamate).
To facilitate the foldlng of the completed pet bed 10into a smaller pac~age for shipping, the lower layer 11 may be scored for folding as indicated by ~he broken lines 22 and 23 in Fig. 3. Further, a dart or partial cutout 25 may be formed in the lower layer 11 as shown in Fig. 2 to facilitate the folding of the completed bed 10 into a small package for shipment. The first fold is along the axis of the line 22 to form a partially folded package as shown in Fig. 3, while a second fold is along the lines 23 to form a compact package for shipment with the outer felted layer being exposed as shown in Fig. 4.
It will therefore be seen that this invention provides a pet bed which may be placed in a dog house or a-garage or the like which provides an upper absorbent surface which is soft and comfortable to the pet. The upper surface is also tough and resistant to scratching and to the natural inclination of dogs to "make a bed" when they lie down.
An impact on the upper layer 12 is sufficient to drive a small quantity of the powder material 20 through the pores of the material. Since the wa~n and often the moist parts of the pet are lying flat against the batting, the insecticide is thus most effective where it needs to be effective to kill the fleas which naturally migrate toward such warm and/or moist regions.
While the form of apparatus herein described constitutes a preferred embodiment of this invention, it is to be under~tood that the invention is not limited to this precise forrn of appa-ratus, and th~t charlges may be made therein without departing - from the scope of the invention.
