Abstract
A tote bag having an inflatable device such as a vinyl pillow integrally connected thereto is described. The inflatable is attached to a side of the tote bag so that the bag con be converted for a head rest when the pillow is inflated. The inflatable can be attached along selected sides leaving a side open to form a pocket between the inflatable and the tote bag.
Description




FIELD OF THE INVENTION




This invention relates to a tote bag that has attached to it a decorative and/or functional inflatable pillow. The pillow can be applied to the inside or outside of the tote bag and when inflated may act as a seat cushion or head pillow.




BACKGROUND OF THE INVENTION




Known in the art are tote bags and carry bags of all description. They are made from a myriad of materials including different types of fabrics such as canvas or nylon, and some are made from plastic materials such as flexible vinyl. Also well known are duffle bags, barrel totes and many others.




Methods for decorating these types of articles would typically be to print on the surface of the products using methods such as screen printing, hand painting, embroidery, vinyl appliques, embossing, heat transfers, foil application and other commonly used methods of embellishment.




These methods of decoration require that the decoration be applied directly to the surface of the article. These decorations are generally only decorations and therefore perform no other useful functions. The article may be decorated on one or both sides.




Also well known in the art are inflatables attached to various fabric products. In my U.S. Pat. No. 5,802,643 I refer to a slipcover, which slips over a lounge chair, and has an inflatable pillow directly sealed to the slipcover. In addition the slipcover may have handles cut into the open end, and when folded it forms a type of a carry bag. The present invention differs from the '643 patent in that with the present invention one starts with an existing tote bag, that does not fit over the back of a lounge chair, and affix an inflatable pillow to the bag.




I have previously obtained two U.S. Pat. Nos. 5,079,788 and 5,251,377 for inflatable appliques for clothing and towels and a method for producing those appliques. These patents describe the production of thermoplastic inflatable appliques applied to clothing and fabrics by sealing applique material parts to the fabric material and cutting away the excess. Because many of the materials and techniques described in those patents are also useful in conjunction with the teachings herein disclosed, they are incorporated by reference.




SUMMARY OF THE INVENTION




With a carry bag in accordance with the invention a quick, simple, inflatable pillow is formed onto a fabric or plastic tote bag or other type of carry bag. Upon arrival at a sporting event the person will have a handy inflatable sports cushion. The inflatable may be decorative in nature, and can be inflated to form a comfortable seating cushion or head pillow.




Accordingly, it is an object of the present invention to provide a pre-decorated inflatable panel as a permanently attached pillow, which can be easily applied to various types of carry bags. Still another object of the invention is to provide a pillow which itself may form an extra pocket on the carry bag. Still another object of the invention is to provide an inflatable cushion for user comfort whether the user be seated or lying down.




Still another object of the invention is to provide a pre-decorated inflatable panel as a permanently attached pillow where the perimeter of the pillow can have a variety of decorative shapes. The shape may conform to a product being advertised on the carry bag, or it may conform to the shape of the artwork on the pillow.




It is still another object of the invention to provide a pre-decorated inflatable panel as a permanently attached pillow where during the manufacturing process, more than two layers of material can be used to make the pillow, the extra layer being an independently printed layer which is laminated to the top pillow layer for ease of printing.




Still another object of the invention is to provide a pre-decorated inflatable panel as a permanently attached pillow where the pillow is not sealed to the bag on all sides, but where a shaped portion extends away from the pillow to further enhance the decorative features of the pillow.




Yet another object of the invention is to provide a pre-decorated inflatable panel as a permanently attached pillow where more than one pillow is attached to the bag for additional pillow comfort such as two pillows back to back on the same bag panel or one each side on opposite panels.




Another object of the invention is to provide a pre-decorated inflatable panel for a carry bag as a permanently attached pillow where the pillow can be attached on the inside or to the outside of the bag.




Yet another object of the invention is to provide a pre-decorated inflatable panel as a permanently attached pillow for a tote bag, where the tote bag itself is made of a thermoplastic material such as vinyl. Only one layer of material needs be added to the tote bag, because one side of the vinyl bag will form the second air impervious layer to form an inflatable pillow.




These and other objectives are achieved by utilizing various air-impervious flexible thermoplastic materials to form inflatable pillows to adorn the tote bags. Thermoplastic materials such as polyethylene, nylon, urethane, rubber and others may be used for the inflatable pillows. However a preferred material is a pinhole-free vinyl or a soft urethane. These materials will generally have a thickness in the range of 0.005″ to 0.020″. R.F. sealing is the most preferred manufacturing method to use to bond the two layers together to form the pillow, although heat, sonic sealing, vulcanizing and other methods may be used.




Urethane is R.F. sealable as is vinyl, and urethane has excellent airtight properties. (Urethane is one of the primary materials used for the air bladders of footballs, soccer balls, basketballs and others.) It is preferable for the vinyl to be “pinhole free”, but this is not necessarily essential. (Pinhole free vinyl costs only slightly more than a standard vinyl.) The preferred thickness of the vinyl or urethane will be in the 0.005″ to 0.020″ range. When utilizing vinyl, the thicker the material, the more air impervious it will be. Thus pinhole free material is not necessarily essential for a successful product if the vinyl used is in the thicker range such as more than 0.012″ in thickness. Furthermore, when a pre-printed sheet is laminated to a top layer, an almost perfect airtight barrier is created to reduce the need for a specific pinhole free material.




In one embodiment in accordance with the invention, a first layer of vinyl bearing a decorative printing on one side, will overlay a second vinyl layer which forms the inside of the pillow. The first layer may be a plain vinyl, which is printed, or a vinyl that is reflective, or glows in the dark, or has a holographic image or has some other background of an interesting nature. It may also be a flocked vinyl for a soft feel and appearance. It may also be a vinyl with a cloth laminated to it to give it a fabric-type surface.




With a decorative pillow added to a tote bag, in accordance with the invention, a variety of shapes can be achieved for the pillow. It can be made in an economic manner and made available with attractive appearances including graphics, reflective features, glow materials or other enhancements as may become desirable.




The preferred article onto which to attach an inflatable pillow is a canvas tote bag, a nylon tote bag, or a vinyl tote bag. However other types of bags may be used where applying an inflatable pillow is functional such as large duffel bags, knapsacks, rugsacks and others.




The invention and its particular features will become more apparent from the following detailed description considered with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE DRAWINGS




With reference to

FIG. 1

a tote bag


10


in accordance with the present invention is shown with an inflatable


15


, such as a rectangular inflatable pillow, is attached to an outside surface


15




a


of the bag


10


. In this depiction, a stem valve


26


is used as the means to inflate air into the pillow


15


and then be sealed closed. The valve stem


26


is created while the pillow


15


is being formed directly on the bag


10


. By placing an insulating material such as a strip of Teflon or release paper on the tote bag


10


at the valve stem area, between opposing layers of vinyl that make the inflatable pillow


15


the valve can be made at the same time the layers are sealed together and to bag


10


. The insulating or release paper assures that the stem


26


will not adhere to bag


10


, even though the inflatable


15


is made to adhere.




Areas of “quilting” made with one or more inner depression patterns, such as


20


, are also shown in FIG.


1


. This quilting pattern serves to anchor part of the inflatable


15


to bag


10


. The quilting pattern further prevents the pillow


15


from totally ballooning up when it is inflated, and thus provide a more comfortable flatter appearance. Openings


21


in the quilting pattern


20


allow air to get to all areas of the pillow


15


so that there are no independent un-inflated chambers. It is understood, however, that if un-inflated areas are desired, these can be made by sealing off certain areas so that air cannot get into these areas.




Area


17


shows an outer inflated area of the pillow, and area


18


shows an inner inflated area. Of course there can be more than one depression pattern


20


, creating more than two inflated areas within a pillow for a more intricate quilting effect.




A gusseted tote bag


11


with its attached inflatable pillow


15


, but with a different quilting configuration is depicted in FIG.


2


. Here small circular depression dots


20


′ create a uniform rounded quilting effect. In this drawing the pillow uses a conventional molded soft plastic recessible valve


25


as shown in FIG.


3


. This valve may appear on the outside of the pillow as shown, or a hole may be pre-cut into the tote bag


11


, so that the valve


25


appears on the underside of the pillow or actually projects into the inside of the tote bag


11


.





FIG. 3

shows a standard molded soft plastic recessible valve


25


, which valves are readily available in the industry. The valve comprises a base


23


, which is sealed to one of the layers of vinyl, which forms the pillow. This is done in a first step before a pillow


15


is formed onto tote bag


10


or


11


. Plug


24


serves to close the valve


25


and thus prevent air from exiting the pillow


15


.

FIG. 4

shows the valve


25


in its recessed position.

FIG. 4

further illustrates the attachment of the pillow


15


to the tote bag


11


by joining the opposing vinyl layers


36


and


37


, which are sealed together at edge


30


. At edge


30


the vinyl material of the lower layer


36


is made to penetrate the interstices of the fabric material that makes up the tote bag


11


for attachment of the pillow


15


to the tote bag


11


. Within the perimeter of edge


30


and below pillow


15


there is a gap


43


that can be used to form a pocket.





FIG. 5

shows a stem valve


26


after it is formed as part of an inflatable pillow


15


. Note that sealing edge


30


holds the pillow onto bag


11


, but the sealing edge


30


is interrupted at


37


where stem


26


protrudes. The lower vinyl layer


36


, the upper vinyl layer


37


form the stem


26


and define a valve opening


27


through which air is added to inflate the pillow


15


.




After inflation, the stem


26


can, as shown in

FIG. 6

, be folded in half, and slid under the pillow


15


into the open or unsealed area


37


. The pressure of the inflated pillow


15


, and the fact that opening


37


is quite tight, will hold the stem


26


in place and prevent it from unfolding and allowing air to escape.





FIG. 7

indicates how tote bag


10


with an inflatable pillow


15


will appear when the pillow


15


is graphically printed at


41


with an advertisement, logo or other design such as a sports team.




Three vinyl layers,


34


,


35


,


36


make up a pillow


15


as indicated in perspective in

FIG. 8



a


and in an exploded view in

FIG. 8



b.


Two layers are generally sufficient, but for ease of production, one may want to print on a more ink receptive outer vinyl layer


34


which is laminated to layer


35


so that together these form a top layer for the pillow


15


. Then when this pair of layers,


34


and


35


, is perimeter sealed to lower layer


36


, an inflatable pillow


15


is formed. Any type of valve, such as valve


25


, can be used to inflate the pillow.




The pillow can easily be attached to the inside of the tote bag


11


as shown in FIG.


9


. In this case the valve


25


can be installed through the fabric layer of the bag


11


and onto the inner surface layer of pillow


15


, this construction avoids a visual interference with the outer appearance of pillow


15


. A vinyl applique, embroidery, screen print, iron-on patch or other decoration


47


may be placed on either side of the tote bag. For least interference with pillow


15


, it is preferable that the decoration


47


be applied to the side opposite to that of pillow


15


.




Tote bag


11


may have pillow


15


attached to it with three sides only.

FIG. 10

shows this configuration so that an additional pocket


40


can be formed on the outside of the tote bag. By attaching only on three sides or with a partial perimeter attachment in case of a non-rectangular shape, an opening


40


allows for items to be accommodated in the pocket. Items are best accommodated when the pillow is not yet inflated. When one is carrying the tote bag, the pillow would normally be in a deflated state.




This additional pocket


40


further adds to the utility of tote bag


11


. The sealing line


30


appears all around pillow


15


in order to make it airtight. But where the pillow


15


attaches to the bag


11


, sealing line


30


will be thicker in width. Where the pillow is used to make a pocket


40


with an opening


40


, the sealing edge


30


is not attached to bag


11


. At the two top corners where the opening


40


to the pocket appears, the seal line may even have an additional reinforcement


44


. Note that to preserve the integrity of pocket


40


the inner embossing lines


20


between the vinyl layers that form the pillow cannot be attached to tote bag


11


. To accomplish this a separation sheet of Teflon or other non-stick material can be placed on the tote bag


11


, under the pillow forming layers, when pillow


15


is being sealed to it. The Teflon will appear below the areas of the inner embossing lines


20


, as well as below the layers at the opening of the pocket area


40


. This will allow the vinyl layers


35


,


36


and


37


to bond to each other at the opening as well as at the inner depression points, but they will not seal to the tote bag wherever the Teflon or separation sheet is present. The Teflon sheet is removed after sealing.




Alternatively pillow


15


can be made independent of the tote bag


11


in a first step, and then the finished pillow can be sealed along its three sides to the tote bag in a second step.





FIG. 11

shows a shaped pillow


16


, which is attached to tote bag


10


. The pillow can be of any shape, but it is obviously preferable that it be large and chunky in nature, so as to provide a pillow of comfort and adequate size. Quilting impressions


48


(previously indicated as


20


in

FIG. 1

, can now appear as part of the design such as within the eyes in design


41


. These impression areas


48


help to provide a more comfortable cushion in that they prevent the inflatable from ballooning.




The design in

FIG. 12

is similar to

FIG. 11

, but in this case not all of the inflatable is sealed to tote bag


10


. Areas


45


, which are the ears of the cow, are free and unattached.


46


shows the shadow caused (shown as an exaggeration) to better depict the meaning of the drawing. Once again, while sealing line


30


goes around the entire inflatable


16


, in the areas where it attaches the inflatable to the tote bag, it may be made slightly thicker for better adherence.


32


represents the part of the sealing edge which is not attached to the Bag.





FIG. 13

shows tote bag


11


with two pillows


15


and


15


′ attached. They may be attached on either side i.e. the inside or the outside of the bag. Two pillows are useful if the user desires a greater degree of comfort. If attached to both outside areas of the tote bag, then two different types of graphics may be displayed. The gusseted base of the tote bag


11


is shown as


11


′.




In

FIG. 14

the die used to make the inflatable pillow has a flat sealing edge. This is useful in two instances:




Firstly, when using a tote bag


12


made of vinyl, only one additional layer needs to be sealed to the tote bag in order to make an inflatable pillow. Upper layer


35


may be printed or if left unprinted, it can be combined with additional printed layer


34


. One or both of these will be pre-cut to the exact desired size, usually by means of die-cutting. These are then placed on tote bag


12


, and the flat edged die


52


is brought down on the bonding machine to bond the layers to the vinyl tote bag


12


to form the inflatable pillow. The valve can be on the inside of the bag, or on the outside of the pillow. Note that with a flat edged die


52


, the inner impression extensions


57


, which provide the quilted effect, are of the same height as the outer sealing edge extensions


58


. The vinyl tote bag


12


forms the lower layer of the pillow. When the pillow is inflated, the tote bag


12


will compress inwards slightly as shown at


12


′.




Secondly, the use of a flat edged die such as die


52


in

FIG. 14

is useful when one is making the inflatable pillow out of a cloth covered vinyl or a reinforced vinyl. In both of these cases, the vinyl, because of the cloth bonded to it, will not “tear-seal”, i.e. seal and cut in one operation. Thus the cloth/vinyl combination will need to first be die-cut to size or shape, and then sealed to the tote bag with flat edged die


52


. This needs to be done whether the tote bag is made of cloth or vinyl.





FIG. 15

in accordance with the invention is a side sectional view of a sealing die. Sealing die


50


depicts a sealing die with no inner impression lines. Shown as part of the die is a sealing edge


55


and a cutting edge


56


. When utilizing the preferred materials vinyl or urethane for the inflatable, these materials with top layer


35


and lower layer


36


enable cutting and sealing in one operation while the inflatable is being formed and being attached to tote bag


10


. Valve


25


is shown on the top of the pillow in this depiction.




Sealing die


51


in

FIG. 16

shows a die as above with seal line


55


and cutting edge


56


, but with inner impression extensions


57


. These impressions will form the quilting effects as indicated at


20


and


48


above. Not shown here but easy to implement is a valve


25


which may be passed through a pre-cut hole in the tote bag


10


. This pre-cutting and directing of the valve through the fabric might be advantageous if one desires the pillow to be on the outside of the tote bag, but where one does not want the valve to interfere with any graphics on the pillow.




For manufacturing, a printed sheet


34


may be laminated to a top layer


35


, or top layer


35


may itself be printed. The combination of these top layers or


35


alone will be placed over lower layer


36


in position onto a tote bag which has already been placed into an R.F. Sealing machine. The tote bag is placed on an anvil so that the back fabric part of the tote bag is not directly under the front fabric portion. The head of the machine comes down. Dies


50


or


51


will have previously been mounted into the head of the machine. The R.F. sealing process will cause the layers to be sealed together, and all excess material will automatically cut away. The die descends onto the materials, and seals the layers together around their perimeters, and embosses any inner seal lines if these are designed into the die. These lines would form the previously described quilting effect at


20


or


48


.




However it is also understood that the inflatable pillow may be made separately and not formed directly on the tote bag. (This is referred to in

FIG. 10

above.) If the pillow is made with a wide sealing edge, then this pre-made pillow may be sewn onto the bag. It may also be glued on, sealed on with heat, attached by velcro, attached by a mechanical fastener or affixed in some other manner so as to form an inflatable pillow/carry bag in one.




Having thus explained and described several embodiments for forming a tote bag with an inflatable pillow the advantages and objects of the invention can be understood. Variations from the invention can be made withut departing from the scope of the invention as defined by the following claims.
