Article with expandable bladder
Described is an article comprising a substantially flat piece of material with a first end and a second end. A pocket may be formed at the first end. The pocket may include at least a first opening, and may be configured to receive a bladder. The pocket expands when the bladder is in an expanded state.
When lying on a flat surface, an individual will typically utilize an article, such as, a towel or a blanket, to avoid having to lay directly on a ground (e.g., sand, grass, etc.). The individual may further utilize a pillow or a headrest, for support and comfort of her head. For example, when the individual is lying on a beach, the towel will be placed on the sand and the individual will lie on the towel. However, the individual may not bring the pillow or headrest to the beach in anticipation of having to carry the article from a car to the beach, and vice-versa. Thus, the individual may use a further towel or an article of clothing for support and comfort of her head. However, these items are insufficient to take a place of the pillow. For example, the further towel may not stay in one place relative to the head, and it may not be as comfortable or as supportive as the pillow.
SUMMARY OF THE INVENTIONThe present invention relates to an article comprising a substantially flat piece of material with a first end and a second end. A pocket may be formed at the first end. The pocket may include at least a first opening, and may be configured to receive a bladder. The pocket expands when the bladder is in an expanded state.
BRIEF DESCRIPTION OF THE DRAWINGS
The present invention may be further understood with reference to the following description and the appended drawings, wherein like elements are referred to with the same reference numerals. An exemplary embodiment of the present invention describes an article configured to receive an expandable bladder. Once inside the article, the bladder may be expanded to provide support and comfort for a head of a user, when the user is lying on the article.
In one embodiment, the towel 100 includes a first end 105 and a second end 110. The first end 105 may include a pocket 115 formed therein. In one embodiment, the pocket 115 may be formed by creating a slit 120 in a thickness of the first end 105 of the towel 100. The slit 120, when expanded, forms a first opening 125 for receiving the bladder 200, as will be described below. In another embodiment, the pocket 115 may be formed be attaching a further piece of material to the towel 100. That is, the further piece of material may be placed on the towel 100 in a location where the pocket 115 is to be formed. The material may be stitched and/or attached to the towel 100 in any known manner (e.g., stitched, adhesive, etc.) to create the pocket 115.
Those of skill in the art will understand that the slit 120 may be created anywhere along an edge of the towel 100. That is, although
The pocket 115 may have a predetermined length L2 and a predetermined width W2 which correspond to a size of the bladder 200, as described below. In one embodiment, the pocket width W2 of the pocket 115 may equal the width W1 of the towel 100. For example, as shown more clearly in
In another exemplary embodiment, the pocket 115 further includes a closure arrangement at the first and/or second openings 125, 130. As shown in
An exemplary embodiment of the bladder 200 is shown in
In one embodiment, the bladder 200 may be inflated by a fluid (e.g., a liquid or a gas) to reach the second state. For example, the bladder 200 may include a sealing arrangement 205 which allows the bladder 200 to retain any fluid therein. In another embodiment, the bladder 200 may be filled with a solid substance (e.g., sand) to reach the second state. The sealing arrangement 205 may retain the solid substance within the bladder 200.
The bladder 200 is preferably made from any material which would not degrade with the fluid/substance therein and could expand to the second state. For example, the bladder 200 may be manufactured from a plastic, cloth, canvas, mesh or any other material which is easily cleanable and does not degrade when in contact with the fluid/substance. Further, the bladder 200 may include a predetermined pattern of raised ribs and/or indentations thereon. That is, the ribs may provide additional comfort for the head of the individual.
As shown in
In use, an individual may travel to, for example, a beach intending to use the present invention. One of the advantages of the present invention is realized during travel. For example, the towel 100 may only require a space which would be required for a conventional towel. That is, because the pocket 115 is collapsible and the bladders 200 is removable therefrom, the towel 100 may be rolled up or folded upon itself.
Also, the bladder 200 may be transported while in the first state, and thus, only require a minimal amount of space. That is, any fluid/substance in the bladder 200 may be removed by disengaging the sealing arrangement 205. When empty, the bladder 200 may be rolled up or folded upon itself.
When the individual arrives at the beach, the towel 100 may be unrolled/unfolded and placed on the sand. Then, the bladder 200 may be filled. As described above, in one embodiment, the bladder 200 may be inflated using air or a liquid (e.g., ocean water). In another embodiment, the bladder 200 may be filled using the sand. Further, the bladder 200 may be partially or completely filled depending upon a preference of the individual.
After being filled, the bladder 200 may be inserted into the pocket 115 through one of the first and second openings 125, 130. As described above, the pocket 115 may have dimensions substantially similar to the bladder 200. Thus, when in the pocket 115, vertical movement of the bladder 200 may be prevented. Lateral movement of the bladder 200 may be prevented by the closure arrangement over the first and/or second openings 125, 130.
When the individual is leaving the beach, the bladder 200 may be removed from the pocket 115 and emptied. For example, the male member 310 may be disengaged from the female member 305, and the fluid/substance in the bladder 200 released therefrom. As understood by those of skill in the art, the bladder 200 may be cleaned after use by, for example, filling the bladder 200 with water and releasing the water. Alternatively, the bladder 200 may be turned inside-out and hand and/or machine-washed (e.g., in a conventional washing machine or dishwasher). After being emptied, the bladder 200 and the towel 100 may be rolled up/folded for travel.
In another exemplary embodiment of the present invention, the bladder 200 may be made integral with the towel 100 only exposing the sealing arrangement 205 for filling and emptying. That is, when being manufactured, the pocket 115 may formed in the towel 100, and the bladder 200 may be inserted therein via, for example, the first opening 125. The first opening 125 (and the second opening 130) may be sealed (e.g., stitched, adhesive, etc.) leaving the sealing arrangement 205 exposed from the pocket 115. In this embodiment, a combined towel and bladder may require even less space than a separate towel and bladder, and, the individual may not have to be concerned about losing the bladder 200.
It will be apparent to those skilled in the art that various modifications may be made in the present invention, without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
