Description

CROSS REFERENCE

This application claims the benefit of the filing date of U.S. Provisional Application Ser. No. 61/289,621, filed Dec. 23, 2009, entitled “Self-Sealing Balloon” the entire disclosure of which is hereby incorporated by reference into the present disclosure.

TECHNICAL FIELD

The inventive subject matter relates to an inflatable device and more particularly to an inflatable device having a pinch-seal closure that may be re-sealable.

BACKGROUND

Toy inflatable devices, such as balloons, are enjoyed by many people of all ages. A factor which limits enjoyment of inflatable devices is sealing the inflatable device after inflating it with water, air or other material. Typically, to seal the inflatable device, a knot is tied at the end. Knotting the inflatable device end may prove to be difficult for children and adults.
In the case of young children or disabled people of any age, they may lack the manual dexterity to tie the knot at the end of the inflatable device. In the case of older children or adults, knotting the inflatable devices may prove to be difficult due to the size of one's fingers relative to the size of the inflatable device end. Further, in situations such as a water balloon fight, the speed with which numerous balloons may be inflated is severely restricted by the speed with which one can seal the balloon.
Another drawback to traditional inflatable device closure methods is that once an inflatable device is knotted, it is destined for a single use. The inflatable device sealed by traditional methods may not be re-used.
There is a need for an inflatable device that is easy to seal by people of all ages and abilities. Further there is a need for an inflatable device that is re-sealable to provide multiple uses of the inflatable device.

DESCRIPTION OF INVENTION

While various aspects of the present invention are described with reference to a particular illustrative embodiment, the invention is not limited to such embodiments, and additional modifications, applications, and embodiments may be implemented without departing from the present invention. In the figures, like reference numbers will be used to illustrate the same components. Those skilled in the art will recognize that the various components set forth herein may be altered without varying from the scope of the inventive subject matter.
FIG. 1 is a plan view of an inflatable device 10 of one embodiment of the inventive subject matter. The inflatable device 10 is a bladder 12 and may be made of any suitable material, including but not limited to rubber, Mylar, plastic, thermoplastic, foil, nylon, vinyl, and many other material variations which are too numerous to mention herein. The bladder may be of any shape or size, the variations of which are also too numerous to mention herein.
The bladder 12 has a closure member 14 for sealing the inflatable device 10 once the bladder 12 has been inflated. In the embodiment shown in FIG. 1, the closure member 14 is on a neck portion 16 of the bladder 12. It should be noted that the neck portion 16 is shown for example purposes only and one skilled in the art is capable of adapting the shape and configuration of the closure member 14 to a particular design shape and configuration of the bladder 12 without departing from the scope of the inventive subject matter.
A cross-section view of an embodiment of the closure member 14 of the inventive subject matter is shown in FIG. 2. At least one rib 18 on a first inner surface 20 of the bladder interlocks with at least one groove 22 on a second inner surface 24 of the bladder 12. The first and second surfaces 20, 24 are facing each other and the ribs 18 and grooves 22 are interconnected by pinching the surfaces 20, 24 of the bladder, thereby creating a seal 32 with minimal dexterity.
Young children, disabled people, and adults alike may seal the bladder easily and effectively. Further, because the interlocking ribs and groves are not permanently deformed upon interlock, the seal may be broken and re-sealed as desired without affecting the integrity of the bladder. Therefore, the bladder inflated and deflated many times. This is particularly advantageous for decorative inflatable devices that may be used on occasion. For example, holidays, birthdays and the like. The inflatable device may be inflated temporarily for the duration of the occasion and then deflated and stored for re-use at a future date.
The closure member 14 may have a color-coded sealing feature. The interlocking ribs 18 on a first surface 20 of the bladder 12 may be a first color 26 and the interlocking grooves 22 on a second inner surface 24 of the bladder 12 may be a second color 28. Referring to FIG. 3, the seal 32 is shown. When the ribs and grooves on each surface 20, 24 are pinched together and become connected forming the seal 32, the two colors merge to form a third color 30.
FIG. 4 is a plan view of another embodiment of the inflatable device 40. In FIG. 4, the bladder 42 is configured with a closure member 44 on the neck portion 46 having adhesive 48 applied thereto. The adhesive 48 is covered by a protective paper until the point in time the bladder 42 is inflated and the seal is initiated. The neck portion 46 remains rolled up during inflation. Upon inflation of the bladder 42, the paper is removed exposing the adhesive 48. The neck portion 46 is unfolded or unrolled as shown in the dashed outline of FIG. 4. The unrolled neck portion 46 is then pinched at the point of the adhesive 48 to create the seal 32 as shown in FIG. 4A. It should be noted that reusability of the adhesive closure member is dependent upon the durability and quality of the adhesive 48. Multiple inflations and deflations may be possible up to the point that the adhesive 38 loses its ability to maintain the seal 32. The inflatable device 40 is shown again in FIG. 5 in an unsealed configuration with the paper 50 shown covering the adhesive.
FIG. 6 is a plan view of another embodiment of the inflatable device 60 of the inventive subject matter. The bladder 62 has a closure member 64 for sealing the inflatable device 60 once the bladder 62 has been inflated. In the embodiment shown in FIG. 5, the closure member 64 is on a neck portion 66 of the bladder 62. It should be noted that the neck portion 66 is shown for example purposes only and one skilled in the art is capable of adapting the shape and configuration of the closure member 64 to a particular design shape and configuration of the bladder 62 without departing from the scope of the inventive subject matter.
A cross-section view of an embodiment of the closure member 64 of the inventive subject matter is shown in FIG. 7. A first plurality of interlocking ribs 68 on a first inner surface 70 of the bladder and second set of interlocking ribs 72 on a second inner surface 74 of the bladder 62. The first and second surfaces 70, 74 are facing each other and the ribs 68 and ribs 72 are interconnected by pinching together the surfaces 70, 74 of the bladder 60 thereby creating a seal with minimal dexterity. Young children, disabled people, and adults alike may seal the bladder easily and effectively. Further, because the interlocking ribs and groves are not permanently deformed upon interlock, the seal may be broken and re-sealed as desired without affecting the integrity of the bladder. Therefore, the bladder inflated and deflated many times. This is particularly advantageous for decorative inflatable devices that may be used on occasion. For example, holidays, birthdays and the like. The inflatable device may be inflated temporarily for the duration of the occasion and then deflated and stored for re-use at a future date.
The closure member 64 may have a color-coded sealing feature as shown in FIGS. 7 and 8. The interlocking ridges on a first surface 70 of the bladder 62 may be a first color 76 and the interlocking ridges on a second inner surface 74 of the bladder 62 may be a second color 78, wherein when the ridges on each surface 70, 74 are pinched and connected, the two colors 76, 78 merge to form a third color 80, see FIG. 8, whose presence indicates a complete seal 32 of the bladder 62 has been created.
In any embodiment of the inventive subject matter, the seal is created without the need for knotting or tying the inflatable device. The inflatable device may be used multiple times without destroying the integrity of the bladder. The seal is created with minimal dexterity. Furthermore, the bladder may be inflated with air, water, helium or other suitable mediums without affecting the ability to seal and re-seal the bladder.
It is an advantage of the inventive subject matter that an easy and effective means for inflating, sealing and deflating an inflatable device is provided. The inventive subject matter is easy for young children, those with disabilities and adults allowing those of all ages and capabilities to enjoy the inflatable device. Another advantage of the inventive subject matter is the ability to re-use the inflatable device multiple times. The closure member of the inventive subject matter allows the inflatable device to be deflated, re-inflated and re-sealed multiple times without destroying the integrity of the bladder.
