VALVE FOR VESSEL
The innovation described herein generally pertains to a valve for use in allowing material to flow into a vessel. The valve can be constructed from a cylinder of thin-film plastic and can be inserted into and adhered to the inside of a neck of the vessel. Pressure inside of the vessel causes the outlet of the valve to constrict or collapse, preventing material from flowing back through the valve from within the vessel when inflation pressure is removed.
This application relates to and claims the benefit of U.S. Provisional Patent Application Ser. No. 62/836,815 filed on Apr. 22, 2019 entitled “VALVE FOR VESSEL”, which is incorporated herein by reference in its entirety.
TECHNICAL FIELDIn general, the present innovation relates to a valve, and more particularly to a one-way valve for use in inflating a vessel.
BACKGROUNDVessels such as balloons are inflated by providing a pressure to create an airflow through an opening into the vessel. However, typical openings used with such vessels do not prevent the air that is added to the interior of the vessel from escaping once pressure is removed from the opening. Accordingly, an improved device, system, or methodology addressing these concerns is needed.
SUMMARYIn accordance with an embodiment of the subject innovation, a one-way valve is provided for use in allowing a material to flow into a vessel. In an example, the material can be gas that can be, but is not limited to, air or helium and the vessel can be a balloon fabricated from foil (e.g., mylar, etc.), nitrile, or latex. In a particular example, the valve can be constructed from a cylinder-shape of thin-film plastic and can be inserted into and adhered to the inside of a neck of the vessel. The valve can include an inlet and an outlet such that a flow of material into the vessel from the inlet can pass through the outlet. Further, such flow of material causes an increase in pressure inside of the vessel, wherein the increased pressure, when the flow of material from the inlet stops, constricts or collapses the outlet of the valve which prevents material flowing from the vessel.
In accordance with an embodiment of the subject innovation, a valve is provided that includes an inlet portion including an opening at a first end of the valve. The inlet portion extends along a first length, and at least a portion of the inlet portion is cylindrical. The valve further includes a tapered portion that tapers along a second length from a first thickness to a second thickness. The valve further includes an outlet portion having the second thickness, and extending along a third length to a second opening at a second end of the valve. The valve is configured to allow a flow of material, such as a volume of gas, in through the opening, the inlet portion, the tapered portion, the outlet portion, and the second opening into a vessel when an inflation pressure is applied. The flow of material into the vessel increases pressure inside the vessel from a first pressure to a second pressure, and the second pressure causes the outlet portion to constrict and close the second opening to prevent the material from flowing back through the valve from within the vessel when the inflation pressure is removed and the flow of material from the inlet portion stops.
These and other objects of this innovation will be evident when viewed in light of the drawings, detailed description and appended claims.
The innovation may take physical form in certain parts and arrangements of parts, a preferred embodiment of which will be described in detail in the specification and illustrated in the accompanying drawings which form a part hereof, and wherein:
Embodiments of the innovation relate to methods and systems that relate to a one-way valve for use with inflating a vessel. The one-way valve can be disposed within a neck of a vessel. The arrangement of the valve within the neck of the vessel allows the vessel to be inflated by allowing a material to flow into the vessel, while also preventing material from flowing out of the vessel. The subject valve can be used in conjunction with any suitable vessel.
The term “vessel” as used herein including any other formatives of this word can be defined as any container that can hold a material which can include, but is not limited to, a gas or a liquid. For example, a vessel can include a rigid construction that is not malleable or a flexible construction. In particular, a vessel can be a balloon. In other examples, the vessel can be a jar, a jug, a bag, among others.
The term “inflate” as used herein including any other formatives of this word can be defined as an increase of pressure within a vessel from a flow of material. Inflating a vessel with a flow of material can cause the vessel to increase in pressure inside the vessel and, depending on the construction of the vessel, can cause the vessel to expand. In particular, if a flow of material is used to inflate a vessel that is a balloon, the vessel will expand as a result of the increase in pressure within the vessel.
With reference to the drawings, like reference numerals designate identical or corresponding parts throughout the several views. However, the inclusion of like elements in different views does not mean a given embodiment necessarily includes such elements or that all embodiments of the innovation include such elements. The examples and figures are illustrative only and not meant to limit the innovation, which is measured by the scope and spirit of the claims.
The valve 100 can be configured to allow a flow of material to fluidly travel from the first opening 106 to the second opening 112. In certain embodiments, the valve 100 can be fabricated from one piece of material. In another embodiment, the valve 100 can include a first piece that couples to a second piece, wherein the first piece includes the first length 122 and the second length 124 and the second piece includes the third length 126. It is to be appreciated that the first piece and the second piece can be coupled by a heat weld, a glue, or other coupling means.
As shown in
The inlet portion 104, the tapered portion 108, and the outlet portion 110 create a continuous channel through which a flow of material can fluidly travel. When a flow of material such as a volume of gas provided by an inflation pressure enters through the first opening 106 (e.g. a blowing up of a vessel such as a balloon), the valve 100 can allow the flow of material (e.g. air, helium, nitrogen, carbon dioxide, etc.) to enter the first opening 106, through the inlet portion 104, through the tapered portion 108, through the outlet portion 110, and out through the second opening 112 into an interior 120 of the vessel 102. When the flow of material passes through the valve 100 and into the interior 120 of the vessel 102, the pressure inside the vessel 102 increases from a first pressure to a second pressure, wherein the second pressure is higher than the first pressure. For example, if a user is inflating a balloon by blowing air with the user's mouth to pass through the valve 100, the air flows through the valve 100 and into the interior 120 of the balloon, increasing the pressure within the balloon from a first pressure to a second pressure that is higher than the first pressure. The increased pressure within the vessel 102 on the outlet portion 110 of the valve 100 causes the outlet portion 110 to constrict or collapse onto itself which closes and seals the second opening 112 and seals the vessel 102 from losing any flow of material from within the interior 120 when the user stops blowing air into the valve 100. In this manner, the valve 100 creates a self-sealing vessel utilizing the flow of material passing through the valve 100 into the vessel 102 and the pressure within the vessel from the flow of material to seal the second opening 112. When a subsequent flow of material flows in through the valve 100, the flow of material causes the outlet portion 110 to re-open and allow the flow of material to enter the interior 120 of the vessel 102 once again. It is to be appreciated that the subsequent flow of material flows in through the valve 100, the flow of material pressure is higher than the pressure within the vessel 102 in order to re-open the outlet portion 110.

At reference numeral 22, the second end 105 of the cylinder 200 is pinched or compressed to begin forming the outlet portion 110 as displayed in
At reference numeral 24, heat welds 114 are applied to weld portions of the front face of the pinched outlet portion 110 to the rear face of the pinched outlet portion 110 in order to form the width of the outlet portion 110, as displayed in
After the valve 100 is constructed (e.g. as shown in
Once the adhesive 118 is applied to the outer surface 107 of the inlet portion 104 of the valve 100 and/or the inner surface 117 of the neck 116, the valve 100 can be inserted into the neck 116 of the vessel. In an embodiment, the neck 116 can be stretched outward to fit the valve 100 in place. After the valve 100 is in place within the neck 116, a force can be applied to press the inlet portion 104 of the valve 100 against the inside surface of the neck 116 to help the adhesive 118 create a leak-proof bond. In an example, excess adhesive 118 can be wiped away and removed.
In other embodiments, the valve can be placed into the neck 116 prior to applying an adhesive 118. In these embodiments, an application tube or straw is inserted between the inner surface 117 of the neck 116 and the outer surface 107 of the inlet portion 104. The adhesive 118 can then be applied using the application tube/straw around the entire perimeter of the neck 116/valve 100 contact surface to create the leak-proof bond.
In certain embodiments, the vessel 102 can be partially inflated to facilitate insertion of the valve 100 into the neck 116. In such an embodiment, a tube can be inserted through the valve 100 so that one end of the tube is within the interior 120 of the vessel 102 and the other end of the tube is outside of the vessel and the valve 100. Inflation pressure can be applied directly to the vessel 102 or it can be applied through the tube. After the valve 100 has been inserted and secured within the neck 116, the vessel 102 can be compressed to force any material (e.g. air, helium, other gas, etc.) out of the vessel 102 through the tube. For example, a balloon can be flattened to let any air out of the interior 120 of the balloon through the tube. After the balloon is flattened, the tube can be removed. The benefit of this compression processes is to make sure the balloon is flattened prior to being packaged and/or transported for sale.
