Abstract

The invention discloses a self-sealing valve as well as an inflatable product comprising same and a manufacturing method thereof, wherein the self-sealing valve comprises a plastic part for forming a gas channel; the plastic part comprises an inner side end part, an outer side end part, an inflating opening and an outer opening, wherein in inflating and sealing states, the inner side end part can be positioned in an inflatable body, and in a deflating state, can be positioned outside the inflatable body by being turned over through the gas channel; the outer side end part is positioned on the outer part of the inflatable body; the inflating opening is formed by the inner side end part; the outer opening is formed by the outer side end part; and the dimension of the outer opening can be set to be greater than or smaller than that of the inflating opening. By changing the dimension and the shape of the outer opening, the dimension of the outer opening can be greater than or smaller than that of the inflating opening, so that inflating, sealing and deflating functions are realized by adopting single self-sealing valve.

Description

technical field

[0001] The present invention relates to balloons, and more particularly to self-sealing valves for inflation and deflation of balloons, inflatable articles including the self-sealing valves, and methods of making the same. Background technique

[0002] Inflatable articles such as balloons typically include an inflatable body for containing gas and an inflation inlet. The inflatable body is made of materials such as rubber or plastic or polyester. Sealing and reuse of inflatable articles after initial inflation is very difficult.

[0003] For balloons used for entertainment, the inflation inlet can be sealed by bundling with strings or by thermoplastic sealing. The way the cords are tied does not provide a good seal, and air in the inflatable body may slowly escape through the inflation inlet. Although the thermoplastic sealing method can obtain a good sealing effect, it seals the inflation inlet at one time, which is not conducive to the repeated utilizati...

Embodiment Construction

[0043] Various embodiments of the invention will be described in more detail below with reference to the accompanying drawings. In the various drawings, the same elements are denoted by the same or similar reference numerals. For the sake of clarity, various parts in the drawings have not been drawn to scale.

[0044] figure 1 (a) to (e) show perspective views of self-sealing valves according to different embodiments of the present invention. exist figure 1 (a), 1(b), 1(d) and figure 1 In (e), the various parts of the self-sealing valve are shown separately for clarity. In actual use, the above-mentioned various parts of the self-sealing valve are integrated. As will be described below, the self-sealing valve will be mounted on the inflation inlet of the inflatable body (eg, a neck integrally formed with the inflatable body for receiving the self-sealing valve).

[0045] In one embodiment, such as figure 1As shown in (a), the self-sealing valve 100 includes an elongated...
