Abstract

The present invention is to provide an inflatable bag comprising an airtight container, a cavity and a light-emitting unit. The cavity is formed at a top of the container. The cavity comprises a top opening flush with the top of the container, the opening being in communication with the container and the external. The light-emitting unit is mounted in the cavity by inserting through the opening. The light-emitting unit comprises a battery, a light-emitting member provided at a bottom in the cavity distal the opening, and a switch provided at a top projecting from the cavity. The battery is not electrically connected to the light-emitting member after inflating the container to a predetermined shape. The bag is adapted to emit light only by pressing the switch projected from the container to electrically connect the battery to the light-emitting member.

Claims

1. An inflatable bag comprising:

an airtight container;

a cavity formed at a top of the container, the cavity including a top opening flush with the top of the container, the opening being in communication with the container and the external; and

a light-emitting unit mounted in the cavity by inserting through the opening, the light-emitting unit including a battery, a light-emitting member provided at a bottom in the cavity distal the opening, and a switch provided at a top projecting from the cavity;

wherein the switch is adapted to press to electrically connect the battery to the light-emitting member for emitting light or not.

2. The inflatable bag of claim 1, wherein the container comprises a peripheral first sealing member on its inner surface, the cavity further comprises a peripheral second sealing member on its inner surface adjacent the opening, a surface of the cavity is sealed by the first sealing member at a position adjacent the opening, and an airtight, hollow bag is formed by both the container and the cavity with the opening being in communication with the container and the external.

3. The inflatable bag of claim 2, wherein the container further comprises at least one valve formed on its surface.

4. The inflatable bag of claim 3, further comprising predetermined patterns or characters formed on the surface of the container by printing or adhering, and wherein the patterns or the characters are formed on transparent portions of the container with other portions of the container being formed as opaque by printing or adhering.

5. The inflatable bag of claim 3, further comprising predetermined patterns or characters formed on the surface of the container by printing or adhering, and wherein the patterns or the characters are formed on opaque portions of the container by printing or adhering with other portions of the container being formed as transparent.

6. The inflatable bag of claim 2, wherein the light-emitting unit further comprises a tube having one portion concealed by the cavity and the other portion projecting from the opening, the light-emitting member is provided at an underside of the tube within the cavity, the switch is provided above the tube projecting from the opening, and the battery is received in the tube.

7. The inflatable bag of claim 2, wherein the light-emitting unit further comprises:

a sleeve concealed by the cavity, the sleeve adapted to receive the battery with the light-emitting member being provided at an underside of the sleeve distal the opening; and

a cap releasably secured to the sleeve and projected from the opening with the switch being provided above the cap proximate the opening.
