The patent describes a pop-up apparatus designed to lift an object using gas generated within a hollow base unit, which increases internal pressure to elevate a surrounding pop-up unit. The apparatus includes various components such as a holder for the object, a connector plate, and strategically placed exhaust holes to regulate gas flow.

Claim 1

A pop-up apparatus comprising: a base having a hollow portion formed therein; a pop-up portion comprising a lower end and an upper open end such that the base is inserted through the lower end, enclosed by the lower end, and reciprocates with respect to the pop-up portion; a connector plate disposed to cover the upper open end of the pop-up portion; a holder disposed on a first surface of the connector plate and configured to hold an object; and a gas generator arranged in the hollow portion of the base and configured to generate gas, wherein internal pressure of the base increases due to the gas generated from the gas generator thereby lifting the pop-up portion, wherein a second surface of the connector plate opposite to the first surface contacts with an entire edge of the upper open end of the pop-up portion to seal the pop-up portion, wherein the base comprises a lower portion and an upper portion, where the upper portion is disposed closer to the connector plate than the lower portion, wherein the base comprises a plurality of exhaust holes disposed on the side wall of the base, and wherein a number of the plurality of exhaust holes disposed on the upper portion of the base is greater than a number of the plurality of exhaust holes disposed on the lower portion of the base. a base having a hollow portion formed therein; a pop-up portion comprising a lower end and an upper open end such that the base is inserted through the lower end, enclosed by the lower end, and reciprocates with respect to the pop-up portion; a connector plate disposed to cover the upper open end of the pop-up portion; a holder disposed on a first surface of the connector plate and configured to hold an object; and a gas generator arranged in the hollow portion of the base and configured to generate gas, wherein internal pressure of the base increases due to the gas generated from the gas generator thereby lifting the pop-up portion, wherein a second surface of the connector plate opposite to the first surface contacts with an entire edge of the upper open end of the pop-up portion to seal the pop-up portion, wherein the base comprises a lower portion and an upper portion, where the upper portion is disposed closer to the connector plate than the lower portion, wherein the base comprises a plurality of exhaust holes disposed on the side wall of the base, and wherein a number of the plurality of exhaust holes disposed on the upper portion of the base is greater than a number of the plurality of exhaust holes disposed on the lower portion of the base.
