Abstract: A plastic product is fabricated from plastic sheets by heat sealing the plastic sheets to form an enclosure member. In order to strengthen the heat-sealed joints of the plastic sheets, the plastic sheets are thickened at portions where the heat-sealed joints are to be formed. Preferably, the heat-sealed joints are formed in such a manner that the cross-section of the heat-sealed joints is smaller than that of the thickened portions of the plastic sheet, thereby preventing effectively the non-thickened portions of the plastic sheets from being affected adversely by the heat sealing process.

Abstract: A self-inflating mattress has a hollow body, an inflating valve, a deflating valve, a unidirectional valve and a foam material. The body has at least two chambers respectively serving as a primary chamber with a supporting chamber and a secondary chamber. The inflating and deflating valves are mounted on the body and communicate respectively with the primary and secondary chambers. The unidirectional valve is mounted on the supporting chamber, communicates with the supporting and secondary chambers and only allows air to flow from the primary chamber to the secondary chamber when open. The foam material is mounted in the primary chamber. The operation of the inflation/deflation of the primary and secondary chambers is implemented without an air pump and is convenient. Furthermore, the supporting chamber provides convenience for tightly fitting of the unidirectional valve without any leakage.

Abstract: A self inflatable mattress includes a main portion with a first chamber and a sponge in the first chamber, an extended portion and having a second chamber, a valve mounted on the main portion to allow surrounding air to enter the first chamber and a unidirectional valve received in the extended portion and sandwiched between the first chamber and the second chamber to provide alternate communication between the first chamber and the second chamber. A self expansion of the main portion due to the automatic expansion of the sponge from a compressed state to a non-compressed state allows the surrounding air to enter the first chamber, the air inside the first chamber is able to be forced to enter the second chamber by pushing away the unidirectional valve to resume communication between the first chamber and the second chamber so that the second chamber is inflated.
