Patent number: 8214953Abstract: A self-enclosable inflatable mattress has a mattress body, a valve and a bag. The mattress body has a sidewall and a chamber being defined in the mattress body. The valve is mounted through the mattress body. The bag is attached to the mattress body and has a surrounding sheet, at least one holding sheet and at least one fastener. The at least one holding sheet is mounted on a corresponding margin of the surrounding sheet and detachably connected to a corresponding surrounding sheet. The fastener is mounted between the surrounding sheet and the holding sheet. The self-enclosable inflatable mattress is easily stored compactly and prevents dust from contacting the mattress body during storage.Type: GrantFiled: June 1, 2009Date of Patent: July 10, 2012Assignee: Team Worldwide Corp.Inventor: Cheng-Chung Wang

Publication number: 20080105366Abstract: An envelope is made by at least heat sealing two face sheets. Each face sheet has thick marginal parts and spaced apart thick connection parts. The envelope has at least one heat-sealed peripheral joint, and a plurality of spaced apart heat-sealed seams. The heat-sealed seams are provided on the thick connection parts, and the heat-sealed peripheral joint is provided on the thick marginal parts. The thick connection parts have spaced apart longitudinal strips, and at least one transverse strip extending transversely of the longitudinal strips and interconnecting at least two of the longitudinal strips.Type: ApplicationFiled: October 31, 2007Publication date: May 8, 2008Applicant: TEAM WORLDWIDE CORP.Inventor: Cheng-Chung WANG

Patent number: 7306694Abstract: 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.Type: GrantFiled: August 12, 2004Date of Patent: December 11, 2007Assignee: Team Worldwide Corp.Inventor: Cheng-Chung Wang

Patent number: 6120264Abstract: An air pump includes a first sheet, a second sheet, an inflation valve and a check valve. The second sheet is directly connected to the first sheet so as to form a chamber. The inflation valve is provided on the chamber to lead air into the chamber when the chamber is extended. The check valve is also provided on the chamber to discharge the air in the chamber when the chamber is compressed. The air pump can be built in an inflatable product.Type: GrantFiled: June 11, 1999Date of Patent: September 19, 2000Assignee: Team Worldwide Corp.Inventor: Kenneth Wang

Patent number: 6007667Abstract: By means of the interlocking methods skillful applying on the combination of the blanks, the supporting structures of the inflation products are easily constructed by these complementary blanks, and the same features of these products can be achieved by the economical usage of the sheet bars. Also, the strength of these products can be increased by the multiple supporting area of the interlocked blanks. This interlocking methods can be not only satisfied the all purposes of the inflation products but also met the standards of the environmental requirements because of its less scraps.Type: GrantFiled: January 24, 1997Date of Patent: December 28, 1999Assignee: Team Worldwide Corp.Inventor: Kenneth Wang

Patent number: 6004116Abstract: An automatic air pump is built into an inflatable body. The automatic air pump includes a pump body, an air inlet and an air outlet. The pump body is automatically restorable and has an air chamber inside. The air outlet is provided on the pump body to introduce air into the inflatable body when the pump body is pressed. The air inlet is provided on the inflatable body to suck air outside the inflatable body into the pump body when the pump body is released.Type: GrantFiled: November 17, 1997Date of Patent: December 21, 1999Assignee: Team Worldwide Corp.Inventor: Kenneth Wang

Patent number: 5102365Abstract: Disclosed is an inflatable ball including at least an upper layer, a lower layer and an intermediate layer of flexible sheets, which are overlapped and heat-sealed together along their circumferences so as to form an inflatable upper chamber between the upper and intermediate layers, and an inflatable lower chamber between the lower and intermediate layers. The intermediate layer is made to contract in its heat-sealed circumference after heat sealing, thus obtaining an improved inflatable ball which requires smaller inflation pressure, and which results in smaller deformation in its upper and lower layers in an inflated state.Type: GrantFiled: April 8, 1991Date of Patent: April 7, 1992Assignee: Team Worldwide Corp.Inventor: Cheng-Chung Wang
