Several aspects of this disclosure relate to a reusable kit and it method of use for repairing a leak in a gas-filled inflatable object. In one form, the kit may include: a hollow housing with a leading end region and a trailing end region; a plunger with a front end region and a back end region, the front end region having a tubular nose, the front end region being adapted to be received in the leading end region of the hollow housing; a plug having a head portion and a shaft portion extending therefrom, the shaft portion of the plug being adapted to be mounted at least partially in a tubular nose of the front end region of the plunger; a sealing ring that surrounds the plunger proximate the front end region thereof, the sealing ring serving to interface with an inner wall of the hollow housing; and an adhesive provided below an underside of the head portion of the plug.

Provided are an inflatable product and an inflatable product fusing process. The inflatable product comprises an upper sheet, a lower sheet, pull straps provided therebetween, and upper and lower fixing sheets having one faces away from each other respectively joined with inner surfaces of the upper and lower sheets and one faces facing towards each other not joined. The pull strap has oppositely-provided upper and lower pull strap sheets of porous material. The upper sheet, upper pull strap sheet, upper fixing sheet, lower fixing sheet, lower pull strap sheet and lower sheet are successively provided. When processing using a hot-fusing machine or high-frequency machine, the upper and lower pull strap sheets are simultaneously jointed with the upper and lower fixing sheets, therefore the inflatable product can be one-step formed and no separating sheet needs to be provided in the pull strap, thus simplifying manufacturing process and improving production efficiency.

A fusion structure, an inflatable product having the fusion structure, a manufacturing method thereof, and a rapidly produced inflatable product having a covering layer simultaneously positioned with an inflatable body are provided. The fusion structure of the inflatable product includes a fusion unit, and the fusion unit includes a target fusion layer, a first fusion reinforcement layer and a first auxiliary fusion layer which are fused together. The fusion reinforcement layer and the auxiliary fusion layer are alternately disposed at a side of the target fusion layer, while the outermost layers of two sides of the fusion unit are the target fusion layer and the auxiliary fusion layer. Alternatively, the fusion reinforcement layer and the auxiliary fusion layer are alternately disposed at two sides of the target fusion layer, while the outermost layers of two sides of the fusion unit are auxiliary fusion layers.

A packaging apparatus with an improved pinch roller apparatus, fluid supply apparatus, and/or a sealing apparatus. The pinch roller apparatus (e.g., comprising one or more guide and/or pinch rollers) is used to deliver film material to the fluid supply apparatus (e.g., nozzle and blower apparatus, or the like) that fills one or more chambers of the film material with fluid (e.g., air, gas, or other like fluid), and the film material is then sealed by a sealing apparatus (e.g., using one or more heating elements with an improved temperature sensor configuration) that seals the fluid within the one or more chambers in order to form the inflated article (e.g., inflated packaging material). In particular, the sealing apparatus provides improved sealing through the improved accuracy of the temperature reading in the heating zone, in part, by locating a sensor between a heating element and a protective member that covers the sensor.

A mould comprises a mould body (1) for forming therearound a body (60) with a body cavity which is accessible via an opening. The mould body is assembled from a set of mutually cohesive body parts (30,40). The body parts (30,40) are mutually releasable and removable from the body via the opening. An inflatable body (60) can be manufactured with the mould. The inflatable body (60) comprises a wall of elastomer material, which wall at least in an inflated state of the body bounds a body cavity accessible through a wall opening. The body is inflatable by filling the body cavity with a fluid.

A method for the production of a bladder accumulator (10) that separates two media chambers (16, 18) from one another in a storage housing (12) by a bladder body (14). The following production steps include extruding a plastic tube over the bladder body (14), shaping the plastic tube with the integrated bladder body (14) in a molding tool that corresponds to a predeterminable plastic core container (20), and winding at least one plastic fiber from the outside on the plastic core container (20) for the purpose of creating the storage housing (12).

An additional chamber to watercraft that adds both volume and curvature to other compartments or components of the watercraft that are essentially flat is described. The additional chamber provides for modular construction of watercraft for creating volumetric space as well as a curved surface to the outer portion of the watercraft. The chamber advantageously increases the aesthetic appeal of the watercraft as well as provides a surface on which water is discouraged from pooling or collecting on. Various watercrafts having such a chamber are also described.

An internal tensioning structure for use in an inflatable product fulfills the basic function of maintaining two adjacent inflatable surfaces in a desired geometric arrangement when the inflatable product is pressurized. The tensioning structure is formed by connecting a pair of plastic strips sheets via spaced-apart strands, such as strings or wires. When pulled taut, the strands provide a high tensile strength between the two opposed plastic strips. At the same time, the plastic strips facilitate a strong, long-lasting weld between the tensioning structure and the inflatable product.

A mold comprises a mold body (1) for forming therearound a body (60) with a body cavity which is accessible via an opening. The mold body is assembled from a set of mutually cohesive body parts (30,40). The body parts (30,40) are mutually releasable and removable from the body via the opening. An inflatable body (60) can be manufactured with the mold. The inflatable body (60) comprises a wall of elastomer material, which wall at least in an inflated state of the body bounds a body cavity accessible through a wall opening. The body is inflatable by filling the body cavity with a fluid.

The present disclosure is directed to a web inflation and sealing apparatus. The device may include a support member for holding a supply of web material and sealing apparatus may include an inflation and a sealing assembly operable to inflate the web material with a fluid by directing the fluid between superimposed plies of the web material and to seal the plies together to seal the fluid therein. The apparatus may include a guide member positioned between the support member and the inflation and sealing assembly such that when the web material is routed from the supply toward the inflation and sealing assembly via the guide member the web material follows a curved longitudinal path. The guide member may define a web-supporting surface extending transversely to the longitudinal path with an elevated profile portion defining at least a portion of the web-supporting surface.
