Thermoforming film container plus tube - by mould tools which grip tube in tapered holes so that when vacuum thermoforming is completed some space allows film to cool round tube

A flexible thin-walled container with at least one film filling or emptying tube for liq. contents is produced by making the container from two adjacent extruded flat sheets of thermoplastic material, thermoforming them under vacuum, and welding them together when closing the thermoforming mould. Before the mould is closed the tube is positioned between the two flat sheets so that, when the mould is closed, the sheets are not only welded together round their edges but are also welded to the tube; the outer end of the tube remains free so that the thermoplastic material/film round it can be cooled in shape. ADVANTAGE - The filling/emptying tube is virtually positioned and welded at the same time as the two halves of the container and in the split line concerned. The method ensures that the film round the tube cools effectively before the mould is opened again, so that it does not adhere to the tube or to the mould.

Sports Ball with Integral Ball Casing and Bladder Body

A sports ball includes a barebone ball and an outer ball layer. The barebone ball includes an inflatable bladder body and a ball casing. The ball casing, which is formed in an integrated structure, has an outer circumferential surface, an inner circumferential surface to define an interior cavity to fittingly enclose the bladder body therein, and a plurality of pre-formed channels integrally and indently formed on the outer circumferential surface, such that the ball casing and the bladder body enclosed therewithin form a one piece integrated semi-product of the sports ball. The outer ball layer comprising a plurality of outer cover panels overlapping on the outer circumferential surface of the ball casing at a position that edges of each of the outer cover panels are aligned with the corresponding pre-formed channels respectively. 1. A method of manufacturing a sports ball , comprising the steps of:(a) providing an inflatable bladder body and a ball casing having a shape corresponding to said bladder body after being inflated;(b) placing said bladder body and said ball casing in a casing mold at a position that said bladder body is enclosed within said ball casing;(c) vulcanizing said ball casing with heat to integrally bond said ball bladder with said ball casing to form a one piece integrated barebone ball as a semi-product of said sports ball, wherein a plurality of pre-formed channels are integrally and indently formed on an outer circumferential surface of said ball casing; and(d) overlappedly attaching a plurality of outer cover panels on said outer circumferential surface of said ball casing at a position that edges of each of said outer cover panels are aligned with said corresponding pre-formed channels respectively to form an outer ball layer to enclose said ball casing.2. The method claim 1 , as recited in claim 1 , wherein the step (b) further comprises a step of aligning two or more casing panels edge-to-edge to form said ball casing such that said ...

ULTRASONIC WELDING MEMBER AND ULTRASONIC WELDING METHOD

Disclosed are: an ultrasonic welding member which is independent of a first member and a second member and which is held between a surface to be welded of the first member and a surface to be welded of the second member prior to ultrasonic welding between the surface to be welded of the first member and the surface to be welded of the second member having a shape parallel to or fitted into the surface to be welded of the first member, the ultrasonic welding member characterized by including a thermoplastic resin and satisfying a discontinuous forming requirement, an outside opening requirement, and a bonding place reduction requirement; and an ultrasonic welding method using the ultrasonic welding member. The ultrasonic welding member may include a plurality of streaks at least in a part thereof. The ultrasonic welding member may be a substantially lattice-shaped fabric or textile mesh at least in a part thereof. When the ultrasonic welding member is held between the surface to be welded of the first member and the surface to be welded of the second member, crossing parts of threads of the mesh may form a bonding place between the ultrasonic welding member and the surface to be welded of the first member and a bonding place between the ultrasonic welding member and the surface to be welded of the second member. 1. An ultrasonic welding member which is independent of a first member and a second member and which is held between a surface to be welded of the first member including a thermoplastic resin and a surface to be welded of the second member including a thermoplastic resin and having a shape parallel to or fitted into the surface to be welded of the first member prior to ultrasonic welding between the surface to be welded of the first member and the surface to be welded of the second member ,the ultrasonic welding member including a thermoplastic resin, andthe ultrasonic welding member being configured such that:when the ultrasonic welding member is held ...
