Definitions

  • Non-return valve system for products which can be filled with air
  • the present invention relates to a non-return valve system for inflatable products, comprising elements 1 executed from soft plastic or rubber film material which provide a non-return valve function when the product is inflated.
  • a first object of the present invention is to make available a non-return valve system for inflatable products, which offers production engineering advantages with lower and more competitive prices, and also to increase the quality of all the finished inflated products through the simpler and more reliable non-return valve system that is made available.
  • the non-return valve system is made available in one and the same operation in production and in the joining together of inflatable products, and improved quality of the inflatable products is thus achieved more simply and at lower cost.
  • the invention thus relates to an arrangement for the more rational production of, for example, inflatable mattresses, thereby obtaining a multi-function effect in a single operation.
  • Fig. 1 shows a partially sectioned view of a non-return valve in accordance with the invention, executed on an inflatable mattress.
  • the non-return- valve element 1 exhibits an angled shape 2 forming an lug 8 with a flap 3, which seals and provides the non-return valve function in the event of overpressure occurring inside the inflated air-containing product 4 and is executed in one and the same operation as the product 4 is joined together. Illustrated in Fig. 1 is the non-return valve element, which, through its angled shape 2, seals and provides the non-return valve function in the event of overpressure occurring inside the inflated air-containing mattress 4, etc.
  • the non-return valve 2, 7 is executed in one and the same operation in conjunction with the joining together 5 of, for example, the inflatable mattress 4.
  • the material in the inflated products 4 must preferably be a soft film 6 of plastic or rubber, which also embodies the non ⁇ return valve 2, 7.
  • the non-return valve 2, 3, 7 is opened in the event of it becoming necessary to empty the air 10. Pulling on the lug 8 causes the flap 3, which had sealed the valve, to disappear. It is also possible to insert a pipe 9 into the filling channel 7, so that the filling and emptying of air 10 can take place and can be controlled from a greater distance. Air 10 is emptied by pulling on the hose 9 or, as described above, by pulling the aforementioned lug 8.
  • the desired non-return valve function and the inflatable product 4 are thus obtained in a single manufacturing operation as the film 6 is joined together around the element to form a seam 5.
  • the drawing shows a compartment 11 in the mattress 4 in a position empty of air, whilst a second compartment 12 is shown inflated, and a further compartment 13 is shown as a sectioned view.
  • Forming of the element 1 takes place simultaneously in a single operation in conjunction with the joining 5 of the entire inflatable product 4.
  • the flap 3 is formed by the overpressure present in the exemplified inflatable mattress 4, and the non-return valve function and the inflatable element 1 are thus obtained in a single operation as the join 5 is produced around the element 1.
