Definitions

  • the subject-matter of the invention is the method of manufacturing of a container characterized in a high resistance to damaging effects of pressure produced by the medium, accumulated in its inside and the container itsel, manufactured in accordance with method described in this invention, to be especially applied for storage of liquids and gases under high pressures.
  • This method enables placement of additional stiffeners in the inside of the product, which are especially required in case of squeezed (crushed) containers.
  • torn containers by means of the medium in its inside
  • much more efficient are containers manufactured as a whole, in one element. In this case forces tangent to the walls of the container, while acting outwards - unseal the container in these points where elements of the form have been joined.
  • a relatively simple solution is placing the described container in another, more resistant, container. This may be accomplished in a way, described in the patent application No P-312662 i.e. by placing a plastic container in the inside of a steel basket, which braids the outside planes of the container. Nevertheless, it should be underlined that the application of metals considerably increases weight of the final product and, at the same time, reduces weight of the medium that can be contained in such container.
  • Such reinforcement can also be made by means of lamination, the method consisting in placement of an additional layer of fibres on a surface of the product, which are wrapped and joined with the product surface with resin.
  • This method of increasing strength of construction has been presented as an example e.g. in the patent No PL 168196.
  • the method to reinforce construction of the container operating under high pressures, acting on its walls out of its inside is also known, and it has been disclosed in the Polish patent No 184943.
  • the container is wrapped with fibres (snarls), which are arranged on the container surface in a way resulting in increase of its resistance to stresses.
  • the Polish patent No PL -197773 the method of manufacturing of a plastic container operating under high pressure, has been disclosed. This method consists in strengthening of the container construction by lamination of its walls. In the course of lamination, in the point of connection hole/holes, flanged inserts are placed which are provided with at least two gaskets. They ensure resistance of the container to changeable thermal and mechanical conditions during its exploitation.
  • the method according to the American patent application No US 20050167433 is also known, which consists in covering a perform manufactured by means of blow moulding, with the additional coating, being tightened around the internal container. It is also possible to perform lamination with separate fibres - threads padded and entangled on the surface of the container. As it has been disclosed in the document No US20050077643, bobbins packed with fibres turn around the moving container, forming a net with a pattern adjusted to the working conditions of the final product.
  • joint connection pipes are also fixed. Taking into consideration pressure ranges within which such a connection should operate, joint connection pipes are made of metal resistant to further treatment, especially under high temperatures. Additionally, in the area of metal/plastic connection, the gaskets (PL- 197773) are placed, which on the successive stage of treatment and lamination are being pressed to individual layers of the product to ensure tightness of this connection. It is exceptionally important that a free edge of the joint connection pipe preserves its ideal form during lamination and heat treatment and is not submitted to any deformations that can result in deterioration of the final product tightness.
  • the method of manufacturing of the container which consists in uniform manufacturing of the container and joint connection pipe (as one element).
  • the perform received on the first stage of production is being placed in the cooled cavity and then - blow moulded to obtain working dimensions. After this operation, the container is finished by means of lamination.
  • the method of manufacturing of high-pressure container in accordance with the invention enables production of the container resistant to effects of significant bursting forces acting in the container, the outer surface of which is reinforced by means of lamination and which, along with a sealing ring placed in the joint connection pipe, protects the containers against bursting in case of increase of internal pressure and against mechanical damages from outside.
  • the method according to the invention in the first stage includes manufacturing of a component being a preform of the future container, with the application of any known technique of preforms making.
  • the received preform is then blow moulded to obtain the required size and shape.
  • Such preform is made of thermoplastic material, preferably PET material.
  • thermoplastic properties of the material enable repeatable plasticization and solidification of the material.
  • conditions in the entire volume of the material injected into the form are homogenous.
  • the second component used to produce the container in accordance with the invention is the joint connection pipe made of the material selected from among ferrous metals, non-ferrous metals or composites.
  • joint connection pipe On the lower surface of the joint connection pipe, grooves radiate around the hole of the joint connection pipe, from which at least one is provided with O-ring type seal, whereas the second groove situated in the close vicinity to it - is provided with a sealing ring.
  • the joint connection pipe is preferably provided with the additional joggle in a form of a ring situated around the joint connection pipe hole. Also preferably, that in the outer surface of the joint connection pipe (in relation to the container inside), there is at least one blind hole. During the container lamination, into such hole/holes the resin used in the production process is flowing in.
