Definitions

  • the present disclosure relates to novel and advantageous liner retainers for liner-based storage and dispensing systems. More particularly, the present disclosure relates to a liner retainer that has features for minimizing the risk of damage occurring to the liner during insertion in, or removal of, the liner with respect to an overpack and/or placement, adjustment, or removal of the retainer with respect to the liner. Even more particularly, the liner retainer of the present disclosure in some embodiments includes curved edges forming a generally pie-shaped region or cut-out in the resting rim of the retainer that prevents or limits damage to the liner.
  • Container systems may be used in many industries for storing, shipping and/or dispensing materials of any viscosity.
  • numerous manufacturing processes require the use of ultrapure liquids, such as acids, solvents, bases, photoresists, slurries, cleaning formulations, dopants, inorganic, organic, metalorganic and biological solutions, pharmaceuticals, and radioactive chemicals.
  • ultrapure liquids such as acids, solvents, bases, photoresists, slurries, cleaning formulations, dopants, inorganic, organic, metalorganic and biological solutions, pharmaceuticals, and radioactive chemicals.
  • Such applications require that the number and size of particles in the ultrapure liquids be minimized.
  • semiconductor manufacturers have established strict particle concentration specifications for process chemicals and chemical-handling equipment. Such specifications are needed because, should the liquids used during the manufacturing process contain high levels of particles or bubbles, the particles or bubbles may be deposited on solid surfaces of the silicon. This can, in turn, lead to product failure and reduced quality and reliability.
  • a shipping and dispensing system will include a container of some kind, and/or a liner, a cap that may be used to seal and protect the contents of the storage system when the contents are not being dispensed, and a connector that may be used to dispense the contents from the container.
  • one or more retaining elements may be used to help correctly orient a liner in an overpack and/or hold a liner in a stable position in an overpack, for example.
  • Some known retainers are generally cylindrical in shape and are configured to open at a hinge point, in a clam shell fashion, such that the retainer can be positioned around the fitment or neck of a liner, for example.
  • the retainer may be closed around the neck of a liner.
  • the walls of the liner may be caught between the two closing ends of the retainer, which can result in damage to the liner, including causing rips or tears in, or weakening of the walls of a liner.
  • the contents of a liner may include fluids, powder, etc. that may substantially lose or entirely lose their value if they are contaminated with ambient air, which may result in a loss of valuable material, time, money, and/or vendor/customer goodwill. Accordingly, for many applications it is important and/or critical that contaminants are kept out of the contents stored in a liner.
  • the present disclosure in one embodiment, relates to a liner-based assembly including an overpack having a mouth, a liner disposed within the overpack, the liner including a liner neck, and a retainer ring removably securable about the liner neck for securing the liner at the mouth of the overpack.
  • the retainer ring may include a first half portion and a second half portion, joined at one end thereof by a hinge permitting the other ends thereof to open and close in a clam-shell manner about the hinge to removably secure to the liner neck.

  • the bottom corners 316 of the lower cylindrical ring 304 may comprise any suitable radius configured to provide softened edges at the bottom of the receiving slot 314 and provide an opening 318 large enough to permit the liner wall to slip out of the receiving slot without pinching, which in many embodiments may depend on the thickness of the liner.
  • the bottom of the opening 318 may have a width, wl, that is twice, three times, quaudruple, or more the width, w2, of the receiving slot not adjacent the curved bottom corners 316.
  • the curved bottom comers reduce or eliminate the effects of any small tight space existing between the two halve portions 102 and 104 at the closure ends 108 adjacent the receiving slot that may otherwise easily trap and/or damage the walls of a liner.
