Definitions

  • the invention relates to a bag valve for a pressure vessel, in particular pressure cans, for dispensing viscous to pasty products, comprising a valve plate, a valve body arranged on the valve plate, a stem guided in a central recess of the valve body with at least one inlet opening for the product contained in the bag that can be opened by actuating the stem, at least one outlet opening, an elastic element acting on the stem, sealing elements acting between the valve plate and valve body and between the valve body and stem, and a bag arranged on the valve for the product to be dispensed through the valve.
  • the bag is secured to a holding element having a central passage, the holding element having a laterally extending holding plate that is sealingly connected to a collar of the valve body that extends vertically on the can side.
  • a pressure can equipped with such a bag valve The invention further relates to a pressure can with such a bag valve.
  • Pressurised cans for dispensing viscous to pasty substances have been known and in use for a long time. They are used, for example, in the food sector (cake decorations), in hygiene products (toothpaste) and in cosmetics. Piston cans are often used for this purpose.
  • a piston divides the pressurised can into an upper and a lower part. The upper part, below the valve, contains the product to be dispensed and the lower part, below the piston and above the base, contains a propellant.
  • the often inadequate separation of product and propellant is problematic, and the introduction of both the product and the propellant is complex.
  • a second valve in the base of the can is required to fill the propellant. The second valve and the piston, as well as the filling equipment, make the cans and the product considerably more expensive.
  • bag cans contain the product separately from the propellant gas. Attaching the bag to the can body presents the same problems with the Filling with propellant gas, as with the piston can described above.
  • the product When the pouch is positioned at the valve, the product must be filled through the valve, which is time-consuming and laborious, and also contaminates the valve. Due to the design of the valve systems, the filling speed is limited.
  • the introduction of the propellant gas requires either a special design of the main valve or a second valve in the base of the can.
  • Such pouch cans are not suitable for products with a viscosity of more than 50 Pas. They are used, for example, for shaving gels.
  • Bag valves of the type mentioned above are made of US 2010/320 230 A1 , US 2010/001020 A1 , EP 2 634 111 A1 , EP 0 471 503 A2 and JP 563 281 977 A known.
  • the object of the invention is therefore to provide a pressurized container with which viscous and pasty substances stored in a bag can be dispensed using a propellant.
  • a bag container should be inexpensive to manufacture, easy to fill, and safe to handle.
  • the bag valve according to the invention is derived from a conventional solid valve for the application of polyurethane-based assembly foams, as used, for example, in EP 2 028 131 A1 and EP 3 044 123 A1 described.
  • a coil spring can be used.
  • a combination of a coil spring and a thermoplastic elastomer is also particularly suitable.
  • a retaining ring made of a durable plastic, such as polyoxymethylene, serves as a support for the elastic element at the valve-side end of the stem.
  • FIG. 1 shows a bag valve according to the invention without a bag installed.
  • the actual valve is designated by the reference numeral 1, the holding element for the bag by 2.
  • the valve 1 consists of the valve plate 3 with the crimped edge 4, the stem 5, the valve body 6 with a downwardly drawn collar 7, which is aligned with the can side, and the elastic element 8, in this case a sleeve made of a thermoplastic elastomer arranged around the stem 5.
  • the stem 5 has several inlet openings 9 at its can-side end 2 and an outlet opening 10 at the valve-side end. In the area of the outlet opening 10 there is a plastic sleeve 11, which serves as an upper abutment for the elastic element 8.
  • the lower or can-side end of the elastic element 8 is supported in an annular groove in the valve body 6.
  • the retaining element 2 consists of a retaining pin 21 and a retaining plate 22, which are arranged concentrically around a passage 23.
  • the retaining plate 22 extends laterally toward the edge of a surrounding pressure chamber and is connected to the collar 7 of the valve body 6 via a sealing ring 24 and locking elements 25 (see detail X).
  • the retaining pin 21 itself can have any shape, but is preferably designed in a diamond-shaped, elongated manner, roughly resembling a ship's shape. It has circumferential ribs 26 that serve to better hold a mounted bag.
  • the bag valve according to the invention is actuated to remove the bag contents by pressing the stem 5 using a standard adapter. After removal is complete, the elastic element 8 ensures that the valve returns to the closed position. The valve can be actuated again until the bag contents have been completely removed.
  • the plate 22 has a receptacle 27 for an O-ring, notches 25 arranged around the circumference for securing the retaining element to the collar 7 of the valve body 6, and an inner upstanding edge 29 that extends on the valve side and improves the fit of the retaining element on the collar 7 of the valve plate 6.
