Definitions

  • the invention relates to a container closure with an internal pressure limiter according to the preamble of claim 1.
  • Containers with an internal pressure limiter are brought into various contexts, for example in the case of plastic bottles which have a slightly gassing content, but may only be loaded with a relatively low internal pressure. If the internal pressure rises due to heating and vibrations during transport, then gas must be released.
  • An example is bottles with bleach that tends to generate gas, but the bottles should not be exposed to a significant internal overpressure.
  • a construction for pressure limitation is known, for example, from GB-A2 026 994, Fig. 4, the upper edge of the container neck serving as an annular valve seat, on which a rubber disc rests as a valve body, which acts against the spring force of a metal disc and the metal container cap Container neck can lift off, so that the developed gas can pass between the edges of the container neck and the rubber washer and can escape through a lateral slot in the cap.
  • the response limit pressure depends on the screw-on width of the container closure.
  • valve body is stamp-like and engages in a funnel-shaped valve seat, and the valve closure surface is a narrow ring surface, possibly only a ring line.
  • Containers for such liquids which are part of the daily consumer goods, are generally of little valuable commodity. Cap constructions with metal springs or even only with metal plates that have to be used make the construction more expensive. A pressure limitation with the help of the usual sealing washer, which is pushed away by the excess pressure from the neck of the container and opens a path through the thread, on the other hand can hardly be set to a precise response pressure and is only suitable for relieving higher pressures.
  • the invention has for its object to provide an extremely easy to produce container closure with internal pressure limiter that is responsive even at low internal pressure.
  • the sponge body provided with the film and acting as a valve spring assembly can be produced as continuous goods from which the parts required for the individual container closure are punched out.
  • the insertion of the individual sponge parts provided with the film is very simple, the spring body on the one hand and the valve body on the other hand need not be installed separately.
  • the container closures can thus be produced in inexpensive series production, the construction according to claims 2 and 3 being particularly suitable.
  • the entire structure is particularly suitable for limiting internal gas pressure, since the escaping gas can easily seep through the compressed sponge body, while a liquid that may also be contained in the container is largely retained.
  • the construction according to claims 8 and 9 is particularly expedient and easy to build.
  • the measure according to claim 10 replaces the normally one valve opening with a plurality of valve openings, as a result of which the passage area can be enlarged without the sponge body provided with the film bulging out.
  • a plastic closure cap (3) which is attached to the container neck with a screw or a bayonet catch (4). 1) is attached.
  • the sealing cap is connected to a guarantee ring (6) which is attached to the container neck and remains there via webs (5) which, as tearing webs, indicate the original filling of the container.
  • the container to which the container closure shown belongs is a plastic bottle for holding a laundry bleach. Such agents tend to develop gas, which could lead to inflation of the plastic bottle.
  • the closure cap (3) is therefore equipped with an internal pressure relief valve (11).
  • there is a degassing opening (12) in the top of the cap that is to say in its radial top surface, which leads outward from the inside of the cap.
  • the area in which the opening (12) is located - eccentrically in the example shown - is surrounded by an annular flange (13) projecting from the cap top wall to the container and onto which a cover cap (14) is attached.
  • This has an essentially cylindrical plug-in part in the form of two ring flanges (15), (16), between which the ring flange (3) can be inserted.
  • a sponge body (25) is inserted, which is laminated on its underside with a polyethylene film (26) that has a circular circumference (27).
  • the polyethylene film (26) covers the entire inner floor surface (19) and the hole (18).
  • the sponge body is shown in a relaxed state in FIG. 2, while the sectional drawing of FIG. 1 shows it compressed.
  • the sponge body is shortened to 1/5 of its original length by the compression. This considerable compression causes the film (26) to be pressed onto the surface (19) with significant force. It creates a seal there which is sufficient for moderate pressures, including the pressure which the weight of the container contents exerts in the event of the container tipping over.
  • the sponge part of the sponge body (25) consists of a material of sufficient porosity to allow the gas to be seeped out to be discharged from the container.
  • the passage of liquid is much slower, and the penetration of foreign bodies and foreign materials into the space of the valve (11) is prevented by the sponge body (25).
  • Polyamide is also suitable as the material for the film (26).
  • polyether foam is preferred, with an average bulk density of 72 kg / m 3 , and a number of pores of 20 to 25 per cm, a compression hardness (according to ISO 3386) of 32 kPa.
  • Fig. 3 which shows only the upper part of a closure cap relates to an embodiment in which in the disc-shaped bottom (17) of the cover cap (14) instead of the one hole (18) negotiate several holes (28) are. These holes are distributed over the inner surface (19), but all maintain a minimum distance from the ring flange (16) and thus from the edge of the sponge body (25). There are several degassing openings (12) in the top wall of the cover cap (3), two such openings are visible. According to a further embodiment, not shown, the degassing openings and the holes can also each be designed as a sieve or grille.
  • Fig. 1 shows the unpressurized state
  • Fig. 3 shows the state in which an excess pressure in the container just leads to a gas escape.
  • the film (26) is first lifted away from the area (19) in the area of the holes (28), but with increasing pressure but further above the surface (19), with the circular edge of the film (26) simultaneously moving inwards from the ring flange (16) is pulled away. Finally, in bubbles or continuously, the gas passing through the holes (28) reaches this edge and gets into an annular space (30) formed between the sponge body (25) and the inner annular flange (16). From there, the gas flows through the compressed sponge body (25) to the degassing openings (12).
  • Fig. 4 shows in a partial representation corresponding to that of Fig. 3, an embodiment in which the underside of the cover (14) instead of the flat disc shape is formed by a conical bottom (32), in the top of which protrudes downwards, the hole ( 18) is located.
  • the cylindrical sponge body (25) with the polyethylene film (26) in the relaxed state according to FIG. 2 assumes a slightly “sharpened” shape here, so that the surface pressure exerted by it is higher in the area of the circumference (27) than in the vicinity of the Lochs (18).
  • the film (26) gradually rises from the inside to the outside of the surface (19) until the gas reaches the edge, and when the pressure is released, it cleanly rests against the surface from the outside.
  • FIG. 5 shows, in a representation corresponding to FIG. 4, a conical base 32 'which projects inwards.
  • the sponge body is in this case the strongest around the hole 18 and the least prestressed at the circumference. A gas pressure that can raise the film at the hole 18 is therefore suddenly discharged as a gas bubble passing between the film (26) and the surface (19).
