Definitions

  • the invention relates to a plastic container according to the Preamble of claim 1.
  • Such containers are in a variety of designs known that serve degassing, liquid filling material to store liquid-tight and the resulting Gas volume via a degassing device To let the lock escape to the outside. Without one such a device would result in the container itself bulging more and more increasing gas pressure or even bursting.
  • peroxide solutions that contain additional active additives, there is an increased Elimination of gas - mainly oxygen - and therefore one larger gas volume per unit of time, which over the Degassing device must be derived.
  • This Furniture is ideally gas permeable only, not but for liquid.
  • the (arranged in the lock gas permeable membrane) device by wetting with the filling material (by shaking) is out of function what a Bursting of the container.
  • Such Degassing device is for example by obvious Prior use known. Also falling over of the container critical, because then by wetting the gas-permeable Membrane the device is disabled and This can cause the container to burst.
  • the invention has for its object a generic To create containers that are independent of its Location of the functionality of the degassing device is not restricted and which is inexpensive to manufacture.
  • the generic container as a degassing device at least partially at least in the jacket area is provided with such a container wall thickness and consists of such a gas-permeable material that the container has the same or greater gas permeability per unit of time than that by the Degassing of the filling gas volume per Unit of time is achieved that regardless of the location of the Container functionality of the degassing device is not restricted, and that the container by Internal pressure does not bulge undesirably, being for a better stability of the container the container wall thickness in Shoulder and floor area is more developed than in Coat area and the shoulder and bottom area against Bulges is rigid. Besides, is the container is inexpensive to manufacture.
  • the preferred mono material is Ethylene vinyl acetate copolymer or its polymer mixture with polyethylene or lower density polyethylene or Polypropylene or polycarbonate or their copolymers or their mixtures (polyblends).
  • the container is designed to be crushable.
  • the relatively thin container wall is used to increase stability in the jacket area with a stiffening profile Mistake.
  • the container wall stiffening profile can the container wall at least in Jacket area with an outer cardboard stiffener - optional releasable - provided.
  • An oxygen-releasing material is suitable as filling material Liquid or a peroxide solution such as that is usually used in hairdressing.
  • the invention is based on two exemplary embodiments explained in more detail.
  • the plastic container 1 shown in Figure 1 for degassing, liquid filling material consists of monomaterial and is provided for a liquid-tight closure 2.
  • a degassing device 3 is at least partially in the Shell area 4 such a container wall thickness 5 and such gas permeable material 6 provided that the Container 1 has the same or greater gas permeability per unit of time than that by the Degassing of the filling gas volume per Time unit.
  • Stiffening grooves 7 are in the jacket area 4 arranged that the relatively thin-walled jacket region 4th reinforce, which results in better handling.
  • the jacket area 4 is provided with a cardboard stiffener 8 which, of course, the leakage of gas through the Jacket area 4 must not hinder, for example by a corresponding perforation.
  • the cardboard stiffener 8 detachably formed from the container 1 be (due to separate disposal).
  • the cardboard stiffener 8 can also be provided as a label.
  • the example of a 1000 ml container 1 according to FIG. 1 is a height of 260 mm and a diameter of 84 mm intended.
  • PP or LDPE is preferably used as the material a container wall thickness 5 of 0.45 mm or 0.5 mm provided, with an application weight of 40 g or 50 g results.
  • a corresponding container according to the state of the Technology usually consists of HDPE and has one Container wall thickness of 0.6 mm with an insert mass of 63 g.
  • a degassing device 3 and a significantly lower stake cost reduction through Material minimization and elimination of a separate one Degassing valve and possibly lower Environmental impact).
  • the table below shows the respective oxygen permeation for different materials and container wall thicknesses, container A representing the prior art and containers B, C, D representing examples according to the invention.
  • a comparison of containers B and C shows that PP a container wall thinning (from 0.5 mm to 0.45 mm) gives greater oxygen permeability, as does one still gas permeable material such as LDPE (container D).
  • LDPE container D
  • a second embodiment of a container 1.1 is in shown in Figure 2.
  • the container 1.1 consists of foamed material 9, e.g. B. PP, and has as a degassing device 3.1 a correspondingly thicker, foamed Container wall thickness 5, which despite a small Insert mass a higher stability and a higher Gas permeability of the container 1.1 results.
  • This Container 1.1 can be produced in the extrusion blow molding process become.
