Definitions

  • the invention relates to a chemical bottle for pressure building products.
  • Chemical bottle are a high stability during the filling process and during storage, a high pressure resistance, to pressure-building chemicals such as ammonia, low-boiling solvents or acids reliably and safely over a longer period
  • a manufacturing process should be used for the manufacture of the chemical bottle, which allows the use of suitable for a chemical bottle materials such as polyolefins and at the same time can be carried out inexpensively and reliably.
  • a large gripping area formed integrally on the bottle is particularly favorable with a hollow gripping piece connected on both sides with the interior of the chemical bottle body.
  • the chemical bottle can be gripped and reliably handled with the whole hand of a user with a sufficiently long design of the designed for example as a handle Grj ffstucks.
  • a handle Grj ffstucks When pouring a liquid chemical from the chemical bottle, air can continuously flow into the inside of the chemical bottle through the hollow handle. In this way, a surge-free pouring of particular liquid chemicals can be reliably ensured.
  • Chemical bottle is not appropriate. Even with a slight increase in pressure inside the chemical bottle, the originally flat bottom bulges out and causes an unsteady state or tipping over of the chemical bottle.
  • Unsupported containers of uncrosslinked polymeric materials can not be permanently pressure-stable due to the rheological material properties. Only by a suitable shaping of the chemical bottle, which leads to a predefinable volume expansion and consequent deformation, a high pressure stability of the chemical bottle can be achieved over a long period. It is known that a substantially gurkugelformig designed, outwardly curved bottle bottom has an advantageous, sufficient for many applications compressive strength.
  • the shape and dimension of the individual feet can not be set arbitrarily. Regularly too large or too complex shaped feet lead to a markedly reduced wall thickness in the area of the base, so that the likewise required compressive strength and the FaIl- and the cold break-breaking strength are considerably reduced.
  • An optimized only in terms of the desired stability shaping of the base often has an unacceptable effect on the compressive strength and the fall and the cold break strength of the chemical bottle.
  • a design designed exclusively for the pressure resistance of the chemical bottle and adapted for this purpose inevitably leads to an impairment of the stability of the chemical bottle.
  • the pressure resistance and the stability of the chemical bottle can not be specified arbitrarily independently. Both the desired compressive strength and the stability the chemical bottle affect their handling.
  • blowing processes also have disadvantages with regard to the materials available and processable in these processes.
  • PET polyethylene terephthalate
  • process-related unavoidable material stresses incompatible with the practice requirements.
  • Object of the present invention is therefore to design a chemical bottle for pressure-building filling so that the chemical bottle has a high pressure resistance and high stability, safe storage and handling allows and is inexpensive to produce.
  • a chemical bottle with a substantially cylindrical false body with a handle with a hollow, on both sides in connection with the bottle body handle, with a substantially hemispherical, outwardly curved bottle bottom and with several molded in the region of the bottle bottom protruding feet , wherein the feet each have a flattened footprint.
  • the achieved by using the substantially schkugelformigen, outwardly curved bottle bottom high compressive strength is therefore not or only slightly reduced by the shape of the flattened base.
  • Through the hollow Griffstuck which is expediently arranged directly in the region of a removal opening of the chemical bottle, a simple and safe handling and surge-free removal of liquid chemicals can be ensured.
  • the flattened footprint of each stand has a flat surface of more than 1.0 cm 2 , preferably of more than 1.5 cm 2 .
  • a chemical bottle with a useful volume of about 2.5 1, for example, has a cylindrical
  • Bottle body with an outer diameter of 12.5 cm The flachrawige proportion of the flat surfaces of the base is small in relation to the entire bottom surface of such a chemical bottle, so that an undesirable deformation in the flat surfaces of the base does not need to be feared.
  • the flat surfaces of the pedestals are respectively respectively sufficiently large in order to be able to ensure high stability both during a filling process and during storage of the chemical bottle. Even if the hemispherical, outwardly curved bottle bottom should deform slightly at high internal pressure, the stability of the chemical bottle caused by the flattened base is not appreciably affected.
  • the chemical bottle has four regularly spaced pedestals. It has been shown that four feet, each with a flattened footprint are favorable in terms of stability and pressure resistance of the chemical bottle. An even number of feet can be produced even when using conventional blowing method in a simple manner that an at least three-part mold with two Formhalften and an axially movable tool bottom part is used.
  • the flattened footprints of the base are each more than 3 mm, preferably more than 5 mm below the lowest point of the substantially schkugelformigen, outwardly curved bottle bottom are arranged. Even with an exceptionally strong pressure build-up inside the base
  • a particularly high pressure resistance of the chemical bottle is advantageously achieved in that the ratio of the radius of the bottle bottom to the diameter of the bottle body is between 0.6 and 1, preferably between 0.7 and 0.8 and particularly preferably about 0.72.
  • the chemical bottle is made of a polyolefin, preferably of polyethylene (PE).
  • PE polyethylene
  • These plastic materials have advantageous properties and in particular a high resistance to most chemicals, which allow safe storage of the chemicals even over a long period of time. Also, such plastic materials can be processed with the known conventional blowing process and enable cost-effective production of high-strength chemical bottles.

  • FIG. 2 shows a further side view of the chemical bottle shown in FIG. 1,
  • FIG. 1 is a side view of a chemical bottle
  • FIG. 3 is a sectional view through a hollow handle of the chemical bottle shown in FIGS. 1 and 2 along the line III-III in Fig. 1,
  • Fig. 5 is a plan view of a foot end of the chemical bottle
  • Fig. 6 is an oblique view of the chemical bottle shown in Figs. 1-5.
  • the chemical bottle for pressure-building filling goods shown in the figures has a substantially hollow-cylindrical bottle body 1. At a head end 2 of the chemical bottle, an opening 3 for filling and emptying the chemical bottle is formed. The opening 3 has a screw thread 4 for a cap, not shown.
  • a continuous recess 5 is formed, which forms a recessed grip.
  • the dimensions of the recess 5 or of the recessed grip formed thereby are set sufficiently large to engage all the fingers of a user's hand and thereby facilitate safe gripping and handling of the chemical bottle.
  • a Griffstuck 6 is formed by a hollow handle portion, which is at its two ends in each case with thestationnkorper 1 in combination. From the sectional view in Fig. 3 it can be seen that the Griffstuck 6 has a sufficiently large diameter and rounded edges, so that larger full and thus heavy chemical bottles can be conveniently lifted, transported and handled.
  • the chemical bottle has at a bottom end 7 a substantially semicircular designed, outwardly curved bottle bottom 8.
  • a chemical cylinder with a useful volume of about 2.5 1 corresponds to the radius of the hemispherical bottle bottom 8 about 90 mm and the diameter of the hollow cylindricalarrankorpers 1 amounts to about 126 mm.
  • This ratio of the different radii of curvature has proven to be particularly advantageous with regard to the resulting pressure stability or the deformation of the chemical flask which occurs due to excessive pressurization.
  • the base 9 each have a flattened bottom surface 10.
  • the flattened bottom surface 10 is designed as a flat surface of about 1.5 cm 2 .
  • the base 9 are each rounded with continuous transitions relative to the cylindricalstationnkorper 1 and the schkugelformigen bottle bottom 8 formed. Due to the only slightly curved, continuous transitions of the base 9 of the schkugelformigen bottle bottom 8 up to the flattened footings 10 are a high
  • the flattened footprints 10 are slightly offset inwardly relative to the circumference of the bottle body 1.
  • the flattened standing surfaces 10 protrude about 5 mm beyond the lowest point of the schkugelformig designed, outwardly or down vorgewölbten bottle bottom 8 addition.
  • the number and dimensions of the individual base 9 are predetermined so that the due to the substantially schkugelformigen embodiment of the outwardly curved bottle bottom 8 achievable pressure stability of the chemical bottle is not significantly limited.
  • the chemical bottle can be produced by means of a conventional blowing method in a blow mold, whose bottom area can be pulled off the blown out chemical bottle before the chemical bottle is completely demolded. In this way, let a chemical bottle also made of a polyolefin or polyethylene and at the same time clearly at the bottom end 7 projecting base 9 form, which could not be undamaged without an extendable bottom portion undamaged from an otherwise two-piece blow mold.
  • the crimping seam 11 characteristic for the production by means of a conventional blowing process are arranged along the inner surface of the recess 5 of the recessed grip and at the bottom end 7 transversely across the bottle bottom 8, whereby the crimping seam 11 extending over the bottle bottom 8 is arranged at a distance from the shaped base feet 9. In this way, the squeezing seam 11 does not lead to an adverse effect on the pressure resistance of the finished manufactured chemical bottle.
  • a demolding of the sufficiently cooled chemical bottle from the blow mold is possible with an axially displaceable bottom area even with far protruding feet 9 in a simple manner.
