Definitions

  • the invention relates to a container for dispensing particularly flammable liquids, which consists of flexible, compressible container walls, a safety closure and a cover cap.
  • Such containers are known for example as dispensers or dosing bottles for oil, petrol or household spirit, as spray containers for solvents and the like in various designs. They usually consist of a flexible plastic that is resistant to attacks by the intended container content, which allows the container to be compressed by hand by pressing in its walls.
  • the contents of the container are emptied through a correspondingly provided opening.
  • the opening is closed by a cover cap which sits in a sealing manner and prevents evaporation of the contents and prevents the container from leaking in the event of accidental pressure, impact or falling.
  • a certain degree of safety when handling easily flammable liquids is achieved in known containers by arranging the smallest possible, for example nozzle-like, outlet opening. To dispense, the liquid is pressed through the nozzle with pressure. The overpressure generated in the container prevents air from penetrating into the container for the duration of the removal process, so that a flammable liquid-air mixture only forms behind the outlet opening. If a jet of a highly flammable liquid is directed into an open fire from such a container, this liquid jet can ignite itself, but a retraction of the flame through the narrow nozzle opening into the interior of the container is not very likely during the emptying process.
  • a reversal of the situation occurs when the removal of liquid is to be stopped and the pressure on the container wall is relieved.
  • the elastic container walls snap back, a negative pressure develops in the interior of the container, which is caused by the inflow of air or an inflammable air-gas gas formed by the evaporation of liquid. Mixture is balanced. In the worst case, the flame may strike the inside of the container and cause an explosion.
  • the object of the invention is to provide a container of the type mentioned, which allows the liquid to be emptied into an open flame or onto a heated surface without the risk of the flame striking back into the interior of the container and from the, if desired, a precisely metered amount of liquid can be dispensed.
  • a container of the type mentioned in the introduction that a membrane-controlled cone valve which can be actuated by reducing the interior of the container is provided as a safety closure, in which the membrane has a central recess delimited by a sealing edge through which a valve cone is inserted on which the sealing edge rests.
  • valve plug of the plug valve In order to balance the pressure inside the container, the valve plug of the plug valve is pushed slightly inwards, whereby the membrane is released from the sealing seat. This creates a passage between the valve cone and the diaphragm through which air enters until pressure equalization occurs. Since this process is carried out by manual pressure on the valve cone tip, the container is located at a safe distance from an open flame, so that a kickback and thus an unwanted ignition is practically impossible.
  • the safety closure according to the invention combines the functions of a check valve which can be acted upon from the inside of the container with those of a manually operated ventilation valve.
  • the approach 4 serves as a holder and guide for the safety closure designed as a cone valve 7 and for a cover cap 8.
  • a detent 9 encircling the approach 4, preferably with a rounded surface formed, which engages in a correspondingly designed groove 10 on the cover cap 8 in a form-fitting manner.
  • the cover cap 8 can be placed on the heel 4 by means of this screw guide and can be locked with a rotary movement.
  • the outside of the extension step 6 facing the outlet is designed as a carrier for one or more snap noses 11 encompassing the extension 4 in a ring shape.
  • a cylindrical membrane carrier 12 is pushed onto these snap noses 11 from the outlet side, the inner wall of which has annular recesses into which the snap noses 11 engage in a form-fitting and sealing manner.
  • the push-on depth of the membrane carrier 12 is limited by a step 14, which is recessed in a ring in the cylindrical wall 13 of this membrane carrier and lies flush on the upper edge 15 of the extension 4.
  • the valve cone 20 is elastically resilient in the axial direction.
  • a cylindrical shaped piece 21 serves as a holder and support for the valve cone 20, its edge 22 facing away from the outlet on the upper edge 15 of the container 1 rests and radial carrier 23 are drawn inwards from its upper edge.
  • the wall 13 of the membrane carrier 12 forms a housing in which the fitting 21 is inserted with a snug fit.
  • the shaped piece 21 is fixed in its position on the container by the membrane support 12 placed on it as a cap.
  • two mutually opposite indentations 3 directed into the interior of the container are preferably formed, which mark a point which is particularly suitable for pressure on the container wall 2 for the removal of liquid.
  • the size of each indentation 3 permits the intervention of at least one fingertip. If the container wall 2 is compressed at the indentations 3, the internal volume of the container is reduced by a certain amount, which is determined by the relative distance between the container walls and by a stop position in which the loading touch container walls in the recess 3 on the inside, is limited.
  • indentations a plurality of indentations, which practically have different output volumes, or pairs of such indentations, can be provided on the container 1.
  • pressure can also be exerted on any other part of the container wall 2 and liquid can be dispensed in the process.
  • the sleeve 19 seals against the valve cone 20, closes the annular gap without delay and thus prevents the inflow of a possibly inflammable gas-air mixture in the container.
  • the negative pressure that arises when the manual pressure on the wall 2 in the interior of the container is relieved is not automatically, but only compensated for by manually venting the container.
  • the valve cone 20 at its protruding beyond the sleeve 19 tip 26 axially pressed against the spring force of the carrier 23.
  • the membrane 16 seated sealingly on the valve cone 20 meets the pins 24, which limit the axial co-movement of the membrane 16, lift the sleeve 19 from the valve cone 20 and thereby aerate the container 1. After ventilation, which is achieved by a short pressure on the tip 26 of the valve cone 20, this springs back into its sealing position thanks to the elastic carrier 23.
  • the described function of the safety closure therefore separates the process of dispensing liquid.
  • the container 1 in the chronological order of that of the pressure equalization and thus effectively prevents hot flame gases from being drawn into an explosive gas-air mixture.
  • an easily flammable liquid can be sprayed into an open fire without hesitation.
  • indentations 3 in the container wall 2 also prevents overdosing of the dispensed liquid.
