Definitions

  • the invention relates to a dispensing head for a containing a pasty substance Pressure pack according to the preamble of claim 1.
  • pasty media such as toothpaste, shoe polish, gels for cosmetics or the like to be packed in pressure packs.
  • pressure packs often have pressure vessels in which bags are arranged on the inside are which contain the pasty substance while between the container and bag a print medium is filled. If the dispensing valve is operated, the one at the top Arranged end of the container, the pasty medium is discharged and reaches a dispensing head via a channel. Can happen that pasty substance continues to escape after the dispensing valve is closed, for example by heating the material or the like. This appearance is disadvantageous, especially if such packs in luggage or otherwise in Bags or the like are carried.
  • the invention has for its object a dispensing head for a pasty To create substance-containing pressure pack, with which in a simple manner and with simple means a follow-up of the substance after the closure of the Dispensing valve is prevented.
  • valve member made of plastic, which has a valve surface, which is directed towards the dispensing valve and with a sealing edge or sealing surface in the Channel interacts.
  • a spring section is integrally formed on the valve member, which cooperates with a channel section so that a biasing force on the valve member acts in the closing direction.
  • the one-piece arrangement of valve member and Spring section is made in a two-component injection molding process, the Valve member made of an elastomer and the spring section made of harder plastic shaped, e.g. made of polyacetal. Becomes pasty by actuating the dispensing valve Substance is discharged due to the pressure with which the material emerges Valve member opened and allows the substance to escape. Once the dispense valve is closed, the valve member also closes and prevents overrun.
  • the material of the valve member has sufficient spring properties has ensured by which a return of the valve member in the closed position is.
  • the spring action should not be too high so that the Pressure loss is not too great and even when the pressure in the pack decreases discharge is still possible.
  • the channel section has a conical surface, engage on the outwardly pointing spring arms of the valve member.
  • the spring arms When opening of the valve member, the spring arms are deformed and generate a restoring force to reset the valve element as soon as the opening pressure is no longer present.
  • valve member on the piston section the valve member has a conical valve surface and the piston section is connected to a shaft on which the spring section, preferably the spring arms are molded.
  • spring arms are molded.
  • two are diametrically opposed Spring arms provided.
  • the sealing edge or the surface and the channel section is formed in a plastic sleeve which in the end section of the channel is pressed.
  • Valve element and sleeve can be prefabricated as a unit which is then inserted into the channel.
  • a conventional plastic made of polypropylene or polyethylene can be used for the sleeve be used.
  • a polyacetal is preferably used for the valve member used, which has more favorable spring properties than the above plastics.
  • the single figure shows a section through a dispensing head according to the invention.
  • a dispensing head 10 which is shaped like a hat, with a approximately central shaft 12 which fits into a valve piston 14 of a dispensing valve 16 is plugged in.
  • the dispensing valve 16 has a valve housing 18 that communicates stands with the inside of a pressure vessel, not shown in detail or the part of the container that contains pasty medium under pressure.
  • a Spring 20 presses the valve piston 14 against a sealing washer 22 which is in the dome 24 a cap-shaped cover 26 is arranged and on the top of the Valve housing 18 rests.
  • the lid 26 is made in a suitable and known manner placed on top of a container and connected to it. It is not required to provide details. Housing 18 and seal 22 are held together by suitable deformation of the dome 24.
  • the shaft 12 has at the lower end a recess 28 through which the medium into a channel 30th can occur in the shaft 12 when the piston 14 is lifted from the seal 22 Has. This is done by pressing down on the dispensing head 10.
  • the vertical channel 30 has a channel section 32 running transversely thereto Head 10 connected, which has an enlarged portion 34 toward the opening.
  • a sleeve 36 is pressed into this channel section 34. It consists e.g. out Polyethylene or polypropylene.
  • the sleeve has a first cylindrical bore section 38, which is followed by a conical surface 40.
  • the conical surface 40 which acts as a sealing surface, tapers away from the bore section 38.
  • To the Sealing surface 40 is followed by a conical surface 42, which extends from the bore section 38 further expanded.
  • a cylindrical part adjoins the conical section 42 Section 44 of the channel section 32.
  • a valve member 46 is seated in the sleeve 36. It has a piston section 48 which has a conical valve surface 50 on its rear side. The diameter of the Piston section is slightly smaller than the bore section 38, so that Valve member 46 is guided accordingly.
  • the valve surface 50 is closed in Diameter of smaller shaft section 52, at the rear end of two diametrically arranged spring arms 54 are formed, which extend radially outwards extend and are bent on the outside at 56, creating an outer Rounding results.
  • the bent portions 56 act with the conical Section 42 together.
  • the piston section is molded from an elastomer Shaft section 52 and spring arms are made of polyacetal. The production takes place in known two-component spraying process.
  • valve member 56 is first pre-assembled in the sleeve 36.
  • the Piston section 48 pressed slightly over the edge, which through the two surfaces 40. 42 is formed.
  • the spring arms 54 become a little to the right and radial deformed inward and thereby create a preload on the piston section 48, so that the valve surface 50 seals against the sealing surface 40 against the system reached.
  • valve member 46 opens due to the pressure, so that the substance can easily escape through the bore 46.
  • the valve member returns 46 due to the spring action of the arms 54 in that shown in the drawing Position back and prevents the pasty material from running on.
