Definitions

  • the invention relates to a self-closing closure for containers intended for holding pasty or viscous masses, in particular tubes, with a closure body arranged to be elastically movable in the opening region of the container, a release being exerted against the elastic body by a pressure exerted on the material in the container against an elastic force the opening can be effected.
  • Closures of the genus shown are known. In general, these closures are formed in two parts, which makes the manufacture and / or assembly and / or operation and / or maintenance more difficult. In addition, these closures are subject to increased wear (DE 25 15 095 A1).
  • US 37 54 690 describes a closure for flexible containers, which consists of a latched cap on the neck of the container and a spring-loaded valve arranged inside the cap.
  • the valve is formed from a conical valve plate provided in the area of the material outlet opening, which is held resiliently in the cap by means of a U-shaped leaf spring.
  • the invention has for its object to provide a self-closing closure that is extremely economical to manufacture and assemble and thereby appears as a one-piece closure.
  • this object is achieved according to the invention by a transverse web attached in the opening region of the container with a reinforcing plate articulated on the longitudinal side and jointly enclosed by a soft elastic material.
  • the softer elastic material is injection molded using the two-component spray process.
  • the different properties of the two materials mean that a spring force acts on the reinforcement plate, which is caused by the tensile force of the softer material.
  • This spring force can be determined or influenced in that, according to the invention, a material accumulation is injection molded onto the underside of the reinforcement plate.
  • the material accumulation expediently runs laterally in the central region of the crossbar arranged below the reinforcement plate.
  • the reinforcement plate can be provided with openings, which expediently run in a symmetrical arrangement to the side of the crossbar.
  • the reinforcement plate has at least one anchoring rib arranged on the circumference, which can be designed as a partial circular ring and which can advantageously be fixed directly or indirectly on the container.
  • the molded, softer material can serve as a seal on the outer boundary of the reinforcement plate.
  • the reinforcement plate is connected to the crossbar via a film hinge.
  • the reinforcement plate can be molded directly onto a closure cap of the container.
  • an external pressure is applied to the wall of the container, as a result of which the outer area of the reinforcement plate is pivoted upwards in its entirety or only in the predetermined area, thereby opening up an upper opening.
  • the reinforcement plate is automatically returned to the starting position due to the spring force that can be derived from the molded softer material and the associated elasticity.
  • a bottle is partially shown as a container.
  • a closure cap 2 with an associated sealing ring 4 is arranged on the neck of this container 1.
  • This sealing ring 4 has a circumferential sealing lip 6 on its outside, cf. Figure 6, which is designed as a projecting circular ring.
  • the sealing ring 4 is fixedly arranged on the sealing cap 2 via the sealing lip 6.
  • the sealing ring 4 is provided with a crossbar 3, which is thus indirectly fixedly arranged on the closure cap 2 or the neck of the container 1.
  • a reinforcing plate 5 is assigned to the sealing ring 4, a film hinge 7 being arranged between the sealing ring 4 and the reinforcing plate 5 as a connecting element. This ensures easy mobility of the gain adjuster 5.
  • the crosspiece 3 runs below the center of the reinforcement plate 5, which is provided with two openings 8 arranged on the side of the crosspiece 3.
  • the sealing ring 4 with its cross bar 3 and the reinforcement plate 5 are enclosed by a softer molded material 10.
  • a material accumulation 9 is injection-molded onto the underside of the reinforcement plate 5 to the side of the crossbar 3 in the central region thereof.
  • the transition from the material accumulation 9 to the rest of the injection molded softer material 10 has an arcuate boundary.
  • the accumulation of material 9 runs according to the bottom view.
  • Figure 9 perpendicular to the crossbar 3 and has a rectangular shape.
  • the molded softer material 10 also serves as a seal.
  • the reinforcement plate 5 can be raised all around or only partially by an internal pressure to form an opening.
  • the circumferential opening is formed by a circular ring which is formed between the inside of the sealing ring 4 and the outer boundary of the reinforcement plate 5, cf. Figure 4.
  • the reinforcement plate 5 is only partially raised, because the reinforcement plate 5 is prevented from moving upward on a predetermined circumferential area.
  • an anchoring rib is injection molded onto the sealing ring 4 and inserted into a recess in the reinforcement plate 5.
  • the front end of the reinforcement plate 5 is provided with a cover 12 which can be clipped onto the outer wall of the sealing ring 4.
