Definitions

  • the present invention relates generally to a closure and particularly to a dispensing closure.
  • the present invention seeks to address the problems with known dispensing closures.
  • a closure comprising a base with a dispensing orifice, a lid, and catch means for holding the lid in a closed position, in which the closure further comprises a resilient part which is caused to be in an energised state in the closed position, such that when the catch means is released the resilient part causes the lid to move to or towards an open position.
  • the base and lid may be connected by a hinge.
  • the resilient part may be provided by the lid and/or the base.
  • the part may form part of the lid and/or base or may be a separate component carried on or by the lid and/or base.
  • the resilient part may be formed as part of the structure of the lid or base, such as a side or top wall.
  • the resilient part may form at least part of the lid top plate.
  • the lid or base may comprise the resilient part.
  • the resilient part may be adapted to seal the dispensing orifice in the' closed position. This therefore gives an additional benefit.
  • the base may comprise a dispensing spout.
  • the resilient part may be carried on or by the lid and caused to deform by the spout in the closed position whereby to energise it.
  • the resilient part may be formed by bi-injection moulding with the lid or base component.
  • the resilient part may be formed from an elastomeric material, such as a thermoplastic elastomer. Such materials provide the required resilience and may be selected also to provide a seal if required.
  • a container having a closure as described herein.

  • Figure 2 is ⁇ section of the closure of Figure 1 ;

  • Figure 7 is a perspective view the closure of Figures 5 and 6 shown in an open position; and Figure 8 is a side elevation of the closure shown in Figure 7.
  • the closure 10 comprises a generally cylindrical body having a base 15 and a lid 20 joined together by a hinge 25.
  • the base 15 comprises a generally cylindrical sidewall 30 partially closed at one end by a disc-shape top plate 35.
  • the top plate 35 includes a central orifice 40 defined by a cylindrical dispensing spout 45 which projects away from the open end of the sidewall 30.
  • the interior of the sidewall 30 is provided with screw thread formations 50 for engaging corresponding external screw thread formations (not shown) provided on a container neck 1.
  • the top plate 35 includes an upstanding hook member 55 which is positioned slightly inboard the periphery of the top plate 35 and diametrically opposite the hinge 25.
  • the lid 20 comprises ⁇ generally cylindrical sidewall 60.
  • the sidewall 60 is closed at its end opposite the base by a top plate 65.
  • the top plate 65 comprises inclined step 70 which is continuous with the sidewall 60, and a central resilient part 75.
  • the step 70 is annular and the part 75 is positioned within the central opening defined by the step 70.
  • the sidewall 60 and step 70 are formed from polypropylene and the central part 75 is formed from a thermoplastic elastomeric material.
  • the open end of the sidewall 60 includes a catch element 80.
  • the lid 10 With the closure 10 in the closed position shown in Figures 1 and 2, the lid 10 covers the base 15 and the catch 80 engages under the hook 55 to retain the lid in position.
  • the resilient part 75 is pushed down onto the spout 45 and due to the nature of the part material it is deformed over the harder material of the spout as shown best in Figure 2 so that is if held under tension. In this position the part 75 seals over the opening 40.
  • the lid When the contents of a container are required, the lid is opened by releasing the catch 80 from under the hook 55. This is achieved by pushing on the base. 15 at a point diametrically opposite the hinge 25 defined by a depression 16 so that the hook 55 is displaced rearwardly as illustrated by arrow A. With the catch 80 released the energy stored within the part 75 causes the lid automatically to flip open as illustrated by arrow B and shown in Figures 3 and 4 to reveal the dispensing orifice. The part 75 assumes a generally dome-shape configuration. When dispensing is complete the lid can be forced back into the closed position, thus again deforming it over the spout and ready for a further release step.
  • the closure 10 is moulded approximately in the position shown in Figure 4 in which the lid 20 is in an open position and the resilient part 75 is in a relaxed state.
  • the closure 10 is produced in a bi-injection moulding process in which the base 15 together with the sidewall 60 and step 70 of the lid 20 are first formed from polypropylene and subsequently the resilient part 75 is added in a secondary moulding operation which • bonds it to the step 70.
  • FIG. 5 to 8 there is shown a closure 1 10 formed according to an alternative embodiment.
  • the closure 110 is very similar to the closure 10 shown in Figures 1 to 4 except that there is no hook and catch arrangement.
  • the lid sidewall 160 is provided with a flat 185 diametrically opposite the hinge.
  • the top plate 135 of the base 1 15 is provided with a flat step 190 onto which the flat 185 of the lid can rest.
  • An interference fit is provided between the lid and the base.
  • Operation of the closure 1 10 is the same as the closure 10 in that the lid is held in the closed position against the biasing effect of the resilient part 175.
  • the step is moved rearwardly with respect to the flat so that the interference fit is released allowing the spring effect of the resilient part 175 to flip the lid open.
  • the base provides the resilient part.
  • the base could include a trampoline-like element and the lid could include a projection which is pressed into the trampoline in the closed position so that upon release of a catch arrangement the trampoline element forces the lid away from it.

Abstract

L'invention concerne un bouchon (10) comprenant une base (15) munie d'un orifice de distribution (40), un couvercle (20) et un élément de retenue (55, 80) destiné à maintenir le couvercle dans une position fermée. Le bouchon comprend en outre une partie élastique (75) qui est mise en tension dans la position fermée, de sorte que lorsque l'élément de retenue est libéré, la partie élastique provoque le déplacement du couvercle dans ou vers une position ouverte.
