Definitions

  • the invention relates to a closure for cans provided with an edge bead, in the lid of which there is a predominantly triangular pouring opening to be formed by a tearable wall part, the closure having a front edge web engaging under the edge bead of the can and a seal covering the edge of the pouring opening .
  • a closure with these features has become known from DE-GBM 77 37 634, which, however, can also be used for cans without a zipper.
  • a metallic base body enclosed by a plastic handle engages behind the rim of the can with a nose.
  • a pouring neck is formed on the base body with a sharp oblique edge, which cuts into an opening when pressed onto the can lid.
  • a hook-shaped hole tool is formed on the base body in the form of a mandrel, which also penetrates through the can lid and gets caught in the process so that the closure cannot be easily lifted off.
  • the invention is therefore based on the object of producing a can closure from a plastic body which can be firmly connected to the can, can be produced in the simplest way and yet ensures adequate sealing of the can even with increased internal pressure due to gas development.
  • the essence of the invention is that the front edge web of the closure, which is made entirely of plastic, has a curvature which is adapted to the diameter of the can edge bead, and another front edge web is arranged opposite it on the plate-shaped base body at a distance corresponding to the can diameter, one has resilient wall portion with a nose under the can edge bead.
  • the base body is plate-shaped and the closure is made in one piece, the base body has a certain elasticity.
  • the snap-on closure which can be printed onto the can in the manner of a rim, will therefore curve slightly convexly when the internal pressure in the can is increased, which leads to an even tighter locking of the closure to the can.
  • the can closure according to the invention can be mass-produced in the cheapest way.
  • the advantage is achieved that a special vent tube is unnecessary and that the liquid can content can be poured out in a uniform flow.
  • the closure shown consists of a plate-shaped base body 1, the wall thickness of which is dimensioned such that this base body is elastically deformable.
  • On the wider face of the base body there is a curved face edge which is adapted to the diameter of the can or its edge bead web 2, which engages under the rim of the can with an inwardly projecting nose 3.
  • the resilient wall section 5 is spaced apart from the rigid parts of the front edge web 4 according to the cutouts 7.
  • the resilient wall section 5 also has an inside projecting nose 6, which engages under the rim of the can like a snap lock when the closure is placed on the can from above.
  • a pin 10 which is integrally formed on the base body 1, engages in this pouring opening of the can.
  • This pin 10 delimits with a front projection 11 (mushroom-like configuration) a sealing washer 9, for example made of rubber, which rests on the inside against a closed bead web 8 of the base body 1, the cross section of which can taper in a wedge shape.
  • the free surface of the sealing washer 9 lies on the top of the can lid, namely in the region of the edge of the pouring opening.
  • the height of the front edge webs 2.4 or the distance of the lugs 3.6 from the base body 1 is dimensioned such that in the clipped-on state the closed bead web 8 presses the sealing disk 9 firmly against the can lid.
  • the rigid front edge web sections 4 are supported on the outer surface of the can edge bead and thus clamp the opposite front edge web 2 so tightly that its projecting nose 3 securely engages under the edge bead of the can.
  • the projecting nose 6 of the resilient wall section 5 is also able to reach under the rim of the can.
  • the dimensioning of the front edge web 4.5 is chosen so that on the one hand the bracing between the rigid web parts 2.4 is possible and yet the resilient wall section 5 can snap away over the can edge bead.
  • a spout neck may be connected 12 that leads with a projection 13, the sealing plate 9, is closed by a cap 15 and a Bellustun g srschreibchen 14 has that of the Cap 15 is covered tightly in the closed state.
  • An edge bead 16 is provided on the pouring spout, which is encompassed by a corresponding recess in the cap 15 in the manner of a snap lock.
  • a hinge 17 can be formed in a suitable manner, which holds the cap 15 in non-easily separable connection with the closure.
  • the embodiment of Figures 4 and 5 differs from that of Figures 1 and 2 in the way in which the seal is constructed and effective.
  • the base body 1 has on its underside a circumferential, approximately oval closed guide web 18, on the inner surface of which a sealing ring 19 is guided and supported. It is advisable to design this sealing ring 19 in its original shape as a hollow cylinder, the wall thickness being less than the wall height. Due to its elasticity, the circular sealing ring 19 takes on insertion into the guide web 18 largely its shape. Accordingly, an end face of the sealing ring 19 seals the can lid area which surrounds the pouring opening 25 (see FIG. 6). It is now desirable that the seal be all the more intense where the pouring opening 25 is widest.
  • a raised pressure surface 20 is provided on the underside of the base body 1, which acts on the assigned area of the sealing ring 39. In this area, the sealing ring 19 is compressed to a greater extent when the closure is clipped onto the can than the rest of the sealing ring area.
  • the holding and guiding of the sealing ring 19 is effected with the aid of a clamping cover 21 which has a series of bores 23 into which correspondingly designed pins 22 of the base body 1 engage.
  • the edge of the clamping cover 21 is adapted to the shape of the sealing ring 19 held by the guide web 18. In some places, cutting-edge projections 24 extend outwards from this edge. If one presses the clamping lid 21 with its bores 23 onto the pins 22, then the cutting-shaped projections 24 engage in the inner wall area of the sealing ring 19 while pressing it against the pressure surface 20 ′ and the slightly set back other surfaces of the base body 1.
  • FIG. 6 it is shown for better clarity how the closure according to the invention rests on the can.
  • the invention provides in the exemplary embodiments in FIGS. 7 and 8 that at least one of the noses under the can edge is arranged on the base body 1 so as to be adjustable or displaceable and thus an adaptation to the diameter of the can can be reached.
  • the projecting nose 6 is located on a tensioning element 26, which engages through a slot 28 in the base body 1 and is supported like a shoulder on the underside of the base body 1.
  • a bearing 29 for pivoting an eccentric lever 30 is arranged on the upwardly projecting web 27, which in turn acts on the surface of the base body 1.
  • an edge web 32 with a bore 33 is provided on the base body 1, in which a clamping bracket 34, preferably made of spring steel wire or sheet metal, is rotatably mounted.
  • This clamping bracket 34 has shorter support legs 35 which pivot clockwise inward under the can rim when the clamping bracket 34 is pivoted.
  • FIG. 3 a variant of FIG. 3 is now shown, which pursues the goal of providing a pouring spout 12 with a single pouring hole 36 and to make the vent hole 14 shown in FIG. 3 unnecessary.
  • a wall recess 37 At the bottom Body 1 is first provided on the socket side at the outlet of the pouring hole 36, a wall recess 37, the function of which can be understood in connection with the clamping lid 21 shown in FIG. 10, which - as already explained for FIGS tighten and center the sealing ring 19.
  • This tensioning cover 21 has a shoulder 38 with a web 39, as a result of which the shoulder 38 is given the shape of a U with a bottom. Beyond the web 39 there is a flow opening 42 which is congruent with the pouring hole 36 of the pouring spout 12. Consequently, the web 39 comes to rest on the wall recess 37 when the web is assembled. However, since the web 39 has a wall opening 41, the interior of the extension 38 is connected to the pouring hole 36 through the wall opening 41 or the wall recess 37. When pouring out, the cavity in the can, which is not taken up by the liquid, can be connected to the pouring hole 36 via the opening 40 in the extension 38 and the wall opening 41, 37.
