Definitions

  • the invention relates to a closure for cans provided with a bead according to the features listed in the preamble of the main claim.
  • the invention has for its object to further develop the known can closure so that it provides an effective seal of the can even with increased internal pressure due to gas evolution and is independent of the size of the pouring opening.
  • DE-U-77 37 634 also strives to have a sealing sleeve act on the edge of a can lid opening.
  • this is a piece of rubber hose provided with transverse waves, which is guided on a hollow cylindrical mandrel.
  • This front beveled mandrel is to cut an opening in the can lid, the sealing sleeve having the task of sealing a gap that may arise between the mandrel and the edge of the opening formed.
  • the invention differs from this in that a completely free opening of the can lid, which need not be penetrated by a mandrel, can be effectively sealed.
  • the base body is plate-shaped and the closure is made in one piece, the base body has a certain elasticity.
  • the closure which can be pressed onto the can in the manner of a snap lock over the edge bead, will therefore curve slightly convexly when the internal pressure in the can is increased, which leads to an even firmer clamping of the closure to the can. Due to the simple shape, the can closure according to the invention can be produced in the cheapest way as a plastic bulk article.
  • 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.
  • a curved end edge web 2 which is adapted to the diameter of the can or its edge bead and which an inwardly projecting nose 3 engages under the rim of the can.
  • a further front edge web 4 which has a resilient wall section 5.
  • 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 inwardly 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.
  • the starting point here is cans (see FIG. 6), in the cover of which there is a zipper which leaves an approximately triangular pouring opening 25 after tearing.
  • 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 end edge webs 2, 4 or the distance of the lugs 3, 6 from the base body 1 is dimensioned such that the closed bead web 8 presses the sealing disk 9 firmly against the can lid in the clipped-on state.
  • 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 engage under the bead of the can.
  • the dimensioning of the front edge web 4, 5 is selected 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 pouring spout 12 can also be connected to the base body 1, which leads the sealing disk 9 with a projection 13, can be closed with a cap 15 and has a ventilation tube 14 which extends from 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 largely assumes its shape when inserted into the guide web 18. Accordingly, an end face of the sealing ring 19 seals the can lid area which surrounds the pouring opening 25 (cf. 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 19. In this area, the sealing ring 19 is compressed more 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 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 lugs 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.
  • 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.
  • a suitable, known angular design of the legs of the clamping bracket 34 it can be achieved that when the clamping bracket 34 is pivoted away, the latter reaches a dead center position and the support leg 35 is thereby pressed firmly against the lower surface of the edge of the can.
  • the clamping bracket 34 is formed from spring steel wire, it is sufficient if the support legs 35 are correspondingly angled ends of this wire, which form an obtuse angle to one another.
  • 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 is initially provided on the base body 1 on the can side at the outlet of the pouring hole 36, the function of which can be understood in connection with the clamping lid 21 shown in FIG. 10, which - as already explained for FIGS. 4 and 5 - is pressed against the base body 1, to clamp 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, when assembling the web 39 comes to rest on the wall recess 37. But since the web 39 has a wall opening 41, the interior of the. Approach 38 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.
