Definitions

  • the present invention relates to caps for sealing bottles, jars and other receivers, of the type comprising a bottom and a corrugated skirt extending around the bottom.
  • crown type caps are generally used for sealing receivers having a neck terminated by a bead.
  • the latter is placed on the neck mouth and the skirt is then tightened around and under the bead, thus firmly engaging the re DC neck.
  • Such caps have a sharp edge and this causes many inconveniences which will be mentioned hereinafter.
  • FIG. 3 shows the manner in which any kind of vessel or receiver, which in the example shown in a jar for preserves 12, can be sealed by means of a cap according to the invention.
  • the sealing device (not shown) applies the cap against the mouth of the jar, and a reciprocating sleeve, while urging skirt 2 towards the neck of the jar,
  • FIG. 1 shows, in elevation and partly in section, a cap i according to the invention
  • FIG. 2 is an enlarged perspective view of a portion of v the inner surface of the cap of FIG. 1;
  • FIG. 3 shows, partly in elevation and partly in section
  • FIG. 4 shows a cap according to the invention while it is being separated from a stack of such caps
  • FIG. 5 shows another embodiment of the cap according to the invention.
  • a cap according to the invention may be obtained, for example, from an aluminum or tin plate stamping blank. It comprises a bottom 1 and a flared skirt 2 having a noncontinuous rounded rim 3.
  • Rim 3 is formed with rounded claws 4 which would at first sight appear to be of a rather conventional type.
  • the rounded claws 4 formed at the rim of skirt 2 are separated from each other by cut-outs 5 and 6. For the sake of clarity, one of the claws is shown unfolded in FIG. 1 at 11.
  • FIG. 2 The shape of the notches or corrugations with which skirt 2 is provided is more particularly shown in FIG. 2.
  • These corrugations are of a conventional type. However, it should be noted that they do not extend until the edge of the skirt and that a portion of the skirt rim which is rounded, i.e., outwardly upturned in the embodiment of FIG. 1, is not provided with corrugations or notches. This important feature of the invention may be particularly observed from FIG. 1, wherein one claw 11 is shown unfolded, and from FIG. 2.
  • each upturned claw portion extends over a length corresponding to two corrugations 7 and 8.
  • the scaling is performed in the same manner as in conventional corrugated caps, i.e., those having no rounded rim portion.
  • the scaling is not performed by virtue of the claws which are not the sealing element properly speaking and this distinguishes the cap according to the invention from certain known caps having no corrugations or notches and wherein the sealing operation is performed by a rounded rim only.
  • the rounded rim portion need not and actually does not intimately engage the neck portion 13 of the sealed jar 12.
  • claws 4 pivot under the action of the closing sleeve, they come nearer to each other, the cut-outs between the claws being thus closed and, when the sealing operation has been performed, adjacent claws contact each other.
  • caps according to the invention are particularly convenient for stacking and are thus particularly suitable for use in automatic sealing machines.
  • a separation member is readily inserted between the respective rounded rims 15 and 16 of two caps stacked upon each other, without any danger of scratching the varnish covering the cap. It is obvious that such a stacking is not possible with conventional caps having sharp edges.
  • cap according to the invention is strengthened by the rounded rim. A substantial pressure may be exerted on the cap during the sealing operation without any risk of the caps bottom being deformed. This may result in the further advantage of making it possible to use caps of thinner material.
  • FIG. 5 shows another embodiment of a cap according to the invention.
  • the external surface of the cap, once the sealing has been performed should be entirely smooth. It is also sometimes desirable that no portion of the inner surface should be visible as, for example, when the color of the inner surface of the cap is not the same as that of its outer surface. Such is obviously not the case with the outwardly upturned rounded rim of the cap of FIGURES 1 to 4.
  • the rim portion may be inwardly upturned as shown at 18 in FIG. 5, instead of being outwardly upturned as in FIG. 1.
  • the cap of FIG. 5 is entirely similar to that of FIG. 1.
  • the cap shown in FIG. 1 or 5 may also be used for tightly sealing a neck provided with a screw thread or other protruding portion adapted for screwing.
  • the skirt corrugations undergo deformation and provide close engagement of the cap with the neck of the container.
  • unscrewing the cap the user entails no risk of hurting his fingers by virtue of the rounded rim of the cap.
  • a cap of the crown type for sealing the mouth of a vessel which has a peripheral bead, said cap comprising a bottom portion adapted for .resting on said peripheral bead to cover the mouth of the vesselja depending skirt on said bottom portion extending beyond said peripheral bead when the bottom portion rests on theimouth of the vessel, said skirt having corrugations and a5 smooth cor rugation-free terminal rim portion, said rimlportion hav ing a free edge and spaced cut-outs extending from said free edge towards said corrugations and fdefining claws which are upturned and which are separated from one another by said cut-outs, and said cut-outs being restricted to said corrugation-free terminalrim portion and extending to a position spaced from the corrugations to provide a smooth portion in said 'ski'rt between the corrugations and the rim portion containing the cut-outs, said cut-outs having a width sufficient to cause adjacent upturned claws to laterally contact each other as said corrugations on said skirt are brought into
