Definitions

  • the present invention relates to a sealed closure assembly with retractable pouring tube with multidirectional orientation, intended to be used in cooperation with containers, and in particular cans containing oils, lubricants and other similar products.
  • Canisters were then proposed provided with a separate pouring tube, intended to be placed on the neck of the canister when the product was poured.
  • This mono ⁇ lithic pouring tube which comprises a base connected to a flexible portion in the form of a bellows with memory effect, is intended to allow precise pouring of a liquid in any direction.
  • This base has a thread complementary to the external thread of the canister neck, in order to allow the pouring tube to be screwed onto said neck. It should be noted that the thread formed outside the neck is intended, conventionally, to allow the closure of the container by means of a plug.
  • this pouring tube has the drawback of not being an integral part of the container and thus, when the latter is closed, of being stored separately.
  • it is never safe from residual lubricant stains on the walls of the tube after use, or the risk of penetration of dust and other impurities in the can, which risks clogging the lubricated material during the pouring of the lubricant by means of said tube.
  • the present invention overcomes these drawbacks. It aims for a sealed closure assembly with retractable pouring tube, multidirectional orientation easy and economical to manufacture, convenient to use and forming part of the container, without being permanently attached to the latter, so as to facilitate the precise pouring of the content of the container. or filling it.

  • the lower end of the internal branch having a shoulder against which the lower end of the bellows comes to bear, the upper end of which is pressed against the internal face of the corolla of the plug.
  • the present invention is characterized in that a retractable pouring tube with multidirectional orientation is associated with an intermediate element of suitable shape on the one hand, with said pouring tube and on the other hand , at the neck of a container. In this way, the pouring tube is permanently inside the container.
  • a “bellows” is a flexible portion formed by a succession of straight folds arranged in an accordion.
  • a “memory effect bellows” is a bellows which can be stretched and inclined in a determined position under the effect of a first force, and which, under the effect of a reverse force, returns without distortion sensitive to its initial position or in another position.
  • the characteristic intermediate element comprises on the external face of its external branch an annular ring intended to cooperate with a complementary ring arranged on the lateral internal face of the closure cap;
  • the external branch of the intermediate element is intended to be clipped or screwed onto the threaded external face of the neck of the container;
  • the internal face of the corolla of the closure plug has an internal cylindrical crown, intended to cooperate with the upper end of the bellows for sealing;
  • This cylindrical crown comprises a plurality of clipping sectors directed outwards and intended to cooperate with an annular zone formed for this purpose at the upper end of the pouring bellows;
  • the lower end of the bellows is extended by a cylindrical portion which penetrates into the container, and the external face of which is disposed in the vicinity of the end has a projection and a stop providing space corresponding to the length of the shoulder disposed at the end of the internal branch of the intermediate element, to embed the end of this cylindrical por ⁇ tion on said shoulder;
  • the external branch of the intermediate element is threaded on its two faces, respectively on its internal face to cooperate with the external thread of the neck, and on its external face with the internal thread of the plug;
  • the base of the neck has vertical notches intended to oppose the rotation of the intermediate element on the neck;
  • the bellows-shaped portion consists of a stack of straight folds, arranged in an accordion, the thickness of which is reduced in the areas of connection from one fold to the other.
