FR2778640A1 - Reusable plug with central female helicoidal screw thread - Google Patents

Abstract

The reusable plug has a central female helicoidal screw thread (1) which can be engaged by a male helicoidal screw, such as a corkscrew in order to remove it without any deterioration. The plug has a lower zone (B) for re-plugging for a short time and an upper zone (A) for re-plugging for an extended period. The lower zone comprises beading (3) forming projections in order to limit the pressure which is applied during plugging.

Description

The present invention relates to a reusable cylindrical plug whose

  central part 1, embedded in the material is composed of a female helical screw

(see sketch 1).

  Most corks are not reusable, because when uncorking a bottle (wine bottle for example) the cork is most often pierced through and through, and therefore ventilated the liquid to be stored, which

detracts from the quality of the content.

  The device according to the invention makes it possible to remedy this major drawback thanks to the corkscrew having a platform perpendicular to the extraction axis, this axis or, male helical screw is the same length as the part t 1 shown on on the sketch 1. Thanks to this helical screw embedded in the material (part 2) the user of the type of this stopper will be able to unclog over and over, and again and again, with great ease, the bottles or the containers (of various shapes) thanks at

  this set: "helical screw-cap-corkscrew-platform".

  This stopper has another novelty: in fact, the area B (see sketch 1) is narrower than the upper part A, and has three flexible roundnesses (3 flanges of 360) forming a relief on the part B. The diameter lower in zone B allows the user of this new type of cork to stopper, and, to recap the bottle very easily, thanks to a

at the touch of a thumb.

  4, shows the rounded edges of the plug in order to facilitate intrusion

  The corkscrew (see sketch 2) adapted to the i1 spiral (female helical screw) of the cork allows easy extraction thanks to its perfect guidance.

  The spiral 1 embedded in the solid material serving as a guide and,

  extraction system (see sketch 1).

  Zone A will therefore be reserved for a long shutter, zone B,

  for a short filling of a few days or even a few hours.

  The attached sketches (1 and 2) illustrate the invention. Sketch 1 shows the internal detail of the stopper: zone A, and, external zone B (A: long-term stoppering

  B: short-term blocking). Sketch 2 shows the detail of the corkscrew.

  It is therefore thanks to this perfect guiding of the corkscrew that the operation can be repeated over and over again without shredding the material as is the case.

  more often the case for other types of caps.

  This device will be an important source of savings for the user.

  The type of corkscrew (see sketch 2) is detailed as follows:: the handle (or pull-out wrist) 6: the stop platform, 7: the spira-

  -the same length as the spiral 1 (see sketch 1) of the cap.

  This type of plug is reserved for ALL users (for example:

lovers of good wines).

Claims (4)

  1. Reusable stopper for bottles characterized by the fact that it has a central part (1) provided with a female helical screw thread capable of cooperating with a corkscrew provided with a male helical screw (7) for uncorking convenient without deterioration of the cap.   2. Reusable bottle stopper according to claim 1 characterized in that it has - a lower zone (B) for short-term refills; - an upper zone (A) for additional fillings long duration.   3. Reusable stopper for bottles according to claim 2 characterized in that the lower zone (B) has beads (3) forming a relief on said zone (B) to limit the pressure to apply when capping.   4. Reusable bottle stopper according to one   any of claims 1 to 3 characterized by the fact   That it has a rounded lower edge (4) in order to   facilitate the introduction of the plug.
