Abstract

Disclosed is a pouring device suitable for piercing and emptying a granular material contained in a vacuum-sealed package, including: a tubular body, having a duct for the flow of the material, extending from an inlet opening positioned at a first end of the tubular body to an outlet opening for the granular material, positioned at a second end of the tubular body; and a hollow piercing tool having a distal end ending in a pointed tip, and a widened base at the proximal end thereof, rigidly connected to the body. The device further includes a shoulder serving as a stop coming into contact with the wall of the package to stop the pouring device when the wall is pierced by the piercing tool, and possibly a bowl bringing the granular material having escaped the hollow portion of the piercing tool into the inside of the hollow portion by gravity.

First claim

The invention claimed is:

1. Pouring device suitable for piercing and emptying a granular material contained in a vacuum-sealed package, comprising:
a tubular body, having a duct for the flow of the material, extending from an inlet opening positioned at a first end of the tubular body to an outlet opening for the granular material, positioned at a second end of the tubular body,
a hollow piercing tool having a distal end ending in a pointed tip and a widened base at the proximal end thereof, rigidly connected to the tubular body at the first end of the tubular body, the piercing tool having at least one lateral opening along the length of the piercing tool, said lateral opening extending along the length of the piercing tool from the widened base of the piercing tool, said lateral opening being configured to allow the material to be poured from the outside to the inside of the hollow portion of the piercing tool, the hollow portion of the widened base of the piercing tool communicating with the inlet opening of the tubular body, and
a shoulder serving as a peripheral stop, formed by the first end of the tubular body arranged around the widened base of the piercing tool, said shoulder serving as a stop being configured to come into contact with the wall of the package to stop the pouring device when said wall is pierced by the piercing tool in a position in which said lateral opening extends to the inside of the package,
wherein said pouring device is configured to ensure the continuous emptying of the contents of the vacuum-sealed package when the pouring device is oriented vertically, the pointed tip pointing upward, the granular material flowing by gravity through said lateral opening via the inlet opening and to the outlet opening by gravity in the opposite direction of an air entering the vacuum-sealed package, and
wherein the piercing tool comprises a locking groove intended to receive the wall edge of the package directly, or indirectly via an annular ring rigidly connected to the wall of the package, said locking groove being configured so as to hold the piercing tool once the package has been pierced by the piercing tool, said groove being formed by a plurality of notches located on a same radius with respect to the axis A of the piercing tool.

2. The pouring device according to claim 1 , wherein said shoulder serving as a stop is configured to come into contact with the wall of the package to stop the pouring device when said wall is pierced by the piercing tool in a position wherein said lateral opening extends along a first portion of length inside the package and along a second portion of length outside the package where said lateral opening forms an air inlet, and wherein said shoulder is at a distance radially from the widened base of the piercing tool, the pouring device comprising a bowl formed on the first end of the tubular body, arranged along the periphery about the piercing tool, positioned intermediately between said shoulder and the widened base of the piercing tool, the slope of the bowl being angled toward the piercing tool and configured, when the piercing tool is oriented vertically, the pointed tip of the piercing tool pointing upward, so as to bring the granular material having escaped the hollow portion of the piercing tool into the inside of the hollow portion by gravity, through the second portion of length of the lateral opening.

3. The pouring device according to claim 2 , wherein the widened base of the piercing tool having an outer radius R 1 in relation to an axis of the piercing tool, the lower part of the bowl having a recess at said lateral opening, at an additional depth of the wall of the bowl communicating with the duct of the tubular body, said recess being configured so that the inlet opening extends radially on the outside beyond the outer radius R 1 of the widened base of the piercing tool, at least to the location of said at least one lateral opening.

4. The pouring device according to claim 3 , wherein the inlet opening extends to the location of the lateral opening up to a radius R 2 with respect to the axis A of the piercing tool, which is greater than the outer radius R 1 of the widened base of the piercing tool.

5. The pouring device according to claim 1 , wherein the piercing tool has the shape of an ogive comprising ogive arches, each of which extending from the widened base of the piercing tool to the pointed tip of the piercing tool where said ogive arches meet, said at least one lateral opening comprising a plurality of lateral openings, each lateral opening extending from the widened base between two consecutive ogives arches over all or part of the length of the piercing tool in the direction of the pointed tip.

6. The pouring device according to claim 1 , wherein said notches are positioned according to the axis A of the piercing tool level with said shoulder according to the direction of the axis A, at a distance from the widened base of the piercing tool according to said direction of the axis A, and in such a way that said lateral opening extends upward when the wall of the package is locked by the notches of the locking groove, both inside the package on said first portion of length of the piercing tool located between the pointed tip and the locking groove, on the one hand, allowing the granular material to be poured into the piercing tool, and outside the package on the second portion of length of the piercing tool between the locking groove and the widened base, where said lateral opening forms said air inlet, on the other hand.

7. The pouring device according to claim 1 , wherein the assembly of the tubular body and the piercing tool is a portable hand tool, suitable for being worked manually, configured to manually pierce and empty the granular material from a vacuum-sealed package.

8. Vacuum-sealed package containing a granular material, as well as an annular ring rigidly connected to the wall of the package, configured to lock in the locking groove of a pouring device according to claim 1 .

9. The package according to claim 8 , wherein the outside surface of the sealed wall of the vacuum-sealed package at the annular ring, intended to be pierced, is sanitized and isolated from external contamination by a peelable sheet intended to be removed before piercing.

10. Production unit comprising an enclosure which is a fermentation tank as well as a pouring device suitable for piercing and emptying a granular material contained in a vacuum-sealed package, comprising:
a tubular body, having a duct for the flow of the material, extending from an inlet opening positioned at a first end of the tubular body to an outlet opening for the granular material, positioned at a second end of the tubular body,
a hollow piercing tool having a distal end ending in a pointed tip and a widened base at the proximal end thereof, rigidly connected to the tubular body at the first end of the tubular body, the piercing tool having at least one lateral opening along the length of the piercing tool, said lateral opening extending along the length of the piercing tool from the widened base of the piercing tool, said lateral opening being configured to allow the material to be poured from the outside to the inside of the hollow portion of the piercing tool, the hollow portion of the widened base of the piercing tool communicating with the inlet opening of the tubular body, and
a shoulder serving as a peripheral stop, formed by the first end of the tubular body arranged around the widened base of the piercing tool, said shoulder serving as a stop being configured to come into contact with the wall of the package to stop the pouring device when said wall is pierced by the piercing tool in a pos
