FR2657068A2 - Efficient pouring stopper for container and cardboard package - Google Patents

Abstract

Efficient pouring stopper fitting into a cardboard container of the type described in the main patent. It comprises an inverted cone 18, provided with a perforating point 19, extending a cylindrical tubular sleeve 1. The cone and the sleeve have their surfaces scattered with passage holes 20 which allow the passage of a liquid or powder. When the perforating point is pressed against the wall of a container, it penetrates into the cardboard of that wall. The device is intended for the opening and automatic instantaneous re-sealing of cardboard containers and packages of the liquid or powder-pack type.

Description

The main patent describes: o S.I72'j a pouring plug
safety, anti pollution, with programmed flow regulator,
opening and closing by itself by gravity, and intended to be
positioned in the neck of a container containing a liquid.

If it is true that we can easily retract the cap
in a container with a neck, it becomes practi
hardly impossible to introduce it rel what in a kind of story
pient in the form of cardboard packaging, box type
card stock such as, for example, packs sold commercially
ce, intended for the packaging of liquids, in particular drinks
or powders.

The object of the present invention is to produce a pouring plug.
of the type described in the main patent and which ensures by its nature
even normal, practical, efficient penetration, making an intro
instant duction in a wall of this type of container for
allow its opening, and especially its automatic closing by
gravity.

This result is achieved according to the invention by means
new which will now be described with reference to a mode
for carrying out the invention. For this we must refer to
attached drawings in which that of Figure I illustrates as
example a sectional view of the perforating pouring plug according to
the invention.

 FIG. 2 shows a perspective view of the perforating pouring plug according to the invention.

The cap of Figure I is made of hard, rigid plastic, which may be of the iXylon (registered trademark) type; The fixed part
is a tubular cylindrical sleeve l, conical in the direction of its
base which extends into a surface forming an inverted cone 18 of which
the tip of the apex is characterized by an acute point 19,
perforating, intended to pierce and pass right through the wall
cardboard container and allow the introduction of the cap
anywhere on any of its faces. The sleeve
tubular and cone are characterized by a perforated surface,
dotted with holes separated from each other, representing openings
transit tures 20, intended to allow the free passage of li
quides or powders through the body of the pouring cap.

The cap of Figure 2 shows in perspective the cone comprising
in the direction of its height an admission light 21 which is charac
térise by a rectangular opening of a sufficient size Jur allow easy access to the regulating ring located on the rod 11 in order to be able to move it to adjust the opening of - the spupape 9.

 To introduce and adapt the stopper to the container, simply press the piercing point in pressure on the wall to create a hole equal to the outside diameter of the sleeve, then push it fully into it by performing a rotary movement which causes the progressive tearing of the cardboard material, which is pushed back into the container and spreads circularly without falling inside. This perfectly positions the plug which closes it by pressing against the surface of the wall. The plug is in place, it then becomes operational.

 While tilting the container, it opens alone. When it is straightened, it recovers itself by gravity.

 To remove the plug, simply release it from the hole by pulling it up.

 The perforating part of the pouring plug attached to the main patent therefore makes it possible to make the plug penetrate very easily into any container or packaging made of cardboard material as often as necessary by ensuring an operation allowing opening and compulsory automatic filling of the latter.

The perforating pouring cap is also designed to avoid opening (as is currently the case) a cardboard container by tearing and removing a piece of its wall to make a pouring opening which can no longer be closed again to enclose and protect the remaining content.

 It is intended to be used by consumers of drinks packaged in cardboard paper packaging, of the Pack type, for example. In particular packs of wine, milk, sodas, fruit juices etc. and all food fluids in general.

 It can also be used for pouring powdered products, for example detergents.

It is intended to be used in the manufacture, exploitation and marketing in the industry of packaging in dobby drips containing liquids or powders.

Claims (3)

CLAIMS. 1 / Pouring cap attached by addition to the main patent N 89.1720S according to claim 1 of this patent. Characterized in that it comprises a cylindrical perforating sleeve 1, tubular, conical in the direction of its base which is extended to form an inverted cone 18 the apex of which is a point 1S of hard material intended to perforate and pass through the wall of a cardboard container by creating a hole equal to the outside diameter of the sleeve 1 and thus allow the introduction of the plug into the container. 2 / Device according to the preceding claim characterized in that the sleeve 1 and the cone 18 have a surface dotted with perforations which are transit openings 20 intended to allow the free passage of liquids or powders. 3 / Device according to claim 8 of the main patent and the preceding claims taken as a whole characterized in that the cone 18 has in the direction of its height a rectangular opening which is an intake light 21 of sufficient size to allow the '' access to the sliding ring to adjust the opening of the valve 9.
