Description

The present invention relates to a pouring device on a container for

spillable products, comprising a tubular pouring part opening into the container and a closing part which is made integrally with the pouring part and is gas and liquid tight connected to it, the closing part being able to be detached from the part of

pouring for the first opening of the pouring device.

Known containers or sachets, preferably made of a thermoplastic material, for packaging spillable products, such as powders or liquids, as well as for

pasta packaging, are usually designed as packaging

Lages to throw away after a single use. Such packaging units

are either closed securely and must be opened by tearing-

ing, cutting or piercing with a view to removing their con

held or provided with a known screw closure. To the first category belong, for example, packaging for beverages such as milk, fruit juices, and so on, as well as sachets containing refills for sprinkle condiments. A typical example of packaging of the second category, with a screw closure, are tubes for toothpaste, produced

cosmetics, and so on.

Packaging units of the first type cannot be reclosed after opening. This may be of secondary importance in the case of typical refill packaging the entire contents of which are simply decanted to refill a container. On the other hand, everywhere where, at periodic intervals, portions

relatively small or relatively large of the whole con-

Since the packaging unit must be removed, there is a need for a tight seal in order to eliminate the known drawbacks of untimely emptying and uncontrolled flow. Containers such as tubes or bottles provided with a screw closure have the disadvantage that at least two separate parts must be manufactured, which must be connected together before or after filling the container. In addition to the additional work that this represents, this way of proceeding contains a certain risk of bacterial contamination, which must be able to be excluded in particular in the case where the container is used in the

drug sector.

The aim of the present invention is therefore to create a pourer on a container with which the aforementioned drawbacks do not

not happen.

According to the invention, one obtains. this result by the fact that the closure part can be used to close the discharge part tight to gases and liquids and with clamping and that means are provided for this purpose on at least one of said

parts.

According to a particularly advantageous embodiment, the closure part is connected, before the first opening of the pourer, by a point intended for breaking, with a low wall thickness, at the end opposite to that opening into the container of the part. spill; According to another advantageous characteristic, the closure part has closure means which, in order to close the pourer, cover the discharge part on a part at the bottom.

less than its length.

The pourer according to the invention, made in one piece and

gas and liquid tight, particularly suitable for sterilization

lization, pasteurization or for fillings under condi-

aseptic treatments. It can be used advantageously on containers of any type, such as sachets, tubes, bottles or tetrahedral packages. The unopened state of

pourer is immediately recognizable on new packaging.

The buyer thus has a guarantee for the perfect hygienic condition of the contents. Other characteristics and advantages of the invention

will emerge more clearly from the following description of

several non-limiting exemplary embodiments, as well as accompanying drawings, in which:

- Figure 1 is the elevation of a first embodiment

stationation of the pourer according to the invention, before the first opening; - Figure 2 is a section of the pourer according to Figure 1 after its reclosing;

- Figure 3 is a sectional view of a second embodiment

sation of a pourer, before your first opening; -

- Figure 4 is a top view of the pourer according to Figure 3; and - Figure 5 is an elevation of a third mode of

making a pourer, before the first opening.

A first embodiment of the pourer 1 according to the invention is shown in Figure I by an elevation. The pourer 1, made in one piece, preferably of a thermoplastic synthetic material, comprises a pouring part 2 and a closing part 3. The two parts are connected.

together in a gas-tight and liquid-tight manner. The tubu- part

Spill area 2 has, in the region of one of its ends, namely its open end 6, a flare 16 which is intended for connection with a container, for example by welding or gluing. According to other embodiments, not shown,

it is perfectly conceivable to conform the flaring 18 itself.

even in a container. The closure part 3 is disposed on the end 7 of the discharge part 2, that is to say on this opposite to the open end. The point of connection of the two parts is made as a point intended for breakage during manufacture, in the form of an area where the material has a very low wall thickness, so that the part of

closure 3 can be easily detached from the overflow part

sement 2 when opening the pourer for the first time. The closure part 3 is essentially a plug in the form of a hollow cylinder closed on one side, the outer wall or skirt 19 of which has notches 20, extending in the longitudinal direction of the

part of the discharge and evenly distributed over the peri-

pheria, in order to have a good grip for gripping and rotating the closure part 3. A closure means 4, having a

cavity 8 which is also closed on one side, is arranged inside

of the closing part 3 of hollow cylindrical shape, essentially concentrically with the skirt 19. The cavity 8 has an internal thread 9 which, after the closing part 3 has been detached from the discharge part 2, can be brought into engagement with a corresponding thread 10 on the outer side of this

last to close the discharge opening created by the puller

ment at the end 7.

Figure 2 shows the pourer according to Figure 1 in the closed state. The closure part 3 covers, via the wall of its cavity 8, a portion of the discharge part 2 adjacent to the end 7. A sealing lip 15 of frustoconical shape is provided at the closed end of the cavity 8. The lip 15 penetrates

into the opening of the discharge part 2 to seal the end

mite 7 in the closed state. After opening the pourer 1 for the first time, the

closing part 3 can be screwed back onto the discharge part

ment 2 and be unscrewed as many times as desired. Thanks to its tubular shape, the discharge part 2 allows the removal

metered from the contents of the container.

Figures 3 and 4 show another embodiment

preferred embodiment of a pourer 1. Figure 3 shows a section of the pourer 1 before the first opening and Figure 2 is a corresponding top view. Parts having the same functions as parts of the pourer described in Figures 1 and 2 bear the same references. The main differences between this second

execution of a pourer and the first execution described above

ment are due to the fact that this pourer has a bayonet seal instead of a screw closure and that the closure part 3 has, instead of a plug of hollow cylindrical shape and closed on one side, two opposing fins 21 for gripping and rotation. Pourer 1, made from a single

ture 3 which are connected together by a point or zone 5 intended for breaking. The closure part 3 comprises a cylindrical rod 26 defining a concentric cavity 8 closed on one side. The inner wall of the cavity 8 has two opposing grooves 11 which are

oriented essentially in the direction of the length of the pourer.

The grooves are accessible from the open end of the cavity 8 and they extend at least over a portion adjacent to this end. Each of the grooves 11 has an angled inner end which extends a distance corresponding at least to the width of the groove, approximately in the direction of the circumference, preferably with a slight inclination towards the bottom.

that the closing part 3 has been torn from the overflow part

sement 2, they can be engaged in the grooves 11 and produce a snap-fit effect, after pressing down

is lying. This pourer can also be closed and opened as many times as desired after tearing or detaching by

rotation of the closing part 3 during the first opening

ture. The fins 21 are formed by four tangentially oriented tabs 22, extending approximately over the length of the cylindrical rod 26 and directed obliquely outwards,

their end portions 23 are joined together.

FIG. 3 shows a third embodiment of the pourer according to the invention. As in the embodiments described above, this pourer 1 also consists of a tubular discharge part 2 and a closing part 3 having closure means 4. The two parts 2, 3 are again connected to each other, tightly against gases and liquids, by a point 5 intended for rupture and formed by a zone of low wall thickness of the material. Unlike executions

described in the foregoing, this embodiment has the particular

larity that the closure means 4 - following the first opening of the pourer 1 by the detachment by rotation of the closure part 3 can be introduced into the cavity 16 of the discharge part 2. In the example shown, the closure means 4 are made in the form of a plug 17, one end of which is connected to a gripping and rotation portion 24 and the other end of which carries sealing rings 25 in

and the cavity 16 of the discharge part 2 could con-

hold a corresponding internal thread. It is also possible, in all executions, that the flaring 18 to

end 6 opening into the container of the discharge part

ment 2, is connected in a sealed manner, by welding for example, to a container manufactured separately, or that this flare 18 constitutes

itself a container.
