Abstract

An insertable non-drip dispensing tube, for instance for cardboard or plastic cartons, is designed in the form of a tubular body (1) with an insertion point (2) and pouring hole (3) at one end and with an abutment flange/packing (4, 5) for abutment around an insertion point on the container. In order to avoid problems, such as leaking in the insertion hole in the carton, there is provided at or above the pouring holes a movable sealing body (5) which has a mantle (6) which projects radially out from the tubular body and a collar (8) which extends around the inside of the wall of the tubular body. On this collar there are provided flaps (7) at the holes. The interior of the tubular body has lugs or an edge (9) which is provided at the top of the holes, above the collar of the sealing body.

Description

Insertable non-drip dispensing tube

The invention concerns an insertable non-drip dispensing tube, for instance for cardboard or plastic cartons, where the dispensing tube is designed as a tubular body with an insertion point and pouring hole at one end and preferably with an abutment flange/packing for abutment against the carton at the insertion point.

When cartons or cardboard containers for drinks or other liquids, e.g. oil, have to be opened, it is often difficult to make a satisfactory tube piece or dispensing tube and there are also problems with subsequent closing of the opening. In the course .of time, therefore, a number of different solutions have been developed for the design of non-drip dispensing tubes, particularly for cardboard packaging, and amongst these are included insertion bodies, i.e. tubes which are pointed at the end and which are inserted or screwed through the wall of the cardboard container in order to provide a dispensing tube through the tube. This type of insertable dispensing tube has, however, been encumbered with a number of disadvantages which have prevented such devices from being successful in practice. The most serious problem is that leaks are apt to occur in the insertion hole. Other problems are that the dispensing tube is not properly secured in position. There are also designs in which the tubular body is equipped with screw threads for screwing it into the cardboard container, but this causes the edges of the cardboard to be easily torn. This leads in particular to the problem that liquids from the container will seep in and loosen the card¬ board surfaces.

Thus it is an object of the present invention to provide an insertable non-drip dispensing tube in which these problems are substantially avoided and by means of which a dispensing tube can be provided in the wall surface or top surface of a cardboard container in a simple and safe manner and where good sealing properties are obtained in the insertion area, thus substantially avoiding leakage, both inside the cardboard and out of the container. A further object is to provide an insertable non-drip dispensing tube which can be inserted in a secure position with a simple movement, thus enabling the dispensing tube also to be easy for handicapped people to use. People suffering from rheumatism, for example, will often experience difficulty in opening a milk" carton and a dispensing tube of this kind could substantially simplify the process. These objects are achieved with a non-drip dispensing tube of the type described in the introduction, which is characterized by the features in the claims presented.

The invention will now be described in more detail by means of an embodiment which is illustrated in the drawing, which includes:

Fig.l is a non-drip dispensing tube according to the invention, fig. 2 is the non-drip dispensing tube in fig. 1 with its parts illustrated in the position they will assume in an inserted condition, fig. 3 is the method of operation of a non-drip dispensing tube according to the invention in three stages, and fig. 4 shows three different stages which illustrate the method of operation of the invention and with different designs of sealing bodies.

Fig. 1 illustrates a tubular non-drip dispensing tube which is designed according to the invention. The dispensing tube comprises a cylindrical body 1 which ends in a point 2 which will be capable of piercing and being inserted into, e.g., a cardboard container. In the area directly above the point 2 pouring holes 3 are cut which is best illustrated by fig. 2. A short distance above these pouring holes 3 there is provided an abutment flange or ring 4 in the illustrated example. Between the flange 4 and the holes 3 there is provided a movable sealing body which is generally indicated by 5. This sealing body consists of a mantle 6 which projects radially out from the tubular body and on whose underside there are located flaps 7 which in the position in fig. 1 close the holes 3. The flaps 7 are connected with the ring 6 by means of a collar or connection point located on the inside of the tubular body 1 between the mantle 6 and the flaps 7. This connection section or collar-shaped section is indicated by 8 in fig. 3. On the wall of the tubular part 1, in the area directly above the holes there is provided one or more lugs or an edge which is indicated by 9 in fig. 3.

The method of operation for the insertion of the non-drip dispensing tube is illustrated in fig. 3. Fig. 3 shows three versions from left to right, A, B, C, of three stages in the transition between the position illustrated in fig. 1 and the position illustrated in fig. 2, which show the non-drip dispensing tube as it will look when it is inserted and secured in the cardboard container. The cardboard container is indicated in fig. 3 by a line which is denoted by 10. In the initial position the mantle 6 is located in such a manner that upon insertion it will abut against the cardboard container 10. The flaps 7 cover the holes 3. When further downward pressure is applied the lug or edge 9 will push the flaps 7 outwards, while the mantle 6 is pressed tightly against the carton 10. This is illustrated in the middle sketch. The sketch on the right hand side of fig. 3 illustrates the arrangement, in which the mantle 6 abuts sealingly against the carton 10, while the flaps 7 securely grip the underside of the mantle 7. The intermediate collar or connection part 8 will encircle the edge of the cardboard in the insertion area and effect a seal here, as well as against the dispensing tube. In this manner a seal is achieved both against the cardboard and against the dispensing tube while at the same time the dispensing tube is secured in the grip between the parts 6 and 7.

Fig. 4 illustrates in corresponding arrangements A, B, C different design variants. The uppermost series of sketches in fig. 4 illustrates a second design of the sealing body, but the mantle part 6 and the flap part 7 can also be found here. The downward pressure is provided here by an edge 9 instead of a lug. The advantage of this design is a longer sealing area for the sealing body. In the two underlying illustrations, examples are shown of different designs of the sealing body and their pattern of movement. In the bottom part of fig. 4 an example is illustrated corresponding to what is illustrated at the top, but where instead of an edge formed by a graduation in the tube casing, there is again used a lug or a ring element 9 of the same type as in fig. 3.

It should be understood that many modifications will be possible within the scope of the invention. In fig. 1, e.g., the internal sealing collar lies pressed down on the flap part. If the holes 3 extend all the way to the flange 4, the collar can be located in the edge of the mantle 6. The dispensing tube according to the invention may be used everywhere a tube shall be inserted in a wall or surface. The tube may be combined with a drain cock, a hose or other equipment.
