Description
TITLE: POURING SPOUT
BACKGROUND OF THE INVENTION
This invention relates to pouring spouts for disposable containers and particularly is related to an inexpensive pouring spout for plastic film type liquid containers.
In recent years, particularly in Canada, the milk industry has successfully marketed their product in plastic bag or film like containers which are inserted in a special holder to provide the structural integrity for pouring of the liquid contents. The common practise is to cut a small hole normally by cutting the corner off the upper area of the bag to provide an outlet point whereby the contents of the container may be dispensed. Such a system works satisfactorily, however it requires a pair of scissors or a razor type instrument for cutting of the plastic bag and often these are not available. One razor type structure has been proposed which is clipped to the holder such that is available when required. However, there remains a need for a simple system for allowing the dispensing of liquid contents from these bag like plastic containers. Often these containers are made of a polyethylene film and are somewhat tear resistant.

12~9839 SUMMARY OF THE INVENTION
A pouring spout for insertion into a liquid storing container according to the present invention comprises a piercing point connected to a tapered section for piercing and subsequent deformation of such container during insertion of said spout into such container, means for limiting the extent to which said spout is inserted into a container including stop means extending beyond said tapered section for contact with such container to limit insertion of said spout and liquid port means intermediate said piercing point and said stop means, said port means being interiorly connected to a pouring funnel to the other side of said stop means.
According to an aspect of the present invention, a spout for a plastic piercable film type liquid container is disclosed which does not require separate tools for allowing the insertion thereof. The spout includes a piercing point connected to a tapered section for initially piercing and subsequently causing partial elastic deformation of such bag during insertion of the spout. Means for limiting the extent to which the spout is inserted into the container is provided and includes stop means defined by a flange portion which extends beyond the tapered section of the piercing point.
lZ1983'3 This flange provides an outwardly step shoulder for limiting insertion. Port means are provided below the outwardly stepped shoulder and are connected to a pouring funnel beyond the shoulder for controlling and directing the flow of liquid from such container. Such a spout allows the liquid contents of the container to pass through the port means through an interior passage past the shoulder to the pouring funnel.
According to an aspect of` the invention, the pouring spout is such that it may be closed by the thumb of a user whereby the contents of the container are not freely dispensable and this allows the contents of the container to remain under pressure during insertion of the spout. As can be appreciated, such bag like containers do not have any structural rigidity and accidental dispensing of the liquid contents could otherwise result during insertion of the spout.
BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENTS
Preferred embodiments of the invention are shown in the drawings wherein:
Figure 1 is a vertical section though the pouring spout;
Figure 2 is a perspective view of the pouring spout according to the present invention;
Figure 3 shows the pouring spout being inserted into a container.
Figure 4, 5 and 6 are partial sections of the pouring spout adjacent the container sealing surfaces of varying design; and ~Z19S~
Figure 7 and 8 are partial sections through a modified pouring spout having a lock ring.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The pouring spout 2 shown in Figures 1 through 3, includes a piercing point 4 at the end of a tapered section 6 which are used to initially pierce the container and subsequently cause the partial plastic deformation of the container adjacent the piercing point during the insertion of the spout. The tapered section during insertion thereof essentially provides a seal with the bag like container due to its smooth peripheral surface. At the end of the tapered section 6, which is preferrably solid, is a cylindrical portion 8 which has at the opposite end to the tapered section a number of sealing area 10, in this case sealing grooves. V grooves, U
shaped grooves, an area of increasing and decreasing width and an undercut area would also work satisfactorily.
Beyond the sealing grooves is an outwardly extending shoulder portion which provides a stop means used during insertion of the spout. A number of fluid ports 14 are provided in the cylindrical portion 8 and are interiorly connected to the central bore 16 of the pouring spout.
This central bore 16 passes through the shoulders 12 and provides a funnel portion 18 which is rapidly outwardly flaired at the open end thereof to provide a flutted end portion 20. The open end 22 of the pouring spout is readily sealed by the thumb of a user and this effectively closes the central bore 16. Therefore, during insertion of the spout, the air trapped in the central bore 16, closed at one end by the user's thumb limits the extent to which the contents of the container can enter the pouring spout. In effect a column of trapped air is provided between the thumb of the user and the contents of -the container. This is important as the contents of the container such as milk bags do not have any substantial structural integrity and insertion of the spout within the container otherwise could result in the accidental dispensing of at least a portion of the contents of the container. By having the open end of the spout closed, the container effectively remains closed until the person removes the thumb from open portion 22.
Initially the piercing point 4 provides a small hole in the wall of the plastic container and the subsequent insertion of the spout into the container deforms the bag in a manner to result in some snap back of the plastic bag once the bag has come to rest immediately under shoulder 12 as generally shown in Figures 1 and 2.
Once the bag has been forced over the tapered section 6, it moves fairly rapidly to the stop shoulders as no further deformation is required. Once it comes to rest at this point, the elastic tendancy of the bag will pull it snuggly against the sealing grooves 10 whereby there is no appreciable leakage of the contents of the bag between the `= ~Z1~839 sealing grooves and the shoulder 12. The deformation caused by insertion of the spout, after piercing of a polyethylene bag, appears to be a plastic deformation with some elastic deformation.
The access ports 14 are provided in the cylindrical section 8 as this is approximately adjacent the upper wall of the plastic bag and will allow essentially all the contents of the bag to be dispensed therethrough. Therefore it is preferrable, although not mandatory, that the tapered section 6 does not include the access ports or at least that a substantial portion of the access ports is provided in the cylindrical section adjacent the stop shoulders.
The flutted end nozzle 20 is rapidly flaired and allows the fingers of the user to grip the exterior surface of this flutted portion while his thumb is closing opening 22. This allows the user to apply pressure to the spout necessary to pierce the bag and force it into the interior of the bag and also provides fairly good control of the spout. It also allows the user to grasp the spout with one hand, thereby allowing the other hand to be -free to steady the bag and contents.
As can be seen from the drawings, the funnel 18 is generally a frustum of a cone and of increasing diameter approaching the open end 22. The shoulder 12 provide a generally perpendicular stop face 11 adjacent the cylindrical portion 8 to assure the spout is not over inserted into the bag like container.
8~3~
Although the spout has been described with respect to plastic bag like containers and in particular, plastic bag type containers commonly used for the packaging of milk, this spout is also useful in other applications, for example for use with waxed milk carton type containers. This spout is particularly useful where the container is of a material which can be easily pierced and can be partially elastically deformed whereby the container provides a snap back type action adjacent the sealing rings of the spout. However, the sealing grooves minimize leakage even if the container is not deformed in this manner.
Figure 4, 5 and 6 show various sealing grooves or undercuts for cooperating with the bag like container and maintain the spout secured in the container in a manner to avoid inadvertent withdrawal. Figure 4 shows a number of "V" shaped grooves 10 which provide an undercut area to allow the bag to snap back and result in the spout retained in the bag and generally sealed therewith.
Intermediate the cylindrical area 8, having access ports 14 and stop shoulder 12, an undercut area 15 may be provided as illustrated in Figures 5 and 6. Area 15 can be used in place of the sealing grooves 10 and similarly allows snap back of the partially elastically deformable container to assist in sealing and retention of the spout in the container. In Figure 5 the undercut area 15 provides a smooth curved surface in cross section whereas area 15 of Figure 6 provides a straight undercut area terminating at the stop shoulder 12.
~Zl~39 A modified pouring spout 2a is shown in Figures 7 and 8. Pouring spout 2a has a sliding lock ring 32 axially movable along cylindrical extension 30 intermediate shoulder 12 and sealing grooves 10. ~top face 11 now cooperates with stop face 36 of lock ring 32 and lower surface 38 of the lock ring limits the extent to which the spout 2a is inserted into a container. A
tapered portion 34 is provided at the lower edge of lock ring 32 for cooperation with sealing grooves 10 to first fold and then pinch the bag container when lock ring 32 is moved downwardly as shown in Figure 8. The bag like container 1 is folded upon itself at point 40 and is subsequently pinch between tapered portion 34 and sealing grooves 10. This lock ring provides a positive sealand locking engagement of the pouring spout 2a and bag like container. It can be appreciated folding of the container may not be necessary.
Although various preferred embodiments of the present invention have been described herein in detail, it will be appreciated by those skilled in the art, that variations may be made thereto without departing from the spirit of the invention or the scope of the appended claims.
