BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a discharging device for a packaging container and more precisely to a discharging device of the docking type. The connection or docking of a packaging container to for instance a hose having an orfice frequently represents a need. Within the medical care, there are consumed a huge amount of poaches of flexible material for nutrition solutions of different types and there is a need for handling such packages in a more rational manner.
Besides, there is a high degree of aseptics necessary when parental nutrition solutions are involved, for instance infusion solutions, etc.
Prior art and background of the invention: The prior art within the field of discharging devices for flexible poaches comprises poaches having specific orfices welded to the poach before filling and sealing, said orfices having tearable closures or needles or other puncturing tools for penetrating a membrane of the closure.
The prior art discharging or docking devices do meet reasonable hygiene and aseptic standards but from a production point of view the known constructions imply higher cost due to an irrational manufacturing procedure needing for instance separate welding of orfice details.
Previously, poaches of the actual type have been manufactured in the traditional manner, i.e. poaches have been manufactured individually from blanks.
The use of a "hose" technic for manufacturing poaches having an aseptic contents is for instance enclosed in Swedish Patent No. 455,044. Such technics, however, makes use of a separate connector member for docking to the interior of the poach.
OBJECTS OF THE INVENTION
The object of the present invention is to provide a packaging container having an integral docking device or discharging device, for instance formed directly from a hose forming procedure, and allowing an aseptic type of docking or assembling to a discharge conduit. The docking device according to the present invention may, with advantage, be used in an application where a product containing package is formed from a filled hose, but of course there are other fields of application.
SUMMARY OF THE INVENTION
Thus, the invention provides a packaging container having a channel formed of a flexible material intended for connecting the interior of the container to a discharging device, for instance a hose having an orfice.
The container is characterized in that the channel is terminated by a grip flap for opening the channel, and the grip flap is such that it exposes a portion of the inside of the channel when opening up the channel.
In a preferred embodiment there is arranged a denotation for initially tearing off the grip flap at the edge region of the channel, said tearing denotation joining a circumferential weakening line cross-wise the channel, and the circumferential denotation defining at least a section projecting from the opened up channel and acting as an entering surface for the discharging device.
In a specific embodiment the channel is terminated by a weakened welding portion and free grip flaps are arranged outside said welded portion.
In still an embodiment the grip flap is arranged as a termination of a tearable end portion of a channel having a curved cross-section.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows a certain type of flexible poach having a tearing arrangement according to the invention,
FIG. 2 is a partial view of a first embodiment of a channel having a grip flap,
FIG. 3 shows the channel in FIG. 2 exposed after the removal of the grip flap,
FIG. 4 shows another embodiment of a channel having a grip flap,
FIG. 5 shows still one more embodiment of a channel and a grip flap,
FIG. 6 shows the channel in FIG. 5 opened up,
FIG. 7 shows one version of a channel having an accompanying grip, and
FIG. 8 shows the channel in FIG. 7 opened up and exposed.
DESCRIPTION OF PREFERRED EMBODIMENTS
The poach 10 in FIG. 1 is a two-sided, alternatively three-sided welded poach. In the first case, there are lateral welds 11, 12 obtained by folding one single planar
