DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to an arrangement for portioning viscous material, preferably foodstuff, e.g. ketchup or mustard, from a pack, preferably a plastic bag of flexible material, whereby a portioning means is connectable with the pack so that viscous material can be dispensed therefrom by means of said portioning means, preferably by gripping and compressing an elastic part thereof, whereby said portioning means includes a non-return valve having a valve seat and a valve means cooperating therewith and being adapted to prevent material from flowing back from the portioning means to the pack when said portioning means is compressed for dispensing material therefrom, and whereby the pack is positionable in an outer container so that the portioning means is directed downwards therefrom.
Prior art outer containers of said type are expensive to manufacture and they do not permit quick exchange of empty packs for new such packs. Furthermore, simple retaining devices are lacking, which can be brought to quickly and easily retain the upper end of the portioning means relative to the outer container without the risk for loosening or damaging said portioning means when it is handled manually for dispensing material from the pack.
The object of the present invention has been at first hand to eliminate these problems and this is arrived at by providing the device defined above.
SUMMARY OF THE INVENTION
By means of these characterizing features it is attained that the outer container as well as the retaining device consists of a few easily manufactured members. Furthermore, the measure to place a new pack in the outer container and locking the portioning means in relation thereto, is facilitated. The portioning means can namely be brought to automatically take an exact position relative to the retaining device when the pack is placed in the outer container such that said portioning means can be retained by means of the retaining device by simply closing the outer container. Additionally, the retaining device can protect vital members of the nonreturn valve forming part of the portioning means when said retaining device retains said portioning means such that said members are not damaged during manual handling of the portioning means for dispensing material from the pack.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 schematically illustrates all major components forming part of the arrangement according to the invention located beside each other before assembly thereof;
FIG. 2 with a plan view illustrates an outer container forming part of the arrangement according to the invention and which is open and wherein a pack with a portioning means is located;
FIG. 3 is a section along the line III--III through the arrangement of FIG. 2;
FIG. 4 with a plan view illustrates the arrangement according to the invention, whereby the outer container is closed;
FIG. 5 is a vertical section through a portioning means forming part of the arrangement of the invention;
FIG. 6 is the same section through the portioning means as in FIG. 5, but during suction of material; and
FIG. 7 is the same section through the portioning means as in FIGS. 5 and 6, but during dispensing of material.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The portioning or dispensing device illustrated in the drawings is adapted for portioning or dispensing viscous materials 1, preferably foodstuff such as ketchup or mustard, from a pack 2, preferably a thinwalled plastic bag of flexible material. The pack 2 is positionable, e.g. suspendable at the top, in an outer container 3, which is suspendable or positionable at a location at which dispensing of the viscous material 1 occurs, e.g. in a kiosk, in a snack bar or in a restaurant.
The portioning device has a portioning or dispensing means 4, preferably including a compressible hose 5 of elastic material. This portioning means 4 can be connected with the pack 2 so that viscous material 1 can be dispensed therefrom by means of the portioning means 4.
