Device for placing products in sealable containers while maintaining the integrity of the seal
First Claim
1. An apparatus for reducing the contamination attendant to the placement of a given product into a container having a sealing flange about its upper, open end, comprising:
- a first belt adapted to move a plurality of said containers in a longitudinal, spaced relation;
a filling means disposed above said first belt and adapted to place a product in said container;
a second belt disposed above said first belt and situated in longitudinal, coordinated alignment therewith, said second belt carrying a plurality of barrier members having substantially planar cross-sections where said member are adapted to be situated in closely spaced relation above said containers and below said filling means, where said barries are provided with an appropriately spaced aperture therethrough to allow for the downward passage of said products into said containers; and
means to automatically remove contaminants derived from said product from said barrier members as said members are carried along the second belt.

Abstract
A filing system which prevents the contamination of a container'"'"'s sealing surface during the system'"'"'s filling procedure is disclosed. A first endless belt is used to convey a succession of containers below a second endless belt. The first and second endless belts travel synronously and in the same direction. A similar succession of shields is attached to the second endless belt. As the two belts converge, the shields separately protrude into and extend over the open end of the laterally traveling containers. The shields prevent product or other contaminants from depositing on the containers'"'"' sealing surfaces as the containers are filled. Drip guards positioned on the downstream portion of the second endless belt collect drippage from each shield as it is removed from its seal protecting position within each container. The first and second endless belts are sanitized on every revolution to further prevent container contamination.

7. An apparatus for substantially reducing the contamination of the sealing surface of a container having a sealing flange about its upper, open end, comprising:
-
a first and a second endless belt disposed one above the other in longitudinal and operative alignment where said lower belt is adapted to carry said containers in a substantially continuous spaced relation; means to ensure alignment between the upper and lower belts, said means including a series of protrusions disposed on the lower belt receivable in oversized apertures formed in the upper belt; an automatic food dispensing apparatus disposed above said lower belt such that a given product may be placed in said tray; said upper belt adapted to carry a series of shield members having substantially planar cross-sections where said members are configured to securely fit above said containers during the dispensing of said product therein, where said shield members are provided with apertures to allow for the passage of said products therethrough, said shield members also provided with a distending lip which extends below the sealing flange of said container during the dispensing of said product into said container. - View Dependent Claims (8)

9. An apparatus for filling material into containers which have a sealing flange around their upper open end, comprising:
a conveyor system including (a) a lower endless belt including a laterally traveling upper section adapted to support a plurality of said containers in spaced relation along the upper section; (b) an upper endless belt including a laterally traveling lower section adapted to travel above and synchronously with the upper section of the lower belt with the containers positioned vertically between the two sections; (c) a plurality of shield members having substantially planar cross-sections which are mounted along and extending outward from the upper belt and spaced along the upper belt such that one such shield is positioned above and travels synchronously with each said container as the container travels on the upper section of the lower belt, each shield configured to enter the upper open end of its respective container in closely spaced relation with said upper open end so as to shield the flange around the upper open end from material within the container; and a filling member configured to deposit material in each container through its respective shield when the shield is positioned within the open end of the containers.

10. A conveyer system for filling containers which have an open upper end surrounded by a sealing flange, which comprises:
-
a first endless belt having a plurality of receptacles spaced along its length and shaped to include a laterally disposed upper section, where said first belt defines an upstream and downstream end, each receptacle configured to receive and support said container by its sealing flange when the receptacles are traveling with said upper section; a second endless belt positioned above the first endless belt and shaped to include a laterally disposed lower section spaced above and aligned with said upper section of said first belt where said second belt also defines an upstream and downstream end; both said belts, including said upper and lower sections, adapted to be driven in synchronism; a plurality of substantially planar shield members mounted in spaced relation along the second belt and projecting outward from the second belt, said shield members spaced along the second belt and configured such that successive shield members enter the open upper ends of successive containers at the upstream ends of said upper and lower section, exit the open upper ends at the downstream ends of said upper and lower section, and shield the sealing flanges of the containers from material within the containers when projecting within the containers. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. Apparatus for filling containers which have an open upper end and a sealing surface around the upper sealing end, comprising:
-
a first, laterally disposed conveyor adapted to support a plurality of such containers in spaced relation along a direction of travel of the conveyor with the open ends of the containers facing up; a second laterally disposed conveyor positioned above and aligned with first conveyor and adapted to travel in synchronism with the first conveyor; a plurality of sleeve-like shield members having substantially planar cross-sections where said members depend from the second conveyor and spaced along the second conveyor such that the longitudinal axes of successive sleeve-like shield members center above successive containers on the first conveyor when both conveyor travel in synchronism, each sleeve-like shield member configured to fit within the open end of its respective container and to shield the upper end surface of the container from material within the container; each sleeve-like shield member further configured to enable a fill conduit to deposit material through the sleeve-like shield member into the container.
