Product multi-pack
View Patent ↗A product multi-pack is provided with a plurality of elongate product containers. The containers each include a bottom, an open top that is closed by a cap and a wall extending there between. The wall includes a label having a front portion extending about a limited section of the wall circumference. A carton is provided that is sized to display the plurality of product containers. A locator web is provided that is formed of a thin sheet of plastic having a plurality of spaced apart apertures. The apertures are sized to be at least partially elastically deformed when installed over the caps of the product containers. Additionally, the locator web provides frictional resistance to rotation of the product containers, which enables the containers to be positioned and held in place relative to the carton open face so that the label front portions are visible.
1. A system for orienting and preparing labeled product containers for a product multi-pack, comprising;
a first conveyance means for conveying the labeled product containers;
a feed station coupled to said first conveyance means for controlling the flow of the labeled product containers along first said conveyance means;
a web application station for continuously applying a web to the labeled product containers, said web formed from a thin elastic polymer and comprising a plurality of apertures, transverse slits and perforations;
a rotation sensor for measuring the rotational position of the labeled product containers using at least one indicator on said labeled product containers to measure said rotational position;
a feed sensor for determining the longitudinal position of the labeled product containers;
an alignment station for selectively rotating the labeled product containers during continuous flow of the labeled product containers;
a cutting station for cutting said web at a predetermined length creating a predetermined set of labeled product containers joined by said web on the labeled product containers;
a transfer station for transferring the labeled product containers to a carton;
a carton erecting station for assembling said carton;
a second conveyance means to convey the cartons from said erecting station to said transfer station;
a controller that receives signals from said rotation sensor and said feed sensor for tracking and directing the position of each said labeled product container.
2. The system of claim 1 wherein said transfer station comprises a transverse dial that receives the product containers in a first position and rotates to a second position whereupon the product containers are ejected.
3. The system of claim 1 wherein said web application station comprises:
a drive sprocket positioned adjacent to said first conveyor for feeding said web; and
an applicator mechanism for installing said web on the product containers.
4. The system of claim 1 wherein the diameter of said apertures of said web are less than the diameter of the cap of the product container.
5. The system of claim 1 wherein said web comprises perforations for cooperation with said drive sprocket.
6. The system of claim 1 wherein said alignment station comprises first and second drive members.
7. The system of claim 6 wherein said first and second drive members are positioned opposite each other and transverse to said first conveyance means.
8. The system of claim 7 wherein said first and second drive members each comprise a rotating belt, wherein said rotating belts frictionally engage opposing walls of the product containers.
9. The system of claim 7 wherein said first and second rotating belts contact up to three product containers simultaneously.
10. The system of claim 6 wherein said controller independently controls the speed of said first and second drive members to rotate the product containers.
11. The system of claim 1 wherein said rotation sensor measures the position of said indicator relative to a pre-determined co-ordinate system.
12. The system of claim 11 wherein said pre-determined co-ordinate system is a 360 degree polar co-ordinate system centered about each product container.
13. The system of claim 1 wherein said indicator is located on the cap of the product container.
14. The system of claim 1 wherein said indicator is located on the label of said product container.
15. The system of claim 1 wherein said indicator is an indentation on the bottom of the product container.
16. The system of claim 1 wherein said controller controls said alignment station to rotate the product containers.
