Abstract

A method for producing multipacks of containers includes placing adhesive spots on surfaces of the containers. At least two kinds of adhesives are used, both of which plastic melt adhesives that melt as a result of exposure to heat and that develop cohesion after cooling. After placing the adhesive spots, the containers are connected to each other using the adhesive spots so as to form a multipack.

First claim

Having described the invention, and a preferred embodiment thereof, what we claim as new, and secured by Letters Patent is:

1. A method for packaging containers, said method comprising producing multipacks of containers, wherein producing multipacks comprises selecting first and second adhesives that are plastic melt adhesives that melt as a result of exposure to heat and that develop cohesion after cooling, placing adhesive spots on surfaces of containers, wherein said adhesive spots comprise at least said first and second adhesives, and connecting said containers to each other using said adhesive spots, thereby forming said multipack, wherein a first container is at a periphery of said multipack and a second container is at an interior of said multipack, wherein placing adhesive spots on surfaces of containers comprises placing adhesive spots to cause said first container to bond to an adjacent container with a first adhesive strength, and causing said second container to bond to a neighboring container with a second adhesive strength, wherein said first adhesive strength is less than said second adhesive strength.

2. The method of claim 1 , wherein said first and second adhesives have different physical properties.

3. The method of claim 1 , wherein said first and second adhesives have different chemical properties.

4. The method of claim 1 , wherein said adhesive spots have different thicknesses.

5. The method of claim 1 , wherein said adhesive spots have different compositions.

6. The method of claim 1 , wherein said adhesive spots have different spatial extents.

7. The method of any one of claim 1 , wherein each adhesive spot comprises said first and second adhesives.

8. The method of claim 1 , wherein said first and second adhesives define different zones of an adhesive spot selected from said adhesive spots.

9. The method of claim 8 , wherein said different zones adjoin one another.

10. The method of claim 8 , wherein said different zones form an archipelago of zones.

11. The method of claim 8 , wherein said different zones form a preselected configuration.

12. The method of claim 1 , wherein said adhesive spots comprise a first subset and a second subset, wherein adhesive spots of said first subset are made only with said first adhesive and adhesive spots of said second subset are made only with said second adhesive.

13. The method of claim 1 , wherein placing adhesive spots on surfaces of containers comprises placing die spots of adhesive in different vertical positions on a container.

14. The method of claim 1 , wherein placing adhesive spots on surfaces of containers comprises placing die spots of adhesive in different circumferential positions on a container.

15. The method of claim 1 , wherein placing adhesive spots on surfaces of containers comprises placing die spots of adhesive in different radial positions on a container.

16. The method of claim 1 , wherein placing adhesive spots on surfaces of containers comprises placing die spots of adhesive in different axial positions on a container.

17. The method of claim 1 , wherein the said first and second adhesives have different adhesive strengths.

18. The method of claim 1 , wherein the said first and second adhesives have undergone differing preliminary treatments.

19. The method of claim 1 , wherein said multipack is a filmless multipack.

20. The method of claim 1 , wherein placing adhesive spots on surfaces of containers comprises placing said adhesive spots in a manner such that the adhesive strength between containers varies as a function of location of said containers within said multipack.

21. The method of claim 1 , wherein placing adhesive spots on surfaces of containers comprises placing die spots of adhesive in different horizontal positions on a container.

22. A method for packaging containers, said method comprising producing multipacks of containers, wherein producing multipacks comprises selecting first and second adhesives that are plastic melt adhesives that melt as a result of exposure to heat and that develop cohesion after cooling, placing adhesive spots on surfaces of containers, wherein said adhesive spots comprise at least said first and second adhesives, and connecting said containers to each other using said adhesive spots, thereby forming said multipack, wherein said containers are arranged according to rows and columns in said multipack, wherein placing adhesive spots on surfaces of containers comprising placing said adhesive spots in a manner that causes an adhesive strength that connects rows to each other to be different from an adhesive strength that connects columns to each another.
