Abstract

A container having a container body that can have a circumference/perimeter variation along a vertical axis, a bottom surface, and a container opening having a top surface; an axially oriented shrink wrap sleeve covering a portion of the body of the container having a circumference variation and the container opening; the shrink wrap sleeve having a pair of generally vertical perforations descending from the shrink wrap top edge towards a circumferential perforation ring oriented below the container opening. The axially oriented shrink wrap sleeve covering a portion of the container body circumference variation has a greater or lesser circumference at at least one point between the perforation ring and the bottom edge of the shrink wrap.

Claims

1. A container containing a liquid concentrate and configured for squeezing to dispense a jet of the liquid concentrate, the container comprising:

a container body having a circumference/perimeter variation along a vertical axis, a bottom surface, and a flip top cap having a moveable hinged part having a top surface, the container body having a pair of sidewalls extending between front and rear surfaces, the sidewalls converging toward the flip top cap, the front and rear surfaces each having a greater maximum width than the sidewalls;

an axially oriented shrink wrap sleeve covering a portion of the body of the container having a circumference variation and a portion of the hinged part, and a bottom edge of the shrink wrap sleeve being spaced from the bottom surface;

the shrink wrap sleeve having a pair of generally vertical perforations descending from a shrink wrap top edge towards a circumferential perforation ring oriented below the moveable hinged part, the circumferential perforation ring extending between the pair of generally vertical perforations;

wherein the shrink wrap sleeve covering a portion of the container body circumference variation has one of a smaller or larger circumference at at least one point between the circumferential perforation ring and the bottom edge as compared to adjacent portions both above and below the circumference variation in order to prevent the shrink wrap sleeve from slipping off the container after removal of the portion thereof extending between the circumferential perforation ring and the top edge; and

a shoulderless span of the exterior of the container extending from immediately below the moveable hinged part to an opposite side of the circumferential perforation ring, the shoulderless span including a continuously increasing circumference extending away from the moveable hinged part and toward the bottom of the container.

2. The container of claim 1, wherein the axially oriented shrink wrap sleeve covering a portion of the container body circumference variation has a greater circumference at at least one point between the shrink wrap circumferential perforation ring and the bottom edge.

3. The container of claim 1, wherein the axially oriented shrink wrap sleeve covering a portion of the container body circumference variation has a smaller circumference at at least one point between the circumferential perforation ring and the bottom edge.

4. The container of claim 1, wherein the generally vertical perforations descending from the shrink wrap top edge are progressively closer together as they approach the circumferential perforation ring.

5. The container of claim 1, wherein the generally vertical perforations descending from the shrink wrap top edge terminate at the circumferential ring.

6. The container of claim 1, wherein the generally vertical perforations descending from the shrink wrap top edge terminate at a space of about two perforations above the circumferential perforation ring.

7. The container of claim 4, wherein the generally vertical perforations descending from the shrink wrap top edge begin with an initial perforation cut, followed by relatively smaller perforation cuts, configured so that when the shrink wrap is applied to the container body, each of the larger cuts forming a ‘

V’

shape at a top of each vertical perforation to define tab between the vertical perforations.

8. The container of claim 1, wherein the front and rear surfaces of the container body are generally planar, and a seal of the shrink wrap sleeve is vertically oriented along an edge of the rear surface.

9. The container of claim 1, wherein the shrink wrap sleeve is a polymer selected from the list consisting of:

polyethylene terephthalate (PET), a copolymerized polyethylene terephthalate (PETG), polyethylene terephthalate glycol (PETG LV), polyvinyl chloride (PVC), polypropylene (PP), and polyethylene (PE).

10. The container of claim 1, wherein the shrink wrap sleeve has a shrinkage rate of about 75 percent to about 85 percent.

11. The container of claim 1, wherein the shrink wrap sleeve has a shrinkage ratio of about 2:

1.

12. The container of claim 1 further comprising a seam for the flip top cap, said seam being covered by the shrink wrap sleeve, said shrink wrap sleeve being at least partly opaque.

13. The container of claim 12, wherein the flip top cap has a recession portion disposed immediately below the moveable hinged part and above the circumferential perforation ring.

14. The container of claim 12, wherein the seam is between the circumferential perforation ring and the bottom edge so that the shrink sleeve assists in maintaining the flip top cap on the container body after removal of the portion of the shrink sleeve extending between the circumferential perforation ring and the top edge.

15. The container of claim 1, wherein the shrink sleeve terminates a height on the container so that no puckering occurs.

16. The container of claim 1, wherein the increasing circumference is predominately in the sidewalls as compared to the front and rear surfaces.

17. The container of claim 16, wherein the pair of generally vertical perforations of the shrink sleeve is disposed adjacent one of the sidewalls.

18. The container of claim 1, wherein the shrink wrap sleeve has no legal information above the circumferential perforation ring.

19. The container of claim 1, wherein the top edge of the shrink wrap sleeve terminates at a height allowing the top surface to remain exposed.
