Protective wrap for microwavable container
View Patent ↗A wrap for a microwavable container, such as a cup with a removable lid, the wrap having a separable hinged portion to allow the lid of the container to be removed. The separable portion can then be returned to its original position, and the wrap and enclosed container heated in a microwave oven. During heating, the wrap remains relatively cool to the touch, so that the wrap and container can be removed from the oven by grasping the wrap, without contacting the hot exterior of the container.
1. A protective wrap for a microwavable container having a removable lid, the wrap comprising:
a top wall, a bottom wall, and side walls adapted to surround the container;
the wrap including a remainder portion and a separable portion separable from the remainder portion and pivotable away from the remainder portion about a hinge line formed in the top wall; the remainder portion including a section of the top wall and the searable portion including sections of at least two of the side walls;
the separable portion being so located that when it is pivoted away from the remainder portion, the lid of the container is accessible for removal;
whereby, after the lid of the container has been removed, the separable portion may be pivoted back to its initial position with the container positioned within the wrap.
2. The wrap of claim 1 , wherein the hinge line approximately bisects the top wall.
3. The wrap of claim 2 , wherein the separable portion is separable from the remainder of the wrap along a tear line.
4. The wrap of claim 3 , wherein the tear line extends across a first side wall from the junction of the top wall and the first side wall to the bottom wall, across the bottom wall, and from the bottom wall across a second side wall to the junction of the top wall and the second side wall, opposite the first side wall.
5. The wrap of claim 4 , wherein cutouts are located at the side corners of the wrap, to facilitate grasping of the wrap.
6. The wrap of claim 3 , wherein the tear line is located entirely within the top wall.
7. The wrap of claim 3 , wherein a first side wall comprises a lip extending from one edge of the top wall, and a tear line extends across each of the adjacent side walls from their junction with the top wall to a point adjacent to the bottom edge of the lip.
8. The wrap of claim 1 , wherein the separable portion comprises a section of the wrap divided on a vertical plane, the hinge line extending across the top wall to allow the separable portion to be pivoted upwardly about the hinge line.
9. The wrap of claim 1 , wherein the separable portion is a pivotable lid comprising approximately half a of the top wall.
10. The wrap of claim 9 , wherein the hinge line extends across a corner of the top wall to allow the pivotable lid to be pivoted upwardly about the hinge line.
11. The wrap of claim 9 , wherein the pivotable lid is formed by sections of the top wall and side walls, the pivotable lid having a lip on each of its free edges, the hinge line extending entirely across the top wall to allow the pivotable lid to be pivoted upwardly by about the hinge line.
12. The wrap of claim 1 , including means for retaining the separable portion in its initial position after the lid of the container has been removed.
13. The wrap of claim 12 , wherein the means for retaining comprises frictional engagement between the separable portion and the container.
14. The wrap of claim 12 , wherein the means for retaining comprises an inter-engageable tab and slot.
15. The wrap of claim 1 , wherein the bottom wall comprises two flaps, and means for attaching the two flaps together.
16. The wrap of claim 15 , wherein the means for attaching comprises glue.
17. The wrap of claim 15 , wherein the means for attaching comprises at least one co-engageable tab and slot.
18. The wrap of claim 15 , wherein the means for attaching comprises two tabs on one flap, a locking tab at the free end of that flap, and slots in the other flap engageable with the two tabs and the locking tab.
19. The wrap of claim 1 having four side walls, two of the opposing side walls comprising lips which depend from the edge of the top wall.
20. The wrap of claim 19 , wherein the container is a cup having a circular horizontal cross section, and the top wall is a square.
21. The wrap of claim 1 , having at least one vent in the top wall to permit the escape of steam from the container when heated.
22. The wrap of claim 1 , wherein the wrap is made of a material which will remain substantially cooler to the touch than the exterior of the container when the wrap and container are heated together in a microwave oven.
23. The wrap of claim 22 , wherein the wrap is made of paperboard.
