A lunchbox with a tilted top edge

Abstract

A lunchbox with an inclined upper edge includes a box body having a base plate and a surrounding wall. A height direction is defined perpendicular to the base plate. The edge of the base plate has a first side and a second side opposite to each other. The surrounding wall is connected to the edge of the base plate and forms an accommodating space with the base plate. An upper edge is formed on the surrounding wall away from the edge of the base plate. The upper edge defines an opening. A first segment and a second segment are formed on both sides of the upper edge corresponding to the first side and the second side, respectively. The height of the first segment in the height direction is lower than that of the second segment in the height direction, so that the upper edge surrounding and defining the opening is inclined from the second segment toward the first segment, thereby making the food more easily visible from the portion of the opening corresponding to the first segment, effectively improving the convenience of eating.

Claims

1. A lunchbox with an inclined upper edge, comprising: a box body having a bottom plate and a peripheral wall; a height direction defined in a direction perpendicular to the bottom plate, the edge of the bottom plate having a first side and a second side opposite to each other; the peripheral wall being connected to the edge of the bottom plate and forming an accommodating space with the bottom plate, an upper edge being formed on the peripheral wall away from the edge of the bottom plate, the upper edge defining an opening around it, the upper edge forming a first segment and a second segment on both sides of the first side and the second side respectively, the height of the first segment in the height direction being lower than the height of the second segment in the height direction, such that the upper edge defining the opening is inclined from the second segment toward the first segment.

2. The lunchbox with an inclined upper edge as described in claim 1, wherein the first side and the second side are parallel to each other; the first segment and the second segment extend in a straight line direction and are parallel to each other.

3. A lunchbox with an inclined upper edge as described in claim 1, wherein the base plate is rectangular; the upper edge is a rolled edge that surrounds and defines the opening.

4. The lunchbox with an inclined upper edge as described in claim 3, comprising a lid, the lid being a light-transmitting plastic cover and including a central portion and a peripheral portion, the peripheral portion being integrally and circumferentially connected to the central portion, and forming an annular groove on the peripheral portion in accordance with the shape of the rolled edge, the annular groove fitting into the rolled edge portion, thereby fixing the lid to the box body and covering the opening.

5. A lunchbox with an inclined upper edge as described in claim 4, wherein the middle portion has a top surface that is parallel to the bottom plate.

6. A lunchbox with an inclined upper edge as described in claim 4, wherein the middle portion has a top surface that is flat and inclined relative to the bottom plate, the top surface being lower in the height direction on one side corresponding to the first segment and higher in the height direction on the other side corresponding to the second segment.
