Definitions
- This invention is concerned with a food container and in particular to such a container for snacks or light meals, the container serving not only to package the food but also as the dish from which the meal is eaten.
- Containers for snack foods are normally made out of plastics coated carton board and suffer from two problems.
- the first problem is to provide adequate protection for the contents until use while allowing easy access to the contents.
- the second problem is that after heating of the food the container can be uncomfortably hot to hold or handle.
- the present invention is a food container comprising a body and a lid, the lid being provided with an inwardly tapering peripheral skirt and the body being provided with peripheral walls having a resiliently variable outward inclination, the walls being movable inwardly to allow the skirt to pass down outside the walls and being resiliently expansible outwardly behind the skirt to lock the lid in position.
- the body 10 of the container is made from a sheet of plastics coated carton board, the plastics used for the coating being for example a polyester, polyethylene or polypropylene.
- the plastics used for the coating being for example a polyester, polyethylene or polypropylene.
- Each corner of the flat sheet of carton board is provided with four score lines in the general shape of a 'W' so that when the sheet is folded at the score lines upstanding walls 12 are provided surrounding a base area 14.
- the folded score lines 16a to 16d are visible in the upper left hand corner 16 of the body.
- the walls 12 are not at right angles to the base but are inclined outwardly, the angle of inclination being resiliently variable about a mean figure i.e. the walls can be held in any position between the horizontal and the vertical but in the absence of any applied force will return to an intermediate position at say forty five degrees to the horizontal.
- the lid 18 comprises an upper portion 20 with a surrounding peripheral skirt 22 and is formed from a blank of plastics coated carton board cut, folded and secured, in this embodiment by glue, in the desired shape.
- the peripheral skirt 22 is not vertical but as seen in the drawing is inwardly tapered, the angle of taper being less than the angle of inclination of the walls in the intermediate position.
- the dimensions of the lid are such that the skirt 22 can be fitted over the walls 12 only after the walls have been flexed inwardly to a near vertical position, but when this has been achieved the lid can move easily down until the tops of the walls 12 engage the underside of the portion 20. In this position when the walls are released they will tend to return by natural resilience to their intermediate position and in so doing will expand outwardly behind the skirt 22 to lock the lid in position as indicated in Fig. 2.
- each tab consists of a depending portion 26 which can be glued to a wall 12 when the lid is applied to the body, the portion 26 being attached to the rest of the skirt by frangible lines of weakness 28.
- a cutout 30 is provided in the skirt to facilitate breaking of the frangible lines 28 by for example a thumb.
- the frangible lines 28 are broken and the lid can then be removed, the walls moving resiliently inwardly to allow the skirt to pass upwardly past them and expose the contents of the container.
- the lid can then be inverted as shown in Fig. 3 to provide a stand for the body of the container, the bottom of the container being spaced from the portion 20 of the lid thus insulating the bottom of the container.
