LID TO COVER AN EGG CONTAINER, SHEET TO ASSEMBLE ONE

LID AND CONTAINER FOR EGG

Technical field of the invention

The present invention is directed to a lid for covering or closing an egg container, to a sheet for assembling said lid and to an egg container with a container and a lid, and more specifically to a lid comprising a plurality of faces and to the at least one tab on at least one of the side faces.

Background of the invention

Containers of different types are known for packaging and transporting fragile articles such as egg trays, which are advantageously used together with lids for said trays. These lids not only have the function of preventing dirt from falling on the eggs, they also serve to protect them from impacts in the same way as the trays on which the eggs rest, and in particular, to allow the stacking of several containers.

In this sense, it is important that the lid materials are resistant enough to allow stacking and protect the eggs from impacts. As most common egg containers are considered disposable, the question arises of how to balance the cost of materials with the strength needed to protect the contents and achieve stable stacking without damaging the eggs.

Typically, egg containers, or egg trays, are made from materials comprising cellulose fiber, such as cardboard, which have limited mechanical strength, while lids are typically made from polymeric materials, which are environmentally friendly. They are less desirable.

Another requirement is that the lid must be firmly attached to the egg container in order to prevent the two parts from separating during transport or shifting when several containers are stacked on the lid. Additionally, from a commercial point of view, the containers, and in particular the lids, must allow consumers to examine the product without having to manipulate or open the container, and once the product is purchased, the lid must offer convenient and convenient access. simple to content.

In addition, some egg containers exhibit undesirable behavior during the packaging process, as the lids are not properly attached to the tray, causing them to move.

Therefore, it seems clear that there is still a lot of room for improvement in egg packaging, and especially for egg container lids.
