Benefits of technology

The present invention aims to provide a closure lid for food products that can be easily and securely closed and opened without the need for additional adhesive application or heat sealing. The closure lid can be used for packaging materials like ice-cream cones or tubs, and provides a more attractive and playful packaging solution for consumers. The closure lid includes a flange member that can securely hold the lid onto the packaging by simply tilting it between a position of being in tight and flush contact with the inner or outer wall of the packaging and a position where it is distanced from the packaging wall. The flange member has slits or slits evenly distributed over its entire circumference to allow for easy removal of the lid without any additional easy-to-open features. The closure lid can be easily and securely opened and closed without any additional tools or effort. The flange member is in tight and contact with the inner or outer wall of the packaging when the closure lid is in its closed state, and it is distanced from the packaging wall when the closure lid is in its open state, allowing for easy removal of the lid without any additional easy-to-open features.

Problems solved by technology

However, paper or cardboard sleeves lack the shape memory provided by the aluminum in the usual composite sleeves, and cannot be crimped down for holding the lid in the usual way.
Further, the lids being glued or heat sealed into the opening of the packaging require a laborious and complex and thus cost-wasting manufacturing process to provide the lid onto the packaging.
In addition, lids being glued or sealed to the opening cannot be easily removed from the packaging once the consumer wants to consume the product.
Such lids thus call for an easy-to-open feature which must be provided in or on the packaging thus further increasing the complexity of the packaging and manufacturing steps.
Furthermore, the conventional crimped or glued lids are not always easy to open.

Embodiment Construction

[0028]FIGS. 1 and 2 show perspective side views of a packaging 1 having a closure lid 20 according to a first and second embodiment of the invention.

[0029]The packaging 1 may comprise a conical sleeve 10 (only the upper part of which is shown in FIGS. 1 and 2) which preferably consists of a paper sheet rolled into a cone. Alternatively, the packaging 1 may comprise a cup 11 (as shown in FIGS. 1 and 2) preferably having the shape of a cylinder or a truncated cone and being made of paper or cardboard. Other materials can also be used. The lid can for example be used with plastic cups or with cone sleeves made from virtually any material. The packaging 1 preferably has a circular cross-section, but it can also have a polygonal cross section (e.g., square or equilateral triangle), provided the panel sizes are equal all around the packaging.

[0030]The material of the packaging 1 is not limited to the materials mentioned above, but can be made of any (preferably flexible) material like pap...

Abstract

The invention relates to a closure lid (20) for a packaging (1) for food products like frozen confectionery, such as ice-cream cups or ice-cream cone sleeves, comprising a plate-shaped centre member (21), and a circumferential non-continuous flange member (22) designed to be selectively in full contact with an inner wall (13) or an outer wall (14) of the packaging (1) and extending essentially in a right angle from the circumference of the plate-shaped centre member (21), wherein the lid (20) is designed such that the plate-shaped centre member (21) can only assume a convex or a concave configuration, and can be manually transferred between the said configurations, and wherein said transfer translates into a change of the angular position of the flange member (22) relative to the plane defined by the circumferential edge (23) of the plate-shaped centre member (21). The invention also relates to a packaging (1) comprising the closure lid and to a packaged frozen confectionery product.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a closure lid for a packaging for non-food or food products like frozen confectionery, such as ice-cream cups or ice-cream cone sleeves, to a packaging comprising such a closure lid, and to a packaged frozen confectionery product.BACKGROUND OF THE INVENTION[0002]Frozen confectionery products are often packaged in individual portions. Common examples are ice-cream cones and also ice-cream cups or tubs. Ice-cream cones comprising a wafer and an ice cream filling are typically wrapped in a cone-shaped sleeve which is commonly made of a paper and aluminum foil laminate substrate rolled into a cone shape with a tip at one end and an opening on the other end. Ice-cream tubs are also commonly made of a cardboard or paper and aluminum foil laminate substrate having a substantially cylindrical or frustum shape and having an opening at one end while being closed at the other end by a base member fixed to the packaging wall. The alum...
