Definitions
- the present invention concerns resealable packaging for sliced delicatessen products, such as e.g. sliced sandwich filling or topping, comprising a trough and a sealing plastic film.
- the route taken by food products from the producer to the consumer is surrounded by many risks and requirements.
- the packaging is therefore an important part of the product's design.
- the packaging should protect against various degradation processes, chemical, biological and climatic effects and not least mechanical damage. It should perform during manufacture, during transport and during handling in storage, shops and the home.
- the packaging must also live up to a series of environmental requirements, and the norms and laws of various markets.
- the traditional vacuum packaging is a packaging which does not contain anything but the product itself. It does not contain air or any other gas.
- the so-called "wallet” packaging is a plastic bag which is sealed at both ends and then folded together, often in a triple-fold, and is fastened with a sticker or a piece of tape.
- the third type which is becoming more and more common, comprises a plastic trough which is covered by a removable plastic film. In the two latter types, the food product is often packaged with a gas which provides an oxygen-free environment.
- the disadvantage with the above packaging types is that, once the packaging has first been opened, it cannot be sealed again in a satisfactory manner.
- the packaging must be wrapped in yet another sealable packaging, e.g. a plastic bag or a container with a lid.
- the product can be transferred to a new sealable packaging.
- the aim of the present invention is to produce a packaging which can be resealed an unlimited number of times after the long-term sealing has been broken.
- the food product can be stored in its original packaging without drying out or losing its freshness until it is consumed.
- a packaging has now been provided with comprises a removable lid which can be used while storing the food product, and which can then easily be removed when the product is to be served.
- the packaging comprises a trough which is sealed with a plastic film, under which a loose lid is arranged.
- the lid has a cupped form which fits on the inside of the trough under the plastic film.
- the sealing plastic film is pulled completely off the edges of the trough.
- the removable curved lid is revealed, which has a shape such that it fits the inside of the trough and simultaneously covers the food product to be stored.
- the lower edges of the lid lie with their lower edges against the inside/bottom of the trough and thereby completely cover the food product.
- the lid When the product is to be served, the lid is removed from the trough by suitably gripping two recesses in the lid's upper side which are shaped to provide a good grip to lift the lid. The lid is then lifted up out of the trough. The product can now be served directly from the trough without further handling of the food product or the inside of the trough.
- the food product can be re-covered by the lid by gripping the two recesses on the upper side of the lid and placing the lid in the trough.
- the lower edges of the lid are formed with a flange projecting outwards from the lower edge, which - when the lid is in place in the trough - preferably lie on a inwardly-curved ledge which is provided along the lower portion of the walls, on the inside of the trough. In this way, the flange of the lid and the ledge form a seal against the surroundings.
- the width of the lid flange is somewhat greater in the corners than along the edges.
- a preferred embodiment of the packaging which comprises a rigid container 100 which can have the form of a beaker, a trough, a box, a tray or the like.
- the container 100 preferably has a square, rectangular or polygonal form, but can even be round or oval and is made of plastic, cardboard, polystyrene, laminated plastic, laminated cardboard or similar material which is approved for the storage of food products.
- the container 100 is made of a material selected from the group comprising polypropylene, polyethylene, polyester, polystyrene, or mixtures of these materials.
- the container can also be laminated with material such as plastic or aluminium.
- the space in the container 100 in which the food product is stored is defined by the container's side walls 101, a bottom 102 and the upper edge of the side walls 103.
- the food product which is preferably manufactured such that it can be served directly (e.g. sliced, sliced and folded or diced) from the container 100 is intended to be placed on the bottom 102.
- An inward bend is located along the lower portion of the side walls 101, above the bottom 102, which forms a ledge 104 extending along the entire inside of the container 100.
- a rigid lid 105 is arranged within the container 100.
- the lid can be made of plastic, cardboard, plastic-coated cardboard, polystyrene or similar material which is approved for the storage of food products (see above).
- the lid 105 is made of a flexible and supple plastic material such as e.g. polypropylene, polyethylene, polyester, polystyrene, or a mixture of these materials.
- the lid 105 has the same shape (i.e. square, rectangular, polygonal, round or oval) as the container 100, but the size is adjusted so that it fits in the space defined by the inside of the side walls 101, the ledge 104 and the upper edge 103 of the container 100.
- An outwardly-projecting flange 106 extends from the lower edge of the lid 105.
- the flange 206 of the lid lies on the ledge 204 along the side walls 201 in the container 100 ( Figure 2a), and in this way, seals the space under the lid in which the food product is contained.
- the flange 106 is somewhat wider than along the straight edges, which means that - when the lid is set in place - the flange is bent upwards in the corners due to friction against the wall of the container 100.
- the upwardly-bent flange in the corners of the lid form locking projections 207 when they press resiliently against the inner walls of the container and thereby keep the lid 205 in place within the container 100 ( Figure 2b).
- the upper side of the lid 106 is formed with two recesses 108 which are designed to be readily gripped with two or more fingers so as to lift the lid 105 out of or into the container 100.
- the plastic in the recesses 108 can optionally be roughened to offer a better grip.
- the upper side of the lid can be optionally decorated with a relief.
- the container 100 has an edge flange 109 around its opening which extends along the entire circumference of the opening.
- a plastic film 110 is glued or heat-sealed to this edge flange 109, which covers the opening of the container 100.
- the plastic film 110 is formed of a material which is approved for the storage of food products, e.g. polyethylene, cellophane. After heat-sealing with the plastic film 110, the packaging is gas-impermeable, which means that the food product is protected against exchange of air with the surroundings. This provides extended lifetime of the product after packaging.
- Figure 3 shows how the covering plastic film 310 can be provided with a corner which has not been heat-sealed entirely out to the edge. This makes opening of the packaging easier.
- the plastic in one corner of the container 100 can be provided with a special slitted bias, which also makes it easier to remove the plastic film 310.
- Figure 4 shows an alternative embodiment in which the ledge along the side walls 401 of the container 100 comprises instead a bulge in the form of a shelf or a ridge 404.
- Figure 5 shows another alternative embodiment of the present invention.
- the side walls 501 have a recess 504 along the entire inside of the container, near the bottom 502.
- the lid is pressed down along the side walls 501 on the inside of the container 100, so that the lid flange 506 reaches the recess 504 so as to lie on the bottom 502 of the container 100.
- the locking projections 507 on the corners of the lid press against the inside of the walls in the corners of the container near the bottom 502 and the lid is prevented from coming loose by the flange 506 being locked in the recess 504 and - at the same time - the locking projections 507 press against the corners in the container 100.
- the embodiments presented in Figures 4 and 5 are advantageously used when the container 100 has a round or oval form in which there are no corners in the inside of the container against which the locking projections 407, 507 can press against.
- the lid flange 406/407, 506/507 is pressed down along the walls on the inside of the container, past the ridge 404 or down to the recess 504.
- Flange 406/407, 506/507 presses against the walls of the container, along the entire inside of the container and thereby locks the lid 405, 505 against the inside of the container 100.
- the seal which is formed between the flange 106, 206, 406, 506 of the lid and the ledge 104, 204, or the bottom 402, 502 is not a gas-impermeable seal.
- the seal corresponds to covering a food dish or bowl which has no lid with a plastic film such as Gladpack®. Similarly to plastic films, the lid protects the covered product from dirt, drying-out and contact when it is placed in the packaging according to the invention.
- the food product is placed on the bottom 103 of the container 100.
- the lid 105 is applied inside the container so that the edge flange 106 of the lid lies on the ledge 104, at the same time as the flange 106 in the corner of the lid squeezes the lid tightly in the correct position by pressing against the corners of the container 100.
- the plastic film 110 which completely covers the opening of the container is welded and pressed tightly against the edge flange 109 of the container so that a gas-tight packaging is created.
- the inner lid 105 has a height such that it lies level with the upper edge of the trough, which means that the covering plastic film 110 easily presses the lid 105 downwards and thereby holds the lid 105 and the underlying food product in place.
