Description
METHOD AND DEVICE FOR PACKAGING A FOOD PRODUCT, SUCH AS A CANDY, AS WELL AS A PACKAGED CANDY
The invention relates to a method for packaging food product, such as a candy, wherein a film is formed into a substantially tubular envelope around the product, which envelope extends beyond the product at both ends . The film may for example be a plastic film, aluminium foil, paper, or a combination thereof. The term "candy" as used herein is understood to include sweets, toffees, acid drops, bonbons, chocolate confectionery, candy bars, mini candy bars and other small delicacies. The term "candy" is furthermore to be interpreted as "one or more candies", since it is also possible for more than one candy to be contained in one package. Also other food products, such as sausages can be packaged using the method of the invention. The term "tubular" is furthermore not to be interpreted only as "cylindrical", also envelopes of square, rectangular or other cross- section are called tubular in this connection. The shape of the envelope is generally determined by the shape of the candy.
A method of this kind is disclosed in the published European patent application EP 0 837 010. With this prior art method the candy wrapper is closed by twisting the envelope at some distance from the two ends of the envelope, thus forming a twist-wrap that the consumer will be able to recognize.
One drawback of this prior art method is the complexity of the operation of twisting the envelope. The package must be gripped at three places thereby, viz. in the centre and near both ends, and subsequently the two ends must be rotated with respect to the central part. This
is a factor that slows down the production process when large amounts of candies are being produced. Furthermore, the apparatus that carries out this operation is complex and susceptible to malfunction. Moreover, in practice this operation leads to a large amount of rejects, since candies and/or wrappers are damaged thereby.
It is an object of the invention to provide a method and a device for packaging a food product which is less complex, takes up less time and wherein the amount of rejects is smaller. It is another object of the invention to provide a device for packaging a food product that is cheaper and less susceptible to malfunction.
In order to accomplish those objectives, closing means squeeze the envelope together in substantially radially inward direction at some distance from the ends of the envelope. The closing means thereby exert forces on the tubular envelope, such that the circumference thereof is constricted in the direction of the central axis of the tube, with the envelope necessarily crumpling up. Preferably the tubular envelope is not twisted about its longitudinal axis at the location where said squeezing together takes place, because this is a superfluous operation, which is not necessary in order to close the product and/or making the candy wrapper look like a twist-wrap. It has become apparent that said squeezing together by itself already suffices to close the wrapper and to give the candy the familiar appearance of a "twist-wrap". Preferably the film is plastically deformed upon being squeezed together, so that a durable closure is obtained through which aroma cannot permeate.
Preferably the longitudinal edges of the film are bonded together so as to form the tubular envelope. As a result

radially inward direction at some distance from the ends of the envelope.
The invention furthermore relates to a packaged food product, such as a candy, wherein a film formed into a substantially tubular envelope extends beyond the product at both ends, and wherein the envelope has been squeezed together in substantially radially inward direction at some distance from the ends of the envelope.
The invention will now be explained in more detail by means of an exemplary embodiment which is illustrated in the figures, wherein:
Fig. 1 is a view of a product wrapped by a conventional continuous-flow-wrap packaging line like that shown in part in Fig. 4;
Fig. 2 shows a product in a sheet of film wrap that has been folded around the product, and seamed, to form a tubular shape containing the product, prior to the cutting and sealing of the individual packages in conventional flow-wrap processing;
Fig. 3 shows a product wrapped using a conventional twist-wrap apparatus;
Fig. 4 is a schematic view illustrating a squeeze-wrap apparatus according to the preferred embodiment of the invention, attached to a conventional continuous-flow- wrap packaging line;
Fig. 5 shows a product wrapped using the squeeze-wrap apparatus of the invention;
Fig. 6 shows the squeeze-wrap apparatus of Fig. 4 in
more detail ;
Figs. 7 and 8 show a detail of the squeeze-wrap apparatus of Fig. 6, respectively in an open and closed position; and
Fig. 9 shows a separated part of the squeeze-wrap apparatus of Fig. 6.
The great majority of candy bars are packaged by being wrapped and sealed in a film of wrapping material, on which is printed for example the desired package artwork, logos, ingredients etc. Such wraps are generally formed in the following way. A continuous film of the wrapping material is printed with the artwork and the like (this is generally done by the vendor of the film, not by the food packager) . In the actual packaging process, the products are deposited in the film with proper registration, so that the individual products line up with the artwork on the film. The film is wrapped around the products 12 and sealed in a continuous seam 14 to form a tubular shape 16 (see Fig. 2) . This tube 16 is then cut into parts at the correct locations to produce individual tubular lengths of film, each containing typically one product. Both ends of each of these are then sealed by heat sealing methods or cold-seal adhesive, completing the formation of the familiar wrapped product 20 (see fig. 1) . Commonly, the cutting and the sealing are performed simultaneously, by a mechanism known as a cut-and-seal. These techniques are referred to herein as the conventional "flow-wrap" process.
Another form of wrap for food products, such as candies, involves wrapping individual pieces of the product in a film that is wrapped around the product, again in a tubular fashion, with a twist in each end (see 25, in

When the wrap apparatus 100 of the preferred embodiment is attached to and used with the standard continuous flow-wrap line 50, the operation of the latter is modified in certain respects. First, since it is desired to form a twist-like wrap rather than a flat seam at each end of the package, the placement of adhesive on the film must be adjusted accordingly (the closures that are formed at the ends of the package may be secured in any fashion that proves effective, including the use of either heat-seal or a cold adhesive) . Second, the cut- and-seal 55, the component of the standard continuous flow-wrap line that cuts the tubular shape 16 shown in Fig. 2 into individual portions and then seals the ends, is set only to perform the cutting, and does not seal the ends of the individual packages, although it could do so as an alternative embodiment. Third, the registration and the encoder signals used in the control of the standard line are supplied to the alternative wrap apparatus. According to the preferred embodiment, these are the only control signals that need to be supplied to the wrap apparatus 100 from the standard line.
The wrap apparatus 100, which substantially consists of a rotatable disk system, receives the tubular products, in their individual "product wraps" 24 (i.e. a segment cut from tube 16 and containing the product 22 to be packaged in a single package) , from the upper arbor of the cut-and-seal 55, holds the product 22 and closes both ends of the wrap 24 so as to form the product 30 as shown in Fig. 5: a twist-wrap look-a-like packaging, wherein the end portions 32 of the wrap 24 are however not twisted, but squeezed together in order to form a squeeze 33 at a predetermined distance from the far ends 34 of the wrap 24.

shaped recesses 124. The closing elements 122 thereby move so far inward that the points of the V-shaped recesses just pass each other, as a result of which the envelope 24 is plastically deformed to such an extent that a permanent deformation occurs. The above-described space between the closing elements 122 is sufficiently large, so that envelope 24 will not tear or be cut through.
Then the sliding blocks 110 are moved apart upon further rotation of the transport disc 102, whereby the vacuum of suction opening 116 is released, so that the packaged product 30 will fall from transport disc 102, for example into a receptacle 126.
The present invention has been described in the above by means of a preferred embodiment thereof. Nonetheless, many modifications and variations will now be apparent to those skilled in the art, and the scope of the present invention is therefore not to be limited by the details of the foregoing description.
