Description

The sealed package and corresponding technology and the equipment that are used for food
Technical field
The present invention relates to be used for the sealed package (therefore being called " fully enclosed " package) of food, for example be used for confectionary products.
Background technology
In the packing of food, need consider different needs, at first, need to guarantee that product keeps not changing after packing in the long as far as possible time.
In order to obtain above-mentioned purpose,,, product is packaged in usually in the sealed package that is referred to as " packing flows " type for small-sized food (for example chocolate, preserved fruit, praline etc.) in known following period of time.This packing technique imagination is the spool since a sheet material, and this sheet material is by the vertical packaging product of former, thus a continuous portion of tubular center of formation packing, and this part is sealed by article one longitudinal sealing line.Will carry out packaged products and in portion of tubular center, move ahead, and the integral body that is therefore obtained stands the action of one or more sealing platform.Here, portion of tubular center carries out smooth, produces single package thereby weld and shear in the separated region between the continuous product.An example of this technology is described among document EP-A-0957043.
Even the consideration on function (for example is laid on one side, relating to the fact that the zone that sealing purpose is played a crucial role can be formed in the overlapped zone of the horizontal welding end of the packing that flows and vertically welding or potted line), flowing, there is no question about as an industrial result for packing.Therefore when such packing be used for purpose be with one more the packing of traditional type interrelate product (for example certain confectionary products) time, be not enough far away, the Traditional Packing that for example is used for preserved fruit has the product that is contained in a packing, thereby one or two end distortions of this packing form counter of fantail (counter of fantail distortion packing).
Owing to this reason, the packing that purpose is to reproduce described more traditional forms has been proposed in the scheme of prior art.
A scheme of the type is for example described in document WO-A-02/22445: the single length of the pars intermedia of a mobile package-type is around the packing of product, thereby form the structure of a tubulose, thereby bear extruding formation plication region to a certain extent in the radial direction at one, this zone is similar to the counter of fantail distortion end of a preserved fruit packing of traditional type.
The major defect of this type of package is should be subjected to accurately enforcement in the zone of radial compression with respect to the sealing function of external environment.Yet even a kind of packing are sought help from evidence, this material can be subjected to bearing partial melting at least in the zone of radial compression, and is quite appropriate with respect to effective leak free degree of external environment.This fact can be understood fully, if in aforesaid zone, the packing that are compressed in the vertical form fold in a kind of complete uncontrolled mode.Therefore, fold or protrusion form in the mode of completely random, stay open easily between these folds, perhaps open after through short time, thereby form the passage that is connected with external environment.
The scheme that can obtain an outstanding sealing property with respect to external environment condition has been described in document EP-A-0591742 and EP-A-0790184.Yet under these two kinds of situations, the packing in the scheme comprises the element of two used sheet materials.
Summary of the invention

Description of drawings
Now, also present invention is described with reference to the accompanying drawings will only to pass through nonrestrictive example, wherein:
Fig. 1 to Fig. 5 has shown the consecutive steps of a technology, and this technological design is used to provide one according to packing of the present invention; And
Fig. 6 is the lateral plan of corresponding apparatus.
The specific embodiment
Below the embodiment of shown example relate to a kind of production that is used for the packing of product 1, this product for example is made up of a kind of confectionary products, for example difform chocolate, preserved fruit, praline etc.
Especially, have a dressing on the product, for example add the fibert slag, broken coconut, the dressing of the white sweet cake of scrambled egg etc.
Under any circumstance, size, shape, the natural and/or distinctive feature of product (simple or synthetic) all can not constitute a constraint element of the present invention.
Product 1 is designed to be packaged in the packing, and this packing is made up of a package sheet material 2, and this package sheet material 2 is made by a kind of sheet package material that is widely used in the confectionary products packing.
Therefore this is a kind of sheeting of can be effectively product and external environment being kept apart.For example, it can be an aluminium foil and/or plastic material.Also can be a kind of " compound " material just in question material, that is to say, a kind of material like this, this material comprises that at least one has formed the exterior ground floor that packing is finished part, and one formed the in-to-in second layer that packing is finished part, and for example this material demonstrates heat sealable performance.
An exemplary of the composite material of this character is a kind of material, and this material outer paillon foil made of aluminum covers a kind of plastic material, and for example polyethylene is formed on the inside face of making.
It should be understood that all that under any circumstance scheme described herein is limited to the special selection of sheet-material package material in no instance, also is not limited to the special technological process that closed/sealed packing itself are adopted.
(emphasize again among the embodiment here, this only is an example), suppose that technology is an element from package sheet material 2, this element for example has a foursquare shape or is similar to square shape, and only has the sheet material of several centimetre lengths on one side at it.
To clearly illustrate more that from the following description in fact the discrete-component of described packing can be limited by a part or the length of a continuous sheet, thereby the discrete-component that forms packing is extracted and cut off to described discrete-component out from a spool.
On the element of package sheet material 2 shown in Figure 1, on about center that the object that need pack or product 1 lie in element.
In the accompanying drawings, described product occurs with the main body form of a parallelepiped shape; It should be understood, however, that product 1 can be Any shape.
In the next procedure of the process that forms packing, thereby the element of package sheet material 2 forms around product 1 parcel:
A folding part 20, this folding part 20 are enclosed in the inside to product 1 effectively; And
Two sides 21, these two faces extend from folding part 20 and are arranged on the opposed faces of product 1 (being end face and bottom surface in graphic direction).
As seen in Figure 3, can understand easily that package sheet material wraps up around product 1 in so a kind of mode, no matter the i.e. shape of product 1 forms one with pocket or the envelope of side 21 as the guide surface of a reality.
In fact, two sides 21 are parallel to each other basically, and are separated out by a thickness or a distance highly that corresponds essentially to product 1.
In another step subsequently of technology, as shown in Figure 4, two sides are connected to each other together by a sealing lines 3.
Potted line 3 connects two sides of package sheet material according to a path around product 1.Therefore the path has an overall arc usually, that is to say, and C shape pattern, the end in path is positioned on the position of folding part 20, the verified effect that can play the product 1 of sealing packaging in described folding part, thus do not need to form connection lead.
In order to form potted line 3, can be by means of many methods of widespread use in packaging industry, in particular for the method for packaged food.
Therefore, potted line 3 can, for example, by heat-sealing, cold envelope is used welding material or is not used welding material to seal, ultrasonic welding, laser welding or, may seal by a simple mold pressing operation.
For the path of potted line 3, though be essentially the envelope apperance with regard to product 1, it also is possible adopting other different selection.
The present test shows of doing of the application, basically a continuous arc patterns is the optimal selection in path, thereby without any any overlapping (that is to say, need not overlappingly surpass two-layer above packing) of the protuberance of tip and/or packing or fold.Such zone for example can be to obtain and this zone can keep flat under the state of stress concentration by two slack-free connections of adjacent straight line, and this stress concentration may weaken the sealing of potted line.
Complete operation further, the packing shown in Fig. 4 is finished by forming one or two counter of fantails distortion packing departments 4, thereby makes the single-piece representative type outward appearance of packing as candy wrapping.This result can obtain (in known manner) by the longitudinal end or the end of distortion packing, perhaps can obtain the method for a counter of fantail distortion by means of other.
It should be understood that the formation of described counter of fantail distortion packing department can not produce adverse influence to the sealing property of potted line 3.In fact, this is to obtain by two sides 21 that connect sheet material package sheet material 2 when two sides 21 remain essentially on the same plane.
Therefore the connection between two sides 21 very closely and be continuous, thereby can resist, rather than weaken any possible distortion that packing takes place subsequently.
Refer now to the equipment shown in Fig. 6 of seeing, debatching assembly of Reference numeral 10 expressions, the sheet material of forming package sheet material 2 from this assembly is drawn out of.
From uncoil-stand 10 (being known type), package sheet material 2 is supplied with along a former 12, and this former 12 is supplied with the sheet material that is generally the U-shaped shape that comprises a folding part 20 and side 21 (see figure 3)s.
Similarly, former 12 itself can be an element of a known type.In fact this former 12 is to obtain according to the standard that is widely used in making former, and in a kind of packaging machine of mobile package-type, former is according to a common tubular pattern sealing sheet material.
The characteristic feature of the tubular packing on being formed on flow wrap machines device (perhaps in the scheme described in the WO-A-02/22445) is that tubular packing is by a potted line sealing longitudinally and when having a cross section profile that is essentially annular, the corresponding centre part of the equipment shown in Fig. 6 should be open (referring again to Fig. 3) on the contrary, in this sense, two sides 21 do not link together on corresponding to their positions than distal edge.
Again, the centre part shown in Fig. 3 is represented an improvement that is generally U-shaped, and two sides 21 remain essentially in flat state.As previously mentioned, this fact that is based upon the sealing property on the packing of finishing for obtain by potted line 3 one continuous be important with being connected closely.
Carrying out packaged products 1 towards the zone supply that can guarantee former 12 operations by a conveyer 14, this conveyer 14 for example can be made up of a motor-driven load-transfer device that is widely used on the packaged food equipment.
Described conveyer 14 matches with former 12, thereby product 1 is inserted in the packing that are folded into U-shaped with the spacing distance of regulation, thereby produces a loading stage, and this loading stage is done as a whole by Reference numeral 16 expressions.
Under described situation, (centre part of packing is formed an operation element of this conveyer usually by another conveyer, because this conveyor delivery position thereon product 1 and the centre part of packing) supply with, product is transported on the position corresponding to a sealing platform 18, thereby produces potted line 3 and produce different packages in the banded section of the region generating packing that do not have product on sealing platform 18.
According to a known structure own, thereby sealing platform 18 can be to have the type of up-and-down movement and comprise a base portion or the 18a of anvil portion, and work moving part 18b, this moving part 18b vertical shifting and periodically being reduced under the 18a of anvil portion, thus form potted line 3 and single package is sheared.Because above-mentioned purpose, base portion 18a and/or operation element 18b have the staggered plane that limits potted line 3 paths usually.When the packing technique that adopts was included in heat and/or hypracoustic application, base portion 18a and/or operation element 18b can be associated with heater element and/or ultrasonic generator (do not illustrate especially, can be known type).
Advantageously (at this still according to they self known standard), thereby can set up sealing platform 18 operates, except causing base portion 18a and operation element 18b, perpendicular movement is enclosed in mutually together at the midway location place of package, one " track " also having package to move ahead moves, and described track moves the formation action that causes potted line 3 and takes place under the situation of relative motion not having.
The fixing 18a of anvil portion can have a hollow at least a little end face, thereby guarantees that potted line 3 (packing that constitutes between by mutual osed top 18a of portion and 18b is made) can obtain under the situation of best symmetry.
Usually, sealing unit 18 has shearing elements (not special demonstration that is associated with on it, but be known type), be used to make the continuous strip of package sheet material 2 after potted line 3 forms or in the formation, to be separated, thereby produce single package, for example the packing shown in the C among Fig. 6.
Shaping platform of Reference numeral 20 expressions, in this shaping platform, one or two longitudinal ends of package C are further handled (for example distortion) thereby are formed the fan-shaped afterbody 4 shown in Fig. 5.
Therefore from subsequently further packing as can be seen, the package of having finished is collected in the gathering station 22.
Therefore; it should be understood that; do not have the prejudice to the principle of the invention, by the explanation and the diagram of non-limitative example, the details of realization of the present invention and embodiment can change on a very big degree can not depart from protection scope of the present invention yet with respect to merely.
