The material ( 16) may consist exclusively of a single layer of monoaxially oriented polypropylene film. The tab portions (30) may be formed in an end seal (22) so that material tears in a longitudinal direction of the package. The package may be a flow wrapped package.
Description
Technical field
The present invention relates to packing, and especially, but not exclusively, relate to for food and the packing of confectionary product more specifically.
Background technology
It is known being packaged in food product (such as the confectionary product of chocolate bar and other snacks types) in the packing that the section by flexible material forms.Described material has the inside face towards described food product, and outside face.Can print on described outside face, perhaps provide information in other mode to the customer.In some techniques, described material is supplied as the part of continuous volume or film.
A kind of known packing configuration is commonly called and wraps up in continuously bag (flow wrap) packing.Use and wrap up in continuously the such packing of bag method production, wherein the film of material is supplied with the form of volume, with several products of packing in basically continuous process.Described method is suitable for wrapping up in wraps the product of rigidity substantially, and described product comprises the product of piece shape substantially, such as chocolate or other confectionery bars etc.Yet described method can be modified to pack difform product, perhaps packs the less product of placed side by side one stacking or an array.
In wrapping up in continuously the bag method, described material is fed through machine, described machine is successively around each product or the folding described material of each piled products, in order to make relative vertical edge surface opposite contact and be combined together to form vertical back of the body envelope (fin seal).Described material is crumpled to form the transverse end hermetically-sealed construction at described product or stacking arbitrary end, and described material is cut separates each packing with the remainder from described film.Can use adhesives to form described hermetically-sealed construction with the relative surface in conjunction with described material, perhaps by described material being fused together to form the hermetically-sealed construction of welding.There is the technology of some known hermetically-sealed constructions for generation of welding, comprises heat seal and ultrasonic sealing.When this method of described materials'use was used to packaging product, described material often is called as wrapped up in packaging material, is wrapped in around described product because described material wraps up in.
Use to form, fill and seal (" FFS ") operation to produce the configuration of bag or pouch type, flexible package also can be formed by the section of flexible material.Such packing often is used to pack flowable product (flowable product), such as liquid and powder, perhaps be used for comprising some less product objects, such as: appetizing snacks, nut, dried fruit, little biscuit, crispbread, matrix sugar piller, peppermint candy, matrix sugar, hard boiling boil sweet food, candy, chocolate, taffy etc.In the FFS operation, the end of the continuous film of material is folded and sealed to be limited to a chamber that end is unlimited.The bag that part forms separates and is filled with product through the end that it is opened from the remainder of described material.The described end of opening is sealed to form complete packing subsequently.Described operation can be as known in the art like that vertically or on even keel fill.Before described bag was closed, described pouch chamber can be by gas (for example, N
2Or CO
2) rush.Bag or the packing of pouch type also can use two sections of material or more multistage be formed, two sections of described material or more the multistage tegmentum cover and be sealed to be defined for the inner chamber that comprises product.For instance, the packing of bag or pouch type can be placed on by the first paragraph with material on second segment and along three limits described two sections packings that are combined together to form section construction are formed.Product is with being introduced into by open end, and described opening is sealed subsequently.
The flexible package of the type that above relates to from various manufacture of materials is known, and described material comprises polymeric material, metallic paper and paper.Usually, described material will be the laminated material with two-layer or more multi-layered different materials.For the packing confectionary product, laminated material commonly used comprises the internal layer of paper and the skin of metallic paper (normally aluminium foil).Yet other materials is used, and comprises polymeric material, and described polymeric material can comprise thermoplastic material, for instance, and such as polyethylene terephthalate (PET).The type that depends on the material of use, known packing can be basically gas and moisture impermeable.Yet, to use for some food and confectionery, the packing of isolated sealing does not meet expectation.
The problem that known flexible package has is that the material that uses is typically very firm.This makes and opens described packing is difficult, because described material is not easy to tear in check mode.In order to assist the customer can use packaged product, usually way be in described material or on provide and tear guiding (tear guide), describedly tear guiding and assist the customer to tear packing along the line of being scheduled to.
A kind of known form of tearing guiding comprises independent material webs, and described band is attached to the inside face of packing.Described band is made by the material firmer than described packing, and an end of described band is exposed on the packing of completing, so that described end can be caught and pull to tear described packing along the line of described band by the user.It is disadvantageous using independent tear-open strip, because described tear-open strip requires make and store extra assembly (being described band), and applies the described additional processing step of taking described packing to.When forming from material webs in being packaged in continuous process (such as adopting continuous packet wrapping), as the part of packaging process, material webs often is applied to described material.Yet in order to apply described band, machine must be with remarkable lower than the otherwise speed operation of obtained maximum speed.When described band during being applied in a lateral direction of described material, especially like this.This has reduced the efficient of packaging process and has therefore caused increasing cost.
In order to overcome these shortcomings, to tear guiding be known to serve as to form one or more line of weakness in packing.Line of weakness can form by means of boring a hole, and described perforation extends through described packing, but to be not suitable for product be perishable situation for this, because seal-packed integraty has been lost.Replacedly, groove can be formed, and described groove only partly passes through the thickness of described material.When described packing are laminated material, the line of weakness that only extends through one deck or some layers is provided so that at least one deck to be left be that the complete integraty to keep packing before opening is known.This configuration is not always satisfactory, is that complete one or more layers may still be difficult to tear in check mode because be left.
Target of the present invention is to provide a kind of improved packing, and described packing overcomes or alleviates at least the problems referred to above.

Described material 16 is folded and sealed to limit the chamber that fully encases described product around described product.The relative side zones of described material 16 is combined together, and inside face is to inside face, and to form vertical back of the body envelope 18, described vertical back of the body envelope 18 is extended along the back 20 of described packing.The end margin district of the relative end that extends beyond described chocolate of described material 16 forms transverse end hermetically-sealed construction 22,24 at arbitrary end of described product in known manner so that aspectant relation is combined together.
In the present embodiment, described hermetically-sealed construction is formed by using cold seal adhesive 26 that the relative marginarium of described material is combined, to produce the hermetically-sealed construction that can be stripped from out.Yet described hermetically-sealed construction can use the adhesives of other types or by using any known method (such as thermal welding or ultrasonic welding) that the hermetically-sealed construction that described material fuses together to form welding is produced.
Described material 16 is to have the flexible material that directivity is torn characteristic.That is to say that described material trends towards preferentially tearing in one direction, so that in case tear on preferred direction and beginning, described tearing just will trend towards on preferred direction continuing in the mode of straight line basically.In the embodiment of an indefiniteness, described material only is comprised of uniaxial orientation polypropylene (OPP) film of simple layer.The uniaxial orientation polypropylene screen has the intensity of tearing of reduction on the direction of orientation, in case and therefore will trend towards tearing beginning, upwards preferentially tear the party.In the embodiment of other indefiniteness, described material 16 is laminar structures, and described laminar structure comprises the skin of polyethylene terephthalate (PET), directed plastic film (such as, Terolen(RTM)) internal layer has aluminium foil layer between skin and internal layer.Other materials that are fit to can be used, and condition is that selecteed material has directivity and tears characteristic.Can print on described material 16 in common mode, and described material 16 can stand surface treatment, condition is that described material 16 keeps its directivity and tears characteristic.
When forming packing, described material 16 is directed, so that described material 16 will on the longitudinal direction of the packing 14 of completing, that is to say on the direction that is substantially normal to transverse end hermetically-sealed construction 22,24 directions and preferentially tear.This is fed on the direction of described machine from described volume at described film typically, and this often is called as machine direction and indicates with arrow A in Fig. 5 in this area.
Be formed in transverse end hermetically-sealed construction 22 one of tab district 30.Described tab district 30 is parts of described end hermetically-sealed construction 22, is combined together to form the hermetically-sealed construction on the internal range 34 at described hermetically-sealed construction only in the relative district of material 16 described in described tab district 30.This can be seen in Fig. 3 best, and wherein shaded area 34 indicates for form the scope of the cold hermetically-sealed construction of hermetically-sealed construction in described tab district.Within described tab district 30 but the remainder in the relative district of the extraneous material of described inner sealing not in conjunction with and form separable tab part 32, described tab part 32 can be pulled open to begin tearing of described material by the user.In the remainder of described end hermetically-sealed construction 22, the relative district of material is basically combined together in common mode on whole their longitudinal extent.
In order to unpack 14, the customer catches described separable tab part 32 and it is pulled open.This either side in described tab district has begun tearing of material.Because the directivity of described material is torn characteristic, described section of tearing along described packing continues in the mode of straight line substantially as specified by the dotted line 40 in Fig. 1.Result is the formation of vertical tear-open strip 42 as shown in Figure 3 and Figure 4, and described tear-open strip has the width substantially the same with described tab district.The customer can only tear a surface of described packing as shown, perhaps can pull two described separable tab parts 32 from the main body of described packing so that tear simultaneously the two sides of described packing.
When whole end hermetically-sealed construction 22 uses strippable cold seal adhesives to be formed, make it more difficult for situation about comparing the relative district of the material that will be pulled open within described tab district in the larger degree of depth of the outer hermetically-sealed construction in described tab district 30.By suitable design, can arrange when described tab district 32 is pulled open, the hermetically-sealed construction within described tab part 30 will be tending towards peeling away, and tearing of described material has precedence over the whole hermetically-sealed construction that is pulled open.
The outer end 36 of described separable tab part 32 is projected into outside the outermost end 38 of remainder of described end hermetically-sealed construction 22.Described tab part 32 is identified and caught to this assisting user.The notch (not shown) also can be formed to help initial tearing at the either side of described tab outshot partly in described end hermetically-sealed construction.
As common way, by means of district or the groove 12b of the prolongation that reduces thickness, chocolate bar 12 is divided into some discontinuous separable section 12a, and described section 12a is aligned to row and column.As be illustrated in Fig. 3, described tab district 30 can with the district of the prolongation that reduces thickness in one align.This makes the user can be in the situation that the residue packing that does not contact described the either side by the catching described tear-open strip all or part of the section of a row section or certain-length separately.
Fig. 5 illustrates the section of the film 16 that is used to form described packing 14.Described film comprises some packings section or wraps up in packaging material 42, these packing sections or wrap up in packaging material 42 and be illustrated with chain dotted line 44 separately, and described chain dotted line 44 indicates that described film is where cut separates each packing with the remainder from described film successively.Cold seal adhesive 26 is applied to the inner face of each packing section to form vertical end hermetically-sealed construction 18 and transverse end hermetically-sealed construction 22,24 with the pattern of frame shape.Each frame shape seal pattern comprises that two side parts 46,48 and two ends divide 50,52, when described material was folded around described product, described side part 46,48 formed the longitudinal sealing structure, described end divides 50,52 to form described transverse end hermetically-sealed construction 22,24.Be the district 54 of wrapping up in packaging material in described frame shape seal pattern, do not have cold seal adhesive to be applied in described district 54, and in the packing 14 of completing, described district 54 encases described product or a plurality of product.
In order to form described tab district 30, do not have cold seal adhesive to be applied in two rectangular areas 56,57, described rectangular area 56,57 is in a described end that forms described transverse end hermetically-sealed construction 22 divides 50.When described material 16 was folded around described chocolate bar 12, described regional 56,57 toward each other so that the material in these districts was not together and form separable tab part 32 when described end hermetically-sealed construction 22 is produced.The outer end of described tab part 32 reaches in the present embodiment outside the outer end of remainder of described hermetically-sealed construction 22 therein, described regional 56,57 extend on the general position of line 44, separate a packing section along the described film of described line 44 is cut with the remainder from described film.When each wraps up in the packaging material segmentation when separated from remaining film, described film is cut along described line 44 on the main portion of the width of described film, but described cutting carries out producing the outshot of described tab part 32 around the first half (as shown) of described rectangular area 56,57.Described regional 56,57 by the external margin setting towards described hermetically-sealed construction 22, and to stay the continuous internal range of the cold hermetically-sealed construction that extends across described material, therefore described packing is intactly sealed before opening.
Fig. 6 illustrates rotating knife 60, and as the packaging process of part, described rotating knife 60 can be used to separate packing from remaining film.Described cutter 60 has blade 62, except two rectangle parts 64, described blade 62 is mainly straight, described rectangle part 64 is suitable for around described regional 56,57 first half cutting does not have cold hermetically-sealed construction to be applied to described film to form the outshot of described tab part 32 in the described first half.Described cutter 60 as shown in Figure 6 will produce the straight limit of described end hermetically-sealed construction 22,24.Yet described blade can be shaped to produce different edge contours.For instance, Fig. 7 illustrates the interchangeable embodiment of rotating knife 60, and wherein blade 66 is shaped to produce the wavy limit of described end hermetically-sealed construction.To be understood that, outstanding tab part must not be rectangle, and can be formed various shape, such as heart.
Fig. 8 illustrates the configuration of interchangeable tab, and wherein separable tab part 32 is not projected into outside the external edge of remainder of described hermetically-sealed construction 22.On the contrary, in this embodiment, notch 68 is formed in the external edge of the hermetically-sealed construction 22 on the either side in described tab district 30.Described notch 68 extends internally basically until the scope of the inner sealing in described tab district 30.The exterior section in the relative district of the material 16 between not combined described notch is separable and forms described tab part 32.
Configuration is easy to open according to packing according to the present invention, and is simple for manufacturing and has cost-benefit.Do not deposit such demand, namely tear guiding to provide using tear-open strip or form line of weakness on the inside face at material in some prior art arrangement on material.In the dispensable while of line of weakness, if expectation, groove may be provided on the inside face of material to help further to limit tear line.
The present invention is not restricted to the application that the packing of bag type is wrapped up in in above-described embodiment disclosed employing continuously, but can be applied to the packing that any suitable flexible material forms, described flexible material has directivity and tears characteristic by the described material of orientation so that being orthogonal to preferentially to tear on the direction of hermetically-sealed construction, and the tab district that is used for initially tearing in described hermetically-sealed construction is formed.It is strippable that the not every hermetically-sealed construction that is used to form packing all needs, although at least the described hermetically-sealed construction in described tab district be strippable be necessary.
Fig. 9 and Figure 10 illustrate the second embodiment of the present invention, and wherein packing 114 is the forms that are called Quad type bag or pouch.Described packing is formed by the section of flexible material 116 in a conventional manner, and is closed on the top by means of top 170, is combined together to form the transverse sealing structure on the relative surface of material 116 described in described top 170.Described top comprises inside top district 172 and exterior top district 174.Described inside top district and exterior top district are separated by line of weakness 176, and described line of weakness 176 is extended across described top, so that described exterior top district 174 can be removed by tearing along described line of weakness.
Within the main portion in described inside top district 172, cold seal adhesive 126(is used as specified by the shade of tiltedly ruling in the relative surface of described material 116) combined together in strippable mode, although other strippable seal arrangement also can be used, such as strippable welding.Hermetically-sealed construction in described exterior top district 174 can be also strippable hermetically-sealed construction, and perhaps described hermetically-sealed construction can be the sealed-for-life structure.Therefore, in described exterior top district 174, the relative surface of described material can be used permanent (that is, not peelable) adhesives or by the welding combination.Aperture 178 is provided in described exterior top district, can suspend in midair from hook for the purpose of showing by means of the described packing in described aperture 178.
Described line of weakness 176 forms by means of perforation line and extends across described packing straight line except a zone, described line of weakness 176 outside (making progress as shown) stretches out to limit tab district 130 in described zone, and described tab district 130 extends to outside the external edge of remainder in described inside top district 172.Do not have cold hermetically-sealed construction 126 to be applied to material within described tab district 130, so that when described top 170 is formed, described material relative surperficial not together.In this embodiment, described tab district 30 is being semi-round in shape, but described tab district can be any suitable shape.In as directed embodiment, only the relative district of the material in the described tab district on the general position that is arranged in described line of weakness 176 130 is not together.Yet, wherein do not have uncombined zone of cold hermetically-sealed construction 126 to extend internally to finite quantity.This will cause the configuration in the embodiment formerly, and wherein the relative district of the material within described tab district is only sealed on than the little internal range of the remainder in described inside top district 172.This can help to make the described tab part 132 of separation to be more prone to begin to tear.Same with previous embodiment, little otch or notch can be provided at the either side of described tab part 132 help to start tear.
In order to unpack, at first the user removes described exterior top district 174 by tearing along described line of weakness 176.As shown in figure 10, along with exterior top is removed, described packing relies on the district's 172 maintenance sealings of described inside top.Stretch out and form separable tab part 132 in the relative district of not together material within described tab district 130 external edge of top seal structure 172 internally, and described tab part 132 can be caught by the user and be pulled open to begin in a longitudinal direction to tear described material on the either side of described tab part 132.Described material 116 is directed so that described material 116 is preferentially torn on the longitudinal direction of described packing, described tearing as from the top to bottom as shown, in a single day begun so that tear, as specified in the dotted line 140 in Figure 10, described tearing continues in the mode of straight line basically trending towards in a longitudinal direction.
In interchangeable embodiment, packing 114 can be manufactured to does not have removable exterior top district 174, so that when manufactured, described packing will be similar to packing shown in Figure 10 114.Bag or the pouch of similar type also can be formed by one or more section of the flexible material that links together by means of the hermetically-sealed construction that limits the chamber according to the present invention.In this case, at least one in the section of material should have directivity tear characteristic and be directed so that when with described hermetically-sealed construction in a tab part that is associated 132 when being pulled, preferentially tear on the direction of expecting for described section.
