Detailed description of the invention

With reference to figure 1, there is the first flat surfaces of the outside face by forming structure container and the container blank 2 forming the second flat surfaces of the inside face of structure container is made up of (may the inserting of anti-oxygen layer with such as aluminium foil between substrate and innermost thermoplastic plastic layer) the laminate of point other the outmost and innermost layer comprising paperboard substrate and moisture barrier thermoplastics.The container 4 on pediment top or the carton (showing in fig. 2) that formed from it for packing the liquid of such as milk or fruit juice, and especially for the aseptic packaging of such liquid.

In order to produce container blank 2, one sheet of packing material can pass through in known manner between pair of rolls, its edge around blank cuts material and also forms line of weakness, this line of weakness the blank of the outer surface by forming final container the first flat surfaces and will form the blank of the inner surface of final container both the second flat surfaces on be appreciiable.

Blank 2 is grouped into by four body portion forming panel P1-P4 with the 5th standard seal panel, and they are defined by the line of weakness of the form in line S1, S2, S3 and S4 therebetween.Dignity plate P1 to P4 by further defining in their lower edge in the line of weakness of the form of line S5 to S8, and divides out from row's end cap part P6 to P9 thus.Similarly, the row of honorable plate P1 to P4 by further defining in their upper edge in the line of weakness of the form of line S9 to S11, and divides out from row's top closure panel P10, P11 and a P13 thus.Top closure panel P12 is not separated with from its neighbouring body part P3 directly to inner position by physics line, but there is invisible line of weakness in the boundary between panel P3 and P12, at this place when container 4 constructs from container blank 2, top closure panel P12 will fold relative to honorable plate P3.Panel P10 and P12 is quadrangle, and form point other quadrangle lid panel of the container 4 on pediment top, panel P11 and P13 is also quadrangle simultaneously, but is divided into sub-panel P11a to P11c and the P13a to P13c of three fundamental triangles each via point other tilt line S12, S13, S14 and S15.The row of top closure panel P10 to P13 is defined in their upper edge by row's top closure panels P14 to P17, to form the seal strip 6 (see Fig. 2) of container 4.Anterior, top closure panel P12 is formed with perforation 8 (or alternatively, being reduction ring in the situation of aseptic packaging), and spout fitment of coming down in torrents 10 is applied to this perforation 8 (see Fig. 2).

When container 4 produced by the blank 2 shown from Fig. 1, blank 2 converts container sleeve to, and it has rectangular cross section, and wherein honorable plate P1 to P4 is formed and forms ring around sleeve around the ring of sleeve and lid panel P10 to P13.End cap panel P6 to P9 is folded to form end cap in axle.End cap panel P6 to P9 folding after, these panel sealings in axle to form bottom.Sealing comprises heat panel P6 to P9 and to be pressed together to cause thermoplastic plastic layer to be viscosity to create the bottom sealed.Alternatively, can use other encapsulating method, such as, glue together, heating is by dispensable in this case.After the filling of container 4, form top cover by formation sheet sealing in known manner 6.Then, the flange (see Fig. 2) of spout fitment of coming down in torrents 10 is by being such as attached to the outer surface of top seal sub-panel P12 weakening ultrasonic welding on ring 8.Alternatively, the flange of spout fitment of coming down in torrents 10 can be applied to the inside of sub-panel P12 before filling through the spout that comes down in torrents that hole 8 is outstanding.Container 4 will be suitable in the aseptic of liquid or non-sterile packaging.

With reference to figure 3, laminate packing comprise cardboard substrate 100, the skin 102 of thermoplastic material, the internal layer 104 of thermoplastic material and are arranged in the barrier layere 106 of the such as oxygen barrier layer between the internal layer 104 of cardboard substrate 100 and thermoplastic material.After the formation of container blank 2, the roller of packing process is in-between to can be arranged (compression on the surface of the ply of board 100 of the skin 1025 by thermoplastic plastic and the skin 102 in the face of thermoplastic plastic), to make at least one recessed line 12 in the surface of the material of the outer surface 14 by forming final container, corresponding inner surface 16 is left level and smooth and smooth simultaneously.This obtains by having the desired pattern be made up of one or more press-fit equipment on one of roller by contact outside face 14, and the corresponding position simultaneously on another roller is level and smooth.Like this, recessed line 12 will be visible but invisible on inner surface on outer surface.

Before container blank 2 converts container sleeve to, grasping enhancing substance 18 can deposit and enter (many) recessed line 12, material 18 is comprised in (many) recessed line 12, and does not spill on the outmost surface of outer surface 14.Material can be the form that friction increases material.Like this, friction increase material 18 is retained in the position that it is required most.

In filling machine, with different surfaces frictional behavior container blank (such as when grip element etc. adhere to container outer surface and from that outwardly time situation) will often need the difference of filling machine to adjust, its cause when from film magazine take out blank, load blank in axle, transfer vessel leave axle enter chain bag, in the chain bag throughout filling machine container orientation and finally top seal time filling machine in different performance.The combination that (many) recessed line 12 increases material 18 with the friction be included in (many) recessed line 12 will not have injurious effects in filling machine performance.

It was advantageously flowing material that friction increases material 18 before it is employed, such as high friction ink or varnish.High friction ink or varnish are made up of the acrylic resin of modification, and it shows to obtain picture elastomeric material (relatively very resilient with relatively high flexibility ratio), thus causes nonslip properties.In addition, high friction ink or varnish do not comprise as the known any silicone resin of smoothing preparation or wax.

Friction increases material 18 and can be deposited on (many) during being used in the identical process of the UV print procedure such as carried out at the ink station be separated with other ink of the decoration for container and be recessed in line 12.Because need not wait for that ink becomes dry, it is relatively fast process that ultraviolet (UV) prints.Therefore, friction increase material 18 may be selected to be and solidifies when it is exposed to UV radiation as the ink used in this process.But the additive method of printing container decoration can increase together with material 18 with the friction be applicable to that can select according to this and uses.

Like this, friction increases material 18 and in the application of various degree to have friction and/or frictional belt in various degree, and can not interfere other tactile feature of production process.Fully to be included in (many) recessed line 12 and the processing not interfering another contiguous container blank of contact or sleeve because friction increases material 18, so this heap superimposition contributing to smooth container blank or sleeve is cancelled stacking.

By obtaining such container 4, customer will experience the grasping strengthened on container.Vision may be had and/or physically impaired customer is favourable especially for those.The use of container 4 reduces in the risk spilt of period liquid food content and the risk of the container 4 that drops of coming down in torrents.

(many) recessed line 12 can, with the pattern arrangement specifically expected to obtain best grip characteristics, provide surface to catch vehicle along the tyre surface of the vehicle tyre on the ground of advancing the spitting image of being designed to.Like this, (many) recessed line 12 points out how container 4 should be handled by customer clearly.

Because the inner surface 16 of material is not doped with (many) recessed line 12, it is left the level and smooth and smooth surface that makes and can sterilizes efficiently.Because the ridge not having bacterium and other microorganism cultures wherein to survive after sterilisation in packing or wrinkle, so so level and smooth and smooth inner side surface is desirable for disinfecting process.

The degree of depth of (many) recessed line 12 is preferably less than the half of ply of board thickness, and be most preferably less than 1/4th of ply of board thickness, to guarantee use the material 18 of minimum and there is enough contacts between the skin and material 18 of the finger of customer.

The uncompressed known vessel reservation relative smooth of region as this kind forming the outer surface 14 of (many) recessed line 12.Therefore, (many) recessed line 12 visually and/or in sense of touch for customer describes the favourable manipulation of one or more grasping section 20 for container 4.

The container 4 of Fig. 2 has the lateral body panel P2 with the multiple grasping sections 20 described by multiple (many) recessed line 12.A grasping section 20 is formed by the pattern of the recessed line 12 of basic annular, and another is formed by the pattern of the recessed line 12 of multiple (many) wave.Contrary lateral body panel can be supplied to identical pattern or different patterns, to consider that user points the mode of location during the holding of container 4.The position of (many) on honorable plate P2 recessed line 12 and pattern also can be depending on the size of container 4 and different.The different grasping sections 20 of display do not need to be provided in together, make them independent of shape and the pattern also can each other with any desired.The pattern of recessed line 12 of the basic annular of display is slight inclination relative to level from the joint between lateral body panel P2 and rear body panel P1 to the joint lateral body panel P2 and precursor panel P3.This enables customer obtain naturally grasping of container 4.Divide other contrary lateral body panel P2 and P4 and point other contrary top closure panel P11b and P13b can comprise linear point of weakness 22 further, to point out to customer once where Foldable container is for refuse process/circulation after all liq food content thing turned letter of container 4, or in order to the promotion emptied completely by extruding liquid contents residual arbitrarily and relative high viscosity liquid (such as Yoghourt) from container 4 from folding container 4.To customer, linear point of weakness 22 without grasping section 20, but points out that fold line is substantially for flattening container 4.

The waveform line of recess 12 can be continuous print as display, or they can be interrupted.

Grasping section 20 also can forming region for the concrete printing of manipulation relating to container, this printing can take the form of text and/or image.
