Definitions

  • This invention relates to a stand-up pack, a method and apparatus for manufacturing such a pack.
  • So-called stand-up packs are known in the packaging and retailing industries as a means of storing and displaying for sale various food and other products that behave like fluids when they are packed.
  • Such products include granular foodstuffs such as pet foods and sweets; powdered products such as flour, sugar, dehydrated food powders, dehydrated beverages such as cocoa powder and baking soda; and liquid products such as soft drinks, flavouring syrups, sauces and some solid foods such as mozzarella cheese that have to be packed in a liquid (water).
  • stand-up packs are gaining acceptance for the storage and display of products that hitherto have been stored in rigid containers. In this category are included herbs, spices, salt, rice and pasta. Large stand- up packs can be produced for storing e.g. animal litter, wild bird seed and domestic cleaning agents such as soap powder and dishwasher powder. Hitherto it has been known to produce a various kinds of stand-up packs using a horizontally extending production line.
  • Figure 1A One example is shown in Figure 1A; the pack having a top seam 10 and left- and right-hand seams 11 and 12.
  • the front and rear panels at their lower ends are bent out as illustrated, to provide stand-up capability.
  • Packs such as those shown in Figure 1A can only be produced on horizontal production lines because it is necessary to form the upper end of the pack as shown in Figure 1 A in an initially open form to permit filling of products into the pack prior to forming of seal 10. If a pack such as shown in Figure 1A were to be manufactured in a vertical machine, the open end would be positioned at an edge of the pack as formed and filling of the pack from above would not be possible. Horizontal machines as are required to form the pack of Figure 1 A suffer disadvantages.
  • FIG. IB A second form of known pack is shown in Figure IB.
  • This pack includes side gussets so a gusset-forming step must be included in the manufacturing process.
  • This pack can be formed on a vertical machine. It has seams 10B, 1 IB and 12B. The presence of seam 1 IB extending vertically along the centre of the rear of the pack limits the kinds of advertising matter that can be printed on the rear face. Moreover any printed matter must be accurately positioned in this region.
  • FIG. 1C A third known form of pack is shown in Figure 1C. This is known in the art as “block bottom” pack. This can also be formed on a vertical machine. It has seams IOC, 11C and 12C.
  • Figure 1A are too light or too fluid in nature to permit the folded bottom of the pack to fill out properly and become a stable support for the pack. This is partly because the folded bottom of the pack of Figure 1A is intended simply to provide extra space in the pack for receipt of products, and consequently its ability to support the pack is limited. Thus, there is a need for a stand-up pack and a method of manufacturing such a pack that obviates the various disadvantages of known packs.
  • a stand-up pack comprising front and rear walls joined at their upper ends and secured one to the other along mutually spaced seams extending between the top and bottom of the pack and a further seam extending across the front of the pack, the front seam being formed between the front wall and a portion of the rear wall, the pack including a base formed from a portion of the rear wall folded forwardly, said forwardly folded portion including the front seam.
  • a pack of this kind has numerous advantages over the prior art. Firstly, the pack can be readily manufactured using a modified vertical form fill and seal machine. This machine takes up much less floor space than a horizontal stand-up pack production machine, and vertical filling of the packs followed by sealing of the packs without further movement thereof (as is possible in vertical form fill and seal machines) means that jolting of liquid products does not occur and consequently the filling of liquid products into stand-up packs can be more readily achieved. It is possible with the packs of the invention to create folded bottoms of virtually any width, thereby advantageously allowing the packs to be made inherently stable. Furthermore, the manufacturing of the folded bottoms of the packs of the invention does not involve the formation of a gusset per se and consequently the manufacturing process to create the packs is quicker.
  • the front face of a pack according to the invention is in a preferred embodiment arranged to be bounded on the vertical side edges and across the horizontal lower edge by seams, with no seam across the top of the pack unless this is specifically desired for presentation purposes. As a result, the appearance of the packs is significantly neater than the prior art packs.
  • the disadvantages associated with the seam 1 IB of the Figure IB pack are obviated.
  • the front and rear walls of the pack are constituted by a single sheet. This feature advantageously minimises the number of seams necessary to create the pack.
  • the joint between the upper ends of the front and rear walls of the pack is or includes a fold. This feature advantageously neatens the appearance of the pack.
  • the mutually spaced seams extend along the respective vertical side edges of the pack when the pack is upright.
  • this feature also improves neatness of the pack.
  • packs in accordance with the invention could be manufactured with the seams spaced from the outer edges of the pack, and of course it is not a pre ⁇ requisite that the seams referred to extend parallel to the edges of the pack.
  • packs according to the invention in which the mutually spaced seams do not extend for the entire distance between the top and bottom of the pack; or in which the mutually spaced seams are stepped, curved or otherwise shaped.
  • the front seam is made between aligned lower ends of the front and rear walls of the pack. This feature confers speed and economy on the manufacture of the packs.
  • the forwardly folded portion of the rear wall is further folded rearwardly whereby to provide a portion of the rear wall adjoining the front wall to constitute the front seam.
  • This feature ensures reliable formation of the front seam.
  • the portion of the rear wall abutting the front wall lies on the underside of the forwardly folded portion when the pack is upright.
  • the underside of the pack includes a dart that tends to fill out as the pack is filled with product.
  • the packs can be supplied flattened down when empty and can be subsequently filled and sealed, with the product being inserted into the packs serving to "inflate" the pack by causing the dart to fill out.
  • a method of manufacturing a pack in particular comprising the steps of, in any suitable order,
  • the filling of the packs can advantageously occur from what becomes a side when the pack is upright.
  • the forming of the transverse, front seam in a direction parallel to the axis of the fill tube shortens the length of the sealing element needed compared with existing vertical form fill and seal machines (since the front seam extends only for the width of the pack when upright) and consequently allows the use of a shorter fill tube.
  • the second and third seams are formed by a sealing element of a form fill and seal machine, the sheet being advanced in the time between the forming of the second and third seams whereby to space the second and third seams one from the other. This feature allows the maximum throughput of the form fill and seal machine to be attained.
  • the second and third seams are formed by a sealing element of the form fill and seal machine, the sealing element being moveable in the direction of feeding of the sheet whereby to permit spacing of the second and third seams.
  • the sealing element is driveable and is capable of gripping the sheet, whereby to advance this sheet on driving of the sealing element and permit spacing of the second and third seams one from another.
  • sealing element as a driving element for the sheet constitutes an advantageously efficient manner of advancing the sheet through the apparatus.
  • the forming of the second and third seams is accomplished by plural sealing elements of the form, fill and seal machine. If the sealing elements are appropriately positioned, the use of plural sealing elements does not slow the throughput of the apparatus.
  • the method includes the further step of filling the pack with goods before the forming of the third seam. Filling at this stage is advantageous because the pack is virtually completely formed and therefore has structural rigidity, yet the pack can still be filled via a large filling aperture constituted by the edges that are intended to form the third seam.
  • the method of the invention may optionally include the further step of securing a portion of the initially double edge portion of the sheet and the remainder of the sheet together, whereby to form a transverse, rear seam on the pack.
  • apparatus for forming a stand-up pack in particular as specified hereinabove or for performing a method in particular as specified hereinabove comprising: an infeed area for sheet material; a drive for feeding sheet material through the apparatus; a folding tool for doubling an edge portion of the sheet material in the apparatus; a folding tool for further doubling the edge portion in the apparatus, whereby to form a double fold along said edge portion; a former for forming the sheet material into an orientation such that one edge portion of the sheet lies adjacent the opposite edge portion of the sheet; a sealer for sealing the adjacent edge portions together whereby to form a front, transverse seam of the pack; a sealer for forming a second seam extending from the front seam in a direction generally transverse thereto; a sealer for forming a third seam extending from the front seam in a direction generally transverse thereto and spaced from the second seam; and a filler for inserting goods into the pack.
  • an apparatus of this kind is used to manufacture the pack or to perform the method of the invention, such apparatus is advantageous since it can readily be constructed as a modified version of e.g. a vertical form, fill and seal machine.
  • a vertical form, fill and seal machine Such a machine is of benefit in the practising of the invention not least because it has a high throughput, because the vertical filling facility means that liquids and solids can be filled into the packs with equal ease, and because the "footprint" of the machine on the factory floor is small.
  • the folding tools serve to form the folds before the sheet material is formed on the former.
  • the infeed area is adapted to receive a roll of sheet material for dispensing the sheet therefrom.
  • the invention may include separate tools for doubling and subsequently further doubling the edge portion of the sheet.
  • the apparatus may include a combined folding tool for doubling and subsequently further doubling the edge portion as aforesaid.

  • the gusset finger assembly 70 is a scissor action device the tip 71 of which moves in the direction of arrow B ( Figure 24) as the sealing elements 42a, 42b move closer together in the direction of arrows A.
  • the sheet material 31 is fed over the forming shoulder 56 without having first been doubled and further doubled in the manner described in relation to Figures 4 to 6. This action results in the sheet material 31 being simply wrapped around the fill tube 43 such that there exists a simple overlap 72 of the longitudinal edges of the sheet material 31.
  • this heater As the overlapping sheet material edges pass the seam heater 68, this heater is operated to form a longitudinally extending seam 23 in the sheet material 31. This action tends to flatten the seam 23 against the fill tube as shown.
  • the forming blade 67 is biassed in use of the apparatus to press the sheet material 31 between the front spreading fingers 66a. Blade 67 contacts the sheet material in such a way as to tend to form a folded pack bottom, similar to the folded bottom of pack 20 ( Figures 2 and 3), extending longitudinally along the sheet material 31 . This is best shown in Figure 25.
  • gusset finger 70 may not be strictly necessary to form the packs of the invention, and in some embodiments would serve primarily to confirm the folds made by the blade 67 and fingers 66a. Moreover the blade/fingers assembly 66a/67 and/or the gusset finger 70 or similar devices may theoretically be incorporated into other embodiments of the apparatus, such as that shown in Figure 14, if desired.
  • the packs are filled between formation of second seam 22a and third seam 22b, and are cropped from the sheet material 31 after forming of the third seam 22b.
  • Any of the methods and apparatuses previously discussed for forming the seams and cropping the packs from the sheet material 31 can be included in the apparatus of Figures 23 to 25. Any other optional features of the invention may also be so included, if necessary after suitable modification.
  • the guillotine or the other cutter mechanism carried by the carriage need not be integral therewith but may be spaced from the elements 42a, 42b.
  • the guillotine or equivalent need not be of a contact type.
  • ultrasound, laser or heat cutters could be employed.
  • the elements 42a, 42b, 62 and 64 need not inco ⁇ orate heaters designed for heat curing of a curable adhesive.
  • the elements 42a, 42b, 62 and 64 may for example press the material 31 into form-locking engagement, or may apply an air-curing adhesive; yet a further possibility is to employ ultrasound welding heads to make the seams.
  • the sealing elements referred to may be suitable for the pressure joining of so called "cold seal" materials. Similar variants on the types of seam-forming members may be employed in the elements 39a, 39b if desired and also in any additional such elements for forming the seam 29.
