Summary of the invention The present invention provides a stand-up pouch and a method of making the same in a manner to satisfy the aforementioned needs.
Referring to Figure 1 the present invention is a stand-up pouch comprising dry or powdered product, formed from a length of generally flat material, the longitudinal edges of said length being connected together by a longitudinal seal (1), and the opposite ends (2) and (3) of the tube so formed being closed, wherein on one lateral side (5~ only a portion of the plastic container adjacent each of the said ends is folded inwardly so as to form a gusset ~4).
According to the present invention, this pouch will stand on the gusset when presented on the shelf.
I . :
! The present invention also resides in the method for making ~ 25 a stand-up pouch comprising the steps of :
j - supplying a film (10) of a generally flat material, - feeding the film onto a tube (11) so as to make a tube of said film, - sealing the overlapping edges of said film by a long.~tudinal seal bar (12), - forming said gusset by tucking means (13) on one Iateral side only, - sealing said film by sealing means ~14) so as to obtain a pouch which is closed on one of its opposite ends, - filling said pouch by the filling head (11) with the dry or powdered product, - sealing and cutting the filled pouch by cutting (15) and sealing means (14).

Detailed descri~tion of the invention In order to make the invention more readily understood, reference will now be made to the accompanying drawings, in which ;
Fiqure 1 is a perspective view of a pouch as formed on VFFS
(Vertical Form Fill Seal) machine in accordance with the present invention.
Fiqure 2 is a perspective view of another pouch as formed on VFFS-machine in accordance with the present invention.
~ Figure 2 shows the relative position of the gusset which is i located on one side only.
YE~_~ is a perspective view illustrating the pouch turned 9O and standing on the gusset.
20 Figure 4 is a perspective view of the machine used in the ~ method producing a series of plastic pouches according to ;i the present invention.
. .
j3 25 Figures 1 and 2 illustrates a pouch constructed according 9 to the present invention from-a length of generally flat i material, the longitudinal edges of the length having been I sealed together. Said longitudinal seal (1) is located ! either on the front wall or back wall of said pouch and 30 more preferably on the back wallO Consequently, the front wall of the stand-up pouch is free for printed advertising material. On only one of the lateral sidewalls (5), the two sides of the pouch adjacent its opposite ends (2) and (3) have been folded inwardly to form the gusset (4~. The 35 opposite ends of the pouch are closed resp~ctively by a top cross seal (2) and by a bottom cross seal (3).
' ~2~56~
It will be noted that the finished pouch stand on the gusset. The opposite side of the gusset is a straight top.
' Suitable material to be used herein can be a single or a 5 multi-layered generally flat material. Although not ! limited thereto, the preferred construction of the film is a multi-layer lamination of a plastic/paper material or a multi-layer lamination/coextrusion of any plastic material available to the man skilled in the art, i.e. high or low ~ 10 density polyethylene (HDPE or LDPE) or poly~thylene 3 terephtalate (PET) having a thickness of 40 to 200 micrometers. Preferred multi-layered film have a first and ~, second thermoplastic materials, said first material is ', translucent and constitutes the outside layer of the pouch 15 whereas said second material on which the advertising messages are printed constitutes the inside layer. Most ¦ preferred as a outside layer is a low density polyethylene having a thickness of 30 micrometers. Most preferred as a f inside layer is a high density polyethylene having a 20 thickness of 100 micrometers.
This construction of the film is particularly well suited I for a stand up pouch for containing different types of concentrated and unconcentrated dry or powdered products 25 such as, but not limited to automatic dishwasher detergents, laundry detergents, softeners and hard surface cleaners.
In a preferred embodiment of the present invention the 30 straight top located on the opposite side of the gusset is provided with a printed line to indicate to the consumer how to cut the pouch such as to ease and control pouring to the appropriate refillable package.
3~ Turning now to figure 4, the pouch according to the present invention is formed on a conventional Vertical Form Fill Seal (VFFS) machinP. The method for making the pouch of the present invention is a continuous process. A generally flat material (10) for forming the pouches is fed into the VFFS machine. This material preferably comprises weldable or heat-sealable polyethylene. Said material is carried to the forming tube (11) which is also the filling head. The ~'f, free edges of the material are joined together and are , sealed by a longitudinal seal bar (12) so as to form a tube. A tucking device (13) located on only one side as shown in figure 4 allows the formation of the lateral gusset, before said pouch is closed. The tube formed in this way is then sealed by sealing means (14) on one of its opposite ends so as to form a bottom cross seal (3). The pouch formed in this way can now be filled stepwise by the filling head (11). After that, a hori20ntal seal bar (14) makes end seals and the cut-off knife (15) separates the ~¦ fil~ed pouches. After filling and sealing the pouch is turned 90 degrees to stand on the gusset.
