Definitions

  • the invention relates to a package comprising at least two opposite walls which are bonded together along a longitudinally extending bonding seam, each wall comprising at least two bonded-together wall members, which are folded onto each other about a fold line.
  • the invention also relates to a method for manufacturing such a package.
  • Such a package which is known from US patent US-A-2,189,174, is opened by taking hold of a first pair of two bonded-together wall members being folded onto each other about a fold line with one hand and taking hold of a second pair of two bonded-together wall members being folded onto each other about a fold line with the other hand. Subsequently, said pairs or wall members are moved apart, thus breaking the bonding seam between the opposite walls and forming an opening between the walls. As long as said moving apart of said pairs of wall members is continued, the opening will increase in size until the bonding seam between the walls is fully broken.
  • the opening is comparatively limited in size, so as to avoid the risk of liquid easily flowing out of the package.
  • the opening is large enough to allow easy pouring of the liquid readily from the package, drinking the liquid from the package or gaining access to the liquid by means of a straw, for example, for sucking the liquid from the package by means of said straw.
  • the object of the invention is to provide a package in which opening of the package is much easier, with an opening of a predetermined size being obtained.
  • an opening bounded by the comparatively small wall members is obtained. Said opening gives access to a product present inside the package.
  • the size of the opening is determined and also maximised by the dimensions of the wall members. Undesirable opening of the package further than is necessary for gaining access to the space inside the package by exerting forces in directions extending parallel to the longitudinal direction of the bonded bonding seam is not possible, therefore. This is advantageous in particular when the package is used for a consumable liquid, such as a soft drink or an alcoholic beverage. Once the package has been opened, a person can pour the liquid directly into his/her mouth by raising the package to his/her lips or insert a straw into the opening. The comparatively limited size of the opening practically rules out the risk of spilling the consumable liquid.
  • the volume of the space present inside the package is increased. Since the volume is increased, there is no risk of the product present inside the package, such as a fluid or another material, undesirably spilling from the package.
  • a user only needs to take hold of the parts connected by the bonding seam of the walls positioned on either side of the wall members in order to open the package. As a result, no pressure is exerted on the package by the user himself, so that the contents of the package are prevented from undesirably spilling from the package.
  • a drawback of the known package is the fact that a pressure is exerted on the package upon depressing the corner portion. As a result of said pressure being exerted on the package, the liquid contained in the package may squirt from the package. This is undesirable, of course.
  • the package according to the invention does not comprise a scored portion that might lead to the package being undesirably opened upon exertion of a force thereon.
  • the package according to the invention may be tetrahedron-shaped, but it may also have any other shape, providing the package comprises at least two opposite walls connected by a bonding seam.
  • One embodiment of the package according to the invention is characterized in that the wall members of one wall are positioned on a side of said one wall remote from the other wall, and vice versa.
  • the wall members extend parallel to the walls, so that an attractive appearance is obtained, without any projecting parts being present on the package.
  • the wall member abutting against a wall is bonded thereto, so that the wall members will continue to abut against the wall.
  • Yet another embodiment of the package according to the invention is characterized in that the wall members of one wall extend in a direction opposed to the direction in which the wall members of the other wall extend.
  • the wall members extend in opposite directions, the number of superposed wall members and walls present at the location of the wall members is comparatively limited, so that differences in thickness in the package are prevented, whilst the bonding together of the walls and the wall members can take place in a relatively simple manner.
  • Yet another embodiment of the package according to the invention is characterized in that the bonded-together wall members of a wall extend in a direction transversely to the longitudinal direction of the bonding seam over at least substantially the entire package.
  • the walls of the package are folded double in a direction away from the bonding seam, said folded-together walls being sealed by means of a further bonding seam.
  • This object is accomplished by the method according to the invention in that longitudinal sides of a strip-shaped foil are bonded together, at least two pairs of wall members are folded onto each other about fold lines extending parallel to the longitudinal side, the wall members of each pair are bonded together, the pairs of wall members are positioned opposite each other, and the walls positioned on either side of the wall members are bonded together by means of a bonding seam extending transversely to said longitudinal sides.
  • the package according to the invention can thus be manufactured fully automatically, using means that are known per se, quickly and without additional parts being required.
  • Fig. 1 is a perspective view of a package 1 according to the invention, which is tetrahedron-shaped.
  • the package 1 comprises triangular walls 2, 3, 4, 5.
  • the walls are made of polyethylene, for example.
  • the package 1 comprises two pairs of wall members 6,7 and 8, 9, respectively, which are folded onto each other about a fold line 10, 11.
  • the wall member 7, 9 is further folded, via a fold line 12, 13, onto a wall member 14, 15 that faces away from the wall member 6, 8.
  • the walls 3, 5 abut against each other via edges 18, 19 extending over the segment 16, 17 and are bonded together by means of a heat sealing process, forming a bonding seam (not shown) extending parallel to said edges.
  • the two pairs of wall members 6, 7 and 8, 9, respectively, are positioned opposite each other, with the wall members 6, 7 and 8, 9, respectively, extending in opposite directions.
  • the walls 2, 4 are connected via edges 22, 23 extending over a segment 20, 21 by means of a bonding seam formed by heat sealing. Since the edges 18, 19 and 22, 23, respectively, are evenly offset with respect to each other, the edges 18, 19 and 22, 23 extend transversely to each other, and a triangular shape of the walls 2, 3, 4, 5 is automatically obtained. Both the folded-together wall members 6, 7 and the folded-together wall members 8, 9 are present in the edge 23.
  • the package 1 is made of a strip-shaped foil, wherein longitudinal sides 24, 25 are positioned in overlapping relationship for bonding the edges 18, 19 and 22, 23, respectively, and bonded together by means of a heat sealing process.
  • a material to be packaged is introduced in the space bounded by the package 1.
  • Said material may be a liquid, for example, such as an alcoholic beverage.
  • a user who wishes to open the package 1 in order to use or consume its contents will take hold of the parts 26, 27 of the edges 18, 19 positioned on either side of the wall members 6-9 and move said parts 26, 27 in directions away from each other as indicated by the arrows P1, P2.
  • the directions indicated by the arrows P1, P2 extend parallel to the longitudinal direction of the edges 18, 19 and the bonding seam formed thereon by heat sealing. While the parts 26, 27 are being moved in the directions indicated by the arrows P1, P2, the forces being exerted on the wall members 6, 7, 8, 9, cause the wall members 6, 7, 8, 9 to pivot about the fold lines 12, 13 in the directions indicated by the arrows P3, P4, from the position that is shown in Fig. 4 to the position that is shown in Fig. 5.
  • the wall members 6, 7, 8, 9 When the parts 26, 27 are subsequently moved in the directions indicated by the arrows P1, P2, the wall members 6, 7, 8, 9 will take up the positions as shown in Fig. 6, in which an opening 28 is formed between the wall members 6, 7, 8, 9, which opening extends into the space bounded by the package (see also Fig. 2). Further movement of the parts 26, 27 in the directions indicated by the arrows P1, P2 will result in the walls 6, 9 and 7, 8, respectively, moving into abutment with each other, causing the opening 28 to be closed again. A small opening 28 will remain at all times, however, from which liquid that is present in the package 1 may spill. The size of the opening 28 is determined and also maximised by the dimensions of the walls 6, 7, 8, 9.
  • the package can be manufactured in a continuous process in a simple manner. It is also possible, of course, to form the package of individually interconnected wall members.
  • a polyethylene foil may be used as the material for the package 1. It is also possible, however, to use other strip-shaped foils from a laminate, for example, such as metallized polyester, polypropylene/polyethylene or polyester/polyethylene.
