Definitions

  • TITLE Foil bag provided with a punched opening and incisions.
  • the invention relates to an improvement of a foil bag which comprises flattened and optionally side folded foil bag portions, provided with a sealed bottom.
  • foil bags usually manufactured from polyethylene(PE) foil, are used in a packaging-machine, which is operated to open and subsequently position the bag into a box, crate or container.
  • a packaging-machine which is operated to open and subsequently position the bag into a box, crate or container.
  • Such a machine is described in Dutch patent nr. 1012033 of the applicant.
  • the openings are punched through two foil layers.
  • a side folded foil bag is used the openings are punched each time through four foil layers.
  • the openings in the foil bag and the diameter of the pin supports are tuned to each other in such a way that during the first step when the upper edge is to be unfolded off the front side of the foil bag it will not simultaneously pull along the rearward side of the foil bag.
  • foil bag open - spread and hold may lead to serious irregularities in the production process.
  • the bag comprises with straight incisions extending from the upper edge of the bag till approximately a 2 mm distance from the upper edge of the opening.
  • This bridged support of approximately 2 mm between the opening and the incision may easily be broken during pulling off of the front side of the foil bag during its opening e.g. by means of a vacuum.
  • the invention is characterized in that the foil bag is provided adjacent to its upper edge with one or more openings having a diameter which is substantially equal or even greater than the external pin diameter of the support and whereas the foil bag is also provided with at least one foil bag portion provided with one or more incisions in the foil bag material at a certain distance from the opening in a circumferential direction, in such a way that during the opening process of the folded foil bag during a first step the front of the flat folded foil bag portion is pulled off the pin support and consequently during a second step the rearward flat foil bag portion is pulled off from the pin support in such a way that the incisions will remove the undesirable mutually adherence of the foil bag portions by introducing additional air between the opposite adhering foil bag portions while being pulled off the pin support so that the foil bag is completely and easily and problemless opened starting from the front flat foil bag portion wereafter the rearward flat foil bag portion is pulled off further from the pin support.
  • a foil bag is used, flattened or side folded, with external dimensions of 60 x 55 cm and an opening diameter of 10 mm whereby two openings are provided at a distance of 20 mm from the upper edge of the foil bag.
  • a foil bag for example a cone bag, only one opening may be provided.
  • an incision must be provided at a minimum distance from the extemal circumference of the opening to secure the suspension of the foil bag upon the pin support in a sufficient way.
  • the rearward flat foil bag portion does not present incisions extending from the upper edge to the opening.
  • the rearward bag portion may not easily be allowed to be pulled off from the support pins so that as a result, the unfolding or opening and subsequently spreading open of the bag is improved and thereof also the positioning of the unfolded en opened bag into a box, crate or container.
  • the forward flattened foil bag is provided with incisions extending from the upper edge to the opening. In this way the bag opening machine will easily pull off the front foil bag portion from the support pins, with little chances on failures.
  • the front side folds are provided with openings and incisions similar to the front flattened foil bag portion and preferably the rearward side folds are provided with openings and incisions similar to the rearward flattened foil portion.
  • the front side folds are provided with openings and incisions similar to the front flattened foil bag portion and preferably the rearward side folds are provided with openings and incisions similar to the rearward flattened foil portion.
  • Fig. 1 is an embodiment of a side folded foil bag having an opening with incisions and with a schematically perspective top view not showing the bottom seal;
  • Fig. 2 shows in a partial front view an opening pattern provided with incisions on or nearby the upper edge in the front side of the foil bag according to
  • Fig.1 shows in a partial front view an opening pattern of a foil bag provided with incisions shaped as perforations;
  • Fig. 4 shows a curved line for an incision at an opening;
  • Fig. 5 shows a foil bag only provided with incisions in the front portion of the foil bag.
  • Fig.1 shows foil bag 1 partially unfolded and opened provided with passing through openings 6, 6.1 , 6.2, 6.3 en 7, 7.1 , 7.2, 7.3 on the front side 2, the rearward side 3 and the side folds 4 and 5.
  • the centre lines 8 and 9 of two pin supports are drawn whereupon a bundle of side folded foil bags is suspended and mounted in the bag opening machine according to the granted patent of the applicant.
  • some incisions 10, 11 are shown so that the intended purpose of additional introduction of air in the foil bag 1 during its opening is achieved.
  • Incisions 10 and 11 are straight lines and extend from the upper edge 12 of the foil bag 1 to the circumferential edge 13 and 14 respectively of an opening 6 or 7 respectively.
  • some additional incisions 15, 16 are provided around openings 6 and 7 to remove the undesirable mutually adherence of the foil bag portions by introducing additional air into the bag while being pulled off the pin support.
  • Fig.3 shows upper edge of a flat foil bag 17 provided with openings 18, 19 and a straight incision 20 and 21 respectively.
  • some perforations 22, 23 are provided around openings 18, 19 which have the purpose to improve the flow of air while pulling off the foil bag from the pin support.
  • the position and the dimensions of the incisions and/or the perforations may be determined by experiment if desired and also depend on and are influenced by the connecting area and the size of a machine vacuum unit, by which a suction force is exerted on the front side of the foil bag to be opened; to which also relates the amount of movement of the machine vacuum unit while pulling away the foil bag.
  • Fig.4 shows a curved incision 24.
  • an incision line 10 11 , 20, 21 may extend e.g. straight from the upper edge of the foil bag to the upper circumferential edge of the opening and then moreover may extend over a length of some millimetres to about 2 centimetres beyond the lower circumferential edge of the opening.
  • Fig.5 shows a special embodiment of the foil bag with reference numbers corresponding to Fig.1 , the rearward foil bag portion or the rear side 3 not being provided with a straight incision, so that the rearward side will pull off less easy from the pin support and as a result the foil bag may be opened and spread open more easily and reliable in the bag opening machine.
  • the forward foil bag portion or the front side 2 as a result is provided with straight incisions 10 and 11 which extend from the upper edge of the foil bag to the openings 6 and 7. Openings 6.2 and 7.2 of the rearward side folds are not provided with incisions similar to the rear side 3 because of production technical reasons.

Abstract

La présente invention concerne une amélioration de sac en film qui comprend des parties de sac en film aplaties et éventuellement à plis latéraux, pourvu d'un fond scellé. Ces sacs en film, habituellement fabriqués à partir de film de polyéthylène (PE), sont utilisés dans une machine emballeuse, qui fonctionne de façon à ouvrir et ensuite à positionner le sac dans une boîte, une manne ou dans un récipient. Ce sac en film comprend, placé à côté de son bord supérieur, une ou plusieurs ouvertures (6) d'un diamètre sensiblement égal ou même supérieur au diamètre de la tige externe du support et ce sac en film comprend aussi une partie pourvue d'une ou de plusieurs incisions (10, 11) pratiquées dans la matière du sac à une certaine distance de l'ouverture dans une direction périphérique, de façon que, pendant le processus d'ouverture du sac en film plié, dans un premier temps l'avant de la partie de sac pliée à plat soit retirée du support à tiges, de sorte que les incisions suppriment l'adhérence mutuelle indésirable des parties du sac en laissant entrer de l'air entre ces parties opposées alors qu'elles sont retirées du support à tiges, ce sac étant alors complètement ouvert facilement et sans problèmes à partir de la partie avant du sac, la partie arrière étant retirées ensuite du support à tige.
