Definitions

  • the invention relates to a bag with flexible walls and a tight closure for the vacuum storage of various products.
  • Document FR-A-2 428 587 already discloses a package for the packaging of products under high vacuum composed of two plastic sheets which are first joined by welding on three sides; the bag thus formed is filled by the side left open and the latter is also sealed. One of the sheets is provided with a valve which is then used to connect the packaging to a vacuum chamber in order to draw the air contained in this packaging. It is therefore necessary to have a source of vacuum when filling the bag, which is precisely what the invention wants to avoid.
  • the subject of the invention is a bag in which a vacuum reserve is established in advance so that the use of this bag does not require the user to have a machine or an apparatus for evacuating when it encloses in the bag of the products to be preserved.
  • a bag with flexible walls and with tight closure for the vacuum storage of various products according to the invention contains an auxiliary pocket limiting a volume which is empty of air before the bag is used; this auxiliary pocket is provided with a means of communicating its volume with that of the bag when the latter has been sealed.
  • auxiliary pocket into the bag and to limit the volume thereof by a wall which is common with at least one wall of the bag, and by an attached sheet and fixed to the face. inside of the bag.
  • the insert sheet is preferably pleated or embossed to give the bag minimum bulk when it is empty of air.
  • the attached sheet may have a central zone of tearable weakening constituting a means of communication between the pocket and the bag.
  • this means may consist of a hole provided in the attached sheet and of a plate closing this hole with a breaking groove in this plate passing in front of the hole; the same means can also be constituted by a pointed central protuberance enabling the perforated sheet to be perforated. This pointed central protuberance can be suspended on one side of the attached sheet in front of an opposing washer pierced with a hole and fixed on the other side of the attached sheet.
  • the auxiliary pocket is a box made of rigid material provided with an easily breakable appendage having an internal channel which opens onto the interior volume of the auxiliary pocket.
  • the auxiliary pocket is advantageously provided with elastic means tending to restore it to its original shape after crushing.
  • the bag of Figure 1 is shown open, in section through a longitudinal plane passing through its middle, the front part drawn in phantom being assumed to be removed to reveal the rear part drawn in solid line.
  • This bag can be made of any suitable material, transparent or opaque, flexible; for example the flexible walls 2, 3 can be produced from two polyethylene sheets which are welded on three sides to leave an upper filling opening 4. It is capable of being sealed in a leaktight manner after filling, in a known manner , either by hot welding, or by means of a transverse strip 5 of adhesive material provided a little below the upper opening 4.
  • the invention is compatible with any type of bag and with any sealing method.
  • the bag 1 contains an auxiliary pocket 6 which limits a volume which has been emptied of its air at the time of manufacture.
  • the auxiliary pocket 6 is obtained using an additional sheet 7 added of flexible material which is welded to the inner face of one of the walls 3 of the bag 1.
  • the welding is carried out along the four edges of the additional sheet 7.
  • the latter is folded or corrugated, thanks to corrugations 8 which prevent the two opposite walls of the auxiliary pocket 6 from adhering to each other when the vacuum has been created in the latter and which allow the pocket to inflate when air enters it.
  • Wrinkling or waving is not always necessary; other means can be used to prevent adhesion of the opposite walls of the auxiliary pocket 6 while allowing it to swell.
  • an area 9 of the additional sheet 7 is smooth; it is used for fixing, for example by gluing, a plate 10, better visible in Figure 2, which constitutes a means of communication, when desired, the interior of the bag 1 with the empty volume d air from the auxiliary pocket 6.
  • the additional sheet 7 is pierced with a hole 11 which is covered and closed by a flat main face 10A of the wafer 10.
  • the wafer 10 On its opposite main face 10B the wafer 10 has a transverse groove 12 which constitutes a starting point and which passes in front of the hole 11. This groove 12 could be on the main face 1 OA just in front of the hole 11 if it did not extend to the two opposite edges of the wafer 10.
  • the pocket 6 is emptied of its air. After filling the bag 1 in products to be stored under vacuum, it is sealed in the usual manner provided, then, through the walls 2, 3 one grasps the plate 10 and breaks it along the groove 12. The hole 11 then allows the air contained in the bag 1 to enter the auxiliary pocket 6 which inflates.
  • the air pressure in the assembly consisting of the bag 1 and the auxiliary pocket 6 is reduced by the same amount and it becomes significantly lower than atmospheric pressure, according to the ratio between the volume of the bag 1, its degree of filling, the volume of the auxiliary bag 6 and the degree of vacuum produced in it at the time of manufacture.
  • the plate 10 is fixed to the outside face of the additional sheet 7 relative to the pocket 6. It could be fixed over the hole 11 on the inside face of this sheet 7, that is to say ie inside the pocket 6. It would then serve to prevent the adhesion of the two opposite sheets 7 and 3 of this pocket.
  • FIG 4 shows an alternative embodiment of the communication means.
  • the additional sheet 7 is not pierced.
  • an opposing washer 13 pierced with a central hole 14.
  • a second washer 15 having a central hole 16 and a pointed central protuberance 17 held suspended by means of a flexible sheet 18. The latter is welded at its periphery to the additional sheet 7 and it is pierced with a hole 19 just opposite the hole 16.
  • the pointed central protuberance 17 is located opposite the hole 14 of the first opposing washer 13.
  • the auxiliary pocket 6 is incorporated into the bag 1, inside of it, at the very time of its manufacture. It will be noted that the auxiliary pocket 6 could be made outside the bag 1 by fitting and fixing the additional sheet 7 outside the wall 3. In this case, it is this which would be provided a means of communication.
  • FIG. 3 shows an auxiliary pocket 6 made of rigid molded material, having two opposite main walls 20A, 20B held spaced apart by internal partitions 21 pierced with communication holes 22 which could be replaced by total interruptions of the partitions 21, for example at one end of it.
  • the auxiliary pocket is analogous to a box; it is independent of the bag into which it is introduced when the latter is used; preferably it has an outer face covered with a layer of adhesive material 23 which makes it possible, if it is deemed desirable, to fix it to an inner face of a bag 1.
  • the auxiliary pocket 6 of FIG. 3 is provided with an appendage 24 in which is formed an interior channel 25 which communicates with the interior volume of the pocket 6 but which is closed relative to the exterior.
  • Appendix 24 is easily breakable; it can have predetermined breaking lines, if desired. It is easily broken through the walls 2, 3 of the bag 1 when the latter has been filled and sealed.
  • the channel 25 of the appendix 24 is preferably filled with a porous material allowing the air to circulate slowly between the bag 1 and the auxiliary pocket 6.
  • the appendix 24 could be provided with a base 26 similar to a washer cut out from the wall of the box, as indicated in phantom. This washer could be attached to the additional sheet 7, the hole 11 thereof in Figure 2 being in the extension of the channel 25. There would thus be, with an auxiliary pocket 6 incorporated in the bag 1, another means of setting communication between the bag and the auxiliary pocket.
  • FIG. 5 shows a bag 1 in which the auxiliary pocket 6 is produced using a transverse partition (attached sheet 27) which has a raised edge 28 by which it is welded to the inner face of the bag 1, after making of the last.
  • This partition 27 has a central zone 29 of predetermined weakening which makes it possible to crack it when one pulls on either side of this zone 29, through the walls of the bag 1 previously filled and sealed.
  • the vacuum in the auxiliary pocket 6 of the invention is obtained by any available means.
  • Air can be drawn in using an air pump.
  • the auxiliary pocket 6 has rigid walls as in the example in FIG. 3, it retains its shape. After filling the bag 1 with products to be preserved, as soon as this auxiliary bag 6 is placed in communication with the bag 1, the residual air spreads itself in this bag 6.
  • FIG. 5 relates to an example of an auxiliary bag and pocket where the walls are of semi-rigid and elastic material tending to retain or resume their initial shape after the air has been drawn in.
  • auxiliary pocket 6 when the auxiliary pocket 6 is provided with elastic means, a vacuum can be created there without using an air pump. Just flatten this pocket before closing it tightly. When it then returns to its original shape, it is empty of air.
  • the auxiliary pocket 6 can be given suitable elasticity by making it with semi-rigid and elastic walls capable of resuming their initial shape after crushing. If the walls are not capable of resuming their initial shape alone, an internal spring can be provided which tends to spread these walls apart; in Figure 1 there is drawn in phantom an inner spring 30 of spacing. This spring 30 is held in its place by guide means, not shown.
  • the elastic means are incorporated into the walls of the auxiliary pocket 6 or attached to this pocket as elastic spacer elements.
  • the volume filled with air from the auxiliary pocket 6 need not be of considerable importance. If the bag 1 to be filled has a volume V, after filling, it contains only a residual volume of air v which may be very small. If the pocket auxiliary 6 filled with air has a volume equal to 10 v, when it has been emptied of its air to a practically zero pressure and then it is placed in communication with the residual air volume v, the pressure in the bag 1 becomes one tenth of the atmospheric pressure. The largest fraction of the residual air is then found in the auxiliary pocket 6. The communication means in all cases has only a very small passage section, in particular when an appendage 24 with an internal channel is used. 25 filled with porous material. As a result, the largest fraction of the residual air is trapped in the auxiliary pocket and isolated from the products contained in the bag. The latter can therefore be used by anyone in any place without a vacuum machine.
