Description

The present invention relates to a pouch of

seed conditioning.

  We know, in the trade, the pockets of seeds that are proposed by garden centers, wholesalers and similar companies, very often in

  stalls, on which are printed indica-

  prices, plant information that can be grown from the seeds, etc. For use, these seed pouches are opened by the user, by tearing a wedge or band extending along an edge, and then the contents are spilled onto the growing substrate. Packaging bags are frequently equipped, for this purpose, with

  corresponding tear lines that facilitate the opening

  the pouch at a specific location. Depression of the empty pouch in the culture substrate, after seeding, to characterize the latter. it

  However, it does not last long because, as a result of

  should be maintained, the covers become quickly illegible or take, at the very least, a

nasty aspect.

  A major disadvantage of these seed pouches

  known is when their content is not inte-

  widely used immediately after opening the pouch.

  Of course, most pouches can be folded

  such that, thanks to a decline in the region of the

  with the discharge orifice, this orifice can again be temporarily closed. Nevertheless, experience has shown that such a re-capitalization of fortune

  the cover does not last long, because of the elasticity

  material of this pouch, so that as a rule, during the handling of a pouch having

  opened, the seeds that are found there

  still wind are sooner or later lost. In addition, such pouches still containing seeds can not be used for seeding tracking, by plugging into the culture substrate to be kept moist. Although the object of the invention is materialized strictly speaking by a large series article intended to

  a single use, it therefore still calls for improvements

in many respects.

  The objective of the invention is to provide a seed packaging pouch, which allows

  to avoid losses of seed remaining in this

chette after opening.

  According to the invention, this objective is achieved thanks to a pouch characterized in that an adhesive layer is deposited on a part of one of its faces, a layer on which, after the opening of the pouch, a region presenting the spill hole of this pouch

  can be folded and recorded permanently in this posi-

  folded, closing the cover again.

  These measures make it possible to re-seal the open pouch, for example after the removal of only a part of its contents, by folding on the pouch and on its adhesive layer the region which is provided with the sampling orifice, then by connecting said region said layer, so that when the sleeve is subsequently manipulated, the rest

  content can not fall or get lost.

  In one embodiment of the invention, the

  The adhesive tape may be in the form of a tape and

  from one edge of the pocket to another. edge of that

  this. The adhesive layer then preferably extends from one edge of the pouch to an opposite edge, transversely or longitudinally on this pouch. Said layer is

  preferably located near a corner of the

  chette, in order to permanently record a folded corner of this

  pouch. In these circumstances, the cover may be new

  calf closed by flap of the region presenting the sampling orifice, along a folding line parallel to

the band of the adhesive layer.

  When, in accordance with the invention, a repetitive permanent-acting adhesive is deposited on the pouch as an adhesive layer, the protection and isolation of

  this adhesive does not require special measures.

  According to the invention, however, to prevent the cover

  to adhere to other objects as well as to confer

  dust-proof, it can be provided on the adhesive layer, a protective strip which is torn off before re-sealing of the pouch. Judiciously, such a band

  tearproof protector will always be provided when the

  adhesive adhesive consists of a double-sided adhesive tape.

common in the trade.

  Because the realization of the packaging pouch according to the invention allows safe storage, in view

  subsequent use of unused seeds

  in the pouch, this pouch itself can not, as so far, be plugged into the culture substrate as an indication of the culture.

  practiced because the seeds remaining in the pouch

  deteriorated by the prevailing moisture.

  According to an improvement of the invention, to nevertheless allow a description of the cultivation practiced, a plug-in tongue, preferably consisting of

  wood and conveniently already provided with corresponding inscriptions.

  dantes, is removably attached to the pouch. Preferably, this fixation is ensured by means of a repetitive permanent-action adhesive deposited on

the little bag.

  The invention will now be described in more detail by way of non-limiting examples, with reference to the accompanying drawings, in which: FIG. 1 is a plan view of a seed pack; Figure 2 is a section along the line II-II of Figure 1 Figure 3 shows the pocket of Figures 1 and 2, after opening and re-sealing; Figure 4 is a section along the line IV-IV of Figure 3;

  FIG. 5 is a plan view of an inbuilt pouch.

  according to a second embodiment; and Figure 6 shows the pocket of Figure 5, after

opening and re-sealing.

  The seed pack 1, containing seeds S and closed on all sides, is conveniently provided,

  in the traditional way, printed information re-

  content, culture advice and possible

  price indications, and it is pierced with a hanging hole 2 for suspension in conventional seed display stands. To facilitate its opening, so as to sow its content, it presents a line

  tear 3 extending parallel to an edge, close to

  mity of it. An adhesive layer 4 in the form of a strip

  is deposited parallel to this line of tearing, sen-

  in the center of the pocket. This layer 4 extends from one edge of the pouch to its opposite edge and it can

  consist of an adhesive with a permanent, repetitive action

  ve, known by itself, or a strip of tape

  double-sided, commercially available. It can be

  covered by a tear-off protective band, not

felt in detail on the drawing.

  A wooden display tab or label 5 is also removably affixed, for example by means of a repetitive permanent-action adhesive, to the surface of the pouch, on the side facing away from the adhesive layer. in the example shown. This tongue

  is judiciously endowed with a spike, as languet-

  plug-in, and bears an inscription designating the se-

contained in the wallet.

  To sow the seeds in the pouch, this pouch is opened by tearing a strip 6 along the tear line 3, then some or all of the contents of the pouch is spread on the

  prepared culture substrate. If, as is often the case,

  the contents of the package are not used.

  read in one go, this pouch can be closed again in the simplest way. It is sufficient for this purpose

  to fold, along a folding edge extending parallel to

  same as the strip adhesive layer, the area of the

  chette which has the sampling port, so that it covers the adhesive layer 4 possibly released

  cover tape and then connect it to this cover.

  che 4 by slight pressure exerted on it. Figures 3 and 4 illustrate the reobbed sleeve of the. so. Thus, even during subsequent manipulations of the pouch, the seeds that remain in this pouch can not fall or be lost. The plug-in tab 5 can then be detached from the pouch and pressed into the

  the culture substrate, in the vicinity of the seeded zone.

  If, subsequently, the remaining contents of the pouch 1 must also be sown, the pouch can be reopened by dissociating the folded region with the adhesive layer

  4. To designate this new seeding, the wallet

  but empty can be pressed into the culture substrate.

  Of course, the shape, the extent and the position of the adhesive layer are not limited to those of the embodiment example from FIGS. 1 to 4, which has just been described. Thus, the adhesive layer could be deposited in points instead of being striped, and also in the longitudinal direction of the pouch instead of the transverse direction thereto. Another advantageous embodiment is shown in FIGS. 5 and 6. In this example, the diaper

  adhesive 4 is disposed in the vicinity of a corner 7 of the

  chette 1 in which a tear line 8 is also formed in advance .. A tear of the wedge 7 along

  the tear line 8 gives rise to a hole allowing

  so much to take seeds from the pouch. To re-cover the cover 1 thus opened, the corner area is

  folded on the adhesive layer 4 around a folding edge

  age 9 possibly materialized by a pre-printing on

  the pouch, after which it is connected to said layer.

  It goes without saying that many modifications can be made to the sleeve described and shown without

depart from the scope of the invention.
