Abstract
A photographic laboratory work pouch comprises a front wall 2 of rigid material such as paper and a rear wall of transparent material, the wall 2 having a tear off strip 9 and a fold over flap 8 for closing the pouch opening. The flap is secured by adhesive on a patch 14 acting through an opening in the flap 8 to contact the transparent wall, the patch having an adhesive- repellent rear surface. The transparent wall terminates below the adhesive region. <IMAGE>
Description
SPECIFICATION
Photographic laboratory work pouch
The invention relates to a pouch for photographic laboratory work of the kind comprising a front wall and a rear wall, of which one is made of a material having sufficient rigidity, preferably paper, and the other is made of a transparent material, preferably a thinner plastics foil, and the paper wall provided with a tear-off strip along its outer margin, and further comprising an opening and a part projecting beyond this opening and adapted to be folded over to close the pouch, said part being provided on that side thereof which faces the other wall with an adhesive region to which a resealabe adhesive has been applied whilst presenting an adhesiverepellent area in the corresponding position on its opposite side.
A pouch of the kind specified is known from
German Gebrauchsmuster specification 78 34 984. In this pouch a recess is provided in the transparent wall within the region of the fold-over part and a carrier applied from the outside in such a way that the transparent wall is provided with an adhesive on the inside thereof within the region of said recess. The paper wall is also provided with a recess on oppositely situated part so that the paper wall will not come into contact with the adhesive prior to closing of the pouch. Since the two recesses must precisely coincide with one another they are formed only after the joining of the two walls in a separate work stage, only after which the carrier can be applied.For first-time closing, or sealing of the pouch that strip of the paper wall which is opposite the fold-over part of the transparent wall and which is a tear-off strip'is torn off whereupon the pouch is sealed. The adhesive here co-acts with the paper surface which may cause problems of ripping when the pouch is opened and therefore make re-sealing of the pouch difficuit.
It is the object of the invention to provide a photographic laboratory work pouch of the kind specified which is easier to make and to use.
According to the invention there is provided a photographic laboratory work pouch comprising a front wall and a rear wall, one of which is made from a material having sufficient rigidity, and the other from a transparent material, and in which a tear-off strip is provided on the paper wall along the outer margin thereof, and comprising an opening and a part which projects above said opening and is adapted to be folded over for closing the pouch, said part being provided on that side thereof which faces the other wall with an adhesive region to which a re-usable adhesive has been applied and in the corresponding region on the other side thereof with an adhesive repellent area, and wherein the wall which comprises the fold-over part consists of the material which has the required degree of rigidity and the wall which is made of the transparent material terminates below the adhesive region.
Advantageously an adhesive strip which is preferably adapted to be activated by pressure and/or heat, is arranged beneath the opening edge. This enables the pouch to be finally sealed when desired, notably when the photographic laboratory work has been completed.
The invention is hereinafter more particularly described in one embodiment thereof illustrated by way of example in the accompanying drawings in which:
Figure 1 is a perspective view of the pouch as viewed from the front side,
Figure 2 shows the pouch according to Figure 1 with the severed tear-off strip and in closed, i.e.
sealed condition, and
Figure 3 is a rear-view of the unsealed pouch shown in Figure 1.
The pouch 1 comprises a front wall 2 made of a paper having sufficient rigidity or durability, for example being of a 100 to 1 50 g- quality, and a rear wall 3 made of a thin transparent plastics foil such as a polyethylene foil or also a pergamine foil.
These two walls are welded or glued together along their two lateral edges 4, 5 and along the bottom edge 6. With this end in view the front paper wall may be a polyethylene coated material.
The front wall 2 is adapted to be provided with the usual data for pouches containing photographic laboratory work. The front wall 2 comprises a strip 8 which is adjacent the opening 7 and projects beyond the latter so as to be adapted to be folded over the edge of the opening and over the rear wall 3. Next to this strip 8 is a tear-off strip 9 which is connected to strip 8 by a perforation line 1 0.
The front wall 2 is provided, in the region of strip 8 which projects above the opening 7, with a recess or hole 11 shown to be of circular form in the illustrated example, but which may also have any other desired configuration. On the external side of the front wall, remote from the rear wall 3, there is provided a carrier 12 which overlaps the hole 11 and which is provided with an adhesive 13 applied to that side thereof which faces the hole 11, the adhesive adhering firmly to the paper of the front wall 2 but being detachable from the material which is used for the rear wall 3. The adhesive 13 is further adapted to be readily detached when required from a coating, in particular a silicon coating, applied to the rear side 14 of the carrier 12.To this end the rear side 14 of the carrier 12 is silicon-coated so as to prevent adhesive sticking together of a plurality of superposed or stacked pouches.
In the above described embodiment the rear wall 3 of the pouch which in the sealed or closed condition of the pouch 1 co-acts with the adhesive 13 is made of a plastics foil or of pergamine foil.
However, a different material may also be chosen for this wall, the vital factor being that that side of the rear wall 3 which is designed to co-act with the adhesive 13 should be so constituted that no fibres will be ripped or torn out from its surface when the adhesive 1 3 is detached or lifted off the surface of wall 3, in order to enable ready re sealing of the pouch.
A trace 1 5 of a heat-and/or pressure-activated adhesive extends transversely across the whole opening of the pouch a small distance away from said opening 7.
In use, when a film is accepted, the tear-off strip 9 is detached and given to the customer. The film is placed inside the pouch 1 and then the pouch is re-openably sealed by turning strip 8 over the opening 7 and pressing the adhesive 1 3 against the outside of the rear wall 3. At the photographic laboratory the pouch is opened and the film removed. When all photographic work has been duly completed the strip 8 can be re-sealed by means of the adhesive 1 3. Moreover, by activation of the adhesive trace 15 by means of pressure and/or heat, the pouch opening is more permanently sealed off so that its contents will not escape during return transport to the final customer.
When empty, as yet unused pouches are stacked on top of one another the side which is provided with the adhesive 13 lies always on top of the silicon-coated rear side 14 of the carrier 12 of an adjacent pouch. This prevents the pouches from sticking together. Preferably the carrier 12 is somewhat larger than the hole or recess 11 in order to prevent sticking-together of the pouches even when these are not quite perfectly lined up in a stack.
Claims (3)
1. A photographic laboratory work pouch comprising a front wall and a rear wall, one of which is made from a material having sufficient rigidity, and the other from a transparent material, and in which a tear-off strip is provided on the paper wall along the outer margin thereof, and comprising an opening and a part which projects above said opening and is adapted to be folded over for closing the pouch, said part being provided on that side thereof which faces the other wall with an adhesive region to which a reusable adhesive has been applied and in the corresponding region on the other side thereof with an adhesive repellent area, and wherein the wall which comprises the fold-over part consists of the material which has the required degree of rigidity and the wall which is made of the transparent material terminates below the adhesive region.
2. A photographic laboratory work pouch according to claim 1 , including an adhesive strip which is adapted to be activated by pressure and/or heat beneath the edge of the pouch opening.
