Definitions

• This invention is concerned with improvements in and relating to resealable flexible dispenser/containers, especially for sheet-like materials.
• Such containers generally comprise a pouch formed of flexible plastics material having, in one face thereof, an aperture for dispensing sheets contained in the pouch, and a resealable closure overlying the aperture, resealing generally being effected by means of a releasable adhesive.
• the invention provides a flexible dispenser/container comprising a flexible pouch formed of flexible plastics sheet material and having an aperture in one face of the pouch for dispensing objects therefrom; a flap of flexible material secured at one
• SUBSTITUTESHEET end to the said face of the pouch for releasably sealing the aperture in that face by means of the action of a releasable adhesive between the flap and the outer surface of the pouch; a further sheet of flexible plastics material being attached to the undersurface of the said face to underlie the whole of the area of the aperture in that face, the further sheet being provided with an aperture corresponding to the aperture in the major face of the pouch but of such dimensions that an inner rim of the said further sheet material extends inwardly of the margins of the aperture in the said face.
• the inner rim of flexible material provided by the further sheet attached to the underside of the face of the pouch serves to minimise possible contamination, by liquid present on the contents to be dispensed from the container.of that part of the outer surface of the pouch which serves to bond with the closure flap by means of the releasable adhesive, by liquid present on the material to be dispensed from the container.
• the aperture in the said further sheet may simply be cut out and the material therefrom discarded.
• the aperture in the further sheet is formed as a flap which is, in turn, bonded to the flap serving to close the aperture in the pouch. This arrangement serves two purposes. Firstly, the sealing flap is

• Figure 2 is a cross-section on the line I-I, through the container shown in Figure 1;
• Figure 3 is a perspective view of a modified embodiment of container in accordance with the invention.
• a container in accordance with the invention comprises a pouch 1 formed of flexible plastics material which may be of monolayer or multilayer construction.
• An aperture 2 is formed in upper face of the pouch for dispensing the contents of the pouch.
• a sealing flap 3, which commonly takes the form of a label bearing information as to the contents of the container, is bonded at one end to the surface of the pouch and is provided on its undersurface with a
• SUBSTITUTESHEET layer of releasable adhesive 4 partially masked by masking layer 5 bonded to the adhesive 4.
• the adhesive 4 will be a pressure sensitive release adhesive.
• a further layer 6 (see Figures 1 and 2) is attached to the undersurface of the upper face of pouch 1 by being bonded thereto and has an aperture formed therein but of smaller dimensions than aperture 2 in the upper face of the pouch, whereby a rim 7 of the further sheet extends around the inside margin of aperture 2.
• the further sheet 6 is also formed of flexible plastics material, and may, as shown in Figure 2, at 6' , overlay the edges of a stack of sheets in the pouch.
• the container is sealed by closing flap 3 over aperture 2 whereby it is temporarily bonded by means of adhesive 4. Similarly the container is opened by releasing flap 3.
• container shown in Figure 3 of the drawings also comprises a pouch 1 having an aperture 2 sealed by flap 3 provided with an underlayer of adhesive 4.
• flap 3 provided with an underlayer of adhesive 4.
• SUBSTITUTESHEET is attached to the underside of the surface of pouch 1 and is provided with an aperture corresponding with but of somewhat lesser dimensions than aperture 2, whereby to provide a rim 7 around the inner margins of aperture
• the further sheet 6 is attached to the pouch 1 by extending to and being incorporated in, the transverse end seals defining the end of pouch 1. Further, in the case of the embodiment of Figure 3, that portion of the further sheet 6 which has been cut out to form the aperture in that sheet is not fully severed from the sheet but takes the form of a flap 8 which is adhered to the underside of closure flap
