Definitions

• This invention relates to a packet, in particular, a packet used for packaging a food, confectionery, pharmaceutical or other type of product.
• the packet according to the invention is preferable for a product in stick, bar, or powder form, in pieces or in any other like form.
• Packets for chewing gum sticks which comprise a cardboard box for containing the sticks.
• the sticks are normally placed side by side in such a way that a single stick can be removed from a row while leaving the others inside the packet.
• the sticks are normally individually wrapped in a primary wrapping.
• This invention therefore provides a packet for products, where the products are wrapped in a respective wrapping, characterized in that it comprises means for retaining the products inside the packet and capable of exerting a predetermined force.
• These means can be embodied by permanent adhesion means for attaching at least one wrapping to at least one part of the packet.
• These adhesion means are located on parts that can be separated in a predetermined manner from the wrapping or from the packet. The packet thus obtained guarantees a predetermined force for detaching the product from the packet but without significantly increasing the complexity and cost of production.
• Figure 1 illustrates the product wrapped according to a first wrapping style.
• Figure 2 illustrates the product wrapped according to a second wrapping style.
• Figure 3 illustrates the product wrapped according to a third wrapping style.
• Figure 4 illustrates a group of products inside a first form of receptacle.
• Figure 5 illustrates a group of products inside a second form of receptacle.
• Figure 6 illustrates a group of products inside a first form of multiple receptacle.
• Figure 7 illustrates a first embodiment of the separable parts of the receptacle.
• Figure 8 illustrates a second embodiment of the separable parts of the receptacle.
• Figure 9 illustrates a third embodiment of the separable parts of the receptacle.

• Figure 13 illustrates a second embodiment of the separable parts of the sheet.
• Figure 14 illustrates a third embodiment of the separable parts of the sheet.
• Figure 15 is a cross section of a first embodiment of the packet composed of the wrapped product, one sheet and one outer receptacle.
• Figure 16 is a cross section of a second embodiment of the packet composed of two superposed groups of wrapped products, two sheets and one outer receptacle.
• Figure 17 illustrates a first embodiment of the separable parts of the wrapping;
• Figure 18 illustrates a detail of the preceding embodiment where one product has been taken out of the packet.
• Figure 19 illustrates a second embodiment of the separable parts of the wrapping.
• Figure 20 illustrates a third embodiment of the separable parts of the wrapping.
• Figure 21 is a cross section of an embodiment of the packet composed of a series of superposed groups of wrapped products, one sheet and one outer receptacle.
• Figures 1 and 2 show two different product wrapping styles (10, 10a) where the wrapping (11) is made from a sheet folded round the product.
• Other examples of wrapping styles of this type are not illustrated because they are well known to experts in the trade and irrelevant to the invention.
• Figure 3 shows a third product wrapping style (10 b), where the wrapping (11) is made from a sheet that is folded and sealed round the product.
• wrapping styles of this type are not illustrated because they are well known to experts in the trade and irrelevant to the invention.
• the wrappings may be made of paper, paraffin paper, metallic foil, plastic foil or any combination of these materials.
• Figures 4 and 5 are two examples of receptacles (41) which may constitute the outer part of the packet.
• the outer receptacle is designed to contain the product at least partially and, in a first preferred embodiment of it, comprises a rear side to which are applied the permanent adhesion means (80) which hold the product (10) in position.
• the outer receptacle comprises 5 sides all around the products and an open side (42) that enables the products to be dispensed.
• the packet has a lid (43) that closes the open side.
• the form and closing action of the lid may be embodied in many different ways which are not illustrated since they are irrelevant to the operation of the invention.
• Figure 6 shows a third preferred embodiment (60) of the packet, comprising two or more receptacles (41) joined to each other.
• the receptacles may be made of card, paper, plastic, foil or any combination of these or equivalent materials.
• Figure 7 shows a packet where the permanent adhesion means (80) are provided on a separable part (81) of the receptacle (41).
• the separable part (81) of the receptacle is attached to the receptacle by separating lines (82) made on the receptacle (41) itself.
• the separating lines (82) are at least partly in the form of perforated lines made in the material the receptacle (41) is made of.
• the separable parts of the receptacle are in the form of tabs (81) that protrude from one of the edges of one face of the receptacle.
• the tabs may have any shape and, in particular, they are substantially circular in shape.
• the tabs (81a) protrude lengthways past the end of the product allowing the product to be dispensed without being touched.
• the separable parts (81b) of the receptacle are provided on the inside face of one of the sides of the receptacle.
• Yet another preferred embodiment of the packet comprises a sheet placed inside the receptacle.
• the sheet (110) is designed to support the products (10) and, in a first preferred embodiment of it, comprises a rear face to which are applied the permanent adhesion means (80) which hold the product (10) in position.
• the sheet is shaped like a pocket surrounding the product on 5 sides.
• the sheet is shaped like a pocket surrounding the product on 4 sides.
• the sheet may be placed round 2 or 3 sides of the wrapped product.
• the sheet surrounds the wrapped product completely.
• the sheets (110) may be made of paper, paraffin paper, metallic foil, plastic foil or any combination of these materials.
• Figure 12 shows a packet where the permanent adhesion means (80) are provided on a separable part (130) of the sheet (110) located along one edge of the sheet.
• the separable part of the sheet extends on several adjacent sides of the sheet, that is, in this specific case, the top, one lateral face and the bottom.
• the separable part (130) of the sheet is attached to the sheet by separating lines (131) made on the sheet.
• Other solutions are also possible however, such as, for example, the separation of part of the sheet to a desired "depth", equivalent to detaching a part of the foil layer of a multilayer material.
• the separating lines (131) are at least partly in the form of perforated lines made in the material the sheet (110) is made of. hi another embodiment, the separating lines might be in the form of non- perforating score lines impressed in the material the sheet (110) is made of.
• the separating lines are designed in such a way as to require a predetermined tearing force. By changing their length, depth and direction, it is possible to predetermine the force necessary to tear them in order to dispense the product.
• permanent adhesion means 140 are provided between the sheet (110) and the outer receptacle (41). These means keep the sheet securely inside the receptacle while the wrapped product is being dispensed.
• the permanent adhesion means are in the form of a permanent two-sided adhesive foil support where the central, separable support constitutes the sheet (110), the adhesive side facing the packet constituting the permanent adhesion means (140) and the adhesive side facing the product wrapping constituting the permanent adhesion means (80).
• the packet shown in cross section in Figure 16, where there are two superposed groups of wrapped products enclosed within respective sheets, permanent adhesion means (170) are provided between the sheets (110) located inside the receptacle (41).
• the permanent adhesion means are provided on a separable part (170) of the wrapping (11).
• the separable part (170) of the wrapping is attached to the wrapping by separating lines (171) made on the wrapping itself.
• the separating lines (171) may be in the form of perforated lines made in the material the wrapping (11) is made of. These separating lines might also be in the form of non-perforated score lines impressed in the material the wrapping (11) is made of.
• the separating lines are designed in such a way as to require a predetermined tearing force. By changing their length, depth and direction, it is possible to predetermine the force necessary to tear them in order to dispense the product.
• the separating lines are positioned in such a way that the wrapping (11) remains whole even after being torn since the separating line (171) is located beyond of the sealing line.
• the separating line (171) is positioned on the wrapping in such a way that the action of dispensing a wrapped product uncovers a part (9) of the product large enough to enable the bare product to be pulled out of the rest of the wrapping (l ib) directly with one's mouth and without touching it with one's fingers.
• the distance between the separating line and the edge of the product that will be uncovered must be greater than 3 millimetres, that is to say, the part (9) of the product that is uncovered when the product is dispensed from the packet must be at least 3 mm long.
• the distance between the separating line and the edge of the product that will be uncovered must not exceed half the length of the product itself; that is to say, the part (9) of the product that is uncovered when the product is dispensed from the packet must be less than half the length of the product itself.
• the packet contains a group of superposed products.
• permanent adhesion means (80) are provided between the last wrapping (11) and the sheet (110) and non-permanent adhesion means (210) are provided between the wrappings (11) of the single products.
• These adhesion means may be provided on at least one of the two main faces, that is to say, one of the two large faces, of the wrapped product, on a lateral face or on an end face of the wrapped product.
• the products in the packet may be placed side by side in two or more superposed groups, as shown for example in Figure 16, or the products themselves may be superposed and two more groups of superposed products placed side by side, as shown in Figure 5.
• the permanent adhesion means may be embodied by permanent adhesives or other permanent mechanical fixing systems.
• adhesives hot-melt glue, cold glue and contact glue may be used.
• the adhesion means are considered permanent when the force necessary to detach them exceeds the force needed to tear a part of the surface they adhere to.
• the non-permanent adhesion means may be embodied by wax or detachable adhesives.
• the packaging principles of this invention can be applied to a multiplicity of products which may be edible products such as chewing gums, bars of chocolate, biscuits or snacks.
• the products that can be packaged according to the invention may also be in granular or powder form or they may be loose or all arranged in the same direction. These include sugar, tea, tobacco and coffee products.
• They may be pharmaceuticals, parapharmaceuticals or nutritionals. These include, aspirins, condoms and vitamins.
• the packets according to the invention can be made by permanently attaching the wrapped product to a sheet, inserting the sheet into an outer receptacle and then completing the formation of the receptacle in such a way that the consumer can grip and dispense a product by tearing the separable part, which may be either part of the sheet or part of the wrapping.
• a sheet is inserted into the outer receptacle, the wrapped product permanently attached to the sheet, and the formation of the receptacle completed in such a way that the consumer can grip and dispense a product by tearing the separable part, which may be either part of the sheet or part of the wrapping.
• the packets according to the invention can be made by permanently attaching the wrapped product to an outer receptacle completing the formation of the receptacle in such a way that the consumer can grip and dispense a product by tearing the separable part, which may be either part of the receptacle or part of the wrapping.
• a weakened or separating line is made in a wrapping material, the product wrapped in the material and a part of the wrapping material then permanently attached inside a packet.
• the invention thus provides a packet in which the product can be easily packaged and adequately retained until the moment of use even after the products adjacent to it have been dispensed, thanks to the fact that the retaining force is exerted by a part of the packet or product wrapping that is torn by the user when required. This force is therefore predetermined.
