Definitions

  • This invention relates to packaging in accordance with the precharacterising portion of claim 1.
  • Packaging of this type is very widely used especially for the packaging of premoistened or preimpregnated products such as e.g. the small tissues or towels commonly known as “wet wipes”.
  • packaging essentially comprising rigid containers comprising a containment body (which may be cylindrical) with an associated lid provided with a selectively recloseable opening for removal/dispensing of the products has proved itself for this particular application over the years.
  • the products in question take the form of a sheet provided with pre-cut lines of weakness at predetermined distances.
  • the sheet When the sheet is removed from the delivery opening, it is subdivided along the pre-cut lines as a result of a joint effect with springy structures which project towards the interior of the opening. All this is to bring about the removal of individual wipes as a result of the effect of the above mentioned subdivision.
  • the arrangement which provides for the use of a rigid container, also substantially comprising a tray provided with a selectively openable lid, has also proved itself. Opening the lid makes it possible to gain access to a pack of individual wipes or towels which are folded in a generally concatenated arrangement so as to form a chain of "interleaved" products. In this way the removal of an individual product from the packaging places the subsequent product in a position ready to be taken out.
  • the envelope or bag container (of the "flowpack" type) is no longer used to contain the refill for the rigid container, but directly constitutes the container from which the products, which are preferably arranged in the concatenated sequence described above, can be progressively removed through an opening provided in the container wall.
  • This opening is initially closed by a protective flap, also of flexible material, initially designed to seal off, when the pack is complete, the opening through which the products are taken out with a view for dispatch for distribution and sale.
  • the aforesaid flap is attached adhesively to the body of the packaging along the perimeter of the opening which the flap is intended to close off.
  • the opening in the wall of the packaging is still not yet present, but only defined around its perimeter by a line pre-cut for separation (e.g. punching or perforation).
  • the closure flap is then initially attached adhesively to the wall of the packaging over its entire surface, and therefore also in the region which is intended to lie within the pre-cut line defining the perimeter of the opening.
  • the flap When the consumer first lifts the flap of the packaging, the flap tends to pull together with it the surface of the wall to which it is adhesively bonded. While the portion of this surface which is outside the pre-cut line remains attached to the remainder of the wall of the packaging, the portion within it separates from the rest along the pre-cut line and follows the flap in the lifting movement. In this way an opening is formed in the wall of the packaging through which the products can be removed. The opening formed in this way can then be closed again by again applying the flap against the wall of the packaging, using for this purpose e.g. the peripheral portion of the flap which surrounds the portion of wall which the flap has taken with it in the lifting movement. This peripheral portion continues to be adhesive and is therefore capable of becoming attached to the wall of the packaging along the perimeter of the opening through which the products are removed.
  • the flap in question is normally associated with a seal which is capable of being ruptured as a consequence of action or an attempt at action intended to open the packaging: all this so as to render obvious any handling which might be attempted, particularly at points of sale, for unauthorised removal of individual products from the packages exposed for sale, and therefore to provide a disincentive.
  • the aforesaid flap is firmly welded to the body of the packaging along one of its sides. This prevents the operation of lifting the flap with respect to the opening (to permit the products to be taken out) causing complete detachment of the flap from the packaging, with obvious risks of the contents falling out/being dispersed.
  • the arrangement based on (total or partial) adhesive bonding of the flap to the body of the packaging is however in conflict with the fact that the substances with which the products are premoistened or preimpregnated, and/or other substances (e.g. creams, talcum powder or miscellaneous powders) frequently used together with the products, have an antagonistic effect against the adhesive materials used to ensure the possibility of opening and reclosing the flap.
  • substances with which the products are premoistened or preimpregnated, and/or other substances e.g. creams, talcum powder or miscellaneous powders
  • Packaging of the type specified above also tends to be used increasingly in industrial and even medical environments.
  • moving the protective flap away from the opening it is desirable that it should be possible (also for a large number of extraction cycles - in practice until all the products which are in the packaging have been removed) to close the flap protecting the opening in a condition which provides a seal with respect to the outside environment (e.g. to prevent moisture, bacteria, dusts, etc., from penetrating within the packaging).
  • the field of the possible application of the invention is not restricted to the area of humidified products (e.g. the so-called "wet wipes"), but may be extended to a variety of areas such as, e.g. the packaging of medical products and/or articles, etc.
  • the purpose of this invention is to provide an arrangement which is capable of overcoming the abovementioned disadvantages in the containers previously mentioned, regardless of the specific details of their construction.
  • receiving envelope indicates in general any body (whether rigid, semi-rigid, deformable or flexible, etc.) which is capable of performing a containment action, e.g. in order to receive within it moisturised hygiene-health products such as premoisturised or pre-soaked tissues or towels, with the possibility that these products can be selectively removed from the container through at least one opening provided in the wall of the container.
  • the words "sealing arrangement" as used below in the description and the claims which follow in general indicate any body which is capable of being selectively applied to the closure of the aforesaid opening with the possibility of therefore being at least in part separated from, moved away from or displaced from such opening so as to permit the products which lie within the packaging to be removed through the aforesaid opening.
  • a packaging for hygiene-health products such as pre-soaked or premoisturised tissues or towels is indicated as a whole by 1.
  • packaging 1 comprises a containment envelope 2 essentially comprising an envelope or bag of flexible material (e.g. coextruded polyethylene) which is capable of receiving within it a pack P of hygiene-health products.
  • the products in question may be premoisturised tissues or towels connected together in a chain of separable elements or arranged in accordance with a generally interleaved arrangement.
  • Envelope 2 may advantageously be of the "flow-pack" type, comprising a sheet which is closed to form a tube along a first line of longitudinal welding (not shown in the figures) with the subsequent formation of two lines of transverse welding 3.
  • an opening 4 which can be used to remove products P from the packaging.
  • Closure arrangement or flap 5 may be selectively removed by the consumer (in accordance with factors which are wholly obvious and known, which do not require to be illustrated in this context) from a closed position (shown in Figure 1), in which flap 5 closes opening 4, to a position in which the products can be removed (shown in Figure 2) in which flap 5 is lifted, displaced, detached or otherwise at least partly removed with respect to opening 4 so as to leave such opening 4 wholly or partly free so as to permit products P which lie within the packaging to be removed.
  • flap 5 is permanently attached to the body of envelope 2 (e.g. by being continuously heat welded) along one of its sides, indicated by 5a.
  • the flap may also be used to create opening 4 in the wall of envelope 2 when first detached from the packaging by means of the pre-cut line such as a punched or perforated line.
  • the portion of the wall of envelope 2 which flap 5, which is rendered adhesive on its surface which is intended to face envelope 2, has pulled with it on the first occasion when the pack is opened can be seen in Figure 2 and is indicated by 20.
  • the part of flap 5 to which the portion of envelope 20 is bonded is therefore no longer adhering, but the outer or peripheral portion indicated by 5b continues to be adhesive, for a variable length of time.
  • microhook is used here to indicate, in its widest sense, attachment structures of the "hook and loop” mechanical type which are sometimes also referred to as “overlap” closures, or in most common use are simply referred to by the trade name of "Velcro”.
  • the aforementioned closure devices may in their most conventional and ordinary form take the form of two complementary complexes (the hooks and the loops or complementary areas of hooks and loops) located on two joinable complementary members which are capable of being attached (e.g. by bonding or heat welding) to both parts of the closure which are intended to be connected. It is likewise known, however, that alternative arrangements provide for the possibility of using laminar structures, preferably functioning as loops (therefore also materials which are wholly or partly capable of constituting the body of envelope 2 or flap 5) by a locally apertured structure (which is typically hairy or "tufted") which is capable of defining a sufficiently engaging structure to achieve attachment with the hook members provided on the complementary part.
  • Typical examples of structures of this type are e.g. coatings of non-woven materials which are capable of being used e.g. to wholly or partly cover the outside sheets (the so-called back-sheets) of hygiene-health products such as nappies/diapers for babies, toddlers and incontinents - the latter being an application in which the use of microhook structures has already been tested and is starting to become quite widespread in order, e.g. to seal the product along the waistline by means of tabs provided for this purpose and/or so that the product can be closed up once it has been folded on itself after use.
  • the aforesaid mechanical coupling configuration using microhooks may in fact simply be achieved by using the material comprising flap 5 and/or the material comprising or coating envelope 2 as one of the complementary parts, in particular in the regions surrounding opening 4, in so doing making use of the intrinsic properties of the corresponding material (e.g. the fact that it comprises or is coated with a non-woven material of the tufted type) and/or through the effect of a specific treatment, which may be local, applied to the abovementioned material or coating, e.g. a heating treatment which induces the formation of a local porous or microporous open cell structure in the material or in a coating layer which is likely to constitute an anchoring formation for the complementary hook members.
  • a specific treatment which may be local, applied to the abovementioned material or coating, e.g. a heating treatment which induces the formation of a local porous or microporous open cell structure in the material or in a coating layer which is likely to constitute an anchoring formation for the complementary hook members.
  • hooks are mentioned within the scope of the term “microhooks” this should not in any way be interpreted in a sense limiting the conformation of the corresponding elements - it is in fact well-known in the art relating to closures commonly known as "Velcro” that the hook components may have different conformations from the conventional fishhook conformation, such as e.g. mushroom, hammer head, etc., conformations.
  • microhook closures have found application in a great variety of areas.
  • areas in the art in which microhook closures are used in conjunction with envelope or bag containers, even in special sectors such as e.g. furnishing, for the closure of cushion covers or pillow slips.
  • This invention is based on recognition of the fact that a microhook closure may be used to achieve attachment either wholly or in part between a closure arrangement such as flap 5 and the perimeter of an opening (such as opening 4 illustrated in the drawings), including in the specific field of application considered here where it is necessary to ensure, e.g. that the characteristic moisture content of the products P is preserved without undergoing any appreciable change over the course of time and/or to ensure adequate protection from external agents (dust, etc.).
  • the mechanical type closure may replace, even only in part, the conventional adhesive attachment between the closure arrangement (flap 5 in the example illustrated) and the corresponding opening (opening 4 in the example illustrated) avoiding the disadvantage due to the fact that the adhesive closure can lose its efficiency when it becomes contaminated e.g. by liquid and/or oily substances or by dusts which reduce its adhesive properties.
  • microhook closure is essentially defined by two strip members 6, 7 which extend continuously or discontinuously along the perimeter of opening 4 and along the corresponding portions of flap 5, therefore, in the embodiment illustrated, along and in an intermediate position within the external or peripheral portion 5b.
  • the latter arrangement may be suggested (essentially in relation to considerations of complexity and cost of construction) in such applications where the two complementary parts 6, 7 forming the microhook closure are constructed in simplified form, e.g. in the form of two pairs of complementary strips located on the two sides of opening 4 corresponding to the longitudinal direction of packaging 1.
  • a choice of this nature may be suggested e.g. by the need to apply the said strips "in-line" during the process of forming the envelope in the context of a packaging line of the flow-pack type.
  • one of the parts of the microhook structure may directly comprise the outer surface of envelope 2 in the region surrounding opening 4 or a coating applied thereto. It is however obvious that only a restricted portion surrounding opening 4 in this envelope is intended to act effectively together with the complementary members borne on flap 5 - therefore only the width of the region in which there is actually cooperation between the complementary elements will be taken into account.
  • this term also comprises any treatments applied to such components such as e.g. and without any intention of restriction: the application of soaking liquids, surface coatings and/or treatments designed to change the physical properties (e.g. providing surface softness) and/or chemical properties of the elements, including the application of agents having an antibacterial function.
  • the packaging itself in practice constitutes a kind of sealed envelope or bag in which products P are contained.
  • the wall of the envelope so formed is so to speak locally “nicked” by the punching or perforation defining the perimeter of opening 4.
  • the aforesaid punching or perforation however produces openings which are barely pervious, if not blind and in any event of very reduced clear cross-section.
  • a leaktight seal over the openings in question is provided by the central portion of flap 5 which is adhesively applied to the wall of the envelope corresponding to the region where opening 4 will be formed.
  • microhook closure 6, 7 has an effect of a synergistic type in comparison with seals of the adhesive type. This insofar as the microhook closure bears the greater part of the stresses which would tend to detach flap 5 from the envelope even when the adhesive attachment power weakens.
  • the adhesive attachment can therefore ensure an effective seal even when the said attachment has become weak to a point where the adhesive attachment alone is no longer sufficient to hold flap 5 against envelope 2.
  • tab 5 may also reduce completely or substantially completely. Even under these conditions, when flap 5 is closed against opening 4, a sufficient seal against the exterior (and the necessary captive effect which retains flap 5 against the wall of the envelope) will continue to be ensured by microhook closure 6, 7 which is substantially refractory with respect to phenomena (contamination by liquids and/or dusts in particular) which reduce the adhesive bonding capacity of flap 5 with respect to envelope 2.
  • the mechanism described effects a possible graduation in the sealing characteristics which corresponds precisely to the requirements of use: an absolute seal at the time of initial packaging (with the possibility of providing long storage periods without the risk of any kind of deterioration) and the possible gradual reduction in the adhesive sealing component as consumption of the products proceeds, with the possibility of relying upon a synergistic effect from the microhook closure. In all of this it is however possible to always count on the sealing component deriving from the presence of such a closure.
  • closures of the type described are very suitable for association with closure seals (e.g. adhesive labels applied partly to the outside of flap 5 and partly to the immediately adjacent region of envelope 2) which makes it possible to check (in a known way, through the effect of tearing the label) that the packaging has been opened at least once. Obviously all of this has the intention of indicating any improper handling of the packaging.
  • closure seals e.g. adhesive labels applied partly to the outside of flap 5 and partly to the immediately adjacent region of envelope 2
