The present invention relates generally to the field of packs/packaging, and in particular to outer containers suitable for retaining internally internal containers which may be dispensing packs/packaging.
It is desired to provide inexpensive re-useable dispensing packs, which offer the user the opportunity to partially dispense the contents of a container and store the remainder for later use. The user can dispense as much of the contents as required and then re-close (or reseal) the pack to store the contents for a future use. Re-sealing the pack is important particularly for materials, which are sensitive to their environment for example products, which are sensitive to air, moisture and/or light. It is desirable to provide the aforementioned sensitive material in a container and/or pack that will prolong the usable life of the product by protection from environmental conditions. Also for consumer-oriented products, it is desirable to provide a display friendly packaging which appeals to the consumer and which can be readily displayed by a retailer, particularly for point of sale display.
There exists a requirement for a low cost multi-use pack. While the present invention can also provide a packing for a single use or “one shot” disposable pack it is intended primarily for providing a pack which can be used on a multiplicity of occasions and over time.
The present invention provides a low cost multi-use pack. In particular it is desired to provide a combination pack, which is suitable for storage of environment sensitive products such as adhesive and other curable products. It is also an object of the invention to provide an outer container for use in such packs.
To this end, the invention relates to an outer container for holding an inner container in particular where the inner container has a sensitive product. The outer container comprises at least one of a moveable display board; retaining formations for retaining a hygroscopic element; or a stand for gripping the base of the inner container to retain it in an upright position. The invention also relates to a combination pack comprising the inner container retained in the outer container, particularly where the inner container holds a moisture sensitive product such as an adhesive.
The present invention will now be described in more detail with reference to the following Figures:
In particular the present invention has certain aspects as set out below.
A first aspect of the present invention provides (an outer) a container (for retaining an inner container), the (outer) container having a front display side and a rear side comprising:
The object or material is desirably an inner container.
A second aspect of the present invention provides an outer container for retaining an inner container with a dispensing end and a base end, the outer container comprising:
The invention relates in a third aspect to a combination pack comprising outer and inner containers wherein the inner container is retained in the outer container,
It will be appreciated that all aspects of the invention may be utilised in combination or in any suitable sub-combination.
In particular the features of the outer containers from the first and second aspects of the invention may be combined as desired in particular to provide a display board and a stand within the same construction and the present invention relates to such a construction and also to a combination pack comprising such an outer container.
The features of the outer container from the first and third aspects may also be combined as may be the features of the outer container second and third aspects.
This invention also relates to a combination pack comprising an outer container with any one of the combinations of features described above and an inner container.
The following description will describe features of the aspects of the invention described above and applies as appropriate to any aspect or combined aspect(s) which are employed.
Desirably the outer container has a base end and a top end and the opening is at the top end thereof. The base of the outer container is desirably arranged to maintain the outer container in a standing position when placed in an upstanding position on the base thereof. The base will also support the combination pack i.e. when the inner container is in situ within the outer container. It is also desirable that the container is constructed of transparent or translucent material. For example the outer container may be constructed of a natural or coloured plastics material (as discussed in more detail below).
Desirably the outer container is made of a rigid material. Forming the outer container in this way ensures that the inner container cannot be unintentionally squeezed by inadvertent pressure.
In a preferred arrangement the closure for the mouth of the outer container takes the form of a lid or cap which is mounted on the container body. Suitably at least one flexible hinge is provided between the container body and the lid. The hinge portion may be formed by a piece of flexible plastics. Optionally the hinge is reinforced suitably by provision of one or more reinforcing pieces on the hinge. In one construction it is desirable that the lid opens to one side of the container, i.e., that the flexible hinge is provided on a side wall of the outer container which is located between the front display side and the rear side thereof. Desirably the lid is a snap-fit to the container. A grip (a hand grip such as a thumb grip) may be provided on the lid for ease of opening and closing of the lid.
In one arrangement, the underside of the closure has formed thereon a stand, which comprises a slot into which the base of the inner container can be placed. The stand may be formed by upstanding members on the underside of the closure. Desirably the upstanding members form opposing grips for gripping opposing sides of the base of the inner container. In one arrangement two pairs of opposing grips are provided on the underside of the closure for gripping the base end of the inner container at positions spaced apart from each other. In particular it is desirable that the stand is arranged (to form a slot) for engaging the base end of an inner container, which has been formed by crimping.
Desirably the closure has a continuous upright member on the underside of the closure, which together with an outer rim on the closure forms an annular channel between the continuous upright member and an inner wall of the rim of the closure. When the mouth of the outer container is closed by the closure, a rim about the mouth of the outer container seats into the channel on the underside of the closure thereby providing an airtight seal between the closure and the outer container. Desirably, the outer container further comprises a rim which prevents the closure from being pushed too far down the container body when the closure is covering the mouth of the outer container.
Desirably the retaining formations for retaining the hygroscopic element on the outer container are provided on the underside of the closure. The hygroscopic element is desirably a desiccant material, which is in a pre-formed shape. The retaining formations are arranged to grip and engage the pre-formed desiccant material. The desiccant material may be of any known type though desiccant material formed of multiple layers of fibrous or polymer materials or molecular sieves are desirable. Desirably however it is the form of a pellet or tablet which can be gripped between the retaining formations. For example the pre-formed desiccant material can be in a generally cylindrical shape. Suitable pre-formed desiccant materials sold under the trade name POLLY DESICCANT are available from the following commercial source: Shanghai Polly Technology Development Co., Ltd. Shanghai, China and as advertised on the website: www.pollydesiccant.com. These desiccant materials are generally of the fibrous type. Desiccants of the molecular sieve type are available from Süd-Chemie with various facilities including one in New Mexico and from their website: www.sud-chemie.com. Desirably, the desiccant is in the form of a desiccant capsule. The desiccant may be for example a desiccant capsule comprising a silica gel held in a plastics (for example polypropylene) shell and covered with a cardboard disc.
Desirably, the top face of the closure may comprise a raised area such as a raised button. On the raised area information for the end user may be provided. In one embodiment the information area may be located directly above the hydroscopic element retainer. The raised area may have user information formed permanently therein such as by moulding—alternatively it can form a receiving surface for a sticker or label or the like conveying information for the end user. In general the raise area will operate as a push button upon which a user will press to close the closure.
Desirably the stand for receiving and gripping the base end of the inner container are formed integrally with the retaining formations for retaining the hygroscopic element. In one arrangement the retaining formations are formed by opposing C-shapes (spaced apart and facing in opposing directions).
In one arrangement a snap-lock is arranged between the display board and the outer container to lock the display board in the first (display) position (—against movement about the hinge portion). Suitably the hinge portion is a flexible hinge. The or each flexible hinge may be reinforced (as described above for other hinges). In one arrangement two flexible hinges are provided at spaced apart positions. In such a construction it is desirable that the snap lock arrangement is located between the spaced apart hinges. In this way substantial manual pressure must be applied about the hinge portion to overcome the snap-lock and move the display board into the second position. Movement between the first and second position will typically involve movement about the hinge portion through approximately an angle of 180 degrees or greater.
Desirably the at least one hinge portion is provided at one (lower) end of the display board. Further it is desired that the at least one hinge portion attaches the display board to the outer container at a position proximate to or at the top end of the outer container. In a first position of the display board in this construction the display board extends substantially beyond (and suitably above) the outer container. In this way the display panel is clearly visible to a user.
Desirably the display panel and the outer container are provided with interengaging formations which (when engaged) hold the display panel in the second position.
Further in one construction an aperture is provided in the display panel. The aperture may function as a display hanger for hanging the outer container on a display shelf or the like. The aperture is desirably located proximate to the (top) end of the display board away from the (bottom) hinged end.
The interengaging formations may be a projection on the display panel and a rim on the outer container. The rim may also have attached thereto the hinge between the closure and the outer container and the hinge(s) between the display board and the container.
In one construction a tamper evident feature may be provided between the display panel and the outer container. In particular the tamper evident feature could be provided between the closure and the display panel. If either the closure were opened or the display panel were moved a frangible connection between the two would break indicating tampering with the product. The tamper evident feature may be alternatively or additionally provided between the closure and the top end of the container body. In particular the tamper evident feature could be a plug (inserted through the closure and the top end of the container) and if the closure were opened, a frangible connection (formed by the plug) between the closure and the top end of the container body would break indicating tampering of the product. The plug itself may break or the closure and/or the top end of the container may be left with open apertures indicating that tampering (removal of the plug) has taken place.
The tamper evident feature could additionally or alternatively be a frangible connection formed by a tear-way strip. The strip could be connected to the closure and the top end of the container. The strip may be torn away from the closure and the top end of the container indicating thus that the container may have been opened, for example that tampering (removal of the tear-away strip) has taken place. The tear-away strip may be fully removed from the closure and container. However in an alternative embodiment the tear away strip may remain (partially) connected to the closure or the top end of the container. Desirably, the tear-strip may be arranged so that it is frangibly connected to (the top end of) the container body. For example the tear-away strip may be connected to the closure or the top end of the container by one or more connection pieces arranged at one or more connection points. In this arrangement, the closure may be retained in a closed position by at least one retaining portion on the tear-strip.
In one arrangement the tear-away strip is connected to the container body and has retaining portions which extend over the closure to retain the closure in a closed position. In such an arrangement it is possible that the tear-away strip is connected only to the container and not the closure. In one particularly desirable arrangement the tear-away strip extends circumferentially about the mouth of the container. Suitably the tear-away strip extends from the front display side about one side to the rear side, for example to a position proximate a hinge for the display board. Desirably the tear-away strip is frangibly connected to the container in such a way that a lip on the closure (for example a lip intended to be used as a grip such as a thumb grip,) is not obstructed by any part of the tear-away strip or any frangible connection between the container and the tear-away strip when the strip is removed. Desirably therefore any connecting pieces between the tear-away strip and the container come away with the strip when it is removed. This may include a lip portion on the container. This has the advantage of leaving an exposed lip on the closure which can be used to open and close the closure as desired.
Desirably, the tear strip may comprise a pull tab. The pull tab may be formed by a region of the tear strip that is not connected to the top end of the container and/or the closure. The pull tab may aid the end user in attaining a grip on the tear-strip for manual removal of the tear-strip
In order to avoid the display panel falling too far forward at least one stop may be provided between the display panel and the outer container, and in particular the closure therefor. In one embodiment there may be two stops provided between the display panel and the closure. Preferably the stops are arranged so that they do not interfere with the movement of the display panel between the first and second position. In one construction the stop(s) may be a (wedge shaped) protrusion from the display panel. Desirably, the stop(s) may be located on the display board above the hinge(s). The stops may engage with a rim on the outer container or the closure to prevent the display panel from falling too far forward.
One or more inner containers could be provided in a single outer container. Further the combination pack of the invention may include, as part of a kit, a dispensing nozzle or cannula adapted to fit the inner container and aid the application of product dispensed therefrom. The dispensing nozzle or cannula may be particularly useful with curable products such as cyanoacrylates.
One or both of, and desirably both of, the inner or outer containers can be moulded as a single piece for example from plastics material, thus making an integrally formed container which is relatively low cost to produce.
Desirably the outer container is also moulded as a single piece for example from plastics material, thus making an integrally formed container which is relatively low cost to produce. Apart from the body and closure the moulded piece would desirably include as appropriate the display board, the stand on the underside of the closure or the retaining formations as appropriate to the aspect(s) of the invention being adopted.
It is desirable that the inner container holds within its housing an environmentally sensitive product as an adhesive product. In particular it is desirable that the inner container holds within its housing a cyanoacrylate adhesive. Provision of the hygroscopic element within the outer container helps to increase the usable lifetime of an adhesive stored within the combined pack.
It will be appreciated that the inner container is removed from the outer container before use.
A suitable inner container is the container described and shown in International Patent Application No. PCT/IE01/00078 (Publication No. WO 01/94213) the entire contents of which are incorporated herein in their entirety by reference. In particular the inner container useful with the various aspects of the present invention may comprise a dispensing nozzle assembly with a re-useable break-off (or break-away) closure in the form of a cap. The nozzle assembly may be attachable to a container or integrally formed therewith. The nozzle may thus be closed with the cap after the cap has been broken off. The nozzle may be attachable to or integrally formed with a container and the containers contents are thus protectable by the re-useable cap. Snap-fit or other interengaging formations on the cap and the container may be used to retain the cap in place for storage.
The inner container according to any aspect of the present invention is desirably a hand-held phial. The phial may be constructed of deformable plastics so that it may be squeezable (by manual pressure and in particular finger pressure) to express product. Optionally the phial may be constructed of clear or translucent plastics. The plastics material can be sufficiently translucent to allow the level of product within the container to be determined by external viewing (through the sides of the container).
As can be seen from
The tear strip comprises a pull tab 30. The pull tab 30 is formed by a region of the tear strip 21A that is not connected to the top end 13 of the container body 1 and/or the lid 2. The pull tab 30 will assist the end user in securing a grip on the tear-strip 21A.
The words “comprises/comprising” and the words “having/including” when used herein with reference to the present invention are used to specify the presence of stated features, integers, steps or components but does not preclude the presence or addition of one or more other features, integers, steps, components or groups thereof.
It is appreciated that certain features of the invention, which are, for clarity, described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the invention which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable sub-combination.
