Abstract
A container 100 moveable, when squeezed, between a flat first configuration and a second configuration comprises: first and second faces (110, 120, fig. 9) joined at first and second opposing sides (102, 104, fig. 12B), and at third and fourth opposing sides (106, 108, fig. 13A); a slit 122 extending across the second face with an apex being closer to the fourth side than end-points of the slit are; a first line of weakness (1, fig. 7) on the second face, extending away from the slit towards the third side; a second line of weakness (2) on the first face, extending from the fourth side, wherein the first and second lines are straight, parallel to the first and second sides, and aligned with the slit apex; and a third line of weakness (3) on the first face, having end-points by the fourth side, and extending away from that side therebetween, further than the slit. The faces bend along the lines of weakness in the second configuration. The apex may be a single turning point or a straight line portion parallel to the third edge. The apex may be located centrally with respect to slit length.
Description
CONTAINER
The present invention relates to a container, a web for forming a container, and a method of using a container. In particular, but not exclusively, the present invention relates to a packet which can be folded flat in a first configuration and then squeezed so as to adopt a second configuration, with an opening of the container being arranged to widen when squeezed to facilitate insertion of an item.
The skilled person will appreciate that placing an item to be transported in a traditional paper envelope may lead to a discontinuous shape which may lead to a risk of tearing or other damage during handling.
Providing a padded envelope or box may require increased storage space when not in use, and would also increase postage costs if the envelope or box is to be distributed by mail prior to use. Thc skilled person will appreciate that small and delicate items may present a particular issue; for example, an item may be too small to be safely or reliably handled by a postal service, or small enough that it could easily be lost. Putting such an envelope into a large box or envelope might result in deleterious movement in transit, excessive packaging requirements, and/or ripping due to a discontinuous shape around the item catching processing machinery or the likes.
It is desirable to have a container that can be folded flat, for example for ease of distribution or storage, and then easily be reconfigured to contain a three-dimensional item. Such a container is disclosed in the applicant's granted patent, EP3597550. However, difficulties remain for insertion of an item into the container in the second configuration -a reconfigurable container with improved case of item insertion is therefore desired.
According to a first aspect of the invention, there is provided a container arranged to receive an item and comprising: first and second faces joined at a first side and at a second side opposite the first side, and joined at a third side perpendicular to the first and second sides, and at a fourth side opposite the third side; an opening, the opening comprising a slit in the second face extending across the second face, between the first and second sides, in the region of the fourth side, with an apex of the slit being closer to the fourth side than end-points of the slit arc; a first line of weakness located on the second face, the first line of weakness being straight and extending away from the slit towards the third side, parallel to the first and second sides and aligned with the apex of the slit; a second line of weakness located on the first face, the second line of weakness being straight and extending from the fourth side, parallel to the first and second sides and aligned with the apex of the slit; and a third line of weakness located on the first face, the third line of weakness having end-points near or at the fourth side, the third line of weakness extending away from the fourth side between the end points, and wherein the third line of weakness extends further from the fourth side than the slit, such that an apex of the third line of weakness is on the far side of the slit from the end points of the third line of weakness.
The container is moveable between a first configuration in which the first and second faces are flat such that the container is at least substantially flat, and a second configuration in which the first and second faces are bent along the lines of weakness, so providing a volume within the container between the first and second faces.
The container is arranged to adopt the second configuration when a pressure is applied to the first and second sides, and the opening is arranged to allow an item to be inserted into the volume when the container is in the second configuration.
Thc first, second, and third lines of weakness detailed above are arranged to cause the container to bend so as to widen the opening, when moved into the second configuration. Additional lines of weakness may also be present to facilitate bending of the container into the second configuration. The container may be otherwise as disclosed in the applicant's granted patent, EP3597550, but with the slit and lines of weakness as described herein.
Thc pressure may be applied by squeezing the container, for example between a finger and thumb. The container may be described as a pop-up container, as the container -P0Ps up-into the second configuration when the pressure is applied.
It will be appreciated that each line of weakness may or may not be weakened along the full length of the "path" as described for each, or may not be evenly weakened along that path. For example, whereas scoring or pre-folding of card may be used to provide even weakening, perforation naturally creates variations in weakening at and around each hole. Further, only a portion, or multiple portions, of the path may be perforated, scored, or otherwise weakened. For example, the third line of weakness may comprise one or more weakened sections along that path -for example two, unjoined, straight line weakened portions extending away from the fourth side, and angled towards each other such that distance between the straight line portions decreases as distance from the fourth side increases. Alternatively, a single weakened section may be provided, optionally in a V-shape or U-shape, with the "arms" of the V or U extending towards, but not reaching or closely approaching, the fourth side. The weakened section(s) may be selected such that the container bends at least approximately along the path, guided by the weakened sections, even when the whole of the path is not weakened. Each line of weakness is therefore a path along which bending of the container is facilitated, whether or not the entire length of that line is weakened. In some embodiments, the entire path length of each line of weakness is weakened, optionally evenly.
The first line of weakness may have an end point near or at the slit.
The container may have a negligible height in the first configuration; it may be substantially flat. There may be only a negligible space, or no space, between the first and second faces The container may have a non-negligible height in the second configuration. There may be a non-negligible space between the first and second faces. The skilled person will appreciate that the container design may provide a non-negligible height along most, if not all, of the container's length, and that this may reduce the risk of the container being mistakenly identified as a flat envelope by mail sorting/handling machinery (and handled inappropriately as a result).
Once an item is placed within the container and the pressure on the sides is released, the container may relax into an intermediate configuration having a height/shape between that of the first configuration and the second configuration. The container may be described as self-adjusting; when the item is placed inside, the tendency of the container to return to its original shape (the first configuration) may cause the container to close/reduce in height until it touches the top and bottom surface of the item placed inside it -therefore, the container may become as slim as it can be whilst retaining its protection and maintaining the location of the item inside. Advantageously, the size reduction may improve packing efficiency for transportation and storage. The height may vary smoothly along the length of the container in the intermediate configuration -in particular, the bends along the first, second, and third lines of weakness to widen the opening may flatten out, returning the opening to its slit shape. Advantageously, smooth variation in height along the container in this intermediate configuration may reduce the chance of the container catching or tearing in transit.
The shape and/or size of the slit may be selected based on dimensions of the item to be inserted into the container.
The slit may be positioned and shaped such that it opens automatically when the container is moved into the second configuration.
All sides of the first face may be connected to corresponding sides of the second face -for example adhered thereto or formed from a fold in a single sheet -such that the item can only bc inserted into the container through the slit.
The slit may have a single turning point, that urning point being the apex.
Alternatively, the slit may have a straight line portion parallel to the third edge, the straight line portion providing the apex.
The apex may be located centrally with respect to slit length.
The apex may be located centrally with respect to container width (being equidistant from the first and second sides).
The slit may have a first end near the first side and a second end near the second side, and the span between the first and second ends of the slit may be at least 70% of the distance between the first and second sides (i.e. at least 70% of container width).
The slit may be arranged such that the apex of the slit is spaced from the end-points of the slit by a distance of at least 10% of the distance between the third and fourth sides at least 10% of container length).
The slit may be curved, at least in part. Alternatively, the slit may be formed by two or more straight lines.
The slit may comprise, or consist of, two, angled, straight line portions meeting at a corner, he corner forming the apex, such that the slit has a V-shape The slit may comprise, or consist of, three conjoined straight-line portions, the middle straight line portion being parallel to the fourth side and forming the apex, such that the slit has a trapezoidal shape. Alternatively, the first and third portions may be curved, with a straight central portion forming the apex, or the first and third portions may be straight, with a curved central portion.
Thc slit may comprise a curved (e.g. circular) hole at each end-point. The hole may be small compared to slit length, optionally having a radius of 1 mm or less. The hole may serve to distribute forces at the slit ends when the container bends, so potentially reducing the chance of tearing.
The container may further comprise a fourth line of weakness located on the second face. The fourth line of weakness may be provided to facilitate bending of the second face along the first line of weakness. The fourth line of weakness may have end-points near or at the end points of the slit. The fourth line of weakness may extend away from the slit and towards the third side of the container between its end points. The fourth line of weakness may be V-shaped, or curved. As for the third line of weakness, in some embodiments, the fourth line of weakness may comprise or consist of a single weakened section in the vicinity of the apex, forming the apex, and/or two straight line weakened portions along the described path from the fourth side, rather than the entirety of the path length being weakened Thc first and second lines of weakness may be aligned such that, in the first configuration, they are in contact along their lengths. The first and second lines of weakness may extend to the same distance from the fourth side.
The third line of weakness may be at least partially curved, for example comprising two straight line portions joined by a curved apex portion. The third line of weakness may be V-shaped.
The third line of weakness may comprise two straight line portions each extending towards the other, away from a respective end-point of the third line of weakness. Each straight-line portion may extend away from the fourth side at an angle of around 54° to the fourth side.
In such embodiments, the two straight line portions may be joined by a curved portion which extends between the two and provides the apex of the third line of weakness. Alternatively, the two straight line portions may meet at a point, the point providing the apex of the third line of weakness The third line of weakness may have a single apex, the single apex optionally being the only turning point of the third line of weakness.
The container may further comprise a pair of internal flaps positioned between the first and second faces and spaced inwardly from the first and second sides. In the first configuration, the internal flaps may be flat and parallel to the faces, and in the second configuration the internal flaps may be at an angle with respect to the first and second faces and arranged to act as spacers between the first and second faces, so providing a volume within the container defined by the first and second faces and the flaps. The opening may be arranged to allow an item to be inserted into the volume defined by the first and second faces and the flaps when the container is in the second configuration. In some embodiments, the flaps may cause the container to remain in the second configuration after a force applied to move it from the first configuration into the second configuration is removed.
In embodiments with internal flaps, the internal flaps may be spaced so as to form a channel therebetween arranged to receive the item when the container is in the second configuration. The channel may have a width of between 4 cm and 1 cm, and optionally of around 3 cm. The channel may be centrally located with respect to the width of the container. The skilled person will appreciate that the internal flaps may therefore prevent or limit rotation of an elongate item, and/or limit movement of the item.
The internal flaps may provide some resistance against the container returning from the second configuration to the first configuration.
The internal flaps may provide some resistance against the central region of each face bowing inwardly between the first and second sides when the pressure is applied to the first and second sides.
The internal flaps may extend along substantially the full length of the container between the slit and the closed end region.
The container may further comprise a flap support structure arranged to support the internal flaps. This support structure may comprise a protruding portion arranged to lie between the end portion of the first face nearer the opening and the second face. The end portion of the first face may be adhered to the second face only along an edge, so allowing the protruding portion to slide beneath an end portion of the second face; between the first and second faces, in the end region The end portions may therefore provide a limitation on flap movement.
In the closed end region (i.e. the end region further from the opening), the flap and flap support structure may be arranged to end a short distance before the closed end. The skilled person will appreciate that the container may be opened to retrieve the item by cutting off the end of the container. It may therefore be beneficial to keep the number of layers of material adjacent the closed end to a minimum for case of cutting. The shape of the internal flaps and flap support structure may be selected so as to have inclined angles to facilitate keeping the amount of material in the cut zone when the container is opened low. This design feature may assist in providing a minimal mechanical loading on a cutting device used to open the container. The skilled person will appreciate that a channel between the internal flaps may keep the item at least substantially aligned with the container, which may facilitate the item sliding out when the container is cut open.
Thc height of the internal flaps may be selected to at least substantially match the height of the item.
Thc spacing between the internal flaps may be selected to at least substantially match the width of the item. The length of the flaps may be selected to extend beyond the length of the item, so as to reduce the risk of a discontinuous shape around the item making the item vulnerable to damage, e.g. by mail-processing apparatus.
Thc container may be arranged to receive an item. The item may be a sample container, for example a medical sample vial arranged to receive a faecal, cervical, blood or urine sample. Such items may be small, relatively delicate and easily lost. The container may therefore be sized to receive such an item, optionally engagingly. The item may be an 0C-Auto sampling bottle 3, article number 20000790, available from Clindia (12W/wtys:. iiiiprOuct/10Thc-iquto piriplirifizbcple73_html) -the container may therefore be arranged to receive a faecal sample bottle such as an 0C-Auto sampling bottle The container may be arranged to contain a fecal sample bottle.
The container may further comprise a closure, such as a sealing flap. The closure may comprise a flap arranged to cover the opening. The flap may extend from an end region of the first face (or the second face) and be arranged to be folded onto the face comprising the opening slit to seal the container. The closure may comprise a pressure sensitive bonding agent. The pressure sensitive bonding agent may cover the entirety of the opening area. Thc closure may provide a hermetic seal for the container whcn sealed. In embodiments in which the closure extends from the fourth side of the container, the second line of weakness may continue / extend across the closure.
The container may comprise a sealing flap extending from the fourth side and arranged to be folded so as to cover the slit and thereby seal the container.
In the first configuration, the container may have substantially only two faces (having a negligible height). The container may resemble a traditional flat envelope The container may be substantially rectangular in the first configuration.
Each of the first and second faces may comprise: a first-side line of weakness extending between, and tending inwardly between, end regions of the first side, the first-side line of weakness dividing a first edge region of the face from a central region of the face; and a second-side line of weakness extending between, and tending inwardly between, end regions of the second side, the second-side line of weakness dividing a second edge region of the face from the central region of the face.
In such embodiments, in the second configuration, the first and second edge regions are at an angle with respect to the central region of the faces -the container is bent along the first-side and second-side lines of weakness. A pressure may be applied to the first and second sides to cause this bending. In the second configuration, the central region of each face may be curved to accommodate the position of the edge regions.
In the second configuration, the first edge region of the first face and the first edge region of the second face may form a third face, and the second edge region of the first face and the second edge region of the second face may form a fourth face. The third and fourth faces may be at least substantially perpendicular to the first and second faces in the second configuration. The container may resemble a box in the second configuration. These first-and second-side lines of weakness may extend along at last substantially the full length of the container, and/or may be cmyed. The third and fourth faces may be lens-shaped; having a shape formed by two arcs joined at their end-points. The arcs may be circular arcs. The first and second sides may takc the form of lines (e.g. fold lines) in the first configuration. The lines may become centre lines of the third and fourth faces in the second configuration. The third and fourth faces may be flat/planar across the height of the container, or may be angled around the centre lines. The third and fourth faces may be curved (or folded so as to have portions at different angles) along the length of the container.
In such embodiments, an edge of a sheet of material forming the central region of the second face may be inwardly offset from the line of weakness. This may facilitate folding and/or reduce the risk of the edge of the sheet of material becoming unstuck with movement between configurations. For example, the first face, the edge portions of the second face, and a connection means to allow attachment of the central region of the second face may be provided by a single sheet folded to form the first and second edges. The central region of the second face may be provided by an hourglass-shaped sheet portion (which may or may not be integral with the first sheet). The hourglass shape may be curved (formed by two concave curves) or angled (formed by two V-shapes or two trapezia). There may be a spacing between the inwardly-tending edges of the hourglass and the lines of weakness, with the edges of the hourglass being closer to a central line along the length of the container; for example an offset of between 0.5 mm and 2 mm, and optionally of around 1 mm. This spacing may be provided by the connection means, which may take the form of a flap extending from the edge portion of the second face, on the far side of the line of weakness therefrom. The skilled person will appreciate that if these inwardly tending lines were matched instead of offset, the amount of force required to fold the pack may be increased. By providing an offset, folding along the line of weakness may be facilitated, so facilitating moving to the second configuration. The offset may allow a central region of the line of weakness to fold/crease more easily, and may aid the popping up of the container into the second configuration. Further, if exerting the pressure between the sides put pressure on the join (e.g. adhesive, such as glue or a heat-bonding coating) between the central region of the second face and the edge regions, the chance of delamination of the sheets may be increased. The offset may provide a lip shielding the join from direct pressure.
The container may further comprise an absorbent material adhered to an inner surface of the container. The absorbent material may be provided on an inner surface of the first face or of the second face. The absorbent material may be arranged to absorb any fluid leaked from the item, in embodiments with internal flaps, the absorbent material may be arranged to lie along the channel created between the internal flaps. The skilled person will appreciate that arranging the absorbent material within the channel may minimise height in the first configuration as the internal flaps may fold adjacent to the absorbent material and not overlap therewith.
The container may be a packet. The container may be made of card. The card may have a polymeric coating, for example providing a bio-polymeric bonding surface. The polymeric coating may provide water resistance. The polymeric coating may be used for thermal bonding of portions of the container during assembly.
According to a second aspect, there is provided a web for creating a container according to the first aspect from a single sheet of material.
The web may further comprise an absorbent material. The absorbent material may be adhered to an inner surface of the second facc. The strip of absorbent material may be referred to as an absorbent element.
In embodiments with internal flaps, the absorbent material may comprise a strip arranged between the internal flaps.
The sheet of material may be paper or card.
At least one face of the sheet of material may be coated with a coating. The coating may be a polymeric coating (optionally a bio-polymeric coating) The coating may be arranged to provide at least one of water resistance: and thermal bonding.

In the first configuration, the container 100 has a height (11) of less than 0.8 cm, and more particularly of 0.2 cm or less in the embodiment being described. The height may be the thickness of four lavers of the material used to make the container 100, which is card in the embodiment being described The skilled person will appreciate that the container may have different dimensions in different embodiments (for example with a varying width as indicated by the broken lines in Figures 8 and 9, among others), and that the dimensions listed herein are provided by way of example only. For example, the width may be between 5 cm and 50 cm and the length may be between 5 cm and 50 cm. The length and the width may be equal in some embodiments. The height is small with respect to the length and width in all embodiments. For example, the height may be a maximum of 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, or 1 cm. The height may be defined by the number of layers of card overlying each other in the first configuration. The height may include a small amount of open space in addition to the number of lavers of card.
The container 100 has first 110 and second 120 faces. The first and second faces 110, 120 are joined along their sides so as to form a pocket 101 (i.e. an enclosed space or volume) therebetween, in which the item 10 can be received.
The container 100 has first and second sides 102, 104 along the length (L) of the container 100. The first side 102 is opposite the second side 104, and is parallel thereto in the embodiment being described. The skilled person will appreciate that, whilst the container of the embodiment being described is substantially rectangular (at least in the first configuration), other shapes may be used in alternative embodiments (e.g. trapezoidal containers) and the sides may be opposing but not parallel in such embodiments.
The container 100 has a third side 106 across the width (W) of the container 100. The third 106 side forms a closed end of the container 100 (i.e. the end of the container further from the opening 122). The third side 106 is perpendicular to the first and second sides 102, 104 in the embodiment being described.
The skilled person will appreciate that, whilst the container 100 of the embodiment being described is substantially rectangular, other shapes may be used in alternative embodiments (e.g. trapezoidal containers) and the third sides may not be perpendicular to the first and second sides in such embodiments.
The container 100 has a fourth side 108 across the width of the container 100. The fourth side 108 is located in an open end region of the container 100 (i.e. the end of the container closer to the opening 122 / the end region including the opening 122). The fourth side 108 is perpendicular to the first and second sides 102, 104 and parallel to the third side 106 in the embodiment being described. This may differ in alternative embodiments, as indicated above.
In the embodiment being described, a sealing flap 112 extends from the fourth side 108 of the first face 110. A fold line 108a is located on the fourth side 108 of the first face 110; the sealing flap 112 is connected to the first face 110 by the fold line 108a. The sealing flap 112 is arranged to fold over an end region of the second face 120 and to be adhered thereto so as to seal the container 100. The sealing flap 112 is arranged to cover the opening 122 of the container 100, which is described in more detail below.
In the embodiment being described, an underside 1 I 2a of the scaling flap 112 is provided with an adhesive (e.g. as a double-sided tape or coating). The adhesive may be contact-sensitive adhesive and/or moisture-sensitive adhesive. In the embodiment being described, the sealing flap 112 is provided with a full coverage of a pressure sensitive bonding agent to facilitate the opening 122 being hermetically sealed by covering the full area of the opening122.
In the embodiment being described, the first and second faces 110, 120 are adhered together in a region of the fourth side 108. The item 10 therefore cannot be inserted into the container 100 by insertion between the edges of the faces where they meet. Instead, a slit 122 in the second face provides the opening 122 In the embodiment being described, the slit 122 is curved. The curve has the approximate shape of half of an oval / a semi-ellipse. The span of the curve (at least substantially parallel to the width of the container) is greater than the maximum height of the curve (at least substantially parallel to the length of the container 100). The curve is symmetrical about a central line down the length of the container 100.
In the embodiment being described, the slit 122 has a span of 7.6 cm; i.e. around 76% of the width of the container 100. In alternative embodiments, the slit 122 may have a span of at least 70% of the container width. In alternative embodiments, the slit 122 may have a span of between 50% and 90%, and preferably between 70% and 90%, of the container width.
In the embodiment being described, the slit 122 has a maximum height of around 17 mm (slit "height" in this context referring to spacing between the end-points and another point on the slit, along the container's length, with the maximum being at the curve's apex); i.e. around 200% of the thickness of the item 10. In alternative embodiments, the slit 122 may have a height of between 150% and 400%, and preferably between 175% and 225%, of the container height, H. The skilled person will appreciate that the height of the slit should be sufficient to allow insertion of the item 10 when the container 100 is bent as described below, and should be preferably sufficiently short for the sealing flap 112 to be able to cover the entirety of the slit 122 and to allow space at either side of the slit such that a complete seal of the opening 122 can be provided by the sealing flap 112 The skilled person will appreciate that the length of the slit should be sufficiently long to allow insertion of the item 10.
In the embodiment being described, the slit 122 is arranged to automatically open when the container 100 is compressed/squeezed, and designed to provide a sufficient entry height for the item 10 in the second configuration.
The curvature of the slit 122 has been reversed as compared to that disclosed in the applicant's granted patent, EP3597550, such that the apex is closer to the fourth side 108 than the end-points of the slit are -it curves towards the nearest end of the container 100 instead of away from it. Whilst this change in curvature alone could make it harder to insert an item 10 into the container, with the upwardly-extending "flap" 120a of the opening 122 potentially catching on the item 10, the combination of this with the jaw-type opening described below, provided by the lines of weakness, facilitates item insertion. In particular, the change in orientation of the slit 122 may help to ensure that tape or another adhesive for the closure of the sealing flap is not exposed to the inside of the container 100, and therefore will not conic into contact with the item 10 and stick to it.
In alternative embodiments, the slit 122 may not be curved, or may only be curved in part. However, in every embodiment an apex of the slit (be that a vertex where two lines meet, a turning point of a curve, or a straight line portion of a slit with multiple different portions) is located closer to the fourth side 108, and in particular is the closet part of the slit 122 to the fourth side 108. For example, the slit 122 may be V-shaped, with a vertex closer to the fourth edge108 than either end-point of the slit is. Alternatively, the slit 122 may be trapezoidal in shape, with two angled portions each leading away from a respective end-point of the slit towards the fourth edge 108, and being joined by a straight line portion parallel to the fourth edge 108, the middle portion forming the apex. Preferably, the apex is centrally located with respect to the slit 122, and with respect to container width, W. Preferably, the two end-points of the slit 122 are equidistant from the fourth edge 108 / at the same distance along the length of the container 100.
In the embodiment shown in Figure 7, the slit 122 takes the form of an arc of a circle for the majority of its length, curving more sharply near its end points to form end regions at least approximately parallel to container length, L. The arc has a radius of 53 mm in the embodiment shown. The slit 122 has a span of around 75 mm, and is a circular arc for around 66 mm of that span, with the remaining 4.5 mm of span at each end of the central arc being covered by the non-circular arc end regions. Dimensions and curvature vary in other embodiments. The "height" of the slit 122 (spacing between endpoints and apex, parallel to container length, L) in the embodiment being described is around 17.5 mm. In general, the height of the slit 122 is at least 25%, and optionally at least 30%, of the slit span.
In some embodiments, each end of the slit 122 may terminate in a small hole (not shown) through the second face 120. The hole may have a radius of less than 1 mm, and optionally less than 0.5 mm. The hole may serve to distribute forces at the slit ends when the container bends, so reducing the chance of tears. In embodiments with a fourth line of weakness 4 as described below. the fourth line of weakness 4 may also have its end-points on these holes.
In the embodiment being described, the portion of the second face 120 between the slit 122 and the fourth edge 108 is arranged to lie on an inner surface of the first face 110. In the embodiment being described, at least some of the portion of the second face 120 between the slit 122 and the fourth edge 108 is adhered to the inner surface of the first face 110 in the region of the fourth edge 108, in particular in the central region, near the apex of the slit 122.
As such, once an item 10 is inserted fully through the opening 122, the slit edge formed by the portion of the second face 120 adhered to the inner surface of the first face I 10 may act as a lip I22a and may serve to restrain movement of the item 10 even if the container 100 is tipped up before the sealing flap 112 is closed. In the embodiment being described, the slit edge is not directly adhered to the first face 110, so the lip created in the second configuration may be slightly deeper than the material thickness of the lip.
The opening slit 122 is surrounded by one or more lines of weakness arranged to cause the container 100 to bend so as to widen the opening, when moved into the second configuration. This arrangement may be referred to as a jaw-type opening, and the lines of weakness may be referred to as "opening lines of weakness" to differentiate them from lines of weakness used for other purposes. The one or more lines of weakness may be formed by pre-folding or pre-creasing the material used to make the container 100 in the relevant places, and/or by deliberately thinning or otherwise weakening the material of the container 100 in those areas (e.g. by scoring, etching, and/or perforating it).
A first opening line of weakness 1 is located On the second face 120. The first opening line of weakness 1 is straight and extends away from the slit 122, towards the third side 106 of the container 100. One end-point of the first line of weakness 1 is located on/at the slit 122, and more particularly at the apex of the slit. The second end-point of the first line of weakness 1 is located closer to the third side 106 The first line of weakness I is parallel to the first and second sides and aligned with the apex of the slit 122, and so is centrally located with respect to the width of the container 100 in the embodiment being described. The first opening line of weakness 1 may extend for 20% to 60% of the container length. L. and optionally to a point around 40% of the length of the container 100 from the fourth side 108. The first opening line of weakness 1 has a length of around 5 cm to 6 cm in the embodiment being described.
The first opening line of weakness 1 is arranged to allow the "flap" 102a to fold outwards when the container 100 is squeezed, so forming a mouth or spout shape, facilitating insertion of the item 10. In particular, the apex of the flap 120a moves outwards, away from the first face 110.
A second opening line of weakness 2 is located on the first face 110. The second opening line of weakness 2 is straight and extends from the fourth side 108, parallel to the first and second sides and aligned with the apex of the slit 122. The second line of weakness 2 is aligned with the first line of weakness 1 such that they are almost collinear / are adjacent along their lengths in the first configuration. As the first and second faces 110, 120 are adhered together in the region of the fourth side 108, a line of weakness 2 may be visible on the second side 120, extending upwards from the slit 122 in the orientation shown, effectively continuing the first line of weakness 1, as can be seen in Figure 2. In embodiments in which the sealing flap 112 is provided by the second side 120, this line of weakness 2 may also be deliberately introduced to the second side to facilitate bending. The second line of weakness 2 extends past the slit 122, or at least past the apex of the slit. The second opening line of weakness 2 may extend for 20% to 60% of the container length. L. and optionally to a point around 40% of the length of the container 100 from the fourth side 108. The second opening line of weakness 2 has a length of around 5.5 cm to 6.5 cm in the embodiment being described, and optionally extends further towards the third side 106 than the first opening line of weakness 1 does. Thc second opening line of weakness 2 is arranged to allow the "rear" of the container to fold outwards when the container 100 is squeezed, so adding to the mouth or spout shape, facilitating insertion of the item 10. In particular, the central portion of the container 100 "above" the opening in the orientation shown! on and around the fourth side 108 of the container, moves rearward, away from the second face 120. The opening 122 may therefore have a substantially diamond shape if viewed from above / from the fourth side, looking towards the slit 122, with end-points of the slit forming two vertices of the diamond and the first and second lines of weakness forming the other two vertices.
A third opening line of weakness 3 is located on the first face 110. The third opening line of weakness 3 has end-points at or near (for example within 2 mm of) the fourth side 108 of the container, and an apex further from the fourth side 108. The third line of weakness 3 extends away from the fourth side 108 between the end points. The third line of weakness 3 extends further from the fourth side 108 than the slit 122, such that the apex of the third line of weakness 3 is on the far side of the slit 122 from the cnd points of the third line of weakness and from the fourth side 108. The apex of the third line of weakness 3 may intersect the second line of weakness 2 at or near an end of the second line of weakness 2 furthest from the fourth edge 108.
In the embodiment shown, the third opening line of weakness 3 comprises two straight line portions, each extending away from the fourth edge 108 at an angle, and a curved portion joining the two. The curved portion is aligned with the apex of the slit 122. In particular, an apex of the curved portion is aligned with the apex of the slit 122, and therefore also centrally located with respect to the width of the container in the embodiment shown. In alternative embodiments, the third opening line of weakness 3 may comprise two straight line portions which meet at a point, the point forming the apex of the line of weakness 3. The apex may again be aligned with the apex of the slit 122. In the embodiment shown, the angle between the straight line portions and the fourth edge is between 500 and 600, and more specifically is around 540.
In the embodiment shown, the end points of the third opening line of weakness 3, on the fourth edge 108, are spaced apart by a distance of?? mm. In various embodiments, the end points of the third opening line of weakness 3 may be spaced apart by a distance of at last 70%, and optionally at least 75%, of the container width, W. A fourth opening line of weakness 4, as sketched in dotted lines in Figure 7, may additionally be provided in some embodiments. This fourth line of weakness 4 may facilitate the bending of the flap 120a, playing a similar role to that played for the second line of weakness 2 by the third 3. The fourth opening line of weakness 4 of the embodiment depicted comprises two straight line portions meeting at a vertex at or near the end of the first line of weakness I furthest from the slit 122. The fourth line of weakness 4 may instead be curved, or comprise a curved portion (for example, having a shape similar to that shown for the third line of weakness), in other embodiments, or may not be present at all. A fourth line of weakness 4 may develop in use of the container 100, even if not initially provided.
Aside from the opening lines of weakness 1, 2, 3, in the embodiment being described, the first and second faces 110, 120 each comprise two further, inwardly-tending, lines of weakness 114a, 114b, 124a, 124b.
These lines of weakness may be referred to as side lines of weakness, to distinguish them from the opening lines of weakness.
The first lines of weakness II4a, I24a are adjacent the first side 102; one 114a is on the first face 110 and the other I24a on the second face 120. The first lines of weakness 114a, 124a each separate a first edge region 116a, 126a of the face 110, 120 from a central region 117, 127 of that face.
The second lines of weakness Ii4b, 124b are adjacent the second side 104; one 114b is on the first face 110 and the other 124b on the second face 120. The second lines of weakness 114b, 124b each separate a second edge region 116b, 126b of the face 110, 120 from the central region 117, 127 of that face.
Each face 110, 120 therefore comprises a central region I I 127 and two edge regions 116a, 116b, 126a, 126b In the embodiment being described, the side lines of weakness 114a, 114b, 124a, 124b extend along substantially the full length of the container 100. The edge regions I 16a, 116b, I26a, I 26b therefore also extend along at last substantially the full length of the container 100.
In the embodiment being described, the side lines of weakness 114a, 114b, 124a, 124b terminate approximately 5 mm from the fourth side 108 of the container 100. The gap, G. may facilitate sealing, preferably hermetic sealing, of the container. In the embodiment being described, the spacing between the end of the lines of weakness and the fourth side 108 is used to adhere the fourth edge region 108 of the second face 120 to the fourth edge region of the first face 110.
In the embodiment being described, the side lines of weakness 114a, 114b, 124a, 124b are curved. In the embodiment being described, the apex of each curve, which is the furthest point on the curve from the side 102, 104 it extends along, is around 6-8 mm from that side 102, 104. In alternative embodiments, the apex may be differently positioned, for example being between 3mm and 20 mm, and optionally between 5 mm and 10 mm, from the side. The skilled person will appreciate that the spacing chosen may depend on the size of the item 10.
The skilled person will appreciate that V-shaped side lines of weakness could be used in the same manner in alternative embodiments, optionally with a central fold-line across the width of the container 100, between apices of V-shaped lines of weakness. The skilled person will appreciate that trapezoidal side lines of weakness could be used in the same manner in alternative embodiments, optionally with fold-lines across the width of the container, and/or in other designs such as those disclosed in the applicant's granted patent, EP3597550. The skilled person will therefore appreciate that the inwardly-tending sides and lines of weakness may be curved, trapezoidal. V-shaped, or the likes in various embodiments, with the apex of the curve or V-shape, or the shorter parallel side of the trapezium, being further toward a centre line of the container 100than each extremity of the line of weakness.
In the second configuration, the container 100 folds along the lines of weakness, so creating third and fourth faces 170, 180 of the container 100. The envelope-shaped container of the first configuration therefore becomes more box-shaped, having a non-negligible height. In the embodiment being described, a height, H, of the container 100 between the apices of the pairs of lines of weakness along each side 102, 104 is around 1.5 cm in the second configuration. In the earlier design disclosed in the applicant's granted patent, EP3597550, this height between the apices of the pairs of lines of weakness along each side 102, 104 was the maximum height of the container 100 in the second configuration, and height decreased smoothly towards ends of the container 100. However, in the newer design disclosed herein, the "jaw"-type opening provides an increased height in the second configuration -which may be greater than or equal to the height mentioned above -in the region of the opening slit 122. The height between the apices of the pairs of lines of weakness along each side 102, 104 is, in many embodiments, the maximum container height in the intermediate configuration, in which the opening 122 can be closed / return to a slit shape whilst still providing a volume within the container 100 for the item 10.
Figure 8 shows a container 100 of an embodiment in a first configuration, in which the container is at least substantially flat. In this embodiment, the container 100 comprises internal flaps 130a, 1301,, as described in more detail below and in the applicant's earlier granted patent (EP3597550). The internal flaps 130 may allow the container 100 to remain in the second position even when the squeezing pressure is released.
The container 100 of the embodiment being described with respect to Figures 8 to 15 and 17 further comprises internal flaps 130a, 130b. The internal flaps 130a, 130b are located between the first 110 and second 120 faces. In the embodiment being described, the container 100 comprises a pair of symmetrical flaps; in other embodiments, the flaps 130a, 130b may not be symmetrical, or no internal flaps may be present. In the embodiment being described, the flaps 130a, 130b are substantially rectangular.
In the embodiment being described the internal flaps 130a, 130b are parallel to the length of the container 100. In alternative embodiments, the internal flaps may be differently angled.
In the embodiment being described the internal flaps 130a, 130b have a constant height along the majority of their lengths. In the embodiment being described, the internal flaps 130a, 130b have a height of around 1 cm. In alternative embodiments, the flaps may have a different height, for example between 0.5 cm and 3 cm. The height of the flaps may depend on the shape and size of the item 10 to be contained.
In the embodiment being described, the internal flaps 130a, 130b extend along at least two thirds of the length of the container 100. The skilled person will appreciate that the length of the internal walls is arranged to provide not only guidance and positioning for the item 10, but also to increase compression strength of the container 100 in the second configuration, and potentially also in the intermediate configuration.
In the embodiment being described, the internal flaps 130a, 130b are arranged to form Internal walls 130a, 130b in the second configuration, as shown in Figure 9, and to create a channel 131 thcrebetween to receive the item 10. In the embodiment being described, the item 10 is elongate and the channel 131 is sized such that the item 10 is retained at least substantially aligned with the length of the container 100; i.e. so that the item 10 cannot rotate by 90, and optionally not by more than 30 or not by more than 15' or 10'. The internal walls/flaps 130a, 130b are at least substantially perpendicular to the central regions of the first and second faces 110, 120 in the second configuration, and optionally also in the intermediate configuration.
In the first configuration, the internal flaps are parallel to the central regions of the first and second faces 110, 120, such that the container 100 can be substantially flat. Tn the second configuration, the internal flaps may act as spacers; separating the first and second faces 110, 120. The flaps 130 may maintain, or help to maintain, a gap between the first and second faces 110, 120.
The internal flaps 130a, 130b are each connected to a flap support structure. The flap support structures are arranged to hold the flaps in place and to facilitate movement of the flaps between the first and second configurations.
In the embodiment being described, each flap 130a-b is connected to two shaped sheets 132a-b, 134a-b.
The first shaped sheet 134a, 134b is connected to the respective internal flap 130a, 130b along a first line of weakness 133a, 133b. In the embodiment being described, the line of weakness 133a, 133b is a perforated line; in other embodiments folds, scores, or the likes may be used instead of or as well as perforation.
In the embodiment being described, the first shaped sheet 134 is adhered to the internal side of the second face 120 of the container 100 when assembled. The first shaped sheet 134 serves to mount the flaps 130 to the container 100.
The first shaped sheet 134 serves to rotatably mount the internal flap 130 within the container 100 at a position spaced from an edge 102, 104 of the container 100. The internal flap 130 is rotatable with respect to the container 100 about the fold line 133. In the embodiment being described, the first shaped sheet 134 extends between the internal flap 130 and the line of weakness 124 -the skilled person will appreciate that this may facilitate making the container 100 from a single sheet of material, as described below. In alternative embodiments, the first shaped sheet 134 may be or comprise one or more strips adhered to the internal side of the second face 120 of the container 100.
In the embodiment being described, an edge of the first shaped sheet 134 nearest the fourth side 108 of the container 100 (the open end) is shaped so as not to cover the slit 122. In the embodiment being described, the edge of the first shaped sheet 134 nearest the fourth side 108 of the container 100 is curved -in alternative embodiments, the edge could be straight and optionally angled. In the embodiment being described, the edge nearest the fourth side 108 of the container IOU is arranged to lie around 2 mm within the opening 122/from the slit 122 when assembled. The skilled person will appreciate that it may be advantageous for the shaped sheet 134 not to extend to or past the slit 122 so as to avoid narrowing the opening 122 in the second configuration.
In the embodiment being described, an edge of the first shaped sheet 134 nearest the third side 106 of the container 100 (the closed end) is curved away from the third side 106. The curve is relatively shallow (0.8 cm along the length of the container 100/away from the side 106 for 3.5 cm along its length in the embodiment being described), so allowing the flap 130 to extend along most of the length of the container 100. In the embodiment being described, the container 100 is arranged to be opened by cutting off the third side 106 -the skilled person will appreciate that the first shaped sheet 134 curving away from the side 106 may allow there to be less material/fewer layers to cut through, so facilitating opening of the container 100 In the embodiment being described, the edge of the internal flap 130 nearest the third side 106 continues the curve, C. The skilled person would appreciate that a straight line could be used instead of a curve in other embodiments. In the embodiment being described, the internal flaps 130 are angled/curved upwards towards the middle of the container 100 from the lower edge 106 thereof The skilled person will appreciate that the curvature may reduce the amount of material to be cut through when a machine or other cutting tool is used to cut off the bottom of the container 100, so reducing wear and load on the cutting tool.
The second shaped sheet 132a, 132b is connected to the respective internal flap 130a, 130b along a second line of weakness 131a, 13 lb. In the embodiment being described, the line of weakness 131a, 131b is a perforated line; in other embodiments folds, scores, or the likes may be used instead of or as well as perforation, in the embodiments being described, the first and second lines of weakness 131, 133 are parallel and define the lengths of the respective flaps 130. The second shaped sheet 132 extends from the opposite side of the internal flap 130 as compared to the first shaped sheet 134.
The second shaped sheet 132 is sized and shaped such that the second shaped sheet 132 lies between the flap 130 and the closest side 102/104 of the container. The second shaped sheet 132 is parallel to and in the same plane as the flap 130 in the first configuration. The second shaped sheet 132 is parallel to and in an adjacent plane to the first shaped sheet 134 in the first configuration. The second shaped sheet 132 is at an angle to the flap 130 (optionally an angle between 45 " and 90") in the second configuration. The second shaped sheet 132 is spaced from the first shaped sheet 134 in the second configuration.
In the embodiment being described, the edge of the second shaped sheet 132 furthest from the flap 130 is immediately adjacent, and optionally in contact with, the side 102, 104 of the container 100. When pressure is applied to move the container 100 from the first configuration into the second configuration, the first and second sides 102, 104 are pushed together (forming centre lines of the third 170 and fourth faces), so pushing the flap support structure and causing the flaps 130 to rotate about the first line of weakness 133a. in the second configuration, the third and fourth faces 130, 140 hold the flap support structure 132 in place, so holding the flap 130 in its second position. Figure 17 shows a view of the container 100 in a partly-assembled configuration; it can be seen that the third and fourth faces 170, 180 each make contact with the respective flap support structure 132a, 132b.
The shaped second sheet 132 of the flap support structure may slide along the first face 110 between the first and second configurations. The second shaped sheet 132/flap support structure may therefore be described as an actuating clement for the corresponding internal flap 130.
In the embodiment being described, the edge of the second shaped sheet 132 closest to the fourth side 108 has a protruding portion 135 (the protruding portion is substantially triangular in shape in the embodiment shown but may take an alternative shape in alternative embodiments) extending toward the fourth side 108. The protruding portion 135 extends closer to the fourth side 108 than the flap 130 does.
The protruding portion 135 extends beyond the slit 122, such that at least a tip of the protruding portion is beneath the portion 127a of the second face 120 between the slit 122 and the fourth side 108. The protruding portion 135 ends before the point at which the first and second faces 110, 120 are adhered together 127b. The protruding portion 135 can therefore slide beneath the portion 127a of the second face 120 between the slit 122 and the fourth side 108. The skilled person will appreciate that being beneath the portion 127a of the second face 120 may limit the motion of the second shaped sheet 132 at least substantially to the plane parallel to the second face 120. The end portion of the first face is adhered to the second face only along the edge 108 in the embodiment being described, so allowing the protruding portion 135 to slide beneath the portion 127a of the second face. The sliding therefore provides a limitation on flap movement.
The internal flaps 130 and support structure 132 have a width selected to contact the inside of sides 102, 104, so that when the container 100 is squeezed the flaps 130 are pushed into position, forming internal walls. The walls can be vertical in the second configuration (i.e. perpendicular to the first and second faces) in the embodiment being described. The skilled person will appreciate that the angle may depend upon the pressure exerted.
In the embodiment being described, friction on the flap support structure is such that the container 100 relaxes into an intermediate configuration after the applied pressure is released (i.e. with the central regions 117, 127 of the first and second faces 110, 120 closer together than in the second configuration, but with a space remaining therebetween). The internal flaps can therefore provide some resistance against the container returning from the second configuration to the first configuration. The skilled person will appreciate that the inward motion of the faces 110, 120 as the container 100 relaxes may exert a pressure on the item 10, so potentially maintaining the item 10 in place even if the container 100 is tipped upside-down before being sealed. The skilled person will appreciate that this relaxation may also reduce the space taken up by the container 100 when the item 10 is inside it -the container 100 of such embodiments may become as slim as it can be whilst retaining its protection and location of the item 10 inside. The size reduction may be advantageous in transportation.
In alternative embodiments, the container 100 may be maintained in the second configuration or return to the first configuration when the pressure is released. In embodiments in which the container 100 does not return to the first configuration when the pressure is released, applying a pressure between the first and second faces 110, 120, in some cases after pushing the internal flaps 130 away from an angle substantially perpendicular to the first and second faces 110, 120, may cause the container 100 to return to the first configuration, or to an intermediate configuration if there is an item 10 within the container 100. Movement between the configurations is reversible in the embodiments being described.
In the embodiment being described, the internal flaps 130 provide some resistance against the central region 117, 127 of each face 110, 120 bowing inwardly between the first and second sides 102, 104 when the pressure is applied to the first and second sides. The height of the flaps 130 may help to maintain the height of the container 100 in the second configuration.
In the embodiment being described, the internal flaps 130 are locked in the second configuration (the "popped up" form) and will not return to the first configuration until a sideways force is applied thereto -for example by inserting a finger or implement through the opening to push the flaps 130 from inside the container 100. The third and fourth faces 170, 180 are not locked in the popped-up position in the embodiment being described, however, and relax to the intermediate configuration, supported by the internal flaps 130. Similarly, the "jaw"-type widened opening is generally not locked in the second configuration and relaxes to the intermediate configuration, narrowing back to a slit 122.
In the embodiment being described, an absorbent material 140 is provided within the container 100, and more specifically in the channel 131 formed between the internal walls 130. In the embodiment being described, the absorbent material is provided in a strip oriented along the channel In alternative or additional embodiments, different shapes and/or locations may be used.
In the embodiment being described, the absorbent material 140 is positioned spaced away from the opening (by 8 mm in the embodiment being described, although the skilled person will appreciate that the spacing may vary); the skilled person will appreciate that this may reduce the risk of the item 10 catching on the absorbent material 140 when inserted into the container 100.
In the embodiment being described, the absorbent material 140 is adhered to the second face 120. In alternative embodiments, the absorbent material 140 may be adhered elsewhere on an internal surface of the container 100, for example to the first face 110.
In the embodiment being described, the absorbent material 140 is a cellulosic absorbent material. In additional or alternative embodiments, different absorbent materials may be used. In the embodiment being described, the absorbent material 140 is selected and sized to be able to absorb a volume of moisture equivalent to the item's maximum fluid content, such that the entirety of a leak may be absorbed. In alternative embodiments, the absorbent material 140 may only be capable of absorbing a portion of the maximum fluid content.
