The present disclosure relates to packaging for articles to facilitate safe shipping/storage of said article.
Articles that are generally planar, particularly artwork, require shipping from a first to a second location, which are typically a retailer location and a customer location respectively. The articles may also require storing for a significant period of time, e.g. an article is stored at the retailer location until it is sold. For said shipping/storage various packaging has been proposed.
Packaging arranged as a tube to receive a rolled article has been proposed. A drawback is that, although the tube can provide acceptable protection for the article, the act of rolling the article may introduce damage, e.g. prolonged curvature of the surface of the article can introduce compressive and tensile stresses which can permanently deform the article and/or damage a printed/painted surface.
Packaging arrange as a box has alternatively been proposed. The box is arranged to package the article without rolling. The damage that may be caused by rolling is therefore circumvented. A drawback is that the box needs to be specifically sized to fit the article, i.e. a range of article size cannot be accommodated in the box. Alternatively, an oversized box may be implemented that, to prevent damage from the article moving inside the box, has a filler material inside (e.g. bubble wrap or cardboard). A drawback is that the filler material is often single use and is discarded as waste.
Packaging arranged as a reinforced or hardback packaging slip has been proposed. A packaging slip comprises opposed faces, often made of cardboard, that are separated to receive an unrolled article therebetween. A drawback is that since the slip has a low second moment of area, particularly when compared to the tube or box, the slip provides significantly less protection. Moreover insertion into the slip may introduce damage either by friction or folding.
Therefore, despite the effort already invested in the development of said packaging further improvements are desirable.
The present disclosure provides packaging for an article. The packaging comprising a body portion to at least partially house the article, the body portion having an adaptive portion including a fluidically sealable cavity with particle material arranged therein, the particle material displaceable in the cavity to a corresponding position to correspond (e.g. in shape) to the article, with fluid removable from the cavity to hold the particle material in the corresponding position.
By implementing an adaptive portion, with displaceable particle material, the displaceable material can be arranged to surround the article to protect articles of various shapes, either as the article is being placed in or on the packaging and/or when fluid is removed from the cavity with the article in the packaging. The particle material can then be set in this position by removal of the fluid. The packaging may therefore be able to adapt to a range of article sizes.
An article packaged in the packaging may be referred to as being in a packaged position. As used herein term “least partially house the article” may include the article fully surrounded by the packaging or partially surrounded, e.g. including with an edge of the article exposed.
In embodiments, the cavity is arranged between an exterior wall and an interior wall, with the interior wall to face the article in the packaged position, such that the particle material is not in direct contact with the article.
As used herein the term “face” may refer to the interior wall arranged in direct contact with the article or with an intermediate member (e.g. a protective layer) interposed therebetween. It may more generally refer to a vector normal to the exposed face of the wall extending towards the packaged article.
As used herein the term “arranged between” in respect of the cavity position may refer to the cavity being formed by the exterior wall and the interior wall or an intermedial member, including an insert, interposed between one of both of said walls and the cavity.
In embodiments, the body portion includes a back portion and a front portion. The back portion and front portion may be movably connected. The body portion may have a closed configuration, in which the back portion and front portion are arranged about opposed faces of an article and an open configuration for receiving the article. By implementing the back and front portion to close around an article, the article may be conveniently packaged.
As used herein the term “closed configuration” may refer to a position where the front portion and the back portion are brought together, e.g. such that they are generally aligned to each other. In the closed configuration, on the front portion and/or back portion, the interiors walls may abut the article, including via in intermediate member (e.g. an insert) interposed between said portion(s) and the article.
As used herein the term “open configuration” may refer to a position where the front portion and the back portion are separated by sufficient an amount such that an article can be inserted between said portions, and where present a positioning system operated. In an open configuration the front and back portions may be out of alignment with each other, e.g. they are inclined.
[Positioning System]
In embodiments, the packaging comprises a positioning system that is arranged to position the article on the body portion in a positioned configuration in the open configuration. The positioning system may maintain the article in the positioned configuration as the packaging is transitioned between the open configuration and the closed configuration. By implementing a positioning system, the article can be positioned on the packaging in the open position, and then maintained in position as the packaging is moved to the closed position.
Implementing a positioning system may be particularly advantageous in combination with the adaptive portion, since if the adaptive portion is punctured (or otherwise) and the particle material moves from the corresponding position, an article is still held by the positing system is therefore prevented from moving in the packaging, which could otherwise cause damage, particularly if the article were to move to the edges of the packaging.
In embodiments, the positioning system is arranged to position the article on the interior wall in a positioned configuration, and may be arranged on the interior wall. By implementing the positioning system to position the article on the interior wall, the article may be correctly retained in the positioned configuration on said wall, including when the packaging is opened and closed.
In embodiments, the packaging is configured such that with the packaging in the open position, and not in the closed position, the positioning system is movable between an open position to receive the article and a closed position, in which the article is arranged in the positioned configuration. With such an arrangement the article may be prevented from moving from the positioned configuration when the packaging is in the closed position.
In embodiments, the positioning system is arranged on the interior wall and to directly engage (e.g. not through the interior or exterior wall) the article.
In embodiments, the positioning system is arranged to retain articles of varying dimensions in the positioned configuration. By arranging the positioning system to be suitable for engaging articles of varying size (e.g. by up to 40 cm in variation), a range of articles may be positioned by the positioning system.
In embodiments, the positioning system comprises extensions that extend from the interior wall and a connection system to retain the extensions in a closed position, in which the extensions engage and extend around an edge of the article. By implementing extensions that are fixed, e.g. by bonding or sewing, to the interior wall, they may provide a convenient positioning system. The connection system may be integrated with the extensions or separate therefrom.
In embodiments, the extensions comprise portions of flexible material, which are arranged to engage opposed sides of the article. The connection system and/or extensions may have a variable engagement position for engagement of articles of varying dimensions.
In embodiments, the extensions include the cavity. By implementing the extensions to include part of the cavity, improved protection may be provided.
In embodiments, the cavity is disposed on the front portion and the back portion. By arranging the cavity to extend continuously around the front and back portion, both sides and edges of the article may be protected by the adaptive portion.
[Valve Location Invention]
In embodiments, the packaging includes a valve carrying portion carrying a valve, the valve fluidically connected to the cavity of the body portion (e.g. via the valve carrying portion).
In embodiments, the valve carrying portion extends (e.g. it is arrangeable to extend) from (e.g. outwardly, including in a lateral and/or longitudinal direction) the body portion. By arranging the valve carrying portion to extend away from the body portion, it may be ensured that the valve is not pressed into the body portion as fluid is being pumped from the cavity. Pressing the valve into the body portion, e.g. when the valve is connected to a pump, could cause damage to a packaged article. By arranging the valve carrying portion to extend away from the body portion, it may be possible to implement a label caring portion on the valve carrying portion (e.g. on a rear face thereof). The label carrying portion may extend outward from a stack of the packaging and may therefore be convenient to read to identify the packaging. The valve carrying portion may be defined as a portion of the packaging that does not provide a function of housing the article.
In embodiments, the valve carrying portion extends (e.g. in an extended position) with the valve not to overlap the body portion. With the valve arranged not to overlap the body portion the valve may be pressed during removal (e.g. by a pump) of the fluid without damage to a packaged article.
In embodiments, the valve carrying portion is biased to the extended position. By biasing the valve carrying portion to the extended position (e.g. by material geometry and/or elasticity) it may be conveniently accessed. It may also be ensured that the valve is not pressed into the body portion when connected to a pump.
In embodiments, the valve carrying portion is arrangeable in a retracted position to overlap the body portion. The valve carrying portion may be moved to the retracted position so that it may be conveniently stowed.
In embodiments, the valve carrying portion is movable between the extended position and the retracted position. By implementing a movable valve carrying portion it can be conveniently moved between stowed and fluid extraction (extended) positions.
In embodiments, the packaging includes an securing system to secure the valve carrying portion in the retracted position.
In embodiments, the valve carrying portion extends from a peripheral edge of the body portion. By arranging the valve carrying portion to extend outwardly, i.e. away from the body portion, at an outer edge of the body portion, it can be ensured that the valve is not pressed into the article when the fluid is evacuated from the cavity.
In embodiments, the body portion and valve carrying portion are integrally formed. By forming the body portion and valve carrying portion from the same pieces of material, manufacturing may be convenient. It may also be ensured that the valve carrying portion is fluidically sealed with the body portion.
In embodiments, the valve carrying portion is arranged on the front portion or the back portion of the body. By arranging the valve carrying portion on the front portion it may be more convenient to access.
In embodiments, the positioning system and valve carrying portion are arranged such that with the packaging in the closed configuration and the positioning system positioning an article in the positioned configuration, the valve carrying portion does not overlap the positioned article.
By arranging the valve carrying portion and positioning system to position an article away from the valve, so that the valve does not overlap (extend over, when viewed in a plane defined by the longitudinal and lateral directions) a positioned article, said article may be less likely to be damaged by pressing of the valve into the article.
In embodiments, the valve carrying portion is at least partially (including fully) arranged in an extension portion of an exterior seam of the cavity to at least reduce proximity of the valve to a packaged article, e.g. an article in the positioned configuration. By arranging the valve in a pocket formed by the exterior seam, the valve may be hidden behind the exterior seam to reduce proximity to an article.
[Self-Sealing Valve]
In embodiments, the packaging includes a valve fluidically connected to the cavity of the body portion, wherein the valve is arranged as a planar member formed of a plurality of layers, with a displaceable layer carrying a displaceable member, the displaceable layer connected (e.g. directly or via an intermediate member) to an exterior wall of the packaging, the displaceable member displaceable between open and closed positions to open and close said valve. By implementing a valve that is formed of a plurality of layers the valve may be low-profile and may less likely to cause damage if pressed into a packaged article.
In embodiments, the valve is biased closed by the displaceable member biased to the closed position due to an elasticity of the displaceable layer. With such an arrangement a complex valve structure may be avoided.
[Front and Back Construction]
In embodiments, in the closed configuration the cavity is arranged to extend from a top edge to a bottom edged of the packaging on both front portion and back portion. By arranging the cavity to extend entirely across the packaging in a lateral direction, an article may be fully enclosed by the cavity and the usable size of the packaging may be optimised.
In embodiments, the front portion is connected to a bottom edge of the back portion and a second front portion is connected to a top edge of the back portion. The cavity may be disposed on the first portion and not the second front portion. By not arranging the cavity on the second front portion, protruding layers of the packaging may be minimised.
In embodiments, the front portion is arrangeable in the closed configuration to overlap the article, and the second front portion is arrangeable in the closed configuration to overlap the front portion.
By implementing the second front portion to overlap the front portion, the front portion may be secured in the closed configuration.
[Connection System]
In embodiments, a connection system to connect the front portion and back portion in the closed configuration extends in a lateral direction proximal (including at or in close proximity to) to an opposed left side and right side of the back portion and font portion. By implementing a connection system around the sides of the packaging the connection system may be arranged distal an article in the packaged position such that it does not damage the article. The connection system on the front portion and back portion may not extend between the left and right sides, e.g. in a longitudinal direction.
In embodiments, the connection system is implemented as hook-and-loop fasteners. By implementing a Velcro™ type fastening system the packaging may be releasably fixed in the closed position.
In embodiments, an exterior seam of the cavity extends in a lateral direction proximal to the left side and right side of the front and back portions. In embodiments, the connection system is arranged between (including a portion of the connection system or all of the connection system) said left said an right side and the exterior seam, wherein the connection system defines left side and right side extensions configured for grasping the packaging such that the user does not have to grasp the packaging proximal the packaged article. As used herein the term “grasping” may refer to holing by or as if by clasping with the fingers and/or between fingers and an opposed thumb. By arranging the connection system on flaps created by the exterior seam of the cavity, convenient extensions as handle portions are provided at each side of the packaging, which can be held without damaging the article. Moreover, the handle portions are located away from the cavity and particle material, which if alternatively located over each other could be susceptible to delamination or other damage. There may be two overlapping extensions formed on both left and right sides associated with the front and back portion respectively, or a single of one of said extension.
In embodiments, the extensions have a length in a longitudinal direction from the exterior seam of at least 3 or 5 cm, with a maximum of 10 or 15 cm. Such a size range is suitable for grasping.
In embodiments, the handle portions include grasping features. Grasping features (e.g. cut-outs or protrusions) may make the packaging easier to move.
In embodiments, a connection system to connect the front portion and back portion in the closed configuration extends in a lateral direction proximal (including at or in close proximity to) to the exterior seam.
In embodiments, the exterior seam is arranged to fluidically connect (e.g. it comprises an aperture) the cavity to the valve carrying portion. By not arranging the seam not to substantially extend over the valve carrying portion (or an interface between the valve carrying portion and the body portion), the cavity may be fluidically connected to the valve carrying portion. In embodiments, the exterior seam bounds the cavity except for at the valve carrying portion.
In embodiments the connection system extends over an interface between the valve carrying portion and the body portion. By arranging the connection system to extend over the valve carrying portion integrity of the connection system may be maintained in spite of the valve carrying portion.
[Material Ranges]
In embodiments, a weight of the interior wall is less than a weight of the exterior wall. In embodiments, a weight difference between the exterior wall and interior wall is at 200 g/m2 to 700 g/m2 or 400 g/m2 to 600 g/m2.
In embodiments, the exterior wall has a weight of 500 g/m2 to 1200 g/m2 or 600 g/m2 to 800 g/m2.
In embodiments, the interior wall has a weight of 100 g/m2 to 250 g/m2 or 160 g/m2 to 200 g/m2.
By implementing an outer material and an inner material of these thickness ranges it has been found that the outer material may provide suitable protection for the article, whilst the interior wall may be sufficiently flexible to mould to the shape of the article, however it is not too flexible such that it forms a substantial amount of wrinkles that could damage the article if pressed into the article. Moreover, the outer layer may be sufficiently rigid to prevent substantial expansion of the cavity by fluid ingress and cause the particle material to become unevenly distributed.
As user herein the term “weight” when refereeing to an interior wall or exterior wall may refer to said wall on its own, or said wall including a directly adjoining wall on an insert.
In embodiments, the exterior wall and the interior wall of the cavity is formed of a plastic based material.
In embodiments, the plastic based material of the interior wall comprises a weldable plastic material, e.g. thermoplastic polyurethane. By implementing the interior wall as including a weldable plastic material, such as thermoplastic polyurethane, the material is weldable to enable the convenient formation of construction seams. Moreover, correct performance may be provided with respect to anti-wrinkling and material elasticity to enable the interior wall to adapt in shape to the article.
In embodiments, the plastic based material of the interior wall comprises a woven fabric, e.g. a woven polyester fabric. By implementing a fabric layer, the interior wall may have suitable abrasion resistance, e.g. so that the weldable plastic material is less likely to be punctured. The woven fabric layer may be arranged to adjoin the weldable plastic material, which is arranged as an interior layer (e.g. a layer that forms a wall of the cavity).
In embodiments, the plastic based material of the exterior wall comprises a woven fabric layer, e.g. a woven polyester fabric. By implementing a fabric layer, the packaging may have suitable rigidity (e.g. to avoid wrinkles) and abrasion resistance.
In embodiments, the exterior wall has a weldable plastic interior layer, e.g. thermoplastic polyurethane. By implementing a weldable plastic interior layer (e.g. a layer that forms a wall of the cavity) the material may be weldable to enable the convenient formation of construction seams.
By implementing the cavity with an interior layer of the exterior wall and an interior layer of the interior wall both formed of thermoplastic polyurethane, an electrostatic force may be generated to prevent over expansion of the cavity when the valve is in an open position. In this way it may be ensure that the particle material remains evenly distributed in the cavity (since over expansion can cause uneven distribution and aggregation of the particles) so that an article is adequately covered and therefore protected by the particle material.
In embodiments, the plastic based material of the exterior wall comprises a weldable plastic exterior layer, e.g. thermoplastic polyurethane (e.g. a layer to face away from an article in the packaged position). By implementing a thermoplastic polyurethane exterior layer to adjoin the woven fabric layer, suitable water, UV and chemical protection may be provided, it may also provide a weldable exterior to connect other components to.
In embodiments, the particle material has a major length (e.g. a diameter) of 0.1-6 mm or 0.25-3 mm or 0.5-1 mm. By implementing particle material of this diameter range, it has been found that the cavity may suitable mould the article, without the particle material unevenly aggregating if the size is too small, and without insufficient resolution or damage to the article if the size is too large. In particular, it has been found that as the particle material major length is increased above 3 mm the particle material does not provide sufficient resolution or may damage an article.
In embodiments, the particle material comprises a closed cell expanded plastics based material, e.g. expanded polystyrene. A closed cell expanded material may be light weight, and may have good shock absorption qualities to protect the article. The closed cell material may prevent fluid from moving though the particle material. In embodiments, the particle material has a density of 12 to 20 kg/m3.
[Interior Seam]
In embodiments, a first layer and a second layer (which may be the exterior wall and interior wall, or walls of an insert arranged between the exterior wall and the interior wall) form the cavity and are connected at one or more interior seam that is arranged: distal the edges of the cavity, and; to restrict movement of the particle material in the cavity. By arranging an interior seam within the cavity (e.g. as opposed to an exterior seam that bounds the cavity), the movement of particle material in the cavity can be restricted, such that an even distribution of particle material may be maintained around the article.
In embodiments, the or each interior seam is elongate and is arranged with a major portion to extend along an axis parallel to a longitudinal direction of the packaging. Such an arrangement of the interior seam has been found to reduce wrinkling of the interior wall, which is less likely to cause damage to a packaged article.
In embodiments, the interior seams are arranged to define longitudinally extending rows, that are bounded by laterally extending columns, the columns arranged at laterally extending edges of the cavity. Such an arrangement of rows and columns may provide improved protection for an article. In embodiments, the interior seams include laterally extending minor portions. The minor portions may help to define said rows and columns.
In embodiments, the interior and/or exterior seam is formed by welding or adhesively connecting interior surfaces of the cavity together. By forming the seams by welding they may be conveniently formed from an exterior of the cavity.
[Interior Sock]
In embodiments, the particle material is arranged in an insert, the insert formed of a first layer and a second layer, the insert arranged a cavity formed by an exterior wall and interior wall. By implementing an insert to directly carry the particle material (rather than the exterior wall and the interior wall), the particle material may be conveniently inserted into the cavity defined by the exterior wall and interior wall. Moreover, the insert or the exterior wall and interior wall formation may be replaced should either become damaged.
In embodiments, the interior seams are arranged on the insert. In embodiments, the insert comprises an exterior seam. In embodiments, the insert is arranged within an exterior seam of the exterior wall and interior wall. The insert may be fluidical connected to the cavity of the exterior wall and interior wall. The cavity of the exterior wall and interior wall may be fluidical connected to the valve.
In embodiments, the insert has reinforcement positions for connection to the interior wall and the exterior wall. The reinforcement positions may provide a connection point (e.g. by welding or adhesive) for connection of the insert to said layers which is less likely to tear. Moreover, the reinforcement positions may enable the insert to be reattached to a different exterior wall and interior wall, e.g. if it is replaced.
[Protective Layer]
In embodiments, the packaging comprises a removable interior protective layer, which is arranged (e.g. it has sufficient dimension) to be interposed between the interior wall and the article in the packaged position. By implementing an interior protective layer to extend around the article, specific protection/reactivity can be tailored to the article, particularly as articles may be stored in the packaging for extended periods of time. For example, some articles may be damaged by a thermoplastic polyurethane interior layer.
In embodiments, wherein the interior protective layer is located on the interior wall by the positioning system. By locating the interior protecting layer on the interior wall it may be ensured to be in the correct position with respect to a positioned article.
In embodiments, the protective layer has a potential of hydrogen (pH) of 6 to 7. By implementing the protective layer with a relatively neutral pH, damage to the article may be minimised. In embodiments, the protective layer has a weight of 30 to 50 g/m2. By selecting the protective layer to have a weight within these ranges the article may be well-protected. In embodiments, the protective layer is based on fabric of high-density polyethylene fibres, e.g. it may comprise Tyvek™.
[Signal of Vacuumed State]
In embodiments, the packaging comprises an indication system to indicate when a threshold amount of fluid has been removed from the cavity. By implementing such a system a user is notified when sufficient fluid has been removed, which may prevent damage to the packaging caused by excessive fluid removal.
In embodiments, the indication system comprises a mechanical formation that increases in visibility as said fluid is removed. A mechanical formation based system, e.g. in which an exterior wall is drawn over a formation comprising a message with reducing fluid pressure, may provide a cost effective system.
In embodiments, the indication system comprises electrical circuitry with a sensor to determine fluid removal crossing a threshold and provide a notification to a user. An electrical circuitry based system may be particularly accurate.
In embodiments, the indication system comprises mechanical noise creation system, that is actuated to create an audible noise as fluid removal crosses a threshold. A mechanical noise creation system, e.g. an arrangement that creates a click based on pressure, may be cost effective.
[Air Channels]
In embodiments, the cavity includes a flow regulation system, which is arranged to maintain a network of flow channels within the cavity independent of an arrangement of the particle material. In embodiments, the flow regulation system comprises a member implementing an arrangement of conduits and/or undulations or is a meshed structure in the cavity to provide said flow channels.
By implementing a flow regulation system, it may be ensured that fluid is uniformly evacuated from the cavity, particularly as interior wall sections of the cavity, that may become void of particle material due to aggravation of particle material elsewhere, may come together under the reduced pressure to create a blockage.
In embodiments, the member is formed on an interior surface of the cavity or a separate element arranged within the cavity.
In embodiments, a diameter of the undulations or cavity is selected to be less than that of the particles, e.g. it may be 2-3 mm or 0.5-3 mm or less than 1, 2 or 3 mm. In embodiments, the flow regulation system overlaps the entire, including a substantial portion of the cavity. In embodiments, the flow regulation system is arranged to overlap the valve carrying portion. In embodiments, at least a portion of the flow regulation system extends across an entire (including substantially entire) lateral and/or longitudinal dimension of the cavity.

[General Arrangement]
Referring to
The body portion 6 includes an adaptive portion 8. The adaptive portion 8 includes a fluidically sealed cavity 10 which is bounded by the exterior seam 12. The adaptive portion 8 includes particle material 14 (illustrated in
A shape of the adaptive portion 10 can adapt to correspond to the article when pressed against the article. In particular, the particle material 14 is free to move in the cavity 10 and can, upon the cavity being pressed against the article, redistribute itself around the article to displace from a non-corresponding position to a corresponding position, in which its arrangement corresponds to the shape article 4. The cavity 10 can be evacuated with fluid (not illustrated) so that the particle material 14 is held in the corresponding position.
The exterior seam 12 of the cavity 10 joins an exterior wall 16 and an interior wall 18. Referring to
The packaging 2 is aligned in an in-plane direction, which is defined by a longitudinal direction 100 and a lateral direction 102, which are both orthogonal to a depth direction 104. The packaging 2 is formed from a single sheet of joined interior wall 16 and exterior wall 18, which is arranged in to a back portion 28 and a front portion 30.
In variant embodiments, which are not illustrated, the packaging is formed of separate sheets rather than a single sheet.
The back portion 28 and front portion 30 are movably connected at a bottom edge 32 of the packaging 2, which is formed by a fold in the sheet of interior wall 16 and exterior wall 18.
The back portion 28 and a front portion 30 both extend in the lateral direction 102 from the bottom edge 32 to a top edge 34 of the packaging 2 (the top edge 34 is formed at a fold interconnecting the back portion 28 and a second front portion as will be discussed). The back portion 28 and front portion 30 both extend in the longitudinal direction 100 between a first side edge 36 of the packaging 2 and a second side edge 38 of the packaging 2.
The back portion 28 and front portion 30 are movable from the open configuration in which an article can be received (shown in

[Interior Sock and Shaped Seam]
Referring to
The interior seams 46 (as discussed for the preceding embodiments) are arranged on the insert 90 rather than to join the exterior wall 16 and the exterior wall 18. The insert 90 comprises an exterior seam 96 to define a cavity 98 of the insert 90. The cavity 10 between the exterior wall 16 and the exterior wall 18 is defined by the exterior seam 12 (as discussed for the preceding embodiments). An aperture 110 in the insert 90 fluidical connects the cavity 98 of the insert 90 and the cavity 10, which is in turn connected to the valve as discussed for the preceding embodiments. Hence fluid is evacuated from both the cavity 10 and the insert 90 via the valve.
In variant embodiments, which are not illustrated: the interior seams are omitted, and; the interior seams may be formed to connect the exterior wall, the interior wall and the walls of the insert.
Referring to
In variant embodiments, which are not illustrated: there are other numbers of reinforcement portions, and; the reinforcement portions are alternatively located, e.g. at the corners.
Referring to
The interior seams 46 are arranged to define longitudinally extending rows 120, that are bounded by laterally extending columns 122. The rows 120 and columns 122 are characterised by the absence of an interior seam. The columns 122 are arranged at laterally extending edges of the cavity 98. In particular, the minor portions 116 define the columns 122, and the major portions 114 define the rows. The minor portions 118 define a separation distance between the rows.
[Self-Sealing Valve]
Referring to
A displaceable layer 130 is connected around its periphery to the support layer 132, to define an inner displaceable member 134. Apertures 136 in the displaceable member 134, which are implemented as arc-shaped flaps by means of slits, are for fluid transmission through the displaceable layer 130. The support layer 132 provides a comparatively rigid support for the displaceable layer 130 and includes an aperture 138 for fluid transmission therethrough. The aperture 138 of the support layer 132 is arranged not to overlap the apertures 136 in the displaceable member 134. In this way, fluid is only transmittable through said layers when the displaceable member 134 is displaced from the support layer 132 as shown in
[Signal of Vacuumed State]
The packaging 2 of any preceding embodiment, or another embodiment disclosed herein may implement an indication system (not illustrated). The indication system indicates to a user when a threshold amount of fluid has been removed from the cavity 10. The indication system may indicate to a user:
Condition 1) may for example be achieve during evacuation pumping to set the particle material in the corresponding position. Condition 2) may for example be achieved by a undesirable transition from condition 1) if the packaging is punctured or otherwise damaged.
In a first example the indication system comprises a mechanical formation that increases in visibility as the packaging transitions from condition 1) to condition 2). The mechanical formation may not be visible for condition 1) but may be visible for condition 2). As an example of such a system, a comparatively rigid indication member is located within the cavity 10. As fluid is evacuated from the cavity, the exterior wall 16 is drawn over the indication member, such that it becomes visible from an exterior of the packaging. The indication member may be shaped to provide a message e.g. “packaged” or “evacuated” or other suitable shape.
In a second example, the indication system comprises electrical circuitry with a sensor to determine fluid removal crossing a threshold and provide a notification to a user. The sensor may for example be a pressure sensor. The electrical circuitry may implement an indication system to provide said notification, e.g. via visual, haptic or audible feedback. The electrical circuitry may determine crossing of a threshold via a comparator or other suitable implementation.
In a third example, the indication system comprises mechanical noise creation system, that is actuated to create an audible noise as fluid removal crosses a threshold. As an example the mechanical noise creation system is implemented as a geometric construction that is arranged to snap between first and second configurations. The geometric construction may be located in the cavity such that it is actuated from a first position to a second position as the packaging is transitioned from condition 1) to 2), e.g. as the interior surface of the cavity presses on the geometric construction due to increasing reduction of fluid in the cavity.
[Air Channels]
Referring to
The flow regulation system 140 is implemented as a channel forming member 144 that directly adjoins the interior surface 26 of the interior wall 18 of the cavity 10. Undulations in the channel member 144 form closed channels between the channel forming member 144 and the interior wall 18 and open channels on the other side of the channel forming member 144.
The channels have a diameter that is selected to be less than that of the particle material, for example the width between adjacent walls of the channels may be 1-3 mm. In this way the particle material is prevented from blocking the channels 142.
The figures illustratively show the channel forming member 144 overlapping the valve carrying portion 50, however it may also overlap parts of or the entire remainder of the cavity 10. The channel forming member 144 is formed on the interior surface that includes the valve carrying portion so that the channels can fluidically link directly with the valve.
In variant embodiments, which are not illustrated: the channel forming member is formed integrally with the interior surface, e.g. by creating undulations is said surface via welding or addition of adhesive; in embodiments comprising the insert 90, the channel forming member is formed on an interior wall of the insert 90, and; the channel forming member may be formed on the other side of the cavity, e.g. on both sides or one side thereof.
Referring to
In variant embodiments, which are not illustrated: other channel creating members may be implemented, e.g. any fluidical communicative material that prevents the particle material blocking its passageways.
[Method of Forming Packaging]
A method of forming the packaging 2 may comprise the following steps:
Step 1: cut sheets of the exterior wall 16 and interior wall 18 to the peripheral shape illustrated in
Step 2: insert the valve 52 in to a valve aperture in the valve carrying portion 50.
Step 3: adhesively fix the connection system 30 to the interior wall 18.
Step 4: form the exterior seam 12, interior seam 46 and valve carrying portion seam 56 by high frequency welding.
Step 5: insert the particle material 14 into the cavity 10 via the valve 52, and close the valve 52 to prevent further transmission of the particle material in or out of the cavity 10.
Step 6: connect the protective layer 58 and positioning system 62 to the interior wall 18.
In variant embodiments: where appropriate the steps of method may be executed in a different order, e.g. step 4 before step 2 or 3 etc.; steps may be omitted, e.g. in embodiments that do not comprises a protective layer and/or positioning system step 6 can be omitted.
In embodiments that comprise an insert 90: the insert 90 can be formed to include the exterior seam 96 of the insert and the interior seam 46 of the insert; the insert 90 may then be inserted between the exterior wall 16 and interior wall 18 and connected at the reinforcement positions 112 to said walls; the exterior seams 12 may then be formed to connect the exterior wall 16 and interior wall 18 around the insert 90; the insert 90 may then be filled with the particle material 14, e.g. through an aperture of the valve carrying portion 52 before connection of the valve 52, and; alternatively the particle material 14 may be filled into the insert 90 before the insert 90 is inserted between the exterior wall 16 and interior wall 18.
[Method of Packaging an Article]
A method of packaging and article 4 in the packaging 2 may comprise the following steps:
Step 1: the valve 52 is set to the open position and it is ensured that there is enough fluid in the cavity 10 for mobility of the particle material 14.
Step 2: referring to
Step 3: referring to
Step 4: referring to
Step 5: referring to
As the packaging 2 is closed the interior wall 18 and particle material 14 are selected so that the cavity 10 is moulds to the shape of the article 4 (i.e. into the corresponding position) without the need for manually pressing it into the corresponding position.
Step 6: a pump (not illustrated) is attached to the valve 52, and with the valve 52 not overlapping the article 4 so as not to press the valve 52 into the article 4, fluid is removed from the cavity 10 to set the particle material 14 in the corresponding position around the article 4. The valve 52 is then moved to the closed position.
Step 7: the packaging 2 is then handled at the extension portions 44 distal the article 4.
In variant embodiments: where appropriate the steps of method may be executed in a different order, e.g. step 2 before step 1 etc.; steps may be omitted, e.g. in embodiments that do not comprises a protective layer and/or positioning system steps 2 and/or 3 can be omitted; in embodiments that do not comprise a second front portion step 5 can be omitted etc.

In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim. The word ‘comprising’ does not exclude the presence of other elements or steps then those listed in a claim. Furthermore, the terms “a” or “an,” as used herein, are defined as one or more than one. Also, the use of introductory phrases such as “at least one” and “one or more” in the claims should not be construed to imply that the introduction of another claim element by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim element to inventions containing only one such element, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an.” The same holds true for the use of definite articles. Unless stated otherwise, terms such as “first” and “second” are used to arbitrarily distinguish between the elements such terms describe. Thus, these terms are not necessarily intended to indicate temporal or other prioritization of such elements. The mere fact that certain measures are recited in mutually different claims does not indicate that a combination of these measures cannot be used to advantage.
Unless otherwise explicitly stated as incompatible, or the physics or otherwise of the embodiments, example or claims prevent such a combination, the features of the foregoing embodiments and examples, and of the following claims may be integrated together in any suitable arrangement, especially ones where there is a beneficial effect in doing so. This is not limited to only any specified benefit, and instead may arise from an “ex post facto” benefit. This is to say that the combination of features is not limited by the described forms, particularly the form (e.g. numbering) of the example(s), embodiment(s), or dependency of the claim(s). Moreover, this also applies to the phrase “in one embodiment”, “according to an embodiment” and the like, which are merely a stylistic form of wording and are not to be construed as limiting the following features to a separate embodiment to all other instances of the same or similar wording. This is to say, a reference to ‘an’, ‘one’ or ‘some’ embodiment(s) may be a reference to any one or more, and/or all embodiments, or combination(s) thereof, disclosed. Also, similarly, the reference to “the” embodiment may not be limited to the immediately preceding embodiment.
