[0081] Referring first to FIGS. 1 to 3, a first embodiment of a food package according to the disclosure is generally designated 1 and takes the form of a generally rectangular pouch. The package 1 is formed from first and second packaging films 10, 12 that are pressure- and/or heat-sealed together at their edges 18.

[0082] Food items, namely items of fruit 14, are held within the package 1, between the first film and the second film 12. The items of fruit 14 may be, for instance, slices of larger fruits such as apples or bananas, or whole pieces of smaller fruits such as strawberries. A fork 16 is also held between the first and second films 10, 12.

[0083] The first and second films 10, 12 are typically of food grade plastics material. However, in other examples of the disclosure, the first and second films 10, 12 may be of other suitable materials, for instance metal films or plastics/metal laminate or the like. In general, materials for use in forming the package of the disclosure will be those conventionally used for the vacuum-packing of foodstuffs, being flexible films that are sufficiently impermeable to air and which can be bonded together to form airtight enclosures.

[0084] In the process of manufacture of the package 1, the fork 16 and items of fruit 14 are placed on the first film 10, and overlaid by the second film 12. The first and second films 10, 12 are sealed together around the edge 18 of the films 10, 12, with the space between the first and second films being substantially completely evacuated, so that there is little or no air in the interior of the package 1. This has the effect of vacuum-packing the fork 16 and items of fruit 14 into a package, the films 10, 12 fitting closely around the fork 16 and the items of fruit 14, as can be seen in FIGS. 2 and 3.

[0085] The sides of the package 1 are provided, close to the upper (as viewed in FIG. 1) end of the package 1, with a pair of V-shaped notches 20, 21. The notches 20, 21 facilitate opening of the package 1 by a user grasping the upper part of the package 1 and tearing it off, along a line between the notches 20, 21. The opened package 1 is shown in FIG. 4. The process of opening the package 1 may be further facilitated by a line of weakness extending between the notches 20, 21 being formed in the package 1 during manufacture. Means by which such a line of weakness may be created are known and will be familiar to those skilled in the art.

[0086] The fork 16 is a suitable size for consuming the contents of the packet. Other utensils may be used instead of or in addition to a fork, for example a knife, spoon, or a pair of chopsticks. The fork 16 is of a rigid plastics material; however, in other embodiments the fork may be of another material, eg metal or wood. The fork 16 is positioned lengthways in the package, with the items of fruit 14 being adjacent to the fork. The fork 16 reinforces the package 1, protecting the fruit 14 from being damaged, for example when the package 1 falls to the collection area in a vending machine.

[0087] The shaft of the fork 16 is of generally rectangular section (see FIG. 2), with an internal bore 22 that extends from the upper (as viewed in FIG. 1) end of the fork 16 and terminates at an opening 24 close to the tines of the fork 16.

[0088] When the package 1 is torn open, as described above and as shown in FIG. 4, the tip of the shaft of the fork 16 protrudes slightly from the package 1. The user can then place the tip of the fork to their lips and blow gently through the fork 16 to separate the first and second films 10, 12. This then allows the fork 16 to be easily removed from the package 1 so that it can be used to remove the fruit items 14 from the package 1.

[0089] The first and second films 10, 12 have a dimpled, laser etched, or uneven texture on their juxtaposed surfaces. The uneven surfaces of the films 10, 12 reduce the area of contact between them and make the first and second films 10, 12 easier to separate when the package 1 is opened.

[0090] FIG. 5 shows a second embodiment of a food package according to the disclosure, generally designated 2. The package 2 is similar to the package 1 of the first embodiment, however the package 2 contains only a single item of fruit, namely one half of a peeled banana 25, along with a fork 26 that is identical to the fork 16 of the first embodiment. The package 2 also comprises a stiffener 27, which is a plastic rod. The stiffener 27 is located between the first and second films of the package, on an opposing side of the banana 25 to the fork 26.

[0091] The package is sealed around the edges 28, the space between the first and second films being substantially completely evacuated. The package is also sealed around the stiffener 27, in order that the stiffener 27 is separated from the fork 26 and banana 25. When the package 2 is torn open, in the same manner as the first embodiment 1, the stiffener 27 remains sealed in place.

[0092] Fresh bananas, especially when peeled, have a particularly short shelf-life and are particularly prone to physical damage. The package 2, from which air is substantially completely evacuated, and in which the fork 26 and the stiffener 27 provide protection to the banana 25 from damage caused by physical contact, mitigates these problems substantially. As a result, fresh bananas may be presented in this format in vending machines, or in other situations in which that would not hitherto have been feasible, for example in airline catering.

[0093] FIG. 6 shows a third embodiment of a food package according to the disclosure, generally designated 3. The package 3 is similar to the package 1 shown in FIG. 1. However package 3 also comprises a handle 32, which is made of the same material as the films of the package. The handle 32 is C-shaped and is attached to a side of the package 3. The handle 32 may be formed integrally with the package 3, for instance being formed by extensions of the films of the package that are bonded together. The handle 32 enables the package 3 to be held in the manner of a mug or cup, further facilitating the removal of food items from the package 3.

[0094] FIGS. 7 and 8 show a fourth embodiment of a food package according to the disclosure, generally designated 4. Like the third embodiment 3, the fourth embodiment of the food package 4 is broadly similar to the first embodiment 1. The package 4 differs from the first embodiment 1, however, in that it comprises a strap 34, which is attached at its ends to one face of the package 4. The strap 34 acts as a handle that may be gripped by a user in order to hold onto the package whilst eating the contents of the package.

[0095] Finally, FIGS. 9 and 10 illustrate a design modification that may be incorporated into any of the embodiments of a food package according to the disclosure described above (or into other forms of food package). The modification concerns the structure of the base of the package (ie the lower part of a package such as that shown in FIG. 1).

[0096] In the first embodiment 1 described above, and as illustrated in FIG. 1, the base of the package is formed simply by sealing together the two films 10, 12 that are used to form the package 1. In the modification illustrated in FIGS. 9 and 10, however, a flexible base component or gusset 51 is interposed between, and bonded to, the bottom edges of the films 52, 53 that are the major components of the package. The gusset 51 is resilient, typically being formed from the same or a different plastics material that is of greater thickness than the films 52, 53.

[0097] The gusset 51 is generally flat in form. However, when the package is filled, evacuated and sealed, the gusset 51 is bowed into the configuration shown in FIG. 9. In this configuration, the films 52, 53 are drawn into close engagement with the fork (indicated schematically as 54) and with the food items contained within the package (not shown).

[0098] As soon as the package is opened, ie when the vacuum within the package is released, the resilience of the gusset 51 causes it to relax to the configuration shown in FIG. 10. This draws air into the package, and causes the films 52, 53 to separate, releasing the fork 54 and food items contained within the package, which will then generally fall to the bottom of the package and rest upon the gusset 51.

[0099] The gusset 51, being of relatively thicker resilient material, confers a degree of rigidity on the base of the package, which may make it easier for the user to hold the opened package. The gusset 51 also provides a supportive surface against which the food items may be pressed by the fork 54, thereby facilitating piercing of those items by the fork 54. The thicker nature of the gusset 51 also reduces any risk of the gusset 51 itself being pierced by the fork 54, thereby reducing the risk of injury to the user of the package.

[0100] With this modification, other measures intended to facilitate opening of the package, such as the dimpled or uneven texture of the films or the provision of a hollow bore within the fork to enable air to be blown into the package by the user, may be unnecessary.

[0101] FIG. 11 shows a schematic cross-section of a food package 1100 in which the pouch 1102 has a base 1104 with a first corner 1106 and a top 1110 with a second corner 1108 diagonally opposite the first corner 1106. The pouch 1102 contains a utensil 1120, with a distal end 1122 and a proximal end 1124. The distal end 1122 may be configured to engage one or more of the plurality of food items 1130a-c. The proximal end 1124 may provide a handle for manipulation by a user. The pouch 1102 also contains a plurality of food items 1130a, 1130b. 1130c. The distal 1122 and proximal 1124 ends of the utensil 1120 are configured to engage with the first corner 1106 and the second corner 1108 respectively to reinforce the food package 1100. This reinforcement may provide advantageous structural strength and rigidity to the food package 1100, which may enable the food package 1100 to sustain impacts, such as being dropped within a vending machine, that may otherwise damage one or more of the plurality of food items 1130a, 1130b, 1130c.

[0102] In this example, the utensil 1120 is disposed inside the pouch 1102, such that engagement between the respective ends 1122, 1124 of the utensil 1120 and the first 1106 and second 1108 corners of the pouch 1102 occurs because the utensil 1120 is sized to fit snugly along a main diagonal of the pouch 1102. It will be appreciated that where the pouch 1102 has a substantially rectangular form, the appropriate length of utensil 1120 may be computed from a height and a width of the pouch 1102 using Pythagoras' theorem.

[0103] FIG. 12 shows a schematic cross-section of a food package 1200 with a gusset 1240 that makes up a base 1204 of the food package 1200. The food package 1200 contains a utensil 1220 and a plurality of food items 1230a, 1230b, 1230c. The gusset 1240 is formed to provide for shock absorption for the one or more of the plurality of food items 1230a-c when the base 1204 of the pouch 1202 is subject to an impact. Such an impact may occur when the food package 1200 is dropped within a vending machine. Any part of the gusset 1240 may elastically deform in response to the impact, to absorb the shock of the impact, and thereby ensure that a much smaller impulse is experienced by one or more of the food items 1230a-c than would otherwise occur.

[0104] The gusset 1240 may be slightly raised within the pouch 1320. The pouch 1320 may stand, or be supported, on a peripheral circumferential edge of the base of the pouch 1320. The cross-section shown in FIG. 12 shows that the gusset 1240 has a first end 1242 and a second end 1244, which may form part of the peripheral circumferential edge of the base of the pouch 1320 on which the weight of the food package 1300 may be supported when standing upright on a substantially level surface.

[0105] In this example, the food package 1200 also has a first gusset corner 1206 adjacent to the first end of the gusset 1242 and a second top corner 1208 spaced apart from the second end of the gusset 1244 and diagonally opposite the first gusset corner 1206. The first gusset corner 1206 provides a pocket for retaining the utensil 1220. Respective ends of the utensil 1220 are configured to engage with the first gusset corner 1206 and the second top corner 1208 to reinforce the food package 1200, in a manner similar to that already described in relation to FIG. 11. In this way, the elasticity of the gusset 1240, together with the resilience of the utensil 1220 may synergistically improve the shock absorbing capabilities of the food package 1200.

[0106] In some examples (not shown), a food package of the present disclosure may have a gusset configured to provide a containment barrier for containing a sharp or pointed utensil, such as a knife or a fork, within the pouch. The containment barrier may comprise thicker material than the rest of the pouch. This containment effect may be provided while the food package is in transit or storage, but may also provide an advantageous containment effect when the food package is in use by a user. For example, the gusset may be sufficiently resilient to enable a user to support the food package in one hand while spearing food items within the pouch with a sharp utensil without puncturing the gusset. Thereby, the user may avoid puncturing their hand as it supports the food package in use.

[0107] FIG. 13 shows a schematic cross-section of a food package 1300 including a pouch 1302. To improve the clarity of the disclosure, food items contained within the pouch 1302 are not shown. The pouch 1302 has a top portion 1310 connected to a body portion 1312 by a frangible section 1314. The frangible section 1314 may comprise a line of weakness with v shaped notches at opposite ends of the frangible section 1314 for ease of opening at both ends. A sealing strip 1320 is provided inside the pouch 1302, such that the sealing strip 1320 is positioned between the frangible section 1314 and the body portion 1312. The sealing strip 1320 consists of a reinforcing structure that can deflect tears away from the body portion 1312 when the pouch 1302 is opened by tearing the frangible section 1314. For example, if a user starts to tear the frangible section 1314 and a tear begins to propagate out of the frangible section 1314 towards the body portion 1312, then the sealing strip 1320 may deflect the tear back towards the frangible section 1314. In this way, the body portion 1312 of the pouch 1302 may be protected from unwanted damage when the food package 1300 is opened by a user. Thereby, the opened package may still be resealed to keep the remaining contents fresh once the user has consumed an initial portion of food items.

[0108] In some examples, the frangible section 1314 may further comprise a permanent seal, such as a weld or section of adhesive provided to permanently seal the pouch 1302 until the frangible section 1314 is removed. Between the permanent seal and the sealing strip 1320 there may be provided a line of weakness with V shaped tear notches at both ends of the line of weakness on opposing sides of the pouch 1302, configured to facilitate opening the food package 1300. In other examples (not shown) a permanent seal may instead, or additionally, be provided above the frangible section 1314, that is, one the opposite side of the frangible section 1314 compared to the sealing strip 1320.

[0109] The food package 1300 also comprises a utensil 1330 contained, in this example, within the pouch 1302. The opposite ends 1332, 1334 of the utensil 1330 are configured to engage with a diagonally opposite corners of the pouch 1302, in a manner similar to that disclosed above in relation to the food package of FIGS. 11 and 12. However, in this example, the proximal end 1334 of the utensil 1330 is engaged with a top-corner 1308 formed between and edge of the pouch 1302 and the sealing strip 1320. In this way, the utensil 1330 may provide the shock absorbing and rigidity promoting functionality described above, while still enabling the sealing strip 1320 to be sealed within the pouch 1302. Thereby, the pouch may comprise two or more seals, provided by the sealing strip 1320 and a permanent seal, either within or above the frangible section 1314, that may advantageously secure the contents of the pouch 1302 before a user opens the food package 1300.

[0110] It will be appreciated that, when the food package of FIG. 12 is provided with a sealing strip, similar to that of FIG. 13, a utensil may engage a top corner formed between the edge of the pouch and an end of the sealing strip, such that the utensil may be contained within a body portion of the pouch underneath the sealing strip.

[0111] FIG. 14 shows a schematic cross-section of a food package 1400, similar to that shown in FIG. 13, which has been opened by complete removal of a top portion (not shown). The food package 1400 has a pouch 1402 that incorporates a sealing strip 1420 that is exposed when the pouch 1402 is opened. The sealing strip 1420 is configured to enable the opened food package 1400 to be resealed after the food package 1400 has been opened. The sealing strip 1420 may itself be opened to enable the user to access remaining food items (not shown) contained within the pouch, and then resealed to keep unconsumed items, which are still within the pouch, in a fresh condition. The sealing strip 1420 may enable the pouch 1402 to be opened and resealed a plurality of times. In some examples, the sealing strip 1420 may comprise interlocking engagement members with complementary shapes that may be interlocked to provide a seal. In some examples, the sealing strip may comprise an adhesive strip or strips configured to provide a seal by adhering to respective sides of the juxtaposed surfaces of the pouch. By resealing the pouch 1402 after consuming an initial helping of food items, the remaining contents may advantageously be kept in better condition, for subsequent consumption, that would be the case if the pouch was not resealed.

[0112] FIG. 14 also shows an inserted-utensil 1430 that has been partially inserted into the pouch 1402 below the level of the sealing strip 1420. The inserted-utensil 1430 may be an example of a utensil provided as an integral part of the food package 1400 or may be any other suitable utensil. The sealing strip 1420 is configured such that the sealing strip 1420 is biased to grip the inserted-utensil 1430 in a static position. That is, the sealing strip 1420, in this example, naturally pulls the juxtaposed surfaces of the pouch together such that it can grip an inserted-utensil 1430 and hold it in an immobile position. This advantageously enables the user to let go of the inserted-utensil 1430 without it either dropping into the pouch 1402 entirely or falling out of the pouch 1402 entirely, and potentially falling to the ground. In this way, the sealing strip advantageously holds the inserted-utensil 1430 in a position where it is ready for use, while reducing the likelihood of any part of the inserted-utensil 1430 becoming soiled.

[0113] It will be appreciated that the utensil may be provided either inside the pouch of a food package of the present disclosure, or may be provided outside of the pouch of a food package of the present disclosure.

[0114] Where a utensil is provided outside of the pouch, it may be contained in a separate envelope or sachet to maintain the utensil is a clean and/or sterile condition until it is required for use. The utensil may be attached to the exterior of the pouch by any suitable means such as adhesive materials or welding, or alternatively where appropriate, an envelope containing the utensil may be attached to the exterior of the pouch by any such suitable means. In this way, the utensil may still provide improved structural strength and/or rigidity, and/or shock absorbing capabilities to the food package, as described above in relation to utensils provided inside of the pouch.

[0115] FIG. 15 shows a schematic cross-section of a medical package 1500 which includes a pouch 1502. The medical package 1500 may share any of the characteristics and/or functionality of the food packages described above, except that the medical package 1500 contains medical items 1530, 1532 instead of food items. In this example, the pouch 1502 contains a medical utensil 1520. The medical utensil 1520 may be pair of forceps or tongs, suitable for manipulating medical items or devices, or any other type of medical utensil without restriction. Medical items 1530, 1532 may include, for example, a medical dressing, a medical disinfectant wipe, a medical swab or any other type of medical supply, which may advantageously be manipulated with the medical utensil 1520 once the pouch 1502 has been opened.

[0116] As described above in relation to food packages, the medical package 1500 may be resealable after opening. The pouch 1502 may be depleted of oxygen and the medical utensil 1520 and medical items 1530, 1532 may be held in substantially fixed positions within the pouch 1502. In other examples, the medical utensil 1520 may instead be provided outside of the pouch 1502.

[0117] The medical package 1500 may be made from antibacterial materials, such as an antibacterial polymer. Use of a resealable, and optionally antibacterial, pouch 1502 may enable medical items to be stored in better condition, for future use, after the medical package 1500 has been opened than would otherwise be possible.

[0118] Generally, packages of the present disclosure may be provided in the form of a stand-up pouch that is manufactured from an anti-bacterial material. The inner surfaces of the pouch may be configured to be in direct contact with the contents of the pouch, in order to reduce or inhibit bacterial growth that may occur in food items and also to reduce or inhibit bacterial contamination for non-food items (such as platers or surgical gauze), when the packaging is opened.

[0119] For food packages the sealing strip may have at least two functions; the first would be to reseal the pouch after consumption of all or part of the contents; and the second would be to protect the contents from external contamination and to ensure that the anti-bacterial inner surfaces of the pouch remains in-contact with the surface of the food items. Re-sealing is of particular importance as the pouch may incorporate a utensil (such as a fork) to facilitate user access to the food contents of the pouch. The re-sealability of the pouch would also enable the partial or intermittent consumption of the contents of the pouch.

[0120] When the utensil enters the user's mouth it may become contaminated with bacteria from the mouth and therefore when re-introducing the utensil into the pouch it may increase the risk of bacterial contamination. However, the inner anti-bacterial surfaces of the pouch may significantly assist in reducing the potential risk of contamination to the food contents that may otherwise occur. Similar advantages may also be provided in relation to medical packages comprising medical items.
