Title: Spill resistant feeding device

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of PCT Application No. PCT/GB2020/052534 filed on Oct. 9, 2020, entitled Spill Resistant Feeding Device, which claims the benefit to GB 1914686.0, filed on Oct. 10, 2019 and GB 2006167.7 filed on Apr. 27, 2020, all of which are incorporated herein by reference in their entireties. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates to an item of cutlery that can be used for assisted feeding of a child, such as a toddler, or an individual having limited dexterity. 
     BACKGROUND TO THE INVENTION 
     For individuals with limited dexterity or difficulty with fine motor skills, eating semi liquid food (e.g. purees) with a conventional spoon can be challenging as the food easily falls from the spoon before it reaches the mouth. For example, infants in the early stage of weaning will want to grab the loaded spoon but are likely to wave it around, causing food to fly off in all directions and limiting the food reaching the mouth. As a result, carers tend to prevent the child from grabbing the spoon. This slows down the child&#39;s development of independent self-feeding skills. Even when the carer is holding the spoon, the child often knocks it and food falls off. Similarly, for many elderly people, or people with limited dexterity, spoon feeding can be frustrating and messy, necessitating intervention from the carer, which can be damaging to the individual&#39;s sense of independence and self-respect. 
     Current solutions include using food pouches to feed, for example, young children. These food pouches are provided with a short straw mouthpiece, through which the semi-liquid food is sucked out of the pouch. The pouch can be squeezed to help the child&#39;s suckling efforts, allowing for a feeding method that has very little mess. However, such food pouches do not solve the issue of developing the child&#39;s dexterity in addition to normal self-feeding spoon skills. Furthermore, the food is delivered to the back of the child&#39;s mouth, thus skipping the crucial steps of the child opening its mouth to accept the spoon into the oral cavity, closing the lips to draw the bolus of food from the spoon and transmitting the bolus form the front to the back of the mouth, further inhibiting the child&#39;s development of self-feeding skills. 
     Another solution involves straw spoons, wherein a straw has an open spoon element as a result of a longitudinal cut. However, when waved around, food loaded on to the spoon element will readily spill. Therefore, there remains an issue with the mess caused by the lack of appropriate feeding instruments. 
     It is therefore desirable to provide a solution which overcomes the disadvantages of the current feeding implements. 
     SUMMARY OF THE INVENTION 
     In accordance with the present invention, there is provided a spill resistant item of cutlery, the spill resistant item of cutlery comprising: a longitudinally extending elongate member having; a tubular retaining portion proximate a first end thereof; and a gripping portion proximate a second end opposing the first end. The tubular retaining portion comprises an interior retaining surface defining a retaining portion cavity. The tubular retaining portion further comprises a food inlet in fluid communication with the retaining portion cavity. 
     The spill resistant item of cutlery will be further understood as being any implement suitable for feeding. 
     The tubular retaining portion of the present invention preferably defines the retaining portion cavity such that the retaining portion cavity is tubular in shape. The skilled addressee will appreciate that the tubular description describes the present invention only. In additional embodiments, the tubular retaining portion comprises a volume having a cross sectional shape that is any of square, rectangular, ovular, circular or any shape that is appropriate for the functionality of the present invention. It is preferable that the tubular retaining portion cavity is of adequate volume so as to fit a food item in. If the tubular retaining portion were too small, then the food items would not be able to enter the retaining portion cavity. On the other hand, if the tubular retaining portion were too large, then food items would easily exit the retaining portion cavity. 
     In some embodiments, a radius of the cross-sectional shape of the tubular retaining portion varies along a longitudinal axis. Preferably, the radius increases along a first portion of the longitudinal axis and decreases along a second portion of the longitudinal axis such that the tubular retaining portion is substantially tear-drop or balloon shaped. Advantageously, the tubular retaining portion comprises a defined area on which a user may apply lip pressure. 
     In some embodiments, the tubular retaining portion comprises an indent. Preferably, the indent is located at an upper portion of the tubular retaining portion. Further preferably, the indent extends longitudinally along the tubular retaining portion. 
     In preferable embodiments, the tubular retaining portion comprises a tubular retaining portion material that allows for adequate compression such that food items are able to exit the retaining portion cavity when the tubular retaining portion is compressed. Preferably, the tubular retaining portion material is a flexible material. More preferably, the tubular retaining portion material is a flexible material that will return to its original shape after compression. Still more preferably, the tubular retaining portion material comprises a resiliently deformable material. In some embodiments, the tubular retaining portion material comprises silicone. Further embodiments will be appreciated by the skilled addressee wherein the tubular retaining portion material comprises any flexible material that allows for the compression of the tubular retaining portion. Advantageously, such an arrangement allows for greater ease of extracting food items as, in addition to suction, the tubular retaining portion can be squeezed (compressed) in order for food items to leave the retaining portion cavity. 
     In preferable embodiments, the interior retaining surface comprises a plurality of elevations. The plurality of elevations will be understood by the skilled addressee to be any suitably shaped elevation extending from the interior retaining surface into the retaining portion cavity. Preferably, the plurality of elevations is arranged to maximise surface adhesion between a food item present in the tubular retaining portion and the interior retaining surface. Additional embodiments may be envisaged wherein the tubular retaining portion comprises a pleat. A requirement for greater surface adhesion will require a greater surface area of the interior retaining surface, the surface area being proportional to the surface area of the plurality of elevations. It is preferable for the surface adhesion to be of sufficient magnitude such that the food items present in the tubular retaining portion are biased towards remaining within the tubular retaining portion. It is also preferable that the surface adhesion is not too great as to inhibit any attempt to remove the food item from the tubular retaining portion via, for example, suction. 
     In preferable embodiments, the plurality of elevations or protrusions comprises a plurality of longitudinal protrusions or ribs. In preferable embodiments the plurality of longitudinal protrusions will be understood to extend along the interior retaining surface longitudinally. In other embodiments, the plurality of protrusions comprises a plurality of protrusions extending in any direction along the interior retaining surface. 
     In some embodiments, one or more of the plurality of longitudinal protrusions comprise a height substantially greater than the other longitudinal protrusions. 
     Preferably, the food inlet is proximate an anterior end of the tubular retaining portion. In preferable embodiments, the anterior end opposes an anterior end longitudinally. Preferably, the food inlet is arranged such that fluids and/or semi-fluids are able to enter or exit the retaining portion cavity via the food inlet. In preferable embodiments, the food inlet forms part of the tubular retaining portion and maximises fluid communication between the tubular retaining portion cavity and an area beyond the food inlet. The physical shape of the food inlet may preferably match the cross section of the retaining portion cavity which, in preferable embodiments, is ovular. However, other embodiments exist wherein the food inlet has a circular, square, rectangular or any other shape that allows for food items to enter the tubular retaining portion. Preferably, the food inlet is arranged to minimise protrusions from the cavity wall proximate the food inlet. Advantageously, such an arrangement reduces the build-up of food items that may occur if a lip protruded from the tubular retaining portion surface. 
     In some embodiments, the food inlet may comprise a smaller radius than the cross section of the retaining portion cavity. 
     In preferable embodiments, the food inlet may be planar and may be chosen to extend at an angle longitudinally, the angle being, for example, 30 degrees. As a result, the food inlet may have a varying offset along an axis perpendicular to the longitudinal axis. Advantageously, such a shape may assist in transmitting the food items into the tubular retaining portion. 
     Preferably, the spill resistant item of cutlery further comprises an air vent. In preferable embodiments, the air vent or hole is arranged to allow air to exit the retaining portion cavity as food is entering. Advantageously, the air vent reduces the potential build-up of pressure that would otherwise oppose food items entering the retaining portion cavity. In further preferred embodiments, the air vent is arranged in fluid communication with the tubular retaining portion cavity. Advantageously, such an embodiment allows for the tubular retaining portion cavity to be easily cleaned as cleaning fluids are able to enter the retaining portion cavity via the food inlet and exit via the air vent or vice versa. 
     In some embodiments, the air vent may comprise a valve configured to alternate the air vent between an open configuration and a closed configuration. 
     Preferably, the air vent is proximate the posterior end of the tubular retaining portion such that the air vent opposes the food inlet. The air vent can be located at other locations along the gripping portion or handle of the feeding device or spoon. 
     In some embodiments, the shape of the air vent is ovular. In further embodiments, the shape of the air vent is circular, square, rectangular or any other shape that suitably allows for the air vent&#39;s function. 
     In some embodiments, the air vent extends in an angled orientation. That is, the air vent extends at an angle, relative to the longitudinal axis, from the tubular retaining portion to an exterior. Preferably, the angle is between 15° and 75°. Preferably, the angle of air vent is greater than the angle of the food inlet. Consequently, food items may be less likely to stick to, and block the air vent. Alternatively, the air vent may extend from the anterior end of the tubular retaining portion to the posterior end of the tubular retaining portion such. 
     In some embodiments, the spill resistant item of cutlery further comprises a cuff proximate the air vent. Preferably, the cuff comprises an indent configured to allow air flow between the air vent and an exterior. Preferably, the cuff comprises a depth configured, in use, to allow air flow between the air vent and the exterior. Advantageously, the cuff may prevent a build-up of negative pressure when a user applies suction to the spill resistant item of cutlery. Further advantageously, the cuff may provide an increased robustness to the spill resistant item of cutlery. Alternatively, the spill resistant item of cutlery may comprise a flange configured to envelop a portion of the outer surface of the spill resistant item of cutlery. 
     In further embodiments, the tubular retaining portion comprises an upper portion and a lower portion. Preferably, the upper portion is separated from the lower portion by a pair of opposing longitudinally extending indents. Preferably, the indents extend from the anterior end of the tubular retaining portion to the posterior end of the tubular retaining portion. Additional embodiments exist wherein the indents partially extend from the anterior end to the posterior end. Additional embodiments exist wherein there are a plurality of longitudinal indents. Advantageously, the pair of opposing indents may allow for an expansion of the tubular retaining portion, thereby allowing for a larger volume of foodstuff to be accommodated. 
     n some embodiments, the tubular retaining portion comprises a longitudinally extending tine. The tine may advantageously increase the surface area in contact with a food item present in the tubular retaining portion, thereby increasing the surface adhesion and increasing the likelihood that the food items are retained in the tubular retaining portion. 
     Preferably, the tine protrudes from the posterior end and extends to the anterior end. Preferably, the tine extends longitudinally along a centre of the cross-sectional shape of the tubular retaining portion. Alternatively, the tine may extend longitudinally along any position of the cross-sectional shape. 
     In some embodiments, the tine extends half of a length of the tubular retaining portion such that a tip of the tine is proximate a center of the tubular retaining portion. Alternatively, the tine may extend any length of the tubular retaining portion. 
     The tine may be tubular in shape such that the tine substantially matches the shape of the tubular retaining portion. A radius of the tine may decrease from a base of the tine to the tip of the tine. Other embodiments exist wherein the tine has any shape suitable for providing a surface area. 
     Preferably, the gripping portion further comprises an inner handle gripping portion and an outer gripping portion. 
     Preferably, the outer gripping portion encompasses the inner gripping portion. 
     In preferable embodiments, the gripping portion comprises the same material as the tubular retaining portion. Alternatively, the gripping portion comprises a different material. 
     Preferably, the gripping portion further comprises: a food retaining cavity comprising: a cavity volume; an anterior end; and a posterior end. 
     In some embodiments, the inner handle portion and the tine constitute a single unified structure. The unified structure may comprise a base proximate the posterior end of the gripping portion. The unified structure may extend longitudinally from the gripping portion to the tubular retaining portion. Advantageously, the unified structure may be more robust and may be more straightforward to manufacture than if the tine were separate. 
     Preferably, the inner handle portion comprises the food retaining cavity. In this way, the food retaining cavity may be encompassed by the inner handle portion. 
     In a preferable embodiment, the food retaining cavity and the tubular retaining portion are provided in fluid communication. In this way, food stuff stored in the food retaining cavity may be transported to the retaining portion cavity. 
     Preferably, the tubular retaining portion further comprises a first connection portion proximate the anterior end of the tubular retaining portion. Further preferably, the food retaining cavity further comprises a second connection portion proximate the anterior end of the food retaining cavity. In this way, the first connection portion and the second connection portion connect to facilitate the fluid communication between the tubular retaining portion and the food retaining cavity. 
     Preferably, the tubular retaining portion comprises an attachment means, wherein the attachment means is configured to facilitate the attachment and detachment of the tubular retaining portion from the gripping portion. 
     In some embodiments, the attachment means may be a screw closure. In this way, the tubular retaining portion may be attached to the gripping portion by twisting the tubular retaining portion about the screw closure. 
     Further embodiments exist wherein the attachment means is any attachment means suitable for facilitating the attachment of the tubular retaining portion to the gripping portion. 
     In some embodiments, the gripping portion further comprises a food loading conduit proximate the posterior end of the food retaining cavity, arranged to facilitate the loading of food into the food retaining cavity. In this way, food may be added to the food retaining cavity without detaching the tubular retaining portion. 
     Further embodiments exist wherein the food loading conduit is proximate any suitable part of the food retaining cavity suitable for facilitating the loading of food into the food retaining cavity. 
     Preferably, the food loading conduit is sealable. In this way, the food stuff may be loaded into the food retaining cavity and may be unable to exit the food retaining cavity via the food loading conduit. 
     In preferable embodiments, the inner handle portion is made of a rigid material such that the inner handle portion comprises a first material and the outer gripping portion comprises a second material, wherein preferably the rigidity of the first material is greater than the rigidity of the second material. 
     Preferably, the first material is compressible. In this way, the cavity volume may be altered and as a result, the food stuff present in the food retaining cavity may be expelled into the tubular retaining portion via the first connection portion and the second connection portion. 
     Preferably, the second material comprises a flexible material. In some embodiments, the second material is the same as the tubular retaining portion material. Additional embodiments will be appreciated by the skilled addressee wherein the second material comprises a different material to that of the tubular retaining portion material. Advantageously, the gripping portion is resistant to shear stress that may be introduced by a user of the spill resistant item of cutlery accelerating or decelerating the spill resistant item of cutlery. 
     The above embodiments have been described with the tubular retaining portion having a single retaining portion cavity. However, additional embodiments may be envisaged wherein the tubular retaining portion comprises a plurality of retaining portion cavities. Each retaining portion cavity may be substantially similar. Alternatively, each retaining portion cavity may be distinct. In such an embodiment, the retaining portion cavities may share the same food inlet. Alternatively, the retaining portion cavities may each comprise a food inlet. Similarly, the retaining portion cavities may share the same air vent or may each comprise an air vent. Similarly, the retaining portion cavities may each comprise a tine. Said plurality of retaining portion cavities may advantageously improve food retention of the device. 
     Additional embodiments may be envisaged wherein the spill resistant item of cutlery comprises a plurality of air vents. Alternatively, the spill resistant item of cutlery may comprise no air vents. 
     In an embodiment the spill resistant item of cutlery is arranged such that the tubular retaining portion terminates adjacent to the inner handle portion for a compact arrangement and ease of grip location for the user, whether the user is a carer or an infant or adult self-feeding.

     DETAILED DESCRIPTION OF THE INVENTION 
     When introducing elements of various embodiments of the present invention, the articles “a,” “an,” “the,” and “said” are intended to mean that there are one or more of the elements. The terms “comprising,” “including,” and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements. Any examples of parameters are not exclusive of other parameters of the disclosed embodiments. Components, aspects, features, configurations, arrangements, uses and the like described, illustrated or otherwise disclosed herein with respect to any particular embodiment may similarly be applied to any other embodiment disclosed herein. 
     Referring to  FIG. 1 , a spill resistant item of cutlery, or spoon,  100  is shown. The spill resistant item of cutlery  100  having a longitudinal axis extending therethrough and as illustrated in  FIG. 1 . The device  100  comprises a housing, a tubular retaining portion  101  proximate a first end of the housing or longitudinally extending elongate member. The elongate member has a gripping portion  106  proximate a second end opposing the first end. The device features the tubular retaining portion  101  comprising an interior retaining surface  104  defining a retaining portion cavity  103 . The tubular retaining portion further comprises a food inlet F in fluid communication with the retaining portion cavity  103 . 
     The spoon or spill resistant item of cutlery  100  includes an air vent  102  located in the vicinity of the tubular retaining portion  101  and foodstuff retaining portion of the device, at an angle providing air flow communication in a direction perpendicular to the longitudinal axis of the spill resistant item of cutlery  100 . In the illustrated embodiment the air vent  102  is a circular hole of substantially equal diameter through the material comprising the tubular retaining portion  101  to the interior retaining surface  104  and through to the retaining portion cavity  103 . 
       FIG. 2  shows the gripping portion  106  that comprises the components of a central inner handle gripping portion  105  surrounded and enveloped in an outer gripping portion  106  in  FIG. 2 . The combined apparatus of the inner handle gripping portion  105  surrounded and encompassed by the outer gripping portion  106  should be of one body such that the user can operate and manipulate the handle as one tool. In the embodiment shown, the inner handle gripping portion  105  is made of a rigid material such as a metal or hard plastic, with the outer gripping portion  106  comprising a softer, less rigid second material, such as a flexible plastic or rubber. The outer gripping portion  106  may feature an ergonomic design and shape for ease of operation and handling. There may be alternative sizes and shapes for different skills and sizes of user. In addition, and as illustrated in  FIG. 3 , the second end of the spill resistant item of cutlery  100  is rounded and smoothed to provide a safe and non-damage inflicting surface. The rounded end is arranged to provide an ergonomic handle that is inviting to use and also provides no sharp edges or end which could cause damage while being used and operated at a table or feeding area. 
     With reference to  FIG. 1  and  FIG. 4 , the interior of the tubular retaining portion  101  is shown. The tubular retaining portion  101 , as illustrated, is broadly cylindrical in shape. The tubular retaining portion  101  is open at one end, the so called food inlet F. The tubular retaining portion  101  is such that it defines a retaining portion cavity  103  bounded by an interior retaining surface  104 . The material of the entire portion  101  in the example here is silicone, durable, safe and flexible. The material should be food safe, suitable for cleaning and drying, suitable for human and animal contact and durable and hard wearing, suitable for repeated use, wear and cleaning. For institutional settings and mass use the requirements for the material and the structure to withstand industrial cleaning and drying should also be considered. 
     In alternative embodiments, an upper portion of the tubular retaining portion  101  may comprise a first material and a lower portion of the tubular retaining portion  101  may comprise a second material. The first material may be silicone and the second material may be plastic such that the first material is more flexible than the second material. 
     In the illustrated embodiment of  FIG. 4 , the interior retaining surface  104  can be seen to comprise a plurality of elevations or ribs  104 . As set out previously, the rib structures are arranged so as to maximise surface adhesion between a food stuff or puree present in the tubular retaining portion and the interior retaining surface  104 . The illustrated example in  FIGS. 1 and 4  shows a series of abutting parallel longitudinal protrusions or ribs, extending along the interior retaining surface  104  in a direction parallel and longitudinal relative to the longitudinal axis of the spill resistant item of cutlery  100 . In other embodiments, the plurality of protrusions may comprise a plurality of protrusions extending in any direction along the interior retaining surface. The protrusions or elevations may be set alongside or abutting each other, or may be spaced apart from the next elevation or rib. 
     In use the spill resistant item of cutlery  100  is held and gripped by the user at the gripping portion  106  and the tubular retaining portion is dipped into a bowl or other container of food stuff, or is otherwise loaded with a food stuff (for example a puree or a soft food). The food stuff enters the retaining portion cavity  103  at F and the air previously occupying the volume of the cavity  103  is expelled and urged out of the air vent  102 . The food stuff adheres and surrounds the interior retaining surface  104 . In particular the food stuff sticks to and engages with the ribs  104  of the interior retaining surface  104 . The surface adhesion of the ribs and the food stuff is sufficient to retain the food stuff, within the tubular retaining portion  101 , as the user moves the spill resistant item of cutlery  100  from the bowl towards the mouth. The surface adhesion of the ribs and the food stuff is sufficient to retain the food stuff, within the tubular retaining portion  101 , during any sudden movement such as a jerking or playing movement or a distracted movement. Once the user places the spill resistant item of cutlery  100  to their mouth or the mouth of the subject, the person or animal to be fed, then the food is released into the mouth by a sucking or suckling action or otherwise mouthing at the tubular retaining portion  101 . The food stuff previously occupying the volume of the cavity  103  moves into the mouth of the subject and air replaces the volume removed through incoming air in through the air vent  102 . The loading and feeding operation can then be repeated. When in the mouth and squeezed by the lips and or tongue, food may be evacuated from the cavity  103  via both the open end and via the air vent  102 , thus the bolus of food is released into the mouth. 
     After use, the tubular feeding portion can be cleaned and washed. In some embodiments (not illustrated) the spill resistant item of cutlery  100  can be separated into its component parts for washing, deep cleaning or sterilising. 
     Turning now to  FIG. 5A , a top view of a spill resistant item of cutlery  300  is shown in accordance with an alternative embodiment of the present invention. 
     The spill resistant item of cutlery, or spoon,  300  is substantially similar to the spoon  100  in that the spoon  300  comprises a housing, a tubular retaining portion  301  proximate a first end of the housing or longitudinally extending elongate member. The elongate member comprises a gripping portion  306  proximate a second end opposing the first end. The spoon features the tubular retaining portion  301  comprising an interior retaining surface  304  defining a retaining portion cavity. The tubular retaining portion further comprises a food inlet F in fluid communication with the retaining portion cavity. 
     The spoon  300  includes an air vent  302  located in the vicinity of the tubular retaining portion  301  and foodstuff retaining portion of the device, at an angle providing air flow communication in a direction perpendicular to the longitudinal axis of the spill resistant item of cutlery  300 . In the illustrated embodiment the air vent  302  is a circular hole of substantially equal diameter through the material comprising the tubular retaining portion  301  to the interior retaining surface  304  and through to the retaining portion cavity. 
     The tubular retaining portion  301  further comprises a width. In the illustrated embodiment of the spoon  300 , the width varies along the longitudinal axis. The radius increases along a first portion of the longitudinal axis and decreases along second portion of the longitudinal axis such that the tubular retaining portion  301  is tear-drop or balloon shaped. The retaining portion cavity substantially matches the shape of the tubular retaining portion  301 . 
     In a further alternative embodiment,  FIG. 5B  shows an end view of a spill resistant item of cutlery  400  in accordance with this alternative embodiment of the present invention. 
     The spill resistant item of cutlery, or spoon,  400  is substantially similar to the spoon  100  in that the spoon  400  comprises a housing, a tubular retaining portion  401  proximate a first end of the housing or longitudinally extending elongate member. The elongate member comprises a gripping portion (not shown) proximate a second end opposing the first end. The spoon features the tubular retaining portion  401  comprising an interior retaining surface  404  defining a retaining portion cavity  403 . The tubular retaining portion further comprises a food inlet F in fluid communication with the retaining portion cavity  403 .

     The tubular retaining portion  401  is broadly cylindrical in shape and comprises a substantially circular cross-sectional shape. The tubular retaining portion  401 , as illustrated, is open at one end, the so called food inlet F. The tubular retaining portion  401  is such that it defines a retaining portion cavity  403  bounded by an interior retaining surface  404 . The interior retaining surface  404  can be seen to comprise a plurality of elevations or ribs  404 . The plurality of ribs  404  are a series of abutting parallel longitudinal protrusions or ribs, extending along the interior retaining surface  404  in a direction parallel and longitudinal relative to the longitudinal axis of the spoon  400 . 
     As shown in  FIG. 4 , a rib  406  of the ribs  404  comprises a height substantially greater than a height of the ribs  404 . That is, the rib  406  protrudes further towards a central longitudinal axis of the tubular retaining portion than the ribs  404 . Alternative embodiments exist, wherein the rib  406  extends towards an axis offset from the central longitudinal axis. The illustrated rib  406  comprises a height greater than a radius of the circular cross-sectional shape of the tubular retaining portion  401 . Embodiments may be envisaged, wherein the height is less than the radius of the cross section. Further embodiments may be envisaged wherein the height of the rib  406  varies along the longitudinal axis. The surface area of the interior retaining surface  404  is further increased, thereby increasing the surface adhesion and further increasing the bias for food items to remain within the tubular retaining portion  401 . 
     There may be a plurality of ribs  406 , wherein each may protrude towards the same, or different longitudinal axes. The ribs  406  may each comprise a different, or the same height. 
     With reference to  FIG. 5C , a side sectional view of a spill resistant item of cutlery  500  in accordance with another alternative embodiment of the present invention is shown. 
     The spill resistant item of cutlery  500 , or spoon  500 , is substantially similar to the spoon  100  in that the spoon  500  comprises a housing, a tubular retaining portion  501  proximate a first end of the housing or longitudinally extending elongate member. The elongate member comprises a gripping portion  506  proximate a second end opposing the first end. The gripping portion  506  comprises the components of a central inner handle gripping portion  505  surrounded and enveloped in an outer gripping portion  506 . 
     The spoon also features the tubular retaining portion  501  comprising an interior retaining surface  504  defining a retaining portion cavity  503 . The tubular retaining portion further comprises a food inlet F in fluid communication with the retaining portion cavity  503 .

       FIG. 5D  shows a top view of a spill resistant item of cutlery  600  in accordance with an alternative embodiment of the present invention comprising a cuff. 
     The spill resistant item of cutlery  600 , or spoon  600 , is substantially similar to the spoon  100  in that the spoon  600  comprises a housing, a tubular retaining portion  601  proximate a first end of the housing or longitudinally extending elongate member. The elongate member comprises a gripping portion  606  proximate a second end opposing the first end. The gripping portion  606  comprises the components of a central inner handle gripping portion (not shown) surrounded and enveloped in an outer gripping portion  606   
     The spoon also features the tubular retaining portion  601  comprising an interior retaining surface  604  defining a retaining portion cavity  603 . The tubular retaining portion further comprises a food inlet F in fluid communication with the retaining portion cavity  603 . 
     The spoon  600  includes an air vent  602  located in the vicinity of the tubular retaining portion  601  and foodstuff retaining portion of the device, at an angle providing air flow communication in a direction perpendicular to the longitudinal axis of the spill resistant item of cutlery  600 . In the illustrated embodiment, the air vent  602  is a circular-like hole of substantially equal diameter through the material comprising the tubular retaining portion  601  to the interior retaining surface  604  and through to the retaining portion cavity  603 . 
     The tubular retaining portion  601  comprises a volume having a substantially circular cross-sectional shape having a radius. 
     The spoon  600  further comprises a cuff  612 . The cuff  612  is cylindrical in shape and comprises a hollow center such that a cross section of the cuff  612  is annular. The cuff  612  envelops a portion of an outer surface of the spoon  600 . The cuff  612  comprises an indent  614  substantially similar in shape to the air vent  602 . The indent  614  is positioned such that air flow is possible between the air vent and the exterior. The cuff  612  further comprises a depth extending orthogonally from the exterior surface of the spoon. 
     In some embodiments, the cuff  612  is rotatable. In such an embodiment, rotating the cuff  612  between a first position and a second position allows for the air vent  602  to be substantially covered in the first position and substantially uncovered in the second position. 
     In an alternative embodiment, and with reference to  FIG. 6 , there is shown a side sectional view of a spill resistant item of cutlery  700  in accordance with an alternative embodiment of the present invention. The embodiment shown in  FIG. 6  is substantially similar to the embodiments shown in  FIGS. 1 to 4 , but differs in that the gripping portion  702  is a pouch  702  comprising food retaining cavity  704 . The food retaining cavity  704 , which is substantially cylindrical in shape, comprises a cavity volume, a posterior end  706  and an anterior end  708 . Proximate to the posterior end  706  of the food retaining cavity  704 , there is a second connection portion  710 . Proximate the anterior end  708  of the food retaining cavity  704 , there is a food loading conduit  712 , configured to facilitate the loading of food stuff into the food retaining cavity  704 . The food loading conduit  712  is sealable such that it does not allow food stuff to escape the food retaining cavity  706  via the food loading conduit  712 . In the embodiment shown in  FIG. 6 , the pouch  702  is made of a compressible material. 
     Further, in the embodiment shown on  FIG. 6 , a tubular retaining portion  720  is shown, substantially similar to the tubular retaining portion  101  as shown in  FIGS. 1 to 4 . The tubular retaining portion  720  comprises a first connection portion  722  proximate a retaining portion cavity  724 . Both connection portions  722 ,  710  are substantially tubular in shape and extend along the longitudinal axis of their respective housings  702 ,  724 . The first connection portion  722  is aligned with the second connection portion  710  such that a channel is formed between the connection portions  710 ,  722  so as to facilitate fluid communication between the retaining portion cavity  724  and the food retaining cavity  704 . 
     In use, the food retaining cavity is filled with food stuff (for example a puree or a soft food) via the food loading conduit  712  by, for example, pouring the food stuff into the food loading conduit  712 . The food loading conduit  712  is then sealed such that the food stuff cannot escape the food retaining cavity  704  via the food loading conduit  712 . The gripping portion  702  is then squeezed, resulting in the compression of the food cavity  704 . Said compression leads to the cavity volume of the food retaining cavity  704  decreasing, thereby reducing the volume to surface area ratio of the food retaining cavity  704 . As a result, a volume of food stuff is ejected from the food retaining cavity  704  equal to the reduction in food retaining cavity volume (assuming the food stuff occupied the full volume of the food retaining cavity). The food stuff is ejected via the second connection portion  710  and the first connection portion  722 , into the retaining portion cavity  724 , due to the fluid communication between the food retaining cavity  704  and retaining portion cavity  724 . 
     The food stuff enters the tubular retaining portion  720  and the air previously occupying the volume of the cavity  724  is expelled and urged out of an exit hole  726  and an air vent  728 . The food stuff adheres and surrounds the interior retaining surface of the cavity  724 . In particular the food stuff sticks to and engages with the ribs  730  of the interior retaining surface. The surface adhesion of the ribs  730  and the food stuff is sufficient to retain the food stuff, within the tubular retaining portion  720 , as the user moves the spill resistant item of cutlery  700  towards the mouth. The surface adhesion of the ribs  730  and the food stuff is sufficient to retain the food stuff, within the tubular retaining portion  720 , during any sudden movement such as a jerking or playing movement or a distracted movement. Once the user places the spill resistant item of cutlery  700  to their mouth or the mouth of the subject, the person or animal to be fed, then the food is released into the mouth by a sucking or suckling action or otherwise mouthing at the tubular retaining portion  720 . The food stuff previously occupying the volume of the cavity  724  moves into the mouth of the subject and air replaces the volume removed through incoming air in through the air vent  728 . The loading and feeding operation can then be repeated. When in the mouth and squeezed by the lips and/or tongue, food may be evacuated from the cavity  724  via both the exit hole  726  and via the air vent  728 , thus the bolus of food is released into the front of the mouth. 
     With reference to  FIG. 7 , shown is another alternative embodiment similar to the embodiment shown in  FIG. 6 , wherein the tubular retaining portion  820  is detachable from the pouch  802 . In the embodiment shown, the pouch  802  and the tubular retaining portion  820  are separated. Within the first connection portion  822  of the tubular retaining portion  820 , there is an internal helical thread  902 . Surrounding the second connection portion  810  of the pouch  802 , there is an external screw thread  904  configured to engage with the internal helical thread  902 . 
     In use, the second connection portion  810  is positioned inside the first connection portion  822  and a torque is applied by twisting the tubular retaining portion  820  (or by twisting the pouch  802 ). The internal helical thread  902  engages with the external screw thread  904 , causing the tubular retaining portion  820  to attach to the pouch  802 . 
     In a further embodiment (not shown), the gripping portion comprises a seal proximate the second connecting portion. In this way, the seal stops any food stuff contained within the food retaining cavity escaping via the second connecting portion when the gripping portion and the tubular retaining portion are unattached. The tubular retaining portion comprises a piercing member proximate the first connecting portion, configured to pierce the seal of the gripping portion following the attachment of the tubular retaining portion to the gripping portion. In this way, the attachment process may allow fluid communication between the tubular retaining portion and the gripping portion. 
       FIG. 8  is a lateral view of a further example of a spill resistant item of cutlery  900 . The spill resistant item of cutlery  900  has no air vent and is substantially similar to the spill resistant feeding item of cutlery  100  (See  FIG. 1 ) in shape and outer construction. 
     The device  900  comprises a substantially tubular silicone outer portion  910  and a tubular retaining portion  901  proximate a first end of the outer portion  910 . The outer portion  910  has a gripping portion  906  proximate a second end opposing the first end. The device  900  features the tubular retaining portion  901  comprising an interior retaining surface  904  defining a retaining portion cavity  903 . The tubular retaining portion further comprises a food inlet F in fluid communication with the retaining portion cavity  903 . The outer portion  910  further comprises an annular protrusion  912 , creating a passage  913 . 
     The device  900  further comprises an inner portion  914  extending along an interior of the outer portion  910 . The inner portion  914  comprises for example, a more rigid material than the outer portion  910  so as to provide support to the more flexible outer portion  910 . The inner portion comprises a head portion  916 , a neck portion  918  and a base portion  920 . The head portion  916  comprises a plurality of grooves or indents  917 . A maximum width of the head portion is greater than a width of the passage  913 , but less than a width of the tubular retaining portion  901 . Adjacent to the head portion  916 , the inner portion  914  comprises the neck portion  918 . The neck portion  918  comprises a neck width that is less than the width of the passage  913 . Adjacent to the neck portion  918 , and opposing the head portion  916 , the inner portion  914  comprises the base portion  920 . The base portion  920  extends longitudinally from the neck portion  918  to a posterior end of the inner portion  914 . A width of the base portion  920  increases along the longitudinal axis. 
     In use, the inner portion  914  and the outer portion  910  may be connected/disconnected. Connecting or inserting may be achieved by a press-fit, push fit or a bayonet type fitting. That is, for example, the flexibility of the outer portion  910  allows for the head portion  916  to push through to a connected or disconnected configuration. 
     In the connected configuration, the grooves  917  create channels between the inner portion  914  and the outer portion  910 . The channels allow airflow out of the tubular retaining portion, thereby preventing a build-up of negative pressure. The channels comprise a resistance that is great enough to inhibit food items from passing through the channels.
