    Fuel Tank Cap and Fuel Tank TECHNICAL FIELDThe present invention relates to a fuel tank cap. The present invention further relates to afuel tank comprising a fuel tank cap.
    BACKGROUNDA fuel tank of a vehicles comprises a filling opening which is open during filling of the fueltank with fuel. After filling the fuel tank, the filing opening is closed off with a fuel tank cap.
    US 6209745 discloses a seal cap for a gas tank, the gas tank including an outer sleeve. Theseal cap comprises outer threads engaging with internal threads of the outer sleeve. Theseal cap comprises a lid arranged on a spring-loaded shaft. The lid is adapted to be movedbetween an outer pop up position and an inner flush position thereof, in which the lid is flushwith the gas tank's outer surface. ln the outer pop up position of the lid, the seal cap may berotated by a user to close and open the gas tank. ln various vehicles it may be difficult to distinguish whether the fuel tank cap of a fuel tank isopen or closed. ln particular, when the fuel tank cap is positioned in an opening apertureforming the filling opening of the fuel tank, such distinguishing may be difficult under badlyilluminated conditions. Thus, the person filling the fuel tank may accidentally leave the fueltank cap sitting unclosed in the opening aperture after the filling of the fuel tank.
    SUMMARYlt is an object of the invention to provide a fuel tank cap, which clearly indicates to a userwhether the fuel tank cap is open or closed.
    According to an aspect of the invention, the object is achieved by a fuel tank cap for closingand opening an opening aperture of a fuel tank, the fuel tank cap comprising a first partconfigured to rotatably engage with the fuel tank at the opening aperture thereof, and asecond part movably engaged with the first part. The second part has a first position and asecond position in relation to the first part. ln the first position a cover portion of the secondpart is closer to the first part than in the second position. A first surface of the first part faces the cover portion, and the cover portion extends substantially in parallel with the first surface.
    The first surface has a first colour and the cover portion has a second colour different fromthe first colour. Further, either: 2 in the first position the cover portion covers the first surface such that only thesecond colour of the first and second colours is visible to a viewer or that a mixed colour ofthe first and second colours is visible to viewer, and in the second position both the first andsecond colours are visible to a viewer, or in the first position the cover portion covers the first surface such that a mixedcolour of the first and second colours is visible to a viewer, and in the second position onlythe second colour of the first and second colours is visible to a viewer. The first position ofthe second part is associated with the fuel tank cap sealing the opening aperture of the fueltank and the second position of the second part is associated with the fuel tank cap releasingthe opening aperture of the fuel tank.
    Since the first surfaced has a first colour and the cover portion has a second colour, and thearrangement of the second part having the first and second positions for different colours tobe visible to a viewer depending on, in which of the first and second position the second partis positioned, and since the first position of the second part is associated with the fuel tankcap sealing the opening aperture of the fuel tank and the second position of the second partis associated with the fuel tank cap releasing the opening aperture of the fuel tank, differentcolours are visible to a user of the fuel tank cap depending on whether the fuel tank cap isopen, i.e. releasing the opening aperture of the fuel tank, or the fuel tank cap is closed, i.e.sealing the opening aperture of the fuel tank. As a result, the above mentioned object isachieved.
    The opening aperture of the fuel tank forms a filling opening of the fuel tank, i.e. an openingthrough which the fuel tank may be filled with fuel. The first part of the fuel tank cap, eitherdirectly or indirectly, may seal the opening aperture of the fuel tank when the fuel tank capcloses the fuel tank. Alternatively, or additionally, the second part of the fuel tank, eitherdirectly or indirectly, may seal the opening aperture of the fuel tank when the fuel tank capcloses the fuel tank. The first surface being visible to a viewer means that the first surface isvisible to the viewer at least from a viewing angle at a side laterally of the fuel tank cap. Thecover portion of the second part may suitably completely cover the first surface in the firstposition of the second part. The second part is connected to the first part in both the first andsecond positions of the second part. ln the second position of the second part both the firstsurface and the cover portion may be visible to a user and thus, both the first and secondcolours may be visible to the user, indicating that the fuel tank cap has released the openingaperture of the fuel tank. Alternatively, in the second position of the second part only thecover portion may be visible to a user and thus, only the second colour may be visible to theuser, indicating that the fuel tank cap has released the opening aperture of the fuel tank. ln 3 the first position of the second part the first colour is not visible to a user. Only one colour isvisible to a user at the cover portion of the second part. This may be the second colour, or amixed colour of the first and second colours. The fuel tank cap having released the openingaperture of the fuel tank means that the fuel tank cap does not seal the opening aperture ofthe fuel tank. The fuel tank cap sealing the opening aperture of the fuel tank means that thefuel tank cap prevents fuel from leaking out of the fuel tank through the opening aperture.
    According to embodiments, the cover portion may comprise a translucent portion tinted in thesecond colour such that in the first position of the second member the mixed colour of thefirst and second colours is visible to a viewer. ln this manner a convenient arrangement maybe provided for indicating to a user that the fuel tank cap seals the opening aperture of thefuel tank. The mixed colour may be a distinctly different colour than any one of the first andsecond colours thus, clearly indicating to a viewer/user that the second part is in its firstposition. lf for instance the first and second colours are yellow and blue, the mixed colourmay be green, or if the first and second colours are yellow and red, the mixed colour may be orange.
    According to embodiments, the fuel tank cap has a centre axis extending centrally throughthe first part and the second part, and about which centre axis at least the first part mayrotate to engage with the opening aperture of the fuel tank. The second part may be rotatablyengaged with the first part such that a movement of the second part in relation to the first partalong the centre axis actuates a relative rotation between the first and second parts aboutthe centre axis. ln this manner a user may rotate the first part about the centre axis bymoving the second part along the centre axis, e.g. by pushing against the second part. ln thisrespect it may be mentioned that the first part may suitably engage with the fuel tank in theopening aperture of the fuel tank. For instance, the first part may comprise an externallyarranged interlocking member configured to engage with a complementing member in theopening aperture of the fuel tank.
    According to embodiments, the fuel tank cap may comprise a spring member arrangedbetween the first part and the second part biasing the second part in a direction away fromthe first part. The biasing by the spring member may achieve a movement of the second partin relation to the first part along the centre axis from the first position to the second position.ln this manner the spring member, suitably triggered by a user, may cause the fuel tank capto release the opening aperture of the fuel tank. The spring member biasing the second partin a direction away from the first part may ensure that a user may have to take an active 4 measure in order to move the second part from its second position to its first position, suchas e.g. pushing against the second part.
    According to embodiments, the first part may comprise an internally threaded portion and thesecond part may comprise at least one external protrusion engaging with the internallythreaded portion. Alternatively, the first part may comprise at least one internally arrangedprotrusion and the second part may comprise an externally arranged threaded portion. ln thismanner the relative rotation between the first and second parts about the centre axis may beachieved when the second part is moved in relation to the first part along the centre axis.
    According to embodiments, the second part may comprise at least one rotation preventingmeans configured to engage with the fuel tank to prevent a rotation of the second partaround the centre axis of the fuel tank cap. ln this manner the second part may be preventedfrom rotating when the at least one rotation preventing means engages with the fuel tank.Thus, the above mentioned relative rotation between the first and second parts about thecentre axis may result in a rotation of the first part about the centre axis while the second partengages with the fuel tank. Accordingly, the rotation of the first part may be utilised forclosing and opening the fuel tank cap, i.e. the first part being rotated to engage with theopening aperture of the fuel tank, and to disengage with the opening aperture of the fuel tank According to embodiments, the fuel tank may comprise a locking member configured toreleasably lock the second part in its first position. ln this manner it may be ensured that thesecond part remains in its first position until a user releases the second part. Accordingly, thefuel tank cap may remain engaged with the opening aperture of the fuel tank until a userreleases the second part.
    According to a further aspect of the invention, there is provided a fuel tank comprising anopening aperture and a fuel tank cap configured to releasably close the opening aperture.The fuel tank cap is a fuel tank cap according to any one aspect and/or embodimentsdiscussed herein. lt is a further object of the invention to provide a fuel tank cap, which is easily opened andclosed.
    According to a further aspect of the invention, the object is achieved by a fuel tank cap forclosing and opening an opening aperture of a fuel tank, the fuel tank cap comprising: 5 a first part configured to rotatably engage with the fuel tank at the openingaperture thereof, a second part movably engaged with the first part, and a spring member arranged between the first part and the second part biasingthe second part in a direction away from the first part. The second part has a first positionand a second position in relation to the first part. ln the first position the second part is closerto the first part than in the second position. The fuel tank cap has a centre axis extendingcentrally through the first part and the second part, and about which centre axis at least thefirst part rotates to engage with the opening aperture of the fuel tank. The second part isrotatably engaged with the first part such that a movement of the second part in relation tothe first part along the centre axis actuates a relative rotation between the first and secondparts about the centre axis.
    Since by moving the second part along the centre axis the first part is rotated about thecentre axis, the rotation of the first part may be utilised to engage the fuel tank cap with theopening aperture of the fuel tank, and to disengage the fuel tank cap from the openingaperture of the fuel tank. As a result the object is achieved.
    For instance, a user may push against the second pan to engage the first part with theopening aperture, and the spring member biasing the second part in the direction away fromthe first part may disengage the first part from the opening aperture. The first part maycomprise an externally arranged interlocking member configured to engage with acomplementing member in the opening aperture of the fuel tank in order to bring about theengagement with, and disengagement from, the opening aperture. For instance, there maybe provided a threaded connection between the first part and the opening aperture, or theremay be provided a bayonet mount between the first part and the opening aperture.
    According to embodiments, the biasing by the spring member may achieve a movement ofthe second part in relation to the first part along the centre axis from the first position to thesecond position According to embodiments, the first part may comprise an internally threaded portion and thesecond part may comprise at least one external protrusion engaging with the internallythreaded portion.

    Above, two aspects of an invention related to a fuel tank cap have been discussed: oneaspect related to the indication of whether a fuel tank cap is open or closed, and one aspectrelated to a mechanism for opening and closing the fuel tank cap. Generally, fuel tank capsaccording to both aspects may utilise features of the various embodiments discussed herein.Accordingly, the features of, and advantages with, the present invention discussed in thefollowing detailed description relate to both aspects of the invention.
    BRIEF DESCRIPTION OF THE DRAWINGS Various aspects of the invention, including its particular features and advantages, will bereadily understood from the example embodiments discussed in the following detaileddescription and the accompanying drawings, in which: Fig. 1 illustrates a side view of a fuel tank cap according to embodiments, Fig. 2 illustrates a cross section through the fuel tank cap of Fig. 1, Fig. 3 illustrates embodiments of a locking member of a fuel tank cap, Fig. 4 illustrates a partial cross section through the fuel tank cap of Figs. 1 and 2, Figs. 5 and 6 illustrates embodiments of fuel tank caps, and Fig. 7 illustrates schematically a fuel tank according to embodiments.
    DETAILED DESCRIPTION 8 Aspects of the present invention will now be described more fully. Like numbers refer to likeelements throughout. Well-known functions or constructions will not necessarily be describedin detail for brevity and/or clarity.
    Fig. 1 illustrates a side view of a fuel tank cap 2 according to embodiments. The fuel tankcap 2 is configured for closing and opening an opening aperture of a fuel tank. The fuel tankcap 2 comprises a first part 4 configured to rotatably engage with the fuel tank at the openingaperture thereof, and a second part 6 movably engaged with the first part 4. A springmember 8 is arranged between the first part 4 and the second part 6. The spring member 8biases the second part 6 in a direction away from the first part 4.
    The first part 4 comprises an externally arranged interlocking member configured to engagewith a complementing member in the opening aperture of the fuel tank. ln theseembodiments the interlocking member comprises threads 10 forming part of a threadedconnection between the first part 4 and the opening aperture. Alternatively, there may e.g. beprovided a bayonet mount between the first part 4 and the opening aperture.
    The threads 10 may seal against the fuel tank in order to prevent fuel from leaking throughthe opening aperture of the fuel tank when the fuel tank cap 2 closes the opening aperture.However, a sealing may be provided in connection with the first part 4. The sealing it maye.g. be in the form of a rubber gasket 12 provided around the first part 4 to ensure a tightseal against the fuel tank. A further alternative, or a complement to the above discussedseals, may be that the second part 6 seals against the fuel tank.
    The fuel tank cap 2 has a centre axis 14 extending centrally through the first part 4 and thesecond part 6. The first part 4 is rotatable about the centre axis 14 in order to engage anddisengage with the opening aperture of the fuel tank. That is, as the first part 4 is rotatedwithin the opening aperture of the fuel tank, the threads 10 engage with the complementingmember in the opening aperture of the fuel tank. ln an opposite direction of rotation thethreads 10 disengage the complementing member of the opening aperture.
    Fig. 2 illustrates a cross section through the fuel tank cap 2 of Fig. 1, along line ll-ll in Fig. 1.ln the following reference will be made to both Figs. 1 and 2. The second part 6 is rotatablyengaged with the first part 4. A movement of the second part 6 in relation to the first part 4along the centre axis 14 actuates a relative rotation between the first and second parts 4, 6about the centre axis 14. lf for instance the second part 6 is moved linearly from the positionshown in Fig. 2 towards the first part 4, against the biasing of the spring member 8, the 9 engagement between the first and second parts 4, 6 causes the first part 4 to rotated in aclockwise direction seen along the centre axis 14 in a direction towards the top of the fueltank cap 2 and an opening aperture 52 of a fuel tank 50 to be engaged. The biasing of thespring member 8 biases the second part 6 in a linear direction away from the first part 4,which causes the first part 4 to rotate in the opposite direction. ln a first position of thesecond part 6, the spring member 8 has been compressed to such an extent that the secondpart 6 is positioned close to the first part 4. ln a second position of the second part 6, thesecond part 6 is positioned at a distance from the first part 4, i.e. as illustrated in Fig. 2.Accordingly, the biasing by the spring member 8 achieves a movement of the second part 6in relation to the first part 6 along the centre axis 14 from the first position to the secondposition. ln order to seal a fuel tank, a user has to position the fuel tank cap 2 at the opening apertureof the fuel tank and move the second part 6 from its second position to its first position, whichwill cause the first part 4 to rotate as mentioned above. ln doing so, a user has to overcomethe biasing force of the spring member 8. ln practice, a user may simply push against thesecond part 6 to overcome the biasing force.
    The rotation of the first part 4 about the centre axis 14 by the linear movement of the secondpart 6 along the centre axis 14 may be brought about in the following manner. The first part 4comprises an internally threaded portion 16 and the second part 6 comprises at least oneexternal protrusion 18 engaging with the internally threaded portion. As the second part 6 isrotationally locked, and moved along the centre axis 14 towards the first part 4, the internallythreaded portion of the first part 4 follows along the external protrusion of the second part 6thus, rotating the first part 4. ln the embodiments illustrated in Fig. 2 the internally threadedportion 16 comprises an inclined slot 20 running along an inner surface of the first part 4. Theexternal protrusion 18 of the second part 6 extends into the inclined slot 20. ln the alternativeembodiments, the first part 4 may comprise at least one internally arranged protrusion, andthe second part 6 may comprise an externally arranged threaded portion. The at least oneinternally arranged protrusion of the first part 4 will follow along the externally arrangedthreaded portion of the second part 6 as the second part 6 is moved along the centre axis 14thus, rotating the first part 4.
    The second part 6 comprises at least one rotation preventing means 24 configured toengage with the fuel tank 50 to prevent a rotation of the second part 6 around the centre axis14 of the fuel tank cap 2. Thus, the second part 6 may be prevented from rotating whenmoved linearly in relation to the first part 4. ln these embodiments, the rotation preventing means 24 comprises an elongated member 26 extending substantially in parallel with thecentre axis 14 and being configured to engage with the fuel tank 50 by extending into afurther aperture 27 of the fuel tank 50. More specifically, in these embodiments the rotationpreventing means 24 comprises two elongated members 26, each extending into a furtheraperture 27 of the fuel tank 50.
    The second part 6 may be pivotably connected to the elongated member 26 for pivoting thefuel tank cap 2 about an axis 22 extending at a right angle to the centre axis 14. ln thismanner the fuel tank cap 2 may be pivoted about the axis 22 when the fuel tank cap 2 hasbeen moved in a direction of the centre axis 14 out of the opening aperture 52 of the fueltank 50 to such a degree that the first part 4 clears the opening aperture 52 while theelongated member 26 remains in the further aperture 27 of the fuel tank 50. ln suchembodiments the elongated member 26 suitably has a length exceeding the length of thefuel tank cap 2. The pivoting about the axis 22 permits a fuel filling nozzle to be inserted intothe opening aperture 52 for filling the fuel tank 50 without removing the iuel tank cap 2 fromthe fuel tank. ln order to maintain the second part 6 in its first position, and to prevent the spring member 8from unintentionally moving the second part 6 into the second position thus, unintentionallyopening the fuel tank cap 2, the fuel tank cap 2 comprises a locking member 28 configured toreleasably lock the second part 6 in its first position. When locked by the locking member 28,a user has to actively release the locking member 28.
    Fig. 3 illustrates schematically embodiments of a locking member 28 as discussed above.The locking member 28 comprises a engagement member 30 and a projection 32, whereinone of the engagement member 30 and the projection 32 is associated with the first part andthe other of the engagement member 30 and the projection 32 is associated with the secondpart, and wherein the engagement member 30 engages with the projection 32 in the firstposition of the second part. ln this manner, the engagement between the engagementmember 30 and the projection 32 ensure that the locking member 28 locks the second part inits first position resisting the biasing force of the spring member. For instance, the projection32 may protrude in the inclined slot 20 of the first part, and the engagement member 30 mayform part of the external protrusion 18, see Fig. 2. The locking member 28 may operate inthe following manner: The engagement member 30 slides along the inclined slot 20 towardsthe projection 32. At position 30 - 2 the engagement member 30 has passed the projection32 and has been biased by the spring member to engage with the projection 32. ln order torelease the locking member 28, the second part is pushed by a user against the biasing force 11 of the spring member until the engagement member 30 reaches the position 30 - 3. Oncethe second part is released again the engagement member 30 will slide along the inclinedslot 20' urged by the biasing force of the spring member, as indicated at position 30 - 4. Theoperation of the locking member 28 may be compared to that of the locking mechanism of aballpoint pen.
    Referring to Figs. 1 and 2, a first surface 34 of the first part 4 faces the second part 6. Thesecond part 6 comprises a cover portion 36. ln these embodiments, both the first surface 34and the cover portion 36 extend circumferentially around the respective first and secondparts 4, 6. The cover portion 36 extends substantially in parallel with the first surface 34. lnthe second position of the second part 6, as illustrated in Figs. 1 and 2, the first surface 34 isvisible to a viewer, i.e. the first surface is unobstructed by the cover portion 36. Namely, theviewer may see the first surface 34 from a lateral side of the fuel tank cap 2. The first surface34 has a first colour and the cover portion 36 has a second colour different from the firstcolour. The first position of the second part 6 is associated with the fuel tank cap sealing theopening aperture of the fuel tank and the second position of the second part 6, shown inFigs. 1 and 2, is associated with the fuel tank cap 2 releasing the opening aperture of thefuel tank.
    Fig. 4 illustrates schematically a partial cross section through the fuel tank cap 2 of Figs. 1and 2 with the second part 6 in its first position. Referring to Figs. 2 and 4 alternativeembodiments will be discussed in the following. According to one embodiment the coverportion 36 is opaque. ln such an embodiment, in the first position of the second part 6 thecover portion 36 covers the first surface 34 such that only the second colour of the first andsecond colours is visible to a viewer (Fig. 4), and in the second position of the second part36 both the first and second colours are visible to a viewer (Fig. 2). According otherembodiments, the cover portion 36 comprises a translucent portion tinted in the secondcolour. ln such embodiments, in the first position the cover portion covers the first surfacesuch that a mixed colour of the first and second colours is visible to viewer(Fig. 4), and in thesecond position both the first and second colours are visible to a viewer(Fig. 2).
    According to further embodiments, schematically illustrated in Fig. 5, the cover portion 36again comprises a translucent portion tinted in the second colour. ln these embodiments, thesecond part 6 comprises a flange 38 extending along a direction of the centre axis 14. Theflange 38 extends circumferentially around the second part 6. The flange 38 also extendscircumferentially around the first part 4. The flange 38 extends along the direction of thecentre axis 14 to such an extent that the first surface 34 is obstructed to a viewer by the 12 flange 38, when the second part 6 is in its second position. Accordingly, in theseembodiments, in the first position of the second part 6 the cover portion 36 covers the firstsurface 34 such that a mixed colour of the first and second colours is visible to viewer, and inthe second position of the second part 6 only the second colour of the first and secondcolours is visible to a viewer, as illustrated in Fig. 5.
    Returning to Fig. 4 The fuel tank cap 2 comprises a lock 35 configured to lock the secondpart 6 to the first part 4 in the first position of the second part 6 by means of the a removablekey member 37. ln this manner unauthorised opening of the fuel tank may be prevented.
    Fig. 6 illustrates a fuel tank cap 2 according to embodiments. The fuel tank cap 2 resemblesin much the fuel tank cap 2 of the previous embodiments. ln the following inter alia the maindifferences with the previous embodiments will be discussed. The second part 6 comprises aflange 38 extending along a direction of the centre axis 14. ln these embodiments therotation preventing means 24 comprises a slotted member 40 extending in parallel with thecentre axis 14. The slotted member 40 is provided with an elongated slot 42 extending alonga direction of the centre axis 14. Into the elongated slot 42 a pin 44 extends. The pin 44 isfixedly connected to the fuel tank. Accordingly, the second part 6 is prevented from rotatingabout the centre axis 14.
    On the opposite side of the fuel tank cap 2 a corresponding slotted member with anelongated slot may be provided, into which also a pin extends. The pins 44 extending into theelongated slots 42 being fixedly connected to the fuel tank thus, when the fuel tank cap 2 islifted out of the opening aperture by a user until the pins 44 are in the position illustrated inFig. 6, the fuel tank cap 2 may be pivoted about the pins 44. ln these embodiments theflange 38 comprises the slotted member 40.
    Fig. 7 illustrates schematically a fuel tank 50 according to embodiments. The fuel tank 50comprises an opening aperture 52 and a fuel tank cap 2 configured to close the openingaperture 2. The fuel tank cap 2 is a fuel tank cap according to any one aspect and/orembodiments discussed herein. The opening aperture 52 forms a filling opening of the fueltank 50.
    According to embodiments, the fuel tank cap 2 may remain attached to the fuel tank 50 whenthe opening aperture 52 is open. For instance the elongated member 26 of the rotationalpreventing means 24 discussed in connection with Fig. 2 may be provided with elementsconfigured to retain the fuel tank cap 2 at the fuel tank 50. Similarly, the pins 44 of the 13 rotation preventing means 24 discussed in connection with the embodiments of Fig. 6 retainthe fuel tank cap 2 at the fuel tank 50.
    According to embodiments, the fuel tank cap 2 may be pivotable about an axis extending at aright angle to a centre axis of the fuel tank cap 2 when the opening aperture 52 is open. Forinstance, this may be achieved with a fuel tank cap 2 as discussed in connection with Fig. 2,wherein the axis 22 extends at a right angle to the centre axis 14 of the fuel tank cap 2.Alternatively, this may be achieved with the slotted members 40 and the things 44 discussedin connection with Fig. 6. lt is to be understood that the foregoing is illustrative of various example embodiments andthat the invention is defined only by the appended claims. A person skilled in the art willrealize that the example embodiments may be modified, and that different features of theexample embodiments may be combined to create embodiments other than those describedherein, without departing from the scope of the present invention, as defined by theappended claims. The spring 8 biasing the second part 6 in a direction away from the firstpart 4 may for instance be a helical spring as illustrated, but may alternatively comprise anyother resilient element such as e.g. a rubber element or gas spring.
    As used herein, the term "comprising" or "comprises" is open-ended, and includes one ormore stated features, elements, steps, components or functions but does not preclude thepresence or addition of one or more other features, elements, steps, components, functionsor groups thereof.
