Thesecond claw portion 17 is provided projecting rearward from the upper end (the tip end) side of the lockingmember 18. - As shown in
FIGS. 1 to 6 , the lockingmember 18 may be disposed along the outer peripheral surface of the rear side of thespout formation member 13. In addition, the lower end (base end) portion of the lockingmember 18 is supported so as to be capable of freely rotating by ahinge portion 21 provided on thespout formation member 13. In addition, amanipulation portion 18 c (refer toFIG. 9(a) ), which has a concave portion or a convex portion for facilitating rotating manipulation of the lockingmember 18 with a user's finger, is provided in the upper end (tip end) portion of the lockingmember 18. - As shown in
FIG. 8 , ashaft opening 22, into which the pair ofsupport shafts 19 are fitted, and atarget abutting portion 23, against which theelastic piece 20 abuts, are provided in thespout formation member 13. Theshaft opening 22 is provided passing through arib wall 13 g that projects along the outer peripheral surface of the rear side of thespout formation member 13 from the upper surface of anintermediate flange portion 13 f, which is positioned above the lowerside flange portion 13 c. Thetarget abutting portion 23 is formed by therib wall 13 g, which is positioned above theshaft opening 22. - The
hinge portion 21 supports the lower end (base end) of the lockingmember 18 so as to be capable of freely rotating in a state in which therib wall 13 g is held between the pair ofarm portions 18 a by the pair ofsupport shafts 19 being fitted into the inner side of the shaft opening 22 from both ends of theshaft opening 22. - In addition, when the tip end side of the locking
member 18 is rotated toward a forward (one way in a rotating direction) side, the lockingmember 18 is biased toward a rearward (the other way in the rotating direction) side while theelastic piece 20 becomes elastically deformed by theelastic piece 20 abutting against thetarget abutting portion 23. Additionally, in thespout detachment mechanism 15, it is possible to adjust the biasing force when the above-mentionedelastic piece 20 becomes elastically deformed by altering the length and thickness of theelastic piece 20. - In addition, a circumstance in which the locking
member 18 becomes inclined is prevented byextended portions 18 d (refer toFIG. 9(a) ), which extend from the front sides of the pair ofarm portions 18 a of the lockingmember 18, coming into surface contact with the lower surface of astep portion 13 h, which projects from the rear side of theperipheral wall portion 13 b of thespout formation member 13. - As shown in
FIGS. 2 to 6 , thespout detachment mechanism 15 includes a firsttarget locking portion 24 on the front side of the capmain body 8, and a secondtarget locking portion 25 on the rear side of the capmain body 8. The firsttarget locking portion 24 and the secondtarget locking portion 25 are composed of stepped portions that are respectively provided in front and rear positions along theopening portion 8 b of theupper wall portion 8 c. - In the
spout detachment mechanism 15, thespout formation member 13 is fitted from the lower side into the inner side of theopening portion 8 b of the capmain body 8 in a state in which thefirst claw portion 16 is positioned with respect to the firsttarget locking portion 24. At this time, a state in which the pair of upperside flange portions 13 d abut against the lower surface of theupper wall portion 8 c of the capmain body 8 is attained. In addition, thefirst claw portion 16 is locked with the firsttarget locking portion 24. Furthermore, as thesecond claw portion 17 rides over the edge of theopening portion 8 b while thesecond claw portion 17 is abutting against the edge of theopening portion 8 b of the capmain body 8, after the tip end side of the lockingmember 18 rotates toward the front, thesecond claw portion 17 becomes locked with the secondtarget locking portion 25 at the same time as the tip end side of the lockingmember 18 reverts to the original rearward position thereof. - By this, a state in which the
spout formation member 13 is mounted on theopening portion 8 b of the capmain body 8 is attained. In addition, a state in which thedrinking spout portion 13 e projects outward (upward) from theopening portion 8 b of the capmain body 8 at the same time as thespout formation member 13 is mounted is attained. - Meanwhile, in the
spout detachment mechanism 15, a locked state of thesecond claw portion 17 with respect to the secondtarget locking portion 25 is released by manipulation that rotates the tip end side of the lockingmember 18 forward. By this, it is possible to disengage thespout formation member 13 from the lower side of theopening portion 8 b of the capmain body 8 while the locked state of thefirst claw portion 16 with respect to the firsttarget locking portion 24 is released. - As shown in
FIG. 1 , the capmain body 8 to which thespout formation member 13 is mounted blocks theupper opening 2 d of the containermain body 2 in a state in which thespout formation member 13 is fitted into the inner side of theupper opening 2 d by being attached to the neck portion 2 c of the containermain body 2. - As shown in
FIGS. 1 to 6 , water stop packing 26 may be attached to the lowerside flange portion 13 c of thespout formation member 13 in a detachable manner. The water stop packing 26 is ring form sealing member for sealing the space between the stepped portion 7 (the container main body 2) and the spout formation member 13 (the cap main body 8). For example, the water stop packing 26 is made of an elastic member such as a rubber or an elastomer having a heat resistant property such as a silicone rubber. The water stop packing 26 is fitted to the outer peripheral portion of the lowerside flange portion 13 c. - When the water stop packing 26 is fitted into the inner side of the
upper opening 2 d of the containermain body 2, a state in which the water stop packing 26 becomes adhered to the steppedportion 7 of the containermain body 2 while being elastically deformed is attained. By this, it is possible to seal the space between the steppedportion 7 and thespout formation member 13. - As shown in
FIGS. 2 to 7 , thelid 9 opens and closes the drinking spout or the pouring spout (the liquid flow spout 14) that thespout formation member 13 forms, and for example, may be made of a heat resistant resin such as polypropylene (PP). The illustratedlid 9 includes aperipheral wall portion 9 a, which is formed in a substantially cylindrical form so as to be continuous with theperipheral wall portion 8 a of the capmain body 8, atop wall portion 9 b that covers a top surface of theperipheral wall portion 9 a, and a substantially cylindricalinner wall portion 9 c that falls away from the lower surface of thetop wall portion 9 b. - The
lid 9 is biased toward a direction in which theliquid flow spout 14 of thespout formation member 13 is opened (hereinafter, referred to as an opening direction) by a first biasingmember 27, such as a torsion spring or other biasing member) which is provided on the inner side of thehinge portion 10, which will be mentioned later. - Lid packing 28, which blocks the
liquid flow spout 14 of thespout formation member 13, is provided on the inner side of thelid 9. The lid packing 28 is a stopper form sealing member for sealing thespout formation member 13 when thelid 9 is in a closed state. - The lid packing 28 is made of an elastic member, and it is possible to use the same material as that of the above-mentioned water stop packing 26.
- As shown in
FIGS. 2 to 6 , the lid packing 28 may be a bottomed cylindrical sealing member that is attached to theinner wall portion 9 c of thelid 9 in a detachable manner. More specifically, the lid packing 28 is attached to the lower end side of theinner wall portion 9 c in a detachable manner in a state in which theinner wall portion 9 c is fitted into acentral hole 28 a on the inner side of the lid packing 28. In addition, abottom surface 28 b of the lid packing 28 is formed in drum form. Also, a steppedportion 28 c is provided in the outer peripheral portion of the upper portion side of the lid packing 28. - The lid packing 28 is attached to the
lid 9 in a detachable manner by tightly fitting theinner wall portion 9 c into the inner side of thecentral hole 28 a. By this, in thecap unit 3, even if the inside of the containermain body 2 has a negative pressure and a force in a direction of pulling the lid packing 28 is generated, it is possible to prevent a circumstance in which the lid packing 28 becomes separated from theinner wall portion 9 c when thelid 9 is opened. Conversely, even if the inside of the containermain body 2 has a positive pressure and a force in a direction of pushing the lid packing 28 is generated, it is possible to prevent a circumstance in which theinner wall portion 9 c is penetrates further onto the inner side of the lid packing 28 by the steppedportion 28 c of the lid packing 28 abutting against the base end portion of theinner wall portion 9 c. - In the
cap unit 3, when thelid 9 blocks the upper portion of the capmain body 8, a state of being adhered to the periphery of theliquid flow spout 14 while the lid packing 28 becomes elastically deformed is attained. By this, it is possible to block theliquid flow spout 14 of thespout formation member 13. - As shown in
FIGS. 1 to 7 , acover member 29, which covers the upper end side of theinner wall portion 9 c, is attached to the upper surface side of thetop wall portion 9 b in a detachable manner. Thecover member 29 is formed in a substantially disk-like form using the same material as that of thelid 9. Meanwhile, aconcave portion 30, which corresponds to thecover member 29, is provided on the upper surface of thetop wall portion 9 b. - A
cover detachment mechanism 31 for attaching thecover member 29 to theconcave portion 30 in a detachable manner is provided between thetop wall portion 9 b and thecover member 29. Thecover detachment mechanism 31 includes athird claw portion 32 on the front side of thecover member 29, and astopper 34, in which afourth claw portion 33 is provided, on the rear side of thecover member 29. - The
third claw portion 32 is positioned in the lower end portion on the front side of thecover member 29, and is provided projecting further than the tip end of thecover member 29. Thestopper 34 is provided projecting downward from the rear side of thecover member 29. Thefourth claw portion 33 is provided on the tip end of thestopper 34 projecting forward. - The
cover detachment mechanism 31 includes a thirdtarget locking portion 35 on the front side of theconcave portion 30, and a fourthtarget locking portion 36 on the rear side of theconcave portion 30. The thirdtarget locking portion 35 and the fourthtarget locking portion 36 are composed of hole portions that are respectively provided in front and rear positions of the bottom surface of theconcave portion 30. In addition, atarget locking portion 9 d protruding backwardly is formed on the base end of theinner wall portion 9 c. - In the
cover detachment mechanism 31, thecover member 29 is fitted into the inner side of theconcave portion 30 in a state in which thethird claw portion 32 is inserted into the third target locking portion (hole portion) 35. At this time, thefourth claw portion 33 is locked with thetarget locking portion 9 d in a state in which thestopper 34 is inserted into the fourth target locking portion (hole portion) 36. - By this, a state in which the
cover member 29 is mounted on the inner side of theconcave portion 30 is attained. In addition, thecover member 29 covers the upper end side of theinner wall portion 9 c at the same time as thecover member 29 is mounted. - Meanwhile, in the
cover detachment mechanism 31, a locked state of thefourth claw portion 33 and the fourthtarget locking portion 36 is release by pushing thefourth claw portion 33, which is provided on thestopper 34, upward inside thelid 9, that is, by pushing thefourth claw portion 33 from the lower side to upper side inFIG. 2 or 3 . By this, it is possible to disengage thecover member 29 from theconcave portion 30 while the locked state of thethird claw portion 32 with respect to the thirdtarget locking portion 35 is released. In addition, since thecover detachment mechanism 31 is positioned on the outer side of theinner wall portion 9 c, it is possible to visually recognize the fact that theinner wall portion 9 c passes through the up-down direction by disengaging thecover member 29. - In this manner, the
cover member 29 has a structure that is separated by being pushed in a separation direction from the inner surface of thelid 9. Accordingly, in a state in which thelid 9 of thecap unit 3 is closed, it is not possible to disengage (or minimal likelihood to disengage) thecover member 29. In addition, since thestopper 34 is disposed on the outer side of theinner wall portion 9 c, it is not necessary to disengage the lid packing 28 when thecover member 29 is disengaged. - Additionally, the
cover member 29 is not limited to a component made of the same material as thelid 9, and a component having a different material or color, or the like, may also be used, or a component made of a transparent material may also be used. In this case, it is possible to configure acap unit 3 having excellent, efficient design. In addition, by a three-dimensional structure being disposed, engraved, or the like, on the upper portion of thecover member 29, it is possible to customize thecap unit 3 and beverage container 1 including thecap unit 3 to match the preferences of a user. - In addition, the
cap unit 3 is not limited to the above-mentioned configuration in which thecover member 29 is set to be detachable from thelid 9, and it is also possible to provide a grip such as a handle on thecover member 29 by setting a configuration in which a fitting amount of thecover member 29 is adjusted to be snug, or setting a configuration in which thecover member 29 is fixed to thelid 9 using an adhesive, or the like. - The
cap unit 3 is provided with alid locking mechanism 37 that fixes thelid 9 to the containermain body 2 resisting the biasing of thetorsion spring 27 in a position (hereinafter, referred to as a blocking position) at which thelid 9 blocks theliquid flow spout 14. - More specifically, as shown in
FIGS. 1 to 6 , thelid locking mechanism 37 includes a lockingmember 39 that is attached to the capmain body 8 in a freely rotating manner using ahinge portion 38, and aring stopper 40 that is attached to the capmain body 8 in a freely rotating manner using thehinge portion 38. - The locking
member 39 is supported so as to be capable of freely rotating in the up-down direction by thehinge portion 38, which is provided on the front side of the cap main body 8 (theperipheral wall portion 8 a). The lockingmember 39 includes afirst arm portion 39 a that extends upward from thehinge portion 38, and asecond arm portion 39 b that extends downward from thehinge portion 38. - A
hook portion 41 is provided at the tip end of thefirst arm portion 39 a (the upper end of the locking member 39) projecting rearward. Anelastic member 42 is disposed between thesecond arm portion 39 b and theperipheral wall portion 8 a. Additionally, for example, a spring member such as a coil spring may be used in place of theelastic member 42. - The
ring stopper 40 is composed of a ring form member in which a portion is open, and both ends thereof are supported so as to be capable of freely rotating on the outer side of thehinge portion 38. By this, thering stopper 40 is capable of rotating in the up-down direction. - Meanwhile, the
lid locking mechanism 37 includes alock bearing portion 43 with which thehook portion 41 of the lockingmember 39 locks, and astopper bearing portion 44 onto which thering stopper 40 latches. Thelock bearing portion 43 is composed of a claw portion that projects forward from the lower end portion of the front side of the lid 9 (theperipheral wall portion 9 a). Thestopper bearing portion 44 is composed of a wall portion that projects forward from a position that surrounds the periphery of the lock bearing portion (the claw portion) 43 in a shape that corresponds to the inner side of thering stopper 40. - In the
lid locking mechanism 37, when thelid 9 blocks the upper portion of the capmain body 8, the state in which thelid 9 blocks the upper portion of the capmain body 8 is maintained by thehook portion 41 of the lockingmember 39 locking with thelock bearing portion 43. From the state, the locked state of thehook portion 41 with respect to thelock bearing portion 43 is released by performing pressing manipulation of thesecond arm portion 39 b side of the lockingmember 39 while elastically deforming theelastic member 42. By this, it is possible to rotate thelid 9 in the opening direction by the biasing of thetorsion spring 27 inside thehinge portion 10. - Meanwhile, in the
lid locking mechanism 37, when thelid 9 blocks the upper portion of the capmain body 8, rotation of thelid 9 in the opening direction is prevented by thering stopper 40 latching onto thestopper bearing portion 44. By this, in thelid locking mechanism 37, it is possible to prevent or at least minimize a circumstance in which thelid 9 opens by unintentional manipulation of the lockingmember 39. - Incidentally, the
cap unit 3 has a compact hinge structure having excellent, efficient design properties by consolidating functions in thehinge portion 10. More specifically, as shown inFIGS. 7, 10, 11 and 13 , thehinge portion 10 includes the firsthinge bearing portion 45, which is provided on the capmain body 8, the secondhinge bearing portion 46 and the thirdhinge bearing portion 47, which are provided on thelid 9, and ahinge shaft 48 attached in a state of passing through the first, second, and thirdhinge bearing portions hinge bearing portion 45 is positioned between the secondhinge bearing portion 46 and the thirdhinge bearing portion 47. - As shown in
FIGS. 10 and 13 , the firsthinge bearing portion 45 is formed in a substantially cylindrical form including a shaft opening 45 a that passes therethrough in a rotating shaft direction, and is provided projecting from a rear side central portion of the capmain body 8. In addition, a first storageconcave portion 45 b, in which a surface side that faces the secondhinge bearing portion 46 is recessed in a substantially cylindrical form in the rotating shaft direction, is provided in the firsthinge bearing portion 45. In addition, a firstarm bearing portion 45 c, in which a surface side that faces the secondhinge bearing portion 46 is recessed to correspond to the shape of a first end side of thetorsion spring 27, is provided in the firsthinge bearing portion 45. - As shown in
FIGS. 7 and 12 , the secondhinge bearing portion 46 is provided projecting from one side of the rear side central portion of thelid 9 so as to have a shape that is continuous with the firsthinge bearing portion 45 including a shaft opening 46 a that passes therethrough in the rotating shaft direction. The secondhinge bearing portion 46 includes a first facing surface member (the other facing surface member) 49 that configures a surface that faces the firsthinge bearing portion 45. - The first facing
surface member 49 is attached in a state of being fitted into the inner side of a first fitting concave portion (the other fitting concave portion) 46 b, which is provided in the secondhinge bearing portion 46. A component made of a material that differs from that of the secondhinge bearing portion 46, for example, component (a POM in the present embodiment) made of a material having superior wear resistance to the secondhinge bearing portion 46, such as a polyacetal (POM), an acrylonitrile butadiene styrene (ABS), a metal, or any other suitable material known in the art, is used in the first facingsurface member 49. - In the
cap unit 3 of the present embodiment, by configuring the first facingsurface member 49 having excellent wear resistance as a separate body to that of the secondhinge bearing portion 46, it is possible to achieve an improvement in the durability of thehinge portion 10. Additionally, the secondhinge bearing portion 46 is not necessarily limited to a component in which the first facingsurface member 49 is configured as a separate body, and a configuration in which the first facingsurface member 49 is set to be integral may also be used. - Among the surfaces of the first facing
surface member 49, a plurality (four in the present embodiment) of projectingportions 50, which come into sliding contact with the firsthinge bearing portion 45, are provided on a surface (a first surface) that faces the firsthinge bearing portion 45. In addition, among surfaces of the first facingsurface member 49, a secondarm bearing portion 49 a, which is recessed to correspond to the shape of the second end side of thetorsion spring 27, is provided on a surface that faces the firsthinge bearing portion 45. - The plurality of projecting
portions 50 are provided projecting in a substantially hemispherical form in order to decrease friction resistance when coming into sliding contact with the firsthinge bearing portion 45. In addition, the plurality of projectingportions 50 are provided aligned in a radial manner (possibly at equally spaced intervals) at the periphery of the shaft opening 45 a, which is configured by the first facingsurface member 49. Additionally, regarding the number of the projectingportions 50, certain embodiments include at least three protectingportions 50. - Meanwhile, as shown in
FIGS. 10 and 13 , among the surfaces of the firsthinge bearing portion 45, a slidingcontact surface 45 d, which comes into sliding contact with the plurality of projectingportions 50, is provided on a surface (a second surface) that faces the first facingsurface member 49. The slidingcontact surface 45 d is formed in a substantially toric form at the periphery of the first storageconcave portion 45 b and the firstarm bearing portion 45 c. - The
torsion spring 27 is disposed on the inner side of the firsthinge bearing portion 45.
