The flow export 21 that is positioned at outflow portion main body 20 tops forms cylindrical shape, is formed with screw-shaped external screw thread 21a on its outer peripheral face.This external screw thread 21a be formed at the negative thread 15 that cover on 2 the internal face and mesh and make and cover 2 and be screwed on this flow export 21.Like this, lid 2 loading and unloading are installed on this flow export 21 freely.
In addition, be formed with a pair of block of giving prominence to foreign side from the outer peripheral face of flow export 21 25,25 in the bottom of flow export 21.Each block 25,25 is fan shape, and its outward flange is and has the circular-arc of regulation curvature.The outward flange of each block 25,25 forms in the mode that is positioned at the outer peripheral inboard of pedestal 23a.Block 25,25 with the front face of container B and back side portion opposite position on both separate, both end faces are parallel to each other and respectively in opposite directions.Block 25,25 is configured on the top position of the pedestal 23a on upper strata predetermined distance, is formed with the gap between the pedestal 23a on block 25,25 and upper strata.Between this pedestal 23a and block 25,25 in the formed gap, the formed a plurality of ribs of mode so that pedestal 23a and block 25,25 are coupled together are set as to block 25,25 outward flanges and extend.
A pair of rib 30,30 among these ribs, with from the outer peripheral face of flow export 21 respectively to the left and right the direction mode of extending form.The front end of this rib 30,30 is outstanding to the radial direction outside from the outward flange of block 25,25.The front end of rib 30,30 that should be outstanding is to cover the ratchet 40,40 that the claw 10,10 on 2 the hoop parts 5,5 engages with being formed at.This ratchet 40,40, on the outward flange of block 25,25, on the position of symmetry that with flow export 21 is axle, with towards with unscrew cover 2 the opposite side of Kaifeng direction X slightly the bevelled mode be provided with.
In addition, a pair of rib 31,31, from the midway location between the front end of the root of above-mentioned rib 30,30, with rib 30,30 form right angles extend to the outward flange of block 25,25.The front end of rib 31,31 is also outstanding laterally from the outward flange of block 25,25.Should outstanding part also work as ratchet 41,41.It is on the position of symmetry of axle that ratchet 41,41 also is located at flow export 21.In addition, because rib 31,31 is from the root of rib 30,30 and the midway location between the front end, extend with rib 30,30 form right angle ground, so ratchet 41,41 must be to covering 2 the opposite side extension of Kaifeng direction X with unscrewing.Ratchet 40,41 becomes in the position configuration that makes progress in week: when unscrewing the lid 2 that has been tightened, ratchet 40,40 engages respectively with claw 11,11 simultaneously with claw 10,10 and ratchet 41,41.
In addition, except these ribs 30,31, between pedestal 23a and block 25,25,4 ribs extend from the outward flange of flow export 21 outer peripheral faces to block 25,25.These ribs are being unscrewed at the rib 30,30 with ratchet 40,40 and with respect to this rib 30,30 between end face 25a, the 25a that covers 2 Kaifeng direction X, and and tightening between end face 25b, the 25b that covers 2 direction Y, each forms one.Form by this way respectively about these ribs, clip flow export 21 between the front end of promptly a pair of rib 32,32 and between the front end of a pair of rib 33,33 and become symmetrical manner.
Among these ribs, be positioned at and unscrew the end face 25a that covers 2 Kaifeng direction X, the rib 32,32 of 25a one side, form from the outstanding slightly laterally mode of block 25,25 outward flanges with its front end face, in addition, and at the rib of tightening between end face 25b, the 25b that covers 2 direction Y 33,33, the mode that is positioned at from the inboard of block 25,25 outward flange predetermined distances with its front end face forms.In addition, the front end of rib 32,32 outward flange that also can be set as with block 25,25 becomes a face.The front end face of this rib 32,32 is hoop parts 5,5 to be pressed into radial direction contact with jut 12,12 when inboard, and what stop that 5,5 generations of hoop parts are out of shape prevents variant part 42,42.The position that makes progress in the week relation of the front end of this rib 32,32 is being set, cover 2 o'clock ratchets 40,41 and engage unscrewing, and to be cut off preceding position corresponding with cut off machine 6,6 with claw 10,11.When lid was rotated to the position of cut off machine 6,6 before being cut off, jut 12,12 was positioned at and prevents variant part 42,42 position in opposite directions.
According to mouth plug device with above structure, will cover 2 and rotate and when unscrewing with respect to flow export 21, followingly work like that.
Fig. 9 represent to cover 2 twist be combined on the flow export 21, the state of flow export 21 after being sealed.As shown in Figure 9, under lid 2 airtight the states of flow export 21, connecting cut off machine 6,6 between the hoop parts 5,5, to be positioned at block 25,25 outer peripheral near the central authorities that make progress in week.In addition, a pair of ratchet 40,40 and claw 10,10 separate minimum gap and mutually in opposite directions.Equally, a pair of ratchet 41,41 and claw 11,11 also separate very little gap and mutually in opposite directions.Be formed at preventing variant part 42,42 and being formed at the jut 12,12 of hoop on the parts 5,5 of rib 32,32 front ends, also upwards form very little gap in week between the two, jut 12,12 is positioned at the rear side that covers 2 Kaifeng direction X.Therefore, owing on flow export 21, be formed with a plurality of ratchets 40,41, and be provided with the claw 10,11 that engages with these ratchets, on hand of rotation, produce the gap so can suppress to cover 2.In addition, covering 2 when twisting tightlyer, claw 10 is engaged with ratchet 41 than state shown in Figure 9.Like this, the occasion that the claw that must engage is originally engaged with ratchet on the corresponding ratchet in position that claw can be fastened on and too be screwed into, can suppress the gap effectively.
In addition, this mouthful plug device 1 is airtight under the state of flow export 21 at lid 2, makes between ratchet 40,41 and the claw 10,11 and forms the gap hardly, and this also plays a part inhibition and covers 2 gaps on hand of rotation.Therefore, under lid 2 airtight the states of flow export 21,, can easily distinguish and cover 2 and are Kaifeng states or keep air-tight state basically not under the situation of swivelling cover 2.
On this mouthful plug device 1, direction is outstanding greatlyyer to the left and right to be located at the outward flange of pedestal 23a of block 25,25 belows.And, be configured on the position of respectively binding round on the parts 5,5, prevent in variant part 42,42 and the scope between aftermost claw 11,11 that what unscrewing the forefront that covers on 2 the direction the outward flange of pedestal 23a is outstanding laterally from each hoop parts 5,5 outer peripheral face.Therefore, ratchet 40,41 and claw 10,11 are being arranged and preventing variant part 42 and the part of jut 12,13, become the state that material is entered cover 2 inner spaces between hoop parts 5,5 and pedestal 23a, ratchet 40,41 and claw 10,11 are by pedestal 23a and bind round parts 5,5 and cover.Like this, can prevent from effectively to play tricks and break a seal to covering 2 from the outside to ratchet 40,41 parts.
In addition, on this mouthful plug device 1, the claw 10,11 that is provided with a plurality of ratchets 40,41 and engages with it.Therefore, in order under not making hoop parts 5,5 and being connected the situation that the cut off machine 6,6 that binds round parts is subjected to wound, to be rotated, must play tricks simultaneously to all ratchets 40,41 and the claw that engages with ratchet 10,11 to covering 2.But it is difficulty very that these all ratchets of being covered by hoop parts 5,5 and pedestal 23a and claw are played tricks simultaneously.Therefore, be provided with a plurality of ratchets 40,41 and the claw 10,11 that engages with these ratchets also plays the mischief-making effect that prevents.
Figure 10 is that expression claw 10,11 begins to contact with ratchet 40,41, connects the figure that the cut off machine 6,6 that binds round between the parts 5,5 will be cut off the jut 12 under the preceding state and prevent the function of variant part 42.
Shown in the arrow of Figure 10, though with the position of jut 12,12 under the situation that central side is pressed into, these jut 12,12 front ends also contact with the end face that prevents variant part 42,42 respectively, prevent to bind round parts 5,5 and produce distortion.Owing to prevent to bind round parts 5,5 distortion, thereby can prevent between claw 10,11 and ratchet 40,41, to form the gap of radial direction.Therefore, if swivelling cover 2, claw 10,11 must engage with ratchet 40,41.Like this, under the situation of not cutting off cut off machine 6,6, can prevent from really to break a seal to covering 2.
Further make from state shown in Figure 10 and to cover 2 to anticlockwise direction X rotation and will cover 2 and break a seal.When covering 2 when anticlockwise direction X rotates, a pair of ratchet 40,40 engages with claw 10,10.In addition, a pair of ratchet 41,41 and claw 11,11 both also engage mutually.Make cover 2 from this state further when anticlockwise direction X rotates, claw 10,11 is hung on the ratchet 40,41.At this moment, effect has circumferential tension force on hoop 4, thereby cut off machine 6,6 is cut off.Promptly, when the claw 10,11 of hoop parts 5 engages with cooresponding ratchet 40,41 respectively, be benchmark, hinder the specialized range position rotation of the hoop parts 5,5 that are positioned at Kaifeng direction X rear side with cut off machine 6,6, on the other hand, be positioned at the specialized range position rotation of Kaifeng direction X front side.Therefore, effect has tension force and upwards separated in week on cut off machine 6,6, thereby is cut off.
Figure 11 is that expression is observed the constitution diagram that claw 10,11 hangs over the state on the ratchet 40,41 from covering 2 upsides.But for easy understanding, this Figure 11 only schematically shows and covers 2 main body 3, connecting strap 9,9 and hoop parts 5,5.As shown in Figure 11, when claw 10,11 hung on the ratchet 40,41, hoop parts 5,5 were out of shape in the mode that bloats to foreign side at the centre portion that makes progress in week.
In addition, under the effect of these members, connect in the connecting strap 7,8,9 of hoop parts 5,5 and main body 3, be formed at jut 12,13 corresponding positions on connecting strap 9,9 be not cut off, connecting hoop parts 5,5 and main body 3 respectively, on the other hand, be located at the less two pairs of connecting straps 7,8 of corresponding locational, the thickness of claw 10,11 and width and be cut off because of the effect of cutting off power.
Further make and cover 2 when anticlockwise direction X rotation, displacement arrive ratchet 41,41 positions with jut 13,13, these displacements are crossed ratchet 41,41 with jut 13,13.At this moment, ratchet 41,41 will bind round parts 5,5 and enlarge to the pushing of the radial direction outside, and on the other hand, connecting strap 9,9 stops hoop parts 5,5 to enlarge.Therefore, effect has the power of reversing on hoop parts 5,5.Further make when covering 2 rotations and displacement and jut 13,13 arrival ratchets 40,40 positions, effect has the power of reversing on hoop parts 5,5 similarly.Like this, each bind round parts 5,5, unscrewing the toe lateral displacement downwards (with reference to Figure 13) significantly of covering 2 Kaifeng direction X.Therefore, because the hoop parts 5,5 of lid 2 produce displacement, be to cover 2 by the state behind the Kaifeng so can discern easy as can.
More than, with the claw of hoop parts and be formed at flow export and the ratchet that engages with claw respectively to be provided with two pairs form be that example is illustrated, but the quantity of claw and ratchet is not limited to this so long as a plurality of.At this moment, each ratchet and claw are set as the rotation along with lid in the position relation that makes progress in week, the position relation that they engage basically simultaneously.
