Coupling unit has the spinning force that the outside is applied on the switching accessory and is communicated to directly or indirectly on the screw top to give the function of screw top spinning force.Described coupling unit can be coupled on the mounting structure that is assemblied on the screw top, rotates with consistent with screw top.Therefore, the assembled formation of coupling unit mounting structure, it can consistently with screw top rotate.Perhaps, coupling unit can directly be formed on the correct position of screw top outside face.
Screw top opens and closes accessory machinery and forms situation with the screw top independent entity, and described mounting structure has makes the coupling unit can be by consistent function of rotating with screw top.Described mounting structure is placed between screw top and the coupling unit.Described mounting structure can form and the screw top independent entity, and is assembled in and is used for rotate consistent with it on the screw top.
Described mounting structure comprises: annular element, its a part or whole part ground is around the external peripheral surface of the tubular foundation parts of screw top.The inner circumferential surface of described annular element has the abutment joint of external peripheral surface of the tubular foundation parts of butt joint screw top.Described abutment joint preferably includes pressure-producing part, and it is to the side of the center of shut-off block pushing shut-off block, with the tubular foundation upper parts of components of pushing screw top, i.e. the side surface position of shut-off block.The height of described annular element preferably is set to approximate the height of screw top, to improve the stability of confined state.
In this mode, abutment joint is formed on the inner circumferential surface of annular element, so that the part of abutment joint can be used as the pressure-producing part operation.Mounting structure is assemblied on the screw top tightly, and pressurized parts keep.Thus, mounting structure can consistently with screw top be rotated, and can not make relative screw top idle running of mounting structure or mounting structure clamp the tubular foundation parts of screw top.If have only pressure-producing part that the additivity of assembly unit to screw top is set, described state is with instability, and mounting structure tends to come off from screw top.But the tubular foundation parts of described abutment joint butt joint screw top are to the height of the tubular foundation parts of about screw top, thereby the additivity of mounting structure to screw top stablized in permission.
Though mounting structure can be made of with the screw top materials similar a kind of, it also can be made of different materials.That is, can suitably select to use repeated use effectively, firm or cheap material.Be formed thin circular cylinder if possess the annular element of mounting structure, annular element can be unheavy, can reduce quantity of material simultaneously.But annular element also can be that heavy wall maybe can be the shape different with drum.Mounting structure can provide the upper plate on the annular element top, with the end along cylindrical direction closed ring parts.In this case, mounting structure can be made of transparent material, to avoid can't see from the outside the letter that is provided on the screw top shut-off block upper surface or the printed article of picture format class.
Open and close accessory, amplify spinning force, and the strength of described amplification is conveyed to screw top by coupling unit from external action.Thereby, may need the switching of the screw top of big strength originally, can carry out with less strength.Described switching accessory, an end is connected to coupling unit, and the other end is a free end.When opening and closing that accessory is in unused state still and during the state that was not opened as yet, its be placed on screw top outside face or mounting structure near.When being opened or be closed, opening and closing accessory and be removed, so that its free end is away from the outside face of screw top or mounting structure.In this manner, in the consistent time period of rotating with swivelling cover, the moving-member of larger diameter is createed, and it increases the radius of rotation that opens and closes accessory.
When accessory machinery was not used or current when just not being used as yet, open and close accessory and be positioned near the just enough of screw top outside face or mounting structure.Described switching accessory, it is parallel or angled to be placed as relative screw top shut-off block.Opening and closing in the time period, open and close the accessory free end side, can in perpendicular, be reversed, thereby be separated from annular element or assembly unit.Yet, preferably, open and close accessory, place along the external peripheral surface of the annular element of mounting structure, or place along the external peripheral surface of the tubular foundation parts of screw top.When opening and closing, open and close accessory, with the coupling unit centre of gration rotation, its free end is in horizontal plane, be moved on the external peripheral surface direction away from the annular element of tubular foundation parts thus.It should be noted that the cylindrical direction of the tubular foundation parts of screw top, parallel with vertical direction.
Be more preferably, described switching accessory is that the belt of width is formed by the height number with screw top tubular foundation parts.Described belt is bent, and has round circular shape.By doing like this, described switching accessory can be unheavy, and therefore only need small quantity of material.When opening and closing, the wide cut surface of the switching accessory that extends along the height that opens and closes accessory is used as the lever pulling, gives the screw top spinning force.Opening and closing auxiliaring effect can stably realize, and don't injury user's hand or finger.
The rotation stop member is formed, and is used for outwards protruding from the proximal outside face of the switching accessory that is connected to coupling unit.Preferably, described rotation stop member is formed like this, is that the center rotates when annular element is removed with the coupling unit when opening and closing accessory promptly, and the rotation that opens and closes accessory will be stopped at default angle.
Certainly, the structure of switching accessory is not limited to above-mentioned situation.For example, open and close accessory, can form ring-type.Container can be arrested or be tangled with the finger, hook or the cord that are placed on the user in the ring.
Example 1
Now with reference to accompanying drawing (Fig. 1 to 4) several examples that screw top according to the present invention opens and closes accessory machinery 10 are described.The screw top that it should be noted that this example 1 opens and closes accessory machinery 10, be as with screw top 20 type that forms of member independently.That is, in use, screw top opens and closes accessory machinery 10 and is assembled on the screw top 20, is used for rotating with consistent with it, as shown in Figure 1.
For example, container 30 is PET (the polyethylene terephthalate: polyethylene terephthalate glycol) bottle that hold beverage.This container forms by blowing casting lucite such as polyethylene terephthalate glycol, and to form the tubular foundation parts that the bottom comes down to cylinder, its top narrows down so that opening features 31 to be provided.The excircle parts of described opening features 31 are by constituting as the open circuited screw-shaped screw thread that is subjected to screw member 32 operations.Screw top 20 can screw togather by being subjected to screw member 32 and opening 31, shown in Fig. 2 A, to allow the switching that repeats of opening 31.
Screw top 20, by be essentially columned basic components 21, close tubulose basic components 21 upper ends disc-shaped part 22, keep and to make with evidence ring 23.Described tubular foundation parts 21, disc-shaped part 22, reservation have been cast as mutually by polypropylene with evidence ring 23 to become one.Described reservation is with evidence ring 23, is coupled between on the point of a plurality of point-like on the lower end of tubular foundation parts 21.Be made of polypropylene material though it should be noted that the screw top 20 here, it also can be made by other any appropriate plastic material, as polyethylene.
The inner circumferential surface of tubular foundation parts 21, by as be subjected to screw member 24 operation, open circuited spiral thread constitutes.When closing, the low surface of shut-off block 24 is along with hermetically closing parts 25 are formed by the inner circumferential surface placement along opening features 31, to improve the hermetically closing performance.In this example, these hermetically closing parts 25 are cast into screw top 20 and become one, and still, the hermetically closing parts also can be the members that independently forms with container.It should be noted that the tubular foundation parts 21 of described screw top 20 come down to very near columned tubbiness because the what is called that casting synthetic resin brings is cast or thermal deformation.That is, tubular foundation parts 21 are made into such shape, and its upper end vicinity diameter diminishes, and the intermediate portion expands highly a little along it, and its tubulose mildly diminishes to lower end diameter from the centre part.
The reservation of polypropylene material system is with evidence ring 23, and the tubular foundation parts 21 that are cast into polypropylene material system become one.But, be not to become one with keeping to be cast into mutually with evidence ring and tubular foundation parts.That is, also can adopt the not dual manufacturing shaping of same material, and not pass through inblock cast.Keeping with evidence ring 23, might not be necessary, also can exempt.But the unauthorized of the screw top machinery of preferably witnessing is opened or is guaranteed as yet the not mode of usability.Keep with evidence ring 23, keep by annular and make with evidence ring main body 26 and a plurality of sheets 27 that prevent to be shifted.Annular keeps with ring of evidence ring main body formation, the diameter of the inner circumferential surface lower end of its big or small corresponding screw top 20.The sheet 27 that prevents to be shifted becomes one with the bottom that keeps with the inner circumferential surface of evidence ring main body 26, and in case is mounted and just is difficult for being disassembled.But it is restriction not, and any suitable being used to prevents that the technology that is shifted all can be used.
The screw top of this example opens and closes accessory 10 to be made up of hard polyethylene, and join for screw top 20 member independently.With reference to Fig. 2 A and 3C, described screw top opens and closes accessory machinery 10 and comprises: annular element 11, and it surrounds the external peripheral surface of the cylindric tubulose basic components 21 of screw top 20; With assembling stop member 12, the upper end of itself and annular element 11 becomes one.Described screw top opens and closes accessory machinery and also comprises: coupling unit 13, and its external peripheral surface with annular element 11 forms one, brings into play the effect of hinge; With switching accessory 14, itself and coupling unit 13 become one.Described screw top opens and closes accessory machinery and further comprises: rotation stop member 15, it becomes one with switching accessory 14.Certainly, the material that screw top opens and closes accessory machinery 10 is not limited to hard polyethylene, and any suitable themoplasticity synthetic resin all can use as polypropylene or polyamide or metal.It should be noted that annular element 11 requires the conformability of shape stability or flexible in size, coupling unit 13 will have the characteristic of the alternating bending of bearing simultaneously, and opens and closes the shape stability that accessory 14 will possess toughness and so on too.Therefore, need to select to satisfy the material of these requirements.
Annular element 11 comes down to cylindric, and has the height of the tubular foundation parts 21 that approximate screw top 20 greatly.The interior diameter of annular element is set to approximate greatly the overall diameter of the tubular foundation parts 21 of screw top 20.It should be noted that because the overall diameter of the tubular foundation parts 21 of screw top 20 is non-constant therefore, the interior diameter of annular element 11 is set to approximate greatly or less times greater than the mean outside diameter of tubular foundation parts 21.That is, annular element 11 is configured to, dock as the external peripheral surface of abutment joint 16 with the inner circumferential surface of annular element 11 with the tubular foundation parts 21 of screw top 20, and don't the external peripheral surface of pushing screw top 20, shown in Fig. 2 B.It should be noted that dual foundry engieering can be used for making abutment joint 16, thus, the inner circumferential surface of the annular element of being made by hard themoplasticity synthetic resin 11 can be formed by hard material and soft material, can be used for soft material as elastomeric material or rubber.Do like this, can prevent the idle running of annular element screw top 20.
Speak of the thickness of annular element 11, if annular element 11 is too thick, it is too hard that annular element will become, so its alerting ability can reduce, and its size identical property is worsened.On the other hand, if annular element 11 is too thin, annular element will lack intensity and support switching accessory 14.Therefore, the thickness of annular element 11 should be set at suitable value according to properties of materials.For example, if use hard themoplasticity synthetic resin such as polyethylene, polypropylene or polyamide, it is 0.5 to 3.0 millimeter that annular element 11 preferably is set to mean thickness.
A plurality of rib-loop shape pressure-producing parts 17 are formed near the upper end of inner circumferential surface of annular element 11, extend internally with the inner circumferential surface from annular element 11.It should be noted that six pressure-producing parts 17, equidistantly be formed near the upper end of inner circumferential surface of annular element 11, as shown in Figure 3.Described pressure-producing part 17 is arranged to the top, side of discoid shut-off block 22 of pushing screw top 20, and is indicated as the arrow of Fig. 2 B.
Assembling stop member 12 is operating as when assembling screw top 20 by downward pushing screw top, prevents from screw top is opened and closed the too much pushing of accessory machinery 10.Assembling stop member 12 forms flat ring-type, in the top of annular element 11.When screw top being opened and closed accessory machinery 10 when being assembled on the screw top 20, assembling stop member 12 docks with the top surface edge of the shut-off block 22 of screw top 20.At this moment, be positioned at the letter of shut-off block 22 upsides of screw top 20 or the engraving or the printed article 28 of pattern class, can see from the outside by the circular open 18 that is provided in to assemble in the stop member 12, as shown in Figure 1.
Coupling unit 13 is operating as by the connection of hinge shape, connects annular element 11 and opens and closes accessory 14.Specifically, coupling unit 13 is hinge class parts, vertically extend from upper extreme point to the lower extreme point of the external peripheral surface of annular element 11, and an end of coupling unit is connected on the annular element 11.The other end of described coupling unit 13 is connected to and opens and closes on the accessory 14.
Opening and closing operations accessory 14 is operating as the spinning force that increases the switching screw top 20 that is used for external action, and is used for the spinning force of described enhancing is conveyed to screw top 20, as shown in Figure 3.Opening and closing operations accessory 14 is the band-like portions that reduced thickness, and the one end is connected to coupling unit 13, and the other end is operated as free end.Described opening and closing operations accessory is used as lever.The height of described band-like portions approximates annular element 11 greatly, and has selectable length.Described band-like portions are arc, near the outer circumferential sides that is placed on annular element 11, just, near the outer circumferential sides of the tubular foundation parts 21 of screw top 20.In this example, open and close the length of accessory 14, be set to half of outer perimeter of about annular element 11.But this length without limits.It should be noted that when described screw top be still not use as yet or not when being used, consider that screw top opens and closes the degree of firmness of the size of accessory machinery, the length that preferably opens and closes accessory is no more than half of outer perimeter of annular element 11.It shall yet further be noted that it needs higher intensity if open and close in the accessory use oversizely, still, if it is too short to open and close accessory, required switching strength can't be enhanced.Therefore, need to consider the variable of foregoing description, being provided with and opening and closing accessory 14 is suitable length.
When opening and closing still use as yet of accessory machinery 10, do not used or being in closed condition, it is placed near the external peripheral surface of annular element 11, as shown in Figure 3A.When opening and closing accessory 14 when being in open mode, the free end that opens and closes accessory with coupling unit 13 as centre of gration by left-hand revolution, shown in Fig. 3 B.Therefore, opening and closing accessory 14 is removed from the external peripheral surface of annular element 11.
With reference to Fig. 4 A that the closed condition that opens and closes accessory is shown, suppose distance from the centre of gration O of screw top 20 to the root P1 of coupling unit 13, just the outside radius of annular element 11 is r.In addition, supposing from root P1, is d to the distance of extending to the outside radius shape from root P1, rotate the forefront spare P2 of stop member 15; And, only suppose that promptly the external peripheral surface right-hand revolution screw top 20 needed strength of annular element 11 are f.Only firmly grasp the external peripheral surface of annular element 11, realize the moment that needs strength of screw top 20 clickwises, be expressed as f * r simply.If, promptly rotate now the forefront spare P2 of stop member 15, with identical strength f clickwise screw top 20, the moment of current strength can be expressed as n=f * (r+d)=f * r+f+d.Therefore, the moment of described strength will be than big f+d during annular element 11 rotating screws lid promptly only.
Therefore, be g if only firmly grasp the lower limit strength of the annular element 11 clickwise screw tops 20 of screw top, so, only promptly rotate the lower limit strength of the forefront spare P2 clickwise screw top 20 of stop member 15, can be represented as gr/ (r+d).Therefore, can with only promptly during annular element 11 clickwises (1+d/r)/one's of required strength strength the screw top clickwise just is set to off position with it.
On the contrary, in opening operation, open and close accessory 14 with coupling unit 13 as the centre of gration left-hand revolution, up to 15 pairs of external peripheral surfaces that connect annular element 11 of rotation stop member.The free end that described operation will open and close accessory 14 separates from screw top, shown in Fig. 4 B.Open and close the free end of accessory, be positioned at the some P3 on the extended line of line of root P1 of the center O of connecting bolt lid 20 and coupling unit 13, create thus one can consistently with screw top 20 rotate than the major diameter moving-member.At this moment, approximate 3r apart from r ', because distance, approximate the diameter of annular element 11 from the end P1 that opens and closes accessory 14 to a P3 from center O to a P3.
Therefore, be F if only firmly grasp annular element 11 left-hand revolution screw tops 20 required spinning forces, the moment of so described strength can be expressed as N=F * r.If promptly open and close the forefront spare P3 of accessory 14, with same big strength F left-hand revolution screw top 20, the moment of so described strength can be expressed as F * 3r=3N.That is, in this case, screw top 20 can be when only equaling that promptly annular element 11 rotating screws cover 20 situations, and 1/3rd strength is opened.
In fact, open required spinning force, especially for what break a seal, the strength that needs is bigger than closing.By above-described screw top is opened and closed the arrangement of accessory machinery 10, the strong point of the structure by described switching accessory 14 can obtain bigger moment when opening operation.In this example, screw top 20 and screw top switching accessory machinery 10 is made up of the entity that differs from one another.Certainly, coupling unit 13 can become one with the external peripheral surface of the tubular foundation parts 21 of screw top 20, and described switching accessory 14 can after be connected to the other end of coupling unit 13.By doing like this, screw top opens and closes accessory machinery 10 can not be subjected to the interference of annular element 11, and is associated on the screw top 20.
Example 2
Example 2 of the present invention opens and closes the distortion of accessory machinery as screw top according to the present invention, will be below with reference to the accompanying drawings (Fig. 5 and Fig. 6) be elaborated.In the following description, the explanation with the similar structures of example 1 will be omitted.To open and close accessory machinery similar to the screw top of example 1, and screw top opens and closes accessory machinery 110 and forms from screw top 120 member independently.
With reference to Fig. 5 and Fig. 6, the screw top that the polypropylene of this example is formed opens and closes accessory machinery 110 and comprises: annular element 111, and it surrounds the external peripheral surface of the tubular foundation parts 21 of screw top 20; With discoid assembling stop member 112, the upper end of itself and annular element 111 becomes one.Described screw top opens and closes accessory machinery and also comprises: coupling unit 113,113, and its external peripheral surface with annular element 111 forms one, to bring into play the effect of hinge; With switching accessory 114,114, itself and coupling unit 113,113 become one.Screw top opens and closes accessory machinery and further comprises: rotation stop member 115,115, it becomes one with switching accessory 114,114.
Described annular element 111 for cylindric in fact, and highly approximates the height of the tubular foundation parts 21 of screw top 20.The interior diameter of described annular element is set to approximate greatly the overall diameter of the tubular foundation parts 21 of screw top 20.It should be noted that because the overall diameter of the tubular foundation parts 21 of screw top 20 is non-constant, so the interior diameter of annular element 111 is set to approximate greatly or less times greater than the mean outside diameter of the tubular foundation parts 21 of screw top 20.That is, annular element 111 is configured to, and is abutment joint with the inner circumferential surface of unshowned annular element 111, the external peripheral surface of the tubular foundation parts 21 of butt joint screw top 20, and can not push the external peripheral surface of screw top 20.Unshowned a plurality of rib-loop shape pressure-producing part, be formed at annular element 111 inner circumferential surface the upper end near, extend internally with inner circumferential surface from annular element 111.It should be noted that six pressure-producing parts, equidistantly be formed near the upper end of inner circumferential surface of annular element 111.These pressure-producing parts are arranged to the side to the shut-off block 22 of center pushing screw top 20.
Described assembling stop member 112 is operating as and during fit on screw top 20, is preventing from screw top is opened and closed the too much pushing of accessory machinery 110 by downward pushing screw top.Described assembling stop member 112 for discoid in fact, is formed on the top of annular element, is used for SealingThe whole in fact zone on the top of annular element 111.When screw top being opened and closed accessory machinery 110 when being assembled on the screw top 20, the lower curtate of assembling stop member 112 docks with the upper surface of the shut-off block 22 of screw top 20 in fact.
Described coupling unit 113,113 is operating as by the connection of hinge shape, connects annular element 111 and opens and closes accessory 114,114.Specifically, coupling unit, provide with the hinge class part of annular element 111 antipodal positions, vertically extend to the lower end from the upper end of the external peripheral surface of annular element 111.One end of coupling unit 113,113 is connected to annular element 111, and its other end is connected to switching accessory 114,114.
Described switching accessory 114,114 is operating as what lever increased that the outside applies and opens and closes spinning force on the screw top 20, and is used for the spinning force of described increase is conveyed to screw top 20.Opening and closing accessory 114,114, is the band-like portions that reduce thickness, and the one end is connected to coupling unit 113,113, and the other end is a free end.These band-like portions highly approximate annular element 111, and have selectable length.These band-like portions are arc, near the outer circumferential sides that is placed on annular element 111.In this example, open and close the length of accessory 114,114, be set to 1/4th of about annular element 111 outer perimeters.
When opening and closing that accessory machinery 110 does not still use as yet or currently not when being used or be in closed condition, opening and closing accessory 114,114, be placed on annular element 111 external peripheral surface near, shown in Fig. 5 A.When the switching accessory was in closed condition, the free end that opens and closes accessory was the centre of gration left-hand revolution with coupling unit 113,113, shown in Fig. 5 B.Therefore described switching accessory is removed from the external peripheral surface of annular element 111.
Simultaneously, in shutoff operation, the outside radius r0 of annular element 111 and forefront spare from the center O of screw top 20 to each rotation stop member 115,115 apart from r1, r1 and r0 are set to r1>r0, as shown in Figure 6A.Therefore, compared with the external peripheral surface clickwise screw top of only firmly grasping annular element 111, screw top can be more easily by clickwise.
On the contrary, in opening operation, described switching accessory 114,114 is that centre of gration is by left-hand revolution, up to rotating the rotation stop member 115,115 that 115,115 pairs of stop members connect annular element 111, shown in Fig. 6 B with coupling unit 113,113.The free end that this operation will open and close accessory 114,114 separates from screw top, shown in Fig. 6 B.The free end of switch accessory 114,114 is positioned at from the center O of screw top 20 on the extended line of the line that the root of coupling unit 113,113 prolongs, thus, create one can consistently with screw top 20 rotate than the major diameter moving-member.
If during this time, be set to r2>r1>r0 from center O to the distance that opens and closes accessory 114,114, the external peripheral surface left-hand revolution screw top 20 compared with only firmly grasping annular element 111 can more easily rotate described screw top.
In essence, open needed rotational force, when particularly breaking a seal, need be than closing bigger strength.In the described arrangement,, can in opening operation, obtain bigger moment in the above owing to open and close the configuration of accessory 114,114 to screw top switching accessory machinery 110.Though its processing may be more complicated than only using a switching accessory 14, it can gain in strength or spin intensity.Certainly, can provide three or more switching accessories.In this example, screw top 20 and screw top open and close accessory machinery 110, form the entity that differs from one another.But coupling unit 113 can form one with the external peripheral surface of the tubular foundation parts 21 of screw top 20, and open and close accessory 14, can be connected to the other end of coupling unit 113.By doing like this, screw top opens and closes accessory machinery 10, not be associated on the screw top 20 by the intervention of annular element 11.
Example 3
Example 3 of the present invention, as the distortion that screw top according to the present invention closes accessory machinery 210, inciting somebody to action below with reference to the accompanying drawings, (Fig. 7 to Fig. 9) is described in detail.In the following description, the explanation with the similar structures of example 1 and example 2 will be omitted.In this example, screw top opens and closes accessory machinery 210 and is cast into the type that opens and closes accessory machinery formation one with screw top.
Shown in Fig. 7 A and 7B, the screw top that is formed by polypropylene of this example opens and closes accessory 210, in outside and its formation one of screw top 20.Described screw top 220 comprises: tubular foundation parts 221, and it is essentially cylindric; Be essentially discoid shut-off block 222, the upper end of its closed tube basic components 221.The inner circumferential surface of tubular foundation parts 221 is formed by non-open spiral shape, the screw thread that is operating as screw member.Be used to improve the hermetically closing parts 225 of hermetically closing characteristic, be provided in the lower surface of tubular foundation parts 221.Partial groove parts 211 along the whole edge of the upper surface of shut-off block 222, form with the form of the lowercase R of upset.The switching accessory 214 of ring-type is assemblied in the partial groove parts 211 movably.
Described switching accessory 214 is provided in the top of screw top 220 by coupling unit 213.Described coupling unit 213 is hinge class parts, the partial groove parts 211 that the one end is joined to screw top 220 bottom, an other end is joined to and opens and closes accessory 214.Described switching accessory 214 has round section, the circular ring-type of its whole formation.The forefront spare of coupling unit 213 is associated to an end of described ring-type.
When screw top opens and closes that accessory machinery 210 does not still use as yet or current not when being used, open and close accessory 214 and be assembled in the partial groove parts 211 of screw top 220, therefore, its be placed on screw top 220 near, as shown in Figure 7.In opening and closing operations, described switching accessory 214 is lifted from partial groove parts 211, and is that S. A. is rotated about 180 ° with coupling unit 213 in perpendicular, thereby is removed from screw top 220, as shown in Figure 8.
Described annular opens and closes the interior diameter of accessory 214, approximates the interior diameter of the partial groove parts 211 that extend to form at the whole edge of shut-off block 222 greatly.Open and close the overall diameter φ 1 of accessory 214, be set to approximate greatly the overall diameter D of the tubular foundation parts 211 of screw top 220.Therefore, with the coupling unit centre of gration when being lifted 180 ° when opening and closing accessory 214, to the distance at the center of shut-off block 222, approximate the overall diameter D of tubular foundation parts 211 from the center of the described switching accessory 214 that is rotated.The radius of rotation of screw top 220 increases the corresponding number that opens and closes the overall diameter φ 1 of accessory 214, therefore, create consistent with swivelling cover 220 reverse than the major diameter part.
Form ring-type owing to open and close accessory 214, user's finger can be placed on annular and open and close in the accessory 214.Therefore, the user can be placed on his or her finger and carry container in the ring or open and close screw top 220.
In the superincumbent explanation, described partial groove parts 211 form along the top edge of closing working part 222.But described partial groove parts 211 must not form along the top of closing working part 222.For example, partial groove parts 211 can form, and an end of partial groove parts 211 is at the upper limb of shut-off block 222a or 222b, and its other end is in the lower end of tubular foundation parts 221a or 221b, be positioned at the complete opposite location of that end of partial groove parts above-mentioned, example as shown in Figure 9.In this case, partial groove parts 211a or 211b tilt from the upper part to antipodal end portion, and its upper part of removing is formed among tubular foundation parts 221a or the 221b.
