Specific implementation mode

Referring to figs. 1 to Figure 12, it is a kind of can automatic-sealed Straw cap, including vessel port 1 is equipped in the vessel port 1 Suction pipe 2 and seal pallet as made of silica gel etc. elastic material, the sealing pallet is by the variant part 3 of taper and positioned at described The holding parts 4 of 3 periphery of variant part are constituted, and the variant part 3 is provided at least is discharged designated port 5 together, and the water outlet designated port 5 is located at The suction pipe 2 is within the scope of the axis projection on the variant part 3, after crimp of the variant part by suction pipe lower end, It is discharged designated port to open, be connected to the die of suction pipe.Variant part uses the structure of taper, convenient pipette, push-plate and water outlet designated port multiple Position.

The Straw cap as shown in Figures 1 to 6 that the vessel port 1, suction pipe 2 and sealing pallet are constituted can be used alone, Straw cap etc. as packaging bag, vessel port 1 can also be integrally formed with container, can also enter as shown in Fig. 7 to Figure 12, in institute Threaded connection container cover 6 in vessel port 1 is stated, the container cover 6 is provided with the sipper pore 7 stretched out for the upper end of the suction pipe 2.

It, can be in the top of the vessel port 1 or the limit of inner wall setting radial direction for Straw cap as shown in Figures 1 to 6 Position ring 13 is provided with upper limit circle 8 and lower limit circle 9, bottom and the suction of the lower limit circle in the outer wall of the suction pipe 2 The bottom of pipe is concordant, and after assembly, the spacing ring 13 prevents suction pipe from being pulled out between the upper limit circle 8 and lower limit circle 9 Going out or is pressed into container, the purpose that the bottom of the lower limit circle is concordant with the bottom of suction pipe is, since the tube wall of suction pipe is relatively thin, When being pressed downward suction pipe, the tube wall of suction pipe may pierce through the variant part of sealing pallet, the bottom of lower limit circle and the bottom of suction pipe Portion is concordant, and equivalent to increase the pipe thickness of suction pipe, the variant part of sealing pallet is pierced through when can prevent from using.

For the Straw cap as shown in Fig. 7 to Figure 12, the structure of suction pipe is constant, i.e. the outer wall of the suction pipe 2 is provided with The bottom of spacing collar 8 and lower limit circle 9, the lower limit circle 9 is concordant with the bottom of the suction pipe 2, after assembly, the upper limit Circle 8 and lower limit circle 9 are located at the both sides up and down of the container cover 6, and suction pipe is prevented to be pulled out or be pressed into container.

For the Straw cap with container cover as shown in Fig. 7 to Figure 12, sealing the first fixed form of pallet is, described Holding parts 4 are sandwiched between the container cover 6 and the end face of vessel port 1.Seal second of fixed form such as Fig. 7, Fig. 8 of pallet Shown, the top of the container cover 6 is provided with the mounting part 10 stretched into the vessel port 1, the lower end of the mounting part 10 to Flanging forms button bit ring 11, and the inner wall of the holding parts 4 is provided with the groove 12 being adapted with 11 shape of button bit ring, dress After matching, the groove 12 is sleeved on the button bit ring 11.The third fixed form for sealing pallet is as shown in Figure 9, Figure 10, institute The inner wall for stating vessel port 1 is provided with radial support portion 17, and the inside of the support portion 17 forms interconnecting piece 18, institute to upper overturning It states holding parts 4 and is provided with the fitting groove 19 that Open Side Down, after assembly, the fitting groove 19 is sleeved on the interconnecting piece 18.It is close The 4th kind of fixed form of pallet is sealed as shown in Figure 11, Figure 12, the inner wall of the vessel port 1 be provided with it is radial shelve circle 20, The holding parts 4 are cylinder, and the lower end surface of the holding parts 4 rests on described shelve on circle 20.

For the Straw cap as shown in Figures 1 to 6 without container cover, seal pallet the first fixed form such as Fig. 1, Shown in Fig. 2, the lower end of the spacing ring 13 is provided with axial connecting pole 14, and the lower end outward flanging of the connecting pole 14 is formed The inner wall of button bit circle 15, the holding parts 4 is provided with the recessed circle 16 of the button bit being adapted with 15 shape of button bit circle, after assembly, The recessed circle of the button bit 16 is sleeved on the button bit circle 15.Second of fixed form is as shown in Figure 3, Figure 4, and this fixed form is not It needs to rely on container cover, it is identical as the third fixed form of pallet is sealed in the Straw cap with container cover.The third fixation side Formula is as shown in Figure 5, Figure 6, this fixed form again without rely on container cover, with the Straw cap with container cover in seal pallet The 4th kind of fixed form it is identical.

The variant part of the present invention is provided at least water outlet designated port together, and when nature, water outlet designated port elastic reaction is natural It closes, the liquid in container will not be poured down or forth, and when being pressed downward suction pipe, suction pipe moves down, the lower end crimp portion of suction pipe, on variant part Water outlet designated port open, the liquid in container can flow out, and after unclamping hand, sealing the elastic reaction of pallet makes suction pipe move up, Sealing is formed again, it is simple in structure, it is easy to use.

In addition, due to the effect of inclined seal ring, when container is pressurized, even if generating pressure in container, caused by Pressure also can only make variant part be bonded closer with the bottom of suction pipe, and pressure is bigger, paste tighter, prevent when not drinking or When container is overturned, the liquid in container can flow out automatically, due to said effect, can substantially reduce wall of a container thickness, can The use for largely reducing plastic material, saves product cost, can be by container FOLD AND PACK, just when container does not fill liquid In transport, keeping, also allows for consumer and use and carry, can be used for various containers, drum, spice container, soft packaging bag etc..
