Detailed description of the invention

Referring to figs. 1 through Figure 14, a kind of tack Straw cap with automatic sealing function, comprise bottleneck 1, suction pipe 2 is installed in described bottleneck 1 and by elastomeric material as sealing pallet made by silica gel etc., described sealing pallet is by the variant part 3 of taper, the holding parts 4 being positioned at the large end of variant part 3 and the sealing 5 being positioned at described variant part 3 lower end are formed, the center of described sealing 5 is provided with apopore 6, the lower end of described suction pipe 2 is flat taper, the center of described suction pipe 2 lower end surface is closing plate 7, the profile of described closing plate 7 is greater than the profile of described apopore 6, the arranged outside of described closing plate 7 has water inlet 8, during state of nature, the lower end surface of described suction pipe 2 is close to described sealing 5, described water inlet 8 is not communicated with described apopore 6.

The Straw cap as shown in Figures 1 to 6 that described bottleneck 1, suction pipe 2 and sealing pallet are formed can be used alone, as the Straw cap etc. of packaging bag, bottleneck 1 also can be one-body molded with bottle, also can enter as shown in Fig. 7 to Figure 14, described bottleneck 1 is threaded bottle cap 9, and described bottle cap 9 is provided with the sipper pore 10 supplying the upper end of described suction pipe 2 to stretch out.

For Straw cap as shown in Figures 1 to 6, radial spacing ring 16 can be provided with at the top of described bottleneck 1 or inwall, the outer wall of described suction pipe 2 is provided with upper limit circle 11 and lower limit circle 12, after assembling, described spacing ring 16 is between described upper limit circle 11 and lower limit circle 12, spacing ring 16 blocks upper limit circle 11 and lower limit circle 12, prevents suction pipe to be pulled out or is pressed in bottle.

For the Straw cap such as shown in Fig. 7 to Figure 14, the structure of suction pipe is constant, namely the outer wall of described suction pipe 2 is provided with upper limit circle 11 and lower limit circle 12, after assembling, described upper limit circle 11 and lower limit circle 12 lay respectively at the both sides up and down of bottle cap 9, the sidewall of sipper pore 10 blocks upper limit circle 11 and lower limit circle 12, prevents suction pipe to be pulled out or is pressed in bottle.

For the Straw cap of the band bottle cap such as shown in Fig. 7 to Figure 14, as shown in Figure 7, Figure 8, described holding parts 4 is sandwiched between described bottle cap 9 and the end face of bottleneck 1 the first fixed form of sealing pallet.The second fixed form of sealing pallet as shown in Figure 9, Figure 10, the top of described bottle cap 9 is provided with the mounting part 13 stretched in described bottleneck 1, the lower end of described mounting part 13 outwards turns down and forms button bit ring 14, the inwall of described holding parts 4 is provided with the groove 15 adapted with described button bit ring 14 shape, after assembling, described groove 15 is sleeved on described button bit ring.The third fixed form of sealing pallet is as shown in Figure 11, Figure 12, the inwall of described bottleneck 1 is provided with radial support portion 20, the inner side of described support portion 20 upwards turns down and forms connecting portion 21, described holding parts 4 is provided with the fitting recess 22 that Open Side Down, after assembling, described fitting recess 22 is sleeved on described connecting portion 21.4th kind of fixed form of sealing pallet is as shown in Figure 13, Figure 14, and the inwall of described bottleneck 1 is provided with radial shelves circle 23, and described holding parts 4 is cylindrical, shelves on circle 23 described in the lower end surface of described holding parts 4 rests.

For the Straw cap not with bottle cap as shown in Figures 1 to 6, the first fixed form of sealing pallet as shown in Figure 1 and Figure 2, the lower end of described spacing ring 16 is provided with joint pin 17, the lower end of described joint pin 17 outwards turns down and forms button bit circle 18, the inwall of described holding parts 4 is provided with the recessed circle 19 of button bit adapted with described button bit circle 18 shape, after assembling, the recessed circle of described button bit 19 is sleeved on described button bit circle 18.As shown in Figure 3, Figure 4, this fixed form does not need to rely on bottle cap the second fixed form, identical with the third fixed form sealing pallet in the Straw cap of band bottle cap.As shown in Figure 5, Figure 6, this fixed form does not need to rely on bottle cap the third fixed form equally, identical with the 4th kind of fixed form sealing pallet in the Straw cap of band bottle cap.

The lower end of suction pipe of the present utility model is flat taper, during state of nature, the lower end surface of suction pipe is close to sealing, water inlet is not communicated with apopore, liquid in bottle can not be poured down or forth, to when pressing down suction pipe, suction pipe moves down, the conical end end face of suction pipe is through apopore, water inlet on suction pipe is communicated with in bottle, liquid in bottle just can flow out, after unclamping hand, the variant part reset of sealing pallet moves, simultaneously, the conical end of the hole wall extruding suction pipe of apopore, make suction pipe moves, again sealing is formed between the lower end surface of suction pipe and sealing, structure is simple, easy to use.

In addition, when bottle pressurized, even if produce pressure in bottle, its pressure produced also can only make the bottom of variant part and suction pipe fit tightr, pressure is larger, paste tighter, prevent when not drinking or bottle is overturned time, liquid in bottle can flow out automatically, due to above-mentioned effect, the wall thickness of bottle can be reduced greatly, the use of plastic material can be reduced in a large number, save cost of product, when bottle does not fill liquid, can by bottle FOLD AND PACK, be convenient to transport, keeping, also be convenient to customer use and carry, can be used for various container, drum, spice container, soft packaging bag etc.
