Description
[technical field]
The present invention relates to a kind of plastic bottle closure.
[background technology]
Current plastic bottle closure is commercially used widely, particularly beverage filling industry.But the structure of current plastic bottle closure exists following deficiency: 1, when bottle cap is connected with the bottleneck of bottle, owing to there is the pressure of expansion in beverage bottle, depositing in process for a long time, there is cracking phenomena in top flat and the lateral plate connected position of plastic bottle closure, 2, bottle cap and bottleneck screw be connected time, bottleneck has outside tension force to bottle cap, and bottleneck has the power of upwards pushing up to bottle cap, so deposit in process at beverage bottle, cracking phenomena appears in top flat and the lateral plate connected position of plastic bottle closure, 3, can exist aging in plastics long-term storage process, toughness reduces, so easily there is stress crack in plastic bottle closure top flat this weak location that to be connected with lateral plate, so above three aspects all can cause plastic bottle closure to damage and beverage waste, the more important thing is that such plastic bottle closure can not see difference when just starting to be connected with bottleneck, that is in initial a period of time that plastic bottle closure is connected with bottleneck, cracking can't be there is in plastic bottle closure, but cracking is there is in the process deposited, therefore, the plastic bottle closure of this spline structure brings very large puzzlement to drink producers, cause the increase of productive costs, because can not judge during beverage filling which plastic bottle closure there will be cracking situation.In addition, the leak tightness of traditional plastic bottle closure is poor, is still in the phenomenon of beverage seepage after conventional plastic bottle cap is connected with bottleneck thread.
Therefore, the present invention produces based on above deficiency just.
[summary of the invention]
The present invention seeks to overcome the deficiencies in the prior art, provide a kind of structure simple, do not occur the plastic bottle closure ftractureed.
The present invention is achieved by the following technical solutions:
A kind of plastic bottle closure, it is characterized in that: comprise top flat 1, described top flat 1 outward flange is provided with ring-type lateral plate 2 that is one-body molded with it and that extend towards top flat 1 side, described lateral plate 2 inwall is provided with the screw thread matched with the screw thread of bottleneck 3, the position that described top flat 1 connects with lateral plate 2 is provided with boss 4 that is one-body molded with the two and that extend to plastic bottle closure opening side, boss 4 described in when plastic bottle closure is connected with bottleneck 3 coordinates with the bottleneck 31 of bottleneck 3 is inconsistent, and the thickness H of described boss 4 is greater than the thickness h of top flat 1.
Plastic bottle closure as above, is characterized in that: the inner side of described lateral plate 2 is also provided with the inner sealing ring 5 for closed bottleneck 3 inwall.
Plastic bottle closure as above, it is characterized in that: between described inner sealing ring 5 and lateral plate 2, be also provided with the covering closed loop 6 for closed bottleneck 3 outer wall, form mating groove 7 between described covering closed loop 6 and inner sealing ring 5, when plastic bottle closure is connected with bottleneck 3, the upper end of bottleneck 3 to screw in mating groove 7 and connects with boss 4.
Plastic bottle closure as above, is characterized in that: the thickness H of described boss 4 is 1.3 times of top flat 1 thickness h to 2 times.
Plastic bottle closure as above, is characterized in that: the thickness h of described top flat 1 is 0.8mm to 1.3mm.
Compared with prior art, the present invention has the following advantages:
1, the position that top flat of the present invention connects with lateral plate is provided with boss that is one-body molded with the two and that extend to plastic bottle closure opening side, boss described in when plastic bottle closure is connected with bottleneck coordinates with the bottleneck of bottleneck is inconsistent, and the thickness H of described boss is greater than the thickness h of top flat.Therefore, the design of boss greatly strengthen the mechanical strength of top flat and lateral plate connected position, makes beverage top flat and lateral plate connected position in the process deposited there will not be cracking, improves the quality of product, has stopped plastic bottle closure cracking and the loss that brings.
2, the inner side of lateral plate of the present invention is also provided with the inner sealing ring for closed bottleneck inwall, the covering closed loop for closed bottleneck outer wall is also provided with between inner sealing ring and lateral plate, form mating groove between described covering closed loop and inner sealing ring, when plastic bottle closure is connected with bottleneck, the upper end of bottleneck to screw in mating groove and connects with boss.When plastic bottle closure is connected with bottleneck, boss and bottleneck offset and seal, inner sealing ring coordinates with bottleneck inwall and seals, covering closed loop coordinates with bottleneck outer wall and seals, therefore exist multi-sealed between bottleneck and plastic bottle closure, stop the risk of beverage from seepage in bottle completely, improve the quality of product.
3, structure of the present invention is simple, with low cost, is applicable to promoting.
[accompanying drawing explanation]
Fig. 1 is the cutaway view of plastic bottle closure of the present invention;
Fig. 2 is the assembling schematic diagram of plastic bottle closure of the present invention and bottleneck.
[detailed description of the invention]
Below in conjunction with accompanying drawing, the invention will be further described:
A kind of plastic bottle closure, comprise top flat 1, described top flat 1 outward flange is provided with ring-type lateral plate 2 that is one-body molded with it and that extend towards top flat 1 side, described lateral plate 2 inwall is provided with the screw thread matched with the screw thread of bottleneck 3, the position that described top flat 1 connects with lateral plate 2 is provided with boss 4 that is one-body molded with the two and that extend to plastic bottle closure opening side, boss 4 described in when plastic bottle closure is connected with bottleneck 3 coordinates with the bottleneck 31 of bottleneck 3 is inconsistent, and the thickness H of described boss 4 is greater than the thickness h of top flat 1.Therefore, the design of boss 4 greatly strengthen top flat 1 and the mechanical strength of lateral plate 2 connected position, makes beverage top flat 1 and lateral plate 2 connected position in the process deposited there will not be cracking, improves the quality of product, has stopped plastic bottle closure cracking and the loss that brings.
The inner side of described lateral plate 2 is also provided with the inner sealing ring 5 for closed bottleneck 3 inwall, the covering closed loop 6 for closed bottleneck 3 outer wall is also provided with between described inner sealing ring 5 and lateral plate 2, form mating groove 7 between described covering closed loop 6 and inner sealing ring 5, when plastic bottle closure is connected with bottleneck 3, the upper end of bottleneck 3 to screw in mating groove 7 and connects with boss 4.When plastic bottle closure is connected with bottleneck, boss 4 and bottleneck 31 offset and seal, inner sealing ring 5 coordinates with bottleneck inwall and seals, covering closed loop 6 coordinates with bottleneck outer wall and seals, therefore exist multi-sealed between bottleneck and plastic bottle closure, stop the risk of beverage from seepage in bottle completely, improve the quality of product.
The thickness H of described boss 4 is 1.3 times of top flat 1 thickness h to 2 times, and the thickness h of described top flat 1 is 0.8mm to 1.3mm.Thickness h through research discovery top flat 1 is more than 0.8mm, and more than 1.3 times that the thickness H of boss 4 are designed to top flat 1 thickness h can obtain good effect, stop the cracking phenomena of plastic bottle closure during beverage storing completely.And when the thickness h of top flat 1 is more than 1.3mm, when the thickness H of boss 4 is more than 2 times of top flat 1 thickness h, the increase of production material cost can be caused again, therefore, the thickness h of top flat 1 is set to 0.8mm to 1.3mm and is advisable, and the thickness H of boss 4 is that 1.3 times of top flat 1 thickness h are advisable to 2 times.
