Description

The bottle cap of structural development

The utility model is a kind of improvement of Bottle cap structure, specifically, is meant a kind of bottle cap with lid and pilfer band made from plastics.

The shape and structure of general bottle cap, see also Fig. 1～shown in Figure 3, it mainly comprises a lid 10, the inner face of this lid 10 is provided with pad 11 and lira 12 in the leak-stopping, so that make lid 10 be combined on bottleneck 23, and utilize this leak-stopping ring grain (or filling up in the leak-stopping) 11 to increase the bonding tightness of lids 10 and bottleneck 23.

The opening port periphery of this lid 10, the one-body molded port internal diameter pilfer band 20 smaller of establishing than lid 10 internal diameters, form at interval hole 21 and slice 21 ' for being connected at interval with cutting mode between this pilfer band 20 and the lid 10, and in the inner face of this pilfer band 20, ring is established the short fin 22 of several inlay cards in addition.System is pressed into bottleneck 23 with capsuling machine with bottle cap during capping, and makes the inlay card of pilfer band 20 lack the bottom that fin 22 is embedded in bottle opening.

This pilfer band of commonly using 20 is one-body molded with lid 10, and for making the short fin 22 of this inlay card can be embedded in bottleneck 23 really, so the thickness of this pilfer band 20 is set as at least and lid 10 uniform thickness, and material and lid are all hard material, attempt is to enclose urgent this bottleneck 23 in the pilfer band 20, but this kind technical application is wrong, when when mainly being capping the bottle cap press seal being gone into bottleneck 23, pilfer band 20 will bear the pressure of two aspects, downward pressure during first capping, another is the horizontal pressure that strutted by bottleneck 23, under the situation of pilfer band 20 and lid 10 equal thickness, promptly be not easy the thread segment by bottleneck 23, make and pilfer band 20 is a hard material, easier this pilfer band 20 that causes is cracked (probability is about 10% to 20%); And the interval hole 21 that forms with cutting mode and at interval slice 21 ', because hole 21 causes surface of discontinuity at interval, so the pressure of lid 10 when lower seal is pressed can only also cause interval slice 21 ' fracture easily by this interval slice 21 ' bear.Generally speaking, the damage probability of this kind bottle cap is too high, for manufacturer, and the burden that causes cost to increase.Moreover, the short fin 22 of this inlay card is because of its curtailment, so often after capping is finished, the open end of the short fin 22 of this inlay card does not push against the thread segment bottom in this bottleneck 23 really, produce gap improperly, so when the user rotates lid 10, after need rotate a predetermined circle with it usually, just can make this interval slice 21 ' fracture, this also belongs to the shortcoming of commonly using bottle cap.

The purpose of this utility model provides a kind of bottle cap of structural development, to reach the shortcoming that overcomes located by prior art, the damage rate of bottle cap when capping is reduced significantly, improves the quality of products, and reduces production costs.

The utility model is achieved in that the pilfer band that it mainly comprises lid and is positioned at this lid below, and main system will form several bridging points with seamless cutting between this pilfer band and this lid; The internal diameter system of this pilfer band is slightly larger than the internal diameter of this lid, but its thickness is slightly thin than this lid thickness, to improve the toughness and the elasticity of pilfer band; The long fin of several inlay cards of the inside oblique extension tool suitable length in inner face footpath of the external end edge of this pilfer band.

The utility model has the advantages that: this bottle cap is press-sealed in bottleneck, this pilfer band can evenly bear the downward pressure of capping, the outer support pressure of bottleneck then is absorbed by the long fin elasticity closing of this inlay card, so cause pilfer band to burst apart when capping or the damage of product rate of the long fin of inlay card fracture is minimized; And the long fin of this inlay card was able to the bottom edge that certain inlay card is closely against this bottleneck after capping was finished, and the rotation lid can make the bridging point fracture immediately, and lid is separated with pilfer band.

Accompanying drawing of the present utility model is simply described as follows:

The schematic perspective view of bottle cap is commonly used by Fig. 1 system.

The cross-sectional schematic of bottle cap is commonly used by Fig. 2 system.

The combination cross-sectional schematic of bottle cap and bottleneck is commonly used by Fig. 3 system.

Fig. 6 is that the action scheme drawing is analysed and observe in the combination of the utility model and bottleneck.

Fig. 7 is that cross-sectional schematic is finished in the combination of the utility model and bottleneck.

Fig. 8 is the use scheme drawing of outwarding winding of the present utility model.

Below we provide better embodiment of the utility model according to Fig. 4～Fig. 8, and described in detail, so that ins and outs of the present utility model further are provided.

See also Fig. 4 and Fig. 5, the utility model mainly comprises lid 30, and a pilfer band 40 is established in the below of this lid 30; Be to form several bridging points 41 between this pilfer band 40 and this lid 30 with seamless cutting; The internal diameter system of this pilfer band 40 is slightly larger than the internal diameter of this lid 30, and its thickness is slightly thin than the thickness of this lid 30, in the long fin 42 of several inlay cards of its inside oblique extension tool suitable length in external end edge inner face footpath.

By above-mentioned structure, please cooperate and consult Fig. 6～shown in Figure 8, the utility model utilizes this lid 30 of capsuling machine press seal when bottleneck 50, this pilfer band 40 is big because of its thinner thickness and internal diameter than lid 30 internal diameters, so can waltz through bottleneck 50, and the long fin of inlay card 42 in it can be oppressed by the screw thread of bottleneck 50 and lean in this pilfer band 40 during by bottleneck 50, and have more bullet because of the thickness attenuation of this pilfer band 40, toughness, so its pilfer band of commonly using more has enough spaces and elastic energy to cooperate by this bottleneck 50, the elastic space that allows the long fin 42 of this inlay card have appropriateness is subjected to the compressing of these bottleneck 50 thread segments and interior leaning on makes this pilfer band 40 can evenly bear the downward pressure of capping and the outer support pressure of bottleneck 50.So the utility model causes pilfer band 40 to burst apart in the process of capping or the damage of product rate of long fin 50 fractures of inlay card can minimize.In addition, this bridging point 41 is because of being with seamless cutting mode moulding, so still locating in its cut place is an entity of conflicting each other, so downward pressure during capping, this cut place is contacted more closely, capping pressure is then on average born by a continuous face, but not is born by bridging point 41 separately, does not have bridging point 41 fractures so definitely can bear the pressure of capping.

Again as shown in Figure 7, it is the assembled sectional view after capping is finished, the utility model is long because of the length of the long fin 42 of this inlay card, elasticity is preferable, so can it open the bottom edge that ora terminalis is closely against these bottleneck 50 thread segments, and rotation the mat thread segment makes that lid 30 rotations rise during lid 30 at that time, this bridging point 41 is produced revolves pulling force, and the effect that is tight against of the long fin 42 of mat inlay card, even this bridging point 41 of event is immediately in its fracture at that time of rotation lid 30, this lid 30 promptly separates with this pilfer band 40.

In sum, though the change significantly of the non-structure of the utility model, owing to change the length of the long fin 42 of internal diameter, thickness and inlay card of this pilfer band 40, can solve the problem of commonly using fully, improve the quality of products effectively, and the rate of effectively reducing the number of rejects and seconds, reduce and manufacture and consuming cost.
