Description
Technical Field
The utility model relates to a sealed anti-fake bottle lid of many perpendicular incision split formula belongs to and relates to container packaging and seals technical field.
Background
The common burst type sealed anti-counterfeiting bottle cap in the current market has the advantages that the vertical notch is added below the transverse notch of the single knife edge, so that the twist-off ring at the bottom end of the bottle cap is separated from the bottle opening together with the bottle cap after twist-off. When the bottle cap is twisted off, the connecting point on the single knife edge is firstly broken, but the connecting point close to the vertical notch is kept connected, external force is applied to the lower twisting ring when the connecting point is twisted off, the existence of the vertical notch enables the twisting ring to burst along the vertical notch, and the twisting ring is still connected with the bottle cap and separated from the bottle cap together with the bottle cap. The practical benefit of this kind of design is, the whole part of bottle lid breaks away from the bottleneck completely, makes the recycle of bottle and bottle lid more convenient like this, greatly increased the feature of environmental protection of product. While eliminating the potential safety risk of a sharp twist-off ring on the mouth of the bottle to the user, especially in the vulnerable groups of babies. However, this technique has problems that, because of the single-slit connecting point method, a tensile force is applied to a material at the time of twisting off, so that the twisting off force is excessively large and the material is not easily twisted off, and the short connecting point used causes the twisting off ring to be separated from the bottle cap in advance, thereby losing the significance of the burst-type bottle cap for environmental protection.

Detailed Description
The invention will be further described with reference to specific embodiments, the advantages and features of the invention will become more apparent as the description proceeds. These examples are merely illustrative and do not limit the scope of the invention in any way. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention, and that such changes and modifications are intended to be included within the scope of the invention.
Referring to fig. 1 to 3, the utility model relates to a sealed anti-fake bottle lid of many perpendicular incision split formula, including bottle lid body 1, the lower part of this bottle lid body 1 is provided with twist-off ring 2 bottle lid body 1 and twist-off ring 2 between be provided with the several incision, all incisions are whole to be set up along circumference (circumferencial direction) of bottle lid body 1.
The incision include long incision 4 and short incision 5, be provided with two long incisions between two adjacent short incisions 5, form incision interval 3 between these two long incisions 4, long incision 4 and adjacent short incision 5 between form tie point 6, short incision quantity is no less than 2, long incision quantity is no less than 4.
The plurality of the notch intervals 3 and the connecting points 6 are arranged along the circumferential direction of the bottle cap body 1, and the notch intervals 3 are arranged between every two adjacent connecting points 6.
Twist off 2 and go up even being provided with several and erect incision 7, erect incision 7 along twist off 2 axial settings of ring, the lower extreme of each perpendicular incision 7 extends to twist off 2 lower border, the upper end extends to the middle part that is close short incision 5, short incision 5 be the setting of T type form with the perpendicular incision 7 that corresponds, the upper end of perpendicular incision 7 and the distance (vertical distance) of the short incision that corresponds be 0.1mm to 1 mm.
The arc length of the long incision is 4mm-20 mm; the arc length of the short cut is 2mm-10 mm; the arc length of the connecting point is 0.1mm-1mm, and the connecting point is specifically adjusted according to the requirements of the twisting force; the arc length of the cut interval is 2-10 mm.
The vertical notch is a semi-permeable notch, and the production process and the specific form of the semi-permeable notch are as follows: in the process of rolling the bottle cap body, the distance between the cutter openings of the two dies is adjusted to enable the distance between the cutter openings of the two dies to be smaller than the wall thickness of the bottle cap, so that obvious rolling traces are left on the bottle cap body by the cutter openings; meanwhile, the distance is larger than 0mm, so that the wall of the bottle cap body cannot be sheared by a knife edge.
The utility model discloses a theory of operation is:
(1) The bottle cap body rotates along the external thread at the bottle mouth of the bottle body under the action of external force (lifting force);
(2) The bottle cap body moves upwards, and the twist-off ring is kept still under the restraint of the reinforcing ring at the bottle mouth of the bottle body;
(3) the tensile force applied to the reinforcing ring by the twist-off ring breaks the connecting point between the long notch and the short notch, and the notch interval and the vertical notch are deformed (cannot be broken at the moment);
(3) The bottle cap body continues to move upwards under the action of external force, at the moment, the upper end of the vertical notch is a fulcrum, the lower end of the vertical notch is a stress point, the region from the upper end of the vertical notch to the lower end of the vertical notch forms a stress force arm, the region from the upper end of the vertical notch to the interval of the notch is a force application force arm, the interval of the notch is a force application point, and the external force is continuously applied, so that a lever system is formed, because the stress force arm is much smaller than the force application force arm, the lever system can amplify the force of the stress point at the lower end of the vertical notch by multiple times, taking the typical application scene of the utility model as an example, the distance from the upper end of the vertical notch to the lower end of the vertical notch is 2.5mm, the shortest distance from the upper end of the vertical notch to the far end of the nearest long notch is 5mm (2 mm of the short notch, 4mm of the long notch, because the vertical notch is, this means that the application of force arm is 5mm, and according to the amplification effect of lever principle, the power that receives of force arm force point is the power that application of force arm force point received, means that the power of force point is twice the power of application of force point, therefore, the power that receives the lower extreme of vertical cut is twice the bottle lid lifting force, and under the practical application condition, because long and short cut length also can be greater than minimum 4mm, lever effect probably is bigger, has greatly reduced the required lifting force of breaking vertical cut lower extreme, and this means the reduction of bottle lid twist-off force. When the lower end of the vertical cut is broken, the force-bearing arm of force can be reduced continuously, and the whole vertical cut can be broken continuously until the whole vertical cut is broken. In the whole process, because the notch interval is a force application point, the internal stress is small, and the fracture cannot occur;
(4) After the vertical cut is disconnected, the whole twist-off ring is disconnected, the reinforcing ring at the bottle mouth of the bottle body loses the restraint on the twist-off ring, and the whole twist-off ring is driven by the cut at intervals to be separated from the bottle mouth along with the bottle cap body.
