Description of the Invention: [Technical Field] The present invention relates to a smashed bottle cap. In more detail, the opening locating structure of the present invention After opening __ predetermined angle, it is positioned, and under the condition of no external force application, it can't automatically return to the direction of the shadow bottle mouth, thereby achieving the effect of positioning. [Prior Art] Fig. 1 depicts a conventional squeezing bottle cap having a pedestal 1 〇 ' and a lid 可 which can be attached to the pedestal 1 Ή. The cover body is connected to the seat 1 by a flexible connecting piece 12. The web 12 is preformed into a folded-back configuration that provides the tab 12 with a fixed angle of less than 90 degrees. Under the condition that no external force is applied, the cover 11 and the base 10 are opened due to the fixed angle of the connecting piece 12. The external force is pressed to press the cover 11', and the shape of the shape is compressed. The cover can be combined with the base 10 to close the bottle. On the contrary, the external force of the cover body 1 is released from the base buckle to release the connecting piece 12, and the cover body is driven to the angle of the above-mentioned shaping angle. Based on the angle of the shaped angle being less than 90 degrees (usually about 45 degrees), the cover body is opened but the ridge (4) is wei σ. The secret is that the problem must be that the wire is enlarged to increase the angle between the cover and the base 〇, so that the bottle mouth is not obscured by the cover 11. This - external force must be applied continuously during the use of the container bottle (adding contents from the mouth to the container, or making the contents from the bottle (4)) to maintain the openness of the bottle mouth, but it is extremely inconvenient to use. The new problem arises. SUMMARY OF THE INVENTION 201226273 The present invention is to solve the problem of shielding the bottle mouth from being unfolded after the cover of the above-mentioned bottle cap is opened. The invention solves the problem of (4) the inscription _ the silk-reducing cover--the position of the lining of the lining of the lining, the 掀 式 式 包 包 包 包 包 包 包 包 包 包 包 包 包 包 包 包 包 包 包 包 包 包 包 包 包 包 包 包 包The base is connected by a flexible joint. The connecting piece is preformed into a folded-fold structure, and the structure has a shape that is less than a degree. The positioning structure includes a reconfigurable bridge member disposed at two ends of the connecting piece, the length of the bridging member is greater than the length of the connecting piece _, and the edges of the upper and lower ends are respectively connected to the cover body and the outer wall of the pedestal . The winding bridge has the ability to deform and return. Under the condition that no external force is applied, the cover body and the base are opened due to the shaping angle of the connecting piece of the 4 pieces. The cover body is pressed by an external force, and the angle of the shaping jaw is compressed, and the cover body can be combined and positioned on the base to achieve the purpose of pasting the bottle cap. Applying - the outer force of the cover body from the base and expanding the angle of the connecting piece to a predetermined critical angle, the bridge member is converted from the forward curve to the reverse curve by its inflection point. _ The joint is bent and deformed to generate a traction pull force on the cover body. The traction pull force causes the following expected effects: - forcing the connecting piece to exhibit a larger expansion than the fixed clip, and in the condition of no external force It cannot be automatically returned. 2. The opening angle of the cover relative to the base is greater than 9 degrees, and the cover is opened without completely obscuring the container mouth. 3. Forcing the above-mentioned cover body with the opening angle greater than 90 degrees to be positioned, and unable to automatically return to the direction of the shielding bottle mouth under the condition of no external force, thereby achieving the purpose of the positioning of the opening position 201226273 [Embodiment] ... It is convenient to explain the thought of the case on the above-mentioned date, which is expressed in the specific example. The implementation of various objects is based on the proportion, size, amount of deformation or displacement that is appropriate for the description, rather than the actual lake ratio. In the following description, similar elements are denoted by the same reference numerals. As shown in the second figure and the m-reduction coffee, the bribe includes a base 20 that is packaged in the reduction ▲ and a cover (5) that can be attached to the base. The cover 30 and the base 20 are - The flexible speed pile κ connecting piece 40 is connected. The web 4 is pre-formed in a folded configuration which provides the joint (four) with an angle of about 45 degrees. The opening and positioning knot (4) comprises a flexible bridge member 位于 at both ends of the connecting piece 4Q, the length (U) of the bridge member 献 is provided for the peak of the connection 2), and the second (2) of the connection (4) is described in The length difference between this _ _, _ pieces 51 _ 4Q is greater than 彳 0_ The best difference is between 1.5 ~ 2, 5mm. The cover 30 and the outer wall of the base 20 are connected to the edges of the upper and lower ends of the bridge 51, respectively. In the figure, the limbs-picked 51_2 outer wall is connected by a rigid solid reinforcement member 52 which reduces the probability of breakage from the marginal end. The bridging member 51 has the ability to deform and return. The crucible shape includes the micro-expansion elasticity generated by the material, and the curved shape of the various curvatures is sufficient for the bridge member 51 to be The external force of deformation begins to occur. As shown in the fourth figure, the cover body 3 is pressed by an external force to be positioned and coupled to the base 2, and the cap is closed. The angle of the sizing angle is compressed to be close to the twist. The bridge member is connected to the outer wall of the base 20 and the cover body 3 in a straight manner, so that no force is generated on the cover buckle. (5) 5 201226273 The cover 3 is made. Detach the base, force, and open the cover to spread the tab 4 继. Following the ( (4) · In this process, the 卞 bridge 51 remains straight, with the cover 3 〇 Move and change direction, and the change of the scale angle of the cover body = and base = 0, at this stage, the bridge member does not deform, and no force acts on the t body 30. That is, when the cover is opened, the inside of the cover is removed, and the left is covered by the seat buckle. However, the tab 4 that is unfolded and over the angle of the shaped angle will enter a: ΙΙΓ85〇Η00^^^~^ as shown in the sixth figure 'expanding the spread angle of the tab 40 until it exceeds the unfolding critical angle When the bridge member 51 is then bent and deformed, the deformation of the material is generated on the cover body 30. The pulling force of the pulling force is increased. The greater the curvature of the bending deformation, the more the pulling force is forced, the more the connecting piece can be forced. 40 appears to be close to 18Q degrees _, _ 3Q phase Wei (four) the greater the opening angle 'and under the condition of no external force, the connecting piece 40 and the bridge member 51 material method • automatic return, according to Position the cover with a split angle greater than 9 degrees. We enlarge the bridge member 51 of the eighth figure to describe the restriction relationship between the curvature of the curved deformation of the bridge member 51 and the return of the cover member 3 and the connecting piece 40. Tangent to the curved surface of the bridge, the center point defines a horizontal reference _yang A), and the curved surface of the bridge 51 intersects the reference line to form an angle (Θ), the angle of the angle is between (4) . The bridge member 5] constitutes a return restriction for the connecting piece 仞 and the cover 3〇. When the central corner (9) is bounded by Ming. ~ Qiu. The connecting angle of the connecting piece 4〇 approaches 180 degrees, which can achieve the best positioning effect. " Applying the cover 30 to the base 2 to return the external force to make the connecting piece 仞Γ C 1 6 201226273 to expand the angle 'to the above critical angle, the bridge 5 The deformation of the material is converted into a straight extension, and no force is applied to the cover body 30. The connecting piece 4 is returned to the angle of the fixed angle, and the cover body 3G is returned to the base 2Q in a slanting manner. Above the upper part, a pressure amount is applied to bond the cover body 3 to the base 2 。. The key of the upper handle to enable the cover of the open cap to be deployed is as follows: 1. The bridge member 51 has a length transition between the connector 51 and the length of the bridge member 51 is greater than the connecting piece 50. The length difference is greater than 1〇_, and the best difference is between 1.5~2_5mm. 2. The bridge member 51 is an article having flexibility and elasticity, and has the ability to deform and return. The force of the wheat shape includes the micro-expansion elasticity generated by the material thereof, and the bending deformation of various curvatures. The critical angle of the tab 40 is matched to the inflection point of the bridge member 51. In the present case, the critical angle of the tab that causes the inflection point of the crucible bridge 51 to be defined is defined in % degrees to extent in the present case. The inflection point of the bridging member is represented by the web extending about 90 degrees. When the deployment angle of the connecting piece 40 is less than the defined critical angle, the bridge 51 exhibits a straight curve or straight line which does not have a pinning effect on the cover 3〇. However, when the connecting piece 40 gradually expands into the near-critical angle of the over-center 4' the bridge member 51 approaches the inflection point with a certain curvature until the connecting piece 4〇 reaches a critical angle, the bridge member 51 reaches the inflection point, Once through the inflection point '4 bridges', the curve (or straight line) from the forward direction is converted to the reverse curve, that is, the bridge-shaped bending deformation as shown. The pair of bridges 51 exhibiting a reverse curve, 201226273 The reconnection of the connecting piece 40 and the cover 30 is restricted. As shown in the ninth figure, the graph constituting the experimental data describes that the inflection point of the bridge member 51 in the present case exhibits a critical angle of about four degrees. The tenth figure is a description of the case where the bridge member 51 curves from the forward curve (or straight line) to the approaching inflection point and then to the reverse curve. 4. The bridge member 51 exhibiting a reverse curve having an angle between the curved surface and the reference line passing through the curved center of the mass is 8. ~58. In this case, the retraction restriction of the connecting piece 4〇 and the cover 3〇 is excellent, and the deployment angle of the connecting piece 4〇 can be made close to 18 degrees ′ to achieve an optimum swaying positioning effect. The analysis of the soil on the raft can prove that the invention has a sturdy and sturdy positioning effect, although the case is based on a best embodiment, but the skill can not deviate from this _ God and Fan _ to make a variety of different forms of change. The above embodiments are only used to illustrate the case and are not intended to limit (4) of the case. All kinds of materials or changes that are not in violation of this blasphemy are all patent applications.
