Description

Open positioning structure of the open bottle cap

The invention relates to a bottle cap, and more particularly, the invention attaches a novel opening and positioning structure of the bottle cap, and the opening positioning structure enables the cap to be positioned after being opened for a predetermined angle, without external force. Under the applied conditions, it is impossible to automatically return to the direction of the masking bottle mouth, thereby achieving the effect of positioning.

The first figure depicts a conventional cocked closure having a base 10 that is sealed to the mouth of the container and a cover 11 that can be attached to the base 10. The cover 11 and the base 10 are connected by a flexible connecting piece 12. The web 12 is preformed into a folded 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 cover body 11 is pressed by an external force, and the angle of the fixed angle is compressed, and the cover body 11 can be coupled to the base 10 to achieve the purpose of closing the bottle cap. On the contrary, an external force for disengaging the cover 11 from the base 10 is applied, and the connecting piece 12 is released, and the cover 11 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 11 is slanted to shield the mouth of the bottle. In order to solve this problem, it is necessary to apply an expansion force to the cover 11 beyond the angle of the connecting piece 12 to enlarge the angle between the cover 11 and the base 10 until the bottle opening is not covered by the cover 11. This external force must be continuously applied during the process of using the container mouth (adding contents from the bottle mouth to the container or pouring the contents out of the bottle mouth) to maintain the openness of the bottle mouth, but it is extremely inconvenient to use. The new problem arises.

The invention solves the problem that the cover of the above-mentioned bottle cap is not unfolded after being opened, thereby shielding the bottle mouth.

The method for solving the problem of the present invention is to attach a novel opening and positioning structure to the bottle cap, and the pop-up bottle cap comprises a base packaged on the bottle mouth of the container and a cover body coverable on the base. The cover and the base are connected by a flexible connecting piece. The tab is preformed into a folded configuration that provides the tab with a fixed angle of less than 90 degrees. The opening and positioning structure comprises a flexible bridge member disposed at two ends of the connecting piece. The length of the bridge 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 base. The flexible bridge has the ability to deform and retract. Under the condition that no external force is applied, the cover body and the base are opened due to the fixed angle of the connecting piece. The cover body is pressed by an external force, and the angle of the shaping angle is compressed, and the cover body can be combined and positioned on the base to achieve the purpose of closing the bottle cap. Applying an external force that disengages the cover from the base and enlarging the angle of the tab until it exceeds an expected critical angle, the bridge transitions from a forward curve to a reverse curve through its inflection point. The bridge member is bent and deformed to generate a pulling force on the cover body, and the traction pulling force causes the following expected effects:

1. Forcing the tab to exhibit an expansion greater than the angle of the set, and cannot be automatically returned without external force.

2. The opening angle of the cover body relative to the base is greater than 90 degrees, and the cover body is opened without completely obscuring the container bottle mouth.

3. The cover body with the above-mentioned opening angle greater than 90 degrees is forced to be positioned, and cannot be automatically returned to the direction of the shielding bottle mouth under the condition of no external force, thereby achieving the purpose of positioning.

For the convenience of the description, the central idea expressed in the column of the above summary of the present invention is expressed by a specific embodiment. Various items in the embodiments are depicted in terms of ratios, dimensions, amounts of deformation, or displacements that are suitable for illustration, and are not drawn to the proportions of actual elements, as set forth above. In the following description, like elements are denoted by the same reference numerals.

As shown in the second and third figures, a pop-up bottle cap is provided. The pop-up cap includes a base 20 that is sealed at the mouth of the container and a cover 30 that can be fixedly attached to the base 20. The cover 30 and the base 20 are connected by a flexible connecting piece 40. The tab 40 is preformed into a folded configuration that provides the tab 40 with a fixed angle of about 45 degrees. The open positioning structure 50 includes a flexible bridge member 51 at both ends of the connecting piece 40. The length (L1) of the bridge member 51 is greater than the length (L2) of the connecting piece 40. The length (L2) of the connecting piece 40 is described in the seventh figure. In the embodiment of the present invention, the length difference between the bridge member 51 and the connecting piece 40 is greater than 1.0 mm, and the optimum difference is between 1.5 and 2.5 mm.

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. The figure further describes that the two ends of the bridge member 51 are connected with the base member 20 and the outer wall of the cover body 30 by a rigid solid reinforcement member 52. The reinforcement member 52 strengthens the marginal end of the bridge member 51 and reduces the margin from the margin. The probability of a break in the end. The bridge member 51 has the ability to deform and retract, and the deformability includes micro-expansion elasticity due to its material, and bending deformation of various curvatures. This deformability is generated when the bridge member 51 is subjected to an external force sufficient to deform it.

As shown in the fourth figure, the cover 30 is pressed by an external force to be coupled to the base 20, and the cap is closed. The angle of the shaped angle is compressed by nearly 0 degrees, and the bridge member 51 is connected to the outer wall of the base 20 and the cover 30 in a straight manner, so that no force is generated on the cover 30.

As shown in the fifth figure, an external force for disengaging the cover 30 from the base 40 is applied, and the cover 30 is opened so that the deployment angle of the connecting piece 40 exceeds the angle of the fixed angle. In this process, the bridge member 51 remains flat and extends in direction as the cover 30 moves, and the angle of connection with the cover 30 and the base 20 also changes. At this stage, the bridge member 51 is changed. No deformation occurs, and no force acts on the lid body 30. That is, when the external force of the opening cover 30 disappears, the connecting piece 40 is returned to the angle of the fixed angle, and the cover 30 is slid back and shielded above the base 20. However, the tab 40 that unfolds and exceeds the angle of the shaped angle will enter a critical angle (about 85° to 100°) that will cause the bridge 51 to transition from a straight extension to a curved bend.

As shown in the sixth figure, when the deployment angle of the connecting piece 40 is enlarged until it exceeds the deployment critical angle, the bridge member 51 is then subjected to bending deformation, and the bending deformation generates a downward pulling force on the cover 30, and the bending is performed. The greater the curvature of the deformation, the greater the pulling force, the more the web 40 can be forced to extend to a full extent of 180 degrees, the greater the angle of the lid 30 relative to the base 20, and no external force. Under the condition of the action, the connecting piece 40 and the bridge member 51 cannot be automatically returned, and accordingly, the cover body with the opening angle greater than 90 degrees is positioned.

We enlarge the bridge member 51 in the eighth figure to describe the restriction relationship between the curvature of the bending deformation of the bridge member 51 and the return of the cover body 30 and the connecting piece 40. A horizontal reference line (Line A) is defined at a center point of the curved surface of the bridge, and a curved surface of the bridge 51 intersects the reference line to form an angle (θ), the angle of the angle is between 8 The bridge member 51 constitutes a return limit for the connecting piece 40 and the lid 30 at °~58°. When the angle (θ) is between 48° and 58°, the deployment angle of the connecting piece 40 approaches 180 degrees, and the optimal positioning effect can be achieved.

Applying an external force to the cover 30 to return the direction of the base 20 to reduce the deployment angle of the connecting piece 40. When the critical angle is passed, the bridge member 51 is converted from a bending deformation to a straight extension. The force is not applied to the cover 30, and the connecting piece 40 is returned to the angle of the fixed angle. The cover 30 is slanted and shielded above the base 20, and the amount of pressure is applied. The cover 30 can be coupled to the base 20.

In summary, the key points for the present invention to enable the deployment of the lid of the open cap are:

1. The bridge member 51 and the connecting piece 40 have a length difference. The length of the bridge member 51 is larger than the connecting piece 50, and the length difference is greater than 1.0 mm, and the optimum difference is between 1.5 and 2.5 mm.

2. The bridging member 51 is an article having flexibility and elasticity, and has the ability of deformation and re-entry. The deformability includes micro-expansion elasticity due to its material, and bending deformation of various curvatures.

3. The critical angle of the connecting piece 40 is matched with the inflection point of the bridge member 51. In the present case, the critical angle of the tab that causes the bridge 51 to generate an inflection point is defined as 85 degrees to 100 degrees. In the present case, the inflection point of the bridge is represented by the web being about 90 degrees apart. When the deployment angle of the connecting piece 40 does not reach the defined critical angle, the bridge 51 exhibits a forward curve or straight line which does not have a pinning effect on the cover 30. However, during the process in which the connecting piece 40 gradually expands to a near critical angle, the bridge member 51 approaches the inflection point with a certain curvature until the connecting piece 40 reaches a critical angle, and the bridge member 51 reaches the inflection point once By this inflection point, the bridge member 51 is converted from a forward curve (or straight line) to a reverse curve, that is, an arch-shaped curved bend as shown. The bridge 51 exhibiting a reverse curve restricts the return of the connecting piece 40 and the cover 30. As shown in the ninth figure, the experimental data constitutes a graph depicting that the inflection point of the bridge member 51 in the present case is expressed at a critical angle of about 90 degrees to the connecting piece 40. The tenth figure is a case where the bridge 51 is described from a forward curve (or straight line) to a near inflection point and then to a reverse curve.

4. The bridge member 51 exhibiting a reverse curve has excellent retraction restriction on the connecting piece 40 and the cover 30 when the angle between the curved surface and the reference line passing through the center of curvature thereof is between 8° and 58°. The performance of the connecting piece 40 can be extended to 180 degrees, and the optimal positioning effect can be achieved.

Based on the above theoretical analysis, it can be proved that the present invention has the effect of positioning the bottle cap. Although the present case is illustrated by a preferred embodiment, the skilled person can perform various forms without departing from the spirit and scope of the case. change. The above embodiments are only used to illustrate the present case and are not intended to limit the scope of the present invention.
