Detailed Implementation

[0018] Please refer to Figures 1 to 9 This invention provides a flip-top, typically mounted on the packaging body, to help users remove the contents from the packaging. It is understood that the contents can be various suitable products. In a specific embodiment, the contents are sheet materials such as tissues or wet wipes. In other embodiments, they can be other products of suitable size that can be removed from the extraction port 102. No limitation is made here.

[0019] The hinged cover includes a base 10, a cover 20, and a connecting part 30.

[0020] The substrate 10 is configured to be fixed to the packaging body. Specifically, the substrate 10 includes a base plate 101 and a lower sidewall 11 disposed on the base plate 101. The base plate 101 includes a pull-out port 102 penetrating the base plate 101. At the same time, an adhesive layer may be disposed on the base plate 101 to fix the base plate 101 to the packaging body. The lower sidewall 11 is disposed approximately perpendicular to the surface of the base plate 101 and extends upward. The upward side refers to the side opposite to the packaging body when the substrate 10 is fixed to the packaging body. In this embodiment, the lower sidewall 11 is disposed along the outer edge of the base plate 101.

[0021] The cover 20 includes a cover plate 201 and an upper sidewall 21 disposed on the cover plate 201. The upper sidewall 21 is disposed approximately perpendicular to the surface of the substrate 101 and extends downward. The lower side refers to the side facing the packaging body when the base 10 is fixed on the packaging body. At the same time, the cover 20 is located above the base 10, such that the upper sidewall 21 of the cover 20 extends towards the base 10. In addition, the upper sidewall 21 and the lower sidewall 11 are correspondingly disposed. The corresponding disposal means that when the cover 20 is closed on the base 10, the positions of the upper sidewall 21 and the lower sidewall 11 correspond.

[0022] Furthermore, the lower sidewall 11 is configured into a closed shape.

[0023] Furthermore, the cover 20 also includes a barrier that extends downwards, and when the cover 20 is placed on the base 10, the barrier forms a seal with the lower sidewall 11.

[0024] The connecting portion 30 is configured to connect the base 10 and the cover 20. The connecting portion 30 includes a main support portion 31 and a pair of side support portions 32. The main support portion 31 is located in the middle of the connecting portion 30, and the pair of side support portions 32 are located on opposite sides of the main support portion 31. The upper end 322 of each side support portion 32 is connected to the upper sidewall 21 of the cover 20, and the lower end 321 is connected to the lower sidewall 11 of the base 10. Each side support portion 32 includes a side line away from the main support portion 31. A plane passing through the pair of side lines is defined as a base surface 330. In this embodiment, the side support portion 32 located to the right of the main support portion 31 includes a first side line 3301 away from the main support portion 31, and the side support portion located to the left of the main support portion 31 includes a second side line 3302 away from the main support portion 31. The base surface 330 is formed by... The plane defined by the first side line 3301 and the second side line 3302, and the main support part 31 is configured such that: when the cover 20 is in the first open position, at least a portion of it protrudes from the base surface 330; when the cover 20 is in the second open position, it is recessed and located inside the base surface 330, so that the cover 20 can be stably maintained in the first open position or the second open position. In addition, it can be understood that since a part of the side support part 32 is fixedly connected to the main support part 31, when the position of the main support part 31 changes, the position and shape of a part of the side support part 32 also change at the same time. However, the first side line 3301 and the second side line 3302 located at the far end will still be able to maintain a straight shape, so that the surface defined by the first side line 3301 and the second side line 3302 maintains a planar state, that is, the base surface 330 remains planar.

[0025] Specifically, the main support 31 includes an upper connecting section 311 and a lower connecting section 312. The upper end of the upper connecting section 311 is connected to the upper sidewall 21, and the lower end of the lower connecting section 312 is connected to the lower sidewall 11. Simultaneously, the lower end of the upper connecting section 311 is connected to the upper end of the upper connecting section 311. The upper connecting section 311 includes a first outer surface 3110, and the lower connecting section 312 includes a second outer surface 3120. The first outer surface 3110 and the second outer surface 3120 are inclined and connected to the wiring 310. When the cover 20 is in the first open position, at least the wiring 310 and a portion of the first outer surface 3110 and the second outer surface 3120 adjacent to the wiring 310 protrude from the base surface 330. It can be understood that when the cover 20 is in the first open position, the upper connecting section 311 and the lower connecting section 312... The connecting section 312 and the side support 32 form a triangular support structure, which allows the cover 20 to be stably maintained in the first open position. When the user applies force to continue opening the cover 20, the upper connecting section 311 and the lower connecting section 312 rotate around the wire 310. When they rotate past the equilibrium point, the upper connecting section 311 and the lower connecting section 312 are located inside the base surface 330, so that the upper connecting section 311, the lower connecting section 312 and the side support 32 form a reverse triangular support, thereby allowing the cover 20 to be located and maintained in the second open position. At the same time, when the cover 20 is in the second open position, the opening angle of the cover 20 is greater than the opening angle of the cover 20 in the first open position. That is, when the cover 20 is located and maintained in the second open position, the cover 20 is in a fully open state, and when the cover 20 is in the first open position, the cover 20 is in a slightly open state.

[0026] Furthermore, when the cover 20 is in the first open position, the distance between the wiring 310 and the base surface 330 is greater than or equal to 1.5 mm.

[0027] Furthermore, when the cover 20 is in the first open position, the angle between the first outer surface 3110 and the second outer surface 3120 is 150°-170°.

[0028] Furthermore, when the cover 20 is in the first open position, the angle between the cover plate 201 and the substrate 101 is less than 60°, and when the cover 20 is in the second open position, the angle between the cover plate 201 and the substrate 101 is greater than 120°.

[0029] Furthermore, the bending stiffness of the main support portion 31 should be greater than that of the side support portion 32, so that when the cover 20 is in the first open position, the main support portion 31 provides stable support. By making the bending stiffness of the main support portion 31 greater than that of the side support portion 32, it is ensured that when opened to the first position, the deformation mainly occurs in the side support portion 32, while the main support portion 31 can quickly contact the lower side wall 11 to form stable support, providing a clear sense of segmentation.

[0030] Furthermore, the thickness of the main support portion 31 is greater than that of the side support portion 32, so that the bending stiffness of the main support portion 31 should be greater than that of the side support portion 32. In a preferred embodiment, the thickness of the main support portion 31 is greater than or equal to 1.3 mm, and the thickness of the side support portion 32 is less than or equal to 1 mm. Preferably, the ratio of the thickness of the main support portion 31 to the thickness of the side support portion 32 is 1.3 to 4.0, for example, the thickness of the main support portion 31 is 1.3 mm to 1.8 mm, and the thickness of the side support portion 32 is 0.5 mm to 1.0 mm.

[0031] Furthermore, in order to enable the cover 20 to close onto the base 10, and to enable the cover 20 to move stably toward the base 10, the main support part 31 includes a recess 313. The recess 313 is provided on the side of the main support part 31 facing the extraction port 102 and is correspondingly provided with the wiring 310. When the cover 20 is closed, the main support part 31 bends along the recess 313. In addition, by providing the recess 313, the main support part 31 can be easily bent toward the extraction port 102, thereby enabling the cover 20 to move to the second open position.

[0032] Furthermore, both the upper end 322 and the lower end 321 are arc-shaped. The upper end 322 of the pair of side support parts 32 is generally an arc-shaped part that is concave to the lower side, and the lower end 321 of the pair of side support parts 32 is generally an arc-shaped part that is concave to the upper side. Specifically, the arc shape of the upper end 322 means that the side support part 32 and the upper side wall 21 include an upper edge line that is arc-shaped. At the same time, the arc shape of the lower end 321 means that the side support part 32 and the lower side wall 11 include a lower edge line that is arc-shaped. When the cover 20 moves from the first opening position to the second opening position, the main support... The support 31 moves inward and undergoes elastic deformation. At the same time, since both the upper end 322 and the lower end 321 are arc-shaped, the side support 32 also undergoes elastic deformation, making the side support 32 arc-shaped. This makes the entire connecting part 30 present a roughly spherical shape with a lower center and higher edges, making the entire structure more stable and thus keeping the cover 20 stable. In addition, when moving from the first opening position to the second opening position, the elastic deformation forms an auxiliary movement to accelerate the opening process of the cover 20. Similarly, when moving from the second opening position to the first opening position, the above-mentioned elastic deformation can also play an auxiliary movement to accelerate the closing process of the cover 20.

[0033] Furthermore, the side support portion 32 includes an outer end portion 3201 and an inner end portion 3202 adjacent to the main support portion 31. The thickness of the side support portion 32 gradually increases from the outer end portion 3201 to the inner end portion 3202 to prevent fatigue stress in the inner material of the side support portion 32.

[0034] Furthermore, the lower sidewall 11 includes a first surface 3200, and the lower end 321 of the side support 32 is connected to the first surface 3200. The first surface 3200 is an arc surface. The upper sidewall 21 includes a second surface 2100, and the upper end 322 of the side support 32 is connected to the second surface 2100. The second surface 2100 is also an arc surface. More specifically, the projection of the first surface 3200 on the substrate 101 is arc-shaped, and the projection of the second surface 2100 on the cover plate 201 is arc-shaped. When the first opening position moves to the second opening position, the main connecting part 30 moves inward, causing the upper sidewall 21 and the lower sidewall 11 to undergo elastic deformation, so as to further stabilize the support of the cover 20 and provide auxiliary movement force.

[0035] Furthermore, the lower sidewall 11 includes a waist-shaped hole 112. By setting the waist-shaped hole 112, the thickness of the lower sidewall 11 at the position where it is connected to the side support 32 is reduced, thereby making the corresponding position of the lower sidewall 11 more prone to elastic deformation. In this embodiment, the lower sidewall 11 includes a vertical piece 111, the side support 32 is connected to the vertical piece 111, and the waist-shaped hole 112 is located inside the vertical piece 111.

[0036] Furthermore, the cover 20, the base 10, and the connecting part 30 are integrally formed. More specifically, the cover 20, the base 10, and the connecting part 30 can be formed in one step by injection molding. It is understood that when injection molding, the cover 20, the base 10, and the connecting part 30 can be made of materials that are easy to injection mold, such as polypropylene or high-density polyethylene (HDPE).

[0037] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention.
