Technical Field
[0001] The utility model relates to a packaging container, in particular to a convenient-to-use flip-open cover assembly. Background Art
[0002] Currently, in flip-top bottle caps, a wrench protruding outward is provided on the flip cap for easy opening. When opening, the wrench needs to be pried upward to open the bottle cap. On the one hand, a large opening force is required, which is inconvenient to use. On the other hand, the mold structure of the protruding wrench is relatively complex, which increases the difficulty of injection molding and leads to higher manufacturing costs of the bottle cap.
[0003] In addition, the inventor of the present invention submitted a patent utility model on May 25, 2023. The utility model number is 2023212962416, and the name is a beverage bottle cap with a pull-open structure. The rebuttal piece of the bottle cap extends downward, and there is no wrench part and rebuttal piece extending outward on the bottle cap. This technical solution is provided with a circumferential folding groove on the plate, and the part below the folding groove is a handle. When opening, the handle is folded outward along the folding groove, and then the handle is lifted upward to break the tear line and open. In the subsequent actual testing process, the inventor of the present invention found that because the handle is small and can only be pinched by two fingers, it requires a lot of force to break the tear line, which makes it inconvenient to open the bottle cap.
[0004] For this reason, the present invention is studied and proposed in view of the above problems. Utility Model Content
[0005] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an easy-to-use flip-open lid assembly. By providing a top-opening structure on the opening plate, the operating lid assembly can be moved relative to the container mouth to cause the opening plate to flip outward relative to the flip cover, thereby making it easy for the user to operate the opening plate to cause the flip cover to flip. The utility model has the characteristics of convenient operation, easy opening and low cost.
[0006] The utility model is realized through the following technical solutions:

[0008] The cover assembly is connected to the container mouth through a thread, and the opening plate is provided with a top opening structure for causing the opening plate to flip outward relative to the flip cover when the cover assembly rotates upward relative to the container mouth.
[0009] The top opening structure includes a plate thread section arranged on the inner wall of the opening plate, and the plate thread section is provided with a top opening protrusion which is used to overlap with the external thread on the container mouth when the cover assembly is rotated upward relative to the container mouth to cause the opening plate to flip outward relative to the flip cover.
[0010] The upper surface of the plate thread section is lower than the upper surface of the internal thread of the cover assembly. The inner surface of the plate thread section is flat.
[0011] The top opening structure is a top opening protrusion provided on the flip cover and / or the opening plate and used to cooperate with the container protrusion on the container mouth.
[0012] The inner side of the cover seat is provided with a locking protrusion for locking into the limiting groove of the container mouth.
[0013] A folding groove is provided between the upper end of the opening plate and the flip cover. The cross section of the folding groove is V-shaped.

[0038] The following is combined with Figure 1-14 The implementation methods of the present utility model are described in detail.
[0039] Embodiment 1, 3:
[0040] like Figure 1-7 As shown in Figures 10-14, the utility model provides an easy-to-use flip-open lid assembly, including a lid base 1 for connecting to the mouth of a container 100, and a flip cover 2 for opening or closing the mouth of the container 100 is flipably connected to the lid base 1 through a connecting member 11, and an opening plate 21 extending toward one side of the lid base 1 and flippable relative to the flip cover 2 is provided on the side of the flip cover 2 away from the connecting member 11, and the opening plate 21 is provided with a top-opening structure 3 for causing the opening plate 21 to flip outward relative to the flip cover 2 when the lid assembly moves relative to the mouth of the container 100; preferably, the lid assembly is connected to the mouth of the container 100 by a thread, and the opening plate 21 is provided with a top-opening structure 3 for causing the opening plate 21 to flip outward relative to the flip cover 2 when the lid assembly rotates upward relative to the mouth of the container 100. When the flip cover needs to be operated to flip open the mouth of the container, the user operates the lid assembly to rotate upward relative to the container mouth, so that the top-opening structure acts to flip the opening plate outward relative to the flip cover, that is, an operating space is formed between the opening plate and the flip cover for the user's hand to enter to operate the opening plate. Then, the user operates the opening plate to cause the flip cover to flip relative to the cover base to open the mouth of the container. Therefore, the utility model has the characteristics of convenient operation, easy opening, labor saving and low cost.
[0041] When the cover assembly is rotated upward relative to the container mouth until it can no longer move upward, on the one hand, the sealing plug is partially or completely disengaged from the container mouth (if the container contains a gas beverage, it may start to deflate), and on the other hand, the plate thread section 31 and the top opening protrusion 32 are disengaged from the external thread of the container mouth and are not affected by the external thread. In this way, when opening the flip cover, the opening plate 21 is almost free of resistance, and it is relatively easy for consumers to open the opening plate 21 and tear off the flip cover.
[0042] Among them, when the cover assembly on the mouth of the container 100 is screwed down, the upper part of the screw thread inside the cover assembly contacts the lower part of the screw thread outside the mouth of the container 100. Because the screw thread is inclined, the screw thread of the cover assembly will be gradually squeezed down by the screw thread of the mouth of the container 100, causing downward rotation; in addition, when the cover assembly is screwed down, the lower part of the screw thread inside the cover assembly is disengaged from the upper part of the screw thread outside the mouth of the container 100, that is, there is a gap.
[0043] When the cap assembly that is covered on the mouth of the container 100 needs to be unscrewed from the mouth of the container 100, the bottom of the screw thread inside the cap assembly contacts the top of the screw thread outside the mouth of the container 100. Because the screw thread is inclined, the screw thread of the cap assembly will be gradually pushed up by the screw thread of the mouth of the container 100, causing upward rotation; in addition, when the cap assembly is rotated upward, the top of the screw thread inside the cap assembly and the bottom of the screw thread outside the mouth of the container 100 are disengaged, that is, there is a gap.
[0044] To reduce assembly steps and mold costs, the lid base 1, connector 11, and flip cover 2 are integrally injection-molded from a material such as plastic. The flip cover 2 and lid base 1 are connected by a breakable or tearable connecting tear line with an opening. This connecting tear line can be a discontinuous notch or a thin-walled area. The connecting tear line can be located on the inside or outside of the lid assembly. When the lid is opened for the first time, the connecting tear line is torn or severed, and the area where the connecting tear line opens forms the connecting member 11.
[0045] like Figure 11-14 As shown, two pairs of axial tearing portions 41 are provided at the opening of the connecting tear line 4, and the connecting piece 11 is formed after the tearing portion 41 is broken. In this embodiment, four tearing portions 41 are provided, two on the left and two on the back. After the four tearing portions 41 are broken, two connecting pieces 11 are formed, and a breaking portion 42 is provided between the cover base 1 and the flip cover 2 between the two connecting pieces to facilitate rotation and opening.
[0046] like Figure 11-14 As shown, the opening plate 21 and the flip cover 2 are an integrally formed structure.
[0047] like Figure 1-7As shown in Figures 11-14, in order to better push open the opening plate, the opening structure 3 includes a plate thread section 31 provided on the inner wall of the opening plate 21. The plate thread section 31 is provided with a pushing protrusion 32 for pushing and overlapping with the external thread 110 on the mouth of the container 100 when the cover assembly is rotated upward relative to the mouth of the container 100, so as to cause the opening plate 21 to flip outward relative to the flip cover 2. During transportation or movement, the blocking cooperation between the opening protrusion and the external thread 110 can prevent the internal thread of the cover assembly from loosening due to bumps, ensuring that the cover assembly is in place before the consumer drinks and will not loosen or even be opened. The opening structure 3 of the flip cover 2 in the utility model is the same as the opening structure 3 of the opening plate 21, and will not be repeated here.
[0048] like Figure 5 As shown in Figure 7, the upper surface of the plate thread segment 31 is lower than the upper surface of the internal thread 20 of the cover assembly. In this way, when the cover assembly is screwed onto the container mouth, the plate thread segment will not be pushed by the external thread of the container mouth and will not be subjected to force, preventing the opening lever from being pushed open during assembly.
[0049] like Figure 5 As shown in FIG7 , the inner upper surface of the plate thread segment 31 is flat, which can facilitate the plate thread segment of the opening plate to overlap on the external thread of the container mouth, preventing the cover assembly from slipping, and also better pushing open the opening plate.
[0050] To provide another embodiment of a push-opening structure for easier opening, the push-opening structure 3 is a push-opening projection provided on the flip cover 2 and / or the opening plate 21 and configured to cooperate with a container projection at the mouth of the container 100. When the operating lid assembly is moved relative to the mouth of the container 100, the push-opening projection overlaps or abuts against the container projection, causing the opening plate to flip outward relative to the flip cover.
[0051] like Figure 11-14 As shown, the inner side of the lid base 1 is provided with a locking protrusion for locking into the limiting groove of the mouth of the container 100. The lid base 1 may or may not be provided with threads. If the lid base 1 is not provided with threads, the lid base 1 will not move upward when the lid assembly is rotated. If the lid base 1 is provided with threads, the locking protrusion is blocked by the limiting groove and will not move upward or will only move upward a very small distance. When the lid assembly is rotated to open, the locking protrusion of the lid base is blocked by the corresponding side wall of the limiting groove of the mouth of the container 100 and will not move upward or will only move upward a very small distance. However, the interaction between the threaded section (internal thread) of the flip cover and the external thread of the container mouth causes the flip cover to move upward a large distance, causing the connecting tear line 4 to break from the middle. Under the restraining force of the opening part of the connecting tear line 4, the flip cover forms an opening plate that opens outward at the part where the connecting tear line breaks. The flip cover can then be opened by pushing the opening plate upward. No additional wrench is required, which reduces the processing difficulty and makes opening easier.
[0052] like Figure 1 As shown, a folding groove 211 is provided between the upper end of the opening plate 21 and the flip cover 2. When the opening plate is pried outward from the lower end, the opening plate is bent along the folding groove 211, and the container is opened. The cross-section of the folding groove 211 is V-shaped. The angles of the two side surfaces of the folding groove 211 can limit the bending angle of the opening plate 21 along the folding groove 211. The inclination angles of the two side surfaces can be 10-65 degrees. When opened, the plate 21 is bent 20-130 degrees along the folding groove 211.
[0053] like Figure 1 As shown, the flip cover 2 and the cover base 1 are connected via a tearable connection point / thin portion 22, and / or the opening plate 21 and the flip cover 2 are connected via a tearable connection point / thin portion 22, which can play an anti-counterfeiting role.
[0054] like Figure 2 、 3 As shown, in order to improve the sealing performance, a sealing plug 23 is provided on the inner side of the flip cover 2. Example
[0055] The difference between Example 2 and Example 1 is that Figure 8 、 9 As shown, the sealing plug 23 is provided with an avoidance slope 231 on one side corresponding to the opening plate 21, and the avoidance slope 231 facilitates the sealing plug 23 to be inserted into or removed from the container mouth.
[0056] like Figure 8 、 9 As shown, the sealing plug 23 is provided with a guide portion 232 on the side away from the opening plate 21. When the flip cover is flipped nearly 90 degrees, the end of the guide portion 232 is already located above the container mouth. As the flip continues, the guide portion 232 first slides into the container mouth, ensuring that it is not easily misaligned when the flip cover is closed. Either the avoidance slope 231 or the guide portion 232 can be provided, or both can be provided for better results.
