Description

A convenient-to-use flip-open lid assembly Technical Field

[0001] The present application relates to a packaging container, and in particular to a flip-open lid assembly that is easy to use. 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 applicant submitted a patent application on May 25, 2023, with application number 2023212962416, entitled "A Beverage Bottle Cap with a Pull-Open Structure." The rebuttal piece of the bottle cap extends downward, and there is no wrench portion or rebuttal piece extending outward on the bottle cap. This technical solution provides a circumferential folding groove on the plate, and the portion below the folding groove is a handle. When opening, the handle is folded outward along the folding groove, and then lifted upward to break the tear line and open the bottle cap. In the subsequent actual testing process, the applicant found that because the handle is small and can only be pinched by two fingers, a large force is required to break the tear line, making it inconvenient to open the bottle cap.

[0004] Therefore, this application is studied and proposed in response to the above problems. Application Contents

[0005] The purpose of this application is to overcome the shortcomings of the existing technology 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 flip the flip cover. It has the characteristics of easy operation, easy opening and low cost.

[0006] This application is achieved through the following technical solutions:

[0007] A convenient flip-open lid assembly comprises a lid base for connecting to a container mouth, a flip cover for opening or closing the container mouth being flipably connected to the lid base via a connecting piece; the flip cover is provided with a top-opening structure for causing the flip cover to flip relative to the lid base when the lid assembly moves relative to the container mouth; and / or the flip cover is provided with an opening plate extending toward a side of the lid base and flippable relative to the flip cover on a side away from the connecting piece, the opening plate being provided with a top-opening structure for causing the opening plate to flip outward relative to the flip cover when the lid assembly moves relative to the container mouth.

[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.

[0014] The flip cover is connected to the cover base via a tearable connection point / thin portion, and / or the opening plate is connected to the flip cover via a tearable connection point / thin portion.

[0015] A sealing plug is provided on the inner side of the flip cover, and a side of the sealing plug corresponding to the opening plate is provided with an avoidance slope, and / or a side of the sealing plug away from the opening plate is provided with a guide portion.

[0016] The flip cover and the cover base are connected via a destructible or tearable connecting tear line having an opening, and the opening of the connecting tear line forms the connecting piece.

[0017] The portion connecting the tear line openings is provided with two pairs of axial tearing portions, and the connecting piece is formed after the tearing portions are broken.

[0038] The following describes the implementation of the present application in detail with reference to Figures 1-14.

[0039] Embodiment 1, 3:

[0040] As shown in Figures 1-7 and 10-14, the present application 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 is rotated upward relative to the mouth of the container 100. When the user needs to operate the flip cover to flip open the container mouth, 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 container mouth. Therefore, the present application 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] As shown in Figures 11-14, two pairs of axial tearing portions 41 are provided at the opening of the connecting tear line 4. The connecting piece 11 is formed after the tearing portion 41 is broken. In this embodiment, there are four tearing portions 41, two on the left and two on the back. After the four tearing portions 41 are broken, two connecting pieces 11 are formed. 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] As shown in Figures 11-14, the opening plate 21 and the flip cover 2 are an integrally formed structure.

[0047] As shown in Figures 1-7 and 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 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 this application is the same as the opening structure 3 of the opening plate 21, and will not be repeated here.

[0048] As shown in Figures 5 and 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, thereby preventing the opening lever from being pushed open during assembly.

[0049] As shown in Figures 5 and 7, the inner upper surface of the plate thread section 31 is flat, which can facilitate the plate thread section 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] As shown in Figures 11-14, 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 portion of the connecting tear line 4, the flip cover forms an opening plate that opens outward at the location 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] As shown in Figure 1, 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 opening, the plate 21 is bent 20-130 degrees along the folding groove 211.

[0053] As shown in FIG1 , the flip cover 2 is connected to the cover base 1 via a tearable connection point / thin portion 22 , and / or the opening plate 21 is connected to the flip cover 2 via a tearable connection point / thin portion 22 , which can prevent counterfeiting.

[0054] As shown in FIG2 and FIG3 , 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, as shown in Figures 8 and 9, the sealing plug 23 is provided with an avoidance slope 231 on the side corresponding to the opening plate 21, which facilitates the sealing plug 23 to be inserted into or removed from the container mouth.

[0056] As shown in Figures 8 and 9, 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 distal 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 the flip cover is not easily misaligned when it is closed. Either the avoidance slope 231 or the guide portion 232 can be provided, or both can be provided for better results.
