[0044] Various specific embodiments of the present disclosure will be described below with reference to the accompanying drawings, which are incorporated in, and constitute a part of, this specification. It should be understood that, although terms indicating directions, such as "front", "back", "up", "down", "left", "right", "top", "bottom", etc. are used to describe various example structural parts and elements of the present disclosure, these terms are used herein only for the purpose of convenience of explanation, and are determined based on the example orientation shown in the accompanying drawings. Since the embodiments disclosed in the present disclosure can be arranged in different directions, these terms indicating directions are only for illustration and should not be considered as limiting.

[0045] Figures 1A-1B Schematic view of the opening device 100 according to one embodiment of the present disclosure applied on a package 10, wherein Figure 1A Schematic view of the opening device according to a first embodiment of the application in the closed position applied on a package; Figure 1B Schematic view of the opening device according to a first embodiment of the application in the open position applied on a package.

[0046] As Figures 1A-1BAs shown, the package 10 comprises an opening device 100 and a package body 20, the opening device 100 is arranged on the top of the package body 20 (for example, a beverage package box) and surrounds and covers an outlet arrangement (not shown in the figure) of the package 10, for opening or closing the outlet of the package 10. Those skilled in the art can understand that in some other embodiments, the opening device 100 can also be adaptively arranged according to the position of the outlet if the outlet is arranged at other parts of the package body 20.

[0047] Figures 2A-2B Perspective view of a first embodiment of the opening device in a closed state and an open state; Figures 3A-3C Structure of the base of the opening device is shown; Figures 4A-4E Structure of the cap of the opening device is shown.

[0048] As Figures 2A-2B , Figures 3A-3C and Figures 4A-4E shown, the opening device 100 comprises a cap 202, a connecting ring 204 and a base 206, the cap 202, the connecting ring 204 and the base 206 are made of plastic, and the cap 202 and the connecting ring 204 can be integrally formed by injection molding. The base 206 surrounds the outlet of the package 10 and has a pouring tube 302 and a flange 322 arranged at the axial lower end of the pouring tube 302, and the cap 202 is movably arranged on the pouring tube 302 of the base 206. The pouring tube 302 defines an opening 312 which can be arranged in fluid communication with the outlet of the package 10. The opening 312 has a central axis X, the pouring tube 302 extends along the central axis X away from the upper surface of the flange 322, the flange 322 surrounds the pouring tube 302 and extends away from the central axis X for connecting the base 206 to the package 10. The pouring tube 302 comprises a pouring tube upper portion 304 and a pouring tube lower portion 306, the cap 202 is movably arranged on the pouring tube upper portion 304, and the connecting ring 204 is rotatably and circumferentially mounted on the pouring tube lower portion 306.

[0049] The opening device 100 further comprises a first associated structure 203 and a second associated structure, the first associated structure 203 is arranged on the outer side of the connecting ring 204 and the outer side of the lower edge of the cap 202, the first associated structure 203 can be a connecting hinge integrally manufactured with the cap 202 and the connecting ring 204, for example, a bowtie type hinge, for connecting the cap 202 and the connecting ring 204 together and enabling the cap 202 to be flipped relative to the connecting ring 204, so that the cap 202 can be attached to the pouring tube 302 of the base 206 through the connecting ring 204. The second associated structure comprises a second associated structure first portion 352 (see Figures 3A-3B ) and a second associated structure second portion 442 (see Figures 4B-4CThe second associated structure first portion 352 is a protruding structure around the pouring tube lower portion 306, protruding outward from the outside of the pouring tube lower portion 306, and the second associated structure second portion 442 is a protruding structure around the inside of the connecting ring 204, protruding inward from the inside of the connecting ring 204, which can be a plurality of discontinuous protruding structures (see Figure 4E ), or a whole inward protruding structure. When installed, the second associated structure second portion 442 abuts below the second associated structure first portion 352, which can prevent the connecting ring 204 from moving upward relative to the pouring tube 302 and disengaging, so as to rotatably install the connecting ring 204 on the pouring tube 302.

[0050] The cap 202 comprises a cylindrical cap body 412 and an opening cover plate 414 arranged on the top of the cap body 412. When the cap 202 is not opened, the cap body 412 surrounds the periphery of the pouring tube 302, so that the opening cover plate 414 can cover the opening 312 of the pouring tube 302 (see Figure 2A ); when the cap 202 is opened, the cap body 412 can be flipped relative to the connecting ring 204 and the pouring tube 302 through the first associated structure 203, so that the opening cover plate 414 no longer covers the opening 312 of the pouring tube 302 (see Figure 2B ). The cap body 412 has a cap bottom edge 415, and the connecting ring 204 has a connecting ring upper edge 417, and the cap bottom edge 415 and the connecting ring upper edge 417 are connected together through a plurality of cap body anchor points 212 (see Figure 2A for enlarged view of part A). When the cap 202 is flipped or has a tendency to be flipped relative to the connecting ring 204, the cap body anchor points 212 will be broken, so that the cap bottom edge 415 and the connecting ring upper edge 417 can be separated and moved relatively. In the case that the cap 202 is not moved and the connecting ring 204 is deformed, the cap body anchor points 212 will also be broken. For example, in the case that the package 10 is not opened, if someone tries to use a tool to pry the cap 202 and the connecting ring 204 from the base 206 through the gap between the lower edge of the connecting ring 204 and the base 206, the connecting ring 204 will be deformed first, which will cause the cap body anchor points 212 to be broken and the cap bottom edge 415 and the connecting ring upper edge 417 to be separated. In this way, other users can identify that the package 10 has been tried to be opened.

[0051] The lower edge of the cap body 412 is provided with a recessed opening identification window 416 in the circumferential direction. The opening identification window 416 is recessed upward from the lower edge of the cap body 412 by a distance to form. In the embodiment of the present application, the opening identification window 416 is substantially rectangular, which has a left side edge, a right side edge and an upper side edge. The opening identification window 416 occupies a span of less than 90°, for example 60°, in the circumferential direction of the cap 202. In some other embodiments, the opening identification window 416 can also be arranged to occupy a span of less than 45°, for example 30°, in the circumferential direction of the cap 202. The opening identification window 416 is provided with an opening identification block 418. The left and right edges 222, 224 and the upper edge 223 of the opening identification block 418 are connected to the left and right side edges and the upper side edge of the opening identification window 416. The connected parts are subjected to weakening treatment to facilitate breaking or tearing, for example, a V-shaped groove 421 is arranged at the connected parts. The bottom edge 214 of the opening identification block 418 is connected to the upper edge 417 of the connecting ring through a plurality of opening identification window anchor points 216 (see the enlarged view of part B of Figure 2A Fig. 6). When the opening identification window 416 is turned over or has a tendency to turn over, the plurality of opening identification window anchor points 216 can be broken.

[0052] As shown in Figure 4B , the inner side of the opening identification block 418 is provided with an opening identification block actuating part 452, which is formed by protruding radially inward from the inner side surface of the opening identification block 418 by a distance. The pouring pipe 302 is provided with a limiting device 314 (see Figure 3A ) on the outer side surface of the pouring pipe upper portion 304. The limiting device 314 is two protruding structures, which are formed by protruding radially outward from the outer side surface of the pouring pipe upper portion 304 by a distance. The two protruding structures of the limiting device 314 are provided with a limiting chamfer 315 in the horizontal direction to facilitate the opening identification block actuating part 452 to pass over the limiting device 314. Before the package 10 is opened for the first time, the opening identification block 418 is limited between the two protruding structures of the limiting device 314 by the opening identification block actuating part 452, so that the cap 202 is kept in a relatively stable position relative to the base 206 to prevent the cap 202 from rotating relative to the base 206 before the package 10 is opened.

[0053] In the process of opening the package 10 for the first time, when the cap 202 and the base 206 are just relatively rotated, at this time the cap 202 has not been lifted relative to the base 206, the opening recognition block actuating portion 452 of the opening recognition block 418 is in contact with and pressed against the limiting chamfer 315 of the limiting device 314, so that the limiting device 314 exerts a radially outward force on the opening recognition block 418, the opening recognition window anchor point 216 can be broken under the action of the force to make the opening recognition block 418 separate from the connecting ring 204, the left and right edges 222, 224 of the opening recognition block 418 and the left and right sides of the opening recognition window 416 can also be broken to make the opening recognition block 418 can be flipped around its upper edge 223 relative to the opening recognition window 416. After the opening recognition block 418 is flipped, the opening recognition block actuating portion 452 is no longer pressed against the limiting device 314, so the opening recognition block 418 no longer interferes with the limiting device 314, so that the cap 202 can continue to rotate relative to the base 206. Since the weakened connection around the opening recognition block 418 is broken and the opening recognition block 418 is flipped around its upper edge 223, this process is irreversible, so it can inform the user that the package 10 has been opened.

[0054] As shown in Figure 2A and Figure 4A The upper edge of the cap 202 is provided with a positioning portion 232 which is formed by protruding radially outward from the upper edge of the cap 202. In the circumferential direction of the cap 202, the positioning portion 232 is arranged opposite to the opening recognition block 418, i.e. the circumferential directions are approximately 180° apart. When the user pinches or touches the cap 202, he will subconsciously avoid the protruding structure of the positioning portion 232 and hold the cap 202 at the position between the positioning portion 232 and the opening recognition block 418 in the circumferential direction, so as to prevent the user from accidentally touching the opening recognition block 418 and damaging the opening recognition block 418.

[0055] As shown in Figures 3A-4EAs shown, the opening device 100 also includes a rising drive structure, which comprises two parts, respectively disposed on the cap 202 and the tilting tube 302. One part of the rising drive structure is a rising ramp 432, which is disposed on the inner side 431 of the cap body 412, protruding inward from the inner side 431 of the cap body, and rising around the inner side 431 of the cap body for a certain distance to form a rising track, thereby forming part of the structure of the cap body 412. The other part of the rising drive structure is a first protrusion 332 disposed on the outer side of the tilting tube 302, which protrudes outward from the outer side of the tilting tube 302, thereby forming part of the structure of the tilting tube 302. The first protrusion 332 extends horizontally for a certain distance in the circumferential direction on the outer side of the tilting tube 302, and one side of the first protrusion 332 is provided with a protrusion angle 333, for example, on the left side as in the embodiment of this application. The tilt angle of the protrusion 333 is the same as the tilt angle of the rising ramp 432, so that the first protrusion 332 can abut against the rising ramp 432 of the cap 202. During the initial opening of the package 10, when the cap 202 rotates relative to the pouring tube 302, under the abutment action of the rising ramp 432 and the first protrusion 332, the rising ramp 432 can move upward relative to the first protrusion 332 through the driving action of its rising track, so that the cap 202 moves upward relative to the pouring tube 302 while rotating. Since the first connecting structure 203 connects the cap 202 and the connecting ring 204 together, and the second connecting structure prevents the connecting ring 204 from moving upward relative to the pouring tube 302, during the upward rotation of the cap 202, the connecting ring 204 rotates synchronously with the cap 202 but does not move upward, causing the cap 202 to flip relative to the connecting ring 204 about the first connecting structure 203 as the axis of rotation. Several cap body anchor points 212 break when the cap 202 flips, so that the bottom edge 415 of the cap separates from the upper edge 417 of the connecting ring, which helps to open the cap 202 and gradually expose the opening 312.

[0056] Continue as Figures 3A-4E As shown, the pouring pipe 302 is also provided with several second protrusions 334, which are formed by protruding outward from the outside of the pouring pipe 302 and extending horizontally for a distance in the circumferential direction on the outside of the pouring pipe 302. See also Figure 3C Several second protrusions 334, first protrusions 332, and two protrusion structures of the limiting device 314 are staggered in the circumferential direction on the outside of the pouring pipe 302; in the embodiment of this application, there are three second protrusions 334, which are evenly distributed in the circumferential direction on the outside of the pouring pipe 302. In the height direction of the pouring pipe 302, the first protrusion 332 is disposed above the second protrusions 334, and the second protrusion 334 is disposed above the limiting device 314 (see...). Figure 3A The second protrusion 334 has chamfers 341 and 342 on its upper and lower sides respectively (see...). Figure 3B ).

[0057] like Figures 4B-4D As shown, the inner side 431 of the cap body 202 is also provided with a snap-fit ​​protrusion 434, which protrudes inward from the inner side 431 of the cap body and extends horizontally a certain distance in the circumferential direction of the inner side 431 of the cap body, thus forming part of the structure of the cap 202. In the height direction of the cap 202, an ascending ramp 432 is provided above the snap-fit ​​protrusion 434 (see...). Figure 4D (Perspective view). When the cap 202 is closed, the snap-fit ​​protrusion 434 of the cap 202 abuts against the underside of the second protrusion 334 of the pouring tube 302, thereby keeping the cap 202 in the closed state.

[0058] During the initial opening of the package 10, after the cap 202 rotates at a certain angle relative to the pouring tube 302, the rising ramp 432 begins to abut against the first protrusion 332. Under the abutment action of the rising ramp 432 and the first protrusion 332, the rising ramp 432 can move upward relative to the first protrusion 332. The upward movement of the rising ramp 432 of the cap 202 causes the locking protrusion 434 to be deformed by mutual compression with the chamfer 342 on the lower side of the second protrusion 334, thus moving upward over the second protrusion 334, thereby flipping the cap 202 open. After the initial opening of the package 10, the cap 202 can rotate relative to the pouring tube 302 through the connection with the connecting ring 204, and the cap 202 can also be closed after rotating at any angle. By pressing the cap 202, the locking protrusion 434 is deformed by mutual compression with the chamfer 341 on the upper side of the second protrusion 334 and moves downward past the second protrusion 334, thereby closing the cap 202. When opening the cap 202 again, the cap 202 can be opened at any position (angle). The locking protrusion 434 of the cap 202 can be deformed by mutual compression with the chamfer 342 on the lower side of the second protrusion 334 and moves upward past the second protrusion 334, thereby opening the cap 202 again.

[0059] Figures 5A-5E The process of opening package 10 for the first time is shown.

[0060] like Figure 5A As shown, before the package 10 is opened for the first time, the opening device 100 is in a closed state. The opening identification block 418 is restricted between the two protruding structures of the limiting device 314 by the opening identification block actuation part 452, so that the cap 202 is kept in a stable position relative to the base 206 and is not easy to rotate. The bottom edge 415 of the cap body 412 and the upper edge 417 of the connecting ring 204 are connected together by several cap body anchor points 212 (see details). Figure 2A Enlarged view of part A and Figure 4A The bottom edge 214 of the opening recognition block 418 and the upper edge 417 of the connecting ring are connected together by several opening recognition window anchor points 216 (see details).Figure 2A enlarged view of B and Figure 4A ), the snap projection 434 of the cap 202 abuts under the second projection 334 of the pourer 302. The ascending ramp 432 of the cap 202 is circumferentially angularly spaced from the first projection 332 of the pourer 302 and does not abut.

[0061] As shown in Figure 5B the first time the package 10 is opened, the cap 202 is twisted to rotate relative to the base 206, the opening recognition block actuation portion 452 of the opening recognition block 418 contacts and is pressed by the two-projection structure of the stopper 314, so that the two-projection structure of the stopper 314 exerts a radially outward force on the opening recognition block 418, the opening recognition window anchor point 216 can be broken under the force to separate the opening recognition block 418 from the connecting ring 204, the left and right edges 222, 224 of the opening recognition block 418 are also broken under the force to separate the opening recognition block 418 from the left and right sides of the opening recognition window 416, so that the opening recognition block 418 can be flipped around the upper edge 223 relative to the opening recognition window 416, and this process is irreversible, thus informing other users that the package 10 has been opened. In the embodiment of the present application, the cap 202 is twisted from the initial twist to the complete breakage and flipping of the opening recognition block 418 by an angle of 5° to 10°.

[0062] As shown in Figure 5C after the opening recognition window 416 is flipped, the cap 202 is continuously twisted to rotate to the position where the ascending ramp 432 of the cap 202 contacts (abuts) the first projection 332 of the pourer 302, at this time the cap 202 has not yet ascended relative to the pourer 302.

[0063] As shown in Figure 5DAs shown, after the rising ramp 432 of the cap 202 contacts the first protrusion 332 of the pouring tube 302, the cap 202 continues to be rotated. Under the abutment of the rising ramp 432 and the first protrusion 332, the rising track of the rising ramp 432 slides relative to the first protrusion 332, allowing the cap 202 to rise relative to the pouring tube 302 during rotation. Since the cap 202 is connected to the connecting ring 204 through the first connecting structure 203, and the connecting ring 204 cannot move upward relative to the pouring tube 302 due to the obstruction of the second connecting structure, during the upward rotation and movement of the cap 202, the connecting ring 204 rotates synchronously with the cap 202 but does not move upward. This causes the cap 202 to initially flip relative to the connecting ring 204 with the first connecting structure 203 as the axis of rotation. At the same time, several cap body anchor points 212 break, causing the bottom edge 415 of the cap to separate relative to the upper edge 417 of the connecting ring, thus facilitating the opening of the cap 202. During the flipping process of the cap 202 relative to the connecting ring 204, the snap-fit ​​protrusion 434 of the cap 202 can be deformed by being squeezed by the chamfer 342 on the lower side of the second protrusion 334, and move upward past the second protrusion 334 of the tilting tube 302, so that the cap 202 can smoothly flip and move relative to the connecting ring 204, thereby gradually exposing the opening 312. At this time, the angle of rotation of the cap 202 from the initial twist to the completion of the initial rise is 260° to 280°. In the embodiment of this application, the angle of rotation of the cap 202 from the initial twist to the completion of the initial rise is 270°.

[0064] like Figure 5E As shown, after the cap 202 is fully rotated and raised through the rising track of the rising ramp 432, and the cap body anchor point 212 is completely broken, the cap 202 can be manually flipped to fully expose the opening 312 and complete the opening of the package 10. The flipping angle of the cap 202 is 135° to 170°.

[0065] Figures 6A-6D This is a schematic diagram of the second embodiment of the opening device in the closed state and after being turned at an angle from the closed state. The difference between the second embodiment and the first embodiment lies in the different positions of the opening recognition window and the opening recognition block; the similar parts will not be described again.

[0066] like Figures 6A-6DAs shown in the second embodiment, the upper half of the opening identification window 616 is arranged on the cap 202, the lower half of the opening identification window 616 is arranged on the connecting ring 204, and the opening identification block 618 is arranged in the opening identification window 616. Before the first opening, the left and right side edges of the opening identification block 618 are weakly connected with the left and right side edges of the upper and lower halves of the opening identification window 616 respectively, and the lower side edge of the opening identification block 618 is weakly connected with the lower side edge of the lower half of the opening identification window 616 on the connecting ring 204. When the packaging 10 is opened for the first time, the cap 202 is twisted to rotate relative to the base 206, and the weak connections of the left and right sides and the lower side of the opening identification block 618 are broken, so that the opening identification block 618 is flipped over relative to the opening identification window 616 with the upper edge as the rotating shaft, to inform the user that the packaging 10 has been opened.

[0067] As known by those skilled in the art, in the two embodiments of the present application, the direction of flipping of the opening identification block is not limited to upward flipping. In some other embodiments, by arranging weak connections or anchor points in different directions of the opening identification block, the opening identification block can also be arranged to flip leftward or rightward, or in the second embodiment of the present application, the opening identification block can also be arranged to flip downward.

[0068] The opening device of the existing packaging is arranged by setting a theft-proof ring or a pollution-proof ring connected with the cap at the bottom of the pouring pipe, and the cap is broken by rotating the cap to show that the packaging has been opened. Under the condition that the opening device of the packaging is fixed in height, the inventors of the present application have found through long-term experiments and observations that the higher the height of the cap, the better the stress condition when rotating and opening and closing, thereby facilitating the user to open the cap with smaller force under the same conditions. Therefore, the inventors of the present application arrange the structure of the theft-proof ring on the cap in the form of an opening identification window, which only occupies a small circumferential span at the bottom edge of the cap. Since the space occupied by the theft-proof ring in the height direction is saved, the height of the cap can be arranged higher, thereby facilitating the user to open the cap with smaller force under the same conditions.

[0069] The inventor of the present application also found that the existing packaging needs to be closed by rotating the cap after the first opening. When rotating, the protruding structure needs to be aligned with the corresponding raised track to smoothly rotate the cap. Therefore, the inventor of the present application designs a chamfered clamping structure (for example, the chamfered 341, 342 of the second protrusion 334 in the present application and the matching structure of the clamping protrusion 434) to make the cap be closed by pressing after the first opening, regardless of the angle of rotation. When the clamping structure is clamped and fixed, a "click" sound will be produced to indicate the completion of the closing action of the cap, so that the user can more quickly and conveniently close the cap. If you need to open the cap again, you can apply a certain opening force to the cap at any rotation angle of the cap, so that the above-mentioned clamping structure is separated, thereby opening the cap again. Therefore, the clamping structure of the opening device in the present application makes the user can quickly and conveniently close or open the cap by clamping and separating the clamping structure at any rotation angle of the cap.
