[0001] Embodiments of this disclosure relate to an opening device, and more particularly to an opening device for reclosable packaging. Background Technology

[0002] Some packaging (such as beverage boxes) has an opening device that is connected to the packaging via a dirt ring to determine whether the packaging has been opened. The opening device's cap is attached to the packaging via a connecting mechanism to prevent the cap from falling off after the packaging has been opened. Summary of the Invention

[0003] According to one aspect of this disclosure, an opening device for a package is provided, characterized by comprising: a base and a cap, the base having a tilting tube including a first protrusion, the cap being movably disposed on the tilting tube and including a rising ramp disposed on the inner side of the cap body and rising around the inner side of the cap body, the rising ramp being able to abut against the first protrusion; wherein, during the opening of the package, the cap rotates relative to the tilting tube, and under the abutment action of the rising ramp against the first protrusion, the rising ramp can move upward relative to the first protrusion, thereby opening the cap.

[0004] According to one aspect of this disclosure, the pouring tube is characterized in that: the pouring tube defines an opening having an axis.

[0005] According to one aspect of this disclosure, the tilting tube further includes a second protrusion, the upper and lower sides of which are chamfered.

[0006] According to one aspect of this disclosure, the cap comprises: a cap body, an opening sealing plate, and a snap-fit ​​protrusion, the opening sealing plate being disposed on the top of the cap body, wherein when the cap is not open, the opening sealing plate can cover the opening of the pouring tube, and the snap-fit ​​protrusion being disposed on the inner side of the cap body, wherein in the closed state of the cap, the snap-fit ​​protrusion abuts against the lower side of the second protrusion, thereby keeping the cap in the closed state.

[0007] According to one aspect of this disclosure, the cap rotates relative to the pouring tube during the initial opening of the package. Under the abutment of the rising ramp and the first protrusion, the rising ramp can move upward relative to the first protrusion, and the locking protrusion can move upward over the second protrusion through the chamfer, thereby opening the cap.

[0008] According to one aspect of this disclosure, the cap is characterized in that: when the cap is closed, the cap can be closed at any position, and the snap-fit ​​protrusion can move downward over the second protrusion via the chamfer, thereby closing the cap; when the cap is opened again, the cap can be opened at any position, and the snap-fit ​​protrusion can move upward over the second protrusion via the chamfer, thereby flipping the cap open.

[0009] According to one aspect of this disclosure, the rising ramp is disposed above the snap-fit ​​protrusion in the height direction of the cap; and the first protrusion is disposed above the second protrusion in the height direction of the pouring tube.

[0010] According to one aspect of this disclosure, the feature is that: during the initial opening of the package, after the cap rotates at a certain angle relative to the pouring tube, the rising ramp can move upward relative to the first protrusion under the abutment action of the rising ramp and the first protrusion, thereby allowing the cap to be flipped open.

[0011] According to one aspect of this disclosure, it is characterized by further comprising: an opening identification window, at least a portion of which is disposed on the cap; and an opening identification block disposed in the opening identification window and at least partially detachably connected to the opening identification window; wherein, during the initial opening of the package, during rotation of the cap relative to the pouring tube, the opening identification block is movable relative to the opening identification window.

[0012] According to one aspect of this disclosure, it further comprises: a connecting ring rotatably and circumferentially mounted on the pouring tube; a first association structure for connecting the cap and the connecting ring, wherein the first association structure can attach the cap to the base when the cap is open; and a second association structure for rotatably mounting the connecting ring on the pouring tube to prevent the connecting ring from detaching from the pouring tube.

[0013] According to one aspect of this disclosure, it is characterized by further comprising: when the cap is open, the cap can be rotated relative to the pouring tube through its connection with the connecting ring, and can be closed at any rotation angle.

[0014] According to one aspect of this disclosure, the cap has a bottom edge, the connecting ring has an upper edge, and the bottom edge of the cap is detachably connected to the upper edge of the connecting ring; wherein, during the initial opening of the package, when the cap rotates relative to the base, the cap moves upward relative to the pouring tube, so that the bottom edge of the cap separates from the upper edge of the connecting ring.

[0015] According to one aspect of this disclosure, the bottom edge of the cap separates from the upper edge of the connecting ring when the connecting ring is deformed.

[0016] According to one aspect of this disclosure, the first associated structure rotatably connects the cap to the connecting ring, and as the cap moves upward relative to the pouring tube, the cap flips relative to the connecting ring, thereby gradually exposing the opening.

[0017] According to one aspect of this disclosure, the pouring tube includes an upper pouring tube and a lower pouring tube, the cap is movably disposed on the upper pouring tube, and the connecting ring is rotatably and circumferentially mounted on the lower pouring tube.

[0018] According to one aspect of this disclosure, the base further has a flange disposed at the axial end of the lower portion of the pouring tube, the pouring tube extending along the axis away from the upper surface of the flange, the flange extending outward around the pouring tube away from the axis, the flange being used to connect the base to the packaging.

[0019] According to one aspect of this disclosure, it is characterized by further comprising: a limiting device protruding outward from the outside of the pouring tube; wherein, before the package is first opened, the limiting device is used to limit the relative position of the cap and the base to prevent the cap from rotating relative to the base.

[0020] According to one aspect of this disclosure, the limiting device can drive the opening recognition block to move relative to the opening recognition window when the cap and the base rotate relative to each other.

[0021] According to one aspect of this disclosure, the cap rotates relative to the base at an angle between 260° and 280° during the initial opening of the package.

[0022] According to one aspect of this disclosure, the cap and the connecting ring are manufactured by integral molding. Attached Figure Description

[0044] Various specific embodiments of the present disclosure will now be described with reference to the accompanying drawings, which form part of this specification. It should be understood that although terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "top," and "bottom," are used herein to describe various exemplary structural parts and elements, their use is merely for illustrative purposes and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed herein can be arranged in different orientations, these terms indicating direction are illustrative only and should not be considered limiting.

[0045] Figure 1A-1B This is a schematic diagram of an opening device 100 according to an embodiment of the present disclosure applied to a package 10, wherein... Figure 1A This is a schematic diagram of the first embodiment of the opening device of this application applied to the closed state of the packaging; Figure 1B This is a schematic diagram of the first embodiment of the opening device of this application applied to the open state of the packaging.

[0046] like Figure 1A-1BAs shown, the packaging 10 includes an opening device 100 and a packaging body 20. The opening device 100 is disposed on the top of the packaging body 20 (e.g., a beverage packaging box), surrounding and covering the outlet of the packaging 10 (not shown in the figure), and is used to open or close the outlet of the packaging 10. Those skilled in the art will understand that in some other embodiments, if the outlet is located in other parts of the packaging body 20, the opening device 100 can also be adaptively configured according to the outlet location.

[0047] Figure 2A-2B A perspective view of the first embodiment of the opening device in both the closed and open states; Figures 3A-3C The structure of the base of the opening device is shown; Figures 4A-4E The structure of the cap of the opening device is shown.

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

[0049] The opening device 100 also includes a first connecting structure 203 and a second connecting structure. The first connecting structure 203 is disposed on the outer upper edge of the connecting ring 204 and the outer lower edge of the cap 202. The first connecting structure 203 may be a connecting hinge integrally manufactured with the cap 202 and the connecting ring 204, such as a bow-tie hinge, for connecting the cap 202 and the connecting ring 204 together, and allowing the cap 202 to be flipped relative to the connecting ring 204 so that the cap 202 can be attached to the tilting tube 302 of the base 206 through the connecting ring 204. The second connecting structure includes a first part 352 of the second connecting structure (see...). Figures 3A-3B ) and the second related structure, part 442 (see Figure 4B-4C(and 4E), the first part 352 of the second associated structure is a protruding structure surrounding the lower part 306 of the pouring pipe, protruding outward from the outside of the lower part 306 of the pouring pipe; the second part 442 of the second associated structure is a protruding structure surrounding the inner side of the connecting ring 204, protruding inward from the inner side of the connecting ring 204, which can be several discontinuous protruding structures (see 4E). Figure 4E Alternatively, it can be a single, inwardly protruding structure. During installation, the second part 442 of the second associated structure abuts against the lower part 352 of the first associated structure, preventing the connecting ring 204 from moving upward relative to the pouring pipe 302 and disengaging, thereby rotatably mounting the connecting ring 204 onto the pouring pipe 302.

[0050] The cap 202 includes a cylindrical cap body 412 and an opening sealing plate 414. The opening sealing plate 414 is disposed on the top of the cap body 412. When the cap 202 is not open, the cap body 412 surrounds the periphery of the pouring pipe 302, so that the opening sealing plate 414 can cover the opening 312 of the pouring pipe 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 via the first associated structure 203, so that the opening sealing plate 414 no longer covers the opening 312 of the pouring tube 302 (see...). Figure 2B The cap body 412 has a bottom edge 415, and the connecting ring 204 has an upper edge 417. The bottom edge 415 and the upper edge 417 are connected together by several cap body anchor points 212 (see details). Figure 2A (Enlarged view of Part A). When the cap 202 flips or tends to flip relative to the connecting ring 204, several cap body anchor points 212 will break, allowing the bottom edge 415 of the cap to separate from the upper edge 417 of the connecting ring and move relative to it. Even when the cap 202 is stationary and the connecting ring 204 deforms, several cap body anchor points 212 will also break. For example, if someone attempts to pry the cap 202 and connecting ring 204 off the base 206 together with the cap 202 through the gap between the lower edge of the connecting ring 204 and the base 206 while the package 10 is unopened, the connecting ring 204 will deform first, causing the cap body anchor points 212 to break, and the bottom edge 415 of the cap to separate from the upper edge 417 of the connecting ring. This allows other users to identify that the package 10 has been attempted to be opened.

[0051] A recessed opening recognition window 416 is provided on the lower edge of the cap body 412 in the circumferential direction. The opening recognition window 416 is formed by recessing upward from the lower edge of the cap body 412. In the embodiments of this application, the opening recognition window 416 is generally rectangular, having a left edge, a right edge, and a top edge. The span of the opening recognition window 416 in the circumferential direction of the cap 202 is less than 90°, for example, 60°. In some other embodiments, the span of the opening recognition window 416 in the circumferential direction of the cap 202 may also be set to less than 45°, for example, 30°. The opening recognition window 416 includes an opening recognition block 418. The left and right edges 222, 224 and the top edge 223 of the opening recognition block 418 are connected to the left and right sides and the top edge of the opening recognition window 416. The connection is weakened to facilitate disconnection or tearing; for example, a V-shaped groove 421 is provided in the connection. The bottom edge 214 of the opening recognition block 418 and the top edge 417 of the connecting ring are connected together by several opening recognition window anchor points 216 (see details). Figure 2A (Enlarged view of part B) When the opening recognition window 416 flips or has a tendency to flip, several opening recognition window anchor points 216 may break.

[0052] like Figure 4B As shown, an opening identification block actuation part 452 is provided on the inner side of the opening identification block 418, which is formed by protruding radially inward from the inner side of the opening identification block 418 for a certain distance. A limiting device 314 is provided on the outer side of the upper part 304 of the pouring pipe 302 (see...). Figure 3A The limiting device 314 consists of two protruding structures that extend radially outward from the outer side of the upper part 304 of the pouring tube. The two protruding structures of the limiting device 314 have a limiting chamfer 315 in the horizontal direction to allow the opening identification block actuation 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 restrained between the two protruding structures of the limiting device 314 by the opening identification block actuation part 452, thereby keeping the cap 202 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] During the initial opening of the package 10, when the cap 202 and the base 206 have just begun to rotate relative to each other, before the cap 202 has risen relative to the base 206, the actuating part 452 of the opening identification block 418 contacts and presses against the limiting chamfer 315 of the limiting device 314. This causes the limiting device 314 to apply a radially outward force to the opening identification block 418. Under this force, the anchor point 216 of the opening identification window may break, causing the opening identification block 418 to separate from the connecting ring 204. The left and right edges 222, 224 of the opening identification block 418 and the left and right sides of the opening identification window 416 may also break, allowing the opening identification block 418 to flip relative to the opening identification window 416 around its upper edge 223. After the opening identification block 418 flips, the actuating part 452 of the opening identification block and the limiting device 314 no longer press against each other, so the opening identification block 418 and the limiting device 314 no longer interfere with each other, allowing the cap 202 to continue rotating relative to the base 206. Because the weakened connection around the opening identification block 418 breaks and the opening identification block 418 flips around its upper edge 223, this process is irreversible, thus informing the user that the package 10 has been opened.

[0054] like Figure 2A and Figure 4A As shown, the upper edge of the cap 202 is provided with a positioning part 232, which protrudes radially outward from the upper edge of the cap 202. In the circumferential direction of the cap 202, the positioning part 232 is disposed opposite to the opening recognition block 418, that is, the circumferential direction is approximately 180° apart. When the user pinches or touches the cap 202, he will subconsciously avoid the protruding structure of the positioning part 232 and hold the cap 202 between the positioning part 232 and the opening recognition block 418 in the circumferential direction, thereby preventing the user from accidentally touching the opening recognition block 418 and damaging it.

[0055] like 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 Figure 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 part B and Figure 4A The snap-fit ​​protrusion 434 of the cap 202 abuts against the lower side of the second protrusion 334 of the pouring pipe 302. The rising ramp 432 of the cap 202 and the first protrusion 332 of the pouring pipe 302 are separated by a certain rotation angle in the circumferential direction and do not abut against each other.

[0061] like Figure 5B As shown, when the package 10 is opened for the first time, the cap 202 is twisted, causing it to rotate relative to the base 206. The opening identification block actuating part 452 of the opening identification block 418 and the limiting device 314, which are two protruding structures, come into contact and press against each other. This causes the protruding structure of the limiting device 314 to apply a radially outward force to the opening identification block 418. Under this force, the opening identification window anchor point 216 may break, causing the opening identification block 418 to separate from the connecting ring 204. The left and right edges 222 and 224 of the opening identification block 418 also break against the left and right sides of the opening identification window 416 under this force, allowing the opening identification block 418 to flip around its upper edge 223 relative to the opening identification window 416. This process is irreversible, thus informing other users that the package 10 has been opened. In the embodiments of this application, the angle of rotation of the cap 202 from the initial twisting to the complete breakage and flipping of the opening identification block 418 is 5° to 10°.

[0062] like Figure 5C As shown, after the identification window 416 is flipped, the cap 202 is rotated until the rising ramp 432 of the cap 202 contacts (aggregates) the first protrusion 332 of the pouring pipe 302. At this time, the cap 202 has not yet risen relative to the pouring pipe 302.

[0063] like 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 recognition window 616 is disposed on the cap 202, the lower half of the opening recognition window 616 is disposed on the connecting ring 204, and the opening recognition block 618 is disposed in the opening recognition window 616. Before the first opening, the left and right edges of the opening recognition block 618 are weakly connected to the left and right edges of the upper and lower halves of the opening recognition window 616, respectively, and the lower edge of the opening recognition block 618 is weakly connected to the lower edge of the lower half of the opening recognition window 616 on the connecting ring 204. When the package 10 is opened for the first time, the cap 202 is twisted and rotates relative to the base 206. The weak connections on the left and right sides and the lower side of the opening recognition block 618 are broken, so that it flips relative to the opening recognition window 616 with the upper edge as the pivot, to inform the user that the package 10 has been opened.

[0067] As those skilled in the art will know, in the two embodiments of this application, the direction in which the opening identification block breaks or flips is not limited to flipping upwards. In some other embodiments, by setting weak connections or anchor points in different directions of the opening identification block, the opening identification block can also be set to flip to the left or right, or in the second embodiment of this application, the opening identification block can also be set to flip downwards.

[0068] Existing packaging opening devices use an anti-theft or anti-contamination ring connected to a cap at the bottom of the pouring tube. Rotation of the cap causes the cap to break off from the anti-theft ring, indicating that the packaging has been opened. With a fixed height for the opening device, the inventors of this application, through long-term experimentation and observation, discovered that a higher cap provides better force distribution during rotation and closure, allowing users to open the cap with less force under the same conditions. Therefore, the inventors of this application have incorporated the anti-theft ring as an opening recognition window on the cap. This window occupies only a small circumferential span at the bottom edge of the cap. By saving space occupied by the anti-theft ring in the vertical direction, the cap can be set higher, allowing users to open it with less force under the same conditions.

[0069] The inventors of this application have also discovered that existing packaging requires rotation to close the cap after initial opening. During rotation, the protruding structure must be aligned with the corresponding rising track to smoothly close the cap. Therefore, the inventors of this application have designed a chamfered snap-fit ​​structure (e.g., the chamfered corners 341 and 342 of the second protrusion 334 in this application, and the mating structure with the snap-fit ​​protrusion 434), allowing the cap to be closed by pressing regardless of the angle after initial opening. When the snap-fit ​​structure is engaged, a "click" sound is produced to indicate that the cap is closed, allowing the user to close the cap more quickly and conveniently. If the cap needs to be opened again, a certain opening force can be applied to the cap at any rotation angle to separate the snap-fit ​​structure, thus opening the cap again. Therefore, the snap-fit ​​structure of the opening device in this application allows the user to quickly and conveniently close or open the cap at any rotation angle through the snap-fit ​​structure's engagement and disengagement.
