Lid for container

Abstract

The lid for the container is formed so that the lid has a top plate and a circular side wall. Two opposing sides of the circular side wall are connected to each other in a circular shape, one outer edge of the circular side wall is connected to one surface of the top plate to form a closed end, and another outer edge of the circular side wall on the side opposite the closed end forms an open end. The circular side wall has a notch. The notch forms a ring member that is disposed at the open end of the lid and is separated from the body of the lid by a first notch and a second notch between the open end of the body and the ring member.

Description

[Technical Field]

[0001] FIELD OF THE INVENTION This application relates to lids for containers, and more particularly to lids that remain attached to a container after the container has been opened. The present application further relates to a corresponding method for providing a cap for a container. [Background technology]

[0002] Generally, lids for conventional containers are completely separated from their containers when the containers are opened. Therefore, the separated lids can easily fall off, be accidentally discarded, and / or be left behind / lost. Furthermore, when a separated lid is dropped, it can easily become soiled by contact with the ground or other uncontrolled surfaces, rendering the lid unusable. Furthermore, a discarded or misplaced / lost detached lid can contaminate the environment and cause further environmental problems. Therefore, to solve these problems, the industry has developed several lids that remain connected to the containers while the containers are in an open state. This prevents these lids from becoming separated from their containers, falling off, being accidentally discarded, being misplaced / lost, becoming soiled by contact with the ground or other uncontrolled surfaces, or potentially contaminating the environment or causing further environmental problems.

[0003] Nevertheless, existing lids with the above features may use complex designs and interlocking structures that require several difficult physical manipulations by the user to return the lid to its closed, sealed state. Manufacturing lids with these structures may also be complex or expensive. US Patent Application Publication No. 2019 / 344944 discloses a cap for a container according to the preamble of independent claim 1. SUMMARY OF THE INVENTION It is an object of the present application to provide an improved cap for a container and a corresponding method for providing a cap for a container. The object is solved with respect to the cap by the features of independent claim 1 and with respect to the method by the features of independent claim 8. Further embodiments are defined in the respective dependent claims. [Brief explanation of the drawings]

[0005] Figure 1 shows the container Lid1 shows a three-dimensional schematic diagram of a lid 10 of this example. As FIG. 1 shows, the lid 10 of this example includes a body 1 having a top plate 11 and a circular side wall 12. Two opposing sides of the circular side wall 12 are connected to each other in a circular shape. One outer edge of the circular side wall 12 is connected to one surface of the top plate 11, forming a closed end 1′. The other outer edge of the circular side wall 12, on the side opposite the closed end 1′, forms an open end 1″ (shown in FIG. 3). The lid 10 of this example also includes a ring member 2 disposed at the open end 1″ of the body 1. The ring member 2 is separated from the body 1 by a penetration line, which can be formed as part of the configuration of the lid 10. For example, the penetration line can be formed as part of the injection molding process or other manufacturing process by which the lid 10 is formed.

[0006] For example, the penetration line may also be formed by a cut. In the following description, the penetration line is often referred to as a cut line, but the penetration line can be formed by a method other than a cut. The ring member 2 is separated from the main body 1 by a first cut line 3 disposed between the open end 1'' of the main body 1 and the ring member 2. The first cut line 3 carries a plurality of connecting pins 31. The plurality of connecting pins 31 disposed along the first cut line 3 connect the main body 1 and the ring member 2 on both sides of the first cut line 3. The two ends of the first cut line 3 are separated by a plurality of connecting portions 5. The plurality of connecting portions 5 connect the main body 1 and the ring member 2. The plurality of second cut lines 4 are disposed on one side of the plurality of connecting portions 5. The plurality of second cut lines 4 are also disposed on either the main body 1 or the ring member 2. The two ends of the plurality of second cut lines 4 are not connected to themselves. The plurality of second score lines 4 do not overlap with the first score lines 3 .

[0007] As shown in FIG. 2A , in this example, the multiple connecting portions 5 are formed between the first incision line 3 and the multiple second incision lines 4. For example, the shape of the multiple connecting portions 5 is not particularly limited. The shape of the multiple connecting portions 5 depends on the shapes of the first incision line 3 and the multiple second incision lines 4 arranged on the sides of the multiple connecting portions 5. In this example, the shape of the multiple connecting portions 5 is a rectangular parallelepiped (shown in FIG. 3 ). For example, the number of the multiple connecting portions 5 is not particularly limited. However, in this example, the number of the multiple connecting portions 5 is two. For example, the spacing between each of the multiple connecting portions 5 is also not particularly limited. However, in this example, each of the multiple connecting portions 5 is separated by a portion of the multiple second incision lines 4.

[0008] For example, the number of the plurality of second cut lines 4 is not particularly limited. However, in this example, the number of the plurality of second cut lines 4 is two. As shown in FIG. 2A , only the main body 1 has the plurality of second cut lines 4. One of the two second cut lines 4 is connected to a portion of the first cut line 3. In addition, a portion of the plurality of second cut lines 4 is parallel to the first cut line 3.

[0009] For example, the first incision line 3 and the plurality of second incision lines 4 are not particularly limited. The first incision line 3 and the plurality of second incision lines 4 can each be, for example, a straight line, a curved line, a broken line, an arc line, or a combination thereof. In this example, the first incision line 3 is a straight line. The plurality of second incision lines 4 can also more preferably be an L-shaped line, an S-shaped line, a Z-shaped line, or a combination thereof. In this example, the plurality of second incision lines 4 are Z-shaped lines. For example, the corners 41 of the plurality of second incision lines 4 are not particularly limited. The corners 41 of the plurality of second incision lines 4 can be, for example, a curved corner, a chamfered corner, a sharp corner, or a combination thereof. In this example, the corners 41 of the plurality of second incision lines 4 are curved corners.

[0010] For example, the first score line 3 and the plurality of second score lines 4 may surround a portion of the circular side wall 12 or ring member 2, but may not completely surround the circular side wall 12 or ring member 2. The lengths of the first score line 3 and the plurality of second score lines 4, and the enclosed circular side wall 12 or ring member 2, are not particularly limited. In this example, the length of the first score line 3, and the enclosed circular side wall 12 or ring member 2, are longer than the respective lengths of the plurality of second score lines 4, and the enclosed circular side wall 12 or ring member 2. However, this can vary based on the embodiment.

[0011] 2B is a schematic diagram showing another embodiment of a lid for a container. The lid of this example is the same as the lid shown in FIG. 1 except that the plurality of second score lines 4 and the plurality of second score lines 4 shown in FIG. 2A are opposite each other. Nevertheless, the opening direction of the lid and the opening method of the lid shown in FIG. 2A are still the same (both are counterclockwise, i.e., rotation to the right in FIG. 2A or FIG. 2B).

[0012] 2C is a schematic diagram showing another embodiment of a lid for a container. The lid in this example is the same as the lid shown in FIG. 1 except that only the ring member 2 has the plurality of second score lines 4, and the plurality of second score lines 4 surround less than 1 / 5 of the ring member 2.

[0013] 2D is a schematic diagram showing another embodiment of a lid for a container. The lid in this example is the same as the lid shown in FIG. 1 except that the number of second score lines 4 is one, the second score line 4 extends from the main body 1 to the ring member 2 or from the ring member 2 to the main body 1, the second score line 4 and the first score line 3 are not connected, the corners 41 of the second score line 4 (Z-shaped lines) are sharp corners, and the second score line 4 surrounds less than 1 / 5 of the circular side wall 12 and less than 1 / 5 of the ring member 2.

[0014] Figure 2E is a schematic diagram showing another embodiment of a lid for a container, which is the same as the lid shown in Figure 1 except that the second score lines 4 are L-shaped lines and the corners 41 of these L-shaped lines are sharp corners.

[0015] Figure 2F is a schematic diagram showing another embodiment of a lid for a container, which is the same as the lid shown in Figure 1 except that the second score lines 4 and the first score lines 3 are not parallel to each other and the second score lines 4 are S-shaped lines.

[0016] 2G is a schematic diagram showing another embodiment of a lid for a container. The lid in this example is the same as the lid shown in FIG. 2E except that the corners 41 of the multiple second score lines 4 (L-shaped lines) are curved corners, and one of the second score lines 4 surrounds less than half of the circular side wall 12.

[0017] 3 is a three-dimensional schematic diagram showing an embodiment of a lid for a container separated from the container, where the lid shown could be any one of the lids in any one of the above examples. Below, a practical application of the lid is described in more detail using the lid shown in FIG.

[0018] For example, the provided lid 10 can be used with any conventional container without any particular limitation, as long as the lid 10 and the container 20 can be assembled together. For example, the shape of the lid 10 is not particularly limited. As shown in FIG. 3, the inside of the lid is circular. For example, the shape of the container 20 is similarly not particularly limited. As shown in FIG. 3, the opening 210 of the container is a circular opening. For example, the container 20 is a round bottle or a round can. As shown in FIG. 3, the container 20 is a bottle with a circular opening.

[0019] The body 1 of the lid 10 can control the opening and closing of the container opening 210. As shown in FIG. 3 , the inside of the body 1 has a screw thread 110. A complementary screw thread structure 2100 on the outside of the container opening 210 allows the body 1 to be twisted open (counterclockwise) and twisted closed (clockwise) (not shown) on the container opening 210 by rotation. For example, when the body 1 of the provided lid 10 is twisted closed on the container opening 210, the closed end 1′ of the body 1 abuts the container opening 210. Meanwhile, the open end 1″ of the body 1 faces the container opening 210 and fits over the container opening 210. As a result, the container opening 210 is closed, and the container 20 remains sealed.

[0020] For example, the exterior of the body 1 of the provided lid 10 may have notches 120. When the container 20 is opened, the notches 120 can rotate the body 1 and the ring member 2, making it easier to apply force to separate them. For example, depending on actual needs, the first score line 3 disposed between the body 1 and the ring member 2 of the provided lid 10 may have multiple connecting pins 31 to connect the body 1 and the ring member 2. The shape, size, number, and spacing of the multiple connecting pins 31 are not particularly limited. When the size and number of the multiple connecting pins 31 of the first score line 3 are smaller and the spacing between the multiple connecting pins 31 is larger, the force required to break the multiple connecting pins 31 is smaller. Conversely, when the size and number of the multiple connecting pins 31 of the first score line 3 are larger and the spacing between the multiple connecting pins 31 is smaller, the force required to break the multiple connecting pins 31 is larger. In this example, the size and number of the connecting pins 31 of the first score line 3 are smaller, and the spacing between the connecting pins 31 is larger. Furthermore, the second score lines 4 do not have the connecting pins 31. Therefore, the force required to break the connecting pins 31 is smaller. Therefore, the user can more easily separate the main body 1 and the ring member 2. That is, the lid 10 can be more easily opened from the opening 210 of the container.

[0021] For example, when the main body 1 of the lid 10 is twisted open from the container opening 210, the multiple connecting portions 5 connect the main body 1 and the ring member 2. The ring member 2 fits under the bulge 2200 of the container opening 210, and therefore the ring member 2 does not come off the container opening 210. As a result, the connection between the main body 1 and the ring member 2, even when separated from the container opening 210, allows the main body 1 to remain connected to the container 20. Furthermore, the multiple connecting portions 5 can also allow the main body 1 to remain open. The multiple connecting portions 5 prevent the main body 1 from interfering with the container opening 210. The multiple connecting portions 5 also reduce the free movement of the main body 1. As a result, when contents are dispensed from the container 20, the multiple connecting portions 5 can prevent the main body 1 from coming into contact with other objects due to its free movement. For example, if the container 20 is a water bottle, the multiple connecting portions 5 prevent the main body 1 from coming into contact with the user's face and any other body parts when the user is drinking from the water bottle. Furthermore, the multiple connecting parts 5 can also reduce the free movement of the main body 1, thereby preventing the remaining contents inside the main body 1 from spilling out easily. Also, the ring member 2 fitted into the opening 210 of the container can rotate freely, and therefore the multiple connecting parts 5 cannot be easily pulled out.

[0022] For example, the provided lid can be made using any material known in the art, where the material for the lid is, for example, plastic. The lid can be manufactured by any process known in the art. For example, the manufacturing process for the lid is an injection molding process. The first score line and the plurality of second score lines can be formed by any known method. In all the above examples, the first score line and the plurality of second score lines are formed by rotary cutting, and the cuts are made by a cutting tool or laser cutting.

[0023] Figure 4 shows a portion of a manufacturing system 70 used to cut a score line into a lid 73. The lid 73 is mounted on a spindle 71 and supported by a base 72. The lid 73 rotates as it passes a blade support structure 75 that holds a blade 76, as shown in Figure 5. The rotation of the lid 73 relative to the blade 76 cuts a score line into the lid 73.

[0024] FIG. 6 shows the spindle 71 mounted on the spindle support 76 .

[0025] FIG. 7 shows the path 121 that the lid 73 follows along the blade 76 to create the score lines in the lid 73 .

[0026] Figures 8, 9, 10, 11 and 12 show blade patterns for the blades used to score the lid.

[0027] FIG. 8 shows blade pattern 130, which uses blades 131, 132, and 133 to create score lines in lid 73, which serve as the connectors for attaching each lid to the ring portion. Blade 131 includes a first blade portion and a second blade portion that is disposed on a different plane than the first blade portion. The third blade portion forms a diagonal connector between the first and second blade portions. Similarly, blade 132 includes a first blade portion and a second blade portion that is disposed on a different plane than the first blade portion. The first blade portion is disposed on the same plane as first blade portion 131. The second blade portion is disposed on the same plane as second blade portion 131. The third blade portion forms a diagonal connector between the first and second blade portions. Blade 133 is disposed on the same plane as the first blade portion of blade 131. When the lid is attached to the container, the connection ensures that the lid remains attached to the container by its attachment to the ring, as described above, even after the lid is removed from the container opening. The notches in blades 131, 132, and 133 form a bridge connection between the lid and the ring portion. When the lid is attached to the container and the container is opened by twisting the lid off, the bridge connection is broken.

[0028] FIG. 9 shows blade pattern 140, which uses blades 141, 142, 143, 144, 145, 146, and 147 to create score lines in lid 73, which become the joints of each lid that attach the lid to the ring portion. Blades 141, 144, and 147 are all positioned on a first plane. Blades 143 and 146 are both positioned on a second plane. Blades 142 and 145 are both positioned on a third plane between the first and second planes. Blades 142 and 145 create smaller cuts than the other blades. Blades 142 and 145 are oriented diagonally between the first and second planes. Alternatively, blades 142 and 145 can be horizontal or vertical while positioned between the first and second planes.

[0029] When the lid is attached to the container, the connection ensures that the lid remains attached to the container by its attachment to the ring, as described above, even after the lid is removed from the container opening. The notches in blades 141, 143, 146, and 147 form a bridge connection between the lid and the ring portion. When the lid is attached to the container and the container is opened by twisting the lid off, the bridge connection is broken.

[0030] FIG. 10 shows blade pattern 150, which uses blades 151, 152, 153, 154, and 155 to create score lines in lid 73, which become the joints of each lid that attach the lid to the ring portion. Blade 151 is positioned on a first plane and has a first gap and a second gap. Blades 153 and 155 are both positioned on the second plane. Blades 152 and 154 are both positioned on a third plane between the first and second planes. Blade 152 is positioned near the first gap, and blade 154 is positioned near the second gap. Blades 152 and 154 create smaller cuts than the other would make in this configuration. Blades 152 and 154 are oriented diagonally between the first and second planes. Alternatively, blades 152 and 154 can be horizontal or vertical while positioned between the first and second planes. When the lid is attached to the container, the connection ensures that the lid remains attached to the container by its attachment to the ring, as described above, even after the lid is removed from the container opening. The notches in blades 151, 153, and 155 form a bridge connection between the lid and the ring portion. When the lid is attached to the container and the container is opened by twisting the lid off, the bridge connection is broken.

[0031] FIG. 11 shows blade pattern 160, which uses blades 161, 162, 163, 164, 165, 166, and 167 to create score lines in lid 73, which become the joints of each lid that attach the lid to the ring portion. Blades 163, 164, and 166 are all located on a first plane. Blades 165 and 167 are both located on a second plane. Blades 161 and 162 are both located on a third plane between the first and second planes. Blades 161 and 162 make smaller cuts than the other blades. Blades 161 and 162 are oriented diagonally between the first and second planes. Alternatively, blades 161 and 162 can be horizontal or vertical while located between the first and second planes. When the lid is attached to the container, the connection ensures that the lid remains attached to the container by its attachment to the ring, as described above, even after the lid is removed from the container opening. The notches in blades 163, 164, 165, 166, and 167 form a bridge connection between the lid and the ring portion. When the lid is attached to the container and the container is opened by twisting the lid off, the bridge connection is broken.

[0032] FIG. 12 shows blade pattern 170, which uses blades 171, 172, and 173 in a first plane. Blades 174 and 175 are disposed in a second plane. Blades 176 and 177 are oriented horizontally between the first and second planes. Alternatively, blades 176 and 177 can be oriented diagonally or vertically while disposed between the first and second planes. When the lid is attached to the container, the connection ensures that the lid remains attached to the container by its attachment to the ring, as described above, even after the lid is removed from the container opening. Notches in blades 163, 164, 165, 166, and 167 form a bridge connection between the lid and the ring portion. When the lid is attached to the container and the container is opened by twisting the lid off, the bridge connection is broken.

[0033] The spindle can include grooves that mirror the position of the blade to assist in cutting the score lines into the lid. For example, Figure 13 shows a spindle 180 having a spindle head 181 that includes grooves 182 that are wide enough to fit all the blade edges of the blade or blade pattern.

[0034] Figure 14 shows a spindle 200 having a spindle head 201 containing grooves 202 and 203, each wide enough to fit the blade edge of one of the blades or blade composites of the blade pattern. In the embodiment shown in Figure 14, each "horizontal" blade edge has its own matching groove, where there are no grooves for the vertical or angled blades or blade sections.

[0035] Figure 15 shows spindle 190 having spindle head 191 including grooves 192, 193, 194, and 195, each wide enough to fit the blade edge of one of the blades or blade sections, as represented by the blade edge of blade 196. In the embodiment shown in Figure 15, each "horizontal" blade has its own matching groove, and each vertical or diagonal blade or blade section has its own matching groove.

[0036] 16 shows spindle 290 with spindle head 294 including grooves 291, 292, and 293, each wide enough to fit one blade or one blade portion of the blade pattern. For example, blade combination 295 has blade edge 296, blade edge 297, and blade edge 298. For example, groove 292 is present to allow for beveled blades, such as beveled blades 152 and 154 shown in FIG. 10.

[0037] 17, 18, 19, 20, 21, 22, and 23 illustrate a lid 301 that can be retained in an inverted position relative to the container 300 after being removed from the container 300. In particular, FIG. 17 shows the lid 301 secured onto the container 300. First notch 303 and second notch 304 form coupling portions 305 and 306 between the lid 301 and the ring member 302. In the embodiment shown in FIG. 17, region 307 exists between the position where coupling portion 305 is coupled to the ring member 302 and the position where coupling portion 306 is coupled to the lid 301. The size of region 307, first notch 303, and second notch 304 all depend on the dimensioning of connecting portions 305 and 306 so that when lid 301 is removed from container 300, connecting portions 305 and 306 hold lid 301 in an inverted position relative to container 300, so the height of lid 301 and the diameter of lid 301 affect the length of region 307 and even whether region 307 is present.

[0038] In the inverted position, top surface 308 of lid 301 is held in a position where top surface 308 faces container 300. The lengths of connectors 305 and 306 are selected such that the elasticity of connectors 305 and 306 allows a user to move lid 301 into the inverted position relative to container 300 by stretching connectors 305 and 306, and then the elasticity of connectors 305 and 306 holds lid 301 in the inverted position relative to container 300 while the user drinks from the container.

[0039] Once the user has temporarily finished drinking from container 300, the resilience of coupling 305 and the resilience of coupling 306 allow the user to move lid 301 from the inverted position to the initial open position where the user can twist lid 301 back onto container 300. If the lid has a flip-top design, the lid may be reattached by placing it back onto the container.

[0040] 18 shows the lid 301 after it has been twisted off the container 300. Links 305 and 306 hold the lid 301 to the ring member 302. The top surface 308 of the lid 301 faces away from the container 300.

[0041] 19 shows a close-up view of lid 301 after it has been twisted off container 300. When lid 301 is removed, lip 310 of lid 301 is exposed. Links 305 and 306 hold lid 301 to ring member 302. Top surface 308 of lid 301 faces away from container 300.

[0042] 20 shows a close-up view of lid 301 after it has been pushed off of container 300. Links 305 and 306 hold lid 301 to ring member 302. Until sufficient force is applied to lid 301, links 305 and 306 are not long enough to invert lid 301 over lip 310 of container 300. Due to the short length of links 305 and 306, lip 310 prevents lid 301 from being placed in an inverted position with top surface 308 facing container 300. As the user applies more pressure, links 305 and 306 extend enough to invert lid 301 over lip 310, and lid 301 assumes the inverted position with top surface 308 facing container 300.

[0043] 21 and 22 show lid 301 in an inverted position with top surface 308 facing container 300. The resilience of connectors 305 and 306 holds lid 301 in the inverted position with top surface 308 facing container 300.

[0044] FIG. 23 is a top view illustrating that the resilience of connectors 305 and 306 holds lid 301 in an inverted position with top surface 308 facing container 300.

[0045] The height and diameter of the lid determine the length of the connection required to allow the lid to be placed and held in an inverted position with the top surface of the lid facing the container. Figures 24 and 25 show a container 400 with a lid 401 sized to fit over the lip 410 of the container 400.

[0046] 24 and 25 show the lid 401 being twisted open and pushed off the container 400. Links 405 and 406 hold the lid 401 to the ring member 402. Until sufficient force is applied to the lid 401, links 405 and 406 are not long enough to invert the lid 401 over the lip 410 of the container 400, the ring member 402, and the ridge 411 of the container 400. Due to the short length of links 405 and 406, the lip 410, the ring member 402, and the ridge 411 prevent the lid 401 from being placed in an inverted position with the top surface 408 facing the container 400. When the user applies further pressure, the connecting portions 405 and 406 stretch enough to invert the lid 401 over the lip 410, the ring member 402, and the ridge 411, and the lid 401 assumes an inverted position with the top surface 408 facing the container 400.

[0047] 26 shows the lid 401 in an inverted position with the top surface 408 facing the container 400. The resilience of the connecting portions 405 and 406 keeps the lid 401 in the inverted position with the top surface 408 facing the container 400.

[0048] FIG. 27 is a top view illustrating that the resilience of connectors 405 and 406 holds lid 401 in an inverted position with top surface 408 facing container 400.

[0049] The notches may be inverted. For example, FIG. 28 shows a lid 501 secured onto a container 500. First notch 503 and second notch 504 form coupling portions 505 and 506 between lid 501 and ring member 502. In the embodiment shown in FIG. 17, region 507 exists between the position where coupling portion 505 is coupled to ring member 502 and the position where coupling portion 506 is coupled to lid 501. The size of region 507, first notch 503, and second notch 504 all depend on dimensioning coupling portions 505 and 506 so that they can hold lid 501 in an inverted position relative to container 500 when lid 501 is removed from container 500, so the height and diameter of lid 501 affect the length of region 507 and even whether region 507 exists.

[0050] Slits can extend into the lid to make it easier to flip the lid to the inverted position. For example, Fig. 29 shows lid 601 on container 600. Fig. 30 shows lid 601 being twisted open and pushed off container 600. Linkage portion 605 and linkage portion 606 hold lid 601 to ring member 602. Slits forming connector portion 605 extend into lid 601. Slits forming connector portion 606 extend into lid 601.

[0051] Until enough force is applied to lid 601, links 605 and 606 are not long enough to invert lid 601 over container lip 610. As the user applies more pressure, links 605 and 606 stretch enough to invert lid 601 over the lip.

[0052] 31 shows the lid 601 in an inverted position with the upper surface 608 facing downward. The elasticity of the connecting portions 605 and 606 holds the lid 601 in the inverted position with the upper surface 608 facing downward. Due to the connecting positions of the connector portion 605 and the lid 601 at the bottom of the notch 612 and the connector portion 606 at the bottom of the notch 613, the connector portion 605 and the connector portion 606 do not stretch much to place the lid 601 in the inverted position. This means that placing the lid 601 in the inverted position requires less force and is therefore easier. Alternatively, the lid 601 can be placed in the inverted position with the upper surface 608 facing the container 600.

[0053] A tab extending from the lid can be added in a shape that holds the lid in an inverted position. For example, FIG. 32 shows a lid 701 having an upper surface 708 on a container 700. Two score lines delineate connector 705, connector 706, and tab 710, as shown. Tab 710 extends into gap 711 in ring member 702.

[0054] 33 shows the lid 701 being twisted open and pushed off the container 700. Links 705 and 706 hold the lid 701 to the ring member 702.

[0055] 34 shows the lid 701 in an inverted position with the top surface 708 facing downwards. The resilience of the connectors 705 and 706, as well as the shape and position of the tab 710, hold the lid 701 in the inverted position with the top surface 708 facing downwards.

[0056] FIG. 35 illustrates an improved cut pattern that simplifies manufacturing and improves operation. For example, FIG. 35 shows lid 801 on container 800. Lid 801 has top surface 808 and circular sidewall 813. Two cuts delineate connector 805, connector 806, tab 810, tab 812, and tab 816, as shown. The first cut includes cut portion 821, cut portion 822, cut portion 823, cut portion 824, cut portion 825, cut portion 826, and cut portion 827. The second cut includes cut portion 828, cut portion 829, cut portion 830, cut portion 831, cut portion 832, cut portion 833, and cut portion 834. Although the connecting pins are not specifically shown in FIG. 35, they may be included along the first and second notches as described above in other embodiments.

[0057] Link 805, link 806, tab 810, tab 812, and tab 816 are all formed between the same two cut surfaces. The first cut surface is represented by cut portions 821 and 827 of the first cut and by cut portions 828 and 832 of the second cut, which are all cut portions located on the first cut surface. The second cut surface is represented by cut portions 823 and 825 of the first cut and by cut portions 830 and 834 of the second cut, which are all cut portions located on the second cut surface.

[0058] The boundaries of the link 806 are defined by the notched portion 822 and the notched portion 823 of the first notch, and by the notched portion 828 and the notched portion 829 of the second notch.

[0059] The boundaries of the link 805 are defined by the notched portion 826 and the notched portion 827 of the first notch, and by the notched portion 833 and the notched portion 834 of the second notch.

[0060] The boundaries of tab 810 are defined by notch portion 829 of the second notch, notch portion 830, and notch portion 831. The boundaries of tab 812 are defined by notch portion 824 of the first notch, notch portion 825, and notch portion 826. The boundaries of tab 816 are defined by notch portion 832 of the second notch, notch portion 833, and notch portion 834.

[0061] The cut pattern shown in Figure 35 has several advantages over the cuts shown in Figure 32. For example, as shown in Figure 32, although connectors 705 and 706 are formed between two cut surfaces, tab 710 extends below these cut surfaces, requiring another plane of the blade that is used in the manufacture of lid 801.

[0062] This can be seen in Figure 9, which shows blades 141, 144, and 147 all disposed on a first plane, blades 143 and 146 both disposed on a second plane, and blades 142 and 145 both disposed on a third plane. Like the blade configuration shown in Figure 9, the cut pattern shown in Figure 32 requires blades to be placed in three different planes. However, the cut pattern shown in Figure 35 allows for the elimination of one of the planes of the blades, requiring only two of the planes of the blades.

[0063] Another benefit of the cut pattern can be seen by considering Figure 36, which shows lid 801 being twisted open and pushed off container 800. Links 805 and 806 hold lid 801 to ring member 802. Removal of tab 810 leaves gap 811 in ring member 802. Removal of tab 812 leaves gap 813 in ring member 802.

[0064] 36, both sides of link 806 extend from the second cut surface as depicted by cut portion 823 of the first cut and by cut portion 830 of the second cut. Similarly, both sides of link 805 extend from the second cut surface as depicted by cut portion 825 of the first cut and by cut portion 834 of the second cut.

[0065] However, in the cut pattern shown in Figure 33, the sides of connectors 705 and 706 extend from different cut planes, which results in aesthetics and optimal functionality of connectors 705 and 706. An optional feature is further illustrated in Figure 37.

[0066] FIG. 37 shows the lid 801 in an inverted position with the top surface 808 facing downward. In the inverted position, the tab 810 of the lid 801 is aligned to rest on the tab 816 of the ring member 802. The resilience of the connectors 805 and 806, as well as the shape and position of the tab 810, maintain the lid 801 in the inverted position with the top surface 808 facing downward. As shown in FIG. 37 , because both sides of the connector 806 extend from the second cut surfaces, the connector 806 can fold over and extend flat outward from the intersection region 814 of the ring member 802. Similarly, because both sides of the connector 805 extend from the second cut surfaces, the connector 805 can fold over and extend flat outward from the intersection region 815 of the ring member 802. Compare this to Figure 34, where the sides of link 706 extend from ring member 702 on two different cut planes, creating a looping effect where link 706 connects to ring member 702. Similarly, the sides of link 705 extend from ring member 702 on two different cut planes, creating a looping effect where link 705 connects to ring member 702. This twisting effect increases the effort required to remove and invert lid 701. This source of tension is eliminated, as achieved with the designs shown in Figures 35 and 37.

[0067] Another way to reduce tension when lifting lid 801 in the system shown in Figure 36 (e.g., by twisting it open) is for links 805 and 806 to be at parallel angles when lid 808 is lifted away from ring member 802. This feature of parallel angles for links 805 and 806 is also present in other embodiments shown, for example, in Figures 3, 18, and 33.

[0068] Additionally, because links 806 and 805 fold over and extend flat outward from ring member 802, this allows the width of the ring member to be reduced, lowering the position of inverted lid 801 relative to container 800. Thus, tab 810 can have a lower profile, as shown in Figure 37, compared to tab 710 shown in Figure 34. The reduced profile (i.e., lower height) of tab 810 allows for less tension on links 805 and 806 during inversion and uninversion, and allows links 806 and 805 to be shorter.

[0069] The cut pattern shown in Figure 35 allows for all of the above advantages, but similar cut patterns can also be used to achieve the same end result.

[0070] For example, FIG. 38 shows lid 841 on container 840. Lid 841 has top surface 848 and circular sidewall 843. Two notches delineate connector 845, connector 846, tab 865, tab 866, and tab 867, as shown. The first notch includes notch portion 851, notch portion 852, notch portion 853, notch portion 854, notch portion 855, notch portion 856, and notch portion 857. The second notch includes notch portion 858, notch portion 859, notch portion 860, notch portion 861, notch portion 862, notch portion 863, and notch portion 864. While connector pins are not specifically shown in FIG. 38 , they may be included along the first and second notches in other embodiments, as described above.

[0071] Link 845, link 846, tab 865, tab 866, and tab 867 are all formed between the same two cut surfaces. The first cut surface is represented by cut portion 851 and cut portion 855 of the first cut and by cut portion 858 and cut portion 862 of the second cut, which are all cut portions located on the first cut surface. The second cut surface is represented by cut portion 853 and cut portion 857 of the first cut and by cut portion 864 and cut portion 867 of the second cut, which are all cut portions located on the second cut surface.

[0072] The boundaries of the link 846 are defined by the notched portion 851 and the notched portion 852 of the first notch, and by the notched portion 863 and the notched portion 864 of the second notch.

[0073] The boundaries of the link 845 are defined by the notch portion 856 and the notch portion 857 of the first notch and the notch portion 858 and the notch portion 859 of the second notch.

[0074] The boundaries of tab 865 are defined by notch portion 861, notch portion 862, and notch portion 863 of the second notch. The boundaries of tab 866 are defined by notch portion 859, notch portion 860, and notch portion 861 of the second notch. The boundaries of tab 867 are defined by notch portion 852, notch portion 853, and notch portion 854 of the first notch.

[0075] In the inverted position, tab 865 of lid 841 is aligned to rest on tab 860 of ring member 842. In some embodiments, tab 867 can be eliminated by omitting notched portions 852, 853, and 854 and extending notched portion 851 to directly interface with notched portion 855.

[0076] In another example, FIG. 39 shows lid 871 on container 870. Lid 871 has top surface 878 and circular sidewall 873. Two notches delineate connector 875, connector 876, tab 895, tab 896, and tab 897, as shown. The first notch includes notch portion 881, notch portion 882, notch portion 883, notch portion 884, notch portion 885, and notch portion 886. The second notch includes notch portion 887, notch portion 888, notch portion 889, notch portion 890, and notch portion 891. While connector pins are not specifically shown in FIG. 39 , they may be included along the first and second notches in other embodiments, as described above.

[0077] Link 875, link 876, tab 895, tab 896, and tab 897 are all formed between the same two cut surfaces. The first cut surface is described by cut portion 881 of the first cut and by cut portion 887 of the second cut, which are all cut portions located on the first cut surface. The second cut surface is described by cut portion 883 and cut portion 886 of the first cut and by cut portion 891 of the second cut, which are all cut portions located on the second cut surface.

[0078] The boundaries of the link 876 are defined by the notched portion 881 and the notched portion 882 of the first notch, and by the notched portion 890 and the notched portion 891 of the second notch.

[0079] The boundaries of the link 875 are defined by the notch portion 885 and the notch portion 886 of the first notch and the notch portion 887 and the notch portion 888 of the second notch.

[0080] The boundaries of tab 895 are defined by notched portion 889 of the second notch and notched portion 890. The boundaries of tab 896 are defined by notched portion 888 of the second notch and notched portion 889. The boundaries of tab 897 are defined by notched portion 884 of the first notch and notched portion 885.

[0081] In the inverted position, tab 895 of lid 871 is aligned to rest on tab 896 of ring member 872. In some embodiments, tab 897 can be eliminated by omitting notched portions 884 and 885 and extending notched portion 883 to directly connect with notched portion 886.

[0082] In another example, FIG. 40 shows a lid 901 on a container 900. The lid 901 has a top surface 908 and a circular sidewall 903. Two cutouts delineate connector 905, connector 906, tab 925, tab 926, and tab 927, as shown. The first cutout includes cutout portion 911, cutout portion 912, cutout portion 913, cutout portion 914, cutout portion 915, and cutout portion 916. The second cutout includes cutout portion 920, cutout portion 918, cutout portion 919, cutout portion 920, cutout portion 921, and cutout portion 922. While connector pins are not specifically shown in FIG. 39 , they may be included along the first and second cutouts, as described above, in other embodiments.

[0083] Link 905, link 906, tab 925, tab 926, and tab 927 are all formed between the same two cut surfaces. The first cut surface is described by cut portion 911 of the first cut and by cut portion 917 of the second cut, which are all cut portions located on the first cut surface. The second cut surface is described by cut portions 913 and 916 of the first cut and by cut portions 919 and 922 of the second cut, which are all cut portions located on the second cut surface.

[0084] The boundaries of the link 906 are defined by the notched portions 911 and 912 of the first notch and by the notched portions 921 and 922 of the second notch.

[0085] The boundaries of the link 905 are defined by the notch portion 915 and the notch portion 916 of the first notch and the notch portion 917 and the notch portion 918 of the second notch.

[0086] The boundaries of tab 925 are defined by notch portion 920 and notch portion 921 of the second notch. The boundaries of tab 926 are defined by notch portion 918, notch portion 919, and notch portion 920 of the second notch. The boundaries of tab 927 are defined by notch portion 914 and notch portion 915 of the first notch.

[0087] In the inverted position, tab 925 of lid 901 is aligned to rest on tab 926 of ring member 902. In some embodiments, tab 927 can be eliminated by omitting notched portions 914 and 915 and extending notched portion 913 to directly connect with notched portion 916.

[0088] There are certain common features regarding the embodiments shown in Figures 35, 38, 39, and 40. For example, the tabs and all connections are formed between the first and second cut surfaces.

[0089] Additionally, both sides of the connectors extend to the base of the first cut surface. This is achieved by adding a cutout at the base of each connector that extends to the first cut surface. For example, in the embodiment shown in FIG. 35 , cutout 829 at the base of connector 806 extends from cutout 828 on the second cut surface to the first cut surface to interlock with cutout 830. Similarly, cutout 826 at the base of connector 805 extends from cutout 827 on the second cut surface to the first cut surface to interlock with cutout 825.

[0090] 38 , cutout portion 863 at the base of connecting portion 846 extends from cutout portion 864 on the second cutout surface to the first cutout surface to interlock with cutout portion 863. Similarly, cutout portion 856 at the base of connecting portion 845 extends from cutout portion 857 on the second cutout surface to the first cutout surface to interlock with cutout portion 855.

[0091] 39, cutout portion 890 at the base of link 876 extends from cutout portion 891 on the second cutout surface to the first cutout surface to interlock with cutout portion 889. Similarly, cutout portion 885 at the base of link 875 extends from cutout portion 886 on the second cutout surface to the first cutout surface to interlock with cutout portion 884.

[0092] 40, cutout portion 921 at the base of connector 906 extends from cutout portion 922 on the second cutout surface to the first cutout surface to connect with cutout portion 920. Similarly, cutout portion 915 at the base of connector 905 extends from cutout portion 916 on the second cutout surface to the first cutout surface to connect with cutout portion 914.
