DETAILED DESCRIPTION

FIG. 1 is an exploded view of a tamper-evident container 100 according to the first embodiment of the present disclosure. FIG. 2 is a three dimensional view of the tamper-evident container 100 of FIG. 1 after closing. In FIGS. 1 and 2, the tamper-evident container 100 includes a lid 110, a containing base, 120, and a release structure 130. The lid 110 is fixed to the containing base 120 for closing the containing base 120 and the release structure 130 is disposed at the containing base 120. The release structure 130 includes a barrier line 131 and two break lines 132. The break lines 132 are respectively extended from two ends of the barrier line 131 to the base edge 121. A detachable zone D1 is encompassed by the barrier line 131, the break lines 132, and the base edge 121. In addition, the containing base 120 includes a protrusion 122 extended from the base edge 121 within the detachable zone D1. The tamper-evident container 100 is integrally formed. The manner the lid 110 is fixed to the containing base 120 may be snapping, latching and so on.
FIG. 3 is a partial cross-sectional view of the tamper-evident container 100 taken along the line A-A of FIG. 2. In detail, the lid 110 has a lid edge 111 and the containing base 120 has a base edge 121. The base edge 121 encloses the lid edge 111 that makes the lid edge 111 hardly be held adequately. Therefore, the tamper-evident container 100 is almost unable to be opened after the lid 110 fixed to the containing base 120 unless by the release structure 130.
FIG. 4 is a schematic view showing the detachable zone D1 detached from the containing base 120 of the tamper-evident container 100 of FIG. 2. In FIG. 4, consumers detach the detachable zone D1 from the containing base 120 by pulling down the protrusion 122 to break the break lines 132, so that the lid edge 111 is partially exposed. The protrusion 122 facilitates breakage of the break lines 132 but may not be necessary. Once the lid edge 111 is partially exposed, consumers can hold the lid 110 and the containing base 120 adequately and separate them from each other. Therefore, the tamper-evident container 100 can be opened easily. The barrier line 131 is for stopping breakage of the break lines 132. In other words, the barrier line 131 is a terminal of the breakage of the break lines 132. The barrier line 131 may be a groove or other geometries.
Thus, there is no litter left but the lid 110 and the containing base 120 only when the tamper-evident container 100 is opened by the release structure 130. The tamper-evident container 100 would be more convenient to consumers and also environmentally-friendly. Moreover, the tamper-evident container 100 may be made of polylactic acid to further reduce the burden of environment.

In detail, the lid 210 has a lid edge 211 and the containing base 220 has a base edge 221. The lid edge 211 encloses the base edge 221 that makes the base edge 221 hardly be held adequately. Therefore, the tamper-evident container 200 is almost unable to be opened after the lid 210 fixed to the containing base 220 unless by the release structure 230.
FIG. 8 is a schematic view showing the detachable zone D2 detached from the lid 210 of the tamper-evident container 200 of FIG. 6. In FIG. 8, consumers detach the detachable zone D2 from the lid 210 by pulling up the protrusion 212 to break the break lines 232, so that the base edge 22 is partially exposed. The protrusion 212 facilitates breakage of the break lines 232 but may not be necessary. Once the base edge 221 is partially exposed, consumers can hold the lid 210 and the containing base 220 adequately and separate them from each other. Therefore, the tamper-evident container 200 can be opened easily. The barrier line 231 is for stopping breakage of the break lines 232. In other words, the barrier line 231 is a terminal of the breakage of the break lines 232. The barrier line 231 may be a groove or other geometries.
Thus, there is no litter left but the lid 210 and the containing base 220 only when the tamper-evident container 200 is opened by the release structure 230. The tamper-evident container 200 would be more convenient to consumers and also environmentally-friendly. Moreover, the tamper-evident container 200 may be made of polylactic acid to further reduce the burden of environment.

The release structure 330 is disposed at the containing base 320 and arranged in a non-overlapped manner with the hinge 340. The release structure 330 includes a barrier line 331 and two break lines 332. The break lines 332 are respectively extended from two ends of the barrier line 331 to the base edge 321. A detachable zone D3 is encompassed by the barrier line 331, the break lines 332, and the base edge 321. The manner the lid 310 is fixed to the containing base 320 may be snapping, latching and so on.
The lid 310 has a lid edge 311 and the containing base 320 has a base edge 321. Similarly, the base edge 321 encloses the lid edge 311 that makes lid edge 311 hardly be held adequately. Therefore, the tamper-evident container 300 is almost unable to be opened after the lid 310 fixed to the containing base 320 unless by the release structure 330.
As the first embodiment, the detachable zone D3 can be detached from the containing base 320 by pulling down the base edge 321 within the detachable zone D3 to break the break lines 332, so that the lid edge 311 can be partially exposed. Once the lid edge 311 is partially exposed, consumers can hold the lid 310 and the containing base 320 adequately and separate them from each other. Therefore, the tamper-evident container 300 can be opened easily. The barrier line 331 is for stopping breakage of the break lines 332. In other words, the barrier line 331 is a terminal of the breakage of the break lines 332. On the other hand, breakage of the break lines 332 does not damage the hinge 340 because the release structure 330 and the hinge 340 are arranged in a non-overlapped manner.
Thus, there is no litter left when the tamper-evident container 300 is opened by the release structure 330. The tamper-evident container 300 would be more convenient to consumers and also environmentally-friendly. Moreover, packaging goods by the tamper-evident container 300 with the hinge 340 is more efficient because packagers do not need to pick a lid and a containing base respectively during packaging process anymore.

The release structure 430 is disposed at the lid 410 and is arranged in a non-overlapped manner with the hinge 440. The release structure 430 includes a barrier line 431 and two break lines 432. The break lines 432 are respectively extended from two ends of the barrier line 431 to the lid edge 411. A detachable zone D4 is encompassed by the barrier line 431, the break lines 432, and the lid edge 411. The manner the lid 410 is fixed to the containing base 420 may be snapping, latching and so on.
The lid 410 has a lid edge 411 and the containing base 420 has a base edge 421. Similarly, the lid edge 411 encloses the base edge 421 that makes the base edge 421 hardly be held adequately. Therefore, the tamper-evident container 400 is almost unable to be opened after the lid 410 is fixed to the containing base 420 unless by the release structure 430.
As FIG. 10 shown, the detachable zone D4 can be detached from the lid 410 by pulling up the lid edge 411 within the detachable zone D4 to break the break lines 432, so that the base edge 421 is partially exposed. Once the base edge 421 is partially exposed, consumers can hold the lid 410 and the containing base 420 adequately and separate them from each other. Therefore, the tamper-evident container 400 can be opened easily. The barrier line 431 is for stopping breakage of the break lines 432. In other words, the barrier line 431 is a terminal of the breakage of the break lines 432. On the other hand, breakage of the break lines 432 does not damage the hinge 440 because the release structure 430 and the hinge 440 are arranged in a non-overlapped manner.
Thus, there is no litter left when the tamper-evident container 400 is opened by the release structure 430. The tamper-evident container 400 would be more convenient to consumers and also environmentally-friendly. Moreover, packaging goods by the tamper-evident container 400 with the hinge 440 is more efficient because packagers do not need to pick a lid and a containing base respectively during packaging process anymore.
