Description

[Technical field]

[0001] The present invention relates to a container with an anti-opening function, and more particularly to a container with an anti-opening function that is difficult to fall off, allows easy identification of the container as having been opened, and furthermore cannot be returned to its original unopened state after opening. [Background technology]

[0002] Currently, most of the various packaging containers used in food sections of supermarkets, restaurants, etc. are made of plastic or paper. Summary of the Invention [Problem to be solved by the invention]

[0003] However, some consumers selfishly open the outer packaging when selecting a product, causing the contents to deteriorate, and if other consumers cannot easily tell that the outer packaging has been opened, they may end up buying the food without noticing that a foreign object has been mixed in. Therefore, some stores put tape or stickers on the outer packaging to make it easier for other consumers to identify, in order to prevent selfish consumers from accidentally purchasing products that they have opened but left unpurchased.

[0004] On the other hand, even if the outer packaging has been opened by a selfish consumer, it can still be re-taped or sealed to make it appear as if it is still unopened. In addition, there are cases where the lid of the outer container is separated from the box body due to external forces being applied to the outer container during transportation of the food. In either of these cases, the freshness and safety of the product cannot be completely guaranteed. [Means for solving the problem]

[0005] In view of the above problems, the present invention has the following configuration.

[0006] In addition, the extension portion includes a folding piece that is connected to the second gripping piece and connected to the snap bottom portion via the dashed line, and when the first box body and the second box body are connected to each other, the folding piece is folded so that the snap bottom portion fits into the bottom surface of the second box.

[0007] The first snap portion includes a first side and a second side facing each other, the first gripping piece being located on the first side, and the second gripping piece being located on the second side. Further, the first peripheral wall portion includes a first peripheral wall portion main body and a first engagement surface, the second peripheral wall portion includes a second peripheral wall portion main body and a second engagement surface, the first engagement surface is located outside the periphery of the first peripheral wall portion main body, the second engagement surface is located outside the periphery of the second peripheral wall portion main body, and the first engagement surface is clipped to the second engagement surface, thereby determining the relative positions of the first box body and the second box body.

[0008] Additionally, the first snap portion includes a first neck portion and a first closure portion, the snap bottom portion includes a snap opening portion and a snap closure portion, the width of the neck portion is narrower than the width of the first closure portion, and the width of the snap opening portion is narrower than the width of the snap closure portion.

[0009] Also, the width of the snap closure is slightly greater than the width of the first neck. Additionally, the second snap portion includes a second opening and a second blocking portion, the width of the second opening being wider than the width of the second blocking portion, and the width of the first blocking portion being narrower than the width of the second blocking portion.

[0010] The first snap portion includes a first inner peripheral wall portion and a first outer peripheral wall portion, and the second snap portion further includes a second inner peripheral wall portion and a second outer peripheral wall portion, the first outer peripheral wall portion is formed to extend from the first inner peripheral wall portion in a direction away from the first main body portion, The second outer peripheral wall portion is formed to extend from the second inner peripheral wall portion in a direction away from the second main body portion, and when the first box bottom surface is overlapped on the second box bottom surface, the first outer peripheral wall portion abuts against the second outer peripheral wall portion.

[0011] Further, the first inner wall portion includes a guide portion, the guide portion is connected to the first neck portion, and the width of one end of the guide portion remote from the first blocking portion is wider than the width of the first neck portion. In addition, the snap bottom portion includes an anti-tamper strip and a snap opening, and the first box bottom further includes a first connecting surface, the anti-tamper strip is formed to extend outward from the snap opening, the first connecting surface is connected to the first locking surface, and the anti-tamper strip is substantially parallel to the first connecting surface and abuts against the first connecting surface. Effect of the Invention

[0012] As described above, the container with tamper-evident function of the present invention requires the user to pinch the first tab (grip) and the second tab and move them in opposite directions before opening. Also, when the container with tamper-evident function is opened, it breaks along the dashed line, the extension spreads in the direction away from the first box body, and the snap bottom part and the bottom of the first box, which are in close contact with each other, are both separated from the bottom of the second box. Therefore, the user can easily determine from the appearance whether the tamper-evident container has been opened just by looking at the tear marks, and can avoid troubles such as accidentally purchasing an already opened item or accidentally eating an opened item. In addition, it is possible to reduce disputes with consumers regarding whether the item has been opened or not. In addition, because the snap bottom part is fitted into the bottom of the first box, it will not easily open even if it receives an external impact during transportation, and from this perspective, it is also possible to prevent the contents from being opened by mistake.

[0016] [First embodiment] The present invention will be described with reference to Figures 1 to 3. The container 100 with an anti-tamper function of the present invention mainly includes a first box body 1 and a second box body 2. The first box body 1 and the second box body 2 have a storage space. Here, the first box body 1 and the second box body 2 are illustrated as being hollow rectangular parallelepipeds, but the present invention is not limited to such shapes, and may be shaped like a hollow circular box, a hollow oval box, or other polygonal shapes, and may be appropriately designed based on actual requirements.

[0017] In this embodiment, as shown in Fig. 1, the first box body 1 (lid body) is used to cover the second box body 2 (box body). Although the present invention is not limited to this, the second box body 2 can also cover the first box body 1. As shown in FIGS. 1 to 5, the first box 1 is mainly composed of a first main body portion 11, a first box bottom surface 12, and a first tab (first grip portion) 13.

[0018] The first main body portion 11 is mainly composed of a first base portion 111 and a first peripheral wall portion 112, the first peripheral wall portion 112 surrounding the first base portion 111 to form a storage space Q, and the first base portion 111 is substantially parallel to two horizontal planes P. As shown in Figures 2 and 3, the first box bottom surface 12 is formed to extend from an end corner of the first peripheral wall portion 112, but the present invention is not limited to this, and the first box bottom surface 12 may be formed to extend from a side edge of the first peripheral wall portion 112.

[0019] The first box bottom surface 12 includes a first snap portion 121. A direction Z2 in which the first snap portion 121 is recessed is substantially perpendicular to the horizontal plane P, that is, the direction Z2 in which the first snap portion 121 is recessed is substantially perpendicular to the first base portion 111.

[0020] 1, the first box bottom surfaces 12 are provided at the four end corners of the first box body 1, but the present invention is not limited thereto. The first box bottom surfaces 12 may be provided on the side edges of the first box body 1, and the present invention does not limit the number of first box bottom surfaces 12 provided. The first gripping piece 13 is formed to extend from the first peripheral wall portion 112, and as shown in FIG. 2, the first gripping piece 13 may extend from an end corner of the first peripheral wall portion 112 and is parallel to the first base portion 111 of the first main body portion 11; however, the present invention is not limited to this, and the first gripping piece 13 can be provided based on actual requirements, and the first gripping piece 13 does not have to be parallel to the first base portion 111, for example.

[0021] As shown in FIGS. 2 and 3, the second box 2 is mainly composed of a second main body portion 21, a second box bottom surface 22, a second tab 23, an extension portion 24, and a snap bottom surface portion 25. The second main body portion 21 is mainly composed of a second base portion 211 and a second peripheral wall portion 212. The second peripheral wall portion 212 surrounds the second base portion 211 to form an accommodation space O. Here, the first base portion 111 and the second base portion 211 are provided to face each other. That is, the first base portion 111 and the second base portion 211 are substantially parallel to each other.

[0022] The second box bottom surface 22 is formed to extend from an end corner of the second peripheral wall portion 212, but the present invention is not limited thereto. The second box bottom surface 22 may be formed to extend from a side edge of the second peripheral wall portion 212, and the second box bottom surface 22 may include a second snap portion 221. The recessed direction Z2 of the second snap portion 221 is substantially perpendicular to the horizontal plane P. That is, the recessed direction Z2 of the second snap portion 221 is substantially perpendicular to the second base portion 211.

[0023] As shown in FIG. 1, the second box bottom surfaces 22 are provided at the four corners of the second box body 2, but the present invention is not limited to this, and the second box bottom surfaces 22 may be provided on the side edges of the second box body 2, and the present invention has no limit on the number of second box bottom surfaces 22 provided.

[0024] The second gripping piece 23 is formed to extend from the second peripheral wall portion 212, and as shown in FIG. 2, the second gripping piece 23 may extend from an end corner of the second peripheral wall portion 212 and is parallel to the second base portion 211. However, the present invention is not limited to this, and it is sufficient to provide the second gripping piece 23 based on actual requirements, for example, the second gripping piece 23 does not have to be parallel to the second base portion 211.

[0025] The description will be made with reference to Figures 3 and 6. Here, Figure 6 is a cross-sectional view taken along line AA in Figure 5, in which the extension 24 is formed to extend further from the extension of the second box bottom 22, and the snap bottom portion 25 is formed to extend from the extension 24 and connects to the extension 24 via the dashed line L. In other words, the snap bottom portion 25 is formed at one end of the extension 24 remote from the second main body portion 21.

[0026] The second box bottom 22, the extension 24, and the snap bottom 25 may be integrally formed, and the dashed line L is formed by pressing with a blade, so that the snap bottom 25 can be torn along the dashed line L and separated from the extension 24.

[0027] Here, the shape of the dashed line L may be a straight line (as shown in FIG. 3), but the present invention is not limited to this, and it is sufficient to determine the shape of the dashed line L based on actual requirements. For example, the shape of the dashed line L may be a substantially S-shape (as shown in FIG. 12). Description will be given with reference to Figures 6 to 8. When the first box body 1 and the second box body 2 are joined, the first box bottom surface 12 overlaps with the second box bottom surface 22 (shown in Figure 6). When the snap bottom surface portion 25 is fitted into the first box bottom surface 12 (shown in Figure 7), the first lid body 1 can prevent the container with opening prevention function 100 from coming off the second box body 2 even if the container with opening prevention function receives an external impact during transportation, and it is possible to prevent the container with opening prevention function 100 from being opened by an impact during transportation.

[0028] Here, the first box bottom surface 12 is merely overlapped on the second box bottom surface 22, in other words, the first box bottom surface 12 and the second box bottom surface 22 are not tightly joined. On the other hand, the snap bottom surface portion 25 and the first box bottom surface 12 are in a tightly joined relationship, that is, the snap bottom surface portion 25 and the first box bottom surface 12 are in close contact with each other. Therefore, the first box bottom surface 12 can be easily detached from the second box bottom surface 22, and the snap bottom surface portion 25 is not easily separated from the first box bottom surface 12.

[0029] As shown in Fig. 4, when a user pinches the first tab 13 and the second tab 23 and moves them in opposite directions (for example, the first tab 13 moves in the upward direction Z1 on the horizontal plane P, and the second tab 23 moves in the downward direction Z2 on the horizontal plane P), the broken line L is pulled and the broken line L breaks (as shown in Fig. 8), and the snap bottom part 25 and the first box bottom 12, which are closely assembled to each other, can be separated together from the second box bottom 22 (as shown in Fig. 9). At this time, the first box body 1 and the second box body 2 are separated, and the container 100 with the tamper-evident function is opened.

[0030] Furthermore, since the broken line L ruptures, the extension portion 24 cannot reconnect to the snap bottom portion 25 via the broken line L, and the extension portion 24 expands in a direction away from the first main body portion 11, so that the user can immediately tell that the container 100 with anti-opening function has already been opened.

[0031] 3 again. In this embodiment, the extension 24 further includes a bent piece 241, which is connected to the second tab 23. That is, the bent piece 241 is provided on one side of the second tab 23 and connected to the snap bottom part 25 via a dashed line L. When the first box body 1 and the second box body 2 are assembled together, the bent piece 241 is bent and the snap bottom part 25 is fitted into the bottom surface 22 of the second box.

[0032] 2 and 3, in this embodiment, the first snap portion 121 includes a first side portion 121a and a second side portion 121b facing each other. As shown in FIG. 4, when the first box body 1 and the second box body 2 are connected to each other, the first knob 13 is located at the first side portion 121, and the second knob 23 is located at the second side portion 121b. Therefore, it is convenient for a user to pinch the first knob 13 and the second knob 23 with both hands, respectively, and the first knob 13 can be moved in the opposite direction to the second knob 23.

[0033] 3, in this embodiment, the first circumferential wall portion 112 mainly includes a first circumferential wall portion 1121 and a first locking surface 1122. The first locking surface 1122 is located outside the periphery of the first circumferential wall portion main body 1121, and the first circumferential wall portion main body 1121 and the first locking surface 1122 may be integrally formed.

[0034] The second circumferential wall portion 212 mainly includes a second circumferential wall portion main body 2121 and a second locking surface 2122. The second locking surface 2122 is located outside the periphery of the second circumferential wall portion main body 2121, and the second circumferential wall portion main body 2121 and the second locking surface 2122 may be integrally formed. 6, when the first box body 1 and the second box body 2 are joined together, the first locking surface 1122 is locked (fitted) into the second locking surface 2122, thereby positioning the first box body 1 and the second box body 2. At this time, the first locking surface 1122 abuts against the second locking surface 2122 in a direction away from the center of the first box body 1, and the first locking surface 1122 is locked to the second locking surface 2122.

[0035] 7, the first snap part 121 may include a first neck part 1211 and a first closing part 1212. The first closing part 1212 is one closed side of the first snap part 121. A first inner peripheral wall part 1213 of the first snap part 121 surrounds the first closing part and has a generally hollow columnar shape.

[0036] The cross section of the first snap portion 121 in the concave direction Z2 has a shape that gradually expands from the first neck portion 1211 to the first closing portion 1212; in other words, the cross section of the first snap portion 121 in the concave direction Z2 has a substantially hourglass shape. The snap bottom portion 25 may include a snap opening 251 and a snap closing portion 252. Here, the snap bottom portion 25 may be a hollow cylinder, and the cross section of the snap bottom portion 25 in the concave direction Z2 has a shape that gradually expands from the snap opening 251 to the snap closing portion 252.

[0037] The width W1 of the first neck portion 1211 of the first snap portion 121 is narrower than the width W2 of the first closing portion 1212, and the width W3 of the snap opening 251 of the snap bottom portion 25 is narrower than the width W4 of the snap closing portion 252. Therefore, when the snap bottom portion 25 is fitted into the first snap portion 121, the closer the snap bottom portion 25 is to the snap closing portion 252, the more closely it adheres to the first snap portion 121, and the less likely the snap bottom portion 25 is to peel off from the first snap portion 121. Therefore, when the first box body 1 or a part of the first box body 1 is separated from the second box body 2, the snap bottom portion 25 can still maintain a connected state with the first snap portion 121.

[0038] In this embodiment, the width W4 of the snap closure 252 is slightly greater than the width W1 of the first neck portion 1211. Since the width W4 of the snap closure portion 252 of the snap bottom portion 25 is larger than the width W1 of the first neck portion 1211 of the first snap portion 121, after the snap bottom portion 25 is fitted into the first box bottom surface 12, the snap closure portion 252 is restricted in movement by the second neck portion 1211, and therefore it is not easy to leave the second hook groove 121 in the direction Z1 away from the first snap portion 121, so that the snap bottom portion 25 can be firmly connected to the first snap portion 121.

[0039] 9. As shown in this embodiment, the second snap portion 221 includes a second opening 2211 and a second closing portion 2212. The width W5 of the second opening 2211 is greater than the width W6 of the second closing portion 2212. Therefore, the cross section of the second snap portion 221 in the recessed direction Z2 has a shape that gradually narrows from the second opening portion 2211 to the second closing portion 2212.

[0040] In addition, the width W2 of the first closing portion 1212 of the first snap part 121 is narrower than the width W6 of the second closing portion 2212. Therefore, when the first box body 1 or a part of the first box body 1 is separated from the second box body 2, the first snap part 121 can be easily detached from the second snap part 221.

[0041] 8 and 9. As shown in various embodiments, the first snap portion 121 may further include a first inner peripheral wall portion 1213 and a first outer peripheral wall portion 1214. The first outer peripheral wall portion 1214 is formed to extend from the first inner peripheral wall portion 1213 in a direction away from the first main body portion 11, and the portion of the first outer peripheral wall portion 1214 along the recessed direction Z2 is not parallel to the first inner peripheral wall portion 1213.

[0042] The second snap portion 221 further includes a second inner circumferential wall portion 2213 and a second outer circumferential wall portion 2214. The second outer circumferential wall portion 2214 is formed to extend from the second inner circumferential wall portion 2213 in a direction away from the second main body portion 21, and a portion of the second outer circumferential wall portion 2214 along the recessed direction Z2 is approximately parallel to the second inner circumferential wall portion 2213.

[0043] Furthermore, since the first outer peripheral wall portion 1214 and the second outer peripheral wall portion 2214 are substantially parallel, when the first box bottom surface 12 is overlapped on the second box bottom surface 22, the first outer peripheral wall portion 1214 abuts against the second outer peripheral wall portion 2214, thereby determining the relative position when the first box bottom surface 12 is overlapped on the second box bottom surface 22.

[0044] 8 and 9. As shown in various embodiments, the first inner wall portion 1213 may include a guide portion 1213a. The guide portion 1213a is connected to the first neck portion 1211, and a width W7 of one end of the guide portion 1213a away from the first closing portion 1212 is wider than the width W1 of the first neck portion 1211.

[0045] In order to avoid the snap bottom portion 25 not being able to smoothly fit into the first snap portion 121, the guide portion 1213a guides the snap bottom portion 25 to first enter the first snap portion 121, and the user then applies force again to pass the snap bottom portion 25 through the first neck portion 1211, thereby fitting the snap bottom portion 25 into the first snap portion 121.

[0046] 7, in some embodiments, the snap bottom portion 25 may include a tamper-evident strip 253 and a snap opening 251. The first box bottom 12 further includes a first connecting surface 1215. The tamper-evident strip 253 is formed to extend outward from the snap opening 251.

[0047] The first connecting surface 1215 is connected to the first locking surface 1122 of the first peripheral wall portion 112. When the snap bottom surface portion 25 is fitted into the first snap portion 121, the snap bottom surface portion 25 is located in substantially the same plane as the first snap portion 121, and the anti-tamper piece 253 abuts against the first connecting surface 1215.

[0048] This prevents a user from separating the snap bottom portion 25 and the first snap portion 121 through the gap between the snap bottom portion 25 and the first snap portion 121, thereby preventing the first box body 1 and the second box body 2 from separating and opening the container 100 with opening prevention function.

[0049] [Second embodiment] The second embodiment will be described below, but the same components as those in the first embodiment will be given the same reference numerals and the description thereof will be omitted.

[0050] 10 and 11, the container 100 with an anti-opening function mainly includes a first box body 1 and a second box body 2. In the above-mentioned embodiment, the first box body 1 is used to cover the second box body 2 (as shown in FIG. 1), but in this embodiment, the second box body 2 is used to cover the first box body 1.

[0051] 11 to 13, the first box body 1 is mainly composed of a first main body portion 11, a first box bottom surface 12, and a first tab 13. The first main body portion 11 is mainly composed of a first base portion 111 and a first peripheral wall portion 12, the first peripheral wall portion 112 surrounding the first base portion 111 to form a storage space Q (not shown), and the first base portion 111 is substantially parallel to a horizontal plane P.

[0052] Description will be made with reference to Figures 14 and 15. Here, Figure 15 is a cross-sectional view taken along line BB in Figure 12, in which the first box bottom surface 12 is formed to extend from the first peripheral wall portion 112, and the first box bottom surface 12 includes a first snap portion 121. A direction Z2 in which the first snap portion 121 is recessed is substantially perpendicular to the horizontal plane P.

[0053] The first gripping piece 13 is formed so as to extend in a direction away from the first circumferential wall portion 112 . The second box body 2 is mainly composed of a second main body portion 21, a second box bottom surface 22, a second gripping piece 23, an extension portion 24, and a snap bottom surface portion 25. 13 and 14. The second main body portion 21 is mainly composed of a second base portion 211 and a second peripheral wall portion 212. The second peripheral wall portion 212 surrounds the second base portion 211 to form an accommodation space O.

[0054] 15 to 17 will be referred to. The second box bottom surface 22 is formed to extend from the second peripheral wall portion 212. The second box bottom surface 22 includes a second snap portion 221. A concave direction Z2 of the second snap portion 221 is substantially perpendicular to the horizontal plane P. As shown in FIG. 14, the second gripping piece 23 is formed so as to extend from the second circumferential wall portion 212 .

[0055] 15 to 17, the extension 24 is formed to extend from the bottom surface 22 of the second box, and the snap bottom surface portion 25 is formed to extend from the extension 24 and is connected to the extension 24 via the dashed line L. 15 to 17. When the first box body 1 and the second box body 2 are joined together, the first box bottom surface 12 is overlapped with the second box bottom surface 22 (as shown in FIG. 16), and the snap bottom surface portion 25 is fitted to the first box bottom surface 12 (as shown in FIG. 16).

[0056] As shown in Fig. 14, when a user pinches the first tab 13 and the second tab 23 and moves them in opposite directions (for example, by moving the first tab 13 in an upward direction Z1 on the horizontal plane P and the second tab 23 in a downward direction Z2 on the horizontal plane P), the broken line L is pulled and breaks (as shown in Fig. 17). Then, the snap bottom portion 25 and the first box bottom 12, which are in close contact with each other, can be detached together from the second box bottom 22. This allows the user to separate the first box body 1 and the second box body 2, and open the container 100 with an anti-opening function.

[0057] In this embodiment, the first tab 13 and the second tab 23 are not located on opposite sides of the first box bottom surface 12, but the first tab 13 is stacked above the second tab 23, as shown in FIG. In this embodiment, the first snap part 121 does not include a first neck part 1211 (see, for example, FIG. 8). As shown in FIG. 15 to FIG. 17, the first snap part 121 and the snap bottom part 25 are both hollow columns, and the cross sections of the first snap part 121 and the snap bottom part 25 in the concave direction Z2 each have a shape that gradually widens from the open end to the closed end.

[0058] As described above, the container 100 with an anti-tamper function of the present invention can be opened by a user by pinching the first tab 13 and the second tab 23 and moving them in opposite directions. Furthermore, at the same time that the container 100 with an anti-tamper function is opened, the broken line L breaks, the extension 24 spreads in a direction away from the first box 1, and the snap bottom part 25 and the first box bottom 12, which are in close contact with each other, are detached from the second box bottom 22 together.

[0059] Therefore, the user can easily tell at a glance whether the tamper-evident container 100 is unopened or opened, which prevents erroneous purchases and consumption, effectively reducing consumer troubles. Also, because the snap bottom portion 25 fits into the first box bottom surface 12, the problem of the tamper-evident container 100 easily opening even if it receives an external impact during transportation can be eliminated.

[0060] The technical contents of the present invention have been described above with reference to the preferred embodiments, but these do not limit the technical scope of the present invention. Those skilled in the art may make changes or modifications without departing from the spirit of the present invention, and the invention after these modifications or changes should also be included in the scope of the present invention. The scope of protection of the present invention is determined based on the claims. [Explanation of symbols]
