[0019] The detailed description and technical content of the present invention will be described below with reference to the drawings. However, the attached drawings are shown only for the purpose of explanation and do not limit the present invention.
[0020] The present invention relates to a slide frame lock type sealed box for hermetically storing articles that require freshness retention or moisture prevention, such as foods and medicinal materials. Referring to FIGS. 1 to 3, the slide frame lock type sealed box of the present invention mainly includes a box body 10, an upper lid 20, and a pair of slide frames 30.
[0021] First, referring to Figures 1 and 2, the box body 10 includes a bottom plate 11 and a surrounding wall 12 that encloses the bottom plate 11. In this embodiment, the bottom plate 11 is generally rectangular in shape, but the present invention is not limited thereto, and the bottom plate 11 may be, for example, square, circular, or elliptical. The surrounding wall 12 is provided so as to enclose the bottom plate 11 and forms a housing space (not indicated by reference numerals) and an opening 13 that communicate with each other. The surrounding wall 12 is provided with a flange 14 that extends to the outside of the box body 10 at the opening 13. In this embodiment, the flange 14 is generally rectangular in shape, corresponding to the bottom plate 11 and the surrounding wall 12. A first fixing structure 15 is provided on each of the opposing sides of the flange 14. Specifically, in this embodiment, the first fixing structure 15 is provided on the long side of the flange 14. The specific structure of the first fixing structure 15 will be described later, so a detailed explanation is omitted here.
[0022] Referring to Figures 1 to 3, the outer shape of the top cover 20 corresponds to the outer shape of the bottom plate 11, and the top cover 20 in this embodiment is also roughly rectangular. The top cover 20 is positioned to cover the opening 13 of the enclosure wall 12 in a sealed state along the vertical direction D (i.e., the up and down direction in Figure 2). The top cover 20 has a pair of opposing first side frames 21 and a pair of opposing second side frames 22. In this embodiment, each first side frame 21 is positioned corresponding to the two long sides of the enclosure wall 12, and each second side frame 22 is positioned corresponding to the short side of the enclosure wall 12, but the present invention is not limited thereto. Each first side frame 21 has a pair of limiting portions 23. Each limiting portion 23 in each first side frame 21 is spaced apart from each other. Each limiting portion 23 includes a slot 231 and a limiting side cover 232. Specifically, in this embodiment, the slot 231 is formed on the upper part of the first side frame 21, and the limiting side cover 232 is formed on the outside of the first side frame 21. Between each limiting side cover 232 and the corresponding first side frame 21, a storage space is formed that can accommodate the insertion end 33, which will be described later (these are not labeled with reference numerals).
[0023] Referring again to Figures 1 to 3, each slide frame 30 is positioned opposite each other and corresponding to each second side frame 22. Each slide frame 30 includes a pair of side frames 31 and a connecting frame 32. Each connecting frame 32 is positioned corresponding to each second side frame 22. In each slide frame 30, each side frame 31 is connected to both ends of the connecting frame 32, and each side frame 31 covers a portion of each first side frame 21. Each slide frame 30 includes a pair of insertion ends 33, at least one second fixing structure 34, and at least one stopper plate 35. Each insertion end 33 is provided at the end of each side frame 31 away from the connecting frame 32. Each insertion end 33 has a positioning tab 331 extending along the first side frame 21. The specific structure and position of the second fixing structure 34 and the stopper plate 35 will be described later, so a detailed explanation is omitted here.
[0024] Referring to Figures 4 and 10, each slide frame 30 slides along each first side frame 21 and is switchable between a locked position and an unlocked position. Referring to Figures 4 to 9, when each slide frame 30 is in the locked position, each positioning tab 331 is inserted into and locked in each slot 231, each limiting side cover 232 abuts against the outside of each insertion end 33, each insertion end 33 abuts against each corresponding limiting part 23, each stopper plate 35 abuts against and locks below the flange 14 along the vertical direction D, and each second fixing structure 34 is locked to each first fixing structure 15. Referring to Figures 10 to 13, when each slide frame 30 slides to the unlocked position, each insertion end 33 disengages from each limiting side cover 232, each stopper plate 35 disengages from each flange 14, and each second fixing structure 34 disengages from each first fixing structure 15. As a result, the top lid 20 and each slide frame 30 can be separated from the box body 10 (i.e., as shown in Figure 13). In this way, by sliding each slide frame 30 between the locked position and the unlocked position, the top lid 20 and each slide frame 30 can be locked or unlocked relative to the box body 10, enabling easy and quick locking and unlocking, and preventing each slide frame 30 from wobbling in the left-right, front-back, and up-down directions relative to the top lid 20 or the box body 10 when locked.
[0025] In this embodiment, when the slide frame 30 is in the release position, each positioning tab 331 is still partially inserted into each slot 231, but is not locked in place. However, the present invention is not limited to this, and when the slide frame 30 is in the release position, each positioning tab 331 may be completely detached from each slot 231, and this does not affect the state in which the top cover 20 and each slide frame 30 are released from the box body 10.
[0026] To further explain, please refer again to Figures 2-4, 9, 10, and 12. In each slide frame 30, the stopper plate 35 extends from the inner wall of the connecting frame 32 and is positioned offset from the flange 14 in the vertical direction D. Specifically, the stopper plate 35 in each slide frame 30 is parallel to the flange 14 and positioned below the flange 14, so when the slide frame 30 is in the locked position, it abuts against the flange 14 below and stops, preventing the top cover 20 and each slide frame 30 from separating from the box body 10 along the vertical direction D. In this embodiment, there are two stopper plates 35 in each slide frame 30, which are provided on the inner wall of the connecting frame 32 at intervals, but the present invention is not limited to this, and there may be one stopper plate 35 in each slide frame 30, or three or more. Any configuration is acceptable as long as it can effectively stop against the flange 14.
[0027] Referring again to Figures 2 and 6, the specific structure and arrangement of each first fixing structure 15 and each second fixing structure 34 will be described below. In this embodiment, there are two second fixing structures 34 in each slide frame 30, each provided on the inner wall of the side frame 31, but the present invention is not limited thereto. Each first fixing structure 15 is a locking rib. Each locking rib has a first engaging bevel 151 facing both ends of each slide frame 30. Each second fixing structure 34 is a wedge-shaped block. Each wedge-shaped block has a second engaging bevel 341 facing one side of the locking rib. As a result, the first engaging bevel 151 and the second engaging bevel 341 face each other and are arranged complementaryly and parallel to each other. When each slide frame 30 is in the locked position, each second engaging bevel 341 engages with the corresponding first engaging bevel 151, thereby locking and fixing each slide frame 30 to the box body 10. On the other hand, when each slide frame 30 is in the release position, each second engaging slope 341 disengages from the corresponding first engaging slope 151, and each slide frame 30 is released from its locking state with respect to the box body 10.
[0028] Further explanation will be given with reference to Figure 6. In this embodiment, since the wedge-shaped blocks of each second fixing structure 34 are located below the locking ribs of the first fixing structure 15, the first engaging slope 151 of the first fixing structure 15 is located below the locking ribs, and the second engaging slope 341 of the second fixing structure 34 is located above the wedge-shaped blocks. As a result, when each slide frame 30 slides toward each limiting portion 23 (i.e., slides from the unlocked position to the locked position), the first engaging slope 151 and the second engaging slope 341 act as guides for each other, allowing the wedge-shaped blocks of the second fixing structure 34 to slide smoothly and be locked and fixed below the locking ribs of the first fixing structure 15.
[0029] Referring again to Figures 2, 3, and 5, each first side frame 21 is provided with a pair of positioning ribs 211, and each side frame 31 is provided with a pair of spaced-apart positioning grooves 311. Specifically, each positioning rib 211 in each first side frame 21 is positioned corresponding to the corresponding limiting portion 23, and each positioning rib 211 and each positioning groove 311 are provided upright relative to each first side frame 21 and each side frame 31. Each positioning rib 211 can selectively engage with any of the positioning grooves 311 of the corresponding side frame 31. Thus, when each slide frame 30 is in the locked position, each positioning rib 211 engages with the positioning groove 311 closer to the insertion end 33. On the other hand, when each slide frame 30 is in the released position, each positioning rib 211 engages with the positioning groove 311 further from the insertion end 33. In this way, each slide frame 30 can perform a positioning function in both the locked and unlocked positions, and when the user slides each slide frame 30, they can recognize that they have reached the locked or unlocked position by the feedback sensation when each positioning rib 211 engages with one of the positioning grooves 311.
[0030] To further explain, refer again to Figures 1, 2, 7, 8, and 11. The top cover 20 has a pair of recesses 24. Each recess 24 is positioned adjacent to the second side frame 22, and each recess 24 has a retaining surface 241 facing one side of the second side frame 22. A locking claw 321 is provided on the upper part of each connecting frame 32. When each slide frame 30 is in the released position, each locking claw 321 engages with the retaining surface 241 of the corresponding recess 24. This restricts each slide frame 30 in the vertical direction and prevents it from falling off the top cover 20.
[0031] Referring again to Figures 2, 3, and 8, the slide frame lock type sealed box of the present invention further comprises a seal ring 40. In this embodiment, the seal ring 40 is a silicone ring or a rubber ring, but the present invention is not limited thereto. The top lid 20 has a generally rectangular groove 25. The seal ring 40 is fitted into the groove 25 and elastically contacts the top lid 20 and the enclosure wall 12, thereby providing a sealing effect between the top lid 20 and the box body 10. In this embodiment, the groove 25 extends upward from the bottom surface of the top lid 20, so that the seal ring 40 elastically contacts the upper end of the enclosure wall 12. However, the present invention is not limited thereto, and for example, the groove 25 may extend from the outside to the inside of the top lid 20, so that the seal ring 40 elastically contacts the inside of the enclosure wall 12, or the groove 25 may extend from the inside to the outside of the top lid 20, so that the seal ring 40 elastically contacts the outside of the enclosure wall 12. Furthermore, when each slide frame 30 is in the locked position, each second engaging slope 341 engages with the corresponding first engaging slope 151, so that the box body 10 is pushed upward in the vertical direction D, and as a result the seal ring 40 is elastically brought into contact with the top lid 20 and the enclosure wall 12, ensuring that a good sealing effect is reliably obtained.
[0032] As described above, the present invention possesses industrial applicability, novelty, and inventive step. However, the present invention is not limited thereto, and various modifications and variations may be made by those skilled in the art, provided they do not deviate from the spirit and substance of the present invention; all such modifications and variations fall within the scope of the utility model registration claims of the present invention.
