[0005] ,

[0001] The present invention relates to a freshness-keeping container, and particularly to a pressing and locking structure in the freshness-keeping container.

Background Art

[0002] Freshness-keeping containers used in daily life are very convenient. By storing items such as leafy vegetables, fruits, and dried fruits, the items in the container can be isolated from the external environment and the storage period can be extended. Also, it is easy to stack and store or keep the containers.

[0003] In addition, a general freshness-keeping container is composed of a container body and a lid that can be engaged with the container body. Further, as an engagement method between the container body and the lid, a structure is adopted in which wing-piece locking edges are provided on both sides of the lid, and an outer folding edge is provided on the upper edge of the container body. Thus, by engaging the wing-piece locking edges of the lid with the outer folding edge of the container body, a locked state can be obtained. However, while the above-described locking method can bring a close engagement state between the container body and the lid, after unlocking the engagement between the container body and the lid, since the user needs to lift the wing-piece locking edges with both hands to disengage the engagement and remove the lid from the container body, it lacks convenience in use.

The above lid body 20 includes a lid plate 21 and at least a pair of engaging grooves 22 provided on the opposite side of this lid plate 21, and the number of these engaging grooves 22 corresponds to the number of the above elastic locking pieces 12. By inserting the engaging claw 122 of each of the above elastic locking pieces 12 into each engaging groove 22, the above lid body 20 is positioned on the above main body portion 11.

[0021] Preferably, in this embodiment, two of the above elastic locking pieces 12 can be provided on the opposite side of the above storage space 110 respectively. Further, the above lid body 20 is provided with two engaging grooves 22 respectively corresponding to the opposite side of the above lid plate 21.

[0022] In addition, in order to give good structural strength to each of the above elastic locking pieces 12 arranged on one side surface, the above container body 10 further includes an extension piece 13. This extension piece 13 is connected to each of the above elastic locking pieces 12 provided on one side surface of the above main body portion 11.

[0023] Furthermore, the above pair of wing pieces 30 are rotatably coupled to the opposite side of the above lid plate 21. Each wing piece 30 is provided corresponding to the position of each of the above elastic locking pieces 12, and on the side surface facing the above lid body 20, at least one protrusion 31 and a locking claw 32 are provided corresponding to the number and position of the above engaging grooves 22. In this embodiment, this protrusion 31 and this locking claw 32 are integrally formed on each wing piece 30.

[0024] The cover plate 21 is equipped with a pair of flanges 23. Each flange 23 is provided projecting outward from one side of each engagement groove 22 and covers the side surface of each wing piece 30. Each flange 23 is formed in a U shape and includes two side walls 231 and a top wall 232 connecting these two side walls 231. Each side wall 231 has a pivot hole 230 formed therein. On the other hand, each wing piece 30 is provided with a pivot 33 at both ends. Thus, each wing piece 30 is connected to the cover plate 21 by inserting the pivot 33 into each pivot hole 230.

[0025] Referring to Figures 3 to 5, a schematic perspective view of the freshness preservation container structure according to the present invention, a cross-sectional view showing the connection state at the locking claw position of the wing piece of the freshness preservation container structure, and a cross-sectional view showing the connection state at the projection position of the wing piece of the freshness preservation container structure are shown, respectively. As shown in Figure 4, in this embodiment, the container body 10 further comprises a folded piece 14. This folded piece 14 is bent and extended from the upper edge of the main body portion 11, forming a buffer space 140 between it and the outer surface of the main body portion 11. Furthermore, the folded piece 14 is connected to the pair of elastic locking pieces 12 and integrally molded.

[0026] Referring again to Figures 1 and 2, when the container body 10 and the lid 20 are joined, the projections 32 of each wing piece 30 protrude from the side of the elastic arm 121 of each elastic locking piece 12, and the locking claws 32 of each wing piece 30 are locked to the lower side of each engagement groove 22 (see Figure 4). In this embodiment, the projections 32 penetrate into the engagement groove 22 and are located above the engagement claws 122 of the elastic locking piece 12.

[0027] Furthermore, the freshness-preserving container structure 1 further includes a sealing member 40 sandwiched between the main body 11 and the lid plate 21. Specifically, an annular groove 210 is provided on the inner wall surface of the lid plate 21, and the sealing member 40 is positioned within the annular groove 210. As shown in Figure 5, when the lid 20 covers the main body 11, the engaging claws 122 of each elastic locking piece 12 engage with each engaging groove 22 and are pressed against the edges of the engaging grooves 22. As a result, the lid 20 is positioned on the container body 10, and the sealing member 40 maintains an airtight seal between the two.

[0028] Referring to Figures 6 to 9, schematic diagrams illustrating the operation of the freshness preservation container structure according to the present invention are shown. When opening the freshness preservation container structure 1, force is applied to the lower edges of the pair of wing pieces 30 to push them, causing the upper edges of the pair of wing pieces 30 to rotate toward the main body 11. At this time, the locking claws 32 of each wing piece 30 disengage from the lower side of the engagement groove 22 (see Figures 6 and 8), and the projections 31 of each wing piece 30 press against the elastic arms 121 of each elastic locking piece 12 (see Figure 7). As a result, the elastic arms 121 move the engagement claws 122 and disengage them from the engagement groove 22 (see Figure 9).

[0029] Furthermore, referring to Figure 10, a schematic diagram is shown illustrating the separated state of the container body and lid of the freshness preservation container structure according to the present invention. As described above, the elastic arm 121 moves the engaging claw 122 and disengages it from the engaging groove 22, thereby separating the lid 20 from the container body 10. If the container body 10 is suspended in mid-air, the above operation will cause the container body 10 to fall naturally due to its own weight, and it will be possible to separate it from the lid 20.
