Description

Technical Field

[0001] This utility model relates to the field of bento boxes, and more particularly to a three-compartment bento box. Background Technology

[0002] A bento box is a container specifically designed to hold food such as meals and fruits. When going out, people often put food in a bento box, and when it's time to eat, they can simply open the bento box to eat. In modern life, bento boxes have become an essential household item.

[0003] Existing bento boxes are designed with multiple compartments for storing different foods. A sealing ring is installed between the lid and the box body to prevent food from spilling out of the bento box through gaps. However, existing sealing rings cannot seal every compartment, leading to cross-contamination of flavors between foods in adjacent compartments during use.

[0004] For example, Chinese patent CN217261856U discloses a novel bento box, including a box body, a lid, a sealing ring, and a pressure cap. The box body has a cavity, and a first flange is provided on the outer edge of the cavity opening. The lid fits into the opening of the cavity, and the sealing ring seals the junction between the box body and the lid. The pressure cap is attached to the upper surface of the lid, and deformable spring arms are provided on both sides. The inner side of each spring arm has at least one snap point that engages with the first flange. This invention uses a pressure cap to press the lid tightly onto the box body. The pressure cap only requires two snaps consisting of spring arms and snap points to achieve a detachable connection with the box body, and the deformation caused by the double snaps does not affect the sealing performance of the lid, thereby improving the sealing performance of the double-snap bento box.

[0005] In the aforementioned patent, a sealing ring is used to seal the junction between the box body and the cover. This presents the aforementioned problem. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figure 1-4 As shown, the three-compartment bento box of this utility model includes a box body 01 and a lid 02 rotatably mounted on the box body 01. The box body 01 has an upward-opening receiving space. A T-shaped partition 03 is provided within the receiving space. The top of the partition 03 is flush with the top of the box body 01, and the partition 03 divides the receiving space into three receiving compartments 04 of different volumes. This facilitates the placement of categorized food into different receiving compartments 04.

[0026] A sealing element 05 is provided inside the lid 02. When the lid 02 and the box 01 are in the closed state, the sealing element 05 covers the partition 03 and the top of the lid 02, sealing each compartment 04 individually. When food or liquid food with different odors is placed in two adjacent compartments 04, it can effectively prevent cross-contamination of odors and prevent liquid food from overflowing into adjacent compartments 04.

[0027] The sealing element 05 includes a sealing outer ring 06 and a support strip 07 located inside the sealing outer ring 06 corresponding to the partition 03. The support strip 07 divides the sealing outer ring 06 into the same number of square through holes 08 as the receiving chambers 04. Each through hole 08 has an axially extending lower sealing ring 09 on one side, which is adapted to the receiving chamber 04. When the cover 02 and the box 01 are closed, the lower sealing ring 09 is inserted into the receiving chamber 04. An upper step 10 is provided between the lower sealing ring 09 and the sealing outer ring 06. When the support strip 07 covers the box 01, the lower sealing ring 09 is inserted into the corresponding receiving chamber 04, and the outer wall of the lower sealing ring 09 abuts against the side wall of the receiving chamber 04. This achieves individual sealing of each receiving chamber 04.

[0028] The top of the box 01 is integrally molded with an outer ring 12, the inner side of which is flush with the side wall of the accommodating space. The top of the outer ring 12 is flush with the top of the partition 03. When the cover 02 and the box 01 are closed, the top of the outer ring 12 abuts against the upper step 10. This provides support for the seal 05 and also restricts further movement of the seal 05.

[0029] On the other side of each through hole 08, an upper sealing ring 13 extending axially is provided, with the inner wall of the upper sealing ring 13 flush with the side wall of the through hole 08. An inner connecting strip 14 of the same width as the support strip 07 is provided between two adjacent upper sealing rings 13, and an outer connecting ring 15 is provided between the upper sealing ring 13 and the sealing outer ring 06 with an arc transition.

[0030] The cover 02 is integrally formed and fixedly connected with the same number of matching retaining rings 16 as the receiving chamber 04. An inner snap-fit ​​groove 17, adapted to the inner connecting strip 14, is provided between adjacent retaining rings 16. An outer snap-fit ​​groove 18, adapted to the outer connecting ring 15, is provided between the retaining ring 16 and the edge of the cover 02. During use, the expansion groove 16 can be filled with a dispersing agent or left empty. The inner connecting strip 14 is snapped into the inner snap-fit ​​groove 17, and the outer connecting ring 15 is snapped into the outer snap-fit ​​groove 18. The sealing element 05 is then fixed to the cover 02.

[0031] A trapezoidal fixing platform 21 is provided on the side wall of each through hole 08. The area of ​​the fixing platform 21 at one end of the through hole 08 is larger than the area where the fixing platform 21 connects to the side wall. The fixing ring 16 is provided with a fixing groove 20 that matches the fixing platform 21. The cooperation between the fixing groove 20 and the fixing platform 21 prevents the seal 05 from shaking during use.

[0032] One of the mounting platforms 21 adjacent to the partition 03 is provided with an extension 11 extending towards the center of the through hole. After the seal 05 is installed on the cover 02, when cleaning is required, the user grips the extension 11 for anti-slip purposes. The tableware is also placed on the extension to prevent it from falling into the receiving chamber. When placing the tableware, one end of the tableware is placed against the opposite side of the extension, and the other end is secured in the gap between the extension and the cover to prevent it from falling.

[0033] A hinge seat 21 is integrally formed and fixedly connected to one side of the top of the box body 01. A hinge hole is provided through the hinge seat 21. A connecting seat 22 corresponding to the hinge seat 21 is provided on the cover body 02. A hinge shaft adapted to the hinge hole is provided on the connecting seat 22. The rotational connection between the box body 01 and the cover body 02 is achieved through the cooperation of the hinge hole and the hinge shaft. When the cover body 02 is opened and closed, it rotates around the hinge hole on the hinge seat 21.

[0034] One side of the hinge base 21 has a notch 23 that communicates with the hinge hole. The width of the notch 23 is smaller than the diameter of the hinge hole. During assembly, the hinge shaft enters the hinge hole through the notch 23. At the same time, the hinge shaft can also be removed from the notch 23, allowing the cover 02 and the box 01 to be separated for easy cleaning of the dead corners of the cover 02 and the box 01.

[0035] A cover plate 24 is provided on the other side of the box body 01. Rotating shafts are provided on both sides of the cover plate 24. Rotating holes adapted to the rotating shafts are provided on the box body 01. The cover plate 24 is rotatably connected to the box body 01 through the cooperation of the rotating shafts and rotating holes, and is positioned opposite the hinge seat 21 on both sides of the box body 01. Two locking holes 25 are provided on the top of the cover plate 24, and locking platforms 26 adapted to the locking holes 25 are provided on the cover body 02. When the cover body 02 is closed on the box body 01, the locking platforms 26 engage in the locking holes 25, preventing the cover body 02 from separating from the box body 01. To open the cover body 02, the operator rotates the cover plate 24, separating the locking holes 25 and locking platforms 26, and then rotates the cover body 02, causing it to rotate around the hinge seat 21, thus opening the cover body 02 and the box body 01.

[0036] In use, different foods are placed in different compartments 04. The lid 02 is rotated to close the lid and the box 01. When the lid and box 01 are closed, the sealing element 05 on the lid 02 seals the partition 03 inside the box 01 and the box 01 itself, effectively sealing each compartment 04 individually. This prevents cross-contamination of flavors between foods in adjacent compartments 04.

[0037] If the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0038] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
