Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
The utility model provides a lunch box, this lunch box includes lid part, base part, connecting wire. The structure of the cap portion is the same as the prior art, and can also be represented by fig. 1, as shown in fig. 1, the cap portion includes: a box cover 101, a box cover tongue 104 and a cover main edge 103. Fig. 3 and 4 are block diagrams of two embodiments of the base part, respectively. First, as illustrated in fig. 3, the base portion includes: a base 301, a base tongue 303, a bottom main edge 302.
The box cover 101 and the base 301 are both provided with only one rectangular open groove, and the openings of the two grooves can be correspondingly overlapped, which means that the long edge of the opening of the box cover 101 is equal to the long edge of the opening of the base 301, and the short edges are also equal.
The connecting line 102 is a long side of the opening of the box cover 101, and at the connecting line 102, the opening of the box cover 101 is connected with the opening of the base 301, which means that the connecting line 102 connects the box cover part and the base part into a whole, and thus the connecting line 102 is also a long side of the opening of the base 301.
The long side of the strip-shaped cover main edge 103 is connected to the outer side of the long side of the opening of the box cover 101, which is different from the connecting line 102; the long bottom edge of the trapezoidal box cover tongue 104 is connected to the outer side of the cover main edge 103, and a linear cover edge crack 105 parallel to the connecting line 102 is arranged inside the box cover tongue 104.
The long side of the long strip-shaped bottom main edge 302 is connected to the outer side of the other long side of the opening of the base 301 relative to the connecting line 102; the long bottom edge of the trapezoidal base tongue 303 is connected to the outer side of the bottom main edge 302 and corresponds to the box cover tongue 104; the base tongue 303 has a base slot 306, and the base slot 306 divides the base tongue 303 into a rotating portion 307 and a stationary portion (not numbered in the figures, referring to the portion of the base tongue excluding the rotating portion). Here, the correspondence between the connection position of the long bottom side of the base tongue 303 and the connection position of the box cover tongue 104 means that when the long side of the opening of the box cover 101 different from the connection line 102 is engaged with the long side of the opening of the base 301 different from the connection line 102 by pressing, the box cover tongue 104 can be engaged with the base tongue 303, and the rotating portion 307 can pass through the cover edge slit 105 and be rotated.
Therefore, the utility model discloses in, the base crack divide into fixed part and rotating part with the base tongue, rotating part can pass and rotated from lid reason crack, after splendid attire food and make its uncovered each limit and the corresponding edge laminating of base through pressing down the lid in the base, lid main reason also with the laminating of end main reason, pass and then rotate it in following the lid reason crack with rotating part again, rotating part just intersects and becomes difficult to deviate from with lid reason crack, this fastness of having guaranteed lid part and base part combination, the base tongue can't freely deviate from in the lid reason crack, the loss of food has been prevented and has been spilt.
In order to improve the tightness of the fit between the lid portion and the base portion, the lid portion may further include 2 lid edges (106 and 107, respectively) respectively connected to the outer sides of the 2 short sides of the opening of the lid 101; the base part may correspondingly comprise 2 bottom edges (304 and 305, respectively) attached to the outside of the open 2 short sides of the base 301. Thus, when the lid 101 is pressed to engage the open edges of the base 301, the lid edges 106 and 107 engage the bottom edges 304 and 305, respectively, thereby increasing the tightness of engagement of the lid portion with the base portion and further preventing food from being spilled.
In the embodiment of FIG. 3, the base slot 306 is linear and begins at a waist of the base tongue 303 and ends within the base tongue 303. The structure is simple and easy to realize and operate.
In the embodiment of fig. 4, the base is designated 401, the bottom main edge is designated 402, the base tongue is designated 403, the bottom edges corresponding to the cover edges 106 and 107 of fig. 1 are designated 404 and 405, respectively, the base slit is designated 406, the rotating portion is designated 407, and the portion of the base tongue 403 excluding the rotating portion 407 is a fixed portion (not designated). In fig. 4, the base slot 406 is U-shaped and is located inside the base tongue 403, and the opening of the U-shape is facing the short bottom side of the base tongue 403, so that the rotating portion 407 can be rotated around a straight line 408 formed by two ends of the opening of the U-shape, and thus the straight line 408 is the rotating axis of the rotating portion 407. The U-shaped base slit is also simple and has better binding firmness with the lid edge slit after rotation.
Fig. 3 and 4 show only two embodiments of the base slit, but in fact the base slit may also have other forms, such as changing a straight form in fig. 3 to a curved form, changing a U form in fig. 4 to a V form, etc. In fact, the form in base crack is various and can't be exhaustively, as long as can divide into the base tongue fixed part and these two parts of rotating part to rotating part can pass and then rotated from lid edge crack, all is in the utility model discloses a within the scope of protection.
Preferably, the long bottom edge of the box cover tongue and the long bottom edge of the base tongue are respectively positioned on the outer side of the middle part of the cover main edge and the outer side of the middle part of the base main edge, so that the balance of connection of the box cover part and the base part is facilitated.
Therefore, the utility model has the advantages of it is following:
(1) the utility model discloses in, the base crack divide into fixed part and rotating part with the base tongue, rotating part can pass and rotated from lid reason crack, when splendid attire food in the base and make its uncovered each limit and the corresponding marginal laminating of base through pressing down the lid after, lid main reason also with the laminating of end main reason, pass and then rotate it in the lid reason crack with rotating part again, rotating part just intersects and becomes difficult to deviate from with the lid reason crack, this fastness of having guaranteed lid part and base part combination, the base tongue can't freely deviate from in the lid reason crack, the loss of food has been prevented and has been spilt.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
