The first figure shows a perspective view of the storage case 1 of the present invention.

The second and third figures show the state when the storage box 1 is opened. The fourth figure shows the state when the storage box 1 is closed. Referring to the second and third figures, the storage box of the present invention comprises a box body 2 and a cover body 3. The box body 2 is made of a plastic material, and the box body 2 can be slightly stretch-resistant after being molded. Preferably, a plastic material such as polyethylene or polypropylene is used, and in the embodiment, it is made of polypropylene. The cover body 3 can be made of other rigid materials, and the same plastic material as the case body 2 can also be used. In the embodiment, the cover body 3 is also made of polypropylene. The casing 2 has opposite side walls 21, 27. The side wall 21 defines an inner wall surface 22 and an outer wall surface 23. The outer wall surface 23 is formed with a protruding engaging block 24.

The cover body 3 includes a top plate 31, a clamping piece 4, an engaging groove 45 and two convex ribs 5. The top plate 31 of the cover 3 has opposite side edges 311, 312, and the side edges 312 of the top plate 31 are connected to the side walls 27 of the casing.

Referring to the third and fourth figures, the casing 2 is formed with a joint portion 25 on the side wall 27 thereof. The cover body 3 is formed with a joint portion 33 on the side edge 312 thereof, and the casing 2 and the cover body 3 are transmitted through the joint portion. 25 and the joint of the joint portion 33 are not detachably coupled together, and the joint portion 25 and the joint portion 33 can be bent relative to each other. Therefore, the opening of the storage case 1 is achieved by swinging the lid body 3 relative to the casing 2 with the joint portion 25 and the joint portion 33 as an axis, and the connection between the box body 2 and the lid body 3 can be replaced with other pivot joint members. In order to achieve a similar action, and a detachable or non-removable member can be selected for engagement, and is not limited to the setting of the embodiment.

Referring to the second and third figures, the engaging piece 4 is formed downwardly and outwardly from the side edge 311 of the top plate 31. The engaging piece 4 defines an adjacent section 41 adjacent to the top plate 31 and away from the top plate 31. A free section 42, the engaging piece 4 has an inner surface 43 facing the casing 2, and the inner surface 43 defines a guiding surface 44 corresponding to the free section 42. In the embodiment, the guiding surface 44 has a circular arc surface. The surface 43 is recessed inwardly corresponding to the adjacent segment 41 to form an engaging groove 45. Since the engaging piece 4 is extended downward and outward, the guide surface 44 also correspondingly forms an outwardly curved arc surface.

The two convex ribs 5 are formed by an inner surface 32 of the top plate 31 protruding downward, and the number and arrangement of the convex ribs 5 can be determined as needed, and are not limited to the number of the embodiments.

The fifth and sixth figures show the process in which the lid body 3 of the storage box is closed with the casing 2. Referring to the stage A of the fifth and sixth figures, when a user presses the cover 3 to cover the case 2, the guide surface 44 of the engaging piece 4 first abuts against the engaging block 24, and is engaged. The guide surface 44 of the sheet 4 moves downwards as the lid body 3 is pressed down. Since the guide surface 44 has a circular arc surface, it can slide downward relative to the engaging block 24 while abutting against the engaging block 24. The side wall 21 of the casing 2 is still not deformed at this time. In addition, the shape of the guide surface 44 can also be selectively designed to allow the guide surface 44 to slide downward relative to the engaging block 24 while abutting the engaging block 24, such as a bevel or the like.

Referring again to the phase B of the fifth and sixth diagrams, during this process, the portion of the guide surface 44 close to the adjacent segment 41 will slide downward with the guide surface 44, and the home body will also press the clamping block 24, and the box will be pressed. The side wall 21 of the body 2 is subjected to the pressure transmitted from the guide surface 44 through the engaging block 24, and thus is slightly recessed and contracted toward the space of the casing 2.

Continuing with reference to stage C of the fifth and sixth figures, when the snap block 24 has been raised to the portion of the guide surface 44 that is adjacent to the adjacent segment 41 and is about to enter the engagement slot 45. The two convex ribs 5 can simultaneously abut against the inner wall surface 22 of the side wall 21, and correspondingly generate a force for pushing the side wall 21 in accordance with the depression of the cover 3. Thereby, the two convex ribs 5 offset the engaging piece 4 to the side wall 21 The pressure prevents the side wall 21 from being further recessed, thereby reducing the concave shape variable generated by the pressing of the side wall 21 by the engaging piece 4.

Finally, referring to the stage D of the fifth and sixth figures, the depressed pressing piece 4 is guided by the guiding surface 44 to cause the engaging block 24 to slide along the guiding surface 44 and relative to the guiding surface 44 to embed the card. In the slot 45. At this time, the side wall 21 which is slightly recessed and contracted is no longer pressed by the guide surface 44 of the engaging piece 4, and is resisted by the tensile elasticity of the polypropylene material itself, and is penetrated by the two convex ribs 5 The inner wall surface 22 of the side wall 21 is housed, and thus rebounds outward, returning from the deformation of the slightly concave shape. In other words, by the support of the two convex ribs 5, the side wall 21 of the casing 2 does not need to rely on its own tensile elasticity to recover the deformation, thereby avoiding the problem that the tensile strength of the side wall 21 is fatigued.

Through the above arrangement, the storage box 1 of the present invention can solve the problem that the side wall of the conventional storage box is reversely switched, and the side wall is deformed by the reverse depression, and the side wall is elastically fatigued to cause a permanent concave deformation, and the storage box is made. The problem that the box and the cover cannot be fastened.

Preferably, referring to the second and fourth figures, the two convex ribs 5 each have a support surface 51 facing the engaging piece 4. Referring again to the stage D of the fifth and sixth figures, when the engaging block 24 slides along the guiding surface 44 into the engaging groove 45, the supporting surface 51 of the two convex ribs 5 will still abut against the inner wall surface of the side wall 21. twenty two. After the engaging block 24 is inserted into the engaging groove 45, although the side wall 21 is no longer pressed by the engaging piece 4 to form a recess, the user may directly press the side wall 21 during the long-term use of the storage case 1. The inward depression of the side wall 21 also causes a permanent depression deformation of the side wall 21 due to the elastic fatigue. By the provision of the support surface 51 of the two convex abutment ribs 5, the cover body 3 and the casing 2 can be prevented from being closed. The side wall 21 is still likely to be deformed inwardly.

Referring again to the second, third and fifth stages, the two convex ribs 5 each have a guide surface 52. In the present embodiment, the guide surface 52 is a sloped surface and faces the engaging piece 4. . Through the arrangement of the guiding surfaces 52 of the two convex ribs 5, when the user presses the engaging piece 4, the two convex ribs 5 can avoid a top edge 211 of the side wall 21 without being stuck on the side wall 21. The two convex ribs 5 can continue to slide downward while abutting against the inner wall surface 22 of the side wall 21 by the two guiding surfaces 52. In addition, the shape design of the two guiding surfaces 52 can also be selectively designed into other shapes that can achieve this effect, such as designing a circular arc surface and the like.

Preferably, referring to the second figure, the two convex ribs 5 are respectively opposite to the sides of the inner surface 43 of the engaging piece 4 on the side of the engaging groove 45. Through the positional arrangement of the two convex ribs 5 described above, During the process of covering the cover body 3 with the casing 2, the two convex ribs 5 will abut against the side wall 21, and just be located on both sides of the point of application of the pressing piece 4 against the side wall 21, as shown in FIG. As shown in the stage D, the pressure applied by the engaging piece 4 is more effectively offset, and the concave shape variable of the side wall 21 is effectively reduced.

In addition, referring to the first and fourth figures, the engaging piece 4 is formed with a protruding block 47 on the outer surface 46 thereof. The protruding block 47 is corresponding to the engaging groove 45, and the engaging piece 4 is disposed through the protruding block 47. The inner surface 43 can be recessed inwardly to form a space sufficient for the engaging groove 45 to engage with the engaging block 24, so that the engaging groove 45 can be used as the groove bottom of the protruding block 47, and it is not necessary to form a sufficient fit. The block 24 mates with the engagement groove 45 to deliberately increase the thickness of the engaging piece 4.

Preferably, referring to the first and second figures, a flange 26 surrounding the entire casing 2 is formed on the outer surface of the casing 2. The cover body 3 further has a cover edge 34. The cover edge 34 extends downward from the edge of the top plate 31 to form and surround the entire top plate 31. When the case 2 is covered with the cover 3, the cover edge 34 of the cover 3 is just The edge of the side wall of the entire casing 2 can be covered, and the cover edge 34 of the cover 3 can abut against the flange 26 of the casing 2, whereby the storage box can better protect the components housed in the casing from falling out.

Through the above arrangement, the storage case of the present invention solves the problem that the side wall 21 may be deformed inwardly due to the use of the user when the cover body 3 and the case 2 are closed by the use of the convex rib. Further, the storage case of the present invention can solve the problem that the side wall of the casing of the conventional storage case is permanently deformed after being used for a long period of time, and the casing of the storage case and the cover cannot be fastened.

In any event, anyone can obtain sufficient teaching from the description of the above examples, and it is understood that the present invention is indeed different from the prior art, and is industrially usable and progressive. It is the invention that has indeed met the patent requirements and has filed an application in accordance with the law.
