DETAILED DESCRIPTION

[0031] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0032] like Figure 1-11As shown, a can cover for reducing the accumulation of foreign matter comprises a fixing ring 80, a top cover 10 and a connecting leaf 90; the top cover 10 is connected to the fixing ring 80 in a flippable manner and is used to cover the fixing ring 80; the connecting leaf 90 is connected to the fixing ring 80 in a flippable manner; the top cover 10 is formed with a concave groove 105 and an opening operation concave position 106, the opening operation concave position 106 is communicated with the concave groove 105, and a protruding seat 17 is arranged in the concave groove 105; The width of the raised seat 17 gradually increases from the side of the raised seat 17 away from the opening operation recess 106 to the side of the raised seat 17 close to the opening operation recess 106; a buckling wall 18 is provided on the side of the raised seat 17 close to the opening operation recess 106, and the connecting page 90 includes a covering portion 97, which is used to cover the recessed groove 105 and the raised seat 17, and a hook 91 for buckling on the buckling wall 18 is provided on the covering portion 97.

[0033] When closing the can lid, the top cover 10 can be turned over in the direction of the fixing ring 80 and covered on the fixing ring 80, and then the connecting page 90 can be turned over, and the hook 91 of the covering part 97 can be used to buckle on the buckling wall 18. At this time, the covering part 97 covers the concave groove 105 and the protruding seat 17 to reduce the exposed area of ​​the concave groove 105, thereby reducing the accumulation of foreign matter in the concave groove 105 and the protruding seat 17. When opening the can lid, a finger can be placed on the opening operation recess 106 and the covering part 97 can be pushed upward, so that the hook 91 is separated from the buckling wall 18 under the action of the pushing force, and then the connecting page 90 can be turned over in the direction away from the top cover 10, and the top cover 10 can be turned outward to open the can lid. Therefore, the utility model provides a can lid with reduced accumulation of foreign matter, which can be covered by the covering part 97 by adopting the covering part 97 on the connecting page 90. The recessed groove 105 and the raised seat 17 are covered to reduce the accumulation of foreign matter in the recessed groove 105 and the raised seat 17. On the basis of using the covering part 97 for the connecting page 90, the recessed groove 105 and the opening operation groove are formed on the top cover 10, and the raised seat 17 is arranged in the recessed groove 105. At the same time, a buckling wall 18 is arranged on the side of the raised seat 17 close to the opening operation groove, and a hook 91 is arranged on the covering part 97, which can facilitate the buckling and separation of the hook 91 and the buckling wall 18. Since the buckling and separation between the connecting page 90 and the top cover 10 can be realized by the buckling and separation of the hook 91 and the buckling wall 18, the buckling and separation between the connecting page 90 and the top cover 10 can be facilitated. In addition, by reasonably setting the width of the raised seat 17, the contact area between the covering part 97 and the raised seat 17 can be increased, thereby achieving a more stable fit.

[0034] Specifically, the cover portion 97 is also used to abut against the raised seat 17. Preferably, the shape of the cover portion 97 matches the shape of the recessed groove 105, and by using the above configuration of the cover portion 97, the recessed groove 105 can be completely covered to further reduce the accumulation of foreign matter in the recessed groove 105.

[0035] The connecting page 90 further includes a connecting neck 96; one end of the connecting neck 96 is reversibly connected to the fixing ring 80, and the covering portion 97 is disposed on the other end of the connecting neck 96. By adopting the above arrangement of the connecting page 90, it is convenient to manufacture.

[0036] The hook 91 includes a main body 93, a first convex clamping portion 94 and a second convex clamping portion 95; the first convex clamping portion 94 and the second convex clamping portion 95 are respectively arranged on the main body 93, and an elastic embedding groove for the buckle wall 18 to be inserted is formed between the first convex clamping portion 94 and the second convex clamping portion 95, and the first convex clamping portion 94 and the second convex clamping portion 95 are respectively used to limit the buckle wall 18. During the buckle connection between the hook 91 and the buckle wall 18, the buckle wall 18 is inserted into the elastic embedding groove. At this time, the first convex clamping portion 94 and the second convex clamping portion 95 limit the buckle wall 18, so that the buckle connection and separation between the hook 91 and the buckle wall 18 are more convenient, and the buckle connection stability is ensured, which is convenient for processing.

[0037] The top cover 10 is provided with an outer convex wing 19, and the connecting leaf 90 is provided with a reinforcing rib 92 for abutting against the outer convex wing 19 when the top cover 10 is covered on the fixing ring 80 to press the top cover 10 against the fixing ring 80. When in use, when the top cover 10 is covered on the fixing ring 80, the hook 91 of the connecting leaf 90 can be buckled on the buckling wall 18 to lock the top cover 10 on the fixing ring 80. At this time, the reinforcing rib 92 of the connecting leaf 90 abuts against the outer convex wing 19 (such as Figure 3 As shown), during transportation, the fixing ring 80 and the top cover 10 can be prevented from being relatively displaced due to vibration, thereby preventing a large gap from appearing between the fixing ring 80 and the top cover 10, thereby reducing the probability of foreign objects such as small insects or dust entering the can cover.

[0038] A plurality of reinforcing ribs 92 are arranged at intervals on the connecting page 90.

By adopting the above-mentioned arrangement, the structural strength of the fixing ring 80 can be ensured, and it is convenient to satisfy the supporting function of the top inner ring wall and the top outer wall 15.

[0044] As a further preferred embodiment of the utility model, the cavity formed in the fixing ring 80 is suitable for the top of the top cover 10 to extend into. During transportation or storage, multiple can lids can be stacked in sequence, and the top of the top cover 10 of the lower can lid can extend into the cavity of the fixing ring 80 of the adjacent upper can body, so as to save storage space. One end of the top cover 11 forms a mounting end 102, and the other end forms a flat end 103. The mounting end 102 of the top cover 11 is provided with an arc surface formed by rounding. Along the direction away from the flat end 103, the arc surface gradually tilts downward, and the raised seat 17 is formed on the mounting end 102. After the can lid is manufactured, it is necessary to stack the can lids layer by layer and transport them to the place of use. The flat end 103 serves as a support end and is provided with a support plane, which can facilitate the top cover 10 of the can lid to be embedded in the cavity of the fixing ring 80 of the adjacent can body, so as to facilitate the stacking between the can lids. Moreover, for further optimization, in the design, the appropriate plane arc length of the flat end 103 can be determined through multiple experiments, and the area surrounded by the flat end 103 can be expanded to increase the stacking plane area, thereby increasing the stability of the stacking.

[0045] As a further preferred embodiment of the present invention, a fixing structure for fixing the spoon body 20 is provided on the top cover 10, so that the spoon body 20 can be conveniently fixed by the fixing structure.
