Detailed Description
Example 1: as best seen in fig. 1 and 2, the box cover with an outer convex edge box opening suitable for a box body with a square structure comprises: a cover body 1 made of plastic material.
The novel box cover is characterized in that a circle of stepped groove 5 formed by a deep groove 3 and a shallow groove 4 and used for guiding a box opening of the box body into is arranged on the periphery of the cover body 1, the deep groove 3 is an embedded groove used for being embedded into the box opening of the box body in a matched mode, a circle of boss 6 capable of being clamped into the lower edge of an outer convex edge of the box opening of the box body is arranged on the side wall of the deep groove 3 of a notch of the stepped groove 5, a circle of elastic arc-shaped sheet 7 used for preventing the box cover from being separated from the box opening is arranged on the side wall of the shallow groove 4 of the notch of the stepped.
When the box cover is pressed downwards, the elastic arc-shaped sheet 7 at the side wall of the shallow groove 4 of the stepped groove 5 is pressed and deformed to increase the notch, the box opening of the box body can be embedded into the deep groove 3 of the stepped groove 5, and when the box cover is pressed in place, the boss 6 arranged at the side wall of the deep groove 3 at the notch of the stepped groove 5 can be clamped into the lower edge of the outer convex edge of the box opening of the box body. At this time, the box cover can be tightly covered on the box body by means of the clamping fit of the notch boss 6 of the stepped groove 5 and the lower edge of the outer convex edge of the box opening and the elastic fit of the elastic arc-shaped piece 7 and the inner wall of the box opening. When the box cover needs to be opened, one angle of the box cover is pulled upwards by using the pull lugs 8 arranged on the periphery of the cover body 1, so that the box cover tightly covered on the box body can be easily opened from the box opening.
Example 2: as can be clearly seen from fig. 3 and 4, this is a box cover with an outer convex edge box opening suitable for a round structure box body, and the basic structure is the same as the embodiment, except that: the cover body 1 is composed of a cover frame 11 made of plastic materials and a flexible elastic cover surface 12 made of silica gel materials;
the cover frame 11 is a cover frame with a cross section of F, the cover frame 11 forms an upper frame opening 13 and a lower frame opening 14 by the F-shaped cross section, the upper frame opening 13 is provided with a frame binding surface 15 which is bonded with the flexible elastic cover surface, and the lower frame opening 14 forms a boss 6 which can be clamped into the lower edge of the outer convex edge of the box opening of the box body;
the flexible elastic cover surface 12 is composed of a disk-shaped surface 16 and a circle of arc-shaped sheets 17 arranged on the back surface of the disk-shaped surface and used for preventing the box cover from being separated from the box opening and turning outwards, and a cover attaching surface 19 adhered with the upper frame opening 13 of the cover frame 11 is arranged around the disk edge 18 of the disk-shaped surface 16.
The plate edge 18 of the plate surface 16 of the flexible elastic cover surface 12 is embedded in the upper frame opening 13 of the cover frame 11, and the cover binding surface 19 of the flexible elastic cover surface 12 is connected with the frame binding surface 15 of the upper frame opening of the cover frame 11 into a whole through viscose glue.
The cover frame 11 and the flexible elastic cover surface 12 are connected into a whole to form a box cover with the same structure as that of the embodiment 1. Namely: a circle of stepped grooves 5 which are formed by deep grooves 3 and shallow grooves 4 and are used for guiding the box opening of the box body are formed on the periphery of the cover body 1, the deep grooves 3 of the stepped grooves 5 are embedded grooves for the box opening of the box body to be matched, a circle of side walls of the deep grooves of the notch of the stepped grooves 5 is formed by a lower frame opening 14 of a cover frame 11 and can be clamped into a boss 6 at the lower edge of an outer convex edge of the box opening of the box body, and a circle of arc-shaped sheets 17 which are outwards rolled from the back of a flexible elastic cover surface 12 and are arranged on the side walls of the shallow grooves 4 of the notch of the stepped grooves 5 form elastic arc-shaped sheets 7 which have the same functions.
The flexible elastic cover surface 12 is formed integrally with the cover frame 11 in a thermoplastic manner to form the cover body 1.
The method of using the cap 1 having the flexible and elastic cap surface 12 is the same as that of example 1, except that:
the back of the disc-shaped surface 16 based on the flexible elastic cover surface 12 is in flexible contact with the box opening after the box cover and the box body are covered, so that the sealing performance is better after the box cover and the box body are covered;
the disk-shaped surface 16 based on the flexible elastic cover surface 12 has good elasticity, so that when food in the box body is less, one side of the cover body 1 can be pulled upwards by utilizing the pull lugs 8, redundant air in the box body is discharged from a pulled gap by pressing the disk-shaped surface 16 of the flexible elastic cover surface 12, then the cover body 1 is pressed in the box body, at the moment, the air in the box body is reduced, and the oxidation of the food in the box body can be slowed down. When the food in the box body is higher than the box opening of the box body, the food which is higher than the box opening can jack up the disc surface 16 of the cover body 1 to deform by utilizing the elasticity of the flexible elastic cover surface 12, so that more storage space can be obtained for the food, the volume capacity is increased, and the box cover can still be buckled on the box body.
The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of the ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, its framework form can be nimble changeable, can derive series of products. But merely as a matter of simple deductions or substitutions, should be considered as belonging to the scope of patent protection of the present invention as determined by the claims submitted.
