Detailed Description
The invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic drawings and illustrate, by way of illustration only, the basic structure of the invention, and which therefore show only the constituents relevant to the invention.
The sealing film in the attached figures has been omitted to avoid any visual effect.
As shown in fig. 1-4, a sealing cap for seed germination experiment comprises: the cover comprises a cover 1 body, wherein a counterweight bin 2 is arranged at the top of the cover 1, the diameter of the cross section of the bottom of the cover 1 is smaller than that of the cross section of the rest positions of the cover 1, a lantern ring 3 is embedded in the outer side of the bottom of the cover 1 in an interference manner, an outward convex cambered surface 4 is arranged at the bottom end of the cover 1, a plurality of through holes 5 are formed in the cambered surface 4, and the through holes 5 are led to the middle of the cover 1 through the inside of the cover 1 and penetrate through the side wall; firstly, a sealing film is attached to the cambered surface 4, and then the circumferential edge of the sealing film is fixed on the cover 1 through the lantern ring 3.
The top of the cover 1 is provided with a counterweight cabin 2, the counterweight cabin 2 is composed of a cavity area horizontally penetrating through the top of the cover 1, and the counterweight cabin 2 is used for storing counterweight gaskets. Two opposite sides of the counterweight chamber 2 are respectively provided with a supporting wall 9, and the gasket is clamped in the two supporting walls 9 in an interference manner, namely, the counterweight part of the cover 1 is not easy to loose and completes the pressing and holding adjustment.
The cross-sectional diameter of the bottom of the lid 1 is smaller than the cross-sectional diameter of the rest of the lid 1, where it is preferred to provide the outside side wall of the bottom of the lid 1 as a ramp 6, i.e. the cross-sectional diameter of the cap 1 at the remaining positions is gradually reduced (forming the slope 6), until the angle between the edge curve 4 connected to the curve 4 and the slope 6 is smaller, the whole body can form a shape which is approximately convex outwards, the sealing film is tightened and the contact surface is larger, the sealing film is less destructive, which is beneficial to the flattening of the sealing film and the arrangement of the edge of the sealing film (when the sealing film is flattened and unfolded to a smaller extent, the edge of the sealing film may be folded, and has a thickness twice or even three times that of the sealing film elsewhere, namely, when the lantern ring 3 is buckled and attached to the slope surface 6, a larger resistance is formed in the relatively thicker area, so that the fixation of the sealing film is influenced). The bottom of the cover 1 is embedded with the lantern ring 3 in an interference manner, so that the lantern ring 3 can be clamped on the sealing film more firmly. The radian of the inner side wall of the lantern ring 3 is matched with the radian of the slope 6 at the bottom of the cover 1, so that good buckling can be realized, and in addition, a rubber layer 7 is arranged on the inner side wall of the lantern ring 3, and the rubber layer 7 can be fixed on the lantern ring 3 in a hot melting or sticking mode. When the lantern ring 3 is buckled on the slope surface 6 (the sealing film is fixed between the lantern ring 3 and the slope surface 6), the diameter of the cross section of the outer side wall of the lantern ring 3 is equal to that of the cross section of the rest positions (except the arc surface 4) of the cover 1, namely, the diameters of the outer sides of the cover 1 and the lantern ring 3 when the cover 1 and the cover 1 are embedded together in an interference manner are the same, the surface is relatively flat, the looseness is not easy to occur under the influence of external force, and if the diameters are different, the moment is easy to form to occur looseness.
The cambered surface 4 is provided with a plurality of through holes 5, and the through holes 5 are communicated with the side wall in the middle of the cover 1 through the inside of the cover 1 and penetrate through the middle of the cover 1. The through hole 5 on the cambered surface 4 directly contacts the sealing film (the aperture of the through hole 5 is not more than 1cm, and the abrasion of the larger aperture to the sealing film is obvious), if the type of the sealing film is a preservative film or a filter membrane, the through hole 5 points to the outer side of the cap 1 through a channel inside the cap 1, and a certain ventilation space is reserved without losing the pressing and sealing of the bottle mouth.
In order to conveniently and artificially open the buckling of the lantern ring 3 and the slope surface 6 and conveniently replace the sealing film, a notch 8 is arranged on the side wall of the outer side of the lantern ring 3, and the lantern ring 3 is pried open by utilizing the notch 8 as a force application point.
The sealing film is fixed under the combination of the lantern ring and the cover to form the sealing cover, in the seed germination experiment, particularly in the watering step, the sealing cover of the bottle mouth is only required to be pulled out, and the bottle is covered after watering (the cambered surface 4 is positioned in the bottle mouth), so that the original complex operation of sealing the film again is greatly simplified, namely, the operation of removing the rubber band adhesive tape and winding a new adhesive tape and a new rubber band is carried out.
In light of the foregoing, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
