The specific embodiment

As Fig. 2 and shown in Figure 3, the utility model Buffer bottom cover 3 embodiment are used to seal the bottom of a tank body 2 with packing one bottle container 20, described tank body 2 has a surrounding wall 21, an and ring flange 22 that is positioned on these surrounding wall 21 bottom inner peripheral surfaces, this Buffer bottom cover 3 comprises: a horizontal bottom wall 31, one by the upwardly extending leg 32 of these diapire 31 peripheries, plural number is spaced in affixed 33 of this diapire 31 end faces, one by these leg 32 upper limbs outside buffer wall 34 of extending of bending flexiblely, one by the downward engaging wall 35 that extends of these buffer wall 34 outer peripheral edges, one is positioned at these engaging wall 35 outer peripheral faces and cutting ferrule in the annular groove 36 of described tank body 2 flanges 22, and plural number is between left and right every being arranged in these engaging wall 35 outer peripheral faces and being positioned at the groove 37 of these annular groove 36 tops.

This diapire 31 defines an accommodation space 38 jointly with this leg 32, to be installed in the bottom of described bottle container 20.These affixed 33 summary is spaced triangular in shape and radially and is fixed on this diapire 31, and utilizes these hypotenuses of affixed 33 to abut against in the bottom of described bottle container 20 periphery to be fixed in this accommodation space 38.These shapes of affixed 33 also can be made into as shown in Figure 4 L shaped shape being sticked in the bottom of bottle container 20, so practical range does not exceed with above-mentioned shape.

As shown in Figures 3 and 4, this buffer wall 34 connects the upper limb of this leg 32 and this engaging wall 35, because of itself shape becomes circular arc bending and thinner thickness to have the characteristic of elastic deformation, when making this Buffer bottom cover 3 be subjected to side or bottom surface bump, this buffer wall 34 can come the impulsive contact force of buffering collision of closed as illustrated in fig. 5 with the elastic deformation of this body structure, avoid impulsive contact force to destroy described bottle container 20.

The outer peripheral face of this engaging wall 35 is that summary is tiltedly had a down dip outward by last, the outer peripheral face that just engages wall 35 first halves is the inclined-plane under tiltedly outward, and the thickness of its lower part is thick than first half thickness, increasing the rigidity of this engaging wall 35, and this annular groove 36 is exactly to be positioned on the lower part outer peripheral face of this engaging wall 35.
