Title: Pot cover structure

Description:
FIELD OF THE INVENTION  
       [0001] This invention relates to the structure of a pot cover, and more particularly, to a pot cover that can seal with the pot firmly.  
       BACKGROUND OF THE INVENTION  
       [0002] There are many pots of different designs on the market. A conventional pot is made of ceramic or glass with a wall extending downwardly from the center bottom portion of the cover, with at least two holes equally spaced from each other, and an elastic ring in the wall, the elastic ring is formed with bulging areas corresponding to the holes and extending outwardly from the holes, so that when the cover covers the pot, a portion of which exposed outwardly from the hole and engaging with the pot.  
       [0003] This conventional design of cover can hold the pot firmly, however, due to the strength of the elastic ring, the cover is hard to pull away, further, when pushing the cover onto the pot, if the pushing force is applied to hard, the pot mouth or the cover may be broken.  
       SUMMARY OF THE INVENTION  
       [0004] It is the primary object of the present invention to provide a renovated structure of a pot cover, which buffers the movement of the cover from pushing into and pulling away of the pot, so as to reduce possibility of breaking the pot or the cover.  
       [0005] It is another object of the present invention to provide a renovated structure of a pot cover, which is easy to operate.  
       [0006] It is a further object of the present invention to provide a renovated structure of a pot cover, which is safe in use.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
     [0014] The renovated structure of a pot cover of the present invention comprises a cover  1 , and a number of clips  2 .  
     [0015] The cover  1  is made of either ceramic or glass material, having an edge  11  extending downwardly from center of the cover, a number of holes  111  being formed on the edge  11  and equally spaced from each other, a wall  12  being formed along the edge  11  towards the center portion of the cover  1  with holes  121  thereon.  
     [0016] The clip  12  is made of plastic material, has a stop section  21  at the top portion thereof, a contact section  22  at the center portion and protruding outwardly there from, a block  23  being formed at the bottom portion and a pair of clipper edges  24  extending upwardly from the block  23  and in parallel with each other.  
     [0017] To assemble the present invention, each of the clips  2  is inserted into the relative hole  111  of the cover  1  with the clip edge  24  inserted into the relative hole  121  all the way to its bottom end of the hole, as shown in FIG. 2, the block  23  is placed against the hole  121  and engaged with the edge of the wall  12 . At least two clips  2  are placed on the wall  12 , thus the cover  1  of the present invention is formed.  
     [0018] When closing a pot  3  with the cover  1 , as shown in FIGS. 3 and 4, a mouth  31  of the pot  3  is formed with a smaller diameter at its neck  32 , and then gradually enlarging at its body  33 . When enclosing the cover  1  to the pot  3 , the contact section  22  of the clip  2  of the cover  1  will engage with the inside of the neck  32 , which presses the contact section  22  inward and allows the cover  1  to be in touch with the neck  32  direct, upon the clip  2  passes through the neck  32 , the contact section  22  returns to its original position and engages with the lower end portion of the neck  32 . To open the cover  1 , the cover  1  is pulled up, which will bring the contact section  22  of the clip  2  slide through the neck  32  of the pot  3 , which squashes the contact section  22  inwardly and returns to its original position till they pass the neck  32 .  
     [0019]FIG. 5 shows a second embodiment, a clip  4  is made of metal material, the clip  4  comprises a stop section  41  bending outwardly from the top portion of the clip  4 , a contact section  42  bending outwardly from the center portion, and a buffer section  43  extending downwardly from the contact section  42 , a block  44  extending from the endmost of the buffer section  43 , and a pair of clipper edges  45  on the block  44 . The bending degree of the buffer section  43 , between the contact section  42  and the block  44 , is adjustable depending on the distance between the cover  1  and the pot neck  32 . When closing the cover  1  onto the pot  3 , as shown in FIGS. 6 and 7, the stop section  41  of the clip  4  buffers the pressing force of the cover  1  against the pot  3 , upon the contact section  42  passes the neck  32  of the pot  3 , the contact section  42  returns to its original position and engages with the lower end of the neck  32 , thus the cover  1  is held at place.  
     [0020] In this embodiment, the bending format of the clip  4  depends on the distance between the cover  1  and the pot  3 , this shall leave no space between the cover  1  and the pot  3 .  
     [0021] Therefore, the cover  1  of this design has at least two clips  2  or  4 , equally spaced from each other along the wall  12  of the cover  1 , so that they may engage with the mouth  31 , evenly, which is helpful both in open and close of the cover  1 .
