  • condition of releasing the tightly sealed condition means that the condition of the entire peripheral surface of the annular section 121 of cover member 120 being in close contact with the internal circumference surface of the container main body 111 is released. More specifically, it may be sufficient to indicate a change of the condition that the lower surface of the cover member 120 is in contact with the upper surface of the container main body 111 to the condition that these are spaced apart at a predetermined distance.
  • the convex section 122 when the cover member 120 in the condition that the tight seal is released by the changing-direction mechanism 150 is opened with a finger as described above, for example, as shown in FIG. 2 , the convex section 122 is formed from side to side of the cover member 120 , the convex section 122 may be held with the thumb and the middle fingers of a hand that is also employed for holding the container member 110 (not shown).
  • the cover member 120 Even if the cover member 120 is not completely opened by the changing-direction mechanism as described above in such case, the cover member 120 can be easily opened. Moreover, since the finger used for opening the cover member 120 is covered by the convex section 122 , a pollution of such finger with a biochemical substance can be effectively prevented.
  • a robust cylindrical engaging section 263 may be formed in an upper section of an annular section 262 of a cover member 261 , and a multiple-layered seal-like sealing section 264 may be formed in the lower section thereof.
  • the presence of the sealing section 264 ensures a sealability of the cover member 261 .
  • the overall height “a” of the engaging section 263 is selected to be smaller than the distance “b” of the displacement by the changing-direction mechanism 150 , so that an engaging presented by the engaging section 263 can be easily released by the changing-direction mechanism 150 . Consequently, the cover member 261 can be completely opened by the changing-direction mechanism 150 , otherwise ensuring the tight sealing of the cover member 261 .
  • a concave section 273 having a triangle cross-sectional geometry may be formed in a peripheral surface of a bottom end of an annular section 272 of a cover member 271 , and a convex section 274 , which engages with such concave section 273 , may be formed inner circumference surface of a container member 275 .
  • a displacement “c” required for releasing the engage of the concave section 273 with the convex section 274 is selected to be smaller than the distance “b” of the displacement by the changing-direction mechanism 150 , so that an engaging of the concave section 273 with the convex section 274 can be easily released by the changing-direction mechanism 150 . Consequently, the cover member 271 can be completely opened by the changing-direction mechanism 150 , otherwise ensuring the tight sealing of the cover member 271 .
  • the above-described embodiment illustrates that the changing-direction mechanism 150 is located in the side opposite to the hinge mechanism 130 , so that an end of the cover member 120 is displaced by a single changing-direction mechanism 150 to open thereof.
  • a pair of changing-direction mechanisms 150 may be formed from side to side.
  • a pair of assisting-opening members 140 are pressed from both sides with the thumb and the first finger in the condition that the container main body 111 is held in one hand, so that the right and the left edges of the cover member 120 are simultaneously displaced in the upward direction by a pair of changing-direction mechanisms 150 to open thereof.
  • the assisting-opening member 140 of the cover member 120 can be held with a finger of another hand. Therefore, a pollution of the finger that opens the cover member 120 with a biochemical substance can be prevented by utilizing the assisting-opening member 140 as a cover.
  • the above-described embodiment illustrates that the bottom end section 141 of the assisting-opening member 140 connected to the cover member 120 is in contact with the upper half section of the convex section 162 of the container member 110 to cause a displacement to achieve the changing-direction mechanism 150 .
  • an end of an assisting-opening member 291 curved outward to form an arc-like shape may be connected to one of a cover member 292 and a container main body 293 , and the other end may be engaged with a convex section 294 of the other thereof to achieve a changing-direction mechanism 295 .
  • the cover member 292 can be separated from the container main body 293 by such elongation to open thereof.
