PROBLEM TO BE SOLVED: To provide a liquid vessel which is easily formed, and capable of easily selecting, forming and operating opening parts of a small diameter and a large diameter. SOLUTION: The liquid vessel comprises a vessel body 2 having a mouth part 3 to store a liquid, a cap for sealing the mouth part of the vessel body, and a cap cover 5 which is attachably/detachably fitted to a part in the vicinity of the cap or the mouth part of the vessel body. The cap comprises a cap main part 7 fitted to a circumferential edge of the mouth part of the vessel body and having a first opening part 19, a barrel part 8 integrally connected to the first opening part 19 of the cap main part and having a second opening part 20 of the diameter smaller than the diameter of the opening part of the cap main part on an upper part thereof, and a top part 9 integrally connected to the second opening part 20 of the barrel part 8. An integrally connected part 10 of the barrel part 8 with the cap main part 7 is weakened in a dividing manner only by the force application to the barrel part, and an integrally connected part 12 of the top part 9 with the barrel part 8 is weakened in a dividing manner only by the force application to the top part 9. |
