It is continuously bent and folded into a substantially wave shape.

  Next, the operation of the straw cap 1 having the above-described configuration will be described.

  When the cap 1 with a straw is not used (for example, when it is distributed or carried), as shown in FIG. 1, the straw storage chamber is in a state where the lower portion (second tube 31) of the straw 3 is folded (shortened state). The bottom cover 4 is screwed to the lower end of the storage cylinder portion 62 and the lower end of the straw storage chamber 69 is closed. Further, the lid 56 is closed and the opening 51a of the upper wall portion 51 is closed, and the upper portion (first tube 30) of the straw 3 is substantially S-shaped by the first and second engaging portions 57 and 59. And is accommodated in the upper wall portion 51 in a bent state. As described above, the straw cap 1 is formed in a substantially spherical shape as shown in FIGS.

  On the other hand, when using the cap 1 with a straw, as shown in FIG. 3, the bottom cover 4 is first removed from the storage cylinder part 62, and the lower end of the straw storage chamber 69 is opened. More specifically, the knob 42 of the bottom cover 4 is picked with a finger or the like, the bottom cover 4 is rotated around the axis O relative to the cap body 2 (tubular portion 60), and the storage cylinder portion The bottom cover 4 screwed to the lower end of 62 is removed. Accordingly, the second tube 31 stored in the straw storage chamber 69 in a folded state is restored by elasticity, and the lower portion of the second tube 31 protrudes from the lower end of the straw storage chamber 69. At this time, when the second tube 31 is not completely restored due to close contact or the like, the lower portion of the second tube 31 is pulled downward to extend the second tube 31.

  Next, the bottom lid 4 removed from the storage cylinder 62 is placed in a lateral orientation, that is, in a posture in which the center axis of the bottom lid 4 is orthogonal to the axis O of the cap body 2. It is inserted into the bottom lid storage chamber 67 from the lower part of the opening 61 a and is stored in the bottom lid storage chamber 67. At this time, when the bottom cover 4 is inserted into the opening 61a, the regulation plate 68 disposed in the opening 61a is pressed from the inside of the bottom cover storage chamber 67 by the bottom cover 4 and elastically deforms toward the outside. After that, when the bottom cover 4 is stored in the bottom cover storage chamber 67, it is restored to its original position by elasticity. Thus, the regulation plate 68 prevents the bottom lid 4 in the bottom lid storage chamber 67 from coming out. Further, the bottom cover 4 stored in the bottom cover storage chamber 67 is locked by the inner surface of the bottom cover storage chamber 67. More specifically, the knob 42 of the bottom cover 4 is locked to the outer peripheral surface (tapered surface 65b) of the peripheral wall 65 of the mounting cylinder 63, and the opening edge of the mounting 41 of the bottom cover 4 is defined. The outer cylindrical portion 52 is engaged with the inner peripheral surface. Accordingly, the bottom lid 4 is locked at two positions that are symmetric with respect to the center of gravity of the bottom lid 4, so that the bottom lid 4 is reliably held in the bottom lid storage chamber 67.

  Next, the cylindrical part 60 is attached to the mouth part 11 of the container 10. More specifically, first, the lower part of the second tube 31 extended as described above is inserted into the container 10 from the mouth portion 11 of the container 10. And after putting the mounting cylinder part 63 on the upper end part of the opening part 11, the container 10 and the cap 1 with a straw are rotated around the axis line O relatively, and the internal thread of the mounting cylinder part 63 is made to the male screw 11a of the opening part 11. The mounting cylinder portion 63 is screwed into the mouth portion 11 by screwing 65a. Thereby, the cap 1 with a straw is fixed to the mouth part 11 of the container 10 and the lower end part of the straw 3 is disposed in the container 10. At this time, it is preferable that the lower part of the storage cylinder part 62 (the penetrating part protruding downward from the inside of the top wall part 64 of the mounting cylinder part 63) is in close contact with the inner peripheral surface of the mouth part 11. Thereby, the lower part of the storage cylinder part 62 functions as an inner seal, and the sealing performance of the mouth part 11 is improved.

  Next, the lid body 56 of the upper wall portion 51 is opened to open the opening 51 a of the upper wall portion 51. More specifically, a finger or the like is put on the flange portion 56b of the lid 56 and pushed up. Thereby, the latching | locking part 56c of the cover body 56 remove | deviates from the latching | locking part 50b of the top wall part 50. FIG. Then, the lid body 56 is rotated around the hinge 56a to open the lid body 56. Thereby, the plug part 58 is pulled out from the air hole 50a, and the air hole 50a is opened. Further, the distal end of the second engaging portion 59 is separated from the top wall portion 50, and the lid body 56 is separated from the distal end of the first engaging portion 57, and is substantially S by the first and second engaging portions 57, 59. The upper part (first tube 30) of the straw 3 bent in a letter shape is restored by elasticity and protrudes obliquely upward from the through hole 54b of the straw holding part 54 toward the front side. At this time, if the first tube 30 is not completely restored due to close contact or the like, the upper portion of the first tube 30 is pulled to extend the first tube 30.

  By the above, the cap 1 with a straw becomes a usable state, and it becomes possible to drink the contents in the container 10 with the cap 1 with a straw. That is, the contents in the container 10 are sucked from the lower end of the straw 3 (second tube 31) by sucking the upper end of the straw 3 (first tube 30) protruding above the top wall 50. It is sucked up through the straw 3. At this time, the outside air flows into the straw storage chamber 69 through the air hole 50 a of the top wall portion 50 and the through hole 33 a of the flange portion 33 of the straw 3. Since the lower end of the straw storage chamber 69 is open toward the container 10, the contents and air are replaced in the container 10. Thereby, the decompression in the container 10 at the time of sucking and drinking the contents is suppressed, and the contents are sucked up easily.

  Moreover, after using the cap 1 with a straw, the cover body 56 is first rotated around the hinge 56a and closed. Accordingly, the upper portion of the straw 3 is accommodated in the upper wall portion 51 in a state of being bent in a substantially S shape by the first and second engaging portions 57 and 59, and the first and second engaging portions. 57 and 59 are crushed and sealed.

Next, the cap body 2 is removed from the mouth portion 11 of the container 10. More specifically, the cap main body 2 and the container 10 are relatively rotated about the axis O, and the male screw 11a of the mouth portion 11 and the female screw 65a of the mounting cylinder portion 63 are unscrewed and attached from the mouth portion 11. The cylinder part 63 is removed.
Next, the bottom cover 4 is taken out from the bottom cover storage chamber 67. More specifically, the bottom lid 4 in the bottom lid storage chamber 67 is picked by a finger or the like and pulled out from the opening 61a of the outer wall portion 61. At this time, the regulation plate 68 is pressed by the bottom lid 4 from the inside to the outside of the bottom lid housing chamber 67 and elastically deforms. Thereby, the bottom lid 4 is easily pulled out from the bottom lid storage chamber 67.

  Next, the lower part (second tube 31) of the straw 3 is stored in the straw storage chamber 69, and the straw storage chamber 69 is closed with the bottom cover 4. Specifically, the lower portion (second tube 31) of the straw 3 is folded and reduced to be put into the storage cylinder portion 62. Then, the bottom lid 4 taken out from the bottom lid storage chamber 67 is screwed to the lower end portion of the storage cylinder portion 62 to close the lower end of the storage cylinder portion 62, and the folded second tube 31 is pressed by the bottom lid 4. . Thereby, the cap 1 with a straw returns to the original substantially spherical shape shown in FIG.

  When the lower part of the straw 3 is difficult to fold, the first member 5 and the second member 6 are once separated, and the lower part of the straw 3 is pulled out from the straw storage chamber 69. Then, after attaching the bottom lid 4 to the lower end of the storage cylinder 62, the second tube 31 is folded while the second tube 31 is inserted into the straw storage chamber 69 from the upper end of the storage cylinder 62, and the first member 5 is folded. Is assembled to the second member 6 again. Thereby, the 2nd tube 31 becomes easy to fold and the operation | work which accommodates in the straw storage chamber 69 in the state which reduced the 2nd tube 31 becomes easy.

  Moreover, when wash | cleaning the cap 1 with a straw, the 1st member 5 and the 2nd member 6 are isolate | separated.
