For example, as shown in FIG. 4, the circular pipe member 17 and the partition plate 13 are formed by integral molding, and the circular pipe member 17 is an extended portion that extends from the attachment portion 16 toward the sealing cap 10. In this way, the attachment portion 16 and the circular pipe member 17 are connected.
  • the circular pipe member 17 includes an engagement portion 19 at the distal end located on the sealing cap 10 side, and the closing portion 12 is engaged with the engagement portion 19 on the inner peripheral surface on the distal end side protruding into the space 5.
  • the engaged portion 20 is provided.
  • the closing portion 12 and the circular pipe member 17 are connected by the engagement between the engaging portion 19 and the engaged portion 29. That is, the joint location can be reduced by using integral molding instead of joining the two members, and by using engagement, it can be easily connected and fixed by adhesion, welding, or the like, and the assemblability of the water purification cartridge 1 can be improved.
  • the engaging portion 19 is provided as an engaging claw having elasticity, and the engaging claw is hooked on the closing portion 12, so that the closing portion 12 and the circular tube member 17 may be connected and fixed.
  • the engaged portion may be provided in the circular pipe member 17, and the engaging portion may be provided in the closing portion 12.
  • a thread groove (not shown) is formed on the inner peripheral surface on the distal end side of the closing portion 12, and a screw thread (not shown) is formed on the outer peripheral surface on the distal end side of the circular tube member 17, The circular tube member 17 may be screwed into the closed portion 12 so that the closed portion 12 and the circular tube member 17 are connected and fixed.
  • the attachment part 16 and the circular pipe member 17 may be joined by engagement, or the sealing cap 10 and the circular pipe member 17 may be integrally formed.
  • the sealing cap 10 does not include the closing portion 12 but includes only the sealing portion 11, and the circular tube member 17 has a front end flush with the first end surface 8. 4 is formed to be longer than the circular pipe member 17 illustrated in FIG. 4, and the outer peripheral surface on the front end side of the circular pipe member 17 is bonded to the inner peripheral surface 7 of the molded activated carbon 4 to seal the front end of the extended circular pipe member 17.
  • the part 11 may be joined. That is, in this configuration, the extended portion of the circular pipe member 17 functions as the closing portion 12 of the sealing cap 10 described above.
  • the partition plate 13 does not include the mounting portion 16 but includes only the main body plate 14, and the tip of the circular pipe member 17 extended so as to be flush with the second end surface 9 and the partition plate 13.
  • the contact surfaces may be integrated by bonding.
  • the knob 21 is provided on the outer side in the axial direction C of the sealing portion 11 of the sealing cap 10, so that the operator can directly apply the molded activated carbon 4 when the water purification cartridge 1 is replaced.
  • the water purification cartridge 1 can be attached and detached without touching. That is, when the new water purification cartridge 1 is attached, it is possible to prevent the operator's hand, pliers, etc. from touching the molded activated carbon 4 to attach the oils and fats of the hand or damage the molded activated carbon 4. And when removing the water purification cartridge 1 which became old, it can prevent that an operator's hand and pliers touch the impurity adhering to the shaping
  • the knob portion 21 has an insertion hole 22 that penetrates in a direction orthogonal to the axial direction C, and includes a hook or the like when the water purification cartridge 1 is removed from the filtration portion 45.
  • the water purification cartridge 1 can be removed by inserting and hooking an attachment / detachment jig (not shown) into the insertion hole 22. And since the said jig
  • the sealing cap 10 provided with the knob portion 21 is connected and fixed to the partition plate 13 via the circular tube member 17 described above, so that when the water purification cartridge 1 is held by the knob portion 21, an external impact is applied. Therefore, it is preferable that the sealing cap 10 can be reliably prevented from coming off the molded activated carbon 4 and the safety can be further improved.
  • the knob 21 is not limited to one that is concentric with the molded activated carbon 4 and protrudes into a cylindrical shape or a prismatic shape, but is an annular shape that protrudes concentrically with the sealing portion 11 or the radial direction of the sealing portion 11.
  • a non-slip portion (not shown) such as a groove or an unevenness is provided on the outer surface such as the peripheral surface or the side surface of the knob 21. That is, when the operator picks the knob 21, even if the knob 21 is wet with water or the like, the anti-slip portion can prevent the finger or pliers from slipping.
