PROBLEM TO BE SOLVED: To provide a nozzle head cover preventing unscrewing of a nozzle head screwed in a pushed-down state to a fitting cylinder fitted to a mouth of a container body filled with content liquid.SOLUTION: A nozzle head cover 1 includes a top wall 2, and a lateral wall 3 suspended from the top wall 2 to surround at least a semi-circular area of a nozzle head 13, and having, at the front side, a nozzle housing section 4 for housing a nozzle 14. The lateral wall 3 has: an engagement piece 3 formed from a pair of upper and lower slits 6 extending forward from an opening 5 for detaching from the nozzle head 13, and engaging and holding the nozzle head 13; and a flange 8 projecting from a lower end of the lateral wall 3 to a radial direction inner side and engaged with a lower end surface 12a of a fitting cylinder 12. The top wall 3 has a support section 9 brought into contact at first with the upper surface of the nozzle head 13 in a process that the nozzle head 13 is unscrewed from the fitting cylinder 12, and a contact position contacting at first with the upper surface 13a of the nozzle head 13 in the support section 9 is located at a forward side of a front edge 6a of the slit 6.SELECTED DRAWING: Figure 1 |
