The container body must be formed in a complicated shape that is formed on the small outer diameter portion and the mouth and neck portion is erected from the upper end of the small outer diameter portion via the shoulder portion. The cover cylinder covering the upper end must also be formed in a complicated shape in order to be locked to the container body, which raises the problem of increased manufacturing costs, and is separately treated to remove the cover cylinder from the container body. There is a problem that it is necessary to prepare and store the tool, which increases the cost, and forgets where to store the jig or loses the jig.

  The object of the present invention is to solve such problems, and it is not necessary to change the shape of the container body itself in order to attach a protective cap for preventing the vertical pump from being removed from the container body. The container body can be used, the shape of the protective cap is simple and the cost can be reduced, and further, no jig for moving the protective cap is required to expose the cap for mounting. In this case, only a specific person moves the protective cap without using a jig so that the cap for mounting is exposed.

  According to a first aspect of the present invention, a liquid discharge container includes a container body, a mounting cap that is screwed to the outside of the upper end opening of the container body, and an upward direction from the mounting cap through the cylinder portion. A projecting push-down head, a pump provided with a nozzle that discharges liquid by a push-down operation of the push-down head, and a flexible protective cap that covers the mounting cap. A hole that covers the upper surface and the peripheral surface and through which the cylindrical portion penetrates is formed at the center of the upper end, and two small mark portions are formed on the lower end surface of the protective cap in two portions in the circumferential direction. A claw piece to be engaged with the lower end surface of the mounting cap is formed at a position between the two mark portions, and further, the inner surface of the protective cap is at a position between the mark portion and the claw piece. Installation key Wherein the the outer surface of the-up has longitudinal ribs abut is formed.

  As described above, the liquid discharge container according to the present invention does not need to change the shape of the container body in order to attach the protective cap for preventing the vertical pump from being removed from the container body, and uses the container body having an existing shape. In addition, the shape of the protective cap is simple and the cost can be reduced. In particular, there is no need for a jig to move the protective cap to expose the cap for mounting, and only a specific person does not use a jig to protect the cap by deforming the protective cap by picking the mark on the protective cap. It is possible to provide a liquid discharge container in which the pump can be removed from the container body by lifting the cap from the mounting cap and picking and rotating the exposed mounting cap.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS.
In the figure, reference numeral 1 denotes a container body in which a pump 3 is attached to a mouth 2 at the upper end, and a liquid such as a liquid detergent is placed inside the container body 1. The pump 3 includes a mounting cap 5 screwed into a male screw portion 4 formed on the outer periphery of the upper end opening 2 of the container body 1, a push-down head 6 protruding upward from the cap 5, and the push-down head 6. It is comprised from the nozzle 7 etc. which protrude from the side. More specifically, the pump 3 includes a downward cylindrical portion 9 that is press-fitted from above into a cylindrical portion 8 that protrudes upward from the center of the cap 5 below the push-down head 6, and presses the cylindrical portion 9 into the cylindrical portion 8. In this state, a stepped portion 11 is formed on the push-down head 6 so as to cover the upper end of the cylindrical portion 8. The lower end of the cylindrical portion 10 formed on the outer side of the cylindrical portion 9 and the outer peripheral surface of the cylindrical portion 8. The pump 3 is configured to suck up the liquid inside the container body 1 by pushing the push-down head 6 and discharge the liquid from the nozzle 7, and the internal mechanism is well known, so that detailed description is omitted. Further, the material of the container body 1 and the pump 3 is made of synthetic resin except for one part material such as a spring (not shown) built in the pump 3.

  Next, 12 is a flexible protective cap made of synthetic resin that covers the mounting cap 5 from above and covers the mounting cap 5 from the outside. This protective cap 12 is an upper surface of the mounting cap 5. A hole 13 is formed at the center of the upper end so as to cover the peripheral surface and through which the cylindrical portion 8 passes, and two small mark recesses 14 are formed on the lower end surface of the protective cap 12 at a position equally divided in the circumferential direction. In addition, two claw pieces 15 are formed on the lower end surface of the mounting cap 5 at a position where the space between the two mark recesses 14 is equally divided. 4 are formed with four vertical ribs 16 that come into contact with the outer surface of the mounting cap 5 at a position where the gap between the mark recess 14 and the claw piece 15 is divided into two equal parts. That is, since the protective cap 12 is in contact with the outer surface of the mounting cap 5 at the position of the rib 16, the protective cap 12 is located between the inner surface of the protective cap 12 and the outer surface of the mounting cap 5 at a location where the rib 16 does not exist. A gap is formed. The inner diameter of the hole 13 is slightly larger than the outer diameter of the cylindrical portion 8 and smaller than the outer diameter of the cylindrical portion 10.

  In the above configuration, in order to attach the protective cap 12 so as to cover the upper surface and the peripheral surface of the mounting cap 5, the upper side from the mounting cap 5 screwed into the male screw portion 4 of the upper end opening 2 of the container body 1. Before the cylindrical portion 9 is press-fitted into the cylindrical portion 8 projecting into the cylindrical portion 8, the protective cap 12 is put on the mounting cap 5, and the claw piece 15 is locked to the lower end surface of the mounting cap 5, and in this state, the cylindrical portion The cylinder portion 9 is press-fitted into the portion 8 to assemble the pump 3.

  FIGS. 3 and 4 show a liquid discharge container in which a cap 5 for mounting is covered with a protective cap 12. Even if the pump 3 is removed from the container body 1 of the liquid discharge container, the cap 5 for mounting is the protective cap 12. In the state covered with, the mounting cap 5 cannot be turned and loosened, and the pump 3 cannot be removed. When a specific person who knows how to remove the pump 3 from the container body 1 removes the pump 3 from the container body 1 to replenish the liquid in the container body 1, the protective cap 12 faces 2 The lower end of the protective cap 12 swells at the position where the claw piece 15 is formed by picking the lower end of the protective cap 12 against the outer surface of the mounting cap 5 at the position of the mark concave portion 14. The claw piece 15 comes off from the lower end surface of the cap 5 for mounting, and the protective cap 12 can be lifted from the cap 5 for mounting. The protective cap 12 lifted from the mounting cap 5 is made so that the upper end abuts on the step portion 11 and the lower half of the mounting cap 5 is exposed in this state. The pump 3 can be removed from the container body 1 by picking and turning the cap 5.

  In the embodiment shown in the drawings, the protective cap 12 lifted from the mounting cap 5 is made so as to abut on the stepped portion 11, but between the push-down head 6 and the mounting cap 5. The protective cap 12 can also be provided in a pump having a straight tube portion. Further, a mark recess 14 is formed on the lower end surface of the protective cap 12 to mark a position to be picked to deform the protective cap 12 when the protective cap 12 is lifted from the mounting cap 5. A small mark or the like may be provided.
