Description

[Detailed explanation of the idea] "Industrial application field" This proposal concerns a cap with a spout.

``Prior art'' As this kind of cap, for example,
The invention disclosed in Publication No. 16276 is known. In the cap of the present invention, a fitting tube part that fits into the inner surface of the mouth and neck is suspended from the lower surface of the side wall that closes the top surface of the mouth of the container body, and a hole with a bottom is provided in the eccentric part of the side wall, and a hole with a bottom is provided in the eccentric part of the side wall. A mouth and neck attachment member having a through hole drilled at an eccentric position, a spouting member that projects a nozzle laterally from the upper end of a shaft cylinder rotatably fitted into the hole, and a spouting member that allows the nozzle to slide freely. The lower half of the peripheral wall with a window hole inserted therethrough and hanging from the outer periphery of the top wall is rotatably fitted to the outer surface of the mouth and neck, and the window hole is inserted through the cover and is rotatably fitted to the outer surface of the mouth and neck. The nozzle tip can go in and out from the window hole, and the lower end of the cylindrical hole of the shaft cylinder communicates with the through hole in a state where the nozzle tip protrudes the longest outward from the window hole, and the nozzle tip is housed in the window hole. In the closed state, the lower end surface of the shaft cylinder closes the through hole.

``Problems to be solved by the invention'' In the conventional cap described above, the nozzle tip moves in and out of the cover surrounding wall when the cover rotates relative to the container body, so it is necessary to prevent the container body from rotating in order to rotate the cover. Therefore, it is difficult to operate the nozzle in and out with only one hand.

The present invention allows the nozzle to be moved in and out by simply pushing down the operating head corresponding to the cover, making the nozzle insertion and removal operation extremely simple.

"Means for Solving the Problem" A nozzle is formed coaxially with the guide tube 6 by a plurality of support pieces 7 protruding inward from the inner surface of the guide tube 6 which is fitted and fixed to the neck 3 of the container body and extends upward. Fix 8,
and an upper part spaced apart vertically from the outer surface of the upper half of the guide tube 6;
Lower engaging protrusions 9 and 10 are provided around the circumference, and a floating ring 11 having the same outer diameter or a larger outer diameter as the engaging protrusions is loosely fitted below the lower engaging protrusions 10 so as to be movable up and down. A support piece 7 is inserted between the nozzle 8 and the guide tube 6 from the back surface of the top wall 15, which has a hole in the center thereof into which the upper end of the nozzle 8 is fit vertically.
The inner circumferential wall 8 has a first vertical groove inserted therethrough, and the engaging protrusion 20 that is engaged with the upper engaging protrusion 9 is formed on the inner periphery of the lower end of the cylinder having a plurality of second longitudinal grooves 19. An elastic circumferential wall 17 is attached and fitted onto the outer surface of the guide cylinder 6, and is fixed to the operating head 4, which is biased upwardly by a spring 21 so as to be able to descend and return, and to the lower end of the inner circumferential wall 18. An annular body 22 that moves up and down between the nozzle 8 and the guide tube 6 in a liquid-tight manner.An inverted L-shaped engagement piece 24 protrudes radially from a plug body 23 that seals the lower end opening of the nozzle 8 to the lower surface thereof. When the engagement protrusion 20 engages with the lower engagement protrusion 10 by pressing down the operation head 4, the lower end surface of the nozzle opens, and by further pressing down, the engagement protrusion 20 closes to the floating ring 11. Climb onto the outer surface,
The floating ring was formed so as to be able to be pulled up.

``Operation'' When the operating head 4 is pushed down from the closed state of the lower end of the nozzle 18 shown in FIGS. The strip 20 is the lower engagement protrusion 10 of the guide tube 6
The plug body 23 is engaged with the lower surface, and the plug body 23 is separated downward from the lower end surface of the nozzle 8 to open the nozzle hole. Therefore, in this state, the liquid inside the container can be poured out from the nozzle 8.

In order to close the nozzle hole again, the operating head 4 is further pushed down from the third state. Then, the engagement protrusion 20 rides on the outer peripheral surface of the floating ring 11 and clamps the ring. By the way, since the floating ring is fitted to the lower part of the lower engagement protrusion 10 of the guide cylinder 6 so as to be able to move up and down, and since the operating head 4 is urged upward by the coil spring 21, the operating head 4 cannot be operated. The head 4 rises while holding the floating ring 11, and as shown in FIG. 4, the ring stops when the upper end of the floating ring 11 engages with the lower surface of the lower engaging protrusion 10. Then, the engagement protrusion 20 comes off from the outer surface of the ring, and after passing through the lower engagement protrusion 10, due to the elastic recovery of the elastic peripheral wall 17, it engages with the lower surface of the upper engagement protrusion 9 as shown in FIG. At this time, the stopper 23 seals the lower end surface of the nozzle 8.

``Example'' 1 is a mouth attachment member attached to the mouth and neck part 3 of a container body 2, 4 is a cap-shaped operation head that is fitted into the mouth attachment member 1 so as to be able to be pushed down, and 5 is an operation head for this operation. It is a plug member that moves up and down together with the head, and each of these parts is molded and manufactured from a synthetic resin material.

The mouth attachment member 1 has a lower portion fitted into the mouth neck 3 of the container body, and a plurality of support pieces 7 protruding inward from the upper inner surface of the guide tube 6 extending upward from the mouth neck 3.
The nozzle 8 is fixed coaxially with the guide cylinder. In addition, an upper engagement protrusion 9 is provided on the outer surface of the upper end of the upper half of the guide tube 6.
A lower engagement ridge 10 is provided around the lower engagement ridges 10, and a floating ring 11 which can be raised and lowered is loosely fitted slightly below the lower engagement ridge 10. By engaging the engagement protrusion 13 on the inner periphery of the fitting peripheral wall 12 that hangs down from the lower part of the guide cylinder 6 to the top surface of the mouth of the container body, and engaging the engagement protrusion 14 on the outer periphery of the mouth and neck part 3, Prevents removal from the mouth and neck. Note that the floating ring 11
is selected so that its outer diameter is the same as or slightly larger than the outer diameter of the lower engagement protrusion 10.

The operation head 4 has a hole bored in the center of the top wall 15 into which the upper end of the nozzle 8 is fitted vertically, and from the back side of the top wall 15 to the external peripheral wall 16 and the mouth mounting member 1. An intermediate elastic circumferential wall 17 that fits on the outer surface of the guide tube 6 and a first longitudinal groove (not shown) passing through the support piece 7 are formed to form an inner circumferential wall 18 vertically between the guide tube 6 and the nozzle 8. The elastic peripheral wall 17 is provided with second grooves 19 in the circumferential direction extending from the lower end to the upper part so as to be able to expand against the elasticity of the grooves. A mating protrusion 20 is provided in a protruding manner and is always urged upward by a coil spring 21.

The plug member 5 is fixed to the lower end of the inner circumferential wall 18 and moves up and down between the guide cylinder 6 and the nozzle 8 in a liquid-tight manner, from the plug member 23 that closes the lower end opening of the nozzle 8 from below to the lower surface of the annular body 22. Multiple inverted L's protruding radially
The tip of the shaped connecting piece 24 is fixed.

In the above structure, the operating head 4 is normally pushed upward by the spring 21 as shown in FIGS.
3 seals the lower end opening of the nozzle 8. By pressing down the operating head from this state, the engagement protrusion 20 at the lower end of the elastic peripheral wall 17 engages with the lower surface of the lower engagement protrusion 10 as shown in FIG. 20 is provided so as to be able to ride on the outer peripheral surface of the floating ring 11.

``Effect of the invention'' The present invention has the above-described structure, and as described in the operation section, the nozzle hole is opened by simply pushing down the operating head 4 against the container body, and the nozzle hole is opened. By simply pressing the operating head further down, the operating head rises and closes the nozzle hole, making it extremely easy to open and close the nozzle hole.
