BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dispensing cap.

[0002]

[Prior art]

[Problem to be solved by the invention]
A cap body having a top wall that closes the top opening of the mouth and neck extended from the top edge of the peripheral wall fitted to the outer periphery of the mouth and neck of the container body, and a pouring cylinder portion standing upright at the center of the top wall; Is openably and closably provided, and a lid body is provided which has a stick plug which is fitted and closed from the back surface of the top wall to the above-mentioned injection tube portion.

[0003] These can be formed by integral molding of a synthetic resin. Even though the structure is simple, good sealing properties can be obtained only by closing the lid, and the liquid in the container can be poured simply by opening the lid. It is convenient to be able to take out, but there is a limit on the width of the protrusion of the pouring cylinder. That is, if the projecting width of the pouring cylinder portion is increased, the height of the lid must be increased accordingly, which not only wastes material but also degrades the appearance. Also, if there is an extra protruding portion, extra space is required when it is attached to the container, which hinders transportation and storage.

The present invention solves the above-mentioned drawbacks of the prior art. When not in use, the protrusion width is reduced as much as possible so that it is not bulky. The present invention proposes an excellent dispensing cap that can be easily dispensed and can be opened and closed by a simple one-touch operation.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a cap according to the present invention is a pouring cap integrally formed of a synthetic resin, and has a central portion from an upper end edge of a peripheral wall 4 to be fitted to a mouth and neck of a container body. A top wall 5 having a bulged portion 6 having a protruding width approximately equal to the wall thickness is extended, and a window hole 8 having a deformed rectangular shape whose front side is arc-shaped is formed in the center of the front end of the bulged portion 6. The mounting part 2 includes a perforated mounting part 2 and a pouring part 3 protruding above the mounting part top wall 5 and communicating with the mounting part 2 through a window 8. Is a pouring cylinder 9 having a front lower end connected to the center of the front side of the window hole 8 and standing upright.
A lid plate 10 which is connected to the rear side of the window hole 8 so as to be rotatably connected to a lower end edge thereof, and which rises upward; The stopper 11 is an inclined surface that descends rearward, the window hole 8 is closed with the periphery of the window hole 8 and the lower edge of the stopper 11 as a peripheral edge, the upper part of the discharge tube 9 is projected, and A reversing wall 12 for elastically reversing the top and bottom of the wall 5. When the reversing wall 12 is inverted downward, the top end of the pouring cylinder 9 which is tilted backward and reclined forward with the tip of the injection cylinder 9 reclined rearward. And the rear portion of the cover plate 10 is fitted into the window hole 8.

[0006]

When the cap 1 in the state shown in FIG. 1 is mounted on the container body A and the cover plate 10 is tilted forward, the reversing wall 12 is elastically reversed below the mounting portion top wall 5 as shown in FIG. Accordingly, the dispensing tube 9 and the stopper tube 11 are stored in the mounting portion 2. On this occasion,
The dispensing cylinder 9 is tilted rearward and the stopper 11 is tilted forward to be in the prone state, and the top opening of the stopper 11 is closed at the tip opening of the dispensing cylinder 9. Further, since the rear portion of the cover plate 10 is fitted into the window hole 8 and the front end portion is placed on the upper surface of the top wall 5 in front of the bulging portion 6, it projects upward from the upper surface of the neck of the container body. Is about twice the wall thickness and can be stored in a compact state.

Further, if the lid plate 10 is pulled up from this state, the reversing wall 12 is elastically inverted upward and the dispensing cylinder 9 returns to the original state in which the dispensing tube 9 is erected.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 4 show an embodiment of the present invention. In the drawings, reference numeral 1 denotes a pouring cap. The cap 1 is integrally formed of a synthetic resin, and includes a mounting portion 2 and a pouring portion 3.

The mounting portion 2 has a top wall 5 extending from an upper end edge of a cylindrical peripheral wall 4 to be fitted to the mouth and neck portion a of the container body A, and a circular portion having a projection width approximately equal to the thickness at the center of the top wall 5. Bulge 6
Is protruding. In addition, a sealing cylinder 7 is provided to be fitted in a liquid-tight manner from the back surface of the top wall 5 to the inner periphery of the neck of the container body. Further, a window hole 8 is formed in the center of the top wall 5. This window 8
Is formed on the bulging portion 6 and has an arc-shaped front side located at the center of the front portion of the bulging portion 6 and has an irregularly shaped rectangular shape having straight side sides and a rear side.

The pouring section 3 projects upwardly from the top wall 5 of the mounting section, and communicates with the mounting section 2 through the window hole 8. The lower end is located at the center of the leading edge of the window hole 8. A cylindrical pouring cylinder 9 which is rotatably connected to a front portion thereof and rises upward, and a rectangle which is rotatably connected to a lower edge of a rear side running to the left and right of the window hole 8 and is rotatably connected to the upper portion. A plate-shaped cover plate 10, a rectangular tube-shaped stopper tube 11 protruding from the lower center of the front surface of the cover plate 10 and having an open lower end surface, and an inclined surface having a lower surface descending rearward; And a reversing wall 12 having the lower edge of the stopper tube 11 as a peripheral edge, closing the window hole, projecting the upper part of the pouring cylinder 9, and the mounting portion top wall 5 is provided so as to be elastically reversible up and down. ing.

The reversing wall 12 includes a central strip-shaped wall 12a, a pair of left and right front side walls 12b, 12b, and a pair of right and left rear side walls 12a.
c and 12c, the periphery of each wall is connected to bendable, and the wall is formed thin so as to be easily inverted. The strip-shaped wall 12a extends forward from the lower edge of the front wall of the stopper 11 and then slopes downward to connect the tip to the center of the front edge of the window hole 8 and to project the upper part of the pouring cylinder 9 to the inclined portion. I have. The front side wall portions 12b, 12b are formed on the side edge of the strip-shaped wall 12a, one side from the rear end corner of the strip-shaped wall to the lower end corner of the cover plate 10, and the front end corner of the front strip-shaped wall 12a from the lower end corner of the cover plate 10. Each of the rear side walls 12c, 12c has a triangular plate shape having two sides on the rear side of the front side wall 12b and the lower side of the stopper tube 11 side wall with the periphery of the window hole 8 leading to the periphery. No.

[0013]

[Effect of the Invention] As described above, the cap of the present invention has the above-described structure, so that the dispensing cylinder can be opened and closed by a simple one-touch operation of pushing down and pushing up the lid plate, and the dispensing cylinder is opened when the lid is opened. When the lid is closed, the spout cylinder and the stopper cylinder are housed in the mounting part, and the lid plate is fitted in the window hole of the bulging part, so that the upward protruding width is extremely small. It has various effects, such as taking up no space during transportation and storage, and since there is no fear of liquid leakage since the opening of the tip of the dispensing cylinder is closed by the top surface of the stopper.
