Description

    The present invention relates to a liquid dispensing cap suitable for discharging content liquids such as kitchen detergents, shampoos and cosmetics.

A cap body in which a fitting cylinder is erected on the top wall of a cylindrical portion that is screwed to the mouth and neck of the container body, and a valve rod is provided concentrically in the fitting cylinder with a liquid outflow path, and a cap body, An inner cylinder and an outer cylinder that are fitted to the fitting cylinder are erected, and a liquid lid cap is configured by fitting a movable lid body provided with an opening that can be fitted with the valve rod at the center. A liquid dispensing cap in which the fitting cylinder of the cap body is sandwiched between the inner cylinder and the outer cylinder of the movable lid and the seal portion and the stopper are shared is conventionally known (see, for example, Patent Document 1). .
JP 2000-16451 A

  However, in the liquid dispensing cap described in Patent Document 1, since the fitting cylinder of the cap body is sandwiched between the inner cylinder and the outer cylinder of the movable lid and the seal portion and the stopper are shared, due to variations in molding and the like. There is a problem that the operation of pulling up and pushing down the movable lid may become hard, and when used in a kitchen or the like, there is a problem that the opening is left open and the liquid contents are caused to flow out by overturning.

  Moreover, there was a problem that the liquid may drip at the time of pouring, and the finger etc. will slip when used next time, making it difficult to open the lid.

  An object of the present invention is to solve the above-described problem, and the fitting cylinder of the cap body is separated from the sealing part and the stopper by the inner and outer double cylinder walls sandwiched between the inner cylinder and the outer cylinder of the upper lid, An object of the present invention is to provide a liquid pouring cap that can be smoothly moved up and down, locked so that the upper lid cannot be easily opened during distribution, and can be easily opened during use.

In order to solve the above problems, the present invention is a liquid dispensing cap comprising a cap mounted on the mouth of a container and an upper lid mounted on the cap, as the liquid dispensing cap, The top wall is provided with a fitting cylinder provided with a stopper protrusion on the outer periphery of the upper end and a seal cylinder on the inner side, and a valve rod is provided via a support rod in the center. The top cover has a top and an outer peripheral wall, and an opening for fitting the valve rod is formed in the center of the top, and the upper cover is slidably contacted with the inner periphery of the seal cylinder when the top cover is pulled up. An inner cylinder with a bulging ridge projecting on the outer periphery of the lower end is suspended , and the outer peripheral wall is slidably contacted with the stopper ridge of the fitting cylinder , The structure characterized by providing the stopper which slides in contact with the outer periphery of a fitting pipe | tube is provided in a peripheral lower end.

In order to facilitate the pulling-up operation, in addition to the above configuration , a locking protrusion is provided on the outer periphery of the upper end of the peripheral wall of the cap. A configuration is adopted in which a push button provided with a lock piece is provided on the inner side of the lower end so that the lock piece is locked to the locking protrusion .

A fitting cylinder and a seal cylinder are installed upright on the top wall of the cap so that the inner cylinder provided on the upper lid and the outer peripheral wall are in sliding contact with each other, so that the upper lid can be lifted and pushed down smoothly. It was.
Further, since a push button is provided on the outer peripheral wall of the upper lid and the upper cover can be pulled up by pushing the pressing portion, the hands are not slipped or soiled by the content liquid adhering to the outer peripheral wall.

  Next, examples of the liquid dispensing cap of the present invention will be described with reference to the drawings.

  In FIG. 1, A is a container, B is a cap, and C is an upper lid.

  The container A includes a mouth portion 1, and the mouth portion 1 is provided with a screw 2 into which a cap is screwed.

As shown in FIGS. 1 and 2, the cap B includes a peripheral wall composed of an upper peripheral wall 3 and a screwed tube 4, and a top wall 5. A screw 6 that is screwed to the screw 2 is screwed, and a locking protrusion 7 is provided on the outer periphery of the upper end of the upper peripheral wall 3.
On the outer side of the top wall 5, a fitting cylinder 9 having a stopper protrusion 8 provided on the outer periphery of the upper end portion is erected, and on the inner side, a sealing cylinder 10 having the same height as the fitting cylinder 9 is erected. .
A valve rod 12 is installed in the center of the top wall 5 via a support rod 11.

As shown in FIGS. 1 and 3, the upper lid C includes a dome-shaped top portion 13 and an outer peripheral wall 14, and an opening portion 15 into which the valve stem 12 is fitted is formed at the center of the top portion 13. , the inner cylinder 17 projecting from the bulging protrusions 16 at the lower end of the sliding contact within the seal cylinder 10 in the circumferential is vertically.
A stopper 18 that is in sliding contact with the outer periphery of the fitting tube 9 is provided at the lower end of the inner periphery of the outer peripheral wall 14, and a pair of connecting rods 19 project from the lower end of the outer periphery, and a push button 20 is provided continuously.
The upper end of the push button 20 is a pressing portion 21, and a lock piece 22 that is locked to the locking protrusion 7 of the cap B is projected from the lower end inside.

Next, usage modes and operational effects of the liquid dispensing cap of the present invention will be described.
When the content liquid is poured out, when the cap B and the upper lid C of FIG. 1 are closed and the pressing portion 21 of the push button 20 is gripped and pressed by a finger, the lock piece 22 engages with the upper peripheral wall 3. The ridge 7 can be overcome and the upper lid C can be lifted upward. As shown in FIG. 4, the valve stem 12 can be separated from the opening 15 and the opening 15 can be opened.

At that time, the stopper 18 provided on the inner periphery of the lower end of the outer peripheral wall 14 of the upper lid C is in sliding contact with the outer periphery of the fitting cylinder 9 until it comes into contact with the stopper protrusion 8 provided on the outer periphery of the upper end portion of the fitting cylinder 9 of the cap B. At the same time , as shown in FIG. 4, the bulging ridge 16 of the inner cylinder 17 is brought into sliding contact with the inner periphery of the seal cylinder 10 so that the upper cover C can be easily lifted. Since the two cylinders of the fitting cylinder 9 are used to fit the upper lid C, the fitting can be set loosely and at the same time the liquid tightness can be improved.
In addition, variations in dimensions during molding can be absorbed.

Further, since the push button 20 is provided on the outer peripheral wall 14 of the upper cover C and the upper cover C can be pulled up via the push button 20, the outer peripheral wall can be used even if the liquid drops from the opening 15 when used before. The content liquid adhering to 14 is not touched.
Therefore, it was possible to prevent the finger from slipping or soiling due to the attached content liquid.

In the above embodiment, the container 2 is provided with the screw 2 at the mouth portion 1 and the threaded tube 4 of the cap B is threaded. However, instead of the screw, the engagement protrusion is provided, and the threaded tube 4 is replaced. You may make it fit the engagement cylinder which provided the engagement protrusion.

In the present invention, the cap body and the sealing cylinder are formed separately by the inner and outer double cylinder walls, and the sealing portion and the stopper are formed separately, so that the upper lid can be lifted and pushed down smoothly. became.
Therefore, it can be widely used as a liquid dispensing container containing various contents such as detergents and cosmetics.
