Description

[Detailed description of the invention] The present invention relates to a dispensing cap consisting of a synthetic resin stopper and a lid.The lid can be easily attached to and removed from the stopper, and the lid can provide a relatively tight seal. The purpose is to be able to hold it firmly.

There are various types of dispensing caps that are made up of a combination of a stopper and a lid, but most of them have the stopper tightly fitted and assembled into the opening of the bottle, which is a liquid container, and the lid is attached to the bottle. It was designed to be screwed into the mouth.

For this reason, each time an attempt is made to pour out the liquid content from the bottle, the lid must be rotated at least once to remove it from the bottle, making the operation of attaching and detaching the lid cumbersome. In addition, there are devices that use an undercut to assemble the lid to the stopper, but this requires a relatively large amount of force to attach and remove the lid, which reduces the ability of the lid to maintain a tight seal. There was a need to weaken it.

The present invention has been devised to eliminate the drawbacks of the above-mentioned conventional examples, and one embodiment of the present invention will be described below with reference to the drawings.

The dispensing cap according to the present invention includes a stopper 1 that is tightly assembled to the mouth of a bottle 22 to form a spout for the liquid inside, and a lid 15 that opens and closes the spout formed by the stopper 1. It is composed of.

The plug body 1 has a regular polygonal truncated cone shape, and extends from the upper end of the fitting tube 2 which is tightly fitted and assembled into the mouth of the bottle body 22 to the lower end of each inclined surface 7 which is the outer surface. A removable tube 6 is provided with an engaging groove 8 having a length that does not reach both ends of the surface, and a bottom plate 11 is connected from the upper end of the removable tube 6 to the lower end, and the upper end is spread out in a flat shape. The pouring tubes 9 are arranged in a row, and the central part of the bottom plate 11 is divided by a thin broken part 13 to form a cut piece 12.
A knob 14 is integrally provided upright from the circumferential edge of the upper surface of the cut piece 12.

In the case of the illustrated embodiment, the fitting cylinder 2 (see especially FIG. 1) is composed of an outer cylinder piece 3 and an inner cylinder piece 4, and there is a space between the outer cylinder piece 3 and the inner cylinder piece 4. The upper end of the opening of the bottle body 22 is tightly fitted.

A locking strip 5 that engages with a circumferential groove formed on the outer circumferential surface of the opening of the bottle body 22 is provided around the lower end of the inner circumferential surface of the outer cylinder piece 3. The fitting assembly of the stopper 1 to the bottle body 22 is strengthened by the engagement with the bottle body 22, and the sealing strip provided around the outer circumferential surface of the inner cylinder piece 4 makes the assembly of the stopper 1 to the bottle body 22 firm. This makes the attachment tighter.

The removable tube 6 erected from the upper end of the fitting tube 2 has a regular polygonal truncated cone shape, and the number of angles thereof is twice the number of angles of the assembled tube 17 in the lid body 15, which will be described later. .

The engagement groove 8 formed at the lower end of each inclined surface 7 forming the outer surface of the detachable cylinder 6 is horizontally elongated as shown in FIG. Rather, it is not formed at the connecting portions of the respective inclined surfaces 7, that is, at the ridge line portions.

In the illustrated embodiment, the pouring tube 9 connected to the upper end of the removable tube 6 is connected at approximately the mid-height position of the tube wall, as if it were a completely independent part from the detachable tube 6. However, in some cases, it may be configured to stand directly from the inner circumferential end of the upper end surface of the detachable tube 6.

That is, the inner circumferential surface of the inner tube piece 4 of the fitting tube 2, the inner circumferential surface of the detachable tube 6, and the inner circumferential surface of the pouring tube 9 form a continuous smooth surface, so it is constructed in this way. This allows the content liquid to be poured out more smoothly.

As in the illustrated embodiment, a liquid cutting edge 10 may be provided around the upper end of the upper end of the dispensing tube 9, which expands upward in the shape of a flap.

When forming this liquid cut edge 10, the upper end surface of the spouting tube 9 is made a flat surface with a certain width, and the liquid cut edge 10 shown in the figure is placed on the outer circumferential edge of this flat upper end surface. Set up

In this case, a step is formed between the upper end surface of the dispensing tube 9 and the liquid cutting edge 10, and when dispensing the content liquid is completed and the bottle body 22 is raised to drain the liquid, this step is formed. The content liquid located on the liquid edge 10 can be sucked by its surface tension, and dripping of the content liquid can be reliably prevented.

A cutout piece 12 is formed at the center of the bottom plate 11 connected to the lower end of the spouting tube 9 and divided by a broken part 13.
Since the spout is formed by cutting out the cut piece 12 from the bottom plate 11, at least one part of the circumferential edge of the cut piece 12 is located near the circumferential edge of the bottom plate 11. It is desirable to allow the content liquid to flow out to the end from the opened spout.

A knob 14 erected on the cut piece 12 applies a lifting force to the cut piece 12 via the knob 14, and uses this pulling force to break the breakage portion 13 and cut out the cut piece 12. Therefore, it is desirable to have a shape that allows the user's fingertips to easily apply a pulling force.

For example, in the illustrated embodiment (see especially FIG. 2)
The knob piece 14 has a loop shape, and by inserting the tip of a finger into the loop and hooking it, a pulling force can be applied as it is. .

The lid body 15 includes a tight-fitting tube 20 that fits tightly into the spouting tube 9 described above from the bottom surface of the top plate 16, and an engagement piece 19 that engages with the engagement groove 8 formed in the detachable tube 6 described above. The assembly tube 17 has an assembled tube 17, and an outer tube wall 21 that covers the stopper 1 is suspended.

The assembly cylinder 17 has a regular polygonal (square in the illustrated embodiment) cylinder shape with half the number of angles of the above-mentioned detachable cylinder 6, and a lower end of the inner surface of each wall plate 18 is provided with the engagement groove 8. An engaging piece 19 that engages is provided.

The engagement between the engagement groove 8 and the engagement piece 19 is as follows:
5 to keep the stopper 1 sealed, therefore, an engagement groove 8 may be formed on the cover 15 side and an engagement piece 19 may be formed on the stopper 1 side.

Further, as is clear from the operation description to be described later, the engagement between the engaged groove 8 and the engagement piece 19 is released by rotating the lid body 15 with respect to the stopper body 1. The lid 15 can be detached from the stopper 1 by turning the lid 15. At this time, the engaging piece 19 is easily removed from the engaging groove 8 as the lid 15 rotates. It is desirable that the side ends of the fitting groove 8 and the engaging piece 19 be rounded to form inclined surfaces.

The outer cylindrical wall 21 does not have a special effect on the assembly of the lid 15 to the plug 1, but simply allows the lid 15 to protect the entire plug 1 when the lid 15 is assembled to the plug 1. is covered to give the overall appearance of the container a simple and pleasing appearance.

However, if the outer cylinder piece 3 of the fitting cylinder 2 is formed so as to protrude greatly outward, and the outer cylinder wall 21 is fitted almost tightly into the outer cylinder piece 3 that protrudes outward. Since dust and the like are prevented from entering the lid body 15 that closes the plug body 1, sanitary use can be achieved.

Since the present invention is structured as described above,
The stopper 1 can be securely assembled to the bottle 22 by simply pressing together.

To open the stopper 1, pull up the knob 14 with your fingertips to apply a lifting force to the cutout piece 12, and this pulling force breaks the breakage part 13, cuts the cutout piece 12 from the bottom plate 11, and opens the spout. Open.

Once the spout is opened, the entire bottle 22 may be tilted to pour out the liquid content.

Furthermore, the lid 15 can be assembled to the plug 1 by simply fitting the lid 15 onto the plug 1 from above and pressing it.

That is, when the lid body 15 is fitted onto the stopper body 1 from above, the tightly fitting cylinder 20 enters into the spouting cylinder 9 and at the same time, the assembly cylinder 17 is fitted into the detachable cylinder 6. At this time, since the assembly tube 17 and the detachable tube 6 are regular polygons, and each inclined surface 7 of the attachment and detachment tube 6 is an inclined surface whose upper end is inclined inward, the assembly tube 17 naturally Each wall plate 18 of the removable cylinder 6
The lid body 15 is rotationally displaced so as to face each of the inclined surfaces 7 .

When a pressing force is further applied to the lid 15 from this state, the wall plate 18 is elastically deformed due to the force of pushing outward due to the slope of the inclined surface 7, and the engaging piece 19 is inserted into the engaging groove 8. The lid body 15 is engaged with the stopper body 1 to maintain its assembly.

At this time, as is clear from FIG.
At the end of the assembly of the lid 15 to the stopper 1 when the lid 15 is engaged with the engagement groove 8, the upper end of the spout tube 9 comes into close contact with the lower surface of the top plate 16 and serves to keep the bottle 22 sealed.

On the other hand, the lid 15 is removed from the stopper 1 and the bottle 2 is removed.
In order to open the lid 15, it is sufficient to simply apply rotational force to the lid 15.

That is, when a rotational force is applied to the lid body 15,
Since the ridge line portion on the outer surface of the detachable tube 6 pushes the wall plate 18 outward, this force causes the wall plate 18 to elastically deform outward and rotate to engage the engagement piece 19. Remove from groove 8.

When the engagement piece 19 is disengaged from the engagement groove 8, the engagement piece 19, that is, the wall plate 18 is attached to the detachable tube 6.
The cover body 15 is elastically deformed by being pushed outward on the ridge line of the outer surface of the wall plate 18, and due to the elasticity of the wall plate 18 and the slope of the ridge line of the detachable tube 6, the lid body 15 has an upward force. A pushing force is applied to the cap body 15, and this pushing force causes the lid body 15 to separate upward from the stopper body 1. In this way, the lid 15 can be naturally removed from the plug 1 by simply rotating it by a desired amount with respect to the plug 1.

The amount of rotation relative to the lid 15 when the lid 15 is removed from the stopper 1 is at most 2π/16, that is, 25.5 [°] in the illustrated embodiment.

Further, since the removable cylinder 6 has a shape whose diameter becomes smaller toward the upper position due to the slope of each inclined surface 7, the lid body 1
5 to the removable cylinder 6, simply press the lid 15 onto the removable cylinder 6 from above, and each wall plate 18 of the lid 15 is guided by each inclined surface 7, so that it can be assembled smoothly and reliably. will be achieved.

As is clear from the above description, the dispensing cap according to the present invention is extremely easy to handle, as the lid 15 can be reliably attached to and removed from the stopper 1 with just pressing and slight rotation. In addition, since the lid body 15 securely holds the seal and its holding force is strong, there is no risk of the seal deteriorating.Furthermore, both the plug body 1 and the lid body 15 have a simple structure, making it easy to manufacture. It has action and effect.
