Description

The present invention relates to a cap with a pull ring that is used by being attached to a small-diameter container such as ra oil or tabasco. It is related with the cap with a pull ring which can equip and can make the outer diameter of the whole small.

Caps with pull rings are often used in containers that contain edible oils, seasonings, and the like, and many of them are made of a plastic material that is different from the container mainly in terms of production and material costs. And this cap with a pull ring is plugged into the mouth of the container to make it liquid-tight, and maintains a liquid-tight state so as not to be easily removed.
The pull ring realizes easy opening, and the cap body is hinged with an outer lid so that it can be opened and closed, or it can be opened and closed by screwing. Such caps with pull rings were often used for containers with relatively large capacities and large container mouth diameters, but they were attached to containers with small capacities such as lar oil and tabasco and small container mouth diameters. The following are known for use.

JP 2001-58665 A Japanese Patent No. 2657229

As shown in FIG. 4, the cap with a pull ring of Patent Document 1 includes a container body a that stores contents and a cap c that engages with a spout b of the container, and the spout b formed in a non-open state. An annular thin cut groove e is formed on the top surface d of the upper and lower sides, and a region surrounded by the thin cut groove e is used as a seal lid f, and a pull ring h is integrated with the seal lid f via a column g. It is a thing. Then, when the cap c is engaged with the spout b of the container body a, the support column g is tilted so that the pull ring h is pressed against the top surface d of the spout b by the annular airtight projection i of the cap c. When the cap c is engaged and disengaged, the column g rises, and the pull ring h is put on with fingers to pull the thin-walled cut groove e to open the seal lid f.

Moreover, the cap with a pull ring of patent document 2 is what this applicant proposed, FIG.
As shown in FIG. 6, the spout forming portion is composed of an upper lid L that is attached to and detached from the cap main body k provided at the mouth of the container, and is divided on the top surface d of the cap main body k by a thin portion n that can be broken. o and the content extraction protrusion p are formed outside the spout forming portion o, and the thin portion n
Is surrounded by the content extraction protrusion p, and the end portion of the thin-walled portion n that is the fracture start portion is located in a portion that is not further surrounded, and a column g1 is formed at this end portion, and at the tip portion thereof Pull ring h1
Is provided so as to surround the projection p for content extraction. The cap body k can be opened by removing the upper lid L from the cap body k, placing a finger on the pull ring h1, and cutting the thin-walled portion n.

Since the cap with a pull ring of Patent Document 1 can make the diameter of the pull ring h larger than the seal lid f, the diameter of the pull ring h can be set to a size that can be applied by a finger without being affected by the diameter of the seal lid f. The thin cut groove e can be easily cut. However, in order to make the diameter of the pull ring h larger than the seal lid f, the column g connecting the pull ring h and the seal lid f.
If the contents cannot be formed on the top surface d around the seal lid f, and the contents are not cut easily and are likely to sag, the spout b is soiled and unsanitary and looks bad.

Moreover, since the cap with a pull ring of patent document 2 is provided so that the pull ring h1 may surround the outer side of the protrusion p for content extraction, it can be easily cut | disconnected and opened by putting a finger on the pull ring h1. It is convenient that the contents can be poured out from the protrusion p for contents pouring, and the contents can be prevented from dripping. However, this cap with pull ring
Since 1 is positioned outside the content extraction protrusion p, there is a tendency that the diameter becomes large. When the diameter of the container is restricted, the diameter may be larger than that of the container.

Therefore, the object of the present invention is to provide a pull ring that can prevent the contents from sagging, can be equipped with a pull ring that secures an inner diameter enough to hang a finger, and can reduce the overall outer diameter. To provide a cap.

The present invention has been proposed in order to achieve the above object, and is characterized by having the following configuration.
That is, according to the present invention,
A cap body made of a synthetic resin having a top surface and a skirt that extends downward from the outer peripheral edge of the top surface and is fitted to the outer periphery of the mouth of the container, a top plate that fits the cap body, and an outside of the top plate A cap comprising an outer lid having a side wall extending downward from the periphery,
The top surface of the cap body is formed with a spout forming portion partitioned by a thin portion that can be broken, and a content spouting wall having a notch portion outside the spout forming portion, and A strut having a base end is formed at the outer peripheral position of the spout forming portion on the side of the notch, and the strut is erected radially outward and obliquely upward with a pull ring formed at the upper tip.
A cap with a pull ring is provided.

Further, according to the present invention, on the inner surface of the top plate of the outer lid, there is an annular contact ring that hangs down from the inner surface of the top plate and presses against the top surface of the cap body outside the content pouring wall. A cap with a pull ring is formed.

Moreover, according to this invention, the said pull ring is provided with the said cap with a pull ring which is located above the said content extraction wall.

In addition, according to the present invention, there is provided the cap with a pull ring, wherein an inner diameter of the pull ring is substantially equal to or greater than an inner diameter of the content pouring wall.

Further, according to the present invention, a male thread is formed on the outer peripheral surface of the cylindrical portion extending upward from the outer peripheral surface of the skirt of the cap body or the outer peripheral edge of the top surface, and the female screw engaged with the male thread is formed. The cap with a pull ring is provided in which a strip is formed on the inner surface of the side wall of the outer lid.

The cap with a pull ring of the present invention is provided with a column at the outer peripheral position of the spout forming part on the notch part side of the content pouring wall, extending the column outward and obliquely upward, and attaching a pull ring to the upper end of the column. Therefore, the shape of the pull ring can be set avoiding the contents pouring wall, and the overall outer diameter is restricted only to the shape that the pull ring requires to the minimum. The contents can be poured out. Accordingly, it is possible to prevent the contents from drooping, to equip the pull ring with a shape that can be sufficiently hung with fingers, and to reduce the overall outer diameter.
Further, when the outer lid is fitted on the cap body, the annular contact ring of the outer lid comes into pressure contact with the top surface of the cap body. Therefore, the container can be sealed by fitting the outer lid to the cap body after opening.
In addition, since the pull ring is located above the content extraction wall, it is less affected by the content extraction wall in setting the shape of the pull ring. Since it can be removed without touching it, it is also hygienic.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

In the drawing, a cap 1 with a pull ring comprises a synthetic resin cap body 4 fitted to the mouth 3 of the container 2 and a synthetic resin outer lid 5 to which the cap body 4 is fitted. 4 is formed with a spout forming portion 8 defined by a thin portion 7 that can be broken, and a content spouting wall 10 having a notch 9 outside the spout forming portion 8. At the same time, a support column 11 having a base end portion 11a is formed at the outer peripheral position of the spout forming portion 8 on the notch portion 9 side, and this support column 11 is formed with a pull ring 12 at an upper end 11b and obliquely outward in the radial direction. It is erected upward.

The container 2 is not particularly limited as long as the cap body 4 of the cap with pull ring 1 can be plugged or screwed into the mouth portion 3, and may be of any type and material. In this Example 1, in particular, it is used for seasoning that is frequently dispensed, such as ra oil, tabasco, etc., and is made of a bottle type plastic or glass with a small opening diameter that can be opened and closed by the outer lid 5 relatively frequently. An example of a ceramic container is disclosed.

The cap body 4 is provided with an inner ring 20 and a skirt 21 under the top surface 6 to form a stopper part 22, and the stopper 3 is stoppered by applying the mouth 3 of the container 2 to the stopper part 22. Dense. Further, a male thread 23 is formed on the outer peripheral surface of the skirt 21, and this male thread 23
Is formed on the inner surface of the side wall 25 of the outer lid 5 so that the outer lid 5 can be screwed into and removed from the cap body 4. On the other hand, on the top surface 6 of the cap body 4, as described above, the content pouring wall 10 having the notch portion 9 is formed, and the spout forming portion partitioned by the thin portion 7 inside thereof. 8, and the base end portion 11 a of the support column 11 at the outer peripheral position of the spout forming portion 8.
Is formed. The thin-walled portion 7 may have any configuration as long as the portion where the pull ring is pulled breaks. Usually, as shown in FIG. 1, a V notch is generally inscribed from the lower inner surface. .

The column 11 is erected obliquely upward toward the outside by avoiding the content extraction wall 10 by the notch 9, and the pull ring 12 formed at the upper tip 11 b of the column 11 is the content extraction wall 10. It is possible to position it above the, and it does not hit the content extraction wall 10. as a result,
The pull ring 12 can have an inner diameter that is approximately the same as or larger than the inner diameter of the spout forming portion 8, and the mouth portion 3 of the container 2 has a smaller diameter. Also, it is possible to make the inner diameter as large as a finger can be hung. Therefore, by pulling and pulling the finger on the pull ring 12, the thin-walled portion 7 can be broken, the spout forming portion 8 can be removed and opened, and the contents of the container 2 can be poured out from the content pouring wall 10, The dripping of contents can also be prevented.

The cap body 4 is provided with a sorting and discarding function. This sorting and discarding function is for cutting out a part of the skirt 21 constituting the stopper portion 22 as shown in FIG. A fragile portion 26 is provided. Therefore, this weak part 26 is fractured | ruptured, the cap main body 4 can be easily removed from the opening | mouth part 3 of the container 2, and separation disposal can be implement | achieved easily.
