Abstract

PROBLEM TO BE SOLVED: To easily detach a cap from a container after the consumption of content by providing an open part having a ridge for fitting a cap not formed thereto or formed thereto extremely small to the outer periphery of a mouth part. SOLUTION: A ridge 2 is formed to the upper end of the outer periphery of the mouth part of a container 1 and a part thereof is formed into an open part 3 where the ridge 2 is omitted. The ridge 2 is fitted to the ridge 6 formed to the inner periphery of the cylindrical wall of a cap 4 to strongly attach the cap 4 to the container 1. When the cap 4 is detached from the container 1, an outer lid 11 is pulled in the direction shown by an arrow, that is, in an upward direction. Since the ridge 2 of the container 1 at the part of a hinge 2 becomes the open part 3 and does not become the fitting state with the ridge 6 of the cap 4, the cap 4 begins to easily detach from the container 1 from this part. When the outer lid 11 is further pulled upwardly, the cap 4 is perfectly detached from the container 1.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a container such as a glass bottle for accommodating various contents such as edible oil and various seasonings.

[0002]

2. Description of the Related Art In a conventional container, a ridge is provided on the entire outer periphery of a mouth portion for fitting a cap.
Also, a ridge is provided on the inner circumference of the cylinder wall of the cap,
By mechanically plugging the cap into the container mouth from above at once, the ridge formed on the outer periphery of the container mouth and the ridge of the cap are firmly fitted.

[0003]

The above-mentioned conventional container is
After filling the contents, it is quickly plugged from above with a strong mechanical force, and the container and the cap fit tightly,
It is extremely difficult to remove the cap from the container manually. The present invention has been made to enable the cap to be easily removed from the container after consuming the contents, and to separate and collect the container and the cap to recycle the container and realize effective use of resources. It is.

DISCLOSURE OF THE INVENTION The present invention relates to a container having a ridge for fitting a cap on the outer periphery of a mouth, in which the ridge is not formed or is formed extremely small. A container having a portion. In the opening portion of the bottle ridge, the ridge is not formed or is formed extremely small, so that the cap and the container are not fitted in this portion. Therefore, if you push or pull the cap upward with this open part,
When the cap begins to come off, it can finally be removed from the container.

If the cap is provided with a pulling means and the pulling means is located near the opening, the cap can be easily removed by pulling the pulling means of the cap. When the cap is a so-called hinge cap in which the outer lid is hingedly attached to the cylinder wall, it is not necessary to provide a special pulling means by using the outer lid as the pulling means. In this case, the hinge part of the cap is provided near the open part of the container.
Most preferably, the center of the binge portion and the center of the open portion coincide.

If a vertical groove is formed on the outer peripheral surface of the container mouth and the open portion is located above the vertical groove, a rod-shaped device such as a spoon handle is inserted in the gap between the vertical groove and the cylindrical wall of the cap. The cap can be easily removed by the lever principle by inserting and inserting. Also in this case, the action of the opening portion makes the removal easier. Further, in the case of a cap in which the cylindrical wall is formed in the shape of a hook, the cap can be removed by cutting the cylindrical wall with a cutter along the vertical groove. In this case, since the upper part of the vertical groove is an open part and no ridge is formed or it is formed extremely small, it is possible to cut to the top plate part of the uppermost part of the cylinder wall, The cap can be easily removed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings showing embodiments. 1 is a cross-sectional view of the container 1 of the embodiment with a cap 4 attached, FIG. 2 is a top view of the container 1, and FIG. 3 is a cap 20 of the container 20 of the embodiment.
FIG. 4 is a cross-sectional view of a state where the container 20 is mounted, FIG. 4 is a top view of the container 20, and FIG.

The container 1 is a glass bottle, and as shown in FIGS. 1 and 2, a ridge 2 is formed on the upper end of the outer periphery of the mouth, but one part is an open part 3 where the ridge is missing. ing. As shown in FIG. 1, the ridge is fitted with a ridge 6 formed on the inner periphery of the cylindrical wall 5 of the cap 4, and the cap 4 is firmly attached to the container 1. The cap 4 is a so-called hinge cap made of plastic.
2 is attached by integral molding. On the inner periphery of the cylindrical wall 5, there is provided a ridge 6 that fits with a ridge 12 formed on the outer periphery of the mouth of the container 1. At the top of the tube wall 5 is an outlet
However, a pull ring 8 is formed therein, and by pulling the pull ring 8, the annular cut portion 9 is cut and opened. In addition, reference numeral 10 denotes a seal tube portion, which is in close contact with the inner periphery of the mouth portion of the container and seals the contents. Further, the hinge 12 of the cap is provided at a position where the center line thereof coincides with the center line of the opening 3 of the container.

When removing the cap 4 from the container 1,
The outer lid 11 is pulled in the direction of the arrow, that is, upward. The projecting ridge 2 of the container at the hinge portion is an open portion 3 as shown on the left side of FIG. 1 and is not in a fitted state with the projecting ridge 6 of the cap. First, when the outer lid is further pulled upward, the cap is completely dropped from the container.

In the above embodiment, the outer lid 11 also serves as the pulling means, which is very suitable. However, if the outer lid 11 is not a hinge cap, the pulling means such as an annular knob may be additionally provided. The pulling means can be pulled upward and the cap can be easily removed. The position of the pulling means should not interfere with the removal of the cap,
It is not necessary to completely match the position of the opening portion, but if the position is completely matched as in the embodiment, the work of removing the cap becomes easier. The length of the open portion is appropriately designed so that the cap can be easily removed and the cap does not easily fall off during use of the container.

The container 20 shown in FIGS. 3 to 5 is also a glass bottle, and one vertical groove 23 is formed on the outer peripheral surface of the mouth thereof, and the open portion 22 is located above the vertical groove 23. Open part 2
In FIG. 2, the protrusion 21 at the upper end of the outer periphery of the mouth is completely cut off and flush with the vertical groove 23. The cap 24 has the same configuration as the cap 4 except that it is not a hinge cap. Although the outer lid of the cap 24 is not shown, it is a separate body.

In the case of this embodiment, since the pulling means is not formed on the cap 24, when the cap is to be removed, a rod-like shape like a spoon handle is provided in the gap 29 between the vertical groove 23 and the cylindrical wall 25 of the cap. The cap can be easily removed by the lever principle by inserting the device and using Kozil. Also in this case, the action of the opening portion makes the removal easier. Further, in the case of a cap in which the cylindrical wall is formed in the shape of a hook, the cap can be removed by cutting the cylindrical wall with a cutter along the vertical groove.
In this case, since the upper part of the vertical groove is an open part and no ridge is formed or is formed extremely small, it is possible to cut up to the top plate part 27 at the uppermost part of the cylinder wall. , The cap can be easily removed. As shown in FIG. 3, in the cap 24 of this embodiment, the protrusion 26 formed on the inner periphery of the cylindrical wall 25 is a missing portion 28 at a portion corresponding to the vertical groove 23 of the container. However, this can be easily done when cutting the cylindrical wall of this part with a cutter.

[0013]

Since the cap of the present invention can be easily removed from a container such as a bottle after use, it is possible to separately treat the cap and the container after use, and to recycle the bottle or recycle the plastic material. Realize utilization and contribute to effective use of resources.
