Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention mainly relates to a packaging container for containing a liquid or a granular material.

(Prior Art) Conventionally, as a packaging container for containing a liquid or a granular material, as described in Japanese Utility Model Publication No. Sho 49-112578, a container having spouts in two directions, No. Utility Model Sho 49-74977. As described in Japanese Utility Model Publication No. 52-123060, a container provided with a spout in the direction of inclination, as described in Japanese Utility Model Publication Nos. 57-126371 and 61-123040,
A container having a spout directly above is known. Since these containers have their spouts fixed to the container body, they must be gripped so that the spouts face downward when used. Further, depending on the remaining amount of the contents, the container must be tilted further before use.

On the other hand, in Japanese Utility Model Publication No. 54-25255, a container body having an inclined neck and neck and a stopper rotatably provided to the mouth and neck, and the tip side of the stopper is By bending
A "rotating type container with a stopper" is described in which the tip of the stopper can be changed sideways and upward with respect to the container body. In such a container, the “plug” can be tilted at an appropriate angle with respect to the main body according to the remaining amount of the contents, so when applying liquid etc. compared to the conventional structure with a fixed spout Has the advantage of being easy to hold.

In addition, Japanese Utility Model Publication No. 47-40614 includes a receiver screwed to the mouth portion of shoe cream and a sponge body attached to the upper portion of the receiver. "Applicator" that is composed of one piece, and by rotatably connecting them with an inclined joint surface of about 20 to 30 degrees, the sponge body can be bent by 20 to 30 degrees by rotating the upper piece by 180 degrees. Is listed. Even in such an applicator, since the sponge body can be tilted at an appropriate angle, it is easy to hold when applying the shoe cream, and since it can be made into a linear shape, it is easy to wrap. There are advantages.

(Problems to be Solved by the Invention) By the way, in the above-mentioned "container with a rotary type stopper", the neck of the container body is inclined and the stopper is always bent outward, and
The tip of the mouthpiece has a curved shape, and even if the mouthpiece is directed upward, there is a gap between the axis of the body of the container and the axis of the tip of the mouth, so the body of the container is temporarily Even if the diameter of is reduced, it does not become a compact form.

Further, since the above "applicator" has a structure in which the upper piece of the receiver is rotated 180 ° and the sponge body is inclined only at a certain angle, the inclination angle of the spout is not changed appropriately depending on the remaining amount. It is difficult to apply it immediately to containers such as liquids.
If the structure of the above receiving device is used for a container such as a liquid, the rotating portion corresponding to the upper piece is between 0 and 180 °, and the upper piece at each position between 180 and 360 °. A step is generated in the joint portion of the lower piece, which is not preferable in terms of design.

The present invention has been made in view of the above circumstances,
The purpose is that the angle of inclination of the spout can be set appropriately, the contents can be taken out in an easy-to-hold state, and a compact external shape can be obtained during storage and transportation, and It is to provide a packaging container excellent in design.

Has a specific shape.

That is, at the upper end of the body (1) on the virtual plane (S), the long axis of the body, which is a true ellipse, is orthogonal to the axis (Y), and the short axis of the body is the axis ( By tilting Y) at a predetermined angle within the above range, as shown in FIG. 5, the outer shape viewed from the direction perpendicular to the upper end forms a perfect circle. Further, the lower end portion of the neck portion (2) on the virtual plane (S), as in the case of the upper end portion of the body portion (1), has an outer shape viewed from a direction perpendicular to the lower end portion as shown in FIG. The shape forms a perfect circle.

The upper end of the body (1) and the lower end of the neck (2) are connected to each other by a receiving portion (11) shown in FIGS. 1 and 4 and a hooking portion shown in FIGS. 1 and 6. (21) and. The receiving part (11) is a step part as a wedge which is formed along the outer peripheral edge of the upper end part of the body part (1) and whose cross section is convex toward the outer peripheral side. The hooking portion (21) is a collar which is formed in a state in which the inner peripheral edge of the lower end portion of the opened neck portion (2) is slightly overhanged inward and which is fitted to the outer circumference of the receiving portion (11). . With such a coupling structure, the neck portion (2) rotates 360 degrees with respect to the body portion (1) on the virtual plane (S).
