DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hollow container capable of measuring and discharging a required amount of contents contained in a container, and particularly to soy sauce and other liquid seasonings or liquid detergents. The present invention relates to a hollow container having a graduated cup-shaped lid suitable for measuring the solution.

[0002]

2. Description of the Related Art Contents stored in large quantities in large packaging containers, such as soy sauce, mirin, sugar and other seasonings, or liquid or powder contents such as bleach, soap and other detergents, Previously, when the required amount was poured out and used, the contents were divided into small containers and weighed before use.
A package separate from the packaging container is prepared, and it is inconvenient to use it in advance when using it, and it is often lost.

In order to eliminate the above inconvenience, Japanese Utility Model Publication No. 56-5572 and Japanese Utility Model Publication No. 63-353
As described in JP-A-77-77, etc., a measuring cup is placed on a closed lid of a packaging container so as to form a double lid, or as disclosed in Japanese Utility Model Publication No. 54-22525 and Japanese Utility Model Application Publication No. 60-5014.
No. 6, Japanese Utility Model Laid-Open No. 1-51043, and the like, a packaged container having a hermetically sealed lid having a graduation scale also serving as a weighing container has been widely used.

[0004] Of these containers, the former is a measuring cup 44 formed separately from a sealing lid 43 screwed to a mouth-neck portion 42 of a hollow container 41 as shown in FIG. The measuring cup of this type has a scale 45 printed on the wall surface of a cup-shaped container 44 formed by injection molding or the like as shown in FIG. Since it is shown, its structure is very simple, it can be manufactured with good productivity and at low cost, and therefore it is generally widely used in terms of economy.

[0005] As shown in FIG. 8, a lid 53 is screwed onto a mouth and neck 52 of a hollow container 51. The lid 51 is attached to a surface of an inner cylinder 53a also serving as an inner plug. Scale 5
The measuring cylinder formed by attaching 4 is closely fitted to the inner surface of the mouth-neck portion 52, and the screw of the outer tube 53b is screwed to the threaded portion of the outer surface of the mouth-neck portion 52 to form a seal. . A hollow container equipped with such a lid is convenient because the lid can be removed from the mouth and neck of the container and the internal solution can be measured as a measuring cup, but it is somewhat difficult to remove the lid. If a large force is required and the fitting between the inner cylinder and the mouth and neck is loosened so that the lid can be lightly removed with a small force, the degree of sealing may be reduced and the liquid content may leak. As shown in the figure, the body is provided with graduations for measurement on the inner cylinder surface of the double cylinder provided inside and outside, so that it is slightly difficult to see from the outside when weighing, and the lid Has a somewhat complicated structure, and the productivity is poor, so there is room for improvement.

Therefore, by improving the above-mentioned various drawbacks, the lid of the hollow container also functions as a measuring cup, and it is extremely easy to attach and detach it to the mouth and neck of the container, and to remove the contents. As a hollow container for liquids with a lid that is easy to see when weighing out and weighing, and that has a structure that prevents the attached inner solution from leaking when the lid is attached to the container after weighing, No. 61-80961 and No. 63-

In addition, the scale is easier to see when weighing than the conventional one. However, when a scale or the like is printed or engraved on the side wall surface of the lid as described above, it is necessary to accurately measure and position the position where the scale or the like is displayed each time before performing printing or the like. ,Also,
Since the dispensing adapter has a slightly complicated structure, there was a problem in terms of productivity.

For the reasons described above, the contents contained in the container can be easily measured, the scale for measurement is easy to see, and when the lid is closed after being used for measurement, It is desirable to have a hollow container lid as simple as possible so that the contents remaining in the lid do not leak, and these structures can be manufactured at low cost. . In addition, the scale marked on the above-described measuring container or the like is inscribed and indicated by an undercut or the like on the wall surface of the container at the time of molding, but when the solution is poured into the measuring container as it is, the measuring container Because the scale of is difficult to see, so that it is easy to see,
In addition, the display is performed by printing or the like.In this case, it is necessary to print the container so that the displayed position does not shift. Therefore, it is desired to have a lid that can easily set the display position and that can print reliably, and that also serves as a measuring container having a structure that is easy to see.
