Description

[Detailed Description of the Invention] The present invention relates to a packaging bottle convenient for storing and taking out highly viscous liquid foods such as miso, jam, mayonnaise, and ketchup.

Traditionally, miso is often sold in plastic bags. However, once the plastic bag is opened, the remaining miso must be transferred to a separate container and stored in a sealed container. This is quite a hassle in ordinary households, and suitable sealed containers are not always available.

On the other hand, mayonnaise, ketchup, etc. are generally stored in plastic bottles, squeezed out through the narrow spout, and then stored in caps.
However, although they are the same seasoning, miso, which is an ancient Japanese seasoning, is not packaged like mayonnaise or ketchup, and as a result, the product image seems to be inferior to mayonnaise and the like.

On the other hand, to remove the contents from the bottle, turn the bottle downwards, but if the content is a sticky liquid such as mayonnaise, if there is little remaining, it will take time for the bottle to reach from the bottom to the mouth. Since it flows down little by little while adhering to the inner wall, it takes a very long time and it is extremely difficult to completely remove the contents. Therefore, although it is uneconomical, in reality, a considerable amount of the contents is often thrown away.

This invention was devised in view of these circumstances, and allows for the quick squeezing of highly viscous liquid foods into small or large portions. The purpose of the present invention is to provide a packaging bottle that can be washed out.

That is, the packaging bottle of the present invention includes a bottle body having a narrow mouth at the top and a wide mouth at the bottom, a cap that fits into the narrow mouth, and a cap that fits into the wide mouth and supports the bottle body in an upright position. It consists of a cap of various shapes, and is characterized by the upper half of the bottle body bulging out to a large capacity.

Hereinafter, the present invention will be explained based on the drawings.

Figures 1 to 6 show an embodiment of the present invention, in which Figure 1 is a perspective view of its appearance, Figure 2 is a front view, Figure 3 is a side view, and Figure 4 is its second view. A-A of
5 is a sectional view taken along the line B--B in FIG. 3, and FIG. 6 is an exploded perspective view. In the figure,
1 is the bottle body containing miso 2, 3 is a narrow-mouth cap, and 4 is a wide-mouth cap.

The bottle body 1 is an elastic soft or semi-hard plastic bottle, which is formed by blow molding, for example, high-pressure polyethylene resin material, and has an upper half bulging out to a large capacity to form an inverted bottle shape. In addition, both upper and lower ends have openings that communicate with the inside of the body 5 of the bottle body 1,
The upper end side has a narrow mouth part 6, and the bottom side has a wide mouth part 7.

This narrow mouth portion 6 projects vertically upward from the center of the shoulder portion 8 of the bottle body 1, and has a male thread 9 formed on its outer peripheral surface. On the other hand, the wide mouth part 7 is located at the bottom part 10 of the bottle body 1.
It protrudes vertically downward in a continuous manner, and also has a male thread 11 formed on its outer peripheral surface.

The narrow-mouth cap 3 is a normal plastic cap, and has a female thread 12 formed on its inner peripheral surface to be screwed into the male thread 9 of the narrow-mouth portion 6.

As shown in the figure, the wide-mouth cap 4 has a trapezoidal exterior (a shape that widens at the end), but the inside is formed into a cylindrical shape. A screw 13 is formed.

This wide-mouth cap 4 is for holding the bottle body 1 filled with miso 2 in an upright position.
As long as its stability is ensured, the material, shape, size, etc. are not particularly limited and are appropriately determined in relation to the bottle body 1 and the contents. For example, in terms of materials, ceramics,
Possible materials include cast metals such as aluminum, copper, and iron, synthetic resin, rubber, etc., and the shape is the base 1 of the wide-mouth cap 4.
4 is desirably at least the diameter of the wide-mouth portion 7 or larger.

Note that an inner plug having an outlet for the contents in the center may be fitted inside the narrow opening 6 or the wide opening 7.

Further, in the bottle body 1, it is preferable that the shoulder portion 8 around the narrow mouth portion 6 and the bottom portion 10 around the wide mouth portion 7 are formed to be slightly thicker than the other body portions 5.

According to the packaging bottle according to the embodiment of the present invention configured as described above, there is a narrow mouth part at the top of the bottle body and a wide mouth part at the bottom, so that consumers can control the amount of contents to be taken out or what remains. A narrow or wide mouth can be used as appropriate depending on the amount or the purpose of recycling the bottle.

That is, if you want to squeeze out a relatively small amount, remove the cap from the narrow opening and squeeze out. At this time, if the food is highly viscous and there is only a small amount left, shake it upside down or crush it.
The liquid food is dropped from the top downwards, but when the bottle of the present invention is turned upside down, there is a large bulging space at the bottom, so the remaining amount of the highly viscous liquid food can be dropped directly from the bottom. This is convenient because it is easy to do, and a large amount can be temporarily stored near the narrow opening, and then it can be quickly squeezed out from the narrow opening 6. This falling phenomenon is caused by viscosity
This is observed for liquid foods with a viscosity of 10 ³ μ (mPa·s) or more, and liquid foods with a viscosity lower than that flow down the inner wall of the bottle, so it takes a very long time to reach the narrow opening 6. Therefore, it can be said that the packaging bottle of the present invention is preferably used for liquid foods having a viscosity of 10 ³ μ (mPa·s) or more. If you want to take out a large amount in a short time, turn the wide mouth part 7 downward, remove the trapezoidal cap, and scrape out the contents from the wide mouth part.

In addition, it is possible to keep the bottle in an upright position and lower the contents into the wide mouth part of the bottle in advance, and then take out the contents immediately from the wide mouth part when necessary. can be taken out,
The economical use of bottled viscous fluids is highly advantageous.

Furthermore, the packaging bottle of this invention does not simply have a wide mouth portion 7 for taking out a large amount. That is, when taking out the fluid from the wide mouth part 7, the bottle body 1 is crushed by hand starting from the upper half and sequentially downward.
Since the upper half is formed to bulge to a large capacity, a large amount of air and fluid is pushed downward by squeezing, and a large amount of fluid is discharged from the wide mouth portion 7 at once.

In addition, if you want to wash out the small amount left, you can wash it with water or brush using both the narrow and wide mouth parts. The cleaned bottle of the present invention can be reused as a packaging bottle for the same food or other food.

Furthermore, since the bottle of the present invention has a very good appearance, it can be displayed in stores even if the content is miso, which greatly contributes to improving the image of the product.
