Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to polyethylene terephthalate (P) used when sold by injecting drinking water.
ET) for a bottle of drinking water.

[0002]

2. Description of the Related Art A transparent bottle made of polyethylene terephthalate (PET) is suitable for sale by putting drinking water in a plastic bottle, and a product bottled with such drinking water is widely distributed in the market. It is also one of the popular products. However, consumers have been complaining that foreign substances such as mold and resin shavings are mixed in this kind of drinking water packed in transparent bottles that are distributed in the market these days, which is also a social problem. There is.

[0003]

This is because the conventional transparent bottle made of polyethylene terephthalate (PET) is a mere bottle having a cylindrical shape and it is not particularly easy to find a foreign substance. This is because there was a high possibility that even if there was a foreign substance, it would be overlooked.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to make a side surface of a bottle have a lens function to easily remove foreign substances mixed in drinking water. It is to provide a bottle for drinking water that is easy to find.

[0005]

In order to achieve the above object, the technical means of the present invention is to provide a lens portion on the side surface of a bottle body made of polyethylene terephthalate so that the contents can be enlarged and directly viewed. That is.

The lens section is constructed by attaching a lens body to the side surface of the bottle body.

Further, the lens portion is formed by forming a transparent or semi-transparent bottle body having an outer cylindrical shape into a rectangular tube shape over the entire inner surface thereof.
It may be configured by a combination of the curved outer surface and the flat inner surface.

Further, the lens portion may be formed by forming a flat surface on an arbitrary portion of the inner surface of a transparent or semi-transparent bottle body having a cylindrical outer shape, and combining the curved outer surface with the flat inner surface.

In addition, the above-mentioned lens portion, a convex portion formed in a curved surface on the outer surface of the transparent or translucent bottle body,
It may be configured by a flat surface formed on the inner surface of the bottle body corresponding to the convex portion.

The lens portion may be constructed by providing a plurality of concentric ring zones on the outer surface of the transparent or semi-transparent bottle body.

[0011]

With the above technical means, when the lens portion enlarges the inside of the bottle and foreign matter is mixed in the drinking water, the foreign matter is enlarged and can be seen directly from the outside.

[0012]

An embodiment of the present invention will be described below with reference to the drawings. The bottle for drinking water of the present invention is used by being filled with drinking water such as mineral water. Instead of the drinking water, carbonated drinking water, fruit drinks, tea drinks (oolong tea, Japanese tea, black tea, etc.) It goes without saying that it also covers bottles that are packed and sold with sports drinks, coffee drinks, etc.

The bottle 1 for drinking water of the present invention comprises a transparent or semi-transparent bottle body 2 made of polyethylene terephthalate (PET), and a lens portion 8 for enlarging the contents and directly looking at the side surface thereof.

The bottle body 2 has a conventionally well-known shape in this type of bottle, for example, a substantially cylindrical outer shape, and the bottle size is not limited to any one from a small capacity to a large capacity. A plurality of short cylindrical recesses 3 ... Are recessed on an arbitrary portion of the outer surface 5 of the main body 2 (see FIGS. 1 and 2).

The bottle body 2 may have a conventionally well-known shape as described above, and is not limited to the shape such as an outer shape such as an outer cylindrical shape, an outer conical shape, or a pyramid shape.

The lens portion 8 is obtained by embedding a spherical lens body (one-sided convex surface, one-sided flat surface) 9 formed in a size that can fit into the recess 3 in the recess 3 of the bottle body 2. It is configured by being integrally formed (see FIGS. 1 and 2). Therefore, the contents in the bottle body 2 can be enlarged by the lens portion 8, and the drinking water bottle 1 itself is provided with a lens function capable of being directly viewed.

The size and shape of the lens body 9 constituting the lens portion 8 are not limited, and can be appropriately changed in size together with the concave portion 3 of the bottle body 2. For example, the lens body 9
May have another lens shape such as an aspherical single lens or a biconvex lens, and when the lens shape is a biconvex lens or the like, the shape of the concave portion 3 is also adapted to the lens shape. FIG. 8 shows another example of the lens body 9.

FIG. 8 shows a Fresnel lens (Fresne lens) constructed by dividing one surface into a large number of ring zones 10.
1's lens) is used for the lens body 9, a plurality of short cylindrical concave portions 3 ... Are provided in an arbitrary position on the outer surface 5 of the bottle body 2, and the concave 3 has the Fresnel lens as the lens body. 9 is embedded and embedded. Further, as described above, the lens body 9 made of a Fresnel lens may be directly attached to the outer surface 5 without being embedded in the outer surface 5 of the bottle body 2. Further, each ring zone 10 ... Interval and ring zone 10 ...
Is arbitrary and can be changed appropriately.

By using the Fresnel lens as the lens body 9 as described above, the depth of the recessed portion provided in the bottle body 2 can be made smaller as compared with the case where a convex lens is used, and the lens body from the outer surface 5 of the bottle body 2 can be removed. Since the degree of protrusion can be suppressed, the appearance of the entire bottle is neat, and furthermore, the apexes of the respective zonal portions 10 ... Of the Fresnel lens have a non-slip action when holding the bottle and are very convenient to use. .

In the above embodiment, the lens portion 8 is constructed by embedding the lens body 9 in the concave portion 3 provided in the bottle body 2, but the lens body 9 is attached to the side surface of the bottle body 2. There is no particular limitation as long as it is provided, and the lens unit 8 may be configured by directly attaching the lens body 9 to the side surface of the bottle body 2, for example.

Next, the embodiment shown in FIG. 3 will be described.
In this embodiment, the inner surface 4 of the bottle main body 2 made of polyethylene terephthalate (PET) and having a cylindrical outer shape is formed into a rectangular tube shape so that the side surface of the bottle main body 2 serves as the lens portion 8. The bottle body 2 is not limited to the outer cylindrical shape, but may have a conical outer shape as long as it has a circular cross section.

That is, a spherical lens body (a convex surface on one side, a flat surface on one side) having a cross section as shown in the drawing is formed on the side surface of the bottle body 2 by the curved outer surface 5 and the flat inner surface 4.
The lens portions 8 are formed at four places that have similar lens functions, and the bottle body 2 itself imparts a lens function.

The inner surface 4 may be formed in a rectangular tube shape over the entire height, and the lens portions 8 extending in the height direction may be provided at four locations in the circumferential direction. If it is provided intermittently at predetermined intervals in the vertical direction, the lens portions 8 ... Are provided intermittently in the height direction of the bottle 1.

Next, the embodiment shown in FIG. 4 will be described.
In this example, polyethylene terephthalate (PET)
By forming an arbitrary portion on the inner surface of the cylindrical main body 2 having a flat outer shape into a flat inner surface 6 ..., a combination of a flat inner surface 6 and a curved outer surface 5 at a portion corresponding to the inner surface 6 is formed. As shown in the figure, a large number of lens portions 8 ... Having a lens action similar to a spherical lens body having a cross-sectional shape (convex surface on one side, flat surface on one side) are formed, and the bottle body 2 is formed.
That will give the lens function. The bottle body 2 is not limited to the outer cylindrical shape, but may have a conical outer shape as long as it has a circular cross section.

Further, in this embodiment, since the flat inner surfaces 6 are arranged side by side in the entire area of the inner surface circumferential direction, the lens portions 8 are arranged side by side in the circumferential direction of the bottle 1, but this is not restrictive. Alternatively, for example, the flat inner surface 6 may be provided only at an arbitrary position on the inner surface, and the lens portion 8 may be provided at an arbitrary position in the circumferential direction of the bottle 1, and changes within the scope of the present invention are appropriately made. Further, for example, the long flat inner surface 6 may be provided in the height direction of the bottle body 2, and the lens portion 8 may be provided in the height direction of the bottle 1.

Next, the embodiment shown in FIG. 5 will be described.
In this example, polyethylene terephthalate (PET)
The outer side surface of the bottle body 2 having a cylindrical outer shape is bulged into a curved surface (R shape) to form a convex portion 7 ... And a flat shape is formed on the inner surface of the bottle body 2 corresponding to the convex portion 7. A number of lenses that form a spherical surface lens body (a single-sided convex surface, a single-sided flat surface) like a cross-sectional shape as shown by the combination of the curved convex portion 7 and the flat inner surface 6. .. are formed, and the bottle body 2 itself imparts a lens function.
The bottle body 2 is not limited to the outer cylindrical shape, and may have the outer rectangular tube shape, or the outer conical shape or the pyramid shape, and is not limited.

Further, as for the bulging state of the convex portion 7, it is possible to bulge only a corresponding portion partially in a hemispherical shape. The protruding shape of the convex portion 7 may be any shape without any limitation. The flat inner surface 6 can also be changed according to the shape of the convex portion 7.

When the convex portion 7 is bulged into a long ridge as described above, the flat surface 6 formed on the inner surface side
Is formed to be elongated in the height direction in accordance with the convex portion 7 bulging on the elongated protrusion, and thereby the lens portion 8 is formed in the bottle height direction.

Next, the embodiment shown in FIGS. 6 and 7 will be described. In this embodiment, the outer surface 1 of the bottle body 2 made of polyethylene terephthalate (PET) has a rectangular outer shape.
2 is provided with a plurality of annular zones 11 ... Concentrically, and a lens section 8 having a so-called Fresnel lens-like configuration and operation is provided.
(See FIGS. 6 and 7). Further, the shape, spacing, etc. of each ring zone 11 are arbitrary and can be changed appropriately.

Therefore, by forming the lens portion 8 having a Fresnel lens-like structure directly on the outer surface 12 of the bottle body 2 as described above, the foreign matter mixed in the drinking water is enlarged and easily directly from the outside. Not only is a sufficient discoverable lens function imparted to the bottle 1 itself, but also the bottle body 2 can be made thin, which is low in cost. It should be noted that the bottle body 2 is not limited to the external cylindrical shape, and may have an external cylindrical shape, or may have an external conical shape, a pyramidal shape, or the like, and is not limited.

In the present embodiment, the inner surface 6 of the bottle main body 2 corresponding to the plurality of concentric annular zones 11 ... Is formed into a flat shape, and the plurality of concentric annular zones 11 ...
Although the bottle body 2 itself is provided with a lens function by the combination of the inner surface 6 and the flat inner surface 6 (see FIG. 7 in which a part of the side surface of the bottle is shown in cross section), the outer surface 12 as in the present embodiment. When the lens portion 8 having a Fresnel lens-like structure is provided in the bottle body 2, the inner surface of the bottle body 2 may be a flat surface, a convex surface, or a concave surface, and is particularly limited to the inner surface shape. Not a thing.

In the above embodiment, the ring zone 11 is provided in the height direction ⅔ of the drinking water bottle 1 so that the entire area has a lens function. The annular zone 11 ...
The lens action may be imparted to the entire drinking water bottle 1 in any direction, and the outer surface 12 of the drinking water bottle 1 may be provided with a ring portion 11 of a desired size. It may be provided as desired and is not limited in any way and is arbitrary.

Further, as shown in FIGS. 3 to 7 and described above, the shape of the bottle main body 2 itself exerts the lens action without disposing the lens body 9 separately, but it is transparent or translucent made of polyethylene terephthalate (PET). The structure of the bottle body 2 is not limited to the structure of each of the embodiments described above with reference to FIGS. 3 to 7 as long as the lens portion is provided on the side surface of the bottle body 2 so that the contents can be enlarged and directly viewed.

For example, as another conceivable example, a convex portion which is formed in a curved (hemispherical) shape is provided on the inner surface of a transparent or semi-transparent bottle body having an outer cylindrical shape, and the curved surface of the outer surface and the inner surface are A curved surface may form a lens portion that exhibits a biconvex lens-like configuration and action (not shown), or a curved surface shape (hemispherical shape) is projected on the inner surface of a transparent or semi-transparent bottle body having an outer rectangular tube shape. A convex portion to be formed may be provided to form a lens portion having a spherical lens (single-sided convex surface, single-sided flat surface) -like configuration and action by the outer flat surface and the inner curved surface (not shown). Modifications are possible within the scope of the invention.
