Description

[Detailed explanation of the idea] "Industrial application field" This proposal relates to a biaxially stretched bottle with a handle.

"Prior Art" Recently, biaxially stretched bottles made of saturated polyester resin have been used as bottles for beer, etc. Although the bottle is thin, it has excellent strength and gas barrier properties, does not leak solvent, and has a significantly lower calorific value when burned than other synthetic resins, so it is less likely to damage an incinerator. However, as bottles become larger and the storage capacity increases, the rigidity of the bottle body is lost. It became difficult to hold the bottle,
Furthermore, since the bottom of the bottle is bulged downward in a spherical shape to increase the biaxial stretching rate, it becomes difficult to stand the bottle upright. In order to eliminate such drawbacks, it has been considered to fit cylinders above and below the bottle and to span a handle between the cylinders.

``Problems to be solved by the invention'' From the perspective of preventing the above-mentioned pollution, it is desirable to mold the cylinder and the handle with saturated polyester resin like the bottle body, but since the resin material is expensive, it is costly. It was difficult.

In this project, a reinforcing tube with a handle made of a paper tube with low burning calories is fitted onto the outer surface of the bottle body made of saturated polyester resin to create a low-pollution bottle with a handle that is easy to use. The bottle is provided so that it can be easily protruded to the outside by a person when in use, and the handle is provided so that it does not get in the way when the bottle is being transported.

Then, a cylindrical part is fitted onto the outer surface of the body of the bottle body, and the lower end surface of the cylinder is positioned on the same plane as or below the lower end surface of the bottle body, thereby forming a ground plane 9 for raising the bottle body.
A part of the paper cylinder is provided with two first separation lines 11, 11 at a constant interval from the top to the bottom of the cylinder, and both separation lines A first refraction line 1 between each upper and lower end of the line.
2 and 12 are installed horizontally, and the cylinder wall portion surrounded by the first separation line and the first bending line is defined as the grip plate part 13,
A substantially concave-shaped upright plate part 14 is provided on at least one of the upper and lower ends of the gripping plate part on the cylindrical wall portion, and the lower base of the concave part forming the upright plate part and the left and right ends of the base. The left and right sides of the outside standing up from the center are separated by a second separation line 15 that is approximately U-shaped, the upper side of the concave shape is separated by second refraction lines 16, 16, and both the left and right sides inside the concave shape are separated by the first separation line 15. By the ends of the lines 11, 11,
The upper base of the concave shape part is formed by the first refraction line 12,
A finger hook notch 18 for raising the upright plate portion 14 was bored in the tube wall portion of the paper tube 7 in contact with a part of the second separation line 15.

"Operation" As shown in FIGS. 1 and 3, the grip plate part 13
The handle portion 10 formed by the and the upright plate portion 14 is the paper cylinder 7.
From the state where it does not protrude outward, the second separation line 15 is removed by using the cutout 18 that is made in contact with a part of the second separation line 15.
By raising the upright plate part 14 as shown in the figure and simultaneously pulling the grip plate part 13 outward, the grip plate part 13 can be held in the hand.

"Example" First, to explain the example shown in FIGS. 1 and 2, 1 is a biaxially stretched bottle body made of saturated polyester resin, and from the periphery of the bottom wall 2 which is formed to bulge downward in a spherical shape, The torso 3 is erected, and the mouth and neck are erected from the upper end of the torso via the shoulders 4. A cap 5 is screwed onto the mouth and neck. It is preferable to form a downward step 6 between the upper end of the body and the shoulder.

A cylindrical portion 8 of a paper cylinder 7 is fitted onto the outer surface of the body. The paper tube 7 is made of paper, synthetic paper, or the like, and has a calorific value equal to or lower than that of saturated polyester resin during combustion. The calorie burn of saturated polyester resin is approximately 5,500 cal/Kg, and that of paper is approximately 4,500 to 5,000 cal/Kg.
It is. The upper end of the cylindrical portion is engaged with the previously mentioned downward step 6, and the lower end of the cylindrical portion is wound inwardly so that its lower end surface 9 serves as a ground surface for raising the bottle body. The central lower surface of the bottom wall 2 of the bottle body may be positioned on the same plane as the lower end surface of the cylinder and serve as a ground plane.
It may be located above the ground plane. The cylindrical part and the body of the bottle body are joined with adhesive.

A handle portion 10 is formed in a part of the paper cylinder 7.
The handle portion is formed so as to be able to be pulled outward by a line of separation from the wall of the paper tube and a bend line provided between the line of separation. In the illustrated example, from slightly below the upper end of the cylindrical portion,
Two first separation lines 11, 11 are provided above and below the lower end of the cylinder at a constant interval, and a first refraction line 12, 12 is provided between the upper and lower ends of these two lines.
12 is installed horizontally, and the portion surrounded by the first separating lines 11, 11 and the first bending lines 12, 12 is the grip plate part 1.
It is set at 3. A substantially concave-shaped upright plate portion 14 is formed on the cylindrical wall portion of the lower end of the gripping plate, and the lower end of the gripping plate is connected to the paper cylinder wall through the upright plate portion. . A substantially U-shaped second separation line 15 is formed between the lower bottom side of the concave shape forming the upright plate portion 14 and the outer left and right sides rising from both left and right ends of the bottom side, and the upper side of the concave shape is Second refraction line 16, 16
However, both left and right sides inside the concave shape portion are formed by the ends of the first separation line, and the upper base of the concave shape portion is formed by the first refraction line 12 described above. The grip portion 10 is formed by the grip plate portion 13 and the upright plate portion 14,
A third refraction line 17 may be provided above the grip plate. Notches 20 and 18 for finger hooks for raising the handle portion are bored in the wall portion of the paper tube, in contact with a portion of the first and second separation lines 11 and 15 mentioned above, and on both of them. When provided on the grip plate side, it is easier to raise the grip plate if they are provided on the left and right sides as shown. As shown in FIG. 2, the handle 10 can be raised by hooking a finger on the side edge portion of the handle exposed by the notch and pulling up.

In the embodiment shown in FIG. 3, the upright plate part 14 is
An example is shown in which the notches 18 are formed on both the upper and lower ends of the upper and lower ends, and the notches 18 are provided on the second separation line side of the upper standing plate part. In this case, the upper side upright plate part becomes an inverted concave-shaped part. It should be noted that small through holes 19 are formed at each end of the first and second separation lines described above to prevent the ends of the separation lines from being torn.

Of the previously described notches 18, the notches 20, 20 on both sides of the grip plate may be omitted.

"Effect of the invention" The present invention has the above-mentioned structure, and since the cylindrical part 8 of the paper tube 7 is fitted onto the outer surface of the cylindrical part of the saturated polyester resin bottle body, the bottle body is biaxially stretched and has a thin wall. However, the body of the bottle is reinforced to provide sufficient rigidity for handling the bottle, and since the lower end surface of the cylindrical portion 8 is used as a ground surface, the bottom wall of the bottle body is formed into a spherical bulge. Even if the bottle gets larger, it will not be a problem for the bottle to stand up.Since the handle part 10 is formed as a part of the cylinder part, it is easy to hold even if the bottle becomes large.The paper cylinder 7 is made of only paper.
Alternatively, since paper is used together with other materials, the amount of calories burned is significantly lower than that of general synthetic resin, so even if it is disposed of and incinerated together with the saturated polyester resin bottle body, it will not damage the incinerator. Therefore, there is no toxic gas emitted during combustion, and even if some general synthetic resin material is used in some parts, the amount of toxic gas emitted is extremely small and will not cause pollution. do not have. Further, since the handle portion 10 is formed so as to be able to be raised by the separation line on the cylinder wall of the paper tube 7 and the bending line provided between the separation lines, it is extremely easy to form the handle, and the handle can be raised easily. This can be done by the consumer when using the bottle, and it can be done in the bottle distribution stage without bending the above-mentioned bending line, that is, with the back side of the grip plate 13 in contact with the body of the bottle. The handle does not get in the way at all during the distribution stage. Furthermore, in order to reinforce the extremely thin bottle body, the thickness of the paper tube 7 is increased to increase its rigidity, but the grip plate portions 13 of the paper tube 7 formed in this way are attached to both sides of the paper tube 7. When the bottle is pulled out using the provided notches 20, 20, the grip plate part 13 is difficult to bend due to its rigidity, and the inner surface of the notch is closed by the bottle wall, making it difficult to hold the grip plate part. line 1
Since the cut surfaces of 1 are in contact with each other, it is difficult for the grip plate 13 to separate from the paper cylinder due to frictional resistance, which makes it extremely difficult. However, in this proposal, a finger hook notch 18 for raising the upright plate 14 is provided. Second separation line 15
Since the cutout 18 is made in the cylinder wall of the paper cylinder 7 in contact with a part of the paper cylinder 7, the upright plate part 14 is
can be folded outward as shown in FIG. 2 by refraction at the second refraction lines 16, 16, and by this folding, the first refraction line 12 forming the upper base of the upright plate portion 14 also becomes a paper tube. The gripping plate portion 13 is moved outward from the cylinder wall of 7 and has the first bending line 12 as one end.
Both ends are separated from the cylindrical wall and pulled out to the outside, so after that, all you have to do is hold the pulled out ends and pull out the grip plate part further outward. It is extremely easy to form the section 10.
