Description

[Detailed Description of the Invention] The present invention relates to a plastic container with a handle, and more particularly to a plastic container provided with a handle to facilitate gripping when pouring out the liquid contained therein.

Relatively large capacity plastic containers, such as narrow-mouth or wide-mouth plastic bottles, are preferably equipped with handles to facilitate gripping, but conventional handles have often been integrally molded with the container body. Therefore, if the internal volume is sacrificed, or if it is not sacrificed, there is a problem in that the handle protrudes largely to the side and the volume for storing the container increases. Another problem was that a special and complicated mold and process were required for integral molding.

The present invention has been devised in view of the problems of the prior art described above, and the present invention is directed to a plastic container, or to a base cup and a cover cup fitted to a plastic container, or to a plastic container and the base cup or the cover cup. A plastic container with a handle, in which a short bottle-shaped handle is inserted into the holes of an upper handle holder and a lower handle holder, which are fixedly attached to the container, the handle having the upper handle at the upper end thereof. A flange portion is provided that rides on the upper surface of the side wall portion of the holder, and a hook portion having a substantially U-shaped cross section is provided at the lower end to clamp the front wall portion of the lower grip tool holder when the grip tool is gripped and bent. A hole is provided on the front surface of the handle, and extends downward from the upper end of the handle to near the lower end of the front wall of the upper handle holder, and is slightly smaller than the depth of the hole of the upper handle holder. The upper protrusion has a small wall thickness, and the vertical height is approximately 8-10 mm.
cm, the wall thickness is approximately equal to that of the upper protruding part, and an I-shaped central protruding part is formed, which includes upper and lower ends extending in the width direction and a main part extending in the vertical direction, and the central protruding part and the central protruding part are The object of the present invention is to provide a plastic container with a handle, characterized in that a portion between the upper protrusion and the hook is relatively thin and flexible.

The present invention will be described below with reference to the drawings which are examples.

In FIGS. 1 and 2, 1 is a plastic bottle, 2 is a base cup, and 3 is a cover cup. The plastic bottle 1 has a relatively large capacity (for example, about 1 to 10 liters) and is formed by biaxially stretching and blow molding a bottomed parison made of, for example, polyethylene terephthalate, and has a hemispherical bottom 1a and a container. It has a hemispherical shoulder portion 1b, and has a shape that does not easily deform even when it is filled and sealed with positive internal pressure (that is, produces an internal pressure higher than atmospheric pressure) contents such as beer or carbonated drinks. The base cup 2 is installed to ensure the upright stability of the plastic bottle 1, and is made of plastic, and the upper end 2a of the base cup 2 is fitted onto the upper end 1a' of the bottom 1a. Further, the bottom annular inner protrusion 2b of the base cup 2 is located at the bottom 1.
It is bonded to the corresponding portion of a through an adhesive layer (not shown). The cover cup 3 is made of plastic, and the inner short cylindrical part 3a is attached to the neck ring 1 of the plastic bottle 1.
c, and the lower end portion 3b is fitted on the shoulder portion 1b.
, which, in cooperation with the base cup 2, gives the plastic bottle 1 an overall barrel-shaped appearance.

Near the lower end 3b of the cover cup 3, an upper handle holder 4 (hereinafter referred to as upper holder) is integrally formed (for example, by injection molding), and near the upper end 2a of the base cup 2, a lower handle is formed. A tool holder 5 (hereinafter referred to as a lower holder) is integrally formed. In addition,
The cover cup 3 and the base cup 2 are assembled to the plastic bottle 1 so that a straight line connecting the centers of the upper holder 4 and the lower holder 5 is parallel to the axial direction of the plastic bottle 1. The lower holder 5 has a hole 6, has a rectangular cross section (elongated in the circumferential direction) (see FIG. 3), and has a side wall 5a extending above the front wall 5b. The upper holder 4 also has a hole 7 and is formed in the same shape and dimensions as the lower holder 5, except that the side wall 4a extends below the front wall 4b. There is.

In each of the holes 7 and 6 of the upper holder 4 and the lower holder 5, a short barrel-shaped handle 8 is slidably inserted. The handle 8 is made of flexible plastic, such as polyethylene, polypropylene, or soft polyvinyl chloride, and as shown in FIG. 4, the upper end 8a is provided with a flange 9, and the lower end 8b is There is a hook part 1 that is almost U-shaped in cross section.
0 is set.

As clearly shown in FIG. 1, the flange portion 9 rides on the upper surface 4a' of the side wall portion 4a of the upper holder 4 to prevent the handle 8 from falling. Further, the width of the portion of the handle 8 other than the flange portion 9 is determined to be slightly smaller than the width of the hole portion 7. An upper protrusion 8c is formed downward from the center of the upper end 8a to near the lower end 4b' of the front wall 4b, and the thickness of the protrusion 8c is slightly smaller than the depth of the hole 7. Therefore, when the handle 8 is inserted into the hole 7, no large wobbling occurs. At the front of the central part of the handle 8,
An I-shaped central protrusion 8d is formed, which includes an upper end and a lower end extending in the width direction, and a main part extending in the vertical direction, and the wall thickness at this part is equal to that of the upper protrusion 8c.
approximately equal to the husband of the husband, and its height in the vertical direction is approximately 8
~10cm, which is approximately equal to the sum of the widths of four fingers excluding the thumb.

The hook portion 10 is located below the lower holder 5, and the depth of the concave portion 11 of the hook portion 10 (distance in the radial direction of the plastic bottle 1) is set to be slightly larger than the thickness of the front wall portion 5b of the lower holder 5. has been
Therefore, as shown in FIG. 5, when the central part of the handle 8 is grasped by hand, the lower end 8b of the handle 8 is pulled up, and the handle 8 is bent, the hook part 10 touches the front wall part 5b. It's like being held in place. Upper part 8e and hook part 1 located between upper end part 8a and central protrusion part 8d
The lower part 8f located between the center protruding part 8d and the lower part 8d is formed to be relatively thin, so when the handle tool 8 is gripped and pulled outward in the radial direction, the upper part 8e and the lower part 8f are mainly folded. The central portion where the central protruding portion 8d, which is mainly in contact with the hand, is located is only slightly curved, so that it feels good in the grip and can be gripped reliably. Lower part 8f
The vertical height of the hook 1 is determined by gripping the handle 8.
A space 12 between the plastic bottle 1 and the bent handle 8 is created when the plastic bottle 1 and the front wall 5a are engaged.
(See Figure 5) to the extent that your fingers can fit inside with some margin (for example, about 4 to 5 inches).
cm) determined. When attaching the handle 8, the hook portion 10 is pushed into the holes 7 and 6 of the upper holder 4 and the lower holder 5 from above, but in order to ensure smooth pushing,
The lower front surface of the hook portion 10 is a curved portion 13.

The present invention is not limited to the above embodiments, and the plastic container may be a wide-mouthed plastic bottle or a cup-shaped container. Alternatively, the upper holder and the lower holder may be directly fixed to the plastic container. Furthermore, the upper holder may be fixed to the plastic container and the lower holder to the base cup, or conversely, the upper holder may be fixed to the cover cup and the lower holder to the base cup. It may be hot. Further, the shape of the cover cup and the base cup can also be arbitrary.

In the plastic container with a handle of the present invention, when the handle is not gripped, the bag-like handle approaches the plastic container and extends in the axial direction of the plastic container, so that the volume for storing the container is particularly large. There is no risk of large increases, and there is no problem of having to reduce the internal volume of the container due to the provision of a handle.

and on the front surface of the handle, extending downward from the upper end to near the lower end of the front wall of the upper handle holder;
In addition, since the upper protrusion is formed with a thickness slightly smaller than the depth of the hole of the upper handle holder, a large amount of wobbling occurs when the handle is inserted into the hole of the upper handle holder. It has the effect of not being there.

Furthermore, an I-shaped central protrusion is formed on the front surface of the handle, and the height in the vertical direction is approximately equal to the sum of the widths of four fingers excluding the thumb, and the wall thickness is approximately equal to that of the upper protrusion. The portion between the protrusion, the upper protrusion, and the hook is relatively thin.

Therefore, even if a protrusion is formed, it is possible to insert the handle into the hole of the upper handle holder, and when the handle is gripped and pulled outward in the radial direction, The thin-walled upper part 8e and lower part 8f are easily bent, and the central part reinforced by the central protrusion where the four fingers mainly come into contact has only a slight bend, giving a good grip feeling and making it easy to grasp. This has the effect of being able to be carried out easily and reliably.

Furthermore, the central protrusion is I-shaped, and its upper and lower ends extend in the width direction, and these widthwise protrusions particularly reinforce the upper and lower end portions of the handle, making it easier to grip the handle. I want to do it,
As shown in FIG. 5, the grip is sharply curved in the relatively thin upper part 8e and lower part 8f near these parts, resulting in an improved grip feeling.

As described above, the handle is not uniformly thick all over, and most of the handle is thin except for the parts that require thick walls, so it has the advantage of reducing material costs.
