Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention relates to a polyethylene bag that opens the mouth of a polyethylene bag to facilitate storage of articles.
The present invention relates to a device which can be carried and installed.

2. Description of the Related Art Conventionally, a garbage is stored in a metal basket or a car-mounted metal basket with a polyethylene bag inserted therein. Both are sturdy, but you have to pull them up to remove the garbage bag,
There were restrictions on where they could be used. For example, to store items while moving on uneven terrain, you had to work with a polyethylene bag in one hand.

[Problems to be Solved by the Invention] Commercially available polyethylene bags include those for general use and those containing 30% of calcium carbonate dedicated to garbage. Because it is extremely thin, 0.05 mm, it is difficult to keep the shape of the mouth of the bag constant, and it is difficult to store things. An object of the present invention is to provide a lightweight and portable device which can be easily opened for any kind of polyethylene bag except for the drawbacks of such a thin polyethylene bag.

[Means for Solving the Problems] A few centimeters of the end of the polyethylene bag 12 is folded back from the inside to the outside of the rectangular ring 1 over the entire circumference. Then, the polyethylene bag 12 becomes integral with the rectangular ring 1. Next, the clamp 3 is turned after the left and right short sides of the rectangular ring 1 integrated with the polyethylene bag 12 are respectively hung on the hanging brackets 2 of the left and right support brackets 4. The rectangular ring 1 is fixed to the support bracket 4 and is in a state of holding a polyethylene bag as shown in FIG. Further, in order to fix and use it in one place, as shown in FIG. 4, the polyethylene bag 12 with an open / hanger shown in FIG.

[Operation] Since the outer peripheral length of the rectangular ring 1 is substantially equal to the inner peripheral length of the polyethylene bag 12, the ring 1
The edge of the polyethylene bag which is folded back and adheres to the rectangular ring 1 from the outside. Since the polyethylene itself is also a material which does not easily expand, when the load is applied to the polyethylene bag 12 with the open hanger shown in FIG. The edge of the polyethylene bag does not come off from the side even if there is no hold down. The short side of the rectangular ring 1 presses the folded part of the polyethylene bag 12 at the contact surface with the hanging bracket 4, and the entire load of the polyethylene bag 12 is supported by the frictional force generated here and the frictional force with the pipe surface. ing. The pressure of the clamp 3 does not need to be unnecessarily high and damage to the bag membrane must be avoided. The frame 14 of the folding base 13 has a structure lacking a crosspiece on the side where the frame is taken in and out, so that the polyethylene bag 12 with an open hanger shown in FIG.

An embodiment of the present invention will be described below.

FIG. 3 shows an embodiment of the present invention.
Medium-sized calcium carbonate 30% polyethylene bag (800 x 650 x 0. 0) which is most frequently used in daily life.
Since the inner peripheral length of 03) was 1300 mm, the length ratio of the rectangular ring 1 used for this was selected to be 6: 5, and the dimensions and materials were as follows. Long side $ 37
5mm Short side ‥‥ 310mm Curvature radius at four corners ‥‥ 40mm Material ‥‥ Aluminum 8φ When powder or the like is packed into a bag, its shape becomes cylindrical. The ratio was 6: 5. Other dimensional ratios may be used.
The material is aluminum 8φ to reduce the weight, but iron, stainless steel, or other materials may be used for large bags. The rectangular ring 1 may be made of a material other than a pipe and having a shape suitable for the stress of the load. Since the dimensions of the polyethylene bag vary slightly depending on the manufacturer, it is more preferable that the rectangular ring has a structure in which the short side of the rectangular ring extends about 5 mm by a coil spring.

The hanging metal fitting 2 is attached to the inner surface of the supporting metal fitting 4 and supports the entire short side straight portion of the rectangular ring 1. The hanging width of the hanging fitting 2 must be equal to or larger than the pipe radius of the rectangular ring 1. The cross section of the suspension fitting 2 is preferably a semicircle that matches the diameter of the pipe, but may be L-shaped. When the clamp 3 is turned around the bolt 5, the pipe of the rectangular ring 1 is pressed against the suspension fitting 2 and fixed to the support fitting 4. The pressure of the clamp 3 can be adjusted by adjusting the force of the coil spring 6 with the nut 7. The clamp 3 may be a slide type or a clip type clamp as long as it can achieve the purpose of fixing the pipe without being a rotary type as shown in FIG. The edges of the hanging fitting 2 and the clamp 3 must be rounded to eliminate the risk of damaging the fabric of the polyethylene bag 12. Handle 11 is shaft 8
And the right and left support brackets 4 via the joint 9 and the shaft 10
As shown in FIG. 1, it is unsteady and unstable when nothing is attached as shown in FIG. 1. However, as shown in FIG.

FIG. 4 shows the folding table 13 of the device of the present invention.
This is an embodiment in which the device is placed and fixed for use. Folding stand 1
The height of the frame 14 of No. 3 was set to 560 mm. The reason for this is that when the release of the polyene bag 12 is 800.times.650 mm, the bag swells when packed, and the length of the bag is reduced by about 200 mm. Further, this is to prevent the bag 12 from being forcibly applied when an object in the bag is pushed from above and the edge of the bag 12 is torn or detached from the device.

[Effects of the Invention] When the device of the present invention is attached to a thin and difficult-to-handle polyethylene bag, the shape becomes easy to handle as shown in FIG. It can be used for pruning trees in places where you do not want to drop it down, and because it can be transported by hand, it can be used as a trash can for storage of things at party venues, construction sites and even at home.
