Description

[Detailed Description of the Invention] The present invention relates to a can that accommodates sliver by coiler motion during the drawing process in spinning.

In general, this type of can has a cylindrical container made of paper fiber, and the bottom part has a double-layered structure made by polymerizing a hakama on the outer circumferential surface of the container, for example, as stipulated in Japanese Industrial Standards (JISL5133). In most cases, a ring-shaped bottom reinforcing metal fitting with a J-shaped cross section is attached to the bottom part of the bottom part, and is secured together with rivets. They were easily deformed, such as causing dents when they came into contact with each other. Such deformation makes it difficult to stand upright, increases rotational vibration when the can is used, makes it difficult to accommodate the sliver, and ultimately makes the can unusable.

Therefore, the present invention involves fitting an annular metal band around the outer periphery of the bottom of the container, bending the lower part of the peripheral side wall that is bent downward at the periphery of the metal bottom plate outward, and then folding it back inward. By forming a reinforced edge with a structure in which the tip is press-fitted to the metal band, it has a structure that is hard to deform, can always be kept upright, and has little rotational vibration during use, making it possible to use a sliver. It is designed so that it can be accommodated regularly and normally.

Embodiments of the present invention will be described below with reference to the drawings.
In the figure, 1 is a cylindrical container made of paper fiber, 2 is a bottom plate fixed to the inner bottom of the container, 3 is a spiral spring whose lower end is attached to the bottom plate 2, and 4 is attached to the top of the spring 3. This tray is made of synthetic resin, and its lower end is secured to the upper end of traction cables 5, 5 which are secured to the outer periphery of the bottom plate 2 so that its upper surface protrudes a predetermined length from the opening edge of the cylindrical container 1. .
6 is a small-diameter annular metal band that is in close contact with the inner circumferential surface of the opening edge of the cylindrical container 1, and 7 is an annular, large-diameter metal band that is in close contact with the outer circumferential surface of the opening edge. The upper edge of the small-diameter metal band 6 is bent outward and downward, and then folded back inward to form a hollow reinforcing edge 6a, and its tip is brought into pressure contact with the outer peripheral surface of the large-diameter metal band 7. Further, the lower end edge of the large-diameter metal band 7 is curled outward to form a winding portion 7a. Furthermore, the lower end edge of the small diameter metal band 6 is curved outward facing the winding part 7a to form a locking piece part 6b, and the locking piece part 6b and the winding part 7a form a locking piece part 6b that is connected to the cylindrical container 1. Attach it to the wall. 8
is a tube ring made of an elastic material such as synthetic resin that is fitted onto the outer peripheral surface of the large diameter metal band 7, and the outer peripheral edge of the tube ring 8 is located further outward than the outer peripheral surface of the reinforcing edge 6a of the small diameter metal band 6. It is bulged out.

As shown in FIG. 3, the bottom of the cylindrical container 1 has a double structure by bending the wall surface outward and surrounding it with a hakama 9 of a required height.

Reference numeral 10 designates an annular bottom metal band that is in close contact with the outside of the hakama 9, and its upper edge is curled outward to form a winding portion 10a. On the other hand, the lower part of the circumferential side wall 2a formed by bending downward on the periphery of the bottom plate 2 is bent outward and further folded inward to form a hollow bottom reinforcing edge 2b. 2
The tip of b is pressed against the lower part of the outer peripheral surface of the bottom metal band 10. 11 is the bottom metal band 10, the hakama 9,
These rivets are used to fasten the circumferential side walls 2a of the cylindrical container 1 and the bottom plate 2 to each other, and are used to fasten the cylindrical container 1 and the peripheral side walls 2a of the bottom plate 2 together at about six locations at the same intervals as shown in FIG.

Further, the outer diameter of the winding portion 10a of the bottom metal band 10 and the bottom reinforcing edge 2b are set to be equal to the outer diameter of the tube ring fitted to the opening edge, thereby making it possible to When the cans are arranged adjacent to each other, they can be stood upright with no gaps between the upper and lower ends of each can. Therefore, when a large number of cans are arranged in a line on a conveyor and transported in a spinning factory, the cans will not fall out of line and tilt even if pressed from behind.

As described above, the spinning can of the present invention has a ring-shaped metal band fitted onto the outer circumferential surface of a hakama that is superimposed on the bottom wall of a cylindrical container, and a bottom plate that is in contact with the inner circumferential surface of the bottom of the container. The lower part of the circumferential side wall is bent outward and then folded back inward to form a reinforcing edge, which is secured and fixed with rivets to wrap around and protect the bottom of the container. Furthermore, the hollow part formed inside the reinforcing edge and the metal band winding part at the outer periphery can absorb and reduce shock, preventing the cans from coming into contact with each other, etc. This can also prevent deformation from occurring. Thus, the can of the present invention has less rotational vibration during use and can accommodate the sliver normally.
Moreover, it has the advantage of being able to be used stably for a long period of time.
