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.

= Generally, this type of can is made of a cylindrical container made of fibrous board such as vulcanized fiber or resin-reinforced laminated paper, and the opening edge of the container is bent outward to form a double part, with a soft steel wire, etc. In most cases, a top ring is formed by welding a round bar into an annular shape and is reinforced by going around it.
However, it still lacked strength and was easily deformed due to contact between cans or falling over.

This deformation has the drawback of increasing rotational vibration when the can is used, making it difficult to accommodate the sliver, and ultimately rendering the can unusable.

The present invention has a structure in which annular metal bands are fitted to the inner and outer peripheral surfaces of the opening edge, and a tube ring made of an elastic material is fitted to the outer peripheral surface of the outer metal band.
It is robust enough to resist deformation, reduces rotational vibration during use, and allows the sliver to be stored properly.

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 is a cylindrical container made of fiber board, 2 is a lower support plate fixed at the inner bottom of the container, 3 is a spiral spring whose lower end is attached to the lower support plate 2, and 4 is the spring 3.
It is a synthetic resin saucer attached to the top of the.

The lower end of the saucer 4 is engaged with the upper end of traction cables 5, 5 which are engaged with the outer periphery of the lower support plate 2 so that the upper surface of the saucer 4 protrudes a predetermined length from the opening edge of the cylindrical container 1.

In FIG. 2, 6 is an annular small-diameter metal band that is in close contact with the inner peripheral surface of the opening edge of the cylindrical container 1, and γ is a small diameter metal band that is closely attached to the inner peripheral surface of the opening edge of the cylindrical container 1.
It is an annular large-diameter metal band that closely fits around the outer peripheral 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.

Further, the lower end edge of the small diameter metal band 6 is curved outward to correspond to the winding part 7a to form a locking piece part 6b, and the locking piece part 6b and the winding part 7a are connected to the cylindrical container 1. The wall surface of the wall is pinched.

Reference numeral 8 denotes a tube ring made of an elastic material such as synthetic resin that is fitted onto the outer circumferential surface of the large-diameter metal band 7, and the outer circumferential edge of the tube ring 8 is outer than the outer circumferential surface of the reinforcing edge 6a of the small-diameter metal band 6. It bulges out towards the side.

Note that the inner diameter α of the small diameter metal band 6 is equal to the inner diameter β of the cylindrical container 1.
This is to prevent any step from forming on the inner surface of the cylindrical container 1.

In addition, the bottom of the cylindrical container 1 has a double wall by bending the wall surface outward and installing a hakama 9 of a required height around the bottom, as shown in FIG. 2 mounting piece 2a with rivets 10
A metal bottom rim 11 having a J-shaped cross section is fitted to the bottom of this double wall, and the bottom rim 11
The slider 12 is made of nylon resin and has a shape that covers it.

As mentioned above, the can of the present invention has a small-diameter annular metal band fitted to the inner circumferential surface of the opening edge of a cylindrical container made of fiberboard, and a large-diameter annular metal band fitted to the outer circumferential surface of the opening edge. At the very least, since the opening edge is protected on both the inside and outside surfaces, an extremely robust structure can be achieved.Moreover, the winding formed on the lower edge of the large-diameter metal band and the engagement formed on the lower edge of the small-diameter metal band can be achieved. Since the wall surface of the cylindrical container is clamped and fixed with the stopper part, each metal band does not fall off.

The elasticity of the tube ring fitted on the outer circumferential surface of the large-diameter metal band provides a buffering function when the cans come into contact with each other or fall, thereby protecting the opening edge from impact.

Note that if the tube ring is made of synthetic resin, it can be colored as desired, so it can be colored differently depending on the product type and lot.

They can be color-coded according to product or other needs, and since they are mounted on the outer peripheral surface near the edge of the opening, they are conspicuous and easy to identify.

It also has the advantage that the cans, which are generally formed in a single color, can be made colorful, thereby making the atmosphere of the spinning factory more comfortable.
