DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is an illustration of a method of using a cup sleeve according to an embodiment of the present invention. The cup sleeve 1 shown in FIG. 1A has a tubular shape whose upper and lower sides are open, and the upper side 11 has a larger diameter than the lower side 12. On the other hand, the frustoconical cup 9 such as a beverage paper cup has an open upper end 91 and a closed lower end 92, so that food and drink can be stored therein.
The upper end 91 has a larger diameter than the lower end 92.

As shown in FIG. 1B, the lower end 92 side of the frustoconical cup 9 is inserted into the cup sleeve 1, and the cup sleeve 1 is fitted to the outer periphery of the frustoconical cup 9. As a result, the cup sleeve 1 acts as a heat insulating material, and the user can easily grasp and carry or drink the contents even when a hot drink is contained in the cup.

FIG. 2 is a development view of the cup sleeve. As shown in the drawing, the cup sleeve 1 has a band shape (a straight band shape) in which an upper side 11 and a lower side 12 are linear in a developed view. Further, an insertion piece 13 and an insertion opening 14 are provided at both ends in the longitudinal direction. Insert piece 13
Has a width (length in the direction of arrow A in FIG. 2) equal to or slightly smaller than the length of the insertion port 14 (length in the direction of arrow B in FIG. 2). It can be inserted into the inside of 14. The angle formed by the width direction of the insertion piece 13 shown by the arrow A and the length direction of the insertion opening 14 shown by the arrow B is determined by the inclination angle of the side surface of the frustoconical cup to which this cup sleeve is applied. The cup sleeve 1 may be provided with planned bending lines 15 and 16 such as a half-cut score line, if necessary.

It is desirable that the material of the cup sleeve 1 be heat-insulating, lightweight, and substantially non-stretchable. Examples include single-sided corrugated board, cardboard, and foaming resin.

Next, an assembling procedure of the cup sleeve 1 will be described with reference to FIGS.

FIG. 3 is a plan view showing the assembled state of the cup sleeve. When the cup sleeve 1 is rolled to form a tubular body with the depth direction of the paper of FIG. 2 facing outward and the insertion piece 13 is inserted into the insertion opening 14 from the outside of the sleeve, the state shown in FIG. 3 is obtained. FIG. 3 particularly shows a case where the planned bending lines 15 and 16 of FIG. 2 are folded in valleys.
By thus bending the cup sleeve by flattening the cup sleeve, it is compact and convenient for storage and transportation, and the risk of damage even if a load is applied during storage or transportation is reduced. After assembling in the state of FIG. 3, if necessary, the vicinity of the insertion piece 13 and the insertion opening 14 which are the connecting portions of both ends are adhered to each other with an adhesive or the like.

The cup sleeve 1 is thus completed. As shown in FIG. 3, both ends of the cup sleeve are joined so that the longitudinal directions (E direction and F direction in FIG. 3) of the cup sleeve intersect each other. ing. As a result, the height of the upper side 11 and the height of the lower side 12 are not constant in the circumferential direction of the sleeve. In this embodiment, the uneven heights make it very easy to insert the frustoconical cup 9 into the folded cup sleeve 1 of FIG. Further, even in the use state of FIG. 1 (b), the sleeve position can be held at a high position or a low position according to the user's preference, and the flexibility of holding the cup with a small amount of material can be obtained. Higher cup sleeves can be manufactured.

As shown in FIG. 1 (b), the insertion piece 13 is designed to be slightly upward when used. Therefore, the operation direction for separating the insertion piece 13 from the insertion state to the open state is the oblique downward direction (arrow C direction). On the other hand, when used, the cup sleeve 1
The direction of the force actually received by the both end joints is the horizontal direction (direction of the arrow D) along the outer periphery of the cup 9 as a result of the downwardly gravitational force of the cup 9 having the truncated cone shape. Since the direction of the force required to release the coupled state and the direction of the force actually received by the coupled portion are different, the cup sleeve 1 of the present embodiment is unlikely to come off during use. There is.

Further, as shown in FIG. 1 (b), when the cup sleeve 1 is attached to the cup 9, the insertion direction of the insertion piece 13 with respect to the insertion opening 14 (direction of arrow C).
The inclination angle of is smaller than the inclination angle (in the direction of arrow G) at the end portion of the cup sleeve 1 provided with the insertion piece 13. This makes it easy to insert the insertion piece 13 into the insertion opening 14 when assembling the cup sleeve.

In this embodiment, when the insertion piece 13 is inserted into the insertion port 14, the upper side of the cup sleeve 1 or its extension line intersects at points 19 and 19 shown in FIG. This point 19 becomes the highest point 19 at the time of attachment to the cup 9 shown in FIG. 1 (b). The insertion piece 13 is formed at a portion where the cup sleeve 1 extends in the longitudinal direction from the point 19, and the insertion port 14 is formed closer to the center in the longitudinal direction of the cup sleeve than the point 19. If formed in this way, the insertion of the insertion piece 13 into the insertion opening 14 becomes easier.

The cup sleeve 1 is replaced by a frustoconical cup 9
The inclination angle of the cup sleeve 1 when it is attached to is gentle at the central portion in the longitudinal direction, and the inclination angle becomes steeper toward the end side. At the above-mentioned point 19 where both ends of the upper side of the cup sleeve 1 intersect with each other, the inclination angles of the cup sleeve are equal to each other.

Reference Example FIG. 4 shows a cup sleeve according to a reference example , in particular, a connection state of both end portions. This will be described in comparison with FIG.

In the embodiment of FIG. 3, the insertion piece 13 is inserted into the insertion opening 1.
4, the both ends are joined by being inserted into the cup 4, whereas in the reference example of FIG. 4, the notches 23 and 24 are alternately formed near the respective longitudinal ends of the cup sleeve 1.
Is formed, and both ends are joined by engaging them. In the reference example of FIG. 4, since both ends are supported at one point 27, it is possible to rotate about the point 27, and the angle formed by the longitudinal directions of both ends of the joint is uniquely determined. Absent. Therefore, if the both ends of the cup sleeve are bonded before the frustoconical cup is inserted, the cup sleeve cannot be accurately positioned, which is rather suitable for use without bonding the both ends. On the other hand, in the embodiment shown in FIG. 3, the upper end 17 and the lower end 18 of the insertion piece base are replaced by the upper end 17 and the lower end 18 of the insertion opening.
Can be supported by points. Therefore, if the root of the insertion piece 13 is inserted into the insertion port 14, the insertion piece 14 can be accurately positioned, and it becomes extremely easy to bond both ends in advance before inserting the truncated cone cup 9.

(Manufacturing Device) A manufacturing device for manufacturing the sleeve of the present invention is not particularly shown, but can process a material having substantially no elasticity into a shape as shown in the development view of FIG. Is. More specifically, a feeding section for feeding a predetermined number of blank materials, and a processing section for punching or cutting the material to form a straight band-shaped cup sleeve as shown in the development view of FIG. And a storage portion for stocking punched or cut straight sleeve sleeves for cups. In addition, if necessary, a portion for forming the planned bending lines 15 and 16, a portion for bending along the planned bending line, a portion for inserting the insertion portion 13 into the insertion opening 14, and a portion for bonding the joint portion are provided. It may be.
