Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a belt mounting structure of a Styrofoam box for accommodating and carrying food and the like.

[0002]

[Prior art]

 To attach the string of a conventional Styrofoam box, a bulging belt attachment part is provided in the upper center of the outer side wall of the body opposite to each other. Two through holes each, and the upper end of the string inserted into one through hole is inserted into the adjacent through hole from above, and then a knot is provided at each end of the string so that the string does not come out of the through hole. As shown in the figure, the sack was formed, and the shackles on both sides of the box were aligned and grabbed by the hand to lower the box.

[0003]

[Problems to be solved by the device]

 Styrofoam boxes have good heat insulation and are indispensable for storing foods, especially fresh foods such as fish and vegetables, and are often used for storing easily fragile items that also have buffering properties. In order to carry the Styrofoam box, the handle formed of a string as described above was conventionally used.

However, in the conventional structure, the weight of the knot of the string is heavy, and the load is applied around the lower end of the through hole that receives the knot. Therefore, in order to support this, a considerable thickness is required around the lower end of the through hole. However, there is a drawback that the periphery of the lower end of the through hole is damaged unless the belt mounting portion which is largely bulged is provided, and therefore a large amount of material is required.

In view of the above points, according to the present invention, the weight of the box received by the belt mounting portion is not supported at one point of the belt mounting portion, but is supported at several points to reduce the load and the belt mounting portion is small. In addition, it aims to provide a belt mounting structure for a Styrofoam box that saves material and materials.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention is provided with a bulging belt mounting part at the center of the outer upper part of the opposite side walls of the box body, and the taper dovetail groove that opens downward is fixed to this belt mounting part. It is formed toward the lower end from the lower surface of the bearing, leaving the height of the bearing, and has tapered downward fitting surfaces that fit into the dovetail on both sides, and the abutment surface that abuts the lower surface of the bearing is the upper surface. The end portion of the belt is attached to the belt attaching tool provided in, and the belt attaching tool is detachably provided in the dovetail groove.

Further, according to the present invention, a dovetail groove that extends to the tapered surface of the dovetail groove and has a taper shallower than the dovetail groove is formed on the outer wall surface of the support portion, and the taper fitting that fits into the dovetail groove of the support portion is formed. The pressing plate having the surfaces on both sides and having the contact surface with the outer wall surface of the support portion is formed on the outer surface of the upper surface of the belt attachment.

[0008]

[Action]

 To explain the operation of the present invention, if the belt attachment provided at the end of the belt is inserted from below the dovetail groove of the body belt attachment, the abutting surface of the upper surface of the belt attachment becomes the lower surface of the bearing. Abut, and the tapered mating surfaces on both sides of the belt fitting fit into the dovetail.

When the box is lifted by the belt, the weight of the box is applied to the abutment surface of the upper surface of the belt attachment, but not only the abutment surface but also the dovetail groove is a downward opening taper. As a result, the tapered mating surfaces on both sides also receive weight, and therefore many surfaces also receive weight, which imposes an unreasonable burden on the lower surface of the bearing part of the belt mounting part of the box that comes into contact with these surfaces and the dovetail groove. It does not take.

Further, since the dovetail groove is formed on the outer wall surface of the support part, and the dovetail groove is fitted with the pressing plate provided on the outer side of the upper surface of the belt attachment, and the pressing plate is in contact with the outer wall surface. When the box is lifted by the belt, the lower part of the belt attachment tries to expand outward due to the tensile force of the belt, but the pressing plate is pressed against the outer wall surface of the support portion to prevent the expansion.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a main part of a belt mounting structure of a styrofoam box of the present invention, FIG. 2 is a vertical sectional front view of the same, FIG. 3 is a partial bottom view of the same as above, and FIG. 4 is a perspective view of a belt mounting tool. 5 is a plan view of the same as above.

According to the present invention, a belt mounting portion 4 is formed integrally with the side wall 3 so as to bulge outward at the center of the outer upper side of the side wall 3 of the body 1 of the Styrofoam box composed of the body 1 and the lid 2. Has been done. The belt mounting portion 4 is formed with a tapered dovetail groove 6 that opens downward toward the lower end from the lower surface of the supporting portion 5 with a certain height left above. Further, a taper dovetail groove 7 is formed on the outer wall surface of the support portion 5 so as to extend from the tapered surface of the dovetail groove 6 and is shallower than the dovetail groove 6.

Reference numeral 8 denotes a plastic belt attachment, and the belt attachment 8 has on both sides thereof a downward-opening tapered fitting surface 9 that is detachably fitted to the dovetail groove 6, and its upper surface. In addition, it is a gate type having a horizontal butting surface 10 that abuts the lower surface of the support portion 5, and a mounting rod 12 for fixing the end portion of the belt 11 is provided between the fitting surfaces 9 on both sides.

Further, outside the abutting surface 10 of the belt attachment 8, there are tapered fitting surfaces 13 on both sides that fit into the dovetail groove 7 of the bearing 5, and the outer wall surface of the bearing 5 is abutted. A pressing plate 15 having an abutting surface 14 that contacts is provided integrally with the belt attachment 8.

[0015]

EFFECTS OF THE INVENTION According to the present invention, the weight of the box is received not only by the abutting surface on the upper surface of the belt attachment but also by the tapered fitting surfaces on both sides, which is one point like a conventional cord. Compared with the one that receives the weight of the box, the belt mounting part does not have an unreasonable burden, and the belt mounting part is also small, which saves materials and is economical. In addition, since the belt attachment is provided with a pressing plate, when the box is lifted by the belt, the belt attaching device tries to swell outward due to the tensile force of the belt, but the pressing plate causes the outside wall surface of the support portion to swell. The dovetail groove is also prevented from being damaged because it is pressed against and is blocked. Also, since the belt attachment is detachable in the dovetail, it can be stacked if it is not used for carrying, and it can be used as a normal Styrofoam box.
