本発明は、ダンボール箱を形成する場合の、該ダンボー
ル箱の長手側底板と巾側底板とを接着する方法に関する
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of bonding a longitudinal side bottom plate and a width side bottom plate of a cardboard box when forming the same.
従来、ダンボール箱を形成する場合には、まず１〕側底
板を内方へ水平に折り込み、次いで長手側底板を内方へ
水平に折り込んで前記巾側底板に重ね合せ、しかる後こ

」けることにより行なっていた。Conventionally, when forming a cardboard box, first 1) the side bottom plates are folded horizontally inward, then the longitudinal side bottom plates are folded inward horizontally and overlapped with the width side bottom plates, and then these longitudinal side bottom plates are folded horizontally inward; This was done by integrally securing the width and bottom plates with staples.

欠点があった。しかも、前記ｄ］側底板内部の補強リブ

これら補強リブが潰されてしまうと、運搬時の振動、衝

スで止め刊けると、そのホチキスの加締めた部分が必ず
ダンボール箱の内向側に突出するため、この突出部分に
よってダンボール箱内の収納物が傷ついてしまうという
欠点もあった。However, when the paper is stapled in this manner, the wavy reinforcing ribs inside the width side bottom plate and the wavy reinforcing ribs inside the longitudinal side bottom plate of the stapled part are crushed by the crimping of the stapler. This has the disadvantage that the strength (rigidity) of the bottom plate of the cardboard box is lost. Moreover, the reinforcing ribs inside the side bottom plate (d) and the reinforcing ribs inside the longitudinal side bottom plate provide a cushioning effect during transportation, which is an advantage of a cardboard box.
If these reinforcing ribs are crushed, vibrations, shocks, etc. during transportation will be applied to the items stored in the cardboard box through both bottom plates, making the items extremely susceptible to damage. There was a drawback. Furthermore, when a book is stapled together, the stapled portion always protrudes inward from the cardboard box, which has the disadvantage of damaging the items stored in the cardboard box.
そこで、近時、前記ホチキスで止め付けるのに代わり、
前記ＩＪ側底板とｆｉｆｉ記長手側底板との間にホット
メルトを介在させ、このホットメルトを加熱することに
より、巾側底板と長手側底板とを接着するという方法が
ある。Therefore, recently, instead of fixing with staples,
There is a method in which a hot melt is interposed between the IJ side bottom plate and the FIFI longitudinal side bottom plate, and the width side bottom plate and the longitudinal side bottom plate are bonded by heating this hot melt.
これによれば、前記ホチキスで止め付ける場合のように
、ダンボール箱の内面側に突出部分が形成されないから
、ダンボール箱内の収納物か傷ついてしまうということ
は解消されるが、しかし依然として巾側底板内部の補強
リプや長手側底板内部の補強リブが潰されてし−まうと
いう欠点がある。According to this method, there is no protruding part formed on the inner surface of the cardboard box as in the case of fixing with staples, so it is possible to avoid damage to the items stored in the cardboard box. There is a drawback that the reinforcing ribs inside the bottom plate and the reinforcing ribs inside the longitudinal side bottom plate are crushed.
つまり、ホントメルトで接着する場合には、０［■記［
１］側底板と１１０記長手側底板とを挾圧した状態で、
これらの聞に介在したホットメルトを加熱しなければな
らないので、結局「１コ側底板の補強リプや長手側底板
の補強リブは前記挟圧時に潰されてしまうのである。In other words, when bonding with true melt, 0 [■ mark [
1] With the side bottom plate and the 110 longitudinal side bottom plate pressed together,
Since the hot melt interposed between these parts must be heated, the reinforcing ribs on the bottom plate on the one side and the reinforcing ribs on the bottom plate on the longitudinal side end up being crushed during the squeezing.
しかも、このようなホットメルＦは、一度加熱によって
硬化させても、再度の加熱によって再び軟化して、接着
効果が低下するという性質があることから、夏季の運搬
時などには、ダンボール箱のｒｌＪ側底板と長手側底板

。Moreover, even if such Hot Mel F is once cured by heating, it will soften again by heating again, reducing the adhesive effect. The side bottom plate and the longitudinal side bottom plate peel off, causing an accident in which the bottom of the cardboard box falls out.
本発明は、このような事情があることに鑑みてなされた
もので、その目的とするところは、１１〕側底板の補強

を形成する場合の接着方法を提供することにある。The present invention has been made in view of the above circumstances, and has the following objectives: 11) Reinforcement lip of the side bottom plate and reinforcing rig of the longitudinal side bottom plate are crushed during bonding. To provide an adhesion method for forming a cardboard box, which can prevent the above 11] side bottom plates and longitudinal side bottom plates from being peeled off even when heated again. There is a particular thing.

である。In order to achieve this purpose, the present invention 1 consists of overlapping the longitudinal side bottom plate and the RLJ side bottom plate constituting the cardboard box with a thermosetting adhesive interposed between them. By applying the ultrasonic horn, which is the output end of the ultrasonic welder, to the overlapping part with the adhesive interposed, 1.
The longitudinal side bottom plate 1o and the side bottom plate 1) are glued together.
以下、本発明の一実施例を図面に基づいて説明する。Hereinafter, one embodiment of the present invention will be described based on the drawings.
第１図は、ダンボール箱を形成する前の状態を示す斜視

By applying heat and curing the thermosetting adhesive 4, both 1] side bottom plates 2.2 and both longitudinal side bottom plates 3, 3 are bonded to each other.
このようにして接着されたものが、第３図に示すように

収納物を安全に収納させておくことができる。Therefore, with such an adhesion method, when adhering the side bottom plate 2 and the longitudinal side bottom plate 3, there is no need to attach these bottom plates 2,
3, it is possible to effectively prevent the wavy reinforcing ribs 2b inside the rlj side bottom plate 2 and the wavy reinforcing ribs 3b inside the longitudinal side bottom plate 3 from being crushed. Therefore, the strength (rigidity) and cushioning effect of the bottom plate of the cardboard box l are not impaired in any way, and the items stored in the cardboard box can be safely stored.

。In addition, since the adhesive used to bond the width side bottom plate 2 and the longitudinal side bottom plate 3 is a thermosetting adhesive, it does not need to be heated again like the conventional Honmelt. Bottom plate 3
There is no possibility that the cardboard will peel off, and the items stored in the cardboard boxes can be transported safely even during transportation in the summer.

とができる等、実用上人なる効果を奏する閥のである。If so, the reinforcement ribs inside the width side bottom plate and the inside of the long side bottom plate;
Since the reinforcing ribs of the cardboard box 1 are not crushed, the strength and cushioning effect of the bottom plate of the cardboard box 1 are not impaired in any way, and the width side bottom plate and the long side bottom plate are once bonded together. It is a material that has many practical benefits, such as the fact that it does not peel off even if it is reheated, and the items stored in the cardboard box can be transported safely.
