このような構成からなる紙基材Ｐは、まず、各緩衝部形成形状部２０１Ｐ、２０２Ｐの各部分２１１Ｐ〜２５１Ｐ、２１２Ｐ〜２５２Ｐが次のように折り曲げられて、緩衝部２が組み立てられる。図１及び図２を参照しながら説明すると、まず初めに、下フラップ部分１７１Ｐ、１７２Ｐに対して折れ線４０、４４を介して支持壁部分２１１Ｐ、２１２Ｐがそれぞれの内側面を内側にして略直角に折り曲げられて、下フラップ部分１７１Ｐ、１７２Ｐの先端に直角に支持壁２１Ｒ、２１Ｌが形成される。続いて、この支持壁２１Ｒ、２１Ｌに対して折れ線４６１、４６２を介して物品底部保護壁部分２２１Ｐ、２２２Ｐがそれぞれの内側面を内側にして略直角に折り曲げられて、物品底部保護壁２２Ｒ、２２Ｌが形成され、物品底部保護壁２２Ｒ、２２Ｌが下フラップ部分１７１Ｐ、１７２Ｐの内側面に沿って緩衝空間Ｓ、Ｓを介して配置される。これに続いて、物品底部保護壁２２Ｒ、２２Ｌに対して折れ線４７１、４７２を介して固定壁部分２３１Ｐ、２３２Ｐが固定部部分２４１Ｐ、２４２Ｐとともにそれぞれの内側面を内側にして略直角に折り曲げられて、固定壁２３Ｒ、２３Ｌが形成され、固定壁２３Ｒ、２３Ｌが物品底部保護壁２２Ｒ、２２Ｌと下フラップ部分１７１Ｐ、１７２Ｐとの間に配置される。このようにして各側面壁部分１２Ｐ、１４Ｐに対して折れ線３９、４３を介して各下フラップ部分１７１Ｐ、１７２Ｐがそれぞれの内側面を内側にして略直角に折り曲げられて、下フラップ１７Ｒ、１７Ｌが形成され、各固定壁２３Ｒ、２３Ｌが各側面壁部分１２Ｐ、１４Ｐの下端付近に当接され、各固定壁２３Ｒ、２３Ｌは固定部２４Ｒ、２４Ｌとともに各側面壁部分１２Ｐ、１４Ｐの下端付近に接着剤を介して接着固定される。この場合、各固定壁２３Ｒ、２３Ｌに固定部２４Ｒ、２４Ｌが一体的に設けられることで、各固定壁２３Ｒ、２３Ｌが各固定部２４Ｒ、２４Ｌの部分だけ各側面壁部分１２Ｐ、１４Ｐに対する接触面積が増大するので、各固定壁２３Ｒ、２３Ｌは各側面壁部分１２Ｐ、１４Ｐに対して強固に固定され、各支持壁２１Ｒ、２１Ｌとともに各物品底部保護壁２２Ｒ、２２Ｌを確実に支持することができ、緩衝部２の緩衝作用をより確実に発揮することが可能である。
次に、箱１の各部分１１Ｐ〜１９Ｐが折り曲げられて、箱１が組み立てられる。まず、後面壁部分１１Ｐに対して折れ線３１を介して右側面壁部分１２Ｐがそれぞれの内側面を内側にして略直角に折り曲げられて、後面壁１１及び右側面壁１２が形成される。続いて、この右側面壁１２に対して折れ線３２を介して前面壁部分１３Ｐがそれぞれの内側面を内側にして略直角に折り曲げられて、前面壁１３が形成される。続いて、この前面壁１３に対して折れ線３３を介して左側面壁部分１４Ｐがそれぞれの内側面を内側にして略直角に折り曲げられ、左側面壁１４が形成される。続いて、左側面壁１４に対して折れ線３４を介して接着片部分１５Ｐがそれぞれの内側面を内側にして略直角に折り曲げられて、接着片１５が形成され、この接着片１５が後面壁１１の他方の側縁の内側に接着剤を介して接着固定される。そして、後面壁１１及び前面壁１３に対して折れ線３７、４１を介して各下蓋部分１９１Ｐ、１９２Ｐがそれぞれの内側面を内側にして略直角に折り曲げられて、下蓋１９Ｒ、１９Ｌが形成される。これらの下蓋１９Ｒ、１９Ｌはそれぞれ、箱１の下面において、各下蓋１９Ｒ、１９Ｌの斜辺が当該下面の一方の対角線上に合わせられて略四角形状に組み合わせられ、各下フラップ１７Ｒ、１７Ｌの外側面に接着剤を介して接着固定される。ここまでの組み立てが終わった段階で、箱１の組み立ては一旦中断され、この後の組み立て及び必要箇所の接着固定は、箱１内部に薬瓶が収納された後に、引き続き行われる。
