Description

【０００１】
【発明の属する技術分野】
本発明は、容器入り粉末あるいは顆粒状製品の計量スプーンであって、板紙等シート状物を打ち抜き、折り曲げ、組み立ててなる紙製計量スプーンに関する。
【０００２】
【従来の技術】
従来から家庭用合成洗剤等は市販されるに際し、その適量使用のため計量スプーンを附属させることが一般的に行なわれ、通常包装容器内にプラスチック製のスプーンが投入されていた。しかしながら最近では、日常的に使い捨てられる前記プラスチック製計量スプーンは廃棄面からも問題とされている。
【０００３】
前記のような問題に関しては、廃棄処理が容易な点で、これまでも各種の紙製計量スプーンが提案されている。例えば特開平１０−１９６３６号や特開２０００−１６２０１６号公報記載の発明に示されるごとく、板紙を折り曲げて把持部と計量部とを形成した組立式計量スプーンで、いずれも把持片を中央部で折り曲げ固定し、かつ両把持片の前縁部に連設した計量板および一対の側板で形成される計量部分を有するものである。しかしながら、これらは計量部分と把持部分とがほぼ同一の平面状で形成されるため、通常の外装カートン内で計量操作を行う際には手指に洗剤が付着しやすく、また残量が少なくなった場合には外装カートン深くに手指を入れる必要があり、かつ洗剤をすくい取る操作が難しいという問題があった。
【０００４】
また実用新案登録第２５３３９９２号公報記載の考案は、方形の底板と一対の側板と前板、後板とからなる計量部と、後板に連接した取手部と両側に連設された取手部補強板からなる紙製スプーンが示されている。それぞれの構成板が接着されて形成されるスプーン形状は、従来のプラスチック製スプーンと近似した形状となるが、前述のごとく接着を要する構造のため、予め専用の接着装置を用いて接着するか、同じく予め人手により接着作業を行なうものである。このため、特別な組み立て装置を必要とするか、人的作業を必要とするものであるとともに、予め立体に形成することを特徴とするもので、一般消費者が平板なブランク状態から簡便に組み立てられるものでは無いという欠点があった。
【０００５】
【発明が解決しようとする課題】
そこで、本発明は、上記問題を解決するためになしたものであって、その目的とするところは、粉末あるいは顆粒状製品に附属される計量スプーンにおいて、板紙等を用いて製作され、平板な状態で輸送あるいは販売に供されるとともに、簡便に組み立てられ、計量操作性に優れしかも使用後の廃棄が容易な紙製計量スプーンを提供する。
【０００６】
【課題を解決するための手段】
上記課題を解決するため、請求項１の発明は、一枚の紙製ブランクを組み立ててなる紙製計量スプーンであって、矩形の底板と、該底板の対向する二辺のそれぞれに連設した側板、前記底板の他の一辺に連設した先端側を把持部となす後板と、前記側板の後板側のそれぞれに連設した後板支持片と、前記後板の把持部両側端に連設され組み立て時にその下端部が後板支持片の上端部と係合する把持部支持片とを有し、前記矩形の底板と、該底板の対向する二辺から立ち起こされたそれぞれの側板と、他の一辺から立ち起こされた後板で計量部分を形成し、前記側板に連設された後板支持片と、前記把持部側端に連設された把持部支持片とをそれぞれ外折りして係合することで把持部分を形成し、紙製計量スプーンとして使用するものである。
【０００７】

【０００８】
請求項３の発明は、前記後板の把持部の上端近傍に差込用溝を穿設するとともに、前記一方の把持部支持片の上端延長上には前記差込用溝に差し込まれる差込片を連設したことを特徴とする請求項１記載の紙製計量スプーンであって、前記側板に連設された後板支持片と、前記後板の把持部に連設された把持部支持片とをそれぞれ外折りして重合するとともに、最も外側に重合される把持部支持片の上端延長上に設けた差込片を、前記後板の把持部の上端近傍に穿設した差込用溝に差し込んで把持部分を形成するものである。

BACKGROUND OF THE INVENTION
The present invention relates to a measuring spoon for powder in a container or granular product, and relates to a measuring spoon made of paper, such as paperboard, which is punched, bent and assembled.
[0002]
[Prior art]
Conventionally, when household synthetic detergents and the like are marketed, a measuring spoon is generally attached for use in an appropriate amount, and a plastic spoon is usually placed in a packaging container. However, recently, the plastic measuring spoons that are disposable on a daily basis are also problematic from the viewpoint of disposal.
[0003]
Regarding the above problems, various types of paper measuring spoons have been proposed so far in terms of easy disposal. For example, as shown in the invention described in Japanese Patent Application Laid-Open No. 10-19636 and Japanese Patent Application Laid-Open No. 2000-162016, each of the assembly-type measuring spoons is formed by folding paperboard to form a gripping part and a measuring part. It has a measuring portion that is formed by a measuring plate and a pair of side plates that are bent and fixed and connected to the front edge of both gripping pieces. However, since the weighing part and the gripping part are formed in substantially the same flat shape, the detergent easily adheres to the fingers when the weighing operation is performed in a normal outer carton, and the remaining amount is reduced. In some cases, it is necessary to put a finger deeply into the outer carton, and the operation of scooping the detergent is difficult.
[0004]
In addition, the invention described in Utility Model Registration No. 2533999 discloses a measuring part composed of a square bottom plate, a pair of side plates, a front plate and a rear plate, a handle portion connected to the rear plate, and a handle portion reinforcement provided on both sides. A paper spoon made of board is shown. Spoon shape formed by bonding each component plate is a shape that approximates the conventional plastic spoon, but because of the structure that requires adhesion as described above, it can be bonded in advance using a dedicated bonding device, Similarly, the bonding work is performed manually in advance. For this reason, it requires special assembly equipment or requires human work, and is characterized by being formed in advance in a three-dimensional form. There was a drawback that it was not.
[0005]
[Problems to be solved by the invention]
Therefore, the present invention has been made to solve the above problems, and the object of the present invention is to produce a flat plate made of paperboard or the like in a measuring spoon attached to a powder or granular product. Provided is a paper measuring spoon which can be transported or sold in a state, is easily assembled, has excellent weighing operability, and can be easily discarded after use.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the invention of claim 1 is a paper measuring spoon formed by assembling a single paper blank, and is continuously provided on each of a rectangular bottom plate and two opposite sides of the bottom plate.

The paper measuring spoon according to claim 1, wherein a rear plate support piece continuously provided on the side plate and a gripping portion support piece continuously provided on the gripping portion are respectively folded outward. While having a substantially triangular prism or a substantially triangular frustum-like structure, the holding protrusion is locked and fixed in the locking notch to form a grip portion.
[0008]
According to a third aspect of the present invention, an insertion groove is formed in the vicinity of the upper end of the grip portion of the rear plate, and is inserted into the insertion groove on the upper end extension of the one grip portion support piece. The paper measuring spoon according to claim 1, wherein a piece is provided continuously, a rear plate support piece provided continuously to the side plate, and a grip portion support provided continuously to a grip portion of the rear plate. Each of the pieces is folded and polymerized, and an insertion piece provided on the upper end extension of the gripping part supporting piece that is superposed on the outermost side is drilled in the vicinity of the upper end of the gripping part of the rear plate. A gripping portion is formed by being inserted into the groove.
[0009]
The invention according to claim 4 is the paper measuring spoon according to any one of claims 1 to 3, wherein an angle formed by the bottom plate side folding line and the rear plate supporting piece side folding line forming the respective side plates is an obtuse angle. The angle formed by the weighing part bottom plate and the rear plate having the front end side as the gripping part becomes an obtuse angle, thereby giving excellent weighing operability.
