Description

  The present invention relates to a synthetic resin fitting container.

  In particular, according to the present invention, an opening / closing piece that engages with each other is provided on the main body and the lid, and the lid can be easily opened by operating one of the opening / closing pieces. The present invention relates to a synthetic resin fitting container capable of closing a lid.

  Many containers with lids made of synthetic resin have been proposed and many have been put to practical use.

  In general, a container with a lid made of a synthetic resin includes a main body and a lid that are separated from each other, or a main body and a lid made of synthetic resin that are pivotably opened and closed.

  These containers are placed inside the main body or the like by placing objects in the main body or the main body part (hereinafter collectively referred to as “main body etc.”) and closing the lid or lid part (hereinafter referred to as “lid body etc.”). Houses things and is used for storage, transportation and exhibition.

  The main body and the lid and the like have fitting portions that fit together.

  The fitting part has various shapes, but a representative one is provided with a flange and drooping part (main body side fitting part) folded at the upper edge of the main body, etc. There is a thing which consists of the drooping part (lid body side fitting part) which covers the said main body side fitting part and engages elastically in the peripheral part.

  When closing the lid of the container having these fitting parts (main body side fitting part and lid body side fitting part), the main body side fitting part and the lid body side fitting part are aligned, and the lid side fitting part is By pushing down, the drooping portion of the lid-side fitting portion spreads and enters the body-side fitting portion, and when it enters a certain amount, it contracts elastically and engages with the body-side fitting portion. Thereafter, the hanging state of the lid body side fitting portion is elastically contracted around the body side fitting portion, so that the engagement state between the lid body and the main body is maintained.

  When opening the lid of the synthetic resin container having the fitting part, hook a nail or the like on a part of the edge of the lid side fitting part, widen the hanging part of the lid side fitting part, By removing the engagement, the lid or the like can be removed. Alternatively, the main body or the like is gripped to forcibly raise the lid body, and the engagement between the main body side fitting section and the lid body side fitting section is released against the elastic contraction force of the lid body side fitting section. The lid and the like can be removed.

  However, when opening the lid of the conventional synthetic resin container, it is necessary to apply a nail or the like to the edge of the lid-side fitting portion or forcibly pull up the lid, etc. It was difficult.

  On the other hand, Japanese Patent Application Laid-Open No. 2002-96851 describes a synthetic resin container that facilitates an operation of opening a lid.

  The synthetic resin container described in Japanese Patent Application Laid-Open No. 2002-96851 is provided with an opening / closing piece on each of the main body side fitting portion and the lid side fitting portion, and each opening / closing piece has a base end portion and a base end portion. A first engaging portion having a relatively small-diameter curved portion connected; a second engaging portion having a relatively large-diameter curved portion connected to the first engaging portion; and the second engagement. And an arm portion connected to the joint portion.

According to the synthetic resin container described in Japanese Patent Laid-Open No. 2002-96851, the first engagement portion and the second engagement portion of the opening / closing piece are rotated by rotating the arm portion of the opening / closing piece upward or downward. The joint can be disengaged.

  That is, in the above-described conventional synthetic resin container, when the lid is closed, if the large-diameter curved second engaging portion of the lid is pushed into the large-diameter curved second engaging portion of the main body, the lid is incidentally attached. The first engaging portion of the lid and the first engaging portion of the main body are engaged with each other, and the operation of closing the lid is completed. At that time, the engagement between the second engagement portions having the large-diameter curves is engaged in an adsorbing manner, but the first engagement portion having the small-diameter curve is engaged only incidentally.

  On the other hand, when opening the lid in the conventional synthetic resin container, it is difficult to remove the large-diameter curved second engaging portion of the lid from the large-diameter curved second engaging portion of the main body, When the second engaging portion with the large-diameter curve is removed, the first engaging portion with the small-diameter curve has already been released, and the first engaging portion with the small-diameter curve is disengaged. With little function.

  As described above, in the conventional synthetic resin container, the small-diameter curved first engaging portion acts only incidentally and does not perform the function of opening and closing.

  Therefore, the problem to be solved by the present invention is that when the main engagement is the engagement between the large-diameter curved second engaging portions, when the main engagement is in the engaged state, the engaged state A synthetic resin container having a sub-engagement function that facilitates disengagement of the main engagement when the main engagement is disengaged is provided.

  In other words, the problem to be solved by the present invention is to provide an opening / closing piece that engages with the main body and the lid, and the lid can be easily opened by operating one of the opening / closing pieces. An object of the present invention is to provide a synthetic resin fitting container which can be closed with a click-and-close feeling when closed.
