Description

  The present invention relates to a container with a hinge lid, and in particular, has a lid that is openably and closably connected to a peripheral edge of a main body portion through a thin hinge portion, and a nozzle opening formed in a central portion of the main body portion is located inside the lid The present invention relates to a container with a hinge lid that is sealed by a protruding bar-shaped protrusion.

  The hinged lid is connected to the top edge of the main body by the container body closed at the top and the top edge of the main body by the cap attached to the top of the container body so that it can be opened and closed via a thin hinge. The nozzle opening formed in the main body can be opened or sealed by, for example, a rod-shaped protrusion protruding inward from the lid while opening and closing the lid. Yes. The thin hinge part of the container with a hinge lid is generally configured by a belt-like part that can be folded in two because the center is thin (see, for example, Patent Document 1).

On the other hand, in a container with a hinge lid that opens and closes the nozzle opening formed in the main body by a rod-shaped protrusion protruding inward from the lid, the nozzle opening is sealed by inserting the rod-shaped protrusion, for example, when dropped When the impact is applied, the lid is displaced relative to the main body, which causes a sudden bending load to be applied to the rod-shaped projection that sealed the nozzle opening, resulting in a rod shape such as pin breakage. Protrusion may be damaged. For this reason, for example, by attaching an O-ring made of an elastic member to the peripheral edge of the opening of the nozzle opening and engaging the rod-shaped projection, the nozzle opening is sealed by the rod-shaped projection while absorbing the impact when dropped. Containers with hinged lids are also known.

  The thin-walled hinge portion 15 that connects the main body portion 13 and the lid 14 of the cap 12 is known as a thin-walled hinge portion, and as shown in FIG. It is constituted by a pair of possible belt-like portions 25. The thin hinge 15 is disposed between the pair of parallel strips 25 and is elastic as an urging means for urging the main body 13 to open or close the lid 14. A piece 24 is provided, which is a so-called bellows hinge type hinge.

  In the present embodiment, the top plate 13a of the main body portion 13 is further provided with an engagement hole 19 disposed between the connecting portion 18 of the thin hinge portion 15 and the nozzle opening 16 at the periphery. A rod-like auxiliary projection 20 that engages with the joint hole 19 is provided so as to protrude inside the lid 14. The engaging hole 19 and the rod-like auxiliary projection 20 are simply incorporated as a constituent part of the cap 12 when molding the cap 12 integrally as a synthetic resin molded product with the lid 14 open to the main body 13. And it can provide easily. In addition, the engagement hole 19 is a position where the liquid detergent is not leaked from the engagement hole 19 when the liquid detergent accommodated through the nozzle opening 16 is poured out, and is thinner than the nozzle opening 16. It arrange | positions between the nozzle opening 16 which approached the side, and the connection part 18, for example, is formed in circular shape.
