Description

  The present invention relates to a container with a lid such as a cosmetic, and more particularly to a container with a lid whose outer peripheral wall is a non-round shape such as a quadrangle, a polygon or an ellipse in plan view.

2. Description of the Related Art Conventionally, many lidded containers whose outer peripheral wall is a non-round shape such as a quadrangle, polygon, or ellipse are used as containers for cosmetic skin cream, for example.
In such a container with a lid, the lid body is screw-engaged with the mouth portion of the container body. However, since the container has a square shape, the lid body and the container body are aligned when the lid body is tightened. It is necessary to perform positioning.

Many positioning structures for the lid have been proposed, but it is general that the container main body is provided with an engaging projection for positioning the completion of tightening by getting over when the lid is tightened.
Specifically, as shown in FIG. 3, the engagement protrusion 11 is provided on the shoulder of the container body 10, and the vertical rib 13 is extended from the lid 12 side, and this has been lowered by tightening the screw. The vertical ribs 13 of the lid body 12 are pressed against the engaging protrusions 11 of the container body 10, and the fastening completion positioning is performed by getting over the engaging protrusions 11.

However, in such a conventional container with a lid, the engagement protrusion 11 formed of a synthetic resin and the vertical rib 13 are moved over by pressing, so that when the container is repeatedly opened and closed, the engagement protrusion 11 And the vertical ribs 13 are likely to be worn out.
In order to increase the durability of the engaging protrusions 11 and the vertical ribs 13, it is conceivable that the engaging protrusions 11 and the vertical ribs 13 are formed to be large. Sinking occurs on the top plate of the body 12.
Moreover, when the engagement protrusion 11 is enlarged in the radial outward direction, the short diameter portion 14a of the outer peripheral wall 14 of the lid 12 interferes as shown in FIGS.
Furthermore, when the engagement protrusion 11 is formed high, the vertical rib 13 of the lid 12 comes into contact with the engagement protrusion 11 at a position opposite to 180 ° before reaching the original position due to the screw pitch. A problem occurs.

  In view of the problems of the above conventional lidded container, the present invention suppresses the wear of the engaging projections and omits the conventional vertical ribs to prevent the occurrence of sink marks on the lid top plate. An object of the present invention is to provide a container with a lid in which the run torque is increased to increase the positioning and fixing force of the lid.

  In order to achieve the above object, a container with a lid of the present invention comprises a container body and a lid body whose outer peripheral wall is non-circular, and screw-engage the lid body to the mouth of the container body, In a container with a lid provided with an engagement projection that positions the completion of tightening by overriding when the lid is tightened, it can swing flexibly from the periphery of the base of the mouth of the container body to the outer peripheral wall side The flange portion is extended, and an engagement protrusion is provided on the surface of the long diameter portion of the flange portion so as to be fitted into the long diameter portion of the outer peripheral wall when the outer peripheral wall of the lid body gets over. .

  In this case, the engagement protrusion can be formed in a mountain shape having an inclined portion in the rotation direction of the lid.

According to the container with a lid of the present invention, the container body includes a container body and a cover body whose outer peripheral wall is a non-circular shape, and the lid body is screw-engaged with the mouth of the container body, and the lid body is fastened to the container body. In a container with a lid provided with an engagement protrusion that positions the completion of tightening by overcoming, a flexible, swingable flange is extended from the periphery of the mouth of the container body to the outer peripheral wall. In addition, an engagement protrusion that fits into the long diameter portion of the outer peripheral wall is provided on the surface of the long diameter portion of the flange portion when the outer peripheral wall of the lid rides over the surface of the flange portion. In the case of overcoming, the resistance of the press contact is reduced by bending the flange portion downward, and the wear of the engaging protrusion and the outer peripheral wall of the lid can be suppressed.
In addition, since the outer peripheral wall of the lid is used to get over the engaging protrusion, the conventional vertical rib is omitted to prevent the cover top plate from sinking, and overcoming the engaging protrusion By using the wall, the overrun torque can be strengthened and the positioning fixing force of the lid can be increased compared to the structure near the inner periphery where the engagement protrusions are provided around the mouth.

  In addition, by forming the engaging protrusion in a mountain shape having an inclined portion in the rotation direction of the lid, the inclined portion guides the outer peripheral wall of the lid so that the engagement protrusion can be easily climbed over. Opening and closing can be performed smoothly.
