The cover can be easily opened by pressing the cover from both sides to deform the cover 4.

Since the container of the present embodiment has the above-described configuration, the fitting state between the lid 4 and the container body neck 3 is extremely strong, and even when the container is dropped sideways, the lid is closed. Is hard to come off. For example, when a drop test in which the container shown in FIG. 1 is filled with water and dropped laterally from a height of 1 m was performed five times, the lid 4 never came off the container body.

Further, according to the container of the present embodiment, the fitting state between the lid 4 and the container body neck 3 can be easily released by slightly rotating or deforming the lid 4.
Unlike the screw type, there is no need to rotate the lid several times, and the lid opening operation is extremely simple.

According to the container of the present embodiment, the lid 4
Is in contact with the inner peripheral surface of the lid 4 (side wall surface 71) and not in contact with the inner peripheral surface of the lid 4 (corner surface 70) when fitted to the neck.
Since the lid 3 is provided on the neck 3, the lid 4 can be rotated extremely smoothly, and the fitted state between the horizontal ribs 5 and the horizontal grooves 6 can be released very easily. Further, since no horizontal groove or the like is formed in the corner surface 70, the lid 4 after the engagement between the horizontal ribs 5 and the horizontal groove 6 is released can be pulled upward with extremely light force. .

Further, according to the container of the present embodiment, the stepped portion 72 is provided at the base end of the corner surface 70, and the opening lower end portion 42 of the lid 4 generated by rotating the lid 4. Is adapted to assist the detachment of the lid 4 from the container body 2 by utilizing the force when climbing on the stepped portion. Can be detached from the neck 3 of the camera. Therefore, the container body 2
Is not forcibly opened, so that the contents are prevented from jumping out when the lid is opened.

Further, the lid 4 in the container of the present embodiment.
Can be used as a measuring container for powder or the like in the container main body 2, but since the lid 4 has a rectangular cross section having a flat corner having an arc-shaped corner as shown in FIG. Even if an excessive amount of content is put in the lid 4, the excess can be easily returned into the container body 2 via the corner. Therefore, the user can perform weighing without worrying about excessive weighing, and can also perform strict weighing while repeating insertion and return.
From such a viewpoint, it is preferable that the radius of curvature R (see FIG. 3) of the arc-shaped corner is smaller than the radius r of the spout 1.

Further, according to the container of the present embodiment, the inner ring 42 is formed on the top surface portion 40,
Since the inner ring 42 is fitted into the spout 1, the spout 1 is sealed, and the powders, liquids, and the like contained in the container body 2 are filled with the inner ring 42. Leakage from the mouth 1 is effectively prevented. Note that, instead of the inner ring 42, an outer ring 43 as shown by a dotted line in FIG. 2 may be provided. Even if such an outer ring is provided so as to contact the outer peripheral surface of the spout 1, the same effect as that of the inner ring can be obtained.

According to the container of the present embodiment, the lid 4
A plurality of levels of horizontal ribs 5 are formed on the inner peripheral surface of the container body 2 and these can be used as scales for measurement, so that it is easy to measure powders, liquids, and the like stored in the container body 2. Furthermore, since the horizontal ribs 5a and 5b of the plurality of stages are formed at a position closer to the lower end 42 of the opening than the center in the depth direction of the lid 4, the horizontal ribs 5a and 5b are scaled for measurement. Can be used effectively. When the horizontal ribs 5a and 5b are used as scales for measurement, it is preferable that the cover 4 is transparent or translucent so that the positions of the horizontal ribs 5a and 5b can be confirmed from outside.

As the material for forming the lid 4 in the container of the present embodiment, various kinds of generally known synthetic resins can be used, and from the viewpoints of easiness of elastic deformation, sealing, and opening and closing work. Polyolefins such as polypropylene and polyethylene, particularly polypropylene, can be preferably used. Further, as a material for forming the container body 2, various kinds of generally known synthetic resins and glass can be used. The method for manufacturing the lid 4 and the container body 2 is not particularly limited, and can be manufactured by various known methods.

For example, instead of providing a plurality of levels of horizontal ribs 5 on the lid 4 side and providing a horizontal groove 6 to be fitted to the horizontal rib 5 on the lid body 4 side on the container body 2 side, the inner periphery of the lid body may be provided. A plurality of horizontal grooves may be provided on the surface, and horizontal ribs fitted into the horizontal grooves may be provided on the outer peripheral surface of the container body 2. In this case, the same effects as those of the container of the above embodiment can be obtained.

In the container of the above embodiment, upper and lower horizontal ribs 5a and 5b are provided on the inner peripheral surface of the lid 4, and upper and lower horizontal grooves 6a and 6b are provided on the outer peripheral surface of the neck portion 3.
However, the horizontal ribs and the horizontal grooves may be provided in three or four steps. Further, only one set of a plurality of horizontal ribs 5 may be provided at opposing positions on the inner peripheral surface of the lid 4.

The shape of the lid 4 may be an elliptical flat cross section as shown in FIG.
As shown in (b), the cross section may be substantially square in plan.
Also in this case, it is easy to return the excess weighed amount into the container body 2, and from this viewpoint, the minimum radius of curvature of the elliptical shape is preferably smaller than the radius of the spout 1 of the container body 2. Even in the case of a substantially square cross section, it is preferable to have an arc-shaped corner having a radius of curvature smaller than the radius of the spout 1.

Further, the horizontal rib and the horizontal groove are set to appropriate values such that the length in the width direction and the protruding height can be fitted to each other, and the fitting is released by rotation or deformation of the lid. can do. Further, the horizontal ribs and horizontal grooves may have the same or different horizontal length, height, and depth in the upper stage and the lower stage, respectively. In addition, the form of the horizontal rib can be appropriately selected as the form of the fitting rib of this type of product, such as tapering, in order to make the fitting easy and strong. The shape of the spout 1 may be a square, a triangle, an ellipse, or the like, in addition to a circle. Regarding the shape and dimensions of other parts of the container of the present invention,
