Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a container with a lid that is elastically inverted. In addition, in this specification, a container and the like are used to mean both a cap and a container.

"Prior Art" Conventionally, many containers with lids that are elastically inverted are known, and a typical one is a so-called three-point hinge cap or container. The cap or container has a pair of left and right cap main bodies or container body upper ends and a rear lower end of a lid body placed on the upper surface of the cap body or container body, the mouths of which are opened on the upper surface of the cap body or the container body. First
In addition to being connected by a hinge, one end of the inverted L-shaped elastic plate provided between the first hinges is connected to the rear part of the cap body below the first hinge via the second hinge, and the other end of the elastic plate is connected to the front side of the first hinge. The upper surface of the lid is connected to each other via the third hinge.

[Problems to be solved by the invention] However, in the conventional containers and the like as described above, the lid opening angle at which the lid body is elastically inverted is relatively large (for example, about 45 °), so that the lid front There is a problem that the front part of the lid body cannot be pushed upward to a predetermined lid opening angle through a finger-hanging piece or the like protruding from the portion so that it cannot be performed with one hand as the container and the like become larger.

Therefore, an object of the present invention is to propose a container with a lid that is elastically inverted and can be used in a large size and is easy to use.

"Means for Solving the Problem" In order to solve the above problems, the container of the present invention has a cylindrical first shape.
A cylindrical body 1 having a peripheral wall 4 with an open upper surface, and a guide cylinder 8 vertically extending from a lower surface of a top plate 7 with a pouring hole 6 for closing the upper surface of the cylindrical body to rotate the guide cylinder to an inner surface of an upper portion of the first peripheral wall. A top plate member 2 fitted as much as possible and a second peripheral wall 12 extending vertically from the peripheral edge of the top wall 10 that closes the pouring hole, and the rear edge of the tubular body is elastically reversed by a three-point hinge. The top plate member 2 comprises a lid 3 connected via a mechanism 15, and a notch 13 having an opening in the lower end surface and having an inverted V shape is bored in either one of the left and right sides of the second peripheral wall. From the outer periphery of the top plate of the above notch 13
An inverted V-shaped rod-shaped connecting portion 9A that fits inside is projected, and a plate-like operation piece 9 is continuously provided outside the connecting portion 9A.

"Operation" For example, when the operation piece 9 is rotated counterclockwise with respect to the tubular body 1 from the state shown in FIGS. 1 and 2, the rear surface of the connecting portion 9A slides back on the rear surface of the notch 13 so as to retreat. , The lid 3 is pushed up by the action of the “wedge”, so that the rod-shaped plug 11 requiring a relatively large force can be easily detached from the pouring hole 6. Then, when the operation piece 9 is still further rotated, the connecting portion 9A moves rearward between the lower surface of the lid peripheral wall 12 and the upper surface of the cylindrical body 1, and opens the lid 3 to the opening angle at which the lid 3 is elastically inverted backward. Due to the action of the elastic plate 1, the lid is opened as shown in FIG.

[Embodiment] An embodiment of a container with a lid that is elastically inverted according to the present invention will be described below with reference to the accompanying drawings.

1 to 3 show an example in which the present invention is applied to a cap.
It is formed of a cylinder body 1, a top plate member 2, and a lid body 3.

The cylindrical body 1 has a cylindrical first peripheral wall 4 and has an open upper surface. The cylindrical body 1 is adapted to be screwed into a not-shown container neck portion by a screw thread 5 attached to the inner surface of the first peripheral wall 4.

The top plate member 2 is a pouring hole 6 that closes the upper surface of the cylindrical body 1 described above.
A guide cylinder 8 is vertically provided from the lower surface of the attached top plate 7
Is rotatably fitted to the upper inner surface of the first peripheral wall 4 described above. An operating piece 9 is projected from the outer peripheral portion of the top plate 7 to the outside of the cylinder body 1 via a connecting portion 9A having an inverted V-bar shape. The upper surfaces of the operation piece 9 and the connecting portion 9A are formed as an inclined surface 9a in the rearward and downward direction.

The lid 3 detachably fits the rod-shaped plug 11 that hangs from the lower surface of the top wall 10 that covers the upper surface of the top plate 7 described above into the pouring hole 6 that is described above, and the second peripheral wall that vertically extends from the peripheral edge of the top wall 10. 12 The lower part is fitted to the outer surface of the top plate 7 described above, and the second peripheral wall 12
An inverted V-shaped notch 13 having an open lower end is formed on the right side of the. Then, the operation piece 9 described above is provided in the notch 13.
The connecting portion 9A of is fitted. The rear side surface of the notch 13 is a front upper sloped surface 13a corresponding to the above-described sloped surface 9a.
With these two inclined surfaces 9a and 13a, the lid body 3 is pushed up by the rotation of the top plate member 2 with respect to the cylindrical body 1 described above, and the lid body 3 is opened by the elastic reversing mechanism portion 15 described later. It is configured to open up to the opening angle that elastically reverses to.

The elastic reversing mechanism portion 15 is formed by connecting the rear edge portion of the cylindrical body 1 and the rear edge portion of the lid body 3 described above with a three-point hinge.
The three-point hinge means a pair of left and right thin first hinges 16 forming a pair of left and right with an appropriate interval between the upper end of the rear surface of the first peripheral wall 4 of the tubular body 1 and the lower end of the rear surface of the second peripheral wall 12 of the lid 3. , 16 and the one end of the inverted L-shaped elastic plate 17 provided between the first hinges 16 and 16 is connected to the first peripheral wall 4 portion below the first hinges 16 and 16 via the thin second hinge 18. In addition, the other end of the elastic plate 17 is connected to the top wall 10 of the first hinges 16 and 16 in front of the first hinges 16 via a thin third hinge 19.

Further, in the above-mentioned embodiment, each part is appropriately formed by molding synthetic resin.

[Advantage of Invention] As described above, according to the present invention, the lid can be elastically inverted to the open side by the horizontal rotation operation of the operation piece, so that even if the container is enlarged, it can be easily opened with one hand. It can be covered, which makes it convenient to use.
