Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to an annular mouth frame that is freely placed on the top opening of a transportation container or the like and is used to increase the internal volume.

Purpose The purpose of the present invention is to reliably prevent the opening frame from moving laterally with respect to the container when it is installed, and to prevent the opening frame from moving in the lateral direction even when stacked in multiple stages. An object of the present invention is to provide a new mouth frame for increasing the internal volume of a container.

DESCRIPTION OF THE INVENTION In order to achieve this object, the present invention has a structure in which a restriction member is formed protruding from the circumferential wall of the mouth frame to fit into the frontage of the main container.

EXAMPLE Hereinafter, an example in which the present invention is embodied in a mouth frame for increasing the internal volume of a transportation container will be described with reference to FIGS. 1 to 4.

The mouth frame 1 of this embodiment is formed into a square annular shape by synthetic Q4 resin corresponding to the upper opening 2a of the square box-shaped main container 2, and has flange parts 3 and 4 on the upper and lower ends thereof, respectively. A plurality of reinforcing ribs 5 are provided on the outer surface of the peripheral wall so as to extend vertically between the two flange portions 3.4. By placing the opening frame 1 on the upper surface of the main container 2, the internal volume of the main container 2 is increased by the internal volume of the opening frame 1.

As shown in FIG. 2 and FIG. 5 predetermined gaps 7 are cut out between the end faces of each regulating piece 6. When the mouth frame 1 is attached to the main container 2, the regulating piece 6 is inserted into the opening 2a of the main container 2. By being fitted and joined to the inner surface of the peripheral wall, [1
The frame 1 is positioned 4j with respect to the main container 2.

On the other hand, as shown in FIG. 1, FIG. 2, and FIG. Connectors 9 made of synthetic resin are each rotatably attached. The Pr trace 9 has a planar cross-shaped upper side 1o with a recess 'IOa formed on the upper surface, a vertical part '11, a lower side 12, and the vertical part 11.
The finger rest protruding from the lower surface of the mouth frame 1 is composed of a protrusion 13.
When the frame 1 is attached, the lower flange 4 of the frame 1 and the L flange 2b of the main container 2 are connected to the upper side 1o and the lower side 12.
(The attached state of both is maintained, and the finger hook pulls the protrusion 13 outwardly (when the lower side part 12 leaves the lower end of the flange part 2b, The 116th effect of roughly pulling the finger hook projection 13 outward and rotating the connector 9 approximately 901 times is that both the flange portions 4,
2b is released from between the upper side 1o and the lower side '12.

Now, there is one point in this embodiment configured as described above.
] J-3 (IJ) is formed on the first frame for increasing the inner volume, and regulating pieces 6 are formed on each of the four sides of the frame. ) is positioned while reliably preventing movement in the lateral direction relative to the main container 2. Therefore, even if a plurality of opening frames 1 are stacked on the top surface of the main container 2, as shown by the chain lines in FIG. The internal volume of the container 2 can be increased to a desired size and the space can be used effectively.

In addition, in the mouth frame 1 of this embodiment, gaps 7 are formed at four corners of the regulating halo, so that
If the regulating piece 6 is curved and deformed during the molding process of the mouth frame 1, the regulating piece 6 may not be able to be fitted into the 17i1 bottom portion 2a of the container body 2, or the mouth frame 1 may wobble when attached. There is no fear. However, generally speaking, if such a thin regulating piece 6 is continuously formed in an annular shape without providing a notch 7, distortion will occur in various places due to shrinkage as the regulating piece 6 cools after molding. There is an inconvenience that the surface is undulated and deformed into a curve. Therefore, conventional methods 1. :
In this case, insert a jig inside the regulating piece 6 to prevent deformation.
It was necessary to take measures against this problem through KM. However, if a gap 7 is formed at each corner of the sea urchin regulating piece 6 of the mouth frame 1 of this embodiment, it is possible to prevent the curved deformation during the molding process without using a special jig. Can be done.

Furthermore, in this embodiment, since the connectors 9 are attached to four locations around the mouth frame 1 in J'3, each connector 9 can be rotated to the side where the mouth frame 1 is mounted. part 10 and T side part 12
between the lower flange part 4 of the mouth frame '1 and the main container 2.
By grasping the partial flange portion 21), the mouth frame 1 and the main container 2 are firmly connected, and there is no fear that they will be separated during transportation 11JI. However, by doing so, the collapsing of the spout frame 1 can be reliably prevented, especially when a large number of spout frames 1 are stacked on the main body container 2.

Another Embodiment The present invention is not limited to the structure of the above-mentioned embodiment, but can also be embodied in other embodiments described in the next section.

(1) As illustrated in FIG.
No.6, 4322, each has a gap 17 cut out in the center.

(2) Not shown in FIG. 6: One narrow regulating piece is formed protruding from the center of each of the four sides of the lower end of the mouth frame 1.

(3) As shown in FIG. 7, key-shaped regulating pieces 2'1 are formed protruding from each of the four corners of the inner periphery of the lower end of the mouth frame 1.

(4) As shown in FIG. 8, a band-shaped restriction part 23 is formed protruding from each of the two sides of the inner circumferential edge of the lower part Q1 of the mouth frame '1.

5) Shape the mouth frame 1 into a regular square ring, a circular ring, or a polygonal ring according to the shape of the main container for various uses.

Effects As described in detail above, this invention has a restricting piece that fits into the opening of the main container protrudingly formed on the lower surface of the peripheral wall of the mouth frame, thereby making it easier to attach the mouth frame in the lateral direction. It is possible to reliably prevent movement, and even when stacked in multiple stages, there is no risk of one of the frames falling over, which is an excellent effect.
