Description

[Detailed description of the invention] [Industrial field of application] The present application does not use an elastic member such as a spring on a lid plate provided on a rectangular main body with an open top, but instead uses a part of the main body as a hinge part instead of an elastic member. By integrally molding the rectangular main body with an open upper part and the cover plate, the main body and cover plate are made of flexible material without using parts such as bearings, shafts, and elastic members (springs). It has a hinge part that has a certain elasticity and can be opened and closed reliably, and has a hinge part between the lid body and the side wall connected thereto, so that the connecting part and the corner part of the hinge part can be used for durability. This is an idea related to a connecting structure.

[Conventional technology]

Conventionally, as shown in Japanese Utility Model Publication No. 49-26033,
Some containers have a bent plate that is sandwiched between the cut lines, but since the bent plate is a single piece of plate and has no grooves, the thin joints at both ends of the bent plate and the bent line connecting the lid and the container body are easily damaged due to stress.

[Problem that the invention attempts to solve]

The present invention is an attempt to solve the problem that since there is no groove in the member that gives elasticity to the hinge, a load is placed on the joint between the container body and the lid, causing it to break easily.

[Means for solving problems]

In the present application, a groove portion in the shape of a character perpendicular to the slit surrounded by two slits is formed horizontally toward the inside of the main body, and a certain amount of opening/closing force is applied to the groove portion, and a line connecting the mutual ends of the two slits is formed. This invention solves the problem by forming right-angled triangular grooves horizontally on the back surface of the screen, creating a spring effect between the grooves, and reducing the load exerted on the corners by the grooves.

[Effect]

When the lid plate is rotated relative to the main body to open and close, an arc drawn with the length of the connecting part of the rear side plate and the connecting part of the lid plate as a fulcrum and the connecting part of the rear side plate as a fulcrum, and a corner of the lid plate are drawn. A crescent-shaped part formed by an arc drawn with the length of the connecting part as a radius and the corner part as a fulcrum acts as a spring effect to open and close the lid body 2 with respect to the main body 1, and also a parallel member forming a letter-shaped groove part. By opening and closing the spacing slightly around the connecting portion, a flexible elasticity is generated and the load on the connecting portion and the corner portion is reduced, thereby preventing the connecting portion and the corner portion from being cut.

Embodiment Now, to explain the embodiment, a main body 1 with an open top of a rectangular container or a cap is formed, and the main body 1 is
Two parallel slits 3 are cut across the top of the lid plate 2, which is openable and closable, and the rear side plate 1a of the main body 1, which is connected at right angles to the lid plate 2. A letter-shaped groove portion 4 for imparting elasticity to either or both of the side plate 1a, the lid plate 2, and the rear side plate 1a is formed horizontally toward the inside of the main body 1, and the ends of two parallel slits 3 are provided. A right triangular groove 6 is carved horizontally on the inner surface of the lid plate 2 and the rear side plate 1a at the location of the line 5 connecting the lid plate 2 and the rear side plate 1a, and a connecting part 7 at the top of the right triangle connects the lid plate 2 and the rear side plate 1a. The hinge portion B is formed by forming the hinge portion B by using the corner portion 8 which is formed as a hinge.

In the case of FIGS. 1 to 4, the groove 4 is the slit 3.
The slit 3 is formed on the rear side plate 1a sandwiched between the slits 3 at right angles to the slit 3 and at about the midpoint between the top and bottom heights of the slit 3 and horizontally toward the inside of the main body 1.

In the case of FIGS. 5 to 7, in addition to forming a groove 4 in the rear side plate 1a, a groove 4 is formed in the cover plate 2 at a right angle to the slit 3 and in a portion other than the area sandwiched between the two slits 3. A groove portion 4 is formed toward the inside of the main body 1 at the middle of the length.

In the case of FIG. 8, the structure is the same as that of FIGS. 1 to 4, but the lengths of the slits 3 provided in the cover plate 2 and the rear side plate 1a are different. In this case, the groove portion 4 is formed so as to be inclined downward from the corner portion 8 of the rear side plate 1a toward the inside of the main body 1.

In the case of FIG. 9, it is a cap, and unlike the container A of FIGS. 1 to 8, the connecting part 7 of the rear side plate 1a
A partition plate 9 is provided horizontally at the lower part of the side plate 9, and the side plates 1b other than the rear side plate 1a are cut vertically with the partition plate 9.
The bottom plate is removed, and a spout barrel 10 is installed in the center of the partition plate 9 facing upward, and the inside of the spout barrel 10 is placed at a location where the spout barrel 10 matches when the lid plate 2 is closed on the back side of the lid plate 2. A cap C is formed by providing a protrusion 11 that fits in the hole, and the cap C is used by fitting into the mouth of another container.

In the present application, when the lid plate 2 is rotated relative to the main body 1 to open and close with the above-mentioned configuration, the length of the connecting portion 7 of the rear side plate 1a and the connecting portion 7 of the lid plate 2 is set as a radius R, and the rear side plate 1a is connected. A crescent-shaped portion Z formed by a circular arc X drawn using the portion 7 as a fulcrum and an arc Y drawn using the corner portion 8 as a fulcrum with radius r being the length of the corner portion 8 and the connecting portion 7 of the cover plate 2 is a spring. The effect is that the lid body 2 is against the body 1.
It opens and closes.

Further, by slightly opening and closing the interval 1 between the parallel members 4a forming the letter-shaped groove 4 around the connecting portion 4b, a flexible elasticity is generated, and the connecting portion 7 and the corner portion 8
By reducing the load applied to the connecting portion 7 and the corner portion 8, it is possible to prevent the connecting portion 7 and the corner portion 8 from being cut.

Although the figure shows a cube, it may be a cylinder, a square cylinder, or a polygon. However, the connecting part 7 and the corner part 8 only need to be straight lines, and the hinge part B formed in this way should be in one place. However, it may be formed in two places or in multiple places depending on the length.

Effect A main body of a rectangular container or cap with an open top is formed, and a lid plate provided on the top of the main body that can be freely opened and closed, and two parallel walls connected to the rear side plate of the main body connected at right angles to the lid plate. A book slit is cut into the book, and a letter-shaped groove is formed horizontally between the two slits to give elasticity to the rear side plate, facing toward the inside of the main body, approximately midway between the two slits, and on the cover plate and the rear side plate. A right-angled triangular groove is carved horizontally on the inner surface of the lid plate and the rear side plate at the point where the line connects the ends of the two parallel slits, and at the connecting part of the top of the right triangle and between the lid plate and the rear side plate. Since the hinge part is formed by connecting the corner parts of By integrally molding the main body of the container or cap and the lid, the main body and the lid have elasticity centered around the integrally molded hinge part without using parts such as bearings, shafts, and elastic members. It can be opened and closed reliably, and furthermore, by opening and closing the parallel members that form the letter-shaped grooves with a slight spacing around the connecting portion, flexible elasticity is created, reducing the burden on the connecting portions and corners. This has the effect of preventing the joints and corners from being cut.
