Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a cap for a container, particularly for shaking out a powder such as salt or chemical seasoning, or a fluid such as soy sauce filled in the container. It is.

[Prior Art] As one of the caps of so-called shaker containers filled with seasonings, etc., there is provided a stopper which has a portion for fixing to the container body at the lower part of the top wall through which an outlet is formed, and a top wall of the stopper. Container caps have been widely known, consisting of a lid that is rotatably hinged to one edge of a wall and covers an outlet. Items that can be published are presented in Publication Utility Model Publications No. 45-24360 and Publication No. 39267-50.

[Problems to be solved by the invention] However, the container cap proposed in the above-mentioned publication has a spring body interposed in the hinge between the lid and the inner stopper to maintain the closed and open states. However, since the spring body is constantly acting on the lid body, it must be rotated from fully closed to fully open against the biasing force of the spring body when opening and closing, which requires a large amount of force, resulting in extremely poor operability and poor structure. is complex,
Further, there is a problem that the contents may adhere to the spring body, causing malfunction or deterioration of the spring body.

Therefore, the object of the present invention is to simplify the structure and improve operability and durability of a cap for a container that allows the contents to be poured out with the lid fully open.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention includes a stopper having a portion for fixing to the container body at the lower part of the top wall through which the outlet is formed; In a container cap comprising a lid rotatably hinged to one edge of the top wall and covering the outlet, the lid has two vertically attached lids hanging from one edge of the lower surface of the container cap. A shaft installed between the legs is fitted into and held in an engagement groove opened on the upper surface of the top wall of the plug, and the plug is hinged to a wall located on the outside of the engagement groove. The upper end edge has a curved shoulder in which a passage groove for the leg body that is continuous with the engagement groove is formed, and the lid body is opened and closed at a position opposite to the axis on the lower surface thereof. At the same time, measures were taken to include a protrusion with a male which passes under pressure over said shoulder.

[Operation] When the lid is rotated from the closed position, the protrusion comes into pressure contact with the shoulder of the stopper between the closed position and the open position.
Due to the forced rotation, the protrusion is compressed and deformed and passes through. After passing through, it rotates again without resistance to the open position, and even if you tilt the container in that state or shake it upside down, the lid will move between the fully open position and the position where the protrusion hits the shoulder, but the lid will move further than that. Never closes. That is, the resistance only increases temporarily during opening and closing.

[Examples] Examples of the present invention will be described below based on the drawings.

The drawing shows an embodiment in which the present invention is applied to a container for dispensing granular materials.
a stopper 4 having an outlet 3 for filling the contents in the container body 2 formed therethrough; and a lid rotatably hinged to one end of the stopper 4 to cover the outlet 3. It is composed of a body 5.

To explain in more detail, the plug body 4 has a cylindrical cross-sectional shape, has a threaded groove-attached part 7 to the container body 2 at the lower part of the inner circumferential surface 6, and is made of glass material or hard synthetic resin material. Container body 2
It is fixed to the container body 2 by screwing into a screw thread 9 formed in the mouth part 8 of the container body 2. Further, a recess 11 is formed in the center of the upper surface 10a of the top wall 10 of the plug body 4, and a recess 11 is formed on both sides to open toward the outer periphery. Engagement grooves 12 open to the upper surface 10a for hingedly attaching the lid 5 are formed at the end edges. On the other hand, the lid body 5 has a shape that fits into the recess 11 of the plug body 4, and two leg bodies 17,
An engaging member 15 having a shape in which a shaft 14 is installed between the engagement members 17 is vertically provided, and an annular projection 16 that fits into the outlet 3 is protruded from the other side. The engaging member 15 is fitted into the engaging groove 12 and held therebetween, and the lid 5 is hinged to the stopper 4 so that the outlet 3 can be opened and closed. The lid 5 is fitted into the recess 11 of the plug 4, and the annular protrusion 15 is press-fitted into the outlet 3, fixing the lid 5 to the plug 4 and maintaining the closed state. There is. Furthermore, the lid body 5 is attached to the top wall 1 of the stopper body 4.
It opens almost at right angles to 0,
Therefore, the plug body 4 is attached to the upper end lid of the outer wall of the engagement groove 12 with legs 17 and 1 constituting the engagement member of the lid body 5.
The passage grooves 18, 18 of 7 form a curved shoulder 19 that is continuous with the engagement groove 12.
Furthermore, an elastic protrusion 20 is provided on the lower surface 13 of the lid 5 at a position opposite to the shaft 14 constituting the engagement member 15, and which passes through the shoulder 19 of the stopper 4 in a compressed deformed state when the lid 5 is opened and closed. It is installed protrudingly. Although the projection 20 is formed separately from the lid 5 in the illustrated embodiment, it is advantageous in terms of manufacturing if it is formed integrally with the lid 5.

Next, the state of use of this embodiment will be explained.

7 to 9 are enlarged partial cross-sectional views showing the hinged portion between the lid 5 and the plug 4. FIG.

FIG. 7 shows the closed state, in which the lid 5 is fitted into the recess 11 of the plug 4, the annular protrusion 16 is press-fitted into the outlet 3, and the lid 5 is fitted into the recess 11 of the plug 4.
is fixed and remains closed.

When it is desired to open the lid 5 and take out the contents, the end of the lid 5 opposite to the engaging member 15 is pushed upward, and the lid 5 rotates about the shaft 14. At this time, during rotation, the lower surface 13 of the lid 5
The protrusion 20 protruding from the stopper 4 comes into contact with the shoulder 19 of the stopper 4, but if it continues to be forcibly rotated, the protrusion 20 compresses and deforms the shoulder 19 and passes through, as shown in FIG. Then, as shown in FIG. 9, the top wall 10 of the plug body 4
Rotate until it is almost perpendicular to the Therefore,
In this state, the container body 2 is held and tilted or turned upside down, and the contents are shaken out from the open outlet 3. At this time, the protrusion 20 provided on the lower surface 13 of the lid body 5 is restored to its original state and comes into contact with the shoulder portion 19 of the plug body 4, thereby preventing the lid body 5 from rotating in the closing direction. Therefore, the lid 5 rotates between the fully open position and the position where the protrusion 20 hits the shoulder 19.
Since the open state shown in the figure is maintained, the lid 5 does not get in the way of taking out the contents. Also,
When the lid body 5 rotates, the contents are pushed into the protrusion 2.
Even if it adheres to 0, it falls immediately and does not accumulate.

When the contents have been removed, the lid 5 is rotated about the shaft 14 in the closing direction, and the lid 5 is returned to its original position in the order shown in FIGS. 8 and 7 in the opposite direction to the opening operation. Returns to closed state.

In this embodiment, the annular protrusion 16 is press-fitted into the outlet 3 and the lid 5 is fixed to the stopper 4 to maintain the closed state. As shown in , an engaging protrusion 5a is provided at the end of the lower surface of the lid 5, and an engaging protrusion 11a is provided on the upper surface of the recess 11 of the plug body 4 at a position slightly outside the engaging protrusion 5a. Other configurations may also be used, such as fixing the lid 5 to the stopper 4 by pressing and fitting these engaging protrusions 5a and 11a together.

[Effects of the invention] According to the invention having the above configuration, when the lid is opened during use, the elastic protrusion comes into pressure contact with the curved shoulder part during rotation, which only temporarily increases the resistance. Overall, it can be rotated with little force and has good operability. Furthermore, when the lid is opened, the container hits the shoulder and does not close any further, so the contents can be shaken out in a sufficiently open state. Furthermore, there is no spring body or place to install it, and only the shoulder of the stopper is curved and an elastic protrusion is provided on the bottom surface of the lid, so the structure is simple and there is no risk of malfunction due to adhesion of the contents. Not at all.
