Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a cap used for, for example, a container for dispensing seasonings and the like.

(Prior Art) A conventional cap of this type, in which a cap body is combined with a lid piece that bends in the middle, and the drawing hole is opened and closed by the bending of the lid piece, is disclosed in, for example, Japanese Utility Model Application No. 56-62956. Already published.

(Problems to be solved by the invention) With the above-mentioned conventional method, there is a concern that the lid piece is bent in the middle and the bent lid piece is held in that state when the dispense hole is opened. During dispensing, the lid piece inadvertently fell down, blocking the dispensing hole and causing the contents to be scattered around.

(Means for Solving the Problems) The present invention eliminates the above-mentioned conventional disadvantages, and in a device that opens and closes the dispensing hole by refraction of the lid, securely maintains the upright and open posture of the lid in the open state due to refraction, and A frictional engagement part is formed between the cap body and the cap body to hold it more accurately, and also to open it.
The purpose is to give moderation to the switching of the closing operation, improve the operating feeling, and make the operation smoother.
A lid in which a concave portion is formed on one side of the top surface of the cylindrical cap body by a vertical partition wall and a bottom wall, and a bending portion with a recessed groove is provided in the middle so that the front and rear halves are continuous and bendable. The rear end of the lid piece is rotatably connected to the cap body within the groove, and by bending and stretching the lid piece at the bent part, the opening hole opened in the top surface of the cap body can be opened and closed using the front half of the lid piece. When the lid piece is bent and opened, the front half of the lid piece stands up along the outside of the partition wall, and its lower end touches the partition wall with a straight part of the minimum length within the required range, and is bent. is controlled to be positioned below a line connecting the center of the rotating part of the rear end of the lid piece and the upper end of the straight part,
Furthermore, a plate-shaped protrusion was provided on either one of the lower surface of the rear half of the lid piece and the upper surface of the bottom wall of the recess, and a pair of plate-shaped pieces were provided on the other side with an interval such that a pair of plate-shaped pieces could be press-fitted into the protrusion. The projecting part and the receiving part are fitted into each other and frictionally engaged, and when the lid is extended and the lid is closed, the bent part of the lid is positioned above the line and the protruding part and the receiving part are separated. It is characterized by what it did.

(Function) In the present invention, as shown in FIG. 1 of the embodiment, when the drawing hole 7 of the front half 5a of the lid piece 5 is closed, if the rear half 5b of the lid piece 5 is pushed with a finger, the lower part of the folded part 6 As a result of the movement, the cover piece 5 bends as shown in the third figure to open the swinging hole 7. At this time, the front half 5 of the lid piece 5
a stands up along the outside of the partition wall 3 to stabilize the open state, but the lower end of the front half 5a meets the partition wall 3 in a straight section 8 spanning the minimum length l within the necessary range to stabilize the upright state. At the same time, the bent portion 6 of the lid piece 5 is also positioned below the dead line a at a distance l' approximately equal to l when the opening/closing switching operation is performed, so that the open state of the lid piece 5 is ensured. In addition, the switching operation from opening to closing is made easier by moving the bent portion 6 by l', and when opening, the plate-shaped protrusion 11 moves between the pair of plate-shaped pieces 12a,
12a, the opening position of the lid piece 5 can be further stabilized by frictional engagement with the receiving part 12. Switching between opening and closing and closing and opening can be done by using the bent part 6 of the lid piece 5. Since the switching operation is carried out beyond the dead line a, it gives a sense of moderation to the hands and fingers during the switching operation.

(Example) Embodiments of the present invention will be described with reference to the drawings.

As shown in Figs. 1 to 4, the cap of the present invention has a cylindrical cap body 1 made of synthetic resin.
and a lid piece 5, and a recess 2 is formed on one side of the top surface of the cap body 1 by a vertical partition wall 3 and a bottom wall 4.

The lid piece 5 has a thin bent part 6 formed by a recessed groove in the middle, and the front and rear halves 5a and 5b are continuous into an integral plate shape, and the rear end of the lid piece 5 is connected to the cap body 1.
are rotatably coupled on the concave portion 2 side. That is, small protrusions 13, 13 are protruded from the upper part of the side wall of the recess 2, and the recessed holes 14, 14 provided in the sleeve pieces 15, 15 on both sides of the lid piece 5 are pushed into the protrusions 13, 13, so that the small protrusions 13 and the recess are inserted. The inlet hole 14 was fitted to form a shaft support. A plate-shaped protrusion 11 is provided on the lower surface of the rear half 5b of the lid piece 5, and a pair of plate-shaped pieces 12a are provided on the upper surface of the bottom wall 4 of the recess 2.
12a are protruded at intervals to form a receiving part 12 into which the protrusion 11 is press-fitted.

In the above configuration, as shown in FIG.
When the rear half 5b is pressed down with a finger, the lid piece 6 is bent by the downward movement of the bent part, and the swinging hole 7 is opened by the front half 5a.
In this case, it is necessary for the lower end of the front half 5a of the lid piece to contact the outer surface of the partition wall 3 at the straight line part 8, but the length l of the straight line part 8 in contact with the outer surface of the partition wall 3 is
If the lid is short or small, it becomes impossible to stabilize the lid in an upright position, and when the length l of the contacting straight part is lengthened to ensure that the lid is in an upright position, the frictional resistance of the contact surface increases. As will be described later, the operation of switching the lid piece 5 from the open state to the closed state becomes impossible or extremely unsmooth.

That is, when the lid piece 5 is opened by bending, the front half 5a of the lid piece 5 is kept in an upright state by contacting the outer surface of the partition wall 3 with a straight part 8 extending over a length of l, as shown in FIG. At this time, the bending part 6 is controlled to stop at a lower position with respect to a line a connecting the rotation center 9 of the lid piece 5 and the upper end 10 of the straight part 8, so that the upper and lower parts of the bending part 6 are In movement, moderation is provided by switching operation that exceeds line a.

Furthermore, at the position of the bent portion 6 shown in FIG. 8, the moving length l' required for the bent portion 6 to cross the line a has almost the same relationship as the length l of the contact straight portion 8. , as shown in the figure, the front half 5a of the lid piece is in an upright state.
When pressing in the direction of the arrow to close the
The shorter l' is, the easier the switching operation from open to closed is, and the longer l' is, the longer l is, which increases the contact friction with the partition wall 3, causing inconvenience in the switching operation from open to closed. For this reason, the contact length l between the partition wall 3 and the lower part of the front half of the lid 5a is set to the minimum length l within the range that ensures that the lid piece 5 is maintained upright in the open state, so that the switching operation to close can be smoothly performed. For example, generally the contact length l is suitably within 5 mm.

In addition, when the upper end corner edge of the partition wall 3 has an R as illustrated in FIG. 8, the starting point of the R is the upper end 10 of the straight portion 8. In addition, although the outside of the partition wall 3 is shown to be vertical in the same figure, it is not necessarily limited to being vertical, and the same effect can be achieved by using an inclined surface that is tilted inwardly and outwardly.

Furthermore, when the lid piece 5 is bent to open, the plate-like protrusion 11 provided on the lower surface of the rear half 5b is inserted into the receiving part 12.
The lid piece 5 is elastically press-fitted between the pair of plate-like pieces 12a, 12a constituting the lid, and its frictional resistance further ensures the open state of the lid piece 5. When switching to the closed position, the lid piece 5 is folded as described above. Moderate operation is performed by the feeling when the curved portion 6 crosses the line a and the feeling of separation of the protrusion 11 and the receiving portion 12.

Although the pair of plate-shaped pieces 12a forming the receiving part 12 also serve as a control member for the downward movement position of the bending part 6 when the lid piece 5 is bent during the opening operation, the control member may be provided separately. .

In the figure, reference numeral 16 denotes a stopper protruding from the lower surface of the rear half 5b of the lid piece 5, and the stopper 16 is attached to the side surface of the plate-shaped piece 12a so as to stop the rear half 5b in a horizontal position when switching the lid piece 5 from open to closed. I tried to support it. 17 indicates a non-slip protrusion.

FIG. 5 shows another embodiment, in which the lid piece 3 is integrally molded with the cap body 1, and the connection part with the cap body 1 is the rotating part 9 of the lid piece 5, and its opening/closing operation, etc. Same as the previous example.

Furthermore, FIGS. 6 and 7 show another embodiment, in which the protrusion 11 and its receiving part 12 in the previous example are arranged in reverse, and the protrusion 11 is placed on the cap body 1 side, and the protrusion 11 is placed on the lower surface of the rear half 5b of the lid piece 5. The receiving part 12 is formed in the upper part, and its operation is exactly the same as the previous example.

Furthermore, the protrusion 1 for elastic engagement in each of the above embodiments
The projecting end of No. 1 is formed thin to facilitate fitting into the receiving portion 12.

(Effect of the invention) According to the invention, when opening and closing the drawing hole by the bending action of the lid piece, the bending state of the lid piece when opening is the required linear length with respect to the partition wall surface where the lower end of the front half of the lid piece is fixed. The bent part of the lid piece is placed in a position beyond the dead line, and the lid piece and the cap body are arranged side by side with a gap between the two plate-like pieces. Since it is held by fitting into the plate-shaped protrusion that is press-fitted into the space and engages with friction, the lid piece bent into the open state is reliably held in the bent state, and no accident occurs during the operation of dispensing the contents. This has the effect of accurately preventing the harmful effects caused by the lid piece falling over easily.
