Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a dispensing cap that is assembled to a container containing granular or powdery contents, and the opening and closing posture of the lid plate body that opens and closes the dispensing opening. The purpose is to stably hold the

[Conventional technology]

There are various structures for dispensing caps that are attached to containers containing granular or powdered contents, but in some cases the dispensing opening formed in the cap body is rotatably assembled to the cap body. A structure that opens and closes with a cover plate is convenient for use.

However, in a shaker cap with this type of structure, when the container is shaken to shake out the contents, the lid plate in the open position shakes violently due to the above-mentioned shaking operation, and the contents are easily shaken out. There is an inconvenience in that it is not possible to smoothly dispense the contents, and in use, it is necessary to shake out the contents while pressing the lid plate in the open position with the fingertips.

As a solution to this inconvenience,
The structure of the drawing cap has been proposed in Publication No. 2780 and Publication No. 56-34614 of Utility Model Publication.
The structure of the swing-out cap shown in Publication No. 32-2780 is such that a cover plate is rotatably attached to the cap body, and a spring is stretched between the cap body and the rear end of the cover plate. The elasticity of this spring maintains the open/closed position of the lid plate relative to the cap body. Also, Jikko 56-
The structure of the dispensing cap shown in Publication No. 34614 is such that the lid plate is rotatably assembled to the cap body, and a desired frictional resistance is created between the rotating shaft portion of the lid plate and the cap body. This frictional resistance force is used to maintain the open/closed position of the lid plate relative to the cap body.

[Problem that the invention attempts to solve]

The above-mentioned conventional technology can certainly achieve the effect of holding the lid plate body in a fixed opening/closing position with respect to the cap body, but
In the case of the device shown in Publication No. 2780, a special spring must be used, which increases the number of components and makes the assembly work troublesome. Since the space required increases, the overall size becomes unnecessarily large, which is an inconvenience.In addition, in the case of the one shown in Japanese Utility Model Publication No. 56-34614, the cover plate body is not fixed to the cap body. Since holding in position is attempted to be achieved solely by rotational frictional force between the cap body and the cover plate, the holding force against the cover plate is not sufficient, and as the number of times of use increases, the cover plate The holding force against the body is reduced, and this frictional resistance force against the lid plate acts on the rotational movement of the lid plate, so the opening and closing rotation of the lid plate inevitably becomes awkward. It was not possible to smoothly open and close the lid plate.

Furthermore, as typified by the above-mentioned two prior art techniques, this type of conventional shakeout cap is constructed so that the rear end of the lid plate body is rotatably attached to the cap body. When opening the plate, you will have to hook your fingertips on the tip of the cover plate, and as a result, dirt or moisture from your fingertips will adhere to the cover plate, or conversely, the contents that may have adhered to the cover plate. There was a problem with the discomfort caused by objects sticking to the fingertips.

The problem with this conventional example is that although it is appropriate to use elasticity as a means to maintain the rotational position of the lid plate relative to the cap body, it is necessary to use a dedicated member as the source of elasticity, or to maintain the position of the lid plate relative to the cap body. This is due to the fact that the mode of action of the elasticity is simple friction, and also because the pivot axis of the cover plate relative to the cap body is uniformly set at the rear end of the cover plate.

The present invention was devised in order to solve the problems in the conventional example described above, and when achieving the rotational position holding force of the lid plate body with respect to the cap body by using the elasticity of the constituent members, the present invention A locking means that utilizes elasticity is provided in the rotary assembly portion of the lid plate body, and a portion that facilitates opening and closing operations on the cap body is integrally formed in the lid plate body, in addition to the portion that opens and closes the dispensing opening of the cap body. This is the technical issue.

[Means for solving problems]

Hereinafter, the present invention will be explained with reference to the drawings showing one embodiment of the present invention.

The means of the present invention includes a cap body 1 that is attached to the opening 20 of the container 19, and a lid plate 11 that opens and closes the dispensing opening 4 of the cap body 1. The cap body 1 has a top plate of a crested cylinder. 3, a recessed notch 5 provided in the rear half of the top plate 3, and a bearing recess 6 formed at both ends of the recessed notch 5.
A first locking recess 7 for holding the cover plate 11 in the closed position and a second locking recess 8 for holding the cover plate 11 in the open position on the circumferential surface of the bearing recess 6; The lid plate body 11 has a large number of plug pieces 12 protruding from the first half of the lower surface of the plate body large enough to cover the top surface of the cap body 1 to fit into the dispenser opening 4, and a plate serving as a base material. A mounting piece 13 is provided on the lower surface of the body, leaving an extension piece 16 at the rear end of the rear half facing the concave notch 5 of the body; A shaft cylinder piece 14 having a shape obtained by cutting out a part of the cylinder wall of a short cylindrical piece to be fitted into the shaft cylinder piece 14;
and a locking enlarged portion 15 that locks in the locking recesses 7 and 8 of.

[Function] The bearing recess 6 is opened upward with a width such that the shaft cylinder piece 14 fitted and assembled into the bearing recess 6 does not easily come off. Assembling of the lid plate body 11 to the cap body 1 is achieved by forcibly fitting the caps 14 from above.

The first and second locking recesses 7 and 8 are located apart at a predetermined center angle with respect to the imaginary center of the bearing recess 6, and the first and second locking recesses 7 and
The lid plate body 11 is opened to the cap body 1 by the central angle with the locking recess 8.

The shaft cylinder piece 14 is made elastically deformable by cutting off a part of the cylinder wall of the short cylindrical body and making the cross-sectional shape almost C-shaped.
In addition, the locking bulge 15 can be smoothly removed from the locking bulge 15 from the locking bulge 8 , and the locking force of the locking bulge 15 to both the locking recesses 7 and 8 can be appropriately set.

In the closed position of the cover plate body 11 in which the plug piece 12 of the cover plate body 11 is fitted into the dispenser opening 4, the locking enlarged portion 15 locks in the first locking recess 7; The locking force prevents the lid plate body 11 from accidentally rotating relative to the cap body 1 and maintains the closed state, so even if the container 19 falls, the impact caused by the fall of the container 19 will Since the lid plate body 11 is never opened and the container 19 is kept closed, there is no possibility that the contents will be dispensed illegally.

When a push-down operation force is applied to the extending piece 16 of the cover plate body 11 from this closed state, this push-down force acts as a turning force on the cover plate body 11, so that the shaft cylinder piece 14 is elastically deformed. and its locking ampulla 1
5 from the first locking recess 7, and the lid plate body 1 is removed.
1 rotates in the opening direction using the shaft cylinder piece 14 as a rotation axis until the locking bulge 15 locks in the second locking recess 8 . It is stopped and held at the rotational position where it is locked.

This open position of the lid plate body 11 with respect to the cap body 1 is maintained by the locking force of the locking bulge 15 against the second locking recess 8, so that the lid plate body 11 swings freely when the contents are dispensed. There will be no movement and the contents will be dispensed well.

Closing of the lid plate body 11 is achieved simply by applying a downward force to the upper surface portion of the body of the lid plate body 11 provided with the stopper piece 12.

As described above, in the swinging cap of the present invention, the locking enlarged portion 15 is locked in the first and second locking recesses 7 and 8 by the elasticity of the shaft cylinder piece 14, which is formed into a structure that is easily deformed. To achieve separation,
Smooth rotation of the lid plate 11 can be obtained, and the lid plate 11 can be stably maintained in the closed and open positions with respect to the cap body 1, and furthermore, the opening/closing operation of the lid plate 11 can be easily achieved. is the cover plate body 11
This is achieved by operating the fingertips on the extension piece 16 or the upper surface of the cover plate body 11, which is the rear end portion.
There is no fear that dirt from the fingertips will adhere to the tip of the lid plate body 11, or conversely, the contents will adhere to the fingertips.

In the case of the illustrated embodiment, a thread 9 is carved on the inner peripheral surface of the assembly tube 2 of the cap body 1, and the cap body 1 has a structure in which it is screwed and assembled into a mouth pipe 20 having a thread provided on the outer peripheral surface. It's summery.

Further, a circumferential step portion 10 is formed at the peripheral edge portion of the first half of the top plate 3, and this circumferential step portion 10 is
When the cap body 1 is in the closed state, the lid plate body 11
Peripheral protrusion 18 provided on the peripheral edge of the first half of the lower surface of
This is to improve the sealing effect of the dispenser opening 4 as much as possible by bringing them into close pressure contact, and to prevent the vicinity of the dispenser opening 4 from becoming damp.

The cutout portion formed in the shaft cylinder piece 14 needs to be formed in a position that does not interfere with the function of the shaft cylinder piece 14 as a rotation shaft, but the function of the rotation shaft alone is considered. In this case, it is advantageous to provide the bearing recess 6 at a position that does not face the circumferential surface, but the locking bulge 15 must be provided, and the first and second locking recesses of the locking bulge 15 are It is necessary to ensure that the locking switching operation to 7 and 8 is performed smoothly, and that the mounting piece 13
Considering the strength of the connection with the connector, it is best to install it approximately at the position shown in the figure.

In the case of the illustrated embodiment, the planar shape of the cover plate body 11 is a simple flat disk shape, so it is difficult to judge the front and back relationship from the appearance. It is preferable to provide a finger hook protrusion 17 on. As described above, by providing the finger hook protrusion 17, it is possible to judge the front and back of the dispenser container at a glance, and by hooking the tip of a finger on the finger hook protrusion 17, the opening operation of the lid plate body 11 is facilitated. becomes.

[Effect of idea]

As is clear from the above description, the dispenser cap according to the present invention is composed of only two parts, the cap body and the lid plate, and both parts can be assembled by simply fitting them together. It is easy to assemble, and the closed and open positions of the lid plate relative to the cap body can be controlled by utilizing the elastic deformation of the sufficiently large shaft cylinder piece and the locking action between the cap body and the lid plate body. Since the lid plate is held in place, the posture of the lid plate body is stable and reliable, and the lid plate body can be opened and closed smoothly. Since there is no soiling or soiling of the fingertips with the contents, the shaker container can be used comfortably and has many excellent effects.
