On the outer periphery of the stopper body 14, a tapered surface 14 a that is slanted at the top is provided at the upper end portion, and a latching recess 16 that is recessed except for the rotation-stopping projection 15 is disposed in the middle.

  As shown in FIGS. 1 and 2, the upper lid B is provided with a top wall 20, a side wall 21 that is suspended from the outer edge of the top wall 20, and is connected to the cap body A via a hinge part C on the outer periphery. An opening 22 is bored in the center of the wall 20, and a knob member E for hooking the mortar plug 12 of the cap body A inward when the lid is closed is connected to the inside of the wall 20. And can be opened and closed freely.

  The opening 22 of the top wall 20 is formed according to the shape of the knob member E in plan view, and a slight space is formed between the knob member E and the opening 22 of the knob member E and the top wall 20. The inner side is continuously provided via breakable breakable bridges 23 that are arranged in plural (in this embodiment, four positions at intervals of 90 ° starting from the hinge C side).

  The side peripheral wall 21 is provided with a hinge portion C on one side of the outer periphery, an arc-shaped handle portion 24 is provided on the opposite side of the outer peripheral lower end portion of the hinge portion C, and a cap body at the inner peripheral lower end portion. A base wall engaging portion 25 that is engaged with the upper lid engaging portion 6 of A to maintain the closed state is provided.

  As shown in FIGS. 1 and 2, the knob member E is a plan view from the outer periphery of the engagement cylinder part 30 and the engagement cylinder part 30 at the center for engaging the mortar plug 12 of the cap body A inward when the lid is closed.

An anti-rotation groove 32 is recessed, and an engagement protrusion 33 that fits into the engagement recess 16 of the mortar plug 12 of the cap body A is provided at the lower end of the inner periphery, except for the anti-rotation groove 32. .
The latching protrusion 33 is formed of an upper horizontal surface 33a extending inwardly and horizontally, and an inclined surface 33b extending outward from the tip of the horizontal surface 33a and extending to the lower end of the engagement cylinder portion 30.

Next, usage modes and operational effects of the present embodiment will be described with reference to the drawings.
As shown in FIG. 2A, the cap of this embodiment is manufactured by integral molding with the cap main body A via the hinge portion C in a state where the upper lid B is completely opened.

Next, when the upper lid B is closed and the cap is set as shown in FIG. 1 from the opened state, if the handle portion 24 of the upper lid B is held and rotated around the hinge portion C, the knob member E The anti-rotation protrusion 15 of the mortar plug 12 of the cap main body A is inserted into the inward of the anti-rotation groove 32 provided on the inner periphery of the engagement cylinder part 30, and the inner peripheral lower end of the engagement cylinder part 30 The inclined surface 33b of the latching projection 33 provided on the upper surface of the hook 12 comes into contact with the tapered surface 14a at the upper end of the mug plug 12, and the lower part of the engaging cylinder portion 30 is slightly deformed by the inclination of each other.
In this case, the breaking strength of the breaking bridge 23 is set to be greater than the resistance to climb over the engagement cylinder portion 30 so that the knob member E is not separated from the upper lid B.
In addition, the latching projection 33 of the engagement cylinder part 30 is provided with an inclined surface 33b, and a tapered surface 14a is provided at the upper end of the mortar plug 12 so that they can easily get over each other. The overcoming resistance of 30 does not need to be so great.

Further, when the upper lid B is closed, the upper surface of the top wall 20 of the upper lid B and the upper surface of the knob member E (that is, the entire top surface of the upper lid B) are pressed to close the upper lid B so that the breaking bridge 23 does not break. It can also be covered.
In this case, the breaking strength of the breaking bridge 23 can be set to be smaller than the resistance overcoming the engagement tube portion 30.

Finally, as shown in FIGS. 1 and 2B, the tip of the latching projection 33 of the engagement cylinder 30 is fitted into the latching recess 16 of the mortar plug 12 and latched. The upper lid engaging portion 6 engages with the base wall engaging portion 25 of the side peripheral wall 21 of the upper lid B, and is closed as an unopened state.
In the cap with a mortar plug of this embodiment, the mortar plug 12 is protected within the knob member E and the upper cover B by closing the upper lid B after molding. Can be prevented from breaking.

Next, the cap with the upper lid B closed is attached to the mouth 1 of the container D filled with the content liquid.
In the mounting step, the mounting portion 3 of the cap main body A is applied to the mouth portion 1 of the container D, and the cap is rotated so that the male screw portion 2 of the mouth portion 1 and the female screw of the outer cylinder 9 of the mounting portion 3 of the cap main body A. The part 10 is screwed and attached.
In this embodiment, the cap is mounted on the container D by screwing the male threaded portion 2 of the mouth 1 of the container D and the female threaded portion 10 of the outer cylinder 9 of the cap body A, but this is not necessarily the case. However, the present invention is not limited to such means, and a protrusion that engages with each of the mouth portion 1 and the outer cylinder 9 may be provided, and the cap may be attached by other means such as stoppering.

  In the container equipped with the cap with a throat plug of the present embodiment, the throat plug 12 of the cap body A is mounted on the knob member E, and the side surface of the knob member E is located inside the top wall 20 opening 22 of the upper lid B and Since it is protected by the side peripheral wall 21, it is possible to prevent the mortar plug 12 from being bent or broken with respect to the nozzle 5 of the cap main body A due to external force during distribution.

When using the content liquid in the container D, when opening the cap for the first time, lift the finger from the notched recess 9a of the outer cylinder 9 of the cap body A shown in FIG. Then, the engagement between the upper lid engaging portion 6 of the cap body A and the base wall engaging portion 25 of the upper lid B is released, and the upper lid B is rotated around the hinge C.
Then, although the knob member E also tries to be lifted together with the upper lid B, the horizontal surface 33a of the latching projection 33 of the engagement cylinder part 30 of the knob member E is latched by the latching recess 16 of the mug plug 12. Since the breaking strength of the breaking bridge 23 is set to be smaller than the pulling resistance of the engagement cylinder portion 30, the breaking bridge 23 is broken sequentially from the direction opposite to the hinge portion C, and finally the hinge portion The C-side breaking bridge 23 is also broken, and when the knob member E is completely separated from the opening 22 of the upper lid B, the knob member E is in a state where it has shifted to the upper surface of the mortar plug 12 as shown in FIG. The lid is opened.
Of course, the breaking strength of the breaking bridge 23 is set to be smaller than the breaking strength of the thin portion 11 of the mortar plug 12.

  When the cap of the present embodiment is not opened, the engaging cylinder portion 30 of the knob member E of the upper lid B is hooked on the latching recess 16 of the mortar plug 12, so that the top lid is forcibly moved from the unopened state. When B is opened and closed, the breaking bridge 23 connecting the opening 22 of the top wall 20 of the upper lid B and the knob member E is broken, and even if the upper lid B is closed again, the knob member E and the top wall 20 of the upper lid B are closed. Since the breaking bridge 23 with the opening 22 is broken, it can be easily visually confirmed that the opening / closing is illegal.

Next, from the state shown in FIG. 3, the rotation stop groove of the engaging cylinder portion 30 of the knob member E is rotated together with the rotation of the knob member E by hooking and twisting a finger on both or one of the knob portions 31 of the knob member E. 32, the engagement of the cap body A of the cap body A fitted into the rotation stop projection 15 of the throat plug 12 is twisted with respect to the nozzle 5, the thin portion 11 is broken, and the throat plug 12 is removed from the nozzle 5. As shown in FIG. 4, the nozzle hole 13 is opened at the tip 5 a of the nozzle 5 and the nozzle 5 is opened.
By opening the nozzle 5 of the cap body A, as shown in FIG. 5, the content liquid in the container D can be easily poured out from the nozzle 5 simply by tilting the container D.

Since the cap of the present embodiment is basically for a container where the content liquid is used up once, after the content liquid is poured out from the container D, it is discarded as it is.
In addition, after twisting off the mortar plug 12 and opening the nozzle hole 13 of the nozzle 5, it cannot be closed again, and the space of the opening 22 of the top wall 20 of the upper lid B is open. The lid can be confirmed by visual recognition, and the usage status of the container can be surely known.
The container D is not limited to the one that tilts and discharges the content liquid from the nozzle 5, but may be one that squeezes the container D and discharges the content liquid from the nozzle 5.

In this embodiment, rotation stopper protrusions 15 are provided on the plug 12 at 90 ° and 270 ° positions with the opposite side of the hinge C as 0 ° in a plan view of the outer periphery of the plug body 14, and accordingly. The knob member E is provided with the knob portion 31 and the rotation stop groove 32 at the positions of 90 ° and 270 °, but when the lid is closed, the rotation stop protrusion 15 is inserted into the rotation stop groove 32 and engaged. After opening the lid, it is only necessary to twist the knob member E by placing the finger on the knob 31 and twisting the knob member E. The rotation stop groove 32 may be provided in accordance with the location and number of the rotation stop projections 15, and the location and number of the knobs 31 are also hooked with fingers. As long as the knob member E can be twisted off, what is the location and number? Something like that.
The location and number of the rotation stop protrusions of the mortar plugs, the knob portions of the knob members, and the rotation stop grooves are not limited to the above-described embodiment.

Next, a second embodiment in which the shapes of the upper lid B and the knob member E of the first embodiment are changed will be described with reference to the drawings.
In the following, the same components as those in the first embodiment are denoted by the same reference numerals, and the changed portions of the plug body are denoted by new symbols, and the differences will be mainly described.

  In FIG. 6, A is a cap body mounted on the container D, and Ba is an upper lid attached to the cap body A via a hinge portion C so as to be opened and closed.

  As shown in FIGS. 6 and 7, the upper lid Ba has a side peripheral wall 35 connected to the cap body A via a hinge portion C on the outer periphery, and an inner peripheral upper end of the side peripheral wall 35 as an opening 36. And a knob member F provided continuously through breakable break bridges 37 arranged in a plurality (in this embodiment, four locations at intervals of 90 ° starting from the hinge portion C side). Yes.

  The side peripheral wall 35 has a hinge portion C continuously provided on one side of the outer periphery, a handle portion 24 is provided on the opposite side of the outer peripheral lower end portion from the hinge portion C, and a base wall engaging portion 25 is provided on the inner peripheral lower end portion. It has been.

  The knob member F has a ring shape in which an outer edge forms a slight space between the opening 36 and an engagement hole 40 is formed in the center in the shape of the slot 12 of the cap body A in the plan view. The upper plate 41 includes an engagement cylinder portion 42 that is suspended from the edge of the engagement hole 40 of the upper plate 41.

  The engagement hole 40 has a central portion 40a formed in the outer peripheral shape of the plug body 14 of the mortar plug 12, and a rotation stop portion 40b formed in the shape of the rotation stop protrusions 15 of both the mortar plug 12 from the central portion 40a. It is made up of.

  On the lower surface of the upper plate 41, a bent groove 43 that is positioned on both sides of the hinge portion C side and the opposite side in the vicinity of the outer edge of the engagement cylinder portion 42 and extends in parallel with the rotation stopper portion 40 b is recessed. The bent groove 43 is divided into a central substrate portion 44 and a grip plate portion 45 formed in a D shape on both sides thereof.

The engagement cylinder portion 42 has an inner periphery formed with a rotation stop groove 46 extending from the inner periphery to the lower end of the rotation stop portion 40b. A latching protrusion 47 that projects into the latching recess 16 of the stopper 12 is provided.
The latching protrusion 47 is formed of a horizontal plane 47a that extends inwardly in the upper part of the upper part and an inclined surface 47b that extends outward from the tip of the horizontal plane 47a and extends to the lower end of the engagement cylinder part 42.

Next, usage modes and operational effects of the present embodiment will be described with reference to the drawings.
When closing the top cover Ba and setting the cap, if the handle part 24 of the top cover Ba is held and the hinge part C is rotated around the hinge part C, the rotation stop groove 46 provided in the engagement cylinder part 42 of the knob member F will be described. The rotation stop projection 15 of the throat plug 12 of the cap body A is inserted into the inner side of the cap body A, and the inclined surface 47b of the latch projection 47 provided at the lower end on the inner periphery of the engagement cylinder portion 42 is a throat plug. 12 abuts against the tapered surface 14a at the upper end of the twelve, and gets over while slightly deforming the lower portion of the engagement cylinder portion 42 due to the inclination of each other.
In this case, the breaking strength of the breaking bridge 37 is set to be larger than the resistance overcoming the engaging cylinder portion 42 so that the knob member F is not separated from the upper lid Ba.
In addition, the latching projection 47 of the engagement tube portion 42 is provided with an inclined surface 47b, and a tapered surface 14a is provided at the upper end of the throat plug 12 so that they can easily get over each other. The resistance to overcoming 42 does not need to be so great.
Naturally, when closing the upper lid Ba, the upper lid Ba is pressed against the upper end surface of the side peripheral wall 35 of the upper lid Ba and the top surface of the knob member F (that is, the entire top surface of the upper lid Ba) so that the fracture bridge 37 does not break. The lid may be closed.

Finally, as shown in FIG. 6, the tip of the latching projection 47 of the engagement tube portion 42 is fitted into the latching recess 16 of the mug plug 12 and is latched. 6 engages with the base wall engaging portion 25 of the side peripheral wall 35 of the upper lid Ba and is closed as an unopened state.
In the cap with a mortar plug of the present embodiment, the mortar plug 12 is protected in the knob member F and the upper lid Ba by closing the upper lid Ba after molding. Can be prevented from breaking.
Further, even in a container equipped with a cap with a mortar plug, since the mortar plug 12 is protected in the knob member F and the upper lid Ba, the mortar plug 12 receives an external force during distribution to the nozzle 5 of the cap body A. On the other hand, it can be prevented from being bent or broken.

In using the content liquid in the container D, when opening the cap for the first time, the upper lid Ba is rotated with respect to the cap body A around the hinge portion C.
Then, the knob member F tries to be lifted together with the upper lid Ba, but the horizontal surface 47a of the latching protrusion 47 of the engagement cylinder portion 42 of the knob member F is latched by the latching recess 16 of the mug plug 12. The breakage bridge 37 is broken in order from the direction opposite to the hinge portion C, and when the knob member F is completely separated from the opening 36 of the upper lid Ba, as shown in FIG. 12 is moved to the upper surface and opened.
Of course, the breaking strength of the breaking bridge 37 is set to be smaller than the breaking strength of the thin portion 11 of the mortar plug 12.

  When the cap of the present embodiment is not opened, the engaging cylinder portion 42 of the knob member F of the upper lid Ba is latched by the latching recess 16 of the mortar plug 12, so that the top lid is forcibly moved from the unopened state. When Ba is opened and closed, the breaking bridge 37 connecting the opening 36 of the side peripheral wall 35 of the upper lid Ba and the knob member F is broken, and even if the upper lid Ba is closed again, the knob member F and the opening 36 of the upper lid Ba Since the ruptured bridge 37 is broken, it can be easily seen that it has been illegally opened and closed.

Next, as shown in FIG. 9, both the knob plate portions 45 of the upper plate 41 of the knob member F are bent upward with respect to the substrate portion 44 by the bent grooves 43.
Then, the cap main body A fitted into the rotation stop groove 46 of the engaging cylinder portion 42 of the knob member F as well as the rotation of the knob member F by hooking and twisting the fingers so as to pinch the outer surfaces of both the knob plates 45. Due to the engagement of the non-rotating plug 12 with the rotation stop projection 15, the non-rotating plug 12 is also twisted with respect to the nozzle 5, the thin portion 11 is broken, and the non-moving plug 12 is removed from the nozzle 5 together with the knob F. The nozzle hole 13 is opened at the front end portion 5a, the nozzle 5 is opened, and the content liquid in the container D is used.
In the present embodiment, both of the tab plate portions 45 of the tab member F are bent upward with respect to the substrate portion 44 by the bent grooves 43. However, the tab plate portion 45 is separately bent downward and both the tab plate portions 45 are bent. You may make it twist with a finger so that the outer side surface may be picked.

After the nozzle hole 13 of the nozzle 5 is opened, it cannot be closed again, and further, since the space of the opening 36 of the upper lid Ba is open, the lid can be visually confirmed and the container is used. Can be surely known.
About the effect of other composition, it is the same as that of the 1st example.

Next, a third embodiment in which the shape of the knob member F of the second embodiment is changed will be described with reference to the drawings.
