Description

[Detailed explanation of the idea] [Industrial application field] This invention relates to lids for bottles or cans.

[Prior art and its drawbacks] Various bottles or cans (hereinafter referred to as
It is typically called a bottle. ) can be closed by simply screwing a cap-shaped cap with a female thread on the inner wall onto the male thread formed on the outer periphery of the bottle mouth, or by pushing a plug-shaped cap such as a cork into the cap. Only.

Therefore, the cap-shaped lid can be simply turned in the opposite direction, and the plug-shaped lid can be simply pulled out to open the bottle and consume its contents.

Therefore, the lid itself cannot prevent the contents from being consumed by others without permission or from being misused, which can lead to irreversible accidents caused by ignorant children and others ingesting poisonous substances or powerful drugs. Unforeseen disasters continue to occur.

[Technical problem to be solved] In view of the above points, this invention adds a locking mechanism to the lid so that only a person who has set an unlock number etc. to the locking mechanism can unlock and open the lid. The aim is to provide a bottle that can prevent unauthorized consumption and unforeseen accidents.

[Means for solving the problem] In order to solve the above problems, the bottle lid according to this invention has an outer lid that can be manually applied with rotational force, and a female thread that is screwed into the male thread of the bottle mouth. and a locking mechanism is provided between the inner cover which is rotatably and freely raised and lowered within the outer cover, and the locking mechanism is provided with: a protrusion that transmits the rotational force of the outer cover to the inner cover when pulled up and connected to the inner cover; b. a protrusion that is rotatable from the outside of the outer cover between the bottom of the outer cover and the bottom of the inner cover; at least one locking ring having a hole that is fitted into the locking ring and passes through the projection; It is characterized by being composed of many numbers or symbols used for locking and unlocking, each corresponding in position.

[Operation] With the protrusion on the bottom of the outer lid aligned with the hole in the locking ring, rotate the locking ring relative to the outer lid.
One number or symbol on the outer lid corresponds to one number or symbol on the lock ring. This sets the unlock number.

The outer cover is pushed down against the inner cover, and the locking ring is rotated relative to the protrusion of the outer cover to shift the position of the protrusion and the hole. This completes the locking operation.

If you do not know the unlock number, even if you try to remove the outer cover by turning it, the protrusion on the outer cover will not line up with the hole in the locking ring, and will pass through the hole and connect to the bottom of the inner cover. Since the rotational force of the outer lid is not transmitted to the inner lid, the inner lid cannot be uncoupled from the male screw of the bottle mouth, and the lid cannot be removed.

When you turn the locking ring and match the specific number or symbol written on it with the specific number or symbol on the outer cover (both are the unlocking numbers set earlier), the protrusion on the outer cover will lock. It matches the hole in the lock ring, so when you pull up the outer cover, the protrusion passes through the hole,
Its end connects with the bottom of the inner lid. Therefore, when the outer lid is rotated, the rotational force is transmitted to the inner lid, so that the inner lid is rotated as the outer lid rotates, and is detached from the male thread of the bottle hole to open the bottle mouth. can.

[Example of this idea] Next, an explanation will be given based on this idea.

The bottle lid A according to this invention generally includes an outer lid 1 which is always rotatable with respect to the bottle mouth, and is housed within the outer lid so as to be movable in the axial direction, and the bottle mouth is attached to the inner wall surface. an inner cover 2 having a female thread 22 that is screwed into a male thread on the outer periphery; and an inner cover 2 provided between the outer cover 1 and the inner cover 2;
A locking operation in which the outer cover is rotated while the outer cover 1 is pushed down relative to the inner cover prevents the outer cover from being pulled up, prevents the rotational force of the outer cover from being transmitted to the inner cover, and also keeps the outer cover in a predetermined position. It has a locking mechanism that allows the outer cover to be pulled up by an unlocking operation of rotating it to a position and pulling it up, and transmits the rotational force of the outer cover to the inner cover in the pulled up state.

The first embodiment shown in FIGS. 1 to 6 comprises an outer cover 1, an inner cover 2, a gasket 3, a locking ring 4, and a transmission ring 5.

The outer lid 1 has one or more small protrusions 11 at the middle part in the height direction of the inner wall, has a flange 13 projecting horizontally inward at the bottom, and has irregularities in the circumferential direction on the upper surface of the flange 13. A continuous tooth surface is formed.
Further, on the lower part of the outer wall of the outer cover, there are written a number of numbers or symbols used for locking or unlocking as necessary.

The inner cover 2 is formed into a bottomed cylindrical shape having an outer surface height shorter than the inner surface height of the outer cover 1, and is housed inside the outer cover 1 so as to be able to rise and fall freely, and a gasket 3 is fixed to the top and bottom surface of the inner wall. has been done. Two annular grooves 21 and 21' having a depth corresponding to the small projections 11 on the inner wall of the outer cover 1 are formed in the upper part of the outer wall surface of the inner cover 2. When the outer cover 1 is pushed down until it stops against the inner cover 2, the small protrusion 11 fits elastically into the groove 21 on the inner cover 2, and the outer cover 1 is pushed down against the inner cover 2. When the small protrusion 11 is pulled up until it is stopped, the small protrusion 11 is elastically fitted into the groove 21' on the lower side of the inner cover 2.
The distance between the grooves 21 and 21' is set.

Further, a female thread 22 having a required thickness is formed on the upper part of the inner wall to be screwed into a male thread provided on the outer periphery of the bottle mouth, and a ring-shaped thread 22 is formed with a required thickness and extends horizontally from the inner periphery of the lower end of the female thread to the vicinity of the outer wall of the inner lid. Teeth 23 are formed.

An inward protrusion 24 is formed by hanging the outer wall of the inner lid in an annular manner to a point slightly below the tooth surface, and an annular shape corresponding to the thickness of the locking ring 4 is formed between the protrusion 24, the outer wall, and the teeth 23. A fitting space 25 is formed.

The locking ring 4 is fitted into the fitting space 25 so as to be rotatable about the vertical axis but cannot be removed.

The locking ring 4 is formed into an annular shape, has a smooth upper surface, and has similar annular teeth 41 formed on the bottom surface. A plurality of elongated indicator pieces 42 are provided. Different numbers or symbols used for locking and unlocking are written on the outer surface of each indicator piece. The indicator piece 42 protrudes downward from the bottom of the outer lid 1, so rotate it with your fingertips and
Mark the numbers or symbols on any specific indicator piece on the outer cover 1.
It can be positioned to match either the numbers or symbols written on the outer wall surface of.

The locking ring 4 also has a plurality of through holes 43.
are provided at asymmetric positions, preferably at different distances from the center.

The transmission ring 5 is formed into an annular shape substantially similar to the locking ring 4, has similar annular teeth 51 on the bottom surface, has a smooth top surface, and has each of the locking rings on the smooth surface. Projections 52 corresponding in number and position to the through holes are protruded upward and have the same length. A tooth 521 is also provided at the top of this protrusion 52.
is formed.

Therefore, when approaching the locking ring 4 from below and overlapping the transmission ring 5 with the indicator piece 42 passing through the center portion of the transmission ring, if the protrusion 52 does not match the through hole 43, , protrusion 5
21 engages with teeth 41 on the lower surface of the locking ring. On the other hand, when the two rings 4 and 5 are rotated relative to each other and all the through holes 43 and the protrusions 52 are aligned, the protrusions 52 pass through the through holes 43 and the tops of the protrusions Teeth 521 can protrude from the top surface of the locking ring.

The transmission ring 5 is fitted between the bottom surface of the inner cover 2 and the flange 13 of the outer cover 1 so as to be freely movable and rotatable.

With the above configuration, the lid is in the state shown in FIG. 4A when shipped from the factory. That is,
The small protrusion 11 of the outer cover 1 is fitted into the groove 21 on the inner cover 2, and the protrusion 52 of the transmission ring 5 is inserted into the hole 43 of the lock ring 4. Therefore, the lid can be fitted over the bottle mouth and used like a conventional cap-shaped lid.

Next, if you want to lock the lid using the locking mechanism of this lid, remove the lid from the bottle, push down the outer lid 1, and flick the transmission ring 5 with your fingertips as shown in Figure 4B. As shown in the figure, attach the transmission ring 5 to the outer cover 1.
spaced from the flange 13 of. Then, the locking ring 4 and the transmission ring 5 are rotated together via the indicator piece 42, and stopped when any one number or symbol on the outer periphery of the outer cover matches one indicator piece 42a. This means that the unlock number has been set. With the outer cover 1 in Fig. 4B pressed down,
When the outer cover is turned by an arbitrary amount to shift the positional relationship between the hole 43 and the protrusion 52 as shown in FIG. 5A, the lock is locked.

That is, there is no correspondence between each protrusion 52 of the transmission ring 5 and the through hole 43 of the locking ring 4.
Therefore, no matter how much the outer cover 1 is rotated in an attempt to open the cover in this state, the rotational force of the outer cover is only transmitted to the transmission ring and not to the teeth 23 of the inner cover 2. As shown in FIG. 6, the male thread 101 of the bottle 100 is screwed into the female thread of the inner lid 2, and the inner lid 2 is firmly fixed to the bottle.
The inner lid cannot be opened. Thus, the purpose of the lock is achieved.

In order to consume the contents of the bottle 100, it is necessary to unlock the lid A and remove the lid from the bottle mouth. To unlock, hold the lock ring 4 with your fingertips, turn the outer cover 1, and press a specific number (unlock number) on the specific indicator piece 42.
Match a. Figure 5B shows the condition of the box.

This allows the lock to be unlocked. That is, the protrusion 5
2 and the hole 43, so when the outer cover 1 is pulled up, the protrusion 52 passes through the hole 43 and the teeth 521 engage with the teeth 23 of the inner cover, as shown in FIG. 4A.
Therefore, since the rotational force of the outer cover is transmitted to the inner cover,
By rotating the outer lid, the inner lid is rotated together, allowing the lid to be removed from the bottle opening.

One of the many numbers or symbols on the outer periphery of the outer lid 1 is selected as an unlocking number, and when it matches one specific indicator piece, the lock becomes unlockable. Therefore, the more numbers or symbols there are on the outer lid, the more likely it is that someone who does not know the unlocking number will succeed in unlocking the lid of the bottle. Furthermore, if each indicator piece is also provided with numbers or symbols, the effect of preventing unauthorized unlocking will be even greater.

Next, a second embodiment shown in the drawings from FIG. 7 onwards will be described.

This embodiment includes an outer cover 20, an inner cover 30, two indicator rings 40, 60, and two locking rings 50, 7.
Consists of 0.

The outer lid 20 is divided into an upper half 201 formed in a dish shape with a bottom on the upper surface and a lower half 202 having an inward annular flange on the bottom, and the inner diameter of the former is larger than the outer diameter of the latter. The lower half is housed in the upper half so that it can be moved up and down, making it expandable and retractable.
A small protrusion 211 is formed on the upper part of the inner wall of the upper half 201, and a protrusion 221 is provided at an asymmetrical position on the flange surface of the lower half, and has teeth at its end. Further, the lower half portion 202 is provided with a window 222 passing through the inside and outside.

The outer shape of the inner cover 30 is smaller at the upper part than the inner diameter of the upper half of the outer cover, and smaller than the inner diameter of the lower half 202 of the outer cover at the lower part. In this way, the inner lid 30 is housed in the outer lid 20 such that it can be raised and lowered and rotated freely. Further, a female thread 301 is formed on the inner wall of the inner lid 30, and is screwed into a male thread formed on the outer periphery of the bottle mouth.

Further, a single annular groove 302 is formed on the outer wall of the inner lid 30 for fitting and positioning with the small protrusion 211 on the upper half of the outer lid. Furthermore, the inner lid 30 has teeth 303 on the bottom surface, and the protrusion 221 of the lower half 202
When the ends of the outer cover 20 and the inner cover 30 are engaged,
can be rotated in conjunction with each other.

Four fixed legs 30 extend downward from the inner edge of the lower end of the female thread 303 of the inner cover 30 and bend outward at right angles.
4 is provided.

The index rings 40 and 60 have numbers or symbols used for locking and unlocking written on their outer surfaces at equal intervals in the circumferential direction, and locking rings 50 and 70 are provided inside the corner index rings. The index ring can be rotated by applying a certain degree of strong rotational force to the index ring while the locking ring is fixed and is fitted rather tightly.

The locking rings 50 and 70 are similarly formed with continuous annular teeth 502 and 702 on their lower surfaces, and are also provided with corresponding positions on the lower half 2 of the outer lid.
Holes 501 and 701 corresponding to the protrusions 221 of 02 are provided. Therefore, when the two locking rings are rotated relative to each other, their holes 501,
701 are vertically aligned and penetrate. And these two sets of index rings and locking rings 40, 50, 60,
70 are held in a vertically stacked state on the outside of the fully fixed feet 304 of the inner lid 30 so as to be rotatable but not detachable.

A window 222 provided in the lower half 202 of the outer lid 20
A triangular index 223 corresponding to the index rings 40 and 60, respectively, is written on the lower side.

The lid according to this embodiment also has a 9th position when shipped from the factory.
As shown in Figure B, the holes 50 in the two locking rings
1,701 are matched, and the protrusions 221 are inserted into these holes.
is inserted, and the outer lid 20 is in a shortened state. Therefore, it is possible to apply rotational force to the outer cover 20 and transmit it to the inner cover 30.

To lock the lid, push down the lower half of the outer lid as shown in Figure 9A, and then lock the locking rings 50, 70.
With the index ring 40 fixed with the protrusion 221, rotate the upper index ring 40 in the circumferential direction with your fingertips at the window of the outer lid, and mark one of the numbers or symbols on the window 222.
Then, with the lower half 202 of the outer lid further pushed down and the lower locking ring 70 fixed by the protrusion 221, the lower index ring 60 is rotated in the same manner. Then mark any one number or symbol on the outer circumferential surface of the window as a triangular indicator 203.
match. This sets the unlock number.

After setting the unlock number, the lower half 202 of the outer cover is pushed down as shown in FIG. As a result, each set of index ring and locking ring 40,
50, 60, and 70 can be rotated together, so each index ring 40,
60 each by an arbitrary amount. This means that it is locked.

That is, as shown in FIG. 9B, the protrusion 221 of the outer lid is rotated by the rotation of the index ring and the locking ring.
Since the holes 501, 701 of the respective locking rings 50, 70 do not match, even if an attempt is made to pull up the lower half 202 of the outer lid, the protrusion 221 cannot be inserted into the holes 501, 701. When the outer cover 20 is rotated in this state, the upper end of the protrusion 221 is engaged with the lower surface of the lower locking ring 70, so that the outer cover and the locking ring 70 absorb the rotational force of the outer cover. It is not transmitted to the inner lid. Therefore, since the inner lid cannot be loosened from the male screw on the bottle mouth, the lid cannot be removed. Lock ring 50.7
By using two of 0, in case the protrusion 22
1 is aligned with the hole 701 of the lower locking ring, the protrusion is aligned with the hole 50 of the upper locking ring 50.
1 does not match, so the probability that someone who does not know the unlock number will succeed in illegally unlocking the lock by guessing is extremely low.

Now, if the person who locked the bottle wants to unlock it in order to consume the contents inside the bottle, after sufficiently pushing down the outer lid lower half 202 of the lid in the locked state of No. 9B, press the two index rings 40, 60 in the window 222 with a fingertip to match a specific number, symbol, etc. on each index ring with the index 203 on the window. As a result, the holes 501 and 701 of the locking rings 50 and 70 are connected to the protrusion 22 of the outer lid as shown in FIG. 9B (b).
Positionally matches 1.

In this state, when the lower half 202 of the outer cover is pulled up, the protrusions 221 pass through the holes of each locking ring,
The teeth at the upper end of each protrusion are the teeth 303 at the bottom of the inner lid 20.
mesh with each other. Therefore, when the outer lid is turned, the rotational force is transmitted to the inner lid via the protrusion 221, so that the inner lid is loosened from the external thread of the bottle opening, and the lid can be removed from the bottle.

[Effects of this invention] According to this invention, as described above, a locking mechanism equipped with an index means that allows setting of an unlocking number from the outside is incorporated between the outer lid and the inner lid, and the unlocking number is set. After setting, it is locked by turning the locking ring a desired amount.
The outer cover and inner cover can be connected by turning the lock ring until the set unlock number matches the index, so someone who does not know the unlock number can do so without permission. Since the contents cannot be consumed by opening the lid, unauthorized consumption and unexpected accidents can be prevented.
