Description

The present invention relates to a cap structure with a so-called child resistance function, and more specifically to a combination of a safety cap and a container that can be opened and closed efficiently with a small number of parts.

BACKGROUND ART Container units equipped with caps that can contain and seal liquid have been widely used. Examples of liquids that can be stored in such containers include water, tea, and chemicals. The chemicals contained in containers require careful handling, so it is necessary to devise measures to prevent users with immature judgment, such as young children, from accidentally opening the container (so-called child resistance function).

Safety caps such as those shown in Patent Documents 1 to 3, for example, are known as cap structures with such a design.
For example, Patent Document 1 discloses a push-and-turn child cash register stand closing device that includes an inner cap member and an outer cap member and rotates the outer cap member while pushing the outer cap member downward when opening the bottle. Furthermore, in Patent Document 2, a locking elastic body having an undercut inside the lower part that locks into an undercut of the bottle jaw when the bottle is closed is connected to the lower part of the cap that is screwed onto the bottle mouth, while when the bottle is opened, A safety cap has been proposed which has a structure in which the queen part of the locking elastic body is pressed inward to rotate about the connecting part as a fulcrum, thereby releasing the undercut lock.

On the other hand, in Patent Document 3, the lid 110 includes a lid 110 with a pair of locking tabs 120, 120', and a container 150 with a pair of stationary locking lugs 164, 164' corresponding to the enlarged portion 164. A lid and container combination is shown in which the locking tabs and stationary locking lugs are disengaged by pressing on the lower portions of a pair of movable panels 116 during removal from the container.

As mentioned above, a safety cap with a child resistance function must not be easily opened by children, etc., and must also have a simpler structure and be manufactured at low cost. However, these characteristics are in a trade-off relationship, and if the opening mechanism becomes complicated, the cost will increase accordingly.

In view of the above background, first of all, in the two-piece safety cap illustrated in Patent Document 1 mentioned above, an increase in cost is unavoidable since the number of parts increases.
On the other hand, the safety caps shown in Patent Documents 2 and 3 can reduce costs in terms of the number of parts, but because they have a relatively simple structure, there is a risk that children may grasp them and unintentionally open the caps. The possibility of this being done cannot be denied.

As described above, in the prior art including the above-mentioned patent documents, no structure has been proposed yet that can overcome the above-mentioned antinomy relationship in a safety cap having a child-resistance function.

Embodiments for suitably implementing the present invention will be described below.
In this embodiment, for convenience of explanation, the X, Y, and Z directions are appropriately set in the explanation using the drawings, but this is for convenience of explanation and does not limit the present invention excessively.
Furthermore, in the following embodiments, an example will be described in which the safety cap 100 is attached to a container 200 that includes at least a mouth portion 200a and a shoulder portion 200b.

However, various structures can be applied to the structure of this container 200 other than those shown in the drawings. For example, in addition to a general container such as a bottle or jar that includes the mouth part 200a of the container as a part, the main body may be a drinking spout that is separately attached. It may also be applied to structures such as. In other words, containers 200 applicable to the present invention include spouts as well as bottles as long as they have a mouth portion 200a and a shoulder portion 200b.

[Safety cap 100]
Hereinafter, as an example, the safety cap 100 attached to the above-mentioned container 200 will be described in detail with reference to FIGS. 1 to 6 as appropriate.
As shown in FIG. 2 and the like, the safety cap 100 according to the present embodiment has a function of screwing into the mouth portion 200a of the container 200, which has an engaging portion 210 on the shoulder portion 200b.

As can be understood from FIGS. 2 to 5, such a safety cap 100 includes a top plate 10, an outer peripheral wall 20 hanging from the top plate 10, and at least two movable panels 30 that are pressed and moved when the cap is opened. It is configured to include an engaged part 40 that is connected to the movable panel 30 and is movable in conjunction with the pressing of the movable panel 30, and an inner circumferential wall 50 that hangs down from the top plate 10 inside the outer circumferential wall 20. has been done.

The material of the safety cap 100 is not particularly limited, but may be made of a known synthetic resin (for example, olefin resin such as polyethylene or polypropylene) that can be manufactured by injection molding, which can be mass-produced.
Furthermore, in this embodiment, a cap with a double wall structure having the inner peripheral wall 50 on the inner peripheral side than the outer peripheral wall 20 is exemplified, but the safety cap 100 does not necessarily have to have a double wall structure. For example, when the inner circumferential wall 50 is omitted and only the outer circumferential wall 20 is provided, a movable panel 30, which will be described later, is added to the outer surface of the outer circumferential wall 20, while a threaded portion 100S, which will be described later, is provided on the inner surface. The Rukoto.

As shown in FIGS. 2 and 3, in this embodiment, an outer peripheral wall 20 as a skirt wall hangs down from the outer peripheral edge of the top plate 10, and a part of this outer peripheral wall 20 is cut out to provide a movable panel 30. has been done. As a more specific arrangement mode, the movable panel 30 in this embodiment may be connected to the outer peripheral wall 20 via a connecting part 31 arranged at the center in the axial direction (Z direction).
As shown in FIG. 2, the outer circumferential wall 20 in this embodiment has a trapezoidal side view in which the diameter decreases from the lower end to the upper end in the axial direction. It may have a cylindrical shape.

Further, as understood from these figures, the inner circumferential wall 50 is formed to hang down on the inner circumferential side of the outer circumferential wall 20 on the back side of the top plate 10.
Furthermore, as is clear from FIG. 2, the axial height of the inner peripheral wall 50 (height in the axial direction from the top plate 10) is set to be smaller than the axial height of the outer peripheral wall 20. This corresponds to the shape of the mouth portion 200a of the container 200, so that the action of the engaged portion 40 and the engaging portion 210, which will be described later, is not inhibited.

As shown in FIGS. 2 and 5, a threaded portion 100S is provided on the inner surface of the inner peripheral wall 50. There are no particular limitations on the specific example of this threaded portion 100S, and various shapes can be applied as long as they can be threaded together with a threaded portion 200S of a container 200, which will be described later. As an example, in this embodiment, a double thread thread is employed as the threaded portion 100S.

<Movable panel 30>
The movable panel 30 in this embodiment will be described in detail below with appropriate reference to FIGS. 2 to 5.
As is clear from these figures, the safety cap 100 of this embodiment includes at least two first movable panels 30A and a second movable panel 30B that are moved by being pressed by the user when the cap is opened. Although two movable panels 30 are illustrated in this embodiment, any number of movable panels 30, greater than or equal to three, may be provided as long as the installation space allows.
Further, the intervals between the movable panels 30 may be set to be equally spaced in the circumferential direction (around the axis). For example, in the present embodiment shown in FIG. 1, two movable panels 30 are arranged at 180° intervals, but in the case of three movable panels 30, they may be arranged at 120° intervals, In the case of four movable panels 30, they may be arranged at 90° intervals.

The first movable panel 30A is configured to have a first thick portion 32 on the upper inner peripheral side in the axial direction (Z direction). In this embodiment, the first movable panel 30A is connected to the outer peripheral wall 20 via a connecting portion 31.
Further, as shown in FIG. 4A, the connecting portion 31 of the first movable panel 30A is provided approximately at the center of the outer peripheral wall 20 in the axial direction (Z direction). Thereby, it is possible to tilt the outer peripheral wall 20 like a seesaw using the connecting portion 31 at the center as a base point.

Furthermore, an anti-slip process 34 may be applied to a portion of the first movable panel 30A lower than the connecting portion 31 in the axial direction. As an example of such anti-slip processing 34, a known processing method such as surface roughening such as knurling or sandblasting may be employed.
As described above, this first movable panel 30A has a pressing portion (an area where the anti-slip processing 34 is applied) downward in the axial direction, so it can also be said to be a downward pressing type movable panel. Note that the anti-slip processing 34 is not essential and may be omitted as appropriate.

As understood from FIG. 3 and the like, in this embodiment, the second movable panel 30B is provided on the outer peripheral wall 20 so as to face the first movable panel 30A across the center (axis) of the top plate 10. There is. Note that the above is an example, and the first movable panel 30A and the second movable panel 30B do not necessarily have to face each other across the axis (the center of the top plate).

As shown in FIG. 5, the second movable panel 30B has a second thick portion 33 on the lower inner peripheral side in the axial direction (Z direction). This second movable panel 30B is also connected to the outer peripheral wall 20 via a connecting portion 31 in the present embodiment, similarly to the first movable panel 30A.
That is, as shown in FIG. 4(b), the connecting portion 31 of the second movable panel 30B is also provided approximately at the center of the outer peripheral wall 20 in the axial direction (Z direction).
As a result, when both the first movable panel 30A and the second movable panel 30B are pressed in parallel, the engaged portion 40 of the first movable panel 30A moves inward, and the second The engaged portions 40 of the movable panel 30B can each move outward.

Here, as shown in FIG. 4, the first movable panel 30A and the second movable panel 30B in this embodiment are each pressed so that they have alternate axial heights when the bottle is opened. More specifically, as shown in FIG. 4, the lower region DA located below the connecting portion 31 of the first movable panel 30A is pressed, and the lower region DA located above the connecting portion 31 of the second movable panel 30B is pressed. The upper area UA will be pressed.
That is, "alternate axial heights" in the present embodiment is defined as positions or areas that are pressed at the time of opening the caps at different heights in the axial direction (Z direction).
Note that as shown in the figure, the first movable panel 30A and the second movable panel 30B are connected through the connecting portion 31 at the center of the outer peripheral wall 20, but the present invention is not limited to this embodiment. For example, the above-described connecting portions 31 may be provided at the upper end of the outer peripheral wall 20 (also referred to as the periphery of the top plate 10), or may be provided at the lower end of the outer peripheral wall 20. In other words, the connecting portion 31 serving as the tilting base point of the movable panel 30 may be located at the center of the outer circumferential wall 20, or the base point may be at the upper end or lower end of the outer circumferential wall 20. However, as will be described later, in this embodiment, the engaged portions 40 shift in the inner and outer circumferential directions following the tilting of the movable panel 30. Therefore, in order to ensure this amount of shift, the connecting portion 31 is connected to the movable panel 30. It is desirable that the outer circumferential wall 20 be located at the axial center of the outer peripheral wall 20 and at the axial center of the outer peripheral wall 20 .

In addition, as shown in FIG. 3, in this embodiment, the first movable panel 30A and the second movable panel 30B each have a portion of the outer circumferential wall 20 flush with the outer circumferential surface of the outer circumferential wall 20. It may be accommodated with a cutout. However, the present embodiment is not limited to this aspect, and for example, the movable panel 30 may protrude outward in the radial direction with respect to the outer peripheral wall 20, or conversely may be recessed inward. .

Further, as shown in FIG. 4(b), the above-described anti-slip processing 34 may be applied above the connecting portion 31 in the second movable panel 30B in the axial direction. Therefore, this second movable panel 30B can also be said to be a top-press type movable panel. Note that similarly to the first movable panel 30A, the anti-slip processing 34 applied to the second movable panel 30B may also be omitted as appropriate.
In addition, the above-described first thick part 32 and second thick part 33 have a rib-like structure intermittently formed in the circumferential direction on the back surface of the movable panel 30 (the side facing the inner circumferential wall 50). Although the example is not limited to this, the shape in which the thick part is continuous in the circumferential direction (in this case, the area of the movable panel where the thick part is formed is thicker in the radial direction than other areas) (in a thick form).

<Engaged portion 40>
Next, the engaged portion 40 in this embodiment will be described in detail with reference to FIGS. 2, 5, and 6 as appropriate. That is, the safety cap 100 of the present embodiment is configured to include an engaged portion 40 that is connected (coupled) with the movable panel 30 described above and is movable in conjunction with pressing the movable panel 30.
More specifically, as shown in FIGS. 5 and 6, the engaged portion 40 in this embodiment includes a flange 41 extending inward from the central region of the movable panel 30, and a flange 41 that hangs down from the flange 41. and an engagement wall 42 facing the movable panel 30.

Furthermore, as understood from FIGS. 5 and 6, the engagement wall 42 of this embodiment has a ratchet shape, and an engagement surface 42p is provided at the tip of the engagement wall 42 in the opening direction OD. There is. Furthermore, in the present embodiment, the engagement wall 42 is placed at the tip end in the closure direction CD of the engagement wall 42 constituting the first movable panel 30A, and the engagement wall 42 is located 210 _inches inside the engagement portion 210 (see FIG. 7). ) may be formed with a first relief taper portion _42t1 for passing through. Similarly, at the tip of the engagement wall 42 constituting the second movable panel 30B in the closure direction CD, there is a second relief for allowing the engagement wall 42 to pass to the outside 210 _out of the engagement portion 210. A tapered portion _42t2 may be formed.

As a result, in this embodiment, when the safety cap 100 is first turned in the opening direction OD, the above-mentioned engagement surface 42p and the engagement portion 210 on the container 200 side are located on the same circumference in the radial direction. Because of this, they engage with each other via this engagement surface 42p, making it impossible to open the cap easily. Note that when the user wants to open the safety cap 100 by turning it, the user presses the movable panel 30 so that one of the engaged parts 40 (engaging wall 42) moves inward of the engaging part 210. At the same time, the other engaged part 40 (engaging wall 42) moves outward from the engaging part 210, and is separated from the same circumference, allowing smoother opening.
On the other hand, when the safety cap 100 is turned in the closure direction CD when closing the container, since the engagement wall 42 of the safety cap 100 is provided with the escape taper portion 42t, the engagement on the container 200 side is prevented. The joint portion 210 does not inhibit the movement of the engagement wall 42, allowing smooth closure operation. Note that the first relief tapered portion 42t ₁ and the second relief taper portion 42t ₂ are not essential, and may be omitted as appropriate as long as the engaged portion 40 can be moved to the intended side of the engagement portion 210.

As shown in FIG. 2, the flange portion 41 extends radially inward from the back side of the movable panel 30, but is not necessarily limited to this, and may extend diagonally in the axial direction. may be formed. Further, the length in the circumferential direction and the thickness in the radial direction of the engagement wall 42 illustrated are merely examples, and may be set as appropriate as long as the engagement wall 42 does not unintentionally bend against the engagement portion 210 of the container 200, which will be described later. can.

[Container 200]
Next, the container 200 of this embodiment will be described with reference to FIGS. 7 to 9.
As shown in these figures, the container 200 is combined with the safety cap 100 described above to constitute the capped container unit of this embodiment. Note that the following description will be made using illustrations in which the portion below the shoulder 2000b of the container 200 is omitted, but as mentioned above, the structure below the shoulder 200b may be of any known shape (such as a bottle, a jar, or a spout). may be adopted.

The container 200 includes at least a cylindrical mouth portion 200a in which a spout 220 from which the contents can be poured out is formed, and a shoulder portion 200b that spreads in a flange shape at the base end of the mouth portion 200a. There is.
A threaded portion 200S that can be screwed into the threaded portion 100S of the safety cap 100 described above is formed on the outer surface of the mouth portion 200a.

As shown in FIG. 7 and the like, an engaging portion 210 corresponding to the engaged portion 40 of the safety cap 100 is provided on the shoulder portion 200b. As is clear from the illustration, the engaging portion 210 stands up from the shoulder portion 200b along the axial direction, and is located at the same position in the radial direction from the axis as the engaged portion 40 and on the same orbit. are doing.

As understood from FIGS. 7 and 9, a predetermined gap is formed between the engaging portion 210 and the mouth portion 200a, through which the engaging wall 42 of the engaged portion 40 can pass. In this embodiment, the area between the engaging portion 210 and the mouth portion 200a is defined as 210 _inches inside the engaging portion 210. Further, the outer region of the engaging portion 210 (that is, the region opposite to the inner 210 _in ) is defined as the outer 210 _out of the engaging portion 210.

Further, as shown in FIG. 9, in this embodiment, the end portion of the engaging portion 210 of the container 200 in the closure direction CD (the first relief tapered portion 42t ₁ and the second relief tapered portion 42t ₂ of the engaged portion 40) It is preferable that a third escape taper part _210t3 is formed on the side that comes into contact when the cap is closed, so that the engaged part 40 can be shifted inward or outward.
As a result, even when the engaged portion 40 of either type of the lower push-type first movable panel 30A or the upper push-type second movable panel 30B comes into contact with the engagement portion 210, for example, the above-mentioned escape taper portion Together, it is possible to move the engagement wall 42 in the intended direction (inward or outward).

<State transition of engaged portion 40 and engaging portion 210>
Next, the state transition between the engaged portion 40 of the safety cap 100 and the engaging portion 210 of the container 200 when the cap is closed will be described with reference to FIG. 10 as well.
When closing the capped container unit CU of this embodiment, the user first attaches the safety cap 100 to the opening 200a of the container 200 and rotates it along the closing direction CD. Although the capping direction CD is shown clockwise in the drawing, the capping direction may also be counterclockwise.

Then, as shown in FIG. 10(α), the threaded portion 100S of the safety cap 100 and the threaded portion 200S of the container 200 are screwed together, and the engaging portion 210 of the container 200 and the cover of the safety cap 100 are screwed together before the closure is completed. The engaging portions 40 face (oppose) each other on the same orbit in the circumferential direction. Although the engaged portion 40 of the safety cap 100 appears to be in contact with the shoulder portion 200b of the container 200 in the illustration, it actually moves slightly above the shoulder portion 200b in the closing direction.

When the safety cap 100 is further turned in the closing direction CD from FIG. 10(α), the state changes to the state shown in FIG. 10(β). That is, as is clear from the figure, the plurality of engaged parts 40 of the safety cap 100 shift inward and outward of the engaging part 210 of the container 200, and following this shift, the movable panels 30 also shift respectively. Shift inward or outward.

More specifically, the engagement wall 42 of the engaged portion 40 connected to the first movable panel 30A moves 210 _inches inward of the engagement portion 210 in the container 200. Following this movement of the engaged portion 40 (engaging wall 42) 210 _inches inward, the first movable panel 30A also moves radially inward.

At this time, a first escape taper portion _42t1 is formed on the distal end side in the closing direction CD of the engagement wall 42 connected to the first movable panel 30A, and a third escape taper portion is formed on the engagement portion 210 of the container 200. _210t3 are formed, so that the above-mentioned shift operation can be executed more smoothly. Note that the first relief tapered portion 42t ₁ and the third relief taper portion 210t ₃ are not necessarily essential, and either one or both may be omitted.
In this embodiment, for example, as shown in FIG. 6, the first relief tapered portion _42t1 is inclined toward the circumferential inner side (center side) with respect to the closure direction CD, and becomes gradually narrower at the tip. On the other hand, the second relief tapered portion _42t2 has a tapered shape that gradually becomes narrower toward the circumferential outside (the opposite side from the center) in the closure direction CD. As a result, when the first relief taper portion 42t ₁ and the second relief taper portion 42t ₂ respectively come into contact with the engaging portion 210 during closure, the first relief taper portion 42t ₁ moves radially inward (towards the center). While shifting, the second relief taper portion _42t2 can be shifted radially outward (to the side opposite to the center).

On the other hand, the engagement wall 42 of the engaged portion 40 connected to the second movable panel 30B moves to the outside 210 _out of the engagement portion 210 in the container 200, as shown in FIG. 10(β). Following this movement of the engaged portion 40 (engaging wall 42) outward 210 _out , the second movable panel 30B also moves toward the outer circumferential side in the radial direction.

At this time, a second escape taper section _42t2 is formed on the distal end side in the closing direction CD of the engagement wall 42 connected to the second movable panel 30B, and a third escape taper section is formed on the engagement section 210 of the container 200. _210t3 are formed, so that the above-mentioned shift operation can be executed more smoothly. Note that the second relief taper portion 42t ₂ and the third relief taper portion 210t ₃ are not necessarily essential, and either one or both may be omitted.

When the safety cap 100 is further turned in the closing direction CD from FIG. 10(β), the state changes to the state shown in FIG. 10(γ). That is, as is clear from the figure, closure is completed when the plurality of engaged parts 40 of the safety cap 100 and the engaging part 210 of the container 200 are located on the same circumference in the radial direction.
The state shown in FIG. 10 (γ) shows the plugged state shown in FIG. For example, even if a portion of the first movable panel 30A above the connecting portion 31 is pressed in this state, the first thick portion 32 interferes with the inner circumferential wall 50, making the pressing impossible. Therefore, the engaged part 40 (engaging wall 42) connected to the first movable panel 30A cannot be disengaged from the same orbit as the engaging part 210 of the container 200, and the closed state is maintained.

Similarly, even if the second movable panel 30B is pressed below the connecting portion 31, the second thick portion 33 interferes with the engaging portion 210 of the container 200, making it impossible to press the second movable panel 30B. Therefore, the engaged part 40 (engaging wall 42) connected to the second movable panel 30B cannot be disengaged from the same orbit as the engaging part 210 of the container 200, and the closed state is maintained. .
In this way, when closing the cap, the engaged portion 40 of the safety cap 100 and the engaging portion 210 of the container 200 are located on the same circumference in the radial direction, so that even if the safety cap 100 is simply turned in the opening direction, Interference between these makes it impossible to open the valve.

On the other hand, when opening the safety cap 100 from the container 200, the operation opposite to the above state transition may be actively performed.
That is, when opening the cap, the user first turns the safety cap 100 in the opening direction while pressing the plurality of movable panels 30 with the correct combination of pressures. More specifically, in this embodiment, the safety cap 100 is turned in the opening direction while pressing the lower side of the connecting part 31 on the first movable panel 30A and the upper side of the connecting part 31 on the second movable panel 30B. .

In this way, when both the first movable panel 30A and the second movable panel B are pressed in parallel so that the heights in the axial direction are staggered, the engaged portion 40 of the first movable panel 30A (one The engaged portion 40 of the second movable panel 30B (the other engaged portion) moves 210 inches _inward from the engaging portion 210, and the engaged portion 40 (the other engaged portion) of the second movable panel 30B moves 210 inches _outward from the engaging portion 210. do. As a result, the engaged part 40 is disengaged from the same circumference as the engaging part 210 in conjunction with the pressing of each movable panel, and the engaged part 40 and the engaging part 210 are disengaged. The bottle is ready to be opened.
At this time, as is clear from FIG. 10(β), the state in which at least two movable panels 30 are pressed and tilted is not symmetrical about the axis (θz direction) (in the embodiment, the state is not symmetrical about the axis (θz direction). It is not symmetrical (it is rotated 180° around the axis and is asymmetrical). That is, in the description on the left, the first movable panel 30A is axially moved around the connecting portion 31 as a fulcrum such that the upper area UA (see FIG. 4) is farther away from the inner peripheral wall 50 than the lower area DA. It will be in a leaning state. On the other hand, the second movable panel 30B is tilted in the axial direction with the connecting portion 31 as a fulcrum such that the upper area UA (see FIG. 4) is closer to the inner peripheral wall 50 than the lower area DA. becomes. Therefore, if the first movable panel 30A in this tilted state is moved around the axis to the position of the second movable panel 30B, the tilted states of the two will not match and will be in a crossed state with the connecting portion 31 as the center. .

The safety cap 100 and container 200 (container unit with cap CU) of this embodiment described above can provide the following effects.
In other words, when closing a container, it is impossible to open the container even if the movable panel 30 is pressed in a manner other than the above-mentioned combination of correct pressing heights, which greatly reduces the possibility of children or the like accidentally opening the container. Ru. On the other hand, if the movable panel 30 is pressed in the correct combination, it is possible to perform the opening operation without making it too complicated. In addition, since the safety cap 100 of this embodiment does not have a two-piece structure, it is possible to suppress an increase in cost due to an increase in the number of parts.

Note that the embodiment described above is an example, and various modifications can be made without departing from the spirit of the present invention.
For example, in the embodiment described above, the number of engaged parts 40 in the safety cap and the number of engaging parts 210 in the container 200 are made to match (two each in the above example), but each has at least two If there are more than one, the configuration may be such that the numbers do not match each other.

In addition, the connecting positions of the pair of movable panels 30 are both at the center of the outer peripheral wall 20, but in addition to providing connecting parts at the upper and lower ends as described above, for example, one connecting part is at the upper edge and the other connecting part is at the upper edge. They may be combined as appropriate, such as at the lower end, or with one connecting portion at the center and the other connecting portion at the upper or lower end.

INDUSTRIAL APPLICATION This invention is suitable for providing the safety cap with the child resistance function which also has an improved safety function at low cost.
