And this plastic cap is stoppered to make it liquid-tight by plugging it into the mouth of the container, and further maintains a liquid-tight state so that it does not come off easily.In addition, a tamper-evidence mechanism is provided, and when the upper lid is opened, The fact remains, and most of them are designed to prevent various mischiefs. In addition, since this plastic cap is made of a material different from that of the container and is kept from being easily removed from the mouth of the container in order to maintain a liquid-tight state, various measures have been taken to improve separation and disposal. ing. The following are known as general shapes of such easily separable plastic caps.

Utility Model Registration No. 2589034 Japanese Utility Model Publication No. 7-846 JP 2001-97431 A

As shown in FIG. 11, the easily separable plastic cap of Patent Document 1 is plugged into the small diameter portion b at the tip of the mouth portion a of the container and has a dispensing cylinder c, and the cap body d.
A lower cylinder g having a weakening line and a knob f for connecting and breaking to the outer peripheral edge of the lower end of the outer cylinder of the outer cylinder and a large-diameter screw part h below the tip small-diameter part b of the container mouth part a. And the upper cover i to be attached / detached, and at the time of sorting and discarding, the weakening line is broken by the knob f and the weakened part e is also broken, and the lower cylinder g is separated from the outer peripheral edge of the lower end of the outer cylinder of the cap body d If the bottle opener is hung between the bottom of the outer cylinder of the main body d and the bottom of the dispensing cylinder c, the cap main body d can be easily removed from the mouth part a of the container.

As shown in FIG. 12, the easily separable plastic cap of Patent Document 2 is a cap main body d1 that is plugged into the mouth portion a of the container and has a dispensing cylinder c and a screw peripheral wall j on the outside thereof, and the cap main body d1. A lower cylinder g having a weakening line and a knob f connected to the outer peripheral edge of the lower end of the outer cylinder at the weakened portion e, and an upper lid i1 which is screwed into and removed from the screw peripheral wall j of the cap body d1;
When sorting and discarding, the weakening line e is broken by the knob f and the weakened part e is also broken,
If the lower cylinder g is cut off from the outer peripheral edge of the lower end of the outer cylinder of the cap main body d1, and the bottle opener is hung between the lower outer cylinder of the cap main body d1 and the lower part of the extraction cylinder c, the cap main body d1 can be easily removed from the mouth part a of the container. It can be removed.

As shown in FIGS. 13 and 14, the easily separable plastic cap of Patent Document 3 includes a cap body d <b> 2 including a cylindrical portion k, a dispensing cylinder c, a blocking wall l, a score m, and a pull ring n. ,
And an upper lid i2 that is screwed into and removed from the cap main body d2, and a tearing knob f is erected above the separation base end portion of the cylindrical portion k located concentrically outside the dispensing cylinder c. The part k has a circumferential slit part o at the inner side of the separation base end part, a longitudinal weakening line continuous to one end of the circumferential slit part o, and a circumferential direction continuous to the other end of the circumferential slit part o. A weakening line is formed and the upper lid i2 is completely covered except for the outer peripheral skirt of the cylindrical portion corresponding to the knob margin of the cap body d2. Alternatively, if it is engaged with the tearing knob f and pulled to the front, the longitudinal direction weakening line is cut first, and then the finger f is pulled in the circumferential direction with the fingers, the circumferential direction weakening line is also cut off from the container mouth a. Cap body d2 can be easily removed A.

After separating the lower cylinder g from the cap body d by the knob f, the easily separable plastic cap of Patent Document 1 does not open the bottle between the bottom of the outer cylinder of the cap body d and the bottom of the extraction cylinder c. Since the cap body d cannot be removed from the mouth part a of the container, a bottle opener is required and is troublesome. Further, the container must have a special shape in which the mouth portion a is formed by the tip small-diameter portion b and the large-diameter screw portion h therebelow. In addition, since it is easy to remove the top lid i from the mouth part a of the container, there is a possibility that the unauthorized opening person can contaminate the extraction tube c and tamper with the worst contents.

In addition, the easily separable plastic cap disclosed in Patent Document 2 has a cap body d by a knob f.
Since the cap body d1 cannot be removed from the mouth part a of the container unless the bottle opener is hung between the bottom of the outer cylinder of the cap body d1 and the bottom of the extraction cylinder c after separating the lower cylinder g from 1. Again, it requires a bottle opener and is troublesome. In addition, there is a large space between the cap body d and the upper lid i, and the contents hanging down from the dispensing cylinder c are likely to accumulate there, and the contents are altered to cause various inconveniences. In addition, since it is easy to remove the top lid i1 from the mouth part a of the container, there is a possibility that the tampered opener can contaminate the extraction tube c and tamper with the worst contents.

Furthermore, in the easily separable plastic cap of Patent Document 3, the convex portion p of the upper lid i2 is engaged with the circumferential slit portion o or the tearing knob f, or the knob f is directly pulled forward with fingers. First, cut the longitudinal weakening line, and then pull the knob f in the circumferential direction with your fingers.
The circumferential weakening line is also cut. However, since the cylindrical portion k of the cap body d2 has considerable rigidity and the circumferential weakening line must be cut at the same time, the cylindrical portion k can be cut unless the knob f is pulled in the circumferential direction with a considerable force with fingers. Actually, it is difficult to remove the cap body d2 from the mouth part a, and there is a possibility that the fingers are cut by the burr after cutting. On the other hand, since it is easy to remove the upper lid i2 from the mouth part a of the container, there is a possibility that the unauthorized opening person may contaminate the extraction cylinder c and tamper the worst contents.

Therefore, an object of the present invention is to prevent contamination of the dispensing cylinder directly touching the contents and tampering of the contents, and the contents hanging from the dispensing cylinder do not collect in the cap, and from the mouth of the container at the time of disposal. It is an object of the present invention to provide an easily separable plastic cap that can be easily separated and can improve the separation waste.

The present invention has been proposed in order to achieve the above object, and is characterized by having the following configuration.

Rotating synchronously in the wearing direction, providing a cap body side ratchet on the outer peripheral surface of the cap body, providing a band side ratchet on the inner peripheral surface of the band, and expanding the diameter when the cap body is plugged into the mouth Thus, the easily separable plastic cap is provided in which the cap main body side ratchet is set so as to wrap around the band side ratchet, and further, the falling space of the band after breaking the connecting rib is secured around the cap main body.

According to the present invention, the upper lid is directly screwed into and removed from the dispensing cylinder of the cap body, and the generation of wrinkles due to the remaining contents is eliminated by eliminating the space for the contents to accumulate between the cap body and the upper lid. Can be prevented in advance. Also, after breaking the weak part with the notch knob and notching the stopper part of the cap body, the cap body can be detached from the mouth of the container, and once opened by the tamper evidence mechanism between the top lid and the band The fact remains, and the fact of unauthorized opening is revealed at a glance. As a result, the cap body can be easily separated from the mouth of the container at the time of disposal, and the separation and disposal can be improved, and in addition, contamination such as a dispensing cylinder directly touching the contents and falsification of the contents can be prevented. effective.

In addition, by providing a hollow portion in the pour tube of the cap body, even if the pour tube is made thick, there is no need to use extra material, and the weight can be reduced.

Furthermore, by making the notch knob into a gate type, that is, a gate shape, it is easy to grasp with fingers, and it is very easy to break the fragile part and discard the stopper part of the cap body when discarding the container. .

Moreover, according to the structure of Claim 4, the cap main body side ratchet is wrapped on the band side ratchet using the enlarged diameter of the cap main body when the cap main body is plugged into the mouth portion of the container, The upper lid can be smoothly screwed onto the cap body, and if the upper lid is screwed off from the cap body after being tapped, the tamper-evidence mechanism works and the tether rib is broken and the band falls into the drop space. Even if the accuracy is low, the object can be achieved and the tampering can be recognized at a glance.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

The container 3 is not particularly limited as long as the above-described easily separable plastic cap 1 can be plugged into the mouth part 4, and a normal container material such as polyethylene, polypropylene, or polyethylene terephthalate is used. In this embodiment, a bottle-type plastic container such as polyethylene terephthalate, which is frequently used for edible oil, seasonings, and the like and that has a relatively large number of open / close stoppers by the upper lid 8 is assumed.

The easily separable plastic cap 1 is made of a plastic material different from that of the container 3, and as described above, the cap body 7, the upper lid 8 screwed to the cap body 7, and the tamper evidence between them. It consists of a band 10 with a mechanism 9 interposed. The cap body 7 is
An inner ring 20 and a skirt portion 21 are provided under the top plate 2 to form the plugging portion 5, and the mouth portion 4 of the container 3 is plugged into the opening 22 of the plugging portion 5 so as to be liquid-tight. And The pouring cylinder 6 is erected on the top plate 2 of the cap main body 7, and the upper lid 8 is screwed on and off by screws engraved on the outer surface of the pouring cylinder 6. Further, a hollow portion 23 is provided in the pouring tube 6, and reinforcing ribs 24 are provided at important points of the hollow portion 23 to reinforce the pouring tube 6. Therefore, in order to prevent the contents hung from the pouring cylinder 6 from being accumulated by screwing the upper lid 8 on the pouring cylinder 6 of the cap body 7 so as to prevent accumulation, the hollow portion 23 is used to make the pouring cylinder 6 thick. The molding material can be reduced and the weight can be reduced.

A pouring hole score 25 is provided in the top plate 2 located at the bottom of the pouring cylinder 6, and a pull ring 26 is attached to the top plate 2 surrounded by the pouring hole score 25. Therefore, by pulling and pulling the pull ring 26 with fingers, the pouring hole score 25 can be broken and opened, and the contents of the container 3 can be poured out from the pouring cylinder 6. At that time, even if the contents poured out from the pouring cylinder 6 may hit the outer surface of the pouring cylinder 6, the top plate 2 and the skirt 2
It is possible to prevent the occurrence of wrinkles due to the remaining contents without causing the liquid to accumulate only by flowing over the first.

The cap body 7 is provided with a sorting and discarding function. In this embodiment, the sorting and discarding function, as shown in FIGS. 2, 4, and 5, the top plate 2 constituting the stopper portion 5 and the skirt. The fragile portion 11 is formed by cutting out a part of the fragile portion 11 over the portion 21, and the fragile portion 11 is further provided.
The notch knob 12 having a gate shape is provided on the top plate 2 surrounded by and cut out. The fragile portion 11 is broken by the gate-shaped notch knob 12 and the top plate 2
Further, by separating a part of the skirt portion 21 and removing the cap body 7 from the mouth portion 4 of the container 3, it is possible to facilitate separation and disposal. Further, when the upper lid 8 is screwed onto the dispensing cylinder 6 of the cap body 7 and the upper lid 8 is kneaded with the cutout portion 5 facing upward, the cap body 7 together with the upper lid 8 is obtained.
Can be easily removed from the mouth portion 4 of the container 3 to separate the container 3 from the upper lid 8 and the cap main body 7, which also enables recycling or separation and disposal as it is. The notch knob 12 has a gate shape and is easily grasped with a finger, but is not limited to this shape, and may be a plate shape, for example.

In this embodiment, the planar cutout portion is removed by the two weakened portions formed in the vertical direction on the leg portion of the gate of the cutout knob 12, but in addition, For example, as shown in FIG. 6, one skirt portion 21 is connected to the skirt portion 21 in the longitudinal direction and one circumferential weak portion 11 is formed on the top plate portion, and the cap body is folded in the longitudinal direction and the circumferential direction. The sorting and discarding function can also be realized by cutting into a shape.

The upper lid 8 is formed by a top plate 30 and the outer peripheral wall 14 following the periphery thereof. The screw peripheral wall 13 and the inner ring 31 are provided concentrically on the inner surface of the top plate 30. The inner ring 31 is screwed into and removed from the pour tube 6 of the cap body 7, and the pour tube 6.
The inside of the outer peripheral wall 14 is prevented from leaking, and a non-slip 32 is provided on the outer periphery of the outer peripheral wall 14 so that the cap body 7 can be easily screwed on and off. When the upper lid 8 is screwed onto the cap body 7, the notch knob 12 on the top plate 2 of the cap body 7 is positioned between the outer peripheral wall 14 and the screw peripheral wall 13 of the upper lid 8 to guard this. doing. The upper lid 8 is connected to the band 10 below the upper lid 8 by the tamper evidence mechanism 9 so as to be integrated. The band 10 has a ring shape and is in a position covering the skirt portion 21 of the cap body 7.

A tamper evidence mechanism 9 is interposed between the upper lid 8 and the band 10 below the upper lid 8.
The tamper evidence mechanism 9 is as follows.
That is, the tamper evidence mechanism 9 connects the upper lid 8 and the band 10 below the upper lid 8 with an easily breakable connecting rib 33 and provides the stoppers 34 on the upper lid 8 and the band 10 to synchronize them in the screwing direction. The cap main body side ratchet 35 is provided on the outer peripheral surface of the cap main body 7 and the band side ratchet 36 is provided on the inner peripheral surface of the band 10.
The cap body side ratchet 35 is set so as to wrap around the band side ratchet 36 due to the diameter expansion of the cap body 7 when the container 3 is plugged into the mouth 4 of the container 3, and the band 10 falls after the joining rib 33 breaks. A space 37 is secured around the cap body 7.

Therefore, first, it is necessary to screw the upper lid 8 integrally formed with the band 10 to the cap body 7, and the stopper ribs on the lower end surface of the upper lid 8 and the upper end surface of the band 10 so as not to break the connecting rib 33. When the upper lid 8 is screwed to the cap body 7 when the upper lid 8 is screwed, that is, when the upper lid 8 is rotated in the clockwise direction, the stoppers 34 come into contact with each other and can be screwed without applying a load to the connecting rib 33 without breaking. .

However, when the upper lid 8 is unscrewed from the cap body 7, the band 10 is not attached to the cap body 7.
Since only the upper lid 8 needs to be screwed to the side, a band side ratchet 36 is provided on the inner peripheral surface of the band 10, and a cap main body side ratchet 35 is provided on the outer peripheral surface of the cap main body 7.
As shown in FIG. 8, the positional relationship between the ratchets 35 and 36 is such that the band 1
In the state where the upper lid 8 integrated with 0 is screwed, it does not wrap (it may be slightly wrapped if there is no problem with the screwing), and the cap body 7 is connected to the mouth of the container 3 as shown in FIG. The cap main body side ratchet 35 also bulges outward due to the diameter expansion of the cap main body 7 when it is plugged into 4, and is set to wrap around the band side ratchet 36 by an H dimension.

That is, since the upper lid 8 integrated with the band 10 is first screwed into the cap body 7 and then plugged into the mouth portion 4 of the container 3 in that state, the cap body side due to the diameter expansion of the cap body 7 at that time It is possible to use the outward bulge of the ratchet 35. Therefore, when the upper lid 8 is unscrewed from the cap body 7 (when it is turned in the direction of the arrow in FIG. 10, that is, counterclockwise), the cap body side ratchet 35 and the band side ratchet 36 are wrapped by the H dimension. 10, the band side ratchet 36 is the cap body side ratchet 35.
The band 10 cannot move and the connecting rib 33 is broken. Then, the broken band 10 falls into the drop space 37 by the dimension H1 until the cap main body side ratchet 35 and the collar part on the upper part of the band 10 contact each other, so that the fact of tampering is clearly determined at a glance.

In addition, several racks 38 are provided on the upper surface of the band 10 with a slight gap from the upper lid 8, and the band 10 and the upper lid 8 are integrally configured, and are further screwed to the cap body 7, and the container 3. The linking rib 33 is prevented from being broken at the mouth portion 4 in the stoppered state, and is supported by a rack 38 with respect to an external force in the vertical direction so that the external force is not applied to the linking rib 33.
1 and 5, reference numeral 39 denotes a detent provided on the cap body 7. When the upper lid 8 integrally formed with the band 10 is screwed onto the cap body 7, the cap body 7 is secured by the band 10 and the upper lid 8.
Since it will be difficult to fix it, it will be difficult to fix.
The cap body 7 is prevented from being rotated, and the upper cover 8 having an integral structure can be smoothly screwed onto the cap body 7.

Next, a method of using the easily separable plastic cap 1 having the above configuration will be described.
The upper lid 8 integral with the band 10 is screwed onto the cap body 7 in advance, and a jig is applied to the detent 39 of the cap body 7, and the upper lid 8 integral with the band 10 is applied to the dispensing cylinder 6. When the cover is turned clockwise, the stoppers 34 of the upper lid 8 and the band 10 are immediately brought into contact with each other, and the cap body 7 is not rotated by the rotation stopper 39 and can be screwed to the cap body 7 without applying a load to the connecting rib 33. Then, the container 3 is filled with the contents, and the mouth 4 of the container 3 is plugged into the inner ring 20 of the cap body 7 and the opening 22 of the skirt portion 21 of the easily separable plastic cap 1. The inside is liquid-tight to make the final product.

When consuming this product, at least the part of the easily separable plastic cap 1 is bare and the upper lid 8 is unscrewed from the cap body 7 with fingers using the anti-slip 32 of the upper lid 8, that is, turned counterclockwise. Since the cap main body side ratchet 35 and the band side ratchet 36 are wrapped by an H dimension, the band 10 does not move, and if the upper lid 8 is rotated counterclockwise, the connecting rib 33 is broken and the upper lid 8 is screwed. The contents can be removed from the container 3. At this time, even if the liquid runs out poorly and the content hangs down from the pouring cylinder 6 to the outer surface, it does not accumulate only by flowing over the top plate 2 and the skirt portion 21. Further, if the contents remain in the container 3, the upper lid 8 can be screwed again into the mouth portion 4, and the storage becomes easy. On the other hand, since the broken band 10 is dropped in the drop space 37, if the above-described screwing is illegally opened, the legitimate opener visually observes that the band 10 is dropped in the drop space 37. , The fact of tampering can be recognized immediately and clearly, and danger can be avoided easily.

When the contents in the container 3 are used up, the band 10 is first moved upward with the top cover 8 removed from the mouth 4 in order to separate and discard the container 3 and the easily separable plastic cap 1 made of a different material. Pull out, grasp the notch knob 12, break the fragile portion 11, cut out the stopper portion 5 of the cap body 7, that is, a part of the top plate 2 and the skirt portion 21, and cap from the mouth portion 4 of the container 3 as it is. Remove the body 7. Alternatively, when the upper lid 8 is screwed onto the dispensing cylinder 5 of the cap body 7 and the cut-out portion is kneaded upward, the cap body 7 can be completely separated from the mouth 4 of the container 3 together with the upper lid 8, There is no pain. Therefore, it is possible to remove the cap main body 7 and the band 10 loosely fitted to the upper lid 8 from the mouth 4 of the container 3 without using tools, and it is possible to remove the separation waste. Can be raised.

As mentioned above, although the Example of this invention was described, it should be understood that a concrete structure is not limited to this, and the change in the range which does not deviate from the summary of this invention is possible suitably.

The easily separable plastic cap of the present invention is effective when it is required to be separated and disposed of with the container, and is required to have a function of preventing the contamination of the part directly touching the contents and the alteration of the contents. For example, it is particularly useful for vinegar and the like that easily change in quality, and in such a case, the applicability becomes extremely high.
