Description

The present invention provides a container for storing food and drinking water, during the capping relates wash system in the wash the contents adhering spilled near the mouth portion, in particular a composite container closure plug middle and the cap body are combined It relates washing system suitable vessel equipped with.

A wide variety of beverages such as juices and soft drinks, seasonings and edible oils, and products packed in containers such as jams and prepared dishes are available. When the contents are food, a large amount of air in the head space causes deterioration, so a method of filling the container as much as possible to reduce the head space as much as possible may be employed. After filling, the container is sealed in the capping process, but the filled contents may be scattered around the container mouth and neck and become attached. Dirty or rot will cause hygiene problems. For this reason, cleaning after capping is required, but cleaning is simple if only the outer surface of the container and the lid, but the container mouth neck portion and the screwing portion provided with the spiral portion are formed. It is also necessary to clean the inside of the lid skirt. It is extremely inconvenient for the consumer to get this part dirty when opening the lid, and the product is not reliable in terms of hygiene.
Therefore, a cleaning liquid permeation means that may be a through slit or a hole is formed at the upper part of the skirt wall of the container lid and / or the peripheral part of the top wall, and the container neck is attached to the mouth and neck part of the container body so that the mouth and neck part is attached. After sealing, spraying the cleaning liquid toward the container lid, allowing the cleaning liquid permeating means to permeate, and entering between the outer peripheral surface of the mouth neck of the container main body and the inner peripheral surface of the skirt wall of the container lid, It has been proposed to wash away the contents scattered and adhered to the outer peripheral surface of the mouth and neck, and also the contents transferred from the outer peripheral surface of the mouth and neck to the inner peripheral surface of the skirt wall of the container lid.

  Such a conventional cleaning method is performed by a method as disclosed in Patent Document 1, for example. This method is for a lid body in which a cleaning liquid permeation means comprising a plurality of fine cuts penetrating from the outer surface to the inner surface of the skirt wall is formed on a resin container lid. First, the container lid is heated to 70 ° C. or higher, and then 45 By injecting the cleaning liquid heated to 70 ° C., the cleaning liquid permeating means is permeated and the cleaning liquid is allowed to enter between the outer peripheral surface of the mouth / neck portion of the container and the inner peripheral surface of the skirt wall of the container lid. This achieves the required cleaning. By heating the container lid to 70 ° C. or higher and then spraying the cleaning liquid heated to 45 to 70 ° C., the cleaning liquid permeating means can be improved in the cleaning liquid even when the incision constituting the cleaning liquid permeating means is sufficiently small. The reason for the penetration is that when the temperature of the container lid is raised, the notch is expanded due to thermal strain, and the container lid expands somewhat, which causes the mouth and neck of the container body and the container lid to expand. The air pressure in the space between the skirt wall is reduced, the cleaning liquid is sucked through the cleaning liquid permeation means due to the reduced pressure, and the surface tension of the cleaning liquid becomes smaller as the temperature of the cleaning liquid becomes higher, and the cleaning liquid permeation means It is also understood that once the flow path is formed, the subsequent cleaning liquid is continuously drawn by the siphon action. .

  Moreover, when opening the container in which the contents are packed in a positive pressure state, there arises a problem that the positive pressure gas blows out the contents. As a solution to this problem, Patent Document 2 discloses a composite container lid. This composite container lid is a lid having a structure in which a cap main body (outer lid) and an inner plug (inner lid) fitted to the center portion thereof are combined. When the container lid is opened, the inner lid is shown in FIG. 9 showing the engagement state between the container lid and the container mouth portion regardless of the degree of screw engagement between the cap body 1 and the container mouth portion 10. At the same time as the sealing of the packing 3 of 2 and the tip of the container opening 10 is released, a gas flow path as shown by the arrow in FIG. It is possible to perform degassing. Troubles such as blowing out the contents at the time of opening and flying of the container lid are effectively prevented.

The present applicant provides a composite cap that can be opened with an appropriate torque so as not to cause over-tightening and to have high sealing performance, and to provide a composite cap having such advantages. The purpose of the present invention is to provide a composite cap that is easy to clean in order to eliminate problems such as foreign matter caught in the joint portion between the inner plug and the cap body, which is a structural problem of the composite cap. -39821 "Composite Cap" is presented. In order to achieve this object, the composite cap according to the invention covers the top surface of the mouth 10 of the container as shown in FIG. 7 which is a cross-sectional view of the state where the container is mounted on the container and FIG. A synthetic resin inner plug 2 having a top panel 2a, a synthetic resin cap body 1 having an annular wall 1a covering the peripheral edge of the inner plug 2, and a cylindrical skirt portion 1b hanging from the peripheral edge of the annular wall; The inner cap 2 is formed with a first locking projection 2b extending upward from the vicinity thereof along the outer peripheral edge of the inner cap 2 and a sealing portion for sealing the container mouth portion on the lower surface 2c, and the cylindrical skirt portion 1b of the cap body 1 has a female thread 1c that engages with a male thread 11 on the outer periphery of the container mouth on the inner peripheral surface, and from the lower surface of the annular wall 1a. A second locking projection 1d is formed, which is closed In the outer peripheral surface of said inner peripheral surface of the first locking protrusion 2b second locking protrusion 1d is characterized in that the engaged.

Power saving can be achieved.

  The composite container lid cleaning method of the present invention is intended for a container sealed with a composite lid comprising an outer peripheral shell 1 as a cap body and a top panel 2 as an inner plug. As can be seen from FIGS. 5 and 6, this composite container has a cap body comprising a cylindrical lid skirt 1b and a cap body top surface annular wall 1a extending inward from the upper end of the lid skirt 1b. An opening is formed inside 1a. The inner plug is formed so that the outer peripheral portion of the inner plug is located on the upper surface of the container neck and the lower surface of the annular wall 1a and the central portion covers the opening in the state where the composite lid is capped. At least one of the inner surface of the annular wall 1a and the inner peripheral portion of the inner plug is provided with a flow path 1e formed of a rib or groove disposed in the circumferential direction. As described above, the spilled contents remain attached to the region between the container mouth portion 10 and the lid skirt portion 1b that has been filled and capped with the contents. It can become dirty or rot and cause hygiene problems. Therefore, in the present invention, cleaning water is jetted from above to clean the contaminated area from the top panel 2 through the channel 1e formed of ribs or grooves, and the cleaning water remains in the area and is dried and soiled. It is conceived that air is blown to remove the washing water and dry it so as not to attach rust or rust the metal member.

  The basic configuration of the composite container lid cleaning system of the present invention is as shown in FIG. That is, in the line for filling and capping the container 5 using the composite lid composed of the outer peripheral shell 1 as the cap body and the top panel 2 as the inner plug, the container opening is opened from the top panel 2 portion following the capping step. This is a container mouth cleaning system in which means 6 for supplying cleaning water under pressure is arranged between the neck 10 and the inner surface of the lid skirt 1b. One form of the present invention employs a form in which cleaning water is pressurized and forcedly supplied to the gap between the cap body 1 and the inner plug 2. For this reason, cleaning can be effectively executed in a short time. In the form in which cleaning water is pressurized and forcibly supplied, an annular seal member 7 such as an O-ring that makes a circular sealed space 6b in contact with the cap body annular wall 1a of the container 5 to be conveyed is provided at the end surface, and is provided at the central portion. Is formed with a supply path 6a connected to a supply source of washing water, and more preferably, the end face of the circular sealed space 6b surrounded by the annular seal member 7 is formed of a perforated plate 6c formed with a number of flow holes. Yes.

  When the cleaning water supply means 6 having such a configuration is installed at the subsequent stage of the capping process of the line and the container after the capping is conveyed, the cleaning water supply means 6 is driven to be displaced so as to come into contact with the top surface of the cap. Then, the annular seal member 7 is brought into pressure contact with the cap main body annular wall 1 a of the container 5. By this contact, a circular sealed space 6 b is formed between the top of the cap and the end of the cleaning water supply means 6. In this state, cleaning water is pressurized and supplied to the circular sealed space 6b from a supply source (not shown) via the supply path 6a. Wash water under pressure in the circular sealed space 6b passes from the gap 4 between the outer shell 1 and the top panel 2, which is an inner plug, to the bottom of the cap via the container neck portion 10 and the inner surface of the lid skirt 1b. Is discharged to the outside. By this forced flow of the washing water, the contents attached between the container neck portion 10 and the inner surface of the lid skirt 1b are washed and discharged all at once. In the embodiment of the present invention using pressurized washing water, effective washing is performed in a short time by a forced flow by pressurized supply of washing water.

  As a preferred embodiment of the present invention, a container mouth cleaning system is provided in which means for supplying air between the top panel portion and the inner surface of the container mouth neck and the inner surface of the lid skirt is arranged following the means for supplying cleaning water in the line. Even if the contents adhering to the washing water are washed and discharged, a part of the washing liquid remains between the container neck and the inner surface of the lid skirt, and it remains dry and soils the surface of the part. When the consumer opens the container, if the threaded part of the neck of the container mouth is dirty, it will cause a sense of filth and trust the product. In order to prevent this, after washing with washing water, compressed air is supplied to forcibly discharge remaining washing water, and the washing water flow passage is dried with air. The structure of the air supply means may be basically the same as that of the washing water supply means 6 described above. However, the difference is that what is supplied from the supply source is not compressed water but compressed air.

  When the air supply means having such a configuration is installed at the latter stage of the line cleaning process and the container after cleaning is conveyed, the air supply means is placed on the top of the cap in the same manner as the previous cleaning water supply means 6. The displacement seal drive is carried out so as to contact, and the annular seal member 7 is pressed against the cap body annular wall 1a of the container 5. This contact forms a circular sealed space between the top of the cap and the end of the air supply means. In this state, air is pressurized and supplied to the circular sealed space from a supply source (not shown) via a supply path. Washing water under pressure in this circular sealed space passes from the gap 4 between the outer shell 1 and the top panel 2 that is the inner plug from the bottom of the cap via the container neck and the inner surface of the lid skirt 1b. It is discharged outside. By the forced flow of the compressed air, the washing water remaining and adhered between the container neck 10 and the inner surface of the lid skirt 1b is discharged at a time and the flow passage is dried. In this embodiment, the cleaning water is effectively discharged and dried in a short time with a forced flow of pressurized air supply.

  Next, an installation form of the container mouth part cleaning system according to the present invention in the container filling / capping process line will be described. In the form shown in FIG. 2, the washing water supply means and the compressed air supply means are sequentially arranged in the conventional line following the capping step. That is, when the empty container 5 has been transported by the transport means 8, a first turret T1 is disposed, and a filling machine is installed in the turret T1 to fill the contents. Subsequently, the container 5 filled with the contents by the transport means 8 is transported to the second turret T2. The second turret T2 is provided with a capper, which is covered with a cap and sealed. At this stage, the sealing material on the top of the mouth of the container 5 and the inner surface of the top of the cap is in pressure contact, ensuring that the container is sealed and spilled between the neck of the container mouth and the inner surface of the lid skirt. There may be a state where an object is attached. After the capping step, first, the cleaning water supply means 6 is arranged on the line, and when the container 5 that has been filled and capped by the transport means 8 is transported, the end surface of the cleaning water supply means 6 becomes the cap top. The displacement seal drive is performed so as to contact the surface, and the annular seal member 7 is pressed against the cap body annular wall 1 a of the container 5. By this contact, a circular sealed space 6 b is formed between the top of the cap and the end of the cleaning water supply means 6. In this state, washing water is pressurized and supplied to the circular sealed space 6b from the supply source (not shown) via the supply path 6a, and the contents spilled and adhered between the container neck and the inner surface of the lid skirt in the above-described operation. Wash things. Subsequently, the compressed air supply means 6 ′ is arranged at the rear stage of the line, and when the container 5 cleaned by the transfer means 8 is transferred in the same manner as the operation of the cleaning water supply means 6, the end surface of the compressed air supply means 6 ′. Is displaced to come into contact with the top surface of the cap, and the annular seal member 7 is brought into pressure contact with the cap body annular wall 1a of the container 5. This contact forms a circular sealed space 6 'between the top of the cap and the end of the compressed air supply means 6'. In this state, compressed air is supplied to the circular sealed space 6b through a supply path 6a from a supply source (not shown) and remains between the container neck and the inner surface of the lid skirt by the above-described operation. The washing water is forcibly removed and the part is dried.

  This first embodiment is the simplest arrangement of the container mouth cleaning system according to the present invention, and is a simple facility that simply adds cleaning water supply means 6 and compressed air supply means 6 'to the conventional system. Since it can be implemented with changes, the burden of capital investment will be very light. In the first place, although the cleaning means of the present invention enables processing for a short time, it is difficult to instantaneously perform the operation of cleaning the contents by bringing the end surface of the cleaning water supply means 6 into contact with the top surface of the cap. When the speed is high, it is necessary that at least this part of the conveying means 8 is in an intermittent operation mode or the cleaning water supply means 6 is in a displaceable mode. The same applies to the compressed air supply means 6 '. A second embodiment that solves this problem is shown in FIG.

  In the second form, the line up to the capping step is exactly the same as the previous form, and the difference is that the cleaning water supply means 6 and the compressed air supply means 6 'are not on the line conveying means 8 but on the third turret. This is the point where T3 is arranged and performed at that portion. By adopting this configuration, cleaning with cleaning water is performed in the first half of the operation of the turret T3, and residual cleaning water is removed and dried with compressed air in the second half. If it is this form, each work time can fully be ensured, without reducing the speed of a line. Moreover, it is not necessary to make a big change to the conventional equipment in terms of equipment, and it is possible to cope with the problem by simply adding the third turret T3. The washing water supply means 6 and the compressed air supply means 6 'may be simply and separately arranged in series. However, the washing water supply means and the compressed air supply means are structurally the same except that the supply sources are different. In this embodiment, it is reasonable to arrange the switching mechanism so that the cleaning water / compressed air supply means 16 is used for switching and supplying the cleaning water supply source and the compressed air supply source in time series. First, wash water is supplied, and then compressed air is supplied. When this configuration is adopted, when the washing water / compressed air supply means 16 is driven to come into contact with the top surface of the cap and the annular seal member 7 is pressed against the cap body annular wall 1a of the container 5, this contact is compressed. It is possible to continue to the air supply. In short, since the displacement drive of the supply means that must be repeated twice can be done once, labor can be saved in terms of time and energy.

  FIG. 4 shows a third embodiment. In this embodiment, cleaning with cleaning water performed at the third turret T3 and removal / drying of residual cleaning water with compressed air are performed collectively in the second turret T2 of the capping step. This form does not require the third tarrate T3 and the accompanying cleaning water supply means 6 or compressed air supply means 6 ', but the role of the cleaning water supply means 6 and compressed air supply means 6' in the capping mechanism. In order to use them together, a special capping mechanism as described later is required. The conventional capping mechanism performs the work of gripping the cap and fitting the cap to the mouth of the filled container and tightening it. In this embodiment, subsequent to the work, cleaning with cleaning water and residual cleaning water with compressed air are performed. In order to cause the capping mechanism to execute exclusion and drying, an end surface is provided with an annular seal member 7 such as an O-ring that forms a sealed space 6b, and a supply path connected to a supply source of cleaning water / compressed air in the central portion The one formed with 6a is required. When this embodiment is adopted, the equipment can be realized more compactly than the second embodiment, and the cleaning liquid and the air can be supplied in addition to the capping in one operation with respect to the driving of the pressure contact mechanism. Further time reduction and power saving can be achieved.

An example of the cleaning water / pressed air supply means 16 of the composite container lid cleaning system of the present invention employed in the second embodiment shown in FIG. 3 will be described with reference to FIG.
In this embodiment, a sealing material 3 is fitted into a cap main body (outer peripheral shell) 1 such as PET and the annular groove of a metal disc such as a tin plate having a peripheral edge portion formed into an annular groove and an edge portion curled. Further, the present invention is applied to a container using a composite lid composed of the inner plug 2. The outer peripheral shell 1 of the composite lid is formed in a comb-like shape at the end face of the annular wall 1a as shown in the figure, and a space between the comb teeth is opened to form a flow path 1e leading to the skirt portion 1b. The tip of the comb teeth comes into contact with the top surface of the annular groove of the inner plug 2, and when the male thread 11 of the container and the female thread 1c of the cap skirt are screwed together, the top surface of the container mouth 10 is The sealing material 3 of the inner plug 2 is pressed against each other, and the container 5 is sealed. Since the outer shell 1 and the inner plug 2 are separated, the composite lid is sealed. Therefore, even when the tamper-evident mechanism is turned slightly, the outer shell 1 is slightly closed. By simply rotating, the sealing between the top surface of the container mouth 10 and the sealing material 3 of the inner plug 2 is ensured, and the safety can be ensured.

  In this embodiment, the container capped with this composite lid is washed. However, if the container 5 that has been filled and capped has been transported to the third turret T3, washing water / squeezing is performed. The air supply means 16 is displaced in the container direction, and the cleaning water supply means 6 presses the annular seal member 7, which is an O-ring, from above the annular wall 1 a of the outer shell 1 as shown in FIG. This displacement drive mechanism is operated in synchronism with the conveyance of the container. At the timing when the O-ring 7 is brought into pressure contact with the annular wall 1a of the outer shell 1 and the sealed space 6b is formed in the region surrounded by the annular seal member 7, the washing water is first pressurized and supplied to the supply passage 6a. The The supplied cleaning water is sprayed to the top surface portion of the inner plug 2 through the flow holes of the perforated plate 6c in which a large number of flow holes are formed, and the interval between the comb teeth formed on the end surface of the annular wall 1a is From the opening, it is guided to the flow path 1e that leads to the skirt portion 1b, and is discharged from below the cap. The forced flow of the washing water is used to wash away the spilled and adhering contents in the filling / capping process. The switching mechanism is operated at the timing following the cleaning, and the supply source is switched from the cleaning liquid to the air. As a result, the washing water / compressed air supply means 16 is transformed from the washing water supply means to the compressed air supply means, and this time compressed air is supplied to the sealed space 6b. Then, air is sprayed to the top surface portion of the inner plug 2 through the flow holes of the perforated plate 6c in which a large number of flow holes are formed, and the gaps between the comb teeth formed on the end surface of the annular wall 1a are opened from the opening to the skirt. It is guided to the flow path 1e leading to the portion 1b and discharged from below the cap. This forced air flow removes water adhering to the cleaning process and dries the flow path. Although the composite lid of this embodiment uses a metal inner plug 2, the corrosion of the metal can be completely prevented by removing and drying the cleaning water by the forced air flow after the cleaning.

Next, an embodiment in which the functions of the cleaning water supply means and the compressed air supply means of the composite container lid cleaning system of the present invention employed in the embodiment shown in FIG. 4 are combined with the capping means will be described with reference to FIG. . In this embodiment as well, a cap body (outer shell) 1 such as PET and an inner plug in which a sealing material 3 is fitted in the annular groove of a metal disk having a peripheral edge portion formed in an annular groove and an edge portion curled. 2 and is designed to be applied to a container using a composite lid having a similar structure communicating from the top panel (inner plug 2) to the lid skirt portion 1b via the flow path 1e.
If the container 5 that has been filled has been transported to the second turret T2 for capping, the second turret T2 not only performs capping but also performs cleaning, removal of residual adhering washing water, and drying of the flow path. In order to do everything in the area, the cleaning water supply means (compressed air supply means) is built in the capping mechanism, but this embodiment is not significantly different from the previous embodiment and is structurally cleaned. The water / compressed air supply means 16 is added with a drive mechanism for screwing with a cap gripping portion 6d essential as a capping means. Specifically, as shown in FIG. 6, a rotation drive mechanism (not shown) is formed on the end surface portion of the previous washing water / compressed air supply means 16 so that the cap gripping portion 6 d fits the cap. It is provided.

  When the contents are filled and the container 5 has been transported to the second turret, the capping mechanism 26 that also serves as washing water / pressurized air supply means is driven to be displaced toward the container, as shown in FIG. The capping mechanism 26 is engaged with the knurling on the outer surface of the cap skirt portion 1b by the cap gripping portion 6d, and is brought into close contact with the annular seal member 7 as an O-ring against the annular wall 1a of the outer shell 1 from above. In this state, first, the capping mechanism 26 is rotationally driven, and the cap is capped at the container opening. At this timing, the cleaning water is first pressurized and supplied to the supply path 6a and functions as a cleaning water supply means. The supplied washing water is sprayed to the top surface portion of the inner plug 2 through the flow holes of the perforated plate 6c in which a large number of flow holes are formed as in the previous embodiment, and formed on the end surface of the annular wall 1a. The gap between the comb teeth is guided from the opening to the flow path 1e leading to the skirt portion 1b, and is discharged from below the cap. The forced flow of the washing water is used to wash away the spilled and adhering contents in the filling / capping process. The switching mechanism is operated at the timing following the cleaning, and the supply source is switched from the cleaning liquid to the air. As a result, the capping means 26 is transformed into compressed air supply means, and this time compressed air is supplied to the sealed space 6b. Then, air is sprayed to the top surface portion of the inner plug 2 through the flow holes of the perforated plate 6c in which a large number of flow holes are formed, and the gaps between the comb teeth formed on the end surface of the annular wall 1a are opened from the opening to the skirt. It is guided to the flow path 1e leading to the portion 1b and discharged from below the cap. This forced air flow removes water adhering to the cleaning process and dries the flow path.
