MODE FOR CARRYING OUT THE INVENTION

Hereinafter, a heterogeneous-substance accommodating device according to the present invention is selectively described with reference to FIGS. 1 to 8.

A heterogeneous-substance accommodating device 1 coupled to a mouth of a container includes an accommodating part 104 having a storage space 107 within a main body 100. A soft foldable part F is disposed on an upper portion of the accommodating part 104, and an opening part 108 lengthily extending downward is defined in the bottom of an upper portion of the foldable part F.

Also, a main body mouth 109 is disposed on an upper portion of the main body 100, and a main body mouth sealing part 110 having a main body mouth sealing hole 111 is disposed on an inner lower portion of the main body mouth 109.

Also, a sealing stopper 200 including a sealing hole sealing part 201 for sealing the main body mouth sealing hole 111 is coupled to the main body mouth 109. An anti-forgery cover 300 is assembled to the main body 100 including the sealing stopper 200.

In the accommodating device 1 as described above, a different kind of substance is injected into a storage space 107 of the accommodating part 104, and a lower portion of the accommodating part 104 is sealed by using a sealing part S such as an aluminum sealing member.

Also, the foldable part F is configured so that the opening part 108 breaks and punches the sealing part S when the foldable part F is pressed. In this process, the different kind of substance contained in the storage space 107 drops into the container and then is mixed.

Also, the foldable part F is configured so that the foldable part F is expanded outward and then folded when a force is applied from an upper side of the foldable part F. When the foldable part F is expanded, the foldable part F may have a shape in which a foldable part upper portion folding reference surface FA that is an upper outer portion is wide, and a foldable part lower portion folding reference surface FB that is a lower outer portion is narrow.

Also, when the foldable part F is expanded, the foldable part F forms an expanding reference surface FC having a large outer diameter between the foldable part upper portion folding reference surface FA that is the upper outer portion and the foldable part lower portion folding reference surface FB that is the lower outer portion.

Also, when the foldable part F is expanded, the foldable part F may be spread so that the an upward portion that is an upper side is expanded from the foldable part lower portion folding reference surface FB that is the lower outer portion of the foldable part F.

Explaining the accommodating device 1 in more detail, FIG. 1 illustrates an exemplary example of the accommodating device 1. FIG. 1 illustrates a state in which the cover 300 including an anti-forgery rim 301 is coupled to the main body 100. Here, a protrusion 302 is formed on an inner wall of a lower end of a side surface of the anti-forgery rim 301.

Also, the protrusion 302 is slightly spaced apart from the foldable part F. This is done for a reason in which, if the protrusion 302 contacts an outer circumferential portion of the foldable part F from the beginning, resistance occurs when being sealed again because an outer configuration of the foldable part F is expanded while the foldable part F is folded.

FIG. 2 is a view of a state before the cover 300 is coupled to the main body 100.

FIG. 3 illustrates a state in which the foldable part is folded while being expanded outward when the sealing stopper 200 is pressed.

FIG. 4 illustrates an example in which the main body 100 is primarily injection-molded, i.e., illustrates a state before the foldable part F of FIG. 5 is formed.

For reference, FIG. 4 illustrates a state in which a resin moves in a direction of the accommodating part 104 through the protrusion part 112 at an upper side of the opening part 10. This state is an example of a method for manufacturing a mold.

Also, even though a protrusion part end 113 is separated in a moment while being injection-molded, the protrusion part end 113 immediately returns to its original position.

Also, as illustrated in FIG. 4, a foldable part adhesion surface 114 is formed on an outer circumferential portion of a lower end of the main body mouth 109. In this state, FIG. 5 illustrates a state in which the foldable part F is molded by a multi injection molding machine.

As illustrated in FIG. 5, it is seen that the upper portion of the foldable part F closely adheres to the foldable part adhesion surface 114.

Also, although an auxiliary protrusion pat 115 is disposed on the opening part 108, and a container neck first sealing part 105 and a container neck second sealing part 106 are formed on an outer circumferential portion of the accommodating part 104, the present invention is not limited thereto. For example, other modified structures may be allowable.

Also, a first screw thread 102 and a second screw thread 103 which have standards different from each other are disposed on an inner portion of a side surface 101 that is an outer circumferential portion of the main body 100. Each of the first screw thread 102 and the second screw thread 103 may be used to be selectively coupled to each of different container neck screw threads formed on a container neck.

Also, a dotted line shown in FIG. 5 represents a state in which container necks 100 having shapes different from each other contact the container neck first sealing part 105.

In case of FIG. 6, the expanding reference surface FC in which a central portion of the foldable part F is expanded is illustrated. In this state, the expanding reference surface FC is formed while the foldable part F is swelled in a folded shape due to resistance when the main body 100 is separated (dispensed) from the mold.

In case of FIG. 7, when the sealing stopper 200 is pressed, the foldable part F is folded while being spread outward. In this process, the foldable part adhesion surface 114 receives resistance in a direction of an inner wall of an upper end of the accommodating part 104, and thus, the foldable part F is not folded any more to stop. In the situation of FIG. 7, when the applied force is released, the foldable part F immediately returns to an upper side (see FIG. 8).

Also, in the situation of FIG. 7, when the sealing stopper 200 is lifted, the sealing hole sealing part 201 gets out of the main body mouth sealing part 110 to form a main body mouth sealing hole 111.

In case of FIG. 9, the folding prevention protrusion FD is formed on the bottom of an upper end of the foldable part F so that the foldable part is not folded any more to a predetermined degree or more. Here, the folding prevention protrusion FD may be selected so that the folding prevention protrusion FD does not cover a top or bottom surface of the foldable part F.

In the present invention, the accommodation device 1 of the present invention may be defined as follows.

A heterogeneous-substance accommodating device 1 coupled to a mouth of a container includes an accommodating part 104 having a storage space 107 within a main body 100. A soft foldable part F is disposed on an upper portion of the accommodating part 104, and an opening part 108 lengthily extending downward is defined in the bottom of an upper portion of the foldable part F.

Also, a different kind of substance is injected into the storage space 107 of the accommodating part 104, and a lower portion of the accommodating part 104 is sealed by a sealing part S. When the foldable part F is pressed, the opening part 108 breaks the sealing part S, and thus, the different kind of substance contained in the storage space 107 drops into a container and then is mixed.

Also, the foldable part F has a structure in which a foldable part upper portion folding reference surface FA that is an upper outer portion is wide, and a foldable part lower portion folding reference surface FB that is a lower outer portion is narrow.

Also, the foldable part F is folded in a shape in which an upper side of the foldable part F is spread outward with respect to a lower outer portion thereof while the foldable part F is folded.

Also, when the foldable part F is formed, a main body mouth 109 is disposed on an upper portion of the main body. Also, a foldable part adhesion surface 114 having a shape that is expanded outward is disposed on an outer circumferential portion of a lower end of the main body mouth 109. The soft foldable part F is injection-molded to the foldable part adhesion surface 114.

Particularly, the foldable part F of the accommodating device 1 is configured so that the foldable part F is expanded outward and then folded when a force is applied from an upper side of the foldable part F. Also, a folding prevention part may be disposed on an upper or lower portion of an upper end of the foldable part F so that the foldable part F is not folded to a predetermined degree or more.

Also, the folding prevention part formed on the foldable part F may have a structure in which a folding prevention protrusion FD protrudes downward or upward with respect to the upper portion of the foldable part F. This case may refer to FIG. 9.

Also, an exemplary example of the folding prevention part formed on the foldable part F may include an example in which a foldable part adhesion surface 114 having an expanded shape is formed on a portion at which an upper end of the foldable part F meets a main body mouth 109 of the main body 100.

For another example, as illustrated in FIG. 10, the main body mouth 109 to which a sealing stopper 200 is assembled is disposed on an upper portion of the accommodating deice 1. Also, a soft part 116 on which a main body mouth sealing part 110′ formed of a soft resin is disposed is disposed inside the main body mouth 109. A lower portion of the main body mouth sealing part 110′ is connected to a soft part upper end 117 of the main body mouth 109 by a guide 118, and the main body mouth sealing part 110′ is connected to the foldable part F, which is disposed at a lower side thereof, outside the soft part upper end 117.

In FIGS. 11 and 12, the main body mouth 109 for accommodating the sealing stopper 200 is formed on the main body 100. The main body mouth sealing part 110 is disposed on an inner lower end of the main body mouth 109, and an elastic sealing part 119 is disposed inward from the main body mouth sealing part. In use, as illustrated in FIG. 11, the elastic sealing part 119 is closely attached to the sealing hole sealing part 201 and thus is sealed.

Referring to FIG. 13, a first screw thread 102 is disposed on a lower portion of an inner wall of a side surface 101 of the main body 100 of the accommodating device, and a second screw thread 103 having a standard different from that of the first screw thread 102 is disposed on an upper portion of the inner wall. The side surface 101 on which the first screw thread 102 is formed may be a side surface 101 having a shape that is spread outward. An auxiliary screw thread 121 having an inner diameter greater than that of the first screw thread 102 is formed on the inner wall of the side surface 101 having the spread shape, i.e., an isosceles trapezoid shape.

Also, the auxiliary screw thread 121 includes a three-line auxiliary screw thread 121 so that the auxiliary screw thread 121 is coupled to a container neck having a container neck screw thread with a 30 MM standard. The auxiliary screw thread 121 may have three lines that are angled at about 120 degrees, and each of the three lines of the auxiliary screw thread 121 may have a length of about 10 MM to about 30 MM, but is not limited thereto.

In case of FIG. 14, an example in which the main body 100 is coupled to a container neck 1000A having a large size is illustrated. Particularly, a state in which the auxiliary screw thread 121 is hung on and fixed to the container neck screw thread 1001.

In case of FIG. 15, a modified example of an opening part 108A formed inside an accommodating part 104A is illustrated. Here, an opening end 122 is split by a space 123. In use, the opening end 122 punches two positions of a sealing part SA. This is shown as a dotted line in FIG. 15.

In case of FIG. 16, a tapered punching pin 124 is disposed on a side of the opening part 108A. In use, the opening end 122 punches the sealing part SA that seals a lower portion of the accommodating part 104A to form a dropping space SC, and the punching pin 124 forms a punching part SB.

In case of FIG. 17, an example in which a sealing hole sealing part 201A formed on the sealing stopper 200 is formed of a soft resin is illustrated. Preferably, the sealing hole sealing part 201A may lengthily extend downward from a sealing stopper upper end soft part 203 that is disposed at an upper end.

In case of FIG. 18, the accommodating device 1 that is described above and a packaging system 400 of the accommodating device 1 are illustrated. In detail, the accommodating device 1 is sorted by a feeder constituting a portion of the packaging system 400. The sorted accommodating device 1 is transferred to a supply part 410, and the accommodating device 1 supplied to the supply part 410 is transferred to an arranged block 421 constituting a main transfer conveyer 420. Then, defects of the accommodating device 1 transferred to the block 421 are inspected by a series of inspection device 430.

Also, the accommodating device 1 in which the inspection is completed is transferred for the next process. Simultaneously, information with respect to whether the inspection is performed is transmitted into a computation apparatus, and then, an accommodating device 1 that is determined as a defective product in a series of processes is discharged to a defective product corner.

Also, the accommodating device 1 transferred as described above is filled with contents into an accommodating part storage space thereof, which is aligned with the block at a powder filling part 400 or liquid filling part 450 according to input information inputted into the computation apparatus (see the accommodating part 104 and the storage space 107 which are illustrated in FIG. 18). Then, the accommodating device 1 in which the filling is completed moves for the next process together with the block 421.

Also, a film (a roll film FR) that is cut by a film feeder and cutting system 460 contacts an upper end of the accommodating part, which corresponds to an upper end of the moving accommodating device 1. The accommodating device 1 together with the film is sealed by a sealer 480 in the next process.

Here, the sealers 480 and 480A successively seal the accommodating device 1 accommodated in the block 421 by dividing an even number and odd number.

As described above, the accommodating device 1 in which the sealing is completed is inspected by the inspection part 490, and then is transferred to a transfer block MB of an auxiliary transfer conveyer for performing the next process. The transferred accommodating device 1 is packaged by a film packaging part FS.

For reference, the film packaging part FS includes at least one guide in an accommodating device input guide. The accommodating device is inputted into a film that extends from a roll-shaped film FL constituting a portion of the film packaging part FS along the guide, and a packaging container together with the inputted accommodating device 1 is formed in the sealing part. The formed packaging container is separated as one independent packaging container and then is discharged.

Alternatively, the accommodating device 1 in which the inspection is completed is directly inputted into the guide (the supply part) constituting the film packaging part FS and then is packaged.

FIGS. 19 and 20 relates to a sorting device 500 for performing a process in which the accommodating device 1 is supplied into the supply part 410 of the packaging system 400. In detail, a number of accommodating devices 1 is supplied into the sorting device 500, and the supplied accommodating devices 1 move into a space in the sorting belt 510.

Also, the sorting belt 510 continuously rotates, and the accommodating devices 1 hung on the sorting belt 510 are supplied into the supply part 410 of FIG. 18.

Also, the sorting belt 510 may be freely designed in width and space.

In case of FIG. 20, an example in which the sorting belt 510 is hung on the side surface 101 of the accommodating device 1 is illustrated. Preferably, the sorting belt 510 and a space in the sorting belt 510 may be formed so that an inclination part 101A is hung on the sorting belt 510.
