Abstract
An object of the present invention is to provide a sealing device and a sealing method with which oxygen substitution can be sufficiently carried out even in a bag-like container. The present invention is a sealing device for putting a content into a bag-like container and sealing the container, and includes a content supply portion that supplies the content to the container having an opening in an open state, an inert gas supply portion that supplies inert gas to the container, a liquefied inert gas supply portion that supplies liquefied inert gas to the container, and a sealing portion that seals the opening of the container after the liquefied inert gas is supplied.
Description
- The present invention relates to a sealing device and a sealing method.
- If a container is filled with a content such as a food product and is then sealed, there is a possibility that oxygen existing in the container oxidizes the content. For this reason, conventionally, before the container filled with the content is sealed, inert gas is injected to substitute the inert gas for the oxygen. However, if inert gas is used, a problem arises in that the gas exchange takes time. For example,
Patent Literature 1 discloses a technique of using liquefied inert gas, in place of inert gas. That is to say, liquefied inert gas is injected into the container and is evaporated within the container, thereby carrying out oxygen substitution. - Patent Literature 1: JPS62-158626 A
- As described above, in
Patent Literature 1, oxygen substitution is carried out by injecting liquefied inert gas. However, with a bag-like container, if the liquefied inert gas is evaporated and permeates the container, a problem arises in that it becomes difficult to close an opening of the container, or in that it is difficult to control the amount of gas in the container, that is, the volume of the container. For this reason, the opening of the container needs to be closed as soon as possible after injecting the liquefied inert gas. However, if the opening of the container is thus closed at a short time after injection of the liquefied inert gas, another problem arises in that oxygen substitution cannot be sufficiently carried out. - The present invention has been made in order to solve the foregoing problems, and it is an object of the present invention to provide a sealing device and a sealing method with which oxygen substitution can be sufficiently carried out even in a bag-like container.
- The present invention is a sealing device for putting a content into a bag-like container and sealing the container, including: a content supply portion configured to supply the content to the container having an opening in an open state; an inert gas supply portion configured to supply inert gas to the container; a liquefied inert gas supply portion configured to supply liquefied inert gas to the container; and a sealing portion configured to seal the opening of the container after the liquefied inert gas is supplied.
- With this configuration, the following effect can be achieved. With a bag-like container, if the liquefied inert gas is evaporated within the container, it becomes difficult to close the opening of the container, or it becomes difficult to adjust the amount of gas in the container. On the other hand, if the opening of the container is closed at a short time after injection of the liquefied inert gas, there is a possibility that oxygen substitution cannot be sufficiently carried out.
- For this reason, by supplying the inert gas before supplying the liquefied inert gas as described above, oxygen substitution within the container can be sufficiently carried out. Consequently, the amount of oxygen remaining in the container can be reduced.
- In the above-described device, it is possible that the inert gas supply portion supplies the inert gas to the container while the content is being supplied. With this configuration, the time taken until the opening of the container is sealed can be shortened.
- In the above-described device, it is possible that the content supply portion includes at least one guide member that is inserted into the container from the opening thereof and guides the supply of the content. As a result of providing this guide member, supply of the content is facilitated even in the case of a soft container having a low rigidity, such as a bag-like container.
- In the above-described device, it is possible that two of the guide members are provided, at least end portions of the two guide members on a side of being inserted into the opening of the container are configured to approach and separate from each other, and the content is supplied into the container from a gap between the two guide members.
- With this configuration, the end portions of both guide members on the container opening side are brought close to each other and the overall thickness of these guide members thereby becomes small, and accordingly the guide members can be easily inserted into the opening of the container. Then, if a gap is formed by separating the guide members from each other after the guide members are inserted, this gap can be used as a passage for the content, and accordingly the content can be easily supplied.
- In the above-described device, it is possible that the inert gas supply portion includes a gas supply pipe that is attached to the guide member. With this configuration, the gas supply pipe can be inserted together with the guide member into the container, and accordingly, even if the gas supply pipe has a low rigidity and is soft, for example, the gas supply pipe can be reliably inserted into the container. Furthermore, since the gas supply pipe can be inserted up to a deep position within the container, oxygen substitution at the deep position within the container can be reliably carried out, and the residual ratio of oxygen can be further reduced.
- A sealing method according to the present invention is a method for supplying a content into a bag-like container and sealing the container, the method including: a step of supplying the content to the container having an opening in an open state; a step of supplying inert gas to the container; a step of supplying liquefied inert gas to the container after the inert gas is supplied; and a step of sealing the opening of the container after the liquefied inert gas is supplied.
- It is possible that the step of supplying the inert gas is performed during the step of supplying the content.
- It is possible that the step of supplying the inert gas includes: a sub-step of inserting a gas supply pipe for supplying the inert gas into the container; and a sub-step of discharging the inert gas from the gas supply pipe.
- According to the present invention, oxygen substitution can be sufficiently carried out even in a bag-like container.

FIG. 1 shows a front view, a side view, and a plan view of a container used with this device.FIG. 2 is a plan view showing a schematic configuration of this sealing device. - As shown in
FIG. 1 , this sealing device is an device for putting a content such as a food product into a bag-like container and sealing the container. With this device, processes of opening an upper opening of the container, injecting the content and inert gas through this opening, further injecting liquefied inert gas through the opening, and thereafter closing the opening are performed. The container used with this device is configured as shown inFIG. 1 , for example. As shown inFIG. 1 , acontainer 100 is a so-called stand-up pouch that is made of sheet material such as plastic, and has a pair ofside face portions 101 constituting side faces of thecontainer 100, and abottom face portion 102 constituting a bottom face thereof. Theside face portions 101 are formed by overlaying a pair of pieces of side-face sheet material, and both side ends of the pieces of side-face sheet material are heat-sealed together so as to form an opening in the upper part thereof. A piece of bottom-face sheet material is heat-sealed to the pieces of side-face sheet material so as to close a lower opening formed by both pieces of side-face sheet material, thereby constituting thebottom face portion 102. As described later, thecontainer 100 is conveyed to the aforementioned sealing device with the upper opening of thecontainer 100 open, and the upper opening is closed by this device. - 1. Schematic Configuration of Sealing Device
- Next, a schematic configuration of the sealing device will be described. As shown in
FIG. 2 , this sealing device includes arotatable support 1 having a ring shape when seen in a plan view. A plurality ofcontainer holders 2 are attached at predetermined intervals to thesupport 1, and thesecontainer holders 2 rotate with thesupport 1. Fillingauxiliary devices 3 supported by thesupport 1 are provide above therespective container holders 2. Each fillingauxiliary device 3 assists in filling thecontainer 100 with the content. - A container supply unit 4, a
content conveyance unit 5, and a conveyance unit for sealing 6 are adjacent to thesupport 1. The container supply unit 4 is configured to supply thecontainer 100 to eachcontainer holder 2 on thesupport 1 at a receiving position in a peripheral portion of thesupport 1. That is to say, since thesupport 1 rotates, the container supply unit 4 supplies thecontainer 100 to each of thecontainer holders 2 that sequentially pass through the receiving position. Thecontainer 100 held by eachcontainer holder 2 is filled with the content and inert gas as described later, thereafter separates from thecontainer holder 2 at a separation position, and is delivered to the conveyance unit for sealing 6. The separation position is provided on the side opposite to the receiving position across thesupport 1. That is to say, thecontainer 100 delivered to eachcontainer holder 2 at the receiving position rotates with thesupport 1 by about 180 degrees, and is thereafter delivered from thecontainer holder 2 to the conveyance unit for sealing 6 at the separation position. - The
content conveyance unit 5 is for conveying a plurality ofcontent supply devices 51, and has aconveyance path 52 that approaches thesupport 1 from a position separated from thesupport 1, extends along the circumference of thesupport 1, and thereafter separates from thesupport 1. Thecontent supply devices 51 are conveyed along theconveyance path 52 at predetermined intervals. Eachcontent supply device 51 faces a corresponding fillingauxiliary device 3 on thesupport 1, and is conveyed along thesupport 1 so as to maintain this facing state. That is to say, thecontent conveyance unit 5 conveys thecontent supply devices 51 in synchronization with the fillingauxiliary devices 3. - The conveyance unit for sealing 6 has a
conveyance path 61 extending from the aforementioned separation position, and a plurality ofcontainer support devices 62 move at predetermined intervals on thisconveyance path 61. Eachcontainer support device 62 conveys thecontainer 100 delivered from thesupport 1 at the separation position while holding thecontainer 100. Furthermore, a liquefied inertgas supply portion 63 that injects liquefied inert gas into thecontainer 100, and a sealingportion 64 that seals the upper opening of the container are provided on theconveyance path 61 of the conveyance unit for sealing 6. - 2. Support
- Next, the
support 1 will be described in detail with reference toFIGS. 3 and 4 .FIG. 3 shows a cross-sectional view of the container holder and the filling auxiliary device, andFIG. 4 shows a plan view (a) and a cross-sectional view (b) of the filling auxiliary device. As mentioned above, thecontainer holders 2 are arranged at predetermined intervals at the peripheral edge of thesupport 1, and the fillingauxiliary devices 3 are arranged above therespective container holders 2. Note that although eightcontainer holders 2 and fillingauxiliary devices 3 are shown inFIG. 2 , the number thereof is not particularly limited. As shown inFIG. 3 , eachcontainer holder 2 can move up and down with respect to the corresponding fillingauxiliary device 3, and has a pair offixation members 21 that are fixed to the respective side faceportions 101 of thecontainer 100. As described later, thefixation members 21 are fixed to the respective side faceportions 101 of thecontainer 100 that is conveyed in a state where its upper opening is open, and maintains the state where the upper opening of thecontainer 100 is open. Eachcontainer 100 rotates, in the state where its upper opening is open, with thesupport 1. - As shown in
FIG. 4 , each fillingauxiliary device 3 includes twoguide members 31 that are arranged so as to face each other. Bothguide members 31 are made of plate material extending in a vertical direction, and are supported so as to be able to pivot around their upper end portions. As a result of theguide members 31 facing each other, their upper portions form a rectangular opening, and their lower portions forms a beak-like shape. Theguide members 31 are configured such that a space therebetween expands and narrows as a result of theguide members 31 pivoting around their upper end portions and their lower portions approaching and separating from each other. - A
gas supply pipe 7 that supplies inert gas is attached to each fillingauxiliary device 3. Inert gas such as nitrogen is supplied to thisgas supply pipe 7 from a gas supply source (not shown). Eachgas supply pipe 7 is attached to the outer face of one of theguide members 31, and extends from the upper part toward the lower part of theguide member 31. Thegas supply pipe 7 is open near the lower part of theguide member 31, and ejects the inert gas. - 3. Container Supply Unit
- Next, the container supply unit 4 will be described. The container supply unit 4 has a
conveyance path 41 extending up to the aforementioned receiving position, and is provided with a pair ofsuction members 42 that open the upper opening of thecontainer 100, near the receiving position. Thesuction members 42 are configured to approach and separate from each other, and expand the upper opening of thecontainer 100 by suctioning the respective side face portions of the conveyedcontainer 100 and thereafter separating from each other. Theattachment members 42 are configured to then deliver thecontainer 100 to thecontainer holder 2 of thesupport 1, in the state where the upper opening of thecontainer 100 is expanded. - 4. Content Conveyance Unit
- Next, the
content conveyance unit 5 will be described in detail with reference also toFIG. 5 .FIG. 5 shows perspective views of a containing device. As shown inFIG. 2 , thecontent conveyance unit 5 is provided withcontent supply devices 51 that move along theconveyance path 52, and as shown inFIG. 5 , eachcontent supply device 51 is provided with a cup-like containingdevice 52 in which the content is put. Each containingdevice 52 is filled with the content at a content supply portion (not shown), and this content is supplied to eachcontainer 100. That is to say, the volume of each containingdevice 52 corresponds to the amount of the content to be put in thecontainer 100. Each containingdevice 52 is pivotably supported by the correspondingcontent supply device 51, and as shown inFIG. 5( b), the containingdevice 52 inclines as a result of pivoting, and thus causes the content that is put therein to fall. As mentioned above, eachcontent supply device 51 is arranged so as to face the corresponding fillingauxiliary device 3, and the containingdevice 52 is arranged at a position at which the content falls toward the upper opening of the aforementioned twoguide members 31 when the containingdevice 52 inclines. Note that the containingdevice 51 does not cause the content to fall at a time, but causes the content to fall while gradually inclining, and accordingly, the impact received by the content due to the falling can be reduced. - 5. Conveyance Unit for Sealing
- Subsequently, the conveyance unit for sealing 6 will be described in detail. As shown in
FIG. 2 , the conveyance unit for sealing 6 is provided with a plurality ofcontainer support devices 62 that support thecontainer 100. Eachcontainer support device 62 has a pair of fixation members 60 (seeFIG. 8 ), and can hold, with thesefixation members 60, thecontainer 100 received from eachcontainer holder 2 on thesupport 1, in the state where the upper part of thecontainer 100 is open. The liquefied inertgas supply portion 63 provided in the conveyance unit for sealing 6 is provided with anozzle 631 for discharging the liquefied inert gas (seeFIG. 8 ), and thisnozzle 631 is arranged above theconveyance path 61. With this configuration, the liquefied inert gas is injected from thenozzle 631 to thecontainer 100 that passes through theconveyance path 61 in the state where the upper opening of thecontainer 100 is open. More specifically, an on-off valve is contained in thenozzle 63, and the liquefied inert gas intermittently drips down from thenozzle 63 and is supplied into thecontainer 100, as a result of this on-off valve being opened and closed every predetermined time period. In theconveyance path 61, the sealingportion 64 is provided on the downstream side of the liquefied inertgas supply portion 63, and the upper opening of thecontainer 100 in an open state is closed by pressing the upper opening from both sides, and thecontainer 100 is sealed by means of heat-sealing. - 6. Process of Sealing by Sealing Device
- Subsequently, a sealing process in the sealing device configured as described above will be described with reference also to
FIGS. 6 to 8 .FIGS. 6 to 8 are cross-sectional views for illustrating the sealing process. The following is a description of sealing in the case of putting a number of ball-shaped food products. Initially, by rotating thesupport 1, thecontainer holders 2 and the fillingauxiliary devices 3 rotate therewith. Eachcontainer 100 is supplied one-by-one from the container supply unit 4 to therotating support 1. In the container supply unit 4, the upper opening of eachcontainer 100 is opened immediately before the receiving position, and thecontainer 100 in this open state is delivered from the container supply unit 4 to eachcontainer holder 2. Thecontainer holder 100 holds the state where the opening of thecontainer 100 is open, using thefixation members 21. In this state, as shown inFIG. 6( a), thecontainer holder 2 is raised, and theguide members 31 of the corresponding fillingauxiliary device 3 are thereby inserted into the opening of thecontainer 100. At this time, the lower end portions of bothguide members 31 approach each other, making the overall thickness small, and accordingly theguide members 31 are easily inserted into the opening of thecontainer 100. Upon the lower end portions of bothguide members 31 being inserted into thecontainer 100, the lower end portions of theseguide members 31 pivot so as to separate from each other, as shown inFIG. 6( b). Thus, the opening of thecontainer 100 can be widely expanded, and a gap through which the content passes is formed between theguide members 31. At this time, the distance between the lower end portions of theguide members 31 may be gradually expanded as the lower end portions of theguide members 31 proceed through the inside of thecontainer 100 after being inserted into the opening of thecontainer 100. - The corresponding containing
device 52 filled with the content is also conveyed in parallel therewith, by thecontent conveyance unit 5. The containingdevice 52 is conveyed along the circumference of thesupport 1 so as to face the corresponding fillingauxiliary device 3. While thecontainer 100 moves from the receiving position to the separation position, the containingdevice 52 inclines, and causes the content to fall as shown inFIG. 6( b). The content falls toward the upper opening of theguide members 31 of the fillingauxiliary device 3, passes through the gap between theguide members 31, and is put into thecontainer 100. At this time, the inert gas is discharged from thegas supply pipe 7 that is inserted together with theguide members 31 into thecontainer 100. Since theguide members 31 are inserted up to the intermediate part to the vicinity of the bottom part of thecontainer 100, the inert gas is discharged from the intermediate part up to the vicinity of the bottom part of thecontainer 100. As a result, oxygen substitution is carried out in the intermediate part to the vicinity of the bottom part of thecontainer 100. Note that theguide members 31 can also be caused to proceed to the inside of thecontainer 100 more deeply than in the example inFIG. 6 . That is to say, if the lower end portions of theguide members 31 are caused to reach the vicinity of the bottom face portion of thecontainer 100, the content can be reliably put up to the vicinity of thebottom face portion 102 of thecontainer 100. At this time, since thegas supply pipe 7 also reaches the vicinity of thebottom face portion 102 of thecontainer 100, oxygen substitution can be carried out with the inert gas, from thebottom face portion 102 up to the vicinity of the opening of thecontainer 100. Consequently, the substitution rate can be improved. - Upon the content being thus put in the
container 100, as shown inFIG. 7 , thecontainer holder 2 is lowered, and theguide members 31 are withdrawn from thecontainer 100. Thecontainer holder 2, upon arriving at the separation position, delivers thecontainer 100 to the correspondingcontainer support device 62 of the conveyance unit for sealing 6, in the state where the upper opening of thecontainer 100 is open. Thecontainer support device 62 fixes thefixation members 60 to thecontainer 100, and conveys thecontainer 100 along theconveyance path 61 while maintaining the state where the upper opening of thecontainer 100 is open. Then, as shown inFIG. 8 , when thecontainer 100 passes below thenozzle 631 of the liquefied inertgas supply portion 63, the liquefied inert gas drips down from thenozzle 631 and falls into thecontainer 100 from the upper opening thereof. The liquefied inert gas begins to be evaporated within thecontainer 100, and oxygen substitution is thereby carried out within thecontainer 100. Subsequently, upon thecontainer 100 passing through the sealingportion 64, the upper opening is sealed. Thereafter, the liquefied inert gas is completely evaporated within the container, thus bulging thecontainer 100 to a predetermined size. By thus bulging thecontainer 100, the content can be prevented from being broken when an external force is exerted on thecontainer 100. Accordingly, the present invention is particularly advantageous for containing soft and fragile food products or the like. - In a specific example of the above process, for example, assuming that the amount of injected inert gas is about 200 to 250 mL, the amount of injected liquefied inert gas is about 1 to 2 g, and the time taken from injection of the liquefied inert gas until sealing of the container opening is about 0.3 to 3 seconds when the volume of the container is 1000 mL and the amount of the content is about 200 to 250 mL in terms of volume, the residual ratio of oxygen can be 8% or smaller. Furthermore, the container can be bulged to the extent that, even if the container is pressed from the outside, the force is not exerted on the content. However, the above is only an example, and the present invention is not limited thereto.
- 7. Features
- As described above, according to the present embodiment, the inert gas is supplied, in addition to the liquefied inert gas, into the
container 100, and accordingly oxygen substitution within thecontainer 100 can be sufficiently carried out. Consequently, the amount of oxygen remaining in thecontainer 100 can be reduced. In particular, as a result of injecting the inert gas, control of the amount of oxygen substitution does not need to be adjusted only at the time of the injection of the liquefied inert gas, and accordingly, the time taken from the injection of the liquefied inert gas until sealing and the dripping amount of the liquefied inert gas can be adjusted with a weight on the adjustment of the container volume. Accordingly, the amount of oxygen substitution and the container volume can be controlled with accuracy. - 8. Modifications
- Although an embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and may be modified in various manners within the gist of the present invention. For example, although the filling of the container with the content and the inert gas is performed while rotating the container holders with the support in the above embodiment, the conveyance path used in the sealing process is not limited thereto, and for example, a linear conveyance path may be used.
- The container supply unit 4, the
content conveyance unit 5, and the conveyance unit for sealing 6 do not need to be provided individually, and there is no particular limitation as long as the sealing device is an device with which, during a series of processes, the upper opening of the container is brought into an open state, the content and the inert gas are injected, the liquefied inert gas is thereafter injected, and the opening is sealed. - Although the container is a stand-up pouch in the above embodiment, the present invention is also applicable to a container having an opening in a horizontal direction. The content to be put in the container may be a food product in grain, chip, or bean form, or a solid food product, or may also be a fragile content.
- In the above embodiment, regarding the
gas supply pipe 7 attached to theguide members 31, the position of an outlet port of thegas supply pipe 7 does not have to be in the lower part of theguide members 31, and may be changed as appropriate depending on the amount of the content, the form of the container, or the like. Furthermore, it is also possible that the gas supply pipe is not attached to the guide members but is inserted individually into the container. Note that the form of the guide members is not particularly limited either, and is not particularly limited as long as the guide members can guide the supply of the content. For example, although bothguide members 31 are pivotably supported and the lower end portions thereof approach and separate from each other in the above embodiment, theguide members 31 can be configured such that the entire faces thereof approach and separate from each other. - The form of the container is not limited to the above-described one either, and the device according to the present invention is applicable to any bag-like container having an opening in the upper part thereof.
