Definitions
- the present invention relates to a container which contains fluid such as liquid or a gel-like body, a portion package in which fluid is sealed in the container, a manufacturing method of the portion package, and an opening method of the portion package.
- Portion packages are known in which fluid such as liquid or a gel-like body (contents) is sealed in a container (refer to JP-UM-A-56-141173 and JP-T-2003-512107 (The symbol “JP-T” as used herein means a published Japanese translation of a PCT patent application.), for example).
- a portion package container disclosed in JP-UM-A-56-141173 is provided with a pipe-shaped container body which is open at one end and has a bottom at the other end.
- the bottom of the container body is formed with a discharge hole for discharging the fluid contained.
- the open end of the container body is sealed with a sealing member that is fitted in the open end, and the bottom discharge hole is sealed with a lid member that covers the bottom end. Fluid is poured into the container through its open end in a state that the discharge hole is sealed with the lid member, and sealed in the container by fitting the sealing member into the open end.
- a portion package container disclosed in JP-T-2003-512107 is provided with a pipe-shaped container body which is open at both ends. Each open end of the container body is sealed by welding a film-Like sealing member to the end surface. Fluid is poured into the container through one open end in a state that the other open end is sealed with the sealing member, and sealed in the container by welding the sealing member to the end surface of the one open end.
- the open end or one of the open ends serves as an opening for fluid pouring. With this structure, it is difficult to pour fluid into the container so as to fill it up.
- the end surface is easily covered with the expanding fluid.
- the above phenomenon may obstruct joining of the sealing member to the end surface of the open end and thereby render the sealing of the open end with the sealing member incomplete.
- the present invention has been made in the above circumstances, and an object of the present invention is therefore to facilitate charging of a portion package container with fluid and to enable reliable sealing of its pouring opening (or holes) with a sealing member.
- a container comprising a container body having a short pipe shape in which one end is open and the other end is provided with a bottom plate which is formed with a pouring hole in a partial region; and a first sealing member which is joined to an end surface of an open end of the container body and thereby seals the open end.
- a portion package comprising the container of item (1); fluid contained in the container; and a second sealing member which is joined to an outside surface of the bottom plate and thereby seals the pouring hole.
- a manufacturing method of a portion package comprising the steps of pouring fluid through a pouring hole into a short-pipe-shaped container in which one, open end is sealed with a first sealing member and a bottom plate which is provided at the other end is formed with the pouring hole; and sealing the pouring hole by joining a second sealing member to an outside surface of the bottom plate of the container into which the fluid has been poured.
- one end of the container body is provided with the bottom plate which is formed with the pouring hole in a partial region. Therefore, the surface of fluid that has been poured into the container is flattened by means of the bottom plate. In this manner, the container can be charged with fluid easily.
- the first sealing member is joined to the end surface of the open end of the container body to seal the open end before pouring of fluid, fluid being poured does not obstruct joining of the first sealing member to the open end of the container body.
- the second sealing member is joined to the outside surface of the bottom plate having the pouring hole to seal the pouring hole after pouring of fluid.
- the outside surface of the bottom plate is wider than an end surface that would be obtained if the bottom-plate-side end of the container body were an open end. Therefore, even if fluid expands to wet a portion around the pouring hole, a joining region can be obtained on the outside surface of the bottom plate outside that portion so as to surround the pouring hole. The pouring hole can thus be sealed reliably with the second sealing member.

- FIGS. 1 and 2 show a container according to an embodiment of the present invention.
- the container 1 is provided with a container body 2 and a first sealing member 3 .
- the container body 2 is shaped like a short pipe, and its one end is open and the other end is provided with a bottom plate 4 .
- the bottom plate 4 is formed with openings 5 .
- the container body 2 is shaped like a short pipe that is generally rectangular in a plan view and the openings 5 occupy four corner portions of the bottom plate 4 and are generally circular in a plan view.
- part of the openings 5 may serve as pouring holes with the other openings 5 used as outlets for venting air out of the container 1 .
- the outside surface 4 a of the bottom plate 4 is formed with plural annular ribs 6 , each of which is formed so as to surround the associated opening 5 and to be distant from the edge of the associated opening 5 and the associated portion of the edge of the outside surface 4 a of the bottom plate 4 .
- the distance between each rib 6 and the associated opening 5 is set so that fluid 12 that overflows the container 1 after its capacity is reached is contained inside each rib 6 taking into consideration a variation of a pouring amount of fluid 12 when it is poured into the container 1 using a dispenser or the like.
- the first sealing member 3 is joined to an end surface 7 a of an open end 7 of the container body 2 , whereby the open end 7 is sealed.
- the first sealing member 3 is formed by, for example, laminating a metal foil of aluminum or the like on the surface of a thermoplastic resin film, and is typically welded to the end surface 7 a of the open end 7 .
- the method for joining the first sealing member 3 to the end surface 7 a of the open end 7 is not limited to welding.
- the first sealing member 3 may be joined to the end surface 7 a of the open end 7 with adhesive that is applied to the end surface 7 a of the open end 7 . Therefore, the first sealing member 3 is not limited to weldable members.
- FIG. 3 shows an example portion package in which fluid 12 is sealed in the container 1 .
- the portion package 10 is configured in such a manner that a second sealing member 11 is joined to the outside surface 4 a of the bottom plate 4 of the container 1 which is filled with the fluid 12 and all of the openings 5 of the bottom plate 4 are sealed.
- the fluid 12 has been poured into the container 1 until its capacity is reached substantially and is sealed in the container 1 .
- the second sealing member 11 is formed by, for example, laminating a metal foil of aluminum or the like on the surface of a thermoplastic resin film, and is typically welded to the outside surface 4 a of the bottom plate 4 of the container 1 .
- the method for joining the second sealing member 11 to the outside surface 4 a of the bottom plate 4 is not limited to welding.
- the second sealing member 11 may be joined to the outside surface 4 a of the bottom plate 4 with adhesive that is applied to the outside surface 4 a of the bottom plate 4 . Therefore, the second sealing member 11 is not limited to weldable members.
- FIGS. 4A-4D illustrate a manufacturing process of the portion package 10 .
- Fluid 12 is poured through the openings 5 of the bottom plate 4 into the container 1 whose open end 7 is sealed with the first sealing member 3 .
- Fluid 12 is poured by approximately a prescribed amount using a dispenser, for example.
- the fluid 12 that has been poured into the container 1 has a concave surface, that is, because of its surface tension, a peripheral portion 12 a of its surface that is in contact with the inside surface of the side wall of the container 1 is higher than a central portion 12 b (see FIG. 4A ).
- the peripheral portion 12 a of the fluid 12 After the peripheral portion 12 a of the fluid 12 has reached the inside surface 4 b of the bottom plate 4 of the container 1 , the peripheral portion 12 a remains there even if further fluid 12 is poured into the container 1 .
- the central portion 12 b of the surface of the fluid 12 since a space exists between the central portion 12 b of the surface of the fluid 12 and the inside surface 4 b of the bottom plate 4 , the central portion 12 b rises gradually and comes into contact with the inside surface 4 b of the bottom plate 4 as further fluid 12 is poured into the container 1 . That is, the surface of the fluid 12 , which has been concave, is flattened by means of the inside surface 4 b of the bottom plate 4 .
- the container 1 is thus filled with the fluid 12 (see FIGS. 4B and 4C ).
- the second sealing member 11 is joined to the outside surface 4 a of the bottom plate 4 . All of the openings 5 of the bottom plate 4 are sealed with the second sealing member 11 , whereby the fluid 12 is sealed in the container 1 (see FIG. 4D ).
- FIG. 5 illustrates, in detail, a joining state of the container 1 and the second sealing member 11 around one opening 5 .
- FIG. 5 shows a state that fluid 12 has expanded to wet the portion around the opening 5 .
- the second sealing member 11 is joined to the outside surface 4 a of the bottom plate 4 in a state that fluid 12 has expanded to wet the portion around each opening 5 . Since the outside surface 4 a of the bottom plate 4 is wider than an end surface that would be obtained if the bottom-4-side end of the container 1 were an open end, even if fluid 12 expands to wet the portion around each opening 5 , a joining region can be formed between the outside surface 4 a of the bottom plate 4 and the second sealing member 11 outside that portion so as to surround each opening 5 .
- the outside surface 4 a of the bottom plate 4 is formed with the plural annular ribs 6 and each rib 6 surrounds the associated opening 5 so as to be distant from the edge of the associated opening 5 .
- each rib 6 is distant from the associated portion of the edge of the outside surface 4 a of the bottom plate 4 . Therefore, expanding fluid 12 is dammed up by each rib 6 and a joining region can be secured outside each rib 6 so as to surround the associated opening 5 .
- each opening 5 is surrounded by a joining region of the second sealing member 11 and the outside surface 4 a of the bottom plate 4 , whereby the openings 5 can be sealed reliably with the second sealing member 11 .
- FIGS. 6A-6C illustrate an example opening tool for the portion package 10 and an example process of opening the portion package 10 using the opening tool.
- the opening tool 20 is equipped with a projection 22 which is provided on the top surface of a substrate 21 at the center and a sharp nail 23 which projects from a portion of the edge of the top surface of the projection 22 .
- the projection 22 can be inserted into the container 1 from the open end 7 side of the container 1 of the portion package 10 and, when inserted, fitted in the container 1 loosely.
- the first sealing member 3 with which the open end 7 of the container 1 of the portion package 10 is sealed is pressed against the projection 22 and perforated by the nail 23 of the top surface of the projection 22 (see FIG. 6A ).
- the first sealing member 3 continues to be pressed against the projection 22 , whereby the first sealing member 3 is broken starting from the hole formed by the nail 23 and the portion package 10 is opened.
- the projection 22 is inserted into the container 1 .
- the fluid 12 that has been sealed in the portion package 10 pressed out by the projection 22 .
- the pressed-out fluid 12 is received by the substrate 21 and collected (see FIG. 6B ).
- the projection 22 When the projection 22 is inserted fully into the container 1 , the inside space of the container 1 is occupied by the projection 22 , whereby the fluid 12 that was sealed in the portion package 10 can be collected substantially in its entirety (see FIG. 6C ).
- FIGS. 7 and 8 show an example container sealing machine for sealing the openings 5 of the container 1 .
- the sealing machine 100 seals the openings 5 of the container 1 by joining the second sealing member 11 to the outside surface 4 a of the bottom plate 4 of the container 1 .
- Plural containers 1 are arranged on each pallet 108 and containers 1 are supplied to the sealing machine 100 on a pallet-by-pallet basis.
- FIG. 7 is simplified in that only one container 1 is shown for each pallet 108 .
- the sealing machine 100 is equipped with a conveyor 101 for conveying pallets 108 on which containers 1 are arranged, a supplying unit 102 for supplying a sealing material 120 which is a material of second sealing members 11 , a feeding unit 103 for feeding the sealing material 120 supplied from the supplying unit 102 , a pouring unit 104 for pouring fluid into containers 1 , a joining unit 105 for joining part of the sealing material 120 to each container 1 mounted on each pallet 108 , a cut-out unit 106 for cutting a joined portion (second sealing member 11 ) that has been joined to each container 1 on each pallet 108 out of the sealing material 120 , and a separating unit 107 for separating the cut-out joined portion (second sealing member 11 ) from the other part of the sealing material 120 .
- the conveyor 101 includes a guide rail 110 which extends along a pallet conveying path, an engaging member 111 for engaging with plural pallets 108 which are to engage with pallets 108 mounted on the guide rail 110 in a disengageable manner, and a drive mechanism 112 for driving the engaging member 111 .
- the engaging member 111 has a base 113 which is disposed under and extends parallel with the guide rail 110 and plural pins 114 which are erected from the base 113 with a prescribed pitch.
- the drive mechanism 112 has elevation drive mechanisms 115 such as cylinder-piston units which support and drive (i.e., elevate and lower) the engaging member 111 and a translation drive mechanism 116 such as a linear motor which reciprocation-drives the elevation drive mechanisms 115 in the pallet conveying path.
- elevation drive mechanisms 115 such as cylinder-piston units which support and drive (i.e., elevate and lower) the engaging member 111 and a translation drive mechanism 116 such as a linear motor which reciprocation-drives the elevation drive mechanisms 115 in the pallet conveying path.
- the engaging member 111 When elevated being driven the elevation drive mechanisms 115 , the engaging member 111 causes the pins 114 to engage with plural pallets 108 mounted on the guide rail 110 . Then, driven by the translation drive mechanism 116 , the elevation drive mechanisms 115 and the engaging member 111 supported by them go forward along the conveying path and the plural pallets 108 which are engaged with the pins 114 go forward on the guide rails 110 together with the engaging member 111 . Then, lowered being driven the elevation drive mechanisms 115 , the engaging member 111 is causes the pins 114 to disengage from the plural pallets 108 .
- the elevation drive mechanisms 115 and the engaging member 111 supported by them go back along the conveying path and the engaging member 111 and return to the initial positions.
- pallets 108 are conveyed intermittently along the conveying path.
- the sealing material 120 is a long film made of a thermoplastic resin
- the supplying unit 102 includes a row material roll 121 which is wound with the sealing material 120 , a take-up roll 122 for taking up the sealing material 120 from the row material roll 121 , and plural auxiliary rolls 123 .
- the row material roll 121 and the take-up roll 122 are driven by respective motors (not shown). This is not to control feeding of the sealing material 120 but to prevent loosening of the sealing material 120 by applying prescribed tension to it.
- the plural auxiliary rolls 123 Disposed between the row material roll 121 and the take-up roll 122 as appropriate, the plural auxiliary rolls 123 define a sealing material feeding path.
- An interval of the sealing material feeding path is parallel with the pallet conveying path, and in that interval the sealing material 120 is placed on the outside surfaces 4 a of the bottom plates 4 of the containers 1 mounted on pallets 108 .
- the pouring unit 104 is disposed upstream of the interval, parallel with the pallet conveying path, of the sealing material feeding path.
- the pouring unit 104 includes dispensers 140 and a sensor (not shown).
- the pouring unit 104 detects the pallet 108 with the sensor and pours fluid 12 into the containers 1 mounted on the pallet 108 by causing the dispensers 140 to operate on the basis of a detection signal of the sensor.
- the joining unit 105 is disposed in the interval, parallel with the pallet conveying path, of the sealing material feeding path.
- the joining unit 105 includes a heat welding head 150 which is elevated and lowered and a sensor (not shown).
- the joining unit 105 detects the pallet 108 with the sensor and lowers the heat welding head 150 on the basis of a detection signal of the sensor.
- the sealing material 120 is pressed against the containers 1 mounted on the pallet 108 by means of the heat welding head 150 being lowered and is thereby welded to the outside surfaces 4 a of the bottom plates 4 of the containers 1 .
- the openings 5 of each container 1 are thus sealed.
- the method for joining the sealing material 120 to the outside surface 4 a of the bottom plate 4 of each container 1 is not limited to welding.
- the sealing material 12 Q may be joined to the outside surface 4 a of the bottom plate 4 of each container 1 with adhesive that is applied to the outside surface 4 a of the bottom plate 4 .
- adhesive is applied to the outside surfaces 4 a of the bottom plates 4 of the containers 1 upstream of the interval, parallel with the pallet conveying path, of the sealing material feeding path.
- the cut-out unit 106 is disposed downstream of the joining unit 105 in the interval, parallel with the pallet conveying path, of the sealing material feeding path.
- the cut-out unit 106 includes a laser marker 160 and a sensor (not shown).
- the cut-out unit 106 detects the pallet 108 with the sensor and causes the laser marker 160 to operate on the basis of a detection signal of the sensor.
- the laser marker 160 applies laser light to the sealing material 120 which is welded to the containers 1 mounted on the pallet 108 .
- the laser light is applied along the edge of the outside surface 4 a of the bottom plate 4 of each container 1 .
- second sealing members 11 are cut out of the sealing material 120 in a state that they are welded to the outside surfaces 4 a of the bottom plates 4 of the containers 1 .
- second sealing members 11 may be punched out of the sealing material 120 by pressing a punch against the pallet 108 which serves as a die.
- the separating unit 107 is disposed downstream of the cut-out unit 106 and defines the downstream end of the interval, parallel with the pallet conveying path, of the sealing material feeding path.
- the separating unit 107 includes a slide contact member 170 which is in slide contact with the sealing material 120 and a roll 171 which is disposed downstream of the slide contact member 170 and guides the sealing material 120 upward.
- the sealing material 120 is bent upward immediately downstream of the slide contact member 170 and goes away from the conveying path, the second sealing members 11 that have been punched out of the sealing material 120 move along the pallet conveying path because they are joined to the containers 1 . As a result, relative movements occur between the second sealing members 11 and the other part of the sealing material 120 and the second sealing members 11 are separated from the other part of the sealing material 120 .
- the feeding unit 103 is disposed between the joining unit 105 and the cut-out unit 106 in the pallet conveying path.
- the feeding unit 103 includes a pair of gripping mechanisms 130 which are disposed on both sides of the sealing material 120 and grip or release edge portions of the sealing material 120 .
- the gripping mechanisms 130 are fixed to one of the elevation drive mechanisms 115 which are reciprocation-driven along the conveying path by the translation drive mechanism 116 in the conveying unit 101 , and are moved together with the one elevation drive mechanism 115 .
- the gripping mechanisms 130 grip the sealing material 120 when the engaging member 111 which is engaged with pallets 108 and the elevation drive mechanisms 115 which support the engaging member 111 go forward to convey the pallets 108 in each pallet conveying cycle of the conveying unit 101 .
- the gripping mechanisms 130 go forward together with the one elevation drive mechanism 115 , the sealing material 120 which is gripped by the gripping mechanisms 130 is fed in the sealing material feeding path.
- the feeding unit 103 causes the gripping mechanisms 130 to release the sealing material 120 .
- the gripping mechanisms 130 go back together with the one elevation drive mechanism 115 and returns to the initial position.
- the sealing material 120 is fed intermittently along the sealing material feeding path.
- the feeding unit 103 is moved together with the conveying unit 101 while holding the sealing material 120 .
- the feeding of the sealing material 120 and the conveyance of pallets 108 can easily be synchronized with each other from joining of the sealing material 120 to the containers 1 mounted on the pallets 108 to separation of joined portions (second sealing members 11 ).
- the feeding unit 103 holds the sealing material 120 in the interval, between the joining unit 105 and the cut-out unit 106 , of the pallet conveying path, and can thereby prevent a phenomenon that the feeding of the sealing material 120 and the conveyance of pallets 108 fall out of synchronism with each other in the interval between the joining unit 105 and the cut-out unit 106 due to expansion of the sealing material 120 .
- the feeding unit 103 needs to have plural pairs of gripping mechanisms 130 .
- the conveying unit 101 conveys pallets 108 by reciprocation-driving, along the pallet conveying path, the engaging member 111 which is engaged with pallets 108 in a disengageable manner and the elevation drive mechanisms 115 which support the engaging member 111 , as described above it suffices to dispose the pair of gripping mechanisms 130 .
- the machine configuration can thus be simplified.
- the gripping mechanisms 130 grip the sealing material 120 only while pallets 108 exist in the interval, between the joining unit 105 and the cut-out unit 106 , of the pallet conveying path. Whether or not pallets 108 exist in the interval between the joining unit 105 and the cut-out unit 106 is judged by, for example, counting the number of pallets 108 that have passed the joining unit 105 and the number of pallets 108 that have passed the cut-out unit 106 using sensors provided in the joining unit 105 and the cut-out unit 106 , respectively, and comparing the two numbers.
- FIGS. 9A-9D illustrate a process of sealing plural containers 1 sequentially using the container sealing machine 100 having the above configuration.
- FIGS. 9A-9D show a state that two pallets 108 a and 108 b of plural pallets 108 being conveyed have a long interval P which is longer than the distance L between the joining unit 105 and the cut-out unit 106 as measured along the pallet conveying path. Such a state may occur in, for example, a case that pallets 108 are supplied to the container sealing machine 100 manually.
- FIGS. 9A-9D are simplified in that only the two pallets 108 a and 108 b having the long interval P are shown.
- the pallets 108 a and 108 b are conveyed by the conveying unit 101 which operates cyclically in the above-described manner.
- the pallet 108 a is located in the interval, between the joining unit 105 and the cut-out unit 106 , of the pallet conveying path. Therefore, the gripping mechanisms 130 of the feeding unit 103 grip the sealing material 120 as the engaging member 111 and the elevation drive mechanisms 115 which support the engaging member 111 go forward to convey the pallet 108 a in one pallet conveying cycle of the conveying unit 101 .
- the gripping mechanisms 130 go forward together with the one elevation drive mechanism 115 , the sealing material 120 gripped by the gripping mechanisms 130 is fed along the sealing material feeding path.
- the gripping mechanisms 130 which are holding the sealing material 120 move together with the one of the elevation drive mechanisms 115 which are conveying the pallet 108 a , the feeding of the sealing material 120 is synchronized with the conveyance of the pallet 108 a reliably. As a result, the sealing material 120 can be prevented from being peeled off a container 1 mounted on the pallet 108 a (see FIG. 9B ).
- the above-described cycle is performed repeatedly by the conveying unit 101 , whereby the leading pallet 108 a comes to be located under the cut-out unit 106 .
- Second sealing members 11 are cut out of the sealing material 120 in a state that they are welded to the containers 1 .
- the sealing of the containers 1 mounted on the pallet 108 is thus completed.
- the interval P between the pallets 108 a and 108 b is longer than the distance L between the joining unit 105 and the cut-out unit 106 as measured along the pallet conveying path. Therefore, at a time point when the leading pallet 108 a is located under the cut-out unit 106 , the following pallet 108 h is located upstream of the joining unit 105 along the pallet conveying path (see FIG. 9C ).
- the pallet 108 b is conveyed to under the joining unit 105 as the conveying unit 101 repeats the above-described cycle further.
- No pallet 108 exists in the interval, between the joining unit 105 and the cut-out unit 106 , of the pallet conveying path until the pallet 108 b reaches the position of the joining unit 105 . Therefore, until the pallet 108 b reaches the position of the joining unit 105 , the gripping mechanisms 130 do not grip the sealing material 120 (i.e., the sealing material 120 is kept released) while the engaging member 111 which is engaged with the pallets 108 and the elevation drive mechanisms 115 which support the engaging member 111 go forward in the pallet conveying cycles of the conveying unit 101 to convey the pallets 108 .
- the gripping mechanisms 130 go forward together with the one elevation drive mechanism 115 , the sealing material 120 is not fed along the sealing material feeding path. That is, only the pallets 108 a and 108 b are moved. The sealing material 120 is thus saved (see FIG. 90 ).

Description
- This application claims the benefit of Japanese Patent Application JP 2010-192985, filed Aug. 30, 2010 and Japanese Patent Application JP 2011-035225, filed Feb. 21, 2011, the entire contents of which are hereby incorporated by reference, the same as if set forth at length.
- The present invention relates to a container which contains fluid such as liquid or a gel-like body, a portion package in which fluid is sealed in the container, a manufacturing method of the portion package, and an opening method of the portion package.
- Portion packages are known in which fluid such as liquid or a gel-like body (contents) is sealed in a container (refer to JP-UM-A-56-141173 and JP-T-2003-512107 (The symbol “JP-T” as used herein means a published Japanese translation of a PCT patent application.), for example).
- A portion package container disclosed in JP-UM-A-56-141173 is provided with a pipe-shaped container body which is open at one end and has a bottom at the other end. The bottom of the container body is formed with a discharge hole for discharging the fluid contained. The open end of the container body is sealed with a sealing member that is fitted in the open end, and the bottom discharge hole is sealed with a lid member that covers the bottom end. Fluid is poured into the container through its open end in a state that the discharge hole is sealed with the lid member, and sealed in the container by fitting the sealing member into the open end.
- A portion package container disclosed in JP-T-2003-512107 is provided with a pipe-shaped container body which is open at both ends. Each open end of the container body is sealed by welding a film-Like sealing member to the end surface. Fluid is poured into the container through one open end in a state that the other open end is sealed with the sealing member, and sealed in the container by welding the sealing member to the end surface of the one open end.
- In each of the portion packages disclosed in JP-UM-A-56-141173 and JP-T-2003-512107, the open end or one of the open ends serves as an opening for fluid pouring. With this structure, it is difficult to pour fluid into the container so as to fill it up.
- As for fluid that has been poured into a container, surface tension makes a peripheral portion of the surface of the fluid higher than a central portion. Even if a peripheral portion of the surface of the fluid is in contact with the edge of an open end, a central portion of the surface of the fluid is lower than the peripheral portion. As a result, the amount of poured fluid is insufficient. Where an open end is used as an opening for pouring, the pouring opening is necessarily made large and a rise of a peripheral portion of the surface of fluid makes the amount of pouring of fluid more insufficient as the pouring opening becomes larger. If fluid is poured further, a peripheral portion of the surface of the fluid may pass the edge of the open end and expand to wet the end surface. Having a relatively small area, the end surface is easily covered with the expanding fluid. In the case of a container in which the open end serving as a poring opening is sealed by welding a sealing member to the end surface of the open end, the above phenomenon may obstruct joining of the sealing member to the end surface of the open end and thereby render the sealing of the open end with the sealing member incomplete.
- The present invention has been made in the above circumstances, and an object of the present invention is therefore to facilitate charging of a portion package container with fluid and to enable reliable sealing of its pouring opening (or holes) with a sealing member.
- (1) A container comprising a container body having a short pipe shape in which one end is open and the other end is provided with a bottom plate which is formed with a pouring hole in a partial region; and a first sealing member which is joined to an end surface of an open end of the container body and thereby seals the open end.
- (2) A portion package comprising the container of item (1); fluid contained in the container; and a second sealing member which is joined to an outside surface of the bottom plate and thereby seals the pouring hole.
- (3) A manufacturing method of a portion package, comprising the steps of pouring fluid through a pouring hole into a short-pipe-shaped container in which one, open end is sealed with a first sealing member and a bottom plate which is provided at the other end is formed with the pouring hole; and sealing the pouring hole by joining a second sealing member to an outside surface of the bottom plate of the container into which the fluid has been poured.
- According to the invention, one end of the container body is provided with the bottom plate which is formed with the pouring hole in a partial region. Therefore, the surface of fluid that has been poured into the container is flattened by means of the bottom plate. In this manner, the container can be charged with fluid easily.
- Since the first sealing member is joined to the end surface of the open end of the container body to seal the open end before pouring of fluid, fluid being poured does not obstruct joining of the first sealing member to the open end of the container body. The second sealing member is joined to the outside surface of the bottom plate having the pouring hole to seal the pouring hole after pouring of fluid. And the outside surface of the bottom plate is wider than an end surface that would be obtained if the bottom-plate-side end of the container body were an open end. Therefore, even if fluid expands to wet a portion around the pouring hole, a joining region can be obtained on the outside surface of the bottom plate outside that portion so as to surround the pouring hole. The pouring hole can thus be sealed reliably with the second sealing member.

FIGS. 1 and 2 show a container according to an embodiment of the present invention. - The
container 1 is provided with acontainer body 2 and afirst sealing member 3. - The
container body 2 is shaped like a short pipe, and its one end is open and the other end is provided with abottom plate 4. Thebottom plate 4 is formed withopenings 5. In the illustrated example, thecontainer body 2 is shaped like a short pipe that is generally rectangular in a plan view and theopenings 5 occupy four corner portions of thebottom plate 4 and are generally circular in a plan view. When fluid is poured into thecontainer 1, part of theopenings 5 may serve as pouring holes with theother openings 5 used as outlets for venting air out of thecontainer 1. - Furthermore, the
outside surface 4 a of thebottom plate 4 is formed with pluralannular ribs 6, each of which is formed so as to surround the associatedopening 5 and to be distant from the edge of the associatedopening 5 and the associated portion of the edge of theoutside surface 4 a of thebottom plate 4. The distance between eachrib 6 and the associatedopening 5 is set so thatfluid 12 that overflows thecontainer 1 after its capacity is reached is contained inside eachrib 6 taking into consideration a variation of a pouring amount offluid 12 when it is poured into thecontainer 1 using a dispenser or the like. - The first sealing
member 3 is joined to anend surface 7 a of anopen end 7 of thecontainer body 2, whereby theopen end 7 is sealed. The first sealingmember 3 is formed by, for example, laminating a metal foil of aluminum or the like on the surface of a thermoplastic resin film, and is typically welded to theend surface 7 a of theopen end 7. However, the method for joining thefirst sealing member 3 to theend surface 7 a of theopen end 7 is not limited to welding. For example, thefirst sealing member 3 may be joined to theend surface 7 a of theopen end 7 with adhesive that is applied to theend surface 7 a of theopen end 7. Therefore, thefirst sealing member 3 is not limited to weldable members. -
FIG. 3 shows an example portion package in whichfluid 12 is sealed in thecontainer 1. - The
portion package 10 is configured in such a manner that asecond sealing member 11 is joined to theoutside surface 4 a of thebottom plate 4 of thecontainer 1 which is filled with the fluid 12 and all of theopenings 5 of thebottom plate 4 are sealed. The fluid 12 has been poured into thecontainer 1 until its capacity is reached substantially and is sealed in thecontainer 1. - The
second sealing member 11 is formed by, for example, laminating a metal foil of aluminum or the like on the surface of a thermoplastic resin film, and is typically welded to theoutside surface 4 a of thebottom plate 4 of thecontainer 1. However, the method for joining the second sealingmember 11 to theoutside surface 4 a of thebottom plate 4 is not limited to welding. For example, the second sealingmember 11 may be joined to theoutside surface 4 a of thebottom plate 4 with adhesive that is applied to theoutside surface 4 a of thebottom plate 4. Therefore, the second sealingmember 11 is not limited to weldable members. -
FIGS. 4A-4D illustrate a manufacturing process of theportion package 10. -
Fluid 12 is poured through theopenings 5 of thebottom plate 4 into thecontainer 1 whoseopen end 7 is sealed with thefirst sealing member 3.Fluid 12 is poured by approximately a prescribed amount using a dispenser, for example. The fluid 12 that has been poured into thecontainer 1 has a concave surface, that is, because of its surface tension, aperipheral portion 12 a of its surface that is in contact with the inside surface of the side wall of thecontainer 1 is higher than acentral portion 12 b (seeFIG. 4A ). - After the
peripheral portion 12 a of the fluid 12 has reached theinside surface 4 b of thebottom plate 4 of thecontainer 1, theperipheral portion 12 a remains there even iffurther fluid 12 is poured into thecontainer 1. On the other hand, since a space exists between thecentral portion 12 b of the surface of the fluid 12 and theinside surface 4 b of thebottom plate 4, thecentral portion 12 b rises gradually and comes into contact with theinside surface 4 b of thebottom plate 4 asfurther fluid 12 is poured into thecontainer 1. That is, the surface of the fluid 12, which has been concave, is flattened by means of theinside surface 4 b of thebottom plate 4. Thecontainer 1 is thus filled with the fluid 12 (seeFIGS. 4B and 4C ). - Then, the second sealing
member 11 is joined to theoutside surface 4 a of thebottom plate 4. All of theopenings 5 of thebottom plate 4 are sealed with the second sealingmember 11, whereby the fluid 12 is sealed in the container 1 (seeFIG. 4D ). -
FIG. 5 illustrates, in detail, a joining state of thecontainer 1 and the second sealingmember 11 around oneopening 5. - Because of a variation of the amount of fluid pouring by a dispenser and other factors, fluid 12 that overflows the
container 1 after its capacity is reached may expand to wet the portion, around eachopening 5, of theoutside surface 4 a of thebottom plate 4.FIG. 5 shows a state that fluid 12 has expanded to wet the portion around theopening 5. - The
second sealing member 11 is joined to theoutside surface 4 a of thebottom plate 4 in a state that fluid 12 has expanded to wet the portion around eachopening 5. Since theoutside surface 4 a of thebottom plate 4 is wider than an end surface that would be obtained if the bottom-4-side end of thecontainer 1 were an open end, even iffluid 12 expands to wet the portion around eachopening 5, a joining region can be formed between theoutside surface 4 a of thebottom plate 4 and the second sealingmember 11 outside that portion so as to surround eachopening 5. - In particular, the
outside surface 4 a of thebottom plate 4 is formed with the pluralannular ribs 6 and eachrib 6 surrounds the associatedopening 5 so as to be distant from the edge of the associatedopening 5. And eachrib 6 is distant from the associated portion of the edge of theoutside surface 4 a of thebottom plate 4. Therefore, expandingfluid 12 is dammed up by eachrib 6 and a joining region can be secured outside eachrib 6 so as to surround the associatedopening 5. - As described above, when the second sealing
member 11 is joined to theoutside surface 4 a of thebottom plate 4, eachopening 5 is surrounded by a joining region of the second sealingmember 11 and theoutside surface 4 a of thebottom plate 4, whereby theopenings 5 can be sealed reliably with the second sealingmember 11. -
FIGS. 6A-6C illustrate an example opening tool for theportion package 10 and an example process of opening theportion package 10 using the opening tool. - The
opening tool 20 is equipped with aprojection 22 which is provided on the top surface of asubstrate 21 at the center and asharp nail 23 which projects from a portion of the edge of the top surface of theprojection 22. Theprojection 22 can be inserted into thecontainer 1 from theopen end 7 side of thecontainer 1 of theportion package 10 and, when inserted, fitted in thecontainer 1 loosely. - The
first sealing member 3 with which theopen end 7 of thecontainer 1 of theportion package 10 is sealed is pressed against theprojection 22 and perforated by thenail 23 of the top surface of the projection 22 (seeFIG. 6A ). - The
first sealing member 3 continues to be pressed against theprojection 22, whereby thefirst sealing member 3 is broken starting from the hole formed by thenail 23 and theportion package 10 is opened. Theprojection 22 is inserted into thecontainer 1. The fluid 12 that has been sealed in theportion package 10 pressed out by theprojection 22. The pressed-outfluid 12 is received by thesubstrate 21 and collected (seeFIG. 6B ). - When the
projection 22 is inserted fully into thecontainer 1, the inside space of thecontainer 1 is occupied by theprojection 22, whereby the fluid 12 that was sealed in theportion package 10 can be collected substantially in its entirety (seeFIG. 6C ). -
FIGS. 7 and 8 show an example container sealing machine for sealing theopenings 5 of thecontainer 1. - The sealing
machine 100 seals theopenings 5 of thecontainer 1 by joining the second sealingmember 11 to theoutside surface 4 a of thebottom plate 4 of thecontainer 1.Plural containers 1 are arranged on eachpallet 108 andcontainers 1 are supplied to the sealingmachine 100 on a pallet-by-pallet basis.FIG. 7 is simplified in that only onecontainer 1 is shown for eachpallet 108. - The sealing
machine 100 is equipped with aconveyor 101 for conveyingpallets 108 on whichcontainers 1 are arranged, a supplyingunit 102 for supplying a sealingmaterial 120 which is a material ofsecond sealing members 11, afeeding unit 103 for feeding the sealingmaterial 120 supplied from the supplyingunit 102, a pouringunit 104 for pouring fluid intocontainers 1, a joiningunit 105 for joining part of the sealingmaterial 120 to eachcontainer 1 mounted on eachpallet 108, a cut-outunit 106 for cutting a joined portion (second sealing member 11) that has been joined to eachcontainer 1 on eachpallet 108 out of the sealingmaterial 120, and aseparating unit 107 for separating the cut-out joined portion (second sealing member 11) from the other part of the sealingmaterial 120. - The
conveyor 101 includes aguide rail 110 which extends along a pallet conveying path, an engagingmember 111 for engaging withplural pallets 108 which are to engage withpallets 108 mounted on theguide rail 110 in a disengageable manner, and adrive mechanism 112 for driving the engagingmember 111. - The engaging
member 111 has a base 113 which is disposed under and extends parallel with theguide rail 110 andplural pins 114 which are erected from the base 113 with a prescribed pitch. - The
drive mechanism 112 haselevation drive mechanisms 115 such as cylinder-piston units which support and drive (i.e., elevate and lower) the engagingmember 111 and atranslation drive mechanism 116 such as a linear motor which reciprocation-drives theelevation drive mechanisms 115 in the pallet conveying path. - When elevated being driven the
elevation drive mechanisms 115, the engagingmember 111 causes thepins 114 to engage withplural pallets 108 mounted on theguide rail 110. Then, driven by thetranslation drive mechanism 116, theelevation drive mechanisms 115 and the engagingmember 111 supported by them go forward along the conveying path and theplural pallets 108 which are engaged with thepins 114 go forward on theguide rails 110 together with the engagingmember 111. Then, lowered being driven theelevation drive mechanisms 115, the engagingmember 111 is causes thepins 114 to disengage from theplural pallets 108. Subsequently, driven by thetranslation drive mechanism 116, theelevation drive mechanisms 115 and the engagingmember 111 supported by them go back along the conveying path and the engagingmember 111 and return to the initial positions. As the above cycle is performed repeatedly,pallets 108 are conveyed intermittently along the conveying path. - The sealing
material 120 is a long film made of a thermoplastic resin, and the supplyingunit 102 includes arow material roll 121 which is wound with the sealingmaterial 120, a take-up roll 122 for taking up the sealingmaterial 120 from therow material roll 121, and plural auxiliary rolls 123. - The
row material roll 121 and the take-up roll 122 are driven by respective motors (not shown). This is not to control feeding of the sealingmaterial 120 but to prevent loosening of the sealingmaterial 120 by applying prescribed tension to it. - Disposed between the
row material roll 121 and the take-up roll 122 as appropriate, the plural auxiliary rolls 123 define a sealing material feeding path. An interval of the sealing material feeding path is parallel with the pallet conveying path, and in that interval the sealingmaterial 120 is placed on theoutside surfaces 4 a of thebottom plates 4 of thecontainers 1 mounted onpallets 108. - In the pallet conveying path, the pouring
unit 104 is disposed upstream of the interval, parallel with the pallet conveying path, of the sealing material feeding path. The pouringunit 104 includesdispensers 140 and a sensor (not shown). When apallet 108 being conveyed is located under the pouringunit 104, the pouringunit 104 detects thepallet 108 with the sensor and pours fluid 12 into thecontainers 1 mounted on thepallet 108 by causing thedispensers 140 to operate on the basis of a detection signal of the sensor. - In the pallet conveying path, the joining
unit 105 is disposed in the interval, parallel with the pallet conveying path, of the sealing material feeding path. The joiningunit 105 includes aheat welding head 150 which is elevated and lowered and a sensor (not shown). - When a
pallet 108 being conveyed is located under the joiningunit 105, the joiningunit 105 detects thepallet 108 with the sensor and lowers theheat welding head 150 on the basis of a detection signal of the sensor. The sealingmaterial 120 is pressed against thecontainers 1 mounted on thepallet 108 by means of theheat welding head 150 being lowered and is thereby welded to theoutside surfaces 4 a of thebottom plates 4 of thecontainers 1. Theopenings 5 of eachcontainer 1 are thus sealed. The method for joining the sealingmaterial 120 to theoutside surface 4 a of thebottom plate 4 of eachcontainer 1 is not limited to welding. For example, the sealing material 12Q may be joined to theoutside surface 4 a of thebottom plate 4 of eachcontainer 1 with adhesive that is applied to theoutside surface 4 a of thebottom plate 4. In this case, for example, in the pallet conveying path, adhesive is applied to theoutside surfaces 4 a of thebottom plates 4 of thecontainers 1 upstream of the interval, parallel with the pallet conveying path, of the sealing material feeding path. - The cut-out
unit 106 is disposed downstream of the joiningunit 105 in the interval, parallel with the pallet conveying path, of the sealing material feeding path. The cut-outunit 106 includes alaser marker 160 and a sensor (not shown). - When a
pallet 108 being conveyed is located under the cut-outunit 106, the cut-outunit 106 detects thepallet 108 with the sensor and causes thelaser marker 160 to operate on the basis of a detection signal of the sensor. Thelaser marker 160 applies laser light to the sealingmaterial 120 which is welded to thecontainers 1 mounted on thepallet 108. The laser light is applied along the edge of theoutside surface 4 a of thebottom plate 4 of eachcontainer 1. As a result,second sealing members 11 are cut out of the sealingmaterial 120 in a state that they are welded to theoutside surfaces 4 a of thebottom plates 4 of thecontainers 1. Alternatively,second sealing members 11 may be punched out of the sealingmaterial 120 by pressing a punch against thepallet 108 which serves as a die. - The separating
unit 107 is disposed downstream of the cut-outunit 106 and defines the downstream end of the interval, parallel with the pallet conveying path, of the sealing material feeding path. The separatingunit 107 includes aslide contact member 170 which is in slide contact with the sealingmaterial 120 and aroll 171 which is disposed downstream of theslide contact member 170 and guides the sealingmaterial 120 upward. - Whereas the sealing
material 120 is bent upward immediately downstream of theslide contact member 170 and goes away from the conveying path, thesecond sealing members 11 that have been punched out of the sealingmaterial 120 move along the pallet conveying path because they are joined to thecontainers 1. As a result, relative movements occur between thesecond sealing members 11 and the other part of the sealingmaterial 120 and thesecond sealing members 11 are separated from the other part of the sealingmaterial 120. - The
feeding unit 103 is disposed between the joiningunit 105 and the cut-outunit 106 in the pallet conveying path. Thefeeding unit 103 includes a pair ofgripping mechanisms 130 which are disposed on both sides of the sealingmaterial 120 and grip or release edge portions of the sealingmaterial 120. Thegripping mechanisms 130 are fixed to one of theelevation drive mechanisms 115 which are reciprocation-driven along the conveying path by thetranslation drive mechanism 116 in the conveyingunit 101, and are moved together with the oneelevation drive mechanism 115. - The
gripping mechanisms 130 grip the sealingmaterial 120 when the engagingmember 111 which is engaged withpallets 108 and theelevation drive mechanisms 115 which support the engagingmember 111 go forward to convey thepallets 108 in each pallet conveying cycle of the conveyingunit 101. As thegripping mechanisms 130 go forward together with the oneelevation drive mechanism 115, the sealingmaterial 120 which is gripped by the grippingmechanisms 130 is fed in the sealing material feeding path. When the engagingmember 111 which has been disengaged from thepallets 108 and theelevation drive mechanisms 115 which support the engagingmember 111 go back and return to the initial positions, thefeeding unit 103 causes thegripping mechanisms 130 to release the sealingmaterial 120. Thegripping mechanisms 130 go back together with the oneelevation drive mechanism 115 and returns to the initial position. As the above-described cycle is performed repeatedly, the sealingmaterial 120 is fed intermittently along the sealing material feeding path. As described above, in feeding the sealingmaterial 120, thefeeding unit 103 is moved together with the conveyingunit 101 while holding the sealingmaterial 120. As a result, the feeding of the sealingmaterial 120 and the conveyance ofpallets 108 can easily be synchronized with each other from joining of the sealingmaterial 120 to thecontainers 1 mounted on thepallets 108 to separation of joined portions (second sealing members 11). - The
feeding unit 103 holds the sealingmaterial 120 in the interval, between the joiningunit 105 and the cut-outunit 106, of the pallet conveying path, and can thereby prevent a phenomenon that the feeding of the sealingmaterial 120 and the conveyance ofpallets 108 fall out of synchronism with each other in the interval between the joiningunit 105 and the cut-outunit 106 due to expansion of the sealingmaterial 120. - It is possible to convey
pallets 108 using a belt conveyor. However, since each portion of a belt returns to the initial position after a circulation, to conveypallets 108 continuously and feed the sealingmaterial 120 in synchronism with the conveyance of thepallets 108, thefeeding unit 103 needs to have plural pairs of grippingmechanisms 130. In contrast, in the configuration in which the conveyingunit 101 conveyspallets 108 by reciprocation-driving, along the pallet conveying path, the engagingmember 111 which is engaged withpallets 108 in a disengageable manner and theelevation drive mechanisms 115 which support the engagingmember 111, as described above it suffices to dispose the pair ofgripping mechanisms 130. The machine configuration can thus be simplified. - In the
feeding unit 103, the grippingmechanisms 130 grip the sealingmaterial 120 only whilepallets 108 exist in the interval, between the joiningunit 105 and the cut-outunit 106, of the pallet conveying path. Whether or notpallets 108 exist in the interval between the joiningunit 105 and the cut-outunit 106 is judged by, for example, counting the number ofpallets 108 that have passed the joiningunit 105 and the number ofpallets 108 that have passed the cut-outunit 106 using sensors provided in the joiningunit 105 and the cut-outunit 106, respectively, and comparing the two numbers. -
FIGS. 9A-9D illustrate a process of sealingplural containers 1 sequentially using thecontainer sealing machine 100 having the above configuration. -
FIGS. 9A-9D show a state that twopallets plural pallets 108 being conveyed have a long interval P which is longer than the distance L between the joiningunit 105 and the cut-outunit 106 as measured along the pallet conveying path. Such a state may occur in, for example, a case thatpallets 108 are supplied to thecontainer sealing machine 100 manually.FIGS. 9A-9D are simplified in that only the twopallets - When the leading
pallet 108 a is located under the joiningunit 105, a sealingmaterial 120 is welded to thecontainers 1 mounted on thepallet 108 a. As a result, theopenings 5 of thecontainers 1 are sealed (seeFIG. 9A ). - Then, the
pallets unit 101 which operates cyclically in the above-described manner. Thepallet 108 a is located in the interval, between the joiningunit 105 and the cut-outunit 106, of the pallet conveying path. Therefore, the grippingmechanisms 130 of thefeeding unit 103 grip the sealingmaterial 120 as the engagingmember 111 and theelevation drive mechanisms 115 which support the engagingmember 111 go forward to convey thepallet 108 a in one pallet conveying cycle of the conveyingunit 101. As thegripping mechanisms 130 go forward together with the oneelevation drive mechanism 115, the sealingmaterial 120 gripped by the grippingmechanisms 130 is fed along the sealing material feeding path. Since thegripping mechanisms 130 which are holding the sealingmaterial 120 move together with the one of theelevation drive mechanisms 115 which are conveying thepallet 108 a, the feeding of the sealingmaterial 120 is synchronized with the conveyance of thepallet 108 a reliably. As a result, the sealingmaterial 120 can be prevented from being peeled off acontainer 1 mounted on thepallet 108 a (seeFIG. 9B ). - The above-described cycle is performed repeatedly by the conveying
unit 101, whereby the leadingpallet 108 a comes to be located under the cut-outunit 106.Second sealing members 11 are cut out of the sealingmaterial 120 in a state that they are welded to thecontainers 1. The sealing of thecontainers 1 mounted on thepallet 108 is thus completed. The interval P between thepallets unit 105 and the cut-outunit 106 as measured along the pallet conveying path. Therefore, at a time point when the leadingpallet 108 a is located under the cut-outunit 106, the following pallet 108 h is located upstream of the joiningunit 105 along the pallet conveying path (seeFIG. 9C ). - The
pallet 108 b is conveyed to under the joiningunit 105 as the conveyingunit 101 repeats the above-described cycle further. Nopallet 108 exists in the interval, between the joiningunit 105 and the cut-outunit 106, of the pallet conveying path until thepallet 108 b reaches the position of the joiningunit 105. Therefore, until thepallet 108 b reaches the position of the joiningunit 105, the grippingmechanisms 130 do not grip the sealing material 120 (i.e., the sealingmaterial 120 is kept released) while the engagingmember 111 which is engaged with thepallets 108 and theelevation drive mechanisms 115 which support the engagingmember 111 go forward in the pallet conveying cycles of the conveyingunit 101 to convey thepallets 108. Although thegripping mechanisms 130 go forward together with the oneelevation drive mechanism 115, the sealingmaterial 120 is not fed along the sealing material feeding path. That is, only thepallets material 120 is thus saved (seeFIG. 90 ). -
FIG. 10 shows a container according to another embodiment. Members etc. having the same ones in the above-describedcontainer 1 will be given the same reference symbols as the latter and will be described in a simplified manner or will not be described at all. - The
container 31 is provided with acontainer body 32 and afirst sealing member 3. - The
container body 32 is shaped like a short pipe, and its one end is open and the other end is provided with abottom plate 34. Thebottom plate 34 is formed withopenings 35. In the illustrated example, thecontainer body 32 is shaped like a short pipe that is generally rectangular in a plan view and theopenings 35 occupy two diagonal corner portions of thebottom plate 34 and are generally circular in a plan view. When fluid is poured into thecontainer 31, one of the twoopenings 35 serves as a pouring hole and theother opening 35 serves as an outlet for venting air out of thecontainer 31. - Each
opening 35 has a step-like shape in which the opening diameter φ2 of asecond end portion 35 b that is connected to theoutside surface 34 a of thebottom plate 34 is larger than the opening diameter φ1 of afirst end portion 35 a that is connected to theinside surface 34 b of thebottom plate 34. Thefirst end portion 35 a and thesecond end portion 35 b are connected by ahorizontal surface 38. The opening diameter φ2 of thesecond end portion 35 b is set so that fluid 12 that overflows thecontainer 31 after its capacity is reached is contained inside eachsecond end portion 35 b taking into consideration a variation of a pouring amount offluid 12 when it is poured into thecontainer 31 using a dispenser or the like. - The
first sealing member 3 is joined to anend surface 37 a of anopen end 37 of thecontainer body 32, whereby theopen end 37 is sealed. -
FIG. 11 shows an example portion package in whichfluid 12 is sealed in thecontainer 31. - The
portion package 40 is configured in such a manner that asecond sealing member 11 is joined to theoutside surface 34 a of thebottom plate 34 of thecontainer 31 which is filled with the fluid 12 and bothopenings 35 of thebottom plate 34 are sealed. The fluid 12 has been poured into thecontainer 31 until its capacity is reached substantially and is sealed in thecontainer 31. Thesecond sealing member 11 is joined to theoutside surface 34 a of the bottom plate 39 of thecontainer 31 by welding. -
FIG. 12 illustrates, in detail, a joining state of thecontainer 31 and the second sealingmember 11 around oneopening 35. - Because of a variation of the amount of fluid pouring by a dispenser and other factors, fluid 12 that overflows the
container 31 after its capacity is reached may enter theopenings 35.FIG. 12 shows a state that fluid 12 has entered theopenings 35. - As described above, each opening 35 has the step-like shape in which the opening diameter φ2 of the
second end portion 35 b that is connected to theoutside surface 34 a of thebottom plate 34 is larger than the opening diameter φ1 of thefirst end portion 35 a that is connected to theinside surface 34 b of thebottom plate 34. Thefirst end portion 35 a and thesecond end portion 35 b are connected by thehorizontal surface 38.Fluid 12 that has entered eachopening 35 merely expands to wet thehorizontal surface 38 and does not expand so as to wet theoutside surface 34 a of thebottom plate 34 of thecontainer 31. A joining region that surrounds eachopening 35 is thus secured in theoutside surface 34 a. - In the above-described
container 1, the regions whereoverflow fluid 12 expands to wet their surfaces are provided on theoutside surface 4 a and those regions are flush with the joining region of the second sealingmember 11 and theoutside surface 4 a of thebottom plate 4. In contrast, in thecontainer 31 according to this embodiment, the regions whereoverflow fluid 12 expands to wet their surfaces correspond to thehorizontal surfaces 38 that are located inside theopenings 35 and hence are not flush with theoutside surface 34 a of thebottom plate 34 where the joining region of the second sealingmember 11 and theoutside surface 34 a of thebottom plate 34 is provided. As a result, the second sealingmember 11 can be joined to theoutside surface 34 a of thebottom plate 34 more reliably. -
FIG. 13 shows a modification of thecontainer 31. - In the
container 31 a shown inFIG. 13 , theoutside surface 34 a of thebottom plate 34 is formed with pluralannular ribs 36. Eachrib 36 is formed around the edge of the associatedopening 35 so as to surround the associatedopening 35. Like theribs 6 of thecontainer 1, theribs 36 have the function of damming up expandingfluid 12. Furthermore, theribs 36 are used as thinning margins when the second sealingmember 11 is welded to seal thecontainer 31 a. Thesecond sealing member 11 is welded to the tip portions of therespective ribs 36. - By virtue of the
ribs 36 serving as thinning margins, formation errors of the individual members of thecontainer 31 a in which thebottom plate 34 is formed with theplural openings 35 and theopenings 35 can be sealed reliably. Furthermore, whenplural containers 31 a are sealed at one time by the above-describedsealing machine 100, formation errors among thecontainers 31 a can be absorbed and thecontainers 31 a can be sealed reliably. - It is preferable that the tip portion of each of the
ribs 36 to which the second sealingmember 11 is welded have a flat surface. This makes it possible to secure sufficient joining areas for welding and to thereby improve the sealing performance. Where the second sealingmember 11 is formed by laminating a metal foil of aluminum or the like on the surface of a thermoplastic resin film, an event that the film is pierced and the laminated metal foil is corroded being exposed to the fluid 12 can be prevented. - As described above, this specification discloses containers of the following items (1)-(6).
- (1) A container comprising a container body having a short pipe shape in which one end is open and the other end is provided with a bottom plate which is formed with a pouring hole; and a first sealing member which is joined to an end surface of an open end of the container body and thereby seals the open end.

- The specification discloses portion packages of the following items (7) and (8).
- (7) A portion package comprising the container of any one of items (1)-(6); fluid contained in the container; and a second sealing member which is joined to an outside surface of the bottom plate and thereby seals the pouring hole.
- (8) A portion package comprising the container of item (3) or (4); fluid contained in the container; and a second sealing member which is joined to the outside surface of the bottom plate so as to be welded to a tip portion of the rib, and thereby seals the pouring hole.
- Furthermore, the specification discloses a manufacturing method of a portion package, comprising the steps of pouring fluid through a pouring hole into a short-pipe-shaped container in which one open end is sealed with a first sealing member and a bottom plate which is provided at the other end is formed with the pouring hole; and sealing the pouring hole by joining a second sealing member to an outside surface of the bottom plate of the container into which the fluid has been poured.
- Still further, the specification discloses an opening method of the portion package of item (7), comprising the steps of breaking the first sealing member; and pushing out the fluid contained in the container by inserting a thing that fits in the container into the container through the open end.
- The specification discloses another opening method of the portion package of item (7), comprising the step of breaking the first sealing member by pressing the first sealing member against a front surface of a thing that fits in the container and is oriented so as to be suitable for insertion into the container.
