　包装袋の収容部に内容物が収容された包装物品では、包装袋の熱溶着部は、主熱溶着部とその主熱溶着部よりも熱溶着強度の低い副熱溶着部とから構成される。収容部の内圧を利用して副熱溶着部を開封することが可能となる。 In a packaged article in which contents are contained in the packaging bag container, the heat-welded part of the packaging bag is composed of a main heat-welded part and a secondary heat-welded part having a lower heat-welding strength than the main heat-welded part. . It is possible to open the auxiliary heat welding part using the internal pressure of the housing part.
　包装物品は、その生産性を高めるために、複数の包装物品が連結された包装物品連結体として製造される場合が多い。こうした包装物品連結体は、輸送され、個々の包装物品に分離されることがある。個々の包装物品は、さらに包装体に収容されることがある。例えば包装物品連結体の輸送の際に収容部に不要な力が加わり、副熱溶着部が開封して内容物が漏れ出すおそれがある。 In many cases, a packaged article is manufactured as a packaged article assembly in which a plurality of packaged articles are linked in order to increase productivity. Such packaged article assemblies may be transported and separated into individual packaged articles. Individual packaged articles may be further accommodated in a package. For example, when the packaged article assembly is transported, an unnecessary force is applied to the housing portion, and the secondary heat welding portion may be opened and the contents may leak out.
　本発明の目的は、包装物品の内容物が漏れ出すことを抑制することのできる包装物品連結体及びその製造方法を提供することにある。
　本発明の一側面に従う包装物品連結体は、第１包装物品と前記第１包装物品に連結された第２包装物品とを含む複数の包装物品を備え、各包装物品は、少なくとも一つの熱溶着部により画定された収容部を有する包装袋を備える。各包装袋の前記少なくとも一つの熱溶着部は、主熱溶着部と、前記主熱溶着部よりも熱溶着強度の低い副熱溶着部とを有し、前記包装袋は、前記副熱溶着部の開封時に内容物が前記収容部から流入する流入部を有し、前記流入部は、各々が前記主熱溶着部又は前記包装袋の折り部により形成される第１側縁と第２側縁とを有し、前記第２包装物品の流入部の下流端が前記第１包装物品の主熱溶着部により封止されている。 The objective of this invention is providing the packaged article coupling body which can suppress that the content of a packaged article leaks, and its manufacturing method.
A packaged article assembly according to one aspect of the present invention includes a plurality of packaged articles including a first packaged article and a second packaged article coupled to the first packaged article, and each packaged article includes at least one heat welded article. A packaging bag having a receiving portion defined by the portion; The at least one heat welding portion of each packaging bag has a main heat welding portion and a sub heat welding portion having a lower heat welding strength than the main heat welding portion, and the packaging bag has the sub heat welding portion. A first side edge and a second side edge each formed by the main heat welding part or the folding part of the packaging bag. And the downstream end of the inflow part of the second packaged article is sealed by the main heat welding part of the first packaged article.
　この構成によれば、第２包装物品の副熱溶着部が開封されることで流入部に内容物が流入したとしても、その内容物の外部への流出は第１包装物品の主熱溶着部により抑制される。 According to this configuration, even if the contents flow into the inflow part by opening the secondary heat welding part of the second packaging article, the outflow of the contents to the outside is the main heat welding part of the first packaging article. It is suppressed by.
　一例では、前記副熱溶着部は、前記流入部と前記収容部との境界に局所的に形成されている。一例では、前記副熱溶着部は、前記主熱溶着部に接続されている。一例では、前記副熱溶着部は、前記主熱溶着部に接続された一端または両端を有するブリッジである。一例では、前記主熱溶着部は、隣接する２つの包装物品の各収容部を部分的に区画し、前記副熱溶着部は、前記２つの包装物品の一方の収容部のみを部分的に区画する。 In one example, the auxiliary heat welding portion is locally formed at the boundary between the inflow portion and the accommodating portion. In one example, the auxiliary heat welding part is connected to the main heat welding part. In one example, the auxiliary heat welding part is a bridge having one end or both ends connected to the main heat welding part. In one example, the main heat welding part partially divides each accommodating part of two adjacent packaging articles, and the auxiliary heat welding part partially divides only one accommodating part of the two packaging articles. To do.
　本発明の別の側面は、包装物品連結体の製造方法に向けられている。この製造方法は、縦方向に連続した中空部分を有する基材に横熱溶着部を形成する横熱溶着工程を備え、前記横熱溶着工程は、前記基材に、第１金型を用いて前記副熱溶着部が形成される条件で第１横熱溶着部を形成する第１サブ段階と、前記第１横熱溶着部を有する前記基材に、第２金型を用いて前記主熱溶着部が形成される条件で第２横熱溶着部を形成する第２サブ段階とを有する。 Another aspect of the present invention is directed to a method for manufacturing a packaged article assembly. This manufacturing method includes a transverse heat welding step of forming a transverse heat welding portion on a base material having a hollow portion continuous in the vertical direction, and the transverse heat welding step uses a first mold on the base material. A first sub-stage for forming the first lateral heat welded part under the conditions for forming the secondary heat welded part, and the main heat using the second mold on the base material having the first lateral heat welded part. And a second sub-stage for forming the second transverse heat weld part under the condition that the weld part is formed.
　この方法によれば、副熱溶着部と主熱溶着部を形成する横熱溶着工程は、第１金型を用いる第１サブ段階及び第２金型を用いる第２サブ段階を有するため、第１サブ段階の条件と第２サブ段階の条件とを別々に設定することができる。このため、副熱溶着部と主熱溶着部のいずれも形成する横熱溶着工程において、熱溶着の条件設定が容易となる。 According to this method, the transverse heat welding process for forming the sub heat welding portion and the main heat welding portion includes the first sub stage using the first mold and the second sub stage using the second mold. The conditions for the first sub-stage and the conditions for the second sub-stage can be set separately. For this reason, in the transverse heat welding process in which both the auxiliary heat welding part and the main heat welding part are formed, it is easy to set conditions for heat welding.
　一例では、前記第１金型は、一対のローラーにそれぞれ設けられ、前記第１横熱溶着部は、前記一対のローラー間で形成され、前記第１金型は、前記第１横熱溶着部を形成するための加熱部と、前記加熱部よりも熱伝導性の低い材料から構成され、前記基材を加圧する低熱伝導部と、を有し、前記加熱部及び低熱伝導部は、前記中空部分を前記基材の流れ方向の上流側と下流側とに仕切るように配置され、前記加熱部は、下流加熱部と、この下流加熱部よりも前記基材の流れ方向の上流側に位置する上流加熱部とを有し、前記低熱伝導部は、前記下流加熱部と前記上流加熱部との間に配置されている。 In one example, the first mold is provided on each of a pair of rollers, the first transverse heat welding portion is formed between the pair of rollers, and the first die is the first transverse heat welding portion. A heating part for forming the substrate, and a low thermal conductivity part made of a material having a lower thermal conductivity than the heating part and pressurizing the base material, wherein the heating part and the low thermal conduction part are the hollow The part is arranged so as to be divided into an upstream side and a downstream side in the flow direction of the base material, and the heating unit is located upstream of the downstream heating unit and the downstream heating unit in the flow direction of the base material An upstream heating section, and the low heat conduction section is disposed between the downstream heating section and the upstream heating section.
　上記方法では、第１金型において、下流加熱部と上流加熱部との間には、加熱部よりも熱伝導性の低い材料から構成され、基材を加圧する低熱伝導部が配置されている。このため、第１金型を用いる第１サブ段階では、一対のローラー間を通過する基材に対して、下流加熱部による下流熱溶着部の形成、低熱伝導部による加圧、上流加熱部による上流熱溶着部の形成がこの順で行われる。このため、下流熱溶着部と上流熱溶着部との間に位置する中空部分への内容物や気体の流入が抑制されるとともに、下流熱溶着部と上流熱溶着部との間に位置する基材の熱溶着が抑制される。従って、下流熱溶着部と上流熱溶着部との間に位置する基材は、第２金型を用いた第２サブ段階において流入部を形成する部分として好適に確保される。 In the above-described method, in the first mold, a low heat conductive portion that is made of a material having lower thermal conductivity than the heating portion and pressurizes the base material is disposed between the downstream heating portion and the upstream heating portion. . For this reason, in the first sub-stage using the first mold, for the base material passing between the pair of rollers, formation of the downstream heat welding portion by the downstream heating portion, pressurization by the low heat conduction portion, and by the upstream heating portion The upstream heat welding part is formed in this order. For this reason, inflow of the contents and gas into the hollow portion located between the downstream heat weld portion and the upstream heat weld portion is suppressed, and the base located between the downstream heat weld portion and the upstream heat weld portion. The thermal welding of the material is suppressed. Therefore, the base material located between the downstream heat welding part and the upstream heat welding part is suitably ensured as a part that forms the inflow part in the second sub-stage using the second mold.
　一例では、前記第２金型は、一対のローラーにそれぞれ設けられ、前記第２横熱溶着部は、前記一対のローラー間で形成され、前記第２金型は、前記第２横熱溶着部を形成するための加熱部と、前記加熱部よりも熱伝導性の低い材料から構成された低熱伝導部とを有し、前記低熱伝導部は、前記基材の流れ方向において前記第１横熱溶着部から上流側へ向かって前記基材を加圧する。 In one example, the second mold is provided on each of the pair of rollers, the second lateral heat welding part is formed between the pair of rollers, and the second mold is the second lateral heat welding part. And a low thermal conductivity portion made of a material having a lower thermal conductivity than the heating portion, and the low thermal conductivity portion is the first lateral heat in the flow direction of the base material. The substrate is pressurized from the welded portion toward the upstream side.
　上記方法では、第２サブ段階で用いる第２金型は、加熱部よりも熱伝導性の低い材料から構成された低熱伝導部を有している。低熱伝導部は、基材の流れ方向において第１横熱溶着部から上流側へ向かって前記基材を加圧する。このように低熱伝導部により加圧された部分では、内容物や気体の流入及び熱溶着が抑制される。 In the above method, the second mold used in the second sub-stage has a low heat conduction part made of a material having a lower thermal conductivity than the heating part. The low heat conduction part pressurizes the base material from the first lateral heat welding part toward the upstream side in the flow direction of the base material. Thus, in the part pressurized by the low heat conduction part, inflow of contents and gas and heat welding are suppressed.
　本発明の更に別の側面に従う包装物品連結体の製造方法は、縦方向に連続した中空部分を有する基材に横熱溶着部を形成する横熱溶着工程を備え、前記横熱溶着工程は、前記基材に、第１金型を用いて前記主熱溶着部が形成される条件で第１横熱溶着部を形成する第１サブ段階と、前記第１横熱溶着部を有する前記基材に、第２金型を用いて前記副熱溶着部が形成される条件で第２横熱溶着部を形成する第２サブ段階とを有する。 A manufacturing method of a packaged article assembly according to still another aspect of the present invention includes a transverse heat welding step of forming a transverse heat welding portion on a substrate having a hollow portion continuous in the vertical direction, and the transverse heat welding step includes: A first sub-stage for forming a first lateral heat welded portion on the base material under the condition that the main heat welded portion is formed using a first mold, and the base material having the first lateral heat welded portion. And a second sub-stage for forming the second transverse heat welded part on the condition that the secondary heat welded part is formed using a second mold.
　この方法によれば、主熱溶着部と副熱溶着部を形成する横熱溶着工程は、第１金型を用いる第１サブ段階及び第２金型を用いる第２サブ段階を有するため、第１サブ段階の条件と第２サブ段階の条件とを別々に設定することができる。このため、副熱溶着部と主熱溶着部のいずれも形成する横熱溶着工程において、熱溶着の条件設定が容易となる。 According to this method, the transverse heat welding process for forming the main heat welding portion and the sub heat welding portion includes the first sub-stage using the first mold and the second sub-stage using the second mold. The conditions for the first sub-stage and the conditions for the second sub-stage can be set separately. For this reason, in the transverse heat welding process in which both the auxiliary heat welding part and the main heat welding part are formed, it is easy to set conditions for heat welding.
　一例では、前記第２金型は、一対のローラーにそれぞれ設けられ、前記第２横熱溶着部は、前記一対のローラー間で形成され、前記第２金型は、前記第２横熱溶着部を形成するための加熱部と、前記加熱部よりも前記基材の流れ方向の下流側に位置するとともに前記加熱部よりも熱伝導性の低い材料から構成された低熱伝導部とを有し、前記低熱伝導部は、前記基材の流れ方向において前記第１横熱溶着部から上流側へ向かって前記基材を加圧する。 In one example, the second mold is provided on each of the pair of rollers, the second lateral heat welding part is formed between the pair of rollers, and the second mold is the second lateral heat welding part. A heating part for forming a low heat conduction part that is located downstream of the heating part in the flow direction of the base material and is made of a material having a lower thermal conductivity than the heating part, The low heat conduction part pressurizes the base material from the first lateral heat welding part toward the upstream side in the flow direction of the base material.
　この方法で用いられる第２金型は、加熱部よりも基材の流れ方向の下流側に位置するとともに加熱部よりも熱伝導性の低い材料から構成された低熱伝導部を有している。
　このため、第２金型を用いる第２サブ段階では、一対のローラー間を通過する基材に対して、低熱伝導部による加圧、加熱部による第２横熱溶着部の形成がこの順で行われる。このため、第１横熱溶着部と第２横熱溶着部との間に位置する基材の熱溶着が抑制される。従って、第１横熱溶着部と第２横熱溶着部との間に位置する基材は、第２金型を用いた第２サブ段階において流入部を形成する部分として好適に確保される。 The second mold used in this method has a low heat conduction part which is located downstream of the heating part in the flow direction of the base material and is made of a material having a lower thermal conductivity than the heating part.
For this reason, in the second sub-stage using the second mold, pressurization by the low heat conduction part and formation of the second transverse heat welding part by the heating part are performed in this order on the base material passing between the pair of rollers. Done. For this reason, the heat welding of the base material located between a 1st side heat weld part and a 2nd side heat weld part is suppressed. Therefore, the base material located between the first lateral heat welded portion and the second lateral heat welded portion is suitably secured as a portion that forms the inflow portion in the second sub-stage using the second mold.
　一例では、前記第１金型は、一対のローラーにそれぞれ設けられ、前記第１横熱溶着部は、前記一対のローラー間で形成され、前記第１金型は、前記第１横熱溶着部を形成するための加熱部と、前記加熱部よりも熱伝導性の低い材料から構成された低熱伝導部とを有し、前記低熱伝導部は、前記基材の流れ方向において前記第１横熱溶着部から上流側へ向かって前記基材を加圧する。 In one example, the first mold is provided on each of a pair of rollers, the first transverse heat welding portion is formed between the pair of rollers, and the first die is the first transverse heat welding portion. And a low thermal conductivity portion made of a material having a lower thermal conductivity than the heating portion, and the low thermal conductivity portion is the first lateral heat in the flow direction of the base material. The substrate is pressurized from the welded portion toward the upstream side.
　この方法で用いられる第１金型は、加熱部よりも熱伝導性の低い材料から構成された低熱伝導部を有し、低熱伝導部は、基材の流れ方向において第１横熱溶着部から上流側へ向かって前記基材を加圧するように構成されている。 The first mold used in this method has a low heat conduction part made of a material having lower heat conductivity than the heating part, and the low heat conduction part is formed from the first lateral heat weld part in the flow direction of the base material. It is comprised so that the said base material may be pressurized toward an upstream.
　このため、第１金型を用いる第１サブ段階では、一対のローラー間を通過する基材に対して、加熱部による第１横熱溶着部の形成、低熱伝導部による加圧がこの順で行われる。こうした低熱伝導部により加圧により、基材を一時的に密着させることが可能である。このように低熱伝導部により加圧された加圧部では、内容物や気体の流入が一時的に抑制される。 For this reason, in the first sub-stage using the first mold, the formation of the first transverse heat welded portion by the heating portion and the pressurization by the low heat conducting portion are performed in this order on the base material passing between the pair of rollers. Done. The substrate can be temporarily brought into close contact with such a low heat conduction portion by pressurization. Thus, in the pressurization part pressurized by the low heat conduction part, inflow of contents and gas is temporarily suppressed.

Examples of the contents 15 accommodated in the accommodating portion include food and drink. The form of the content 15 is not specifically limited, For example, liquid bodies, such as a liquid, a gel, and a paste, are mentioned. The content 15 may be a mixture of two or more different forms.
　本実施形態の各包装物品は、内容物１５として食品が収容されることが好ましく、より好ましくは液体調味料やからし等の調味料が収容される。調味料を収容した包装物品は、比較的小さい包装袋１４を備えており、包装袋１４の外形寸法のうち、最大となる外形寸法については、例えば１５０ｍｍ以下に構成されることが多い。 Each packaged article according to the present embodiment preferably contains food as the contents 15, and more preferably contains a seasoning such as a liquid seasoning or mustard.

Good.
　次に、包装物品連結体１１の作用について説明する。
　包装物品連結体１１の包装袋１４は、副熱溶着部２２の開封時に内容物１５が収容部から流入する流入部２３を有している。第１包装物品１２と第２包装物品１３とは、第２包装物品１３の流入部２３の下流端３３が、第１包装物品１２の主熱溶着部２１により封止された構造で連結されている。このため、第２包装物品１３の副熱溶着部２２が開封されることで流入部２３に内容物１５が流入したとしても、その内容物１５の外部への流出は第１包装物品１２の主熱溶着部２１により抑制される。 Next, the operation of the packaged article assembly 11 will be described.
The packaging bag 14 of the packaged article assembly 11 has an inflow portion 23 into which the content 15 flows from the storage portion when the auxiliary heat welding portion 22 is opened. The first packaging article 12 and the second packaging article 13 are connected by a structure in which the downstream end 33 of the inflow portion 23 of the second packaging article 13 is sealed by the main heat welding portion 21 of the first packaging article 12. Yes. For this reason, even if the contents 15 flow into the inflow portion 23 by opening the auxiliary heat welding portion 22 of the second packaging article 13, the outflow of the contents 15 to the outside of the first packaging article 12 is the main. It is suppressed by the heat welding part 21.
　包装物品連結体１１は、各包装物品に分離され、さらに包装体に収容されることが好ましい。例えば、内容物１５が調味料の場合、納豆等の食品とともに包装体に収容される。このように包装体に収容された包装物品は、包装体で保護されるため、収容部に過剰な力が加わることが低減される。包装物品の使用時には、収容部内の内圧を利用して副熱溶着部２２を開封する。例えば、手指等で収容部を押圧することで、副熱溶着部２２を開封することができる。 The packaged article connector 11 is preferably separated into each packaged article and further accommodated in the package. For example, when the content 15 is a seasoning, it is accommodated in a package together with food such as natto. Thus, since the packaging article accommodated in the packaging body is protected by the packaging body, an excessive force applied to the accommodation portion is reduced. When the packaged article is used, the auxiliary heat welding part 22 is opened using the internal pressure in the housing part. For example, the auxiliary heat welding part 22 can be opened by pressing a storage part with fingers or the like.
　＜包装物品連結体１１の製造方法＞
　次に、包装物品連結体１１の製造方法について説明する。
　図２（ａ）に示すように、包装物品連結体１１の製造方法は、縦方向に連続した中空部分を有する基材に、横熱溶着部を形成する横熱溶着工程Ｓｈを備えている。本実施形態では、横熱溶着工程Ｓｈの前に、基材に縦熱溶着部を形成し、中空部分を有する基材を得る縦熱溶着工程Ｓｖが行われる。縦熱溶着工程Ｓｖに供給される基材は、流れ方向Ｄに沿った折り部２４で二つ折りの状態とされている。縦熱溶着工程Ｓｖでは、折り部２４と反対側の側部が熱溶着されることで、縦熱溶着部が形成される。この縦熱溶着工程Ｓｖにより、基材は筒状に成形される。 <Method for producing packaged article assembly 11>

As shown to Fig.2 (a), the manufacturing method of the package article coupling body 11 is equipped with the transverse heat welding process Sh which forms a transverse heat welding part in the base material which has the hollow part continuous in the vertical direction. In the present embodiment, before the transverse heat welding step Sh, a longitudinal heat welding step Sv is performed in which a longitudinal heat welding portion is formed on the base material to obtain a base material having a hollow portion. The base material supplied to the longitudinal heat welding step Sv is folded in two at the folding portion 24 along the flow direction D. In the longitudinal heat welding step Sv, the longitudinal heat welded portion is formed by thermally welding the side portion opposite to the folded portion 24. By this longitudinal heat welding step Sv, the base material is formed into a cylindrical shape.
　縦熱溶着工程Ｓｖで得られた基材の中空部分には、ノズルＮから内容物１５が連続して注入される。本実施形態の内容物１５は、液状の調味料であるが、これに限定されない。第１実施形態の製造方法は、所謂液中シールが可能である液状体を内容物１５として収容する際に好適である。液中シールとは、中空部分に液状体が存在している基材に熱溶着部を形成する方法である。 The contents 15 are continuously injected from the nozzle N into the hollow portion of the base material obtained in the longitudinal heat welding step Sv. Although the content 15 of this embodiment is a liquid seasoning, it is not limited to this. The manufacturing method of the first embodiment is suitable when a liquid material capable of so-called submerged sealing is accommodated as the contents 15.

The pressure of the first sub-stage S1 (the pressure of the first mold) is, for example, in the range of 100 kPa or more and 500 kPa or less. The temperature of the second sub-stage S2 (the temperature of the second mold) is, for example, in the range of 100 ° C. or higher and 180 ° C. or lower. The pressure in the second sub-stage S2 (second mold pressure) is, for example, in the range of 100 kPa or more and 500 kPa or less.

As shown to Fig.2 (a), the manufacturing method of the package article coupling body 11 is equipped with the transverse heat welding process Sh which forms a transverse heat welding part in a base material. The transverse heat welding step Sh has a first sub-step S1 and a second sub-step S2. The first sub-step S1 is a step of forming the first lateral heat-welded portion 51 on the base material on the condition that the sub-heat-welded portion 22 is formed using the first mold 71. The second sub-step S2 is a step of forming the second lateral heat welded portion 52 on the base material having the first lateral heat welded portion 51 on the condition that the main heat welded portion 21 is formed using the second mold 81. It is.
　このように副熱溶着部２２と主熱溶着部２１を形成する横熱溶着工程Ｓｈは、第１金型７１を用いる第１サブ段階Ｓ１及び第２金型８１を用いる第２サブ段階Ｓ２を有するため、第１サブ段階Ｓ１の条件と第２サブ段階Ｓ２の条件とを別々に設定することができる。このため、副熱溶着部２２と主熱溶着部２１のいずれも形成する横熱溶着工程Ｓｈにおいて、熱溶着の条件設定が容易となる。 In this way, the lateral heat welding step Sh for forming the sub heat welding portion 22 and the main heat welding portion 21 includes the first sub step S1 using the first mold 71 and the second sub step S2 using the second die 81. Therefore, the conditions of the first sub-stage S1 and the conditions of the second sub-stage S2 can be set separately. For this reason, in the transverse heat welding process Sh in which both the auxiliary heat welding part 22 and the main heat welding part 21 are formed, it is easy to set conditions for the heat welding.
　図３（ａ）に示すように、第１金型７１を用いる第１サブ段階Ｓ１では、一対の第１ローラーＲ１間を通過する基材に対して、まず下流加熱部７２ａによる下流熱溶着部５１ａの形成及び第１低熱伝導部７３による加圧がこの順で行われる。 As shown in FIG. 3 (a), in the first sub-stage S1 using the first mold 71, the downstream heat welding portion by the downstream heating portion 72a is first applied to the base material passing between the pair of first rollers R1. Formation of 51a and pressurization by the first low heat conduction part 73 are performed in this order.
　図３（ｂ）に示すように、さらに基材には、第１低熱伝導部７３による加圧に続いて上流加熱部７２ｂによる上流熱溶着部５１ｂの形成が行われる。
　このような下流熱溶着部５１ａ及び上流熱溶着部５１ｂの形成に際して、下流熱溶着部５１ａと上流熱溶着部５１ｂとの間に位置する中空部分は、第１低熱伝導部７３により加圧されている。このため、下流熱溶着部５１ａと上流熱溶着部５１ｂとの間に位置する中空部分への内容物１５や気体の流入が抑制されるとともに、下流熱溶着部５１ａと上流熱溶着部５１ｂとの間に位置する基材の熱溶着が抑制される。従って、下流熱溶着部５１ａと上流熱溶着部５１ｂとの間に位置する基材は、第２金型８１を用いた第２サブ段階Ｓ２において流入部２３を形成する部分として好適に確保される。 As shown in FIG. 3 (b), the upstream heat welding part 51 b is formed by the upstream heating part 72 b following the pressurization by the first low heat conduction part 73 on the base material.
When forming the downstream heat welding portion 51a and the upstream heat welding portion 51b, the hollow portion located between the downstream heat welding portion 51a and the upstream heat welding portion 51b is pressurized by the first low heat conduction portion 73. Yes. For this reason, while the inflow of the content 15 and gas to the hollow part located between the downstream heat welding part 51a and the upstream heat welding part 51b is suppressed, between the downstream heat welding part 51a and the upstream heat welding part 51b, The thermal welding of the base material located between is suppressed. Therefore, the base material located between the downstream heat welding part 51a and the upstream heat welding part 51b is suitably secured as a part for forming the inflow part 23 in the second sub-stage S2 using the second mold 81. .
　図３（ｃ）に示すように、第２金型８１を用いる第２サブ段階Ｓ２では、一対の第２ローラーＲ２間を通過する基材に対して、第２横熱溶着部５２の形成が行われる。第２サブ段階Ｓ２は、第１サブ段階Ｓ１において第１加熱部７２及び第１低熱伝導部７３により加圧されていた位置に対応して行われる。 As shown in FIG.3 (c), in 2nd sub step S2 using the 2nd metal mold | die 81, formation of the 2nd side heat welding part 52 is performed with respect to the base material which passes between between a pair of 2nd rollers R2. Done. The second sub-step S2 is performed corresponding to the position where the pressure is applied by the first heating unit 72 and the first low heat conduction unit 73 in the first sub-step S1.
　図３（ｄ）に示すように、一対の第２ローラーＲ２間を基材が進行するに伴って、上述した流入部２３が形成されるとともに、上流熱溶着部５１ｂの一部は、包装物品の使用時に開封される副熱溶着部２２として残留される。 As shown in FIG. 3D, as the base material advances between the pair of second rollers R2, the inflow portion 23 described above is formed, and a part of the upstream heat weld portion 51b is a packaging article. It remains as the secondary heat welding part 22 opened at the time of use.
　第１実施形態によって発揮される効果について、以下に記載する。
　（１）包装物品連結体１１は、第２包装物品１３の流入部２３の下流端３３が、第１包装物品１２の主熱溶着部２１により封止された構造を有する。このため、第２包装物品１３の副熱溶着部２２が開封されることで流入部２３に内容物１５が流入したとしても、その内容物１５の外部への流出は第１包装物品１２の主熱溶着部２１により抑制される。従って、包装物品の内容物１５が漏れることを抑制することができる。 The effects exhibited by the first embodiment are described below.
(1) The packaged article connector 11 has a structure in which the downstream end 33 of the inflow part 23 of the second packaged article 13 is sealed by the main heat welding part 21 of the first packaged article 12. For this reason, even if the contents 15 flow into the inflow portion 23 by opening the auxiliary heat welding portion 22 of the second packaging article 13, the outflow of the contents 15 to the outside of the first packaging article 12 is the main. It is suppressed by the heat welding part 21. Therefore, it can suppress that the contents 15 of a packaging article leak.
　（２）包装物品連結体１１の製造方法は、基材に横熱溶着部を形成する横熱溶着工程Ｓｈを備えている。横熱溶着工程Ｓｈは、第１サブ段階Ｓ１と第２サブ段階Ｓ２とを有する。第１サブ段階Ｓ１は、基材に、第１金型７１を用いて副熱溶着部２２が形成される条件で第１横熱溶着部５１を形成する段階である。第２サブ段階Ｓ２は、第１横熱溶着部５１を有する基材に、第２金型８１を用いて主熱溶着部２１が形成される条件で第２横熱溶着部５２を形成する段階である。この方法によれば、副熱溶着部２２と主熱溶着部２１のいずれも形成する横熱溶着工程Ｓｈにおいて、熱溶着の条件設定が容易となる。従って、副熱溶着部２２を有する包装物品連結体１１を容易に製造することができる。 (2) The manufacturing method of the packaged article assembly 11 includes a transverse heat welding step Sh for forming a transverse heat welded portion on the base material. The transverse heat welding step Sh has a first sub-step S1 and a second sub-step S2. The first sub-step S1 is a step of forming the first lateral heat-welded portion 51 on the base material on the condition that the sub-heat-welded portion 22 is formed using the first mold 71. The second sub-step S2 is a step of forming the second lateral heat welded portion 52 on the base material having the first lateral heat welded portion 51 on the condition that the main heat welded portion 21 is formed using the second mold 81. It is. According to this method, in the transverse heat welding step Sh in which both the auxiliary heat welding part 22 and the main heat welding part 21 are formed, it is easy to set conditions for heat welding. Therefore, the packaged article assembly 11 having the auxiliary heat welding part 22 can be easily manufactured.
　（３）包装物品連結体１１の製造方法において、第１金型７１は、一対の第１ローラーＲ１にそれぞれ設けられ、第１横熱溶着部５１は、一対の第１ローラーＲ１間で形成される。第１金型７１は、第１横熱溶着部５１を形成するための第１加熱部７２と、第１加熱部７２よりも熱伝導性の低い材料から構成され、基材を加圧する第１低熱伝導部７３とを有している。第１加熱部７２及び第１低熱伝導部７３は、基材の中空部分を基材の流れ方向Ｄの上流側と下流側とに仕切るように配置されている。第１加熱部７２は、下流加熱部７２ａと基材の流れ方向Ｄにおいて上流側に位置する上流加熱部７２ｂとを有している。第１低熱伝導部７３は、下流加熱部７２ａと上流加熱部７２ｂとの間に配置されている。 (3) In the manufacturing method of the packaged article assembly 11, the first mold 71 is provided on each of the pair of first rollers R1, and the first transverse heat welding portion 51 is formed between the pair of first rollers R1. The The 1st metal mold | die 71 is comprised from the 1st heating part 72 for forming the 1st side heat welding part 51, and the material whose heat conductivity is lower than the 1st heating part 72, and pressurizes a base material. And a low heat conduction portion 73. The 1st heating part 72 and the 1st low heat conduction part 73 are arrange | positioned so that the hollow part of a base material may be divided into the upstream and downstream of the flow direction D of a base material. The 1st heating part 72 has the downstream heating part 72a and the upstream heating part 72b located in an upstream in the flow direction D of a base material. The first low heat conduction unit 73 is disposed between the downstream heating unit 72a and the upstream heating unit 72b.
　この方法によれば、下流熱溶着部５１ａと上流熱溶着部５１ｂとの間に位置する中空部分への内容物１５や気体の流入が抑制されるとともに、下流熱溶着部５１ａと上流熱溶着部５１ｂとの間に位置する基材の熱溶着が抑制される。従って、下流熱溶着部５１ａと上流熱溶着部５１ｂとの間に位置する基材は、第２金型８１を用いた第２サブ段階Ｓ２において流入部２３を形成する部分として好適に確保される。これにより、流入部２３への内容物１５や気体の流入を抑制することが容易となり、かつ流入部２３の形状や物性を安定して製造することが容易となる。 According to this method, the inflow of the contents 15 and the gas into the hollow portion located between the downstream heat weld portion 51a and the upstream heat weld portion 51b is suppressed, and the downstream heat weld portion 51a and the upstream heat weld portion. The thermal welding of the base material located between 51b is suppressed. Therefore, the base material located between the downstream heat welding part 51a and the upstream heat welding part 51b is suitably secured as a part for forming the inflow part 23 in the second sub-stage S2 using the second mold 81. . Thereby, it becomes easy to suppress the inflow of the contents 15 and the gas into the inflow portion 23, and it becomes easy to stably manufacture the shape and physical properties of the inflow portion 23.
　（４）第１実施形態の製造方法では、下流熱溶着部５１ａと上流熱溶着部５１ｂとの間に位置する中空部分への内容物１５の流入が抑制される。このため、内容物１５として液状体を収容する包装物品連結体１１の製造方法において、液状体を間欠的に充填するのではなく、液状体を連続的に充填する液中シールが可能となる。液中シールでは、基材の搬送と液状体の充填とを連続的に行うことが可能であるため、包装物品連結体１１の生産速度について、従来の包装物品連続体と遜色なく確保できる。従って、本実施形態の製造方法は、経済面でも有利である。 (4) In the manufacturing method according to the first embodiment, the inflow of the content 15 into the hollow portion located between the downstream heat welding portion 51a and the upstream heat welding portion 51b is suppressed. For this reason, in the manufacturing method of the package article coupling body 11 that contains the liquid material as the contents 15, it is possible to perform submerged sealing in which the liquid material is continuously filled instead of intermittently filling the liquid material. In the submerged seal, the conveyance of the base material and the filling of the liquid material can be performed continuously, so that the production speed of the packaged article linking body 11 can be ensured comparable to the conventional packaged article continuum. Therefore, the manufacturing method of the present embodiment is also advantageous from the economical aspect.

The transverse heat welding process Sh includes a first sub-stage S1c and a second sub-stage S2c. The first sub-stage S1c is a stage in which the first lateral heat welded portion 61 is formed on the base material on the condition that the main heat welded portion 21 is formed using the first mold 91. The second sub-step S2c is a step of forming the second lateral heat weld portion 62 on the base material having the first lateral heat weld portion 51 on the condition that the secondary heat weld portion 22 is formed using the second mold 101. It is. According to this method, in the transverse heat welding step Sh in which both the main heat welding part 21 and the sub heat welding part 22 are formed, it is easy to set the heat welding conditions. Therefore, the packaged article assembly 11 having the auxiliary heat welding part 22 can be easily manufactured.
　（８）包装物品連結体１１の製造方法において、第２金型１０１は、一対の第２ローラーＲ２にそれぞれ設けられ、第２横熱溶着部６２は、一対の第２ローラーＲ２間で形成される。第２金型１０１は、第２横熱溶着部６２を形成するための第２加熱部１０２と、第２加熱部１０２よりも基材の流れ方向Ｄの下流側に位置するとともに第２加熱部１０２よりも熱伝導性の低い材料から構成された第２低熱伝導部１０３とを有している。第２低熱伝導部１０３は、基材の流れ方向Ｄにおいて第１横熱溶着部６１から上流側へ向かって基材を加圧するように構成されている。この方法によれば、第２金型１０１を用いる第２サブ段階Ｓ２ｃでは、一対の第２ローラーＲ２間を通過する基材に対して、第２低熱伝導部１０３による加圧、第２加熱部１０２による第２横熱溶着部６２の形成がこの順で行われる。このため、第１横熱溶着部６１と第２横熱溶着部６２との間に位置する基材の熱溶着が抑制される。従って、第１横熱溶着部６１と第２横熱溶着部６２との間に位置する基材は、第２金型１０１を用いた第２サブ段階Ｓ２ｃにおいて流入部２３を形成する部分として好適に確保される。これにより、流入部２３への内容物１５や気体の流入を抑制することが容易となり、かつ流入部２３の形状や物性を安定して製造することが容易となる。 (8) In the manufacturing method of the packaged article assembly 11, the second mold 101 is provided on each of the pair of second rollers R2, and the second transverse heat welding portion 62 is formed between the pair of second rollers R2. The The second mold 101 is located on the downstream side in the base material flow direction D with respect to the second heating unit 102 for forming the second transverse heat welding unit 62, and the second heating unit 102. And a second low thermal conductive portion 103 made of a material having a lower thermal conductivity than 102. The second low heat conduction part 103 is configured to pressurize the base material from the first lateral heat welding part 61 toward the upstream side in the base material flow direction D. According to this method, in the second sub-step S2c using the second mold 101, the second low heat conduction unit 103 is pressed against the base material passing between the pair of second rollers R2, the second heating unit. The formation of the second transverse heat welded portion 62 by 102 is performed in this order. For this reason, the heat welding of the base material located between the 1st side heat weld part 61 and the 2nd side heat weld part 62 is suppressed. Therefore, the base material positioned between the first lateral heat weld portion 61 and the second lateral heat weld portion 62 is suitable as a portion for forming the inflow portion 23 in the second sub-stage S2c using the second mold 101. Secured. Thereby, it becomes easy to suppress the inflow of the contents 15 and the gas into the inflow portion 23, and it becomes easy to stably manufacture the shape and physical properties of the inflow portion 23.
　（９）第４実施形態の製造方法では、第１横熱溶着部６１と第２横熱溶着部６２との間に位置する中空部分への内容物１５の流入が抑制される。このため、内容物１５として液状体を収容する包装物品連結体１１の製造方法において、液状体を間欠的に充填するのではなく、液状体を連続的に充填する液中シールが可能となる。液中シールでは、基材の搬送と液状体の充填とを連続的に行うことが可能であるため、包装物品連結体１１の生産速度について、従来の包装物品連続体と遜色なく確保できる。従って、本実施形態の製造方法は、経済面でも有利である。 (9) In the manufacturing method of the fourth embodiment, the inflow of the content 15 into the hollow portion located between the first lateral heat weld portion 61 and the second lateral heat weld portion 62 is suppressed. For this reason, in the manufacturing method of the package article coupling body 11 that contains the liquid material as the contents 15, it is possible to perform submerged sealing in which the liquid material is continuously filled instead of intermittently filling the liquid material. In the submerged seal, the conveyance of the base material and the filling of the liquid material can be performed continuously, so that the production speed of the packaged article linking body 11 can be ensured comparable to the conventional packaged article continuum. Therefore, the manufacturing method of the present embodiment is also advantageous from the economical aspect.
　（１０）上記第１実施形態（図２）に示される製造方法では、横熱溶着工程Ｓｈにおける第１サブ段階Ｓ１後、下流熱溶着部５１ａ又は上流熱溶着部５１ｂの熱溶着強度が不足すると、下流熱溶着部５１ａと上流熱溶着部５１ｂとの間に内容物１５や気体の流入を許容する場合がある。このような内容物１５や気体の流入をさらに抑制する場合、第１サブ段階Ｓ１ｃにおける副熱溶着部２２の熱溶着強度を高める必要があり、副熱溶着部２２の熱溶着強度についての設定の自由度が低下することになる。この点、第４実施形態の製造方法では、第１サブ段階Ｓ１ｃにより主熱溶着部２１を形成するとともに第２サブ段階Ｓ２ｃで副熱溶着部２２を形成している。このため、副熱溶着部２２の熱溶着強度については、第２サブ段階Ｓ２ｃ以降で必要とされる強度に設定することができる。従って、副熱溶着部２２の熱溶着強度の設定について自由度を増すことが可能である。これにより、収容部内の内圧を利用して副熱溶着部２２を開封する包装物品においては、副熱溶着部２２を利用してさらに容易に開封できるように構成することが可能となる。 (10) In the manufacturing method shown in the first embodiment (FIG. 2), if the thermal welding strength of the downstream thermal welding part 51a or the upstream thermal welding part 51b is insufficient after the first sub-stage S1 in the lateral thermal welding process Sh. In some cases, the inflow of the contents 15 or gas may be allowed between the downstream heat welding portion 51a and the upstream heat welding portion 51b. In order to further suppress the inflow of such contents 15 and gas, it is necessary to increase the thermal welding strength of the auxiliary heat welding portion 22 in the first sub-stage S1c, and the setting of the thermal welding strength of the auxiliary heat welding portion 22 is set. The degree of freedom will be reduced. In this regard, in the manufacturing method of the fourth embodiment, the main heat welded portion 21 is formed in the first sub-stage S1c and the sub-heat welded portion 22 is formed in the second sub-stage S2c. For this reason, about the heat welding intensity | strength of the auxiliary | assistant heat welding part 22, it can be set to the intensity | strength required after 2nd sub step S2c. Therefore, it is possible to increase the degree of freedom for setting the heat welding strength of the auxiliary heat welding part 22. Thereby, in the packaging article which opens the sub heat welding part 22 using the internal pressure in an accommodating part, it becomes possible to comprise so that it can open more easily using the sub heat welding part 22. FIG.

Further, in the second sub-stage S2d in the transverse heat welding step Sh of the fifth embodiment, the second transverse heat welded portion 62 is formed under the condition that the subheat welded portion 22 is formed.
　図７（ｂ）に示すように、第５実施形態の第１金型９１における第１加熱部９２は、第１実施形態で用いた第２金型８１の第２加熱部８２と同様に形状を有している。第５実施形態で用いる第１金型９１の基材を加圧する面は、第１横熱溶着部６１を形成するための第１加熱部９２と、第１加熱部９２よりも熱伝導性の低い材料から構成される第１低熱伝導部９３とを有している。第１加熱部９２は、基材の中空部分を横方向に沿って封止する長さに延在している。第１低熱伝導部９３は、第１実施形態の第１低熱伝導部７３と同様の材料から構成される。第１低熱伝導部９３は、第１横熱溶着部６１から上流側へ向かって加圧する。 As shown in FIG. 7B, the first heating unit 92 in the first mold 91 of the fifth embodiment has the same shape as the second heating unit 82 of the second mold 81 used in the first embodiment. have. The surface of the first mold 91 used in the fifth embodiment that pressurizes the base material has a first heating unit 92 for forming the first lateral heat welding unit 61 and a thermal conductivity than the first heating unit 92. It has the 1st low heat conduction part 93 comprised from a low material. The 1st heating part 92 is extended in the length which seals the hollow part of a base material along a horizontal direction. The first low heat conduction unit 93 is made of the same material as the first low heat conduction unit 73 of the first embodiment. The first low heat conduction part 93 pressurizes from the first lateral heat welding part 61 toward the upstream side.
　図７（ｃ）に示すように、第２金型１０１の第２加熱部１０２は、第２横熱溶着部６２を形成するように構成されている。

The effects exhibited by the fifth embodiment will be described below.
　第１サブ段階Ｓ１ｄで用いる第１金型９１は、第１加熱部９２よりも熱伝導性の低い材料から構成された第１低熱伝導部９３を有している。第１低熱伝導部９３は、基材の流れ方向Ｄにおいて第１横熱溶着部６１から上流側へ向かって基材を加圧するように構成されている。 The first mold 91 used in the first sub-stage S1d has a first low heat conduction part 93 made of a material having lower heat conductivity than the first heating part 92. The first low heat conduction portion 93 is configured to pressurize the base material from the first lateral heat weld portion 61 toward the upstream side in the flow direction D of the base material.
　こうした第１サブ段階Ｓ１ｄでは、一対の第１ローラーＲ１間を通過する基材に対して、第１加熱部９２による第１横熱溶着部６１の形成、第１低熱伝導部９３による加圧がこの順で行われる。こうした第１低熱伝導部９３により加圧により、基材を一時的に密着させることが可能である。このように第１低熱伝導部９３により加圧された加圧部６３では、内容物１５や気体の流入が一時的に抑制される。 In such a first sub-stage S1d, formation of the first transverse heat welded portion 61 by the first heating unit 92 and pressurization by the first low heat conducting unit 93 are performed on the base material passing between the pair of first rollers R1. This is done in this order. The base material can be temporarily brought into close contact with the first low heat conduction portion 93 by pressurization. Thus, in the pressurization part 63 pressurized by the 1st low heat conduction part 93, inflow of the contents 15 and gas is suppressed temporarily.
　（１１）包装物品連結体１１の製造方法において、第１金型９１は、一対の第１ローラーＲ１にそれぞれ設けられている。第１横熱溶着部６１は、一対の第１ローラーＲ１間で形成される。第１金型９１は、第１横熱溶着部６１を形成するための第１加熱部９２と、第１加熱部９２よりも熱伝導性の低い材料から構成される第１低熱伝導部９３とを有している。第１低熱伝導部９３は、第１横熱溶着部６１の下流側を加圧する。 (11) In the method for manufacturing the packaged article assembly 11, the first mold 91 is provided on each of the pair of first rollers R1. The 1st side heat welding part 61 is formed between a pair of 1st roller R1. The first mold 91 includes a first heating unit 92 for forming the first lateral heat welding unit 61, a first low thermal conduction unit 93 made of a material having lower thermal conductivity than the first heating unit 92, and have. The first low heat conducting portion 93 pressurizes the downstream side of the first lateral heat welding portion 61.

　（変更例）
　各実施形態を次のように変更することもできる。
　・各実施形態の包装物品連結体１１において、包装袋１４の第１側縁３１は、主熱溶着部２１により形成されているが、包装袋１４の折り部２４により形成されていてもよい。また、各実施形態の包装物品連結体１１において、包装袋１４の第２側縁３２は、主熱溶着部２１である横熱溶着部により形成されているが、同じく主熱溶着部２１である縦熱溶着部により形成されていてもよい。こうした変更例の包装物品連結体１１についても、前記各実施形態の製造方法を適用されてもよい。 (Example of change)
Each embodiment may be modified as follows.
In the package article linking body 11 of each embodiment, the first side edge 31 of the packaging bag 14 is formed by the main heat welding portion 21, but may be formed by the folding portion 24 of the packaging bag 14. Moreover, in the package article coupling body 11 of each embodiment, the second side edge 32 of the packaging bag 14 is formed by the transverse heat welded portion that is the main heat welded portion 21, but is also the main heat welded portion 21. It may be formed by the longitudinal heat welding part. The manufacturing method of each of the above embodiments may also be applied to the packaged article assembly 11 of such a modified example.
　・各実施形態の包装物品連結体１１において、包装袋１４は三方シール構造を有しているが、折り部２４が縦熱溶着部から構成されている四方シール構造の包装袋１４に変更されてもよい。さらに、包装袋１４は、縦ピロー包装袋に変更されてもよい。 In the package article linking body 11 of each embodiment, the packaging bag 14 has a three-side seal structure, but the folding portion 24 is changed to a packaging bag 14 having a four-side seal structure in which a longitudinal heat welding portion is configured. Also good. Furthermore, the packaging bag 14 may be changed to a vertical pillow packaging bag.
　・各実施形態の製造方法では、縦熱溶着工程Ｓｖを有しているが、横熱溶着工程Ｓｈのみを有する製造方法に変更されてもよい。すなわち、各実施形態の製造方法は、中空部分を有する基材を予め準備し、その基材を用いた包装物品連結体１１の製造方法に変更することができる。但し、この場合、連結される包装物品の数を増加させることや内容物１５の注入が困難である。この点、各実施形態のように縦熱溶着工程Ｓｖを有する製造方法は、生産性を高めることが容易となるため、有利である。 -In the manufacturing method of each embodiment, although it has the longitudinal heat welding process Sv, you may change into the manufacturing method which has only a transverse heat welding process Sh. That is, the manufacturing method of each embodiment can prepare the base material which has a hollow part beforehand, and can change into the manufacturing method of the packaged article coupling body 11 using the base material. However, in this case, it is difficult to increase the number of connected packaging articles and to inject the contents 15. In this respect, the manufacturing method having the longitudinal heat welding step Sv as in each embodiment is advantageous because it becomes easy to increase productivity.
　・第１実施形態の製造方法で用いる第１金型７１の第１加熱部７２は、基材の流れ方向Ｄの上流側と下流側とを仕切らずに下流加熱部７２ａと上流加熱部７２ｂとを連結する中間加熱部をさらに有していてもよい。すなわち、第１加熱部７２は、下流加熱部７２ａ及び上流加熱部７２ｂに加えて中間加熱部を有する形状（枠状やコ字状）に変更されてもよい。また、第１加熱部７２は、例えば、下流加熱部７２ａの一端と上流加熱部７２ｂの一端とが連結された形状に変更されてもよいし、下流加熱部７２ａの一端と上流加熱部７２ｂの一端が連結され、かつ下流加熱部７２ａの他端と上流加熱部７２ｂの他端が連結された形状に変更されてもよい。このように、下流加熱部７２ａと上流加熱部７２ｂとは、第１低熱伝導部７３が配置される部分が離間されていればよく、それ以外の部分は連結されていてもよい。 -The 1st heating part 72 of the 1st metal mold 71 used with the manufacturing method of a 1st embodiment does not partition the upstream and downstream of the flow direction D of a base material, and the downstream heating part 72a and the upstream heating part 72b, You may further have the intermediate heating part which connects. That is, the 1st heating part 72 may be changed into the shape (frame shape or U shape) which has an intermediate heating part in addition to the downstream heating part 72a and the upstream heating part 72b. Moreover, the 1st heating part 72 may be changed into the shape with which the end of the downstream heating part 72a and the end of the upstream heating part 72b were connected, for example, the end of the downstream heating part 72a, and the upstream heating part 72b The shape may be changed so that one end is connected and the other end of the downstream heating unit 72a and the other end of the upstream heating unit 72b are connected. Thus, the downstream heating unit 72a and the upstream heating unit 72b only need to be separated from each other at the portion where the first low heat conduction unit 73 is disposed, and other portions may be connected.
　・第１実施形態の製造方法で用いた第１金型７１は、第１低熱伝導部７３を有しているが、第１低熱伝導部７３を第１加熱部７２と同じ材料から形成した第１金型に変更されてもよい。この第１金型の場合、下流加熱部７２ａと上流加熱部７２ｂとの間は、下流加熱部７２ａ及び上流加熱部７２ｂよりも低温になるように温度制御される。これにより、下流熱溶着部５１ａと上流熱溶着部５１ｂとの間に位置する基材の熱溶着を抑制することも可能である。第２実施形態の製造方法で用いる第２金型８１、第４実施形態の製造方法で用いる第２金型１０１、及び第５実施形態の製造方法で用いる第１金型９１も同様に変更することができる。この変更例の場合では、第１金型又は第２金型の温度制御が煩雑になるおそれや所望の温度に設定することが困難になるおそれがある。この観点において、第１実施形態及び第２実施形態の製造方法が有利である。 -Although the 1st metal mold | die 71 used with the manufacturing method of 1st Embodiment has the 1st low heat conductive part 73, the 1st low heat conductive part 73 was formed from the same material as the 1st heating part 72. It may be changed to one mold. In the case of this first mold, the temperature between the downstream heating unit 72a and the upstream heating unit 72b is controlled to be lower than that of the downstream heating unit 72a and the upstream heating unit 72b. Thereby, it is also possible to suppress the heat welding of the base material located between the downstream heat welding part 51a and the upstream heat welding part 51b. The second mold 81 used in the manufacturing method of the second embodiment, the second mold 101 used in the manufacturing method of the fourth embodiment, and the first mold 91 used in the manufacturing method of the fifth embodiment are similarly changed. be able to. In the case of this modified example, the temperature control of the first mold or the second mold may be complicated or it may be difficult to set the temperature to a desired temperature. In this respect, the manufacturing methods of the first embodiment and the second embodiment are advantageous.
　・第２実施形態において、第１金型７１の第１加熱部７２は、第１横熱溶着部５１が基材の中空部分を基材の流れ方向Ｄの上流側と下流側とに仕切るように配置されるように変更されてもよい。 -In 2nd Embodiment, the 1st heating part 72 of the 1st metal mold | die 71 is such that the 1st side heat welding part 51 partitions the hollow part of a base material into the upstream and downstream of the flow direction D of a base material. It may be changed so that it is arranged.
　・第４実施形態において、第２金型１０１の第２低熱伝導部１０３は省略されてもよい。第５実施形態においても、第１金型９１の第１低熱伝導部９３は省略されてもよい。このように第２低熱伝導部１０３及び第１低熱伝導部９３を省略した場合、基材の搬送及び包装袋１４への内容物１５の注入が断続的に行われる。すなわち、第１サブ段階及び第２サブ段階の完了後の横熱溶着部の上流側に内容物１５を注入する。その後、第１サブ段階を行うことにより第１横熱溶着部５１を形成する。続いて、内容物１５の注入を停止し、第２サブ段階を行うことで、横熱溶着部を形成する。 -In 4th Embodiment, the 2nd low heat conductive part 103 of the 2nd metal mold | die 101 may be abbreviate | omitted. Also in the fifth embodiment, the first low thermal conductive portion 93 of the first mold 91 may be omitted. Thus, when the 2nd low heat conductive part 103 and the 1st low heat conductive part 93 are abbreviate | omitted, conveyance of a base material and injection | pouring of the content 15 to the packaging bag 14 are performed intermittently. That is, the contents 15 are injected upstream of the transverse heat weld after completion of the first sub-stage and the second sub-stage. Then, the 1st side heat weld part 51 is formed by performing a 1st sub step. Subsequently, the injection of the contents 15 is stopped, and the second sub-stage is performed to form the transverse heat welded portion.
