Summary of the Invention

Problems to be Solved by the Invention

[0005] ​However, in conventional containers, even if the spout is placed inside the container and the entire container is sealed with barrier packaging to prevent oxygen from entering from the outside, there is a space where the spout outlet is located, separated from the area containing the contents, and oxygen remains in this space. Moreover, because the spout opening is sealed, the residual oxygen gradually permeates through the spout and enters the containment area, causing the contents inside to gradually oxidize. Therefore, when non-flowing contents are contained, there is a problem in that the contents, whose color and taste may change or whose components may change due to oxidation, remain stagnant near the spout without diffusing.

[0006] Therefore, the present invention provides a container that can prevent oxidation of the contents that remain near the spout. of The challenge is to provide it. [Means for solving the problem]

[0007] The present invention, which solves the above problems, is a container in which a substance that undergoes changes due to oxidation is contained inside a flexible packaging material having gas barrier properties, and a three-dimensional spout is arranged therein, wherein the substance is a liquid that becomes semi-solid after sealing, and the spout has through holes that are always open at both ends. This spout may be configured to be detachable.

[0008] According to the container of the present invention, a three-dimensional spout with both ends always open is housed and positioned inside the container. Therefore, when the container is sealed with contents inside, no space is formed inside the container that does not directly contact the contents. As a result, oxygen from this space does not gradually permeate through the spout into the container where the contents are stored.

[0009] When a substance that changes from liquid to semi-solid after being sealed is placed in this container, the substance remains fluid before it semi-solidifies. Therefore, even if the substance is oxidized by oxygen in the air remaining in the container, the oxygen diffuses into the substance. As a result, the oxygen in the air remaining in the container is already consumed, and oxygen does not gradually enter through the spout, preventing oxidation of the substance. Consequently, it is possible to prevent the accumulation of oxidized substance near the spout. Therefore, it is possible to provide a container that can prevent oxidation of the contents that remain near the spout.

[0010] In the container of the present invention, the spout may be configured to be separable, and packaging material may be continuously joined to the outer surface of each spout in the circumferential direction. By separating and removing the spout in this way, the shape and other characteristics can be altered, making it easier to achieve various shapes required during use and increasing design flexibility. Furthermore, even if the spout is designed to be separable, air does not remain between the separated spout and the packaging material, nor does any remaining air move between them. This prevents oxygen in the air from entering the containment and causing oxidation of the contents.

[0011] In the container of the present invention, the spout may have a spout body and a separator that is detachably attached to the spout body, and the packaging material may be detachable together with the separator. In this way, by separating and removing the spout separator, the packaging material can be removed together. Therefore, a two-step process of breaking the packaging material to open it and then separating the spout is unnecessary, and the packaging material can be broken and the spout separated in a single operation, making it easier to open the container.

[0012] In the container of the present invention, a holding portion for holding the contents may be provided protruding into the through-hole of the separator. In this way, when the separator is separated from the spout body during opening, it is possible to prevent any contents remaining in the packaging material attached to the separator or in the through-hole of the separator from leaking out through the through-hole of the separator after separation.

[0013] In the container of the present invention, the spout body may be provided with a connecting portion to other components, and the connecting portion may be covered in a liquid-tight manner by a separator. In this way, the contents of the container do not come into contact with the connecting part until it is used. Therefore, when in use, the contents are not attached to the connecting part, making it easier to connect other components to the connecting part, and it is also hygienic as the contents that have adhered to the connecting part will not further adhere to the surrounding area.

[0014] In the container of the present invention, it is preferable that the outer surface of the spout body and the outer surface of the separator are adjacent to each other. In particular, it is preferable that the joint portion with the packaging material on the outer surface of the spout body and the joint portion with the packaging material on the outer surface of the separator have the same outer surface shape. This method makes it easier to join the packaging material to both parts. Furthermore, after joining, no deformation occurs in the packaging material between the part joined to the spout body and the part joined to the separator, thus preventing joining defects such as cracks. In addition, gaps are less likely to form between the spout body, the separator, and the packaging material, making it less likely for air to remain in these areas.

[0015] The spout of the present invention is a spout that is joined to packaging material so as to be housed and arranged inside a container, and comprises a spout body located at one end and a separator located at the other end and detachably locked to the spout body, wherein the spout body and the separator are provided with through holes communicating with each other, and the outer circumferential surfaces of the spout body and the separator are provided with joining portions for packaging material having the same outer circumferential shape. With this type of spout, it is easy to manufacture a container that has the above-mentioned effects by joining it to the packaging material. [Effects of the Invention]

[0016] Container of the present invention toAccording to this, a container that can prevent the contents staying near the spout from being oxidized can be provided. of It is possible to provide.

Modes for Carrying Out the Invention

[0018] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1(a) and 1(b), the container 10 includes a flexible packaging material 11 having gas barrier properties and a three-dimensional spout 20 disposed in a state of being housed inside the packaging material 11. A peripheral seal 12 capable of sealing the inside is provided on the outer periphery of the packaging material 11. The spout 20 is continuously joined to the inner surface of the packaging material 11 from the peripheral seal portion 12. As a result, a storage portion 13 for storing the contents is formed on one side of the spout 20, and a small space 14 formed by housing the three-dimensional spout 20 is formed on the other side. The spout 20 is provided with a through hole 21 that is always open at both ends. One end of the through hole 21 communicates with the storage portion 13, and the other end communicates with the small space 14.

[0019] The packaging material 11 is made of a sheet of flexible resin and may be a laminated sheet with a gas barrier layer such as an aluminum vapor-deposited layer. The innermost layer is provided with a sealant layer made of resin that can stably contain the contents and to which the spout 20 can be welded.

[0020] As shown in Figures 2 to 4(a) and (b), the spout 20 of this embodiment has a spout body 22 positioned on one end side that faces the housing 13, and a separator 23 positioned on the other end side and detachably locked to the spout body 22.

[0021] The spout body 22 comprises a boat-shaped section 24a that is liquid-tightly joined to the packaging material 11, and a substantially cylindrical projection 25 that protrudes outward from the boat-shaped section 24a. The boat-shaped section 24a and the protruding section 25 are provided with through-holes 21a that are normally open at both ends. The through-holes 21a have a hollow section 26a that opens towards the housing section 13 and a circular hole section 26b that has a smaller cross-sectional area than the hollow section 26a.

[0022] A joint portion 27a for connecting with the packaging material 11 is provided on the outer circumferential surface of the boat-shaped 24a. The joint portion 27a is provided in a boat shape so as to be continuous around the entire circumference of the boat-shaped 24a. A connecting portion 28 for connecting to other members is provided on the outer circumferential surface of the protruding portion 25. In this embodiment, a locking structure for securing a tube when in use is provided at the connecting portion 28. This locking structure may conform to ISO 80369-3, which allows connection to an ISO standard tube.

[0023] The separator 23 comprises a boat-shaped 24b that is liquid-tightly joined to the packaging material 11, and a locking portion 31 provided inside the boat-shaped 24b that is detachably locked to the spout body 22. A joint portion 27b for connecting with the packaging material 11 is provided on the outer circumferential surface of the boat-shaped 24b. The joint portion 27b is provided in a boat shape so as to be continuous around the entire circumference of the boat-shaped 24b and is formed to have the same outer circumferential shape as the joint portion 27a of the boat-shaped 24a of the spout body 22. The locking portion 31 is formed in a concave shape into which the protruding portion 25 of the spout body 22 is inserted and locked. In this embodiment, it has a structure that allows it to be locked by screwing or the like to a connecting portion 28 provided on the protruding portion 25 of the spout body 22, and by locking the locking portion 31 to the connecting portion 28, the connecting portion 28 can be covered in a liquid-tight manner.

[0024] Furthermore, a substantially cylindrical insertion projection 32 is provided on the inside of the recessed shape of the locking portion 31, which can be inserted into the circular hole 26b of the through hole 21a of the spout body 22 and fitted in a liquid-tight manner. The insertion projection 32 is provided with a through hole 21b that penetrates the locking portion 31 and is always open at both ends. The through-hole 21b is provided with a holding portion 33 capable of holding the contents within the through-hole 21b. Specifically, a closing piece is provided protruding into the through-hole 21b at one end of the opening, with an opening area smaller than the cross-sectional area of ​​the through-hole 21b.

[0025] When the separator 23 is locked to the spout body 22, the insertion projection 32 of the locking portion 31 of the separator 23 is inserted into and fitted into the through hole 21a of the projection 25 of the spout body 22, and the connecting portion 28 of the projection 25 of the spout body 22 is locked to the locking portion 31 of the separator 23. In this state, the spout 20 is liquid-tightly connected to the protruding portion 25 of the spout body 22 and the locked portion 31 of the separator 23, and the through hole 21a of the spout body 22 and the through hole 21b of the locked portion 31 communicate with each other, thereby forming a through hole 21 in the spout 20 that is always open at both ends. Furthermore, the boat shape 24a of the spout body 22 and the boat shape 24b of the separator 23 are arranged adjacent to each other, and the joint portion 27a of the boat shape 24a and the joint portion 27b of the boat shape 24b are arranged adjacent to each other and in the same orientation. The spout body 22 and the separator 23 are molded from a resin that can be welded to the innermost layer of the packaging material, and are made of resins such as polyethylene or polypropylene.

[0026] The container 10 may also be manufactured by welding such a spout 20 to the inner surface of the packaging material 11 and forming a peripheral seal portion 12 by providing an opening for accommodating the contents. At this time, the spout 20 is in a state where the spout body 22 and the separator 23 are locked together and integrated, the boat shape 24a of the spout body 22 and the boat shape 24b of the separator 23 are adjacent to each other, and the joint portion 27a and the joint portion 27b are adjacent to each other in the same direction. For example, the spout 20 is positioned between two opposing packaging materials 11, and the joining portions 27a and 27b are welded together to the inner surface of the packaging material 11, so as to traverse between the left and right peripheral seal portions 12 and be continuous with each peripheral seal portion 12. Furthermore, a notch 15 is provided at a position corresponding to the boundary between the boat shape 24a of the spout body 22 and the boat shape 24b of the separator 23 to facilitate the breaking of the packaging material 11. This makes it possible to create an empty container 10 with the bottom of the containment portion 13 open. The container 10 can also be manufactured by other methods; for example, a single sheet of packaging material 11 may be folded and a spout 20 may be placed in between and welded, or a spout 20 may be placed inside a tubular packaging material 11 and welded.

[0027] Next, a method for manufacturing a container containing contents using such an empty container 10 will be described. In this embodiment, the contents contained in the container 10 are substances that are contained in a fluid state, and after sealing, their fluidity decreases and they become semi-solid, undergoing changes due to oxidation. This substance may be a low-viscosity liquid or a high-viscosity viscous liquid, and can be various solutions, mixtures, dispersions, solid-liquid mixtures, etc., as long as it is fluid when contained. In this context, a decrease in fluidity after sealing means that the diffusion rate decreases compared to when the contents were contained. Due to semi-solidification, when no external physical action is applied, the contents localized in a part of the containment section 13 will remain in approximately the same position. Changes due to oxidation mean that the color, taste, and other characteristics change or the components change as oxidation occurs. The contents of this embodiment undergo a change in color due to oxidation, and when a part of it is oxidized in a semi-solid state, the part with the changed color remains without diffusing.

[0028] First, a container 10 is prepared, which has an empty storage section 13 with an opening. This container 10 does not have a peripheral seal section 12 at the bottom, so that the opening of the storage section 13 is provided at the bottom. With the bottom of the container 10 facing upwards, the contents are placed in the storage section 13 through the opening in a fluid liquid state, and the entire container is sealed by forming a peripheral seal section 12 at the opening.

[0029] At this time, air remains inside the sealed container 10, and the contents are oxidized by the oxygen contained in the remaining air. However, since the contents are liquid and highly fluid at the initial stage of sealing, the oxidized contents easily diffuse into the contents.

[0030] Subsequently, the contents sealed within the containment section 13 lose fluidity over time or through various processes, and change from a liquid state to a semi-solid state. In this embodiment, the container 10 containing the sealed contents is subjected to a predetermined heat treatment, which reduces fluidity and causes it to semi-solidify. This is how a container containing the contents is manufactured. At this stage, the oxygen in the air that remained in the container 10 during sealing has already been consumed by oxidizing the contents, so the amount of oxygen remaining in the container 10 has decreased significantly, and the contents do not oxidize even after the fluidity has decreased. Therefore, it is possible to manufacture containers containing the contents in a state where the contents do not undergo localized discoloration due to oxidation.

[0031] Next, we will explain how to use the container with the contents inside. To use such a container 10, as shown in Figure 5, grasp the spout 20 from the outside of the packaging material 11 and separate and remove the separator 23 from the spout body 22. Here, the protruding portion 25 of the spout body 22 and the locking portion 31 of the separator 23 are screwed together, so they can be separated by twisting the locking portion 31 relative to the spout body 22. At this time, since the packaging material 11 is attached to both the spout body 22 and the separator 23, twisting the separator 23 relative to the spout body 22 applies a shearing force to the packaging material 11, causing it to break starting from the notch 15. By separating the separator 23 from the spout body 22, the packaging material 11 can be separated and removed together with the separator 23.

[0032] This allows the connecting portion 28 provided on the protruding portion 25 of the spout body 22 to be exposed. Then, after connecting the end of the tube 16 for discharging the contents to the connecting part 28, the contents can be discharged from the tube 16 and used.

[0033] As described above, with the container 10 of this embodiment, a three-dimensional spout 20 with both ends always open is housed and positioned inside the container. Therefore, when the container is sealed with contents inside, no large space is formed inside the container that does not directly contact the contents. As a result, oxygen from this space does not gradually enter the storage section 13 where the contents are stored by permeating the spout 20. This prevents the contents near the spout 20 from being oxidized after their fluidity has decreased, especially when the container holds substances that lose fluidity after sealing and undergo changes due to oxidation. Thus, it is possible to reliably prevent the contents accumulating near the spout 20 from being oxidized.

[0034] Furthermore, in the container 10 of this embodiment, the spout 20 is configured to be separable, and the packaging material 11 is continuously joined to the outer surface of each spout in the circumferential direction. Therefore, by separating and removing the spout 20, the shape can be changed, making it easier to realize various shapes required during use and improving the degree of design freedom. Furthermore, even if the spout 20 is configured to be separable, air does not remain between the separated spout 20 and the packaging material 11, nor does any remaining air move between them. This prevents oxygen in the air from entering the containment section 13 and oxidizing the contents.

[0035] Furthermore, in the container 10 of this embodiment, the spout 20 has a spout body 22 and a separator 23 that is detachably locked to the integral side of the spout body 22, and the packaging material 11 can be separated together with the separator 23. Therefore, by separating and removing the separator 23 of the spout 20, the packaging material 11 covering the separator 23 can be removed together. As a result, there is no need to perform a two-step operation of breaking the packaging material 11 to open it and then separating the separator 23 of the spout 20, and the breaking of the packaging material 11 and the separation of the separator 23 can be done in one step, making it easy to open the container.

[0036] Furthermore, in the container 10 of this embodiment, a holding portion 33 for holding the contents is provided protruding into the through-hole 21 of the separator 23. Therefore, when the separator 23 is separated from the spout body 22 during opening, it is possible to prevent contents remaining in the packaging material 11 joined to the separator 23 and contents remaining in the through-hole 21 of the separator 23 from leaking out of the through-hole 21 of the separator 23 after separation.

[0037] Furthermore, in the container 10 of this embodiment, the spout body 22 is provided with a connecting portion 28 for connecting to other components, and the connecting portion 28 is covered in a liquid-tight manner by a separator 23. Therefore, the contents do not come into contact with the connecting portion 28 until the container is used. As a result, when in use, the contents do not adhere to the connecting portion 28, making it easy to connect other components to the connecting portion 28, and the contents that do adhere to the connecting portion 28 do not further adhere to the surrounding area, making it hygienic.

[0038] Furthermore, in the container 10 of this embodiment, the joint portion 27a between the spout body 22 and the packaging material 11 on the outer surface and the joint portion 27b between the packaging material 11 on the outer surface of the separator 23 have the same outer surface shape. Therefore, it is easy to join the packaging material 11 to both. Also, after joining, no deformation of the packaging material 11 occurs between the portion joined to the spout body 22 and the portion joined to the separator 23, so that joining defects such as cracks do not occur. Furthermore, since the spout body 22 and the separator 23 are positioned adjacent to each other and the packaging material 11 is joined to each, gaps are less likely to form between the spout body 22, the separator 23, and the packaging material 11, making it difficult for air to remain in this area.

[0039] The above embodiments can be modified as appropriate within the scope of the present invention. For example, in the above embodiment, the locking portion 31 of the separator 23 is screwed onto the protruding portion 25 of the spout body 22 for locking, but other locking methods can also be employed. Furthermore, the spout body 22 and the separator 23 may be integrally molded in a manner that allows for easy breakage. In the above embodiment, the spout body 22 and the separator 23 are provided with boat shapes 24a and 24b to join with the packaging material 11. However, the part to which the packaging material 11 is joined may have other shapes, and is not particularly limited as long as the shape allows the packaging material 11 to be continuously joined in the circumferential direction to both the spout body 22 and the separator 23. Furthermore, in the above embodiment, an example was described in which a connecting portion 28 is provided on the protruding portion 25 of the spout body and a tube 16 is connected to discharge the contents. However, the connecting member is not limited to a tube 16 and can be connected as appropriate. The present invention can also be applied to cases in which the contents are discharged directly from the protruding portion 25 of the spout body 22. [Explanation of symbols]
