Description

  The present invention relates to a container for separating and storing each component of a multi-component mixed resin and mixing each component during use.

  As a container for various food-related products such as beverages, it is common to use a spout-equipped packaging bag in which the spout is fixed so that the flange provided on the outer periphery of the spout tube is sandwiched between films. Is known to. Also, "A related beverage container with a polymer film multi-chamber pouch with an internal frangible seal to contain the fluid, and a resealable appliance for storing and dispensing two different flavor liquids, etc." A multi-chamber packaging bag with a spout such as (Patent Document 1, FIG. 1) has also been proposed.

JP 2006-511409 A

  When a conventional multi-room packaging bag with a spout is used as a beverage container, even if the beverage flows into the tube portion of the spout during storage, the stored beverage generally has a relatively low viscosity, so If the container is set up so as to be positioned above, the beverage in the cylinder part flows out into the storage chamber, so that the beverage stays in the cylinder part even if the openable seal is opened and the flavor liquid is mixed with the beverage. It is difficult to cause poor mixing.

  However, as a container for storage and mixing of multi-component mixed type resins such as epoxy resins and polyurethane resins, it is necessary to thoroughly mix components such as the main agent and curing agent at a predetermined appropriate ratio immediately before use. And when using such a multi-chamber packaging bag with a spout, which can be attached to the container to enable the resin after mixing to be poured into the groove or hole without changing the container In this case, a component having a relatively high viscosity flows into the spout tube during storage, and even if the container is erected so that the spout is positioned above, the component that has flowed into the tube tends to stay in the tube. is there. In this state, even if the openable seal is opened and each component is sufficiently mixed, the unmixed component may remain.

  In such a case, even if the resin in the packaging bag is applied and injected as it is onto the object to be applied, the unmixed components are not cured, which may result in poor adhesion, poor appearance, and poor waterproof performance.

  The present invention has been made in view of the above problems, and each component of the multi-component mixed resin is separated and stored in one packaging bag, stored, mixed, and mixed without changing the container. It is an object of the present invention to provide a multi-chamber packaging bag with a spout in which a later resin can be poured into a groove or a hole and an unmixed component is hardly generated.

  In one embodiment of the present invention, a storage chamber formed of one or a plurality of films, a part of the storage chamber that can be opened, a releasable seal that forms a plurality of storage chambers, and a storage chamber in the storage chamber A spout for taking out objects to the outside, this spout has at least a cylindrical portion, and a part of the outer peripheral portion of the cylindrical portion of the spout is sandwiched and fused by the outer peripheral portion of the film, Provided is a packaging bag having a spout fixed to a film and a sealing portion provided in a storage chamber side opening of the spout.

  The packaging bag according to one aspect of the present invention faces the spout because the storage portion of the spout is provided with a sealing portion that prevents the stored item from flowing into the cylindrical portion of the spout at the storage chamber side opening. The component stored in the storage chamber is prevented from flowing into the cylindrical portion of the spout that becomes a liquid pool by the sealing portion, and the component is prevented from staying in the cylindrical portion of the spout. As a result, each component of the multi-component mixed resin is separated and stored in a single packaging bag, stored, mixed, and attached to a spout with a nozzle, without mixing and changing the container. It is possible to provide a multi-chamber packaging bag with a spout in which resin can be injected into a groove or a hole and an unmixed component is hardly generated.

  Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. Corresponding components are denoted by common reference symbols throughout the drawings.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. FIG. 1A shows a packaging bag 10 and a spout 12 for separating and packaging components such as so-called main agent and curing agent of a two-component mixed resin such as epoxy resin and polyurethane resin according to an embodiment of the present invention. The top view of the nozzle 15 with which it mounts | wears is shown. 1B is a side view of the packaging bag 10 and the nozzle 15, and FIG. 1C is a perspective view of the packaging bag 10 and the nozzle 15.

  As shown in FIG. 1, the packaging bag 10 is bonded to the outer peripheral portion of the two films 11 in a bag shape by fusing the flange portion 123 provided on the outer periphery of the spout 12 below the cylindrical portion 122. Thus, the storage chamber 14 formed between the two films 11 bonded to each other in the form of a fusion seal 13a, 13b, 13c, 13d is formed into two storage chambers 141, 142 by an openable seal 14a. It is configured by partitioning. A nozzle 15 can be attached to the packaging bag 10 via the spout 12.

  Of the two storage compartments 141 and 142, the first storage compartment 141 in contact with the spout 12 stores the first component of the two-component mixed resin stored in the packaging bag 10 and does not contact the spout 12. The second storage compartment 142 stores a second component that hardens when mixed with the first component. Which of the so-called main agent and curing agent is the first component is not particularly limited in the present embodiment.

  The film 11 is a transparent or translucent resin material having flexibility, for example, a single material such as nylon, polyethylene, or PET having a thickness of 100 μm or more, 103 μm or more, 130 μm or less, or 200 μm or less, or a composite material thereof. Consists of. In this case, when the components stored in the storage chamber 141 or 142 are colored differently by coloring or the like, the mixing state can be visually recognized when the components are mixed. The film 11 is a layer having a light-shielding / light-reducing function, such as using a colored resin, a metal foil such as aluminum, a vapor-deposited metal film, etc. depending on the characteristics and purpose of the two-component mixed resin, You may have the layer which interrupts permeation | transmission of gas, a printing layer, etc.

  When the two-component mixed resin is stored and transported, the openable seal 14a reliably separates the components stored in the storage chambers 141 and 142 and uses the two-component mixed resin. Is a seal that can be easily opened. By opening the openable seal 14a, the storage compartments 141 and 142 partitioned by the openable seal 14a become a single storage compartment 14, and the components stored separately in the storage compartments 141 and 142 are , Will be able to mix with each other.

  As shown in FIGS. 2 (a) and 2 (b), the openable seal 14a sandwiches a multilayer film tape 14b that can be delaminated between two films 11, and melts the multilayer film tape 14b and the film 11 together. It can be obtained by wearing it. For example, an easy peel film (trade name) manufactured by J Film Co., Ltd. can be used for the multilayer film tape 14b. The openable seal 14a does not necessarily need to use the multilayer film tape 14b as long as it can be easily opened during use while securely forming the storage chambers 141 and 142 during storage and transportation. It is also possible to use a film tape that causes peeling instead of the multilayer film tape 14b, or to partition the storage chamber from the outside of the packaging bag 10 using a clip or the like. Further, in the illustrated configuration, the openable seal 14a is provided at one location so as to cross the storage chamber 14 and constitutes the storage small chambers 141 and 142. However, a plurality of or branchable openable seals 14a are provided. It is also possible to configure three or more storage compartments by providing the above.

  The openable seal 14a is opened when the multilayer film tape 14b is delaminated by picking up the film 11 at the center of the front and back of the storage chamber 141 or 142 with fingers and stretching the film 11 with each other. When the openable seal 14a is opened, the storage compartments 141 and 142 become the communication storage chamber 14, and the components stored separately can be mixed.

  The spout 12 serves as a spout for taking out the two-component mixed resin stored in the packaging bag 10 from the packaging bag 10 after mixing. As shown in FIG. 3, the spout 12 is a substantially cylindrical member opened upward, and has a spout 125 at the upper end of the cylindrical portion 122 and a cap (not shown) or nozzle 15 at the upper outer peripheral surface. A screw portion 121 for attaching the housing, a flange 123 at the bottom, a storage chamber side opening 124 at the lower end, and a sealing film 126 as a sealing portion so as to close the storage chamber side opening 124. The tube portion 122 is fused to the lower end surface. It is desirable that the cylindrical portion 122 of the spout 12 has an inner diameter sufficient to easily take out the two-component mixed resin after mixing the components. Specifically, the inner diameter of the cylindrical portion 122 can be φ10 or more, or φ15 or more, and can be φ20 or less, or φ25 or less. Moreover, the length of the cylinder part 122 can be 30 mm or more or 35 mm or more, and can be 40 mm or less or 45 mm.

  As shown in FIG. 1, the flange 123 is sandwiched between the film 11 as shown in FIG. 2D, as shown in FIG. 2 (d), as shown in FIG. 2 (d). And the spout 12 is fixed to the film 11 by fusing the outer peripheral surface of the flange 123 and the film 11 without a gap. In addition, if the spout 12 can be securely fixed to the film 11 without a gap, as shown in FIGS. 5B and 5C, the presence / absence, number, size, and shape of the flange are not limited. .

  The sealing film 126 constituting the sealing portion closes the storage chamber side opening 124 of the spout 12 as shown in FIGS. 2 (a), 4, 5 (a), and 6 (a). As described above, the components stored in the storage chamber 141 facing the spout 12 are prevented from flowing into the cylindrical portion 122 in an unmixed state. This prevents unmixed components from staying in the spout cylinder 122 and prevents unmixed components from being produced in the packaging bag 10 when the openable seal 14a is opened and the components are mixed. To do. After opening the openable seal 14a and mixing each component, the packaging bag 10 is exposed to the outside by breaking through the sealing film 126 with a rod-shaped article having sufficient strength such as the tip of the nozzle 15 or a driver. On the other hand, the two-component mixed resin in the packaging bag 10 can be taken out through the spout 12.

  The sealing film 126 is a flexible transparent or translucent resin material such as nylon, polyethylene, PET or the like having a thickness of 100 μm or more, or 103 μm or more, 130 μm or less, or 200 μm or less, or these When the packaging bag 10 made of a composite material and containing each component is stored, and when the openable seal 14a is opened and the components are mixed, the strength is required to prevent damage. Depending on the characteristics and purpose of the stored item, a layer having a light shielding / dimming function, a layer blocking moisture and gas permeation, or the like may be provided by a metal foil such as aluminum, a deposited metal film, or the like. When such a multilayer film is used as the sealing film 126, at least the layer in contact with the spout 12 needs to be a thermoplastic resin because it is fused to the lower end surface of the spout 12.

  In addition, instead of the sealing film 126, as shown in FIG. 4B, the surface on the storage chamber side does not substantially have unevenness that becomes a liquid pool, and has sufficient strength from the spout 125. When the sealing cap 127 is dropped into the storage chamber 14 by being pushed by a stick or the like and is opened, the sealing cap 127 is fitted into the storage chamber side opening 124, or as shown in FIG. 4 (c). 12 can be sealed by forming the sealing wall 128 integrally with the spout 12 or the like. It is possible to prevent the components stored in the storage chamber 141 from flowing into and staying in the cylindrical portion 122 in an unmixed state.

  The nozzle 15 is a tapered tubular member used when the two-component mixed resin stored in the packaging bag 10 is poured into a groove, a hole, or the like after mixing. As shown in FIGS. The taper portion 151 has a cap portion 152 at the bottom. On the inner surface of the cap portion 152, there is a screw portion 153 that is fixed to the spout 125 of the spout 12 by fitting with the screw portion 121 of the spout 12.

  For storing each component of the two-component mixed resin in the packaging bag 10, for example, the flange 123 of the spout 12 to which the sealing film 126 is fused so as to cover the storage chamber side opening 124 and the multilayer film tape 14 b are used. By forming the fusion seals 13a, 13b, 13c and the openable seal 14a while being sandwiched between the two films 11, the packaging bag 10 in which the fusion seal 13d is opened can be obtained. After the first component is injected into the storage compartment 141 of the packaging bag 10 and the second component is injected into the storage compartment 142, the fusion seal 13d can be formed.

  When the two-component mixed resin stored in the packaging bag 10 is used, first, when the film 11 at the center of the front and back of the storage chamber 141 or 142 is picked with fingers and spread together, a multilayer film tape The delamination occurs in 14b, the openable seal 14a is opened, the storage chambers 141 and 142 become the communication storage chamber 14, and the separately stored components can be mixed. In this state, the packaging bag 10 is squeezed by hand, and after each component is sufficiently mixed, a sufficiently strong stick such as a screwdriver is inserted into the spout 125, and the sealing film 126 is pierced. The two-component mixed resin can be taken out from the packaging bag 10 through 125. At this time, as shown in FIG. 6, if the nozzle 15 is attached to the spout 12, it becomes easy to inject the two-component mixed resin into the grooves and holes.
