Description

[Technical Field]

[0001] The present invention relates to an adhesive container that contains an adhesive therein. [Background technology]

[0002] When an adhesive storage container having a flexible container body containing adhesive and an outlet member removably attached to the container body is used, for example, by attaching it to a device equipped with a nozzle for applying adhesive, once the adhesive contained inside the container body has been used up, it is necessary to remove the adhesive storage container from the device and replace it with a new adhesive storage container.

[0003] However, in conventional adhesive storage containers, when the container is replaced, the outlet path formed in the outlet member for discharging the adhesive to the outside of the container is left open, which causes the adhesive remaining inside the outlet path and the hose connecting the outlet path to the nozzle to come into contact with the outside air and harden, resulting in a problem of clogging.

[0004] Furthermore, if the viscosity of the adhesive contained inside is low, there is a problem that the adhesive remaining inside the outlet passage or the hose connected to the outlet passage may flow back and spill out when the adhesive is replaced. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE INVENTION

[0010] The adhesive container according to this embodiment will be described below. The adhesive storage container 100 according to this embodiment is used by being attached to an adhesive application device 200, for example, as shown in FIG.

[0011] The adhesive application device 200 includes, for example, a pressure mechanism 210 for pressurizing the adhesive storage container 100 and discharging the adhesive therein to the outside, a nozzle 220 connected to the adhesive storage container 100 for discharging the adhesive to the outside, and a connecting flow path 230 connecting the adhesive storage container 100 and the nozzle 220.

[0012] The pressurizing mechanism 210 includes, for example, a pressurizing chamber 211 that accommodates the adhesive storage container 100 therein, and a pressure control mechanism 212 that controls the pressure within the pressurizing chamber 211, as shown in FIG.

[0013] The pressure control mechanism 212 includes, for example, a gas cylinder (not shown) for introducing gas into the pressurized chamber 211 to increase the pressure in the pressurized chamber, a gas inlet path (not shown) for guiding the substrate in the gas cylinder to the pressurized chamber, a flow rate control device (not shown) such as a valve provided on the gas inlet path to control the flow rate of the gas flowing through the gas inlet path, and a flow rate control unit (not shown) for controlling the flow rate control device.

[0014] The nozzle 220 is not particularly limited as long as it can discharge the adhesive contained in the adhesive container 100 to the outside.

[0015] The connection flow path 230 is formed by a flow path forming member 231 such as a hose, for example, whose both ends are connected to the adhesive storage container 100 and the nozzle 220, and through which adhesive can flow inside.

[0016] The adhesive storage container 100 of this embodiment is capable of discharging the adhesive stored inside to the outside by being stored in the pressurized chamber 211 described above and being pressurized, and comprises a flexible container body 1 in which the adhesive is stored, and an outlet member 2 which is removably attached to the container body 1 and has an outlet path 2a for guiding the adhesive in the container body 1 to the outside.

[0017] Container body 1 is, for example, bag-shaped and has an opening 1a for putting adhesive in and taking it out. This container body 1 is preferably one that can be easily deformed by being pressurized in, for example, pressurized chamber 211, and can extrude the adhesive stored inside to the outside, and examples of such container body include those formed from resins such as polyethylene, polypropylene, polyethylene terephthalate, nylon, or flexible films such as aluminum.

[0018] 2 or 3, the outlet member 2 is connected to the connection flow path 230 of the adhesive application device 200 described above via a joint member 3 or the like, and forms an outlet path 2a that leads the adhesive from an opening 1a formed in the container body 1 to the connection flow path 230. This outlet member 2 is attached to the opening 1a provided in the container body 1 of the adhesive storage container 100 when a new adhesive storage container 100 is set in the adhesive application device 200, and is removed from the container body 1 when replacing it with the next adhesive storage container 100.

[0019] In this embodiment, the outlet member 2 includes a cylindrical body 21 having a cylindrical shape or the like, and a disk-shaped flange body 22 attached to one end of the cylindrical body 21, and an inlet E of the outlet path 2a is formed on an end surface 22a of the flange body 22 opposite to the side in contact with the cylindrical body 21 (i.e., the container body side). The cylindrical body 21 and the flange body 22 are preferably formed integrally, and in this embodiment, they are preferably formed from a metal such as stainless steel or a resin.

[0020] Here, the flange body 22 is sized so that the entire outer peripheral edge is positioned outside the outer peripheral surface of the cylindrical body 21, and with the flange body 22 positioned so as to block the opening 1a of the container body 1, the discharge member 2 is fixed to the container body 1 by a fixing mechanism 4 (for example, it can be held down by a screw cap 42 that fits into a screw thread 41 provided on the outer peripheral surface of the opening 1a of the container body 1) that fits into the side peripheral surface of the cylindrical body 21 and fixes it to the container body 1.

[0021] In this embodiment, the central axes of the aforementioned cylindrical body 21 and flange body 22 are arranged coaxially, and the inlet E of the outlet path 2a formed in the flange body 22 is also formed to be positioned coaxially with these.

[0022] Therefore, the adhesive storage container 100 of this embodiment comprises a sealing member 5 that is removably attached to the discharge member 2 to seal the entrance E of the discharge path 2a, and an attachment structure 6 that attaches the sealing member 5 to the discharge member 2, and the sealing member 5 is configured to be movable between a blocking position in which it blocks the entrance E of the discharge path 2a and an opening position in which the sealing member 5 opens the entrance E of the discharge path 2a while maintaining an engaged state with the attachment structure 6.

[0023] In this embodiment, the sealing member 5 is plate-shaped and provided at the base end of a long flow path securing member 7 that is inserted into the container body 1 of the adhesive storage container 100, and this sealing member 5 is configured to engage with the mounting structure 6 so that the flow path securing member 7 can be connected to the outlet member 2.

[0024] As shown in Figure 4, the mounting structure 6 includes a pair of ribs 61 arranged opposite each other across the entrance E of the outlet path 2a, which opens into the end face of the outlet member 2 on the container body 1 side (i.e., the end face of the flange body 22), and a pair of pressure plates 62 formed to extend integrally from the inner surface of each rib 61 toward the opposing rib 61.

[0025] The sealing member 5 is formed so that its width dimension approximately matches the dimension between the inner surfaces 61a of each of the ribs 61 and its thickness dimension approximately matches the gap dimension between the pressure plate 62 and the end surface 22a of the flange body 22, and this sealing member 5 is configured to engage with the mounting structure 6 by being slidably inserted between each of the ribs 61.

[0026] By adopting such a structure, in this embodiment, the sealing member 5 is configured to be slidable between at least two positions: a closed position (Figure 5) in which it overlaps with the entrance E of the outlet path 2a, and an open position (Figure 6) in which it does not overlap with the entrance E of the outlet path 2a.

[0027] The flow path securing member 7 is made up of an engagement plate 71 for engaging with the lead-out member 2 and a flow path forming member 72 extending upright from the engagement plate 71.

[0028] The engagement plate 71 is, for example, a plate-like member, a part of which forms the sealing member 5. The engagement plate 71 has an opening 71a formed therein, which is in communication with the inlet E of the outlet path 2a formed in the outlet member 2.

[0029] The flow path forming member 72 is an elongated member that is inserted into the container body 1. In this embodiment, the flow path forming member 72 has a shape in which two elongated rectangular flat plates are crossed so that their face plates are perpendicular to each other, and has a cross shape in a cross section taken along a plane perpendicular to the longitudinal direction. By being inserted into the container body 1, the flow path forming member 72 can form a flow path through which the adhesive flows along the longitudinal direction between the flat plates. A notch is formed in the flat plate at the portion of the flow path forming member 72 that contacts the engagement plate 71, and a communication space 72a is formed so that the adhesive that flows along the flat plate can flow into an opening 71a formed in the engagement plate 71.

[0030] In this embodiment, the engagement plate 71 and the flow path forming member 72 are both made of resin and are molded integrally with each other. The engagement plate 71 and the flow path forming member 72 may be made of the same material or different materials. The material from which these members are made is not particularly limited as long as it is not altered by the contents contained in the container body 1. The flow path forming member 72 is preferably removably removable by wiping or the like to easily remove adhesives contained as contents, and is preferably flexible and pliable so that it can bend flexibly inside the container body 1 and will not break when pressure is applied. Examples of materials that can impart the above-mentioned properties to the flow path forming member 72 include polypropylene and polyethylene. The size of the engagement plate 71 is preferably smaller than the diameter of the opening 1 a of the container body 1 . Furthermore, the length of the flow path forming member 72 is preferably such that the tip of the flow path forming member 72 sufficiently reaches the bottom of the container body 1 when the flow path securing member 7 is attached to the opening 1a of the container body 1.

[0031] In order to position the sealing member 5 at these two positions, the closed position and the open position, in this embodiment, the lead-out member 2 and / or the sealing member 5 are provided with a positioning mechanism 8 for positioning the sealing member 5.

[0032] As an example of the positioning mechanism 8, in this embodiment, a protrusion 81 is formed on the end face (here, 22a) of the lead-out member 2 that comes into contact with the sealing member 5, and a recess 82 that engages with this protrusion is formed on the end face (here, end face 71b of the engagement plate 71) of the sealing member 5 that comes into contact with the lead-out member 2.

[0033] In this embodiment, when the recess 82 of the sealing member 5 engages with the protrusion 81, the sealing member 5 is positioned at the closed position. On the other hand, when the protrusion 81 engages with the opening 71a formed in the engagement plate 71, the sealing member 5 is positioned at the open position.

[0034] It is preferable that the protrusion 81 formed on the lead-out member 2 is of a height and size that allows the user to feel the engagement of the protrusion 81 and the recess 82 when the user manually slides the engagement plate 71 to engage them, and that the height and size are such that the protrusion 81 can easily overcome the edge of the recess 71c by manual sliding operation.

[0035] In this embodiment, the aforementioned protrusion 81 is annular and formed along the outer periphery of the inlet E of the outlet path 2a, and the recess 82 is cylindrical and sized to fit exactly around the outer periphery of this protrusion 81.

[0036] When the sealing member 5 is positioned in the open position described above, it is preferable that the aforementioned outlet path 2a, the inlet E of the outlet path 2a, the opening 71a formed in the engagement plate 71, and the flow path forming member 72 are all arranged coaxially.

[0037] <Effects of this embodiment> According to the adhesive storage container 100 of this embodiment, by placing the sealing member 5 in the open position, the opening 71a formed in the engagement plate 71 and the outlet path 2a are connected to each other, and the adhesive stored in the container body 1 can be discharged to the outside, while when the adhesive inside the adhesive storage container 100 is used up and the adhesive storage container 100 is replaced with a new one, by placing the sealing member 5 in the closed position, the opening 71a formed in the engagement plate 71 is blocked from the outlet path 2a and the inlet E of the outlet path 2a can be sealed with the sealing member 5. As a result, when the adhesive storage container 100 is replaced with a new one, it is possible to prevent the adhesive remaining in the outlet path 2a and / or inside the hose connected to the outlet path 2a from hardening due to exposure to the outside air.

[0038] Furthermore, as mentioned above, when replacing the adhesive storage container 100, the entrance E of the outlet path 2a can be sealed with the sealing member 5, so that even if the viscosity of the adhesive stored inside is relatively low, it is possible to prevent the adhesive remaining inside the outlet path 2a or inside the hose, etc. from spilling out.

[0039] The sealing member 5 is slid between a blocking position where it blocks the entrance E of the outlet path 2a and an opening position where it opens the entrance E of the outlet path 2a, so that the entrance E of the outlet path 2a can be sealed or opened by the sealing member 5 with as simple a configuration and operation as possible.

[0040] The device is provided with a positioning mechanism 8 in which a protrusion 81 and a recess 82 engage with each other, and the sealing member 5 can be slid to be positioned at two positions, a closed position and an open position, so that it is possible to easily sense by touch that the sealing member 5 has been positioned at each position.

[0041] When the sealing member 5 is positioned in the open position described above, the aforementioned outlet path 2a, the inlet E of the outlet path 2a, the opening 71a formed in the engagement plate 71, and the flow path forming member 72 are all arranged coaxially, so that, for example, when external pressure is applied to the container body 1 by the pressure mechanism 210 of the aforementioned adhesive application device 200, the adhesive contained inside the container body 1 can be passed along the flow path forming member 72, through the opening 71a formed in the engagement plate 71, and smoothly discharged to the outside from the outlet path 2a.

[0042] Since the flow path securing member 7 and the sealing member 5 are integrally formed, the number of parts does not increase and the structure can be made as simple as possible.

[0043] Since the sealing member 5 can be slid and removed from the outlet member 2, the sealing member 5 and / or the flow path securing member 7 formed integrally with the sealing member 5 can be made disposable, and the user can choose whether to dispose of or reuse these members depending on the situation.

[0044] The present invention is not limited to the above-described embodiment. The structural drawing of the lead-out member is not limited to the one described above, and may be any other drawing as long as a part of the outer peripheral edge of the flange body is positioned outside the outer peripheral surface of the cylindrical body, for example. Alternatively, the inlet of the outlet passage may be formed on the end face of the cylindrical body rather than on the flange body, and the flange body may be attached to the outlet side of the outlet passage of the cylindrical body. In this case, the outlet member may be fixed to the container body by fitting the outer peripheral surface of the cylindrical body to the inner peripheral surface of the opening of the container body, as shown in Fig. 7, for example. The outlet member may not have a flange body, and one end face of the cylindrical body may perform the function of the flange body described above.

[0045] The shape of the flow path ensuring member is not limited to the one described above, and any long, elongated member that can be inserted into the container body and that can form a flow path inside the container body that can guide the adhesive to the opening even when the container body is crushed by external pressure can be used, and various shapes that have been used conventionally can be used. For example, as shown in Figure 8, the flow path forming member may be cylindrical and have approximately the same diameter as the opening formed in the engagement plate, or may be a cylindrical flow path forming member with multiple holes formed along the longitudinal direction of the outer circumferential surface.

[0046] In the above-described embodiment, the sealing member is formed by a single engagement plate, but this is not limiting and the sealing member may be formed by a plurality of adjacent engagement plates, as shown in Fig. 9. When forming the sealing member by arranging a plurality of engagement plates adjacent to each other in this manner, notches may be formed in the portions where the two engagement plates contact each other, so that the two engagement plates are in close contact with each other without any gaps. Note that the flow path forming member is omitted from Fig. 9 to make the drawing easier to understand.

[0047] The shape of the engagement plate is not particularly limited, but may be a generally elliptical shape as shown in Fig. 9. When actually replacing the flow path ensuring member, it is difficult for the user to see the position of the engagement plate of the flow path ensuring member, so the engagement plate must be inserted by sliding it blindly into the mounting structure. Therefore, it is preferable to use an engagement plate with rounded corners, such as the generally elliptical shape described above, because this allows the engagement plate to be smoothly attached to the mounting structure without having to adjust the angle at which the engagement plate is inserted to match the shape of the mounting member.

[0048] When forming a sealing member by arranging a plurality of engagement plates adjacent to each other, such as those having a generally elliptical shape as described above, a notch may be formed in part of the periphery in the major axis direction of the generally elliptical engagement plate, so that the periphery in the major axis direction of another engagement plate of the same shape fits snugly, as shown in Fig. 9. The notch may be formed in only one place, or in multiple places.

[0049] The positioning mechanism for positioning the sealing member at two positions, the closed position and the open position, is not limited to the one described above. For example, as shown in FIG. 10, by reducing the size of the protrusions and recesses and increasing their number to multiple, it is possible to position the sealing member at two positions, the closed position and the open position, while reducing the resistance when sliding the engaging plate that forms the sealing member.

[0050] The sealing member need only be removably attachable to the outlet member via an attachment mechanism, and does not necessarily have to be formed integrally with the flow path securing member. Furthermore, the attachment mechanism may be any mechanism that can detachably attach the sealing member to the lead-out member, and is not limited to a mechanism that attaches the sealing member by sliding it.

[0051] The type of adhesive contained inside is not particularly limited and any type may be used, but a one-component moisture-curing adhesive that hardens upon contact with the outside air is preferred, and in particular, one-component moisture-curing adhesives such as urethane resin-based, modified silicone resin-based, silylated urethane resin-based, and silicone-based adhesives are more preferred.

[0052] The adhesive storage container is not limited to those used in the adhesive application device described above, but may be used in other application devices, or may be used alone.

[0053] In addition, various modifications and combinations of the embodiments may be made as long as they do not deviate from the spirit of the present invention. [Explanation of symbols]
