Abstract
Description
Technical Field
[0001] The present invention relates to a transfer tool for an adhesive bag, which is used by attaching it to an adhesive bag when transferring an adhesive bag filled with a liquid or gel-like adhesive to another container or storage part. The present invention also relates to a transfer set for transferring the adhesive in the adhesive bag to another place, including this transfer tool.
Background Art
[0002] Several caps and mounting tools used by attaching them to bags or containers containing liquids are disclosed.
[0003] For example, conventionally, as a bag clamping cap fixed to a bag body cutting part, a double funnel-shaped detachable bag clamping cap provided with a cylindrical body 1 that serves as a discharge passage when the contents of the bag are discharged is disclosed (see Patent Document 1).
[0004] This bag clamping cap is disclosed to include a funnel-shaped cylinder E in which a male screw is formed on the outer surface of the cylindrical body 1 and a funnel body 2 is formed at one end of the cylindrical body 1, and a cylindrical body 3 that can be fitted onto the cylindrical body 1. A funnel-shaped cover D in which a funnel part 4 having substantially the same shape as the funnel body 2 is formed at one end of the cylindrical body 3, a screw-type stopper C having a female screw formed on the inner surface and capable of being screwed onto the cylindrical body 1, and a screw-type cap B capable of being screwed onto the other end of the cylindrical body 1. By cutting the corner part of the bag K, sandwiching the cut opening I of the bag K between two funnel-shaped cylinders E and the funnel-shaped cover D, and tightening the screw-type stopper C, the bag can be pressed in from both inside and outside, and this bag clamping cap A can be fixed to the cut part of the bag.
[0005] In addition, conventionally, as a detachable opening / closing device for a plastic container, a device in which a male screw-type member 170 and a female screw-type member 150 are screwed together while sandwiching the plastic container 10 is disclosed (see Patent Document 2).
[0006] This means that the female screw-type member 150 has a second cylindrical body 154 in which a second through hole 153 is formed along the axial direction of the female screw-type member 150. The female screw-type member 150 has a second screw thread 151 formed on its inner circumferential surface so that it is screwed onto the male screw-type member 170 on the outside with a screw gap 160 between it and the first screw thread 171. The vinyl container 10 is sealed by screwing the female screw-type member 150 and the male screw-type member 170 together so that the cut portion 13 of the vinyl container 10 is sandwiched in the screw gap 160.

[0007] [Patent Document 1] Tokuto-05497944 publication [Patent Document 2] Tokuto-03693574 publication [Disclosure of the Invention] [Problems that the invention aims to solve]
[0008] In this context, adhesive bags used in the workplace often contain a larger quantity of adhesive than is needed for a single application. In such cases, it is common practice to transfer the amount needed for a single application to another container, filling device, or the storage compartment of an injection device, or to transfer the remainder to a sealed storage container.
[0009] However, the conventional caps and opening / closing devices described above are primarily intended for use with bags containing general liquids. When used to transfer hardening adhesives, such as glues, into bags, the liquid flow area inside the cap and the adhesive near the attachment point harden or solidify, leading to problems where the cap becomes impossible to open or close, or the contents cannot be dispensed, after repeated use or over time.
[0010] Furthermore, conventional caps and opening / closing devices, including those mentioned above, were designed to be compressed by the interlocking fit of elastic members, or by the overlapping section of a multi-cylinder structure where the bag end is sandwiched between an inner cylindrical cover and an outer cylindrical cap. As a result, if the adhesive partially hardens after repeated use, solidified lumps or granular material may form within the compressed area, causing the interlocking structure to expand, resulting in insufficient fitting or clamping and potentially causing the bag to detach unintentionally.
[0011] Therefore, the object of the present invention is to provide a transfer tool or transfer set that can be attached to a storage bag for adhesives that have the potential to harden and solidify with use, and can be used repeatedly without problems even after a long period of time has passed, without the cap becoming impossible to open or close, or the contents becoming impossible to dispense.
[0012] Furthermore, a key objective is to provide a transfer tool or transfer set that prevents the adhesive from unintentionally detaching from the bag due to partial hardening after repeated use. [Means for solving the problem]
[0013] To address the above issues, we are taking the following measures.
[0014] [1] The transfer dispensing device of the present invention is The corners of the adhesive-containing bag AP are cut to form a bag opening APE, and in this attached state, the bag opening APE serves as an outlet for transferring the adhesive contents to another container, while also being resealable. The "lower part" (1), consisting of a flanged male threaded cylinder, is partially inserted into the bag opening APE, which is created by cutting the corner of the adhesive-filled bag AP, The middle part (2) consists of a cylindrical body with an internal thread, whose tip is formed by a small diameter cylindrical part 23 with an external thread, and which is tightened around the outer circumference of the screw of the lower part 1 to clamp and secure the corner of the bag, forming the spout. The upper cap (3) covers and closes the opening of the small diameter cylindrical part 23 at the tip of the middle part 2 from the front, It consists of three combinable parts.
[0015] The height of the threads (diameter of the cylinder) of the male thread of the lower part 1 and the internal thread of the middle part 2 that screws into it are set to a predetermined height that is smaller than the radial distance of the clamping space formed between the inner surface of the middle part and the outer surface of the lower part, and A transfer dispensing tool for transferring adhesive bags, characterized in that the height of the crests of at least one of the male threads of the lower part 1 or the female threads of the middle part 2 is notched at equal intervals along the circumferential direction or convex portions are formed at equal intervals, thereby partially varying the circumferential space of the "clamping space" in a certain variable pattern, thereby providing uniform small spaces in the circumferential direction of the deformed annular space, and accommodating the overlapping portion of the wrinkled bag opening.
[0016] The aforementioned "clamping space" consists of an annular space deformed into a spiral bellows shape, resulting in good clamping and sealing of the adhesive bag, making leakage less likely. Furthermore, by forming multiple notches 11C in a row, clamping and sealing is possible not only in the screw direction but also in the axial direction, and excess adhesive that spills out from the corner cut opening can be filled into the entire clamping space.
[0017] For example, in the embodiment described later, multiple notches (11C) are provided at equal intervals, with a concave shape cut out in a cross-sectional view perpendicular to the cylindrical axis, so that in the mounting state, A "clamping space" was created between the male screw of the lower part 1 and the internal screw of the middle part 2 that screws into it, by sandwiching the opening of the adhesive bag, which was created by cutting the corner of the bag.
[0018] (2) The transfer dispensing device according to claim 1, wherein the plurality of notches (11C) consist of V-shaped cuts (serrated portions) provided at equal intervals and in the same phase direction around the threads of either the middle part or the lower part, and in the plurality of threads formed along the cylindrical axis, a row of cuts parallel to the axis is formed.
[0019] By partially varying the circumferential space of the "pinching space", small spaces that are uniform in the circumferential direction of the deformed annular space are provided to accommodate the overlapping parts of the wrinkled bag. In the embodiment, 4 to 8 in the circumferential direction and arranged in 3 rows of screw threads parallel to the axial direction respectively, so that columnar small spaces in the axial direction, that is, the longitudinal direction, are formed at a plurality of circumferential positions (phases).
[0020] (3) The molded body raw material of each part is a main agent of polypropylene resin with medium to high molecular weight (400k to 600k), in addition to a fatty acid ester-based plasticizer and an internal lubricant, The pouring tool for transfer according to claim 2, characterized in that it contains a rheopectic additive.
[0021] With the appropriate blending ratio of the above-mentioned main agent PP resin and the rheopectic additive, appropriate elasticity, shape stability, and antioxidant function against the adhesive as the content are ensured so as to be able to be pressure-bonded and fixed while adhering to the bag surface of the bag opening with wrinkles formed.
[0022] In the embodiment, it consists of a blended resin of 96% by weight of polypropylene, 1% by weight of antioxidant, and 3% by weight of pigment.
[0023] (4) The pouring tool for transfer according to any one of the above, which sandwiches and attaches the bag opening formed by corner-cutting the corner part of the bag, <000For example, as shown in Figures 8 and 9 below, after opening the package, the cardboard insert is placed on top of the bag and aligned. By cutting both the bag and the cardboard insert along the cut line while they are still in this overlapping state, the bag can be cut while maintaining a flat state with appropriate cutting resistance.
[0025] (5) The adhesive bag transfer set according to claim 4, wherein the guide sheet has a double-folded structure in the area corresponding to the corner cut line CL, and at least one corner portion having the cut line CL has a right-angled triangular area with the vertical and horizontal sides of the corner portion where the cut line is made displayed in a different color or pattern from the other portion.
[0026] For example, with a bifold structure like the one shown in Figure 8, the overlapping state of the cardboard backing can be maintained by aligning the corner of the cardboard backing with the corner of the bag and partially sandwiching the bifold cardboard backing bag. [Effects of the Invention]
[0027] By employing the above-mentioned means, the present invention provides a transfer tool or transfer set that can be attached to a storage bag for adhesives that may harden or solidify during use, and can be repeatedly used without problems even after a long period of time has passed, without the cap becoming impossible to open or close, or the contents becoming impossible to dispense.

[Figure 9] An explanatory diagram showing a second guide state using the product display sheet of Example 1. [Best Mode for Carrying Out the Invention]
[0029] (basic structure) The dispensing tool for transferring adhesive according to the present invention is used by combining three parts: a "lower part" (a flanged male threaded cylinder) that is partially inserted into the corner cut portion of the adhesive bag; a middle part (a rocket screwed cylinder) that is tightened around the outer circumference of the screw of the lower part to clamp and secure the corner portion of the bag; and an upper cap that closes the opening at the tip of the middle part.
[0030] The features of this invention are as follows:
[0031] The key features are the relatively low thread height of the middle and lower parts, and the wide space between the inner and outer cylinders, which ensures a "space for inserting" the adhesive bag between the screws.
[0032] The resulting "clamping space" is a spiral space, which ensures good sealing of the adhesive bag and prevents leakage. Furthermore, since air necessary for the solidification of the adhesive bag is sealed within the clamping space, the bag opening is completely sealed and secured once it solidifies.
[0033] This prevents the adhesive from partially hardening after repeated use, which could unintentionally cause the product to detach from the bag.
[0034] The circumferential space of the "clamping space" is partially varied by providing 4 to 8 V-shaped notches at equal intervals around the threads of either or both of the middle and lower parts.
[0035] Evenly spaced small areas were created around the circumferential direction of the deformed annular space to accommodate the overlapping parts of the wrinkled bag.
[0036] The molded material for each part contains a main component of medium-to-high molecular weight (400k to 600k) polypropylene resin, a fatty acid ester-based plasticizer, an internal lubricant, and a rhopexy additive (antioxidant).
[0037] The adhesive transfer kit features a package with a bag-cutting guide, which also serves as the product display base.
[0038] A product package comprising a transfer dispensing tool that is attached by cutting the corner of the bag, and a product display card enclosed in a transparent bag, wherein the product display card has cut lines for a co-cutting guide that is used to cut together with the bag to be attached.
[0039] The bag and backing can be cut together along the cut line while they are still stacked, ensuring accurate and reliable cutting.
[0040] The guide card has a bi-fold structure with protruding pieces, and the appropriate dimensions are marked on the corners. This allows the bags to be held in place by sandwiching them between the bi-fold cardboard.
[0041] The transfer dispensing device of the present invention is The corners of the adhesive-containing bag AP are cut to form a bag opening APE, and in this attached state, the bag opening APE serves as an outlet for transferring the adhesive contents to another container, while also being resealable. The "lower part" (1), consisting of a flanged male threaded cylinder, is partially inserted into the bag opening APE, which is created by cutting the corner of the adhesive-filled bag AP, The middle part (2) consists of a cylindrical body with an internal thread, whose tip is formed by a small diameter cylindrical part 23 with an external thread, and which is tightened around the outer circumference of the screw of the lower part 1 to clamp and secure the corner of the bag, forming the spout. The upper cap (3) covers and closes the opening of the small diameter cylindrical part 23 at the tip of the middle part 2 from the front, It consists of three combinable parts, The height of the threads (diameter of the cylinder) of the male thread of the lower part 1 and the internal thread of the middle part 2 that screws into it are set to a predetermined height that is smaller than the radial distance of the clamping space formed between the inner surface of the middle part and the outer surface of the lower part, and A transfer dispensing tool for transferring adhesive bags, characterized in that the height of the crests of at least one of the male threads of the lower part 1 or the female threads of the middle part 2 is notched at equal intervals along the circumferential direction or convex portions are formed at equal intervals, thereby partially varying the circumferential space of the "clamping space" in a certain variable pattern, thereby providing uniform small spaces in the circumferential direction of the deformed annular space, and accommodating the overlapping portion of the wrinkled bag opening.
[0042] The aforementioned "clamping space" consists of an annular space deformed into a spiral bellows shape, resulting in good clamping and sealing of the adhesive bag, making leakage less likely. Furthermore, by forming multiple notches 11C in a row, clamping and sealing is possible not only in the screw direction but also in the axial direction, and excess adhesive that spills out from the corner cut opening can be filled into the entire clamping space.
[0043] For example, in the embodiment described later, multiple notches (11C) are provided at equal intervals, with a concave shape cut out in a cross-sectional view perpendicular to the cylindrical axis, so that in the mounting state, A "clamping space" was created between the male screw of the lower part 1 and the internal screw of the middle part 2 that screws into it, by sandwiching the opening of the adhesive bag, which was created by cutting the corner of the bag.
[0044] The aforementioned multiple notches (11C) consist of V-shaped cuts (serrated portions) provided at equal intervals and in the same phase direction around the threads of either the middle part or the lower part, forming rows of cuts parallel to the axis in the multiple threads formed along the cylindrical axis.
[0045] By partially varying the circumferential space of the aforementioned "clamping space," a uniform small space is created in the circumferential direction of the deformed annular space, allowing the overlapping portion of the wrinkled bag to be accommodated. In the example, four to eight screws were arranged in the circumferential direction, and each screw thread was arranged in three rows parallel to the axial direction, thereby forming small, columnar spaces in the axial direction, i.e., the vertical direction, at multiple circumferential positions (phases).
[0046] The raw materials for each part are A polypropylene resin with medium to high molecular weight (400k to 600k) is the main component, In addition to fatty acid ester-based plasticizers and internal lubricants, It is characterized by containing a leopexy additive.
[0047] By using the appropriate blending ratio of the PP resin main component and the Rheopexy additive described above, we ensured adequate elasticity that allows for close and secure adhesion to the bag surface of the wrinkled bag opening, as well as shape stability and antioxidant function for the adhesive contents.
[0048] In the example, the compound consists of 96% by weight of polypropylene, 1% by weight of antioxidant, and 3% by weight of pigment.
[0049] A transfer dispensing tool as described above, which is attached by sandwiching the bag opening created by corner cutting the corner of the adhesive bag, An adhesive transfer kit comprising a product label 4 for labeling the transfer dispensing tool as a product, enclosed in a transparent bag 5, A transfer set for adhesive bags, characterized in that the product display base 4 has a cut line CL for a guide used to cut together with the bag to be attached, indicated on it along with the numerical values of the vertical and horizontal lengths of the corners where the cut line is to be made.
[0050] For example, as shown in Figures 8 and 9, after opening the package, the cardboard insert is placed on top of the bag and aligned. By cutting both the bag and the cardboard insert along the cut line while they are still in this overlapping state, the bag can be cut while maintaining a flat state with appropriate cutting resistance.
[0051] The adhesive bag transfer set according to claim 4, wherein the guide sheet has a double-folded structure in the area corresponding to the corner cut line CL, and at least one corner portion having the cut line CL has a right-angled triangular area with the vertical and horizontal sides of the corner where the cut line is made displayed in a different color or pattern from the other portion.
[0052] For example, with a bifold structure like the one shown in Figure 8, the overlapping state of the cardboard backing can be maintained by aligning the corner of the cardboard backing with the corner of the bag and partially sandwiching the bifold cardboard backing bag.
[0053] Furthermore, the present invention is not limited to the embodiments described above and can be modified in various ways. Combinations of individual elements, extraction of some elements, disassembly into individual parts, or integrated configurations are all possible.
