Description

adhesive container

The present invention relates to an adhesive container.

Adhesives for rigid polyvinyl chloride piping include organic solvents such as MEK (methyl ethyl ketone), acetone or THF (tetrahydrofuran), resins such as vinyl chloride or vinyl chloride-vinyl acetate, and stabilizers. or an organic solvent-based solution of other additives such as colorants (see Non-Patent Document 1).

The above adhesive is used when joining rigid polyvinyl chloride pipes and joints.

The container for the adhesive agent is a two-piece container including a tinplate can and a PP (polypropylene) or PE (polyethylene) lid equipped with a brush such as horsehair or nylon thread (see, for example, patent Documents 1, 2, 3). The adhesive container must ensure sufficient airtightness because the adhesive is required not to evaporate or leak during storage and transportation. Previously, a parallel top plate was provided on the can side, and a protruding sealing portion connected to the top plate was provided on the cover side.

[Problem to be solved by the invention]

The above-mentioned PP or PE caps are generally obtained by injection molding, but slight changes in molding conditions may cause uneven dimensions of the cap sealing portion.

Therefore, if a cap with uneven dimensions is used, a weak sealing part will be formed. If the ambient temperature is high when the container is placed horizontally, the organic solvent component in the adhesive may vaporize, causing leakage in the container. The internal pressure rises and the adhesive leaks.

An object of the present invention is to provide an adhesive container that can prevent adhesive leakage even when the ambient temperature is high. [Technical means to solve problems]

The adhesive container of the first invention includes a container body and a lid. An opening is formed in the container body. The cover can be installed on the container body to seal the opening. The cover has a protrusion that abuts the edge of the opening in a sealed state. The protrusion is formed in a manner to extend from the center side of the opening toward the outside toward the edge in the sealed state.

In this way, the protrusion abuts the edge in such a manner that it extends from the center side of the opening toward the outside toward the edge. This ensures sealing even if there is some unevenness in the size of the protrusion, thereby reducing the ambient temperature. In higher conditions, adhesive leakage can also be prevented.

Furthermore, contrary to the present invention, when the protrusion is formed in such a manner that it narrows from the outside of the opening to the inside toward the edge of the container body, the length of the protrusion may become longer, further inward than the edge. If it protrudes, there is a risk that air tightness cannot be ensured. In contrast, the protruding portion of the present invention is formed to extend outward, so that airtightness can be ensured without extending to the inside of the edge.

The adhesive container of the second invention is the adhesive container of the first invention, in which the protrusion is provided to extend obliquely toward the outside from the center side of the lid when not attached to the container body. Thereby, when the lid is attached to the container body, the protrusion can easily come into contact with the edge so as to extend from the center side of the opening toward the outside, thereby ensuring sealing performance.

The adhesive container of the third invention is the adhesive container of the first invention, in which the lid contains PP (polypropylene) as a main component. In this way, by including PP as the main component, it is possible to easily form a protrusion that abuts the edge so as to extend from the center side of the opening toward the outside toward the edge.

The adhesive container of the fourth invention is the adhesive container of the second invention, in which the protruding portion is deformed so as to be convexly bent toward the center side of the opening in a sealed state. In this way, by bending, the sealing performance can be further ensured, and the leakage of the adhesive can be prevented even when the ambient temperature is high.

The adhesive container of the fifth invention is the adhesive container of the first invention, in which the base end of the protrusion is located closer to the center of the lid than the front end. Thereby, when in contact with the edge, it is easy to extend from the center side of the opening toward the outside in the sealed state toward the edge. [Effects of the invention]

According to the present invention, it is possible to provide a container for adhesive that can prevent leakage of the adhesive even when the ambient temperature is high.

Hereinafter, the adhesive container according to the embodiment of the present invention will be described with reference to the drawings.

＜1.Constitution＞ (1-1. Appearance of adhesive container 1) FIG. 1 is a perspective view showing the appearance of the adhesive container 1 according to the embodiment of the present invention.

The cylindrical portion 51 is erected substantially vertically from the edge of the opening 41 a of the top plate 41 with respect to the top plate 41 . The figure shows the opening 51b at the front end of the barrel 51. The opening 51b and the opening 41a correspond to the openings at both ends of the cylindrical part 51.

A thread shape 51a is formed on the outer circumferential side surface of the barrel portion 51, and is threadedly engaged with the thread shape of the cover portion 3 described below. The figure shows the central axis O of the cylindrical part 51. Furthermore, in this specification, the term "roughly vertical" refers to the range that is considered vertical according to social conventions, and also includes design errors, etc. In addition, in this specification, the term "substantially parallel" refers to the range that is considered parallel according to social conventions, and also includes design errors, etc.

The outer peripheral portion 52 is an annular portion formed from an end (also called an upper end) of the cylindrical portion 51 toward the central axis O side of the cylindrical portion 51 . The outer peripheral portion 52 is arranged substantially parallel to the top plate 41 .

The inner peripheral portion 53 is an annular portion formed from the center side end of the outer peripheral portion 52 toward the center side of the cylindrical portion 51 . The inner peripheral portion 53 is disposed closer to the lower cover 21 (which may also be called the top plate 41 or the opening 41 a side) than the outer peripheral portion 52 . That is, the outer peripheral portion 52 and the inner peripheral portion 53 are connected with a step therebetween. The outer peripheral portion 52 and the inner peripheral portion 53 form an edge portion 55 of the opening 51b.

The inner end portion 54 is cylindrical, and is formed from the end of the inner peripheral portion 53 on the central axis O side toward the lower cover 21 . The inner end 54 is arranged substantially vertically with respect to the top plate 41 .

(1-3. Cover 3) FIG. 4 is a perspective view showing the appearance of the cover 3 .

The cover 3 is made of PP (polypropylene) resin (flexural modulus: 1000 to 2500 [MPa]), and is a PP cover with a brush. The PP cover with a brush has a horse fixed at the front end. The PP shaft 62 of the brush is made of bundled bristles, and the body part 61 has a thread shape that fits into the container body 2 . Furthermore, the material of the cover part 3 may be PE (polyethylene), nylon, etc., as long as it is a resin that is not penetrated by contents such as organic solvents and the like.

Fig. 5(a) is a partial cross-sectional view of the cover 3. The axis A represents the central axis of the lid 3 and coincides with the axis O when the lid 3 is installed on the container body 2 .

The body part 61 has a top surface 71 , side surfaces 72 , an outer cylinder part 73 , an inner cylinder part 74 , a first connecting part 75 , a second connecting part 76 and a protruding part 77 .

The top surface 71 is generally circular. The side surface 72 is cylindrical and is formed from the periphery of the top surface 71 in a direction substantially perpendicular to the top surface 71 . The outer cylinder part 73 , the inner cylinder part 74 , the first connecting part 75 , the second connecting part 76 and the protruding part 77 are arranged in the space surrounded by the top surface 71 and the side surface 72 .

The outer cylinder part 73 is cylindrical and is provided inside the side surface 72 . The outer cylinder portion 73 is provided along the side surface 72 toward the top surface 71 from the end 72 a on the opposite side to the top surface 71 of the side surface 72 . A thread shape 73a is formed on the surface of the outer cylinder part 73 on the central axis A side (which may also be called the inner surface), and can be threaded with the thread shape 51a on the outer peripheral side of the cylinder part 51.

The inner cylinder part 74 is cylindrical and is provided substantially perpendicularly to the top surface 71 from the top surface 71 toward the end 72a side. The end of the inner cylinder portion 74 on the top surface 71 side is shown as 74a, and the end on the opposite side to the end 74a is shown as 74b.

The first connecting portion 75 is annular and formed substantially parallel to the top surface 71 . The first connection part 75 connects the outer cylinder part 73 and the inner cylinder part 74 . The first connection part 75 connects the end of the outer cylinder part 73 on the top surface 71 side and the end 74a and end 74b of the inner cylinder part 74.

The PP shaft 62 is arranged closer to the central axis A side (it can also be referred to as the inner side) than the inner cylinder portion 74 . The PP shaft 62 is arranged substantially vertically relative to the top surface 71 .

The second connecting portion 76 is annular and connects the inner cylindrical portion 74 and the PP shaft 62 . The second connection portion 76 is arranged along the top surface 71 . The second connection part 76 connects the vicinity of the end 74a of the inner cylinder part 74 to the end 62a of the PP shaft 62 on the top surface 71 side.

The protruding portion 77 is annular and is provided at the end 74b of the inner cylinder portion 74 . Fig. 5(b) is an enlarged view of the S portion in Fig. 5(a) and is an enlarged view of the vicinity of the protruding portion 77.

The protruding portion 77 protrudes from the end 74b toward the end 72a side. Here, let the surface of the inner cylinder part 74 on the central axis A side (inside) be the inner side surface 74c, let the corner of the end 74b on the side of the inner side surface 74c be the inner corner 74e, and let the surface on the opposite side to the inner side surface 74c be The outer side surface 74d and the corner of the end 74b on the outer side surface 74d side are set as outer corner 74f.

The protruding portion 77 is disposed to be biased toward the inner side surface 74c of the end 74b of the inner cylinder portion 74 . Specifically, the protruding portion 77 is substantially triangular in cross-section perpendicular to the circumferential direction. The width of the protruding portion 77 becomes narrower from the end 74b side toward the protruding direction.

The inner corner 77a of the end 74b of the protrusion 77 coincides with the inner corner 74e. The outer corner 77b of the end 74b of the protrusion 77 is arranged between the inner corner 74e and the outer corner 74f. That is, the corner 77b is located further inside than the outer corner 74f. In addition, the corner 77c of the front end of the protrusion 77 is located further outside than the corner 77b (opposite to the central axis A).

In this way, the protrusion 77 is formed from the end 74b so as to extend obliquely from the inside toward the outside. In addition, the base end portion 771 of the protruding portion 77 is a portion between the corner 77a and the corner 77b, and is located further inside than the corner 77c which is the front end portion. The protrusion 77 is formed to extend outward from the central axis A side as it moves away from the end 74b.

Moreover, the corner 77c is located inward (on the central axis A side) of the outer side surface 74d of the inner cylinder portion 74. That is, the front end (corner 77c) of the protruding portion 77 is located between the thickness W of the inner cylindrical portion 74.

＜2.Function＞ Next, the function when the lid part 3 is attached to the container body 2 is demonstrated. FIG. 6(a) is a diagram showing the state when the lid part 3 is attached to the container body 2, and FIG. 6(b) is an enlarged view of the T part of FIG. 6(a).

As shown in FIG. 6(a) , the lid 3 is arranged to cover the threaded portion 42 of the container body 2 and is rotated in a predetermined direction, so that the thread shape 73a of the outer cylinder 73 of the lid 3 is in contact with the container. The thread shape 51a of the barrel portion 51 of the body 2 is threaded.

When the lid part 3 is arranged to cover the threaded part 42, or by rotating a predetermined amount, as shown in FIG. 6(a) , the corner 77c of the protruding part 77 comes into contact with the upper surface of the inner peripheral part 53 of the container body 2 53a (it can also be called the surface on the opposite side to the lower cover 21).

When the cover part 3 is rotated from this state, the cover part 3 moves to the top plate 41 side, and as shown in FIG. 7(a) , the protruding part 77 is pressed by the inner peripheral part 53. Fig. 7(a) is a diagram showing a state in which the cover 3 is closed from the state shown in Fig. 6(a), and Fig. 7(b) is an enlarged view of the V portion in Fig. 7(a).

Thereby, as shown in FIG. 7(b) , the protrusion 77 deforms so that the angle 77c approaches the end 74b of the inner cylinder 74 and is pressed against the upper surface 53a, so that the adhesive container 1 becomes a sealed state. The protrusion 77 is deformed so as to be convexly curved toward the inside (center axis O(A) side). In addition, the protruding portion 77 is arranged to extend outward from the central axis A side as it approaches the upper surface 53a.

<3.Example> Next, the adhesive container 1 of this embodiment mentioned above is demonstrated using an Example.

The air-tightness evaluation in this example was performed by placing a container containing an adhesive (ESLON Adhesive N0.73S [manufactured by Sekisui Chemical Co., Ltd.]) horizontally in an oven at 60°C for 24 hours, and then visually confirming whether there was any Leakage of adhesive (internal pressure at this time is 0.06 MPa).

(Comparative example 1) FIG. 8(a) is a diagram showing the adhesive container 100 of Comparative Example 1. Figure 8(b) is an enlarged view of the W part of Figure 8(a). The adhesive container 100 includes the container body 2 and the lid 103 described above. Compared with the cover part 3 of the above embodiment, the cover part 103 has an inner tube part 174 and a protrusion part 177 that are different from the inner tube part 74 and the protrusion part 77. The end 174b of the inner cylinder portion 174 on the opposite side to the top surface 71 is inclined from the outer surface 174d toward the inner surface 174c close to the top surface 71.

The protrusion 177 is provided at the end on the side 174d outside the end 174b. The protruding portion 177 is formed to protrude from the end 174b in a direction substantially perpendicular to the top surface 71 . The outer peripheral surface of the protrusion 177 is flush with the outer surface 174d. Furthermore, the protruding length of the protruding portion 177 protruding from the end 174b is expressed as L1.

The above-mentioned air tightness evaluation was performed using this adhesive container 100, and as a result, adhesive leakage occurred.

(Example 1) The air tightness was evaluated using the adhesive container 1 described in the above embodiment, and as a result, no adhesive leakage occurred.

(Comparative example 2) FIG. 9(a) is a diagram showing the adhesive container 200 of Comparative Example 1. Figure 9(b) is an enlarged view of the X part of Figure 9(a).

The cover 203 of the adhesive container 200 has a protrusion 277 different from the protrusion 177 compared with the cover 103 of the adhesive container 100 shown in FIG. 8(a) . The protruding portion 277 has twice the length L2 of the protruding portion 177 .

The above-mentioned air tightness evaluation was performed using this adhesive container 200, and as a result, adhesive leakage occurred.

(Comparative example 3) FIG. 10(a) is a diagram showing the adhesive container 300 of Comparative Example 3. Figure 10(b) is an enlarged view of the Y part of Figure 10(a). The adhesive container 300 includes the container body 2 and the lid 303 described above. The cover part 303 has an inner tube part 374 and a protrusion part 377 different from the inner tube part 74 and the protrusion part 77 compared with the cover part 3 of the said embodiment. The end 374b of the inner cylinder portion 374 on the opposite side to the top surface 71 is inclined from the inner side surface 374c toward the outer side surface 374d close to the top surface 71 side.

The protrusion 377 is provided at the end on the inner side 374c side. The protruding portion 377 is formed to protrude from the end 374b in a direction substantially perpendicular to the top surface 71 . The inner peripheral surface of the protrusion 377 is flush with the inner surface 374c.

The above-mentioned air tightness evaluation was performed using this adhesive container 300, and as a result, adhesive leakage occurred.

(Comparative example 4) FIG. 11(a) is a diagram showing the adhesive container 400 of Comparative Example 4. Figure 11(b) is an enlarged view of the Z portion of Figure 11(a). The adhesive container 400 includes the container body 2 and the lid 403 described above. Compared with the cover part 3 of the above embodiment, the cover part 403 has a protrusion part 477 different from the protrusion part 77. The protruding portion 477 of Comparative Example 4 is different from the protruding portion 77 of the embodiment and protrudes from the end 74b in an inclined manner from the outside to the inside.

That is, the protruding portion 477 is disposed so as to be biased toward the outer side surface 74d of the end 74b of the inner cylinder portion 74. Specifically, the protruding portion 477 is substantially triangular in cross-section perpendicular to the circumferential direction. The width of the protruding portion 477 becomes narrower from the end 74b side toward the protruding direction.

The outer corner 477b of the end 74b of the protrusion 477 coincides with the outer corner 74f. The inner corner 477a of the end 74b of the protrusion 477 is arranged between the inner corner 74e and the outer corner 74f. That is, corner 477a is located further outside than inner corner 74e. In addition, the corner 477c of the front end of the protrusion 77 is located further inside than the corner 477b. The base end portion 4771 of the protruding portion 77 is located outside the corner 477c which is the front end portion.

In this way, the protruding portion 477 is formed from the end 74b so as to extend obliquely from the outside to the inside.

The front end (corner 477c) of the protruding portion 477 is located between the thickness W of the inner cylinder portion 74. The protruding portion 477 is formed to become narrower from the outside toward the inside (center axis A side) as it moves away from the end 74b.

The above-mentioned air tightness evaluation was performed using this adhesive container 400, and as a result, adhesive leakage occurred.

＜4.Features, etc.＞ (4-1) The adhesive container 1 of this embodiment includes a container body 2 and a lid 3 . The container body 2 is formed with an opening 51b. The lid 3 can be mounted on the container body 2 to seal the opening 51b. The cover part 3 has a protrusion part 77 which abuts the edge part 55 of the opening 51b in a sealed state. The protrusion 77 is formed to extend outward from the center side of the opening 51 b toward the edge 55 in the sealed state.

In this way, the protrusion 77 contacts the edge 55 in such a manner that it extends from the center side of the opening 51 b toward the edge 55 toward the outside, thereby ensuring sealing performance even if there is some dimensional deviation in the protrusion, even at ambient temperatures. It can also prevent adhesive leakage under higher conditions.

In addition, contrary to this embodiment, if the protrusion is formed in such a manner that it becomes narrower from the outside to the inside of the opening 51b toward the edge 55 of the container body 2, the length of the protrusion will become longer than the edge. If it protrudes further inward, there is a risk that air tightness cannot be ensured. On the other hand, the protruding portion 77 in this embodiment is formed to extend outward, so that the protruding portion 77 does not protrude to the inside of the edge portion 55 and airtightness can be ensured.

(4-2) In the adhesive container 1 of this embodiment, the protrusion 77 is provided to extend obliquely toward the outside from the center side of the lid 3 when not attached to the container body 2 .

Thereby, when the lid part 3 is attached to the container body 2, the protrusion part 77 can easily come into contact with the edge part 55 so that it may extend from the center side of the opening 51b to the outside, and sealing performance can be ensured.

(4-3) In the adhesive container 1 of this embodiment, the lid part 3 contains PP (polypropylene) as a main component.

In this way, by including PP as a main component, the protrusion 77 which abuts the edge 55 so as to extend outward from the center side of the opening 51 b toward the edge 55 can be easily formed.

(4-4) In the adhesive container 1 of this embodiment, the protrusion 77 is deformed so as to be convexly bent toward the center side of the opening 51b in the sealed state.

In this way, the sealing performance can be further ensured by bending, and leakage of the adhesive can be prevented even when the ambient temperature is high.

(4-5) In the adhesive container 1 of this embodiment, the base end portion 771 of the protruding portion 77 is located closer to the center side of the lid portion 3 than the corner 77c (an example of the front end portion).

Thereby, when in contact with the edge 55 , it is easy to extend from the center side of the opening 51 b toward the outside toward the edge 55 in the sealed state.

＜Other embodiments＞ As mentioned above, one embodiment of the present invention has been described. However, the present invention is not limited to the above-described embodiment, and various changes can be made without departing from the gist of the invention.

(A) In the cover part 3 of the above-described embodiment, the corner 77c is formed at the front end of the protrusion 77. However, as shown in the protrusion 77' in Fig. 12(a), the front end 77c' may not be sharp but have a thickness.

(B) In the cover part 3 of the above embodiment, the corner 77a of the protruding part 77 coincides with the inner corner 74e, but it may not coincide with the inner corner 74e like the protruding part 77'' shown in FIG. 12(b). The protruding portion 77'' shown in FIG. 12(b) has the corner 77a'' located further outside than the inner corner 74e.

(C) In the cover part 3 of the above-mentioned embodiment, the corner 77c of the protruding part 77 is arranged between the thickness W of the inner cylinder part 74, but it may be located further outside than the thickness W (outside of the outer surface 74d).

(D) In the cover part 3 of the above embodiment, the end 74b of the inner cylinder part 74 is formed substantially parallel to the top surface 71, but it may also be inclined.

(E) In the edge portion 55 of the container body 2 of the above embodiment, a step is formed between the outer peripheral portion 52 and the inner peripheral portion 53. However, the edge portion 55 may be a flat surface without forming a step.

(F) The cover 3 in the above embodiment has the PP shaft 62, but it may not have the PP shaft 62.

(G) Although it is described that the adhesive container 1 of the above embodiment is used for storing and transporting the adhesive for rigid polyvinyl chloride pipes, it is not limited to this adhesive.
