Description

TECHNICAL FIELD The present invention relates to a glue stick container filled with stick-shaped glue.

2. Description of the Related Art A stick paste is well known, which is a long and narrow container containing a solid paste used for pasting or adhering paper or the like, and which can be delivered little by little.

Conventional glue sticks have a cylindrical glue coming out of a circular glue outlet opened at the tip of the container. With such a stick glue, for example, when applying glue around a square-shaped paper, it is not easy to apply the glue neatly to the edges and corners of the paper so as not to protrude. Therefore, a glue stick has been developed in which a rectangular prism-shaped glue emerges from a rectangular glue outlet opened at the tip of the container.

On the other hand, in the square pole-shaped glue stick, if the cap to be attached when not in use and the cap mounting cylinder to which the cap is fitted are each in the shape of a square cylinder, the cap and the cap mounting cylinder have a cylindrical shape. There is a disadvantage that the airtightness is lowered as compared with stick glue. The cap and the cap mounting tube, which are in the shape of a square tube, are tightly fitted together in close contact with each other at the corners, but are difficult to come into close contact with each other at the other sides, and maintain high airtightness as a whole. is difficult. If the airtightness when not in use is impaired, the glue inside the container deteriorates early, shortening the usable period, or the dried glue adheres to the inner periphery of the cap or the outer periphery of the cap mounting cylinder, causing the cap to become unusable. Problems such as hindering the attachment and detachment of the

Therefore, while the glue outlet at the tip of the container is formed into a non-circular square shape, a cylindrical cap attachment tube having a larger diameter than the glue outlet is placed outside through a gap opened toward the tip of the container. It has been devised to form a structure in which a cylindrical cap can be fitted into the cap mounting tube by forming the cap (see Patent Document 1 below).

Japanese Patent No. 5928663

SUMMARY OF THE INVENTION It is an object of the present invention to provide a glue stick container that is further improved while ensuring airtightness when the cap is attached and not in use.

In the present invention, a container body having a glue filling space in which glue is filled and a non-circular glue outlet at the tip for discharging the glue to the outside; and an opening/closing mechanism that can selectively assume either a closed state that airtightly blocks communication with the glue stick or an open state that allows the glue to be led out to the outside, wherein the opening/closing mechanism comprises the A cap-mounting tube provided on the container body and a cap detachably fitted to the cap-mounting tube from the outside, wherein the cap fits into a circular fitting portion on the outside of the cap-mounting tube, or A cap-mounting tube is fitted into a circular fitting portion inside the cap, and the cap-mounting tube has a top wall connected to the container body at the tip thereof, and at least a part of the inner peripheral surface. is opposed to the container main body through a gap opened in the base end direction opposite to the tip end.

Here, the term "circular shape" includes not only a perfect circle with a constant distance from the center, but also an ellipse that is close to a perfect circle, and a shape with an error whose distance from the center is not completely constant. It is a concept.

The cap attachment tube may extend from the top wall in the proximal direction to the tip region of the grip portion that can be touched by the tip of the thumb or index finger of the user who performs the operation of applying the glue on the container body. be. In this case, the extending end of the cap attachment tube and the tip end region of the gripping portion are separated from each other through the opening of the gap, and the outer side of the gripping portion is the inner side of the glue outlet in a cross-sectional view. The shape may be parallel or substantially parallel to the sides.

Alternatively, the cap attachment cylinder extends from the top wall in the proximal direction to the base end region of the container body, and the thumb and forefinger of a user who performs the operation of applying the paste to the cap attachment cylinder. It is also possible to adopt a mode in which the finger-to-toe portion between the can be touched. In this case, the cap attachment cylinder may have a cylindrical outer periphery.

It is also conceivable to form a shape in which the outer diameter of the cap mounting cylinder gradually decreases in the distal direction and the inner diameter of the cap gradually decreases in the same direction.

One embodiment of the present invention will be described with reference to the drawings. 1 to 9 show a glue stick 1 and its container 2 of this embodiment. The glue stick 1 is formed by filling or containing a solid stick-shaped glue 3 in a container 2, and the glue 3 can be fed little by little from a glue outlet of the container 2 for use. The container 2 of the glue stick 1 of this embodiment has a glue filling space 41 in which the glue 3 is filled, and the tip (or the front end, the top end, or the upper end) of the container 2 does not have a perfect circle for leading out the glue 3 to the outside. The container body 4 having the glue outlet 42 and the glue filling space 41 of the container body 4 can selectively take a closed state that airtightly blocks communication with the outside and an open state that allows the glue 3 to be discharged to the outside. An opening/closing mechanism 5 and a glue push-out mechanism 6 for gradually drawing out the glue 3 from the glue outlet 42 are provided.

As shown in FIGS. 3 to 9, the container body 4 includes a glue filling portion 43, which is a tubular body having a glue outlet 42 at its tip that encloses a glue filling space 41 and communicates the glue filling space 41 with the outside. , and a body 44 surrounding the outside of the glue filling portion 43 and having a grip portion 441 for a user to grip. In this embodiment, the glue filling portion 43 and the body 44 are integrally formed of synthetic resin or hard resin, for example. However, in the case of a refill type glue stick 1 in which new glue 3 can be loaded after the glue 3 is consumed, the glue filling section 43 is used as (at least a part of) a replacement refill for the body 44. You can put it on and take it off.

The paste 3 in this embodiment has a prism shape, particularly a quadrangular prism shape. Accordingly, the inner peripheral surface 431 of the glue filling portion 43 reaching the glue outlet 42 is formed in a square tube shape, particularly a square tube shape, so as to match the outer peripheral shape of the glue 3 . A rail 433, which will be described later, protrudes from the inner peripheral surface 431. As shown in FIG. A cylindrical portion 432 at the tip of the glue filling portion 43 protrudes further than the tip of the body 44, and the glue outlet 42 is opened at the tip.

The body 44 holds the portion other than the tip cylindrical portion 432 of the glue filling portion 43, and its outer circumference 441 is a rectangular tube whose outer circumference 441 is similar to the shape of the outer circumference of the glue 3 or the shape of the inner circumference 431 of the glue filling portion 43. shape, especially a square cylinder. In other words, as shown in FIGS. 7 to 9, in a cross-sectional view taken along a plane perpendicular to the axis parallel to the direction in which the glue 3 and the container 2 extend, the four sides 442, which are the outer sides of the body 44, are It is parallel or substantially parallel to the four sides 421 that are the inner sides of the glue filling portion 43 and the glue outlet 42 (and the outer sides of the glue 3). Of course, the corners of the outer circumference 441 of the body 44, that is, the four corners where the sides 442 intersect are chamfered. The outer periphery 441 of the body 44 functions as a gripping portion that can be gripped by the user who intends to apply the glue 3 using the glue stick 1 .

A bottom wall 45 that closes the glue filling space 41 from the base end side is formed integrally with the base end (or rear end, bottom end, or lower end) of the glue filling portion 43 and the body 44 . A shaft hole 451 penetrating through the bottom wall 45 is drilled in the center of the bottom wall 45 . The shaft hole 451 is related to the glue pushing mechanism 6 which will be described later.

The opening and closing mechanism 5 for the container 2 of the glue stick 1 of this embodiment is attached to the container body 4 by fitting the cap mounting cylinder 51 provided on the tip side of the container body 4 and the cap mounting cylinder 51 from the outside. and a cap 52 that covers the glue outlet 42.

The cap attachment tube 51 is a relatively thin and short tubular body having circular outer peripheral surfaces 511 and 514 . The cap mounting cylinder 51 surrounds the outer periphery 441 of the container body 4 with a gap 516 interposed therebetween, and is joined to the outer periphery 441 of the container body 4 via a top wall 515 projecting inward along the radial direction. More specifically, the top wall 515 separates a portion of the cap attachment cylinder 51 on the distal end side of the container 2 and a portion near the distal end of the body 44 or the proximal end of the distal cylindrical portion 432 of the glue filling portion 43 . are connected. In this embodiment, the cap attachment tube 51 and the body 44 are integrally formed of synthetic resin or hard resin, for example. At the same time, the cap attachment tube 51 is also integrated with (the tip cylindrical portion 432 of) the glue filling section 43, but in the refill type glue stick 1 as already described, the glue filling section 43 and the cap attachment tube are integrated. 51 may be separated.

The cap attachment cylinder 51 and the top wall 515 are biased toward the base end side of the container 2 with respect to the glue outlet 42 of the container body 4 . That is, the glue outlet 42 is located ahead of the base and the top wall 515 of the cap attachment tube 51 .

The cap mounting cylinder 51 extends from the top wall 515 in parallel or substantially parallel to the axis in the base end direction of the container 2 , and the inner peripheral surface 517 of the cap mounting cylinder 51 extends through the gap 516 to the outer peripheral surface 441 of the body 44 of the container main body 4 . I'm facing The base end opposite to the top wall 515 of the cap attachment cylinder 51 faces the tip region of the grip portion 441 that can be touched by the tip of the thumb or index finger of the user who grips the container body 4 and applies the paste 3 . The extending end of the cap attachment tube 51 and the tip region of the grip portion 441 are separated from each other through the opening of the gap 516 . In other words, the gap 516 interposed between the inner periphery 517 of the cap attachment tube 51 and the outer periphery 441 of the body 44 of the container main body 4 is open in the base end direction of the container 2 .

On the other hand, the base of the cap attachment tube 51 is connected to the outer periphery 441 of the container body 4 by the top wall 515, and the top wall 515 closes the gap 516 from the tip side. not open. The width of the gap 516 along the radial direction, in other words, the distance along the radial direction between the inner circumference 517 of the cap mounting cylinder 51 and the outer circumference 441 of the body 44 is the distance between the base of the cap mounting cylinder 51 joined to the top wall 515 . gradually expands toward the extending end of the cap mounting cylinder 51 facing the grip portion 441 .

As shown in FIGS. 7 to 9, the inner circumference 517 of the cap mounting cylinder 51 is inscribed in the four corners of the outer circumference 441 of the body 44 of the container body 4 and integrated with the body 44 at these four corners. is becoming Therefore, the gap 516 is separated by the four corners of the body 44 .

The cap 52 has a hollow cylindrical peripheral wall 521 whose distal end is closed by a top plate 524 . , can be detachably attached to the cap attachment tube 51 . The cap 52 is integrally formed of synthetic resin or hard resin, for example.

When the glue stick 1 is not used, as shown in FIGS. 1, 4, 6 to 8, the cap 52 is fitted onto the cap mounting tube 51, and the cylindrical end of the container body 4 is inserted into the cap 52. The part 432 and the glue outlet 42 are accommodated and covered with the cap 52 to form a closed state in which they are shielded from the outside. When using the glue stick 1, as shown in FIGS. 2 and 3, the cap 52 is detached from the cap mounting tube 51, and the tip cylindrical portion 432 of the container body 4 and the glue outlet 42 are exposed. It goes without saying that The outer peripheral edge of the top plate 524 slightly protrudes outward from the outer periphery of the peripheral wall 521 along the radial direction.

The cap attachment cylinder 51 has a circular fitting portion 512 on its outer circumference 511 when viewed from the axial direction. More specifically, a rib 512 that protrudes outward along the radial direction from a predetermined portion of the cylindrical or substantially cylindrical outer peripheral surface 511 and is continuous along the circumferential direction is formed. The fitting portion 512 is closely fitted to the circular inner periphery 522 of the cap 52 by closely contacting a predetermined portion of the cylindrical or substantially cylindrical inner peripheral surface 522 of the cap 52 as a joint portion. The outer edge of the cross section of the rib 512 forms an arc shape or an elliptical arc shape in a longitudinal cross-sectional view taken along a plane overlapping an axis parallel to the direction in which the paste 3 and the container 2 extend.

The cap 52 also has a circular fitting 523 on its inner periphery 522 when viewed from the axial direction. More specifically, a rib 523 protruding inward along the radial direction from a predetermined portion of the cylindrical or substantially cylindrical inner peripheral surface 522 and continuing along the circumferential direction is formed. The fitting portion 523 is closely fitted to the circular outer circumference 511 of the cap mounting cylinder 51 by closely contacting a predetermined portion of the cylindrical or substantially cylindrical outer peripheral surface 511 of the cap mounting cylinder 51 as the fitting portion. . The outer edge of the cross section of the rib 523 has an arc shape or an elliptical arc shape when viewed in vertical cross section.

In the closed state shown in FIGS. 1, 4, 6 to 8, the rib 523 of the cap 52 is positioned closer to the proximal end of the container 2 than the rib 512 of the cap mounting cylinder 51 is. That is, in the process of attaching the cap 52 to the cap mounting cylinder 51, the rib 523 of the cap 52 is relatively displaced from the distal end side of the container 2 to the proximal end side with respect to the cap mounting cylinder 51, and the cap mounting cylinder 51 is displaced. It gets over the rib 512 of the cap attachment tube 51 while being elastically deformed. The glue outlet 42 of the container body 4 is arranged ahead of these ribs 512 and 523 and the base of the cap attachment tube 51 .

An outer circumference 511 of the portion extending from the base portion of the cap mounting cylinder 51 toward the extended end is cut from the tip side so as to make the portion thinner than the other portions. This notch 510 is continuous along the circumferential direction. In the closed state with the cap 52 attached, the edge of the peripheral wall 521 of the cap 52 is accommodated in the notch 510 . Then, the end surface 525 of the peripheral wall 521 of the cap 52 abuts or comes very close to the end surface 513 of the notch 510 facing the tip direction of the container 2 . The rib 523 of the cap 52 bulges from a position facing the inner peripheral surface 522 of the edge portion of the cap 52 and the outer peripheral surface 511 of the notch 510 formed in the cap mounting cylinder 51 . The rib 512 of the cap attachment tube 51 bulges from a position facing the outer peripheral surface 511 of the notch 510 of the cap attachment tube 51 and the inner peripheral surface 522 of the edge portion of the cap 52 . In the closed state, the outer circumference 526 of the peripheral wall 521 of the cap 52 and the outer circumference 514 of the portion of the cap mounting cylinder 51 closer to the base end of the container 2 than the notch 510 are flush or substantially flush. Incidentally, the thickness of the portion of the cap attachment cylinder 51 closer to the base end than the notch 510 tends to decrease toward the base end of the container 2 .

As shown in FIGS. 3 to 5, the glue pushing mechanism 6 includes a threaded rod 61 inserted through a shaft hole 451 of the bottom wall 45 of the container body 4 and entering the glue filling space 41 in the glue filling portion 43, It has a manually operated knob 62 fixed to the proximal end of a threaded rod 61 outside the glue filling section 43 separated by a wall 45 and an elevator 63 screwed onto the threaded rod 61 within the glue filling section 43. ing. The outer circumference 621 of the knob 62 has a rectangular tubular shape, particularly a square tubular shape, matching the shape of the outer circumference 441 of the body 44 of the container main body 4 that serves as the grip portion. A male thread 611 is cut on the outer periphery of the threaded rod 61 .

The elevator 63 has a bottomed box shape that opens toward the tip of the container 2 and supports the glue 3 filled in the glue filling space 41 in the glue filling section 43 . A female threaded hole 631 is provided in the center of the bottom of the elevator 63 to engage the male thread 611 of the threaded rod 61 . The outer peripheral surface 632 of the elevator 63 is formed in a square tubular shape, particularly a square tubular shape, so as to match the shape of the inner peripheral surface 431 of the glue filling portion 43 . In this way, one of the inner peripheral surface 431 of the glue filling portion 43 and the outer peripheral surface 632 of the elevator 63 that abuts or is very close to it is provided along the extension direction of the glue 3 and the container 2, that is, the advance and retreat direction of the glue 3. A rail 433 extending in the same direction is provided so as to protrude, and a concave groove 633 extending in the same direction and engaging with the rail 433 is provided on the other side. The concave-convex engagement between the rail 433 and the groove 633 prevents the elevator 63 from rotating about the axis relative to the container body 4 , while preventing the elevator 63 from rotating relative to the container body 4 about the axis. It guides you to move in parallel.

In order to feed the glue 3 from the glue outlet 42 and use it, the user removes the cap 52 to expose the glue outlet 42, and then moves the knob 62 on the outside of the container body 4 to the axis line. It should be rotated in the forward direction. As a result, the screw shaft rotates in the forward direction together with the knob 62, and the elevator 63 screwed therewith moves toward the tip end approaching the glue outlet 42 in the glue filling portion 43 of the container body 4. The supported glue 3 is extruded from the glue filling space 41 through the glue outlet 42 .

In order to make the glue 3 that has been fed out after use go deeper than the glue outlet 42, the user should rotate the knob 62 in the opposite direction around the axis. Then, the screw shaft rotates in the reverse direction, the elevator 63 moves in the direction of the proximal end away from the glue outlet 42 in the glue filling section 43 , and the glue 3 supported by the elevator 63 is pulled into the glue filling space 41 . be After that, the cap 52 is put on again to cover the glue outlet 42 to be in a closed state.

In this embodiment, a container body 4 having a glue filling space 41 in which the glue 3 is filled and a non-circular glue outlet 42 at the tip for discharging the glue 3 to the outside, and the container body 4 and an opening/closing mechanism 5 that can selectively take either a closed state that airtightly blocks communication of the glue filling space 41 of 4 with the outside or an open state that allows the glue 3 to be led out to the outside. In the container 2, the opening/closing mechanism 5 includes a cap mounting cylinder 51 provided on the container body 4 and a cap 52 detachably fitted to the cap mounting cylinder 51 from the outside. The cap 52 is fitted to the circular fitting portion 512 on the outside of the cap 52, or the cap mounting cylinder 51 is fitted to the circular fitting portion 523 on the inside of the cap 52. It has a top wall 515 connected to the container main body 4 at its distal end, and at least a part of the inner peripheral surface 517 is connected to the container main body 4 through a gap 516 opened in the proximal direction opposite to the distal end. A container 2 for the glue stick 1, which faces each other, is constructed.

With such a configuration, it is possible to draw out the prism-shaped paste 3 from the square-shaped paste outlet 42 and apply the paste 3 to the corners of a rectangular sheet of paper without difficulty and beautifully. The tip cylindrical portion 432 of the glue filling portion 43 and the glue outlet 42 are located ahead of the base portion and the top wall 515 of the cap attachment tube 51, and the visibility is good, and the place to apply the glue 3 can be easily determined. You can always work while checking.

When the glue stick 1 is not used, the cap 52 is fitted to the outer circumference 511 of the cap mounting cylinder 51 and attached so that the glue 3 filled in the glue filling space 41 of the glue filling portion 43 is sealed, so that the glue 3 is dried. It is possible to prevent or suppress deterioration of the quality and performance of the paste 3 over time due to other causes. In particular, since the fitting portion 512 of the cap mounting cylinder 51 and the fitting portion 523 of the cap 52 are formed in a perfect circle or a nearly perfect circle, as shown in FIGS. It is possible to uniformly bring the cap mounting cylinder 51 into close contact with the cap mounting cylinder 51 over the entire circumference, thereby avoiding the problem that airtightness is impaired due to the occurrence of a gap in a part.

A gap 516 is provided between the inner peripheral surface 517 of the cap attachment tube 51 and the outer peripheral surface 441 of the container body 4 to make the thickness of the cap attachment tube 51 uniform along the circumferential direction and to precisely fit the fitting portion 512 . can be a perfect circular shape. Thereby, the airtightness in the closed state with the cap 52 attached is enhanced. In addition, since the gap 516 is provided, the cap mounting cylinder 51 is more likely to be elastically deformed in the radial direction. ), the cap 52 can be smoothly attached/detached or opened/closed.

According to this embodiment, the base of the cap attachment tube 51 and the container body 4 are joined via the top wall 515 , and the gap 516 between the cap attachment tube 51 and the container body 4 extends in the base end direction of the container 2 . It opens, but does not open in the distal direction and is closed. Therefore, in the closed state in which the cap 52 is fitted onto the cap mounting tube 51, the interior of the cap 52 accommodating the tip cylindrical portion 432 of the container body 4 and the glue outlet 42 and the gap 516 do not communicate with each other. isolated. Therefore, the air in the gap 516 does not come into contact with the glue 3 in the closed state. can be effectively suppressed.

The cap 52 covers the cap mounting cylinder 51 from the front end side, and the presence of the top wall 515 improves the strength of the cap mounting cylinder 51 to which the cap 52 is fitted, thereby enhancing the airtightness in the closed state. Even if an external force is applied unexpectedly, the risk of the cap 52 detaching from the cap mounting cylinder 51 is reduced.

In general, while maintaining the airtightness of the cap 52 in the closed state, the degree of freedom of the shape of the glue outlet 42 can be increased, and the problem of drying and other deterioration of the glue 3 can be solved, and the edge of the paper can be It is possible to improve the workability of applying the glue 3 to the corner portions.

In addition, in the present embodiment, the cap attachment tube 51 is positioned so that the tip of the thumb or index finger of the user who performs the operation of applying the glue 3 on the container body 4 touches in the proximal direction from the top wall 515 . Extends to the distal region of the gripping portion 441 to obtain. As a result, the user can naturally hold the container body 4 by putting his/her finger on the extended end of the cap attachment tube 51, and the stick 1 is difficult to remove and easy to use.

When a member such as a grip made of rubber, soft resin, or the like is attached to the outer periphery 441 of the gripping portion of the container body 4, the member is engaged with the gap 516 opening toward the base end of the container 2. It can be used as an engaging portion.

Further, the extending end of the cap mounting cylinder 51 and the tip end region of the gripping portion 441 are separated from each other through the opening of the gap 516, and the outer edge 442 of the gripping portion 441 is the above-mentioned Since it is parallel or substantially parallel to the inner side 421 of the glue outlet 42, the direction of the side of the glue 3 fed out from the glue outlet 42 by the user is the direction of the edge of the paper to which the glue 3 is to be applied. The operation of aligning them in parallel becomes easy.

The present invention is not limited to the embodiments detailed above. In the above embodiment, the cap attachment tube 51 extending from the position of the top wall 515 toward the base end of the container 2 is relatively short. , the base end of which can reach the vicinity of the base end of the container body 4 or just in front of the knob 62 of the glue pushing mechanism 6 .

10 to 13, the cap attachment tube 51 extends from the top wall 515 to the base end region of the container body 4 in parallel or substantially parallel to the axis. That is, the cap attachment tube 51 surrounds substantially the entire body 44 from the outside. Therefore, the outer periphery 518 of the cap attachment cylinder 51 functions as a gripping portion that can be gripped by the user who intends to apply the glue 3 using the glue stick 1 . Unlike the above-described embodiment, in this modified example, the grip portion 518, that is, the outer circumference of the cap attachment tube 51 and the outer circumference 621 of the knob 62 of the glue pushing mechanism 6 are cylindrical.

On the other hand, the inner peripheral surface 517 of the cap attachment tube 51 faces the outer peripheral surface 441 of the body 44 of the container body 4 through the gap 516, and the inner peripheral surface 517 of the cap attachment tube 51 faces the outer peripheral surface 441 of the body 44. It is the same as the above embodiment in that the four corners are inscribed and integrated, and the gap 516 is divided by the four corners of the body 44 . The extending end of the cap attachment tube 51 and the base end region of the body 44 are separated from each other through the opening of the gap 516 . That is, the gap 516 in the container body 4 is open in the base end direction of the container 2 . Of course, the opening of the gap 516 is shielded by a knob 62 that expands radially so that its outer circumference 621 is flush or substantially flush with the outer circumference 518 of the cap mounting cylinder 51, and is not exposed to the user. I don't understand.

The base of the cap attachment tube 51 is connected to the outer periphery 441 of the container body 4 by the top wall 515, and the top wall 515 closes the gap 516 from the tip side, so that the gap 516 is open in the tip direction of the container 2. not. The width of the gap 516 along the radial direction, in other words, the distance along the radial direction between the inner periphery 517 of the cap attachment tube 51 and the outer periphery 441 of the body 44 is constant or substantially constant.

In this modification, the cap attachment tube 51 and the gap 516 extend from the top wall 515 in the proximal direction to the proximal region of the container body 4 . That is, since the cap mounting tube 51 and the gap 516 exist over substantially the entire length of the container body 4 excluding the tip cylindrical portion 432 , the glue 3 filled in the glue filling space 41 in the glue filling portion 43 is heat insulation effect can be obtained, and the change over time caused by the temperature change of the glue 3 can be suppressed. Moreover, the integrally extended cap attachment cylinder 51 can be touched by the inter-finger portion between the thumb and forefinger of the user who performs the operation of applying the glue 3, so that the user can use this as the grip portion 518 to firmly hold the cap attachment cylinder 51. can be grasped.

In addition, in the above-described embodiment and modified example, the peripheral walls 521 of the cap attachment cylinder 51 and the cap 52 extend parallel or substantially parallel to the axis along the direction in which the glue 3 and the container 2 extend, so to speak, straight. However, as shown in FIG. 14, the cap mounting cylinder 51 is tapered such that the outer diameter gradually decreases from the base end side to the tip end side, and the cap 52 The peripheral wall 521 may be shaped like a truncated cone or a funnel whose inner diameter gradually expands accordingly.

Furthermore, in the above-described embodiment and modified example, the base portion of the cap attachment tube 51 did not protrude beyond the top surface of the top wall 515, but as shown in FIG. It may be extended from 515 in the direction of the tip of the container 2 , and the tip may protrude beyond the top surface of the top wall 515 . However, the glue outlet 42 is located ahead of the cap attachment cylinder 51 . An outer periphery 519 of the cap attachment cylinder 51 that protrudes forward beyond the top wall 515 can be used as a fitting portion 512 that is in close contact with the inner periphery of the peripheral wall 521 of the cap 52 . For example, a rib 512 that bulges outward along the radial direction is formed on the outer periphery 519 of the relevant portion of the cap mounting cylinder 51 , and this rib is used as the fitting portion 512 to be in close contact with the inner periphery 522 of the peripheral wall 521 of the cap 52 . Let Alternatively, a rib 523 that bulges inward along the radial direction is formed on the inner circumference 522 of the peripheral wall 521 of the cap 52 , and the rib is used as the fitting portion 523 to closely contact the outer circumference 519 of the relevant portion of the cap mounting cylinder 51 . You can also let
