Description

本発明は、内部に棒状の糊が充填されるスティック糊の容器に関する。 TECHNICAL FIELD The present invention relates to a glue stick container filled with stick-shaped glue.

紙等を貼着または接着するために用いられる固形の糊を細長い容器に収容し、これを少量ずつ繰り出すことのできるスティック糊が周知である。 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.

従来のスティック糊は、容器の先端に開設された円形状の糊導出口から円柱状の糊が現れるものであった。そのようなスティック糊では、例えば、四角形状の用紙の周囲に糊を塗布しようとするときに、当該用紙の縁や角の部分に糊をはみ出さないよう綺麗に塗ることが容易でない。そこで、容器の先端に開設された四角形状の糊導出口から四角柱状の糊が現れる態様のスティック糊が開発されるようになった(例えば、下記特許文献1を参照)。 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 square prism-shaped glue emerges from a square-shaped glue outlet opened at the tip of the container (see, for example, Patent Document 1 below).

スティック糊の非使用時には、容器の先端部に外側から嵌合するキャップを装着することで糊導出口を被覆する。使用者がこのキャップを脱着する際、キャップの周壁の端縁が糊を刮げるようにして糊に接触し、キャップの端部の外周に糊が付着することがあり得る。さすれば、その付着した糊の残渣が使用者の手指や用紙その他の周囲の物を汚すおそれが生じる。 When the glue stick is not used, the glue outlet is covered by attaching a cap fitted to the tip of the container from the outside. When the user attaches and detaches the cap, the edge of the peripheral wall of the cap comes into contact with the paste in such a way as to scrape off the paste, and the paste may adhere to the periphery of the end of the cap. If so, there is a risk that the adhered glue residue will stain the user's fingers, paper, and other surrounding objects.

特許第5928663号公報Japanese Patent No. 5928663

本発明は、キャップの端部の外周に付着した糊の残渣が使用者の手指や周囲の物を汚す問題の改善を図ったスティック糊の容器を提供することを所期の目的とする。 SUMMARY OF THE INVENTION An object of the present invention is to provide a glue stick container in which the problem of staining the user's fingers and surrounding objects with glue residue adhering to the periphery of the end of the cap is improved.

本発明では、内部に糊が充填される糊充填空間を有するとともに先端に前記糊を外部に導出させるための非円形状の糊導出口を有した容器本体と、この容器本体の糊充填空間が外部に連通するのを気密に遮断する閉止状態及び前記糊を外部に導出可能な開放状態の何れかを選択的にとり得る開閉機構とを具備するスティック糊の容器であって、前記開閉機構が、前記容器本体に設けられ円筒状または略円筒状をなすキャップ取付筒と、このキャップ取付筒の内側に着脱可能に嵌合する開口した端部が円筒状または略円筒状をなすキャップとを備え、前記閉止状態において装着されたキャップの端部がキャップ取付筒に外側から覆われながら当該キャップが前記糊導出口を外部から遮蔽しかつキャップの外周とキャップ取付筒の内周とが緊密に嵌合するものであり、前記キャップを覆う前記キャップ取付筒の内周面には、当該内周面から内側方に突出する円形状のリブが形成され、このリブがキャップの円筒状または略円筒状の外周面の所定部位に密接する、及び/または、前記キャップ取付筒に覆われる前記キャップの円筒状または略円筒状の外周面には、当該外周面から径方向に沿って外側方に突出する円形状のリブが形成され、このリブがキャップ取付筒の円筒状または略円筒状の内周面の所定部位に密接する、スティック糊の容器を構成した。 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 a glue filling space of the container body. A glue stick container comprising an opening/closing mechanism that can selectively assume either a closed state that airtightly blocks communication with the outside or an open state that allows the glue to be led out to the outside, wherein the opening/closing mechanism comprises: A cylindrical or substantially cylindrical cap mounting tube provided on the container body, and a cap having a cylindrical or substantially cylindrical open end detachably fitted inside the cap mounting tube, The end portion of the cap attached in the closed state is covered from the outside by the cap attachment cylinder, and the cap shields the glue outlet from the outside, and the outer circumference of the cap and the inner circumference of the cap attachment cylinder are tightly fitted. A circular rib protruding inward from the inner peripheral surface is formed on the inner peripheral surface of the cap mounting cylinder that covers the cap, and the rib is formed on the cylindrical or substantially cylindrical shape of the cap. The cylindrical or substantially cylindrical outer peripheral surface of the cap that is in close contact with a predetermined portion of the outer peripheral surface and/or is covered with the cap mounting cylinder has a circular shape protruding outward along the radial direction from the outer peripheral surface. A shaped rib is formed, and the rib is brought into close contact with a predetermined portion of the cylindrical or substantially cylindrical inner peripheral surface of the cap attachment cylinder, thereby constituting a glue stick container.

スティック糊の非使用時にキャップを容器本体に装着した閉止状態での気密性をより一層高めるためには、前記閉止状態において、前記キャップ取付筒の内側の円形状をなす嵌合部に前記キャップが嵌合するか、またはキャップの外側の円形状をなす嵌合部にキャップ取付筒が嵌合する構造とすることが好ましい。ここで、「円形状」とは、中心からの距離が一定の真円のみならず、例えば真円に近い楕円等、中心からの距離が完全に一定ではない誤差を含んだ形状をも包含する概念である。 In order to further improve the airtightness in the closed state in which the cap is attached to the container body when the glue stick is not used, the cap is attached to the circular fitting portion inside the cap attachment tube in the closed state. It is preferable to adopt a structure in which the cap mounting cylinder is fitted or fitted into a circular fitting portion on the outside of the cap. 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.

具体的な態様としては、前記キャップ取付筒にその内周面から内側方に突出する円形状のリブが前記嵌合部として形成され、または前記キャップにその外周面から外側方に突出するリブが前記嵌合部として形成されているものが想定される。 As a specific mode, the cap mounting cylinder is formed with a circular rib that protrudes inward from the inner peripheral surface thereof as the fitting portion, or the cap has a rib that protrudes outward from the outer peripheral surface thereof. It is assumed that it is formed as the fitting portion.

前記キャップ取付筒及び前記キャップがそれぞれ円筒状をなしていれば、前記嵌合部を含めた成形がより容易となる。 If the cap mounting cylinder and the cap are cylindrical, molding including the fitting portion becomes easier.

前記キャップ取付筒及び前記キャップは、例えば樹脂成形品とする。 The cap attachment tube and the cap are, for example, molded resin products.

本発明によれば、キャップの端部の外周に付着した糊の残渣が使用者の手指や周囲の物を汚す問題の改善を図ったスティック糊の容器が実現される。 According to the present invention, it is possible to realize a glue stick container that is capable of solving the problem that the glue residue adhering to the outer circumference of the end of the cap stains the user's fingers and surrounding objects.

本発明の一実施形態を、図面を参照して説明する。図1ないし図8に、本実施形態のスティック糊1及びその容器2を示す。スティック糊1は、容器2内に固形の棒状の糊3を充填または収容してなり、その糊3を容器2の糊導出口から少量ずつ繰り出して使用することのできるものである。本実施形態のスティック糊1の容器2は、内部に糊3が充填される糊充填空間41を有するとともに先端(または、前端、頂端、上端)に糊3を外部に導出させるための真円でない糊導出口42を有した容器本体4と、この容器本体4の糊充填空間41が外部に連通するのを気密に遮断する閉止状態及び糊3を外部に導出可能な開放状態を選択的にとり得る開閉機構5と、糊3を糊導出口42から漸次導出させるための糊押出機構6とを具備する。 One embodiment of the present invention will be described with reference to the drawings. 1 to 8 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 main body 4 having the glue outlet 42 and the glue filled space 41 of the container main body 4 can selectively take a closed state in which communication with the outside is blocked and an open state in which the glue 3 can be drawn out 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.

図3ないし図8に示すように、容器本体4は、糊充填空間41を内包しかつ糊充填空間41を外部に連通させる糊導出口42を先端に開設した管状体である糊充填部43と、この糊充填部43の外側を取り巻き使用者が把持するための把持部分441を有したボディ44とを備える。本実施形態では、糊充填部43とボディ44とを、例えば合成樹脂または硬質樹脂により一体成形している。但し、糊3が消費された後に新たな糊3を装填することのできる詰め替えタイプのスティック糊1にあっては、糊充填部43を交換用のリフィル(の少なくとも一部)としてボディ44に対して脱着できることがある。 As shown in FIGS. 3 to 8, the container main 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.

本実施形態における糊3は、角柱状、特に四角柱状をなす。従って、糊導出口42に至る糊充填部43の内周面431は、糊3の外周形状に合致するような角形筒状、特に四角筒状に形成してある。なお、この内周面431には、後述するレール433を突出させて設けている。糊充填部43の先端の筒状部分432は、ボディ44の先端よりも先方に突き出し、その先端に糊導出口42が開口している。 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.

ボディ44は、糊充填部43の先端筒状部分432以外の部分を抱持するもので、その外周441が糊3の外周の形状または糊充填部43の内周431の形状に相似した角筒状、特に四角筒状をなしている。換言すれば、図7及び図8に示すように、糊3及び容器2が伸長する方向と平行な軸線と直交する面で切った横断面視において、ボディ44の外側辺である四辺442が、糊充填部43及び糊導出口42の内側辺(さらには、糊3の外側辺)である四辺421と平行または略平行となっている。尤も、ボディ44の外周441の隅角部、即ち辺442と辺442とが交わる四隅は丸面取りしてある。このボディ44の外周441は、スティック糊1を使用して糊3を塗布しようとする使用者が把持することのできる把持部分として機能する。 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 and 8, 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, 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 periphery 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 .

糊充填部43及びボディ44の基端(または、後端、底端、下端)部には、糊充填空間41を基端側から閉塞する底壁45を一体成形している。底壁45の中心部には、当該底壁45を貫通する軸孔451を穿ってある。軸孔451は、後述する糊押出機構6に係わる。 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.

本実施形態のスティック糊1の容器2の開閉機構5は、容器本体4の先端側に設けたキャップ取付筒51と、このキャップ取付筒51の内側に嵌合することで装着されて容器本体4の糊導出口42を被覆するキャップ52とを要素とする。 The opening/closing mechanism 5 for the container 2 of the glue stick 1 of the present embodiment is attached to the container main body 4 by fitting a cap mounting cylinder 51 provided on the tip side of the container main body 4 to the inside of the cap mounting cylinder 51 . and a cap 52 that covers the glue outlet 42.

キャップ取付筒51は、その内周面511及び外周面514が円形状をなす、比較的厚みの薄い短尺な筒状体である。キャップ取付筒51は、空隙516を介して容器本体4の外周434を包囲しながら、径方向に沿って内方に突き出した接続部515を介して容器本体4の外周434、441に接合している。より具体的には、接続部515が、キャップ取付筒51における容器2の基端側にある部位と、ボディ44の先端または糊充填部43の先端筒状部分432の基端の近傍の部位とを連接している。本実施形態では、キャップ取付筒51とボディ44とを、例えば合成樹脂または硬質樹脂により一体成形する。同時に、キャップ取付筒51は糊充填部43(の先端筒状部分432)とも一体化しているが、既に述べたような詰め替えタイプのスティック糊1にあっては、糊充填部43とキャップ取付筒51とが分離することがあり得る。 The cap attachment tube 51 is a relatively thin and short tubular body having circular inner and outer peripheral surfaces 511 and 514 . The cap attachment cylinder 51 surrounds the outer circumference 434 of the container body 4 via a gap 516 and is joined to the outer circumferences 434 and 441 of the container body 4 via a connection portion 515 projecting inward along the radial direction. there is More specifically, the connection portion 515 is formed at a portion of the cap attachment tube 51 on the base end side of the container 2 and a portion near the base end of the tip of the body 44 or the tip 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 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.

キャップ取付筒51は、接続部515から軸線と平行または略平行に容器2の先端方向に延出しており、その内周面511が空隙516を介して容器本体4の先端筒状部分432の外周面434と対面している。つまり、キャップ取付筒51の内周511と容器本体4の先端筒状部分432の外周434との間に介在する空隙516は、容器2の先端方向に開放している。そして、キャップ取付筒51は、容器本体4の糊導出口42よりも容器2の基端側に偏倚している。即ち、糊導出口42は、キャップ取付筒51の先端よりも先方に位置する。 The cap mounting cylinder 51 extends from the connecting portion 515 in parallel or substantially parallel to the axis in the distal direction of the container 2 , and the inner peripheral surface 511 of the cap mounting cylinder 51 extends along the outer periphery of the distal end tubular portion 432 of the container main body 4 via a gap 516 . It faces the face 434 . In other words, the gap 516 interposed between the inner periphery 511 of the cap attachment tube 51 and the outer periphery 434 of the distal cylindrical portion 432 of the container body 4 opens toward the distal end of the container 2 . The cap attachment cylinder 51 is biased closer to the base end side of the container 2 than the glue outlet 42 of the container main body 4 . That is, the glue outlet 42 is located ahead of the tip of the cap attachment tube 51 .

キャップ取付筒51の基端部位は接続部515により容器本体4の外周441に連接し、その接続部515が空隙516を基端側から閉塞する。このことから、空隙516は容器2の基端方向には開放していない。キャップ取付筒51の基端は、容器本体4を把持して糊3を塗布する使用者の母指または示指の指先が触れ得る把持部分441の先端領域に臨む。 The base end portion of the cap attachment tube 51 is connected to the outer periphery 441 of the container body 4 by a connecting portion 515, and the connecting portion 515 closes the gap 516 from the base end side. Therefore, the gap 516 is not open in the proximal direction of the container 2 . The proximal end of the cap attachment tube 51 faces the distal end 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 .

キャップ52は、中空の円筒状をなす周壁521の先端側の端部を頂版524により閉塞した形状をなしており、その周壁521の外周522をキャップ取付筒51の内周511に嵌合させるようにして、キャップ取付筒51に対し着脱自在に装着することができる。キャップ52は、例えば合成樹脂または硬質樹脂により一体成形する。 The cap 52 has a hollow cylindrical peripheral wall 521 with a top plate 524 closing the tip end of the peripheral wall 521 . In this way, it can be detachably attached to the cap attachment cylinder 51 . The cap 52 is integrally formed of synthetic resin or hard resin, for example.

スティック糊1を使用しないときには、図1、図4、図6ないし図8に示すように、キャップ52の開口する基端側の端部にキャップ取付筒51を外嵌し、そのキャップ52の内に容器本体4の先端筒状部分432及び糊導出口42を収容し、当該キャップ52によりこれらを被覆して外部から遮蔽する閉止状態とする。スティック糊1を使用するときには、図2及び図3に示すように、キャップ52をキャップ取付筒51から脱離させ、容器本体4の先端筒状部分432及び糊導出口42を露出させた開放状態とすればよいことは言うまでもない。頂版524の外周縁は、若干ながら周壁521の外周よりも径方向に沿って外側方に迫り出している。 When the glue stick 1 is not used, as shown in FIGS. The tip cylindrical portion 432 of the container body 4 and the glue outlet 42 are accommodated in the container body 4 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.

キャップ取付筒51は、その内周511に、軸線方向から見て円形状の嵌合部512を有している。より具体的には、円筒状または略円筒状の内周面511の所定部位から径方向に沿って内側方に突出し周方向に沿って一周連続したリブ512を成形しており、このリブ512が嵌合部としてキャップ52の円筒状または略円筒状の外周面522の所定部位に密接することで、当該嵌合部512がキャップ52の円形状の外周522に緊密に嵌合する。リブ512の断面の外縁は、糊3及び容器2が伸長する方向と平行な軸線と重なる面で切った縦断面視において、円弧状または楕円弧状をなす。 The cap attachment cylinder 51 has a circular fitting portion 512 on its inner periphery 511 when viewed from the axial direction. More specifically, a rib 512 protruding inward along the radial direction from a predetermined portion of the cylindrical or substantially cylindrical inner peripheral surface 511 and continuing along the circumferential direction is formed. The fitting portion 512 is closely fitted to the circular outer periphery 522 of the cap 52 by closely contacting a predetermined portion of the cylindrical or substantially cylindrical outer peripheral surface 522 of the cap 52 as the fitting 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.

キャップ52もまた、その外周522に、軸線方向から見て円形状の嵌合523を有している。より具体的には、円筒状または略円筒状の外周面522の所定部位から径方向に沿って外側方に突出し周方向に沿って一周連続したリブ523を成形しており、このリブ523が嵌合部としてキャップ取付筒51の円筒状または略円筒状の内周面511の所定部位に密接することで、当該嵌合部523がキャップ取付筒51の円形状の内周511に緊密に嵌合する。リブ523の断面の外縁は、縦断面視において円弧状または楕円弧状をなす。 The cap 52 also has a circular fit 523 on its outer periphery 522 when viewed in the axial direction. More specifically, a rib 523 is formed that protrudes outward along the radial direction from a predetermined portion of the cylindrical or substantially cylindrical outer peripheral surface 522 and continues along the circumferential direction. The fitting portion 523 is closely fitted to the circular inner circumference 511 of the cap mounting cylinder 51 by closely contacting a predetermined portion of the cylindrical or substantially cylindrical inner circumferential surface 511 of the cap mounting cylinder 51 as a joint portion. do. 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.

図1、図4、図6ないし図8に示す閉止状態では、キャップ52のリブ523がキャップ取付筒51のリブ512よりも容器2の基端側に所在する。即ち、キャップ52をキャップ取付筒51に装着する過程で、キャップ52のリブ523がキャップ取付筒51に対し容器2の先端側から基端側に向かって相対的に変位し、キャップ取付筒51またはキャップ52の弾性変形を伴いながらキャップ取付筒51のリブ512を乗り越える。容器本体4の糊導出口42は、これらのリブ512、523さらにはキャップ取付筒51の先端よりも先方に配されている。 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 attachment tube 51, the rib 523 of the cap 52 is displaced relative to the cap attachment tube 51 from the distal end side to the proximal end side of the container 2, and the cap attachment tube 51 or The rib 512 of the cap attachment tube 51 is overcome while the cap 52 is elastically deformed. The glue outlet 42 of the container body 4 is arranged ahead of the ribs 512 and 523 and the tip of the cap attachment cylinder 51 .
