本発明はねじ状蓋開蓋具に関する。   The present invention relates to a screw-type lid opening device.

ねじ蓋開け具として、平面でみて、後部開口のＣ字形状に形成した弾性リング状部の開口部両端から、左右一対のレバーを後方突出した用具が知られている（特許文献１）。
特開平９−１８３４９０号公報 As a screw lid opening tool, there is known a tool in which a pair of left and right levers protrude rearward from both ends of an opening of an elastic ring-shaped portion formed in a C-shape of a rear opening in a plan view (Patent Document 1).
JP-A-9-183490

容器体ないし瓶口頸部外面へ螺合等したねじ状蓋は、締め付けが強すぎると開蓋のための蓋回動の際に指が滑り、その開蓋が困難となる。そのため上記弾性リング状部内に蓋を位置させた状態で、後方突出する左右一対のレバーを強く握って上記弾性リング状部の内径を狭め、蓋周壁を挟持させてレバーを開蓋方向へ回動させるが、従来の用具は蓋に対する、用具挟持面の位置決めが行い難い不便があった。   If the screw-shaped lid screwed into the outer surface of the container body or the neck of the bottle mouth is too tight, the finger slips when the lid is rotated for opening the lid, making it difficult to open the lid. For this reason, with the lid positioned in the elastic ring-shaped part, the pair of left and right levers protruding rearward are firmly grasped to narrow the inner diameter of the elastic ring-shaped part, and the lever is sandwiched to rotate the lever in the opening direction. However, the conventional tools have the inconvenience that it is difficult to position the tool clamping surface with respect to the lid.

本発明はその挟持面位置決めが容易であると共に、外径を異にする蓋用として、複数の挟持面を設けたものである。   In the present invention, the clamping surface is easily positioned, and a plurality of clamping surfaces are provided for a lid having a different outer diameter.

第１の手段として平面でみて、後部開口のＣ字形状に形成した弾性リング状部の両端部から左右一対のレバー４を後方突出するねじ状蓋開蓋具１において、上記リング状部２の上端部内面から複数の係合突子８を内方突設すると共にその係合突子８下方のリング状部部分内面を、下向き段部５を介して複数部分に区分して下方部分は大内径かつ上方部分は小内径のねじ状蓋挟持面に形成し、
又上記両レバーを左右後外方へ長く拡開突出させて、両レバー前部に半筒状部９を向合せて、かつ両レバー間隔を接近させたとき、それ等両半筒状部が下面開口の筒を形成可能に形成した。 As a first means, in a screw-like lid opening device 1 that projects a pair of left and right levers 4 backward from both ends of an elastic ring-shaped portion formed in a C-shape with a rear opening as viewed in plan, the ring-shaped portion 2 A plurality of engaging protrusions 8 are provided inwardly projecting from the inner surface of the upper end portion, and the inner surface of the ring-shaped portion below the engaging protrusion 8 is divided into a plurality of portions via the downward stepped portion 5 so that the lower portion is large. The inner diameter and the upper part are formed on the screw-shaped lid clamping surface with a small inner diameter,
Further, when the levers are extended and protruded to the left and right rear outwards so that the semi-cylindrical portions 9 face each other and the levers are close to each other, the two semi-cylindrical portions are A cylinder having a bottom opening was formed so as to be formed.

第２の手段として、上記第１の手段を有すると共に上記両半筒状部９内面を、両レバーの側壁内面に縦設した複数係合板12の先端面12a で形成した。   As a second means, the inner surface of both the semi-cylindrical parts 9 having the first means is formed by the front end surface 12a of the plurality of engagement plates 12 provided vertically on the inner surfaces of the side walls of both levers.

請求項１のようにすることで、弾性リング状部２内面の最上層内面に合致する外径を有する蓋開蓋の際は、該蓋上面外周部へ各係合突子８の下面を当接させて蓋の位置決めすればよく、又上記最上層内面を除く下方層内面と合致する外径の蓋開蓋の際は、その層上方に下向き段部５が形成させてあるから、その下向き段部下面を蓋上面外周へ当接させて、開蓋具の位置決めをすることが出来る。   According to the first aspect, when the lid opening having an outer diameter matching the innermost surface of the elastic ring-shaped portion 2 is applied, the lower surface of each engaging protrusion 8 is applied to the outer peripheral portion of the upper surface of the lid. What is necessary is just to position a lid | cover, and in the case of lid opening of the outer diameter which agree | coincides with the lower layer inner surface except the said uppermost layer inner surface, since the downward step part 5 is formed above the layer, it faces down The lid opening tool can be positioned by bringing the lower surface of the step portion into contact with the outer periphery of the upper surface of the lid.

請求項２の場合は、両半筒状部の内面、つまり複数係合板の各内面が蓋の外面を挟持することとなるから、該挟持時における蓋外面への接触を面接触ではなく線状の接触で行うこととなり、よって蓋に対する挟持力を強くすることが出来る。   In the case of claim 2, since the inner surfaces of both the semi-cylindrical parts, that is, the inner surfaces of the plurality of engagement plates, sandwich the outer surface of the lid, the contact with the outer surface of the lid during the clamping is not linear contact but linear Therefore, the clamping force for the lid can be increased.

以下図面について説明すると、１はねじ状蓋開蓋具である。該開蓋具は、上方からみて後部開口のＣ字形状に形成した弾性リング状部２の開口３両端部から後方（図右方）へ向けて左右一対のレバー４を後外方へ拡開突出させている。尚本願が云うねじ状蓋とは、周壁内面に雌ねじを有する通常のねじ蓋のほか、容器体口頸部の外面と蓋周壁内面との一方に溝等を、他方にはその溝内を摺動する突子等を設けて、口頸部に対する蓋の正逆両方向への回動により開閉蓋できる蓋を含むものとする。   Referring to the drawings, reference numeral 1 denotes a screw-like lid opening device. The lid opening tool expands the pair of left and right levers 4 rearward and outward from both ends of the opening 3 of the elastic ring-shaped portion 2 formed in a C-shape of the rear opening as viewed from above. It is protruding. The threaded lid referred to in the present application is a normal screw lid having a female screw on the inner surface of the peripheral wall, a groove or the like on one of the outer surface of the container neck and the inner surface of the cover peripheral wall, and the other in the groove. It includes a lid that can be opened and closed by providing a moving protrusion or the like and rotating the lid with respect to the mouth and neck in both forward and reverse directions.

図２が示すように弾性リング状部２は、上下方向中間部内面に下向き段部５を有して、該下向き段部よりも上方のリング状部分内径を小径の挟持面６に、かつ下方を大径の挟持面７とし、又リング状部２の上端内面からは複数の係合突子８をリング状部中心軸線方向へ突出させている。これ等係合突子は通常上記小径挟持面内へ嵌合させるねじ状蓋上面外周部上へ載置させるストッパーとして使用するが、それ等係合突子内端円とほぼ一致する外周を有する蓋に対しては、該蓋周壁外面へ係合突子の内端面を当接させ、該状態からレバー４を握り、各係合突子内端円を小径化させて開蓋することも可能であり、この場合のためには、各係合突子の長さを等しくし、かつ適当な厚み巾として上記挟持が可能に設けておく。   As shown in FIG. 2, the elastic ring-shaped portion 2 has a downward stepped portion 5 on the inner surface in the vertical direction, and the inner diameter of the ring-shaped portion above the downward stepped portion is formed on the small-diameter clamping surface 6 and below. Is a large-diameter clamping surface 7, and a plurality of engaging protrusions 8 project from the inner surface of the upper end of the ring-shaped portion 2 in the center-axis direction of the ring-shaped portion. These engaging protrusions are usually used as stoppers that are placed on the outer periphery of the upper surface of the screw-like lid that fits into the small-diameter clamping surface, but have an outer periphery that substantially matches the inner end circle of the engaging protrusions. The lid can be opened by bringing the inner end face of the engaging protrusion into contact with the outer surface of the peripheral wall of the cover, grasping the lever 4 from this state, and reducing the inner end circle of each engaging protrusion. In this case, the lengths of the engaging protrusions are made equal, and the above-described clamping is provided with an appropriate thickness width.

In this case, the downward stepped portions are provided at two locations, the lower end of the intermediate portion and the upper end.

図２が示すように、左右両レバー４の前部は相当の厚み巾とし、かつこれ等両レバー前部には図１、図２が示すように半円状の凹部を設けてその凹部を有頂の半筒状部９とし、これ等半筒状部を向合せに設けている。これ等両半筒状部９間を含めて両レバー間には既述開口３と連続し、かつ後方へ向かって次第に拡開する間隙10を設けており、両レバー後部を握ることでその間隙および開口３が閉じ、よって上記両半筒状部９は接して下面開口の有頂筒を形成可能としている。それ等両半筒状部９の各内面は、それぞれ蓋周壁挟持半面11を形成する。尚上記半筒状部９は有頂としたが、弾性リング状部の場合のように半筒状部上端に係合突子を、又内向きフランジを、それぞれ設けてもよく、上面開口としてもよい。   As shown in FIG. 2, the front portions of the left and right levers 4 have a considerable thickness, and the front portions of these levers are provided with semicircular recesses as shown in FIGS. A semicylindrical portion 9 is provided, and these semicylindrical portions are provided facing each other. Between these two semi-cylindrical portions 9 and between the two levers, there is provided a gap 10 which is continuous with the above-described opening 3 and gradually expands rearward. Further, the opening 3 is closed, so that both the semi-cylindrical portions 9 are in contact with each other so that a top tube with a bottom opening can be formed. The inner surfaces of both the semi-cylindrical parts 9 respectively form a cover peripheral wall sandwiching half surface 11. Although the semi-cylindrical portion 9 has a top, an engaging protrusion and an inward flange may be provided at the upper end of the semi-cylindrical portion as in the case of an elastic ring-shaped portion. Also good.

上記半筒状部９は、図６、図７が示すように半円状凹部内面へ縦設した複数の係合板12とそれ等係合板前方のリング状部２開口部分の後面２a および係合板12後方の半筒状部の後端部内面９a とで形成させてもよい。該実施形態にあっては上記複数係合板12の各先端面12a と、上記開口部分の後面２a および半円状凹部の後端部内面９a とで蓋周壁挟持面を形成することとなる。   As shown in FIGS. 6 and 7, the semi-cylindrical portion 9 includes a plurality of engagement plates 12 vertically arranged on the inner surface of the semicircular recess, the rear surface 2a of the ring-shaped portion 2 opening portion in front of the engagement plates, and the engagement plates. The rear semi-cylindrical portion 12 may be formed by the rear end portion inner surface 9a. In this embodiment, the front end surface 12a of the plurality of engagement plates 12, the rear surface 2a of the opening portion, and the rear end inner surface 9a of the semicircular recess form a cover peripheral wall clamping surface.

図示実施形態にあっては、既述大径挟持面７にだけ滑止め突条13を縦設したが、他の挟持面にも滑止め突条を従設してもよく、又図示例では各レバー４の外方側の側面へも滑止め突条14を従設している。各レバーの後端部には紐挿通孔15を穿設して、その孔に吊り掛け用のリング紐16を挿通させている。   In the illustrated embodiment, the anti-skid ridge 13 is provided vertically only on the large-diameter clamping surface 7 as described above, but an anti-skid ridge may be provided on the other clamping surface. Non-slip ridges 14 are also provided on the outer side surfaces of the levers 4. A string insertion hole 15 is formed at the rear end of each lever, and a ring string 16 for suspension is inserted through the hole.

上記開蓋具は次のように使用することが出来る。例えば小径の挟持面６内へ容器体へ嵌合させた蓋を嵌合させて該蓋上面へ係合突子８を係合させ、該状態から両レバー４を握り開口３を狭めて上記挟持筒６で蓋周壁を強く挟持し、該状態からレバー４を開蓋方向へ回し蓋を外せばよい。又レバー前部に向合せて設けた有頂の両半筒状部９内面が形成する一対の挟持半面11で蓋周壁を挟持する場合は、両半筒状部の頂板下面へ蓋上面を当接させて両挟持半面11間に蓋を位置させ、該状態から両レバー４を握って両挟持半面で蓋周壁を強く挟持させ、該状態でレバー後部を開蓋方向へ回せばよい。   The lid opening tool can be used as follows. For example, a lid fitted to the container body is fitted into the small-diameter clamping surface 6 and the engagement protrusion 8 is engaged with the upper surface of the lid, and the lever 4 is grasped from the state to narrow the opening 3 and the clamping is performed. The lid 6 may be strongly clamped by the cylinder 6 and the lever 4 may be rotated in the opening direction from this state to remove the lid. When the lid peripheral wall is sandwiched between a pair of sandwiching half surfaces 11 formed by the inner surfaces of the top half-cylindrical portions 9 provided facing the front of the lever, the top surface of the lid is applied to the bottom surface of the top plate of both half-cylindrical portions. The lid is positioned between the sandwiching half surfaces 11 and the levers 4 are gripped from the state, the cover peripheral wall is firmly sandwiched between the sandwiching half surfaces, and the lever rear portion is rotated in the opening direction in this state.

挟持用蓋外径が小径挟持面６よりも大でかつ大径挟持面７よりも小である場合は、一対のレバー間隔を弾性に抗して拡げることで小径挟持面内径を大径化させ、該大径化された小径挟持面内へ蓋を嵌合させればよい。従って各挟持面は予め定められた径よりも多少大径の蓋に対しても嵌合させることが出来る。   When the outer diameter of the clamping lid is larger than the small-diameter clamping surface 6 and smaller than the large-diameter clamping surface 7, the inner diameter of the small-diameter clamping surface is increased by expanding the distance between the pair of levers against elasticity. The lid may be fitted into the small-diameter clamping surface having the increased diameter. Therefore, each clamping surface can be fitted to a lid having a diameter slightly larger than a predetermined diameter.
