Abstract

The utility model relates to an opening device which is used for opening concave inner bottle covers, provided with a handle and the structure of working end which is positioned on the end part of the opening device, wherein, the position of the working end away from the side of the handle is provided with a pressing and supporting part which can be pressed on the upturning edge of the cover body of the concave inner bottle cover. The pressing and supporting part is connected with the handle through a connecting structure; the position of the working end closing to the side of the handle is provided with a prying and lifting structure which can be inserted in a gap between the upturning edge of the cover body and a bottle opening.

Description

Bottle cap opener in the matrix

The utility model relates to the instrument of the bottle inner plug lid that is used to open matrix.

For keeping the leak tightness of bottled article such as chemical reagent, medicine, beverage, food, also being provided with one in the bottleneck enclosing cover has bottle cap in the matrix that turns edge usually.Open difficult problem for solving this interior bottle cap, in Chinese patent 94236433.3 and 94236945.9, all once introduced the opener that is suitable for, its principle all is to utilize in working position on the instrument and the matrix friction force between the bottle cap sidewall or Clamping force to make lid break away from bottleneck, and the latter's improved type instrument has better effect.But it is comparatively complicated that its deficiency is a structure, and manufacturing cost is higher, and inconvenience is also arranged when using operation.

The purpose of this utility model be at above-mentioned situation provide a kind of structure more simple and in test confirms the desirable matrix of result of use bottle cap opener.

Have handle and the working end structure that is positioned at handle end in the matrix of the present utility model in the bottle cap opener, the support that presses down on turning edge on the bottle cap in being pressed on is arranged away from a side place of handle in this working end, and have bilateral to prop up type or be positioned at the bow type of its top, plane or the draw bail of other appropriate form makes it to link with handle; Under turning edge on the bottle cap in one side place of nearly handle is provided with and can inserts and the sled in the gap between bottleneck lift structure.Test shows, need not be by matrix inner cap sidewall be imposed application force, and the bottom that only turns edge thereon imposes the suitable sled power of lifting also can make lid break away from bottleneck smoothly.Said structure promptly adapts therewith.The support that presses down wherein can be a monolithic devices form or is interrupted the form that distributes discontinuously.For adapting to the bottle cap of different bores within the specific limits, pressing down support is good with the convex structure of stretching that is to handle orientations.Sled in the said structure is lifted structure upwards makes lid break away from the main force application part of bottleneck below the matrix inner cap turns edge, for ease of inserting the narrow gap of gripping the seam shape between below and bottleneck that turns edge on the lid, guarantee working strength and service life enough thickness requirements must be arranged except that adopting some high-intensity material directly to make the thin or ultra-thin schistose texture form, being generally.Sled can be lifted structure this moment makes to the edge and is gradually thin wedge-like structure.Lift power for ease of apply sled to turning edge on the lid, this sled lift the edge of structure or distributing position also with lid on turn edge shape near or the camber line that adapts or curve for well.

Apply the reliable validity of application force when uncapping to turning edge on the lid for further improving, above-mentioned sled lift structure on can be equipped with can with sled lift structure turn edge on forming lid the clamping shape on card structure, and can go up card and be arranged to the handle orientations heeling condition.Like this, lift structure with sled and insert gradually when turning edge on the lid, on this under card structure effect also should on turn edge that folder is tight more more.

Below the utility model foregoing is described further with example shown in the drawings.But obviously, scope of the present utility model is not only to be confined to down example.

The front elevation of a kind of structure of Fig. 1 the utility model

The A of Fig. 2 Fig. 1-A figure

Fig. 3 another version of the present utility model

Example 1

As shown in Figure 1, 2, in this matrix bottle cap opener by handle 1 be positioned at the working end that the one end is approximate hollow triangle ring type structure and constitute.Have one can be pressed on and turn edge on the bottle cap lid in the matrix on 6 and press down support 3 away from a side place of handle at this ring type structure for what stretch convex to handle orientations; It is circular-arc that one side place of the nearly handle of this ring type structure is arranged with two sections peripheries and structure 2 is lifted a little less than the sled that presses down support 3 in the plane.Can insert 6 the below of turning edge on the lid during for ease of its work smoothly, this sled is lifted structure and is adopted to be to the ring type structure inner edge and be gradually thin wedge-like shape.The middle part that sled is lifted structure side be provided with a position plane slightly high and with sled lift structure 2 turn edge on jointly can be to lid 6 one-tenths clamping shapes on card structure 4, and should on card structure 4 be to handle orientations bevelled state.The time make sled lift structure 2 accurate location and insert 6 belows that turn edge on the lid smoothly for ease of operation, prop up type draw bail 7 middle parts and be positioned at sled and lift the guide structure 5 that a convex is located respectively to be provided with in the far-end both sides of structure 2 at above-mentioned support 3 and 1 bilateral of handle of pressing down.

Example 2

Fig. 3 is the another kind of version of the utility model opener.Be in press down support 3 and handle 1 end joining draw bail 7 for be positioned at bow type structure its plane on different with last example, and the point of attachment of this bow type draw bail and handle forms the last card structure 4 that is equivalent in the example naturally, and lifting structure 2 with sled can be to the 6 formation clamping shape that turn edge on the lid.All the other structures and last example are similar, repeat no more.

Claims

1, bottle cap opener in a kind of matrix, the working end structure that handle is arranged and link with it, it is characterized in that the working end is positioned at an end of handle, be provided with to be pressed on away from the position of handle side in the working end and press down support (3) on turn edge on the bottle cap lid in the matrix (6), and have draw bail (7) that itself and handle are linked, be provided with in the position of the nearly handle side in working end can insert on the lid under turn edge (6) and between bottleneck the sled in gap lift structure (2).
