Abstract

The utility model relates to an easy-break safety bottle cap, comprising an upper cap (1), and a lower cap (2). The upper cap and the lower cap are integrated into one unit. The top face of the lower cap is provided with two arc-shaped slot seams which are separated a small section to connect. The other end of the two slot seams starts with nick to extend to the cylinder face of the lower cap along the top face. The edge of the upper cap is provided with a convex flange (11) which is held by a hand to tear the upper cap, and then the bottle cap is torn from the slot beams along the nick, so the bottle cap is opened. The easy-break safety bottle top avoids the disadvantage of the prior art that a bottle cap can not be opened because a structure that a bottle jack is circumferentially torn is easy to break at a midway. The utility model is convenient use.

Description

Easy-break safety bottle top

The utility model relates to a kind of bottle cap, more specifically, relates to a kind of bottle cap of easily breaking into two with one's hands.

Its lid of bottle of present numerous powder charge water, health beverages has a circle undercut line at the enclosing cover of packing seal overcoat jewelling on the enclosing cover round edge, the origin or beginning of this line of rabbet joint is the head that floats, and holds this head when uncapping and tears, and just can the crossheading line be torn by lid.

But problem of such lid ubiquity: usually fracture midway in the process of tearing, just be not difficult to uncap son by other instrument this moment.This makes the user very inconvenient, and therefore the drink of existing a large amount of outlets is returned goods.

The purpose of this utility model provides a kind of Bottle cap structure of easily breaking into two with one's hands, has not only easily drawn back but also tear fracture midway not.

Solution of the present utility model is as follows:

Bottle cap is made up of loam cake and lower cover, and lower cover is a hat-shaped configuration, has summit portion and face of cylinder part integrally formed, and its cylindrical part is for being engaged on the leak free bottleneck; Its end face central porose has on the diameter greater than this hole seat to have circular arc-shaped slits, and there is the segment part that links to each other line of rabbet joint middle part, thereby about the line of rabbet joint forms totally two; Dividing other to hold in addition from the line of rabbet joint has indentation along the diad Y-Y that is parallel between above-mentioned two lines of rabbet joint, and this two indentation turns to continuation to extend axially along it along the lower cover face of cylinder after arriving described top edge; Described loam cake is plain film shape or the cap-like structure that is buckled on the described hd top face down, outstanding bead is arranged on its edge, loam cake has convex towards the middle body of this one side of lower cover, this convex has identical size and the shape in hole with following hd top face central authorities, link closely in the hole of described lower cover, and make the Y-Y axis of loam cake bead diad and above-mentioned lower cover consistent, and make the bead and the line of rabbet joint be in same one side of something.

Above-mentioned two lines of rabbet joint preferably occupy circumference half together with continuous part therebetween.

Described loam cake is preferably by rigid plastic, and for example polypropylene or low pressure polyethylene are made.Groove or dovetail slot can be established in the face of cylinder of described convex, and this convex can be firmly secured in the medium pore of lower cover with pressure sintering upper and lower cover is combined into one.

Described lower cover is metallic material preferably, and for example the duralumin material is made.

Bottle cap of the present utility model is because broad and weak point between two indentations, and larger slot seam guiding is arranged, and tensile phenomenon midway can not occur, and is easy to use, errorless.

Fig. 1 is the bottle cap section-drawing of an embodiment of the utility model.

Fig. 2 is the upward view of loam cake among Fig. 1.

Fig. 3 is the birds-eye view of lower cover among Fig. 1.

Fig. 4 is the figure of the another embodiment of lower cover.

Fig. 5 is the section-drawing of Fig. 4 lower cover.

Fig. 6 is position, a lower cover edge indentation place partial schematic diagram.

Below with reference to accompanying drawing embodiment of the present utility model is described.

Fig. 1 is the section-drawing of an embodiment bottle cap.Wherein 1 is loam cake, and 2 is lower cover.Fig. 2 is the loam cake upward view of Fig. 1.Fig. 3 is the lower cover birds-eye view of Fig. 1.From the visible lower cover of Fig. 1 is hat-shaped structure, and an end face and a face of cylinder 25 are arranged, and this face of cylinder 25 supplies and the interlock of bottleneck (not shown).From the visible loam cake of Fig. 2 also is hat-shaped structure, be enclosed within down and cover, 11 is bead outstanding on the loam cake outer rim, and 12 be the convex given prominence to towards the one side of lower cover of heart part therein, its face of cylinder is established recessed dovetail slot 13(and is seen Fig. 1 on one week), loam cake is made by polypropylene.Fig. 3 central authorities are the hole 22 of hd top face under the break-through, and there are above-mentioned convex 12 identical shaped and sizes in this hole, supply convex 12 is pressed on wherein phase embedding mortise, or are moulded mortise with hot pressing.21 for being in hole 22 is concentric but than the line of rabbet joint of two described end faces of break-through on the circumference of long radius, continuous part 23, two lines of rabbet joint 21 and continuous part 23 that 21 of two lines of rabbet joint have segment not open account for circumference together half.From two lines of rabbet joint divide other in addition end diad Y-Y of being parallel to two lines of rabbet joint indentation 24 through lower cover edges are arranged and turn to the face of cylinder 25 of lower cover to continue suitable lower cover and extend axially.The cooperation of upper and lower cover should make the diad of loam cake bead 11 consistent with lower cover line of rabbet joint diad Y-Y, and makes the bead 11 and the line of rabbet joint 21 be in same one side of something.

Such bottle cap is as long as hand bead 11 tearings, and the part that at first links to each other 23 disconnects, and tears and uncover along indentation 24 then.

In another improved embodiment, the hole 26 that covers down is one and removes the shape (see figure 4) that crescent moon part back forms from circular port, this crescent moon partly is to be intercepted mutually and get with circumference by string perpendicular to the Y-Y axis in close another semicircle of the circular not sum line of rabbet joint 21 in hole 22, correspondingly, the convex of loam cake also with hole 26 shapes and consistent size.The change in described hole 26 helps the arrangement of work flow.

In order to increase rigidity, can establish a circle projection 27(on the following hd top face and see Fig. 5).Safety when this projection can play this lid can of protection does not make indentation disconnect.

In also having an embodiment, the hole that covers is a polygon down, for example pentagon or hexagon.

The cap-like structure that changes loam cake 1 in another embodiment is the plain film structure, and promptly loam cake is a sheet structure that is attached to down on the hd top face, and bead 11 is outwards outstanding.

In an improved embodiment again, indentation arrives the position at top edge place on the following hd top face, and this edge is processed to fillet as shown in Figure 6, and the benefit of doing like this is when indentation is torn more smooth in this corner.

Above embodiment is for example, and the utility model protection domain that is defined by the claims is not limited in this example.
