Abstract
The utility model discloses a plastic extensible bottle cap which comprises a hollow cap body (1) and a sealing cap body (2), the hollow cap body is composed of a top portion (11), a folded portion (12) and a bottom portion (13), the top portion, the folded portion and the bottom portion are sequentially connected from top to bottom, the diameter of the top portion is smaller than that of the bottom portion, the top portion is connected with the sealing cap body through external threads, the bottom portion is provided with internal threads, foldable flexible extensible pieces are sequentially connected from top to bottom to form the folded portion, the width of the middle of each extensible piece is larger than that of the upper end of each extensible piece and that of the lower end of each extensible piece, the middle of each extensible piece is provided with a horizontal fold (12a), the widths of the extensible pieces which form the folded portion gradually become smaller from bottom to top, extensible pieces in the upper layer are placed inside extensible pieces in the lower layer respectively after the extensible pieces are folded, and all the extensible pieces are placed in an inner cavity of the bottom portion. Due to good elasticity and flexibility of thin-wall plastic, the stretched bottle cap can be bent and can play a role of a duct and a hopper, the contracted bottle cap can seal liquid in a bottle body, and no extra space is occupied.
Description
Technical field
The utility model relates to a kind of flexible bottle cap of plastics that can regulate length, is used for being installed in the oral area of container, can shrink downwards or upwards stretching.
Background technology
In daily life, when the liquid in the container being poured in another container, especially need the liquid in the heavy caliber container is poured in the small-caliber vessel, reveal when avoiding liquid to pour into, need be by means of funnel; When there is obstacle the container that is introduced into top, need connect two vessel port by means of conduit, topple over again after perhaps container or obstacle being moved, very inconvenience operates.
The utility model content
The utility model aims to provide a kind of retractable plastic bottle closure, during use, can upwards stretch, and has the effect of conduit and funnel concurrently, after using, can shrink downwards, does not take redundant space, carries, uses all very convenient.
For this reason, the technical scheme that the utility model adopts is: a kind of plastics bottle cap that stretches, comprise hollow cap (1) and seal cover cap (2), described hollow cap (1) is by the top (11) that links to each other successively from top to bottom, folding part (12) and bottom (13) constitute, and top (11) diameter is less than bottom (13) diameter, described top (11) links to each other with seal cover cap (2) by outside thread, bottom (13) has negative thread, folding flexibleness stretching sheet constitutes by linking to each other also from top to bottom successively in described folding part (12), the middle part width of each stretchable sheet is greater than the width at two ends up and down, and the middle part of each stretchable sheet is provided with a horizontal creases (12a); The stretchable sheet that constitutes folding part (12) diminishes from top to bottom gradually, make stretchable sheet folding after, the upper strata stretchable sheet is positioned at the inboard of lower floor's stretchable sheet, and all stretchable sheets are arranged in the inner chamber of bottom (13).
During use, hollow cap and seal cover cap be by being threaded, and hollow cap and body are by being threaded, and seal cover cap should be to prevent that liquid from flowing out through hollow cap on hollow cap; In the time liquid need being poured into the less container of bore from the container that flexible bottle cap is housed, when there is obstacle the top that perhaps is introduced into container, then the folding part of the bottle cap that stretches upwards can be drawn into extended configuration, open the seal cover cap of flexible bottle cap again and topple over; When needs are poured out liquid fast from the container that flexible bottle cap is housed, directly turn on hollow cap and topple over; Topple over finish after, press the folding part downwards, used stretchable sheet is folded again, screwing hermetic lid gets final product again.
Further, the wall thickness of above-mentioned stretchable sheet after stretchable sheet is folding, to inner ring depression downwards gradually, makes top (11) and seal cover cap (2) be arranged in the inner chamber of bottom (13) together by the outer ring less than the wall thickness of bottom (13).Utilize elasticity and the elasticity of thin-walled plastic, make stretchable sheet only need very little power just can realize folding, fold up very light; Stretchable sheet after folding by the outer ring to inner ring downward depression gradually, be to make staff clamp seal cover cap easily with the seal cover cap spinning in and out in order to vacate enough spaces on the one hand, be in order to guarantee that top and seal cover cap can not reach the hollow cap outside on the other hand, further guarantee overall dimensions and the packing measurements of bottle cap, thereby can not influence the vanning cost.
Beneficial effect: because elasticity and the elasticity of thin-walled plastic itself are better, make the bottle cap after the stretching can be crooked, played the effect of conduit and funnel, the bottle cap that shrinks can seal the liquid in the body, and do not take redundant space, design ingenious, applied range, easy to carry, convenient and swift during use.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As Fig. 1---the bottle cap that stretches of the plastics shown in 4, formed by hollow cap 1, seal cover cap 2 two parts, both are Plastic Parts.Hollow cap 1 is made of the top 11, folding part 12 and the bottom 13 that link to each other successively from top to bottom, has the fluid passage of up/down perforation in the hollow cap 1, is hollow structure.Top 11 diameters of hollow cap 1 can be retracted in the inner chamber of bottom 13 to guarantee top 11 less than bottom 13 diameters.Top 11 links to each other with seal cover cap 2 by outside thread, and bottom 13 has negative thread, is used for being connected with body.Folding part 12 is by linking to each other successively from top to bottom and folding flexibleness stretching sheet constitutes, and the middle part width of each stretchable sheet is greater than the width at two ends up and down, and the middle part of each stretchable sheet is provided with a horizontal creases 12a.The stretchable sheet that constitutes folding part 12 diminishes from top to bottom gradually, and after guaranteeing that stretchable sheet is folding, the upper strata stretchable sheet is positioned at the inboard of lower floor's stretchable sheet, and all stretchable sheets are arranged in the inner chamber of bottom 13.
The wall thickness of stretchable sheet with elasticity and the elasticity of utilizing thin-walled plastic, makes stretchable sheet only need very little power just can realize folding less than the wall thickness of bottom 13.In conjunction with Fig. 3, Fig. 4 as can be known, after stretchable sheet is folding, by the outer ring to inner ring depression downwards gradually, make top 11 and seal cover cap 2 be arranged in the inner chamber of bottom 13 together, both can vacate enough spaces makes staff clamp seal cover cap easily with the seal cover cap spinning in and out, can guarantee that again top 11 and seal cover cap 2 can not reach hollow cap 1 outside, have further guaranteed overall dimensions and the packing measurements of bottle cap, thereby can not influence the vanning cost.
As shown in Figure 1, the top of stretchable sheet and the angle of bottom are α, by adjusting the size of α, can adjust the length after stretch the folding part, and bending direction and angle of bend.In conjunction with Fig. 5, Fig. 6 as can be known, directly over second container 5 obstacle is arranged, the liquid in first container 4 can't directly be poured in second container 5.Yet, because the flexible bottle cap of plastics described in the utility model is housed on first container 4, open seal cover cap 2 earlier, the folding part 12 of the flexible bottle cap of stretched plastic again, and make it crooked, top 11 is placed the oral area of second container 5, first container 4 that tilts at last, but just avoiding obstacles is poured the liquid in first container 4 in second container 5 into.Topple over finish after, press folding part 12 downwards, used stretchable sheet is folded again, screwing hermetic lid 2 gets final product again.
