Abstract

The utility model relates to a bottle plug, which is provided with a return mouth. The inner of the utility model is hollow, the upper part of the utility model is a small-diameter part, the lower part of the utility model is a large-diameter part, a shoulder which is a transit from the large-diameter part to the small-diameter part is provided with an inclined annular return groove (2) whose lowest point is drilled with a return hole (3) which is communicated with the inner cavity of a bottle plug (1); the circumference wall of the root part which is inserted into the bottle mouth of a bottle of the utility model is provided with accidented elastic tension surfaces (6) and (7) which make the bottle plug (1) match with a bottle whose inner diameter of the bottle mouth is slightly different from the inner diameter of the bottle plug (1) to avoid the problem that the liquid in the bottle flushes because the bottle plug matches loosely with the bottle mouth during pouring liquid.

Description

Bottle plug

The utility model belongs to the bottle that a kind of container fluid chews and chews device, mainly is to use on the oil bottle in kitchen or other seasoning matter bottle.

It is existing that to take back bottle stopper (shown in Figure 2 as Fig. 1), its root that inserts in bottleneck that stream chews be the hollow circular cylinder of light wall, and what cooperate with described root is the smooth inner wall of glass bottle opening, because the internal diameter of the bottleneck of various bottles is size slightly, so, this plug-type hollow bottle stopper is for different bottles, the elasticity of its cooperation can be mutually far short of what is expected, so that whole bottle stopper can be gone out by liquid when pouring liquid, chews disengaging with bottle.

Also having a kind of employing mode that is spirally connected to chew with bottle in existing technology keeps relatively-stationary liquid returning type bottle to chew device, as the scheme as shown in the Chinese patent CN85205104U, this bottle is chewed device and can only be matched with being with externally threaded bottle, and be exactly beer bottle and pop bottle by people as the most commonly used of oil bottle and cruet, because they are not with outside thread, so that the bottle described in the above-mentioned patent is chewed device is just not competent.

The purpose of this utility model is to overcome the shortcoming that exists in the above-mentioned prior art, release and a kind ofly can keep the close-fitting hollow bottle stopper that stream is chewed of taking back with bottle, it can or not be with externally threaded bottle adapted with the band outside thread, it can not gone out by the liquid in the bottle when toppling over, and bottle stopper can be chewed the relative fixed state that keeps good with the slightly variant bottle of various internal diameters.

Task of the present utility model is finished like this: referring to Fig. 3 and Fig. 4, can find, of the present utility model to take back its root appearance of inserting in bottleneck of hollow bottle stopper (1) that stream chews be rough elastic tension surface, this special setting in order to produce preferably tensile force when cooperating with the bottleneck inwall.There are two kinds of schemes on this elastic tension surface: scheme shown in Figure 3, be on the root periphery wall of bottle stopper (1), add annulus fin (6), it is flexible; Scheme shown in Figure 4 is the elastic tension surface (7) that processes outside protuberance on the lower, outer perimeter wall of bottle stopper (1).The whole plastics that adopt of bottle stopper (1).

Bottle stopper of the present utility model (1) has been owing to taked the measure of the tensile force between above-mentioned raising bottle stopper (1) and the bottleneck inwall, make bottle stopper (1) to the internal diameter size slightly the bottle of difference all can be suitable for, thereby overcome the shortcoming that exists in the prior art.

The utility model inserts bottle stopper (1) in the bottleneck in use, flange face (4) on the bottle stopper (1) covers bottleneck, the root on band elastic tension surface is then clamp-oned in the bottleneck tightly, being used for antisoiling cover cap (5) puts in the upside planar annular of described flange face (4), when pouring liquid, shed cover cap (5), liquid in the bottle is poured out some remaining liquid of back and can be dropped down along the outer wall of bottle stopper (1) path part, when the liquid that drops down touches bevelled backflash (2), just flow in the return port (3) of this groove nadir from top to bottom, carry over this aperture again and directly flow back in the bottle downwards.

Claims

1, a kind of bottle stopper, its body hollow, its underpart are that large-diameter portion, top are minor diameter part, on the shoulder of minor diameter part transition, have bevelled annular backflash (2) at large-diameter portion, nadir at backflash has a return port (3), it is characterized in that: on the periphery wall of one section root in its insertion bottleneck of described bottle stopper (1) rough elastic tension surface is arranged.

2, bottle stopper as claimed in claim 1 is characterized in that: described elastic tension surface is corrugated projection (7).

3, bottle stopper as claimed in claim 1 is characterized in that: described elastic tension surface is fin shape projection (6) ringwise.
