Abstract

The utility model discloses an automatic funnel, comprising the conical body of the funnel, the mouth of the funnel and a circular cap, and the conical body of the funnel can be folded, and can be spread. The conical body of the funnel is collected to the shape of cylinder, when the utility model is not used, and the mouth of the cylinder is covered by the circular cap; while in use, the mouth of the funnel is arranged in the container, the mouth of the container is fastened by a rubber cover, and the cylinder automatically spreads in the shape of cone, after the circular cap is opened. The utility model which is convenient to store has the advantages of easy fabrication and convenient operation.

Description

Automatic funnel

The utility model is a kind of funnel, be meant especially a kind of have self-closing, open the Automatic funnel of function certainly.

The funnel cone shape size of existing funnel is all fixed, and to the container of different capabilities, need to be equipped with the funnel of different size, the depositing of funnel, carry, keeping a public place clean occupies local spended time, trouble very.

The purpose of this utility model is to provide a kind of being convenient to preserve Automatic funnel applied widely, easy to use.

The purpose of this utility model is to realize like this, funnel cone of the present utility model is to be folded into barrel-contoured film, on the circular arc between the tubular article film folding line, be bonded with the plastics hardboard, the film bottom closely is bonded together with the leakage groove that spout of funnel is connected as a single entity, the hardboard top is milled with teeth groove, and the utility model is furnished with a dome, and the dome inwall is milled with cooresponding teeth groove, when dome covers, make cylinder keep shape, after opening dome, the hardboard gravitate side direction outside, when rigid fascia film and is outwards toppled over certain angle, withstood by the leakage groove, make cylinder open the maintenance taper, when not using, hardboard has been held together, covered dome and get final product.

Advantage of the present utility model and characteristics are that funnel cone of the present utility model is one and can opens certainly, and self-closing tubular article is easy to use, carries, preserves.

Below in conjunction with a specific embodiment of the present utility model advantage of the present utility model and characteristics are described.

Fig. 1 is an exploded drawings of the present utility model.

Fig. 2 is a front elevation of the present utility model.

Fig. 3 is the folding scheme drawing of the utility model film cylinder.

Referring to Fig. 1, the utility model is by dome 1, hardboard 2, and film cylinder 3, leakage groove 4, spout of funnel 5 is formed.Fig. 2 shows the front elevation after the utility model assembling.

Film cylinder of the present utility model is that a soft plastic film is cut into circular cone is fan-shaped, it is trapezoidal 20 that film is folded into the folding face, wherein the best angle of trapezoidal hypotenuse and vertical line angle α is 30 °, two adjacent trapezoidal folding faces form a zig-zag 21, as Fig. 3, one section circular arc 22 are arranged between two adjacent sawtooth, be used for bonding hardboard 4, then it is bonded into cylindricly, the circular arc hop count is chosen on the funnel specification and is decided, as can be taken as 16 sections.

Hardboard 4 is that a width equals circular arc 22 length, length slightly is shorter than the plastic product of film drum length, is milled with teeth groove 23 of hardboard 4, is used for and 24 interlocks of dome inwall teeth groove, hardboard 4 make the back and the arc section of film cylinder bonding, form barrel of funnel of the present utility model.

On spout of funnel, also be equipped with a rubber case 6, be used for when container dress liquid, clamping bottleneck.

During use, the bottleneck that only rubber case 6 need be locked takes off dome 1, and then owing to the effect of gravity, hardboard is outwards toppled over, and the internal diameter of the convex edge 25 of leakage groove 4 just in time supports hardboard greater than outside diameter of cylinder, and it is bucket-shaped to make barrel of funnel open formation one circular cone automatically.In the time will packing up, draw cylinder in, cover dome and get final product.

Claims

A kind of Automatic funnel, form by funnel cone and spout of funnel, it is characterized in that described funnel cone is one and is folded into fan-shaped plastic sheeting cylindraceous, one section circular arc is arranged between film profile of tooth folding line, on circular arc, be bonded with hardboard, described spout of funnel has a leakage groove, wherein the leakage groove has been moulded a protrusion edge, when being used for outside hardboard, falling, support hardboard, described cylinder bottom thin film and leakage groove close adhesion, described funnel also comprises a dome, be used for holding together into when cylindric, fasten mouth cylinder when the funnel cone.
