CN2284032Y - Thermos bottle cork with gravity valve - Google Patents

Abstract

The utility model discloses a thermos bottle stopper, comprising a stopper body and a stopper cover. A guide hole is arranged in the center of the stopper body, and the periphery of the guide hole has a drainage hole; the end surface of the stopper body has a ring surface which can cover the drainage hole by matching with the stopper cover; the bottom surface of the stopper cover is provided with a stopper rod which is penetrated between the stopper body and the guide hole and can realize on-off motions by sliding up and sliding down; the end part of the lower end of the stopper rod is provided with an end hammer which has the functions of counterweight and limitation. The stopper rod operates by the gravity function and generates inclination though the water pouring action to act function. The stopper has no direction requirement and has simple structure. The stopper has a certain benefits for reducing operation actions and improving hygiene by using the stopper on an ordinary thermos.

Description

The thermos cork of band gravity valve

The utility model relates to sealed food containers, specifically a kind of hot water thermal insulating bottle bottle stopper.

The organization plan (CN94217562.X) of a kind of flapper-type weight valve of patent documentation record.This scheme is provided with a lobe lid that is attached thereto with hinge, the action that utilizes the real reason of gravity effect that water hole is opened or closed on the hollow bottle stopper.Bottle stopper plugged and must guarantee its hinge position up when its shortcoming only was to use, could operate as normal.Otherwise it is can't use, thereby random poor.

The purpose of this utility model is to provide the thermos cork of another kind of band gravity valve, it can realize arbitrarily being provided with and keep use in the function of automatic shutter.

The thermos cork of the band gravity valve that the utility model provides, comprise cock body and gag, it is characterized in that cock body is the garden tubular, central longitudinal has the water hole more than two or two to being provided with guide hole around the guide hole, there is smooth ring face the upper end, the gag of Pei Heing is the garden sheet with it, the gag bottom surface is provided with stopper rod, and it is placed through among the guide hole of cock body, and the stopper rod rod end is end hammer shape.

The utility model has kept the characteristics that pouring need not be got plug, is carrying also and can not overflow, and sealing, heat insulation effect are identical with cork.It plugs the omnidirectional requirement of direction to bottle stopper.Water can not gone out when the selection by end hammer weight can guarantee general oblique carrying.

Be illustrated below in conjunction with embodiment and accompanying drawing thereof:

Fig. 1 is the structural representation of plug-in bottle stopper.

Fig. 2 is the structural representation of external clamping type bottle stopper.

Fig. 3 is two of an external clamping type bottle stopper version.

As shown in Figure 1, the cock body 1 and gag 5 adapteds of bottle stopper.Ring face 2 is cap seal faces, and cock body 1 is the garden tubular, and central longitudinal is provided with water hole uniform more than two or two 3 to being provided with guide hole 4 around the guide hole 4, runs through cock body up and down, guarantees that water flowing is smooth and easy.Stopper rod 6 is walked in the guide hole 4, slides up and down along guide hole 4 and realizes opening and closing, and is threaded with gag bottom center above the stopper rod, and the lower end is positioned at outside the guide hole, is end hammer shape, is used for counterweight, plays and strengthens gravity effect, the stroke limit of double as stopper rod 6.The 7th, the end hammer.

Under general angle of inclination, gag 5 covers with ring face 2 under the gravity effect of stopper rod 6 and end hammer 7, and water hole 3 is covered, and it is excessive to block water.Strengthen the angle of inclination to tying the position, gag 5 is opened under the punching press of water, and gag can reach maximum in the pouring process.Afterwards the hot water bottle is erected, the angle of inclination reduces, and gag is relied on the power playback for support under the pulling of end hammer, again the water hole cap seal on the cock body is lived, and realizes insulation.

The bottle stopper of Fig. 2 is an external clamping type, be stuck in the bead and the outer ring of hot water bottleneck, short part that water hole 3 and guide hole 4, device stopper rod 6 are set is also arranged at inner mouthful of place of cock body 1, the ring face 2 corresponding expansions of gag effect some, other structures in addition are identical with Fig. 1.

Fig. 3 has done a little to change to gag bottom face profile and corresponding cap seal face on the basis of Fig. 2 example, and other structure is all identical.

Claims (1)

1, a kind of thermos cork with gravity valve, comprise cock body (1) and gag (5), it is characterized in that cock body (1) is the garden tubular, central longitudinal is to being provided with guide hole (4), and guide hole (4) has the water hole (3) more than two or two on every side, and there is smooth ring face (2) upper end, the gag of Pei Heing (5) is the garden sheet with it, there is stopper rod (6) the gag bottom surface, and it is placed through among the guide hole (4) of cock body, and stopper rod (6) rod end is end hammer shape.
