Abstract

The utility model discloses a bottle plug for a thermos flask, belonging to daily life articles. The utility model is the bottle plug which can effectively prevent that after water is poured outward, the opening of the thermos flask has dropping water when the thermos flask is erected again, comprising a bell mouth funnel, a sealing ring and a cork plug. The bell mouth funnel inserted in the opening of the thermos flask is appressed with the inner diameter of the opening of the thermos flask via the sealing ring tightly hooped out of the funnel body, and the cork plug is plugged on the bell mouth funnel. Thus, after the water is poured out from the thermos flask, the water remained in the bell mouth can automatically flow back into the thermos flask when the thermos flask is erected.

Description

Dropping-proof bottle plug for thermos flask

The utility model relates to a kind of vacuum flask bottleneck cover plug, and it belongs to daily product, is a kind of vacuum flask bottleneck cover plug that bottleneck drips can prevent effectively that vacuum flask from holding up again behind outside pouring the time.It is applicable to the ordinary thermos bottle of five pounds and eight pounds.

When vacuum flask was holded up behind outside pouring again, bottleneck had some water droplets and gets off.These water droplets on the table, first-class, can beautify the living environment to people and bring a lot of inconvenience.In order to solve this problem of dripping, prior art is to put a horn mouth plastic ring again at vacuum flask bottleneck external diameter.Like this, though solved the bottleneck problem of dripping,, the junction of horn mouth internal diameter and vacuum flask bottleneck external diameter is always assembled and is stayed some water.So very unhygienic.And because vacuum flask bottleneck external diameter and nonstandardized technique, horn mouth plastic ring internal diameter size has discrepancy just to be difficult to use slightly.Internal diameter is big, and cover is not tight, little not overlapping.At present, the vacuum flask kind is a lot of on the market, and many shells higher vacuum flask suitable for reading just can't be applied mechanically this horn mouth plastic ring.

The purpose of this utility model is exactly to provide a kind of bottleneck that can effectively prevent to drip, can prevent again the anti-dropping bottle muzzle plug of vacuum flask that bottleneck catchments.

The utility model is made up of a horn mouth funnel, a sealing ring, a chock plug.The horn mouth funnel is inserted in the vacuum flask internal diameter of the bottleneck.Bucket body external diameter is close to by the sealing ring and the vacuum flask internal diameter of the bottleneck of lock ring.When the outside pouring of vacuum flask, water outwards flows out along bucket body, horn mouth.When vacuum flask behind the pouring was holded up again, the water that remains in the horn mouth will automatically flow back in the vacuum flask along the horn mouth funnel.Because the utility model is inserted in the vacuum flask bottleneck and uses, therefore, it is not subjected to the influence of vacuum flask shell in use.Like this, with regard to both having solved the vacuum flask bottleneck problem of dripping, prevented that again bottleneck from catchmenting.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the utility model stereogram.

Fig. 2 is the utility model cutaway view.

Fig. 3 is the utility model part drawing.

With reference to Fig. 1, Fig. 2, Fig. 3.Horn mouth funnel (1) is to be made by metal or edible plastic.The one rill mouth of a river is arranged on the horn mouth, and the bucket body is a hollow Cylinder.Sealing ring (2) is the O-ring seal of being made by cork or edible rubber.Chock plug (3) is made by cork.The bucket body external diameter of horn mouth funnel (1) puts sealing ring (2).The bucket body internal diameter of horn mouth funnel (1) is plugged with chock plug (3).The bucket body of horn mouth funnel (1) puts sealing ring (2) outward, can be close to, seal with the vacuum flask internal diameter of the bottleneck.The external diameter of chock plug (3) cooperates with the bucket body internal diameter of horn mouth funnel (1).When needs pour into or pour out water, pull out chock plug (3) and get final product.

Claims

1, anti-dropping bottle muzzle plug of forming by horn mouth funnel (1), sealing ring (2), chock plug (3) of vacuum flask, it is characterized in that on the horn mouth of horn mouth funnel (1) a rill mouth of a river being arranged, the bucket body is a hollow Cylinder, the bucket body is with the sealing ring (2) that can only be close to the vacuum flask internal diameter outward, and bucket body internal diameter is plugged with a chock plug (3).

2, by the anti-dropping bottle muzzle plug of the described vacuum flask of claim 1, it is characterized in that horn mouth funnel (1) is to be made by metal or edible plastic.

3, by the anti-dropping bottle muzzle plug of the described vacuum flask of claim 1, it is characterized in that sealing ring (2) is to be made by edible plastic or cork.

4, by the anti-dropping bottle muzzle plug of the described vacuum flask of claim 1, it is characterized in that chock plug (3) is to be made by cork.
