Abstract

A self-sealed lid comprises a connection lid and an outer lid arranged on top of the outside of the connection lid opening, wherein, the connection lid further comprises a pilot neck, the lower end of which is provided with a connection lid opening while the upper end of which is provided with a contraction neck connected with the connection lid opening. The capsulation of the utility model is tight and still keeps tight after the lid is opened; the utility model can reliably prevent the liquid from overflowing when the liquid is poured out.

Description

Self-sealed lid

The utility model relates to a kind of Self-sealed lid.

At present, the container of dress such as beverage bottle, medicine bottle, oil can, oil drum liquid, the structure of its container cover all in various degree have following defective or a deficiency.Vessel port is poorly sealed close, and interior dress liquid easily overflows, and after using when uncapping, sealing effectiveness is poorer.Such liquid in container is when pouring out, and liquid is easily excessive and pollute vessel port, especially charge of oil, the honey class container than thick liquid, and this phenomenon is more serious.This is not only unhygienic, and has caused waste, even vessel port can't be sealed again, uses very inconvenience.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provides a kind of sealing tight, and the back sealing effectiveness of uncapping still can keep tight, can reliably block liquid when liquid is poured out overflows, use health, convenience, vessel port is pollution-free, has the Self-sealed lid of self sealss performance.

The purpose of this utility model can reach by following measure:

A kind of Self-sealed lid, comprise connection cover 9 and be arranged at its upper end connection cover mouth 1 exterior enclosing cover 10, its special character is: described connection cover 9 also comprises guiding neck 4, the lower end of described guiding neck 4 is provided with communication port 7, and the top of described guiding neck 4 is provided with the contraction neck 3 that is communicated with connection cover mouth 1.

The bead place of above-mentioned connection cover mouth 1 can be provided with outer convex edge 2.

Blocking 6 in can being provided with in the communication port 7 of above-mentioned guiding neck 4 lower ends.

Can be provided with in the above-mentioned enclosing cover 10 and connection cover mouth 1 friction tight interior blocking 11.

Communication port 7 outsides of above-mentioned guiding neck 4 lower ends can be provided with protective cover 8.

Can be provided with between above-mentioned connection cover 9 and the enclosing cover 10 and be connected a little 5.

Above-mentioned connection cover 9 can adopt clamping, grafting or screw thread etc. to cooperate with enclosing cover 10.

The utility model compared with prior art has following advantage:

Rational in infrastructure, the vessel port sealing is tight, and interior dress liquid is difficult for overflowing.After the use of uncapping, it is tight that sealing effectiveness still can keep.When the outer convex edge that connects cover port was poured out liquid, vessel port only needed little being upturned can reliably block liquid and overflow, and uses health, convenience, and vessel port is pollution-free, is suitable for the sealing than the thick liquid vessel port especially.Connection cover, the interior blocking that covers outward make to the utlity model has multi-sealed function.Be located at the guiding neck of vessel port, especially shrink the self sealing structure of neck, when making the connection cover mouth be in opening, container is inverted, and liquid still can not flow out in it.

The accompanying drawing drawing is described as follows:

Fig. 1 is the structural representation of the utility model connection cover;

Fig. 2 is the structural representation of the utility model enclosing cover.

The drawing reference numeral explanation: 1-connection cover mouth, the outer convex edge of 2-, 3-shrinks neck, and 4-guides neck, and 5-is connected a little, blocking in the 6-, 7-communication port, 8-protective cover, 9-connection cover, blocking in the 10-enclosing cover, 11-.

The utility model is described in further detail below in conjunction with drawings and Examples:

Referring to accompanying drawing 1,2, connection cover 9 of the present utility model is threaded to one by the communication port 7 of its guiding neck 4 lower ends with vessel port, the interior blocking 6 and the vessel port flush fit that are provided with in the communication port 7.Communication port 7 outsides of guiding neck 4 lower ends can be provided with protective cover 8.The top of guiding neck 4 is the contraction necks 3 with self sealing action that are communicated with connection cover mouth 1.When contraction neck 3 made connection cover mouth 1 be in opening, container was inverted, and liquid still can not flow out in it.The bead place of connection cover mouth 1 can be provided with outer convex edge 2.Can be provided with in the enclosing cover 10 and connection cover mouth 1 friction tight interior blocking 11.Interior blocking 6,11 makes and the utlity model has multi-sealed function.Can be provided with between connection cover 9 and the enclosing cover 10 and be connected a little 5, be connected a little 5 with connection cover 9 with when enclosing cover 10 is captiveed joint, have anti-fake effect concurrently.Connection cover 9 can adopt the modes that are connected such as clamping, grafting or screw thread with enclosing cover 10.After the outer convex edge 2 at connection cover mouth 1 place is poured out liquid, only need connection cover mouth 1 little tilting upward can reliably be blocked liquid and overflowed.
