Description

The integral type container cover

Technical field

The utility model relates to a kind of liquid containment device, particularly a kind of integral type container cover.

Background technology

The intelligent lid materials used of existing pure water barrel is many, is made up of two parts, needs more resources of production; Part fitted seal position is many, complex process, and the latent instability factor is many; Conventional seals circle processing technology difficulty is big.Need with the ring for the sealing liquid dimensional control in very little tolerance, to accomplish that this point is very difficult for the assurance sealing effectiveness, may increase reject rate simultaneously.Existing intelligent lid screw capping power is big, because it adopts side end face interference sealing, for guaranteeing that sealing effectiveness needs to cause screw capping power big the interference increasing, use inconvenient, and the power that distortion produces when variation of ambient temperature discharges nowhere, the product of producing winter is put into summer (otherwise or) and uses, and will produce cracking or defective such as poorly sealed owing to the effect of expanding with heat and contract with cold.

Summary of the invention

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide that a kind of production technology is simple, productive costs is low, screw capping power is little, easy to use and the integral type container cover of good sealing effect.

The technical scheme that its technical matters that solves the utility model adopts is:

The integral type container cover, comprise the container body, be positioned at the vessel port of container body, described vessel port is provided with screw thread, one container cover is threadedly connected on the vessel port, the central authorities of container cover are water outlet, the bottom of water outlet is provided with a water sealing slice, water sealing slice and container cover are one-body molded, water sealing slice is connected on the sidewall of water outlet by an annular flake, one end of annular flake has one and is used to keep bonded assembly thickening position, be provided with a protuberance with the relative side in thickening position on the water sealing slice, being provided with in interior week of container cover one is used for the leak free seal ring, and seal ring is provided with a bulge loop that is used to withstand the vessel port inwall.

Technique scheme also can have following improvement project: be provided with one in the bottom surface of described container cover week and be used to withstand the vessel port top and the leak free snap ring; The top of described bulge loop is provided with a bending part.

The beneficial effects of the utility model are: water sealing slice and container cover are one-body molded, and one-shot forming during production has reduced productive costs.Water sealing slice and container cover are single part, no matching relationship, and producting process difficulty reduces.The utility model both can be used as the intelligent lid of water dispenser, also can be used as the common lid use of toppling over, and practicality strengthens.Do not need very little dimension limit control, reduced system cover process difficulty, reduced reject rate, improved production efficiency.The sealing of employing bulge loop has reduced screw capping power, uses more convenient.Can not cause cracking or defective such as poorly sealed, improve the adaptive capacity to environment of product, extend the shelf life, allow product trans-regionally flow because of variation of ambient temperature produces the effect of expanding with heat and contract with cold.

The specific embodiment

Referring to figs. 1 through Fig. 6, the utility model integral type container cover, comprise container body 1, be positioned at the vessel port 2 on container body 1 top, described vessel port 2 is provided with screw thread 21, one container cover 3 is threadedly connected on the vessel port 2, the central authorities of container cover 3 are water outlet 4, the bottom of water outlet 4 is provided with a water sealing slice 5, water sealing slice 5 is one-body molded with container cover 3, water sealing slice 5 is connected on the sidewall of water outlet 4 by an annular flake 6, one end of annular flake 6 has one and is used to keep bonded assembly thickening position 7, a side relative with thickening position 7 on the water sealing slice 5 is provided with a protuberance 8, being provided with in interior week of container cover 3 one is used for leak free seal ring 9, seal ring 9 is provided with a bulge loop 91 that is used to withstand vessel port 2 inwalls, above bulge loop 91, be provided with a bending part 92, bending part 92 is as the bending point, good elasticity can be arranged, variation with compensation temperature and pressure, because elasticity is big, the requirement of tolerance on fit is so not strict, technology difficulty reduces, and the water shutoff effect is mainly finished by the sub-fraction glue position, seal point position of bulge loop 91, and the friction force during screw capping greatly reduces.

Technique scheme also can have following improvement project: be provided with one in the bottom surface of described container cover 3 week and be used to withstand vessel port 2 tops and leak free snap ring 22, after tightening lid, snap ring 22 plays the effect of auxiliary seal point, has increased the leak free safety.

The utility model will cover and be designed to integratedly with water sealing slice (with respect to traditional interior plug), reduce productive costs and technology difficulty.Lid cooperates with whorl of bottleneck, both can be used for water dispenser and also can directly turn on container cover and topple over and drink.Water sealing slice does not separate with lid after being backed down water sealing slice by water dispenser, the convenient recovery.Reduce the processing technology difficulty of container cover, because good elasticity is arranged, the container cover dimensional accuracy can reduce, and container cover and vessel port inwall area of contact reduce, and friction force reduces, and has reduced screw capping power, improves adaptive capacity to environment.Because container cover elasticity is good, can offset the expansion that produces when variation of ambient temperature.Because a side relative with thickening position 7 on the water sealing slice 5 is provided with a protuberance 8, the top roller of water dispenser pushes up protuberance 8 earlier, and the annular flake 6 around the water sealing slice 5 is torn, but because the existence at thickening position 7, thickening position 7 can not made that water sealing slice 5 continues to keep being connected not separating with container cover 3 by tear fracture, is convenient to reclaim, the water dispenser top roller moves on after backing down water sealing slice 5, until installing to the position.

In addition, the utility model is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
