CN2124885U - Retractable cover easy to open - Google Patents

Abstract

The utility model provides a telescopic cover which is easy to open, particularly a container cover which is formed by combining a main cover body with an outer cover, wherein the outer cover is screwed on the main cover body as a seal opening, and a telescopic part is arranged on the main cover body to enable the main cover body to protrudes outward or shrink inward; the main cover body can be pressed down and inwards shrunk to be parallel to the top surface of a container at ordinary time, which is convenient to stack and place the container; the main cover body can be integrally pulled up by a pull ring of the outer cover when the utility model is in use; thus, the main cover body is protruded in the shape of a funnel in order to conveniently pour out liquid in a tank.

Description

Retractable cover easy to open

The utility model relates to a kind of telescopic easy-open end, it is combined by main lid and enclosing cover, is tied to form at ordinary times to press down shape it is flushed with container top surface, is convenient to the placement of piling up of container, pull out during use and make main lid funnel protrusion, the fluid in the jar is poured out with convenient.

Bottle cap of the prior art has many shortcomings, as shown in Figure 1, is a kind of liquid container with bottle cap, and its end face that lies in container protrudes a bottleneck A10, screws togather a bottle cap A11 again and prevents that to seal bottleneck A10 liquid from flowing out; This liquid container is because of having the bottleneck A10 of protrusion, therefore bottleneck has the effect (similar chemistry forms a taper salient with beaker at rim of a cup) of water conservancy diversion during the liquid in pouring out container, being unlikely when liquid is flowed out scatters along container top surface comes, and when having in the container of remaining liquid after opening, can lock back bottle cap A11 is again sealed, but also protrude container top surface because of bottleneck A10, make container can't pile up placement one by one, if place with the side Dumpage type, when then bottle cap A11 did not seal bottleneck A10, the liquid in the container just can run off gradually.

Again as shown in Figure 1, be a kind of liquid container,, can't seal again after opening bottle cap that then remaining liquid just is difficult for preservation in the container though its bottle cap does not protrude container top surface and makes container can pile up placement one by one with the draw-ring type bottle cap.

So design flushes with container top surface a kind of not time spent, and can protrude during use, and the bottle cap that can seal again after using is the creation motivation as the utility model.

The main purpose of the utility model is to provide a kind of telescopic easy-open end, be formed with a pars contractilis on its main lid, make easy-open end can in contract to flushing with container top surface, being convenient to container pushes away one by one to stack and puts, the easy-open end evagination that is stretched is flowed out in order to guiding liquid, and have an enclosing cover to be screwed together in easy-open end can be sealed again.

The time spent does not flush with container top surface in order to make bottle cap, can protrude during use, can seal again after the use, the utility model is to manufacture an easy-open end with soft plastic material, easy-open end system is made of main lid and enclosing cover, on main lid, be formed with a pars contractilis, pars contractilis is turned up gradually to make by its below and contracts in the easy-open end to flushing with container top surface when the easy-open end pressurized, be convenient to container one by one pile up placement, pars contractilis just turns back evagination gradually by its top when the easy-open end tension, being beneficial to guide liquid flows out, and enclosing cover system is screwed together on the main lid, can seal again so that deposit in when still remaining liq being arranged in container.

Below lift a specific embodiment, and conjunction with figs. describes the constitution content of the telescopic easy-open end of the utility model and the effect that can realize thereof in detail.

Fig. 1 is an enforcement situation of commonly using bottle cap one;

Fig. 2 is an enforcement situation of commonly using bottle cap two;

Fig. 3 is the three-dimensional exploded view of the telescopic easy-open end of the utility model;

Fig. 4 is the three-dimensional combination figure of the telescopic easy-open end of the utility model;

Fig. 5 is the enforcement situation one of the telescopic easy-open end of the utility model;

Fig. 6 is the enforcement situation two of the telescopic easy-open end of the utility model.

Referring to Fig. 3 and 4, the telescopic easy-open end of the utility model is to make with soft plastic material, comprising: main lid 10 and enclosing cover 20; Wherein, main lid 10 inner edges are formed with one and seal 11 within the sealing fully, in seal on 11 and to connect a sealing pull ring 12, when desire breaks a seal container, seal 11 in firmly pull-up sealing pull ring 12 makes and peel off main lid 10 fully, then easy-open end just has an opening, the threaded portion 13 of main lid 10 upper end outer rims for screwing togather for enclosing cover 20, by threaded portion 13 extend to downwards can make main lid 10 evaginations or in the pars contractilis 14 that contracts, extend to a flange that turns up 15 downwards by pars contractilis 14, this flange 15 is engaged in and makes main lid 10 be fixed in the end face of container on the container.

Enclosing cover 20 inner edges are provided with screw thread so that screw togather with main lid 10, seal 11 and promptly seal again after being stripped from interior with enclosing cover 20, enclosing cover 20 tops are formed with the enclosing cover draw ring 21 of a semicircle, screw togather with enclosing cover 20 and during 10 one-tenth recessed shapes of main lid, hold the enclosing cover draw ring 21 outside application of forces and main lid 10 can be pulled out into outer gibbosity in main lid 10.

Be the situation that the telescopic easy-open end of the utility model is fixed in container top surface as shown in Figure 5, this moment main lid 10 14 one-tenth states that turn up of pars contractilis, make and contract in the easy-open end and flush with container top surface, then container just can pile up placement one by one.Referring to Fig. 6, when the liquid desiring to pour out in the container, hold the enclosing cover draw ring 21 outside application of forces, then main lid 10 is drawn out into the funnel-form of evagination, outward winding enclosing cover 20 and peel off in seal 11, topple over container then 10 guidings of the liquid main lid that just can be protruded and smooth-going outflow; When still having remaining liquid to be stored in the container, enclosing cover 20 and main lid 10 screwed togather to seal again be beneficial to store.

In sum, the telescopic easy-open end of the utility model makes the liquid container with bottle cap can pile up placement one by one, and guiding liquid that again can be smooth-going flows out, and really is the product of a Nover practical.
