Abstract

The utility model discloses a sealing cover for sealing a container, composed of an outer cover [1], a sealing ring [2], and a notch inner cover [3]. The interior of the cover top of the outer cover [1] is fixed with a permanent magnet [4]; the sealing ring [2] and the notch inner cover are connected and are embedded into the container opening; the interior of the notch is provided with a magnetic piston [5]; the side wall of the inner cover is provided with a through hole [6], and the bottom is provided with the permanent magnet [7]; the permanent magnet piston [5] in the notch is covered and disassembled along with the outer cover, and is subjected to the action of the permanent magnet [4]; when the permanent magnet piston [5] is sucked, the sealing container opens, and when the permanent magnet piston [5] falls down, the container is in the opening state. The sealing cover can conveniently and easily tightly seal and cover the container without a screw opening, having the advantages of convenient use, difficult damage and long service life; the utility model is particularly suitable for a travel cup and a travel water bottle whose covers need frequently opening.

Description

Airtight lid for container

The utility model belongs to a kind of seal cover cap that is used for container closure.

In daily life, people often will contact, use the container of shape form formula, as teacup, kettle, vacuum bottle etc., these containers of depositing potable water mostly have the lid that can open, can seal, so that keep the sanitation and hygiene of drinking-water in the container, some is used to the cup of travelling and being incubated, kettle, bottle, also require to be stamped sealing, the function of insulation, potable water is unlikely to cool off because of shaking the potable water that overflows container all of a sudden and deposit in the container.The lid of existing this class container all adopts screw socket to cover tightly, be fixed on the container, and the interface of lid and container is encased inside seal ring, and screw socket lid pinch-off seal circle just can play the effect of airtight container.Use this screw socket lid, container of every unlatching will be done a precession to the screw socket lid, the action of back-out, and when frequent spinning in and out screw socket covered, careless slightly screw thread dislocation was just easily killed lid on container; When holding boiling water in the container, screw socket is because of expanded by heating, and the unlatching of lid is just required great effort very much, particularly need often to open the container that uses, as Thermal insulation teacup, traveller's water bottle etc., the screw socket lid was both bothersome, because of frequent spinning in and out ground friction screw socket, be easy to damage the influence sealing again.

The purpose of this utility model is at the deficiency of above-mentioned screw socket lid, and a kind of fastening airtight lid for container of screw socket that need not is provided, and it can be fastened on the lid sealing on the container like a dream, can open leggiero again, uses very convenient.

For reaching above-mentioned purpose, the seal cover cap of this practical full mold is by the enclosing cover that can cover vessel port and match with it, be embedded in the seal ring in the vessel port, form with the recess inner cap that seal ring links, the caping internal fixation permanent magnet of enclosing cover, recess inner cap and seal ring link, and permanent magnet piston moving up and down is arranged in the recess, recess inner cap sidewall has through hole, makes in the recess to be interlinked to the outside.

After airtight lid for container adopts such structure, the recess inner cap embeds in the vessel port with seal ring, when enclosing cover does not cover on container, permanent magnet piston in the recess, by gravity, drop on notched bottoms, liquid in container flows into recessed cavities through the space, interval of container inner wall and recess inner cap from through hole, go out the recess inner cap, when enclosing cover covered on container, the permanent magnet that covers outward sucted the permanent magnet piston in the recessed cavities, is close on the seal ring, block the recess inner cap, though liquid in container enters in the recess from through hole, can not flow out from the recess inner cap, this container cover need not screw socket and just can make things convenient for like a cork that airtight lid for container is tight.Take off enclosing cover, the permanent magnet piston loses suction upwards in the recessed cavities, falls back at the bottom of the recess, and the recess inner cap becomes opening again.The sealing lid is suitable especially to be used on traveling glass, traveller's water bottle, also the cork bottle cap of alternative ordinary thermos bottle

The drawing explanation:

Fig. 1 is the cutaway view of the utility model use on container.

It is following that the utility model is described in further detail in conjunction with the embodiments with reference to accompanying drawing.

Airtight lid for container shown in Figure 1 is by enclosing cover [1], seal ring [2], and recess inner cap [3] is formed, and enclosing cover [1] is with the non-magnetic material injection mo(u)lding, and its shape and container match; Can cover easily on container,, and make it to be sealed in the caping interlayer at the caping fixing permanent magnet [4] of enclosing cover.Seal ring [2] is with rubber, the plastic mould pressing moulding, the section of circle becomes the T type, the size of circle and vessel port chucking match, recess inner cap [3] is with injection moulding or the moulding of aluminium punch die, one week of sidewall of inner cap has a plurality of through holes [5], the slightly outside flanging in recess upper edge, so that the seal of T type links to each other the inner cap chucking, be placed on the permanent magnet piston [6] that can move up and down in the chamber in the recessed cavities of inner cap, piston [6] is close on the seal ring [2] when upper, in at the bottom of the recess inner cap, the mid-magnetic material of injection molding process [7], when guaranteeing the container opening not tubular container become which kind of position, the permanent magnet piston is positioned at the bottom of the recess.

Claims

1, a kind of airtight lid for container that is used for container closure, form by enclosing cover [1], seal ring [2], recess inner cap [3], it is characterized in that: the caping internal fixation permanent magnet [4] of enclosing cover [1], seal ring [2] links with recess inner cap [3] and is clamped in the vessel port, the built-in permanent magnet piston moving up and down of recess [5], the sidewall of recess inner cap [3] has through hole [6].
