Abstract

An exhaust rubber plug for a crisper is characterized by comprising a top button, a sealing cover and a support cover. The middle of the end surface of the sealing cover extends outwards to form the top button. Between the top button and the end surface of the sealing cover, the end surface of the sealing cover inwardly concaves to form a circle of separation grooves surrounding the bottom of the top button. The lower end surface of the sealing cover extends outwards to form the support cover which is arranged at the lower end of the sealing cover. A blind hole is disposed in the middle of the support cover, and the blind hole is large in radius of the upper end and small in radius of the lower end. The exhaust rubber plug for the crisper can effectively prolong freshness retaining time of food in the crisper and strengthen freshness retaining effect of the crisper, and is strong in applicability.

Description

Crisper is used the exhaust plug

Technical field

The utility model relates to a kind of exhaust plug, and particularly a kind of crisper is used the exhaust plug.

Background technology

Crisper is not only convenient and practical, and can food be deposited categorizedly.It can prevent that moisture from distributing, and air-isolation prevents that food is oxidized, can prevent that food from losing original delicate flavour when storing, play the leak free effect.Existing crisper kind is abundant, and its function is also various, but the still fresh-keeping effect as described above of its basic function.

In when storage, in that food is placed on box body and the leak free process, aeroseal that in fact also will part is in the inside; After the placement long the time; Box body still can breed bacteria, makes food spoilage, mainly just is the device that the crisper neither one can exhaust.

Summary of the invention

The purpose of the utility model provides a kind of crisper to use the exhaust plug in order to address the above problem exactly.

The utility model the technical scheme that will deal with problems following:

A kind of crisper is used the exhaust plug, it is characterized in that: comprise top button, capping and support lid; Said top button forms by extending laterally in the middle of the capping end face, and capping end face indent forms the separate slot of corral button bottom around the top between top button and capping end face; Said support lid is positioned at the capping lower end and is extended laterally by the capping lower surface and form, and in the middle of the support lid, is provided with a little blind hole of upper end radius big lower end radius.

Said support lid is by the support lid main body that evenly is provided with breach and cover the support of body rim between breach and breach in support and cover the support sheet that main body extends laterally and form; The cooresponding place of said capping lower surface and breach is provided with gas guide groove.

This reality has later-model beneficial effect following:

Compared with prior art, adopt a kind of crisper of the utility model structure to use the exhaust plug, can the crisper that air is arranged be carried out exhaust; With the set gas guide groove in the cooresponding place of breach, the extrusion of button through the top impels air to be discharged by gas guide groove from the breach sucking-off below capping; Easy to use, effect is obvious, has prolonged food fresh keeping time in crisper; Strengthen the fresh-keeping effect of crisper, had stronger practicality.

Description of drawings:

Fig. 1 is the utility model crisper structural representation Fig. 1 with the exhaust plug;

Fig. 2 is the utility model crisper structural representation Fig. 2 with the exhaust plug;

Fig. 3 is the generalized section of the utility model crisper with the exhaust plug.

Among the figure: 1, top button; 2, capping;

21, separate slot; 22, blind hole;

23, gas guide groove; 3, support lid;

31, breach.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is done further detailed elaboration.

Consult Fig. 1, Fig. 2, Fig. 3, said crisper is used the exhaust plug, comprises top button (1), capping (2) and support lid (3); Said top button (1) forms by extending laterally in the middle of capping (2) end face, and capping (2) end face indent forms the separate slot (21) of corral button (1) bottom around the top between top button (1) and capping (2) end face; Said support lid (3) is positioned at capping (2) lower end and is extended laterally by capping (2) lower surface and form, and in the middle of support lid (3), is provided with a little blind hole (22) of upper end radius big lower end radius.

Said support lid (3) is by support lid (3) main body that evenly is provided with breach (31) and be positioned at support between breach (31) and the breach (31) in support lid (3) body rim and cover the support sheet (32) that (3) main body extends laterally and form; Said capping (2) lower surface and the cooresponding place of breach (31) are provided with gas guide groove (23).

During use; The exhaust plug is installed to above the crisper lid that has pore, lid is covered on box body, at first facing to top button (1) extruding downwards; Form the separate slot (21) of corral button (1) bottom around the top because of capping (2) end face indent between top button (1) and capping (2) end face; Capping (2) can not purse up to the inside, is provided with a upper end little blind hole (22) of the big lower end of radius radius in the middle of support lid this moment (3) because top button (1) makes expansion of blind hole (22) aperture and hole shorten downwards, when the power on being pressed in top button (1) is unclamped; Blind hole (22) restores to the original state; In this process, the air pressure that produces when the air in the box body is recovered by blind hole (22) picks up, and air does not flow out from the breach (31) of support lid (3) main body because of blind hole (22) does not communicate with the external world; In the gas guide groove (23) of windstream to capping (2) lower surface; When all recovered when the exhaust plug, these air went round and began again and just can reach the purpose to the crisper exhaust outside just the gas guide groove (23) of top button (1) lower end is discharged to outside being positioned at crisper.

Claims (1)

1. a crisper is used the exhaust plug, it is characterized in that: comprise top button, capping and support lid; Said top button forms by extending laterally in the middle of the capping end face, and capping end face indent forms the separate slot of corral button bottom around the top between top button and capping end face; Said support lid is positioned at the capping lower end and is extended laterally by the capping lower surface and form, and in the middle of the support lid, is provided with a little blind hole of upper end radius big lower end radius; Said support lid is by the support lid main body that evenly is provided with breach and cover the support of body rim between breach and breach in support and cover the support sheet that main body extends laterally and form; The cooresponding place of said capping lower surface and breach is provided with gas guide groove.
