Description

A kind of easy-to-draw freshness-retaining tank

Technical field

Packing box field is the utility model is related to, is specially a kind of easy-to-draw freshness-retaining tank.

Background technology

Pop can is common food package box, is uncapped for convenience, and existing tear-off tin pull ring pulling mouth position is often done recessed Fall into, but due to the difficulty of material processing, fossaperturate is not generally deep, and finger is difficult to put in, and often or can be gripped to.And The fresh-keeping multi-purpose preservative of pop can food, is not conducive to good health.

There is proposition to carry out food fresh-keeping with inert gas in recent years, nitrogen is almost inert diatomic gas, chemically Matter pole torpescence, due to the chemical inertness of nitrogen, is commonly used for protective gas, by oxygen institute oxygen during preventing that some objects are exposed to air Change, fill silo with nitrogen, grain can be made not go rotten, not germinate, it is long-term to preserve.

Utility model content

The purpose of this utility model is to provide a kind of easy-to-draw freshness-retaining tank, pass through simple structure design so that hand is easy Put in pulling mouth and pull open draw ring, while food fresh-keeping, more environmentally-friendly health are carried out with nitrogen substitution preservative.

In order to achieve the above objectives, the utility model can be realized using following technical scheme：

A kind of easy-to-draw freshness-retaining tank, including can body and lid；The can body upper end opening, sealed bottom；The lid can be close Envelope is located in the upper end opening of can body, and lid is equipped with lid side, draw ring and lid mouth, and the edge of lid edge lid is set upwards Put, surround sector, and reserve a notch, the centre of the lid is lid mouth, and the Gai Kou edges are equipped with tangent line, the lid Upper surface is equipped with draw ring close to the position of notch, and the draw ring is riveted by rivet and lid mouth, and inflating port is provided with the lid.

Preferably, the draw ring can be rotated along rivet, rotated to pulling mouth and exposed the top edge of can body, the notch side and riveting The distance between nail is more than the radius of turn of draw ring.

Preferably, inflating port is provided with the lid mouth, one way stop peturn valve is equipped with the inflating port.

Preferably, the inflating port is located at the riveting of lid mouth and draw ring.

After using the above scheme, the utility model abandons the fresh-keeping pattern of original preservative, uses nitrogen as food guarantor Gas is protected, facilitates draw ring to pull open by reserving notch on lid side, and sets inflating port to carry out nitrogen on lid and is filled with, structure Simply, it is of good preservation effect.

Fig. 3 is the utility model（It is square）Dimensional structure diagram.

In figure, 1- can bodies, 2- lids, 21- lids side, 22- notches, 23- draw rings, 24- pulling mouths, 25- rivets, 26- lids mouth, 27- inflating ports, 28- tangent lines.

Embodiment

The utility model is described in further detail with reference to embodiment, but the embodiment of the utility model is not It is limited to this.

As shown in Figure 1 to Figure 3, the preferred solution of the utility model, including can body 1 and lid 2.

Can body 1 can be that cylinder can also be square, upper end opening, sealed bottom.Four vertical ribs of square can body 1 Edge Blend angle.1 upper end opening of can body is equipped with lid 2, and the connection mode of the two is the sealed connection mode of common pop can.

Lid 2 is equipped with lid side 21, draw ring 23 and lid mouth 26, and the lid side 21 sets up along the edge of lid 2, surrounds Sector, and reserve a notch 22, the position of a fillet reserves notch to square can wherein is optimal, the centre of lid 2 For lid mouth 26,26 edge of lid mouth is equipped with tangent line 28, and upper surface is equipped with draw ring 23 close to the position of notch 22, and draw ring 23 passes through rivet 25 rivet with lid mouth 26, and for ease of opening, draw ring 23 can rotate along rivet 25, rotate to pulling mouth 24 and expose the top edge of can body 1, The distance between the position on the notch side on 22 one side of notch and rivet 25 are more than the radius of turn of draw ring 23, it is ensured that draw ring 23 rotates Shi Buhui encounters the inner side on lid side 21.23 pull-up of draw ring, tangent line 28 tear rear cover mouth 26 and leave lid 2, and this mode is common Easy open cover form.

Inflating port 27 is provided with lid mouth 26, can be enclosed for being filled with nitrogen to tank interior, after the completion of inflation on surface close Sealer, can also be equipped with one way stop peturn valve in inflating port 27, be only capable of inwardly inflating, it is ensured that internal gas will not pass through inflating port Leakage.Inflating port 27 may be provided at the riveting of draw ring 23 and lid mouth 26.

The above, is only the utility model preferred embodiment, not the technical scope of the utility model is appointed What is limited, therefore every any trickle amendment, equivalent variations made according to the technical essence of the utility model to above example With modification, the scope of protection of the utility model is still fallen within.
