Description

A kind of milk powder box

Technical field

The utility model relates to a kind of container, particularly a kind of milk powder box.

Background technology

Milk powder box is to be used for a kind of container of splendid attire milk powder, because milk powder is easy to the conglomeration of making moist, and it is trickle powder shape, flies away leakage easily, so the seal request of milk powder box is higher.Usually, the structure of milk powder box comprises lid and box body, realizes sealing through between lid and box body, embedding seal ring then.Because the existence of seal ring has been arranged, after lid and box body pressing, thereby its inside can be hedged off from the outer world basically and forms the fully enclosed space, so even in box splendid attire milk powder, the inclination box can not cause leakage yet.

But the milk powder box on the market is simple in structure in order to pursue mostly now, cost-cutting, and make that the positional structure that supplies seal ring to install is not firm, and often seal ring comes off easily, and gets loose easily after lid and the box body pressing, and sealing effectiveness is undesirable.Simultaneously, its size is single, is not sufficient to satisfy the demand of various capacity.

The utility model content

The purpose of the utility model is for a kind of milk powder box is provided.

The solution that the utility model solves its technical matters is:

A kind of milk powder box; Comprise box body and with the lid of box body top opening pressing; It is downward first inwall and second inwall that the peripheral from-inner-to-outer of said lid is provided with direction of extension; Slit between said first inwall and second inwall constitutes ring cavity, is embedded with seal ring in the said ring cavity, and the upper limb of said box body imbeds in the sealing circle.

As the further improvement of technique scheme, the inside face of the outer wall of the upper limb of said box body and second inwall is fitted.

As the further improvement of technique scheme, the outer wall of said box body top is provided with the buckle ear, and the edge of said lid is provided with the buckle earclip closes and breaks button off with the fingers and thumb.

As the further improvement of technique scheme, the downward bending of said buckle ear, said break off with the fingers and thumb to buckle be provided with the bending end that can embed the buckle ear and the flange in the space between the box body outer wall.

As the further improvement of technique scheme, said lid is the PP plastic member.

As the further improvement of technique scheme, said box body is the PP plastic member.

As the further improvement of technique scheme, said seal ring is a hollow silica gel circle.

The beneficial effect of the utility model is: the utility model makes seal ring install firmly through first inwall, second inwall being set and embedding seal ring wherein, is difficult for looseningly, and the upper limb of box body can accomplish in the box sealing with after seal ring is closely nested.

In addition, the utility model is provided with the buckle ear at the outer wall of box body, on lid, be provided with to break button off with the fingers and thumb, this just can through fastening break off with the fingers and thumb button and buckle ear with lid and box body be linked together, and can make lid be fastened on the top of box body, difficult leakage effectively.

The utility model has been optimized the structure of traditional milk powder box, and simple and reliable, can be widely used in sealing and preserve various milk powder.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is the assembly cutaway view that lid and the box body in the utility model is in buckling state;

Fig. 2 is the C node enlarged drawing of Fig. 1;

Fig. 3 is the blast cutaway view of the utility model.

The specific embodiment

With reference to Fig. 1～Fig. 3; A kind of milk powder box; Comprise box body 2 and with the lid 1 of box body 2 top opening pressings, it is downward first inwall 11 and second inwall 12 that the peripheral from-inner-to-outer of said lid 1 is provided with direction of extension, the slit between said first inwall 11 and second inwall 12 constitutes ring cavity 13; Be embedded with seal ring 3 in the said ring cavity 13, the upper limb of said box body 2 imbeds in the sealing circle 3.Particularly, the utility model is tetragonal box.

Further as preferred embodiment, the inside face of the outer wall of the upper limb of said box body 2 and second inwall 12 is fitted.

Further as preferred embodiment, the outer wall of said box body 2 top is provided with buckle ear 21, and the edge of said lid 1 is provided with breaking off with the fingers and thumb of buckle ear 21 fastenings and detains 14.Particularly, the length of said second inwall 12 is longer, can abut to the top of buckle ear 21, so just makes lid 1 compact more with the fastening structure of box body 2, and the claustra passage that forms simultaneously helps stopping the inside and outside mutual seepage of liquid.The said button of breaking off with the fingers and thumb 14 has 4, be distributed in respectively box body 2 around, its cooresponding buckle ear 21 also has 4.Break button 14 off with the fingers and thumb and can adopt the pivotally attached mode to connect with lid 1, or directly one-body molded, utilizing the deformability of plastics itself to make and break button off with the fingers and thumb can be that rotating shaft is freely rotated with the union end.

Further as preferred embodiment, said buckle ear 21 downward bendings, said breaking off with the fingers and thumb detained 14 and is provided with the bending end that can embed buckle ear 21 and the flange in the space between box body 2 outer walls.After said flange imbeds the space between bending end and box body 2 outer walls, no matter how external force to pull lid 1, lid 1 separation that also can not come off from the top of box body 2; Break off with the fingers and thumb after button 14 fastens with buckle ear 21, applied downward application force for lid 1, can lid 1 is drop-down, the bottom that makes the upper limb of box body 2 imbed seal ring 3.

Further as preferred embodiment, said lid 1 is the PP plastic member.
