Abstract
The utility model discloses a tea leaf tin with vent holes. The tea leaf tin comprises a cylindrical tin body and a tin cover which is arranged on the outside of a port of the tin body in a sleeved mode. The tin body and the tin cover are located in the same axis, the vent holes are formed both in the lateral wall at the edge of the tin cover and the lateral wall of the port of the tin body, and when the tin cover rotates around the axis, the vent holes in the tin cover and the vent holes in the tin body can be sealed in a staggered mode. Compared with the prior art, the tea leaf tin is saving in labor during covering and good in sealing effect; has the advantages of being simple in structure, low in cost, and durable.
Description
Technical field
The utility model relates to tea can, relates in particular to a kind of tea can that seals and open of being convenient to air extractor vent.
Background technology
Tea can is the container commonly used of storage tealeaves, and people have opened seal-packed tealeaves to some and have been placed in tea can, takes into account fragmentary edible and sealing.Existing simple and easy tea can has a can body and is enclosed within the outer cover of can body port, the size shape of the outer wall of can body port and cover inwall matches, when cover is buckled in the can body port, rely on both contact axial planes to seal, the defect of this tea can is: when cover contact tank body port also continues downwards on time, gas in the tank chamber can't escape, gradually reduced, then produce power upwards, stop cover further to move down, thereby cause, cover painstakingly, cover is difficult to put in place, sealing surface reduces, and sealing effectiveness weakens.
The utility model content
The utility model is the problems referred to above that will solve prior art, proposes a kind of band air extractor vent, can get rid of pressurized air, covers the tea can of rear good seal.
For solving the problems of the technologies described above, the technical scheme that the utility model proposes is a kind of tea can with air extractor vent of design, comprise columniform tank body and the cover that is enclosed within the tank body port outside, tank body and cover are in same axis, on the sidewall at cover edge and on the sidewall of tank body port, all be provided with air extractor vent, the air extractor vent when cover rotates around described axis on cover and tank body can misplace airtight.
Above-mentioned air extractor vent can be the ventilation elongated slot, and the major axis of ventilation elongated slot is parallel with described axis.
Above-mentioned air extractor vent also can be the ventilation elongated slot, and major axis and the described axis of ventilation elongated slot form angle, and the ventilation elongated slot on cover intersects mutually with the ventilation elongated slot on tank body.
Above-mentioned air extractor vent can also comprise the ventilation circular hole of a plurality of equal diameters, and the ventilation circular hole is equally spaced along described axis direction, and the spacing of adjacent ventilation circular hole is less than the diameter of ventilation circular hole.
Compared with prior art, the utility model covers laborsaving, good sealing effect; Have simultaneously simple in structure, with low cost, long-lived advantage.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in detail, wherein:
Fig. 1 is the cutaway view of the first embodiment;
Fig. 2 is the right elevation of Fig. 1;
Fig. 3 is the cutaway view of the second embodiment;
Fig. 4 is the decomposing schematic representation of the second embodiment tank body and cover;
Fig. 5 is the cutaway view of the 3rd embodiment;
Fig. 6 is the right elevation of Fig. 5.
The specific embodiment
The utility model discloses a kind of tea can with air extractor vent, the cover 2 that it comprises columniform tank body 1 and is enclosed within the tank body port outside, tank body and cover are in same axis, on the sidewall at cover edge and on the sidewall of tank body port, all be provided with air extractor vent, the air extractor vent when cover rotates around described axis on cover and tank body can misplace airtight.
During use, first cover 2 upper vent holes are aimed to the lower cover of lid with the air extractor vent on tank body 1, air in tank is discharged by air extractor vent, and cover can steadily cover down, after cover covers down fully, rotates cover, make the air extractor vent dislocation on cover and tank body, tea can is inside and outside isolated, and in tank, tealeaves is sealed.When need are opened cover, as directly cover upwards pulled out, in tank, produce negative pressure, cover can't be extracted; Cover need be rotated, cover is communicated with the air extractor vent on tank body, then cover is upwards pulled out, the tank outer air can be supplemented and be flowed in tank, and cover can be opened.
It may be noted that and need to closely cooperate between tank body port and cover, can reach good sealing effectiveness.Tank body and cover and material can be plastics or metal.
In the first embodiment shown in Fig. 1, air extractor vent is ventilation elongated slot 3, and the major axis of ventilation elongated slot is parallel with described axis.Shown in Fig. 2 is the right elevation of tea can in Fig. 1.
In the first embodiment, while covering cover, the ventilation elongated slot on cover and tank body to be aimed at, because ventilation elongated slot in this example is less at the area of conter of vertical, aim at two ventilation elongated slots and relatively take great energy.So in a second embodiment the shape of ventilation elongated slot is improved.
Referring to the second embodiment shown in Fig. 3, air extractor vent is ventilation elongated slot 3, and major axis a and the described axis b of ventilation elongated slot form angle, and the ventilation elongated slot on cover intersects mutually with the ventilation elongated slot on tank body.In this example, ventilation elongated slot 3 is larger at the area of conter of vertical, and the ventilation elongated slot on cover and the ventilation elongated slot on tank body are without too accurate to obtaining.In the tank body shown in Fig. 4 and cover decomposing schematic representation, cover to anticlockwise an angle.To cover cover, narrate its principle of work as example: downwards when cover covers, initial stages two, the ventilation elongated slot did not communicate, and in tank, air is compressed, but this moment, the air compressing amount was little, cover can continue to move down, after continuing to move down, two ventilation elongated slots communicate, and the tank compressed air is discharged, cover can cover bottom smoothly, then rotate cover, two ventilation elongated slot sealings, tea can is sealed.
In the first and second embodiment, the area of ventilation elongated slot is larger, can reduce the mechanical strength of cover, so, in the 3rd embodiment, air extractor vent is divided into to the ventilation circular hole 4 of a plurality of equal diameters, as shown in Figure 5, because ventilation circular hole area is less, the mechanical strength of cover is improved.From the right elevation shown in Fig. 6, finding out, the ventilation circular hole is equally spaced along described axis direction, and the spacing L of adjacent ventilation circular hole is less than the diameter R of ventilation circular hole.When cover moves down, must have the ventilation circular hole to ventilate like this, this routine sealing principle is identical with the first embodiment, does not repeat them here.The spacing L of adjacent ventilation circular hole be as long as, less than the diameter R of ventilation circular hole, can guarantee when cover moves down to have the ventilation circular hole to ventilate, so to spacing L less than the concrete numerical value of diameter R without restriction.
Above embodiment is only casehistory, non-providing constraints.Anyly do not break away from spirit of the present invention and category, and, to its equivalent modifications of carrying out or change, all should be contained among the application's claim scope.
