Detailed description of the invention
In order to make the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with embodiment and accompanying drawing, the present invention is described in more detail.
Embodiment 1:
With reference to shown in Fig. 1-6, lid of the present invention, the enclosing cover 1 comprising inner cap 2 and be rotationally connected with inner cap 2.Inner cap 2 is provided with through opening, and enclosing cover 1 comprises the roof 101 for closing openings, and the medial surface of roof 101 is provided with cyclic lug 105, and when enclosing cover 1 is covered on inner cap 2, cyclic lug 105 forms interference fit with the inwall of inner cap 2.During use, inner cap 2 is installed on container, specifically can adopt and be threaded or the mode such as interference fit, afterwards, enclosing cover 1 is made to be covered in the opening of inner cap 2 by rotating enclosing cover 1, now, enclosing cover 1 forms interference fit by cyclic lug 105 and inner cap 2, thus ensures the sealing property between enclosing cover 1 and inner cap 2.
As shown in FIG., enclosing cover 1 also comprises the sidewall 102 connected with roof 101, and sidewall 102 is positioned at the outside of cyclic lug 105, the lateral surface of inner cap 2 offers annular breach 201, when enclosing cover 1 is covered on inner cap 2, sidewall 102 is coated on annular breach 201 at least partly.Like this, when enclosing cover 1 covers, the sidewall 102 of enclosing cover 1 is on same periphery with the sidewall 102 of inner cap 2.
In the present invention, further, enclosing cover 1 is closed by clamping and inner cap 2, like this, easy to use.As preferably, sidewall 102 is provided with the radial protrusion 103 pulling to open enclosing cover 1 for staff.During use, application force can be applied by pulling this radial protrusion 103 pairs of enclosing covers 1, thus make it open relative to inner cap 2.
For preventing enclosing cover 1 from arbitrarily being opened, lid of the present invention also comprises hand sheet 6, sidewall 102 is provided with the banking stop 104 extended radially outwardly along enclosing cover 1, and hand sheet 6 is connected with inner cap 2 and spacing by banking stop 104.This banking stop 104 opponent sheet 6 produces and stops, namely hand sheet 6 part is positioned on banking stop 104, and it has two legs, and these two legs are passed by the both sides of banking stop 104 and are connected with inner cap 2 respectively.Only when this hand sheet 6 being torn, can enough open enclosing cover 1.This structure can also adopt other replacement scheme, limits, prevent from arbitrarily being opened as long as enclosing cover 1 and inner cap 2 can be produced position in the early stage.
Enclosing cover 1 and being rotationally connected of inner cap 2 can adopt the mode of bearing pin to realize, and in the present invention, are connected between enclosing cover 1 with inner cap 2 by connecting strap 5, connecting strap 5 are formed with the folding line rotated relative to inner cap 2 for enclosing cover 1.When opening or closing enclosing cover 1, enclosing cover 1 all rotates around this folding line.This mode, forms butterfly hinge by forming connecting strap 5 creasy, is convenient to enclosing cover 1 and produces elasticity relative to inner cap 2 and stir, easy to use.
In the present invention, enclosing cover 1, inner cap 2 and connecting strap 5 are structure as a whole, this mode, are convenient to processing.
Preferably, lid of the present invention also comprises spoon 4, and spoon 4 is connected with the inwall of inner cap 2, and can be torn by inner cap 2 under external force.That is, spoon 4 and inner cap 2 only part contact, when user exerts oneself a little, can take off spoon 4 from inner cap 2.
As preferably, the medial surface of roof 101 is provided with two relative snap-latch pieces 3, and snap-latch piece 3 is respectively arranged with relative spacing preiection, and spoon 4 can snap between two snap-latch pieces 3.Like this, after spoon 4 takes off, can be positioned between snap-latch piece 3, and be undertaken spacing by spacing preiection, avoid it to drop out.
In the present invention, spoon 4 has handle portion 401 and spoon portion 402, and handle portion 401 is provided with through hole 403 near the one end in spoonful portion 402, and spoon portion 402 is by the arc extremely reduced gradually away from handle portion 401 one end height dimension near handle portion 401 one end.This mode, the position connected with spoon portion 402 in handle portion 401 arranges through hole 403, in use, when especially containing milk powder, milk powder can be avoided to be adhered on spoon.In addition, spoon portion 402 is set to arc, and its end (one end away from handle portion) is more shallow, like this, is convenient to, and is easy to use.
Lid can be chosen as metal, plastics or other conventional materials, and the lid material of the present embodiment 1 is PP resin.
