The specific embodiment
Below in conjunction with Figure of description and embodiment, content of the present invention is elaborated:
The embodiment schematic diagram of a kind of lid with small container provided by the invention as shown in Figure 1 to Figure 7 shows the.
It comprises bottle cap 1, and described bottle cap 1 is upper and lower penetrating annular arrangement, is provided with negative thread 2 on the internal face of annular arrangement, and described negative thread 2 matches with the outside thread of body, the utility model bottle cap 1 can be covered tightly or seal the opening part covering tightly at body.It is characterized in that: it also comprises small container 3, be located at, on small container 3, small container 3 played to top cover 4 and the push rod 7 of airtight effect, described small container 3 is the uncovered hollow cavity in upper end, the outside wall surface of small container 3 is provided with the connection side that is connected with the upper end of the annular arrangement of bottle cap 1 along 5, and connection side along under small container 3 outer side surface and be provided with between the ring-shaped inner wall face of negative thread 2 and be provided with gap, this gap can hold the opening part wall thickness of the body matching with it, the bottom of described small container 3 is provided with easy opening 6, between described easy opening 6 and top cover 4, be provided with push rod 7.By pressing top cover 4, make the downward pushing tow of push rod 7 open easy opening 6, the dry that makes to be contained in small container 3 falls into the liquid being contained in bottle.
The lower edge of described top cover 4 and small container 3 are set to seal tight fit connection between uncovered upper edge, described top cover 4 comprises with the small container friction tight base portion 4-1 of the 3 uncovered sealing in upper end and is located at the thrust cap 4-2 on base portion 4-1, described thrust cap 4-2 is arch, the middle part of thrust cap 4-2 medial surface is provided with spacing flange collar 4-3, the higher stroke of height that arch thrust cap 4-2 arches upward is larger, commute opening 6 applied pressures are also larger, more being easy to easy opening 6 opens, and the mouth that easily opening 6 is opened is just larger, the dry of being convenient in small container 3 falls into bottle, and spacing flange collar 4-3 makes when top cover 4 and small container 3 are closely connected, spacing flange collar 4-3 is limited to the top of push rod 7 in spacing flange collar 4-3, prevent when pressing thrust cap 4-2, the top positioning of push rod 6, and be difficult to realize the thrusting action of 7 pairs of small containers of push rod, the 3 easy openings 6 in bottom, the outer wall of the junction of described base portion 4-1 and thrust cap 4-2 has been provided with the button collar 4-4 of position-limiting action, button collar 4-4 had both guaranteed that top cover 4 can be fixed on small container 3, also played the effect of sealing simultaneously, the periphery wall of the base portion 4-1 of the below of described button collar 4-4 is provided with several seal convexity circle 4-5 sealing, seal convexity circle 4-5 can cover tightly on small container 3 top cover 4 closely, has played sealing function, and the number of seal convexity circle 4-5 can be three or four, described top cover 4 is made by the flexible material that can press, and is convenient to press.
The top of described small container 3 is cylindrical and is positioned at bottle cap 2, the sealing cover body 8 with easy opening 6 that its lower end is back taper; The upper opening of the columniform inner peripheral wall on described small container 3 tops is bigger, is more easy to top cover and small container to cover tightly; The setting of the sealing cover body 8 of described back taper, makes the dry in small container 3 more easily along the wall tilting, concentrate and fall into bottle; The columniform upper end on described small container 3 tops is provided with the button draw-in groove 9 matching with the button collar 4-4 of top cover 4, while pressing top cover 4, button collar 4-4 is stuck on button draw-in groove 9, and top cover 4 can be fixed on small container 3, prevents that top cover 4 from falling in small container 3 after pressing simultaneously.
One side of described back taper sealing cover body 8 bottoms is provided with openable easy opening 6, the gradient on the inclined-plane of described easy opening 6 is less than the gradient of tapered slope, the material of being convenient to like this in small container 3 falls into bottle, and discharging is convenient, and described easy opening 6 is partial to a side of small container 3 line of centerss.
Described push rod 7 is positioned at bias on the line of centers of small container 3 and is fixedly arranged on easy opening 6, and push rod 7 is positioned at the centre of sealing cover body 8, and the other end of push rod 7 is positioned at spacing flange collar 4-3.Push rod 7 bias are located on easy opening 6, and are positioned at the centre of sealing cover body 8 simultaneously, and stress point can be concentrated on the eccentric position of easy opening 6, and stressed can not scattering and stress point maximum, is easy to opening of easy opening 6 more.
Be made as being connected between described easy opening 6 and sealing cover body 8 and incompletely easily disconnect, described incomplete easily disconnecting comprises the connecting bridge 11 that is easy to the connecting bridge 10 disconnecting and is not easy to disconnect, the described connecting bridge 10 that disconnects of being easy to is less than the clamping ring of the thickness of sealing cover body 8 for thickness, be easy to connecting bridge 10 thinner thicknesses that disconnect, being convenient to user opens, but guaranteed the leak tightness with sealing cover body 8 simultaneously, the described connecting bridge 11 that is not easy to disconnect is positioned at the highest point that easy opening 6 is connected with sealing cover body 8 and is only set to a bit of, the wall thickness of the described connecting bridge 11 that is not easy to disconnection is identical with the wall thickness of sealing cover body 8, while preventing from pressing thrust cap 4-2, whole easy opening 6 is fallen in bottle.
The present invention also comprises the protruding peak 12 that can prevent that thrust cap 4-2 from surprisingly being pushed in storage, transportation and sales process, described protruding peak 12 is arranged at the edge, upper end of the annular arrangement of bottle cap 1, described protruding peak 12 is circular ring type waveform, and the height at protruding peak 12 is higher than the height of the top cover 4 after closely cooperating with small container 3.Described protruding peak 12 is symmetrical, and 2-4 is individual for better, and 12 pairs, protruding peak thrust cap 4-2 has played protective effect.
Described top cover 4 and small container 3 are for vacuumizing rear tank or filling vacuum sealed package.Adopt lid of the present invention, can realize the dry in the liquid beverages such as beverage and solvent (being generally pure water) are separated to packing separately, in the situation that without adding the harmful additives such as antioxidant or anti fouling composition, can extend the shelf-life of the dry in small container 3, thereby greatly extended the sale shelf-life of liquid beverage, greatly lower short the caused a large amount of wastes of shelf-life because of beverage, reduced environmental pollution, lowered the cost of goods sold of enterprise.
