Abstract
The utility model relates to a novel cup cover comprising an upper cover and a lower seat which is in threaded connection with the upper cover, wherein a sealing ring for matching with a water sealing neck on the inner wall of an upper edge of a bottle body is clamped on a recessed inner wall of the lower seat. The novel cup cover is characterized in that a middle ring is sheathed at the periphery of a clamping position of the lower seat and the upper cover, and the upper part of the sealing ring is clamped in a groove in the middle ring. The sealing ring is made of high-elasticity silica gel. The novel cup cover is simple in structure, durable in sealing effect, and is convenient and practical.
Description
Technical field
The utility model relates to a kind of novel bowl cover.
Background technology
Existing bowl cover commonly directly adds bowl cover on cup, bowl cover is covered on cup (as shown in Figure 1), because of bowl cover and cup with being threaded, when turning clockwise bowl cover, bowl cover can move down, and has just reached water sealing effect when the sealing ring of bowl cover inwall contacts with water shutoff neck on the cup and compresses.But the material of the sealing ring of bowl cover inwall is generally silica gel, and the back that often is squeezed is yielding, thereby causes the sealing effectiveness of bowl cover not so good, persistence is poor.
Summary of the invention
The utility model will overcome the imperfect problem of existing bowl cover sealing effectiveness, and a kind of simple in structure, novel bowl cover that sealing effectiveness is lasting is provided.
The technical solution of the utility model is:
A kind of novel bowl cover, comprise loam cake and with its by being threaded following, described following inwall that falls in engaging is useful on the sealing ring that cooperates with the water shutoff neck of the upper edge inwall of cup, it is characterized in that: described following the periphery at the position that engages with described loam cake is with a centre circle, and the top of described sealing ring is fastened in the groove of described centre circle.
Further, the material of described sealing ring is a high resiliency silica gel.
During work, bowl cover is covered on cup, the top of sealing ring is near the rim of a cup of cup, and the bottom is near the water shutoff neck of cup.Loam cake turns clockwise, move up by following of being threaded with loam cake, move certain distance on the following seat pulling sealing ring, sealing ring moves, is out of shape on beginning under centre circle and following 's the extruding, the top of sealing ring is adjacent to the water shutoff neck place of cup, again because sealing ring is bigger at the wall thickness drop at the water shutoff neck place of cup, distortion is the most serious herein, the diameter of the bottom of sealing ring at water shutoff neck place becomes big, thereby make the inner bag at water shutoff neck place of the bottom of sealing ring and cup closely cooperate, reach the effect of sealing water shutoff.When being rotated counterclockwise loam cake, centre circle moves down certain distance, and sealing ring recovers reset condition under self elastic force, and the diameter of sealing ring at water shutoff neck place becomes original less size again, and can take out cup this moment with bowl cover.
According to technique scheme, produced product, by practical application, the instructions for use when having satisfied product design preferably.
Advantage of the present utility model: simple in structure, sealing effectiveness is lasting, and is convenient and practical.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
With reference to Fig. 1-Fig. 4, a kind of novel bowl cover described in the utility model, comprise loam cake 1 and with its by being threaded following 3, described following 3 inwall engaging that falls in is useful on the sealing ring 2 that cooperates with the water shutoff neck 6 of the upper edge inwall of cup 5, described following 3 periphery at the position that engages with described loam cake 1 is with a centre circle 4, and the top of described sealing ring 2 is fastened in the groove of described centre circle 4.
The material of described sealing ring 2 is a high resiliency silica gel.
During work, bowl cover is covered on cup 5, the top of sealing ring 2 is near the rim of a cup of cup 5, and the bottom is near the water shutoff neck 6 of cup 5.Loam cake 1 turns clockwise, move up by following 3 of being threaded with loam cake 1, move certain distance on the following seat 3 pulling sealing rings 2, sealing ring 2 moves, is out of shape on beginning under centre circle 4 and following 's 3 the extruding, the top of sealing ring 2 is adjacent to water shutoff neck 6 places of cup 5, again because sealing ring 2 is bigger at the wall thickness drop at water shutoff neck 6 places of cup 5, distortion is the most serious herein, the diameter of the bottom of sealing ring 2 at water shutoff neck 6 places becomes big, thereby make the inner bag at water shutoff neck 6 places of the bottom of sealing ring 2 and cup 5 closely cooperate, reach the effect of sealing water shutoff.When being rotated counterclockwise loam cake 1, centre circle 4 moves down certain distance, and sealing ring 2 recovers reset condition under self elastic force, and the diameter of sealing ring 2 at water shutoff neck 6 places becomes original less size again, and can take out bowl cover cup 5 this moment.
The described content of this specification embodiment only is enumerating the way of realization of utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
Claims (2)
1. novel bowl cover, comprise loam cake and with its by being threaded following, described following inwall that falls in engaging is useful on the sealing ring that cooperates with the water shutoff neck of the upper edge inwall of bottle, it is characterized in that: described following the periphery at the position that engages with described loam cake is with a centre circle, and the top of described sealing ring is fastened in the groove of described centre circle.
2. a kind of novel bowl cover according to claim 1 is characterized in that: the material of described sealing ring is a high resiliency silica gel.
