Description

A kind of cup for preventing that packing ring from coming off

Technical field

The utility model is related to a kind of cup, the cup lid for more particularly to preventing packing ring from coming off.

Background technology

It is well known that general cup includes cup, cup lid, cup lid has threaded side wall and bottom surface, at ring cowling inwall bottom Face, which is additionally provided with a circle caulking groove, caulking groove, can all be provided with a packing ring, and the effect of packing ring is leaked when being and preventing cup from standing upside down or tilting Water, the packing ring is typically all food grade silicone packing ring, and running into hot water has larger extensibility.The packing ring typically start it is fixed compared with It is good, but use time is long, especially repeatedly contains after hot water, easily upholds and is come off from embedding groove because of heat.Put into manually again Go, it may appear that inlay situation incessantly, cause leak, many worries are added to user.

Utility model content

The utility model is based on above-mentioned defect of the prior art, and asking for cup lid can be departed from by solving packing ring when cup is opened Topic.

The utility model purpose is, can prevent cup lid and cup because it is poorly sealed and caused by leak or be not incubated existing As meeting consumer demand.

In order to realize the purpose of this utility model, the utility model is adopted the following technical scheme that：

A kind of cup for preventing that packing ring from coming off, including cup, cup lid, wherein cup lid include lid, packing ring, the interior bottom of lid Wall has the annular caulking groove of mounting gasket, and it is convex provided with what is be adapted with the pothole of caulking groove inwall that caulking groove inwall is additionally provided with pothole, packing ring Rise, the pothole reinforces the concaveconvex structure of lid and packing ring with both raised formation.

Described concaveconvex structure is located at the packing ring, the bottom wall of the caulking groove or side wall, and quantity is 4-6.

The pothole is cylindric hole, and the projection is spherical, and the diameter of the pothole is less than the raised diameter 1mm-2mm；Or, the pothole is cube shape hole, the raised trapezoidal shape small for outer imperial palace, the length and width size of the pothole Less than the length and width size 1mm-2mm of the raised outer end.

The packing ring selects silica gel material, and the lid selects plastics or metal material.

By using above-mentioned technical scheme, the utility model is by improving the cup lid for preventing that packing ring from coming off, in original cup On the basis of lid, increase concaveconvex structure between lid and packing ring, improve the fastness that packing ring is combined with lid, improve cup and use Reliability.

Brief description of the drawings

The utility model is described in detail with preferred forms below in conjunction with the accompanying drawings.

Fig. 1 is the front schematic view of packing ring；

Fig. 2 is the side schematic view of packing ring；

Fig. 3 is the schematic bottom view of lid；

Fig. 4 is the installation diagram of water channel and purifier；

Fig. 5 is concaveconvex structure diagrammatic cross-section in most preferred embodiment.

Part in figure representated by label is:1. packing ring, 2. is raised, 3. lids, 4. caulking grooves, 5. potholes.

Embodiment

Referring to the drawings, prevent that the technical scheme for the cup most preferred embodiment that packing ring comes off from being retouched in detail to the utility model State.

It is the packing ring 1 described in presently preferred embodiment referring to Fig. 1, Fig. 2, it is silica gel material, in the border pair of packing ring 1 Title is dispersed with six.

It is the lid 3 described in presently preferred embodiment referring to Fig. 3, Fig. 4, it is hard plastic or metal material, in lid The inner bottom surface of body 3 is provided with caulking groove 4, and the effect of caulking groove 4 is that, in order to place packing ring 1, in general, the diameter of packing ring 1 is slightly larger than caulking groove 4 Diameter, the formation of packing ring 1 and caulking groove 4 is interference fitted, it is to avoid packing ring 1 comes off.It is additionally provided with the border of caulking groove 4 and raised 2 Put what size shape was adapted.

Referring to Fig. 5, after lid 3 is assembled with packing ring 2, projection 2 constitutes convex-concave structure, and presently preferred embodiment with pothole 5 In, pothole 5 is cylindric hole, projection 2 to be spherical, and pothole 5 diameter be less than described raised 2 diameter 1mm-2mm, work as dress Ball bumps 2, are respectively pressed into corresponding interior pothole 5 by timing with external force.If in cup in use, putting into hot water, The heat of ball bumps 2 expands, and extrudes pothole 5, because the material of pothole 5 is generally rigid plastics or aluminium alloy, its coefficient of expansion is less than The ball bumps 2 of silica gel material, can make ball bumps 2 increasingly tighter, inlay more firmly, heat is more difficult to come off.

The utility model is simple in construction, easily realizes, user is easily operated in use, can effectively prevent packing ring Come off the leak gas leak phenomenon caused, reduces using worried, is extensively welcome by user.

Certainly, the utility model is not limited to the example above, and the product applied includes but cup of not restricting water supply, not limited capacity amount, It will be apparent to those skilled in the art that technical scheme, do not departing from spirit or scope situation of the present utility model Under, such as, by the circular hole side of being changed to hole etc., this modifications and changes done to the utility model in the utility model claim and In the range of its equivalent substitution, the utility model covers such modifications and changes.
