Description

Drinking cup without plastic plug

Technical Field

The utility model relates to a drinking cup especially relates to a no plastic plug drinking cup.

Background

Present drinking cup generally includes cup, plastics stopper and bowl cover, and plastics stopper lid closes (stopper is tight or is screwed) at the rim of a cup inboard of cup, and the bowl cover generally is the spiral bowl cover, and the spiral bowl cover closes the rim of a cup outside at the cup with spiral mode lid, and the spiral bowl cover generally can't play sealed effect, and what mainly play sealed effect is the plastics stopper, and in order to pour the water convenience, generally still should set up the apopore and set up the ooff valve on the plastics stopper. Therefore, the plastic plug is complex in structure, and particularly, the switch valve for water outlet can not be cleaned almost, so that bacteria breeding is easy to cause, the plastic plug is not easy to clean, and the plastic plug is not healthy and environment-friendly enough.

In order to solve the aforesaid and be difficult to wash and lead to bacterial growing, the problem of healthy environmental protection inadequately, cup mouth department through at the cup sets up the silica gel ring and connects with the mode that cup joints, silica gel belongs to environmental protection material and has better deformability, screw at cup mouth department back when the spiral bowl cover, the top medial surface of spiral bowl cover compresses tightly on the silica gel ring, the top medial surface of spiral bowl cover constitutes the seal structure of cup mouth with the silica gel ring, the effect is equivalent to rubber seal, sealed effect is far better than the plastic plug far away, and the silica gel ring can be pulled down at any time and wash, need not to set up the apopore and set up the ooff valve like the plastic plug, moreover, the steam generator is simple in structure, easy.

However, the existing silica gel ring is too easy to separate from the cup mouth, is difficult to perform the shaping and sealing functions, is easy to leak water, and has poor sealing effect.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a no plastic stopper drinking cup, this kind of no plastic stopper drinking cup simple structure, sealed effect is better. The technical scheme is as follows:

the utility model provides a no plastic plug drinking cup, includes cup, spiral bowl cover and silica gel ring, and the upper end of cup is equipped with the rim of a cup, and the lateral wall of rim of a cup is equipped with the external screw thread, and the inside wall of spiral bowl cover is equipped with the internal thread, and the spiral bowl cover screws on the lateral wall of rim of a cup through internal thread, external screw thread, and the silica gel ring cup joints the rim of a cup department at the cup, and the spiral bowl cover screws behind rim of a cup department, and the top medial surface of spiral bowl cover compresses tightly on: the silica gel ring comprises an outer ring and an inner ring, the inner ring is connected to the top of the outer ring, and an annular clamping groove is formed between the inner ring and the outer ring; the outer side wall of the cup opening is provided with an outer clamping ring protruding outwards and an outer clamping ring groove recessed inwards, and the outer clamping ring groove is positioned below the outer clamping ring; the inner wall of the outer ring is provided with an inner clamping ring groove which is concave outwards and an inner clamping ring which is convex inwards, and the inner clamping ring is positioned below the inner clamping ring groove; the silica gel ring is sleeved on the cup mouth through the annular clamping groove, the outer clamping ring is positioned in the inner clamping annular groove, and the inner clamping ring is positioned in the outer clamping annular groove.

The spiral cup cover is generally made of polypropylene (PP) meeting food hygiene standards and can also be made of stainless steel, and the spiral cup cover can be directly used as a cup for drinking water.

Compared with the prior art, the utility model, have following advantage:

the utility model discloses a no plastic plug drinking cup, through setting the silica gel ring to outer loop and inner ring, ring groove between outer loop and the inner ring, at first ensure the silica gel ring can install in cup opening department with the mode that directly cup joints, it is further, set up interior joint annular groove between outer loop and the cup opening outer wall, interior joint ring, outer joint annular groove is in order to constitute scarf joint structure between the two, make the silica gel ring cup joint more firmly and compact behind the cup opening, no specific direction exogenic action is difficult for breaking away from, sealed effect is better.
