Description

Anti-toppling cup sleeve

Technical Field

The invention relates to the technical field of daily necessities, in particular to an anti-toppling cup sleeve.

Background

The cup sleeve is used as an auxiliary accessory of the cup and is usually sleeved on the outer ring of the cup to play a role in heat insulation and skid resistance, when the cup is placed on a desktop, the cup often topples over instantly due to careless mistaken collision to enable liquid of the cup to flow out, and when the cup is placed on the desktop in a bumpy environment (such as a table top in a train or a caravan), the cup also topples over due to bumping. Particularly, the glass can not only overturn the liquid in the glass body after being poured, but also easily fall to the ground to cause breakage.

At present, some cup sleeves with suckers at the bottoms are also arranged on the market, and although the cup sleeves can play a role in fixing a cup, the cup sleeves are extremely inconvenient to take and labor-consuming because the suction force of the suckers exists all the time, and the cup body liquid is easy to splash and spill out in the moment of canceling fixation.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides the anti-toppling cup sleeve which is simple in structure and convenient to use, can prevent the cup from being toppled over easily while playing a role of heat insulation and skid prevention, and can conveniently make the negative pressure in the fixed sucker disappear and the cup can be taken easily.

The technical scheme adopted by the invention for solving the technical problems is as follows: an anti-toppling cup sleeve is in a cylindrical shape with an upper opening, the cup sleeve is made of flexible materials, a sucker is arranged below the cup sleeve and provided with a through hole communicated with the inside of the cup sleeve, a groove surrounding the inner surface for a circle is arranged on the inner surface of the middle upper part of the cup sleeve, the inner surface above the groove is a first contact surface, the inner surface below the groove is a second contact surface, an air guide part communicated with the groove and the through hole is arranged on the second contact surface, when a container is inserted on the cup sleeve, the first contact surface is tightly attached to the outer wall of the container in interference fit, at the moment, negative pressure is formed inside the sucker after air is exhausted, the first contact surface can be deformed by pressing the groove, and therefore external air enters from a gap between the first contact surface and the container, and enters the sucker through the air guide part and the through hole.

In the above technical solution, preferably, the air guide member is one or more vent grooves disposed on the second contact surface, and the vent grooves communicate the groove and the through hole. The air guide part with the structure has simple structure and good use effect.

In the above technical solution, as another preferable solution, the second contact surface is provided with concave grains, and the concave grains are communicated to form the air guide member. The concave grains are distributed on the second contact surface, the structure of the air guide part is simple to process, the effect is good, and the shape of the surface grains is more distinctive.

In the above technical scheme, preferably, the middle upper portion in the groove is provided with a plurality of vertical ribs, and the vertical ribs do not protrude from the first contact surface in a normal state. Set up like this, can make under container and the first contact surface in close contact with's state, through pressing from the glass holder outside during the recess, because the existence and the restriction of vertical protruding muscle play a supporting role, utilize lever principle can make and produce great space more easily between container and the first contact surface, be convenient for outside air gets into to the sucking disc in.

In the above technical solution, preferably, the vertical surface and the bottom surface of the vertical rib form an included angle or an arc angle. The arrangement is that when the groove is pressed, the upper half area of the first contact surface can be inclined outwards through the lever principle, and external air can enter conveniently.

In the above technical solution, preferably, the vent grooves are arranged in a straight line, and include a first section on the second contact surface and a second section on the bottom surface of the cup holder. Due to the arrangement, the length of the vent groove can be shortest, and the fastest time for external air to enter the sucker through the vent groove is achieved while the strength of the overall structure of the cup sleeve is guaranteed.

In the above technical solution, preferably, the number of the vent grooves is 8, and the vent grooves are annularly and uniformly distributed on the second contact surface of the cup sleeve.

In the above technical solution, preferably, the surface roughness of the outer surface of the sleeve is 3.2 μm or more. Thus, a good anti-skid effect is achieved.

In the above aspect, the surface roughness of the first contact surface of the sleeve is preferably 2 μm or less. The cup sleeve with the container can be more tightly contacted with the first contact surface without air leakage, the cup sleeve with the container can be firmly fixed by the sucker, and the cup sleeve can be more easily taken down from the container.

In the above technical scheme, preferably, the cup sleeve is made of one of rubber, silica gel and plastic.

The invention has the beneficial effects that: simple structure, convenient to use plays thermal-insulated skid-proof while, can make the cup be difficult for being pushed down, can make the negative pressure in the sucking disc after fixing disappear very conveniently moreover through the setting of air guide part and annular recess, can easily take.
