Abstract
The utility model discloses a water filling opening of a flexible water container. The water filling opening comprises an opening portion and a cover body. The cover body comprises a cylindrical stopper and a cover portion, one end of the stopper is connected with the cover portion, the stopper is provided with threads, when the water filling opening is closed, the stopper is in a pipe-shaped part of the opening portion. A water sealing ring is arranged at one end, close to the cover portion, of the stopper, and the diameter of the water sealing ring is larger than the inner diameter of the part inside the pipe-shaped part of the opening portion. A twisting structure is arranged on the cover portion. A person can conveniently place the stopper in the pipe-shaped portion of the opening portion by just rotating the cover body. The water filling opening has the advantages of being simple in structure and convenient to operate and ensuring that the flexible water container is high in sealing strength, further has the advantages of being small in size, and can be placed on the lateral side of the container, and therefore the using effect of flexible water containers like water pillows and water cushions is improved. The water sealing ring can prevent water from leaking through the threads, and improves sealing effect of the water filling opening. The cover body can be conveniently rotated through the twisting structure to ensure that the water filling opening can be more conveniently opened or closed.
Description
Technical field
The utility model relates to the flexible containers filled with water such as a kind of water pillow, water cushion, water bed, warmer treasured, is more specifically the filling opening of flexible container filled with water, belongs to the articles for daily use technical field.
Background technology
At present, the daily necessities of the water-fillings such as water pillow, water cushion, water bed, warmer treasured progressively enters people's life, and it is especially fiery to sell on the net.For convenience of transportation and the storage of these water-filling daily necessitiess, often by user's water-filling voluntarily, these water pillows, water cushion, water bed, warmer treasured etc. generally have filling opening for this reason.
The filling opening of the flexible containers filled with water such as existing water pillow, water cushion, water bed, warmer treasured comprises oral area and the lid of tubulose, and the kind of its lid is a lot, is summed up and is broadly divided into inner plug body and outsourcing lid.
The inner plug body is generally circular cylindrical shape, the tubular inner wall interference fit of inner plug body and oral area by circular cylindrical shape, flexible container filled with water is sealed, this filling opening has advantages of that volume is little, but it easily makes the inner plug body break away from when container is squeezed, simultaneously, when the inner plug body was packed the tubulose of oral area into,, there was operational inconvenience in the larger power of needs.The outsourcing lid is the cap shape, it is inboard and outer tubular wall interference fit by the lid of cap shape, flexible container filled with water is sealed, and for strengthening this filling opening sealing intensity, generally clad is external outside arranges one again and strengthens cover, although this filling opening has sealing intensity preferably, but its complex structure, volume ratio is larger simultaneously, generally can only be arranged on front or the reverse side of container, be difficult to be arranged on the side of container, affected the flexible container filled with water results of use such as water pillow, water cushion.
The utility model content
For above-mentioned situation, the problem that the utility model quasi-solution is determined is to provide a kind of filling opening of simple in structure, sealing intensity is high, easy to operate, volume is little flexible container filled with water.It can be arranged on filling opening on the side of container, has improved the flexible container filled with water results of use such as water pillow, water cushion.
For reaching above-mentioned purpose, the utility model has adopted following technical scheme: a kind of filling opening of flexible container filled with water, it comprises oral area and lid, the main body of described oral area is tubulose and the bottom of oral area is base, described lid comprises stopper and the cap of circular cylindrical shape, and an end of described stopper is connected with cap, and described stopper is provided with screw thread, during described filling opening sealing, described stopper is in the tubular portion of oral area.
Described stopper has the water shutoff circle near an end of cap, and the diameter of described water shutoff circle is greater than the internal diameter at the oral area tubular portion.
Described cap is provided with and turns structure, and the described structure that turns can be arranged on the screwdriver notch on cap, and described screwdriver notch is in a relative side of stopper; The described structure that turns also can be arranged on the block of cap side; Describedly turn the axial dentation that structure can also be arranged on the cap periphery.
Adopt such scheme, the filling opening of flexible container filled with water of the present utility model, because the stopper of lid is provided with screw thread, because screw thread has directional tagging, therefore as long as rotating cover just can conveniently be placed in stopper in the tubulose of oral area.Have advantages of simple in structurely, easy to operate, make simultaneously the sealing intensity of flexible container filled with water high, also can have the characteristics that the filling opening volume is little, filling opening can be arranged on the side of container, improved the flexible container filled with water results of use such as water pillow, water cushion.
Stopper has the water shutoff circle near an end of cap, and the diameter of water shutoff circle is greater than the internal diameter at the oral area tubular portion.Can prevent that like this sealing passes through the screw thread seepage, increase the sealing effectiveness of filling opening.
Cap is provided with and turns structure, can facilitate rotating cover, makes the opening and closing operation of filling opening more convenient.
