Patent Application
20170073127
1. Field of Invention
The present invention relates to a bottle for containing liquid and, more particularly, to a nozzle for a bottle.
2. Related Prior Art
A cap is often used to close a bottle that contains liquid such as body wash, shampoo, detergent, lotion, and perfume. Thus, the liquid will not be leaked from the bottle. The liquid can be poured from the bottle after the cap is removed from the bottle. However, an excessive amount of the liquid might easily be poured from the bottle, and this is a waste.
A nozzle can be used to control the amount of the liquid dispensed from the nozzle. The nozzle is pressed to dispense the liquid from the bottle. The deeper the nozzle is pressed, the larger the amount of the liquid is dispensed.

The color of the ring 20 is dull, and it is difficult to clean the ring 20. Hence, the sheath 60 is provided around the ring 20. However, it is difficult to adhere the sheath 60 to the ring 20. Moreover, the sheath 60 includes a sharp lower edge that would cut a user.
The present invention is therefore intended to obviate or at least alleviate the problems encountered in prior art.
It is the primary objective of the present invention to provide a bottle with a safe nozzle.
To achieve the foregoing objective, the nozzle includes a ring, a tube, a piston and a sheath. The ring includes an upper portion and a lower portion. The tube extends in the ring. The piston is connected to the tube and partially located out of the ring. The sheath is made of metal and includes a first annular flange at an end and a second annular flange at another end. The sheath is arranged around the ring. The first annular flange is placed against the upper portion of the ring and the second annular flange is placed against lower portion of the ring when sheath is provided around the ring. Thus, the sheath is kept on the ring without the use of any adhesive.
In another aspect, the ring further includes an annular wall extending from the upper portion. The first annular flange is placed against the annular wall while the second annular flange is placed against the lower portion.
In another aspect, the sheath further includes a shoulder formed between a wide section and a slender section. The shoulder is provided around a portion of the ring between the annular wall and the upper portion of the ring. The slender section is provided around the annular wall. The wide section is provided around the ring. The first annular flange is formed at an end of the slender section. The second annular flange is formed at an end of the wide section.
Other objectives, advantages and features of the present invention will be apparent from the following description referring to the attached drawings.
The present invention will be described via detailed illustration of three embodiments versus the prior art referring to the drawings wherein:

The ring 20 is shaped like a cap. That is, the ring 20 is inverted U-shaped in
The tube 30 includes an upper portion, a lower portion and a middle portion. The diameter of the upper portion of the tube 30 is larger than that of the middle portion, and the diameter of the middle portion of the tube 30 is larger than that of the lower portion. The upper portion of the tube 30 is inserted in the restraining portion 28 of the ring 20 and hooked by the hooking portion 32 so that the tube 30 is kept with the ring 20.
The piston 40 is connected to the upper portion of the tube 30. The piston 40 extends through an aperture (not numbered) made in the restraining portion 28. The piston 40 is located out of the ring 20.
The packing 50 is provided around the tube 30. A upper face of the packing 50 is in contact with a lower face of the upper portion 22 of the ring 20. When the ring 20 is connected to an upper portion of a bottle (not shown), a gap between the lower portion of the upper portion 22 of the ring 20 and the upper portion of the bottle is sealed by the packing 50.
The sheath 60 is made of metal and provided with beautiful bright colors by anodization. The sheath 60 includes a first annular flange 62 formed at an upper end, a second annular flange 64 formed at a lower end, and a pattern 63 formed on an internal side. There is an angle between the sheath 60 and the first annular flange 62. Similarly, there is an angle between the sheath 60 and the second annular flange 64. The angle is about 90° to 120°.
The first annular flange 62 is placed against the upper portion 22 of the ring 20 and the second annular flange 64 is placed against the lower portion 24 of the ring 20 as the sheath 60 is provided around the ring 20. There is no need to use adhesive to attach the ring 20 to the sheath 60. The pattern 63 is configured corresponding to the skid-proof device 21. That is, the pattern 63 includes grooves for receiving the ribs of the skid-proof device 21 and ribs inserted in the grooves of the skid-proof device 21. Thus, the sheath 60 cannot be rotated relative to the ring 20.
The first annular flange 62 abuts against an annular portion of the upper portion 22 of the ring 20 while the second annular flange 64 abuts against the lower portion 24 of the ring 20. Thus, sheath 60 is kept on the ring 20. Moreover, the second annular flange 64 is a bent portion to prevent the sheath 60 from cutting a user.
