Patent Application
20210316936
The present invention relates to a coaxial container, and more particularly to a coaxial container for dispensing a tubular product.
According to US Patent publication No. 2007/0059088, a conventional lipstick box structure is disclosed, however, following problems can be found in its actual application: The positioning piece 13 cannot provide a full circle of support, so the rotating base 11 is still tilled after assembly.
In addition, U.S. Pat. No. 5,842,803 discloses another conventional lipstick box structure, however the following problems still exist in its actual application: 1. The ribs 114, 14a, 14b, 14c, 14d cannot provide a full circle of support. 2. Each rib 14, 14a, 14b, 14c, 14d is made of the same material, so it cannot form a different inner and outer resistance force after assembly which causes poor concentricity. 3. The ribs 14, 14a, 14b, 14c, 14d are provided with a fixed structure, which provides poor resistance.
Therefore, it is desirable to provide a coaxial container for dispensing a tubular product to mitigate and/or obviate the aforementioned problems.
An objective of present invention is to provide a coaxial container for dispensing a tubular product, which is capable of improving the above-mention problems.
In order to achieve the above mentioned objective, a coaxial container for dispensing a tubular product has an inner tube connected to a rotating base allowing the inner tube and the rotating base to rotate relatively. A plurality of elastic latches are arranged in a full circle and disposed on a bottom portion of the inner tube connected to the rotating base, each elastic latch has a harder and thicker first potion and a softer and thinner second potion, and the first potion of the elastic latch is capable of making contact with the inner tube.
Other objects, advantages, and novel features of invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
First, please refer to
In addition, the sleeve 30 is configured to match a cover 31.
With the structure of the above specific embodiment, the following benefits can be obtained: With the resistance provided by a full circle of the elastic latches 13, the coaxial container can be operated more smoothly. Since each elastic latch 13 has the harder first potion 131 and the softer the second potion 132, after the assembly of the inner tube 10 and the sleeve 30, the first potion 131 with stronger resilient force forms a full circle of resistance against the inner wall of the sleeve 30, and the bent-back second potion 132 is used as an auxiliary support, which makes the elastic latches 13 to have a better bearing strength and improve the concentricity between the inner tube 10 and the sleeve 30 for smooth operation. Furthermore, with the support provided by the bent elastic latches 13, there is no need to fill or apply any lubrication oil between the inner tube 10 and the sleeve 30, which allows a safe, hygiene and convenient assembly.
Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of invention as hereinafter claimed.
