Patent Application
20130287472
The present invention relates to a container, and more particularly to a portable cosmetic container that can safely secure the substance therein to avoid spraying when a user opens the container.
As can be seen in
However, once the tubing unit 10 is sealed, the air in the receiving chamber 11 is compressed, so the air pressure of the air space 13 is greater than one atmospheric pressure when the sealing process is completed. The user can break the tubing unit 10 from a crease 15 when the user would like to use the substance 12 in the receiving chamber 11. Since the pressure in the air space 13 is greater than one atmospheric pressure, when the tubing unit 10 is broken from the crease 15, the pressure in the air space 13 releases to reach a steady state with an environment outside. Meanwhile, the pressure in the air space 13 that is greater than one atmospheric pressure may cause the substance 12 to randomly spray out, and cause some waste of the substance 12 as well.
U.S. Pat. No. 5,515,991 to Heitland discloses a cosmetics container that a receiving segment with a planar bottom and which is sealable by an air-hermetic main cover as shown in
U.S. Pat. Pub. No. 2011/0299911 discloses a cosmetic container having a container main body, a moving part, a middle cylinder part, and an application body. The container main body houses a cosmetic. When the moving part is positioned at a first stopping position, the closing part of the discharge cylinder closes the insertion hole of the middle cylinder part and seals the cosmetic. When the moving part is moved from the first stopping position to a second stopping position separating in the axial direction, the discharge cylinder protrudes by a predetermined length from the end face of the insertion hole and exposes the slit of the discharge cylinder. Thus, a user can visually confirm the condition that the cosmetic can flow out to the outside through the slits, the inside of the discharge cylinder, and the opening part. However, similar to Heitland, the cosmetic may randomly spray out if the air pressure is greater than one atmospheric pressure when the cosmetic is sealed. Therefore, there remains a need for a new and improved structure of the cosmetic container that can overcome the problems stated above.
The main object of the present invention is to provide a portable cosmetic container, and when a user opens the container, substance in the container would not spray out.
In one aspect, the portable cosmetic container may include a tube that has a sealed receiving space inside, and the receiving space has substance that partially fills the receiving space, so that there remains an air space whose air pressure is less than one atmosphere pressure after the air is being extracted, namely a negative pressure status. A crease is formed at one end of the receiving space of the tube, so the tube can be easily broken from the crease to form an opening.
In one embodiment, the receiving space in the tube has an open end, and a bottom portion of the receiving space has a crease, so that the tube can be broken from the crease to form an opening from the bottom of the receiving space. The substance can be liquid, paste or powder in the receiving space. The negative pressure is formed when the air is extracted from the receiving space. The opening of the receiving space can be sealed to form a sealed receiving space in which the substance partially fills the receiving space, and the air pressure in the receiving space is still less than one atmosphere.
Therefore, the substance can be sealed in the receiving space, and when the user breaks the tube from the crease, the substance can be poured out easily. Namely, the substance can be safely kept in the receiving space until the user break the tube, so it is convenient for the user to carry without concerning that the substance may unexpectedly come out. More importantly, when the tube is broken from the crease, the negative pressure (outside pressure is higher than the pressure in the receiving space) in the receiving space will keep the substance in the receiving space until the pressure reaches a steady state, so that the substance in the present invention will not randomly spray out when the tube is broken by the user.

The detailed description set forth below is intended as a description of the presently exemplary device provided in accordance with aspects of the present invention and is not intended to represent the only forms in which the present invention may be prepared or utilized. It is to be understood, rather, that the same or equivalent functions and components may be accomplished by different embodiments that are also intended to be encompassed within the spirit and scope of the invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this invention belongs. Although any methods, devices and materials similar or equivalent to those described can be used in the practice or testing of the invention, the exemplary methods, devices and materials are now described.
All publications mentioned are incorporated by reference for the purpose of describing and disclosing, for example, the designs and methodologies that are described in the publications that might be used in connection with the presently described invention. The publications listed or discussed above, below and throughout the text are provided solely for their disclosure prior to the filing date of the present application. Nothing herein is to be construed as an admission that the inventors are not entitled to antedate such disclosure by virtue of prior invention.
Referring to
After the tube 20 is sealed, the substance 22 is retained in the receiving space 21, so the tube 20 is portable without the concern of leaking. Also, it is convenient for the user to break the tube 20 from the crease 23 to pour the substance 22 out. More importantly, as stated above, when the user breaks the tube 20 from the crease 23, the air outside the tube 20 will keep the substance 22 in the receiving space 21 because the air pressure outside is greater than that in the receiving space. Namely, the receiving space 21 has a “negative pressure,” so that the air outside the tube 20 moves towards the direction of the opening of the tube 20 to prevent the substance 22 from suddenly spraying out.
As illustrated in
In another embodiment shown in
In another aspect as shown in
It is noted that even though the air pressure may increase when the opening of the receiving space 21 is sealed in step 604, the air pressure can still remain negative if more air has been extracted in step 603. Thus, when the user breaks the portable cosmetic container from the crease 23, the substance 22 will be kept inside the receiving space 21 to prevent the substance 22 from spraying out therefrom.
Referring to
The substance 22 in the present invention may include, but not limited to liquid medicine used for wounds in a family, such as hydrogen peroxide solution, merbromin solution, acrinol solution, methylrosaniline chloride solution, and providon solution. The substance 22 can also be maintenance cosmetics such as cleansing water, nail polish, and phytoncid.
In a further embodiment, the substance 22 can even be chemicals such as casein glue, urea formaldehyde glue, phenol formaldehyde glue, formaldehyde resin glue, acid-vinyl acetate rubber, and nitrocellulose glue. In still further embodiment, the substance 22 can be powder drugs or cosmetics, such as sulfa drug having anti-bacteria function or other appropriate powder drugs.
Having described the invention by the description and illustrations above, it should be understood that these are exemplary of the invention and are not to be considered as limiting. Accordingly, the invention is not to be considered as limited by the foregoing description, but includes any equivalent.
