Interior anchor structure for a vacuum preserving container
An interior anchor structure for a vacuum preservation container has a closed and resilient pouch filled with gas located therein. When the preservation container holds a preserving article and is vacuumized, the resilient pouch inflates because of the interior pressure of the preservation container decreases. The elasticity and flexibility of the resilient pouch may be deformed to squeeze and hold the preserving article securely in a still manner without shaking and damaging.
The present invention relates to an interior anchor structure for a vacuum preserving container and particularly to an interior anchor structure for holding an article in a preserving container through a closed and deformable resilient pouch filled with gas and inflatable due to air pressure variation.
BACKGROUND OF THE INVENTION Damp-resistant, mold-resistant and corrosion-proof techniques are commonly used in people's daily life. Refer to
The conventional technique mentioned above has been widely used for preserving foods, musical instruments, electronic devices, optical equipment, and other articles needed to be protected from damping. While the conventional technique mentioned above can protect articles from being damaged by damping, mold infliction or corrosion, the articles held in the preserving container 1 might hit the interior of the preserving container 1 when the container is moved by users and result in damage. To remedy this problem, some preserving container 1 has a pliable padding matching the article to be held embedded in the container as a lining to reduce the possible impact when the preserving container 1 is moving. It still cannot fully overcome the problem. Moreover, when the article and the padding are fitted tightly with a too small gap or no gap, the article is difficult to be removed from the container, and the article might be damaged if it is removed forcefully. The damage of the preserving article caused by shaking still cannot be totally eliminated. Hence there is room for improvement.
SUMMARY OF THE INVENTIONTherefore, the primary object of the invention is to provide an anchor structure to prevent articles held in a preserving container from being damaged by shaking.
Another object of the invention is to provide an anchor structure adaptable to a preserving article of any shape.
The preserving container according to the invention includes a plurality of closed and resilient pouches filled with gas in the interior, a lid and a chest. The chest has a housing compartment. The lid can cover and close the chest tightly. The preserving container further has a vacuum apparatus to vacuumize the housing compartment. The housing compartment can hold preserving articles. According to Boyle's law, when a fixed amount of gas at a constant temperature, its volume and pressure form an inverse ratio, indicated by an equation of PV=K (where P is the pressure, V is the volume and K is a constant). Hence when the vacuum apparatus starts vacuumizing, the volume of the resilient pouch grows gradually as the pressure of the housing compartment decreases. Hence the resilient pouch can squeeze and hold the article to prevent the article from shaking and damaging.
The resilient pouch is made from an elastic material and is flexible, and may be deformed according to the shape of the preserving article, thus can hold and anchor different shapes of preserving articles.
The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
Please refer to
Take a violin as an example of the preserving article to be held. A housing space for holding the violin is reserved in the housing compartment 13. The housing compartment 13 has an inner wall lined with a closed and resilient pouch 20 filled with gas and formed in an annular fashion around the housing compartment 13. Once the violin is held in the housing compartment 13, and the housing compartment 13 is vacuumized, according to Boyle's law, the resilient pouch 20 is inflated to squeeze the violin and deformed according to the shape of the violin. Thus the resilient pouch 20 presses the violin in various directions without creating damage, and the violin is securely held in the housing compartment 13 without shaking and damaging even if the preservation container 10 is moved. When the vacuum condition of the housing compartment 13 is released, the resilient pouch 20 deflates, and user can easily remove the violin from the housing compartment 13.

The anchor board 31 is distributed on the entire bottom of the housing compartment 13 with the opening 33 directing upwards. A portion of the anchor board 31 may be removed according to the requirement for holding the preserving article. In this embodiment the preserving article is a violin to serve as an example. In practice, users can configure by themselves according to the requirement of different preserving articles. Referring to
In the embodiments set forth above, the resilient pouch 20 is made from rubber or the like, preferably Thermoplastic Ployurethane (TPU). TPU is an environment-friendly material without toxicity. It also is an elastic polymer resistant to wearing, stretching, and low temperature without cracking. Hence the resilient pouch 20 of the invention can hold the preserving article securely in the preservation container 10 in a still manner without damaging, and is adaptable to different shapes of preserving articles.
