Description

Vacuum packaging container using packing table

The present invention relates to a vacuum packaging container using a packaging table, in particular, to enable the vacuum packaging of beddings and clothes that are not used according to the seasonal change using a common packaging table and can store the vacuum-packed article in a container It relates to a vacuum packaging container using a packaging table.

Beddings and clothing that are not used according to seasonal changes are stored in a separate space for a certain period of time. Such a storage requires a large storage space when the volume is large, and there is a problem in that the mold is damaged due to moisture or the reproduction of worms is damaged due to being stored in an exposed state from the air. Vacuum packaging has been proposed to store bulky items such as bedding and clothing in a narrow space and to prevent damage to the storage.

An example of a conventional vacuum packaging is a vacuum compression pack in which a fastener member is formed on an upper end of a packaging stand. This vacuum compression pack puts a bulky item and puts the suction tube of the vacuum cleaner on the top of the packing table so that the pressure is lower than the atmospheric pressure inside, so that the goods put into the plastic bag by the atmospheric pressure are compressed, and then the fastener member on the top of the packing table. Lock it so it is reduced to a smaller volume so that bulky items are stored in a minimum space.

These vacuum compression packs are not uniform in their compressed form and are in an irregularly compressed state, so if they are stacked several, they will have to fall to one side.

In order to solve this problem, Republic of Korea Utility Model Registration No. 20-326592 "Packing structure of the compression pack" (2003. 9. 2) has been proposed, which is shown in Figures 1 and 2. As shown, the packing structure of the compression pack is a pack member 60 having a storage space for accommodating a storage object, such as sleeping bags, clothing, and wrinkles 62 shrinkage and relaxation in the bellows type; A fastener member 63 is provided at the top of the pack member to open or close the storage space and to compress the pleats 62 while maintaining the interior of the storage space in a vacuum state. The packing structure of the compression pack has an open top and closed box shape with a lower end, and the pleats 62 are integrally connected to the upper end, and the pleats 62 are compressed to substantially pack the pack member 60. A case member 40 having a transparent window 41; And a lid member 50 capable of sealing the upper end of the case member 40 in a state in which the pack member 60 is embedded in the inner space of the case member 40 and having a handle 51. ; When accommodating an object to be stored in the storage space and compressing the pleats 62, the pleats 62 are shrunk while being guided by the case member.

The above invention is to be laminated and stored by compressing to a predetermined form without convex protruding into the upper and lower surfaces of the pack member, there is an effect that can be neatly stored these laminated pack members by the case member.

The above-described design also allows the article to be stored by locking the fastener member 63 after putting the suction tube of the fastener member 63 vacuum cleaner provided at the upper end of the pack member in the same manner as the aforementioned vacuum compression pack.

In the above vacuum packaging examples, a fastener member is installed at an upper end to compress and put a bulky article, and only a part of the fastener member is opened and a suction tube of a vacuum cleaner is inserted into the vacuum cleaner. Therefore, since the outside air is sucked between the suction pipe and the open space of the fastener member, the suction efficiency is lowered, which makes rapid suctioning difficult. In addition, noise is generated as the outside air is sucked into the pack member, and there is a troublesome handling process in which the suction tube of the vacuum cleaner is quickly removed to close the fastener member so as not to leak the vacuum. In addition, in such a state, there is a problem in that it is difficult to obtain a high vacuum state due to inflow of air from the outside.

In addition, the pack member of the packing structure of the compression pack is a wrinkled portion is formed, there is a problem that the fastener member is installed on the upper end is not easily available on the market and its price is expensive.

Another example of the conventional vacuum packaging is a vacuum compression pack having a separate air outlet for making the inside of the pack member into a vacuum state by using a suction tube of the vacuum cleaner, Korean Utility Model Registration No. 20-0356709 "Vacuum of the foldable packaging case Air vents "(July 8, 2004).

The invention is designed to compensate for the drawbacks of the suction efficiency reduction, noise generation, vacuum leakage, and inflow of external air when the vacuum state of the above-described vacuum packaging is made. The air outlet is integrally provided in a packaging case that can be folded. There is an effect to facilitate the discharge of air inside the case.

However, the above invention has a problem in that it is not easily available on the market and its price is expensive, as with the pack member of the packing structure of the compression pack described above. In addition, when the collapsible packaging case is broken, the vacuum is leaked and cannot be recycled. In addition, when the vacuum packaging is completed, its shape is relatively inconsistent, which makes it difficult to store it, which is a disadvantage in that storage is inconvenient.

The present invention is to solve the above problems, it is possible to use a commercially available low-cost packaging stand commonly available in the market, it is possible to compress the bulky article in a high vacuum state to conveniently compress to a smaller volume And, when storing a large amount of the purpose is to provide a vacuum packaging container that can be stored safely stacked on top of each other.

The present invention achieves the above object by allowing the package stand to be replaceably accommodated inside the enclosure formed to a certain standard, and compressing the package stand to a high vacuum state using a vacuum cleaner in the accommodated state.

The vacuum packaging container using the packaging table of the present invention as described above can be rapidly accommodated in a high vacuum state by compressing the vacuum cleaner by receiving the packaging table in the housing so that the packaging can be replaced. It can be compressed conveniently. In addition, the packaging can be replaced at any time, economical, and when stored, the storage is protected by the enclosure, so safe storage is possible. In addition, even when a large amount of storage, the enclosure can be stacked on top of one another to enable efficient storage.
