Description

[0001] The present invention relates to a container having antibacterial activity,

The present invention relates to a container having an antimicrobial activity function (for example, a water bottle, a water bottle, a plastic bottle, etc.), and more particularly to an antibacterial composition having an antibacterial activity, To prevent the propagation of various bacteria (eg, Escherichia coli, Coliform bacteria, Cholera bacteria, Typhoid bacteria, Paratyphoid bacteria, Staphylococcus aureus, Staphylococcus aureus, Diphtheria bacteria, Staphylococcus aureus, Fungi, etc.) And a method for producing a container having an antibacterial activity function.

As the environmental pollution becomes serious with the development of the industry, the pollution of the water quality by various germs is also becoming a big social problem. Such water pollution is leading to situations where users can not consume water without consent.

For this reason, a water purifier is basically installed in a residential space such as a general home or a workplace, and drinking purified water purified from tap water is generally used. Also, when the user leaves the residential area of a home or workplace, It is the case that they carry water containing purified water by a water purifier or purchase separate bottled water for drinking.

However, there is a limit to the amount of water that can be contained in a water bottle, and since it is difficult to purchase bottled water outdoors, such as mountains and rivers, it becomes almost impossible to obtain purified water when staying outdoors for a long time.

On the other hand, in the case of a water bottle (military water bottle) provided to the soldiers in the army as shown in Registration Practical Utility Model No. 20-0404234 (registered on Dec. 12, 2005), water is put into the water bottle before the training, There is no choice but to keep it for a long time. In this case, the water put in the water bottle often gets polluted.

Accordingly, there is provided a water container having a removable filter of Registration Practical Utility Model No. 20-0234144 (date of registration June 1, 2001) or a disinfecting device of a public utility model No. 20-2010-0005260 (published on 2010.05.24) In a water bottle, a portable water bottle having a removable filter or a sterilizing device is provided so that the user can drink purified water at any time in the open air.

However, in the above description, the use of the removable filter in the bucket has the inconvenience of replacing the filter from time to time.

In addition, in the case of the sterilizing apparatus, since the UV-LED must be installed as a sterilizing light source and the power must be supplied to the sterilizing apparatus, it is difficult for a soldier who needs a long time training to have a sufficient amount of battery (e.g., battery) In order to solve this problem, it is necessary to use a large-capacity battery, but in this case, the size of the water bottle is increased and the portability thereof is deteriorated.

In the case of military canteen, aluminum cantilever is manufactured and stored at present. However, in the case of aluminum cantilever, there is a disadvantage that it is expensive and heavier than manufacturing a canteen through injection molding.

DISCLOSURE Technical Problem Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a container made of a resin material containing an antibacterial composition having an antibacterial activity function to store potable water (e.g., water, It is possible to prevent the propagation of various bacteria such as Escherichia coli, Adeno bacteria, Cholera bacteria, Typhoid bacteria, Paratyphoid bacteria, Staphylococcus aureus, Staphylococcus aureus, Diphtheria bacteria, And to provide a container manufacturing method having an antibacterial activity function that enables the container to be safely made.
