Description

Screw End for Can Container and Reelectric Can Container Using It {SCREW END FOR CAN AND RESEALABLE CAN USING THE SAME}

The present invention relates to a screw end used in a metal can container and a can container using the same.

1A and 1B are front views of a conventional can container 100. Conventional can containers generally have a structure in which the sealing end 110 shown in FIGS. 2A and 2B is coupled in a wound manner to only the upper end of the can body 120 or both the upper end and the lower end to seal the contents therein. consist of. 3A and 3B are front views of the can body 120 shown in the state where the sealing end 110 located at the upper end of the conventional can container 100 is removed. Extraction of contents from the can container 100 may be performed by cutting a sealing end 110 positioned at an upper end of the can body 120 using a tool, or at a predetermined portion of the sealing end 110. It is generally performed by molding the opener 112 to remove it by hand.

While the can container as described above has excellent preservation of contents such as beverages, unlike the bottle or glass bottle with a cap in the beverage container, there is no so-called resealability that can be sealed again after opening the container. The beverage can is inconvenient to carry and there is a problem that gas components dissolved in the beverage are released into the atmosphere, which may alter the taste of the beverage and allow foreign substances to enter the opened inlet. This problem has been a barrier to the expansion of can containers.

In order to compensate for this problem, a can container (see FIGS. 4A and 4B) of a can body and a screw-type bottle cap unit has been developed for the purpose of giving re-electricity to can containers. Since the facility is not available, it is inevitable to invest in large-scale facilities for new production lines according to new product design, and even if the existing production line is remodeled, it is inevitable to reduce sales due to the production loss accompanying a long construction period. There is a problem in that introduction is actually difficult.

In addition, since the capacity of the can container depends on the height and diameter of the can container, and the shape of the body, the can container and the screw bottle-type can container are used to change or modify the manufacturing facilities for the standardized new capacity can container. There is a problem that large-scale investment is inevitable, and it takes a long time to establish the manufacturing technology. For this reason, the can container of the can body screw bottle-type integrated commercially available is only a few species. Therefore, the can body of the can body and the screw-type bottle cap is limited in the development of a new product having various capacities.

Therefore, it is possible to increase the added value of can containers by providing reconstruction to can containers, and to reduce the burden on new facility investment by using all or part of existing can containers production lines as they are. Is requested.

It is an object of the present invention to provide a canister screw end and a can container using the same can be used as it is to provide re-electricity to the can container, as well as the existing production equipment.

112: opener 120: can body

130: screw end 132: thread

134: curl 136: middle part

140: cap 142: thread

The gist of the present invention for achieving the above object is as follows.

(1) A screw end for a can container, which is designed such that the upper end is screwed into a bottle shape to be screwed with a cap, and the lower end is formed into a curl shape to be coupled to the can body in a winding manner to impart reelectricity to the can container.

(2) The can container containing the screw end of said (1) description.

Hereinafter, with reference to the accompanying drawings will be described in detail the contents of the present invention.

5 is a view showing a can container 100 including a screw end 130 according to the present invention. Can container 100 according to the present invention is the screw end 130 is located at the inlet of the container is coupled to the can body 120 in a winding manner, the upper end of the screw end 130 sealing cap 140 is screwed Recombination is given by being combined with.

The can body 120 is a conventional container filled with the contents of the beverage after being combined with the screw end 130 according to the present invention in the conventional winding method using the conventional can body shown in Figures 3a and 3b It is preferable to make it possible to use the production facilities for a conventional can body and a cap as it is by sealing with a cap and the like to impart reelectricity to the can container.

6 is a front view of the screw end 130 according to the present invention. The upper end of the screw end 130 has a bottle shape, and a thread 132 is formed along the outer wall thereof to be screwed with the cap 140. The lower end of the screw end 130 is formed with a curl 134 may be coupled to the can body 120 in a winding manner. The middle portion 136 of the screw end 130 has a dome shape and both ends are open. Optionally, the middle portion of the screw end may be planar in spite of what is shown in FIG. 6. In this case, the lower surface of the upper end of the bottle shape is placed on the same plane as the middle of the planar shape.

The diameter d1 of the upper end of the screw end 130 and the diameter d2 of the lower end may be appropriately combined and used depending on the properties of the contents contained in the container and drinking properties to satisfy various consumer needs, and is not particularly limited. Does not. Tables 1 and 2 illustrate diameters d1 and d2 of the upper end and the lower end of the screw end 130 that may be applied to the can body 120 and the cap 140 which are conventionally used.

In addition, the height (h) of the screw end can be appropriately added or decreased depending on the use of the container and the aesthetics of the entire container, and is not particularly limited.

FIG. 7 is a cross-sectional view of the cap 140 coupled to the screw end 130 of FIG. 6 to seal the container contents. The inner wall of the cap is formed with a thread 142 corresponding to the thread 132 of the upper end of the screw end 130. The material and shape of the cap 140 is not limited.

The above description relates to specific embodiments of the present invention. The above embodiment according to the present invention is for the purpose of explanation only, it should be understood by those skilled in the art that various changes and modifications can be made without departing from the spirit of the present invention. For example, the screw end according to the present invention can be applied to a metal can container among the packaging containers used in the food and beverage industry, regardless of the material, size and shape of the can container, the can end the sealing end after filling the beverage in the can container It can be applied to all conventional can containers manufactured by sealing the body in a double winding manner. The material can be aluminum or steel, and the container capacity is 100-1000 ml, and can be applied to all conventional can bodies without two-piece or three-piece reelectricity in form.

Therefore, all such modifications and changes are to be understood as falling within the scope of the invention disclosed in the utility model registration claims or their equivalents.

The screw end according to the present invention can provide convenience for carrying and using the can container to the general consumer by providing re-electricity to the can container, while using the existing production equipment for the can body and cap as it is and screw end Only a small investment in some of the equipment required for the manufacture and winding of cans with the can body can achieve the purpose of regenerating cans. In addition, the use of the screw end according to the present invention is advantageous in terms of reducing the new investment and the stability of the production line due to fewer new replacement parts of the equipment.

In addition, since the screw end according to the present invention can be applied to dozens of different kinds of can containers having a new capacity in the form of simply winding together with all kinds of can bodies already existing or to be developed in the future, general consumer and beverage production The company can expand its options and contribute significantly to the expansion of refillable can containers.
