Provided is a tea bag capable of improving production efficiency. SOLUTION: The left and right sides of a tubular packaging material made of a water-permeable material are folded inward to form a gusset, and the upper and lower open ends of the tubular packaging material and the upper and lower ends of the gusset are sealed to form a tea bag body. In addition, one end of the hanging string is fixed to the back side of the central portion of the one gusset.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention is a tea bag for green tea, black tea, coffee, etc., which folds flat when wrapping, expands the tea bag when drinking, and the components of the drinking material are quickly extracted into the hot water It is about tea bags.

[0002]

[Prior art]

 A tea bag in which a tea bag main body is formed in a triangular pyramid shape so that a large space is formed in a main body containing a drinking material is disclosed in Japanese Utility Model Laid-Open No. 6-71470.

[0003] However, this tea bag is formed in a triangular pyramid shape from the beginning using a packaging material that is not easily creased so as to form a space above the contents, for example, a fine mesh nylon packaging material. Therefore, even if you try to fold it flat, you cannot fold it thinly. Therefore, when this is stored in a packaging bag, not only does it become bulky, but there is a drawback that it cannot be stored in a good format.

As shown in FIG. 7A, this kind of triangular pyramid-shaped tea bag is made of a long tubular packing material 11 in which hanging strings 10 are fixed in advance at intervals. After welding and fusing between the upper and lower bag holders 12 by ultrasonic vibration, the upper and lower bag holders 12 are retracted, and the packaging material 11 is filled with a certain amount of potable material, and the packaging material 11 is filled. 7 is pulled downward by a certain length, and then, as shown in FIG. 7B, the bag retainer 12 is rotated by 90 ° in the horizontal direction and welded and blown in the same manner as described above.

[0005] Therefore, in the above-described continuous manufacturing apparatus for tea bags, bag holding means that repeats turning in the horizontal direction is required.

[0006]

[Problems to be Solved by the Invention] The present invention is intended to expand the tea bag so that the components of the drinking material can be quickly extracted into the hot water, and can be packaged without bulk and in good shape. The aim is to provide a tea bag that simplifies equipment and improves production efficiency.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the tea bag of the present invention forms a gusset by folding the left and right sides of the tubular packaging material made of a water-permeable material inward, and forms the gusset with the upper and lower opening ends of the tubular packaging material. The tea bag body is formed by sealing the upper and lower ends of the gusset, and one end of the hanging string is fixed to the back of the central portion of the one gusset.

[0008] Since the present invention has the above-described configuration, a hanging string fixed to one of the gussets is held, and when the tea bag body is hung, the gusset on the upper side is pulled up by the hanging string, developed, and hung. When the thread is shaken up and down, the lower gusset expands due to the weight of the drinking material, and the entire tea bag body swells greatly. When this is put in a bowl and poured with hot water, the hot water easily penetrates into the drinking material, and the components are immediately extracted. In the case where the packaging material is a hard material, if the packaging material is slightly shaken in hot water, the drinking material swells, the tea bag body is largely expanded, and the components of the drinking material are quickly extracted into the hot water.

[0009]

[Embodiment of the invention]

 For the tea bag body of the present invention, cloth, non-woven cloth, and the like are used in addition to the fine mesh nylon packaging material. Since the hanging string is used to extend the gusset by suspending the main body, the hanging string may be tape-shaped and may be of any length. Suspensions may also be secured to both gussets.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. 1 and 6 are examples of a tea bag. FIG. 1 is a perspective view of a folded state, FIG. 2 is a cross-sectional view taken along line AA shown in FIG. 1, FIG. 3 is a perspective view of an expanded state, and FIG. FIG. 5 is a cross-sectional view taken along the line BB shown in FIG. 3, and FIG. 6 is an explanatory view of the manufacturing process.

Reference numeral 1 in the figure denotes a tea bag main body formed of a fine mesh nylon packaging material 2, and the left and right sides of the nylon tubular packaging material 2 are folded inward to form a gusset 3. Further, the upper and lower open ends of the cylindrical packaging material 2 and the upper and lower ends of the gusset 3 are sealed by welding portions 4.

Reference numeral 5 denotes a suspension string having one end fixed to the center part deep side of one gusset 3 and a tag 6 attached to the other end.

As shown in FIG. 6, the above-mentioned tea bag is formed by folding the left and right sides of the tubular packaging material 2 inward to form a gusset 3 and hanging the gusset 3 at a certain distance behind the gusset 3. One end of the thread 5 is fixed, and an intermediate position between the suspending thread 5 and the suspending thread 5 is flatly sandwiched by upper and lower bag holders 7, and the space between the bag holders is welded and cut by a cutting device using ultrasonic vibration. After that, the fixed amount of the drinking material 8 is filled, the tubular packaging material 2 is pulled out downward, the intermediate position between the hanging strings 5 is sandwiched by the bag retainer 7 in the same manner as described above, and is welded and melted to be continuously cut. To manufacture.

[0014]

[Effect of the invention]

 The tea bag according to the present invention is embodied in the form described above, and has the following effects.

According to the present invention, the tea bag can be widely deployed by pulling the hanging thread, and the components of the drinking material can be quickly extracted into the hot water.

According to the present invention, even if the tea bag body is formed by a fine mesh nylon packaging material, the upper and lower ends of the gusset are sealed by the welded portions, so that the gusset is packaged in a folded state and in a good shape. I can do it.

Further, unlike the case of a triangular pyramid-shaped tea bag, there is no need to rotate the bag holder, so that there is an effect that the manufacturing apparatus can be simplified and the production efficiency can be improved.
