Description

[Detailed explanation of the invention] [Industrial application field] This invention can be used for example in tea packs, dashi packs,
This invention relates to a pack used as a decoction pack for crude drugs.

[Prior Art] Figs. 7 to 11 are views showing a conventional pack of this kind, as disclosed in, for example, Japanese Utility Model Application Publication No. 59-138568, in which Fig. 7 is a front view and Fig. 8 is a rear view. 9 is a sectional view taken along the line - in FIG. 7, FIG. 10 is a partially cutaway rear view showing the state of use, and FIG. 11 is a sectional view taken along the line - in FIG. 10. In the figure, 1
is a water-resistant flake made of, for example, nonwoven fabric, paper, cloth scraps, etc. This water-resistant thin piece 1 is folded in half to form both sides of the flat bag body, and one of the folded ends of the both sides and the mating end located on the opposite side are turned outward from the front side. Fold back cover part 1
The bag body shown in FIGS. 7 to 9 has an opening 3 formed at the mating side end by forming a seal 2 on both the left and right edges of both sides together with the cover part 1a. Configure. 4 is a filler, such as tea, dashi powder, or a decoction of crude drugs.

After pouring tea 4 through the opening 3 of the bag in the state shown in FIGS. 7 to 9, the cover portion 1a is turned over to the opposite side as shown by the arrow 5 in FIG. 9 to cover the opening 3. When the lid is closed, a tea pack is formed as shown in FIGS. 10 and 11. This is eluted using the conventional method, that is, placing the bag in a container and soaking it in boiling water.

[Problems to be solved by the invention] Since the conventional packs were constructed as described above, there was a problem in that it was very difficult to take them out of the container after putting them in hot water and boiling them for a certain period of time.

This invention was made to solve this problem, and the purpose is to obtain an inexpensive pack that can be easily and safely removed from the container after boiling.

[Means for Solving the Problems] The pack according to this invention is provided with a take-out string that is wrapped around the cover part 1a and fixed at both left and right ends by seals 2, and when the cover part 1a is inverted and covered. The string is exposed to the outside of the bag.

[Function] In this invention, when boiling in the container, a part of the removal string can be left outside of the hot water, so that the bag can be removed from the container by pulling this string after boiling.

[Embodiment of the invention] An embodiment of the invention will be described with reference to FIGS. 1 to 4. Figure 1 is a front view, Figure 2 is a sectional view taken along the line - in Figure 1, Figure 3 is a partially broken rear view showing the state of use, and Figure 4 is a sectional view taken along the line - in Figure 3. The same reference numerals are given to the same or equivalent parts as those of the conventional one, and the explanation thereof will be omitted. In the figure, reference numeral 6 denotes a strip-shaped take-out string made of unstretched polyester, which is wrapped by the cover portion 1a and fixed at both left and right ends by seals 2.

If the removal string 6 is placed inside the cover part 1a as shown in FIGS. 1 and 2, when the cover part 1a is reversed in the direction of the arrow 5, as shown in FIGS. 3 and 4, When in use, the take-out string 6 is exposed to the outside of the bag, so when the bag is placed in a container and boiled, the center of the take-out string 6 is pulled and stretched to extend it out of the container. In this way, after boiling, the bag can be easily and safely removed from the container by pulling the center of the string 6. If this removal string 6 is inserted between the water-resistant thin pieces 1 when folded, the thin pieces 1 can be attached to the seal 2.
Since both ends 6a of the string 6 are fixed at the same time, the removal string 6 can be easily attached to the bag, and no special manufacturing process is required for attaching the string 6.

If the take-out string 6 is formed of a band of unstretched polyester in this way, the unstretched polyester band 6 will be stretched to 3 to 4 times the length during use, and the center of the string will be stretched to the outside of the container. It becomes easier to pull out.
That is, even if the length spans between the seals 2 and 2 during manufacture, it will be three to four times as long during use, so no special process is required for manufacture and it is easy to use.

In the above embodiment, the unstretched polyester removal string 6 was used, but as shown in FIG. 5, a simple long string 6A may be folded and stored in the cover portion 1a. In this case, as shown in FIG. 6, the rectangular seal 6B can be elongated, making it easier to pull it out of the container.

[Effects of the invention] As described above, this invention has the effect that it can be easily and safely taken out of the container after boiling using the removal string, and it is also inexpensive.

Claims (1)

[Claims for Utility Model Registration] The water-resistant thin piece 1 is folded in half to form both sides of a flat bag body, and one of the folded side ends of both sides and the mating side end located on the opposite side. is folded outward to form a cover part 1a, and seals 2 are applied to both the left and right edges of both side surfaces together with the cover part 1a, thereby forming an opening 3 at the mating side end. 3, the pack is formed into a bag by inverting the cover part 1a to the opposite side and covering the bag with a take-out string that is wrapped by the cover part 1a and fixed at both left and right ends by the seals 2. A pack characterized in that the string is provided outside the bag body when the cover part 1a is reversed as described above.
