DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dripper used for straining regular coffee powder, black tea, green tea and the like, and more particularly, to a dripper which can be easily erected and used in a cup. The present invention relates to a disposable dripper that can be placed and fixed in a state where the dripper is displaced.

[0002]

2. Description of the Related Art Conventionally, when drinking and drinking regular coffee powder, black tea, green tea, etc. stored in cans, bottles, or packaging bags, there is no need to prepare or wash a strainer and it is easy to use. Accordingly, disposable drippers have been developed, for example, those disclosed in Japanese Utility Model Publication No. 2-23206 and Japanese Utility Model Publication No. 3-31238. Each of them is a dripper configured by attaching a funnel-shaped filter inside a foldable paper board, and erects the folded paper board, and the folded paper board. A dripper is placed and fixed on the cup wall using the protrusions, cuts, or cutouts provided in the cup, and a funnel-shaped filter filters regular coffee powder, black tea, green tea, etc., stored in cans, bottles, or packaging bags. By filling hot water into the funnel-shaped filter in this state, regular coffee, black tea, green tea and the like can be obtained in the cup.

However, each of the above-mentioned disclosures has a cylindrical shape having a triangular cross section.
No. 238 discloses a configuration in which a cross section does not have a wall surface forming one side of a triangle, and a protrusion at the upper portion of a half-fold portion is provided with a folding portion that is folded toward the filter.
The upright dripper can be placed and fixed on the cup wall without shrinking.By providing this folded part, the upright dripper can be prevented from shrinking naturally, Although a certain effect can be obtained in that the opening for pouring can be secured, it is necessary to pay attention when pouring hot water because the opening is originally small, and the weight of hot water as the hot water is poured Thus, there is a problem that the opening becomes smaller, and more careful attention is required.

On the other hand, the one disclosed in Japanese Utility Model Publication No. 2-23206 discloses a tubular dripper having a triangular cross section having three wall surfaces by erecting a folded paper board. The folding is enabled by a vertical folding curve provided on one of the three wall surfaces. For this reason, even when the folded paper board is erected, the wall surface having the vertical folding curve is subjected to a curling force due to the folding habit of the vertical folding curve. In order to prevent this, an upright supporting piece is perforated on a wall having a vertical folding curve so as to be freely bent, and when the folded paper board is raised to form a dripper, this upright supporting piece is bent vertically. Is controlled by bending the outer surface of the dripper to the outer side of the wall having the dripper. In comparison with the method disclosed in Japanese Utility Model Publication No. 3-31238, the dripper that has been erected on the cup wall in a more stable state. It can be placed and fixed. However, the upright support piece is in a free state, and may return to the original state depending on how to handle it, and the opening provided by raising the folded paper board may shrink. There is a problem that care must be taken when pouring boiling water.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above problems, and is a dripper that can be folded and can be easily erected during use. It can be placed and fixed on the cup wall surface in a state where it has been placed, and especially after being placed and fixed on the cup wall surface, the opening provided by standing up does not shrink, and it is a disposable type that can be used with confidence To provide a dripper.

[0006]

Means for Solving the Problems In order to achieve the above object, the present inventor has set forth a dripper according to the first aspect of the present invention, wherein a set of a cylindrical body having a rectangular cross section which is open in the vertical direction is provided. A bag-shaped filter having an opening on one side on the inner surface of the opposing wall is fixed and housed so as to have an opening on the upper side, and the upper edge of each of the other set of opposing walls of the cylindrical body is One end edge of each of the two fixing plates is connected to bendable, and the other set of opposing wall surfaces and the entire length of the fixing plate connected to the other set of opposing wall surfaces in the vertical direction. A dripper provided with creases over the two fixed plates and bent along the outer surface of the tubular body,
A cutout is provided at the other end of each of the fixing plates, and the cutout is inserted into the cup wall surface. With this configuration, the dripper can be folded and can be easily erected during use, and the dripper that has been erected can be stably mounted and fixed on the cup wall surface, and particularly mounted and fixed on the cup wall surface. Thereafter, the opening provided upright does not shrink, and can be used with confidence.

Are formed into a cylindrical body 50 having a rectangular cross-section having the front plate 2, the rear plate 4, and the side plates 3 and 5 as wall surfaces.
Is folded back to the outer surface side of the cylindrical body 50 by folding lines 31 and 32, and the notch 9 provided in the fixing plates 7 and 8 is inserted into the cup wall surface to stand on the cup as shown in FIG. In this state, it can be stably mounted and fixed, and becomes usable. In this state, regular coffee powder, black tea, green tea, and the like are filled in the filter 10 and a desired beverage can be obtained in the cup by pouring boiling water.

The cutout 9 is not limited to the shape shown in this embodiment, but may be any shape as long as it can be inserted into the cup wall surface and can be stably mounted and fixed. No problem. Further, the fixing portion 13 for fixing the filter 10 to the blank plate 1 'is not limited to the shape and position shown in the present embodiment, but may be the same as the blank plate 1'.
Any shape and position as long as the hot water is poured into the dripper 1 having the filter 10 filled with regular coffee powder, black tea, green tea, etc. It may be. Also, the shape of the knob 60 is not limited to the substantially semicircular shape shown in the figure, and any shape can be easily picked when the folded dripper 1 is raised. It does not matter.
