Description

[Technical field]

[0001] The present invention relates to a foaming member for foaming carbonated drinks such as beer and cola when they are poured from a container. [Background technology]

[0002] When carbonated beverages such as beer are poured into a drinking container such as a cup, good foaming is preferred. Good foaming refers to the formation of fine, uniform, so-called creamy foam when poured. Such foaming function is realized in commercial beer servers, but commercial beer servers have a large and complex structure, making it difficult to provide them at a low price, and maintenance work such as cleaning is also troublesome. For this reason, a method of attaching a whisk to a beverage can has been proposed, for example, as in Patent Document 1. These whisks are designed to produce fine foam by promoting gasification of saturated gases in beverages such as beer using air contained in the pores of porous ceramic.

[0003] Furthermore, Patent Document 2 discloses a cap to be attached to a can, which has a paper part with numerous air holes in the area facing the opening of the can, and it is said that when the beverage poured from the opening comes into contact with the paper part, fine bubbles are generated.

[0004] [Patent Document 1] JP 2002-332052 A [Patent Document 2] JP 2007-297129 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, the ceramic foaming dispenser described in Patent Document 1 has problems such as the ceramic being prone to breakage, the structure being still complicated, and the cost being high. Also, the cap in Patent Document 2 has problems such as poor foaming efficiency because the opening and the paper part are too close to each other, and the spout from the cap and the opening are on opposite sides, making it difficult to completely pour out the beverage.

[0006] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a foaming member that has a simpler structure, is easier to pour, and is low cost. [Means for solving the problem]

[0007] One aspect of the present invention for solving the above problems is a foaming member that is arranged at one end of a spout side of a storage container for storing a carbonated beverage and promotes foaming of the carbonated beverage, The device has a fixing part that can be fixed to one end of the container on the spout side, and a foaming part that is connected to the fixing part and foams the carbonated beverage while flowing down in contact with the surface of the carbonated beverage, The angle between the center line of the foaming portion in the width direction and the opening surface of the spout is 80° or more and 170° or less. and The fixing portion is provided at a portion where the user holds the container when pouring the carbonated drink. The foaming member is characterized by the above.

[0008] When the carbonated beverage is poured from the spout and flows down through the foaming part, it flows down while contacting the surface of the foaming part that is set at a specified angle to the opening face of the spout, which promotes foaming and allows the beverage to be poured with good foam.

[0009] In the foaming member, it is more preferable that the angle between the center line in the width direction of the foaming portion and the opening surface of the spout is 100° or more and 130° or less. It's small and easy to pour.

[0010] In the foaming member, it is preferable that the surface of the foaming portion is made of a material having a fine uneven structure, which makes foaming more likely to occur.

[0011] In the foaming member, the member having the fine uneven structure is preferably filter paper or nonwoven fabric, or surface-roughened paper, resin film or resin sheet. The uneven structure is dense and uniform, easy to foam cleanly, easy to obtain, and low cost.

[0012] It is preferable that the foaming member further has a pocket portion for the carbonated beverage to accumulate in. When the container is turned upright after pouring, the beverage remaining in the foaming portion accumulates in the pocket portion, so that the beverage does not leak out to the bottom side of the container.

[0013] In the foaming member, it is preferable that the foaming portion is curved or bent in the width direction so as to be concave toward the surface side. When the foaming portion is attached to one end of the spout side of the storage container, the foaming portion is curved or bent in an outwardly convex shape along the side surface of the storage container, making it difficult to deform and preventing the poured beverage from spilling.

[0015] The foaming member has a fixing portion provided at a portion where a user holds the container when pouring a carbonated beverage. When holding the container, the foaming member can be held at the same time, no special member is required for fixing, and the position of the foaming member can be easily adjusted.

[0016] In the foaming member, it is preferable that the foaming portion is spaced from the spout of the container by 5 mm or more, which increases the falling speed of the beverage and makes it easier for foaming to occur.

[0017] Another aspect of the present invention is a method for foaming a carbonated beverage, in which a fixing portion of the foaming member is fixed to one end of a spout side of a container for storing a carbonated beverage, and the carbonated beverage is poured from the spout, brought into contact with the surface of the foaming portion of the foaming member, and allowed to flow down while foaming, and then injected into a drinking container. Effect of the Invention

[0018] According to the foaming member of the present invention, when the carbonated beverage poured from the spout of the storage container flows down the foaming section, it comes into contact with the surface of the foaming section while flowing down, thereby promoting foaming and allowing the beverage to be poured out with good foam.

[0020] Hereinafter, the embodiments of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments described below. In addition, in the embodiments shown below, technically preferable limitations are imposed for carrying out the invention, but these limitations are not essential requirements for the present invention.

[0021] Fig. 1 is a development view of one embodiment of the foaming member of the invention. The foaming member 10 has a belt-shaped fixing part 12 for mounting on the spout side end of a carbonated beverage storage container, and a tongue-shaped foaming part 11 for guiding the carbonated beverage poured from the spout into a drinking container while promoting foaming. The fixing part 12 and the foaming part 11 are connected together by a connecting part 13 to form a single unit. As beer is a typical example of a carbonated beverage, the following description will be given assuming that it is beer.

[0022] A filter paper 14, which is a member having a fine uneven structure, is attached to the surface of the foaming portion 11, i.e., the surface along which the poured beer flows down. The filter paper 14 can be attached by appropriately adopting a known adhesion method. The member having a fine uneven structure is not limited to filter paper, and any material having a fine uneven structure formed on the surface can be suitably used. For example, paper other than filter paper, nonwoven fabric, resin film or sheet with a roughened surface can be exemplified. Filter paper is particularly preferred because it has a dense and uniform uneven structure formed on its surface, is easily available, has good processability, and is inexpensive.

[0023] The foaming portion 11 is also curved in the width direction, with the direction of the arrow A as the width direction, so that the surface side is concave and the center line 16 is the bottom. The center line 16 may be bent as a fold. A plurality of folds may be provided other than the center line 16. This makes it difficult for the beer to spill to the side when it is allowed to flow down. The length from the edge to the tip of the beer can when attached to the beer can in the direction perpendicular to the width direction of the foaming portion 11, i.e., in the direction in which the beer flows down (length L shown in FIG. 2), is preferably 30 to 80 mm, more preferably 40 to 60 mm. If it is too short, the foaming effect will be weak, and if it is too long, it will be difficult to handle and will be easily deformed.

[0024] The fixing part 12 is in a belt shape so that it can be wrapped around the end of the spout side of the beer can and fixed. The fixing part 12 may have a fold 15 so that it can be folded and stored easily. FIG. 2 is a side view of the foaming member 10 attached to the end of the surface 101 side of the beer can 100 where the spout is provided. FIG. 3 is an explanatory diagram of how canned beer is poured. The end of the spout side of the beer can 100 often has a rim 106 that bulges outward slightly around it, and the fixing part 12 is prevented from coming off by being hooked on the rim 106. Therefore, one side of the fixing part 12 is corrugated to make it easier to hook. In order to wrap the fixing part 12 around the beer can and fix it, for example, an adhesive seal 17 may be provided on one end of the fixing part and then pasted on the end on the opposite side, or the present invention is not limited to this. For example, a slit that can be engaged with each other may be provided on both ends, or an adhesive layer may be provided on the surface of the fixing part 12 that contacts the beer can 100 and pasted on the beer can 100. When the foam member is made of resin, it may be bonded by thermocompression.

[0025] The materials for the main body of the foam section 11 to which the filter paper 14 is attached, the connecting section 13 connected to the foam section 11, and the fixing section 12 are not particularly limited as long as they are water-resistant, flaky materials and can be appropriately selected from, for example, plastic sheets, cardboard, synthetic paper, laminated paper, metal foil, rubber sheets, wood, etc.

[0026] When the foaming member 10 is attached to the beer can 100, the connecting portion 13 is folded back outward relative to the beer can 100, and the foaming portion 11 is folded back again and attached. This makes it easier to adjust the angle θ between the center line 16 of the foaming portion 11 and the opening surface of the spout (which is substantially the same as the surface 101 where the spout is provided), and the recessed area between the connecting portion 13 and the foaming portion 11 can be used as a pocket portion 18. The angle θ is 80° or more and 170° or less as shown in Figure 2, and is more preferably 100° or more and 130° or less, since it makes it easier to pour the poured beer.

[0027] When opening the pull tab of the beer can 100 and pouring beer from the spout 102, first, normal liquid beer is poured into about 70% of the drinking container 200 without attaching the foaming member 10, forming a liquid beer layer 104. Next, the foaming member 10 is attached, and the remaining 30% is poured out. At this time, the poured out beer 103 falls onto the surface of the foaming part 11, flows down while contacting the surface, and foaming is promoted by the filter paper 14 attached to the surface, turns into fine bubbles, and is poured into the drinking container 200, forming a fine foam layer 105. Generally, the ratio of the liquid part to the foam part is considered to be good at 70:30, so the above procedure is adopted, but it goes without saying that this ratio may be appropriately changed according to the consumer's preference.

[0028] 2 and 3, when the beer can 100 is tilted to pour out the beer, and then the beer can 100 is turned upright, the small amount of beer remaining on the foamed portion 11 flows in the opposite direction, but the pocket portion 18 has the effect of catching the backflowing beer and preventing it from leaking out to the bottom side of the beer can 100. The poured beer mainly flows down near the center of the foamed portion 11 in the width direction, and the amount of remaining beer is small, so it can be caught sufficiently.

[0029] 4 is an explanatory diagram of a second embodiment of the foaming member of the present invention. In the foaming member 20 of this embodiment, the foaming member 20 is formed in a box shape, and a hole into which a beer can 100 can be inserted is provided at the bottom part, and the foaming member 20 is fixed so as to cover one end of the beer can 100 on the spout side. As a fixing mechanism for the fixing part 22, a flap-shaped part may be provided and hooked on the edge 106. The foaming part 21 is formed by dividing the top surface part of the box with a zipper part or the like, and the foaming part 21 can be made to have a predetermined angle by cutting the zipper part and raising the foaming part 21. The pouring method is the same as the above-mentioned embodiment, in which liquid beer is poured up to about 70% without attaching the foaming member 20, and then the foaming member 20 is attached and foamed beer is poured while foaming.

[0030] 5 is an explanatory diagram of a third embodiment of the foaming member of the present invention. The foaming member 30 of this embodiment is punched out of thick paper such as coated paper as shown in the left figure, with the oval-shaped part as the fixed part 32 and filter paper attached to the tongue-shaped protruding part as the foaming part 31. When attaching it to a beer can 100, the fixed part 32 is wrapped around the body of the beer can 100 so that the foaming part 31 is located at the spout 102, and the beer can 100 is held and fixed by hand. The position of the foaming member 30 can be easily adjusted.

[0031] 6 is an explanatory diagram of the fourth embodiment of the foaming member of the present invention. The foaming member 40 of this embodiment is punched out of thick paper such as coated paper as shown in the left figure, the lower band-shaped part is the fixed part 42, and the tongue-shaped protruding part is pasted with filter paper to form the foaming part 41. The left and right ends of the fixed part 42 are pasted together to form a cylindrical shape, and after pouring liquid beer in the same manner as described above, the cylindrical fixed part 42 is attached to the body of the beer can 100, and the beer is poured while foaming on the surface of the foaming part 42. Since the cylindrical fixed part 42 can be attached to the body of the beer can 100, the attachment is stable.

[0032] 7 is an explanatory diagram of the fifth embodiment of the foaming member of the present invention. The foaming member 40 of this embodiment is punched out of thick paper such as coated paper as shown in the left figure, and filter paper is attached to form the foaming part 51, and strings 52 are attached to both sides of one end of the foaming part 51 to form a fixed part. The material of the string 52 is not particularly limited, and examples include string, vinyl string, and rubber string. When attaching to a beer can 100, the string 52 is attached to the beer can 100 by hooking it onto the pull tab 107. The pouring method is the same as in the above-mentioned embodiment.

[0033] 8 is an explanatory diagram of the sixth embodiment of the foaming member of the present invention. The foaming member 60 of this embodiment is formed by punching out thick paper such as coated paper into a fan shape, rolling it up, and pasting the ends together to form a funnel shape. Filter paper is pasted on the inner surface of the funnel-shaped part to form the foaming part 61. The end of the funnel-shaped part with a larger diameter is the fixing part 62, which is attached by fitting it into the end of the beer can 100. The fixing part 62 may be provided with a flap structure for fixing. The pouring method is the same as in the above-mentioned embodiment.

[0034] FIG. 9 is a development view of the seventh embodiment of the foaming member of the present invention. The foaming member 70 of this embodiment is formed by punching out a thick paper such as filter paper into a strip with a central portion protruding 3 cm to 7 cm, and rolling it into a ring shape. If it is made of filter paper, there is no need to provide a foaming part separately. Then, the ring-shaped part is fitted into the edge 106 of the beer can so as to be attached. FIG. 10 is a side view of the state in which it is fitted into the beer can 100. Note that, during distribution, it can be folded in two with the position having the protrusion as the center to make it flat. Note that, as shown in FIG. 9, a center line 76 may be provided at the position 7 having the protrusion. By folding from the center line, the foaming part becomes V-shaped, making it easier to pour the beer in the extension direction of the center line. Also, in FIG. 9, 77 indicates a glue margin provided at one end of the foaming member 70.

[0035] As described above, with the foaming member of the present invention, when carbonated beverages such as beer poured from the spout of the storage container flow down the foaming section, the beverage flows down while coming into contact with the surface of the foaming section, and foaming is promoted by the filter paper, etc., allowing the beverage to be poured out with good foam. EXAMPLES

[0036] <Examples 1 to 21> A foaming component having the shape shown in Figure 1 was made from coated paper, and filter paper was attached to the foaming part. A can of beer was opened and liquid beer was poured into the glass until it was about 70% full, taking care to avoid creating foam as much as possible. A foaming member was attached to the end of the can on the spout side of the can, and the angle (θ) of the foaming part relative to the opening surface of the spout was tilted in increments of about 10° so that it was 5 to 200°, and the beer was poured down while foaming in the foaming part. The following evaluations were carried out for each example. · The thickness (foaminess) of the foam layer formed in the cup was measured (mm). The fineness of the foam was evaluated visually (◎: very good, ◯: good, △: acceptable, ×: unacceptable). Fine foam lasts longer than coarse foam. Ease of pouring: We evaluated whether it was easy to pour a can of beer into a glass (◎: very good, ◯: good, △: acceptable, ×: not acceptable). Overall evaluation: Evaluation was based on the above three items (◎: very good, 〇: good, △: acceptable, ×: unacceptable).

[0037] The results are shown in Table 1. Note that the distance in the table refers to the distance from the spout to the part of the foam that hits the beer.

[0038] [Table 1]

[0039] <Examples 22 to 26> A foaming member having the shape shown in Figs. 4 to 8 was made from coated paper, and filter paper was attached to the foaming portion. Other than that, the injection, measurement, and evaluation were carried out in the same manner as in Examples 1 to 21. The results are shown in Table 2.

[0040] [Table 2]

[0041] <Example 27> A foaming member 70 having the shape shown in Figs. 9 and 10 was made from filter paper. Other than that, the injection, measurement, and evaluation were carried out in the same manner as in Examples 1 to 26. The results are shown in Table 3.

[0042] [Table 3]

[0043] Therefore, it was found that if the angle between the center line of the foaming portion in the width direction and the opening surface of the spout is between 80° and 170°, the foaming and fineness are good, and further, if it is between 100° and 130°, the foam is easy to pour.
