Description

[Technical field]

[0001] The present disclosure relates to a beverage can holder for holding a beverage can. [Background technology]

[0002] Conventionally, there have been known dilution beverages that are diluted with water, carbonated water, etc., before consumption. In recent years, the types of dilution beverages have expanded to include a wide variety of beverages, ranging from lactic acid bacteria beverages and soft drinks to alcoholic beverages (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2023-95298 A Summary of the Invention [Problem to be solved by the invention]

[0004] Since diluted beverages are diluted when consumed, they are taken out of the container in small amounts for consumption. Therefore, it is rare for the diluted beverage in the container to be consumed all at once. When storing the diluted beverage remaining in the container, it is desirable to reseal the container in order to prevent deterioration of the flavor of the beverage and contamination of the beverage with foreign matter.

[0005] On the other hand, from the viewpoint of reducing the space required for storing and displaying diluted beverages, there is a demand for using beverage cans as containers for storing diluted beverages. However, the stay-on-tab type beverage cans that are widely available in general have a structure that makes it impossible to recap them by themselves. Therefore, a means for recapping beverage cans is required.

[0006] Incidentally, recorking a beverage can is a common issue when preserving any beverage remaining in a beverage can, not limited to diluted beverages. [Means for solving the problem]

[0007] Various aspects of a beverage can holder for solving the above problems will now be described. [Mode 1] A beverage can holder comprising a main body portion having an opening at the top through which a beverage can is inserted and configured to accommodate the body of the beverage can, a lid portion which is fixed to the top of the main body portion to cover the top lid of the beverage can, and a sealing member which is pressed against the top lid around a drinking spout of the top lid of the beverage can by fixing the lid portion to the main body portion, wherein the space partitioned around the drinking spout by the sealing member abutting against the top lid is a sealed space, and the beverage can holder has a deaeration portion configured to allow communication between the inside and outside of the sealed space.

[0008] According to the above configuration, the periphery of the mouth of the beverage can is sealed by the sealing member, so that the beverage can can be recapped after being opened. Even if the internal pressure around the mouth increases due to gas generated from the beverage after recapture, the gas can be released by communicating the inside and outside of the sealed space with each other by the degassing section. Therefore, when the beverage can is recapped, the generation of popping noise is suppressed, and the fixation of the lid to the body can be smoothly loosened.

[0009] [Aspect 2] The sealing member is a sealing portion configured to be elastically deformable, and includes an annular sealing portion that is pressed against the top lid of the beverage can around the drinking spout of the top lid when the lid portion is fixed to the main body, and the sealing portion includes a deaeration portion that connects the inside and outside of the sealing portion as the deformation caused by the fixation is restored when the fixation of the lid portion to the main body is loosened.A beverage can holder as described in [Aspect 1]. According to the above-mentioned configuration, when the cover is opened, the gas is released from the degassing section, so that the internal pressure gradually decreases. Therefore, the function of the degassing section can be realized with a simple configuration.

[0010] [Aspect 3] A beverage can holder as described in [Aspect 2], wherein the deaeration portion is a notch located at the lower end of the sealing portion. According to the above-mentioned configuration, the function of the deaeration section, which restores its shape when the fixation of the lid section is loosened to connect the inside and outside of the sealing section, can be accurately obtained.

[0011] [Aspect 4] A beverage can holder as described in [Aspect 2] or [Aspect 3], wherein the top lid of the beverage can has a can groove which is an annular groove along the seaming portion which is the connection portion between the can body and the top lid, the sealing portion has an annular mating piece which is fitted into the can groove by fixing the lid portion to the main body portion, and the mating piece has the deaeration portion.

[0012] In the above-mentioned configuration, the fitting piece is easily crushed when the sealing member is pressed against the beverage can. Therefore, since the fitting piece has a deaeration portion, the deaeration portion can accurately perform the function of restoring its shape when the lid is loosened, thereby connecting the inside and outside of the sealing portion.

[0013] [Aspect 5] A beverage can holder described in any one of [Aspect 1] to [Aspect 4], having structure on the upper end of the main body portion and the inner surface of the lid portion for regulating rotation for progressing screwing of the lid portion onto the main body portion.

[0014] This configuration prevents the lid from being overtightened when screwing onto the main body, and therefore prevents the need for a large force to loosen the lid from the main body even when the internal pressure in the space around the spout is high due to gas produced by the beverage.

[0015] [Aspect 6] A beverage can holder described in any one of [Aspect 1] to [Aspect 5], wherein the sealing member has a main wall portion having an upper surface facing the lid portion and is attached to the inside of the lid portion, the lid portion has a top wall portion in contact with the upper surface of the main wall portion of the sealing member, and the top wall portion has a through hole that penetrates the top wall portion.

[0016] According to the above-mentioned configuration, by inserting a rod-shaped structure into the through hole and pressing down the seal member, even if the seal member is strongly fixed to the lid, the seal member can be easily removed from the lid, and therefore the seal member can be easily washed.

[0017] [Aspect 7] A beverage can holder as described in any one of [Aspect 1] to [Aspect 6], wherein the sealing member has greater elasticity than the lid portion and comprises a main wall portion having a curved upper surface that convex toward the lid portion, an annular outer periphery surrounding the main wall portion, and an annular groove recessed downward between the upper surface of the main wall portion and the outer periphery, and the inner surface of the top of the lid portion has unevenness corresponding to the unevenness formed by the main wall portion, the outer periphery and the annular groove of the sealing member, and the sealing member is attached to the inside of the lid portion by fitting these unevennesses together.

[0018] According to the above configuration, since the seal member and the lid have upwardly convex curved surfaces, it is possible to form the seal member and the lid in a shape that suppresses deformation due to internal pressure even when the internal pressure in the space around the spout is increased by gas generated from the beverage. In addition, since the seal member is attached to the inside of the lid by fitting the convex and concave portions, the fixation of the seal member to the lid is strengthened and the displacement of the seal member from the lid is suppressed. Therefore, when the lid is fixed to the main body, the seal member accurately seals the periphery of the spout of the beverage can.

[0019] [Aspect 8] The sealing member further includes an annular sealing portion extending downward from the underside of the main wall portion inside the outer periphery, and an annular insertion groove located between the sealing portion and the outer periphery, the sealing portion having a sealing surface that contacts the top lid by fixing the lid portion to the main body, and the fixing of the lid portion to the main body causes a seaming portion, which is the connection portion between the can body and the top lid of the beverage can, to be inserted into the insertion groove. [Aspect 7] A beverage can holder as described in According to the above-mentioned configuration, the sealing function of the seal member for sealing the upper part of the beverage can is improved, so that the sealing performance around the drinking spout is improved.

[0020] [Aspect 9] A beverage can holder described in any one of [Aspect 1] to [Aspect 8], wherein the main body portion has a plurality of openings on the side and is provided with a connecting portion connecting the top and bottom of the main body portion between adjacent openings, and a rib located on the outer surface of the connecting portion and extending along the extension direction of the connecting portion.

[0021] According to the above configuration, since the main body has an opening on the side, the side of the beverage can is visible when the beverage can is held in the beverage can holder. Also, since the main body has an opening on the side, when loosening the fastening of the lid to the main body, the user can grasp the beverage can together with the main body, so that the positions of the main body and the beverage can be stabilized. Furthermore, since a rib is provided on the outer surface of the connecting part, the strength of the connecting part is increased, and the user can easily grasp the main body at the connecting part by hooking his / her fingers on the rib. Therefore, the user can easily apply force to the beverage can holder to loosen the fastening of the lid to the main body.

[0022] [Aspect 10] A beverage can holder described in any one of [Aspect 1] to [Aspect 9], wherein the main body portion has a first side opening which is an opening on a side surface, and the lid portion can be stored inside the main body portion through the first side opening.

[0023] According to the above configuration, since the main body has an opening on the side, the side of the beverage can is visible when the beverage can is held in the beverage can holder. In addition, since the main body has an opening on the side, when loosening the fixation of the lid to the main body, the user can grasp the beverage can together with the main body, so that the positions of the main body and the beverage can be stabilized. Furthermore, the lid can be stored inside the main body from the first side opening. This allows the beverage can holder to be made smaller than when the lid is attached to the top of the main body. Therefore, the space required by the beverage can holder during storage, transportation, etc. can be reduced.

[0024] [Aspect 11] A beverage can holder as described in [Aspect 10], wherein the main body portion has a second side opening on a side surface which is an opening facing the first side opening, and in the direction in which the main body portion extends, the maximum diameter at the first side opening is larger than the outer diameter of the lid portion and the maximum diameter at the second side opening is smaller than the outer diameter of the lid portion. According to the above configuration, the lid portion inserted inside the main body portion from the first side opening is prevented from coming out of the main body portion from the second side opening, thereby enabling the lid portion to be stored stably.

[0025] [Aspect 12] The deaeration section is a valve configured to connect the sealed space to the space outside the lid section by pressing the sealing member against the top lid section, a beverage can holder as described in [Aspect 1].

[0026] According to the above-mentioned configuration, even if the internal pressure around the spout increases due to gas generated from the beverage after recorking, the gas can be released by establishing communication between the inside and outside of the sealed space with the deaeration valve, thereby enabling the deaeration section to perform its function accurately. Effect of the Invention

[0027] According to the present disclosure, beverage cans can be recapped. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] (First embodiment) A first embodiment of a beverage can holder will be described with reference to Figures 1 to 7. In the following description, the up-down and left-right directions correspond to the directions when the beverage can holder is placed still on a horizontal surface.

[0030] [Beverage can holder configuration] As shown in FIG. 1, the beverage can holder 10 comprises a main body portion 20 that accommodates the body of a beverage can 100, and a lid portion 40 that is fixed to the upper portion of the main body portion 20 and thereby placed over the top lid of the beverage can 100.

[0031] The beverage can 100 to be held by the beverage can holder 10 is, for example, a stay-on-tab type beverage can having a capacity of 350 mL or 500 mL. The beverage can holder 10 is formed to a size corresponding to the size of the beverage can 100 to be held. The type of beverage contained in the beverage can 100 is not particularly limited. The beverage can holder 10 is preferably used when the beverage can 100 contains a diluted beverage. The beverage can holder 10 is preferably used when the beverage can 100 contains a beverage that is prone to releasing gas, such as a carbonated beverage or a fermented beverage.

[0032] The configuration of beverage can holder 10 will be further described with reference to Fig. 2. As shown in Fig. 2, beverage can holder 10 includes a seal member 60 in addition to the above-mentioned main body portion 20 and lid portion 40. Seal member 60 is attached to the inside of lid portion 40.

[0033] The detailed structure of each part will be described. The main body 20 has a cylindrical shape with an open top and a bottom. The cylinder constituting the main body 20 is a cylinder with a central axis along the up-down direction. The opening at the top end is the upper opening 30. Furthermore, the main body 20 has two openings, a first side opening 31 and a second side opening 32, on the side, and a single opening, a bottom opening 33, on the bottom.

[0034] A pair of connecting parts 21 are located between the first side opening 31 and the second side opening 32 in the circumferential direction of the main body 20, and the side openings 31, 32 are separated by these connecting parts 21. The connecting parts 21 extend along the extension direction of the tube constituting the main body 20. In other words, the main body 20 has a structure in which an upper part having an upper opening 30 and a bottom part having a bottom opening 33 are connected by the connecting parts 21.

[0035] The upper opening 30 is circular, and the diameter of the upper opening 30 is the same as the inner diameter of the upper part of the main body 20. That is, the entire upper surface of the main body 20 is open. The diameter of the upper opening 30 is larger than the outer diameter of the can body of the beverage can 100. The main body 20 has a threaded portion 22, consisting of a thread and a screw groove, on the outer surface of the upper part. The threaded portion 22 extends along the circumferential direction of the main body 20.

[0036] Bottom opening 33 is circular, and the diameter of bottom opening 33 is smaller than the inner diameter of the bottom of main body 20. That is, a part of the bottom surface of main body 20, including the center of the bottom surface, is opened. The diameter of bottom opening 33 is smaller than the outer diameter of the can body of beverage can 100. The inner diameter of the bottom of main body 20 may be the same as the inner diameter of the upper part of main body 20, or may be smaller than the inner diameter of the upper part. The drawings show a form in which the inner diameter of main body 20 gradually increases from the bottom to the upper part.

[0037] The pair of connecting portions 21 face each other across the central axis of the main body portion 20. The main body portion 20 has an outer rib 23 extending along the extension direction on the outer surface of the connecting portion 21. The outer rib 23 is located at the center of the connecting portion 21 in the circumferential direction of the main body portion 20.

[0038] Moreover, the main body 20 has an inner rib 24 extending along the extension direction on the inner surface of the main body 20. The inner rib 24 is located, for example, on the inner surface of the connecting portion 21 and the inner surface of the portion located above each of the side openings 31, 32 at the upper part of the main body 20. By providing the inner rib 24, the strength of the main body 20 is increased, and the beverage can 100 accommodated in the main body 20 is prevented from moving inside the main body 20 while ensuring a large diameter of the upper opening 30.

[0039] The shapes of the side openings 31 and 32 will be described in detail with reference to Fig. 3. As shown in Fig. 3, when viewed from a position facing the center of the first side opening 31, the first side opening 31 has a shape including an upper protrusion 34 protruding upward from the upper side of the rectangle and a lower protrusion 35 protruding downward from the lower side of the rectangle at the center in the left-right direction of the approximately rectangular shape. The upper protrusion 34 and the lower protrusion 35 face each other. In other words, at the center of the first side opening 31 in the circumferential direction of the main body 20, the outer edge of the first side opening 31 is recessed at the positions of the protrusions 34 and 35 so that the upper protrusion 34 protrudes upward and the lower protrusion 35 protrudes downward.

[0040] When viewed from a position facing the center of the second side opening 32, the second side opening 32 has a substantially rectangular shape similar to that of the first side opening 31 when it does not have the protrusions 34, 35. The first side opening 31 and the second side opening 32 face each other with the central axis of the main body 20 in between.

[0041] The maximum diameter D1 of the first side opening 31 in the extension direction is the diameter of the first side opening 31 at the positions of the protrusions 34, 35, and the maximum diameter D1 is greater than the maximum value of the outer diameter of the lid portion 40. On the other hand, the maximum diameter D2 of the second side opening 32 in the extension direction is smaller than the maximum value of the outer diameter of the lid portion 40.

[0042] Returning to Fig. 2, the structure of the lid part 40 will be described. The lid part 40 includes an attachment part 41 that is screwed to the upper part of the main body part 20, a top part 50 that protrudes upward from the attachment part 41, and a protruding part 45 that protrudes from the lower end of the top part 50 and connects the attachment part 41 and the top part 50.

[0043] The mounting portion 41 is cylindrical and has a central axis along the up-down direction. The mounting portion 41 has a threaded portion 42, which is composed of a screw thread and a screw groove, on its inner surface. The threaded portion 42 extends along the circumferential direction of the mounting portion 41. The mounting portion 41 has an inner diameter that corresponds to the outer diameter of the upper part of the main body portion 20.

[0044] Top portion 50 includes a disk-shaped top wall portion 51 and a peripheral wall portion 54 surrounding top wall portion 51. The outer diameter of top portion 50 is smaller than the outer diameter of mounting portion 41. When viewed from the vertical direction, top portion 50 is located inside mounting portion 41, and overhanging portion 45 is located between mounting portion 41 and top portion 50.

[0045] Top wall portion 51 has a circular shape when viewed in the up-down direction. The upper and lower surfaces of top wall portion 51 are curved surfaces corresponding to a part of a sphere, and are upwardly convex surfaces. Top wall portion 51 has through-hole 52, which is a hole penetrating top wall portion 51, near the outer edge of top wall portion 51. Top wall portion 51 also has a hemispherical protrusion 53 in the center of top wall portion 51 that protrudes downward from the lower surface of top wall portion 51.

[0046] The peripheral wall portion 54 includes an inner wall portion 55 rising from the outer edge of the top wall portion 51, an outer wall portion 56 located outside the inner wall portion 55 in the radial direction of the lid portion 40, and an upper wall portion 57 connecting the upper end of the inner wall portion 55 and the upper end of the outer wall portion 56. When viewed in the up-down direction, the upper wall portion 57 has a circular band shape.

[0047] The overhanging portion 45 connects the upper end of the mounting portion 41 and the lower end of the outer wall portion 56. When viewed in the up-down direction, the overhanging portion 45 has a circular band shape. The mounting portion 41 extends downward from the outer peripheral edge of the overhanging portion 45, and the outer wall portion 56 extends upward from the inner peripheral edge of the overhanging portion 45.

[0048] Next, a description will be given of the structure of the seal member 60. The seal member 60 is attached to the inside of the top portion 50 of the lid portion 40. The sealing member 60 has a circular shape when viewed in the up-down direction, and includes a disk-shaped main wall portion 61 and an outer circumferential portion 63 surrounding the main wall portion 61. The sealing member 60 has an outer diameter corresponding to the inner diameter of the top portion 50 of the lid portion 40.

[0049] The main wall portion 61 has a circular shape when viewed in the up-down direction. The upper and lower surfaces of the main wall portion 61 are curved surfaces corresponding to a part of a sphere, and are upwardly convex surfaces. The main wall portion 61 has a hemispherical recess 62 in the center of the main wall portion 61 that is recessed in the upper surface of the main wall portion 61.

[0050] The outer periphery 63 has an annular shape, and the seal member 60 further includes an annular groove 64 between the main wall portion 61 and the outer periphery 63, the annular groove 64 being a groove recessed downward from the outer edge of the upper surface of the main wall portion 61. When viewed in the up-down direction, the annular groove 64 has a ring-like band shape.

[0051] The structure of the back side of the sealing member 60 will be described with reference to Fig. 4. The back side of the sealing member 60 faces downward and faces the beverage can 100, and Fig. 4 is a view of the sealing member 60 as seen from the back side. In other words, the direction from the bottom to the top of the paper in Fig. 4 is the direction from the top to the bottom of the sealing member 60.

[0052] The seal member 60 has a sealing portion 70 extending downward from the edge of the lower surface of the main wall portion 61. The sealing portion 70 has an annular shape, and is located inside the outer periphery 63 in the radial direction of the seal member 60. The seal member 60 further has an insertion groove 74, which is a thin annular groove, between the sealing portion 70 and the outer periphery 63.

[0053] The sealing portion 70 has a sealing surface 71, which is a circular band-shaped surface, at its lower end, and is provided with a fitting piece 72 that protrudes downward from the outermost radial portion of the sealing surface 71. The fitting piece 72 has an annular shape and protrudes downward beyond the lower end of the outer circumferential portion 63. The fitting piece 72 has a stepped structure with respect to the sealing surface 71 on the inside of the base, i.e., at the portion connected to the sealing surface 71.

[0054] The fitting piece 72 has a notch 73 in the middle of the ring, which is a portion where the lower end of the fitting piece 72 is cut out. For example, the fitting piece 72 has two notches 73, and the two notches 73 are arranged at positions facing each other in the ring formed by the fitting piece 72. The notch 73 is an example of a deaeration portion. The number of notches 73 is not limited to two, and may be one or three or more.

[0055] The seal member 60 is configured to be elastically deformable. The seal member 60 has higher elasticity than both the main body 20 and the lid 40. The material of the seal member 60 is, for example, silicone. The material of the main body 20 and the lid 40 is, for example, ABS resin or polypropylene resin. The materials of the main body 20 and the lid 40 may be different from each other. For example, the lid 40 may be formed from a material with lower rigidity than the main body 20, such as when the main body 20 is made of ABS resin and the lid 40 is made of polypropylene resin.

[0056] [Beverage can holding structure] The structure of the beverage can holder 10 for holding the beverage can 100 will be described with reference to Fig. 5. Fig. 5 shows a cross-sectional structure of the beverage can holder 10 in a state in which the beverage can 100 is held.

[0057] First, a structure in which the seal member 60 is assembled to the lid portion 40 will be described. The seal member 60 is attached to the lid portion 40 by fitting the unevenness on the upper surface of the seal member 60 into the unevenness on the inner surface of the top portion 50 of the lid portion 40.

[0058] Specifically, on the inner surface of top 50, an upper portion of outer periphery 63 of sealing member 60 is fitted into recess 58 defined by inner wall portion 55, outer wall portion 56 and upper wall portion 57 of peripheral wall portion 54. In the vertical direction, the length of outer periphery 63 is smaller than the length of outer wall portion 56, and outer periphery 63 does not protrude downward beyond top 50.

[0059] Furthermore, on the inner surface of top 50, at the boundary between top wall 51 and peripheral wall 54, a convex portion 59 composed of the outer edge of top wall 51 and the lower end of inner wall 55 is located, and this convex portion 59 fits into annular groove 64 of seal member 60. The lower surface of top wall 51 is in contact with the upper surface of main wall 61 of seal member 60, and protrusion 53 located in the center of top wall 51 fits into recess 62 in the center of main wall 61.

[0060] In this way, the inner surface of the top 50 of the lid 40 has irregularities corresponding to the irregularities formed by the main wall 61, outer circumferential portion 63, and annular groove 64 of the sealing member 60, and the top 50 and the sealing member 60 are in close contact with each other without any gaps. The elasticity of the sealing member 60 makes it possible to suitably prevent the formation of a gap between the top 50 and the sealing member 60. When removing the sealing member 60 from the top 50 for cleaning or the like, the sealing member 60 can be easily separated from the lid 40 by pressing the sealing member 60 down with a rod-shaped structure through the through-hole 52 of the top wall 51 of the top 50.

[0061] Next, the holding structure of the beverage can 100 will be described. The beverage can 100 includes a cylindrical can body 105 and an upper lid 101 that closes the upper end of the can body 105. The beverage can 100 further includes a seaming portion 102 that is a connection portion between the upper lid 101 and the can body 105. The seaming portion 102 is a portion that is crimped when the upper lid 101 is attached to the can body 105. The seaming portion 102 has an annular shape that follows the outer edge of the upper lid 101, and protrudes upward from the upper surface of the upper lid 101. The upper surface of the upper lid 101 is the surface on which the drinking spout 104 is formed in the upper lid 101. The upper lid 101 has a can groove 103 that is an annular groove that follows the seaming portion 102 on the edge.

[0062] The beverage can 100 is inserted into the main body 20 from the upper opening 30 of the main body 20. The bottom of the beverage can 100 is supported by the bottom of the main body 20, and the top of the can body 105 of the beverage can 100 is supported by the top of the main body 20.

[0063] Since the main body 20 has the side openings 31, 32, the user can visually check the side of the beverage can 100 even if the main body 20 is colored. Therefore, the user can check the type of beverage contained in the beverage can 100 while the beverage can 100 is held in the beverage can holder 10. Furthermore, information such as the production lot and expiration date of the beverage is usually written on the bottom of the beverage can 100. Since the main body 20 has the bottom opening 33, the user can visually check the bottom of the beverage can 100 even if the main body 20 is colored. Therefore, the user can check information about the beverage while the beverage can 100 is held in the beverage can holder 10. Furthermore, since the main body 20 has the side openings 31 and 32 and the bottom opening 33, it is possible to reduce the weight of the main body 20 and the amount of material required to form the main body 20.

[0064] The lid portion 40 with the sealing member 60 attached is placed over the upper part of the main body portion 20, and the threaded portion 22 of the main body portion 20 and the threaded portion 42 of the lid portion 40 are fitted together, whereby the mounting portion 41 of the lid portion 40 is fixed to the outside of the upper part of the main body portion 20. As the threaded portions 22, 42 are fitted together, the lid portion 40 descends, and the sealing member 60 is pressed against the beverage can 100.

[0065] In detail, the sealing portion 70 of the sealing member 60 is pressed against the top lid 101 of the beverage can 100. As a result, the sealing surface 71 of the sealing portion 70 is brought into close contact with the outer edge of the top surface of the top lid 101. Furthermore, the fitting piece 72 of the sealing member 60 is fitted into the can groove 103. Then, the seaming portion 102 is inserted into the insertion groove 74 of the sealing member 60.

[0066] This brings beverage can 100 and sealing member 60 into close contact with the outer periphery of drinking spout 104 of beverage can 100. If the base of fitting piece 72 has a step, it is possible for fitting piece 72 to be in close contact with the outer edge of the upper surface of upper lid 101 within insertion groove 74, even if there is a slight difference in the diameter of the upper surface of upper lid 101 for each product type. Fitting piece 72 has notch 73 as shown in Fig. 4, but as the lower end of fitting piece 72 is pressed against can groove 103, notch 73 is crushed, and no gap is formed between beverage can 100 and sealing portion 70.

[0067] The area around the drinking spout 104 is a sealed space defined by the upper surface of the top lid 101, the lower surface of the main wall portion 61 of the sealing member 60, and the side surface of the sealing portion 70. In other words, the space inside the sealing portion 70 is a sealed space that is isolated from the space outside the sealing portion 70. This space defined around the drinking spout 104 is an example of a sealed space.

[0068] As described above, according to the beverage can holder 10 of this embodiment, the lid portion 40 is fixed to the main body portion 20, and the sealing member 60 is pressed against the beverage can 100, sealing the periphery of the drinking spout 104. This makes it possible to recap the beverage can 100 after it has been opened. This prevents the flavor of the beverage remaining in the beverage can 100 from deteriorating and prevents foreign matter from entering the beverage can 100.

[0069] According to the beverage can holder 10 of this embodiment, it is possible to improve the sealing performance around the drinking spout 104 compared to a structure in which the periphery of the drinking spout 104 is sealed only by a cap attached to the top of the beverage can 100. Therefore, even if the beverage can 100 and the beverage can holder 10 fall over, the leakage of the beverage is suppressed.

[0070] In particular, when the content of beverage can 100 is a beverage that easily produces gas, such as a carbonated beverage or a fermented beverage, the generation of gas increases the internal pressure in the space around drinking spout 104. Therefore, in a structure in which the periphery of drinking spout 104 is sealed only by the cap, the cap tends to float and the beverage is likely to leak.

[0071] On the other hand, in the beverage can holder 10 of this embodiment, the lid portion 40 is fixed to the main body portion 20, thereby defining the position of the sealing member 60 relative to the beverage can 100 and sealing the periphery of the drinking spout 104. Since the fixing of the lid portion 40 to the main body portion 20 can be made stronger than the fixing of a cap to the beverage can 100, even if the internal pressure of the space between the beverage can 100 and the sealing member 60 increases, the lid portion 40 and the sealing member 60 are prevented from floating, and thus beverage leakage can be appropriately prevented.

[0072] If the lid portion 40 is configured to be screwed to the main body portion 20, in order to loosen the fixation of the lid portion 40 to the main body portion 20, it is necessary to rotate the lid portion 40 in the circumferential direction, that is, a force in a direction different from the force that the lid portion 40 and the seal member 60 receive due to the internal pressure is required. Therefore, loosening of the fixation of the lid portion 40 due to an increase in the internal pressure is suitably suppressed.

[0073] Furthermore, since the top wall 51 of the lid portion 40 and the main wall 61 of the seal member 60 have a curvature that is upwardly convex, deformation of the main wall 61 and the top wall 51 due to an increase in internal pressure is suppressed.

[0074] Furthermore, in this embodiment, the beverage can 100 is supported in its entirety by the body 20 and the lid 40, which enhances the stability of holding the beverage can 100. Therefore, the beverage can 100 is also more likely to be prevented from falling over.

[0075] When the beverage can 100 is opened again, the lid portion 40 is rotated in the circumferential direction to loosen the fixation of the lid portion 40 to the body portion 20. At this time, as the lid portion 40 rises due to the loosening of the fixation of the lid portion 40, the pressure of the sealing member 60 against the beverage can 100 weakens, and the shape of the sealing member 60 that was elastically deformed is restored. In other words, the shape of the notch portion 73 that was crushed by the fitting piece 72 being pressed against the can groove 103 returns to its original shape.

[0076] This creates a gap between top lid 101 of beverage can 100 and sealing portion 70 of sealing member 60 at the position of cutout 73, connecting the spaces inside and outside sealing portion 70, and releasing the seal around spout 104. As a result, even if gas generated from the beverage has accumulated in the space around spout 104, the gas will gradually escape through cutout 73.

[0077] When the internal pressure in the space between the beverage can 100 and the sealing member 60 is high, attempting to loosen the fixation of the lid portion 40 to the main body portion 20 requires a large amount of force, and if the seal around the drinking spout 104 is suddenly released, a loud popping noise will be produced.

[0078] In contrast, in this embodiment, the internal pressure gradually decreases as the gas escapes through the cutout portion 73, thereby suppressing the occurrence of popping sounds and allowing the fixation of the lid portion 40 to the main body portion 20 to be smoothly loosened.

[0079] Furthermore, since the main body 20 is provided with the side openings 31, 32, when loosening the fastening of the lid 40 to the main body 20, the user can directly grasp the beverage can 100 together with the main body 20. This prevents the beverage can 100 from moving relative to the main body 20 and stabilizes the position of the beverage can 100, making it easier to perform the operation of loosening the fastening of the lid 40.

[0080] When loosening the fixation of lid portion 40, it is assumed that the user will grasp beverage can 100 together with connecting portion 21 of main body 20, and rotate lid portion 40 while pressing connecting portion 21. In this case, a large force is applied to connecting portion 21, but since connecting portion 21 is provided with outer ribs 23, the strength of connecting portion 21 is increased, and deformation of connecting portion 21 is suppressed. Furthermore, since outer ribs 23 are provided, when a user presses connecting portion 21, the user's fingers hook on outer ribs 23, preventing the hand from slipping, making it easier to press connecting portion 21.

[0081] Furthermore, if the lid portion 40 is formed from a material having a lower rigidity than the main body portion 20, it will be easier to loosen the screws of the lid portion 40 compared to when the lid portion 40 has the same high rigidity as the main body portion 20.

[0082] [Beverage can holder storage configuration] The storage form of beverage can holder 10 will be described with reference to Figures 6 and 7. For example, beverage can holder 10 is in the storage form during storage or transportation.

[0083] 6, the lid portion 40 to which the seal member 60 is attached is inserted into the inside of the main body portion 20 from the first side opening 31 of the main body portion 20. As described above, the maximum diameter of the first side opening 31 in the extension direction of the main body portion 20, i.e., the diameter of the portion where the protrusions 34, 35 are located, is larger than the maximum outer diameter of the lid portion 40, i.e., the outer diameter of the attachment portion 41. Therefore, the lid portion 40 can be inserted into the inside of the main body portion 20 from the portion of the first side opening 31 where the protrusions 34, 35 are located.

[0084] On the other hand, the maximum diameter of the second side opening 32 in the extension direction is smaller than the maximum outer diameter of the lid portion 40. Therefore, the lid portion 40 inserted into the inside of the main body portion 20 from the first side opening 31 does not come out of the main body portion 20 from the second side opening 32.

[0085] In addition, in the extension direction, the diameter of the first side opening 31 other than the portion where the protrusions 34, 35 are located matches the diameter of the opposing second side opening 32, and is smaller than the outer diameter of the mounting portion 41 but larger than the outer diameter of the top portion 50. The width of the protrusions 34, 35 is slightly larger than the vertical width of the mounting portion 41, and when the cover portion 40 is inserted into the inside of the main body portion 20 from the first side opening 31, the mounting portion 41 passes through the expanded diameter portion where the protrusions 34, 35 are located, and the top portion 50 passes through a portion of the first side opening 31 adjacent to the expanded diameter portion.

[0086] 7, by adopting a storage configuration in which lid portion 40 is placed inside main body portion 20, beverage can holder 10 can be made smaller than a state in which lid portion 40 is attached to the top of main body portion 20, such as when holding beverage can 100. Therefore, the space required by beverage can holder 10 for storage, transportation, etc. can be reduced.

[0087] Moreover, the lid part 40 can be inserted into the main body part 20 only from the first side opening 31, and the entry and exit of the lid part 40 from the second side opening 32 is restricted. This prevents the lid part 40 from going out of the main body part 20, improving the stability of the storage form.

[0088] As described above, according to the first embodiment, the following effects can be obtained. (1) When the lid portion 40 is fixed to the body portion 20, the sealing member 60 is pressed against the beverage can 100, sealing the periphery of the drinking spout 104. This allows the beverage can 100 to be recapped after it has been opened.

[0089] (2) The sealing member 60 includes an annular sealing portion 70 that is pressed against the top lid 101 around the drinking spout 104. The sealing portion 70 includes a notch 73 that connects the inside and outside of the sealing portion 70 as the elastic deformation returns to its original state when the fixation of the lid portion 40 to the main body portion 20 is loosened. As a result, even if the internal pressure of the sealed space inside the sealing portion 70 is increased due to gas generated from the beverage, the gas escapes through the notch 73 when the lid portion 40 is opened, and the internal pressure gradually decreases. This prevents popping sounds from occurring and allows the fixation of the lid portion 40 to the main body portion 20 to be loosened smoothly.

[0090] (3) If the notch 73 is located at the lower end of the sealing portion 70, the function of the notch 73, which restores its shape as the fixation of the lid portion 40 is loosened and connects the inside and outside of the sealing portion 70, can be accurately obtained.

[0091] (4) The sealing portion 70 has an annular fitting piece 72 that fits into the can groove 103, and the fitting piece 72 has a notch 73. Since the fitting piece 72 extends to the lowest part of the seal member 60 and is thin, if the fitting piece 72 has the notch 73, the notch 73 is likely to be crushed when the lid portion 40 is fixed to the main body 20. Therefore, the function of the notch 73, which restores its shape as the fixation of the lid portion 40 is loosened and connects the inside and outside of the sealing portion 70, can be accurately obtained.

[0092] (5) The seal member 60 has the main wall portion 61, the outer circumferential portion 63, and the sealing portion 70, and the periphery of the drinking spout 104 is surrounded by the seal member 60, thereby improving the sealing performance around the drinking spout 104. (6) The main wall 61 of the sealing member 60 and the top wall 51 of the lid 40 have an upwardly convex curvature. That is, the upper and lower surfaces of the main wall 61 and the upper and lower surfaces of the top wall 51 are curved surfaces that are upwardly convex. This prevents the main wall 61 and the top wall 51 from deforming even if the internal pressure of the space defined by the sealing member 60 around the drinking spout 104, i.e., the sealed space, increases.

[0093] (7) The inner surface of the top 50 of the lid 40 has projections and recesses corresponding to the projections and recesses formed by the main wall 61, outer circumferential portion 63, and annular groove 64 of the sealing member 60, and these projections and recesses fit together to attach the sealing member 60 to the inside of the lid 40. With this configuration, the fixing of the sealing member 60 to the lid 40 is strengthened and displacement of the sealing member 60 from the lid 40 is suppressed, thereby favorably achieving the effect of (1) above.

[0094] (8) The top wall 51 of the lid 40 has a through hole 52. Therefore, by inserting a rod-shaped structure into the through hole 52 and pressing down on the sealing member 60, the sealing member 60 can be easily removed from the lid 40 even if the sealing member 60 is strongly fixed to the lid 40. This makes it easy to wash the sealing member 60, which is prone to having beverages stick to it. Therefore, the growth of mold and the like is suppressed, making it easy to keep the sealing member 60 clean.

[0095] (9) The seal member 60 has an insertion groove 74 on the outside of the sealing portion 70, and when the lid portion 40 is fixed to the body portion 20, the seaming portion 102 of the beverage can 100 is inserted into the insertion groove 74. This improves the sealing function of the seal member 60 with respect to the upper portion of the beverage can 100, thereby improving the airtightness around the drinking spout 104.

[0096] (10) In main body 20, outer ribs 23 are provided on the outer surface of connecting portion 21, extending in the direction in which connecting portion 21 extends. This increases the strength of connecting portion 21 and makes it easier for a user to grasp main body 20 at connecting portion 21 by hooking his / her fingers on outer ribs 23. This makes it easier for a user to apply force to beverage can holder 10 to loosen the fixation of lid 40 to main body 20.

[0097] (11) Lid 40 can be stored inside main body 20 from first side opening 31 of main body 20. This allows beverage can holder 10 to be made smaller than when lid 40 is attached to the top of main body 20. This allows the space required by beverage can holder 10 for storage, transportation, etc. to be reduced.

[0098] (12) In the extension direction of the main body 20, the maximum diameter at the first side opening 31 is larger than the outer diameter of the lid portion 40, and the maximum diameter at the second side opening 32 is smaller than the outer diameter of the lid portion 40. This prevents the lid portion 40, which is inserted into the inside of the main body 20 from the first side opening 31, from going out of the main body 20 from the second side opening 32, so that the lid portion 40 can be stored stably.

[0099] Second embodiment A second embodiment of a beverage can holder will be described with reference to Figures 8 and 9. The following description will focus on the differences between the second embodiment and the first embodiment, and the same components as those in the first embodiment will be given the same reference numerals and will not be described.

[0100] As shown in Fig. 8, the beverage can holder 11 of the second embodiment has a deaeration valve 80 for reducing the internal pressure in the space between the beverage can 100 and the sealing member 60 when the beverage can 100 held by the beverage can holder 11 is opened. The deaeration valve 80 is an example of a deaeration section. The deaeration valve 80 is attached to the center of the top wall portion 51 at the top 50 of the lid portion 40. In the beverage can holder 11 of the second embodiment, the sealing member 60 does not have a notch portion 73.

[0101] As shown in Fig. 9, the deaeration valve 80 includes a valve body 81 and an operation part 82 that is operated by a user. The valve body 81 passes through the top wall 51 and is attached to the main wall 61 of the seal member 60. The valve body 81 has a columnar upper part with a larger diameter at the bottom, which protrudes outward. The operation part 82 is connected to the upper part of the valve body 81 and protrudes to the outside of the top wall 51.

[0102] 9 shows the deaeration valve 80 in a closed state, in which the main wall portion 61 surrounds the valve body portion 81 and is in close contact with the valve body portion 81. Therefore, the space around the drinking spout 104, i.e., the space inside the sealing portion 70 of the sealing member 60, is sealed. The lower surface of the valve body portion 81 faces this sealed space.

[0103] When opening a beverage can, a user first presses the operating portion 82 from outside the beverage can holder 11 to press down the valve body portion 81. If the underside of the valve body portion 81 is inclined so that the outer edge is located above the center of the underside, the internal pressure is prevented from acting on the underside of the valve body portion 81 in a direction opposite to the downward pushing of the valve body portion 81, compared to when the underside is a flat surface aligned in the horizontal direction. Therefore, the force required to push down the valve body portion 81 is prevented from becoming large.

[0104] By pushing down the valve body 81, a gap is created between the main wall 61 of the seal member 60 and the valve body 81, and the space inside the sealing portion 70 is connected to the space outside the lid portion 40. As a result, the seal around the drinking spout 104 is released, and even if gas generated from the beverage has accumulated in the space inside the sealing portion 70, the gas escapes to the space outside the lid portion 40.

[0105] Then, after such operation of the degassing valve 80, the fixation of the lid portion 40 to the main body portion 20 is loosened. This makes it possible to suppress the occurrence of popping sounds and to smoothly loosen the fixation of the lid portion 40 to the main body portion 20.

[0106] In the second embodiment, the deaeration valve 80 can be disassembled by separating the valve body portion 81 and the operation portion 82, thereby removing the deaeration valve 80 from the lid portion 40 and the sealing member 60. Then, the sealing member 60 can be removed from the lid portion 40 by utilizing the hole in the top wall portion 51 through which the deaeration valve 80 was passed. Therefore, in the beverage can holder 11 of the second embodiment, the top wall portion 51 of the lid portion 40 does not need to have the through-hole 52.

[0107] Furthermore, the position of the deaeration valve 80 is not particularly limited as long as the deaeration valve 80 penetrates the lid portion 40 and is assembled to the seal member 60, and the lower surface of the valve body portion 81 is in a position facing the space inside the sealing portion 70. If the deaeration valve 80 is attached to the center of the top wall portion 51 and the main wall portion 61, it is easy for the user to apply force to the operating portion 82 to press down the valve body portion 81.

[0108] As described above, according to the second embodiment, in addition to the advantages (1), (5) to (7), and (9) to (12) of the first embodiment, the following advantages can be obtained. (13) Beverage can holder 11 is provided with vent valve 80 configured to allow communication between the space partitioned around spout 104, i.e., the sealed space, and the space outside lid portion 40. With this configuration, vent valve 80 allows communication between the above spaces, thereby allowing gas accumulated around spout 104 to escape. This reduces the generation of popping sounds when loosening lid portion 40 from main body 20, and also prevents the force required to loosen lid portion 40 from increasing. (14) The vent valve 80 penetrates the top 50 of the lid 40 and is attached to the seal member 60. With this configuration, the vent valve 80 is easy to operate and install.

[0109] Third embodiment A beverage can holder according to a third embodiment will be described with reference to Figures 10 to 13. The following description will focus on the differences between the third embodiment and the first embodiment, and the same components as those in the first embodiment will be given the same reference numerals and will not be described.

[0110] The beverage can holder 12 of the third embodiment has a structure that restricts rotation for the progress of screwing of the lid portion 40 to the main body portion 20. Specifically, as shown in Fig. 10, the main body portion 20 is provided with a main body rotation restricting portion 25 at the upper end of the main body portion 20. The main body rotation restricting portion 25 includes, for example, a stepped structure, and two main body rotation restricting portions 25 are provided at positions facing each other in a circular ring at the upper end of the main body portion 20. In the embodiment shown in Fig. 10, a step is formed at the position of the main body rotation restricting portion 25, where the height of the upper end of the main body portion 20 changes sharply, and the upper end that is elevated by the step gradually becomes lower toward the opposing main body rotation restricting portion 25.

[0111] 11, the lid 40 is provided with a lid rotation restricting portion 46 on the underside of the protruding portion 45. The lid rotation restricting portion 46 includes, for example, a ridge-like structure capable of engaging an end face of a step in the main body rotation restricting portion 25, and two lid rotation restricting portions 46 are provided at positions facing each other on the annular ring on the underside of the protruding portion 45. In the embodiment shown in FIG. 11, the lid rotation restricting portion 46 has a ridge-like shape that fits onto the upper end of the main body 20 in response to changes in the height of the upper end.

[0112] In the third embodiment, when the lid part 40 is rotated in the circumferential direction to be screwed to the main body part 20, as the screwing progresses, the lid part 40 descends and the lower surface of the protruding part 45 approaches the vicinity of the upper end of the main body part 20, and the rotation of the lid part 40 is restricted by the engagement between the main body rotation restricting part 25 and the lid rotation restricting part 46. For example, the end face of the protrusion of the lid rotation restricting part 46 abuts on the end face of the step of the main body rotation restricting part 25, making it impossible to further rotate the lid part 40. The rotation restricting parts 25, 46 are arranged so that the rotation restricting parts 25, 46 engage at a position where the screwing of the lid part 40 has progressed to such an extent that the periphery of the mouth of the beverage can is adequately sealed by the sealing member 60, in other words, at a position where the lid part 40 has descended to a position where the sealing member 60 is appropriately pressed against the upper lid of the beverage can.

[0113] This prevents the lid 40 from being overtightened relative to the body 20 when screwing the lid 40 to the body 20. Therefore, when opening the bottle, even if the internal pressure in the space around the spout is high due to gas generated from the beverage, the need for a large force to loosen the lid 40 relative to the body 20 is reduced.

[0114] Note that main body rotation restricting portion 25 and lid rotation restricting portion 46 may have a structure that restricts the rotation of lid portion 40 by engaging with each other, and the structure of rotation restricting portions 25, 46 may be different from the step or protrusion described above. For example, in a modified beverage can holder 13 shown in Figures 12 and 13, main body rotation restricting portion 25 includes a protrusion-like structure, and lid rotation restricting portion 46 includes a protrusion-like structure that defines a groove in which the protrusion of main body rotation restricting portion 25 can be engaged. Then, the protrusion of main body rotation restricting portion 25 gets caught in the groove of lid rotation restricting portion 46, thereby restricting the rotation of lid portion 40.

[0115] Moreover, the configuration of the cover portion 40 and the seal member 60 other than the rotation restriction portions 25, 46 may be the same as that of the first embodiment, or may be the same as that of the second embodiment.

[0116] As described above, according to the third embodiment, in addition to the effects of the first and second embodiments, the following effects can be obtained. (15) Beverage can holder 12 has a structure on the upper end of main body 20 and the inner surface of lid 40 that restricts rotation for progressing screwing of lid 40 to main body 20. This prevents lid 40 from being overtightened relative to main body 20 when screwing lid 40 to main body 20. This prevents a large force from being required to loosen the fixation of lid 40 to main body 20.

[0117] [Variations] The above-described embodiments may be modified as follows. The following modifications may be combined with each other.

[0118] If the beverage can holder includes at least the main body 20 and the lid 40, it is possible to reseal an opened beverage can by placing the lid 40 over the top of the beverage can and fixing the lid 40 to the top of the main body 20. For example, if the beverage contained in the beverage can is a beverage other than a carbonated beverage or a sparkling beverage and does not require high sealing performance around the drinking spout, the beverage can holder may not include the seal member 60, or the vicinity of the drinking spout may be sealed by a seal member or a lid having a structure different from that of each of the above embodiments. Furthermore, the main body 20 may have a structure different from that of each of the above embodiments as long as it can accommodate a beverage can. [Explanation of symbols]
