Description

Technical Field

[0001] The present invention relates to a portable bottle in which a lid member is attached to a bottle body and drinking water is directly taken from a discharge path provided integrally with the lid member.

Background Art

[0002] Conventionally, as a technology related to such a portable bottle, for example, there is one shown in the following Patent Document 1 (see paragraphs

[0005] and

[0015] of the specification, FIGS. 1, 2, 4, etc.).

[0003] The technology according to Patent Document 1 relates to a bottle cap 100 having an openable and closable lid body used for a one-handed operation bottle.

[0004] The bottle cap 100 includes a lower lid body 1 attached to a bottle body 200, and an upper flip cap 2 provided on the lower lid body 1 and having one end hinged to the lower lid body 1. A water discharge passage 11 extending from the upper surface to the bottom surface is formed in the lower lid body 1. Further, the edge of the upper surface extends upward to form a lip-shaped portion 13, and the inner wall of the lip-shaped portion 13 is connected to the inner wall of the water discharge passage 11.

[0005] An upper cap buckle 31 is formed on the upper flip cap 2 and engages with a lower cap buckle 32 formed on the lip-shaped portion 13, so that the upper flip cap 2 is fixed in a closed state with respect to the lower lid body 1. When the upper cap buckle 31 and the lower cap buckle 32 are engaged, a water discharge seal protrusion 231 provided on the upper flip cap 2 seals the water discharge passage 11.

[0006] According to the one-handed operation bottle, since one end of the upper flip cap 2 is hinged to the lower lid body 1 and the other end is connected to the lower lid body 1 by a buckle, the user can open the upper flip cap 2 with one hand and the operation is convenient. Further, since the shape of the lip-shaped portion 13 coincides with the shape of the lower lip, it is said that a bottle excellent in the ease of drinking a drink can be obtained.

Summary of the Invention

Problems to be Solved by the Invention

[0008] In the portable bottle of the above Patent Document 1, although the water outlet passage 11 is disposed close to the edge of the lower lid 1, there is a predetermined distance between the water outlet passage 11 and the edge of the lower lid 1. Therefore, the edge of the lower lid 1 exists further outside the lip-shaped portion 13. In that case, whether this portable bottle is easy to drink depends on the rising height of the lip-shaped portion 13. That is, when drinking water, the user's lower lip touches the lip-shaped portion 13 and the surface of the lower lid 1 outside it, but as far as each figure is concerned, the height of the lip-shaped portion 13 is insufficient. Therefore, depending on the contact state of the lower lip, the drink is likely to spill.

[0009] Also, the formation position of the water outlet passage 11 in the lower lid 1 is not the complete end position of the lower lid 1. For this reason, on the inner surface of the lower lid 1, a ceiling surface remains outside the water outlet passage 11, and the drink inside cannot be drained unless the bottle body 200 is tilted completely upside down. Such a posture of tilting the bottle body 200 greatly may give a sense of discomfort to the people around depending on the place of use.

[0010] As described above, in the conventional portable bottle, there are still points to be improved in the function related to ease of drinking. An object of the present invention is to provide a portable bottle that has no sense of discomfort in the drinking posture and is easy to drain the drink.

Means for Solving the Problems

[0011] (Characteristic Configuration) The characteristic configuration of the portable bottle according to the present invention is a lid member integrally formed with a discharge passage, a bottle body to which the lid member is attached, An inner opening that opens to the inner surface of the lid member and an outer opening that opens to the outer surface of the lid member are formed in the discharge path. In a plan view of the lid member, the inner opening is offset outward from the central position of the lid member, and the outer opening is further offset outward with respect to the inner opening.

[0012] (Effect) By forming the inner opening of the discharge path integrally formed with the lid member at a position other than the center of the lid member and arranging the outer opening further outward than the inner opening as in this configuration, the discharge path is offset toward the outer edge side of the lid member. In particular, the outer opening can be brought closer to the outer edge. When the inner opening and the outer opening are closer to the outer edge of the lid member, it becomes easier for the water inside etc. to be discharged from the discharge path. In particular, when all the water is drained, the inclination angle of the portable bottle can be reduced compared to the case where the discharge path is formed at the center of the lid member.

[0013] Also, when the user drinks water or the like held in the portable bottle, the outer opening serves as the direct drinking port. In that case, since the outer opening is on the outside, the drinking posture approximates the posture using a normal cup, and there is no sense of discomfort in various surrounding environments.

[0014] Furthermore, although it also depends on the opening area etc. of the outer opening, even if the discharge resistance from the outer opening is large, when the portable bottle is tilted, the amount of water etc. stored upward from the outer opening increases, and a discharge effect utilizing gravity can be expected.

[0015] In the portable bottle according to the present invention, it is advantageous that the lid member is provided with a female screw portion that screws onto the top of the bottle body, the inner opening is formed at a position adjacent to the female screw portion in a plan view of the lid member, and the outer opening is formed further outward than the female screw portion.

[0016] (Effect) With the present configuration, by providing the inner opening at a position adjacent to the female screw portion of the lid member, when the portable bottle is in the drinking position, the inner opening becomes the lowest position on the ceiling surface of the lid member. Therefore, the drainage effect is maximized.

[0017] Further, since the outer opening is located further outside, the outer opening is formed at a position extremely close to the outer edge of the lid member. Therefore, the user's drinking posture becomes closer to the state of drinking water using a cup, and a more comfortable drinking posture without a sense of discomfort can be obtained.

[0018] In the portable bottle according to the present invention, the lid member is provided with a plug member for sealing and opening the discharge path, and an opening / closing body pivotally supported by the lid member in a state where the plug member is attached and changing between an open posture and a sealed posture with respect to the lid member. The shaft body and the bearing hole related to the pivotal support are separately formed with respect to the opening / closing body and the lid member, and a slide portion is provided in the bearing hole so that the opening / closing body can move along the plane direction of the lid member when the opening / closing body opens and closes.

[0019] (Effect) With the present configuration, if the opening / closing body can slide along the plane direction of the lid body when the opening / closing body opens and closes, when the opening / closing body opens and closes, it becomes easy to insert and extract the plug member along the inclined axial direction of the discharge path. The plug member is inserted and extracted while being elastically deformed with respect to the discharge path, but at that time, the possibility of excessive local deformation being applied to a specific part of the plug member is reduced. Therefore, the durability of the plug member is enhanced and a good sealing effect can be maintained over a long period. Further, since the plug member moves along the extending direction of the discharge path when the plug member is inserted and extracted, there is no sense of discomfort that an unreasonable deformation is forced on the plug member during the opening / closing operation of the opening / closing body.

[0020] In the portable bottle according to the present invention, it is advantageous that the plug member has a substantially cylindrical shape, the axial direction of the cylindrical shape of the plug member is inclined along the inclined direction of the discharge path, and a chamfered portion is formed in the tip region facing the outer opening.

[0021] (Effect) If the plug member has a cylindrical shape as in this configuration, the contact area of the plug member with respect to the discharge path increases, and the sealing effect can be further enhanced.

[0022] In addition, by forming a chamfered portion in the tip region, even if the opening / closing body slides and the axis of the plug member and the discharge path do not coincide when the opening / closing body is opened and closed, the plug member can be guided to an appropriate position. Therefore, even when the opening / closing body is allowed to slide, the sealing effect of the plug member can be surely exhibited.

[0023] In the portable bottle according to the present invention, the slide length in the direction along the slide direction of the shaft body and the clearance between the shaft body and the bearing hole can be set to 0.8 mm or less, and the clearance in the direction orthogonal to the slide direction can be set to 0.5 mm or less.

[0024] (Effect) With this configuration, regarding the clearance between the shaft body and the bearing hole, by setting the slide length in the slide direction to 0.8 mm or less and making it larger than the clearance in the direction orthogonal thereto, the opening / closing operation of the opening / closing body becomes reliable. That is, when inserting the plug member into the discharge path, the tip of the plug member can be aligned with the central position of the outer opening, and when the plug member is inserted, the position of the opening / closing body is changed according to the inclination of the discharge path. As a result, the opening / closing operation can be performed without causing unreasonable deformation to the plug member.

[0025] When the slide length is 0.8 mm, it means that the displacement between the upper end and the lower end of the plug member is allowed up to 0.8 mm in the mounting posture of the plug member. However, if the vertical length of the plug member is about 5 mm at most, and a displacement of 0.8 mm is possible within this range, when the discharge path is 20 mm or the like, the displacement between the outer opening and the inner opening becomes 3.2 mm. Since there is also the thickness of the resin or the like constituting the lid member further outside the outer opening, it is sufficiently possible to form the wall thickness of the female screw portion of the lid member to the required thickness.

[0026] On the other hand, if the gap in the direction orthogonal to the sliding direction is 0.5 mm or less, when the opening / closing body is opened and closed, the opening / closing body does not have an excessive rattling feeling from the lid member, and a good operating feeling can be maintained.

Mode for Carrying Out the Invention

[0028] (First Embodiment) (Overview) In the portable bottle B according to the present invention, a lid member 2 is attached to the bottle body 1, and the lid member 2 is further provided with an opening / closing body 3 that swings open and closed. When drinking water, the opening / closing body 3 can be opened to directly drink the drink such as water inside from the discharge path 4 formed in the lid member 2, and when not drinking water, the drink inside can be hermetically held by the opening / closing body 3. Hereinafter, an embodiment of the portable bottle B will be described with reference to FIGS. 1 to 5.

[0029] (Bottle Body) As shown in FIGS. 1 and 4, the portable bottle B includes a bottomed cylindrical bottle body 1 and a lid member 2 that is screwed onto the bottle body 1. A male screw portion 1a is formed on the bottle body 1, and a female screw portion 2a is formed on the lid member 2, and the two are screwed together. A sealing packing P that is sandwiched between the lid member 2 is provided on the outer peripheral surface of the tip of the bottle body 1. The bottle body 1 may be a simple cylindrical shape as shown in FIG. 1, or may take various shapes such as a substantially conical shape that expands in diameter toward the upper end, a spindle shape or a spool shape in which the diameter size is different as it is displaced vertically.

[0030] (Lid member) As shown in FIGS. 2 to 4, a discharge path 4 that communicates with the inside of the bottle body 1 is formed in the lid member 2. The discharge path 4 includes an inner opening 4a that opens on the back surface of the lid member 2 and an outer opening 4b that is formed in the convex portion 21 of the lid member 2. The outer opening 4b opens in the convex portion 21 formed in the lid member 2, and the user can directly touch the convex portion 21 with the mouth when drinking water and suck out the water inside.

[0031] As shown in FIG. 4, in the discharge path 4, the outer opening 4b is displaced outward from the central position of the lid member 2, and the outer opening 4b is further displaced outward with respect to the inner opening 4a.

[0032] With this configuration, the discharge path 4 can be offset to the outer edge side of the lid member 2, and in particular, the outer opening 4b can be brought closer to the outer edge. By bringing the inner opening 4a and the outer opening 4b closer to the outer edge of the lid member 2, when the portable bottle B is tilted, most of the water inside is located higher than the inner opening 4a, and the water inside is easily discharged from the discharge path 4. In particular, when all the water is drained, the tilting angle of the portable bottle B can be reduced compared to the case where the discharge path 4 is formed in the center of the lid member 2. This depends on the opening area of the outer opening 4b and the like, but when the discharge resistance is large, a discharge effect using gravity can be expected, which is advantageous.

[0033] In addition, in the portable bottle B of the present embodiment, the outer opening 4b serves as a direct drinking port. In this case, since the outer opening 4b is located on the outer peripheral portion, the drinking posture approximates the posture when using a normal cup, and it does not give a sense of discomfort to the people around in various environments.

[0034] Particularly in this configuration, the inner opening 4a is formed at a position adjacent to the female screw portion 2a, and the outer opening 4b is formed outside the female screw portion 2a. By providing the inner opening 4a in this state, when the portable bottle B is in the drinking posture, the inner opening 4a becomes the lowest position on the ceiling surface of the lid member 2, and the drainage effect becomes the highest.

[0035] In addition, since the outer opening 4b is further displaced radially outward, the outer opening 4b is formed at a position extremely close to the outer edge of the lid member 2. Therefore, the user can take a drinking posture similar to drinking water from a cup, and the sense of discomfort is further reduced.

[0036] (Water purification cartridge) As shown in FIG. 4, a water purification cartridge C is mounted inside the bottle body 1 and on the back surface of the lid member 2. The water purification cartridge C is substantially disk-shaped and covers the entire back surface of the lid member 2. Note that, as the shape of the water purification cartridge C, any shape such as a cylindrical shape other than a disk shape can be adopted.

[0037] The water purification cartridge C has some flow resistance. Therefore, the user needs to suck water with a force exceeding this flow resistance. However, since the inner opening 4a is located at the lowermost part of the back surface of the lid member 2, the suction force can be reduced by utilizing the weight of the water inside.

[0038] (Opening / closing body and plug member) As shown in FIGS. 2 to 5, an opening / closing body 3 that can be opened and closed between an open posture and a sealed posture is attached to the lid member 2 via a shaft support portion 6. A plug member 8 that abuts against the outer opening 4b and seals / opens the discharge path 4 is attached to the opening / closing body 3.

[0039] The shaft support portion 6 of the opening / closing body 3 includes a shaft body 6a integrally formed with the opening / closing body 3 and a bearing hole 6b formed in the lid member 2. As shown in FIG. 5(b), the bearing hole 6b is formed in an oval shape extending in the plane direction of the opening / closing body 3 when viewed in the extending direction of the shaft body 6a. Thereby, the shaft body 6a can move by a slide length D provided in the horizontal direction inside the bearing hole 6b. On the other hand, the difference between the diameter φ of the shaft body 6a and the height H of the bearing hole 6b is small. Note that the shaft body 6a may be configured by attaching a shaft member formed of a separate member to the opening / closing body 3.

[0040] If the opening / closing body 3 can slide along the plane direction of the lid member 2 when opening and closing as described above, when inserting and removing the plug member 8 with respect to the outer opening 4b as shown by the arrow in FIG. 5(a), the plug member 8 can move along the extending direction of the discharge path 4. The plug member 8 is inserted while being elastically deformed with respect to the discharge path 4, or is removed. With this configuration, it is difficult for the plug member 8 to be bent and excessively deformed at a specific part. Therefore, the durability of the plug member 8 is enhanced, and a good sealing effect can be maintained over a long period. In addition, an operating feeling of the opening / closing body 3 without a sense of discomfort can be obtained when inserting and removing the plug member 8.

[0041] (Dimensions of the shaft support portion) An example of the specific dimensions of the shaft support portion 6 is shown while referring to FIG. 5(b). The length in the longitudinal direction of the bearing hole 6b is formed large so that the shaft body 6a can move in the slide direction. In the present embodiment, the gap for securing this slide length D is set to 0.8 mm or less, and the gap in the direction orthogonal to the slide direction (the difference between the height H of the bearing hole 6b and the diameter φ of the shaft body 6a) is set to 0.5 mm or less.

[0042] By forming the slide portion having the slide length D of 0.8 mm or less in this way, it becomes easy to position the plug member 8 with respect to the outer opening 4b particularly when closing the opening / closing body 3. Also, as shown by the arrow in FIG. 5(a), when inserting the plug member 8 into the discharge path 4, the plug member 8 and the opening / closing body 3 can slide along the plane direction of the lid member 2, and the insertion operation of the plug member 8 becomes reliable.

[0043] When the slide length D is hypothetically 0.8 mm, the inclination angle set for the discharge path 4 is also appropriate so that the plug member 8 can be inserted without difficulty. For example, if the vertical length of the plug member 8 is at most about 5 mm, the opening / closing body 3 slides 0.8 mm while the plug member 8 is inserted 5 mm. That is, if the discharge path 4 is formed at an inclination angle of 50 to 8, the insertion operation of the plug member 8 is ensured. When the discharge path 4 is 20 mm or the like, the displacement between the outer opening 4b and the inner opening 4a is 3.2 mm. There is a thickness of the resin that forms the convex portion 21 of the lid member 2 in the outer opening 4b. When securing a displacement of 3.2 mm while considering this thickness, the inner opening 4a is formed just inside the female screw portion 2a of the lid member 2.

[0044] In addition, even when the slide length D is less than 0.8 mm, the inclination of the discharge path 4 can be ensured as it is. Since the plug member 8 can be inserted into the discharge path 4 by utilizing its own elasticity, the sealing effect of the outer opening 4b is sufficient even when the slide length D is small.

[0045] On the other hand, if the gap of the shaft support portion 6 orthogonal to the slide direction of the opening / closing body 3 is 0.5 mm or less, when the opening / closing body 3 is opened and closed, the opening / closing body 3 does not have an excessive rattling feeling with respect to the lid member 2, and a good operating feeling can be maintained. In the present embodiment, the gap is set to 0.2 mm, the diameter φ of the shaft body 6a is set to 2.5 mm, and the height H orthogonal to the slide direction of the bearing hole 6b is set to 2.7 mm.

[0046] (Shape of the plug member) As shown in FIGS. 3 to 5, the plug member 8 has an oval cross-sectional shape and extends along the inclination direction of the discharge path 4. Further, a chamfered portion 8a facing the outer opening 4b is formed at the edge of the tip of the plug member 8. In addition, the cross-sectional shape may be elliptical.

[0047] On the outer periphery of the plug member 8 at a position close to the base end side from the chamfered portion 8a, an annular convex portion 8b is provided. On the other hand, an annular concave groove 4c is formed at a position directly below the outer opening 4b in the discharge path 4. Thus, when the convex portion 8b engages with the concave groove 4c, the contact area between the two is enlarged, the sealing state of the plug member 8 becomes more stable, and the sealing effect is enhanced.

[0048] If the cross-sectional shape of the plug member 8 is oval as in this configuration, when a predetermined flow path area is ensured, when attaching the mouth to the outer opening 4b, the width of opening the mouth vertically becomes smaller, making it easier to drink water. By forming a part of the contour of the cross-sectional shape of the plug member 8 into a round shape, the sealing performance with the discharge path 4 is improved.

[0049] Also, by tilting the plug member 8 as in this configuration, the contact area of the plug member 8 with respect to the inner surface of the discharge path 4 can be increased, and the sealing effect can be further enhanced. Further, due to the chamfered portion 8a at the tip, when the opening / closing body 3 slides during opening and closing, the plug member 8 can be guided to an appropriate position even when the relative position between the plug member 8 and the discharge path 4 is different. Therefore, the sealing effect of the plug member 8 is surely exhibited.

[0050] (Engaging portion of the opening / closing body) As shown in FIGS. 1 and 2, the opening / closing body 3 is stabilized in its posture by engaging with the lid member 2 in the closed posture and the open posture. In the closed posture of FIG. 1, an engaging projection 31a inside the bent portion 31 provided at the tip of the opening / closing body 3 engages with an engaging convex portion 21a formed on the surface of the lid member 2. On the other hand, when the opening / closing body 3 is in the open posture as shown in FIGS. 2(a) and 2(b), the left and right edges 32 of the opening / closing body 3 engage in a state of being sandwiched between the opposing inner walls 22a of the recess 22 formed in the lid member 2 so as to house the opening / closing body 3.

[0051] (Air intake hole) As shown in FIG. 4, an air intake portion 9 is provided at a position directly below the male screw portion 1a in the wall portion of the bottle body 1 and at a position radially opposite to the discharge path 4. The air intake portion 9 sucks external air into the bottle body 1 in exchange for the discharge of internal water or the like during drinking. Thereby, the suction force during drinking can be reduced.

[0052] The intake part 9 is composed of an umbrella-shaped valve body 9a fixed to the wall part of the bottle body 1 and an intake hole 9b of any shape formed through at a position on the same wall part that overlaps the valve body 9a. The valve body 9a is made of an elastic material such as various rubbers similar to the plug member 8 of the discharge path 4. The position of the intake hole 9b is a part that is immersed in water or the like when the bottle body 1 is filled with the maximum amount of water or the like. However, since the valve body 9a is pressed against the inner surface of the wall part by water pressure, leakage of water or the like does not occur.

[0053] On the other hand, when the bottle body 1 is tilted during drinking, since the intake hole 9b is located above the inclined water surface, water naturally does not leak. Also, when the internal pressure of the bottle body 1 decreases as water is drunk, the valve body 9a opens and outside air is easily sucked into the bottle body 1. Therefore, a strong sucking force is not required when drinking. Furthermore, since the intake hole 9b is located above the water surface in many usage states, it becomes difficult for water to exist at the boundary between the valve body 9a and the intake hole 9b. Therefore, the amount of water vibrating with the outside air during intake is reduced, and the generation of abnormal sounds is suppressed.

[0054] (Dimensions of other parts) When the shape of the outer opening 4b is oval or elliptical, the inner diameter dimension of the long side is preferably 5 to 15 mm. If it is less than 5 mm, a sucking force is required when drinking. Therefore, it is 6 mm or more, and particularly 8 mm or more when it is desired to increase the flow rate. On the other hand, if it exceeds 15 mm, it becomes difficult to maintain airtightness when drinking. Therefore, it is appropriate to be 14 mm or less, and particularly 12 mm or less to avoid the appearance of holding something with the mouth posture. In this embodiment, it is 10 mm.

[0055] The inner diameter dimension of the short side of the outer opening 4b is preferably 2 to 10 mm. If it is less than 2 mm, a force is required when drinking. Therefore, it is 3 mm or more, and particularly 4 mm or more is preferable when increasing the flow rate. On the other hand, if it exceeds 10 mm, it is necessary to open the mouth wide, and it may seem as if holding something. Therefore, it is 9 mm or less, and particularly preferably 7 mm or less. In this embodiment, it is 5 mm.

[0056] (Material) As materials for the bottle body 1 and the lid member 2, for example, they can be made of ABS resin (Acrylonitrile-Styrene-Acrylate resin). If it is ABS resin, it has the necessary strength and is excellent in forming protruding parts such as the shaft body 6a. Also, there are few molding defects such as sink marks during resin molding, and the cost is reasonable. However, it is not limited to this. For example, for members such as the lid member 2 and the opening / closing body 3 where sliding wear and locking effects are required during opening and closing, PC (polycarbonate), PP, POM, etc. can also be used. The bottle body 1 can use stainless steel (SUS) etc. in addition to resin materials.

[0057] For members such as the plug member 8 where a sealing effect is required, for example, NBR (nitrile rubber) is used. If it is NBR, it is excellent in heat resistance and oil resistance, and the cost is also low.

[0058] (Another Embodiment) In order to minimize rattling of the opening / closing body 3 during opening and closing, the contact portion 34 and the riding portion 24 as shown in FIGS. 6(a) to 6(c) may be distributed and formed on the opening / closing body 3 and the lid member 2. For example, a part of the edge between the left and right shaft bodies 6a of the opening / closing body 3 is used as the contact portion 34, and the riding portion 24 formed on the surface of the lid member 2 is configured such that the contact portion 34 can cross over when the opening / closing body 3 rotates approximately 90 degrees. When riding up, the shaft body 6a is configured to move to one end of the bearing hole 6b so that an appropriate contact force is generated between the contact portion 34 and the riding portion 24.

[0059] With this configuration, during the opening and closing process where the opening / closing body 3 is likely to rattle due to the sliding length D between the shaft body 6a and the bearing hole 6b, the play between the shaft body 6a and the bearing hole 6b can be eliminated. Therefore, the user will not have the impression that the mounting state of the opening / closing body 3 is insufficient, and the texture of the portable bottle B is improved. Also, since the user feels an operation resistance when the opening / closing body 3 is exactly in the middle of the opening / closing area, an accent is created in the opening / closing operation and the operation feeling becomes good.

Industrial Applicability

[0060] The portable bottle according to the present invention can be widely used for all kinds of containers provided with an opening / closing body that can be easily opened and closed with respect to various bottles, mugs, etc.
