Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in a conventional water bottle as described in Patent Document 1, while the attachment and detachment to the water bottle body can be easily performed by screw connection, a third party other than the owner of the water bottle can also open and close the bottle. Therefore, there is a risk that the content will be consumed without permission and that foreign matter will be mixed into the water bottle, and problems such as ensuring hygiene and the safety of the content cannot be solved.

[0005] In addition, in a conventional water bottle, when vibration or impact is applied, for example, when the tightening of the rotary cap to the water bottle body is loose, the rotary cap may unexpectedly move in the opening direction. In such a case, there is also a problem that the content stored in the water bottle body leaks to the outside.

[0006] In view of these points, it can be said that the conventional water bottle has not been considered at all from the viewpoint of preventing unauthorized and unexpected opening, and thus there is still room for improvement.

[0007] The present invention aims to provide a water bottle that can prevent unauthorized and accidental opening. [Means for solving the problem]

[0008] The water bottle according to the present invention comprises a water bottle body having a mouth and a rotating cap capable of closing the mouth, and is provided on either the water bottle body or the rotating cap with a locking device that restricts the movement of the rotating cap closing the mouth in the opening direction.

[0009] Preferably, the locking device includes a retractable member that is movably fitted into a mating portion provided on the water bottle body and the other rotating cap, and a dial lock that holds the retractable member fitted into the mating portion so as not to move.

[0010] Preferably, the dial constituting the dial lock is provided such that its entire outer surface protrudes from the outer surface of the water bottle body along the circumferential direction of the water bottle body.

[0011] Preferably, the rotating cap has a rotating cap body having an opening that communicates with the mouth and is detachably connected to the water bottle body; a flip lid supported on the rotating cap body so as to be able to open and close; a locking means for locking the flip lid to the rotating cap body and holding the flip lid closed; and a pressing operation part that is movable between a holding position for holding the rotating cap body and the flip lid locked by the locking means and a release position for releasing the locked state, and the locking device has a holding member provided on the rotating cap that holds the pressing operation part in the holding position while the reciprocating member is held immovably by the dial lock. [Effects of the Invention]

[0012] According to the present invention, it is possible to reliably prevent unauthorized and accidental opening of a bottle cap, even with a relatively simple configuration. [Brief explanation of the drawing]

[0014] Embodiments of the present invention will be described below with reference to the drawings. The same reference numerals are used for the same elements in all drawings, and redundant explanations are omitted.

[0015] Figure 1 is a schematic diagram showing an overview of the water bottle according to this embodiment, and Figure 2 is a bottom view of the rotating cap that constitutes the water bottle in Figure 1. Figure 3 is an exploded perspective view of the locking device that constitutes the water bottle in Figure 1, and Figure 4 is an explanatory diagram for explaining the operation of the retractable member and dial lock that constitute the locking device in Figure 3. Note that the vertical direction in the following explanation corresponds to the vertical direction of the water bottle 1 shown in Figure 1.

[0016] <Overall configuration of water bottle 1> As shown in Figure 1, the water bottle 1 according to this embodiment is a container that can be carried while containing contents such as drinking water, and is composed of a water bottle body 10, a rotating cap 20, and a locking device 30.

[0017] (Water bottle body 10) The water cylinder body 10 includes a storage part 11 capable of storing contents and a mouth part 12 to which a rotary cap 20 can be attached. Note that the water cylinder body 10 can be formed using a metal member (for example, stainless steel), a resin member, or the like, similar to the water cylinder body constituting a known water cylinder.

[0018] The storage part 11 is formed in a substantially cylindrical shape and has an upper surface part 11A having a flat annular shape, a cylindrical hole part 11B extending downward from the upper surface part 11A, and a storage space S capable of storing contents. The cylindrical hole part 11B is a non-penetrating hole, and a retractable member 31 constituting a locking device 30 is arranged inside thereof in a manner that allows it to protrude and retract (see FIG. 3 and the like). A detailed description of the retractable member 31 will be given later.

[0019] The mouth part 12 has a substantially cylindrical shape and stands upright from the upper surface part 11A in a state of being in communication with the storage space S of the storage part 11. On the outer peripheral surface of the mouth part 12, a male screw part 12A that can be screwed with a female screw part 21 of the rotary cap 20 described later is formed.

[0020] (Rotary cap 20) As shown in FIGS. 1 and 2, the rotary cap 20 is a member for closing the mouth part 12 of the water cylinder body 10. The rotary cap 20 according to the present embodiment has its main body part formed in a bottomed cylindrical shape and has a female screw part 21, a bottom surface part 22, a concave groove 23, and a packing 24. Note that the main body part of the rotary cap 20 can be formed using a resin member or the like, similar to the rotary cap constituting a known water cylinder.

[0021] The female screw part 12A is formed on the inner peripheral surface of the rotary cap 20 and has a shape that can be screwed with the male screw part 12A of the water cylinder body 10. The bottom surface part 22 has a wide annular shape and is formed in a flat shape.

[0022] The groove 23 has a hollow dome shape and is formed at a predetermined position on the bottom surface 22. Specifically, the groove 23 is formed at a position that aligns with the cylindrical hole 11B of the water bottle body 10 when the rotating cap 20 is attached to the water bottle body 10. As will be described in detail later, in this embodiment, when the rotating cap 20 is attached to the water bottle body 10, the retractable member 31, which is mounted to be able to move in and out of the cylindrical hole 11B, is configured to be fitted into the groove 23.

[0023] The packing 24 is a component that prevents the contents contained in the storage space S from leaking out when the rotating cap 20 is attached to the water bottle body 10. The packing 24 has an annular shape and is attached to the upper side of the flat inner surface (see Figure 2). Note that the packing 24 is not limited to being formed in an annular shape, but can also be formed in other shapes, such as circular.

[0024] (Locking device 30) As shown in Figures 1, 3, and 4, the locking device 30 includes a retractable member 31, a biasing member 32, and a dial lock 33.

[0025] The retractable member 31 is a member that is positioned to extend and retract freely within the cylindrical hole 11B (see Figure 1) of the water bottle body 10, and has a rod-shaped portion 31A, a spherical portion 31B, a flange portion 31C, and a notched recess 31D. Such a retractable member 31 can be formed using a metal member, a resin member, or the like.

[0026] As shown in Figure 3, the retractable member 31 is positioned close to the inner edges of the dials 33A to 33C that constitute the dial lock 33 (see Figure 4). A detailed explanation of the dials 33A to 33C will be given later.

[0027] The rod-shaped portion 31A is formed in an elongated cylindrical shape, and a spherical portion 31B, which is formed in a spherical shape, is provided at its upper end. In this embodiment, a reciprocating member 31 with a spherical portion 31B is used, but instead, for example, a reciprocating member in which the upper end of the rod-shaped portion 31B is formed in a curved surface shape (a reciprocating member in which the spherical portion 31B is omitted) can be used.

[0028] The flange portion 31C has an annular plate shape and is provided to protrude from the outer circumferential surface on the lower end side of the reciprocating member 31. The flange portion 31C functions as a stopper to prevent the biasing member 32 (in this embodiment, a "coil spring"), which is externally fitted to the lower end side of the reciprocating member 31, from moving any further toward the upper end of the reciprocating member 31. In this embodiment, the flange portion 31C is used as a configuration to restrict the movement of the biasing member 32, but other configurations (for example, a groove portion) can also be used.

[0029] Now, let's explain the biasing member 32. The biasing member 32 is a member that biases the reciprocating member 31, which is located inside the cylindrical hole 11B (see Figure 1) of the water bottle body 10, upward. In this embodiment, a coil spring as shown in Figure 3 is used as the biasing member 32, but other types of springs may also be used.

[0030] The biasing member 32 is configured to be positioned inside the cylindrical hole 11B of the water bottle body 10, with the biasing member 32 externally fitted to the lower end of the retractable member 31. The biasing member 32 is positioned, for example, in a state where it is narrowed between the bottom of the cylindrical hole 11B of the water bottle body 10 (not shown) and the flange 31C of the retractable member 31, thereby enabling the retractable member 31 to be biased upward.

[0031] The retractable member 31 is positioned so that, when biased by the biasing member 32, the spherical portion 31B protrudes by a predetermined amount (for example, about 1 / 5 to 1 / 4 of the diameter of the spherical portion 31) from the upper surface 11A of the water bottle body 10.

[0032] As shown in Figures 3 and 4, the notched recess 31D has a roughly crescent shape in cross-section and is formed on the outer circumferential surface of the rod-shaped portion 31A. Multiple notched recesses 31D are formed, spaced apart from each other in the vertical direction, corresponding to the number of dials (three in this embodiment) which will be described later. The height of the notched recess 31D in the vertical direction is set to be slightly larger than the axial width of the dials 33A to 33C.

[0033] The notched recess 31D configured in this way is positioned so that it can engage with the inner surfaces of the dials 33A to 33C, which will be described later, when the retractable member 31 and the dial lock 33 are assembled (see Figure 4(b)). As will be described in detail later, in this embodiment, when at least one of the multiple notched recesses 31D is engaged with the dials 33A to 33C, the downward movement of the retractable member 31 is restricted.

[0034] The dial lock 33 has multiple dials (in this embodiment, "three" dials 33A to 33C). Each dial is formed in an annular shape, with multiple numbers engraved on its outer surface (see Figure 1), and a notched recess 33a with a substantially semicircular cross-section is formed on its inner surface.

[0035] The dial lock 30 itself has a configuration similar to a well-known dial lock (a so-called combination lock (fixed number type)), so a detailed explanation will be omitted, but in this embodiment as well, When all dials 33A to 33C are in a predetermined unlocking position (for example, positions "4", "6", and "4" from the top (see Figure 1)), the inner periphery of each dial and the notched recess 31D of the retractable member 31 are not engaged, allowing the retractable member 31 to be moved downward (see Figure 4(a)). If at least one of the multiple dials 33A to 33C is not in the unlocked position (for example, if it is in the positions "4", "6", and "4" from the top, see Figure 1; hereafter, this position will be referred to as the "locked position"), the inner periphery of the dial and the notched recess 31D of the retractable member 31 will engage, making it impossible to move the retractable member 31 downwards (see Figure 4(b)). It is configured as such. In this embodiment, three dials are provided to constitute the dial lock 30, but there may be two or fewer, and it is also possible to have four or more.

[0036] <How to use water bottle 1> Next, the method of using the water bottle 1 according to this embodiment will be explained with reference to Figures 1 to 4. In the following, we will describe the state before using water bottle 1. - The storage space S of the water bottle body 10 is empty (the water bottle body 10 is empty). • All dials of the dial lock 33 are in the unlocked position. This will be explained under the condition that...

[0037] As shown in Figure 1, the method of using the water bottle 1 according to this embodiment begins with filling the contents into the mouth 12 of the water bottle body 10, similar to known water bottles. Subsequently, the rotating cap 20 can be attached to the water bottle body 10 by screwing the female threaded portion 21 of the rotating cap onto the male threaded portion 12A of the water bottle body 10 and tightening it. In this embodiment, in this state, the packing 24 (see Figure 2) of the rotating cap 20 is configured to be in close contact with the upper surface 12B of the water bottle body 10, thereby preventing leakage of the contents contained in the storage space S.

[0038] At this time, when all dials 33A to 33C are in the unlocked position, the notched recess 31D of the retractable member 31 and the inner periphery of the dial are not engaged (see Figure 4(a)), so it is possible to move the retractable member 31 downward against the biasing force of the biasing member 32. In other words, in this embodiment, by positioning all dials 33A to 33C in the unlocked position, the rotating cap 20 can be moved in the opening direction, making it possible to drink or otherwise consume the contents contained in the storage space S.

[0039] On the other hand, in this embodiment, when at least one of the dials 33A to 33C is in the locked position, the inner periphery of the dial is configured to fit into the notched recess 31D of the retractable member 31 (see Figure 4(b)).

[0040] In other words, in this embodiment, by moving at least one of the dials 33A to 33C to the locked position, the reciprocating member 31 can be locked (made immobile) with the spherical part 31B fitted into the groove 23, making it impossible or difficult to move the rotating cap 20 in the opening direction.

[0041] <Configuration and Effects of the Embodiment> As described above, the water bottle 1 according to this embodiment comprises a water bottle body 10 having a mouth 12 and a rotating cap 20 capable of closing the mouth 12, and includes a locking device 30 provided on the water bottle body 10 that restricts the movement of the rotating cap 20 that closes the mouth 12 in the opening direction. With this configuration, the water bottle 1 according to this embodiment can be prevented from being opened improperly, and it is possible to prevent situations in which the contents stored in the storage space S of the water bottle body 10 unexpectedly leak out.

[0042] Furthermore, the locking device 30 is provided on the water bottle body 10 and includes a retractable member 31 that is fitted into a groove 23 formed in the rotating cap 20 so as to be able to move back and forth, and a dial lock 33 that holds the retractable member 31 fitted into the groove 23 so as not to move. With this configuration, the locking device 30 can be locked and unlocked without using a key.

[0043] Furthermore, the dials 33A to 33C that constitute the dial lock 33 are provided so that their entire outer surfaces protrude from the outer surface of the water bottle body 10 along the circumferential direction of the water bottle body 10. Because of this configuration, the dials 33A to 33C can be rotated while being pinched with multiple fingers (for example, the thumb and index finger), thereby improving operability and providing a water bottle 1 with superior aesthetic design.

[0044] <Variation> In the water bottle 1 according to the above embodiment, the locking device (locking device 30) is provided on the water bottle body (water bottle body 10) side, but it can also be provided on the rotating cap side, as shown in the water bottle 101 in Figure 5. Such a water bottle 101 will be described below with reference to Figures 5 and 6.

[0045] Figure 5 is a schematic diagram showing an overview of a modified water bottle, and Figure 6 is an explanatory diagram illustrating the operation of the movable parts and locking device that constitute the water bottle in Figure 5. In the following explanation, the vertical direction corresponds to the vertical direction of the water bottle 101 shown in Figure 5.

[0046] <Overall configuration of water bottle 101> As shown in Figure 5, the water bottle 101 according to this modified example is configured to include a water bottle body 110, a rotating cap 120, and a locking device 130, similar to the water bottle 1 according to the above embodiment (see Figure 1).

[0047] (Water bottle body 110) The water bottle body 110 comprises a storage section 111 having a storage space S and a mouth section 112 having a male screw section 112A. Compared with the water bottle body 10 (see Figure 1) of the water bottle 1 according to the above embodiment, the modified water bottle body 110 is - The upper surface portion 111A of the housing portion 111 is formed in a flat shape. • A dome-shaped recessed area 111B is formed on the upper surface portion 111A. The only difference is the configuration, which is otherwise the same. For the sake of clarity, detailed explanations of the configurations similar to those of the aforementioned water bottle body 10 will be omitted below, except where necessary.

[0048] The fitting recess 111B is formed in a position into which the fitting projection 131E, which protrudes from the bottom surface of the rotating cap 120, fits when the rotating cap 120 is attached to the water bottle body 110. A detailed explanation of the fitting projection 131E will be given later.

[0049] (Rotating cap 120) The rotating cap 120 comprises a rotating cap body 121 and a flip cover 122 that is attached to the rotating cap body 121 via a shaft portion 123 so as to be able to open and close. Although not shown in the figures, a biasing member (for example, a torsion spring) is attached to the shaft portion 123, etc., to bias the flip cover 122 in the opening direction. This makes it possible to move the flip cover 122 to the open position with a single touch, similar to known flip covers.

[0050] The rotating cap body 121 has a female threaded portion (not shown) that can be screwed into the male threaded portion 112A of the water bottle body 110, and a nozzle 121A.

[0051] The nozzle 121A is configured to communicate with the mouth 112 when the rotating cap 121 is attached to the water bottle body 110, and it is possible to pour out the contents contained in the storage space S from the opening 121B formed at the upper end.

[0052] The movable body 124 is pivotably attached to the rotating cap body 121 via the shaft portion 125 on the side opposite to the side to which the shaft portion 123 is attached (see Figures 5 and 6).

[0053] The movable body 124 is formed in the shape of a rectangular plate and has a locking claw 124A formed on its upper end and a pressing operation part 124B provided on its lower end.

[0054] The movable body 124 is biased outward at its lower end (pressing operation portion 124B) by a biasing member 132 attached to the rotating cap body 121 (see Figure 6). Although a coil spring is shown as the biasing member 132 in the drawing, other biasing members, such as a torsion spring, can also be used.

[0055] The locking claw 124A is the part that engages with the engaging claw 122A of the flip cover 122, which will be described later. The locking portion 124A is configured to engage with the engaging claw 122A when the flip cover 122 is moved to the closed position that closes the nozzle 121A (opening 121B), thereby restricting the movement of the flip cover 122 in the opening direction (see Figures 5 and 6(a)).

[0056] The pressing operation part 124B is used to release the engagement between the engaging claw 122A and the locking claw 124A. Specifically, in this embodiment, the engagement between the engaging claw 122A and the locking claw 124A can be released by pressing the pressing operation part 124B while they are engaged (see Figures 5 and 6(b)).

[0057] On the inner surface of the flip cover 122, an engaging claw 122A is provided on the side opposite to the side to which the shaft portion 123 is attached, which can engage with the locking claw 124A of the movable body 124. Although not shown in the figures, a packing is provided on the upper inner surface of the flip cover 122 that closes the nozzle 121A (opening 121B) of the rotating cap 120 when the flip cover 122 is moved to the closed position. This prevents the contents contained in the storage space S from leaking out of the nozzle 121A when the flip cover 122 is in the closed position.

[0058] As shown in Figures 5 and 6, the locking device 130 comprises a retractable member 131, a biasing member 132, a dial lock 133, and a holding member 134. Note that the locking device 130 according to this modified example is different from the locking device 30 according to the above embodiment (see Figures 3 and 4, etc.). The retractable member 131 is biased downward by the biasing member 132. The retractable member 131 is provided with a rod-shaped portion 131A, a spherical portion 131B, a flange portion 131C, and a notched recess 131D, as well as a fitting projection 131E. • The retaining member 134 is provided. Since the configuration differs in some aspects, and other configurations (for example, the mechanism for locking and unlocking using the dial lock 133 (dials 133A to 133C)) are similar, a detailed explanation of a configuration similar to the aforementioned locking device 30 will be omitted unless necessary.

[0059] The retractable member 131 has a rod-shaped portion 131A, a spherical portion 131B, a flange portion 131C, and a notched recess 131D, as well as a fitting projection 131E that protrudes downward from the spherical portion 131B. The fitting projection 131E has a curved tip and is positioned to protrude from the bottom surface of the rotating cap body 121 when the retractable member 131 is biased downward by the biasing member 132.

[0060] Furthermore, the fitting projection 131E is positioned to fit into the fitting recess 111B formed on the upper surface 111A of the water bottle body 110 when the rotating cap 120 is attached to the water bottle body 110.

[0061] In the water bottle 101 configured in this way, after attaching the rotating cap 120 to the water bottle body 110, the retractable member 131 that fits into the fitting recess 111B can be locked by positioning at least one of the dials 133A to 133C in the locked position. Therefore, in this modified water bottle 101, just like the water bottle 1 according to the above embodiment (see Figure 1, etc.), it is possible to prevent unauthorized and accidental opening.

[0062] As shown in Figure 6, the locking device 130 according to this embodiment includes a retractable member 131, a biasing member 132, and a dial lock 133, as well as a retaining member 134 formed in the shape of a plate or a rod.

[0063] The retaining member 134 has one end that contacts the inner surface of the pressing operation part 124B and a tapered other end (see "Tapered surface 134A" in Figure 6) that contacts the lower end of the spherical part 131B, and is provided to be horizontally movable. Such a retaining member 134 can be formed using a metal member, a resin member, or the like. The other end of the retaining member 134 (the tip of the tapered surface 134) is positioned near the lower center of the spherical part 131B when the pressing operation part 124B is not being pressed (see Figure 6(a)).

[0064] In this modified configuration, when the pressing operation part 124B is pressed, the pressing force is transmitted to the spherical portion 131B of the reciprocating member 131 via the holding member 134. Specifically, when the pressing operation part 124B is pressed, the holding member 134 is configured such that the tapered surface 134A slides on the outer surface of the spherical portion 134B, pushing up the spherical portion 134B. This makes it possible to move the reciprocating member 132 upward against the biasing force of the biasing member 132 (see Figure 6(b)).

[0065] On the other hand, in this modified example, as described above, when at least one of the dials 133A to 133C of the locking device 130 is positioned in the locked position, the retractable member 131 is locked (its upward movement is restricted). In such a case, In addition to maintaining the fitted state between the fitting recess 111B (see Figure 1) and the fitting projection 131E, • The pressing operation part 124B cannot be pressed. It is designed that way.

[0066] In other words, in this modified example, by positioning at least one of the dials 133A to 133C in the locked position, • Similar to the above embodiment, in addition to restricting the movement of the rotating cap 120 in the opening direction, The opening of the flip cover 122 is also restricted. It is configured in this manner. Furthermore, the rotation cap 120 can be moved in the opening direction, and the flip cover 122 can be opened by positioning all of the dials 133A to 133C of the locking device 130 in the unlocked position.

[0067] <Structure and Effects of the Modified Example> As described above, the water bottle 101 according to this modified example has a rotating cap 120 which has a nozzle 121A (opening 121B) that communicates with the mouth 112 and a rotating cap body 121 which is detachably connected to the water bottle body 110, a flip lid 122 which is supported on the rotating cap body 121 so as to be able to open and close, a locking claw 124A which locks the flip lid 122 to the rotating cap body 121 and holds the flip lid 122 closed, and a pressing operation part 124B which is movable between a holding position which maintains the locked state of the rotating cap body 110 and the flip lid 122 by the locking claw 124A and a release position which releases the locked state, and a locking device 130 which has a holding member 134 provided on the rotating cap body 121 which holds the pressing operation part 124B in the holding position when the advancing member 131 is held immovably by the dial lock 133. Because of this configuration, in the modified water bottle 101, when the retractable member 131 is locked by the locking device 130, the movement of the rotating cap 120 relative to the water bottle body 110 in the opening direction is restricted, and the pressing operation of the pressing operation part 124 (movement of the flip lid 122 in the opening direction) is also restricted. Therefore, according to this modified design, even if the rotating cap is a flip-type that opens with a single touch, it cannot be opened improperly, and it is possible to prevent the contents stored in the storage space S of the water bottle body 110 from unexpectedly leaking out.

[0068] The embodiments described above are not intended to limit the present invention, and any modifications that do not depart from the spirit of the invention are included within the scope of the rights of the present invention.

[0069] For example, in the above embodiment and its modifications, a dial lock was used as the locking device, but other locking devices, such as a locking device using a key, can also be used.

[0070] Furthermore, the structure, method, etc., of the present invention can be modified in various ways without altering the essence of the invention.
