[0004] [Patent Document 1] Japanese Patent Application Publication No. 7-160944 Summary of the Invention [Problem to be solved by the invention]

[0005] However, if a beverage dispenser in which the top of the canister, including the lid, is exposed to the outside is installed in a location where it can be handled by many people, it may be necessary to provide a locking mechanism on the canister lid to prevent tampering, etc. Furthermore, when the device is installed in a place where only store clerks can handle it, such as behind a counter at a convenience store, a locking mechanism is often unnecessary. Therefore, the specifications of the beverage dispenser differ depending on whether or not it has a locking function, which causes problems for the beverage dispenser manufacturer, such as an increase in the number of parts. Also, for users who have installed the beverage dispenser, if the installation location of the device is changed after installation from a location where a locking mechanism is not required for the canister lid to a location where one is required, they will have to replace the canister or the entire device with a beverage dispenser with different specifications.

[0006] The present invention has been made in consideration of the above problems, and has an object to provide an ingredient canister for a beverage supply device in which the lid locking function can be easily changed with or without the use of the same part. [Means for solving the problem]

[0007] In order to solve the above problems, the raw material canister of the beverage supply device of the present invention is a raw material canister comprising a canister main body which is a container arranged on the top of the beverage supply device, has an opening, and stores raw materials, and a lid which covers the opening, and has a locking unit which is removably held on the lid, and the locking unit is held so that its mounting direction relative to the lid can be changed, and when the opening is covered by the lid, the mounting direction can be changed between a first specification in which the canister main body and the lid can be locked, and a second specification in which the mounting direction cannot be locked.

[0008] Alternatively, the raw material canister of the beverage supply device of the present invention is a raw material canister comprising a canister main body which is a container arranged on the upper part of the beverage supply device, has an opening and stores raw materials, and a lid which covers the opening, and has a locking unit which is removably held on the canister main body, and the locking unit is held so that its mounting direction relative to the canister main body can be changed, and when the opening is covered by the lid, the mounting direction can be changed between a first specification in which the canister main body and the lid can be locked, and a second specification in which the mounting direction cannot be locked. Effect of the Invention

[0009] According to the present invention, in the raw material canister of the beverage supply device, the locking unit is detachable from the lid or the canister body, and the presence or absence of the locking function can be changed by changing the mounting direction of the locking unit relative to the lid or the canister body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0012] FIG. 1 is a perspective view showing a schematic external shape of a coffee machine 1 (beverage supply device) equipped with a canister 10 (raw material canister) according to one embodiment of the present invention. FIG. 2 is a perspective view showing the external shape of the canister 10. FIG. 3 is a perspective view showing the structure of the canister 10 with the lid 11 removed. Note that in FIG. 3, a lock unit 20 provided on the lid 11 is additionally indicated at the position in a state in which the lid 11 is closed. Note that for convenience of explanation, the front-rear, left-right, top-bottom directions of the installed coffee machine 1 are used in FIGS. 1 to 3 and FIG. 4 onward which will be described later, and the canister 10 and the lid 11 described below will also be described using the directions in a state in which they are installed in the coffee machine. Particularly, FIGS. 4, 7, 9, 10, and 11 will be described using the front-rear, left-right, top-bottom directions in a state in which the lid 11 is closed.

[0013] As shown in FIG. 1, the coffee machine 1 is installed in, for example, a convenience store, and has a rectangular box-shaped main body 2 that is open at the front, and a main door 2a that closes the opening. The lower front portion of the main door 2a is provided with a base 3 on which a cup is placed, a cover 4 that covers the front side of the base 3 in an openable and closable manner, and a main door lock 2b. An operation panel 5 is provided above the base 3 on the front side of the main door 2a. In addition, the upper portion of the main body 2 is provided with a plurality of canisters 10 for storing ingredients for beverages such as coffee to be served in cups. The ingredients stored in the canisters 10 include a plurality of types of coffee beans, sugar, powdered milk, etc. In this embodiment, three canisters 10 are provided. Based on the operation of the operation panel 5, the coffee machine 1 produces a beverage such as coffee from ingredients stored in a canister 10, and serves the beverage in a cup placed on a mounting table 3.

[0014] 2 and 3, canister 10 has canister body 12, which is a generally rectangular box-shaped container long in the front-rear direction, and has an opening 13 at the top of canister body 12 for replenishing raw materials. A lower front part of canister body 12 is provided with outlet 15 for raw materials stored in canister 10. A lower part of canister 10 is provided with a motor-driven spiral (not shown), and the motor is driven based on the operation of operation panel 5 to discharge raw materials from outlet 15.

[0015] The canister 10 is provided at its upper portion with a lid 11 that covers the opening 13. The lid 11 is a substantially rectangular plate-shaped member that fits the opening 13 at the upper portion of the canister main body 12. The canister main body 12 and the lid 11 are formed of, for example, resin.

[0016] The lid 11 is detachable from the canister body 12, and is configured to be placed on the edge of the opening 13 of the canister body 12 to close the opening 13. Furthermore, lock units 20 are attached to the front and rear of the underside of the lid 11, which forms the inside of the canister 10. Note that in Fig. 3, the lock unit 20 is illustrated but the lid 11 is not, but this is for the purpose of explaining the position of the lock unit 20 when the opening 13 is closed by the lid 11, i.e., the locking position of the lid 11 by the lock unit 20.

[0017] Fig. 4 is a perspective view showing the structure of an attachment portion of the lock unit 20 in the cover 11 having a locking function. Fig. 5 is a perspective view showing the structure of the lock unit 20. Fig. 6 is a perspective view showing the structure of the lock unit 20, in which the front-rear direction of the lock unit 20 in Fig. 5 is inverted.

[0018] 4, a thin plate-like flange portion 21 is provided on the underside of the lid body 11, protruding downward, for example, by about 1 cm to 2 cm around the entire circumference near the outer circumferential end. The flange portion 21 is inserted into the opening 13 of the canister body 12 with almost no gap, and is configured so that when the lid body 11 closes the opening 13, the lid body 11 does not move in any direction.

[0019] The front and rear undersides of the lid 11 are provided with rectangular box-shaped retaining portions 23 into which the lock unit 20 is inserted. The flange portion 21 is cut out in a rectangular shape at the front left-right center and rear left-right center of the lid 11 to provide an insertion hole 24. The retaining portion 23 is disposed on the inner side of the insertion hole 24 in the front-rear direction. The lock unit 20 is inserted into the insertion hole 24 provided in the flange portion 21 of the lid 11 from the outside in the front-rear direction, and is held by the retaining portion 23 so that the lock unit 20 and the flange portion 21 overlap in the vertical position. Note that while FIG. 4 shows the front of the lid 11, the retaining portion 23 and the insertion hole 24 are also provided at the rear of the lid 11, and the lock unit 20 is inserted from the outside (rear side) and supported by the retaining portion 23, as in the front portion.

[0020] The lock unit 20 is formed of an elastic material such as resin. As shown in Figs. 5 and 6, the lock unit 20 is generally in the shape of a rectangular box, the left-right width of which is slightly smaller than the insertion hole 24, and has a first surface 20a and a second surface 20b which are parallel surfaces in the front-rear direction, and a spring portion 20c (urging portion) which connects the first surface 20a and the second surface 20b and is formed in a spring shape. The spring portion 20c has a function of urging the first surface 20a and the second surface 20b so as to move them away from each other in the front-rear direction. The first surface 20a is provided with a claw portion 27 which protrudes outward in the front-rear direction. The second surface 20b does not have the claw portion 27 and is flat.

[0021] A pair of locking portions 20d are provided, which extend from the left and right ends of the first surface portion 20a toward the second surface portion 20b on both left and right sides of the spring portion 20c. The locking portions 20d are each formed with a retaining projection 28 that projects outward in the left and right direction at approximately the center of the front-rear direction of the lock unit 20. The rear end of the locking portion 20d elastically swings about its front end, allowing it to move slightly in the left and right direction.

[0022] The holding portion 23 of the lock unit 20 provided on the underside of the lid 11 is formed in a box shape together with the underside 11a of the lid 11 so that the lock unit 20 can be inserted and held. The retaining portion 23 has a pair of side plate portions 23a extending inward from the left and right edges of the insertion hole 24 of the flange portion 21, a lower plate portion 23b extending parallel to the lower surface 11a of the lid body 11 between the lower ends of the side plate portions 23a, and an inner plate portion 23c extending vertically downward from the lower surface of the lid body 11 and connecting the pair of side plate portions 23a and the rear ends of the lower plate portion 23b.

[0023] The pair of side plate portions 23a are each provided with a holding hole 25 for supporting the holding protrusion 28 of the lock unit 20 inserted into the holding portion 23. Also, the inner plate portion 23c is provided with a hole 26. The retaining hole 25 and the hole portion 26 are each cut out around the lower plate portion 23b, and are sized so that the fingers of an operator (such as the manager of the coffee machine 1) can press the lock unit 20 retained in the retaining portion 23.

[0024] Fig. 7 is an explanatory diagram showing the mounting direction of the lock unit to the cover body having a locking function, and Fig. 8 is a vertical cross-sectional view showing the structure of the lock unit mounting portion of the cover body having a locking function.

[0025] As shown in Fig. 7, when the lock unit 20 is inserted into the insertion hole 24 from the second surface portion 20b side until it abuts against the inner plate portion 23c in the holding portion 23, the pair of holding protrusions 28 are each supported by the holding holes 25, as shown in Fig. 4, and the lock unit 20 is held in the holding portion 23 of the lid 11. At this time, the first surface portion 20a of the lock unit 20 is positioned approximately flush with the outer surface 21a of the flange portion 21 in the front-to-rear direction or slightly inward from the outer surface 21a, and the claw portions 27 of the first surface portion 20a are positioned so as to protrude outward from the outer surface 21a of the flange portion 21.

[0026] As shown in Figures 2, 3 and 8, an engagement hole 16 for the claw portion 27 of the locking unit 20 is provided in the upper part of the front wall 12a of the canister main body 12. When the opening 13 of the canister main body 12 is closed by the lid body 11, the claw portion 27 of the locking unit 20 engages with the engagement hole 16 of the canister main body 12, thereby locking the lid body 11 and the canister main body 12 together.

[0027] The claw portion 27 has a flat surface 27a that is perpendicular to the vertical direction on one side, and an inclined surface 27b that is inclined so that the vertical width decreases outward on the other side. If a locking mechanism is required for the lid 11 of the canister 10, the flat surface 27a faces upward and the inclined surface 27b faces downward when the lock unit 20 is attached to the lid 11. As a result, when the lid 11 is closed, the upper end of the front wall 12a comes into contact with the inclined surface 27b and the spring portion 20c is compressed, pushing the front part of the lock unit 20 inward, and the lid 11 can be easily closed. Furthermore, by attaching the flat surface 27a facing upward, even if an attempt is made to lift the lid 11 from the closed state, the flat surface 27a of the claw portion 27 is tightly locked with the locking hole 16, thereby preventing lifting. In order to ensure that the flat surface 27a faces upward when the lock unit 20 is attached to the lid 11, a groove 29 is provided on the lock unit 20 side and a protrusion 30 is provided on the lid 11 side.

[0028] In addition, it is preferable that the locking hole 16 is smaller than the tip of a finger, which makes it difficult to release the lock easily. By pushing the claw portion 27 of the lock unit 20, which is locked in the locking hole 16, inward with a rod-like object thinner than a fingertip, the claw portion 27 is released from the locking hole 16, the lock between the canister body 12 and the lid 11 is released, and the lid 11 can be lifted upward and opened.

[0029] Furthermore, the dimensions of the locking hole 16 should be, for example, slightly larger than the dimensions of a cross section perpendicular to the direction of insertion of the insertion portion of a key used to lock and unlock the main door lock of the coffee machine 1. This makes it possible to unlock the lid 11 using the key for the main door lock without having to prepare a special rod-shaped body, making it easier to maintain the coffee machine 1 and to replenish the canister with ingredients.

[0030] Also, when a rod-shaped body is inserted through the locking hole 16 to unlock the lid 11, the tip of the rod-shaped body comes into contact with the inclined surface 27b of the claw 27. When the rod-shaped body is further pushed in, the spring portion 20c bends and the front part of the lock unit 20 retreats, and when the flat surface 27a of the claw 27 comes out of the locking hole 16, the tip of the rod-shaped body presses the inclined surface 27b, generating an upward vector force against the claw 27. As a result, the lid 11 floats upward, and even if the rod-shaped body is pulled out, the claw 27 is pushed back forward by the return force of the spring portion 20c, and is maintained in the floated position due to friction between the tip of the claw 27 and the inner side of the upper edge of the front wall 12a. This makes it easier to hook the end of the lid 11 with your fingers, making it easier to open the lid 11.

[0031] In addition, the lock unit 20 held in the lid body 11 can be easily removed from the holding portion 23 of the lid body 11 by pushing the pair of holding protrusions 28 inward to release the engagement between the holding protrusions 28 and the holding hole 25, while pushing the second surface portion 20b of the lock unit 20 visible from the engagement hole 16 forward from the hole portion 26.

[0032] Fig. 9 is an explanatory diagram showing the mounting direction of lock unit 20 to cover 11 in cover 11 that does not require a locking function. Fig. 10 is a perspective view showing the structure of the lock unit mounting portion in cover 11 that does not require a locking function. Fig. 11 is a vertical cross-sectional view showing the structure of the lock unit mounting portion in cover 11 that does not require a locking function.

[0033] As shown in Fig. 9, even if the lock unit 20 is inserted into the insertion hole 24 from the first surface portion 20a side until it abuts against the inner plate portion 23c in the holding portion 23, the pair of holding protrusions 28 are each supported by the holding holes 25, and the lock unit 20 is held in the holding portion 23 of the lid body 11, as shown in Fig. 10. At this time, the claw portion 27 of the first surface portion 20a of the lock unit 20 is located inside the holding portion 23 of the lid body 11 (the inner plate portion 23c side), and the second surface portion 20b without the claw portion 27 is located approximately flush with the outer surface 21a of the flange portion 21 in the front-to-rear direction or slightly inward from the outer surface 21a.

[0034] Therefore, as shown in FIG. 11, when the opening 13 of the canister main body 12 is closed by the lid body 11, the lid body 11 and the canister main body 12 are not locked, and the lid body 11 can be easily lifted and removed from the canister main body 12 to open the opening 13 of the canister 10.

[0035] As described above, the canister 10 of this embodiment comprises the canister main body 12 and the lid 11 that covers the opening 13 at the top of the canister, and the lock unit 20 is removably provided on the lid 11. The lock unit 20 can be attached inverted relative to the lid 11, and can be changed between an attachment direction of a first specification in which the claws 27 are attached facing outward, and an attachment direction of a second specification in which the claws 27 are attached facing inward.

[0036] When the opening 13 is covered with the lid 11 of the first specification, the claws 27 are engaged with the locking holes 16 of the canister body 12, locking the canister body 12 and the lid 11. Therefore, the lid 11 cannot be easily removed from the canister body 12. This makes it possible to prevent foreign objects from being thrown into the canister 10 or raw materials from being taken out of the canister 10, for example, when the coffee machine 1 is installed in a location where it can be handled by many people.

[0037] When the opening 13 is covered with the lid 11 of the second specification, the claws 27 are not engaged with the locking holes 16 of the canister body 12, and the canister body 12 and the lid 11 are not locked together. Therefore, the lid 11 can be easily removed from the canister body 12 to open the opening 13 and replenish raw materials and the like into the canister body 12. For example, if the coffee machine 1 is installed in a place where only store staff can handle it, such as inside a counter at a convenience store, the lid 11 can be opened without performing an unlocking operation, and raw materials and the like can be easily replenished into the canister 10.

[0038] In this way, the canister 10 for the coffee machine 1 can be easily changed between a first specification in which the lid 11 is locked and a second specification in which the lid 11 is not locked, by changing the mounting direction of the lock unit 20. Therefore, the manufacturer of the coffee machine 1 can standardize parts between the first and second specifications, and can also standardize the specifications at the time of shipment.

[0039] Furthermore, for a user who has installed the coffee machine 1 in a store or the like, if the installation location is changed after installation from a location where a locking mechanism is not required for the lid 11 of the canister 10 to a location where one is required, the change can be made easily and at no cost without having to replace the canister 10 or the entire device with a beverage supply device with different specifications.

[0040] The lock unit 20 has a first surface 20a having a claw portion 27 protruding outward, and a second surface 20b which faces the first surface 20a and is a flat surface. By holding the first surface 20a facing outward on the holding portion 23 of the lid 11, the claw portion 27 protrudes outward from the insertion hole 24 of the lid 11, and the first specification can be configured in which the claw portion 27 can be locked in the locking hole 16 provided in the canister main body 12.

[0041] Furthermore, by holding the second surface portion 20b facing outward on the holding portion 23 of the lid body 11, a second specification can be configured in which the claw portion 27 does not protrude outward from the insertion hole 24 of the lid body 11 and the claw portion 27 cannot engage with the engagement hole 16 provided in the canister main body portion 12.

[0042] The lock unit 20 is made of resin, and the spring portion 20c that biases the first surface portion 20a and the second surface portion 20b in a direction separating them from each other is integrally formed with the first surface portion 20a and the second surface portion 20b. This allows the lock unit 20 to be constructed with a simple structure and at low cost. Also, by making the cover body 11 including the holding portion 23 and the lock unit 20 simply made of resin, it is possible to make them hygienic.

[0043] Furthermore, by having the spring portion 20c, when the first surface portion 20a is installed facing outward, the claw portion 27 can be biased in a direction to protrude outward, and when the claw portion 27 is engaged with the engagement hole 16, the claw portion 27 is less likely to come out of the engagement hole 16, thereby improving the locking performance of the lid body 11.

[0044] Furthermore, when the opening 13 is covered with the lid 11, the locking hole 16 in the front wall 12a of the canister main body 12 is closed by the first surface 20a of the locking unit 20 in the first specification, and by the second surface 20b of the locking unit 20 in the second specification. This makes it possible to prevent insects and other foreign objects from entering the canister main body 12 through the locking hole 16 in both the first and second specifications.

[0045] Furthermore, when unlocking the lid 11, it is possible to push the claw portion 27 exposed from the locking hole 16 inward, but the locking hole 16 is smaller than a fingertip. Therefore, it is not possible to unlock the lid 11 by pushing the claw portion 27 inward with a finger. This makes it difficult to remove the lid 11 by mischief, etc. Furthermore, when unlocking the lid 11, it is possible to push the claw portion 27 inward with something like a stick with a thin tip, but an administrator can store this separately from the coffee machine 1 to prevent others from unlocking the machine.

[0046] Furthermore, in the coffee machine 1 of this embodiment, the lock units 20 can be attached to the front and rear of the lid 11. For example, in the case where the front and rear lock units 20 are both of the first specification that can be locked, when one of the front and rear lock units 20 is released from locking, the other lock unit 20 functions like a hinge, and the unlocked side of the lid 11 can be lifted, and raw materials and the like can be replenished into the canister 10 from the lifted side. Therefore, if the installation position of the coffee machine is changed and raw materials, etc. are often replenished from the rear side of the canister, the locking unit 20 on the rear side of the lid body 11 can be released, the rear side of the lid body 11 can be lifted, and raw materials, etc. can be easily replenished into the canister 10 from the rear side.

[0047] Furthermore, the mounting directions of the lock units 20 on the front and back of the lid 11 can be different for the first specification and the second specification. For example, when the coffee machine 1 is installed in a convenience store, beverages may be served to consumers from the front, while ingredients are replenished into the canisters 10 by a store clerk from the rear. In such a case, it is preferable that the lid 11 cannot be easily opened from the front, but can be easily opened from the rear, and in this embodiment this can be easily achieved by making the front side the first specification and the rear side the second specification. In this embodiment, the lock unit 20 can be attached to the front or back of the lid body 11, but the lock unit 20 may be attached to either the front or back of the lid body 11, and the other may not be attached by, for example, providing a fixed claw portion (convex portion) on the flange portion 21 at the position where the claw portion 27 is located and engaging it with the engaging hole 16.

[0048] The present invention is not limited to the above embodiment. For example, in the above embodiment, the lock units 20 are attached to the front and rear of the lid 11, but the present invention may be applied to a configuration in which the canister body 12 and the lid 11 are connected by a hinge so as to be able to open and close, and the lid 11 is fixed to the canister body 12 by one lock unit 20.

[0049] In the above embodiment, the lock unit 20 is configured to be detachable from the lid 11, but the lock unit 20 may be configured to be detachable from the canister body 12. In this case, the canister body 12 is provided with a portion such as a holding portion 23 for holding the lock unit 20, and the lock unit 20 can be attached to the holding portion of the canister body 12 by inverting it. Furthermore, the lid 11 is provided with a locking hole 16 that can lock the claw portion 27 of the lock unit 20. For example, when the lid 11 covers the opening 13 of the canister body 12, the flange portion 21 of the lid 11 is positioned outside the edge of the opening 13 of the canister body 12, and the locking hole 16 may be provided in the flange portion 21. As a result, by changing the mounting direction of the lock unit 20 (mounting it inverted), as in the above embodiment, the lid 11 can be easily switched between a first specification in which the lid 11 can be locked and a second specification in which the lid 11 cannot be locked.

[0050] In addition, in this embodiment, the present invention is applied to the canister 10 used in the coffee machine 1, but the present invention is not limited to coffee machines and may be applied to containers such as canisters or hoppers with lids used in various beverage supply devices and machines for various purposes. In this embodiment, in addition to the above-mentioned configuration in which the lock is released by inserting a rod-shaped object thinner than a fingertip through the locking hole 16 and pushing the claw portion 27 inward, the lock may be released by a cylinder lock arranged at approximately the same position as the locking hole 16. For example, the locking hole 16 may be provided at the back (inner side of the canister) of the cylinder lock arranged at approximately the same position as the locking hole 16, and the lock unit 20 may be arranged so as to be attachable at a position inward of the flange portion 21 so that the claw portion 27 engages with the locking hole 16.
