Description

The present invention relates to a shaker suitable for use, for example, in order to mix an appropriate amount of a thickening agent into a drink or the like to be served to a person with a swallowing disorder.

When adding a thickening agent to food and drink for people with dysphagia (water, tea, miso soup, etc.) for the purpose of preventing aspiration, etc., place the measured amount of food and drink and the thickening agent into a container such as a cup or sucker, and use a spoon. It is common to stir with

In the above method, the contact area between the spoon and the food/drink, etc. (food/beverage and thickening agent) is limited, and if the spoon is moved violently, the food/drink, etc. will spill, so the food/beverage and the thickening agent are It takes time for the mixture to become mixed.

Therefore, it is conceivable to use a shaker for the thickening work. If you put food or drink into the shaker and shake it with the lid closed, you can move the entire shaker vigorously without worrying about the food or drink spilling, and you can expect a reduction in work time.

However, when the present inventors investigated methods using a shaker, it was found that when the food and drink are at high temperature, the contents may squirt out when the lid of the shaker is opened after shaking. This phenomenon is thought to be caused by the fact that the air inside the shaker is warmed by the heat of the food and drink, and the internal pressure increases due to thermal expansion.

The present invention has been made with the above-mentioned considerations in mind, and its purpose is to quickly perform mixing operations such as thickening operations, while suppressing the occurrence of the gushing phenomenon even when the object to be mixed is at a high temperature. Our goal is to provide shakers that can.

In order to achieve the above object, the shaker according to the present invention is a shaker in which a lid on a hollow body can be freely opened and closed, and is shaken in a closed state in order to mix the materials put into the internal space. The shaker comprises a ventilation hole that communicates the internal space with an external space, and a valve that closes the ventilation hole, and the ventilation hole is opened when the valve is pressed toward the inside of the shaker. (Claim 1).

In the above shaker, the vent hole and the valve may be provided in the lid (Claim 2).

In the shaker described above, a measuring means may be provided on the lid (Claim 3).

The present invention provides a shaker that can quickly perform mixing operations such as thickening operations, while also suppressing the occurrence of the gushing phenomenon even when the object to be mixed is at a high temperature.

That is, in the shaker of the invention according to each claim of the present application, by putting the object to be mixed into the shaker and shaking it, the mixing operation can be performed quickly. In addition, even if the material put inside the shaker is hot and the air warmed by the shaking action expands thermally and increases the internal pressure, the valve can be pushed inward to the shaker and the air vented to the outside through the open vent. By letting it escape, the occurrence of the gushing phenomenon can be suppressed.

If the vent hole and the valve are provided on the main body side, there is a risk that the material may leak from the open vent hole depending on the location where the vent hole and the valve are provided and the amount of material in the internal space. In the shaker of the invention according to claim 2 provided, such leakage can be prevented.

In the shaker of the invention according to claim 3, since the measuring means provided on the lid can measure the thickening agent, etc., there is no need for a separate measuring spoon, etc., and the number of devices required for mixing is reduced accordingly, which saves labor in cleanup work. It is possible to aim for In addition, by keeping the lid's measuring means facing the inner space of the main body when the lid is closed, even if some of the mixture measured by the measuring means remains on the surface of the measuring means, it can be shaken. Since the mixture is brought into contact with other objects to be mixed that move along with the movement, better mixing is ensured.

It is a perspective view of the ventilation hole of the said ventilation part. (A) and (B) are a perspective view and a partially enlarged perspective view showing the structure of a modified example of the shaker. It is an explanatory view showing the composition of the modification of the above-mentioned ventilation part. (A) to (C) are an explanatory view showing an enlarged lower part of the main body, a perspective view from the bottom side, and a bottom view.

Embodiments of the present invention will be described below.

The shaker S shown in FIG. 1(A) has a hollow cylindrical body 1 with a bottom (see also FIGS. 1(D) and (E)), and a lid that can be opened and closed with respect to the body 1 (attached and detached from the mouth portion 1a). 2 (see also FIGS. 1(B) and (C)), and in order to mix the materials (to be mixed) put into the internal space, a shaking operation is performed in the closed state (with the lid 2 closed). It is something that will be done.

Examples of the materials (to be mixed) to be put into the internal space of the shaker S include food and drink (water, tea, miso soup, etc.) and a thickening agent for adding a thickening agent to the food, but the materials are not limited to these. First, the shaker S of this example can mix various materials.

As shown in FIGS. 1(D) and (E), the side wall of the main body 1 is provided with a measuring scale (measuring means) 3 for measuring the material put into the main body 1, and in the illustrated example, Scales indicating 50 to 300 ml are provided at 50 ml intervals. Note that the main body 1 in this example is molded from a material such as transparent or translucent resin, and the measuring scale 3 is provided on the outer surface of its side wall; however, the present invention is not limited to this; for example, the main body 1 may be molded from an opaque material. , the measuring scale 3 may be provided on the inner surface of the side wall.

As shown in FIGS. 1D and 1E, the main body 1 is also provided with a handle 4 that projects laterally from the upper part of the outer surface of the side wall and extends downward. The handle 4 is thick enough to be easily grasped even by people who have some difficulty in hand movements such as grasping or gripping objects, and is long enough to be supported by the entire palm of the hand. Specifically, the length L of the handle 4 (see FIG. 1(E)) is set to 70 to 80 mm. Here, the length L refers to the distance from the highest position on the lower surface of the base end of the handle 4 to the lower end of the handle 4. Furthermore, the thickness T (see FIG. 1(E)) of the thickest part 4a of the handle 4 is 10 to 15 mm, and the width W (see FIG. 1(D)) is 15 to 20 mm. It extends continuously up and down over a range of about half or more of the length L.

Moreover, as shown in FIG. 1(E), the lower part 4b of the handle 4 (the part below the thickest part 4a) extends further away from the outer surface of the side wall of the main body 1 as it goes lower. This makes it easier to insert your hand between the handle 4 and the outer surface of the side wall of the main body 1 and grasp the handle 4.

Here, if the material put into the main body 1 is at a low temperature below freezing or a high temperature above 80°C, when you hold the side surface (outer surface of the side wall) of the main body 1 with your hand, the coldness or heat of the material will be felt in your hand. However, in the shaker S of this example, such pain can be avoided or alleviated by having the handle 4 to which heat is relatively difficult to be transmitted.

As shown in FIGS. 1(A), (D), and (E), the lower part of the main body 1 has an overhanging part 5 that extends, for example, about 10 to 15 mm in the form of a flange to the sides of the main body 1 over its entire circumference. It is provided. The projecting portion 5 is inclined so that the outer side thereof is positioned downward, and the lower end of the projecting portion 5 is located below the bottom surface of the main body 1.

By providing the projecting portion 5 at the lower part of the main body 1 in this way, an advantage is obtained that the main body 1 placed on a table or the like is less likely to fall over.

Furthermore, so that the overhang 5 functions as a so-called cutting platform, a groove 6 (see FIGS. 6(A) to 6(C) ), the main body 1 placed on the table with the hot mixture to be mixed will slide on the table due to the expansion of the air sealed between the overhang 5 and the table. This can be prevented. Note that the number of grooves 6 may be plural or single, and in the case of plural grooves 6, it is possible to arrange the grooves 6 at equal intervals in the circumferential direction of the overhanging portion 5. In the illustrated example, three grooves 6 are arranged at equal intervals in the circumferential direction of the projecting portion 5, so that the main body 1 stands at three points (three legs), thereby increasing its posture stability.

On the other hand, the lid 2 has a substantially circular shape in plan view, as shown in FIG. 1(C), and has an opening 1a (FIG. 1(D) and (E)) in the closed state, the main body 1 is configured to protrude laterally over the entire circumference from the upper part (mouth portion 1a) of the main body 1.

When the lid 2 closes (closes) the opening 1a of the main body 1, the lower surface of its peripheral edge comes into contact with the opening 1a. The fitting part 13 has a substantially cylindrical fitting part 13 (see FIGS. 1(B) and (C)), and an annular packing (not shown) is removably attached to the outer peripheral surface of the fitting part 13. A groove 15 is formed. This packing is preferably molded from a material such as silicone rubber, which has durability and wear resistance that does not easily deteriorate even when exposed to steam, hot water, detergents, etc. for a long period of time.

In addition, in this example, as shown in FIG. 1(B), a notch 13a is provided at a portion of the fitting portion 13 on the distal side of the annular groove 15, so that the packing attached to the annular groove 15 can be easily removed. be.

On the other hand, as shown in FIGS. 1(B) and (C), L-shaped claws 16 are formed at two locations 180° apart from each other on the outer circumferential side of the contact portion on the lower surface of the peripheral edge of the lid 2. By rotating the lid 2 around its axis with the fitting part 13 inserted into the mouth part 1a of the main body 1, the two L-shaped claws 16 are connected to the two engaging protrusions 17 on the upper outer surface of the side wall of the main body 1. (See FIGS. 1(D) and (E)). In this state, the lid 2 is in a closed state sealing the main body 1. As shown in FIGS. 1(B) and 1(C), a total of two rotational operation protrusions 8a are provided at positions 90° out of phase with the L-shaped pawl 16 on the side surface of the peripheral edge of the lid 2. Rotation of the lid 2 becomes easy by hooking a finger on the lid 2. Therefore, it is preferable that the rotation operation protrusion 8a has an appropriate size.

Here, as shown in FIG. 1(D), each engagement protrusion 17 is provided with a stopper part 17a that is longer in the vertical (up and down) direction than the L-shaped claw 16, and the L-shaped claw 16 is attached to the stopper part 17a. Once abutted, the lid 2 will be unable to rotate any further, allowing the user to recognize that the engagement is complete. Further, a tapered guide portion 17b extending in the circumferential direction along the outer peripheral surface of the main body 1 is provided on the upper part of the stopper portion 17a, thereby making it easier to engage the L-shaped pawl 16 with the engagement protrusion 17. be.

The lid 2 has a plurality of (three in the illustrated example) recessed portions 18 (18A to 18C) as measuring means in a region (center) inside the fitting portion 13, and the recessed portions 18 serve as measuring means. At this time, the lid 2 is used in a state where it can be measured with the lower surface of the periphery facing upward (the state shown in FIG. 1(B), which is upside down from the state shown in FIG. 1(A)).

Specifically, as shown in FIGS. 1(B) and 1(C), the space inside the fitting part 13 of the lid 2 is divided by partition walls 19 extending radially in three directions from the center of the fitting part 13 (inner lid 8). The space is divided into three parts, and a recessed part 18 is provided at a position closer to the center of the lid 2 in each of the thus divided spaces. The three recesses 18 have different sizes, and are provided in the space labeled "2.5" in FIG. In this case, the recessed part 18A (also referred to as the recessed part 18A) is the smallest, and the recessed part 18 (hereinafter also referred to as the recessed part 18B) provided in the space marked with "5" is the next smallest and the space marked with "10". The recessed portion 18 (hereinafter also referred to as recessed portion 18C) provided in is the largest.

Specifically, as shown in FIG. 1C, each of the three recesses 18 has a substantially fan shape in bottom view (plan view) with a central angle of 120 degrees, and the recesses 18A and 18B have a fan shape. have substantially the same radius, and the recessed part 18B is made deeper than the recessed part 18A (the recessed part 18A is approximately 80% as deep as the recessed part 18B) (see FIG. 1(A)). Further, the recessed portion 18B and the recessed portion 18C have the same depth, and the fan-shaped radius of the recessed portion 18C is made longer.

That is, in the lid 2 of this example, three types of measurements, 2.5 ml, 5 ml, and 10 ml, can be performed using the recessed portions 18A to 18C.

In addition, as shown in FIG. 1(A), the top surfaces (bottom surfaces in the measurable state shown in FIG. 1(B)) of the recessed portions 18B and 18C are made flat and at the same height. The lid 2 shown in (B) in a state ready for measurement can be placed with good stability on a horizontal surface such as a table.

Furthermore, as shown in FIG. 1C, each corner of the recesses 18A to 18C is rounded to improve cleaning performance.

In the lid 2 having the above configuration, the fitting part 13 with the packing attached to the annular groove 15 is inserted into the mouth part 1a of the main body 1, and in this state, the lid 2 is rotated around the axis and the L-shaped claw 16 By engaging with the engagement protrusion 17, the lid 2 can be attached to the mouth portion 1a of the main body 1, and the material (to be mixed) in the main body 1 will not leak in this state (locked state). Therefore, in this locked state, the shaker S can be shaken with one hand while holding the handle 4.

Then, as shown in FIGS. 1(A) and (C), a suitable position of the lid 2 (in this example, a recess is formed in the space surrounded by the fitting part 13 and the partition wall 19 in the lid 2, and where the recessed part 18A is located). A ventilation section 40 that can be opened and closed is provided in an area (avoiding the entry section 18A).

As shown in FIG. 2(A), the ventilation section 40 connects the internal space of the shaker S (the lower space of the lid 2 in FIG. 2(A)) to the external space (the upper space of the lid 2 in FIG. 2(A)). It is equipped with a ventilation hole 20, which is a through hole passing through the lid 2 in the vertical direction, and a valve V that closes the ventilation hole 20. As shown in FIG. 2(B), the valve V is connected to the inside of the shaker S. The ventilation hole 20 is configured to be opened when pressed toward the bottom.

Specifically, as shown in FIG. 2(C), the valve V has a substantially cylindrical head V1, an upper flange V2, a body V3, and a lower flange V4 in this order from the upper side, The centers of each part V1 to V4 are aligned. Further, as shown in FIG. 3, the vent hole 20 has an annular frame 41 on its upper surface side (outer surface side) periphery that is more raised than other parts, and vent grooves 41a are formed on four sides of this frame 41. On the other hand, the peripheral edge on the lower surface side (inner surface side) is formed to be flush with other parts.

That is, when the valve V is attached to the vent hole 20 as shown in FIG. 2(A), the lower surface of the upper flange V2 of the valve V comes into contact with the upper surface of the frame 41. Furthermore, although the outer circumferential surface of the body portion V3 of the valve V may partially come into close contact with the inner circumferential surface of the vent hole 20, the whole does not come into close contact with the inner circumferential surface of the vent hole 20. On the other hand, the upper surface of the lower flange V4 of the valve V comes into close contact with the periphery of the lower surface of the vent hole 20 and closes the vent hole 20. That is, the portion of the lower periphery of the vent hole 20 where the upper surface of the lower flange V4 is in close contact functions as a valve seat.

Then, when the valve V is pressed toward the inside (lower side) of the shaker S as shown in FIG. Separate. At this time, the air inside the shaker S flows between the upper surface of the lower flange V4 and the lower peripheral edge (valve seat) of the ventilation hole 20, between the outer peripheral surface of the body V3 and the inner peripheral surface of the ventilation hole 20, and between the outer peripheral surface of the body V3 and the inner peripheral surface of the ventilation hole 20. External air can flow out to the outside through the vent groove 41, and external air can also flow into the shaker S by following the opposite route, that is, the vent hole 20 is in an open state. Note that when the pressure is stopped, the valve V elastically returns to the state shown in FIG. 2(A).

Here, in the non-pressed state (valve closed state) shown in FIG. In the pressed state (valve open state) shown in 2(B), it is necessary for the lower flange V4 to be elastically deformed so as to separate from the valve seat, and in order to ensure ease of this elastic deformation, in this example, The head V1 has a smaller diameter than the body V3.

In addition, in order to ensure that the lower flange V4 is in close contact with the valve seat, the thickness (height) h3 (see Fig. 2 (C)) of the body portion V3 is equal to the thickness of the valve mounting portion, which is the sum of the vent hole 20 and the frame 41. t (see FIG. 3), and the thickness h4 of the lower flange V4 is preferably equal to or greater than the thickness h2 of the upper flange V2.

Specifically, the outer diameters d1 to d4 and thicknesses (heights) h1 to h4 (see FIG. 2(C)) of each part V1 to V4 of the valve V are d1 = 7.0 to 7.5 mm, d2 = 10 .8~12.0mm, d3=8.1~8.4mm, d4=11.5~12.0mm, h1=1.2~1.3mm, h2=0.6~1.7mm, h3=1 .9 to 2.0 mm, h4 = 1.6 to 1.7 mm, the thickness t of the valve mounting part including the vent hole 20 and frame 41 is 2.2 to 2.4 mm, and the depth of the vent groove 41a is 0. It is conceivable that the width of the vent groove 41a is 1.2 to 1.5 mm.

Here, when the mouth part 1a is closed with the lid 2 with high-temperature material put into the main body 1, and the shaker S is shaken in this closed state, the air inside the shaker S comes into contact with the high-temperature material and heats up. When the internal pressure of the shaker S increases accordingly, there is a possibility that the contents (to be mixed) may be spewed out when the lid 2 is removed. Furthermore, if the internal pressure of the main body 1 decreases due to a decrease in the temperature of the air inside the shaker S, the lid 2 may become stuck to the main body 1, making it difficult to remove the lid 2.

However, in the shaker S of this example in which the ventilation portion 40 as described above is provided, as shown in FIG. Since it is opened and air can circulate between the inside and outside of the shaker S, it is possible to alleviate or suppress the increase or decrease in the internal pressure of the shaker S, thereby preventing the above-mentioned phenomenon of contents gushing out and the difficulty of removing the lid 2. It is possible to prevent such phenomena from occurring.

In the shaker S of the present example described above, mixing objects can be quickly performed by putting the object to be mixed into the shaker S and shaking it in the closed state. During this shaking motion, if the handle 4 is in the locked state, it is possible to shake with one hand, but it may be difficult to shake with one hand due to muscle strength, or if you take your hand off the lid 2. If you feel uneasy about shaking, for example, hold the protruding part 5 that protrudes from the bottom of the main body 1 to the sides, and the outer edge part of the lid 2 that protrudes to the sides from the top of the main body 1, and shake them together. You may shake while pressing, and in either case, it is difficult for the heat of the mixture to be transferred into the shaker S to be transferred to the hands. Moreover, if the L-shaped pawl 16 is not engaged with the engagement protrusion 17 after the mixing operation is completed, the lid 2 can be easily closed with one hand by pushing up the outer edge of the lid 2 while holding the handle 4. You can open 2.

In addition, in the shaker S, the measuring scale 3 of the main body 1 is used to measure miso soup, for example, and the recessed part 18 of the lid 2 is used to measure thickening agent, for example. By weighing each separate material, it is possible to mix multiple materials in appropriate amounts. Since such mixing can be performed using only the main body 1 and the lid 2, it is possible to reduce the number of instruments used and to greatly reduce the labor required for tasks such as cleaning the instruments after use.

If the ventilation part 40 (ventilation hole 20 and valve V) is provided on the main body 1 side, there is a risk that material may leak from the open ventilation hole 20 depending on the position where it is provided and the amount of material in the internal space. In the shaker S of this example in which the ventilation portion 40 is provided in the lid 2, such leakage can be prevented.

Moreover, since the measuring means (recessed part 18) is provided in the lid 2, it is easy to arrange this measuring means so as to face the internal space of the shaker S in the closed state. 18) faces the inner space of the main body 1, even if some of the material measured by the measuring means remains on the surface of the measuring means due to its high viscosity, it will not be shaken. This ensures better and faster mixing as the other materials come into contact with each other during operation.

Further, in the shaker S, since the handle 4 is provided on the main body 1, the main body 1 can be used as a cup (for drinking) by opening (removing) the lid 2.

It should be noted that the present invention is not limited to the embodiments described above, and it goes without saying that various modifications can be made without departing from the gist of the present invention. For example, the following modifications can be given.

In the handle 4 shown in FIGS. 1(A) and 1(B), the meat on both the left and right sides is removed to reduce weight and prevent shrinkage and deformation during molding, but the location where the meat is removed can be changed as appropriate. , for example, you may want to avoid skipping meat. Moreover, the handle 4 can take various forms, and the number thereof is not limited to one, but may be two or more.

In the examples shown in FIGS. 2(A) to (C) and FIG. 3, the frame 41 Although a total of four vent grooves 41a are provided, the number of vent grooves 41a is not limited to this. Further, the structure for allowing the air to circulate is not limited to the frame 41 with the vent groove 41a, but may be, for example, a plurality of protrusions.

Further, the structure for allowing the air to circulate may be provided on the upper flange V2 side instead of on the ventilation hole 20 side. For example, the upper flange V2 may be configured to be discontinuous in its circumferential direction. It is. When the above-mentioned structure is provided on the upper flange V2 side in this way, the periphery of the upper surface side (outer surface side) of the ventilation hole 20 can also be formed in a plane flush with other parts.

When the valve V shown in FIG. 2(C) is pressed as shown in FIG. 2(B), high-temperature steam and air can flow out from between the upper flange V2 and the top surface of the vent hole 20 due to this pressing operation. Because there is a risk of burns if you come into contact with this steam, etc., the head V1, which receives the pressing force, should be pressed with a stick of an appropriate thickness (for example, chopsticks, the handle of a spoon or fork, etc.). Assuming that, the thickness (height) h1 is configured to be relatively small. However, the present invention is not limited to this, and the thickness (height) h1 of the head V1 may be appropriately increased so as not to cause burns even if the head V1 is pressed with a finger, for example.

In the examples of FIGS. 1A and 1C, only one ventilation part 40 is provided in the lid 2, but a plurality of ventilation parts 40 may be provided, and in this case, the head of the valve V in each ventilation part 40 It may be configured such that when the V1 are appropriately connected and the connected portion is pressed, the ventilation holes 20 of all the ventilation portions 40 are opened at once.

As shown in FIGS. 4A and 4B, a protruding wall 42 surrounding the ventilation portion 40 may be provided on the upper surface (outer surface) of the lid 2. In this case, it can be expected that the protruding wall 42 will suppress the spread of the contents spewed out from the ventilation section 40 to the outside.

Further, in the example of FIG. 1(A), the ventilation part 40 is provided in the lid 2, but the invention is not limited to this. For example, the ventilation part 40 may be provided in the main body 1, and the material leaks from the open ventilation hole 20. It is preferable to provide the ventilation section 40 at the upper part (upper side surface) of the main body 1 from the viewpoint of making it difficult for the user to use the device. It is preferable to provide it at a certain position.

In the example of FIG. 2(A), the lower flange V4 is configured to completely protrude to the inner surface (lower surface) side of the vent hole 20 and close the vent hole 20, but the configuration is not limited to this. 5, a tapered surface 20a is provided on the lower (inside) side of the inner peripheral surface of the vent hole 20, and the upper surface of the lower flange V4 has a tapered surface that can come into close contact with the tapered surface 20a. When V closes the vent hole 20, the lower flange V4 comes into close contact with the vent hole 20 (tapered surface 20a), and part or all of the lower flange V4 protrudes to the inner surface (lower surface) side of the vent hole 20. It may be configured so that there is no such thing. In this case, it becomes easy to reduce the size of the valve V.

In the examples of FIGS. 1A to 1C, three recesses 18 are provided in the lid 2 as measuring means, but the invention is not limited to this, and the number of recesses 18 may be two or less or four or more. Often, the size of the recessed portion 18 can also be changed as appropriate. Furthermore, when a plurality of recesses 18 are provided, they do not necessarily have to be arranged in the circumferential direction around the center of the lid 2, but may be arranged in a single row or other matrix, or in a staggered pattern, for example.

In the shaker S shown in FIGS. 1A to 1E, the lid 2 is removably attached to the mouth portion 1a of the main body 1 by fitting with the fitting portion 13 and engaging the L-shaped pawl 16 with the engagement protrusion 17. However, the attachment/detachment structure is not limited to this. For example, the lid 2 may be detachably attached to the main body 1 by screw connection, or a stopper of an appropriate structure that engages with the main body 1 in the closed state may be attached to the lid 2. The lid 2 may be removably attached to the main body 1 by providing the lid 2 with the main body 1.

Note that it goes without saying that the modifications mentioned in this specification may be combined as appropriate.
