Description

Applicable to Article 30, Paragraph 2 of the Patent Law. Product description materials for the in-car drink holder were distributed to Autobacs Seven Co., Ltd. on June 11, 2021. Product description materials for the in-car drink holder were distributed to Yellow Hat Co., Ltd. on July 27, 2021. Product description materials for the in-car drink holder were distributed to Toyota Mobility Parts Co., Ltd. on July 28, 2021.

This disclosure relates to an in-vehicle drink holder.

A well-known example is the in-car drink holder that is installed in a vehicle.
An in-car drink holder is configured to support a beverage container. For example, an in-car drink holder is configured to be attached to the air conditioning vent of a vehicle (Patent Document 1).

By using the vehicle's built-in drink holder, passengers are freed from the burden of constantly holding onto their beverage containers.
Examples of beverage containers include PET bottles, water bottles, paper cups, and plastic cups. Of these, paper cups have a bottom wall that extends downward from the periphery of the bottom surface, creating a space in the area below the bottom surface and inside the bottom wall. In a paper cup, the beverage is contained in the area above the bottom surface, and no beverage is placed in the space formed by the bottom surface and bottom wall. In other words, a paper cup is configured so that the beverage is placed at a position higher than the lowest part of the paper cup itself (the lower end of the bottom wall).

Furthermore, in-car drink holders are designed to maintain the temperature of beverages by directing cool or warm air from the air conditioner onto the beverage container.

Japanese Patent Application Publication No. 10-217825

However, vibrations during vehicle operation may cause beverage containers to move or change position (tilt) within the car's drink holder. If the beverage container tilts significantly, it may fall out of the drink holder. In particular, as mentioned above, paper cups are prone to tilting because the beverage is positioned higher than the bottom of the cup, resulting in a higher center of gravity.

Furthermore, the cool or warm air from an air conditioner may alter the temperature of a beverage to an unsuitable level, depending on its temperature. For example, with cold beverages containing ice, the relatively high temperature of the air conditioner's cool air could raise the beverage's temperature. Conversely, with hot beverages such as hot coffee, the relatively low temperature of the air conditioner's warm air could lower the beverage's temperature.

Therefore, in this disclosure, it is desirable to provide an in-vehicle drink holder that suppresses the detachment of beverage containers due to vehicle vibrations. Furthermore, in this disclosure, it is desirable to provide an in-vehicle drink holder that maintains the temperature of beverages (cooling or warming) while minimizing the effects of air conditioning.

An in-vehicle drink holder according to one aspect of this disclosure comprises a holder body and a container storage section. The in-vehicle drink holder is configured to support a beverage container.
The holder body is configured to be fixed to the vehicle. The container housing section is formed in the shape of a bottomed cylinder with an open first end and a closed second end. The container housing section is configured to be supported by the holder body.

The container housing comprises a side wall and a bottom. The side wall is formed in a cylindrical shape, extending axially from the first end to the second end. The side wall is configured to provide a space for arranging at least a portion of the beverage container. The bottom is formed to close the second end of the side wall.

The container housing section is provided with an inner projection. The inner projection protrudes from the inner surface of the bottom toward the first end. The inner projection is configured to form a gap space between it and the inner surface of the side wall.

Here, one example of a beverage container is one in which the bottom wall extends from the periphery of the bottom surface. This beverage container has a beverage placement area above the bottom surface for holding the beverage.

Furthermore, when a beverage container having a bottom wall extending from the periphery of its bottom surface is placed in the in-vehicle drink holder of this disclosure, the bottom wall is positioned in the gap space, and the beverage container is supported in such a state that the inner protrusion is covered by the bottom surface and bottom wall of the beverage container. As a result, the range of movement of the bottom wall of the beverage container is restricted by the inner protrusion, thereby suppressing the movement of the beverage container due to vehicle vibrations.

Therefore, this in-car drink holder can prevent beverage containers from falling out due to vehicle vibrations.
Next, the inner protrusion may have a cross-sectional shape perpendicular to the axial direction that is circular, annular, polygonal, or cross-shaped. The inner protrusion is not limited to a specific shape; it can take any shape that restricts the range of movement of the bottom wall of the beverage container.

Next, the inner protrusion may comprise a plurality of smaller protrusions. These smaller protrusions may be distributed concentrically around the central position of the bottom. The inner protrusion is not limited to a single component; it can comprise multiple components as long as its shape restricts the range of movement of the bottom wall of the beverage container.

Next, the first height dimension of the inner protrusion may be 5% or more of the second height dimension of the container housing. Alternatively, the first height dimension may be 50% or less of the second height dimension. The first height dimension is the height dimension of the inner protrusion parallel to the axial direction. The second height dimension is the height dimension of the internal space of the container housing parallel to the axial direction.

By ensuring the first height dimension is 5% or more of the second height dimension, the bottom wall of the beverage container can be prevented from overhanging the inner protrusion. By ensuring the first height dimension is 50% or less of the second height dimension, sufficient space for the beverage container can be secured within the container storage area, thus stably supporting the beverage container. Therefore, this in-car drink holder can prevent the beverage container from falling out of the container storage area.

The first height dimension may be, for example, 5 mm or more. The first height dimension may be, for example, 15 mm or less.
Next, the bottom portion has a circular cross-sectional shape perpendicular to the axial direction, and a predetermined virtual circle centered at the central position of the bottom portion may be defined as the first virtual circle. The inner protrusion may be configured such that the entire inner protrusion is housed inside the first virtual circle, and at least a portion of the inner protrusion is inscribed in the first virtual circle. The first virtual circle is a virtual circle whose diameter is 70% or more of the diameter of the bottom portion, and whose diameter is 95% or less of the diameter of the bottom portion.

With the inner protrusion configured in this way, it is formed within a predetermined range relative to the diameter of the base, thereby limiting the range in which the beverage container can move within the base to an appropriate range.

The diameter of the first virtual circle may be, for example, 30 mm or more. The diameter of the first virtual circle may be, for example, 55 mm or less.
Next, the side wall may have an annular cross-sectional shape perpendicular to the axial direction. The side wall may have a tapered shape in which the outer diameter of the first end is larger than the outer diameter of the second end. The bottom may have a circular cross-sectional shape perpendicular to the axial direction.

The internal shape of this container holder conforms to the tapered external shape of a beverage container, where the diameter increases from the bottom to the top. Therefore, this in-car drink holder can suppress the movement of beverage containers caused by vehicle vibrations when supporting such containers.

The outer diameter of the first end may be, for example, 70 mm or more and 100 mm or less. The outer diameter of the second end may be 50 mm or more and 80 mm or less. The height dimension parallel to the axial direction in the container housing may be 70 mm or more and 150 mm or less.

The container housing may have an insulating structure on its side walls and bottom. Such a container housing can suppress the transfer of temperature (heat) between the beverage container and the outside air, thereby suppressing temperature changes in the beverage caused by air conditioning.

Embodiments to which this disclosure applies will be described below with reference to the drawings.
Furthermore, this disclosure is not limited in any way to the embodiments described below, and it goes without saying that it can take various forms as long as they fall within the technical scope of this disclosure.

[1. First Embodiment]
[1-1. Overall Structure]
The in-vehicle drink holder 1 shown in Figure 1 of this embodiment is installed inside the passenger compartment of a vehicle such as an automobile. The in-vehicle drink holder 1 is configured to be attachable to the air conditioning vent inside the vehicle.

As shown in Figures 1 and 2, the in-vehicle drink holder 1 comprises a holder body 11 and a container storage section 13.

As shown in Figures 2 and 3, the container housing section 13 is formed in a closed-bottom cylindrical shape with an open first end 13a and a closed second end 13b. The first end 13a is the upper end of the container housing section 13. The second end 13b is the lower end of the container housing section 13. As shown in Figure 1, the container housing section 13 is configured to be supported by the holder body 11.

As shown in Figure 4, the container housing section 13 is configured to support the beverage container 41. The container housing section 13 is configured to house a portion of the beverage container 41 within its interior.

Details of the container housing section 13 will be described later.
Such an in-car drink holder 1 can be attached to the air conditioning vent of a vehicle to support a beverage container 41.

[1-2. Container Storage Section]
As shown in Figure 3, the container housing section 13 comprises a side wall 31 and a bottom section 33.
The side wall 31 is formed in a cylindrical shape that extends in the axial direction from the first end 13a to the second end 13b. The side wall 31 is configured to provide a space for arranging at least a portion of the beverage container 41. The side wall 31 has an annular cross-sectional shape perpendicular to the axial direction. The side wall 31 is formed in a tapered shape where the outer diameter L1 of the first end 13a is larger than the outer diameter L2 of the second end 13b (L1 > L2).

In this embodiment, the container housing section 13 has an outer diameter L1 of 84.6 mm and an outer diameter L2 of 72.3 mm.
The bottom portion 33 is formed to close the second end 13b of the side wall 31. The bottom portion 33 has a circular cross-sectional shape perpendicular to the axial direction.

The container housing section 13 is equipped with an inner protrusion 35.
The inner projection 35 protrudes from the inner surface of the bottom portion 33 toward the first end 13a. The inner projection 35 is configured to form a gap space 37 between it and the inner surface of the side wall 31. The inner projection 35 has a circular cross-sectional shape perpendicular to the axial direction. The inner projection 35 is formed in a circular shape with its center located at the center of the inner bottom surface of the second end 13b.

The container housing section 13 has an inner diameter L3 at the inner bottom surface of the second end 13b that is smaller than the outer diameter L2 by the wall thickness of the side wall 31. The inner protrusion 35 has a diameter L4 perpendicular to the axial direction that is smaller than the inner diameter L3.

In this embodiment, the height dimension H1 from the upper end to the lower end of the outer part of the container housing section 13 is 89.6 mm. The height dimension H2 from the upper end to the lower end (inner bottom) of the inner part of the container housing section 13 is 83.6 mm. Within the container housing section 13, the inner diameter dimension L3 is 64.8 mm, and the diameter dimension L4 is 46.6 mm. The height dimension H3 of the inner protrusion 35 is 7.6 mm.

The container housing section 13 is made of stainless steel (SUS304). The side walls 31 and bottom 33 of the container housing section 13 are both insulated. Specifically, the wall cavity regions 13c of the side walls 31 and bottom 33 are configured to be in a vacuum state. These wall cavity regions 13c correspond to the contents of the side walls 31 and bottom 33 themselves. The wall cavity regions 13c are distinct from the space (area) where the beverage is placed.

[1-3. Container housing section in a state where a beverage container is supported]
Here, we will explain how the container storage section 13 supports three different types of beverage containers of varying sizes.

As shown in Figure 4, three types of beverage containers are used: a small-sized container 41, a medium-sized container 43, and a large-sized container 45. The small-sized container 41 comprises a small container body 41a and a small lid 41b. The medium-sized container 43 comprises a medium-sized container body 43a and a medium-sized lid 43b. The large-sized container 45 comprises a large container body 45a and a large lid 45b.

The small container body 41a, the medium container body 43a, and the large container body 45a are each made of what is commonly known as a paper cup. The small lid 41b, the medium lid 43b, and the large lid 45b are each made of plastic material.

First, as shown in Figure 5, the small-sized container 41 is configured so that the small container body 41a and the small lid 41b can be assembled together. The small lid 41b is configured to cover the open end of the small container body 41a.

The small container body 41a comprises a bottom portion 41c and a bottom wall portion 41d. The bottom portion 41c constitutes the bottom surface of the beverage placement area within the small container body 41a. The bottom wall portion 41d extends downward from the periphery of the bottom portion 41c. The small container body 41a is configured such that a space is formed in the area below the bottom portion 41c and inside the bottom wall portion 41d.

The height dimension TH1 of the small container body 41a is 96.0 mm. The inner diameter dimension CL1 of the lowest part of the bottom wall 41d of the small container body 41a is 52.5 mm. The height dimension CH1 of the bottom wall 41d of the small container body 41a is 9.0 mm.

When the lower portion of the small-sized container 41 is placed inside the container housing section 13, the inner protrusion 35 is covered by the bottom portion 41c and the bottom wall portion 41d. At this time, the bottom wall portion 41d is positioned in the gap space 37. Furthermore, a gap exists between the inner protrusion 35 and the bottom portion 41c, and the container housing section 13 supports the small-sized container 41 with its inner bottom portion in contact with the bottom wall portion 41d.

As a result, the range of movement of the bottom wall portion 41d of the small-sized container 41 is restricted by the inward protrusion 35, thereby suppressing the movement of the small-sized container 41 due to vehicle vibrations. In other words, the container housing portion 13 can prevent the small-sized container 41 from falling out of the container housing portion 13 due to vehicle vibrations.

Next, as shown in Figure 6, the medium-sized container 43 is configured so that the container body 43a and the inner lid 43b can be assembled together. The inner lid 43b is configured to cover the open end of the container body 43a.

The inner container body 43a comprises a bottom portion 43c and a bottom wall portion 43d. The bottom portion 43c constitutes the bottom surface of the beverage placement area within the inner container body 43a. The bottom wall portion 43d extends downward from the periphery of the bottom portion 43c. The inner container body 43a is configured such that a space is formed in the area below the bottom portion 43c and inside the bottom wall portion 43d.

The height dimension TH2 of the inner container body 43a is 107.7 mm. The inner diameter dimension CL2 of the lowest part of the bottom wall portion 43d of the inner container body 43a is 59.5 mm. The height dimension CH2 of the bottom wall portion 43d of the inner container body 43a is 9.7 mm.

When the lower portion of the medium-sized container 43 is placed inside the container housing section 13, the inner protrusion 35 is covered by the bottom portion 43c and the bottom wall portion 43d. At this time, the bottom wall portion 43d is positioned in the gap space 37. Furthermore, a gap exists between the inner protrusion 35 and the bottom portion 43c, and the container housing section 13 supports the medium-sized container 43 with its inner bottom portion in contact with the bottom wall portion 43d.

In this case, the gap between the bottom wall portion 43d and the inner surface of the side wall 31 is smaller than the gap between the bottom wall portion 43d and the inner protrusion 35. In this case, the range of movement of the bottom wall portion 43d of the medium-sized container 43 is limited by the inner surface of the side wall 31, thus suppressing the movement of the medium-sized container 43 due to vehicle vibrations. In other words, the container housing portion 13 can prevent the medium-sized container 43 from falling out of the container housing portion 13 due to vehicle vibrations.

Next, as shown in Figure 7, the large-sized container 45 is configured so that the large container body 45a and the large lid 45b can be assembled together. The large lid 45b is configured to cover the open end of the large container body 45a.

The large container body 45a comprises a bottom portion 45c and a bottom wall portion 45d. The bottom portion 45c constitutes the bottom surface of the beverage placement area within the large container body 45a for arranging beverages. The bottom wall portion 45d extends downward from the periphery of the bottom portion 45c. The large container body 45a is configured such that a space is formed in the area below the bottom portion 45c and inside the bottom wall portion 45d.

The height dimension TH3 of the large container body 45a is 126.0 mm. The inner diameter dimension CL3 of the lowest part of the bottom wall 45d of the large container body 45a is 61.0 mm. The height dimension CH3 of the bottom wall 45d of the large container body 45a is 6.0 mm.

When the lower portion of the large-sized container 45 is placed inside the container housing section 13, the inner protrusion 35 is covered by the bottom 45c and the bottom wall 45d. At this time, the bottom wall 45d is positioned in the gap space 37. Also, at this time, the inner protrusion 35 and the bottom 43c are in contact. The container housing section 13 supports the large-sized container 45 with the inner protrusion 35 in contact with the bottom 45c.

In this case, the size of the area where the inner protrusion 35 and the bottom 45c abut (hereinafter also referred to as the first contact area) is larger than the size of the area where the lower end of the bottom wall 45d abuts against the inner surface of the bottom 33 (hereinafter also referred to as the second contact area). Therefore, the frictional force generated at the contact point between the inner protrusion 35 and the bottom 45c is greater than the frictional force generated at the contact point between the lower end of the bottom wall 45d and the inner surface of the bottom 33.

As a result, the range of movement of the bottom 45c of the large container 45 is limited by the frictional force generated between the inner protrusion 35 and the bottom 45c, thereby suppressing the movement of the large container 45 due to vehicle vibrations. In other words, the container housing section 13 can prevent the large container 45 from falling out of the container housing section 13 due to vehicle vibrations.

[1-4. Effects]
As described above, the in-car drink holder 1 is equipped with a container storage section 13 having an inner protrusion 35, which prevents beverage containers (small-sized containers 41, large-sized containers 45) from falling out of the in-car drink holder 1 due to vehicle vibrations.

The inner shape of the container storage section 13 conforms to the outer shape of the tapered beverage containers (small-sized container 41, medium-sized container 43, and large-sized container 45). Therefore, this in-vehicle drink holder 1 can suppress the movement of beverage containers due to vehicle vibrations when supporting beverage containers of this shape.
