Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a heat-retaining container such as a thermos flask that is made of stainless steel and has a vacuum-insulated double wall structure.

(Prior Art) Conventionally, there have been heat-retaining containers with a heat-insulating double-walled structure, such as those used exclusively for keeping liquids warm (thermos flasks) and those used exclusively for keeping lunch boxes warm (lunch box warm-up containers).

However, in liquid heat-insulating containers (thermos), the opening for replenishing the liquid is generally narrow, so it is not possible to put large-diameter ice (larger than the diameter of the opening) through the opening, and the inside cannot be filled with ice. In addition to the problem of being difficult to clean, their use was limited to keeping liquids warm (for example, they could only store ice or other items such as canned youth or canned beer to keep them warm). I couldn't do it).

Furthermore, although the lunchbox heat-insulating container has a wide upper opening, the structure is not suitable for storing liquid.

(Purpose of the invention) In view of the above-mentioned problems of the conventional thermal insulation container, the present invention is capable of storing and keeping warm not only liquids but also ice alone or canned drinks.
The object of the present invention is to provide a heat-retaining container that is easy to use.

(Means for Achieving the Object) The insulating container of the present invention has an insulating double wall structure with a vacuum between the outer cylinder and the inner cylinder made of stainless steel plates, and the length of the body is the outer diameter of the outer cylinder. The container body is configured such that the upper end opening has a wide opening that is approximately the same diameter as the inner diameter of the inner cylinder, and the outer cylinder has an outer diameter that is approximately the same as the outer diameter of the outer cylinder at the upper end of the outer cylinder of the container body. A shoulder member having a diameter is removably screwed together, an opening for liquid pouring is formed in the shoulder member, a stopper is provided in the opening, and the shoulder member has a diameter approximately the same as the outer diameter of the outer cylinder. A cover body which also serves as a tip and has an outer diameter of the same diameter as the outer diameter is removably screwed together, and in the screwed state of the cover body, the outer surface of the cover body, the outer surface of the shoulder member, and the outer surface of the outer cylinder are respectively It is characterized by being continuous without any steps.

(Function) The heat insulating container of the present invention has a wide opening at the upper end of the container body with a diameter approximately the same as the inner diameter of the container, and a shoulder member is detachably attached to the edge of the upper end opening. When the member is removed from the container body, the wide upper opening becomes open, and it becomes possible to put large diameter ice or the like through the upper opening. Further, by unscrewing the cover body and opening the stopper while the shoulder member is attached to the container body, the liquid contained inside can be poured out from the liquid pouring opening of the shoulder member.

In addition, when the cover body is screwed together, the outer surface of the cover body, the outer surface of the shoulder member, and the outer surface of the outer cylinder are continuous with each other without any step, making it easy to carry and saving space when stored. I won't take it anymore.

(Embodiments) Several embodiments of the present invention will be described with reference to FIGS. 1 to 7. FIGS. 1 and 2 show the first embodiment of the present invention, and FIGS. 3 to 5 1 shows a heat-insulating container according to the second embodiment, and FIGS. 6 and 7 show a heat-insulating container according to the third embodiment.

The heat-insulating containers of the first embodiment shown in FIGS. 1 and 2 are mainly designed for indoor use, and each container has a vacuum-insulated double wall structure consisting of an outer cylinder 11 and an inner diameter 12 made of stainless steel plates. At the top of body 1,
A shoulder member 2 having a liquid pouring opening 21 that can be opened and closed by a stopper 3 and having an outer diameter approximately the same as the outer diameter of the outer cylinder 11 is detachably attached to the shoulder member 2. A cover body 4 having an outer diameter approximately the same as the outer diameter of the outer cylinder 11 and also serving as a tip is provided on the upper part. That is, in the case of the heat-insulating container of this embodiment, the outer surface of the cover body 4, the outer surface of the shoulder member 2, and the outer surface of the outer cylinder 11 are made to be continuous with each other without any difference in level.

The container body 1 has a wide mouth whose body length (symbol A) is larger than the body diameter (symbol B) and whose upper end opening 13 has the same diameter as the inside diameter of the container body 1.

A male thread 14 is formed on the upper outer periphery of the container body 1 (that is, on the outer periphery of the upper end of the outer tube 11) to which the shoulder member 2 is removably screwed. Further, a bottom plate 9 is provided at the bottom of the container body 1.

The shoulder member 2 is formed by integrating an upper member 25 and a lower member 26 by ultrasonic bonding (ultrasonic bonding portion 27). The inner surface of the outer circumferential wall 23 of the shoulder member 2 (the outer circumferential wall of the upper member 25) has a container body 1
A female thread 24 is formed which can be screwed into the male thread 14 of the shoulder member 2.
It is designed to be able to be removably attached to a by screws.

An opening 21 is formed in the center of the shoulder member 2 for pouring out the liquid inside while the shoulder member 2 is attached to the container body 1. This liquid pouring opening 21
In this first embodiment, the diameter is relatively small and is mainly used only when pouring out the internal liquid to the outside.

The stopper 3 that opens and closes the liquid pouring opening 21 is
In this first embodiment, a cylindrical member 31 having a liquid passage 32 inside is used.
is mounted on a shaft (shaft 35) above the liquid pouring opening 21 so as to be rotatable in an arc within a range from a horizontal position to a vertical position. When the cylindrical member 31 is in a horizontal position as shown by the solid line in FIG. When the liquid outlet 21 and the liquid passage 32 of the stopper 3 are in the vertical position as shown in the figure, the liquid in the container 1 is transferred to the liquid outlet 21 and the liquid passage 32 of the stopper 3.
1 and liquid passage 32 to the outside. The stopper 3 is opened and closed by pinching the operating portion 34 formed by extending a portion of the cylindrical member 31 and rotating it in an arc.

A male thread 28 is formed on the upper part of the shoulder member 2 for screwing in and removing the cover body 4 which also serves as a tip.
A female screw 41 is screwed together.

In the heat-insulating container of the first embodiment, when the shoulder member 2 is screwed onto the container body 1 and removed, the opening 13 of the container body 1 is opened. At this time, since the stopper 3 is attached to the shoulder member 2, the stopper 3 is also removed from the container body 1 when the shoulder member 2 is removed.
In addition, when removing the shoulder member 2, the cover body 4
It is also possible to carry out the operation while the shoulder member 2 is attached to the shoulder member 2. When the shoulder member 2 is removed from the container body 1, the opening 13 of the container body 1 is opened, but since the opening 13 has a wide mouth, it is difficult to clean the inside.
The work of storing liquid, ice, etc. can be easily performed, and even if the ice pieces have a relatively large diameter (smaller than the opening 13), they can be stored as they are in the container body 1. Incidentally, when this heat insulating container is used as an ice container for making whiskey with water, etc., only ice pieces are stored in the container body 1. After storing a liquid or the like in the container body 1, by screwing the shoulder member 2 onto the upper part of the container body 1, the contents inside the container body 1 are kept warm. When taking out the liquid stored in the container body 1, remove the cover body 4, open the stopper 3, and tilt the entire heat insulating container. It can be poured out through the passage 32 to the outside. At this time, the shoulder member 2 remains attached to the container body 1, and the stopper 3 only needs to be rotated in an arc without removing it from the shoulder member 2. , plug body 3, etc.).

Furthermore, in the heat-insulating container of the present embodiment, the outer surface of the cover body 4, the outer surface of the shoulder member 2, and the outer surface of the outer cylinder 11 are configured to be continuous with each other without a step (that is, a structure without a protrusion). For,
Not only is it convenient to carry, but it also takes up less storage space.

In the heat-insulating container of the second embodiment shown in FIGS. 3 to 5, a handle unit 61 formed by integrally molding a ring body 62 and a handle portion 63 can be attached to the outer surface of the container body 1 in a freely replaceable manner. That's what I do. That is, the inner diameter of the ring body 62 of this handle unit 61 is approximately the same diameter as the outer diameter of the container body 1, and a cut groove 64 that reaches the inner surface of the ring body 62 is formed in the upper portion of the handle portion 63. has been done. This handle unit 61 is constructed by fitting the inner diameter part of the ring body 52 from below the container body 1 to a suitable position near the upper end of the outer surface of the container body 1, and then tightening the base part of the handle part 63 with a screw 65 and a nut 66. It is tightened and fixed to the container body 1. On the inner surface of the ring body 62, there are two friction rubbers 67, 67 for preventing the ring body 62 (handle unit) from rotating with respect to the container body 1.
There are places set up. This handle unit 61 is
When the screw 65 is loosened, the container body 1 can be removed by shifting it downward along the outer surface of the container body 1. Therefore, during storage, the handle unit 61 can be removed and the storage space can be reduced. Note that this handle unit 61 can be replaced with a hanging cord attachment ring (FIG. 6) which will be described next.

The third embodiment shown in FIGS. 6 and 7 shows a hanging string attachment ring 71 used in place of the handle unit 61 in the heat-insulating container shown in FIG. This hanging string attachment ring 71 is composed of two divided ring pieces (1/2 circumference each) 72, 72. It is attached to the outer circumferential surface of the container body 1 by tightening the ends of the two split ring pieces 72, 72 with screws 73, 73, respectively, while sandwiching them between the ring pieces 72, 72. This suspension string attachment ring 71 is provided with suspension cord attachment portions 74, 74 at two opposing positions, respectively.
One hanging cord 10 for two hanging cord attachment parts 74, 74
Each end can be connected to each other.

(Effect of idea) The insulating container of the present invention has the following effects.

(1) The upper end opening 13 of the container body 1 has a wide opening with approximately the same diameter as the inner diameter of the inner cylinder 12, and the upper end opening 1
Since the shoulder member 2 is detachably attached to the mouth edge of the container body 3, when the shoulder member 2 is removed from the container body 1, the upper end opening 13 of the wide mouth is opened.
Replenishment of liquids or ice chips, cleaning of the interior, etc. can be easily performed, and even ice chips of relatively large diameter can be freely accommodated. or,
Since the upper opening 13 of the container body 1 is wide, it can also be used to keep items other than liquids (for example, ice chips, canned drinks, etc.) warm, thereby expanding the range of uses.

(2) Since the shoulder member 2 is provided with a liquid pouring opening 21 that is opened and closed by the stopper 3, the shoulder member 2 cannot be removed even if the shoulder member 2 is removable. The liquid inside can be poured out simply by opening the stopper 3.

(3) Since the shoulder member 2 can be attached to and removed from the container body 1 together with the stopper 3, when the shoulder member 2 is removed, the stopper 3 can also be removed at the same time, and the stopper 3 can be removed. The special operations for this can be omitted.

(4) The shoulder member 2 is provided with a stopper 3 for closing the liquid pouring opening 21, and a cover member 4 which also serves as a stopper is screwed onto the shoulder member 2 in a detachable manner. and the cover body 4 can be attached, and the cover body 4 can be attached.
However, it has the function of protecting the upper surface of the shoulder member 2 (that is, the part that serves as the passage for the poured liquid) from dust, etc., and also serves as a tip for receiving liquid, simplifying the configuration and reducing the number of parts. can be achieved.

(5) Since the outer surface of the cover body 4, the outer surface of the shoulder member 2, and the outer surface of the outer cylinder 11 are configured to be continuous with each other without any step (i.e., a structure without a protruding part), it is easy to carry. Also, the storage space will be smaller.
