[0043] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0044] As one embodiment of the present invention, for example, for having Figures 1-9 The lidded container 100 of the lid unit 1 shown will be described.

[0045] also, Figure 1 This is a perspective view of a lidded container 100 having a lid unit 1. Figure 2 This is a perspective view showing the state where the lid 8 of the covered container 100 has been removed. Figure 3 This is a cross-sectional view of a covered container 100. Figure 4 It is a three-dimensional view of the inside of the inlet 10 of the covered container 100. Figure 5 Based on Figure 4 The figure shows a cross-sectional view of the covered container 100 with line segment AA. Figure 6 This is a perspective view of the cover 8 of cover unit 1 as seen from the front. Figure 7 This is a perspective view of the cover 8 of cover unit 1 as seen from the rear. Figure 8 This is a front view of the cover 8 of the cover unit 1 as seen from the front. Figure 9 This is a top view of the cover body 8 of the cover unit 1 viewed from below.

[0046] like Figure 1 and Figure 2 As shown, the lidded container 100 of this embodiment includes a lid unit 1 of this embodiment and a container body 2 for mounting the lid unit 1. The lidded container 100 of this embodiment is a tabletop pitcher (beverage container) that can keep beverages (liquids) contained in the container body 2 warm or cold by means of the container body 2 having a vacuum insulation structure.

[0047] Furthermore, in the lidded container 100 of this embodiment, the side with the injection outlet 10 (described later) is designated as the "front side", and the side with the handle portion 11 located on the opposite side of the injection outlet 10 is designated as the "rear side".

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, the container body 2 is composed of a double-layered container. This double-layered container consists of an outer container 3, which is a bottomed cylindrical shape made of, for example, stainless steel, and an inner container 4. The opening edges of the inner container 4 are joined together with the inner container 3 inside the outer container. Furthermore, a vacuum insulation layer 5 is provided between the outer container 3 and the inner container 4. The vacuum insulation layer 5 can be formed, for example, by blocking an exhaust port located on the bottom surface of the outer container 3 within a chamber that has been depressurized (evacuated) to a high vacuum.

[0049] The container body 2 has: a generally circular bottom 2a; a generally cylindrical cylindrical body 2b rising from the outer periphery of the bottom 2a; a generally cylindrical neck 2c that is tapered at the upper side of the cylindrical body 2b; and a shoulder 2d that gradually tapes towards the neck 2c from the cylindrical body 2b. The upper end of the neck 2c has a circular opening, serving as the upper opening 2e of the container body 2. Furthermore, the inner circumferential surface of the neck 2c is tapered compared to the inner circumferential surface of the cylindrical body 2b. Additionally, an annular protrusion 6 is provided protruding along the entire circumference of the inner circumferential surface of the neck 2c.

[0050] Furthermore, the container body 2 of this embodiment has an overall cylindrical shape with a bottom and a tapered diameter that narrows from the lower side to the upper side of the cylindrical part 2b. However, the shape of the container body 2 is not particularly limited and can be appropriately modified according to size, design, etc. In addition, the outer peripheral surface of the container body 2 can be coated or printed.

[0051] like Figures 3-9 As shown, the cover unit 1 of this embodiment includes: a cover body 7, which is installed on the neck portion 2c and shoulder portion 2d of the container body 2; and a cover 8, which is inserted into the inner side of the cover body 7 from the liquid inlet 7a provided on the cover body 7.

[0052] like Figure 1 , Figure 2 and Figure 3 As shown, the cap body 7 is, for example, a shoulder member made of heat-resistant resin, forming a circular liquid inlet 7a that communicates with the inside of the container body 2, and is installed on the neck 2c of the container body 2 via the opening edge sealant 9A and the shoulder sealant 9B.

[0053] The opening edge seal 9A and the shoulder seal 9B are annular sealing components that seal the neck portion 2c and shoulder portion 2d of the container body 2 with the cap body 7. They are made of heat-resistant rubber such as silicone rubber, elastic components such as elastomers, etc.

[0054] With the neck portion 2c, shoulder portion 2d and upper opening portion 2e of the container body 2 covered by the aforementioned opening edge filling member 9A and shoulder filling member 9B, the cap body 7 is fitted into the neck portion 2c of the container body 2 in a manner coplanar with the outer peripheral surface of the cylindrical portion 2b of the container body 2.

[0055] When the sealing member 9A covers the upper end of the neck portion 2c, it seals the neck portion 2c of the container body 2 and the cap body 7. Furthermore, the inner circumference of the sealing member 9A extends to near the lower end of the inner circumference of the cap body 7. This prevents beverage from entering the gap between the neck portion 2c of the container body 2 and the cap body 7, and prevents leakage from that gap.

[0056] On the other hand, the shoulder seal 9B, located at least between the shoulder 2d of the container body 2 and the lower surface of the cap body 7 opposite to the shoulder 2d, seals the gap between the shoulder 2d of the container body 2 and the cap body 7. This prevents water or other substances from seeping into the gap between the shoulder 2d of the container body 2 and the cap body 7 during cleaning.

[0057] The lid body 7 has an outlet 10 for pouring beverages from the container body 2 to the outside, and a handle 11 for the user to hold.

[0058] The injection outlet 10 is located on the side of the front of the cap body 7 and is configured to protrude from one end of the liquid inlet 7a in the direction of widening. Specifically, the injection outlet 10 is composed of a groove that protrudes forward while tilting obliquely upward from the side of the front of the cap body 7.

[0059] The handle 11 is configured to protrude rearward and extend downward from the side opposite to the inlet 10, i.e., the rear side of the cap body 7. Furthermore, the handle 11 is not necessarily limited to such a shape, and its shape can be appropriately modified.

[0060] like Figures 1-9 As shown, the cover 8 is a plug with a heat-insulating structure, which is installed on the cover body 7 in a way that allows the opening 7b to be opened and closed freely.

[0061] Specifically, such as Figure 2 and Figure 3 As shown, the cover 8 includes, for example, an upper cover 12 made of heat-resistant resin and a middle plug 13. The upper cover 12 covers the upper part of the cover body 7, has a circular shape corresponding to the liquid inlet 7a of the cover body 7, and is formed into a flat plate. The middle plug 13 is a part embedded inside the cover body 7, has a bottomed, generally cylindrical shape, and is integrally mounted to the center of the lower surface of the upper cover 12 by means of welding or the like. In addition, a heat insulation element S made of foamed polyurethane resin is disposed inside the middle plug 13 as a heat insulation layer, for example. Alternatively, air (void) may be used instead of the aforementioned heat insulation element S as a heat insulation layer.

[0062] Additionally, in the cover 8, such as Figures 3-9 As shown, a stepped portion 14 is provided around the entire circumference between the plug 13, which is inserted into the inner side of the cap body 7 from the liquid inlet 7a, and the plug 13. On the other hand, an abutting surface 7c, which abuts against the stepped portion 14, is provided on the inner side of the cap body 7.

[0063] In the cover unit 1 of this embodiment, as Figure 1 and Figure 3As shown, when the plug 13 is inserted into the inner side of the cover body 7 from the liquid inlet 7a, the stepped portion 14 abuts against the contact surface 7c of the cover body 7, and the opening 7b can be covered by the cover body 8.

[0064] In addition, such as Figures 1-3 and Figures 6-9 As shown, the cover 8 has a fitting protrusion 15 that protrudes rearward from the rear side of the center bolt 13. The fitting protrusion 15 is configured to protrude in a flat, plate-like shape opposite to the upper surface of the handle portion 11. On the other hand, a fitting recess 16 is provided on the upper surface of the handle portion 11, which is fitted with the fitting protrusion 15. When fitted into the fitting recess 16, the fitting protrusion 15 is substantially coplanar with the upper surface of the handle portion 11.

[0065] In the cover unit 1 of this embodiment, when the cover body 8 is inserted into the inside of the cover body 7, the fitting protrusion 15 is fitted into the fitting recess 16, making it easy to align. In addition, when the user holds the handle 11, by pressing the fitting protrusion 15 fitted into the fitting recess 16 with the user's finger, the cover body 8 inserted into the inside of the cover body 7 from the liquid inlet 7a can be prevented from falling off the cover body 7.

[0066] like Figures 3-9 As shown, the cover 8 has: a liquid channel 17, which together with the inlet 10 forms a flow path R for the beverage to flow out of the container body 2; and a venting channel 18, which introduces external air into the interior of the container body 2.

[0067] The fluid passage 17 is located on the side of the front side of the plug 13, and is configured to be cut vertically from the side opposite to the inlet 10 to the bottom surface. In addition, the fluid passage 17 has the following groove shape: the width W2 of the lower end of the plug 13 facing the bottom surface is greater than the width W1 of the upper end of the plug 13 facing the side surface, and the depth D2 of the lower end of the plug 13 facing the bottom surface is greater than the depth D1 of the upper end of the plug 13 facing the side surface.

[0068] Furthermore, width W1 is the circumferential width of the eaves 19, described later. Width W2 is the circumferential width of the fluid channel 17 extending from the bottom surface of the central plug 13. Additionally, depth D1 is the distance between the upper part 17a of the bottom surface of the fluid channel 17 and the inner surface of the inlet 10. Depth D2 is the distance between the side part 17b of the bottom surface of the fluid channel 17 and the fluid inlet 7a.

[0069] In the cover unit 1 of this embodiment, as Figure 3 As shown, with the plug 13 embedded inside the cover body 7 from the liquid inlet 7a, a flow path R is formed from the injection outlet 10 to the liquid channel 17.

[0070] In addition, such as Figure 4 and Figure 5As shown, a roughly U-shaped eave 19 is provided on the side of the plug 13 facing the inlet 10, protruding slightly forward, and surrounds the upper end of the liquid passage trough 17. In addition, the eave 19 is configured to extend downward to the position where a step portion 14 is formed.

[0071] In the cap unit 1 of this embodiment, with the stepped portion 14 in contact with the contact surface 7c of the cap body 7, both ends of the rim 19 are in contact with the inner surface of the inlet 10. Therefore, when beverage is poured out of the container body 2 from the inlet 10, the contact surface 7c and the stepped portion 14 can easily stop water flow, preventing the beverage from flowing towards the opening 7b. Furthermore, beverage flowing from the liquid inlet 7a along the contact surface 7c to the inlet 10 can be prevented from disrupting the flow of beverage dispensed from the liquid channel 17.

[0072] like Figure 3 , Figures 6-9 As shown, the venting groove 18 is located on the side opposite to the liquid channel 17, that is, on the side behind the middle plug 13, and is configured to cut the lower part of the fitting protrusion 15 in the vertical direction between it and the step part 14.

[0073] In the cap unit 1 of this embodiment, when the beverage inside the container body 2 is poured out from the inlet 10, external air is introduced into the interior of the container body 2 through the venting groove 18. This prevents pulsation caused by air flowing in from the liquid channel 17 side, and allows the beverage inside the container body 2 to be poured out smoothly from the inlet 10. Furthermore, with the cap 8 embedded inside the cap body 7, the venting groove 18 is covered by the fitting protrusion 15 and not exposed to the outside, thus achieving an aesthetically pleasing cap unit 1.

[0074] In the lidded container 100 of this embodiment, which has the lid unit 1 with the structure described above, beverages flowing out of the container body 2 through the flow path R can be easily dispensed from the dispensing outlet 10.

[0075] Specifically, in the cover unit 1, the aforementioned liquid passage groove 17 is configured to be cut from the side surface of the middle plug 13, which is opposite to the injection outlet 10 and the liquid passage 7a, to the bottom surface. Furthermore, the liquid passage groove 17 has the following groove shape: the width W2 of the lower end of the middle plug 13 facing the bottom surface is greater than the width W1 of the upper end of the middle plug 13 facing the side surface, and the depth D2 of the lower end of the middle plug 13 facing the bottom surface is greater than the depth D1 of the upper end of the middle plug 13 facing the side surface; the cross-sectional area of ​​the liquid passage groove 17 gradually decreases towards the injection outlet 10.

[0076] Therefore, by increasing the speed of the beverage flowing in the liquid channel 17, the energy of friction between the beverage and the liquid channel 17, which could cause disturbances during discharge, can be suppressed, allowing the beverage in the container body 2 to be smoothly poured out from the dispensing outlet 10. Furthermore, it prevents the beverage from pulsating and scattering in the surrounding area.

[0077] Furthermore, in the cover unit 1 of this embodiment, an eaves 19 is provided surrounding the upper end of the aforementioned liquid passage 17. This eaves 19 adjusts the flow of beverage from the upper end of the liquid passage 17 to the dispensing outlet 10. Additionally, the eaves 19 prevent beverage flowing from the upper end of the liquid passage 17 facing the dispensing outlet 10 from flowing towards the upper cover 12, or prevents beverage flowing from the liquid passage 7a along the contact surface 7c to the dispensing outlet 10 from disrupting the flow of beverage dispensed from the liquid passage 17.

[0078] In addition, in the cover unit 1 of this embodiment, the step portion 14 abuts against the contact surface 7c, which can easily stop water and prevent beverages from flowing to the opening portion 7b.

[0079] Furthermore, in the cover unit 1 of this embodiment, when the cover body 8 is embedded inside the cover body 7, the fitting protrusion 15 fits into the fitting recess 16, thereby making it easier to align the flow path R formed by the injection outlet 10 and the liquid channel 17.

[0080] As described above, in the cover unit 1 of this embodiment, the beverage can be prevented from scattering due to the pulsation of the beverage flowing from the inlet 10, thus maintaining the hygiene of the surrounding area and the cover unit 1.

[0081] Furthermore, in the lid unit 1 of this embodiment, the simple structure of the lid body 7 and lid 8 described above improves its cleanability. Therefore, in the lidded container 100 of this embodiment, by providing such a lid unit 1, the ease of use can be further improved.

[0082] Furthermore, the present invention is not necessarily limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

[0083] For example, in the above embodiment, a lidded container 100 applied to the above-described desktop kettle is illustrated, but the present invention can also be widely applied to lidded containers having a lid unit installed on the container body with an upper opening.

[0084] Furthermore, in the above embodiments, a covered container 100 with heat preservation and cold preservation functions is exemplified by a container body 2 having the above-described vacuum insulation structure, but the present invention can also be applied to covered containers having a container body without a vacuum insulation structure.
