Description

Technical Field

[0001] This utility model relates to the field of food packaging technology, specifically to a container and beverage. Background Technology

[0002] For ease of storage or transportation, beverages are usually bottled into containers, forming drinks. Based on drinking temperature, beverages can be divided into hot drinks and cold drinks. Hot drinks are those consumed at temperatures above room temperature, while cold drinks are those consumed at temperatures below room temperature.

[0003] In practical applications, hot beverages need to be stored in insulated cabinets. When the temperature inside the insulated cabinet is high, the bottom of the hot beverage container will bulge, making the container unstable and unsuitable for storage. Utility Model Content

[0004] The problem this invention aims to solve is: how to improve the standing stability of a container.

[0005] To address the aforementioned problems, this utility model provides a container comprising: an integrally formed container body, a container bottom, and a first arc-shaped connecting portion;

[0006] The container bottom includes a second arc connecting part, a third arc connecting part, and a fourth arc connecting part; the second arc connecting part, the third arc connecting part, and the fourth arc connecting part are connected in sequence to form a concave structure that arches inward into the container;

[0007] One end of the first arc connecting part is connected to the container body, and the other end is connected to the second arc connecting part of the container bottom; the connection between the first arc connecting part and the second arc connecting part forms the annular standing surface of the container; the chamfer radius of the first arc connecting part, the second arc connecting part and the third arc connecting part is smaller than the chamfer radius of the fourth arc connecting part;

[0008] The depth of the concave structure matches the width of the annular standing surface, enabling the container to remain stable at a preset temperature.

[0009] In one possible embodiment, the first and second arc-shaped connecting portions both protrude outward from the container, while the third arc-shaped connecting portion is recessed inward from the container, and all three have the same chamfer radius.

[0010] In one possible embodiment, the chamfer radius of the first arc connecting portion, the second arc connecting portion, and the third arc connecting portion ranges from 2.8mm to 3.5mm.

[0011] In one possible embodiment, the width of the annular standing surface is 1mm to 1.4mm.

[0012] In one possible embodiment, the depth of the concave structure ranges from 15mm to 16mm.

[0013] In one possible embodiment, the fourth arc-shaped connecting portion is recessed into the container, and the chamfer radius of the fourth arc-shaped connecting portion ranges from 25mm to 32mm.

[0014] In one possible embodiment, the container bottom further includes: a first reinforcing groove that penetrates radially through the second arcuate connecting portion, the third arcuate connecting portion, and the fourth arcuate connecting portion, and a second reinforcing groove that penetrates radially through the second arcuate connecting portion and the third arcuate connecting portion.

[0015] In one possible embodiment, the concave structure further includes a central protrusion located in the central region of the concave structure, connected to the fourth arc connecting portion, and protruding into the container in the axial direction.

[0016] In one possible embodiment, the depth of the concave structure ranges from 15 mm to 17 mm.

[0017] This utility model embodiment also provides a beverage, the beverage comprising: any of the above-mentioned containers.

[0018] Compared with the prior art, the technical solution of this utility model embodiment has the following advantages:

[0019] By applying the solution of this utility model, a concave structure that arches inward into the container is formed by sequentially connecting a second, third, and fourth arc-shaped connecting part. This concave structure can withstand a certain axial pressure. By setting the chamfer radius of the first, second, and third arc-shaped connecting parts to be smaller than that of the fourth arc-shaped connecting part, and forming an annular standing surface of the container at the connection between the first and second arc-shaped connecting parts, the width of the annular standing surface can be made very narrow, thereby increasing the difficulty of deformation of the container's standing surface. At this time, by increasing the depth of the concave structure, the contents of the container can be more evenly and less distributed along the surface of the annular standing surface, thereby improving the standing stability of the container.

Detailed Implementation

[0025] Taking a 380ml full bottle of hot beverage as an example, when the temperature inside the warmer reaches 60 degrees Celsius, the bottom of the hot beverage container will bulge due to its poor pressure resistance. Specifically, when the pressure is around 0.4 bar, several bulges will appear on the standing surface of the bottom of the hot beverage container, causing it to bulge. Hot beverage containers with bulging bottoms are prone to instability and affect storage.

[0026] To address this problem, the present invention provides a container with a concave structure at the bottom. Furthermore, a second arc connecting part located at the edge of the concave structure and a first arc connecting part form an annular standing surface at the connection point. This allows the contents of the container to be distributed more evenly and less along the surface of the annular standing surface, thereby improving the standing stability of the container.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 1 and Figure 2 This utility model embodiment provides a container 100, which includes: an integrally formed container body 101, a container bottom 102, and a first arc connecting part 103;

[0029] The container bottom 102 includes a second arc connecting part 1021, a third arc connecting part 1022, and a fourth arc connecting part 1023; the second arc connecting part 1021, the third arc connecting part 1022, and the fourth arc connecting part 1023 are connected in sequence to form a concave structure that arches inward into the container 100.

[0030] One end of the first arc connecting part 103 is connected to the container body 101, and the other end is connected to the second arc connecting part 1021 of the container bottom 102; the connection between the first arc connecting part 103 and the second arc connecting part 1021 forms the annular standing surface 104 of the container; the chamfer radius of the first arc connecting part 103, the second arc connecting part 1021 and the third arc connecting part 1022 is smaller than the chamfer radius of the fourth arc connecting part 1023;

[0031] The depth of the concave structure matches the width of the annular standing surface 104, so that the container 100 remains standing stably at a preset temperature.

[0032] Since the second arc connecting portion 1021, the third arc connecting portion 1022, and the fourth arc connecting portion 1023 are connected in sequence to form a concave structure that arches inward into the container 100, this concave structure can withstand a certain axial pressure, thereby enhancing the compressive strength of the container 100. In addition, by setting the chamfer radius of the first arc connecting portion 103, the second arc connecting portion 1021, and the third arc connecting portion 1022 to be smaller than the chamfer radius of the fourth arc connecting portion 1023, and forming an annular standing surface 104 of the container at the connection between the first arc connecting portion 103 and the second arc connecting portion 1021, the width of the annular standing surface 104 can be made very narrow, thereby increasing the difficulty of deformation of the container standing surface. At this time, by increasing the depth of the concave structure, the contents of the container 100 can be more evenly distributed along the surface of the annular standing surface 104, thereby improving the standing stability of the container.

[0033] In a specific implementation, container 100 may further include a container opening 105. The container opening 105 is located at one end of the container body 101 along the axial direction, and the container bottom 102 is located at the other end of the container body 101 along the axial direction. Container 100 can be made of plastic. This container 100 can be used to hold beverages, such as coffee or milk tea. After the beverage is filled into the container, it can be stored in an insulated cabinet.

[0034] In a specific implementation, a plurality of first protrusions 1011 may be provided on the surface of the container body 101 near the container opening 105. The first protrusions 1011 extend along the axial direction of the container body 101 and protrude from the surface of the container body 101. There is a first concave groove between adjacent first protrusions 1011, thereby improving the strength of the end of the container body 101 near the container opening 105.

[0035] In a specific implementation, a first circumferential groove 1013 can be provided at the end of the first protrusion 1011 and in the middle area of ​​the container body 101. This first circumferential groove 1013 is recessed into the container 100 along the surface of the container body 101. The connection between the first circumferential groove 1013 and the end of the first protrusion 1011 has a first chamfer, and the connection between the first circumferential groove 1013 and the middle area of ​​the container body 101 has a second chamfer. The angle between the first chamfer and the horizontal plane is α1, and the angle between the second chamfer and the horizontal plane is α2, where α1 < α2. This enhances both the circumferential strength and compressive strength of the container body 101. Typically, α1 can be 30°, and α2 can be 40°.

[0036] In a specific implementation, a plurality of second protrusions 1012 may be provided on the surface of the container body 101 near the container bottom 102. The second protrusions 1012 extend along the axial direction of the container body 101 and protrude from the surface of the container body 101. There is a second concave groove between adjacent second protrusions 1012, thereby improving the strength of the end of the container body 101 near the container bottom 102.

[0037] In a specific implementation, a second circumferential groove 1014 can be provided at the end of the second protrusion 1012 and in the middle region of the container body 101. This second circumferential groove 1014 is recessed into the container 100 along the surface of the container body 101. The connection between the second circumferential groove 1014 and the end of the second protrusion 1012 has a third chamfer, and the connection between the second circumferential groove 1014 and the middle region of the container body 101 has a fourth chamfer. The angle between the third chamfer and the horizontal plane is β1, and the angle between the fourth chamfer and the horizontal plane is β2, where β1 < β2. This enhances both the circumferential strength and compressive strength of the container body 101. Typically, β1 can be 40°, and β2 can be 30°.

[0038] In a specific implementation, the container bottom 102 includes a concave structure formed by a second arc-shaped connecting portion 1021, a third arc-shaped connecting portion 1022, and a fourth arc-shaped connecting portion 1023. The first arc-shaped connecting portion 103 and the second arc-shaped connecting portion 1021 both protrude outwards from the container 100, while the third arc-shaped chamfered connecting portion 1022 is recessed inwards from the container 100. The second arc-shaped connecting portion 1021 is located at the edge of the concave structure and serves to connect to the first arc-shaped connecting portion 103. From the edge of the concave structure to its center, the slope of the concave structure gradually decreases.

[0039] In an embodiment of this utility model, the connection between the first arc connecting portion 103 and the second arc connecting portion 1021 serves as the annular standing surface 104 of the container 100. The chamfer radii of the first arc connecting portion 103 and the second arc connecting portion 1021 are relatively small, thereby making both the first arc connecting portion 103 and the second arc connecting portion 1021 relatively steep, resulting in a narrower width w1 for the annular standing surface 104.

[0040] In specific implementation, the width w1 of the annular standing surface 104 is in the range of 1mm to 1.4mm. For example, the width w1 of the annular standing surface 104 can be 1mm, 1.2mm or 1.4mm.

[0041] Unlike existing technologies that improve container stability by increasing the width of the standing surface, this invention reduces the width of the annular standing surface 104. This makes the narrower annular standing surface 104 more difficult to deform, thereby reducing or even preventing the annular standing surface 104 from bulging at higher temperatures. Simultaneously, increasing the depth of the concave structure makes the container more stable while maintaining the same 100-gram weight.

[0042] In one embodiment of this utility model, the chamfer radii of the first arc connecting portion 103, the second arc connecting portion 1021, and the third arc connecting portion 1022 can be the same. Specifically, the chamfer radius can be set to a range of 2.8mm to 3.5mm. For example, the chamfer radii of the first arc connecting portion 103, the second arc connecting portion 1021, and the third arc connecting portion 1022 can all be 2.8mm, 3mm, or 3.1mm.

[0043] It should be noted that the arc length of the first arc connecting portion 103 can be greater than the arc length of the second arc connecting portion 1021 and the arc length of the third arc connecting portion 1022. The arc length of the second arc connecting portion 1021 can be equal to the arc length of the third arc connecting portion 1022. This allows for the formation of a narrower annular standing surface 104. The reduced width of the annular standing surface 104 reduces the distance w2 from its centerline to the container body 101, thereby reducing the amount of contents distributed on the annular standing surface 104 and thus decreasing the pressure on the container bottom 102. w2 can typically be less than 7 mm, for example, w2 = 5.8 mm.

[0044] At this point, a tangent is drawn to the second arc connecting part 1021 through the center point of the arc length. The angle λ1 between this tangent and the central axis of the container 100 is less than 35°, for example, λ1 = 30°. The second arc connecting part 1021 is steeper, and the annular standing surface 104 is narrower.

[0045] In a specific implementation, the fourth arc-shaped connecting portion 1023 is recessed into the container 100. The chamfer radius of the fourth arc-shaped connecting portion 1023 is usually large, which makes the slope of the concave structure gentler. This allows the pressure of the contents of the container 100 on the bottom 102 of the bottle container to be concentrated on the surface of the concave structure, enhancing the stability of the center of the container 100 and improving the standing stability of the container.

[0046] In some embodiments, the chamfer radius of the fourth arc connecting portion 1023 ranges from 25mm to 32mm. For example, the chamfer radius of the fourth arc connecting portion 1023 can be 27mm, 30mm, etc.

[0047] In specific implementation, in order to further enhance the compressive strength of the container bottom 102, the container bottom 102 further includes: a first reinforcing groove 1024 that penetrates the second arc connecting portion 1021, the third arc connecting portion 1022 and the fourth arc connecting portion 1023 radially, and a second reinforcing groove 1025 that penetrates the second arc connecting portion 1021 and the third arc connecting portion 1022 radially.

[0048] In a specific implementation, the first reinforcing groove 1024 is recessed into the container 100 relative to the surface of the concave structure, forming a protrusion that bulges radially into the container 100 along the concave structure. The first reinforcing groove 1024 includes a first reinforcing section distributed in the second arc-shaped connecting portion 1021, a second reinforcing section distributed in the third arc-shaped connecting portion 1022, and a third reinforcing section distributed in the fourth arc-shaped connecting portion 1023. Each reinforcing section is arc-shaped and has the same chamfer radius as the arc-shaped connecting portion it belongs to.

[0049] In a specific implementation, the second reinforcing groove 1025 is also recessed into the container 100 relative to the surface of the concave structure, forming a protrusion that bulges radially into the container 100 along the concave structure. The difference is that the length of the second reinforcing groove 1025 is less than the length of the first reinforcing groove 1024. The second reinforcing groove 1025 includes a fourth reinforcing segment distributed in the second arc-shaped connecting portion 1021 and a fifth reinforcing segment distributed in the third arc-shaped connecting portion 1022. Each reinforcing segment is arc-shaped and has the same chamfer radius as the arc-shaped connecting portion it belongs to.

[0050] By setting two reinforcing grooves of different lengths, compared to setting only one length of reinforcing groove, the weight and cost of the container itself can be reduced, while ensuring the strength of the container bottom.

[0051] In some embodiments, refer to Figure 2 The first reinforcing groove 1024 and the second reinforcing groove 1025 are alternately distributed along the circumference of the container bottom 102. The number of the first reinforcing groove 1024 and the second reinforcing groove 1025 can be the same. The connection between the first reinforcing groove 1024 and the concave structural surface is a chamfered connection.

[0052] In a specific implementation, to enhance the compressive strength of the container bottom 102, the concave structure may further include a central protrusion 1026. The central protrusion 1026 is located in the central region of the concave structure, connected to the fourth arc connecting portion 1023, and protrudes into the container 100 along the axial direction.

[0053] In some embodiments, the concave structure may further include a fifth arc connecting portion 1027, which is connected to the fourth arc connecting portion 1023 and extends radially along the concave structure. The chamfer radius of the fifth arc connecting portion 1027 is smaller than that of the fourth arc connecting portion 1023, thereby forming a structure that is concave into the container 100. The chamfer radius of the fifth arc connecting portion 1027 can range from 10 mm to 12 mm, for example, the chamfer radius of the fifth arc connecting portion 1027 can be 11.6 mm. In this case, the central protrusion 1026 is connected to the fifth arc connecting portion 1027, thereby allowing the concave structure to quickly adjust its concave shape to connect with the central protrusion 1026 when approaching it, thus enhancing the strength of the connection between the central protrusion 1026 and the fifth arc connecting portion 1027.

[0054] Specifically, the central protrusion 1026 forms an axially protruding boss relative to the fifth arc connecting portion 1027. This boss may include a flange 1026a and a planar area 1026b. The flange 1026a protrudes inward relative to the planar area 1026b, thereby enhancing the compressive strength of the central protrusion 1026. The distance h2 from the flange 1026a to the plane containing the top of the fifth arc connecting portion 1027, which is the height by which the flange 1026a protrudes inward relative to the top of the fifth arc connecting portion 1027, can be set according to the actual width of the annular standing surface 104. For example, when the width of the annular standing surface 104 is 1.2 mm, h2 can be set to 4.1 mm, thereby enabling the container to resist (0.3 ± 0.1) bar pressure under a relatively light weight.

[0055] In practice, the flange 1026a is inclined relative to the centerline of the container 100, and the angle λ1 between the outer edge of the flange 1026a and the centerline of the container 100 is small. This allows for the increase of the height of the flange 1026a while ensuring the compressive strength of the central protrusion 1026, thereby increasing the depth of the concave structure. For example, λ1 can be set to 25°.

[0056] In a specific implementation, one end of the flange 1026a can be chamfered to the fourth arc connecting part 1023. The chamfer radius corresponding to the chamfered connection between the flange 1026a and the fourth arc connecting part 1023 is relatively small, for example, it can be 3mm.

[0057] In the specific implementation, the distance between the top of the flange 1026a and the standing surface 104 is the depth h1 of the concave structure. The depth of the concave structure can be set according to the width of the annular standing surface 104, as long as it can ensure that the container 100 can remain stable at high temperatures (e.g., 60°C).

[0058] Specifically, the depth of the concave structure can range from 15mm to 17mm, for example, the depth of the concave structure can be 15mm, 15.8mm, 16mm or 17mm. This can reduce costs and the weight of the container itself while ensuring that the container bottom 102 has pressure resistance.

[0059] Using the above-mentioned container, stronger pressure resistance can be achieved under the same weight. Specifically, it can stand stably in a heat exchanger at around 60 degrees Celsius with a lighter weight (e.g., 4.5g ± 0.4g). Furthermore, the shallow indentation at the bottom of the container has minimal impact on the overall appearance of the container, and there is no need to increase the height of the container due to an excessively deep indentation.

[0060] This utility model embodiment also provides a beverage, which includes any of the containers described above.

[0061] In practice, the container can hold beverages such as coffee and milk tea. The bottom of the beverage container has two or more annular sections, and the annular sections are connected to the standing surface and adjacent annular sections by stepped transition sections, and are provided with reinforcing grooves to improve strength, thereby maintaining stability in a warming cabinet at around 60 degrees Celsius.

[0062] Although the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
