Description

TECHNICAL FIELD

[0001] The present application relates generally to a liquid container suitable for containing a liquid such as a pesticide, herbicide, etc. BACKGROUND

[0002] With the rapid development of modern agriculture, pesticides and herbicides are increasingly widely used in crop planting. In order to ensure the correct use of pesticides and herbicides, effectively improve the yield of agricultural products and reduce environmental pollution, it has become a trend to precisely manage the use of pesticides and herbicides. Such precise management not only requires farmers to reasonably select and use pesticides, but also requires effective traceability and record-keeping of the storage, transportation and use of pesticides.

[0003] In this case, more and more containers are designed to have the function of storing and reading the information of the liquid inside. These containers usually mark the key information of the liquid inside the container, such as the type, production date, concentration ratio, etc., through labels or the like arranged on the surface, so as to quickly identify and manage during use. However, these technologies, although they can improve the management efficiency of liquid information, also have significant defects.

[0004] Since the label information is easy to be scanned, copied or stolen, it can lead to the misuse, forgery or illegal acquisition of the content information of the container. Especially in sensitive products such as pesticides, herbicides, etc., such information leakage can cause damage to the commercial interests of the manufacturer and even endanger public safety.

[0005] The existing labels are prone to falling off, wearing out or failing in long-term use or in harsh environments (such as high humidity, high temperature, strong light exposure), thereby affecting the accuracy of information reading.

[0006] Some technologies (such as static two-dimensional code labels) do not support dynamic updating, and once the content of the container changes, the information of the original label is difficult to modify or update, reducing the practicality and flexibility of the label.

[0007] Therefore, how to design a safer, more efficient and durable label or the like on the container for storing and reading the liquid information inside the container while effectively preventing information theft is a problem to be solved in the current technical field. SUMMARY

[0008] One of the purposes of the present application is to provide a liquid container that can overcome at least one of the defects in the prior art.

[0009] One of the purposes of the present application is to provide a liquid container that can effectively prevent the label from being lost or stolen.

[0010] Another purpose of the present application is to provide a liquid container that can reduce the influence of the liquid inside the container on the label.

[0011] According to a first aspect of the present application, there is provided a liquid container comprising:

[0012] a container body having an upper joint; and

[0013] a top cover coupled to the container body at the upper joint, such that the top cover and the container body define an inner space of the liquid container;

[0014] wherein the liquid container further comprises a tag disposed on an inner surface of the top cover or on an inner surface near the upper joint of the container body, such that the tag faces the inner space.

[0015] By disposing the tag inside the liquid container, the risk of being torn off and stolen can be avoided. By disposing the tag on an inner surface of the top cover or on an inner surface near the upper joint of the container body, the influence of the liquid inside the liquid container on the tag can be avoided or reduced, so that the tag can operate normally.

[0016] In some embodiments of the liquid container, the container body and the top cover are integrally formed.

[0017] The integrally formed container body and top cover can prevent the top cover from being removed directly from the container body to expose the tag, thereby further enhancing the risk of preventing the tag from being torn off and stolen.

[0018] In some embodiments of the liquid container, the tag is a radio frequency identification tag.

[0019] In the case of a tag device inside the liquid container, a radio frequency identification tag can be advantageously employed, so that the user can directly read the information stored by the tag through a reader outside the liquid container. In this way, both the tag can be prevented from being torn off or stolen, and the information of the tag can be read conveniently and quickly.

[0020] In some embodiments of the liquid container, the tag is disposed on a central region of the inner surface of the top cover, and away from the opening of the liquid container, preventing easy access to the tag inside the liquid container through the opening.

[0021] In some embodiments of the liquid container, the tag is attached to the top cover or the container body, making installation simple and convenient.

[0022] In some embodiments of the liquid container, the liquid container is provided with a positioning structure configured to hold and fix the tag. The positioning structure can keep the tag attached to the inner surface of the liquid container, preventing it from falling off, avoiding the risk of the tag falling into the liquid and failing.

[0023] In some embodiments of the liquid container, the liquid container is provided with a positioning groove in which the label is embedded.

[0024] In some embodiments of the liquid container, the positioning groove is configured such that, when the label is embedded in the positioning groove, the label is flush with or recessed into an inner surface of the liquid container.

[0025] The positioning groove can be used to hold and secure the label, preventing the label from falling off, while the positioning groove enables the label to be flush with or recessed into an inner surface of the liquid container, making it more difficult to discover the presence of the label, further increasing the risk of the label being torn off and stolen.

[0026] In some embodiments of the liquid container, the label is covered with a protective element that separates the label from the interior space. The protective element can protect the label from the liquid contained in the liquid container.

[0027] In some embodiments of the liquid container, the liquid container is provided with a shielding member provided on an outer surface of the liquid container at a position corresponding to the label.

[0028] In some embodiments of the liquid container, the diameter of the top cover is greater than or equal to 500 mm, and / or the volume of the liquid container is greater than or equal to 150 liters. BRIEF DESCRIPTION OF DRAWINGS

[0039] The present application will be described with reference to the attached drawings, which show several embodiments of the application. It should be understood, however, that the application can be presented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and fully convey the scope of the application to those skilled in the art. It should also be understood that the embodiments disclosed herein can be combined in various ways, providing more additional embodiments.

[0040] It should be understood that, in all the drawings, the same reference numerals indicate the same elements. In the drawings, the dimensions of certain features can be exaggerated for clarity.

[0041] It should be understood that the terminology used in the specification is for the purpose of describing particular embodiments only and is not intended to limit the application. All terms used in the specification, unless otherwise defined, have the meanings commonly used by those in the art. Well-known functions or constructions can not be described in detail for the sake of conciseness and / or clarity.

[0042] As used in the specification, the singular forms "a," "an," and "the" include plural references unless the context clearly dictates otherwise. As used in the specification, the terms "comprises," "comprising," and "including" indicate the presence of the stated features but do not preclude the presence or addition of one or more other features. As used in the specification, the term "and / or" includes any and all combinations of one or more of the associated listed items. As used in the specification, the terms "between" and "between about" shall be interpreted as including the values of X and Y. As used in the specification, the term "between about X and Y" means "between about X and about Y," and as used in the specification, the term "from about X to Y" means "from about X to about Y."

[0043] In the specification, when an element is referred to as being "on", "attached", "connected", "coupled", or "contacted" to another element, it can be directly on, attached, connected, coupled, or contacted to the other element or intervening elements can be present. In contrast, when an element is referred to as being "directly on", "directly attached", "directly connected", "directly coupled", or "directly contacted" to another element, there are no intervening elements present. In the specification, when an element is referred to as being "adjacent" to another element, it can mean that the element has a portion that overlaps with the adjacent element or a portion that is above or below the adjacent element.

[0044] In the specification, spatially relative terms such as "upper", "lower", "left", "right", "front", "back", "top", "bottom", and the like can be used for describing an element's relationship to another element in a drawing. It is to be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation, in addition to the orientation depicted in the drawings. For example, if a device is inverted from the orientation depicted in the drawing, elements described as being "below" or "beneath" other elements would then be oriented "above" the other elements. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors can be interpreted accordingly.

[0045] With the rapid development of modern agriculture, pesticides and herbicides are increasingly widely used in crop planting. In order to ensure the correct use of pesticides and herbicides, effectively improve the yield of agricultural products and reduce environmental pollution, precise management of the use of pesticides and herbicides has become a trend. Such precise management not only requires farmers to reasonably select and use pesticides, but also requires effective tracing and recording of the storage, transportation and use process of the pesticides.

[0046] In this case, more and more containers are designed to have the function of storing and reading internal liquid information. These containers usually mark the key information such as the type of liquid, the production date, the concentration ratio, etc. in the container through the label or the like arranged on the surface, so as to quickly identify and manage during use. However, although these technologies can improve the management efficiency of liquid information, they also have significant defects.

[0047] The tag can be, for example, a two-dimensional code, a radio frequency identification (RFID) tag, etc., which is usually arranged on the outer surface of the container for easy installation and reading. However, the tag arranged on the outer surface of the container can be easily torn off or stolen. In the case where the tag is torn off or worn or fallen off, the information in the container cannot be read subsequently, and the container cannot be normally and effectively managed. Since the tag information can be easily scanned, copied or stolen, it can lead to the misuse, forgery or illegal acquisition of the information of the contents of the container. Especially in sensitive products such as pesticides, herbicides, etc., such information leakage can cause damage to the commercial interests of the manufacturer, and even endanger public safety.

[0048] Some technologies (such as static two-dimensional code tags) do not support dynamic updating, and once the contents of the container change, the information of the original tag is difficult to modify or update, reducing the practicability and flexibility of the tag.

[0049] Therefore, the present application attempts to design a safer, more efficient and durable tag or the like on the liquid container for storing and reading the information of the liquid in the container, while effectively preventing the information from being.

[0050] Since the tag arranged on the outer surface of the container can be easily torn off or stolen, the present application proposes to arrange the tag inside the container, so that it is difficult to access the tag from the outside, ensuring the safety of the tag. In the case where the tag is arranged inside the container, a radio frequency identification tag can be considered to facilitate the reading of information. On the other hand, in the case where the tag is arranged inside the container, since the container contains liquid, such as pesticide, herbicide and other medicaments, there can be a certain corrosive effect on the tag, and in the case where the tag is in contact with the liquid, there can also be a certain obstacle to the reading of the tag, therefore, the present application proposes to arrange the tag on the upper part of the container. Since the container is usually placed vertically when containing liquid, in most cases, the liquid is not completely filled in the entire container, and therefore there is a certain space above the liquid surface. When the tag is in this space, it can reduce or try to avoid contact with the liquid. Even in the case where the liquid touches the tag, for example, when the container is overturned or shaken or vibrated during transportation, as long as the container is finally in a normal placement state (for example, placed in a warehouse and left standing), the liquid can leave the tag, so that the tag can operate normally and prolong the life of the tag.

[0051] The liquid container according to some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0052] According to some embodiments of the present application, a liquid container 1 can include a container body 10 having an upper junction 16, and a top cover 20 coupled to the container body 10 at the upper junction 16 such that the top cover 20 and the container body 10 define an interior space 2 of the liquid container 1. The liquid container 1 can further include a label 30 which can be disposed on an inner surface 22 of the top cover 20 or on an inner surface 18 near the upper junction 16 of the container body 10 such that the label 30 faces the interior space 2.

[0053] As shown in FIG. 1, a perspective view of a liquid container 1 according to some embodiments of the present application is shown. The liquid container 1 can include a container body 10 and a top cover 20 which can be coupled to the container body 10 at an upper junction 16 so as to define an interior space 2 of the liquid container 1 by the top cover 20 and the container body 10 for containing or holding a liquid such as a pesticide or herbicide. Figure 1 Figure 2 As shown in FIG. 1, a perspective view of a liquid container 1 according to some embodiments of the present application is shown. The liquid container 1 can include a container body 10 and a top cover 20 which can be coupled to the container body 10 at an upper junction 16 so as to define an interior space 2 of the liquid container 1 by the top cover 20 and the container body 10 for containing or holding a liquid such as a pesticide or herbicide.

[0054] The container body 10 can include a side wall 12 and a bottom wall 14 which are coupled together at a lower junction 13 such that, when the top cover 20 is coupled to the container body 10, a closed container can be formed.

[0055] The liquid container 1 can have any suitable shape such as a generally cylindrical or a parallelepiped shape. In the illustrated embodiments, the liquid container 1 is shown to have a cylindrical shape, but it will be appreciated by those skilled in the art that any other suitable shape is possible and the cylindrical shape is merely exemplary and not limiting. For the sake of simplicity and clarity of description, the description herein can be directed to the cylindrical shape, but it will be appreciated that the features described herein are equally applicable to liquid containers of other shapes. In the case where the liquid container 1 is of a cylindrical shape, the top cover 20 can be circular, the bottom wall 14 can be circular, and the side wall 12 forms a generally cylindrical shape. In the case where the liquid container 1 is of a parallelepiped shape, the top cover 20 can be rectangular, the bottom wall 14 can be rectangular, and the side wall 12 forms a generally prismatic shape.

[0056] The liquid container 1 can be made of any suitable material, and in embodiments for holding pesticides, the liquid container 1 can be made of a material which is resistant to corrosion, acid and alkali, sealed and light-proof, such as polyethylene, polypropylene, polyester, etc. The liquid container 1 can be made of the above-mentioned materials by processes such as blow molding or injection molding. The above description of materials and processes is merely exemplary and the solutions of the present application are not limited thereto.

[0057] ​The side wall 12 and the bottom wall 14 can be integrally formed, for example, in a one-time integral forming process such as blow molding or injection molding, thereby improving the sealing effect of the liquid container 1.

[0058] The top cover 20 can include an outer surface 21 and an inner surface 22, the outer surface 21 being a surface of the top cover 20 facing the external environment and exposed to the outside, and the inner surface 22 being opposite to the outer surface 21 and facing the internal space 2 of the liquid container 1, the inner surface 22 of the top cover 20 not being visible or clearly visible from the outside in a normal state. In the case where the top cover 20 is coupled to the container body 10 to form a closed container, the liquid container 1 can be formed with an opening 24 through which the liquid enters or exits the liquid container 1 for the convenience of liquid storage and pouring. The opening 24 can be provided on the top cover 20 as shown in the drawings, or can be provided at other positions of the liquid container 1, for example, on the side wall 12. The number of openings 24 can be one or more, and in the illustrated embodiment, two openings 24 are provided on the top cover 20. It will be understood by those skilled in the art that the number of openings 24 can be determined according to actual application requirements, which is not limited in the present application.

[0059] The container body 10 can also include an outer surface 17 and an inner surface 18, the outer surface 17 being a surface of the container body 10 facing the external environment and exposed to the outside, and the inner surface 18 being opposite to the outer surface 17 and facing the internal space 2 of the liquid container 1, the inner surface 18 of the container body 10 not being visible or clearly visible from the outside in a normal state.

[0060] The liquid container 1 can also include a label 30, according to the embodiments of the present application, the label 30 can be provided on the inner surface 22 of the top cover 20 or on the inner surface 18 near the upper joint 16 of the container body 10, so that the label 30 faces the internal space 2. As Figure 2 and Figure 3 As shown, the label 30 is shown on the inner surface 22 of the top cover 20. In normal operating conditions, for example, in the liquid container 1 at rest or storage state, the liquid container 1 is usually placed vertically, and the liquid container 1 is usually not filled with liquid, so that there is a certain distance and space between the top cover 20 and the liquid surface, that is, the liquid is usually not in contact with the top cover 20. In this way, when the label 30 is on the inner surface 22 of the top cover 20, the liquid usually does not contact the label 30, so the liquid in the liquid container 1 has less effect on the label 30, and the information stored on the label 30 can be read normally even if the label 30 is inside the liquid container 1. In some specific cases, for example, during transportation, the liquid may

[0061] In some embodiments, the label 30 can also be disposed on the inner surface 18 near the upper junction 16 of the container body 10, such that the label 30 is above the liquid level of the liquid and not in contact with the liquid. Thus, similarly, the liquid in the liquid container 1 has less effect on the label 30, and the information stored on the label 30 can be read normally even if the label 30 is inside the liquid container 1. In some specific cases, for example, during transportation, the liquid can slosh or shake due to various factors, and then can contact the label 30, but after the liquid container 1 returns to the normal state, the liquid will be away from the label 30, and thus the information stored on the label 30 can be read normally.

[0062] By disposing the label 30 inside the liquid container 1, the risk of being torn off and stolen can be avoided. By disposing the label 30 on the inner surface 22 of the top cover 20 or on the inner surface 18 near the upper junction 16 of the container body 10, the effect of the liquid in the liquid container 1 on the label 30 can be avoided or reduced, so that the label can operate normally.

[0063] According to some embodiments of the present application, the container body 10 and the top cover 20 can be integrally formed.

[0064] Similar to the side wall 12 and the bottom wall 14, the container body 10 and the top cover 20 can be integrally formed, for example, formed integrally in one time in a process such as blow molding or injection molding, thereby improving the sealing effect of the liquid container 1. Specifically, the top cover 20 can be integrally formed with the side wall 12 of the container body 10 at the upper junction 16.

[0065] The integrally formed container body 10 and top cover 20 can prevent the top cover 20 from being directly removed from the container body 10 to expose the label 30, thereby further strengthening the risk of preventing the label 30 from being torn off and stolen.

[0066] According to some embodiments of the present application, the label 30 can be a radio frequency identification label.

[0067] Radio frequency identification tags are a key component of radio frequency identification (RFID) technology, and are used to communicate with a reader in a non-contact manner to achieve the purpose of identifying a target. Radio frequency identification tags and readers communicate with each other in a non-contact, two-way data communication manner through radio frequency. The reader sends a radio frequency signal, which is received by the tag and responded to by changing the internal circuit state of the tag, so as to return a radio frequency signal containing tag information. The reader receives and decodes these signals to achieve identification and data exchange of the article represented by the tag. As a core component of radio frequency identification technology, radio frequency identification tags provide an efficient and convenient solution for the identification, tracking and management of articles.

[0068] In the case where the tag 30 is arranged inside the liquid container 1, a radio frequency identification tag can be advantageously used so that a user can directly read the information stored by the tag 30 through a reader outside the liquid container 1. In this way, the tag 30 can be prevented from being torn off or stolen, and the information of the tag 30 can be read conveniently and quickly.

[0069] According to some embodiments of the present application, the tag 30 can be arranged at a central region of the inner surface 22 of the top cover 20, and away from the opening 24 of the liquid container 1.

[0070] As shown, in the case where the liquid container 1 has a large volume, the opening 24 can be arranged, for example, at the edge of the top cover 20 to facilitate the liquid to enter and exit the liquid container 1. In this case, the tag 30 can be arranged at a substantially central region of the inner surface 22 of the top cover 20, so that the tag 30 is away from the opening 24 of the liquid container 1, preventing the tag 30 inside the liquid container 1 from being easily accessed through the opening 24.

[0071] According to some embodiments of the present application, the tag 30 can be attached to the top cover 20 or the container body 10. Typically, the tag 30 can be in the form of a sheet, which can be attached to the inner surface of the liquid container 1 using, for example, an adhesive or other bonding means, and is simple and convenient to install.

[0072] According to some embodiments of the present application, the liquid container 1 can be provided with a positioning structure configured to hold and secure the tag 30.

[0073] In order to prevent the tag 30 from falling off the inner surface 22 of, for example, the top cover 20 and falling into the liquid contained in the liquid container 1, a positioning structure can be provided on the liquid container 1 to hold and secure the tag 30. The positioning structure can be any suitable positioning structure in the art, such as an elastic clip or the like. The positioning structure can hold the tag 30 attached to the inner surface of the liquid container 1, preventing it from falling off and avoiding the risk of the tag 30 falling into the liquid and becoming inoperable.

[0074] According to some embodiments of the present application, the liquid container 1 can be provided with a positioning groove 40 in which the label 30 can be embedded.

[0075] As Figure 2 and Figure 3 shown, Figure 3 is Figure 2 an enlarged view of a portion of the liquid container 1 as shown. At the position where the label 30 is located, a positioning groove 40 can be provided in which the label 30 is embedded. In the illustrated embodiment, the positioning groove 40 is provided on the inner surface 22 of the top cover 20, and correspondingly, the label 30 is also provided on the inner surface 22 of the top cover 20, in the positioning groove 40. In another embodiment, in the case where the label 30 is provided on the inner surface 18 of the container body 10 near the upper joint 16 of the container body 10, the positioning groove 40 can be correspondingly provided on the inner surface 18 of the container body 10.

[0076] The positioning groove 40 can be a groove formed by being recessed with respect to the inner surface 22 of the top cover 20 or the inner surface 18 of the side wall 12. The shape of the positioning groove 40 can substantially correspond to the shape of the label 30, so that the label 30 is snugly embedded in the positioning groove 40. The size of the positioning groove 40 can substantially correspond to or be slightly larger than the size of the label 30, so that the label 30 can be sufficiently accommodated in the positioning groove 40. In addition, the positioning groove 40 can be provided with a structure for retaining the label 30, such as a protrusion extending inwardly from the edge of the positioning groove 40, so as to retain the label 30 in the positioning groove 40 and prevent the label 30 from falling off.

[0077] The positioning groove 40 can be directly formed on the inner surface of the top cover 20 or the container body 10 when the top cover 20 or the container body 10 is formed by, for example, blow molding or injection molding, or the positioning groove 40 can be formed by removing part of the material on the inner surface of the top cover 20 or the container body 10 after the top cover 20 and the container body 10 are formed.

[0078] According to some embodiments of the present application, the positioning groove 40 can be configured such that when the label 30 is embedded in the positioning groove 40, the label 30 is flush with or recessed into the inner surface of the liquid container 1.

[0079] In some embodiments, the depth of the positioning groove 40 may be set to be approximately equal to the thickness of the label 30, such that when the label 30 is in the positioning groove 40, the label 30 is approximately flush with the inner surface of the liquid container 1. This maintains a generally flat inner surface for the liquid container 1. In some embodiments, the depth of the positioning groove 40 may be slightly greater than the thickness of the label 30, such that when the label 30 is in the positioning groove 40, the label 30 is recessed relative to the inner surface of the liquid container 1.

[0080] The positioning groove 40 can be used to hold and fix the label 30 to prevent the label 30 from falling off. At the same time, the positioning groove 40 allows the label 30 to be flush with or recessed into the inner surface of the liquid container 1, making it more difficult to detect the label and further increasing the risk of the label 30 being torn off and stolen.

[0081] According to some embodiments of this application, a protective element 50 may be covered on the label 30, which separates the label 30 from the internal space 2.

[0082] like Figure 3 As shown, in some embodiments, a protective element 50 may be provided to protect the label 30. The protective element 50 may at least partially cover the label 30, for example, it may completely cover the label 30, in order to separate the label 30 from the internal space of the liquid container 1, and in particular, to prevent the label 30 from contacting the liquid contained in the liquid container 1. The protective element 50 may be in the form of a protective film, such as a thin film, and its size may be formed slightly larger than the size of the label 30 so as to preferably completely cover the label 30. In some embodiments, the size of the protective element 50 may be slightly larger than the cross-section of the positioning groove 40, such that when the label 30 is embedded in the positioning groove 40, the protective element 50 can adhere to the periphery of the positioning groove 40 to cover the label 30 in the positioning groove 40, thereby protecting the label 30 from the liquid contained in the liquid container 1.

[0083] The protective element 50 can be made of a suitable material, such as a material that has a large surface tension difference with the liquid to be contained in the liquid container 1, so that the liquid is difficult to adhere to the surface of the protective element 50, thereby minimizing the impact of the liquid on the label 30.

[0084] According to some embodiments of this application, the liquid container 1 is provided with a shielding member 60, which is disposed on the outer surface of the liquid container 1 at a position corresponding to the label 30.

[0085] like Figure 4 As shown, Figure 4A perspective view of the liquid container 1 according to some embodiments of the present application is shown. When the liquid container 1 is made as a transparent or translucent container, for example in the case where the liquid container 1 is made of a transparent or translucent material, it can be possible to see the label 30 from the outside of the container through the top cover or side wall of the container, resulting in an increased risk of the label 30 being torn off or stolen. At this time, a shielding member 60 can be provided on the outer surface of the liquid container 1 at a position corresponding to the label 30, so that the shielding member 60 can cover the label 30. The shielding member 60 can be provided, for example, as a nameplate or information display column conventionally provided on the container, and mark conventional information such as the size of the container, matters to be noted, and the like, to serve as a certain decoy.

[0086] According to some embodiments of the present application, the diameter of the top cover 20 can be greater than or equal to 500 mm, and / or the volume of the liquid container 1 can be greater than or equal to 150 liters.

[0087] The liquid container 1 according to the present application can be designed to have any suitable size as needed, but a large size container is more advantageous for holding a chemical such as a pesticide or herbicide. In some embodiments, for example in the case where the liquid container 1 is a cylindrical structure and the top cover 20 is a circular shape, the diameter of the top cover 20 can be greater than or equal to 500 mm, for example in the range of 500 mm to 1200 mm, for example approximately 580 mm. In some embodiments, the volume of the liquid container 1 can be greater than or equal to 150 liters, for example in the range of 150 liters to 400 liters, for example approximately 200 liters.
