Description

Technical Field

[0001] The utility model relates to the technical field of article freshness preservation, in particular to an inflation element, an inflation device and an inflation system. Background Art

[0002] In order to prolong the shelf life of existing bottled items, such as medicines and food, nitrogen or other inert gases are filled into the packaging bottles to replace the air in the packaging bottles, reduce the oxygen content in the packaging bottles, and thus extend the shelf life of the items.

[0003] Existing nitrogen filling technologies include vacuum nitrogen filling and non-vacuum nitrogen filling. Among them, the vacuum nitrogen filling method is to first vacuum the sealed packaging bottle after filling, and then inject nitrogen into the packaging bottle to complete the replacement of the air in the packaging bottle. According to the different preservation requirements of different items, the number of vacuuming and nitrogen filling operations can be increased to improve the replacement rate of the air in the packaging bottle. This operation process is all carried out inside the bottle, so it has the technical effect of high airtightness and good nitrogen filling effect. However, since the vacuuming and nitrogen filling operations need to be performed multiple times, the complexity of the operation is increased, and the preservation cost is increased.

[0004] The non-vacuum nitrogen filling method involves placing a nitrogen filling needle above the bottle mouth. Nitrogen is then injected into the filled bottle through the nitrogen filling needle. The bottle is then transported to the capping (corking) station for capping (corking). This nitrogen filling method is simple to operate and eliminates the need for multiple nitrogen filling operations, making it widely used due to its low cost. However, during the period between nitrogen filling and capping (corking), there is a possibility of nitrogen escaping from the bottle and air entering. Furthermore, the internal space of the cap (corking) can also introduce air into the bottle, increasing the amount of air inside the bottle and reducing the amount of nitrogen inside, resulting in a decrease in the bottle's freshness preservation effect. Utility Model Content

[0005] In view of this, the utility model provides an inflation element, an inflation device and an inflation system to solve the problem that the existing non-vacuum nitrogen filling preservation method is prone to nitrogen leakage and air entry in the packaging bottle during the period from the completion of nitrogen filling to the completion of capping (stoppering) of the packaging bottle, resulting in a reduction in the preservation effect of the items in the packaging bottle.

[0006] In a first aspect, the present invention provides an inflation element for filling an inert gas into a container, wherein the container comprises a body and a cover that are detachably connected;

[0007] The inflatable element is provided between the main body and the cover, and the inflatable element comprises:

[0008] A first surface is provided on a side of the inflatable element close to the body;

[0009] a second surface, provided on a side of the inflatable element close to the cover, wherein both the first surface and the second surface are provided with an inflatable channel;

[0010] Inflatable holes, provided on the first surface and the second surface, the inflatable holes being connected to a gas source through the inflatable channel, the gas source being used to provide the inert gas;

[0011] The first surface is arranged in contact with the container opening of the main body, and the size of the first surface is not smaller than the size of the container opening of the main body; the second surface is arranged in contact with the cover opening of the cover body, and the size of the second surface is not smaller than the size of the cover opening of the cover body.

[0012] Beneficial Effects: By locating the inflatable element between the container body and the container lid, the inflatable element can simultaneously replace the air in both the container body and the container lid with an inert gas. This prevents air from escaping into the container when the lid is connected to the body, reducing residual air within the container and thereby improving the freshness of the contents. Furthermore, by defining the relationship between the dimensions of the first surface and the container opening of the body, and the dimensions of the second surface and the lid opening, not only can air be prevented from directly entering the container through the gap between the first surface and the container opening of the body and the gap between the second surface and the lid opening when the lid is connected, but it can also prevent the air in the body and the air in the lid from mutually replacing each other, which could affect the flow direction of the airflow during the replacement of the inert gas in the body and the lid, leading to blowby and turbulence. The inflatable element in this embodiment allows the air in both the body and the lid to flow to the outside environment through the guidance of the inflatable element, thereby achieving the technical effect of improving the stability of the replacement between the inert gas and air.

[0013] In an optional embodiment, the inflatable element comprises:

[0014] an inflatable portion, wherein the inflatable hole is provided on the inflatable portion, the inflatable portion is configured to be flat, and the first surface and the second surface are both provided on the inflatable portion;

[0015] And / or, the inflatable element includes an inflatable portion, the inflatable portion is provided with the inflatable hole, and the inflatable hole is provided at the center of the inflatable portion.

[0016] Beneficial effects: By setting the inflatable portion to a flat shape, the first surface and the second surface are both set to a flat shape, which facilitates the adjustment of the size of the inflatable portion. For example, the inflatable portion can be thinned to reduce the contact distance between the inflatable portion and the main body and the cover. When the inflatable element is removed, due to the small thickness of the inflatable portion, only a small amount of negligible air enters the main body and the cover, thereby achieving the technical effect of improving the freshness of the items in the container. At the same time, when the inflation hole is located in the center of the inflatable portion, the uniformity of the size of the inflatable portion around the inflation hole can be improved, ensuring that the inflatable element can be suitable for containers of different sizes. Avoid the inflation hole being located at the edge of the inflatable portion, resulting in the inability of the inflatable portion to cover the main body and the cover, affecting the air flow and the flow direction of the nitrogen gas. The position of the inflation hole in the utility model can improve the replacement rate of nitrogen and air, thereby achieving the technical effect of improving the freshness of the items in the container.

By setting a second driving unit, the second driving unit is used to drive the inflatable element to move in a second direction through the first driving unit, and the position of the inflatable element along the second direction can be adjusted according to the size and shape of the container to be inflated. At the same time, by setting a third driving unit, the inflatable element can be driven to move in a third direction, so as to further achieve the technical effect of improving the adaptability of the inflatable element according to containers of different sizes and shapes.

[0032] In an optional embodiment, the second driving unit includes:

[0033] a first fixing element, arranged along the second direction;

[0067] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0068] The following combination Figures 1 to 7 , describing the embodiments of the present utility model.

[0069] According to an embodiment of the present invention, on the one hand, an inflatable element is provided for filling an inert gas into a container 1, wherein the container 1 includes a body 101 and a cover 102 that are detachably connected; an inflatable element 2 is disposed between the body 101 and the cover 102, and the inflatable element 2 includes:

[0070] The first surface 202 is provided on a side of the inflatable element 2 close to the body 101;

[0071] The second surface 203 is provided on a side of the inflatable element 2 close to the cover 102 . Both the first surface 202 and the second surface 203 are provided with an inflation channel.

[0072] The gas filling hole 201 is provided on the first surface 202 and the second surface 203. The gas filling hole 201 is connected to a gas source through a gas filling channel. The gas source is used to provide an inert gas.

[0073] The first surface 202 is arranged in contact with the container opening of the main body 101, and the size of the first surface 202 is not less than the size of the container opening of the main body 101. The second surface 203 is arranged in contact with the cover opening of the cover body 102, and the size of the second surface 203 is not less than the size of the cover opening of the cover body 102.

[0074] In this embodiment, the gas element 2 is used to fill the container 1 with an inert gas—a gas that does not affect the freshness of the contents. Positioning the gas element 2 between the container 1's main body 101 and its lid 102 allows the gas element 2 to simultaneously replace the air within both the container 1's main body 101 and lid 102 with the inert gas. This prevents air from escaping from the lid 102 into the main body 101 when the lid 102 is connected to the main body 101, thereby reducing residual air within the container 1 and improving the freshness of the contents. At the same time, by limiting the relationship between the first surface 202 and the container opening size of the body 101, and the relationship between the second surface 203 and the cover opening size of the lid 102, not only can the situation where air directly enters the container 1 through the gap between the first surface 202 and the container opening of the body 101 and the gap between the second surface 203 and the cover opening of the lid 102 when the lid 102 is connected to the body 101 be avoided, but also the situation where the air in the body 101 and the air in the lid 102 are replaced with each other can be avoided, which affects the flow direction of the air flow when the inert gas in the body 101 and the cover 102 are replaced with air, resulting in gas leakage and turbulence. The inflatable element 2 in this embodiment allows the air in the body 101 and the air in the lid 102 to flow to the external environment through the guidance of the inflatable element 2, thereby achieving the technical effect of improving the stability of the replacement between the inert gas and the air.

[0075] In this embodiment, the gas filled into the container 1 is an inert gas. Of course, in other embodiments, the gas filling element 2 can also be used to fill the container 1 with a non-inert gas, that is, to achieve freshness preservation in the container. This can be adjusted according to actual needs and is not limited here.

[0076] Furthermore, the "contact setting" in "the first surface 202 is in contact with the container opening of the main body 101" and "the second surface 203 is in contact with the cover opening of the cover body 102" can be understood as: natural contact, that is, the first surface 202 and the container opening of the main body 101 and the second surface 203 and the cover opening of the cover body 102 are in a fitted but non-sealed state, so that there can be an air flow space of no more than 1 mm between the first surface 202 and the container opening of the main body 101 and between the second surface 203 and the cover opening of the cover body 102, so that the air in the main body 101 and the cover body 102 can flow out, thereby realizing the replacement of inert gas and air.

[0077] Of course, in other embodiments, the size of the air flow space between the first surface 202 and the container opening of the body 101 and between the second surface 203 and the cover opening of the cover 102 can be adjusted according to actual needs, and the adjustment is not limited to no more than 1 mm.

[0078] In addition, in this embodiment, combined with Figure 5 As shown, the inflation hole 201 is designed as a circular hole. Of course, in other embodiments, the shape of the inflation hole 201 can be adjusted according to the design of the inflation element 2 and actual needs. For example, the inflation hole 201 can be square.

[0079] In addition, in this embodiment, nitrogen is selected as the inert gas, that is, the gas source is a nitrogen source. Of course, in other embodiments, other inert gases can be selected as needed to achieve the same technical effect of preserving the objects in the container 1, such as food or medicine.

[0080] In addition, combined Figure 1 and Figure 3 As shown, there are multiple, for example, four, gas filling elements 2. Based on this, multiple containers 1 can be filled with nitrogen at the same time, which can achieve the technical effect of improving the gas filling efficiency of the containers 1.

[0081] In addition, combined Figure 5 As shown, the inflatable element 2 includes:

[0082] The inflatable portion is provided with an inflatable hole 201. Both the first surface 202 and the second surface 203 are provided on the inflatable portion, and the inflatable portion is designed to be flat. Therefore, by providing both the first surface 202 and the second surface 203 of the inflatable portion with a flat shape, the size of the inflatable portion can be easily adjusted. For example, the inflatable portion can be thinned to reduce the contact distance between the inflatable portion and the body 101 and the cover 102. When the inflatable element 2 is removed, due to the small thickness of the inflatable portion, only a small and negligible amount of air enters the body 101 and the cover 102, thereby achieving the technical effect of improving the freshness of the items in the container 1.

[0083] Preferably, the thickness of the inflatable portion, i.e. Figure 6 Of course, in other embodiments, the thickness of the inflatable portion can be adjusted according to the design of the inflatable element 2, and the thickness is not limited to being no greater than 3 mm.

[0084] Further, combined with Figure 5As shown, the air filling hole 201 is located at the center of the air filling portion. Based on this, the air filling area around the air filling hole 201 is uniform, so as to ensure that the air filling portion can be applied to containers 1 of different sizes, and to avoid the air filling hole 201 being located at the edge, which causes the air filling portion to be unable to cover the main body 101 and the cover 102, affecting the air flow direction of air and nitrogen. The position of the air filling hole 201 in this embodiment can improve the replacement rate of nitrogen and air, thereby achieving the technical effect of improving the freshness of the items in the container 1. As a convertible embodiment, the air filling hole 201 can also be located at the edge of the air filling portion, but in actual operation, it should be noted that the air filling hole 201 is arranged relative to the main body 101 and the cover 102.

[0085] Specifically, combined Figure 7 As shown, nitrogen enters the body 101 from the center through the inflation hole 201 of the inflation element 2. Under the pressure of the nitrogen flow, the air in the body 101 flows out of the body 101 around the nitrogen flow, thus replacing the nitrogen with the air in the body 101. Similarly, nitrogen enters the cover 102 from the center through the inflation hole 201 of the inflation element 2. Under the pressure of the nitrogen flow, the air in the cover 102 flows out of the cover 102 around the nitrogen flow, thus replacing the nitrogen with the air in the cover 102.

[0086] Of course, in other embodiments, depending on the structure and actual usage of the inflatable element 2 , the inflatable element 2 may be simply flat, or the inflation hole 201 may be simply located at the center of the inflatable element 2 .

[0087] In addition, combined Figure 5 and Figure 6 As shown, in this embodiment, the inflatable element 2 includes:

[0088] A first shell having a first surface 202 formed thereon and a first hollow structure provided on the first shell;

[0089] The second shell has a second surface 203 formed thereon. The second shell is aligned with the first shell. Figure 6 The vertical split is fixedly connected, and the second shell is provided with a second hollow structure, and the second hollow structure and the first hollow structure are together formed into an inflation channel. Figure 6 The vertical length shown is 1 mm, so that nitrogen can enter the body 101 and the cover 102 through the inflation channel. As a convertible embodiment, the inflation channel can also be Figure 6 Adjust the length in the vertical direction as shown.

[0090] The first shell and the second shell can be fixed around by welding. As a changeable embodiment, the first shell and the second shell can be connected and fixed by gluing or other methods.

[0091] Of course, in other embodiments, the inflatable element 2 can be directly configured as a flat structure and the inflatable channel can be processed later. Compared to other embodiments, this embodiment provides a split structure for the inflatable element 2, with the inflatable channel formed by the first hollow structure of the first shell and the second hollow structure of the second shell. This eliminates the need for an additional inflatable channel, thereby improving the ease of processing of the inflatable element 2.

[0092] Combine Figure 5 and Figure 6 As shown, the inflatable element 2 in this embodiment includes a fixing portion, which is fixedly connected between the inflatable element and the gas source and is used to fix the position of the inflatable element 2. The fixing portion is cylindrical and Figure 6 As shown, along the vertical direction, the size of the fixed portion is larger than that of the inflatable portion, and an inflation channel is provided on the fixed portion to facilitate the flow of gas from the gas source to the inflatable element 2.

[0093] Based on this, in this embodiment, the first shell and the second shell have the same structure, including:

[0094] The fixed part is a semi-cylindrical structure;

[0095] The inflatable part is connected and fixed to the fixing part, and the inflatable hole 201 is provided on the inflatable part;

[0096] The connecting part is connected between the fixing part and the inflatable part. The cross section of the connecting part is as follows: Figure 6 The trapezoidal shape is shown to achieve the size transition between the inflatable part and the fixed part.

[0097] Based on this, when nitrogen passes through the connecting portion, due to the trapezoidal cross-section of the connecting portion, the flow area becomes smaller during the nitrogen flow process, causing the nitrogen to be squeezed, which can increase the flow rate of nitrogen in the connecting portion. Furthermore, because the inflatable portion is a hollow structure, that is, the size of the inflatable channel inside the inflatable portion is larger than the size of the inflatable hole 201. When nitrogen passes through the connection between the inflatable channel in the inflatable portion and the inflatable hole 201, and due to the size difference between the inflatable channel and the inflatable hole 201, the nitrogen can be squeezed, further increasing the flow rate of nitrogen, enhancing the impact force of nitrogen and the squeezing force on the air, thereby achieving the technical effect of increasing the replacement rate of nitrogen and air.

[0098] According to an embodiment of the present invention, on the other hand, an inflation device is provided, comprising the inflation element 2 described above.

[0099] In addition, combined Figures 1 to 4 As shown, the inflatable device further includes a flow adjustment structure 3, one end of which is connected to the gas source and the other end of which is connected to the fixed portion of the inflatable element 2. The flow adjustment structure 3 can be used to adjust the flow rate and flow of the gas source as needed. As an alternative embodiment, the inflatable device can also not include the flow adjustment structure 3.

[0100] Specifically, the flow adjustment structure 3 includes:

[0101] The regulating element 301 is connected to the gas source;

[0102] One end of the pipe 302 is connected to the regulating element 301 , and the other end is connected to the inflatable element 2 .

[0103] The regulating element 301 is a solenoid valve that can improve the accuracy of nitrogen flow adjustment. Meanwhile, the pipe 302 is a flexible tube that allows its position to be adjusted as the inflatable element 2 is adjusted without separating from the inflatable element 2, thus ensuring the stability of the connection between the pipe 302 and the inflatable element 2.

[0104] As a convertible method, the regulating element 301 can also be a common flow regulating valve, and the pipeline 302 can be a telescopic tube, which will not be described in detail here.

[0105] In addition, combined Figures 1 to 4 As shown, in this embodiment, the inflation device further includes:

[0106] The position adjustment structure is provided on one side of the container 1 and is connected to the inflatable element 2 for adjusting the position of the inflatable element 2. Based on this, the position adjustment structure can be used to adjust the position of the inflatable element 2 as needed, so that the inflatable element 2 can be used to inflate nitrogen into containers 1 of different heights and shapes.

[0107] Specifically, combined Figure 1 As shown, the position adjustment structure includes:

[0108] The first driving unit is connected to the inflatable element 2 and is used to drive the inflatable element 2 to move in a first direction. The first direction is parallel to the extension direction of the inflatable channel. That is, the first direction is Figure 1 The X-axis direction is shown.

[0109] By providing a first drive unit, the inflatable element 2 can be driven to be arranged parallel to the extension direction of the inflation channel, that is, the position of the inflatable element 2 along the X-axis direction can be adjusted. Based on this, in actual use, the inflatable element 2 can be first driven to a position away from the container 1 by the first drive unit so as not to affect the placement of the container 1. After the container 1 is placed, the inflatable element 2 can be driven to the position between the main body 101 and the cover 102 of the container 1 by the first drive unit to inflate the container 1. At the same time, the position of the inflatable element 2 along the X-axis direction can be adaptively adjusted according to the different sizes and positions of the main body 101 and the cover 102 of different containers 1 along the X-axis direction.

[0110] Further, combined with Figures 1 to 4 As shown, the first driving unit includes:

[0111] The driving element 401 has a length along the X-axis direction, and the driving element 401 can be extended or shortened along the X-axis direction. In this embodiment, the driving element 401 can be a cylinder.

[0112] Furthermore, the position adjustment structure includes:

[0113] The third fixing element 406 is connected to the output end of the first driving unit. A plurality of fixing positions are provided on the side surface of the third fixing element 406, and the inflatable element 2 is fixedly connected at the fixing positions.

[0114] The third fixing element 406 can be a connecting rod fixed to the telescopic portion of the driving element 401. The fixing position can be a fixing hole, through which the fixing portion of the inflatable element 2 passes to achieve a fixed connection between the inflatable element 2 and the third fixing element 406. As an alternative embodiment, the fixing position can also be a fixing clip, which can also achieve fixation of the inflatable element 2. As an alternative embodiment, the third fixing element 406 can be a connecting plate.

[0115] By providing a third fixing element 406 and placing the inflatable element 2 on the third fixing element 406, when the driving element 401 drives the third fixing element 406 to move, it can drive multiple inflatable elements 2 to move at the same time, thereby improving the consistency of the movement of the inflatable elements 2 and the simplicity of driving the multiple inflatable elements 2 to move, and can realize the operation of inflating multiple containers 1 with nitrogen at the same time.

[0116] Specifically, the top surface of the third fixing element 406 is provided with a positioning threaded hole, and is connected to the fixed position. It is threadedly connected to the positioning threaded hole through a top screw 407, so that the top screw 407 can apply pressure to the fixed part of the inflatable element 2, and can press the inflatable element 2 tightly to achieve the fixation of the position of the inflatable element 2 along the Z-axis direction, thereby achieving the technical effect of improving the position stability of the inflatable element 2.

[0117] Furthermore, combined with Figure 1 and Figure 3 As shown, in this embodiment, there are two driving elements 401, which are arranged at intervals and are respectively arranged at both ends of the third fixed element 406.
