Description

Technical Field

[0001] This utility model belongs to the field of sealed container technology, and in particular relates to a sealed container. Background Technology

[0002] Traditional non-vacuum sealed containers require one hand to hold the lid and the other to hold the container body, then separating the lid from the container to open it. This mandatory two-handed operation creates an obstacle when the user can only open the container with one hand, contradicting the user experience of convenient opening of the sealed container. Summary of the Invention

[0003] To address the shortcomings of existing technologies, a sealed container is provided.

[0004] This utility model is achieved using the following technical solution:

[0005] A sealed container includes a container body and a plug disposed at the opening of the container body. The container body has a radially concave neck near the opening. The plug cooperates with the neck to create a normal atmospheric pressure environment or a positive pressure environment inside the container. The pressing surface of the plug and the inner wall of the neck has a protrusion. The force between the protrusion and the inner wall of the neck can limit the depth of the plug inside the container. The end of the plug away from the container body has a control element for controlling the plug to slide away from the inner wall of the neck.

[0006] When the user moves the control, the protrusion moves together with the control towards the center of the can, thereby moving the protrusion away from the inner wall of the can neck and unlocking the plug. At this point, by holding the control, the plug can be moved away from the can to remove it and open the internal space of the can.

[0007] By applying a pulling force after unlocking the stopper, the stopper is axially separated, eliminating the need for the user's hands to exert opposing forces on the sealed can, i.e., the gripping force to hold the can in place and the pulling force to pull up the stopper. This transforms the can-opening action into a smooth, one-handed action, allowing the user to open the can without any obstacles while using one hand.

[0008] Preferably, the protrusions are provided in two symmetrically arranged on the surface of the plug, and the control components are provided in two sets corresponding to the protrusions one by one, so as to facilitate the user to apply force to the control components with both thumb and forefinger at the same time, and to use the force of the control components when they are in close proximity to each other to make the plug move away from the can.

[0009] Preferably, the plug body is hollow inside, and the plug body is provided with a sliding track and a slider for use together. An elastic element is provided between the two sliders. The protrusion is provided on the end of the slider that is directly opposite the inner wall of the can neck, and the control element is provided on the end of the slider that is away from the can body.

[0010] The plug can be a cylindrical structure, an inverted frustum-shaped structure that is wider at the top and narrower at the bottom, or an inverted conical structure that is wider at the top and narrower at the bottom.

[0011] The elastic element can be a spring connected between the two sliders, or an elastic filler filling between the two sliders, or the two sliders can have the same magnetic poles.

[0012] When the control components move closer to each other, the control components drive the protrusion to slide away from the inner wall of the tank neck via the slider, thereby unlocking the protrusion from the inner wall of the tank neck and thus unlocking the plug.

[0013] Preferably, the control element includes a connecting rod portion passing through the plug body and a gripping portion located at the end of the connecting rod portion away from the can body. The gripping portion extends in a direction away from the can body and passes over the axial end face of the can body. The plug body is provided with a waist-shaped hole for the connecting rod portion to slide linearly.

[0014] The gripping part transmits force through the connecting rod to pass through the surface of the plug and act on the slider located inside the plug. This allows the gripping part to drive the slider to move along the limiting trajectory of the slide rail, and the connecting rod to move within the waist-shaped hole.

[0015] Preferably, the inner wall of the neck of the can is provided with a groove facing the protrusion, and when the two gripping parts are in the extreme position of being far apart from each other, the protrusion extends into the groove.

[0016] The groove can be a blind hole set on the inner wall, or it can be a ring-shaped structure protruding outward. When the protrusion is embedded in the groove, the inner wall of the groove constrains the protrusion, thereby limiting the overall structure of the plug.

[0017] Preferably, the end of the protrusion facing the inner wall of the can neck is a beveled part. When the beveled part of the protrusion enters the can neck, the force exerted on the beveled part of the protrusion can bring the sliders on both sides closer to each other.

[0018] By setting the end faces of the two protrusions as bevels, when the user inserts the plug into the neck of the can, the reaction force of the groove on the protrusions when the two protrusions abut against the opening edge of the groove can cause the two protrusions to move in a direction that brings them closer together. This achieves the positioning of the protrusions and the groove in an adaptive manner, eliminating the need for the user to hold the gripping part during the insertion process to pre-adapt the spacing of the two protrusions to the spacing of the groove on both sides, making it easier for the user to install the plug.

[0019] Due to the design of the inclined surface, after the protrusion enters the groove, it can abut against the inner wall of the groove through its own circumferential side. When the plug is subjected to a force in the direction away from the tank, such as an increase in pressure inside the tank, the protrusion has no separation point, so the sliders on both sides cannot move, thus preventing the plug from unlocking and achieving one-way limiting of the plug.

[0020] Preferably, the two ends of the gripping part extend in the width direction perpendicular to the sliding direction of the slider, so that the gripping part has a pressure plate structure, which facilitates the application of force to the control component.

[0021] Preferably, the ends of the gripping parts that are far apart are provided with anti-slip texture, which further facilitates the application of force to the control components.

[0022] Preferably, a first sealing element is fitted around the end of the plug that enters the neck of the tank, thereby ensuring a sealing effect on the internal space of the tank after the plug is assembled.

[0023] Preferably, the tank includes a container section and a straight cylindrical section threadedly connected to the opening of the container section. The inner side of the straight cylindrical section is provided with a lip section extending toward the axis and toward the opening of the container section. The first sealing member cooperates with the lip section. The opening of the container section is inserted into the gap formed between the straight cylindrical section and the lip section. A second sealing member is provided in the gap.

[0024] The threaded connection between the cylindrical section and the container section facilitates the use of the sealing plug with existing tanks, replacing the original sealing cap on the tank. The tank can be any existing container whose diameter matches the plug diameter, thus expanding the applicability of this structure. The separate design of the cylindrical section and the container section facilitates the maintenance and replacement of the slots, sliders, slides, and control components, thereby reducing maintenance difficulty.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] The symmetrically arranged double gripping parts allow the stopper to be released from the axial lock of the groove on the inner wall of the neck by pinching. Then, by continuously pulling the gripping parts with one hand, the stopper can be lifted out of the can, allowing the user to open the sealed can without any obstacles with one hand, thus improving the convenience of use.

[0033] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0034] like Figure 1-5 As shown, this embodiment discloses a sealed container, including a container body 2 and a plug 1 disposed at the opening of the container body 2. The container body 2 includes a container portion 20 and a straight cylindrical portion 21 threadedly connected to the opening of the container portion 20. The inner side of the straight cylindrical portion 21 is provided with a lip portion 22 extending towards the axis and towards the opening of the container portion 20. The lip portion 22 extends downward in a waterfall-like structure. The straight cylindrical portion 21, the lip portion 22, and the opening of the container portion 20 together form the neck of the sealed container. The upper opening of the container portion 20 is inserted into the gap formed between the straight cylindrical portion 21 and the lip portion 22. A second sealing element 23 is provided in the gap. The second sealing element 23 is an O-ring, thereby enabling the plug 1 to be assembled with a container body 2 of any diameter.

[0035] The outer circular surface of the container section 20 is provided with a flat portion 3, which facilitates the two sealed containers to fit tightly together; the flat portion 3 allows the container section 20 to be placed or used in a flat manner.

[0036] The plug body 1 has a hollow shell structure. The plug body 1 includes an upper cover 10 and a base 11 that are interlocked. The interlocking method between the upper cover 10 and the base 11 is the same as that of the prior art. A first sealing element 16 is embedded on the outer circular surface of the base 11. The first sealing element 16 is an annular rubber gasket. The first sealing element 16 cooperates with the lip part 22 to make the inside of the tank body 2 a normal gas pressure environment or a positive pressure environment.

[0037] The upper cover 10 has two sliders 12 that can slide relative to each other. The two sliders 12 have a protrusion 13 at one end away from each other. The protrusion 13 has a columnar structure and its cross-sectional area is smaller than that of the slider 12. The upper cover 10 has lateral limiting plates 102 on both sides of the sliding direction of the slider 12. The lateral limiting plates 102 on both sides form a slide that can restrict the sliding path of the slider 12. The circumferential sidewall of the base 11 has a notch 111 that fits into the lateral limiting plates 102 on both sides.

[0038] The two protrusions 13 are used to abut against the inner wall of the can neck. One end of the protrusion 13 is a beveled part 131. The two beveled parts 131 are inclined from top to bottom towards the axis. When the beveled part 131 of the protrusion 13 enters the can neck, the force on the beveled part 131 of the protrusion 13 can make the sliders 12 on both sides move closer to each other.

[0039] The straight cylindrical part 21 is provided with a groove 211 facing the protrusion 13 on the upper side of the lip part 22. The groove 211 is a ring-shaped structure with an outward protruding enclosing hole. When the protrusion 13 is embedded in the groove 211, the inner wall of the groove 211 constrains the protrusion 13, thereby limiting the overall structure of the plug body 1. When the two protrusions 13 on both sides abut against the groove 211, the reaction force of the groove 211 on the inclined part 131 causes the two sliders 12 on both sides to move closer to each other, so that the two protrusions 13 on both sides enter the groove 211 at an adaptive distance.

[0040] Both sliders 12 are equipped with control components 14 at their upper ends. Each control component 14 includes a connecting rod portion 142 passing through the plug body 1 and a gripping portion 141 located at the end of the connecting rod portion 142 away from the can body 2. The gripping portion 141 extends at both ends in the width direction perpendicular to the sliding direction of the sliders 12, thus giving the gripping portion 141 a pressure plate structure. The ends of the gripping portions 141 that are far apart from each other serve as contact surfaces for the user to pinch. Figure 5 As shown, the contact end surface of the gripping part 141 is provided with anti-slip texture 1411, and the upper end of the gripping part 141 extends away from the can body 2 and is higher than the upper surface of the cover 10, thereby making it easier for the user to grip the control parts 14 on both sides.

[0041] The upper cover 10 is provided with a waist-shaped hole 101 for the connecting rod part 142 to slide linearly, so that the sliders 12 on both sides slide in a direction that approaches each other; the lower end face of the gripping part 141 is provided with a protrusion 1412, which can reduce the contact area between the gripping part 141 and the upper cover 10 during movement, thereby reducing friction; when the gripping parts 141 on both sides are at the extreme position of being far apart from each other, the protrusion 13 extends into the groove 211.

[0042] An elastic element 15 is provided between the two sliders 12. The elastic element 15 is a thrust spring, which allows the two sliders 12 to reset autonomously by utilizing the elastic deformation of the thrust spring.

[0043] In the sealed state, the plug 1 is located on the tank 2 and the first seal 16 is pressed against the lip 22, the two sliders 12 are located in a position far apart from each other, and the protrusion 13 is located in the groove 211.
