Description

Technical Field

[0001] This utility model relates to, but is not limited to, the field of container packaging technology, and in particular to a liquid press container with a clearance section. Background Technology

[0002] Liquid pump bottles are essential household items, widely used for holding liquids such as shower gel, body lotion, and detergents, allowing liquid to be dispensed using a pump. However, when users carry liquid pump bottles outdoors, especially during air transport, the product is exposed to extreme pressure changes. This can cause viscous liquid stored inside the bottle to accidentally seep into the pump body through the vent. Once inside, this viscous liquid accumulates in the venting channel, clogging it or significantly reducing its efficiency. This not only affects normal product use and reduces pumping smoothness, but can also cause the container to deform due to internal pressure imbalance, resulting in a flattened bottle, or even pump head malfunction, preventing proper liquid dispensing.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other. The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0029] like Figure 1 As shown, Figure 1 This is a front sectional view of a liquid press container with a clearance portion 211 provided in one embodiment of the present invention. The liquid press container includes a bottle body 100, a pump head 200, and a locking member 300. At least one clearance portion 211 is provided between the main column 210 of the pump head 200 extending into the bottle body 100 and the locking member 300. The clearance portion 211 is used to form a first gap between the outer side of the main column 210 and the inner side of the locking member 300. Figure 1 The diagram shows that the clearance part 211 is installed on the main column 210.

[0030] It should be noted that, in this embodiment of the liquid press container, at least one clearance portion 211 is provided between the main column 210 and the locking member 300, forming a first gap between the outer surface of the main column 210 and the inner surface of the locking member 300. This effectively increases the venting channel in the liquid press container, effectively avoiding the problem of liquid accumulation in the venting channel, which could block the channel or significantly reduce its venting efficiency. This ensures that the venting channel can continuously and effectively balance the internal and external air pressure of the bottle, preventing the container from deforming due to internal pressure imbalance, improving the liquid discharge efficiency and stability, and thus enhancing the user experience. In addition, the first gap can also reduce the friction between the pump head 200 and the bottle body 100, making operation easier. Furthermore, both the bottle body 100 and the pump head 200 can be made of high-quality plastic, ensuring the durability of the container while reducing production costs.

[0031] It should also be noted that the locking fastener 300 is used to lock the pump head 200 to the bottle body 100, to prevent the pump head 200 from popping out due to loosening, or to prevent the liquid in the container from leaking out due to accidental contact, thus causing waste.

[0032] In this application embodiment, the specific shape, width and depth of the first gap are not limited, as long as it can effectively avoid the contact between the outer side of the main column 210 and the inner side of the locking member 300, and will not have too much impact on the overall structure of the container.

[0033] In one possible implementation, such as Figure 2 As shown, the clearance part 211 is provided on the outer side of the main column 210.

[0034] It should be noted that the clearance part 211 is provided on the outer side of the main column 210. This is equivalent to reducing part of the volume of the main column 210 so that the outer side of the main column 210 and the inner side of the locking member 300 form a first gap. This gap can effectively balance the internal and external air pressure of the bottle and prevent the container from deforming due to internal pressure imbalance. In this embodiment, by reducing part of the volume of the main column 210 to form the clearance part 211, the exhaust channel in the liquid press container is effectively increased. This can effectively avoid the problem of liquid accumulating in the exhaust channel, thereby blocking the channel or significantly reducing its exhaust efficiency. This ensures that the exhaust channel can continuously and effectively balance the internal and external air pressure of the bottle, prevent the container from deforming due to internal pressure imbalance, improve the liquid discharge efficiency and stability, and thus enhance the user experience.

[0035] In one possible implementation, such as Figure 2 As shown, the outer side of the main column 210 includes a first main column side 212, a main column inclined surface 213, and a second main column side 214. The first main column side 212 is connected to the second main column side 214 through the main column inclined surface 213. The diameter of the first main column side 212 is larger than the diameter of the second main column side 214. The clearance portion 211 is provided on the second main column side 214.

[0036] It should be noted that the outer surface of the main column 210 includes a first main column side 212, a main column inclined surface 213, and a second main column side 214. The first main column side 212 is connected to the second main column side 214 through the main column inclined surface 213. The diameter of the first main column side 212 is larger than the diameter of the second main column side 214 to form a first gap between the second main column side 214 and the inner surface of the locking member 300. Furthermore, by creating a first gap between the side surface 214 of the second main column and the inner surface of the locking member 300, and by providing a clearance part 211 on the side surface 214 of the second main column, the distance between the side surface 214 of the second main column and the inner surface of the locking member 300 can be effectively increased without significantly affecting the overall structure of the container. This increases the venting channel in the liquid press container, effectively avoiding the problem of liquid accumulating in the venting channel and thus blocking the channel or significantly reducing its venting efficiency. This ensures that the venting channel can continuously and effectively balance the internal and external air pressure of the bottle, preventing the container from deforming due to internal pressure imbalance, improving the liquid discharge efficiency and stability, and thus enhancing the user experience.

[0037] It should also be noted that the number of clearance parts 211 is not limited in this application embodiment; there can be one or more. When there are multiple clearance parts 211, these clearance parts 211 can be evenly distributed on the side surface 214 of the second main column. This can further improve the gas discharge efficiency and ensure that the container maintains a stable pressure during use.

[0038] In one possible implementation, the second main column side surface 214 includes a first arc surface and a first plane, the first arc surface being connected to the first plane, and the first plane forming the clearance portion 211; or, the second main column side surface 214 includes a first arc surface and a first arc surface recessed toward the central axis of the main column 210, the first arc surface being connected to the first arc surface, and the first arc surface forming the clearance portion 211.

[0039] It should be noted that the clearance portion 211 provided in this application embodiment can be configured as a first plane or as a first arc surface recessed towards the central axis of the main column 210, both of which can effectively increase the distance between the side surface 214 of the second main column and the inner side surface of the locking member 300, thereby increasing the venting channel in the liquid press container. Furthermore, it is understood that this application embodiment does not limit the shape of the clearance portion 211; the shape of the clearance portion 211 can be adjusted accordingly to accommodate the layout of multiple clearance portions 211.

[0040] In one possible implementation, the clearance portion 211 is disposed on the inner side of the locking member 300.

[0041] It should be noted that, in this invention, in addition to designing the second main post side 214 to form a first gap between the second main post side 214 and the inner side of the locking member 300, the same first gap structure can also be achieved by designing the inner side of the locking member 300. In this case, the inner side of the locking member 300 can be shaped to have a specific contour or shape, so as to create an unobstructed channel between the second main post side 214 and the inner side of the locking member 300.

[0042] In one possible implementation, the inner side of the locking member 300 includes a first inner side 310 and a second inner side 320, the first inner side 310 and the second inner side 320 are connected, and the clearance portion 211 is disposed on the first inner side 310.

[0043] In some embodiments of this utility model, the inner side of the locking member 300 includes a first inner side 310 and a second inner side 320. A clearance portion 211 is disposed on the first inner side 310, creating a first gap between the first inner side 310 and the side of the main column. This effectively increases the distance between the first inner side 310 and the side of the main column, thus increasing the venting channel in the liquid press container. This ensures that the venting channel can continuously and effectively balance the internal and external air pressure of the bottle.

[0044] In one possible implementation, such as Figure 3 As shown, the first inner surface 310 includes an inwardly recessed second arc surface, which forms the avoidance portion 211.

[0045] It should be noted that by providing an inwardly recessed second arc surface in the first inner side 310 of the locking member 300, this second arc surface forms a clearance portion 211, creating a first gap between the first inner side 310 and the side of the main column. This effectively increases the distance between the first inner side 310 and the side of the main column, thus increasing the venting channel in the liquid press container. Furthermore, it is understood that the embodiments of this application do not limit the shape of the clearance portion 211; the shape of the clearance portion 211 can be adjusted accordingly to accommodate the layout of multiple clearance portions 211.

[0046] It should also be noted that the number of clearance parts 211 is not limited in this application embodiment; there can be one or more. When there are multiple clearance parts 211, these clearance parts 211 can be evenly distributed on the inner surface of the locking member 300. This can further improve the gas discharge efficiency and ensure that the container maintains a stable pressure during use.

[0047] In one possible implementation, the pump head 200 has an exhaust port 220 on the outer wall portion extending into the bottle body 100, the exhaust port 220 facing the inner side of the main body of the bottle body 100.

[0048] In some embodiments of this utility model, the vent 220 faces the inner side of the bottle body 100, ensuring that the gas inside the bottle body 100 can be smoothly discharged when the pump head 200 is used. Furthermore, the vent 220 faces the inner side of the bottle body 100, meaning there is a large space between the vent 220 and the inner side of the bottle body 100, effectively preventing accidental blockage of the vent 220. This ensures smooth gas flow inside and outside the container, thereby improving the container's efficiency and user experience. Moreover, the embodiments of this application do not limit the size and shape of the vent 220, as long as it ensures smooth gas flow and does not cause blockage due to improper size or shape.

[0049] In one possible implementation, such as Figure 4 As shown, the outer wall portion includes a first outer wall surface 221, an outer wall inclined surface 222, and a second outer wall surface 223. The first outer wall surface 221 is connected to the second outer wall surface 223 via the outer wall inclined surface 222. The vent 220 is disposed on the second outer wall surface 223 or the outer wall inclined surface 222. Figure 4 The exhaust port 220 is shown as being located on the second outer wall surface 223.

[0050] In some embodiments of this utility model, the outer wall portion of the pump head 200 extending into the bottle body 100 includes a first outer wall surface 221, an outer wall slope 222, and a second outer wall surface 223. The first outer wall surface 221 is connected to the second outer wall surface 222 via the outer wall slope 222 and the second outer wall surface 223. The vent 220 is positioned on the second outer wall surface 223 or the outer wall slope 222. This effectively prevents the vent 220 from being blocked by liquid due to its placement on the first outer wall surface 221, which could affect gas flow and disrupt the balance of internal and external gas pressure. By positioning the vent 220 on the second outer wall surface 223 or the outer wall slope 222, the distance between the vent 220 and the bottle body 100 is increased, preventing accidental blockage and ensuring smooth gas flow between the inside and outside of the container. This improves the container's efficiency and user experience.

[0051] In one possible implementation, such as Figure 5As shown, the outer side of the locking member 300 includes a first outer side 330, a horizontal outer side 340, and a second outer side 350. The first outer side 330 is connected to the second outer side 350 through the horizontal outer side 340. The position of the second outer side 350 corresponds to the position of the vent 220. A second gap is formed between the second outer side 350 and the outer wall portion.

[0052] It should be noted that, as shown in the figure, by setting the vent 220 on the second outer wall surface 223 or the outer wall slope 222, and with the position of the vent 220 corresponding to the position of the second outer side surface 350 of the locking member 300, a second gap is formed between the second outer side surface 350 and the outer wall portion. This avoids the risk of the vent 220 being blocked by liquid due to the vent 220 abutting against the first outer side surface 330 of the locking member 300, thus affecting the flow of gas and failing to balance the gas pressure inside and outside the bottle. The position of the second outer side surface 350 corresponding to the position of the vent 220 increases the distance between the vent 220 and the second outer side surface 350, thereby preventing the vent 220 from being accidentally blocked and ensuring smooth flow of gas inside and outside the container, thus improving the container's efficiency and user experience.

[0053] It is understandable that the liquid in the liquid pump container can be shampoo, conditioner, shower gel, hand sanitizer, various cosmetic lotions, medicine, seasonings, and liquid food, etc., and no further restrictions will be imposed here.
