[0028] The utility model embodiment is further described below with reference to the drawings.

[0029] Refer to Figure 1 , Figure 1 It is the main sectional view of the liquid pressing container with exhaust hole provided in an embodiment of the utility model. The liquid pressing container includes two big components of bottle body 110 and pump head 120. Wherein, the outer wall part of pump head 120 that stretches into the inside of bottle body 110 is provided with exhaust hole 121. Specifically, exhaust hole 121 is towards the inside surface 111 of the bottle mouth surrounding wall of bottle body 110, when pump head 120 is used, it can ensure that the gas in the inside of bottle body 110 can be smoothly discharged. Further, in order to avoid unnecessary abutment of exhaust hole 121 and bottle mouth 111 in the use process, and then cause exhaust hole 121 to be accidentally blocked, a gap 122 can be arranged between exhaust hole 121 and the inside surface 111 of bottle mouth surrounding wall, the gap 122 can effectively prevent exhaust hole 121 and the inside surface 111 of bottle mouth from directly contacting, thereby ensuring that the gas in the container and outside the container can flow smoothly, and then improving the use efficiency and user experience of the container. In addition, the gap 122 can also reduce the friction between pump head 120 and bottle body 110, so that the operation is more relaxed.

[0030] In some embodiments of the utility model, such as Figure 1As shown, the inner part of the pump head 120 is provided with a locking member 130, which can be used to lock the pump head 120 and the bottle body 110, for example, when the pump head 120 is inserted into the inner part of the bottle body 110 until the front end face of the pump head 120 is tightly fitted with the front end face of the bottle mouth, the locking member 130 can be buckled on the front end face of the pump head 120 to ensure the tight connection between the pump head 120 and the bottle body 110. Further, the locking member 130 includes an inner wall 131 corresponding to the position of the outer wall part, and a gap is provided between the inner wall 131 and the outer wall part, and the exhaust hole 121 is directed to the inner wall 131. Such a layout can form an efficient gas passage, thereby effectively balancing the air pressure inside and outside the bottle.

[0031] It should be noted that the specific shape, width and depth of the gap 122 are not limited in the embodiments of the present application, as long as the abutment between the exhaust hole 121 and the bottle mouth 111 can be effectively avoided, and the overall structure of the container will not be excessively affected. In addition, the size and shape of the exhaust hole 121 are not limited in the embodiments of the present application, as long as the gas can flow smoothly, and the size or shape will not cause blockage. In addition, the materials of the bottle body 110 and the pump head 120 can be high-quality plastics, which can not only ensure the durability of the container, but also reduce the production cost.

[0032] In some embodiments of the present application, the outer wall part of the pump head 120 inserted into the inner part of the bottle body 110 is provided with an inwardly recessed air avoidance groove, thereby forming a gap 122, and the exhaust hole 121 is arranged in the air avoidance groove. Specifically, as shown in Figure 2 The outer wall part can be composed of a first outer wall face 210, an outer wall inclined face 220 and a second outer wall face 230, wherein the first outer wall face 210 is connected with the second outer wall face 230 through the outer wall inclined face 220. It is worth noting that the diameter of the first outer wall face 210 is greater than the diameter of the second outer wall face 230, so that an inwardly recessed air avoidance groove can be formed through the extension face 231 of the first outer wall face 210 and the second outer wall face 230. Specifically, the air avoidance groove is arranged on the first outer wall face 231, the bottom face of which is an extension face 231 of the second outer wall face 230, and the exhaust hole 121 can be located on the extension face 231.

[0033] In some embodiments of the present application, as shown in Figure 3 The outer wall part of the pump head 120 inserted into the inner part of the bottle body 110 includes a first outer wall face 310, an outer wall inclined face 320 and a second outer wall face 330. The first outer wall face 310 is connected with the second outer wall face 330 through the outer wall inclined face 320. In particular, the diameter of the first outer wall face 310 is greater than the diameter of the second outer wall face 330, so that the outer wall part can form a gap 122 with the inner side face 111. The exhaust hole 121 can be arranged on the second outer wall face 330 or the outer wall inclined face 320. Figure 3The exhaust hole 121 is arranged on the second outer wall surface 330.

[0034] In some embodiments of the present application, as shown in Figure 4 The outer wall portion of the pump head 120 extending into the bottle body 110 includes an inwardly recessed arc surface 410. The arc surface 410 and the inner side surface 111 form a gap 122, and the exhaust hole 121 is arranged on the arc surface 410. Further, the outer wall portion includes a first outer wall surface 420 and a second outer wall surface 430 in addition to the arc surface 410, and the first outer wall surface 420 is connected to the second outer wall surface 430 through the arc surface 410. In particular, the diameter of the first outer wall surface 420 is greater than the diameter of the second outer wall surface 430, so that an efficient gas passage is formed between the first outer wall surface 420 and the gap 122, and the exhaust hole 121 can continuously and effectively balance the air pressure inside and outside the bottle.

[0035] It should be noted that the number of exhaust holes 121 is not limited in the embodiments of the present application, and can be one or multiple. When the number of exhaust holes 121 is multiple, the exhaust holes 121 can be evenly distributed on the outer wall portion of the pump head 120. In this way, the gas exhaust efficiency can be further improved, and the pressure of the container can be kept stable during use. At the same time, the shape of the gap 122 can also be adjusted accordingly to adapt to the layout of the multiple exhaust holes 121.

[0036] It should be noted that in the present application, in addition to the design of the outer wall portion of the pump head 120 to form the gap 122 between the exhaust hole 121 and the inner side surface 111, the inner side surface 111 can also be designed to achieve the same gap 122 structure. In this case, the inner side surface 111 can be shaped to have a specific profile or shape, such as a slight outward protrusion or a specific groove, to create an unobstructed passage for the exhaust hole 121.

[0037] In some embodiments of the present application, as shown in Figure 5 The inner side surface 111 of the bottle mouth surrounding wall includes a first side surface 510, an inclined side surface 520, and a second side surface 530, and the first side surface 510 is connected to the second side surface 530 through the inclined side surface 520. It is worth noting that the distance between the first side surface 510 and the outer wall portion is less than the distance between the second side surface 530 and the outer wall portion, so that a gap 122 can be created between the inner side surface 111 and the exhaust hole 121.

[0038] In some embodiments of the present application, as shown in Figure 6As shown, the inner side surface 111 of the bottle mouth surrounding wall comprises an inwardly recessed arc surface 610, which can form a gap 122 with the outer wall portion. Further, the inner side surface 111 further comprises a first side surface 620 and a second side surface 630, wherein the first side surface 620 is connected with the arc surface 610 and the second side surface 630. In particular, the distance between the first side surface 620 and the outer wall portion is less than the distance between the second side surface 630 and the outer wall portion, so that an efficient gas passage can be formed with the gap 122, and the exhaust hole 121 can continuously and effectively balance the air pressure inside and outside the bottle.

[0039] In some embodiments of the present application, as shown in Figure 7 As shown, the inner side surface 111 of the bottle mouth surrounding wall can only comprise an inwardly recessed arc surface 710 and a first side surface 720, wherein the arc surface 710 and the first side surface 720 are connected, and in particular, the distance between the first side surface 710 and the outer wall portion is less than the distance between the arc surface 720 and the outer wall portion, so as to form the gap 122.

[0040] It can be understood that the liquid in the liquid pressing container can be shampoo, hair conditioner, shower gel, hand sanitizer, various cosmetic lotions, medicinal liquid, seasoning, and liquid food, etc., which are not limited here.
