Technical Field

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

[0002] Liquid spray guns are commonly used to apply coatings such as dyes, primers, paints, and sealants to surfaces. In known spray guns, the spray bottle is the container used to hold the liquid during spraying, and it is used in conjunction with the spray nozzle. Existing spray bottles are typically used inverted, and because the inside of the bottle is relatively sealed, this can easily lead to poor paint flow and excessive paint residue in the bottle during actual operation. Utility Model Content

[0003] The purpose of this utility model is to provide a spray bottle that can be connected to the external environment during actual use, which can better avoid the phenomenon of poor paint flow and excessive paint residue in the spray bottle.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] This utility model discloses a spray bottle, comprising:

[0006] The kettle body has a receiving cavity, and a vent valve seat is provided on the bottom wall of the kettle body. The vent valve seat has a mating groove, and the mating groove is connected to the receiving cavity.

[0007] The lid is rotatably connected to the vessel body and has a liquid outlet. At least two detachable sealing valves are provided on the outer wall of the lid. These sealing valves can be inserted into a mating groove to seal the groove, or they can be inserted into the outlet of an adapter connected to the liquid outlet to seal the adapter.

[0008] In some embodiments, at least one vent hole is provided on the inner peripheral wall of the mating groove, the vent hole is connected to the receiving cavity, and the sealing valve body can seal the vent hole when inserted into the mating groove.

[0009] In some embodiments, the sealing valve body includes: a base, a plunger portion connected to the base and capable of being inserted into the mating groove; and a connecting cylinder connected to the base and located radially outside the plunger portion, the connecting cylinder being sleeved on the vent valve seat.

[0010] In some specific embodiments, a first positioning ring is provided on one of the outer side wall of the plunger portion and the inner side wall of the mating groove, and a first positioning groove is provided on the other of the outer side wall of the plunger portion and the inner side wall of the mating groove, and the first positioning ring mates with the first positioning groove.

[0011] In some specific embodiments, a second positioning ring is provided on one of the inner sidewall of the connecting cylinder and the outer peripheral wall of the vent valve seat, and a second positioning groove is provided on the other of the inner sidewall of the connecting cylinder and the outer peripheral wall of the vent valve seat, and the second positioning ring cooperates with the second positioning groove.

[0012] In some embodiments, the lid is provided with a slot extending circumferentially thereon, and the upper end of the pot body is provided with a plug-in portion, which is plugged into the slot.

[0013] In some specific embodiments, the inner and outer sidewalls of the plug portion abut against two opposite sidewalls of the slot, and the top wall of the plug portion abuts against the top wall of the slot.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] In the description of this embodiment, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0029] This utility model discloses a spray bottle, with reference to... Figures 1-2 As shown, the spray bottle of this utility model includes a bottle body 100 and a cap 200. The bottle body 100 has a receiving cavity, and a vent valve seat 110 is provided on the bottom wall of the bottle body 100. The vent valve seat 110 has a mating groove 111, which is connected to the receiving cavity. The cap 200 is rotatably connected to the bottle body 100 and has a liquid outlet. At least two detachable sealing valve bodies 210 are provided on the outer wall of the cap 200. The sealing valve bodies 210 can be inserted into the mating groove 111 to seal the mating groove 111. Alternatively, the sealing valve bodies 210 can be inserted into the outlet of an adapter connected to the liquid outlet to seal the adapter. Understandably, in actual use, the sealing valve body 210 is first cut off from the cover 200, then inserted into the mating groove 111 to seal it, creating a semi-closed space in the spray bottle 100. Paint is then poured into the spray bottle 100, and the cover 200 is fixed inside. With the appropriate adapter, it is quickly connected to the spray gun. After confirming a secure connection, the spray gun can be reversed and used normally. During use, the sealing valve body 210 is pulled out from the vent valve seat 110. At this time, the internal environment of the spray bottle is connected to the external environment through the mating groove 111, effectively preventing uneven paint flow due to poor venting. This ensures smooth paint flow during use and reduces paint residue in the spray bottle. Meanwhile, if the spray gun needs to be temporarily removed from the adapter for work purposes, another sealing valve body 210 can be detached from the cover 200 and installed at the outlet of the adapter to seal the adapter, preventing external contaminants from entering the spray bottle 100 from the outlet. Furthermore, since the sealing valve body 210 is connected to the cover 200, it is less likely to be lost during transport or handling of the spray bottle, making it convenient for users.

[0030] Optionally, the sealing valve body 210 and the cover 200 are integrally formed, and there are multiple sealing valve bodies 210. This facilitates manufacturing, as a single mold can be used to form the sealing valve body 210 with the cover 200, reducing manufacturing costs. Furthermore, of the multiple sealing valve bodies 210, only one is used in actual operation, with the others as spares, avoiding the situation where the spray bottle becomes unusable due to the loss of one sealing valve body 210. In this embodiment, there are two sealing valve bodies 210. Of course, in other embodiments of this invention, the number of sealing valve bodies 210 can also be three, four, or even more, depending on actual needs.

[0031] It should be noted that, compared to existing spray bottles, the spray bottle in this embodiment does not have an inner cup or a sealing ring, resulting in fewer parts, easier assembly, and lower manufacturing costs. Furthermore, the lid 200 is designed to be stackable to achieve the smallest possible packaging size. The lid 200 and the bottle 100 together make for a smaller package of the same quantity of similar products, saving costs and materials.

[0032] Optional, see reference Figure 1 As shown, the spray bottle also includes a stopper 400. When the bottle body 100 contains sufficient paint, the cap 200 is screwed onto the outer cup, and then the liquid outlet on the cap 200 is blocked by the stopper 400 to prevent paint leakage and drying, and also to facilitate the storage and handling of unused paint. In use, the stopper 400 is removed, allowing the spray bottle to connect to the adapter or other connecting structures through the liquid outlet on the cap 200.

[0033] refer to Figure 3 As shown, the inner peripheral wall of the mating groove 111 is provided with at least one vent hole 112, which communicates with the receiving cavity. When the sealing valve body 210 is inserted into the mating groove 111, it can seal the vent hole 112. It is understood that during actual operation, the inside of the pot body 100 is under negative pressure. If the mating groove 111 penetrates the bottom wall of the pot body 100, backflow can easily occur inside the pot body 100 due to the negative pressure during operation. In severe cases, this may cause paint to spray out from the penetrating mating groove 111. In this embodiment, the mating groove 111 is located on the bottom wall of the pot body 100 and does not penetrate it. A vent hole 112 is provided on the inner peripheral wall of the mating groove 111 to achieve communication with the receiving cavity and the external environment. This concealed vent hole 112 can reduce the backflow caused by the negative pressure inside the pot and prevent paint from spraying out due to the negative pressure inside the pot.

[0034] Optionally, there are two vent holes 112, symmetrically arranged about the center of the mating groove 111. This facilitates manufacturing while ensuring stable communication between the receiving cavity and the external environment during use. Of course, in other embodiments of this invention, the number and arrangement of the vent holes 112 can be adjusted according to actual needs and are not limited to the foregoing limitations.

[0035] refer to Figure 2As shown, the lid 200 has a slot 220 extending circumferentially therefrom, and the upper end of the spray bottle 100 has a plug-in part 120, which is plugged into the slot 220. It is understood that in actual use, when the lid 200 is installed onto the spray bottle 100, the plug-in part 120 can be inserted into the slot 220. This ensures both the stability of the connection between the lid 200 and the spray bottle 100 and the airtightness of the connection, preventing paint leakage or the paint inside the spray bottle from drying out due to prolonged contact with air.

[0036] Optionally, the inner and outer walls of the insertion part 120 abut against the two oppositely arranged side walls of the slot 220, and the top wall of the insertion part 120 abuts against the top wall of the slot 220. It is understood that when the insertion part 120 is inserted into the slot 220, because the inner and outer walls of the insertion part 120 abut against the two oppositely arranged side walls of the slot 220, and the top wall of the insertion part 120 abuts against the top wall of the slot 220, this tight fit forms three sealing lines between the cap 200 and the bottle body 100, ensuring the sealing of the connection between the cap 200 and the bottle body 100, and preventing paint leakage or the paint in the spray bottle from drying out due to prolonged contact with air.

[0037] Optionally, the pot body 100 is provided with a first thread 130, and the lid 200 is provided with a second thread 230, with the first thread 130 and the second thread 230 being rotatably connected. It is understood that the pot body 100 and the lid 200 are connected by threads, and the lid 200 will tighten as it is screwed on, preventing the lid 200 from falling off, thereby ensuring the stability of the connection between the pot body 100 and the lid 200.

[0038] refer to Figure 4 As shown, the sealing valve body 210 includes a base 211, a plunger portion 212, and a connecting cylinder 213. The plunger portion 212 is connected to the base 211 and can be inserted into the mating groove 111. The connecting cylinder 213 is connected to the base 211 and is located radially outside the plunger portion 212. The connecting cylinder 213 is sleeved on the vent valve seat 110. It can be understood that in actual use, when the sealing valve body 210 is installed on the vent valve seat 110, the plunger portion 212 can be inserted into the mating groove 111 to seal the vent hole 112. The connecting cylinder 213 is sleeved on the outer periphery of the vent valve seat 110. Through the double-layer sealing structure, the connection between the sealing valve body 210 and the vent valve seat 110 can be sealed. When storing paint, it can ensure that the internal space of the spray bottle 100 is isolated from the external environment, preventing the paint in the spray bottle from drying out due to prolonged contact with air.

[0039] Optionally, a first positioning ring 2121 is provided on the outer side wall of the plunger portion 212, and a first positioning groove 113 is provided on the inner side wall of the mating groove 111. The first positioning ring 2121 mates with the first positioning groove 113. It is understood that when the plunger portion 212 is inserted into the mating groove 111 to block the vent 112, the first positioning ring 2121 mates with the first positioning groove 113. This serves two purposes: firstly, it provides positioning, ensuring that the plunger portion 212 can be stably connected to the mating groove 111; secondly, it ensures good sealing after the plunger portion 212 is inserted into the mating groove 111. This ensures that the internal space of the spray bottle 100 is isolated from the external environment when storing paint, preventing the paint in the spray bottle from drying out due to prolonged contact with air. Further, optionally, multiple first positioning rings 2121 are provided, spaced apart along the length of the plunger portion 212. This further improves the connection stability and sealing between the plunger portion 212 and the mating groove 111. Of course, in other embodiments of this utility model, a first positioning ring 2121 is provided on one of the outer side wall of the plunger portion 212 and the inner side wall of the mating groove 111, and a first positioning groove 113 is provided on the other of the outer side wall of the plunger portion 212 and the inner side wall of the mating groove 111, and the first positioning ring 2121 and the first positioning groove 113 are engaged.

[0040] Optionally, a second positioning ring 114 is provided on the outer peripheral wall of the vent valve seat 110, and a second positioning groove 2131 is provided on the outer peripheral wall of the connecting cylinder 213. The second positioning ring 114 and the second positioning groove 2131 cooperate. It can be understood that when the connecting cylinder 213 is fitted onto the vent valve seat 110, the cooperation of the second positioning ring 114 and the second positioning groove 2131 serves two purposes: firstly, it provides positioning, ensuring that the connecting cylinder 213 can be stably connected to the vent valve seat 110; secondly, it ensures good sealing between the connecting cylinder 213 and the vent valve seat 110, ensuring that the internal space of the spray bottle 100 is isolated from the external environment when storing paint, preventing the paint in the spray bottle from drying out due to prolonged contact with air. Further, optionally, multiple second positioning rings 114 are provided, spaced apart along the length of the plunger portion 212. This further improves the connection stability and sealing performance between the vent valve seat 110 and the connecting cylinder 213. Of course, in other embodiments of this utility model, the inner sidewall of the connecting cylinder 213 is provided with a second positioning ring 114, and the outer peripheral wall of the vent valve seat 110 is provided with a second positioning groove 2131.

[0041] Optionally, a notch 115 is provided on the outer peripheral wall of the vent valve seat 110. This facilitates machining.

[0042] Optional, see reference Figure 5As shown, the spray bottle also includes a filter screen 300, which is connected to the cap 200 and positioned directly opposite the liquid outlet. It is understood that the filter screen 300 filters paint stains and particles, making the paint finer and cleaner, thereby improving user satisfaction.

[0043] Alternatively, the cover 200 may be provided with a plurality of hooks 240 spaced apart along its circumference, and the filter screen 300 may be snapped onto the cover 200 via the hooks 240. Snapping the filter screen 300 onto the cover 200 facilitates the installation and removal of the filter screen 300.
