[0027] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0028] Example 1

[0029] like Figures 1 to 5 The figure shows a quantitative control valve according to an embodiment of the present invention. A quantitative control valve comprises two shells 10, each of which is concave inward to form a cavity 102, and a plurality of partitions 104 are arranged horizontally from top to bottom in the cavity 102, and each partition 104 is provided with a groove 106; the two shells 10 can be combined with each other to form a tubular structure 20, wherein the partitions 104 in one cavity 102 cooperate with the partitions 104 in the other cavity 102 to form a plurality of small compartments 108; and the grooves 106 on the partitions 104 cooperate to form various material passing holes 110; a feed port 30 is provided at the bottom of the tubular structure 20, and a discharge port 40 is provided at the top of the tubular structure 20.

[0030] Specifically, the quantitative control valve is usually installed in the inner cavity of the container near the outlet. The quantitative control valve is composed of two parts, which are a shell 10, which is concave inward to form a cavity 102. A plurality of partitions 104 are arranged in the cavity 102, wherein each partition 104 is spaced and arranged in parallel. The number of partitions 104 can be determined according to the size of the cavity 102 and the type of content (content properties such as viscosity, etc.). For example, when the viscosity of the content is high (i.e., not easy to squeeze out), the number of partitions 104 can be reduced and the spacing between the partitions 104 can be increased. In addition, each partition 104 is provided with a groove 106. The two parts (i.e., the housing 10) can be combined into a whole, i.e., the two cavities 102 are spliced ​​together to form a tubular structure 20, wherein inside the tubular structure 20, the partitions 104 at corresponding positions in the two cavities 20 cooperate with each other to divide the entire tubular structure 20 into a plurality of small compartments 108, which are used to store the contents, i.e., when the user presses or squeezes the contents in the container, the contents enter these small compartments 108. In addition, each partition 104 is provided with a groove 106, which cooperates with the groove 106 provided at the corresponding position in the other housing 10 to form a material passing hole 110. Each material passing hole 110 is combined to form a discharge channel, and the discharge channel transports the contents in the small compartment 108 in the quantitative control valve to the container outlet.

[0031] The quantitative control valve comprises two housings 10 (i.e., two parts), wherein each housing 10 is recessed inwardly to form a cavity 102, wherein a plurality of parallel partitions 104 are arranged in the cavity 102, and each partition 104 is provided with a groove 106. When the two housings 10 are combined, a tubular structure 20 can be formed. The partitions 104 can cooperate with each other to divide the tubular structure 20 into a plurality of small compartments 108, and the grooves 106 on the partitions 104 can also cooperate with each other to form feed holes 110, and each feed hole 110 is connected to form a discharge channel; a feed port 30 and a discharge port 40 are also provided on the tubular structure 20; the small compartments 108 in the quantitative control valve are used to store contents, and when the user squeezes the contents in the container, the contents enter the small compartments 108 through the feed port 30, and the flow of the contents is restricted when passing through the partition, and the contents can only reach the discharge port 40 through the discharge channel formed by the feed hole, ensuring that the amount of contents flowing out during each extrusion process is the same.

[0032] In one embodiment, if Figure 2 As shown, a first recess 112 is provided on the top of each shell 10 ; when the two shells are combined into one, the first recess 112 on each shell 10 cooperates with each other to form a discharge port 40 .

[0033] Specifically, each housing 10 has a first recess 112 on the top, and two first recesses 112 can be combined to form a hole, which is referred to as a discharge port 40. The discharge port 40 is used to discharge the contents in the small compartment 108. The above structure can ensure that the aperture of the discharge port 40 is small, so as to avoid excessive and too fast discharge of the contents so as to contaminate the bottle mouth of the container and cause waste.

[0034] In another embodiment, each partition is provided with a groove, and the groove is located in the middle of the partition.

[0035] Specifically, a groove can be provided on each partition, and when the two shells are combined into one, a discharge channel can be formed inside the tubular structure, and these discharge channels can finally collect the contents in the tubular structure to the discharge port, and then discharge them through the discharge port. Using a groove to form a discharge channel is convenient for discharging viscous or highly concentrated contents on the one hand, and convenient for quickly discharging a large amount of contents on the other hand.

[0036] In one of the embodiments, a supporting rib is provided on each partition, the height of the supporting rib is lower than the height of the partition to form the groove, and the supporting rib is provided in the middle of the partition.

[0037] Specifically, each partition is provided with a supporting rib, which is located in the middle of the partition and lower than the partition, and when the two shells are combined into one, a material passage is formed in the central position inside the tubular structure, so as to facilitate the content to be output from the container to the discharge port through the tubular structure.

[0038] In one embodiment, a second recess 114 is provided at the bottom of each shell 10 ; when the two shells are combined into one, the second recess 114 on each shell 10 cooperates with each other to form a feed port 30 .

[0039] Specifically, each housing 10 has a second recess 114 on the bottom, and two second recesses 114 can be combined to form a hole, which is referred to as a feed port 30. The feed port 30 is used to discharge the contents in the container through the tubular structure under the action of an external force (such as extrusion, etc.). The above structure can ensure that the aperture of the feed port 30 is small, so that too much content is prevented from entering the small compartment of the tubular structure and being difficult to discharge, thereby causing waste.

[0040] In one embodiment, an annular groove 50 is provided on the outer wall of each shell 10. When the two shells are combined into one, the annular groove 50 on each shell 10 is arranged around the outer wall of the tubular structure.

[0041] Specifically, the outer wall of each housing 10 is provided with an annular groove 50, which is used to fix the quantitative control valve at a position near the outlet in the container. Preferably, the annular groove 50 can be arranged around the entire housing 10, that is, when the two housings 10 are combined into one, the annular grooves 50 on the two housings 10 can match each other and then surround the outer wall of the entire tubular structure. That is, the annular grooves 50 can be arranged around the outer wall of the tubular structure, which can facilitate the fixing of the quantitative control valve to the greatest extent, and the fixing is very stable to avoid slipping.

[0042] In one embodiment, the partition is a plastic sheet partition.

[0043] In a preferred embodiment, the partition can be a plastic sheet partition. Plastic is mainly composed of carbon, oxygen, hydrogen and nitrogen and other organic or inorganic elements. The finished product is solid. It is a molten liquid during the manufacturing process. Therefore, it can be heated to melt, pressurized to flow, and cooled to solidify to form various shapes. During the processing, different additives can be added to form plastic (flexible) materials, or rigid materials formed by curing and cross-linking. Plastic sheet is one of the products made of plastic, and has a wide range of uses. In this embodiment, there are multiple plastic sheets, and multiple plastic sheets are installed inside the tubular structure, dividing the inner cavity of the tubular structure into multiple grids, each small grid has a port connected, and when the paste in the hose passes through the film, the flow rate is restricted. When the paste enters the second grid from the first grid, the flow rate is restricted and fixed, which makes the extruded paste also quantitative. When the quantitative control valve is used in the hose, the paste in the hose must be squeezed by a certain pressure to produce circulation and will not flow out naturally under the action of gravity. The purpose of this device is to ensure that when the paste is squeezed out, the paste will not flow out continuously but in the form of water drops.

[0044] Example 2

[0045] Based on the above quantitative control valve, the present invention also provides a quantitative hose.

[0046] A metering hose, such as Figures 6 to 8 As shown, it includes the quantitative control valve in any embodiment, and the quantitative control valve 100 is fixed in the inner wall of the pipe mouth of the hose 200.

[0047] Specifically, the quantitative control valve is arranged inside the hose mouth, and when the content (such as paste) in the hose needs to be squeezed out, the user squeezes the hose body, and the content will pass through the quantitative control valve and then reach the hose outlet. The quantitative control valve can effectively ensure that the amount of content squeezed out each time is the same.

[0048] The quantitative hose adopts the quantitative control valve, so the quantitative hose can ensure that the amount of content flowing out during each extrusion process is the same.

[0049] In a preferred embodiment, the discharge port of the quantitative control valve is flush with the liquid outlet nozzle of the hose to prevent a large amount of content from accumulating in the gap between the discharge port and the liquid outlet nozzle and being difficult to discharge, thereby causing waste.

[0050] In one of the embodiments, an annular clamping position is correspondingly provided on the inner wall of the hose pipe mouth, and the annular clamping position is clamped in the annular clamping groove of the quantitative control valve.

[0051] Specifically, an annular clamping position is provided inside the hose pipe mouth, and the annular clamping position is mainly used to clamp the annular clamping groove, so as to fix the quantitative control valve inside the hose pipe mouth.

[0052] In addition, the outer wall of the quantitative control valve is in contact with the inside of the hose, which prevents a large amount of content from being contaminated on the outer wall of the quantitative control valve and causing material waste.

[0053] In addition, the number of the annular clamping positions can be multiple, so that the quantitative control valve is more firmly fixed on the inner wall of the hose pipe mouth.

[0054] In one embodiment, if Figure 5 As shown, an external thread 300 is provided at the pipe opening of the hose 200, and the external thread 300 is used to connect the cover body of the hose.

[0055] Specifically, the outer side wall of the hose mouth is provided with an outer spiral, which is arranged corresponding to the spiral in the cover body, so that the cover body tightly covers the liquid outlet of the hose mouth to prevent the contents from flowing out due to external force (such as accidental pressing, etc.).

[0056] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
