Bottle mouth limiting valve structure with good adaptability

Abstract

The utility model discloses a bottle mouth limiting valve structure with good adaptability, which comprises a bottle body and a discharge nozzle arranged on the bottle body, an inner support is arranged at the discharge nozzle, a limiting valve is arranged on the inner support in a matching way, an outer support is detachably arranged in the discharge nozzle, and the inner support is clamped in the outer support. Due to the fact that the inner support is fixed in the discharging nozzle through the outer support, the inner support does not need to be fixed through a bottle cap, a flip cover can be used, a screw cap can also be used, paste can be directly extruded on a bottle for use, adaptability is better, and use is more convenient. In actual use, the inner support and the limiting valve can be kept unchanged and serve as standard parts, if a larger bottle body needs to be adapted, only the outer support needs to be enlarged correspondingly, molds of the inner support and the limiting valve do not need to be developed repeatedly, and the bottle bodies of various sizes can be adapted only by developing the mold of the outer support. Not only is die cost saved, but also stable product quality can be guaranteed.

Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a bottle mouth limiting valve structure with good adaptability. Background Art

[0002] Existing pastes are often used in bottles. As long as the bottle is squeezed, the paste will be discharged through the discharge hole of the bottle cap. Common pastes include cosmetic pastes, cleaning pastes and the like. However, since some hoses for cosmetics or cleaning pastes can only be placed upside down or lying flat, due to the effect of their own gravity, part of the paste will leak into the cap and flow back into the bottle when used, causing pollution. In addition, when squeezing the hose, it is easy to squeeze too much at a time, causing waste.

[0003] In view of this, a silicone valve cover is disclosed on the market, including a cover body and a silicone membrane. The cover body is provided with a discharge hole, the silicone membrane is sealed in the discharge hole, and the silicone membrane is provided with a slit. The pressurized silicone membrane squeezes the slit to release the blockage of the discharge hole.

[0004] In view of this, our company applied for a utility model patent named "A hose limited extrusion structure" on May 22, 2023, with patent application number 202321244285.4. The above two problems are solved in this application, but in actual use, there are also the following two problems: First, when using this structure, the bracket and the limiting valve can only be pressed down by the lid, so only the flip cover can be used, and the screw cover cannot be used; second, for bottles of different sizes, the size of the discharge nozzle is also different, so different sizes of brackets and limiting valves are required, which requires frequent development of molds for brackets and limiting valves of different sizes to adapt, making the mold cost higher. Utility Model Content

[0005] The problem to be solved by the utility model is to provide a bottle mouth limiting valve structure with simple structure, reasonable design, low production cost and better adaptability.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a bottle mouth limiting valve structure with good adaptability, including a bottle body and a discharge nozzle arranged on the bottle body, an inner bracket is installed at the discharge nozzle, and a limiting valve is installed on the inner bracket, an outer bracket is detachably installed in the discharge nozzle, and the inner bracket is clamped in the outer bracket.

[0007] Preferably, in the above-mentioned bottle mouth limiting valve structure with good adaptability, an outer protruding ring is processed on the outer wall of the outer bracket, and the outer bracket is connected to the inner wall of the discharge nozzle in an interference fit manner through the outer protruding ring.

[0008] Preferably, in the above-mentioned bottle mouth limiting valve structure with good adaptability, a positioning ring and a clamping groove are respectively processed on the inner side of the outer bracket, and the inner bracket is clamped in the clamping groove.

[0009] The advantages and beneficial effects of the utility model are as follows: an inner bracket is installed at the discharge nozzle, a limited quantity valve is installed on the inner bracket, an outer bracket is detachably installed in the discharge nozzle, and the inner bracket is clamped in the outer bracket. Since the inner bracket is fixed in the discharge nozzle by the outer bracket, it is not necessary to rely on the bottle cap to fix the inner bracket, and not only a flip cap but also a screw cap can be used, and the paste can be squeezed directly on the bottle for use, which has better adaptability and is more convenient to use; in actual use, the inner bracket and the limited quantity valve can be kept unchanged as a standard part. If a larger bottle body is to be adapted, it is only necessary to increase the size of the outer bracket accordingly. There is no need to repeatedly develop molds for the inner bracket and the limited quantity valve. Only the mold of the outer bracket needs to be developed to adapt to bottles of various sizes, which not only saves mold costs but also ensures stable product quality.

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the following is combined with the drawings and embodiments. The following is combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solution in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-Figure 7 As shown, a bottle mouth limiting valve structure with good adaptability includes a bottle body 1 and a discharge nozzle 2 arranged on the bottle body 1, an inner bracket 3 is installed in the discharge nozzle 2, a plurality of discharge ports 9 are opened on the bottom surface of the inner bracket 3, a limiting valve 4 is installed on the inner bracket 3, an outer bracket 5 is detachably installed in the discharge nozzle 2, the inner bracket 3 is clamped in the outer bracket 5, an outer protruding ring 6 is processed on the outer wall of the outer bracket 5, the outer bracket 5 is connected to the inner wall of the discharge nozzle 2 by interference fit through the outer protruding ring 6, a positioning ring 7 and a clamping groove 8 are respectively processed on the inner side of the outer bracket 5, and the inner bracket 3 is clamped in the clamping groove 8.

[0020] Since the inner bracket 3 is fixed in the discharge nozzle 2 by the outer bracket 5, there is no need to rely on the bottle cap to fix the inner bracket 3. Not only can the flip cap but also the screw cap be used, and the paste can be squeezed directly on the bottle for use, which has better adaptability and is more convenient to use. In actual use, the inner bracket 3 and the limiting valve 4 can be kept unchanged as a standard part. If a larger bottle body 1 is to be adapted, it is only necessary to increase the size of the outer bracket 5 accordingly. There is no need to repeatedly develop the molds of the inner bracket 3 and the limiting valve 4. Only the mold of the outer bracket 5 needs to be developed to adapt to bottles of various sizes. This not only saves the mold cost but also ensures stable product quality.
