Description

Technical Field

[0001] This utility model belongs to the field of packaging hose technology, specifically relating to a silicone valve and a packaging hose. Background Technology

[0002] Packaging tubes used for containing pastes and liquids can be applied in various fields such as food, pharmaceuticals, cosmetics, and oral care. By squeezing the side wall of the packaging tube, the internal pressure is increased, allowing the paste or liquid to be smoothly extruded from the outlet. Users can control the extrusion volume by adjusting the squeezing force on the tube wall according to their usage needs; however, this method makes precise control of the extrusion volume difficult.

[0003] Adding a one-way silicone valve to the packaging tube can limit the amount of paste or liquid extruded. Currently, for products requiring large single-displacement volumes, such as shampoos and facial cleansers, the only way to achieve this is by continuously increasing the size of the silicone valve's outlet. Depending on the product and its extrusion volume requirements, manufacturers need to develop one-way silicone valves of different sizes and specifications, requiring multiple sets of molds. However, controlling multiple specifications during actual production can easily lead to various production problems and increase costs. Therefore, there is an urgent need to design a silicone valve product with adjustable outlet area and a packaging tube incorporating this valve. Summary of the Invention

[0004] To overcome the shortcomings and drawbacks of existing technologies, the primary objective of this utility model is to provide a silicone valve. This silicone valve has a thin-in-the-middle, thick-around-the-edge arc-shaped structure, comprising an outer arc structure and an inner arc structure, which are concentric arc structures. This silicone valve allows control of the material discharge rate simply by changing the size of the punched and cut discharge port.

[0005] The second objective of this invention is to provide a silicone valve packaging hose, which includes the aforementioned silicone valve. This silicone valve packaging hose inherently possesses the function of adjusting the liquid outlet area, making it suitable for pastes or liquid products where the discharge volume requires control.

[0006] The primary objective of this utility model is achieved through the following technical solution:

[0007] A silicone valve includes an outer arc-shaped structure and an inner arc-shaped structure, which are concentric circular arc structures. The wall thickness of the outer arc-shaped structure is greater than that of the inner arc-shaped structure (thinner in the middle and thicker around the edges). The outer arc-shaped structure includes a silicone platform and a support mounting platform. The silicone platform is located at the upper part of the outer arc-shaped structure, and the support mounting platform is located at the lower part of the outer arc-shaped structure. The inner arc-shaped structure includes a deformation groove, a punch, a thin sheet area, and a silicone discharge area. The thin sheet area is located on the silicone platform, the deformation groove is located on the silicone discharge area and close to the support mounting platform, and the punch is located in the middle of the silicone discharge area.

[0008] Preferably, the depth of the deformation groove is 1.1 to 1.3 times the wall thickness of the silicone outlet area.

[0009] Preferably, the punch is provided with an open guide structure.

[0010] Preferably, the opening guide structure is a guide design.

[0011] Preferably, the punching can be a triangular cut, a cross-shaped cut, a straight cut, or a snowflake-shaped cut.

[0012] Preferably, the kerf size of the punch is 0.1~0.2mm.

[0013] The second objective of this utility model is achieved through the following technical solution:

[0014] A silicone valve packaging hose includes a cap, a silicone valve, a bracket, a tube head, and a tube body. The cap is detachably connected to the silicone valve, the silicone valve is detachably connected to the bracket, the cap is detachably connected to the tube head, and the tube head and tube body are integrally formed.

[0015] Preferably, the cover includes an upper cover and a lower cover. The lower cover includes a liquid outlet, a liquid outlet platform, a mounting cable, and a fastening thread. The liquid outlet is located in the center of the liquid outlet platform, and a mounting cable is provided at the lower part of the liquid outlet platform. The lower cover is engaged with the bracket through the mounting cable.

[0016] Preferably, the lower part of the mounting cable is provided with an internal thread, and the outside of the tube head is provided with an external thread. The external thread and the internal thread cooperate to make the cover body and the tube head threadedly connected.

[0017] Preferably, the bracket and the silicone valve have an arc-shaped structure with the same center, and the bracket is sleeved on the outside of the silicone valve.

[0018] Preferably, the bracket includes a bracket buckle, a bracket mounting groove, and a bracket through hole. The bracket buckle is located at the upper part, the bracket mounting groove is located below the bracket buckle, and the bracket through hole is located in the middle of the bracket. The bracket buckle cooperates with the cover, the bracket mounting groove cooperates with the bracket mounting platform, and the bracket through hole cooperates with the punch hole.

[0019] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0020] (1) In the prior art, silicone valves are relatively small in size. In order to facilitate the flow of material, silicone valves are generally made into an arc-shaped structure with a thin middle and thick sides. This means that when the silicone valve is squeezed by the material, it can only deform through the weak middle part to discharge the material. However, this results in a small projected area for discharge. This invention increases the projected area of ​​the silicone valve by reasonably designing the deformation area of ​​the silicone valve and increasing the deformation area of ​​the thick walls around the perimeter. This increases the projected area when the liquid is discharged, thereby increasing the discharge volume. This invention fully considers the characteristics of silicone material. The deformation area (thin sheet area and deformation groove) and the middle area (silicone discharge area) have the same or similar material thickness, which is more conducive to rapid recovery after deformation. When the packaging containing this silicone valve is squeezed by hand, the material can be discharged quickly. When the hand is released, the material discharge can be stopped quickly, and the silicone valve rebounds quickly to stop the material discharge, thereby achieving the effect of cutting off the material.

[0021] (2) By designing the outline and deformation area of ​​the silicone valve punch, it is beneficial for the silicone valve to deform and achieve the purpose of rapid liquid discharge. The present invention further sets an opening guide structure according to the outline of the silicone valve punch. After punching, the wall thickness around the opening guide structure will become thinner and easier to deform, forming an opening, making it easier for the paste to punch open the silicone valve and the pressure required to generate deformation is smaller. It drives the silicone valve to generate efficient deformation, achieving the effect of maximizing the projected area. The cut size of the punch is limited to 0.1-0.2mm. This cut size is limited because when the hole is opened, the smaller the gap, the smaller the burr residue after the soft rubber is punched. When the packaging tube containing the silicone valve is filled with water-like contents and then inverted, the water-like contents will not easily overflow or seep out from the cut edge of the silicone valve punch due to the tension of the water-like contents themselves. Because the cut size of the punch is small, it has an obvious cutting effect when the water-like contents are squeezed out. Attached Figure Description

Detailed Implementation

[0039] The present invention will be further described in detail below with reference to specific embodiments, but the implementation of the present invention is not limited thereto. All materials used in the embodiments of the present invention can be purchased commercially.

[0040] Example 1 (Adding a deformation groove)

[0041] like Figures 1 to 3 As shown, the silicone valve in this embodiment includes an outer arc-shaped structure and an inner arc-shaped structure, which are concentric circular arc structures. The wall thickness of the outer arc-shaped structure is greater than that of the inner arc-shaped structure (thinner in the middle and thicker around the edges). The outer arc-shaped structure includes a silicone platform 21 and a bracket mounting platform 26. The silicone platform 21 is located at the upper part of the outer arc-shaped structure, and the bracket mounting platform 26 is located at the lower part of the outer arc-shaped structure. The inner arc-shaped structure includes a deformation groove 22, a punch 23, a thin sheet area 24, and a silicone discharge area 25. The thin sheet area 24 is located on the silicone platform 21, the deformation groove 22 is located on the silicone discharge area 25 and close to the bracket mounting platform 26, and the punch 23 is located in the middle of the silicone discharge area 25.

[0042] Preferably, the depth of the deformation groove 22 is 1.1 to 1.3 times the wall thickness of the silicone outlet area 25.

[0043] like Figure 4 As shown, the punch 23 is provided with an opening guide structure 231, which is a guide design. In this embodiment, the punch 23 is a cross-shaped cut; however, the punch 23 can also be a triangular cut, a straight cut, or a snowflake-shaped cut. The opening guide structure 231 is easily deformable, forming an open sheet.

[0044] Preferably, the cut size of the punch is 0.1~0.2mm. This cut size is limited because a smaller gap during punching results in less burr residue after punching the soft rubber. Specifically, an opening guide structure 231 is added at the punch 23. This structure uses a guiding design. After the required amount of contents (paste or liquid) is squeezed out, the hose is released, the pressure applied to the hose wall disappears, and a semi-vacuum state is formed inside the hose. The external atmospheric pressure will force the contents (paste or liquid) at the outlet back into the packaging hose. To prevent the contents (paste or liquid) from accumulating at the outlet, the opening guide structure 231 is added to allow a small amount of paste or liquid to accumulate at the outlet. The paste quickly flows back into the tube. After a small amount of paste flows back, it forms a loose area with most of the paste at the outlet. With the help of the rapidly rebounding punch 23, the loose area is quickly cut off. Furthermore, after the soft glue is punched, if the glue is too thick, it is easy to cause small burrs on the punch 23. For liquid contents, when inverted, it is easy to slowly seep out from the punch 23. Adjust the thickness of the soft glue to 0.1-0.25mm. After punching, there are few burrs remaining around the punch 23.

[0045] Example 2

[0046] like Figures 5 to 7 As shown, the silicone valve packaging hose includes a cover 1, a silicone valve 2, a bracket 3, a tube head 4, and a tube body 5. The cover 1 is detachably connected to the silicone valve 2, the silicone valve 2 is detachably connected to the bracket 3, the cover 1 is detachably connected to the tube head 4, and the tube head 4 and tube body 5 are integrally formed.

[0047] like Figure 8 As shown, the cover 1 includes an upper cover 11 and a lower cover 12. The lower cover 12 includes a liquid outlet 121, a liquid outlet platform 122, a mounting cable 123, and a fastening thread 124. The liquid outlet 121 is located in the center of the liquid outlet platform 122. The lower part of the liquid outlet platform 122 is provided with a mounting cable 123. The lower cover 12 cooperates with the bracket 3 through the mounting cable 123.

[0048] Preferably, the lower part of the mounting cable 123 is provided with an internal thread 124, and the outside of the tube head 4 is provided with an external thread 41. The external thread 41 and the internal thread 124 cooperate to make the cover 1 and the tube head 4 threadedly connected.

[0049] Preferably, the bracket 3 and the silicone valve 2 have the same arc-shaped structure with the same center, and the bracket 3 is sleeved on the outside of the silicone valve 2.

[0050] like Figure 9As shown, the bracket 3 includes a bracket buckle 31, a bracket mounting groove 32, and a bracket through hole 33. The bracket buckle 31 is located at the upper part, the bracket mounting groove 32 is located below the bracket buckle 31, and the bracket through hole 33 is located in the middle of the bracket 3. The bracket buckle 31 cooperates with the mounting buckle 123 of the cover 1, the bracket mounting groove 32 cooperates with the bracket mounting platform 26, and the bracket through hole 33 cooperates with the punch hole 23.

[0051] like Figures 10 to 12 The image shows an assembly diagram of the silicone valve 2 and the bracket 3. Figures 13 to 14 The figure shows the assembly diagram of the cover 1, silicone valve 2 and bracket 3.

[0052] like Figures 15 to 16 The diagram shows the assembly of the pipe head and the pipe body. The pipe head 4 has an external thread 41 on its outside. The internal thread 125 mates with the external thread 41, so that the cover 1 is threadedly connected to the pipe head 4.

[0053] The silicone valve 2 described in this embodiment has a concentric arc-shaped structure that is thin in the middle and thick around the edges. When the silicone valve 2 is assembled into the packaging tube, pressure is applied to the tube body 5. Because the pressure inside the tube body 5 is greater than atmospheric pressure and the deformation pressure of the silicone valve 2, the contents (paste or liquid) inside the packaging tube are squeezed out. However, the projected area of ​​the thin middle section (silicone outlet area 25) is small. A deformation groove 22 is added near the surrounding walls, and the wall thickness of the deformation groove 22 is 1.1-1.3 times that of the silicone outlet area 25. When the silicone valve 2 is subjected to pressure, the deformation groove 22 deforms first, thereby increasing the projected area of ​​the outlet. The silicone valve 2 adopts a concentric arc-shaped structure to maximize the contact area between the contents and the silicone valve 2. During extrusion, the middle section is most prone to deformation due to its thin wall, and the contents are most easily squeezed out from the middle.

[0054] Comparative Example 1 (without adding deformation grooves)

[0055] This comparative example shows a silicone valve hose package without the added deformation groove 22. The difference between this silicone valve packaging hose and the silicone valve packaging hose described in Example 2 is that it does not have the deformation groove 22; all other structures are the same.

[0056] Test Experiment 1

[0057] This test experiment compares the liquid output of the packaging tubing assembled with the silicone valve described in Comparative Example 1 with that of the silicone valve prepared in Example 2.

[0058] The following table shows the parameters of the liquid output of the test contents for Comparative Example 1 (without deformation groove) and Example 2 (with deformation groove):

[0059] Table 1

[0060]

[0061] By comparing the packaging hoses of Comparative Example 1 and Example 2, it was found that when packaging hoses with the same tube body were filled with the same weight of water, subjected to the same weight of weight, and pressed for the same amount of time, the weight of the extruded water differed significantly when different silicone valves were assembled. Example 2 showed a 92% increase in water flow rate. This demonstrates that the packaging hose with the added deformation groove 22 in the silicone valve of Example 2 exhibits superior material extrusion effect and quantity compared to the packaging hose of Comparative Example 1 without the deformation groove 22.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
