Description

Technical Field

[0001] This utility model relates to packaging containers, and more particularly to an extrusion structure and its container. Background Technology

[0002] Packaging containers are widely used in daily life and industrial production, including condiment bottles, beverage bottles, or other solution bottles. The caps of containers commonly used for condiment bottles are generally threaded, requiring the cap to be unscrewed before pouring. This structure makes it difficult to control the amount poured out, which can easily lead to over-pouring and residue at the container opening after pouring. Moreover, containers with this structure are also prone to tipping over, causing all the solution inside to spill out.

[0003] Furthermore, some squeeze-type containers using valves can effectively control the liquid output and solve the problem of liquid residue to some extent. However, with this valve structure, the valve head is initially concave inwards. During use, the container needs to be squeezed until the valve head bulges outwards. This process requires overcoming not only the elastic deformation force of the valve head but also a force greater than its elastic deformation force to change the valve head from an inward-curved state to an outward-bulging state. Therefore, this valve structure has the drawback of requiring high squeezing force.

[0004] To address the aforementioned technical problems, this utility model has been further optimized and proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a foaming structure and its container. The foaming structure has a deformation connecting part and a foaming part. When the container using the foaming structure is squeezed, the deformation connecting part is squeezed and bulged first, and then the foaming part protrudes outward. With this structure, the squeezing action can be completed with a small force. It has the characteristics of easy squeezing out liquid and control of liquid output, and also effectively avoids the problem of liquid residue.

[0006] To solve the above-mentioned technical problems, this utility model provides a foaming structure, including a foaming structure body 1. The foaming structure body 1 is installed at the container opening 21 or on a cover located at the container opening 21. The foaming structure body 1 has a structural cavity 11, and the structural cavity 11 has a foaming part 13. The foaming part 13 and the foaming structure body 1 have an elastically deformable connecting part 12. The foaming part 13 has a liquid outlet 15. The deformable connecting part 12 and the foaming part 13 form a liquid outlet space 14 that communicates with the inner cavity of the container. The deformable connecting part 12 and the foaming part 13 are configured such that when the container is squeezed, the deformable connecting part 12 first elastically deforms to a preset degree, and then the foaming part 13 elastically protrudes away from the liquid outlet space 14 and towards the structural cavity 11, thereby opening the liquid outlet 15.

[0007] As described above, in a foaming structure, the foaming part 13 is recessed toward the liquid outlet space 14, or the foaming part 13 is protruding away from the liquid outlet space 14.

[0008] As described above, in a foaming structure, when the foaming part 13 elastically protrudes so that the liquid outlet 15 opens, the liquid outlet 15 extends and opens away from the liquid outlet space 14; and after the squeezing container force is removed, both the deformable connecting part 12 and the foaming part 13 elastically return to their initial shape.

[0009] As described above, in a foaming structure, when the foaming part 13 elastically protrudes so that the liquid outlet 15 opens, the liquid outlet 15 extends out of the upper edge of the structural cavity 11 away from the direction of the liquid outlet space 14 and opens; and after the squeezing container force is removed, the deformation connection part 12 and the foaming part 13 elastically reset their initial shape accordingly, and the foaming part 13 retracts into the structural cavity 11.

[0010] As described above, the extrusion structure 1 has a connecting structure 10 on its periphery for connecting with a cover, and the connecting structure 10 and the periphery sidewall of the extrusion structure 1 have a locking groove 16.

[0011] As described above, in the extrusion structure, the deformable connection 12 initially has a conical structure with its sidewalls protruding outwards.

[0012] In the extrusion structure described above, the deformable connection portion 12 initially has a concave-convex ring folded along its axial direction.

[0013] In the extrusion structure described above, the lower diameter of the deformable connecting part 12 is larger than its upper diameter.

[0014] Alternatively, in its initial state, the deformable connecting portion 12 has a concave-convex ring formed radially along its radial direction.

[0015] As described above, in a foam extrusion structure, a reflux groove 17 is formed between the deformable connecting part 12 and the inner side of the foam extrusion structure body 1. The bottom of the reflux groove 17 is provided with a one-way valve 18 that can unidirectionally replenish air into the inner cavity of the container and draw back the solution remaining on the reflux groove 17.

[0016] As described above, in a foam extrusion structure, the return channel 17 is inclined and has a low position portion 171, and the one-way valve 18 is disposed on the low position portion 171.

[0017] This utility model also provides a container, including a container body 2 with a container cavity and capable of being squeezed and deformed, the container body 2 having a container opening 21, and the container opening 21 being connected to the aforementioned extrusion structure.

[0018] As described above, in a container, the container opening 21 is connected to a cover seat 22, the cover seat 22 has a cover seat interface 23 communicating with the inner cavity of the container, the upper edge of the cover seat interface 23 extends inward and folds to form a barb 231, the extrusion structure is snapped onto the cover seat interface 23 by the barb 231, and the cover seat 22 can also be flipped to be connected to a flip cover 24 that is fastened to the cover seat interface 23.

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

[0020] 1. The present invention relates to a foaming extrusion structure and a container thereof. The foaming extrusion structure has an added deformation connection part, and the deformation connection part and the foaming part are configured to elastically deform and protrude outwards respectively. By utilizing the elastic deformation of the deformation connection part first, the foaming part can more easily protrude outwards. In the whole extrusion process, a small force is required to extrude the liquid.

[0021] 2. Because the extrusion part protrudes outward during extrusion, it prevents liquid residue from remaining in the structural cavity, ensuring clean and hygienic use.

[0022] 3. The extrusion section is recessed into the liquid outlet space, so that the liquid outlet is always kept closed when the extrusion structure does not protrude outward, thus achieving a good sealing effect and preventing leakage.

[0023] 4. By setting up a reflux trough and a one-way valve, when the squeezing is completed and the hand is released, due to the pressure difference between the inner cavity of the container and the outside, and the need for the container body to reset, the solution collected on the reflux trough will be automatically sucked back into the inner cavity of the container during the automatic air replenishment process through the one-way valve, so that the container body can quickly restore its shape, which is more conducive to repeated squeezing and use by the user.

[0024] 5. In order to ensure that all the liquid collected on the reflux tank is drawn back into the container cavity, the bottom of the reflux tank is set at an angle and the one-way valve is set at the lower position. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-14 The embodiments of this utility model will be described in detail.

[0041] like Figure 1-14As shown, this utility model discloses a foaming structure, including a foaming structure body 1. The foaming structure body 1 is installed at the container opening 21 or on a cap located at the container opening 21. The foaming structure body 1 has a structural cavity 11, and the structural cavity 11 has a foaming part 13. A deformable connection part 12 that can elastically deform is provided between the foaming part 13 and the foaming structure body 1. The foaming part 13 has a liquid outlet 15, which can be elastically cut and can automatically open under a certain pressure. The deformable connection part 12 and the foaming part 13 form a liquid outlet space 14 that communicates with the inner cavity of the container. Figure 3 , 4 As shown, the deformable connecting part 12 and the foaming part 13 are configured such that when the container is squeezed, the deformable connecting part 12 first elastically deforms to a preset degree, and then the foaming part 13 elastically protrudes away from the liquid outlet space 14 and towards the structural cavity 11, thereby opening the liquid outlet 15.

[0042] During the squeezing process, the outlet remains closed until the squeezing part extends outward. This process is similar to blowing up a balloon; when the balloon's opening bulges to a certain extent, the top begins to slowly extend and bulge. Based on this principle and fact, this invention adds a deformation connecting part structure and configures the deformation connecting part and the squeezing part to bulge outward and extend outward respectively. The bulging of the deformation connecting part makes it easier for the squeezing part to extend outward. During the entire squeezing process, a smaller force is required to squeeze out the liquid, making it convenient for users.

[0043] Corresponding to the structure of the foaming section, the foaming section 13 is recessed towards the liquid outlet space 14, or the foaming section 13 is protruding away from the liquid outlet space 14, such as... Figure 12 As shown. The extrusion section 13 of this utility model is preferably recessed. With this structural design, the liquid outlet is always kept closed when the extrusion structure is not protruding outward, thus achieving a good sealing effect and preventing leakage.

[0044] The extrusion section 13 elastically protrudes, causing the outlet 15 to open in a direction away from the outlet space 14 when the outlet 15 is opened; and after the extrusion force is removed, both the deformable connecting part 12 and the extrusion section 13 elastically return to their initial shape. Therefore, with this structural design, because the extrusion section protrudes outward during extrusion, as... Figure 12 As shown, this design prevents liquid residue from remaining in the structural cavity during extrusion, ensuring clean and hygienic use.

[0045] Furthermore, when the foaming part 13 elastically protrudes and the outlet 15 opens, the outlet 15 extends out of the upper edge of the structural cavity 11 away from the direction of the outlet space 14; and after the squeezing container force is removed, the deformable connecting part 12 and the foaming part 13 elastically reset their initial shape accordingly, and the foaming part 13 retracts into the structural cavity 11, so that the outlet is better hidden on the side of the structural cavity 11.

[0046] like Figure 2-8 As shown, the extrusion structure body 1 has a connecting part 11 on its periphery for connecting with the cover seat. The connecting part 11 and the periphery side wall of the extrusion structure body 1 have a locking groove 16 to facilitate assembly.

[0047] like Figure 1 , 2 As shown, the deformable connecting part 12 preferably has a conical structure in its initial state, with the sidewalls protruding outwards. This structure makes it easier to control the squeezing force and requires less force from the user to squeeze out the liquid.

[0048] As another embodiment of the deformable connection part 12, such as Figure 5 , 6 As shown, the deformable connecting portion 12 initially has a corrugated ring formed along its axial direction. Furthermore, the lower diameter of the deformable connecting portion 12 is larger than its upper diameter.

[0049] As another embodiment of the deformable connection part 12, such as Figure 7 , 8 As shown, in its initial state, the deformable connecting portion 12 has a concave-convex ring formed radially along its radial direction.

[0050] like Figure 2-8 As shown, a reflux groove 17 is formed between the deformable connecting part 12 and the inner side of the extrusion structure body 1. A one-way valve 18 is provided at the bottom of the reflux groove 17, which can unidirectionally replenish air into the container cavity and draw back the solution remaining on the reflux groove 17. By setting the reflux groove and the one-way valve in conjunction, when the extrusion is completed and the pressure is released, due to the pressure difference between the container cavity and the outside, and the need for the container body to return to its original position, the solution remaining on the reflux groove will be automatically drawn back into the container cavity during the automatic air replenishment process through the one-way valve. This allows the container body to quickly restore its shape, making it more convenient for users to repeatedly extrude and use. Figure 2 , 3 As shown in Figures 4 and 6, in order to ensure that all the liquid collected on the reflux tank is drawn back into the container cavity, the reflux tank 17 is inclined and has a low position portion 171, and the one-way valve 18 is disposed on the low position portion 171.

[0051] like Figure 13-14As shown, this utility model discloses a container, including a container body 2 with an inner cavity and capable of being squeezed and deformed. The container body 2 has a container opening 21, and the aforementioned extrusion structure is connected to the container opening 21. A cap seat 22 is connected to the container opening 21, and the cap seat 22 has a cap seat interface 23 communicating with the inner cavity of the container. The upper edge of the cap seat interface 23 extends inward and folds to form a barb 231. The extrusion structure is engaged with the cap seat interface 23 via the barb 231. A flip-top cap 24, which is also flipped and fastened to the cap seat interface 23, is also connected to the cap seat 22. Containers using this extrusion structure offer convenient and hygienic liquid extrusion.

[0052] When using this container, the user first opens the flip-top, then squeezes the container body 2 to deform it. At the beginning of the squeezing, the deformation connection part will elastically deform and bulge. When it bulges to a certain extent, the squeezing part will extend and bulge outward, eventually opening the liquid outlet and spraying out liquid. When the user releases the hand, under the action of the internal and external air pressure difference and the elastic force of the container body, air is quickly replenished through the one-way valve, so that the container body automatically and quickly returns to its shape. Moreover, if there is liquid remaining in the structural cavity after the liquid is squeezed out, the liquid collected by the return tank is automatically sucked back into the container cavity by the one-way valve during the air replenishment process, so it has the characteristics of cleanliness and hygiene.
