Description

Technical Field

[0001] The invention relates to the technical field of daily chemical product packaging containers, and in particular to a replaceable dispensing device. Background Art

[0002] The dispensing device refers to a device used for dispensing and releasing, generally including a liquid storage component and a dispensing component, and a pump and a valve are common dispensing components. Since the service life of the dispensing component is relatively long, in the prior art, the liquid storage component is usually designed to be detachable and replaceable. When the liquid is used up, the empty liquid storage component can be removed and a new liquid storage component filled with liquid can be assembled onto the dispensing component for continued use.

[0003] In the prior art, a seal (such as a screw cap or a seal sticker) is provided at the opening of a liquid storage component for replacement. When replacement is required, the seal is usually removed first, and then the liquid storage component and the distribution component are assembled together. After the seal is removed, the opening of the liquid storage component is exposed, and it is very easy to tip over or even overturn during the assembly process, which not only causes waste or contamination of the liquid, but the overflowed liquid is also easy to corrode metal components such as springs in the distribution mechanism.

[0004] In addition, during transportation or accidental dropping, especially when encountering "violent express delivery", the seal at the opening of the liquid storage component is easily damaged due to the great impact force, causing unnecessary losses to merchants, consumers or couriers. Summary of the invention

[0005] In view of the above-mentioned defects of the prior art, the present invention provides a replaceable dispensing device, comprising:

[0006] A replaceable component includes a liquid storage container, wherein the first end of the liquid storage container has a first opening, the first opening is provided with a sealing member for sealing the first opening, the sealing member includes a first sheath portion and a flow guide portion connected to the first sheath portion, the flow guide portion includes a plurality of flow guide flaps, the plurality of flow guide flaps are connected to each other for sealing, a circle of thin-walled area is provided at the connection between the first sheath portion and the flow guide portion, and the wall thickness of the thin-walled area is less than the wall thickness of the first sheath portion and the flow guide flap;

[0007] The dispensing mechanism comprises a piercing member, and the piercing member is used to pierce the guide portion.

[0008] Furthermore, the puncture member includes a second sheath portion and a puncture portion connected to the second sheath portion, and the lower end portion of the puncture portion is in a cone shape to facilitate puncturing the guide membrane.

[0009] Furthermore, the second sheath can be inserted into the first sheath, and a sealing ring is provided on the inner wall of the upper part of the first sheath, which protrudes toward the axial direction of the first sheath. During replacement and use, the sealing ring is used to prevent the liquid from overflowing from between the first sheath and the second sheath, thereby corroding the distribution mechanism. During the replacement process, especially when the guide part is punctured, the lower part of the first sheath is easily pulled to deform, so in order to ensure the seal between the first sheath and the second sheath, the sealing ring is provided on the upper part of the first sheath.

[0010] Furthermore, the first sheath portion extends downward along the axial direction of the liquid storage container so that at least a portion of the first sheath portion is accommodated in the liquid storage container, and the first sheath portion is in airtight connection with the inner wall of the liquid storage container to reduce the risk of liquid overflowing from between the first sheath portion and the inner wall of the liquid storage container, thereby protecting the dispensing mechanism.

[0011] Furthermore, the first end of the liquid storage container is provided with a first annular edge, the upper part of the first sheath is provided with a second annular edge protruding in a direction away from the axis of the first sheath, the outer edge of the second annular edge is provided with a buckle edge folded downward, the second annular edge is buckled above the first annular edge so that the buckle edge buckles into the outer edge side of the first annular edge, so that the sealing member is fixed at the first opening of the liquid storage container. In addition, the second annular edge can further prevent the liquid from overflowing from between the first sheath and the inner wall of the liquid storage container, thereby increasing the sealing performance.

[0012] Furthermore, the replaceable component also includes a first shoulder sleeve, which is arranged on the outside of the first opening of the liquid storage container. The first shoulder sleeve is provided with a third annular edge, and the third annular edge is pressed on top of the second annular edge to further fix the seal at the first opening.

[0013] Furthermore, the dispensing mechanism also includes a second shoulder sleeve, a pump body that can be combined with the second shoulder sleeve, and an elastic mechanism mounted on the outside of the pump body, the second shoulder sleeve is detachably connected to the upper part of the liquid storage container, the piercing member is connected to the inner wall of the second shoulder sleeve and extends downward along the axial direction of the second shoulder sleeve, at least a portion of the pump body can be accommodated in the liquid storage container, and the dispensing mechanism is used to discharge the contents of the liquid storage container.

[0014] Furthermore, the seams between the guide flaps form a tearing zone, and the wall thickness of the tearing zone is smaller than the wall thickness of the guide flaps.

[0015] Furthermore, the outer surface of the guide flap is provided with reinforcing ribs protruding outward along the outer surface of the guide flap, and the reinforcing ribs are used to increase the rigidity of the guide flap and reduce the risk of accidental tearing of the tearing zone due to excessive deformation of the guide flap when it is subjected to unexpected impact forces such as collision.

[0016] Furthermore, a crack-stopping rib is provided at the connection between the tearing zone and the thin-walled zone, the width of the crack-stopping rib is greater than the width of the tearing zone, the wall thickness of the crack-stopping rib is greater than the wall thickness of the tearing zone and the thin-walled zone, and the crack-stopping rib is used to prevent the thin-walled zone from being torn.

[0017] Furthermore, the wall thickness of the thin-walled area is less than or equal to two-thirds of the wall thickness of the first sheath portion, so as to ensure that the thin-walled area can be deformed first to serve as a buffer when the guide portion is impacted.

[0018] Furthermore, the number of the guide flaps is n, 3≤n≤5, so as to simultaneously meet the requirements that the guide flaps can be opened radially when the guide portion is punctured and the tearing areas between the guide flaps can be fully torn.

[0019] Beneficial effects of the present invention:

[0020] 1. The device can be replaced safely without removing the seal first. When the liquid storage container is assembled to the predetermined position, the seal can be automatically released. The operation is simple and convenient. It can effectively prevent the pouring and leakage of the liquid during the replacement process. At the same time, it can effectively protect the parts in the distribution mechanism to prevent them from being corroded or contaminated by the leaked liquid.

[0021] 2. This device can effectively reduce the risk of accidental failure of the seal on the liquid storage container during transportation or use, and increase the reliability of the seal of the liquid storage container. This device sets a thin-walled area at the connection between the guide part and the first sheath part of the seal. When the liquid storage container is impacted by external force due to shock or falling, the thin-walled area will be the first to deform and act as a buffer, thereby effectively reducing the risk of accidental cracking of the guide part.

[0022] 3. This device has a simple structure, stable functions, and good sealing performance, and can provide consumers with a better user experience.

[0035] In order to make the technical means, creative features, objectives and effects of the invention easier to understand, the invention is further described below with reference to specific diagrams. However, the invention is not limited to the following implementation cases.

[0036] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings in this specification are only used to match the contents disclosed in the specification so as to facilitate understanding and reading by persons familiar with this technology. They are not used to limit the conditions under which the present invention can be implemented, and therefore have no substantive technical significance. Any structural modification, change in proportion or adjustment of size, without affecting the effects and purposes that can be achieved by the present invention, should still fall within the scope of the technical contents disclosed by the present invention.

[0037] like Figure 1 and Figure 2 As shown, the present invention discloses a replaceable dispensing device, including a replaceable component and a dispensing mechanism 2 , wherein the replaceable component includes a liquid storage container 1 and a first shoulder sleeve 14 .

[0038] like Figure 3 As shown, the first end of the liquid storage container 1 has a first opening 11, a sealing member 12 for sealing the first opening 11 is provided at the first opening 11, a first annular edge 13 is provided at the first end of the liquid storage container 1, and a first shoulder sleeve 14 is provided on the outer side of the first opening 11 of the liquid storage container 1.

[0039] like Figure 3 , Figure 6 , Figure 7 As shown, the sealing member 12 includes a first sheath portion 121 and a guide portion 122 connected to the first sheath portion 121. The first sheath portion 121 extends downward from the first opening 11 along the axial direction of the liquid storage container 1 so that at least a portion of it is accommodated in the interior of the liquid storage container 1, and the first sheath portion 121 is in airtight contact with the inner wall of the liquid storage container 1 to reduce the risk of liquid spilling from between the first sheath portion 121 and the inner wall of the liquid storage container 1, thereby preventing the dispensing mechanism 2 from being corroded or contaminated by the spilled liquid. A second annular edge 1211 is provided at the upper portion of the first sheath portion 121, which protrudes in a direction away from the axis of the first sheath portion 121. A buckle edge 1212 folded downward is provided at the outer edge of the second annular edge 1211. The second annular edge 1211 is buckled above the first annular edge 13 so that the buckle edge 1212 is buckled into the outer edge side of the first annular edge 13, thereby fixing the sealing member 12 at the first opening 11 of the liquid storage container 1. In addition, the second annular edge 1211 can further prevent the liquid from overflowing from between the first sheath portion 121 and the inner wall of the liquid storage container 1, thereby increasing the sealing performance.

[0040] like Figure 3 , Figure 6 , Figure 7 , Figure 8 As shown, the guide portion 122 includes guide flaps 1221, the number of which is three to five, and the guide flaps 1221 are connected to each other to form a seal. The number of guide flaps is required to simultaneously meet the requirements that the guide flaps 1221 can be opened radially when punctured and the connection between each guide flap 1221 can be fully torn. The tearing zone 1222 is formed by the seams between the guide flaps 1221, and the wall thickness of the tearing zone 1222 is less than the wall thickness of the guide flap 1221 to facilitate tearing. The outer surface of the guide flap 1221 is provided with a reinforcing rib 1223 protruding outward along the surface of the guide flap 1221 to increase the rigidity of the guide flap 1221 and reduce the risk of accidental tearing of the tearing zone 1222 due to excessive deformation of the guide flap 1221 when subjected to unexpected impact forces such as collision.

[0041] A circle of thin-walled area 123 is provided at the connection between the first sheath 121 and the guide portion 122. The wall thickness of the thin-walled area 123 is less than the wall thickness of the first sheath 121 and the guide flap 1221, and the wall thickness of the thin-walled area 123 is less than or equal to two-thirds of the wall thickness of the first sheath 121, so as to ensure that when the guide portion 122 is impacted, the thin-walled area 123 can be deformed first as a buffer, and when the wall thickness of the thin-walled area 123 is thin, it is easier to elastically deform. A crack-stopping rib 1231 is provided at the connection between the thin-walled area 123 and the tearing area 1222. The width of the crack-stopping rib 1231 is greater than the width of the tearing area 1222, and the wall thickness of the crack-stopping rib 1231 is greater than the wall thickness of the tearing area 1222 and the thin-walled area 123, so as to prevent the thin-walled area 123 from being torn.

[0042] like Figure 3 As shown, a third annular edge 141 is provided at the first shoulder sleeve 14 , and the third annular edge 141 is pressed on top of the second annular edge 1211 to further fix the sealing member 12 at the first opening 11 .

[0043] like Figure 1 , Figure 4 As shown, the dispensing mechanism 2 is used to discharge the contents in the liquid storage container 1, and includes a second shoulder sleeve 21, a pump body 22 that can be connected to the second shoulder sleeve 21, an elastic mechanism 23 sleeved on the outside of the pump body 22, and a nozzle 24 arranged above the second shoulder sleeve 21.

[0044] like Figure 2 , Figure 4 , Figure 5 As shown, the second shoulder sleeve 21 is connected to the upper part of the liquid storage container 1, and a piercing member 25 is arranged inside the second shoulder sleeve 22. The piercing member 25 includes a second sheath 251 and a piercing portion 252 connected thereto, and the lower end of the piercing portion 252 is in a cone shape to facilitate piercing the guide portion 122. The second sheath 251 can be inserted into the first sheath 121, and a sealing ring 1224 is arranged on the inner wall of the upper part of the first sheath 121, which protrudes toward the axial direction of the first sheath 121. During replacement and use, the sealing ring 1224 is used to prevent the liquid from overflowing from between the first sheath 121 and the second sheath 251, thereby corroding the dispensing mechanism. Since the lower part of the first sheath 121 is easily pulled to deform during the replacement process, especially when the guide portion 122 is pierced, in order to ensure the seal between the first sheath 121 and the second sheath 251, the sealing ring 1224 is arranged on the upper part of the first sheath 121.

[0045] As for the technical solution described in the above embodiment, the replacement and use methods are as follows:

[0046] When replacement is needed, the replaceable component is removed by using an empty liquid storage container 1 or the second shoulder sleeve 21, and then the replaceable component consisting of a new liquid storage container 1 and the first shoulder sleeve 14 is assembled onto the dispensing mechanism 2. When assembled to the predetermined position, the puncturing portion 252 of the puncturing member 25 pierces the guide portion 122, so that the tearing areas 1222 between the guide flaps 1221 are torn, and the guide flaps 1221 open outward, so that the seal 12 is released. At this time, the replacement is completed and the dispensing device of the present invention can be used normally.

[0047] When in use, the nozzle 24 is pressed to dispense the contents in the liquid storage container 1. When pressed, the elastic mechanism 23 is compressed, a pressure difference is generated inside and outside the pump body 22, and the one-way valve at the lower end of the pump body 22 opens. Under the action of the pressure difference, the contents enter the pump body 22 and are pumped out through the nozzle 24. When the hand is released, the elastic mechanism 23 rebounds to reset the nozzle 24, and the one-way valve in the pump body 22 is closed to stop pumping.

[0048] When the device is impacted by external force due to shock or falling, the thin-walled area 123 will deform first due to its thin wall thickness and relatively low strength, thereby providing a buffer for the flow guide 122. Since the thin-walled area 123 is arranged in a circle at the connection between the first sheath 121 and the flow guide 122, even when subjected to a large impact force, the flow guide 122 is not prone to large local deformation and is more inclined to move or deform as a whole, such as shrinking along the thin-walled area 123 into the first sheath 121 as a whole. In this way, the impact force that the flow guide 122 can bear is greatly improved, and the risk of accidental cracking and failure of the tearing area 1222 due to excessive local deformation is reduced.

[0049] It should be noted that the preferred specific embodiments of the present invention are described in detail above. It should be understood that ordinary technicians in the field can make many modifications and changes based on the concept of the present invention without creative work. Therefore, all technical solutions that can be obtained by technicians in the technical field based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should be within the scope of protection determined by the claims.
