Description

Technical Field

[0001] This invention relates to the field of building materials, and more particularly to a multi-component film packaging. Background Technology

[0002] For multi-component chemical products, film bag packaging and rigid tube packaging are two commonly used packaging methods. Film bag packaging consists of multiple film bags and a header. During use, a pressing device and a sleeve are used to expel the chemical substances from the film bag through the outlet of the header. Once the chemical substances in the film bag are emptied, they can be removed from the sleeve and pressing device, allowing for the recycling of the sleeve and pressing device.

[0003] Based on the above, the film bag is only opened during use. In the prior art, different film bags can be configured to be opened simultaneously, such as the technical solution disclosed in S5697524. However, given that the components contained in the film bags are usually relatively hard substances, opening the film bags simultaneously requires the extrusion device to apply greater squeezing force. Therefore, in order to reduce the squeezing force requirement, technicians have considered setting the length of one film bag to be greater than the length of the other film bag, so that the longer film bag is subjected to the force of the extrusion device first and is opened before the shorter film bag. However, due to the difference in packaging bag length, it is easy to cause waste of chemical substances within a portion of the longer packaging bag. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-component film packaging for discharging component A and component B. On the one hand, it can enable the individual opening of different film bags, and on the other hand, it can reduce the length difference between different film bags and avoid waste of chemical substances.

[0005] To achieve the above objectives, the present invention provides a multi-component film packaging for discharging component A and component B through an outlet at the head, comprising:

[0006] A first film bag, for containing component A; and

[0007] The second film bag is used to hold component B.

[0008] The first and second film bags extend side-by-side along a longitudinal axis, and in particular parallel to the longitudinal axis, from back to front.

[0009] The head has a first receiving groove and a second receiving groove, which respectively receive the first film bag and the second film bag at the front end.

[0010] The head also includes a first opening structure located in the first receiving groove and a second opening structure located in the second receiving groove. The first opening structure has a first actuating portion for opening the first film bag, and the second opening structure has a second actuating portion for opening the second film bag, so that component A and component B flow out from the first film bag and the second film bag respectively, flow through the first receiving groove and the second receiving groove, and finally be discharged from the outlet, wherein the outlet is located between the first receiving groove and the second receiving groove and communicates with the first receiving cavity and the second receiving cavity.

[0011] Along the longitudinal axis, the first and second functional parts are located in different radial planes relative to the longitudinal axis.

[0012] In view of the above, in the technical solution provided by the present invention, the first functional part of the first opening structure and the second functional part of the second opening structure are respectively arranged on different radial surfaces. When pressure is applied along the longitudinal axis to the first film bag containing component A and the second film bag containing component B, the first functional part and the second functional part will contact the corresponding film bag at different times and thus open the corresponding film bag. In this way, the two film bags will be opened sequentially. At the same time, the sequential opening of the film bags is achieved by optimizing the first opening structure and the second opening structure, so the length difference between the two film bags in the prior art can be reduced (until the length difference is zero), thereby avoiding the waste of chemical components in longer film bags. In particular, when the two film bags have the same longitudinal length and pressure is applied to the two film bags on the same radial surface at the rear end by the extrusion device, one of them will contact the opening structure before the other.

[0013] Preferably, the first opening structure includes a first height, and the second opening structure includes a second height, wherein the first height and the second height are different. The height refers to the dimension along the longitudinal axis. Further, the first opening structure and the second opening structure can be configured to extend longitudinally from front to back, starting from the same radial plane but ending at different radial planes. The ending surfaces of the first opening structure and the second opening structure respectively constitute the first functional portion of the first opening structure and the second functional portion of the second opening structure. For example, the first opening structure and the second opening structure can start at the rear end of the outlet. In this way, by using opening structures with different heights, functional portions located on different radial planes are achieved, resulting in a relatively simple structure and manufacturing process.

[0014] Preferably, the height of the first opening structure for opening the first film bag containing component A is greater than the height of the second opening structure for opening the second film bag containing component B. Component A can be a curing agent, and component B can be the main agent. In this case, the first film bag containing the curing agent is opened before the second film bag containing the main agent.

[0015] Preferably, the first and / or the second functional part is configured to include a barbed structure or a scraper structure to reduce the contact area between the functional part and the corresponding film bag, increase the pressure, and make it easier to open the film bag.

[0016] Preferably, the first receiving groove includes a first annular wall, the second receiving groove includes a second annular wall, the first opening structure is located on the first annular wall, and the second opening structure is located on the second annular wall.

[0017] Preferably, the first opening structure includes two spaced-apart protrusions. Alternatively, the second opening structure includes two spaced-apart protrusions. In this way, the film bag is opened by tearing through the two protrusions, easily forming a large tear in the film bag to facilitate the leakage of chemical components inside.

[0018] Preferably, the two protruding elements of the first opening structure extend radially from the first annular wall. Alternatively, the two protruding elements of the second opening structure extend radially from the second annular wall.

[0019] Preferably, the distance between the radial surfaces of the first and second functional parts is 0.1 mm to 5 mm, particularly 0.3 mm to 1 mm. This distance prevents the longer functional part from puncturing the film bag during insertion (before use). This preferred range ensures that the film bag will not be punctured during assembly and transportation, while allowing the two film bags to be opened sequentially during use.

[0020] Preferably, the first film bag and the second film bag have substantially the same length along the longitudinal axis. In this invention, "substantially the same" means that the lengths are identical or the difference does not exceed 1 mm.

[0021] Based on this, the present invention arranges the actuating parts of two opening structures for opening corresponding film bags longitudinally back and forth, so that the film bag on one side first contacts the corresponding actuating part and is punctured, while the film bag on the other side is punctured subsequently. In this way, while allowing different film bags to be opened one by one, the length difference between the two film bags can be further reduced (ideally, the length difference is zero), thereby reducing material waste. Compared with the prior art, the technical solution provided by the present invention is more economical and environmentally friendly. Attached Figure Description

Detailed Implementation

[0028] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] In the description of this invention, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "lateral", and "longitudinal" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this invention.

[0030] As attached Figure 1As shown, this embodiment of the invention provides a multi-component film packaging, comprising: a first film bag 1 for containing component A; and a second film bag 2 for containing component B. The first film bag 1 and the second film bag 2 extend side-by-side along a longitudinal axis X from a rear end 4 to a front end 5. Both the first film bag 1 and the second film bag 2 are connected to a head 3 at the front end 5. Component A in the first film bag 1 and component B in the second film bag 2 can be discharged from an opening 31 located in the head 3. The outlet 31 constitutes the front end of the head 3.

[0031] Specific combination Figure 2 and Figure 3 The head 3 includes a first receiving groove 32 and a second receiving groove 33. The first film bag 1 is received in the first receiving groove 32, and the second film bag 2 is received in the second receiving groove 33. The opening 31 is located between the first receiving groove 32 and the second receiving groove 33, and communicates with both the first receiving groove 32 and the second receiving groove 33. When a force is applied forward along the longitudinal axis, component A in the first film bag 1 and component B in the second film bag 2 can be squeezed out and flow through the first receiving groove 32 and the second receiving groove 33 respectively, and finally be discharged from the opening 31. The outlet 31 is provided with an external thread 311, which can be threaded to a static mixer (not shown) to mix component A and component B in the mixer.

[0032] In use, the first film bag 1 is filled with component A and the second film bag 2 is filled with component B. At the same time, a corresponding sleeve (not shown), a piston (not shown) inside the sleeve, and a pressing device (not shown) are used to apply pressure from back to front along the longitudinal axis. The force is transmitted to the first film bag 1 and the second film bag 2 through the piston to squeeze and discharge the components A and B from the outlet 31 of the head 3.

[0033] Since the first film bag 1 and the second film bag 2 are in good condition without damage or opening before use, a corresponding structure is also required to open the first film bag 1 and the second film bag 2 during use.

[0034] like Figure 3 In the embodiment shown, the head 3 further includes: a first opening structure 34 located in the first receiving groove 32 for opening the first film bag 1; and a second opening structure 35 located in the second receiving groove 33 for opening the second film bag 2.

[0035] Further integration Figure 4 and Figure 5As shown, the first opening structure 34 includes a first actuating part 341, which can contact the first film bag 1 and destroy the packaging material of the first film bag 1 when a force is applied along the longitudinal axis X, thereby opening the first film bag 1 and allowing component A to flow out from the first film bag 1.

[0036] Correspondingly, the second opening structure 35 includes a second actuating part 351, which is configured to contact the second film bag 2 and, when a force is applied along the longitudinal direction, can break the outer packaging of the second film bag 2, thereby opening the second film bag 2 and allowing the B component to flow out from the second film bag 2.

[0037] In the technical solution provided by the embodiments of the present invention, along the longitudinal axis X, the first functional part 341 and the second functional part 351 are located in different radial surfaces 62 and 63, such as... Figure 4 As shown. In this way, when a pressure force is applied from back to front along the longitudinal axis X, the first actuating part 341 and the second actuating part 351 contact the corresponding film bags 1 and 2 at different times and thus open the corresponding film bags 1 and 2.

[0038] like Figure 4 In the illustrated embodiment, the radial surface 63 where the first actuating part 341 is located is closer to the rear end 4 than the radial surface 62 where the second actuating part 351 is located. Therefore, when a force is applied, the first actuating part 341 first contacts the first film bag 1 and opens the first film bag 1, and the second actuating part 351 subsequently contacts the second film bag 2 and opens the second film bag 2, thereby realizing the sequential opening of the first film bag 1 and the second film bag 2.

[0039] In some embodiments, the first actuating part 341 may also be disposed behind the second actuating part 351, so that the first film bag 1 is opened before the second film bag 2.

[0040] Continue back Figure 4In one embodiment of the present invention, the height of the first opening structure 34 (measured from the first radial surface 61 to the third radial surface 63 at the front end) is set to be greater than the height of the second opening structure 35 (measured from the first radial surface 61 to the third radial surface 62 at the front end). Specifically, the first opening structure 34 and the second opening structure 35 extend longitudinally from the same radial surface and stop at different radial surfaces, thereby placing the first functional part 341 and the second functional part 351 in different radial surfaces. It is worth noting that the scope of protection of the present invention is not limited to achieving the first functional part 341 and the second functional part 351 located in different radial surfaces through the height difference between the first opening structure 34 and the second opening structure 35; the positional relationship between the first functional part 341 and the second functional part 351 can also be achieved through other means.

[0041] Furthermore, along the longitudinal axis X, the distance between the first functional part 341 and the second functional part 351 can be set to be within the range of 0.1 mm to 5 mm. The lengths of the first film bag 1 and the second film bag 2 can be set to be substantially the same. It is worth noting that, in this invention, "substantially the same length" means that the length difference between the first film bag 1 and the second film bag 2 does not exceed 1 mm.

[0042] In an embodiment of the invention, the first functional part 341 and the second functional part 351 may be configured to include a scraper structure, such as... Figure 4 As shown.

[0043] Furthermore, the first actuating part 341 is located on the first annular wall 321 of the first receiving groove 32 and extends radially from the first annular wall 321. The second actuating part 351 is located on the second annular wall 3331 of the second receiving groove 33 and extends radially from the second annular wall 3331 of the second receiving groove 33.

[0044] The first opening structure 34 and the second opening structure 35 shown in the attached figures are merely examples, and the opening structures can also be configured to other structures suitable for opening the film bag.

[0045] For example, the first and second functional parts may also be configured to include a spike structure (not shown in the figures). The first and second opening structures are respectively fixed to the first receiving groove 32 and the second receiving groove 33, and extend longitudinally toward the rear end 4.

[0046] This invention does not limit the specific form of the opening structure, but only limits the positional relationship between the two functional parts used to open different film bags.

[0047] Furthermore, it is worth noting that the two-component film packaging shown in the accompanying drawings is merely an example, and the scope of protection of this invention is not limited to two-component packaging, but should also cover three-component and other multi-component film bag packaging. In the case of multi-component packaging, the inventive objective of this invention can be achieved as long as the opening structures corresponding to any two film bags are not on the same radial plane.

[0048] The above description is merely a preferred embodiment of the present invention and does not limit the implementation and protection scope of the present invention. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
