Description

Technical Field

[0001] This application relates to cosmetic packaging technology, specifically to an elastic film assembly and a material container containing the elastic film assembly. Background Technology

[0002] With the continuous development of cosmetic containers, containers with elastic membranes have emerged. These elastic membranes are perforated membranes that allow users to dispense cosmetic materials by squeezing the membrane. Elastic membranes are popular due to their advantages, including good sealing, easy control of the dispensing amount, and minimal residue. However, currently, elastic membranes are typically fixed inside the container using a snap-fit ​​method. Prolonged squeezing can cause the membrane to loosen and detach, leading to inconvenience for users. Utility Model Content

[0003] To overcome the above-mentioned defects, this application provides an elastic membrane assembly in which the elastic membrane is firmly fixed in the base by a hot-melt column on the base, thereby improving the installation firmness of the elastic membrane.

[0004] The technical solution adopted by this application to solve its technical problem is:

[0005] An elastic membrane assembly includes an elastic membrane and a base. The elastic membrane has a discharge channel, and a hot-melt column is fixed on the base. The elastic membrane is installed inside the base, and the hot-melt column passes through the elastic membrane. The hot-melt column is cured by high-temperature hot melting to fix the elastic membrane inside the base.

[0006] Optionally, the structure of the discharge channel includes at least one of cuts and holes.

[0007] Optionally, the elastic membrane is provided with mounting holes, the hot-melt column passes through the mounting holes, and the hot-melt column fixes the elastic membrane after being hot-melted at high temperature.

[0008] Optionally, the portion of the hot-melt column passing through the mounting hole is hot-melted at high temperature and then solidified to form a stop block, which clamps and fixes the elastic membrane together with the base.

[0009] Optionally, the elastic membrane includes a discharge section and a mounting section fixedly connected to the discharge section, the discharge channel is opened in the discharge section, the mounting hole is opened in the mounting section, and the thickness of the discharge section is less than the thickness of the mounting section.

[0010] Optionally, the upper surface of the discharge section is flush with the upper surface of the mounting section, and the lower surface of the discharge section is recessed into the lower surface of the mounting section.

[0011] Optionally, the base is provided with a raised edge that extends along the axial direction of the base, and the elastic membrane is placed inside the raised edge.

[0012] A material container includes an elastic membrane assembly, a cover assembly, and a bottom assembly, wherein the elastic membrane assembly is detachably mounted to the bottom assembly, and the cover assembly is sealed to the bottom assembly.

[0013] Optionally, the bottom assembly includes an outer bottom and an inner bottom fixedly installed within the outer bottom, and the elastic membrane assembly is detachably installed within the inner bottom.

[0014] Optionally, the bottom assembly includes an outer bottom, and the base also includes a locking portion, which is fitted onto the opening of the outer bottom and locked in place with the outer bottom.

[0015] The beneficial effects of this application are as follows: When no material is being used, the discharge channel on the elastic membrane is closed or has a small aperture. When material is being used, the user presses the elastic membrane to open the discharge channel, allowing the material to flow out for the user's use. In this application, the elastic membrane is installed inside the base and is firmly fixed to the base by a hot-melt column, thereby improving the installation stability of the elastic membrane. Since only hot-melt columns are used to fix the elastic membrane in this elastic membrane assembly, the number of components is reduced, the cost is lowered, and the overall weight and volume of the elastic membrane assembly are reduced, meeting the consumer demand for lightweight and thin products.

Detailed Implementation

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the embodiments of this application. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0031] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such uses of the terms can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0032] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0033] Example 1: As Figure 1-10 As shown, an elastic membrane assembly includes an elastic membrane 100 and a base 200. The elastic membrane 100 has a discharge channel 111, and a hot-melt column 210 is fixedly mounted on the base 200. The elastic membrane 100 is installed inside the base 200, and the hot-melt column 210 passes through the elastic membrane 100. The hot-melt column 210 is cured by high-temperature hot melting to fix the elastic membrane 100 inside the base 200. The elastic membrane 100 is made of materials including bioelastic materials such as sodium alginate, organosilicon film-forming agents such as MQ resin, and synthetic polymers such as PVA. The base 200 is made of plastic.

[0034] During use, the elastic membrane assembly is installed inside a container, which holds cosmetic materials. The elastic membrane 100 seals the materials within the container. When the materials are not in use, the discharge channel 111 on the elastic membrane 100 is closed or has a small aperture. When the materials are needed, the user presses the elastic membrane 100 to open the discharge channel 111, allowing the materials to flow out for the user. In this application, the elastic membrane 100 is installed inside the base 200 and is securely fixed to the base 200 by a heat-sealing column 210, thereby improving the installation stability of the elastic membrane 100. Since this elastic membrane assembly only uses the heat-sealing column 210 to fix the elastic membrane 100, the number of components is reduced, the cost is lowered, and the overall weight and volume of the elastic membrane assembly are reduced, meeting the consumer demand for lightweight and thin products.

[0035] Optionally, the structure of the discharge channel 111 includes at least one of a slit and a hole. A slit is a cut made in the elastic membrane 100 by a cutter. When not in use, the slit is closed, meaning the discharge channel 111 is in a closed state. The shape of the slit includes a straight line, a cross, a star shape, etc.

[0036] The elastic membrane 100 is provided with multiple discharge channels 111. In a first possible embodiment, such as... Figure 5-7 As shown, the discharge channel 111 is a straight cut. When the elastic membrane 100 is not pressed, it is in a closed state. When the elastic membrane 100 is pressed, it undergoes elastic deformation, and the cut is pulled open to form the discharge channel 111. In this embodiment, since the discharge channel 111 is normally in a closed state, the elastic membrane 100 effectively isolates the inside and outside of the container, resulting in a good sealing effect and helping to improve the storage conditions and shelf life of the material. In a second possible embodiment, the discharge channel 111 is shaped like a hole. The shape of the hole is not limited to circular, elliptical, square, etc. When the elastic membrane 100 is not pressed, the diameter of the hole is small. When the elastic membrane 100 is pressed, it undergoes elastic deformation, and the diameter of the hole expands, facilitating the flow of material. In this embodiment, the discharge channel 111 has a perforated structure, so the discharge points are relatively concentrated. In a third possible embodiment, part of the discharge channel 111 is a cut, and the rest is a hole. The structure of the discharge channel 111 can be selected according to actual needs. For example, a slit can be used for thinner materials, and a hole can be used for materials with high viscosity, thereby meeting diverse needs.

[0037] like Figure 2 and Figure 5 As shown, the elastic membrane 100 is provided with mounting holes 121, and the hot melt column 210 passes through the mounting holes 121. After the hot melt column 210 is hot melted at high temperature, the elastic membrane 100 is fixed.

[0038] like Figure 4-5 As shown, the portion of the hot-melt column 210 passing through the mounting hole 121 is hot-melted and solidified at high temperature to form a stop 211. The stop 211 and the base 200 clamp and fix the elastic membrane 100. Optionally, the width of the stop 211 is greater than the diameter of the mounting hole 121. The outer diameter of the hot-melt column 210 is less than or equal to the diameter of the mounting hole 121, which facilitates the assembly of the elastic membrane 100. The portion of the hot-melt column 210 extending out of the mounting hole 121 is hot-melted and pressed to form the stop 211. The width of the stop 211 is greater than the diameter of the mounting hole 121, which can effectively prevent the elastic membrane 100 from falling off.

[0039] like Figure 5 and Figure 8 As shown, the base 200 has an internally hollow disc-shaped structure. A ring of spaced-apart hot-melt pillars 210 is provided on the upper surface of the base 200, with equal distances between adjacent hot-melt pillars 210. Correspondingly, a ring of spaced-apart mounting holes 121 is provided on the elastic membrane 100. Figure 1-2 As shown, when the elastic membrane 100 is installed in the base 200, the hot-melt column 210 passes through the mounting hole 121, and a portion of the hot-melt column 210 extends out of the elastic membrane 100, as... Figure 3-4 As shown, a high-temperature metal block or other heat source is used to melt the part of the hot melt column 210 that extends out of the elastic membrane 100, and then solidify it to form a stop 211 that is fixed on the elastic membrane 100, thereby fixing the elastic membrane 100 to the base 200, thereby improving the bonding strength between the base 200 and the elastic membrane 100, and improving the installation stability of the elastic membrane 100.

[0040] like Figure 5-7 As shown, the elastic membrane 100 includes a discharge section 110 and a mounting section 120 fixedly connected to the discharge section 110. A discharge channel 111 is formed in the discharge section 110, and a mounting hole 121 is formed in the mounting section 120. The thickness of the discharge section 110 is less than the thickness of the mounting section 120. Figure 7 As shown, the thickness of the discharge section 110 is D1, and the thickness of the mounting section 120 is D2, where D1 < D2. The elastic membrane 100 has a disc-shaped structure. A ring of mounting sections 120 is provided circumferentially on the outer side of the discharge section 110. A ring of mounting holes 121 is provided on the mounting section 120. Multiple discharge channels 111 are provided on the discharge section 110, and the mounting holes 121 are located outside the discharge channels 111. After assembly, the mounting section 120 is clamped between the base 200 and the stop block 211. Because the thickness of the mounting section 120 is greater than that of the discharge section 110, the technical problem of easy tearing when the elastic membrane 100 is too thin and unfavorable for discharge when the elastic membrane 100 is too thick is solved. Therefore, this elastic membrane 100 can facilitate discharge and effectively prevent tearing, possessing very strong practical performance.

[0041] like Figure 7 As shown, the upper surface of the discharge section 110 is flush with the upper surface of the mounting section 120, and the lower surface of the discharge section 110 is recessed into the lower surface of the mounting section 120. This reduces the bending points of the elastic membrane 100, facilitates the installation of the elastic membrane 100, and improves the strength of the elastic membrane 100.

[0042] like Figure 2 and Figure 8 As shown, a flange 220 is provided on the base 200, which extends along the axial direction of the base 200. The elastic membrane 100 is placed inside the flange 220. The flange 220 and the hot-melt column 210 are located on the same side of the base 200. The mounting part 120 is placed inside the base 200, and the flange 220 wraps around the mounting part 120 on the inside, thereby improving the overall installation strength of the elastic membrane assembly.

[0043] Example 2: As Figure 11As shown, a material container includes an elastic membrane assembly, a cover assembly 300, and a bottom assembly 400. The elastic membrane assembly is detachably installed in the bottom assembly 400, and the cover assembly 300 seals and covers the bottom assembly 400. By detachably installing the elastic membrane assembly inside the bottom assembly 400, when there is residual material inside the bottom assembly 400, the elastic membrane assembly can be removed, and the residual material can be reused, reducing material waste.

[0044] In embodiment 2, the bottom assembly 400 includes an outer bottom 420 and an inner bottom 410 fixedly installed inside the outer bottom 420, and the elastic membrane assembly is detachably installed in the inner bottom 410. The cover assembly 300 covers the inner bottom 410, and the cover assembly 300 and the outer bottom 420 are engaged and fixed by a snap-fit ​​assembly.

[0045] Example 3: As Figure 12-13 As shown, in this embodiment, the bottom assembly 400 includes an outer bottom 420, and the base 200 also includes a locking portion 230. The locking portion 230 is fitted onto the opening of the outer bottom 420, and the locking portion 230 and the outer bottom 420 are locked together and fixed. The elastic membrane assembly is snapped onto the opening of the outer bottom 420 through the locking portion 230, and the cover assembly 300 is screwed to the outer bottom 420. The locking portion 230 extends along the radial direction of the base 200, and the locking portion 230 and the protrusion 220 are located on both sides of the base 200, respectively. A groove is formed in the locking portion 230, and the opening of the outer bottom 420 is inserted into the groove. Optionally, a slot 231 is formed on the inner side of the engaging portion 230, and a protrusion 421 is provided on the outer side of the opening of the outer bottom 420. When the engaging portion 230 is fitted onto the outer bottom 420, the protrusion 421 engages into the slot 231, thereby detachably installing the elastic membrane assembly onto the outer bottom 420. Of course, in other embodiments, the engaging portion 230 is provided with a protrusion, and the outer side wall of the outer bottom 420 is provided with a slot, which also achieves the purpose of fixing the elastic membrane assembly onto the outer bottom 620.

[0046] It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the scope of protection of this patent application shall be determined by the appended claims.
