[0002] The hose is the most widely used packaging material in daily life because of its convenience, variety of forms and low cost. Among them, extrusion products such as facial cleanser, hand cream, eye cream, toothpaste, etc. are the most commonly used. Existing packaging hoses are usually single, with only a single property, a single function or a single flavor. Consumers can only choose to buy and use products with a single function. Therefore, double-ended packaging hoses are more suitable for market needs. Double-ended packaging hoses are specially designed packaging hoses with two independent outlets, each of which is filled with different products.

[0003] For example, a double-ended toothpaste tube is usually divided into two parts, each with an independent cap and squeezing device. The toothpaste in each outlet can be selected according to personal needs. Common combinations include cleaning toothpaste and whitening toothpaste, or anti-caries toothpaste and sensitive toothpaste.

[0004] Chinese utility model patent CN220925015U discloses a double-headed toothpaste tube for convenient extrusion, which includes a connecting block, both sides of which are fixedly provided with toothpaste tube bodies, the outer ends of one side of the two toothpaste tube bodies are slidably provided with extrusion blocks, the middle part of one side of the two extrusion blocks is provided with a fixed groove, both sides of the two ends of the two fixed grooves are provided with slide grooves, one side of the two toothpaste tube bodies is fixedly provided with an extrusion head, one side of the two extrusion heads is fixedly provided with an extrusion tube, and both ends of the two toothpaste tube bodies are fixedly provided with a pair of slide rails; however, this solution increases the difficulty of producing the toothpaste tube by arranging the slide rails on the surface of the tube body, and increases the production cost. At the same time, since the size of the fixed groove of the extrusion block is fixed, there will still be a lot of toothpaste residue in the toothpaste tube that cannot be squeezed out by the extrusion block, and the technical problem of toothpaste residue cannot be solved well.

For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following text, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0024] Example 1

[0025] like Figure 1 As shown, the dual-purpose dual-function packaging hose of this embodiment includes a first tube body 1 and a second tube body 2 fixedly connected together at the tail end; the top ends of the first tube body 1 and the second tube body 2 both include an extrusion head 3 and a cover body 4 arranged on the extrusion head 3, and the tail end opposite to the extrusion head 3 is sealed; an extrusion device 5 is arranged at the tail end of the first tube body 1 and the second tube body 2, and the extrusion device 5 includes a base 51 fixedly arranged at the tail end of the first tube body 1 and the second tube body 2, and the base 51 is connected to an extrusion block 52 on both sides of the first tube body 1 or the second tube body 2 through an elastic band 6; the extrusion block 52 can move toward the extrusion head 3 of the first tube body 1 or the second tube body 2 to extrude the substance packaged inside the first tube body 1 or the second tube body 2.

[0026] A through hole 521 for accommodating the first tube body 1 and the second tube body 2 is opened in the middle of the extrusion block 52; a scraper 53 for adjusting the size of the passing gap of the through hole 521 is arranged in the through hole 521; a guide hole 522 for the scraper 53 to move is opened on the extrusion block 52, and an elastic member 54 is arranged between the scraper 53 and the extrusion block 52.

[0027] The elastic member 54 causes the scraper 53 to move toward the first tube body or the second tube body; the scrapers 53 are provided on both sides of the extrusion block 52 facing the packaging hose; the side of the scraper 53 away from the packaging hose is provided with a guide rod 55 partially located in the guide hole 522, and the end of the guide rod 55 located outside the guide hole 522 is provided with a pressing plate 56, and the elastic member 54 is provided between the pressing plate 56 and the outer wall of the extrusion block 52. The two scrapers arranged opposite to each other can increase the extrusion effect of the residual material in the packaging hose and apply greater pressure to the first tube body 1 or the second tube body 2.

[0028] A plurality of positioning posts 7 are provided on the side of the base 51 facing the extrusion block 52, and a positioning hole 8 matching the positioning posts 7 is provided on the side of the extrusion block 52 facing the base 51; the base 1 and the extrusion block 52 are connected by a plurality of elastic bands 6; in order to prevent the residue of the material in the packaging hose, the length of the scraper 53 is greater than the size of the widest part of the packaging hose.

[0029] Example 2

[0030] Different from the first embodiment, the side walls of the first tube body 1 and the second tube body 2 of the present embodiment are fixedly connected, the extrusion block 52 is arranged on the side of the base 51 facing the first tube body 1 and the second tube body 2, and one extrusion block 52 is arranged on each of the first tube body 1 and the second tube body 2; in order to prevent the extrusion block 52 from interfering with the part where the first tube body 1 and the second tube body 2 are connected, a clearance groove 8 is provided on one side of the extrusion block 52 located at the connection between the first tube body 1 and the second tube body 2. The elastic member 54 in both the first embodiment and the second embodiment is a tension spring.

[0031] The operation method of Example 1 is the same as that of Example 2. When the consumer needs to squeeze out the substance in the first tube body 1 or the second tube body 2, the consumer only needs to move the extrusion block 52 from the tail end of the first tube body 1 or the second tube body 2 toward the extrusion head 3. At the same time, the consumer can use fingers to pinch the pressure plates 56 located on both sides of the extrusion block 52. Under the pressure of both hands, the two scrapers 53 respectively approach the middle of the through hole 521 of the extrusion block 52, thereby reducing the passing gap of the through hole 521, so that the residual substance in the first tube body 1 or the second tube body 2 is subjected to greater pressure and is pushed out of the packaging hose by the scraper 53. When the squeezing block 52 is pushed upward, the elastic band 6 between the squeezing block 52 and the base 51 can stabilize the movement trajectory of the squeezing block 52. When use is completed, the squeezing block 52 will automatically shrink to the base 51 under the drive of the contraction force of the elastic band 6, and be stuck on the positioning column 7 of the base 51 to prevent the squeezing block 52 from sliding around and also prevent the squeezing block 52 from being lost, making it convenient for consumers to carry it. Each time it is used, it is squeezed upward from the bottom of the packaging hose to prevent the material in the tube from remaining at the bottom of the packaging hose for a long time, thereby increasing the convenience of use.

[0032] The one-tube dual-purpose dual-function hose consists of a tube body, two tube shoulders, two tube nozzles, two sealing pieces and two caps. The patented production process of the one-tube dual-purpose dual-function hose packaging technology is as follows: composite material coil → cutting and coiling the tube according to the design size → welding the side seam of the tube body with high frequency or hot stamping technology → implementing photoelectric control tube cutting according to the design length requirement of the one-tube dual-purpose dual-function hose → using high frequency or hot stamping technology to separate the tube body space in the middle section of the tube body to form two connected but unconnected spaces → combining the two ends of the tube body with two pre-made tube shoulders → respectively welding the tube body and the tube shoulders at both ends with high frequency to form their own outlets → screwing the two outlets with the pre-made tube caps to form a complete set of one-tube dual-purpose dual-function hose packaging, and installing the manufactured extrusion device before welding the tube bodies at both ends. Each different single space of the packaging hose of this embodiment has an outlet and a cap respectively, and the top of the cap (open type, flip type, spiral type, squeeze type, pump pressure type, etc.) is flat, and the flat top area of ​​the cap is wide, which is convenient for the product to be placed upright and stably.

[0033] Production equipment:

[0034] Common composite hose making machines are mainly of two types: AISA and Packets Global.

[0035] ① Use AISA tube making machine, which is suitable for aluminum-plastic and all-plastic composite materials. The tube body is formed by high-frequency welding, cut into the required tube length, and then high-frequency welded with the pre-injection-molded shoulder piece to form a tube;

[0036] ②Packers Global pipe making machine is used, which is suitable for aluminum-plastic and all-plastic composite materials. The pipe body is formed by high-frequency or hot-stamping welding, and then directly injected into the injection molding machine to form the pipe shoulder.

[0037] The above common hose production equipment is usually used to produce single-function hose packaging. A one-tube dual-purpose dual-function hose packaging only needs to be slightly improved on the above common equipment, adding a high-frequency or hot-scalding process for spatial separation in the middle section of the tube body, so that a one-tube dual-function hose with an extrusion device packaging product can be successfully produced. The dual-purpose dual-function packaging hose of this embodiment can be applied to the packaging of various liquid, semi-liquid, semi-solid creams, emulsions, water-based, gels, oils, powders, mud-like, wax-based, freeze-dried and other multi-category and variety products.

[0038] The contents explained in the above embodiments should be understood as these embodiments are only used to more clearly illustrate the present invention, and are not used to limit the scope of the present invention.
