Description

Technical Field

[0001] The utility model relates to the technical field of blister packaging, in particular to an extruded capsule-type fluid double blister packaging. Background Art

[0002] Fluid packaging is a packaging method specifically designed for liquid and semi-liquid substances. It is widely used in industries such as food, beverages, pharmaceuticals, and chemicals. Its key features lie in its sealing, barrier properties, and physical protection capabilities. Because fluids are inherently susceptible to environmental influences, packaging materials must possess excellent gas and moisture barrier properties to prevent product deterioration. Therefore, polymers such as barrier plastics are commonly used in fluid packaging.

[0003] Traditional fluid packaging usually uses bottles, bags or other containers to store and transport fluids, while blister packaging uses plastic or composite materials to directly form containers, sealing the fluid or semi-fluid inside. This often takes up more space, especially for bottled liquids, which are difficult to flexibly adjust in shape due to their rigidity. On the other hand, traditional plastic packaging also brings certain environmental problems. With increasingly stringent environmental protection requirements, lightweight design and the use of recyclable materials are an important direction for the development of fluid packaging technology. Therefore, some biodegradable materials have begun to be used in recent years. However, due to their high cost and inferior base material performance to traditional materials, they are difficult to promote on a large scale in the short term. At the same time, while ensuring product safety, manufacturers also hope to improve economic benefits by reducing material costs. Therefore, lightweight packaging design is more advantageous at present.

[0004] Compared to traditional fluid packaging, fluid blister packaging has significant structural and performance differences. As a relatively advanced packaging technology, fluid blister packaging is widely used in the pharmaceutical, food, cosmetics, and other fields. It offers significant advantages in precise dosage control, sealing, and convenience. The hallmark of fluid blister packaging lies in its concave-convex structure, which not only helps reduce packaging volume but also provides better protection during transportation and storage. In terms of sealing and protection, fluid blister packaging typically utilizes heat sealing or welding technology, which provides a more reliable seal and effectively prevents the intrusion of external factors such as oxygen and moisture, thereby extending the shelf life of the product.

[0005] The existing fluid blister packaging mainly uses a single-sided blister and a backing plate or heat-sealed film to form an enclosed space to store the fluid, ensuring that the fluid is well sealed and remains stable within the package. However, since the opening surface of the blister requires a heat-sealed plastic film or backing plate, the sealing strength of the plastic film or backing plate is affected by the quality of the material and the heat-sealing temperature. If improperly controlled, the sealing strength may be insufficient, resulting in fluid leakage or package damage. Secondly, the heat-sealed area is prone to uneven heating, resulting in weak points on the sealed edge, which in turn affects the overall reliability of the package. In addition, packaging with this structure is more inconvenient to open during use, and may require the use of scissors or other tools, affecting the consumer's user experience.

[0006] In view of this, there is an urgent need to develop a fluid blister package that is small in size, lightweight, well-sealed, portable and easy to open to solve the above-mentioned defects. Summary of the Invention

[0007] The purpose of the present utility model is to provide a double blister package of squeezed capsule-type fluid, which adopts two blisters to be abutted and sealed by heat sealing or other processes to form a capsule body shape, and forms a fluid outlet at one end of the capsule body to facilitate opening the package and taking the fluid, so as to solve the problems raised in the above-mentioned background technology.

[0008] In order to solve the above technical problems, the technical solutions provided by the present invention are as follows:

[0009] A squeeze capsule type fluid double blister package, comprising:

[0010] The capsule cavity is formed by combining two single-sided blister packs formed by blistering the sheet material according to the designed shape and then sealing them through a sealing process;

[0011] a drainage portion, one end of which is in communication with the interior of the capsule cavity and the other end of which extends outward;

[0012] The sealing portion extends outward along the outer extension of the capsule cavity and the drainage portion to seal the capsule cavity and the drainage portion inside.

[0013] Furthermore, the contact areas of the two single-sided blister caps of the capsule cavity have the same shape, and the convex shapes and heights of the non-contact areas of the two single-sided blister caps may be inconsistent.

[0014] Furthermore, the drainage portion is a tubular body formed by joining two single-sided blister protrusions formed by blister forming and sealing them together, or a flat water hose body through which fluid can flow formed by joining sheets and sealing them together.

[0015] Furthermore, the sealing portion is sealed by one of a heat sealing process, an ultrasonic sealing process, a laser sealing process and an adhesive sealing process.

[0016] Furthermore, the squeeze capsule type fluid double blister package further comprises an easy tearing opening, wherein the easy tearing opening is away from the capsule cavity, and the drainage portion is cut into two sections after the easy tearing opening is torn.

[0017] The beneficial effects of the utility model are:

[0018] The utility model forms a double-blister capsule cavity by abutting two single-sided blister caps and sealing them through a sealing process, and a drainage portion is formed at one end of the capsule cavity. A small dose of the fluid to be packaged is quantitatively injected into the capsule cavity and then the drainage portion is sealed, thus forming the squeezed capsule-type fluid double-blister package of the present application. After the drainage portion is cut or torn along the easy-tear notch, when the capsule cavity is squeezed, the packaged fluid can all enter the desired position along the drainage portion at one time. The utility model is simple to operate, portable and easy to open, easy to adjust the appearance, and easy to be produced on a large scale. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods. Example 1

[0035] like Figure 1-Figure 5 As shown, this embodiment discloses a squeeze capsule type fluid double blister package, comprising:

[0036] The capsule cavity 4 is formed by combining two single-sided blister caps 3 formed by blistering the sheet 1 according to the designed shape and then sealing them together through a sealing process. When combining, the two single-sided blister caps 3 are folded in half along the pressed combining line so that the contact areas of the two single-sided blister caps 3 are attached together.

[0037] a drainage portion 5, one end of which is connected to the interior of the capsule cavity 4 and the other end of which extends outward;

[0038] Seal, 6, the sealing portion 6 extends outward along the outer extension of the capsule cavity 4 and the drainage portion 5 to seal the capsule cavity 4 and the drainage portion 5 inside.

[0039] It should be noted that the contact areas of the two single-sided blister caps 3 of the capsule cavity 4 are consistent in shape, and the contact area here is the outer edge of the opening of the single-sided blister cap 3. If the outer edge shapes of the two single-sided blister caps 3 are inconsistent, it will be unsightly when they are sealed together. The convex shapes and heights of the non-contact areas of the two single-sided blister caps 3 may be inconsistent. The non-contact area is mainly the convex structure part of the single-sided blister cap 3. When the convex shape of the non-contact area is consistent with the height, the formed capsule cavity 4 has symmetry, but the appearance shape of the shape is limited. When the convex shape of the non-contact area is inconsistent with the height, the formed capsule cavity 4 can have more appearance shapes and higher adjustability.

[0040] The drainage portion 5 in this embodiment is a flat water belt body through which fluid can pass, which is formed by sealing the sheets after they are matched. For example, a sheet with a thickness of 0.05 mm to 0.2 mm is used. In this embodiment, a composite sheet with a thickness of 0.1 mm is used. After its two sides are sealed into a relatively narrow and long flat water belt, when the fluid with low viscosity packaged in the capsule cavity 4 is squeezed hard, such as water, soy sauce, vinegar, aqueous solution, olive oil, etc., such fluid is squeezed toward the flat water belt-shaped drainage portion 5 under the extrusion pressure, and the drainage portion 5 forms a certain tubular deformation, so that the fluid in the package flows out smoothly, such as Figure 5 The figure shows a schematic structural diagram of a flat water belt-shaped drainage portion 5 . In the figure, the two sheets of the drainage portion 5 indicated by the black solid line in the sealing portion 6 are not sealed together.

[0041] The plastic sheet can be sealed using the following sealing processes: heat sealing, ultrasonic sealing, laser sealing, adhesive sealing, etc. In this embodiment, the sealing portion 6 is sealed using the heat sealing process.

[0042] In order to improve the user experience, the squeezed capsule type fluid double blister package of this embodiment further includes an easy tearing opening 7, which is away from the capsule cavity 4, and the easy tearing opening 7 cuts the drainage portion 5 into two sections after being torn. Figure 4 As shown, in the molding process of the fluid double blister package of the present application, a region wide at both ends and narrow in the middle is die-cut along one side of the drainage portion 5, and two easy-tear notches 7 are die-cut along the edge of the narrowest portion. The easy-tear notches 7 do not cut into the drainage portion 5 during molding, thereby ensuring the sealing of the entire fluid double blister package. If user experience is not a consideration, or there are other special requirements for packaging sealing that do not require notches, the easy-tear notches 7 can be omitted during molding of the fluid double blister package of the present application, and the drainage portion 5 can be cut with scissors during use. Example 2

[0043] like Figures 6-10 As shown, this embodiment differs from Example 1 in that the drainage portion 5 is formed by a tubular body formed by two single-sided blister-molded protrusions that are then sealed together. The drainage portion 5 in this embodiment requires simultaneous blistering to ensure that the contents of the package are not squeezed out, causing significant inconvenience. Furthermore, low-viscosity fluids are also difficult to squeeze out of thick sheets of 0.2mm to 1mm thick. Therefore, the 0.3mm thick composite sheet used in this embodiment requires a pre-blistered protrusion structure, which is then sealed together to form a tubular drainage portion 5, allowing for smooth extrusion of the high-viscosity fluids and semi-fluids contained within the package. All other aspects of this embodiment remain consistent with Example 1.

[0044] The above embodiments merely illustrate the basic principles and features of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications are possible without departing from the spirit and scope of the present invention. Such changes and modifications are within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
