A granular medicine protecting packaging bag

Abstract

A protective packaging bag for granular medicines, relating to the field of granular medicine packaging bags, includes two square PET plastic films. The edges of the two square PET plastic films are heat-pressed to form heat-pressed edges. A connecting strip is fixed to the lower end of the middle of the upper heat-pressed edge. A conical film is fixed below the connecting strip, and a corrugated film is formed below the conical film. Tear openings are symmetrically provided on the left and right sides of the heat-pressed edges near the upper end. This invention, through the conical film set inside the packaging bag made of two PET plastic films via the connecting strip, ensures that the tear from the tear opening can only extend upwards along the edge of the conical film. Rotating the upper heat-pressed edge allows the two tear openings to converge. The upper heat-pressed edge can be completely separated from the packaging bag made of two PET plastic films without requiring much force. The tearing and separation does not cause shaking. Combined with the blocking effect of the corrugated film, this prevents the medicine particles from spilling out when the packaging bag is torn open.

Description

Technical Field

[0001] This invention relates to the field of granular pharmaceutical packaging bags, and in particular to a protective packaging bag for granular pharmaceuticals. Background Technology

[0002] To facilitate dissolving and taking medications, many drugs are made into loose granules. These medications are typically packaged in bags made by heat-pressing the edges of two square PET plastic films together. For easy opening, slits are usually cut on both sides of the bag, allowing users to easily tear it open. However, because the tearing begins at the heat-pressed edge, the bags separate into two non-adhesive layers in the middle. When tearing the other heat-pressed section, the tear marks on the two PET plastic layers don't align, making it difficult to easily tear the other edge. Incomplete tearing obstructs the pouring process, while complete tearing requires considerable force, causing the bag to vibrate and scatter the granules, making it very inconvenient to use. Furthermore, due to the loose texture of the granules, powder is generated during transportation due to collisions and friction. When the user tears open the bag, this fine powder flies everywhere, causing discomfort. Also, when patients take half a packet of medication as prescribed, it's easy to misjudge the tilting angle when pouring, resulting in pouring too much. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, this invention discloses a protective packaging bag for granular medicines. This invention utilizes a conical membrane connected by a connecting strip inside the packaging bag made of two PET plastic films. This ensures that the tear from the tear point extends only upwards along the edge of the conical membrane. Rotating the upper hot-pressing edge allows the two tear points to converge. A small amount of force is required to completely separate the upper hot-pressing edge from the two PET plastic films, preventing shaking during tearing. The corrugated membrane also acts as a stopper, preventing medicine particles from spilling out when the packaging bag is torn. Pulling out the corrugated membrane allows for precise control of the dispensing amount, avoiding excessive discharge caused by tilting the upper opening of the PET plastic film too downwards when dispensing granular medicine. The corrugated membrane also absorbs the kinetic energy of the granular medicine during transport, keeping the granules separated and preventing them from rubbing against each other and generating dust, thus preventing powder from flying out when the packaging bag is torn.

[0004] To achieve the aforementioned objective, the present invention employs the following technical solution:

[0005] A protective packaging bag for granular medicine includes two square PET plastic films. The edges of the two square PET plastic films are heat-pressed and formed with heat-pressed edges. A connecting strip is fixed to the lower end of the middle of the upper heat-pressed edge. A conical film is fixed below the connecting strip. A corrugated film is formed below the conical film. Tear openings are symmetrically opened on the left and right sides near the upper end of the heat-pressed edges.

[0006] A conical film is an isosceles triangle with its base at the bottom and its width equal to that of the PET plastic film in the left-right direction.

[0007] The two tear lines intersect below the hot-pressed edge above.

[0008] The two tear strips are inclined upwards, and the inclination of the tear strips is the same as the inclination of the waist edges on the left and right sides of the conical membrane. When the connecting strip is extended, the inward extension line of the tear strips coincides with the waist edge of the conical membrane.

[0009] The corrugated film is wavy, and its width in the left and right directions is equal to that of the PET plastic film in the left and right directions.

[0010] The connecting strip is made of relatively soft nylon rope.

[0011] Conical and corrugated films are made from cardboard.

[0012] Due to the adoption of the above technical solution, the present invention has the following beneficial effects:

[0013] The present invention discloses a protective packaging bag for granular medicines. A conical membrane, connected by a connecting strip inside the bag made of two PET plastic films, ensures that the tear from the tear point extends only upwards along the edge of the conical membrane. Rotating the upper hot-pressing edge allows the two tear points to converge. The upper hot-pressing edge can be completely separated from the two PET plastic films without requiring significant force, preventing shaking during tearing. The corrugated membrane also acts as a stopper, preventing spillage of medicine particles when the bag is torn. Pulling out the corrugated membrane allows for precise control of the dispensing amount, avoiding excessive discharge caused by tilting the upper opening of the PET plastic film downwards when dispensing granular medicine. The corrugated membrane also absorbs the kinetic energy of the granular medicine during transport, keeping the particles separated and preventing dust generation from friction and collision when the bag is torn.

[0018] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0019] Combined with appendix Figures 1-3 A protective packaging bag for granular medicine includes two square PET plastic films 1. The edges of the two square PET plastic films 1 are heat-pressed to form heat-pressed edges 2. A connecting strip 4 is fixed to the lower end of the middle of the upper heat-pressed edge 2. A conical film 5 is fixed below the connecting strip 4. A corrugated film 6 is formed below the conical film 5. Tear openings 3 are symmetrically opened on the left and right sides of the heat-pressed edges 2 near the upper end.

[0020] The conical film 5 is an isosceles triangle with its base at the bottom and its width equal to that of the PET plastic film 1 in the left and right directions. The waist of the conical film 5 extends upward, which can guide the tear opening of the tear 3 so that they converge at the top.

[0021] The extension lines of the two tear 3 intersect below the upper hot pressing edge 2 to prevent the two tear 3 from connecting to the upper hot pressing edge 2 before they meet.

[0022] The two tear strips 3 are inclined upwards, and the inclination of the tear strips 3 is the same as the inclination of the waist edges on the left and right sides of the conical membrane 5. When the connecting strip 4 is extended, the extension line of the tear strips 3 to the inward side coincides with the waist edge of the conical membrane 5.

[0023] The corrugated membrane 6 is wavy. Specifically, the crest and bottom lines of the wavy membrane 6 point to the left and right directions. This means that the granular drug can move from the left end to the right end of the corrugated membrane 6 without obstruction. After the corrugated membrane 6 is pulled out of the PET plastic film 1, the granular drug can be discharged without obstruction. The width of the corrugated membrane 6 in the left and right directions is equal to the width of the PET plastic film 1 in the left and right directions.

[0024] Connector 4 is made of relatively soft nylon rope.

[0025] The conical membrane 5 and the corrugated membrane 6 are made of cardboard.

[0026] In this type of protective packaging bag for granular medicine, when the user needs to open the heat-sealed edge 2, they can tear inward along the tear 3. The tear 3 is inclined upward and overlaps with the two sides of the conical film 5. The conical film 5 does not have tear 3 and is not subject to tearing force. The tear 3 on the PET plastic film 1 on the front and back sides of the conical film 5 gradually extends inward as the user operates. The torn part of the PET plastic film 1 bends forward or backward, and the bent part is limited by the conical film 5. Therefore, the tear 3 can only extend inward and upward along the inclined direction of the left and right sides of the conical film 5. After the user extends both tear 3 to the middle of the PET plastic film 1 by tearing, the user holds the upper heat-sealed edge 2 with one hand and the conical film 5 with the other hand, causing the conical film 5 and the upper heat-sealed edge 2 to rotate relative to each other by half a turn. The tear 3 on film 1 can be joined together, and the upper hot-pressed edge 2 can be separated from PET plastic film 1. Then, the user holds PET plastic film 1 with one hand to tilt it, and holds the upper hot-pressed edge 2 with the other hand to pull the conical film 5 outward through the connecting strip 4. The conical film 5 drives the corrugated film 6 to move outward, which in turn drives the granular medicine in the corrugated film 6 to move outward. The granular medicine in the corrugated film 6 that has moved outside PET plastic film 1 can automatically fall to the designated position under the action of gravity. This will prevent the situation where the packaging bag is torn open and the tilt angle is too large and the medicine is poured out in excess. During transportation, the corrugated film 6 can separate the granular medicine as much as possible to avoid them colliding and rubbing against each other. On the other hand, it can absorb the kinetic energy of the granular medicine when it vibrates, so as to avoid the generation of more medicine powder, which will fly when torn and cause inconvenience to the patient's nose and eyes.

[0027] The parts of this invention not described in detail are prior art. Although the invention has been specifically shown and introduced in conjunction with preferred embodiments, there are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of the invention. However, those skilled in the art should understand that various changes in form and detail can be made to the invention without departing from the spirit and scope of the invention as defined in the appended claims, and all such changes are within the scope of protection of the invention.
