Abstract

The utility model relates to a pharmaceutical packaging container, in particular to cardboard boxes for packaging tablets, capsules, granules, ampoules and other types of medicinal products. The cardboard pharmaceutical packaging container is configured as a box, comprises opposite-disposed closing outer joints 6 provided with relief embossing forming, on the surface of the joints 6, longitudinal convex elements 7 oriented parallel to the direction of the cardboard fibers, said relief embossing occupying at least 80% of the surface of the closing joint 6. The utility model allows to reduce the bending ability of the closing joints of the cardboard packaging container while not significantly increasing the material costs for the production of the packaging container thanks to the functional reinforcement of the material of the packaging container joints and the reduction of the stresses occurring therein.

Description

Cardboard pharmaceutical packaging containers

The invention relates to a pharmaceutical packaging container for pharmaceutical products, in particular to cardboard boxes for packaging tablets, capsules, granules, ampoules and other types of pharmaceutical products.

The prior art provides a pharmaceutical packaging container, which is constructed as a cardboard box and includes oppositely arranged closing joints consisting of an inner joint and an outer joint (see, for example, https://yarus-market.ru/upakovka-pod-meditsinu/kartonnaya -upakovka-dlya-mediciny-i-farmacevtiki/ farmacevticheskaya-korobka-pachka). A disadvantage of known packaging containers is the arching bending of the outer closing joints due to the presence of stresses in the cardboard caused by unevenly distributed loads along the folding and gluing zones. Mechanical impact on packaging containers, for example during transport and long-term storage, can lead to multiplied stresses. Additionally, the arching of the outer closure joint may be due to temperature changes caused by the natural expansion/compression of the packaging container material. The arched curvature of the outer closure joint may allow dust and moisture to enter through gaps created inside the packaging container, and may make the box less stable on flat surfaces when the joints are provided at the top and bottom of the box. Additionally, in some cases, gaps created by bent joints allow tamper protection to be bypassed, as discussed below: One can maneuver a ruler through the gap and gently bend the joint lock while maintaining the integrity of the packaging container . In the case of a box size of 110x110x50 (mm), the size of the protrusion at the upper end point of the curved external joint is on average 1.5 to 4 mm. In addition, further strengthening the outer closure joint of the packaging container by layering strengthening elements will significantly increase the product cost, complicate the manufacturing process, and reduce the production speed.

The purpose of this creation is to reduce the bending capacity of the external closure joint of a pharmaceutical packaging container without significantly increasing the material cost of the packaging container. The technical achievement is the functional strengthening of the material of the external closing joint of the packaging container and the reduction of the stress present in the joint. The technical result is achieved by the fact that in a cardboard pharmaceutical packaging container constructed as a box including an oppositely arranged closing joint consisting of an inner joint and an outer joint, the outer joint is provided with a relief embossing, thus forming a longitudinal pattern on the surface of the joint Raised elements. The relief embossing preferably occupies at least 80% of the joint surface, and the longitudinal raised elements formed by the relief embossing are preferably oriented parallel to the direction of the paperboard fibers. Functional reinforcement of the material of the closing joint is achieved by providing the outer closing joint with a relief embossing, thus forming on its surface longitudinal raised elements that act as reinforcements. Reinforcements placed on the surface of a closed joint relieve stress in the material. Furthermore, no additional material is required to reinforce the closed joint and only the properties of the cardboard itself are utilized. By providing relief embossing over more than 80% of the area of the closed joint, an even distribution of the reinforcement over most of the joint surface is ensured, thereby strengthening the joint overall. The torsional stiffness of the joint is further increased by orienting the raised elements formed by the relief embossing parallel to the direction of the cardboard fibers.

The cardboard pharmaceutical packaging container is configured as a box with a parallelogram shape and includes sides 1 , 2 , 3 , 4 and an oppositely arranged closing joint consisting of an inner joint 5 and an outer joint 6 . The outer joints 6 are provided with relief embossings which form longitudinal raised elements 7 on the surface of these joints. Furthermore, the relief embossing can form a raised element 8, which is a window for printing variable data, such as data matrix codes, batch numbers, production dates, etc. The relief embossing occupies at least 80% of the closed surface of each external joint 6 . The longitudinal elements 7 are oriented parallel to the direction of the cardboard fibers. The closing joints 5 and 6 can be provided both at the top and bottom of the box (see Figures 1, 2, 3), and on opposite sides of the box (see Figure). The elements 7 and 8 formed by relief embossing protrude above the surface of the cardboard by at most 1/2 of the thickness of the cardboard used. The height of the protrusions formed by the elements 7, 8 and the distance between the longitudinal elements 7 are chosen according to the density of the cardboard used. The longitudinal elements 7 distributed over the surface of the joint 6 allow to relieve the material stresses exerted on the joint 6, increasing the stiffness of these elements and thus preventing them from buckling. Furthermore, the width of the longitudinal elements 7 can be different. Closing joints can be provided both at the top and bottom of the box (see Figure 2), functioning as bottom and top lids of the packaging container, and on opposite sides of the box (see Figure 3). When the closing joints 6 are provided at the top and bottom of the packaging container, the relief embossing applied to the closing joints increases the stability of the package on the surface and prevents the box from slipping off inclined surfaces. To demonstrate the effectiveness of using relief embossing to prevent joint bending of cardboard packaging containers made from the same SimWhite cardboard with a density of 300 g/m, two batches of boxes of the same design and size intended for packaging pharmaceutical products were produced . In one of these batches, the closing joints of the boxes were provided with relief embossing, which formed raised longitudinal reinforcing elements. On one of the closing joints, in addition to the longitudinal raised elements, raised elements for the information seal are also provided by relief embossing. Relief embossing is provided on 80% of the area of each closed joint. In the second batch of boxes, the closing joints remain smooth with no relief embossing. According to the results of the study, boxes provided with relief embossing on the joints showed an average reduction in the arching bend of the joints of 1 to 2.5 mm. 10 sample boxes were used as samples and the results were stable for all samples. The present invention therefore makes it possible to improve the consumer characteristics of paperboard pharmaceutical packaging containers by significantly reducing the possibility of arching of the outer closure joint.
