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 cardboard pharmaceutical packaging container for pharmaceutical products, which is constructed as a box and includes two inner and two outer (upper and lower) closure joints arranged oppositely (see, for example, https://yarus-market. ru/upakovka-pod-meditsinu/kartonnaya-upakovka-dlya-mediciny-i-farmacevtiki/kartonnaya-korobka-pod-sklejku-dlya-farmacevtiki).

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. In addition, the arching bend of the external closure joint may be caused by the natural expansion/compression of the packaging container material. resulting temperature changes.

Arched bends in the joints may allow dust and moisture to enter the packaging container through the cracks formed and render the box less stable on the surface. Additionally, in some cases, the gap created by the bent closure joint allows bypassing of tamper protection, as discussed below: one can maneuver a ruler through the gap and gently bend the joint lock while keeping the packaging container intact sex. In the case of a box size of 110x110x50 (mm), the size of the protrusion at the upper end point of the bent joint is on average 1.5 to 4mm.

In addition, further strengthening packaging container joints through layered strengthening elements would significantly increase product costs, significantly complicate the manufacturing process, and reduce production speeds.

The purpose of this creation is to reduce the bending capacity of the external closure joint of a cardboard 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 the cardboard pharmaceutical packaging container is constructed as a box, which consists of two inner and two outer (upper and lower) closing joints arranged opposite each other, the upper outer closing joints are manufactured with relief embossing, so that on the joints Longitudinal raised elements are formed on the surface. 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.

Additionally, the upper external closure joint may be configured to have a length equal to or shorter than the length of the lower external closure joint, wherein a portion of the lower external closure joint not covered by the upper external closure joint is configured to have a relief pressure. Flowers, which form longitudinal raised elements on the surface of the lower outer closing joint, these elements being preferably oriented parallel to the direction of the cardboard fibers. The ratio of joint lengths can depend on package size, board machine characteristics, paper density, adhesion of different types of glue (glue manufacturer).

A functional reinforcement of the material of the upper external closure joint is achieved by providing it with a relief embossing, thereby forming on its surface longitudinal raised elements that act as reinforcements. Reinforcements provided on the surfaces of the upper and lower external closure joints relieve stresses in the material. Furthermore, no additional materials are required to reinforce the upper and lower external closure joints, and only the properties of the cardboard itself are utilized.

By embossing more than 80% of the area of the upper outer closed joint, the reinforcement is ensured to be evenly distributed over most of the joint surface, thus 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.

When the upper outer closure joint is constructed with a shorter length, relief embossing is provided on the lower outer closure joint in the portion not overlapped by the upper outer closure joint, ensuring distribution of the reinforcement through the outer closure joint over the entire box closure area , thereby reducing the stress exerted on the material and functionally strengthening the material.

This creation will be explained by means of the accompanying drawings, of which, [Fig. 1] shows the layout of the subject pharmaceutical packaging container with the external closing joints intended to be glued; [Fig. 2] shows the finished product made using the layout shown in Fig. 1 General view of the box; [Fig. 3] showing the layout for the subject pharmaceutical packaging container having an upper external closure joint of shorter length and disposed on different sides of the box; [Fig. 4 ] shows an overall view of a finished box made using the layout shown in Figure 3; [Figure 5] shows a layout for the subject pharmaceutical packaging container having an upper external closure joint with a shorter length and set on the same side of the box.

Pharmaceutical packaging containers for medicinal products are made of paperboard and constructed as a box having a parallelogram shape and comprising sides 1, 2, 3, 4 and closing joints provided on opposite sides, consisting of on each side It consists of two internal closed joints 5 and two external closed joints (lower external closed joint 6 and upper external closed joint 7). The upper external closure joints may be constructed to have the same length as the lower external closure joints 6 (see Figures 1, 2), or they may be constructed to have a shorter length such that the upper external closure joints cover only a portion of the lower external closure joints 6 (Figure 3, Figure 4, Figure 5). The upper outer closing joint 7 is constructed with relief embossing, thus forming longitudinal raised elements 8 on its surface. Furthermore, the relief embossing can form a raised element 9, which is a window for printing variable data, such as data matrix codes, batch numbers, production dates, etc. The relief embossing occupies at least a portion of the closing surface of the upper outer closing joint 7 80%. The longitudinal raised elements 8 are oriented parallel to the direction of the cardboard fibers.

In the case of implementing an upper outer closing joint 7 with a shorter length, the lower outer closing joint 6 is also provided with relief embossing in the parts not covered by the upper outer closing joint 7 to form longitudinal raised elements 8 . In this case, the raised element 9 as a window for printing variable data can also be configured on the lower outer closing joint 6 .

The inner closing joint 5, the lower outer closing joint 6 and the upper outer closing joint 7 can be provided both on the top and bottom of the box (see Figure 2), and on the opposite sides of the box (see Figure 4) .

The longitudinal raised elements 8 and 9 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 longitudinal protruding elements 8 and 9 and the distance between the longitudinal protruding elements 8 are chosen according to the density of the cardboard used.

The use of relief embossing on the upper outer closing joint 7 and, when the upper outer closing joint 7 has a shorter length, the use of relief embossing on a portion of the lower outer closing joint 6 can increase the stability of the packaging container on the surface, and Prevents the box from sliding off sloping surfaces.

Longitudinal raised elements 8 distributed over the surface of the upper outer closing joint 7 and on a portion of the lower outer closing joint 6 allow relief to be applied to the joint material when the upper outer closing joint 7 has a shorter length stress, increasing the stiffness of these elements and thus preventing them from bending. Furthermore, the width of the longitudinal raised elements 8 can be different.

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 property, four batches of identically sized boxes intended for packaging pharmaceutical products were produced. Structurally, the first two batches of cassettes were constructed with the upper and lower outer closure joints having the same length, and the other two batches of cassettes were constructed with the upper outer closure joint having a shorter length. In the boxes of one of the first two batches, the upper outer closing joint was constructed with relief embossing, which formed longitudinal raised elements 8 . On one of the upper outer closing joints, in addition to the longitudinal protruding elements 8 , a protruding element 9 is provided. Relief embossing is provided on 80% of the area of each upper outer closure joint 7 . In another batch of boxes with the same design, the outer closure joints remain smooth with no embossed embossing.

In the other two batches of boxes with upper external closing joints having shorter lengths, one batch was also provided with relief parts on the upper and lower external closing joints, and the other batch was provided with no relief Embossed smooth exterior closure joint.

According to the research results, relief embossing is provided for the outer closing joint (including the following two situations: only embossing is provided on the upper outer closing joint when the lengths of the upper outer closing joint and the lower outer closing joint are equal, and Batches of boxes with relief embossing for part of the lower outer closed joint and the shorter upper joint showed an average reduction in the camber of the joints of 1 to 2 mm. Take 10 sample packs from each batch as samples and the results are stable for all samples.

Therefore, this creation can improve the consumer characteristics of the final packaging container by strengthening the functionality of the material of the external closing joint and reducing the stress existing in the material, and largely eliminates the arc-shaped bending of the closing joint. possibility.
