Packaging of a hygiene product

Abstract

A packaging body for a hygiene product includes a packaging sheet with at least two tear-off segments extending along a first direction. The size of each tear-off segment in the first direction is equal to the size of the packaging sheet in the first direction. Each tear-off segment includes a main tear-off segment and an auxiliary tear-off segment. The main tear-off segment includes a main cutting portion and a main non-cutting portion, and the auxiliary tear-off segment includes an auxiliary cutting portion and an auxiliary non-cutting portion. When the main non-cutting portion of the main tear-off segment is projected onto the auxiliary cutting portion of the auxiliary tear-off segment in a second direction, the projected portion of the main non-cutting portion of the main tear-off segment completely falls onto the auxiliary cutting portion of the auxiliary tear-off segment. This ensures that the cutting line always passes through a crease, so that when a user tears open the packaging, there is always a tear-off segment providing a cutting line at any position within the tear-off segment area, improving the ease of tearing the packaging.

Description

Technical Field

[0001] This utility model relates to a packaging body for hygiene products, and more particularly to an easy-open packaging body. Background Technology

[0002] In existing technologies, such as Figure 11 The image shows a common packaging design found in daily life. This packaging features an easy-tear line for opening and multiple creases extending in a second direction. Users typically open the easy-tear line through these creases. However, because the easy-tear line consists of alternating cut and non-cut sections, when the packaging sheet with the easy-tear line is folded and sealed to form the bag, the creases may correspond to the non-cut sections of the easy-tear line. In such cases, consumers may find it difficult to open the packaging on the first attempt. Figure 12 Opening the packaging requires finding a new location or using more force, and excessive force may damage the packaging, rendering it unable to hold the contents and causing various inconveniences. Therefore, a packaging design that improves the ease of opening the outer packaging is needed. Utility Model Content

[0003] The main objective of this invention is to overcome the shortcomings of the prior art and provide a packaging body for hygiene products, particularly an easy-to-open packaging body.

[0004] This utility model adopts the following technical solution: a packaging body for hygiene products, the packaging body having a first direction in the same direction as the width direction, a second direction in the same direction as the length direction, and a third direction perpendicular to the first and second directions. The packaging body includes a packaging sheet, which is folded and sealed to form the packaging body. The packaging sheet has the same first and second directions as the packaging body. At least two easy-tear lines extending along the first direction are provided on the packaging sheet of this utility model. The size of the easy-tear line in the first direction is equal to the size of the packaging sheet in the first direction. The easy-tear line includes a main easy-tear line and an auxiliary easy-tear line. The main easy-tear line includes a main cutting part and a main non-cutting part. The auxiliary easy-tear line includes an auxiliary cutting part and an auxiliary non-cutting part. When the main non-cutting part of the main easy-tear line is projected onto the auxiliary cutting part of the auxiliary easy-tear line in the second direction, the projected portion of the main non-cutting part of the main easy-tear line falls completely on the auxiliary cutting part of the auxiliary easy-tear line.

[0005] The above structural design ensures that the cutting line always passes through the crease. When the user tears open the packaging, regardless of which area of ​​the easy-tear line the user applies force to, there will always be an easy-tear line to provide a cutting line, thus improving the ease of tearing open the packaging.

[0006] Furthermore, the main cutting portion of the main easy-tear line segment is a straight line segment, and the size D1 of the first direction of the main cutting portion of the main easy-tear line segment is 0.5mm to 2mm, preferably 1mm to 1.5mm; the size D3 of the first direction of the auxiliary cutting portion of the auxiliary easy-tear line segment is 0.5mm to 2mm, preferably 1mm to 1.5mm; the spacing D5 between two adjacent easy-tear line segments is 0.5mm to 2mm, preferably 1mm.

[0007] By further restricting the configuration and size of the tear-off line, it is ensured that it is easier to tear without effort, while also preventing insects from entering the packaging through the cut line.

[0008] Alternatively, the main cutting portion of the main tear-resistant segment may be non-linear, and may be either arc-shaped or "∧"-shaped.

[0009] Both the arc and the "∧" shape have their sides facing the secondary easy-tear segment. Both of these configurations have the function of guiding the tear line towards the second easy-tear segment when tearing the easy-tear line, preventing the tear line from deviating to the undesirable outer side and improving the tearing effect.

[0010] Furthermore, the size D1 of the first direction of the main cutting portion of the main tear-off line segment is 1mm to 2mm; the size D3 of the first direction of the auxiliary cutting portion of the auxiliary tear-off line segment is 0.5mm to 2mm; and the spacing D6 between two adjacent tear-off lines is 1mm to 2.5mm.

[0011] Furthermore, the size D1 of the first direction of the main cutting portion of the main tear-off line segment is 1.5mm, and the spacing D6 between two adjacent tear-off lines is 1.5mm.

[0012] Based on the improved cutting line setting, the size of the easy-tear line segment is further restricted to ensure that it is easier to tear without effort, while also preventing insects from entering the packaging body 1 through the cutting line.

[0013] Furthermore, the main tear-off line segment and the auxiliary tear-off line segment are parallel to each other.

[0014] Furthermore, the auxiliary easy-tear segment includes a first auxiliary easy-tear segment and a second auxiliary easy-tear segment, and the main easy-tear segment is symmetrical about the first auxiliary easy-tear segment and the second auxiliary easy-tear segment.

[0015] The overall aesthetic appeal is enhanced through a symmetrical design structure.

[0016] Furthermore, when the auxiliary cutting portion is projected onto the main cutting portion in the second direction, the end projection portion of the auxiliary cutting portion falls on the non-end region of the main cutting portion.

[0017] By having the auxiliary cutting section and the main cutting section overlap in a certain area in the second direction, the production error during the production process can be reduced, resulting in the easy-tear section having no cutting part in the longitudinal direction. This ensures that the cutting line will definitely pass through the crease, thus guaranteeing a higher probability of improving the easy-tear effect.

[0018] Furthermore, the packaging body has a sealing portion, and the tear-off line does not overlap with the sealing portion.

[0019] The above settings ensure that the tear line can function properly to open the packaging. Attached Figure Description

[0032] The present invention will be further described below through specific embodiments.

[0033] Define the width direction of the packaging body as the first direction X, the length direction of the packaging body as the second direction Y, and the direction of the packaging body perpendicular to the first and second directions as the third direction Z.

[0034] The “crease” of the packaging: The angle between the tangents of two adjacent surfaces of the crease is between 0° and 180°, excluding the endpoint 180°. The crease may be an arc-shaped transition surface or a fold line. Figure 2 The multiple dashed lines extending in the second direction Y in the middle refer to the crease portion 12, which satisfies the aforementioned description in the actual three-dimensional packaging body.

[0035] The crease area mentioned in this article refers to the non-cut portion of the easy-tear line. This means that when the user tears open the packaging, they pinch the crease and apply force to a point on the crease, which is located on the non-cut portion of the easy-tear line.

[0036] The term "main tear-off segment" mentioned in this article can refer to either a single tear-off segment or multiple tear-off segments. In the implementation examples, only one tear-off segment is included, but the actual implementation is not limited to specific implementation examples.

[0037] This article mentions that "the projection of the main non-cutting portion of the main tear-off line segment completely falls on the auxiliary cutting portion of the auxiliary tear-off line segment." Examples are given below, illustrating the case where there is one main tear-off line segment and one to two auxiliary tear-off line segments: In the first case, there is one main tear-off line segment and one auxiliary tear-off line segment. The main non-cutting portion of the main tear-off line segment is projected onto the auxiliary tear-off line in the second direction, and the projected portion completely falls on the auxiliary cutting portion of the auxiliary tear-off line segment. In the second case, there is one main tear-off line segment and two auxiliary tear-off line segments, including a first auxiliary tear-off line segment and a second auxiliary tear-off line segment. The main non-cutting portion of the main tear-off line segment is projected onto the auxiliary tear-off line segment in the second direction. The projected portion completely falls on the auxiliary cutting portion of the first auxiliary tear-off line segment, or the projected portion consists of the portion falling on the auxiliary cutting portion of the first auxiliary tear-off line segment and the portion falling on the auxiliary cutting portion of the second auxiliary tear-off line segment. The above is an example for illustration. The situation when there are more than 2 auxiliary tear-off segments can be deduced by analogy based on the previous logic.

[0038] Implementation Case 1

[0039] Figures 1-3 This is a schematic diagram of packaging body 1 in this implementation case. Figure 1 This is a 3D view of packaging body 1. Figure 2 This is a diagram showing the unfolded packaging sheet of packaging body 1. Figure 3 This is a magnified close-up view of the tear-off section of the packaging body 1.

[0040] In this embodiment, the packaging body 1 is formed by folding and sealing a packaging sheet 1'. The packaging sheet 1' has a carrying opening at one end in the second direction Y. Near the carrying opening, there is a tear-resistant line segment 11 extending in the first direction X (the tear-resistant line segment 11 can also be located away from the carrying opening, not shown in the figure, but its specific form is easily conceived). The size of the tear-resistant line segment is equal to the size of the packaging sheet 1' in the second direction Y. The tear-resistant line segment 11 consists of two parallel first tear-resistant lines 111 and... The second tearable segment 112 is composed of a first tearable segment 111 as the main tearable segment and a second tearable segment 112 as the auxiliary tearable segment. Each tearable segment (the first tearable segment 111 and the second tearable segment 112) is composed of alternating cutting and non-cutting portions. The first tearable segment 111 includes a first cutting portion 111a and a first non-cutting portion 111b, and the second tearable segment 112 includes a second cutting portion 112a and a second non-cutting portion 112b. The first non-cutting portion of the first tearable segment 111... The cut portion 111b overlaps with the second cut portion 112a of the second tearable line segment 112 in the second direction Y. The width D2 of the first non-cut portion 111b is less than or equal to the width D3 of the second cut portion 112a. The first non-cut portion 111b is projected onto the second cut portion 112a along the second direction Y, and its projected portion is completely located within the second cut portion 112a. The second non-cut portion 112b of the second tearable line 112 overlaps with the first cut portion 111a of the first tearable line segment 111 in the second direction Y. The width D4 of the non-cutting portion 112b is less than or equal to the width D1 of the first cutting portion 111a. The second non-cutting portion 112b is projected onto the first cutting portion 111a along the second direction Y, and its projected portion is completely located within the first cutting portion 111a. This structural design ensures that the cutting line will inevitably pass through the crease. When the user tears open the packaging, no matter which area of ​​the easy-tear line the user applies force to, there will always be an easy-tear line segment to provide a cutting line, thus applying force to the cutting line and improving the ease of tearing open the packaging.

[0041] To further optimize the easy-tear line 11, this embodiment limits the size of the easy-tear line segment to ensure that it is easier to tear without effort, while also preventing insects from entering the packaging body 1 through the cut line. The width D1 of the first cut portion 111a is 0.5mm to 2mm, preferably 1mm to 1.5mm; the width D3 of the second cut portion 112b is 0.5mm to 2mm, preferably 1mm to 1.5mm; and the distance D5 between the first easy-tear line segment 111 and the second easy-tear line segment 112 is 0.5mm to 2mm, preferably 1mm.

[0042] The packaging body 1 has sealing portions at both ends in the second direction Y. The packaging sheets 1' of the sealing portions are bonded together, and the easy-tear line 11 does not overlap with the sealing portion to ensure that the easy-tear line 11 can function properly to open the packaging body 1.

[0043] Implementation Cases 2-3

[0044] Figures 4-5 The diagram shows a partial enlarged view of the tear line of packaging 1 in Implementation Case 2. Implementation Cases 2 and 3 further improve the design of the tear line. Similarly, the first tear line segment 111 is designated as the main tear line segment, and the second tear line segment 112 is designated as the auxiliary tear line segment. The cutting part of the first tear line segment 111 is set as a non-linear shape. The first cutting part 111a in Implementation Case 2 is set as an arc shape, and the first cutting part 111a in Implementation Case 3 is set as a "∧" shape. Both of these configurations have the function of guiding the tear line towards the second tear line segment 112 when tearing the tear line, preventing the tear line from deviating to the non-ideal outer side and improving the tearing effect.

[0045] Further size restrictions are imposed on the improved easy-tear line to ensure that it is easier to tear without effort, while also preventing insects from entering the packaging body 1 through the cut line. The width D1 of the first cut section 111a is 1mm-2mm, preferably 1.5mm; the width D3 of the second cut section 112b is 0.5-1.5mm, preferably 1mm; the distance D6 between the first easy-tear line segment 111 and the second easy-tear line segment 112 is 1mm-2.5mm, preferably 1.5mm; the distance D6 is the distance between the farthest point of the first cut section 111a from the second easy-tear line segment 112 and the second easy-tear line segment 112.

[0046] Implementation Cases 4-7

[0047] Figures 6-8The diagram shows a partial enlarged view of the tear line of the packaging body 1 in Examples 4-7. Examples 4-7 are further improvements on the above examples, increasing the number of auxiliary tear line segments from one to two. The auxiliary tear line segments include a second tear line segment 1121 (112) and a third tear line break 1122 (112). In Examples 4-6, the third tear line break 112b is preferably symmetrical about the second tear line break 112a and the first tear line break 111, which makes the entire tear line 11 symmetrical and improves its overall aesthetics. In Example 7, the third cutting line 1122a, the second cutting line 1121a, and the first cutting line 111a have a portion that is staggered in the second direction Y, but not completely staggered. As can be seen from the figure, the first non-cut portion 111b of the first tear line break 111 is in the second direction Y. The upper part overlaps with both the second cutting line 1121a and the third cutting line 1122a, so that the second cutting line 1121a and the third cutting line 1122a overlap completely with the first non-cutting part 111b. The second cutting line 1121a and the third cutting line 1122a are located on both sides of the first non-cutting part 111b, so as to reduce the possibility that the easy-tear section area has no cutting part in the longitudinal direction due to production errors during the production process, and ensure that the cutting line will definitely pass through the crease, thus ensuring the probability of improving the easy-tear effect.

[0048] In embodiments 5 and 6, the width D1 of the first cutting portion 111a is 1mm to 2mm, preferably 1.5mm; the width D3 of the second cutting portion 1121a is 0.5mm to 1.5mm, preferably 1mm; the distance D6 between the first easy-tear line segment 111 and the second easy-tear line segment 1121 is 1mm to 2.5mm, preferably 1.5mm; the distance D6 is the distance between the point on the first cutting portion 111a furthest from the second easy-tear line segment 1121 and the second easy-tear line segment 1121. The parameter settings for the third easy-tear line segment 1122 in embodiments 4 to 6 can refer to the parameters of the first easy-tear line segment 111. By limiting the parameters of the cutting lines, it is ensured that they are easier to tear without effort, while also preventing insects from entering the packaging body 1 through the cutting lines. In Implementation Case 7, D1 is 1.5mm, D2 is 1.5mm, L1 is 1.05mm, L2 is 0.45mm, L3 is 1.2mm, and L4 is 0.3mm.

[0049] Figure 9 The implementation state diagram of Case 4 shows that Case 4 has a cutting part in the folded part, forming a tearing notch, and the force applied here can easily tear the non-cutting part apart. Figure 11 The existing technology has a situation where the folded part overlaps with the non-cut part, and the packaging does not form a gap at the folded part, making it difficult and laborious for users to tear it open.

[0050] The above are only a few specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
