Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, specifically a breast milk packaging bag. Background Technology

[0002] Breast milk is the most natural, safest, and most complete natural food for infant growth. It contains all the nutrients and antibodies needed for infant growth. In particular, breast milk contains 50% fat, which not only provides the baby with energy but also meets the fat needs for the baby's brain development. The rich calcium and phosphorus can help the baby grow tall and strong. Immunoglobulins can effectively prevent and protect the baby from infection and chronic diseases. In addition, the close contact and parent-child relationship during breastfeeding can stimulate the baby's brain and mental development.

[0003] However, breast milk generally needs to be stored for convenient use when it is inconvenient later. Existing breast milk bags generally have the following drawbacks:

[0004] 1. The temperature of the breast milk inside the bag cannot be sensed; excessively high temperatures can lead to nutrient loss.

[0005] 2. Reserve observation relies on external comparisons, and the measurement is not intuitive;

[0006] 3. Bacteria can easily grow at the opening of the breast milk storage bag, which can easily cause breast milk infection when used later;

[0007] 4. The structure is simple, and the protection effect is poor during storage.

[0008] Therefore, we proposed a breast milk packaging bag. Utility Model Content

[0009] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0010] Therefore, the technical solution adopted by this utility model is as follows:

[0011] A breast milk packaging bag includes a bag body and an opening at the top of the bag body. The bag body is formed by heat-sealing a first sheet and a second sheet together. Both the first sheet and the second sheet are composed of a PET film, a nylon film, and a PE film laminated sequentially from the outside to the inside. A temperature-sensitive ink layer is printed on the inner surface of the PET film. A measuring scale is provided on the inner surface of the bag body. A reusable sealing strip is provided at the end of the opening.

[0012] In a preferred embodiment, the present invention can be further configured such that the temperature-sensitive ink layer is distributed in the lower half of the bag body, and its color development temperature is above 37°C.

[0013] In a preferred embodiment, the present invention can be further configured such that the measuring scale is printed on the inner surface of the PE film along the height direction of the bag.

[0014] In a preferred embodiment, the present invention can be further configured such that the sealing strip is a food-grade silicone strip symmetrically arranged on both sides of the opening.

[0015] In a preferred embodiment, the present invention can be further configured such that: the sealing strip is embedded with nano-silver particles to form an antibacterial layer.

[0016] In a preferred embodiment, the present invention can be further configured such that the measuring scale is printed with fluorescent ink.

[0017] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0018] 1. This utility model provides triple safety protection: the PET film provides mechanical strength, the nylon film blocks oxygen, and the PE film ensures food safety. The multi-layer composite design solves the problem of poor protection during storage.

[0019] 2. This utility model uses a temperature-sensitive ink layer to allow for direct observation of whether the temperature of breast milk is abnormal when it changes color due to temperature, thereby avoiding nutrient damage.

[0020] 3. This utility model allows for real-time monitoring of the amount of breast milk stored in the bag via a measuring scale, thus facilitating accurate measurement with one hand.

[0021] 4. This utility model, through the sealing strip, can provide both sealing and antibacterial effects, thereby preventing bacteria from accumulating at the bag opening and causing contamination. Furthermore, the sealing strip design allows the packaging bag to be reused, making it highly practical. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0027] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0028] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a breast milk packaging bag.

[0029] Combination Figure 1-2 As shown, the present invention provides a breast milk packaging bag, including a bag body 1 and an opening 2 at the top of the bag body. The bag body 1 is formed by a first sheet 11 and a second sheet 12 bound together by a heat-sealed edge 3. The first sheet 11 and the second sheet 12 are both composed of a PET film 111, a nylon film 112 and a PE film 113 sequentially laminated from the outside to the inside. The nylon film 112 provides high oxygen barrier properties, with an oxygen permeability of <5cm³. 3 / m 2 • PE film 113 ensures heat seal strength for 24 hours, with a heat seal strength ≥ 45N / 15mm.

[0030] Specifically, the inner surface of the PET film 111 is printed with a temperature-sensitive ink layer 4, and the temperature-sensitive ink layer 4 is distributed in the lower half of the bag body 1. Its color development temperature is above 37°C. The PET film 111 of the inner layer of the first sheet 11 is in direct contact with breast milk and is printed with a temperature-sensitive ink layer 4. When the temperature of the breast milk is >37°C, the ink changes from transparent to red as a warning.

[0031] Furthermore, the inner surface of the bag body 1 is provided with a measuring scale 5, which is printed on the inner surface of the PE film 113 along the height direction of the bag body. The amount of breast milk stored in the bag can be viewed in real time through the measuring scale 5, thus facilitating accurate measurement by one hand.

[0032] Furthermore, the end of the opening 2 is provided with a reusable sealing strip 6. The sealing strip 6 can play a good antibacterial role while playing a sealing role, thereby avoiding the accumulation of bacteria at the bag opening and causing contamination. The sealing strip is designed to be reusable for the packaging bag.

[0033] Furthermore, the sealing strip 6 is a food-grade silicone strip symmetrically arranged on both sides of the opening 2, which has a good sealing effect. At the same time, the sealing strip 6 is embedded with nano-silver particles to form an antibacterial layer, which can play a good antibacterial role.

[0034] Furthermore, the measuring scale 5 is printed with fluorescent ink, which allows the amount of breast milk to be viewed even in poor lighting conditions, making it convenient to use.

[0035] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
