Description

DISPOSABLE BAG FOR FEEDING INFANTS

The technical field to which the invention relates.

The invention relates to horns (bottles) for feeding, and more particularly to disposable bags for feeding baby food, including a container of flexible soft material that forms a chamber for accommodating baby food, and having an opening at one end, hermetically connected to a rigid means, adapted for connection with a protective cover or nipple, and can be used for feeding infants.

The level of technology.

There are many bottles for feeding babies. Among them there are solutions in which a disposable container made of flexible soft material is used as a bottle. This is very important to ensure sterility, especially necessary for the baby in the first months of his life.

For example, a disposable pouch for feeding infants is known from the prior art, including a container of flexible soft material forming a chamber for containing baby food and having an opening at one end hermetically connected to a rigid means adapted for connection with a protective cover or nipple, see Description of the application for the invention Ns2005135458, published March 10, 2006

This device is the closest in technical essence to the claimed invention and is taken as a prototype to the proposed invention.

The disadvantage of this device is the low ease of use when feeding infants, which is due to the fact that when feeding you need to monitor the temperature of baby food - the contents of such a device, and it is difficult to measure the temperature of baby food when it is inside such a device. It is necessary, for example, to break the tightness and lower the thermometer inward, to wait for the result. At the same time, baby food could be at a normal temperature and was ready to feed the baby, and as a result of such manipulations it can cool down and it will need to be warmed up. Disclosure of the invention.

Based on this original observation, the present invention mainly aims to offer a disposable bag for feeding infants, allowing to smooth at least one of the above disadvantages.

Achievable technical result - increased ease of use when feeding infants due to the possibility of indicating the temperature of the mixture and the ability to indicate when it is necessary to heat or cool baby food.

To achieve this, a container of flexible soft material has a means for indicating the temperature of the contents.

Thanks to this advantageous characteristic, it becomes possible to indicate to the user who is feeding the baby the temperature of the contents of the disposable bag. At the same time, it becomes clear whether it is possible to feed the baby right away, or whether it is necessary to heat / cool baby food.

There is an embodiment of the invention in which a means for indicating the temperature of the contents is located on the outer surface of the container of flexible soft material.

Thanks to this advantageous characteristic, it becomes possible to easily produce such disposable bags by placing any type of temperature indicator on the surface of the container.

There is an embodiment of the invention in which the means for indicating the temperature of the contents is in the form of a film thermal indicator.

Thanks to this advantageous characteristic, it becomes possible to use a standard film thermal indicator.

There is a variant of the invention in which the film thermal indicator is made in the form of three parallel strips equally spaced from each other and located along the container of flexible soft material along the entire length of the container.

Thanks to this advantageous characteristic, it becomes possible at a glance to control the temperature of baby food on either side of the container and in any part of the container, which is especially important since the container is made of flexible soft material and can take various forms, and baby food can be in isolated from each other places of the container. There is an embodiment of the invention in which the thermal indicator further includes two layers of a hermetically laminated film between which are placed film markers that respond to a change in temperature of the contents by a color change.

Thanks to such an advantageous characteristic, it becomes possible to easily produce such film thermal indicators based on an existing technology using film markers that respond to changes in temperature of the contents by a color change.

There is a variant of the invention in which the film thermal indicator additionally consists of a layer of a substance that changes color under the influence of temperature.

Thanks to this advantageous characteristic, an alternative embodiment of the invention is possible, using, for example, thermochromic paints that change color under the influence of temperature with the possibility of restoring the original color, i.e. using reversible fading temperature-sensitive ink.

There is an embodiment of the invention in which the temperature indication means is made in the form of a fiber uniformly located in the walls of the container and which responds to a change in temperature of the contents by a color change.

Thanks to such an advantageous characteristic, it becomes possible to manufacture the container itself with the participation of a substance that reacts to a change in the temperature of the contents by a color change.

There is an embodiment of the invention in which the temperature indicating means is made in the form of a component that responds to a change in temperature of the contents by changing the color added to the material of which the container is made of flexible soft material.

Thanks to this advantageous characteristic, it becomes possible to produce an alternative embodiment of the container itself with the participation of a substance that reacts to a change in the temperature of the contents by a color change.

There is a variant of the invention in which the means for indicating the temperature of the contents is made in the form of three parallel strips of film thermometers equidistant from each other and located along the container of flexible soft material along the entire length of the container. Thanks to this advantageous characteristic, it is possible to control the temperature very precisely. The sensitivity of the film thermometer is much higher than many other thermal indicators. They can be used to measure temperature changes that make up only 0.1 ° C. It becomes possible to measure a short-term temperature with a response time of only a few microseconds.

There is a variant of the invention in which the means for indicating the temperature of the contents made in the form of three parallel strips equally spaced from each other and located along the container of flexible soft material along the entire length of the container can be adapted to change its color under the influence of temperature, while it can be at least in three possible color states, one of which corresponds to a reduced temperature of baby food for feeding the baby, the second of which corresponds to normal temperature of baby food for feeding the baby, the third of which corresponds to an elevated temperature of baby food for feeding the baby.

Thanks to this advantageous characteristic, it becomes possible to quickly transmit the necessary information to users of the invention regarding readiness for feeding the baby. It is enough to see that the temperature indicator means, for example, in green. Two other options for its color instantly give you the idea that you need to heat or cool baby food.

The set of essential features of the invention is unknown from the prior art for devices of similar purpose, which allows us to conclude that the criterion of "novelty" for the invention.

A brief description of the drawings.

Other distinguishing features and advantages of the invention clearly follow from the description below for illustration and not being restrictive, with reference to the accompanying drawings, in which:

- figure 1 schematically depicts a functional diagram of a disposable bag for feeding infants complete with a protective cover, side view, according to the invention. - figure 2 schematically depicts a top view of a disposable bag for feeding infants in the embodiment of the thermal indicator in the form of three parallel strips equidistant from each other, according to the invention.

- figure 3 schematically depicts a functional diagram of a disposable bag for feeding infants complete with a pacifier and a protective cap, side view, according to the invention.

- figure 4 depicts the steps of using a disposable pouch for feeding infants, according to the invention.

According to figures 1 and 3, the disposable bag for feeding infants includes a container 1 of flexible soft material forming a chamber for containing baby food, and having an opening 2 at one end, hermetically connected to a rigid means 3 adapted for connection with a protective cover 4 or with a lid with a hole 8 for fastening the nipple 5 with the nipple 5.

A use case of the invention with a protective cover 4 is shown in figure 1, and a use case of the invention with a pacifier 5 is shown in figure 3.

Capacity 1 made of flexible soft material has a means of indicating temperature 6. Figure 1 shows a variant with one means of indicating temperature, figure 2 shows a variant when such means 3 and they are equidistant from each other. In general, there may be more than three.

At the same time, both the nipple 5 and the protective cover 4 on the rigid means 3 of the bag cannot be fixed. A protective cover 4 is needed to seal the bag before its first use and the subsequent use of this cover according to the logic of the implementation of the model is not assumed. The protective cover 4 for sealing does not have and does not imply any means for attaching the nipples to it.

The outer surface of the protective cover 4 is non-sterile. Therefore, the contact of the nipples with it is unhygienic. The protective cover 4 does not have devices for attaching the nipples 5 or the protective cap 7 to it.

The temperature indicating means 6, made in the form of three parallel strips equidistant from each other, can be located on the outer surface of the container 1 from a flexible soft material. Means for indicating temperature 6 can be made in the form of a film thermal indicator. The film thermal indicator can be made in the form of three parallel strips equally spaced from each other and located along the entire length of the container 1 from a flexible soft material. See figure 2.

The film thermal indicator in the form of three parallel strips equally spaced from each other and located along the entire length of the container 1 from flexible soft material can be made three-layer and include two layers of a hermetically laminated film between which are placed film markers that respond to changes in the temperature of the contents by changing colors.

The means for indicating the temperature of the contents 6 can be made in the form of a layer of a substance deposited by three parallel strips equidistant from each other and located along the entire length of the container 1 from a flexible soft material that changes color under the influence of temperature.

The means for indicating the temperature of the contents 6 can be made in the form of a fiber uniformly located in the walls of the container along the entire length of the container 1 and which responds to a change in temperature of the contents by a color change.

The means for indicating the temperature of the contents 6 can be made in the form of a component that responds to changes in the temperature of the contents by changing the color added to the material from which the container is made of flexible soft material.

The means for indicating the temperature of the contents 6 can be made in the form of three parallel strips of film thermometers equidistant from each other and located along the container of flexible soft material along the entire length of the tank 1.

The means for indicating the temperature 6 of the contents can be adapted to change its color under the influence of temperature, while it has the ability to be in at least three possible color states, one of which corresponds to a reduced temperature of baby food for feeding the baby, the second of which corresponds to the normal temperature of baby food for feeding the baby, the third of which corresponds to an elevated temperature of baby food for feeding the baby. Additionally, figure 3 denotes elements that are not included in the object of the invention, but can be used with it. This is the protective cover 4 of the container, the nipple 5, the protective cap for the nipple 7. The protective cap for the nipple 7 has an annular protrusion under the dome of the protective cap at the point of contact with the nipple. The annular protrusion is in close contact with the nipple 5 and prevents the involuntary leakage of baby food through the nipple 5.

The nipple 5 can be attached to the rigid means 3 of the disposable bag using a special cover 8 with an opening for attaching the nipple 5, made as a separate fastener.

A disposable bag for feeding infants can have a capacity of 1 different volumes, for example, 50, 150, 200 ml, which can be made of a transparent material that does not allow water to pass through, for example, food grade polyethylene.

The neck of the container 1, formed by the hole 2, is hermetically connected to a rigid means 3, which is a short, moisture-resistant transparent pipe made of food material, for which you can hold a disposable bag when preparing baby food, for example, milk mixture and when feeding. On the outer surface of the rigid means 3, from the side of the opposite container 1, there may be a thread for attaching either the protective cover 4 of the container 1 or the cover 8 with an opening for securing the nipple 5. The protective cap 7 is not screwed on, but is pushed onto a special cover 8 with an opening for fastenings of the nipples 5. On the outside of the cover 8 there is a groove along the entire length of its circumference, and on the inside of the edge of the protective cap 7 there is an annular protrusion along the entire length of its circumference. An annular protrusion on the inner side of the edge of the protective cap 7 fits snugly into the groove on the outer side of the lid 8 and reliably fixes the cap 7 on the lid 8. Not shown in the figures.

To ensure sterility of the disposable pouch before the first use, the rigid means 3 from the outside can be tightly closed by a protective cover 4 made, for example, of thin metal. But there may also be an option when the disposable bag initially additionally has sealed packaging. In this case, it can be used without a protective cover 4 and after opening the package is filled with baby food, connected to the cover 8 with a hole for attaching the nipple 5 with the pacifier 5 installed in the lid 8 and is immediately ready for use. Flexible plastic material of capacity 1 allows the nipple 5 to automatically automatically position itself in the baby’s mouth without interference, which positively affects the feeding process.

In the case of using a protective cover 4 to improve sealing, the surface of the cover in contact with the rigid means 3 may be coated with a sealant, such as food rubber. The figure 1 is not shown.

In the case of using the protective cover 4, it can be screwed onto the rigid means 3 in an environment of hot air and thus seal the disposable bag. Before screwing on the protective cover 4, the container 1 of the bag must be flattened beforehand to reduce the effect of the air volume in it on the air pressure inside the hard tool 3 after cooling the air in the neck of the hard tool 3 under the protective cover 4. Since the walls of the container 1 of the bag tightly close when cooling, the material of capacity 1 of the bag should not stick together when closed.

Rigid means 3 in the case of ensuring sterility of the disposable bag before the first use of the protective cover 4 is made in the form of a glass with a perforated bottom facing the side of the container 1. Thus, when cooling in the container 1, the air leaves it, but the flexible plastic material of the container 1 is rigid the tool 3 is not retracted, which ensures a guaranteed decrease in air pressure in the inside of the hard tool 3, sufficient to retract the cover 4 into the internal volume of the hard tool 3 until it clicks.

When cooling the air inside the rigid means 3, the volume of air becomes smaller, which leads to a decrease in pressure inside the rigid means 3 so that the protective cover 4 is concave inside the hard means 3. The protective cover 4 should be designed so that it bends inside the hard means 3, she gave a distinctive click. This property of the protective cover 4 is important for monitoring the tightness of a disposable bag. The protective cover 4 can be easily removed with one movement of the hand by turning it counterclockwise. When equalizing the pressure inside and outside the disposable bag at the time of removal of the protective cover 4, the protective cover 4 restores its shape with a distinct click. This click is a sign of the suitability of the disposable pouch for use.

To control the volume of the contents of a disposable bag, a scale in units of volume, for example, in milliliters, with convenient division price, for example, at 10 milliliters. The values on the scale can be located to the left and right of the scale. On one side of the scale in the direction of decreasing values, on the other side of the scale in the direction of increasing values. This arrangement of values allows you to immediately determine both the amount of food eaten and the amount of baby food left. At the same time, to find out the volume of contents of a disposable bag, you need to take it by a hard tool 3 with a hard tool 3 up. The line along which the walls of the tank 1 are joined together, will be on the division of the scale, which coincides with the volume of the contents of the bag. A scale for determining the volume of the contents of the bag can be applied to the outside of the bag from three sides and placed between the strips of the thermal indicator. The scale in the figures is not shown.

Advantageously, the container 1 is made of a transparent material, since transparency is important for controlling the complete dissolution of the dry mixture when preparing the milk mixture directly in the bag.

A disposable bag can have the following configuration options:

The first option: a disposable bag, sterile inside, closed with a protective cover 4, cover 8 with an opening for attaching the nipple 5 to the rigid tool 3, the nipple 5, a transparent protective cap 7 to protect against involuntary leakage of baby food through the nipple 5.

The second option: only a disposable bag, sterile inside, closed with a protective cover 4.

Third option: a disposable bag in a sealed package, sterile inside and out.

The container 1 and the rigid means 3 can be made, for example, cast, from the same material as a single unit. Sufficient rigidity of the rigid means 3 and flexibility and ductility can be achieved by selecting the thickness and properties of the material.

The implementation of the invention.

Disposable bag for feeding infants works as follows. A non-limiting embodiment of the invention is given by way of example of the first embodiment of a disposable bag.

According to figure 4: Stage A1. Prepare a disposable bag for feeding infants, closed with a protective cover 4, milk mixture, warm water to dissolve the mixture, a pacifier 5, a lid 8 with an opening for attaching the nipples 5 to a rigid means 3, and a protective cap 7 to protect against inadvertent leakage of baby food through the nipple 5 .

Stage A2. Insert the pacifier 5 into the opening of the lid 8 for fastening the nipple 5 to the rigid means 3 and, holding the lid 8, pull the nipple 5 by the tip so that the nipple 5 is evenly fixed in the lid 8 using a special rim on the nipple 5. Not shown in the figures. Tightly put on the cover 8 with a pacifier 5 fixed in it, a protective cap 7.

Stage A3. Open a jar of milk powder and prepare a measuring spoon.

Stage A4. Take a disposable bag by a hard tool 3 with one hand, and with the other hand remove the protective cover 4 from the hard tool 3. To do this, grasp the protective cover 4 tightly with the other hand and turn it counterclockwise with force. If the protective cover 4 clicked, the disposable bag was sealed and can be used. If the lid does not click, throw out this disposable bag, you can not use it.

Stage A5. Pour milk mixture into a disposable bag

Stage A6. Pour warm water into a disposable bag to the required volume, controlling the volume on a scale on a disposable bag.

Stage A7. The cap 8 is tightly screwed with the pacifier 5 fixed in it and the protective cap 7 put on it on the rigid means 3.

Stage A8. Taking a disposable bag with one hand on a hard tool 3 soother 5 up, dissolve the milk mixture, kneading for this one-time bag with the fingers of the other hand.

Stage A9. Holding the disposable bag with one hand by the rigid means 3 with the pacifier 5 up, remove the protective cap 7 from the lid 8 and remove air from the disposable bag, gently squeezing the disposable bag with the other hand. Air will escape through the vacated nipple opening 5 and will not cause colic in the baby.

Stage A10. The temperature of the baby food is controlled by means of a temperature indicator 6. If it is made in the form of means adapted to change its color under the influence of temperature, and has the ability to be in at least three possible color conditions, when indicated by a color that corresponds to a reduced temperature of baby food, baby food is heated until the temperature indicator 6 changes color to one that corresponds to the normal temperature of baby food in order to feed the baby. When indicated with a color that corresponds to the elevated temperature of the baby food, the baby food is cooled until the temperature indicating means 6 changes color to one that corresponds to the normal temperature of the baby food for feeding the baby. When indicated with a color that corresponds to the normal temperature of baby food, they proceed to the next step.

Stage A11. The baby is fed.

Stage A12. If the feeding is interrupted, and the baby food is left in a disposable bag, the protective cap 7 is pulled over the lid 8 with a pacifier 5 and the disposable bag is put aside.

Stage A13. At the end of feeding, unscrew the lid 8 with a pacifier 5 from the hard means 3 and discard the disposable bag.

The above options of the invention are exemplary and allow you to add new options or modify the described without losing the ability to display the temperature of the contents. For example, instead of cooling or heating baby food, it is enough to mix it, then the hot areas will mix with the cold, and the general temperature will become optimal for feeding.

Industrial applicability.

The proposed disposable bag for feeding infants can be carried out by a specialist in practice and, when implemented, ensures the implementation of the declared purpose. The possibility of being implemented by a specialist in practice follows from the fact that for each feature included in the claims on the basis of the description, the material equivalent is known, which allows us to conclude that the criterion of "industrial applicability" for the invention is met, as well as the criterion of "completeness" for the invention.

In accordance with the proposed invention, the applicants made a disposable pouch for feeding infants.

Food grade polyethylene was used as the material. As a means of indicating temperature, a film thermal indicator was used, which was made in the form of three parallel strips equally spaced from each other, attached along the entire length outside the container 1. The thermal indicator was chosen so that it had a certain color in the range of 36-40 ° C. With increasing temperature, he changed color to a second color. With decreasing temperature increase, he changed color to a third color. Its accuracy was 0.5 ° C.

The pilot operation of a disposable pouch for feeding infants showed that it allows you to:

- carry out sterile filling with baby food and feeding the baby;

- carry out constant monitoring of the temperature of baby food during the preparation of baby food and during feeding;

- register deviations from the required temperature in different parts of the tank 1 due to the fact that the temperature indicator 6 is made along the entire length of the tank 1.

Thus, due to the presence of a temperature indication means, it becomes possible to continuously display the temperature of the baby food. All this, ultimately, ensures the achievement of the technical result achieved - improving ease of use when feeding babies.

An advantage of the use of this invention is also that the process of feeding infants becomes very simple. In addition to sterility, anti-colic protection and the comfort of the baby's nipples in the mouth, provided with a disposable bag, the control over the necessary temperature of baby food is also simplified.

It is recommended that this invention be widely used in various institutions, at home.
