Description

Edible lightweight straws {LIGHTNESS EDIBLE STRAW}

The present invention relates to a tubular molded article, in particular to a light and edible straw (Lightness Edible Straw).

The most common tubular molded article is a straw. The straw is generally divided into a straight tube, a stretch tube, and a flexible tube, and takes a hand beverage or liquid inside a packaging container.

After use, the straw is often thrown away in the trash. Since straw is generally a synthetic resin such as polypropylene (polypropylene, abbreviated PP), it is processed into a tubular molded article by a method such as injection molding, extrusion molding, blow molding or wire drawing. Since these synthetic resin products are not easily decomposed, the degree to which the straw destroys the surrounding environment is quite serious, affecting the global ecosystem. Under the expectations of many people, the use of straws made with biodegradable resins continues to evolve.

For example, Japanese Patent No. 5393566 discloses a straw that maintains excellent rigidity through processing procedures such as mold, heating, and diameter expansion, and at the same time, has obtained patent rights of Chinese Patent No. 102206402. The straw comprises an aliphatic polyester or an aliphatic-aromatic copolyester (Copolyester) occupying a specific gravity of 50% to 75% of the biodegradable resin; An aliphatic polyester or an aliphatic-aromatic copolyester having a relatively low flexural modulus and also occupying a specific gravity of 15% to 45%; It is divided into 3 components, inorganic fillers, which account for 5% to 25% specific gravity.

In addition, the straw of Taiwan Patent No. M469004 is made of an edible tubular molded product by wrapping the inner and outer surfaces of the hollow starch body using a double adhesive layer. The starch body is prepared by mixing a plurality of addition units in starch, and each addition unit can be sugar, salt, powdered milk or a combination thereof to change the taste of the starch body.

However, the solid tube wall is dry and hard and increases the overall weight of the straw, which is disadvantageous for chewing.

The inventor of the present invention aims to provide a new straw having a dual effect such as a light and crunchy texture by using an edible structure.

 In order to achieve the above object, the straw of the present invention forms one or more bodies by mixing starch and microcapsules in a certain ratio. The main body maintains a hollow structure through one of methods such as dehydration or drying, and the structure is introduced into the candle farm as a tube wall, thereby generating the infiltration effect on the body.

 Here, such microcapsules include at least one set of hollow capsules and one set of solid capsules, and each microcapsule is a micro-type capsule having a diameter of between 30 μm (micrometers) and 1000 μm. The hollow capsule is surrounded by a wall material to form a certain volume of the inner chamber, but the inner chamber receives a constant volume of gas to complete a straw having characteristics such as light and edible in a solid state to generate a crunchy texture. The solid capsule is surrounded by a wall material to form a solid or liquid core material, thereby changing the chewy taste of the straw.

Hereinafter, one or more comparatively preferred embodiments will be described in detail with reference to the accompanying drawings so that the above objects, structures, features and advantages of the present invention are more clear.

2 and 3 are cross-sectional views of different uses of the microcapsules.
4 is a cross-sectional view of the first embodiment of the straw.
5 is a cross-sectional view of a second embodiment of a straw.

In FIG. 1, the straw 32 undergoes steps such as mixing 10, infiltration 20, and finished product 30.

The body 16 is manufactured from a mixed liquid (for example, clean water) of the starch 12 and the microcapsules 14 according to a constant (eg, weight) ratio. The main body 16 maintains the hollow structure through one of methods such as dehydration or drying (eg, heating, drip drying), and is introduced into the candle 22. The candle 22 generates an infiltrating effect on the main body 16 to complete a tubular molded product having characteristics such as light weight and edible in a solid state.

In the edible aspect, the starch (Amych or Amylum) 12 refers to powder or particles formed by grinding plants, for example wheat, potato, corn, sweet potato, cassava, lotus root, rice and konjac or modified starch. The candle 22 is an edible wax attached to the surface of the body 16, for example, a natural product of animals or plants, or formed by combining fatty acids with natural wax (for example, combining fatty acids with beeswax or beeswax). Therefore, the entire straw 32 has edible properties.

When observing the internal structure of the straw 32 from FIGS. 2 to 4, the main body 16 has an inner 161, an outer 162, a first cross section 163, and a second cross section 164 around the tube wall. It is an edible tube of constant thickness that is divided. The protective film 34 of one layer surrounds the inner 161, outer 162, first cross-section 163, and second cross-section 164 of the body 16, and the inner film portion 341, outer film portion 342, The upper part 343 and the lower part 344 are formed. Therefore, since the protective film 34 isolates the main body 16 so as not to come into contact with a liquid (for example, water), the weights of the main body 16 and the protective film 34 are generally equal to the total weight of the straws 32.

In other words, the starch 12 or the microcapsule 14 becomes one of the control elements of the straw 32, so that the total weight can be determined through a separate weight ratio.

In this embodiment, the tube wall of the straw 32 is hollow and is sufficient for the straw 32 to have light properties. Briefly, when the microcapsules 14 are hollow, the straw 32 includes a tube wall forming a hollow in the hollow microcapsules 14. When the microcapsules 14 are solid, the straw 32 includes a tube wall forming a solid in the solid microcapsules 14.

Under the conditions of the same standard and size, the hollow straw 32 mass (or weight) of the present embodiment is naturally lighter than the solid edible straw. And, when an arbitrary user chews the hollow straw 32, a crunchy texture may occur.

In the figure, the microcapsules 14 are micro-type capsules having a diameter of between 30 μm (micrometer) and 1000 μm. The manufacturing method of the microcapsule is, for example, spray condensation method, electrostatic bonding method, porous eccentric method, water / oil separation method, double emulsion method, powder bed method, interfacial polymerization method, in situ polymerization method and radiation packaging method, etc. There are quite a lot. The microcapsule 14 has a wall material 142 such as a thin film surrounding a core material 145 in a gas, liquid, or solid state. The wall material 142 maintains a fixed volume so that the microcapsules 14 have a certain strength.

According to the physical state of the core material 145, the micro-type capsule is divided into a plurality of sets, at least one set being a hollow capsule 141 and the remaining micro-type capsules are solid capsules 144. The hollow capsule 141 is surrounded by a wall material 142 to form a certain volume of the inner chamber 143, wherein the inner chamber 143 accommodates a gas such as air having a constant volume. As described above, the position of the hollow capsule 141 in the straw 32 corresponds to the hollow tube wall, and the larger the quantity of the hollow capsules 141, the lighter the mass of the straw 32 is.

Here, the solid capsule 144 is generally a wall material 142, a solid or liquid core material 145, for example, cream, chocolate sauce, strawberry jam, and other flavored dairy products (fruit milk powder, ginger juice powder, cola powder milk) , It includes foamed milk powder, etc.), sweeteners (for example, aspartame) and seasonings (for example, lemon oil, mint oil, garlic oil, curry oil, etc.). As described above, the solid capsule 144 is provided so that the straw 32 has a blending effect of multiple textures giving different tastes such as sour, sweet, bitter, and spicy.

Of course, the shape of the body 16 is various. In some embodiments, the body 16 may be a spherical or elliptical tubular body, as well as transform the shape of the inner 161, outer 162, first cross section 163 and second cross section 164 , Relatively change the shape of the inner film portion 341, the outer film portion 342, the repayment portion 343, and the lower portion 344 of the protective film 34. Or, by changing the second end surface 164 of the main body 16 from a flat circular surface to an inclined circular surface shown in FIG. 5, the straw 32 is provided with an inclined lower part 344, which allows the present invention. Belongs to the scope.
