By the reference respective drawings the preferred embodiments of the present invention are described.
Fig. 1 is the front view according to a fruit of the present invention and growing vegetables bag; Fig. 2 is the rearview according to a fruit of the present invention and growing vegetables bag; Fig. 3 is accompanying drawing and the enlarged drawing according to a fruit of the present invention and growing vegetables bag; Fig. 4 is the upward view according to a fruit of the present invention and growing vegetables bag; Fig. 5 is by using the stereogram of the pumpkin of planting out according to a fruit of the present invention and growing vegetables bag.
With one deck LLD (linea low density) mixed film is superimposed and constitute by the synthetic thin film of hot melt, the while can obtain to have the bag of the transparency of enhanced strength and expectation to the bag that is used to plant fruit or vegetables according to the present invention by one deck PET film.Synthetic resin striped member be placed into the adhesive segment of described bag and by hot melt so that itself and described adhesive segment hot melt be integral to strengthen the cohesive force of described adhesive segment.The inlet part on the top of described bag is used to insert the cucumber or the pumpkin that do not grow up to the linear opening.The lower seal of described bag forms arc and is used for matching with the bottom shape of cucumber or pumpkin, and cucumber or pumpkin can be with unified size growths like this.Growing environment according to cucumber or pumpkin, the ventilation hole of proper number and osculum are formed at the upper and lower of described bag, thus, big cucumber in bottom or pumpkin have been prevented to grow, and, at least one osculum is formed on the hermetic unit of described bag bottom, and the water that accumulates in like this in the bag can flow to the outside.
Cucumber or pumpkin length are understood chap behind certain-length.Constant all the time for the length that guarantees cucumber or pumpkin, determine the length of fruit and growing vegetables bag 1 according to the full-length of cucumber or pumpkin, prevent that thus cucumber or pumpkin are long again.More preferably, the bottom of described bag 1 is made into arc shape and is used for matching with the bottom shape of cucumber or pumpkin.Being about to described bag 1 after cucumber or pumpkin blossom fall is wrapped on the pumpkin that does not grow up to.When parcel cucumber that does not grow up to of marsupial 1 or pumpkin growth and when arriving the hermetic unit of bottom full-length of bag, longitudinal growth finishes, and cross growth simultaneously begins and fills up bag basically.At this moment,, can guide the no longer crooked growth of cucumber or pumpkin, avoid crooked cucumber or pumpkin basically by using this bag.
Along with cucumber or pumpkin growth, growth pressure can tear the bag of being made by the synthetic resin material usually, and this synthetic material is difficult to bear this pressure, and like this, cucumber or pumpkin will be exposed to agricultural chemicals, and the product quality of cucumber or pumpkin will descend.Therefore, the bag 1 that is used for cucumber or pumpkin planting should not be elongated under the growth pressure of cucumber or pumpkin, and should provide the light transmission function.
In the present invention, have above-mentioned feature in order to make this bag, the experimental result of several synthetic resin shows that the PET film can satisfy above-mentioned condition by hot melt and the superimposed thin film that obtains of LLD mixed film.
PET is a kind of crystalline plastic material of making by terephthalic acid (TPA) and ethylene glycol polycondensation, and this material is transparent and have warm tolerance, intensity, electrical characteristics and grease proofness, and these characteristics can be advantageously applied to the material of cucumber and pumpkin planting bag.Therefore, the present invention has adopted this PET film as one of material of bag.
In the present invention, the PET film uses with the amount of 20～45 weight %.
LLD is meant linea low density, is also referred to as the 3rd PE, is mainly used in preservative film or food package film.
LLD has the high grade of transparency, and intensity increases when heat bonding, therefore can not elongate when applying external pressure, and thus, LLD is the suitable material that is used for cucumber or pumpkin planting usefulness bag.
In the present invention, antifoggant and anti-electric charge agent are mixed with LLD be used for making film.Here, this antifoggant is used for preventing the fog of wrapping paper inside, can make product seem brand-new and fresh.Should anti-electric charge agent be used to remove static.
In the present invention, with respect to the LLD of 60～98 weight %, add the antifoggant of 1～25 weight % and the anti-electric charge agent of 1～15 weight % and make the LLD mixed film, this film is as the material of described bag.
When the addition of antifoggant is lower than 1 weight %, because anti-fog performance is low, can atomize, when addition surpasses 25 weight %, anti-fog performance is fairly good, but printing performance and heat bonding performance are bad, and manufacturing cost increases, and heat bondable temperature can rise, and these have caused not good performance.
The LLD mixed film is the anti-electric charge agent mixing by the antifoggant of the granular LLD material of 60～98 weight %, 1～25 weight % and 1～15 weight %, and heats the gel state mixture of making in 3～5 minutes under 150～220 ℃ temperature.This gel state mixture is blown to the appearance of balloon and makes flat LLD mixed film.
In the present invention, the LLD mixed film uses with the amount of 55～80 weight %.
Manufacture method according to bag film of the present invention is described below.
Preparation thickness is the PET film of 0.01～0.09mm, and, use the PET film of 20～45 weight % and the LLD mixed film of 55～80 weight % in the present invention, but mixture not to be mixed by PET film and LLD mixed film.That is, above-mentioned two film stack are combined into a slice film.Because the width of two films is all identical, so determine the weight % of two films according to the thickness of every film.Because the thickness of bag is 0.06～0.2mm, so be that the PET film of 0.01～0.09mm and LLD mixed film that thickness is 0.05～0.11mm are superimposed to make thin film with thickness.
Therefore, making thickness is the LLD mixed film of 0.05～0.11mm, and, flat LLD mixed film is the anti-electric charge agent mixing by the antifoggant of the granular LLD of 60～98 weight %, 1～25 weight % and 1～15 weight %, and under 150～220 ℃ temperature, heat and made in 3～5 minutes, thereby make a kind of gel state mixture.The gel state mixture that makes like this is blown to the appearance of balloon.
When the PET film with same widths and LLD mixed film superimposed, and when heating down for 70～100 ℃, this PET film and this LLD mixed film are melted bonding, make the film that thickness is 0.06～0.2mm thus, the film that makes like this is transparent, and enough intensity is arranged to bear the growth pressure of cucumber or pumpkin, therefore this bag can not elongate.
It is wide that described bag film is cut into 8～20cm, and 20～33cm is long, and this bag film to be folded into 4～9cm wide, 20～33cm is long.Bag 1 top with the linear opening in order to form import 30, cucumber or pumpkin that this import 30 is used for not growing up to insert wherein, the bottom of this bag 1 is sealed to arc, is used to form hermetic unit 50, and synthetic resin striped member 31 is formed between the edge 30a and 30b of adhesive segment 30, in this adhesive segment 30, the two ends of bag film join and are folding, and this folded part is made one thus and has 0.06～0.2mm thickness by hot melt, 4～9cm width, the bag of 20～33cm length.When described adhesive segment 30 at 70～100 ℃ down rapidly during heating, the striped member of adhesive segment 30 and synthetic resin 31 is bondd by melt-through.
The striped member 31 of synthetic resin is to be mixed by the polyamide of the EVA (ethylene vinyl acetate) of 60～80 weight % and 20～40 weight % to heat 3～5 minutes under the temperature that is incorporated in 150～220 ℃ and make, make a kind of gel state mixture thus, this gel state mixture is made into flat pattern and is used to make film.Described EVA is level and smooth and has high tension.
The striped member of synthetic resin is owing to following reason is integrally inserted adhesive segment 30.That is, after cucumber or pumpkin grew into their length fully, they stopped growing, and their chaps are inner to fill up bag fully then.Because cucumber or pumpkin chap, the pressure that imposes on bag is very big.Therefore, in fruit and vegetables bag 1, weakest part is exactly an adhesive segment 30.A lot of methods have been attempted in order to strengthen this adhesive segment.According to Korea S's publication number is the patent of 10-2007-0047666, rectangular bag film is so that the edge 34a of its width and 34b and the contacted mode of inner surface are folding, and with the folded part hot adhesion, so tensile stress is applied on the surface of melt-through bonding.Therefore, this bag is owing to the growth pressure of cucumber or pumpkin is torn.In order to improve the problems referred to above, applicant's invention of above-mentioned patent has also been applied for the 20-0406155 Korean Utility Model, but the invention of this routine also has above-described problem.
In the present invention, in order to strengthen the cohesive force of adhesive segment 30, in the hot melt and the adhesive segment 30 that bonds, a synthetic resin striped member 31 is put between the edge 30a and 30b of adhesive segment 30.Heating adhesive segment 30 under the state that synthetic resin striped member 31 is placed into is along with the film of this adhesive segment 30 and the striped member of this synthetic resin material 31 are combined into one by hot melt and with adhesive segment 30.Therefore, the cohesive force of adhesive segment 30 is enhanced by this synthetic resin striped member 31, can bear the growth pressure of cucumber or pumpkin thus basically.Therefore, even cucumber in the bag 1 or pumpkin growth also can avoid adhesive segment 30 to be torn.In order to prevent to grow big cucumber in bottom or pumpkin, the top 11 that a plurality of ventilation holes 40 are horizontally formed at described bag respectively (promptly, with import 20 distances 4.7～5.3cm place of described bag) and 12 places, middle and upper part of described bag (that is, with the import 20 of described bag apart from 8.5～9.5cm place).
