Disposable container {Disposable container}

The present invention relates to a disposable container, and more specifically, is manufactured using environmentally friendly materials such as sugar cane pulp and bamboo pulp, and in particular, it is easy to seal a vinyl film on the upper part of the container body, and sticky rice from the container body. It relates to a disposable container that makes it easy to fall off.

In general, disposable containers used for delivery by restaurants are mainly made of plastic or styrofoam.

Since such a disposable container is not recovered after use and discarded, it adversely affects environmental pollution, so the use of a disposable container made of the above material is legally regulated.

Accordingly, in recent years, a disposable container made of a paper material has been used.

Disposable containers made of paper are manufactured and used in a variety of shapes according to the food to be contained therein.

In particular, in order to maintain the freshness of the food contained inside the disposable container and to prevent the food from leaking to the outside, the inside of the container must be sealed. For this purpose, a lid made of a resin material is used.

An example of such technology is disclosed in Patent Document 1 and Non-Patent Document 1 below.

Non-Patent Document 1 discloses an eco-friendly disposable container made of inexpensive sugarcane raw materials, harmless to the human body and not emitting toxic substances.

However, the conventional technology as described above has a problem in that the sealing of the vinyl film around the top of the container is not well done, unlike the disposable container made of plastic material in which the sealing of the vinyl film (wrap) is easy.

Therefore, in the prior art, there is a problem in that a lid made of a resin material is separately prepared to cover the opening formed on the upper part of the container body, which increases the cost of purchasing the lid, and the soup or the like leaks during the delivery process. There is a problem of contamination of the surroundings, and in the case of incinerating a lid made of resin, there is a problem of generating a large amount of pollutants and causing environmental pollution.

In addition, in the prior art, when the sticky rice contained in the container body is released with a spoon or the like, the rice grains do not easily fall from the inner surface of the container body, and the inner surface of the container body is torn off in the process of dropping the rice grains.

Hereinafter, the most preferred embodiment of the present invention will be described in detail in order to explain in detail to the extent that those skilled in the art can easily implement the present invention.

As shown in Figures 1 to 8, the disposable container according to the present invention is manufactured using environmentally friendly materials, and in particular, it is easy to seal the vinyl film on the top of the container body 100, and the container body 100 is tenacious. It is to make the rice with the easy fall, and includes the container body 100 and the pattern part 200.

The container body 100 has a structure in which a receiving space is formed therein and an upper part is opened. The container body 100 may be formed in various sizes and shapes.

A packaging vinyl film 300 is attached to the upper circumferential surface of the container body 100 , and the vinyl film 300 may be heat-sealed and attached to the upper circumferential surface of the container body 100 .

A plurality of reinforcing protrusions 120 protrude from the inner surface and the bottom surface of the container body 100 . Due to the formation of the reinforcing protrusion 120, it is possible to prevent bending or torsional deformation of the container according to food load.

Meanwhile, the same pattern portion as the pattern portion 200 formed on the inner surface of the container body 100 may be formed on the outer surface of the container body 100 .

Therefore, when holding the container by hand or placing the container on a wet floor by the pattern portion formed on the outer surface of the container body 100, the anti-slip effect of the container can be further improved.

The container body 100 includes 60 to 80 parts by weight of sugarcane pulp, 20 to 40 parts by weight of bamboo pulp, 1.0 to 1.1 parts by weight of an oil-resistant agent, and 1.5 to 2.2 parts by weight of a waterproofing agent.

The sugar cane pulp is obtained by crushing and bleaching the residue remaining after squeezing the sugar of sugar cane.

When the content of the sugar cane pulp is less than 60 parts by weight, it is difficult to uniformly disperse the oil-resistant agent and the waterproofing agent, and when it exceeds 80 parts by weight, strength and water resistance are deteriorated.

The bamboo pulp is obtained by heating chips obtained by cutting bamboo stems in a solution of water and chemicals to break down the fibers into a viscous pulp, and removing chemicals and suspended impurities when completely digested.

When the content of the bamboo pulp is less than 20 parts by weight, it is difficult to uniformly disperse the oil-resistant agent and the waterproofing agent, and when it exceeds 40 parts by weight, the strength is lowered and it is difficult to maintain the shape.

The oil-resistant and waterproofing agents are added to prevent oil or water from being torn or contaminated in a container.

When the content of the oil-resistant agent is less than 1.0 parts by weight, there is a problem in that oil resistance performance is significantly deteriorated, and when it exceeds 1.1 parts by weight, there is a problem in which the coating is incomplete.

Here, the oil-resistant agent includes 15 to 25 parts by weight of a fluoropolymer and 70 to 80 parts by weight of water based on 100 parts by weight of the oil-resistant agent.

When the content of the waterproofing agent is less than 1.5 parts by weight, there is a problem in that waterproof performance is lowered, and when it exceeds 2.2 parts by weight, there is a problem in that economical efficiency is lowered.

Here, the waterproofing agent includes 10 to 20 parts by weight of an acrylate copolymer and 80 to 90 parts by weight of water based on 100 parts by weight of the waterproofing agent.

The pattern part 200 is formed in a geometric pattern on the inner surface or upper circumferential surface of the container body 100 . Here, the geometric pattern refers to a pattern based on geometric elements such as straight lines, curves, and dots.

In particular, when the pattern unit 200 is formed on the inner surface of the container body 100, it may be formed on the entire inner surface or a part (bottom surface) of the container body 100.

2, 9 and 10, the pattern unit 200 formed on the inner surface of the container body 100 is any one of a chevron pattern, a herringbone pattern, and an embossing pattern. It is preferable to form one pattern.

In particular, the pattern portion 200 formed on the inner surface of the container body 100 may be formed on the whole or part of the inner surface of the container body 100 .

As described above, the pattern portion 200 formed on the inner surface of the container body 100 is formed in one of a chevron pattern, a herringbone pattern, and an embossed pattern, thereby reducing the contact area with rice contained in the container body 100, Accordingly, when unpacking the sticky rice contained in the container body 100, the grains of rice are easily separated from the container body 100, and the inner surface of the container body 100 is prevented from being torn in the process of dropping the rice grains. can

The pattern unit 200 is preferably arranged in any one of a linear direction, a cross direction, and an oblique direction.

On the other hand, it is preferable that the width and depth of the pattern portion 200 are 0.1 to 0.5 mm, respectively.

When the width and depth of the pattern portion 200 formed on the circumferential surface of the upper end of the container body 100 is less than 0.1 mm, the vinyl film 300 does not permeate well into the valleys between the pattern portions during sealing of the vinyl film 300, resulting in poor sealing. If this is not done properly and exceeds 0.5 mm, there is a problem in that the sealed vinyl film 300 easily falls off and the effect of sealing is reduced.

In addition, when the width and depth of the pattern portion 200 formed on the inner surface of the container body 100 are 0.1 to 0.5 mm, the contact area with the rice contained in the container body 100 is reduced, so that the rice grains when uncooking the rice. There is an effect of easily separating from the container body (100).

As shown in FIGS. 1, 2, 9 and 10, the pattern portion 200 formed on the upper circumferential surface of the container body 100 includes a chevron pattern, a herringbone pattern, embossing ( It is preferable to be formed with any one of the embossing patterns.

In addition, as shown in FIGS. 1 and 11, the pattern portion 200 formed on the upper circumferential surface of the container body 100 includes a transverse band pattern 210 formed of parallel line-shaped patterns and a longitudinal band The pattern 220 may be formed, but the transverse band pattern 210 and the longitudinal band pattern 220 may be alternately arranged.

12 and 13, the pattern portion 200 formed on the upper circumferential surface of the container body 100 includes a chevron pattern, a herringbone pattern, an embossed pattern, a transverse band pattern 210 and a longitudinal band pattern. When the vinyl film 300 is sealed by thermal fusion by forming one of the patterns 220 alternately arranged with each other, the vinyl film 300 permeates evenly and stably adheres to the vinyl film 300. This has the effect of not easily falling off.

As shown in FIG. 14, a plurality of protruding protrusions 110 may be formed around the outer surface of the container body 100 at regular intervals so that a plurality of containers can be easily separated individually in an overlapping state.

In this way, the protruding protrusion 110 is formed along the outer circumference of the container body 100 so that when a plurality of containers are stacked, the protruding protrusion 110 of the upper container is caught on the upper end of the lower container, so that the container By limiting the insertion depth of the stacked containers can be easily separated individually when discharged by gripping them.

Hereinafter, the present invention will be described in more detail by examples. However, the following examples are merely illustrative of the present invention, and the content of the present invention is not limited to the following examples.

Preparation Example 1: Manufacturing a disposable container

70 parts by weight of sugarcane pulp, 27 parts by weight of bamboo pulp, 1 part by weight of an oil resistant agent and 2 parts by weight of a waterproofing agent were added to a mixer and mixed. Subsequently, the mixture was put into a molding mold to prepare a disposable container having a geometric pattern pattern on the inner surface or upper circumferential surface. At this time, the width and depth of the pattern portion were each manufactured to a size of 0.5 mm.

Example 1

After the vinyl film was cut to a size suitable for the disposable container prepared in Preparation Example 1, the vinyl film was heat-sealed on the upper circumferential surface of the disposable container using a sealing packaging machine.

Comparative Example 1

A disposable container was manufactured in the same manner as in Preparation Example 1, except that the pattern portion was not formed on the upper circumferential surface of the disposable container when manufacturing the disposable container. Thereafter, in the same manner as in Example 1, an attempt was made to seal a vinyl film on the circumferential surface of the top of the disposable container, but the sealing of the vinyl film did not work well.

Comparative Example 2

A disposable container was manufactured in the same manner as in Preparation Example 1, except that the width and depth of the pattern portion formed on the upper circumferential surface of the disposable container were each 1 mm in size when manufacturing the disposable container. Thereafter, in the same manner as in Example 1, a vinyl film was heat-sealed on the circumferential surface of the upper end of the disposable container to seal it.

Test Example 1: Vinyl film peeling experiment of disposable container

Excluding Comparative Example 1, where the sealing treatment of the vinyl film is difficult, was excluded from the evaluation target, and a test of peeling off the vinyl film was conducted with 5 testers on the disposable containers in which the sealing treatment of the vinyl film was performed in the remaining Examples 1 and 2. (By dividing the evaluation items, 1 point: very weak adhesion, 2 points: adequate adhesion and appropriate force required for peeling, 3 points: strong adhesion, excessive force required for peeling, 4 points: strong adhesion and , Excessive force is required during peeling, and a 4-point scale method, which indicates tearing of the vinyl film, was used.)

evaluation criteria score Example 1 Comparative Example 1 Comparative Example 2 1 point

Exclusion from evaluation 5 people 2 points 5 people 3 points 4 points

As can be seen from Table 1, in the plastic film peeling evaluation of the disposable container, the disposable container of Example 1 in which the width and depth of the pattern portion are formed to a size of 0.5 mm, respectively, on the upper circumferential surface of the disposable container, the width of the pattern portion It was confirmed that the peel evaluation was relatively excellent compared to the disposable container of Comparative Example 2, each having a size of 1 mm and a depth of 1 mm.
