Description

Plastic Disposable Cup Lids {DISPOSABLE PLASTIC CUP LID}

The present invention relates to a cup lid, and more particularly, a synthetic resin configured to prevent a burn that may occur when drinking hot coffee, while preventing the beverage to be smoothly discharged through the intended route, and prevents spillage of the drink due to carelessness. The invention relates to a disposable cup lid.

Coffee shops often use mugs to sell drinks, but disposable cups are frequently used to take them out of the store.

Disposable cups are usually formed of paper or synthetic resin material, the upper portion of the disposable cup is used in combination with a cup lid for preventing the outflow of the beverage.

Recently, a cup lid used for a disposable cup is provided with a portion for drinking a drink and a portion for drinking by inserting a straw while the human mouth is in contact.

Since the lid of a cup for packaging hot coffee is formed of an opaque colored synthetic resin material, attention is required especially when drinking hot coffee because the beverage inside is not visually confirmed.

In addition, the guide fence 130 is protruded and formed in the vicinity of the drinking hole 120, and the guide groove 130 is formed in the guide fence 130 to guide the outflow of the beverage.

In order to drink coffee, the cup and the lid must be tilted in a state where the guide fence 130 is covered with a mouth.

By the way, the drinking hole 120 for spilling the coffee is formed in a position spaced apart from the lower end 132 of the guide fence 130 in contact with the mouth of the person.

In such a state, when the cup and the lid are inclined so that the coffee flows out from the drinking hole 120, the coffee is first introduced into the interior space S of the guide fence 130, and the coffee is then guide fence 130. It may not flow out to the drinking hole 120 until it flows over the inner wall 131.

However, since the coffee flows out through the drinking hole 120 in a kind of flooding state beyond the inner wall 131 of the guide fence 130, the coffee flowing through the inner wall 131 is the drinking hole 120 Can inadvertently release a large amount at a time.

Since the cup and the cup lid are inclined while the mouth of the person is in contact with the end of the guide fence 130, it is the guide fence 130 and its inner wall 131 that can sense the degree of sensory tilting. Ball 120 is difficult to determine the degree of inclination can not be seen with the eye.

This is because the drinking hole 120 is not formed in the extension line of the inner wall 131 of the guide fence 130, but the drinking hole 120 is formed spaced apart from the inner wall 131 or the extension line.

For this reason, in order to prevent inadvertently spilling a large amount of hot coffee through the drinking hole 120, people instinctively tilt the cup very carefully, and sometimes the coffee in a hot state unintentionally spills a large amount Rather than flowing along the guide groove 135, a drop occurs directly to the drinker's lips.

On the other hand, in the cup lid coupling portion 140 is formed to surround the upper curling portion 210 of the cup body 200, the coupling force of the coupling portion 140 and the curling portion 210 is more than necessary There is a strong case.

In some cases, the user may want to drink a beverage in a state in which the lid is separated from the cup body 200. When the coupling force between the coupling part 140 and the curling part 210 is very strong, the lid is separated. Due to the applied force, the beverage inside the cup body 200 is spilled.

This may cause burns, especially if the beverage is hot coffee.

Referring to Figure 3, the synthetic resin disposable cup lid according to the present invention is formed on the base portion 10 and the edge of the base portion 10 is formed in the center of the cup lid from the top of the cup to the upper end of the cup 90 Coupling portion 20 to be coupled, the beverage induction portion 30 is formed in the ridge between the base portion 10 and the coupling portion 20 on one side of the base portion 10, and formed near the beverage induction portion 30 The beverage outlet hole 40 and the straw inserting portion 50 is formed to face the beverage induction portion 30 on the other side of the base portion 10, the beverage induction portion 30 in the base portion 10 And a step 2 is formed in an area between the straw inserting portion 50, and the straw inserting portion 50 has a straw inserting opening 51 and an opening and closing portion 60 for opening and closing the straw inserting opening 51. Is formed, between the beverage outlet 40 and the beverage induction portion 30, the induction protrusion 42 is melted in the base portion 10 It is characterized in that the formation.

The cup may be formed of paper or synthetic resin, and the cup lid is formed of synthetic resin.

The cup lid is mainly used to open and close the upper portion of the paper cup used for packaging drinks or coffee at a beverage store or coffee shop.

The base portion 10 is a portion forming the bottom surface of the cup lid, and is formed in a substantially circular shape on a flat cross section so as to correspond to the upper edge portion of the cup.

The coupling part 20 is in contact with the upper edge portion 92 of the cup 90, and is coupled to the cup 90.

The front of the base portion 10 is formed in the beverage induction portion 30 to guide the beverage to the user's mouth is raised.

The beverage drinker is in contact with the mouth of the upper end of the beverage induction portion 30, and tilts the cup 90 to consume the beverage.

A beverage outlet hole 40 is formed in the vicinity of the beverage induction part 30, and the beverage spilled through the beverage outlet hole 40 flows along the beverage induction part 30.

A straw insertion portion 50 for inserting a straw is formed at a position facing the beverage induction portion 30 at the other side of the base 10.

In general, a step 2 is formed in the area between the beverage induction part 30 and the straw inserting part 50 in the base part 10, and is configured to form and arrange information such as a logo.

The straw inserting portion 50 is formed with an opening and closing portion 60 for opening and closing the straw insertion opening 51, a concave portion 70 for inserting the opening and closing portion is formed on the opposite side of the straw inserting portion 50. do.

Thus, the straw insertion opening 51 is opened in a state where the opening and closing portion 60 is fixed by lifting the opening and closing portion 60 and inserting the opening and closing portion 60 into the recessed portion 70 formed on the opposite side.

When the straw is not used, the opening and closing part 60 is separated from the recess 70 and positioned again into the straw inserting part 50 so that foreign matter such as dust is transferred to the straw inserting opening 51. Prevent entry.

In order to be able to lift the opening and closing portion 60 from the straw insertion opening 51 as described above, the straw insertion portion 50 is formed with a cut line 52 as a separation line.

In the cup lid according to the present invention, between the beverage outlet hole 40 and the beverage induction portion 30, the base portion 10 is formed by the induction protrusion 42 is raised.

The guide protrusion 42 is formed by deforming the base 10, and is formed in the form of a pleat including the peak 424 and the valley 422.

Thus, the induction protrusions 42 formed in the form of wrinkles as described above have a larger surface area and have a larger capillary force than in the case of being formed flat.

Thus, the beverage spilled through the beverage outlet hole 40 is more smoothly guided toward the beverage induction part 30 through the bone portion 422 formed in the guide protrusion 42.

In addition, since the induction protrusion 42 is formed in the shape of wrinkles, the induction protrusion 42 has a wider surface area than the case where it is formed flat, so that hot coffee flows through the induction protrusion 42. It may be cooled somewhat by heat transfer through 424 to prevent burns on the lips.

In addition, since the coffee is dispersed by the acid portion 424 and the bone portion 422 during the flow of the coffee flows toward the beverage induction part 30, the aroma of the coffee can be more actively scattered to the nose of the drink, drinking of coffee You can feel the aroma richer.

As shown in FIG. 5, the induction protrusion 42 is formed to be inclined downward toward the beverage outlet hole 40.

Thus, coffee remaining in the bone portion 422 of the guide protrusion 42 in the drinking process can be flowed back toward the beverage outlet 40 to fall, thereby preventing the flow into the base 10. can do.

Thus, it is possible to prevent the base portion 10 from being dirty by the residual coffee generated during the drinking process.

In addition, the cutout line 52, which is a boundary line between the opening and closing part 60 and the straw insertion opening 50, is formed in a waveform.

If the cut line 52 is formed in a straight line, it is partially between the lower edge portion 61 of the opening and closing portion 60 constituting the cut line 52 and the edge portion forming the straw insertion opening 51. Space may be generated or excitation may occur.

That is, when the opening and closing part 60 is inserted into the concave part 70 once and then separated from the concave part 70 to the original position by the straw insertion opening 51, the opening and closing part 60 and the base part ( By the restoring force of the boundary portion (the portion where the cut line 52 is not formed) between the 10), the lower edge portion 61 (the cut line 52 portion) of the opening and closing portion 60 is removed from the straw insertion opening 51. Frequent or spaced phenomenon occurs frequently.

In order to prevent such a phenomenon, even when a force is applied so that the lower edge portion 61 is excessively pressed into the straw insertion opening 51 by inserting the edge portion 61 and the straw insertion portion too much. Space is created between the edge portions of the opening 51.

However, by forming the cutout line 52 in a wave form, the probability that the lower edge portion 61 of the opening and closing portion 60 and the edge portion forming the straw insertion opening 51 may interfere with each other.

That is, when positioning the opening and closing part 60 to the original straw insertion opening 51, when any part of the cut line 52 formed in the waveform as described above interfere with each other, the opening and closing part 60 is the original position It can act as a fixed force, the lifting space 52 may be smaller than the lifting space compared to the case formed in a straight line.

Thus, when the opening and closing part 60 is inserted into the recess 70 and returned to its original position, foreign matters such as dust can be prevented from flowing through the perforated line 52, and the cup is rained. When intentionally tilted, it is possible to reduce the amount of the beverage flowing out through the space of the perforated line 52.

Meanwhile, in the second embodiment of the present invention according to FIG. 4, two contact protrusions 722 are formed at the side portion 72 that is in contact with the opening and closing part 60 at the recess, such that the two contact protrusions ( 722 are each configured to be in contact with the side of the opening and closing part 60.

By forming the two contact protrusions 722 to be in contact with the side of the opening and closing part 60, when the opening and closing part 60 is inserted into the recess 70, the side of the opening and closing part 60 is in contact. The area to be minimized can be minimized.

In the conventional cup lid in which the two contact protrusions 722 are not formed, the side portions of the opening and closing portions 60 are in contact with the entire surface of the side portion 72 contacting the opening and closing portions 60 at the recesses. (Fitting contact).

In this state, the coupling force between the opening and closing portion 60 and the recessed portion 70 (exactly, the side portion 72 of the recessed portion) becomes excessive, and the opening and closing portion 60 is separated from the recessed portion 70 to its original position. There is a case where a large force is required to return.

In this case, an excessive force is applied to the opening and closing part 60, so that the drinker's hand is injured by the lower edge portion 61 of the opening and closing part 60, or the beverage inside the cup 90 flows to the If the flow through the beverage outlet 40 or the straw insertion opening 50 is generated.

In order to prevent this phenomenon, the spacing between the two side portions 72 of the recess 70 must be manufactured very precisely.

However, by forming the contact protrusions 722 on the side surface portion 72 as described above, the side surface of the opening and closing portion 60 is in contact with the contact protrusion 722 in a kind of point contact state, thereby significantly reducing the contact area Coupling force acting on the side of the opening and closing part 60 may also be reduced.

Thus, the opening and closing part 60 can be inserted into the concave part 70 to fix the position, and the concave part 60 can be easily recessed with a smaller force when the opening and closing part 60 is to be removed and returned to its original position. It can be separated from the unit 70.

Further, as shown in FIG. 5, the bottom portion 74 of the recess 70 is raised so that the center portion is raised so that the opening and closing portion 60 can be applied with a restoring force when the opening and closing portion 60 is separated from the recess 70. Can be formed.

Thus, when the opening and closing portion 60 is inserted into the recess 70, the raised portion of the bottom portion 74 in which the central portion is raised is deformed, and the opening and closing portion 60 is separated from the recess 70. In this case, since the deformed bottom portion 74 exerts an elastic force to be returned to its original shape, the opening and closing portion 60 can be more easily separated from the concave portion 70.

In view of this, in the third embodiment of the present invention shown in FIG. 6, the opening and closing portions are formed in the form of two protrusions 60-1 and 60-2 spaced apart from each other.

By removing the central portion 62 of the opening and closing portion 60 in comparison with the embodiment shown in FIGS. 3 and 4, the two protrusions 60-1, 60-2 are directed toward the central portion 62. Can be flowed to a degree.

Thus, when the opening and closing portion 60 is inserted into the recess 70, the two protrusions 60-1 and 60-2 flow toward the central portion 62, whereby the opening and closing portion 60 is formed. Is more easily coupled to the recess 70, and can be easily separated from the recess 70.

On the other hand, in the embodiment shown in Figure 6, 7, the cooling projection 32 is formed on the surface of the beverage induction portion 30 facing the beverage outlet 40.

In the embodiment shown in Figure 6, the plurality of cooling projections 32 is formed in the form of a line along the horizontal direction, in the embodiment shown in Figure 7 is formed in the form of irregularities.

The cooling protrusion 32 is also formed by deforming the synthetic resin material forming the beverage induction part 30, the surface area of the portion of the beverage induction part 30 is increased by the cooling protrusion 32.

Thus, the hot coffee flowing through the cooling projection 32 can be cooled somewhat, and the coffee aroma can be scattered more actively.

8 and 11, the beverage outlet 40 is formed below the inner surface 301 of the beverage induction part 30.

The drinker tilts the cup in a state where the drink is put on the upper end of the beverage induction part 30 and drinks the beverage.

Typically, the lid of a cup for packaging hot coffee is formed of an opaque colored synthetic resin material, it is not possible to visually check the beverage inside.

However, since the cup is tilted in the state where the drink is put on the drink induction part 30, the drinker senses the inclination degree of the drink induction part 30 and its inner surface 301.

When the cup is inclined as shown in FIG. 10, the beverage 300 in the cup is first filled in the space S inside the beverage induction part 30, and then flows out through the beverage outlet 40. Through the sensation of the lips in contact with the beverage induction unit 30 can feel whether the hot coffee is filled in the beverage induction unit 30, and also detects the degree of inclination of the inner surface 301 of the beverage induction unit 30. can do.

Therefore, by forming a beverage outlet hole 40 in the lower inner surface 301 of the beverage induction portion 30, even in the case of hot coffee drinking to prevent accidentally suddenly a large amount of coffee flowing through the beverage outlet hole can do.

As shown in Figure 9, 10, the inner surface of the beverage induction portion 30 may include two inclined surfaces (30-1, 30-2) formed at different angles on the side cross-section.

In FIG. 9, the lower inclined surface 30-1 of the two inclined surfaces is formed at a larger angle with respect to the horizontal line than in the upper inclined surface 30-2.

Thus, when the cup is inclined as shown in FIG. 10, the beverage slowly flows first through the lower inclined surface 30-1, which becomes more gently inclined relative to the horizontal line, and then the upper inclined surface 30-2 having a larger inclination. Flows into.

The drinker is in a state in which the lips are in contact with the beverage induction part 30, so that when hot coffee is spilled onto the lower inclined surface 30-1, it can be sensed.

Thus, compared to the case where the inner surface 301 of the beverage induction part 30 is formed as a single inclined surface, the hot coffee is somewhat cooled in the process of slowly flowing along the lower inclined surface 30-1 of the gentle inclination. In order to allow the fluid to flow to the lips of the drinker, the drinker can also sensibly adjust the degree of tilting the cup to prevent burns.

8 to 11, a cooling protrusion 32 is formed on the upper surface 30-2 of the inner surface 301 of the beverage induction part 30, and the beverage outlet hole is provided on the lower surface 301. 40 is formed.

In the above embodiment, the beverage outlet 40 is formed in plurality in the height direction in the form of an opening cut into an approximately long rectangular shape, it is configured to increase the surface area of the portion of the beverage outlet 40.

Thus, the hot coffee is discharged through the beverage outlet hole 40 formed of a plurality, it can be cooled slightly during the coffee spill process, it is configured to actively scatter the coffee aroma.

In the embodiment shown in Figure 11, the beverage outlet 40 is formed in the form of a plurality of openings which are inclined with respect to the vertical direction.

Thus, compared to the case in which the beverage outlet 40 is formed in the vertical direction, the length of the beverage outlet 40 is increased, and the surface between the beverage outlet 40 is further increased, thereby cooling and scattering the coffee flavor. The effect can be further enhanced.

On the other hand, as shown in Figure 12, on the inner surface of the coupling portion 20, a pair of coupling protrusions 22 may be formed along the coupling portion 20 is formed in a circular plane on the plane.

When the coupling protrusion 22 is not formed, as in the conventional cup lid, the upper edge portion 92 of the cup 90 and the inner surface of the coupling portion 20 is in a surface contact state.

The edge portion 92 and the coupling portion 20 may be in a state of being strongly coupled or not coupled to each other, to prevent the coupling portion 20 from being coupled to the edge portion 92. To this end, the coupling portion 20 of the cup lid is typically formed to be coupled with a rather strong bonding force.

Due to these factors, when the coupling portion 20 and the edge portion 92 are brought into surface contact as described above, excessive force is sometimes required when the cup lid is to be removed from the cup 90. In the process of strongly grasping the 90 and removing the lid, a drink is poured into the cup.

Therefore, by forming a pair of coupling protrusions 22 on the inner surface of the coupling portion 20 along the inner surface of the coupling portion, the coupling protrusion 22 and the edge portion 92 when the edge portion 92 and the cup lid are coupled to each other. ) Can be a kind of point contact, reducing the contact area and bonding force.

Thus, as compared with the case where the coupling protrusion 22 is not formed, management of the tolerances required for manufacturing the cup lid is facilitated, and the coupling protrusion 22 can secure the coupling force between the cup lid and the cup, If necessary, the separation can be easily performed with little force.

As mentioned above, although the present invention has been described by way of limited embodiments and drawings, the technical idea of the present invention is not limited thereto, and a person having ordinary skill in the art to which the present invention pertains, Various modifications and variations may be made without departing from the scope of the appended claims.
