Abstract
The disposable paper cup has a body formed of a cylindrical wall with a recess at the top. The portions of the body wall adjacent either side of the recess are aligned into a flap. The flap is folded over and secured to the exterior surface of the body wall to entirely enclose the cup body, except for an integral spout formed by the recess.
Description
- Priority is claimed on Provisional Patent Application Ser. No. 62/732,557, filed Sep. 17, 2018, which is incorporated herein in its entirety by reference.
- Not Applicable
- Not Applicable
- The present invention relates to a paper cup and more particularly, to a paper cup with a wall which is folded to form a spout and needs no lid.
- Conventional paper cups for hot or cold beverages have a large open top and require a separate lid to close the cup. The lid adds another element to the production, delivery and storage cost.
- Aside from the cost, closing the cup with a separate lid can create problems. If the user squeezes the cup, the internal pressure can cause the lid to pop up, allowing the liquid in the cup to spill.
- Separate lids for paper cups are not good for the environment. The lids are often made of plastic which is not biodegradable. The lids add to the waste which must be disposed of and accumulate in garbage dumps.
- Accordingly, there is a need for a low cost, safe, environmentally friendly and elegant paper cup for hot and cold drinks which can be used for personal and commercial use, which has an integral spout and does not require a separate lid.
- Moreover, in certain situations, such as where the liquid in the cup is to be consumed which the user is in motion or has only one hand available to hold the cup, it may be difficult for the user to obtain the liquid from the cup without spilling a portion of the liquid.
- There is, therefore, also a need to have a cup which can be used by one hand and has an integral spout through which liquid can easily flow into the mouth of the user, without having to remove a lid or use a straw.
- In accordance with one aspect of the present invention, a disposable paper cup is provided having an entirely enclosed body except for an integral spout.
- In accordance with another aspect of the present invention, a disposable paper cup is provided. The cup has a body formed of a generally cylindrical wall. A recess is created at the top of the body. The portions of the wall adjacent the recess are folded over to entirely enclose the body, and define the spout formed by the recess.
- The wall portions are aligned in side-by-side relation prior to being folded. The folded portions are sealed to the body after being folded.
- An insulating sleeve may be provided surrounding the cup body.
- In accordance with another aspect of the invention, a method of forming a disposable paper cup body is provided. The cup body is formed of a generally rectangular paper sheet part having a top edge and opposite sides. The method comprises the steps of: creating a recess in the sheet part adjacent the top thereof; sealing the sides of the part to form a generally cylindrical body; aligning the portions of the body on either side of the recess; moving the aligned portions of the body together into side-by-side relation; folding the aligned portions to a position adjacent the exterior surface of the cup body such that the recess forms a spout; and sealing the aligned portions to the exterior of the cup body.
- The method further includes the steps of: creating a generally cylindrical sleeve of heat insulating material; and inserting the cup body into the sleeve.
- To these and to such other objects that may hereinafter appears, the present invention relates to a paper cup as described in detail in the following specification and recited in the annexed claims, taken together with the accompanying drawings, in which like numerals refer to like parts and in which:
-
FIG. 1 is an elevation view of a paper sheet which has been cut to create paper portions which will form the bottom and side wall of the paper cup; -
FIG. 2 is a perspective view of the paper cup after side wall has been formed and the bottom attached; -
FIG. 3 is a side elevation view of the paper cup showing the portions to be folded aligned and in side-by-side relation; -
FIG. 4 is a side elevation view of the paper cup with the aligned portions folded; -
FIG. 5 is a side elevation view of the cup ofFIG. 4 with the optional insulating sleeve exploded; -
FIG. 6 is a side elevation view of the cup ofFIG. 4 showing the location at which the folded portions are sealed to the exterior surface of the cup wall; and -
FIG. 7 is a side elevation view of the cup ofFIG. 3 showing the sealing points. - As seen in the Figures, the present invention is a disposable paper cup which has an entirely enclosed body, except for an integral spout. The body is formed of a generally cylindrical wall with a top portion having a recess. The portions of the body wall adjacent the recess are folded over to entirely enclose the body, other than the spout formed by the recess.
- The body wall portions are aligned in side-by-side relation prior to being folded. The folded portions are sealed to the body after being folded. The cup may further include an insulating sleeve.
- The cup is formed from a sheet of paper. As seen in
FIG. 1 , the paper sheet is cut into a generally rectangular part, which will form the wall of the body of the cup and a circular part, which will form the bottom of the cup. - In the preferred embodiment of
FIG. 1 , the generally rectangular part actually has somewhat arcuate top and bottom edges such that when the body of the cup is formed, as seen inFIG. 2 , it is not exactly cylindrical but instead is generally cylindrical, being somewhat larger at the top than at the bottom. Thus, the resulting cup body is technically a truncated cone, which is a common shape for drinking cups and glasses. - For purposes of this disclosure, the term “generally rectangular” is intended to include rectangular shapes, and shapes which are approximately rectangular such as the shape of the part depicted in
FIG. 1 . Similarly, the term “generally cylindrical” is intended to include shapes which are cylindrical, and shapes which are approximately cylindrical such as the shape of the cup body as seen inFIG. 2 . -
FIG. 1 shows that the generally rectangular body part includes an upper left-hand portion 1 defined by afold line 2.Fold line 2 extends from the left side of the part to the top edge of the part and partially defines the top edge of acentral portion 3. Arecess 4 is situated at the top ofcentral portion 3 and has a semi-circular shape with corners at each side. - The left corner of
recess 4 is aligned withfold line 2. Asecond fold line 5 extends from the right side of the part to the other corner ofrecess 4 and defines the upper right-hand portion 6 of the part. In the preferred embodiment,fold lines - When the left side of the part and the right side of the part are sealed together to form the body of the cup, and the
circular part 7 is sealed to the bottom of the cup body, the partially formed cup appears as seen inFIG. 2 . - As seen in
FIG. 3 , whenportions recess 4 are aligned and moved into side-by-side relation to form a flap, the partially formed cup appears as illustrated inFIG. 3 . The flap formed ofportions fold line 2 such that it is adjacent the exterior of the surface of the cup body, and the partially formed cup appears as seen inFIG. 4 . In that state, the spout is defined byrecess 4 and the entire body of the cup, with the exception of the integral spout, is enclosed, eliminating the necessity for a separate lid. -
FIG. 5 shows a separateinsulating sleeve 9 into which the body of the cup of the present invention may be received.Sleeve 9 may also be formed of paper. The use ofsleeve 9 is optional and primarily employed when the cup contains hot beverages. However, in certain instances, the sleeve may be sized for used to secure the flat to the exterior of the cup body, eliminating the need for sealant or other securing means. In addition, an elastic band may be substituted for the paper sleeve by placing the band around the folded flap and the cup body. -
FIG. 6 illustrates theplace 10 where the folded flap formed byportions sleeve 9 or elastic band referred to above) may be used for sealing the flap to the cup body.FIG. 7 illustrates theplaces portion 1, respectively, which may be secured together. - In some situations, the flap formed by
portions - While only a single preferred embodiment of the present invention has been disclosed for purposes of illustration, it is obvious that many modifications and variations could be made thereto, including, for example, the size and shape of the cup body. It is intended to cover all of those modifications and variations which fall within the scope of the present invention, as defined by the following claims:
