Description

Double-Layered Cup Set}

The present invention relates to cups and bottles, and more particularly to double-layer cup sets.

Vacuum containers (thermos) contain a bilayer to keep the heat inside. Thus, the bilayer structure keeps the liquid warm or cool for extended periods of time, allowing the user to be in a state of burn.

Conventional vacuum vessels include an inner cylinder and an outer cylinder. The outer cylinder is made of stainless steel. The inner cylinder is made of glass and is coated with a reflector layer, such as silver or mercury, to reflect the heat radiation and return it to the interior to conserve heat.

Other conventional vacuum vessels include an inner cylinder, an outer cylinder, and a gap between the inner cylinder and the outer cylinder. Typically, the inner cylinder and the outer cylinder are made of stainless steel. Air is pumped out of the gap to cause the gap to become vacuum. Thus, the gap prevents air from conducting heat.

Other conventional vacuum vessels, as disclosed in TW M405221, are made in a bilayer structure. The bilayer structure includes an inner cylinder, an outer cylinder, and a gap between the inner cylinder and the outer cylinder. Since the inner cylinder and the outer cylinder are made of the same polymer such as plastic, they can be joined together by high-frequency welding.

However, the appearance of these conventional flasks is monotonous and boring.

Therefore, the present invention is intended to eliminate or at least alleviate the problems encountered in the prior art.

The purpose of the present invention is to provide a set of double-layer cups which are colorful and heat-conserving.

To achieve the above object, the double layer cup set includes an outer cylinder, an inner cylinder, and a sealing ring. The outer cylinder is formed with an open upper end. The inner cylinder is formed to have an open upper end and is inserted into the outer cylinder through the open upper end of the outer cylinder. There is a gap between the outer cylinder and the inner cylinder. The seal ring is inserted into the gap such that the seal ring seals the gap.

Other objects, advantages and features of the present invention will become apparent from the detailed description provided with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS The present invention will now be described in detail with reference to the accompanying drawings, in which:

Figure 2 is a partial cross-sectional view of the dual-layer cup set shown in Figure 1;
Figure 3 is an enlarged view of a dual layer cup set according to a second embodiment of the present invention;
Figure 4 is a partial cross-sectional view of the dual layer cup set shown in Figure 3;
5 is a partial cross-sectional view of a dual layer cup set according to a third embodiment of the present invention;
6 is a partial cross-sectional view of a dual layer cup set according to a fourth embodiment of the present invention.

Referring to Figures 1 and 2, a dual layer cup set 10 includes a cap 20, an outer cylinder 30, and an inner cylinder 40 in accordance with a first embodiment of the present invention. The cap 20 includes a thread (not shown) extending over the inside.

The outer cylinder 30 is transparent formed with the upper end 32 and lower end 34. Two recesses 36 are made inside the outer cylinder 30 near the upper end 32. The recess 36 is a slot extending in the radial direction through the outer cylinder 30. However, the recess 36 may be a groove, an arcuate slot, a bore or an opening in another embodiment. A non-slip structure (not shown) may be formed on the outer side of the outer cylinder 30. The upper end 32 is of course an open end. The lower end 34 is preferably a closed end. However, the lower end 34 may be an open end in other embodiments.

The inner cylinder 40 is translucent formed with the upper end 42 and the lower end 44. The upper end 42 is, of course, an open end which can be filled with liquid or poured out of the inner cylinder 40. The lower end 44 is of course a closed end. The inner cylinder 40 further includes a seal ring 48 and a connecting portion 46. The seal ring 48 extends over and around the inner cylinder 40 near the upper end 42. The seal ring 48 and the inner cylinder 40 are preferably made of one. However, the seal ring 48 may be manufactured independently of the inner cylinder 40 in other embodiments.

The two protrusions 41 extend radially from the seal ring 48. The projecting portion 41 has a cubic shape along the concave portion 36. However, the protrusion 41 may be a barb in another embodiment. The connecting portion 46 includes a thread (no number) for fastening by a thread of the cap 20 on the outside.

The inner cylinder 40 is included in the outer cylinder 30. The projecting portion 41 is inserted into the recess 36 to hold the inner cylinder 40 in the outer cylinder 30.

When the inner cylinder 40 is inserted into the outer cylinder 30, the volume of the gap 12 is reduced. The pressure of the air in the gap 12 increases so as to prevent the inner cylinder 40 from being inserted into the outer cylinder 30 when air is introduced into the gap 12. [ The recess 36 is used as a channel through which air is discharged from the gap 12 to avoid increasing the pressure of the air in the gap 12 to facilitate the insertion of the inner cylinder 40 into the outer cylinder 30 . A sealing material such as glue is preferably filled in the recess 36 after the protrusion 41 is inserted into the recess 36. [

The projecting portion 41 is compressed by the outer cylinder 30 as the projecting portion 41 moves toward the concave portion 36 through the upper end portion 32. The protrusion 41 expands when it enters the concave portion 36. The seal ring 48 and the projection 41 are made to have a greater thickness than the other portions of the inner cylinder 40. [ The projections 41 are made to have appropriate strength while the projections 41 are compressed and expand appropriately in the recesses 36 to effectively retain the inner cylinders 40 in the outer cylinders 30.

The seal ring 48 is manufactured to have an outer diameter larger than the inner diameter of the outer cylinder 30 near the upper end 32. The seal ring 48 therefore strongly urges on the outer cylinder 30 near the upper end 32 to seal the gap 12 between the inner cylinder 40 and the outer cylinder 30. Thus, the liquid can not easily enter the gap 12.

Preferably, the seal ring 48 is made to have a thickness (W) of 0.5 to 30 millimeters. The thickness (W) is greater than 0.5 millimeter, thus providing a sufficient sealing effect. The thickness W is less than 30 millimeters to ensure smooth insertion of the inner cylinder 40 into the outer cylinder 30. [

The color of the inner cylinder 40 can be seen through the transparent outer cylinder 30. Thus, the appearance of the double-layer cup set 10 is colorful and aesthetically pleasing. Further, the amount of liquid in the inner cylinder 40 can be observed through the outer cylinder 30.

3 and 4, there is provided a dual layer cup set 10 according to a second embodiment of the present invention. The second embodiment is the same as the first embodiment except for a few features. First, the concave portion 36 and the protruding portion 41 are obtained. The seal ring 48 simply fits into the outer cylinder 30 near the upper end 32. [ Second, the recess 50 is made inside the outer cylinder 30 at the upper end 32. As discussed above, the volume of the gap 12 is reduced, and air enters the recess 36 when the inner cylinder 40 is inserted into the outer cylinder 30. The concave portion 50 is used as a channel through which air is discharged from the gap 12 in the direction indicated by the arrow head shown in Fig.

Referring to Figure 5, there is provided a dual layer cup set 10 according to a third embodiment of the present invention. The third embodiment is the same as the second embodiment except for some features. First, the seal ring 48 is made to have a thicker thickness W of 0.5 to 30 millimeters. Second, the outer cylinder 30 is not manufactured to have a recess for discharging air. Third, the annular recess 54 is fabricated in the seal ring 48 of the inner cylinder 40. The annular recess 54 is used as a channel through which air is discharged. Fourth, the sealing material is provided between the seal ring 48 and the outer cylinder 30. The sealing material may be a grease or an adhesive for improving the airtightness between the sealing ring 48 and the outer cylinder 30. [

Referring to Fig. 6, there is provided a dual layer cup set 10 according to a fourth embodiment of the present invention. The fourth embodiment is the same as the first embodiment except that the projecting portion 41 is manufactured independently of the seal ring 48. [ The protrusion 41 is formed on the outer side of the inner cylinder 40 on the seal ring 48. Similarly, the protrusion 41 extends in the recess 36 to hold the inner cylinder 40 in the outer cylinder 30 while the seal ring 48 pushes the outer cylinder 30 in the gap 12, .

The design is described through a detailed description of the embodiments.

Skilled artisans may derive modifications from the embodiments without departing from the scope of the present invention. Accordingly, the embodiments do not limit the scope of the present invention as defined in the claims.
