The specific embodiment

At first referring to Fig. 1-Figure 10, on the one hand, the disclosure relates to a kind of container 10 with sidewall 12 and collapsible closure member or lid 14, and sidewall 12 and collapsible closure member or lid 14 form by integral type blank 16 (Fig. 2).On the other hand, in conjunction with Figure 11-Figure 13 the tube-in-tube structure that the disclosure relates to is described.

Fig. 1-Figure 10

If desired, sidewall 12 also can be used for providing bottom or other confining surface relative with lid 14.But,, preferably use independent blank 20 that bottom 18 is provided in order to provide bottom 18 to container 10 so that container 10 is supported on the straight orientation.It should be understood that blank 20 or other are used to form bottom 18 structure and can be included in the blank 16, to form the container of making by single blank.Equally, can use a plurality of blank area and make it to engage.In addition, although, it should be understood that alternately these containers can be reusable in conjunction with providing the preferred implementation of disposable container to be described.

Referring to Fig. 2, blank 16 is integral type blanks of being made by folding sheet material (such as this class paper board material that is commonly used to make dixie cup).Blank 16 can be made by other sheet material, comprises these class plastics that are used for making plastic cup.Blank 16 described here is configured for container 10 is made the shape of goblet.But, it should be understood that container 10 (so blank 16) also can manufacture other shapes, yet still have collapsible sealing member 14 structures of expectation.For example, container 10 can be configured to that sidewall is provided and be roughly the structure of square or rectangle.These containers can be suitable for various uses, such as supply and storage consumable store and nonexpendable item.

For the sidewall 12 that makes container 10 forms cylindrical-conical structure substantially, blank 16 be configured as have root edge 22, upper limb 24 and a pair of relative lateral margin (side margins) 26 and 28.Root edge 22 and upper limb 24 be bow upwards preferably, that is, root edge 22 is towards upper limb 24 bows, and upper limb 24 is similarly away from root edge 22 and bow abreast with it.

Lateral margin

26 and 28 is linear and extends to upper limb 24 from every end of root edge 22.But the length of root edge 22 is less than the length of upper limb 24, thereby

lateral margin

26 and 28 is uneven.Therefore, when blank 16 forms containers 10, when

lateral margin

26 and 28 when overlapping, the similar taper shape of the shape of sidewall 12.Dotted line 30 representatives opposite side overlapping areas when blank is rolled into taper shape on the blank 16.Zone between edge 26 and the line 30 also can comprise adhesive or adhesives, where necessary overlapping part is sealed together.But, in this, it should be understood that and can use conventional cup manufacturing technology and equipment that

edge

26 and 28 is carried out engaged and sealing.

For collapsible closure member or the lid 14 that expectation is provided, the section construction of the contiguous upper limbs 24 of blank 16 becomes to comprise to be roughly longitudinally folding line line segment 32a-32f, is roughly horizontal folding line line segment 34a-34f and angled folding line line segment 36a-36h.Desirably, folding line line segment use described here is commonly used to make this class automated machine of cardboard or other sheet material blanks and forms, and after this, container 16 uses and is commonly used to blank is transformed into this class automated machine of container and form.

Folding line line segment 32a-32f, 34a-34f, 36a-36h match and lid 14 can be formed as Fig. 1 and Fig. 7-sealing orientation shown in Figure 9, to form relative and to be roughly horizontal cap 38a-38b and at the relative and cap 40a-40b that be roughly chevron between horizontal cap 38a and the 38b.The chevron cap 40a of osed top lid and 40b aim at linearly and are adjacent to each other with end to end relation, and laterally

cap

38a and 38b aim at and each other linearly in abutting connection with the opposite side of chevron cap 40a and 40b.It should be noted that laterally cap 38a abuts against the side of two

chevron cap

40a and 40b, laterally cap 38b abuts against the opposite side of chevron cap 40a and 40b.Therefore, keep sealing the integraty in orientation by backfall with the orientation that cooperates of transverse part.

As used herein, term " is roughly laterally " should be understood to and is meant that

cap

38a and 38b substantially transversely locate with respect to sidewall 12.Therefore, although

cap

38a and 38b can have slight curving surface or plane surface, when lid 14 was assembled into cardinal principle closed container 10, each cap all kept horizontal substantially with respect to sidewall 12.Term " is roughly chevron " and should be understood to and is meant that

cap

40a and 40b comprise and is roughly leg-of-mutton lug boss.

Folding line line segment 32a-32f is orientated the length that is in substantially parallel relationship to blank 16 and the

lateral margin

26 and 28 of blank 16.Each folding line line segment 32a-32f extends to one of lateral fold line segment 34a-34f from upper limb 24 and intersects.Preferably, folding line line segment 32a-32f is formed in linear folding line or the crease of being roughly on the blank 16, and this folding line is made into outside the adjacent material portion that the folding line line segment is orientated be positioned at blank 16.

Folding line line segment 34a-34f is orientated the width that is in substantially parallel relationship to blank 16 and the root edge 22 and the upper limb 24 of blank 16.The line segment that folding line line segment 34a-34f forms the upper limb 24 that makes blank 16 extends towards the center of container 10 substantially.As directed, line segment 34a-34f is the basic fan-shaped or arc folding line that is, still, it should be understood that these line segments also can be linear folding lines.Preferably, line segment 34a-34f uses arc folding line to provide extra aesthetic appearance feature to lid 14, and basic curved surface 42 and 44 can be provided on lid 14, notice that these surface energies provide comfortable surface for user's mouth when container 10 is used as goblet.In this, for the ease of the beverage in the drinking container 10, expectation provides punch position, this punch position can be removed to form slit or hole 46 on one or two in 22 or 24 of surface.In addition, punch position can be arranged to have and be configured to the hole 48 passed for suction pipe etc.

Preferably, each all is linear folding line among the folding line line segment 36a-36h, and linear folding line is orientated two of extending to from upper limb 24 along diagonal line the lateral fold line segment 34a-34f and the vertical intersection of one of folding line line segment 32a-32f.For example, folding line line segment 36a extends to the intersection of

horizontal line segment

34a and 34b and vertical line segment 32a along diagonal line with the angle that is about 45 degree.It should be noted that (Fig. 2), between adjacent and at least one pair of folding line line segment of separating, closure member 14 is without any folding line line segment 36a-36h in folding line line segment 32a-32f.For example, do not have diagonal line folding line line segment between adjacent and a pair of folding line line segment 32c that separates and the 32d, thereby can form horizontal cap 38b.

Referring to Fig. 3, blank 20 is integral type blanks of being made in the mode of blank 16 by folding sheet material.Blank 20 comprises the part 50 that is roughly circle, is outward extended with a plurality of protrusions 52 from this part.In making container 10 processes, blank 20 is combined with blank 16, to form the container 10 that construct at unlimited top that is as shown in Figure 4, this provides and has led to the passage that container 10 in-to-ins open wide substantially, so that content is installed in the container.And the container 10 with the top of opening wide structure of Fig. 4 can be easily with a plurality of similar container stack, transport, store and distribute being used to, for example, in retail shop or fast food restaurant's environment.

In order to use container 10, the user will obtain to be the container of the structure that opens wide of Fig. 4, and fills this container by opening wide opening with the material of expecting (such as beverage).In this, desirably, container 10 can comprise mark (such as the interstitial wire by dotted line 54 expression), fills up height with the expectation of the container 10 pointing out to match with lid 14.Then, container 10 is configured to as Fig. 5-shown in Figure 8, lid 14 is formed as Fig. 1 and Fig. 7-sealing location and formation cap 38a-38b and 40a-40b shown in Figure 9 so that line segment 32a-32f, 34a-34f and 36a-36h are folded into.

Referring now to Fig. 5-Fig. 8,, shows the step that forms lid 14.From Fig. 5, turn up or fold sheet material around

crease line

32b and 32e at first, to limit the

triangular portion

54 and 56 that forms in abutting connection with gable by the opposite side that lays respectively at

crease line

32b and 32e of sheet material.

Then, as shown in Figure 6, the side of each

triangular portion

54 and 56 is shifted onto together and exerted pressure, with in folding towards each other

triangular portion

54 and 56 on the direction at the center of container 10.When promoting

triangular portion

54 and 56 each other, take place along remaining folding line line segment folding, the degree that the inferior horn up to as shown in Figure 7 each

triangular portion

54 and 56 is adjacent to each other.

Then, as shown in Figure 8, further promoting

triangular portion

54 and 56 abuts against each other respectively until the most
