Abstract

The utility model discloses a stretch cup, which consists of a plurality of layers of cup bodies (1) and a film layer (2), wherein the cup bodies (1) are arranged in the inner and the outer portions, the film layer (2) is made from non-toxic soft materials, the cup body (1) which is arranged in the inner layer can slide in the axial direction in an adjacent cup body (1) arranged in the outer layer, the bottom end of the cup body (1) arranged on the outermost layer is sealed, the upper end of the cup body (1) arranged on the outermost layer is opened, and the two ends of other cup bodies (1) are all opened. The upper portions of the inner walls of the other cup bodies (1) are all provided with ring-shaped grooves (3) beside the cup body (1) arranged on the innermost layer, the lower portions of the outer walls of the cup bodies (1) are all provided with ring-shaped bulges (4) which are matched with the ring-shaped grooves (3) beside the cup body (1) arranged on the outermost layer, the outer portion of the outer wall of the film layer (2) is bonded on the upper portion of the inner wall of the cup body (1) arranged on the innermost layer, and the bottom portion of the outer wall is bonded on the inner bottom surface of the cup body (1) arranged on the outermost layer. The stretch cup has the advantages of small volume and convenient carrying.

Description

A kind of telescopic cup

Technical field

The utility model relates to a kind of cup, is specifically related to a kind of cup of variable volume.

Background technology

Cup is the necessity that people live, in order to splendid attire boiling water, tea or beverage etc.Common cup all is to make an integral body, and as using at home or in the office, what inconvenience can not feel has in fixed place.And when people travel outdoors, for the purpose of health, usually can be with the cup of going up oneself, still because the volume of cup can not dwindle, shared space is bigger, carries just to seem very inconvenient.

The utility model content

The technical problem that the utility model will solve provides a kind of telescopic cup, and it is little that this cup has a volume, portable advantage.

The technical scheme that the utility model solves this technical problem is:

A kind of telescopic cup, this cup is formed by the multilayer cup of inside and outside setting and with the thin layer that nontoxic flexible material is processed, and the cup coupling that wherein is positioned at internal layer is at adjacent with it outer cup and can do at this skin cup and endwisely slip; Be positioned at the bottom end seal of outermost cup, the upper end is uncovered, the open at both ends of remaining cup; Except that the cup of innermost layer, the top of the inwall of all the other cups is equipped with annular groove; Except that outermost cup, the bottom of the outer wall of all the other cups is equipped with the annular protrusion that is complementary with described annular groove; Cup-shaped during described thin layer full extension formula, the top of its outer wall is bonded in the top of inwall of the cup of innermost layer, and the bottom adhesive of its outer wall is on the inner bottom surface of outermost cup.

The described telescopic cup of the utility model, wherein, the quantity of described cup is four.

The described telescopic cup of the utility model, wherein, the quantity of described cup is three.

The described telescopic cup of the utility model, wherein, the profile of described cup is truncated cone-shaped.

The described telescopic cup of the utility model, wherein, the height of described each cup equates.

The described telescopic cup of the utility model, because this cup is made up of the multilayer cup of inside and outside setting, and the cup that is positioned at internal layer can be done at adjacent with it outer cup and endwisely slips; Therefore, when needing to use, the cup that will be positioned at internal layer is pulled out, and makes that the annular protrusion between the adjacent cup sticks in the annular groove, and each layer cup combines and just formed cup like this; During carrying liquid, because thin layer is arranged, so the outside seepage of liquid that can not.When not in use, each layer cup is compressed together, and its shared volume has only the size of a cup.In addition, can also select to pull out the cup of varying number according to the difference of the amount of carrying liquid, thereby can change the volume of cup neatly.This shows that the cup of the utility model not only volume is little, be easy to carry, and use also very convenient.

The specific embodiment

Embodiment 1

Referring to Fig. 1～Fig. 3, the scalable cup of present embodiment constitutes by four plastics cups 1 of inside and outside setting with the thin layer 2 that nontoxic flexible material is processed, and wherein, the higher authorities of each cup 1 slightly inwardly shrink and form truncated cone-shaped, and the height of each cup 1 equates; Each is positioned at cup 1 coupling of internal layer at adjacent with it outer cup 1, and can in this skin cup 1, do and endwisely slip.In four cups 1, be positioned at the bottom seals of outermost cup 1, open topped, the two ends of remaining cup 1 are uncovered; Except that the cup that is positioned at innermost layer 1, the top of the inwall of its excess-three cup 1 is equipped with annular groove 3; Except that being positioned at outermost cup 1, the bottom of the outer wall of its excess-three cup 1 is equipped with the annular protrusion 4 that is complementary with above-mentioned annular groove 3.

Referring to Fig. 1 and Fig. 2, described thin layer 2 is located in the cup, and can stretch and fold, and is cup-shaped when its full extension; The top of the outer wall of thin layer 2 is bonded in the top of inwall of the cup 1 of innermost layer, and the mid portion of the bottom of the outer wall of thin layer 2 is bonded on the inner bottom surface of outermost cup 1.When each layer cup 1 pulled out, thin layer 2 was extended into cup-shaped, and to the liquid of wherein packing into, thin layer 2 can expand outwardly and be pressed on the inwall of cup 1; When 1 withdrawal of each layer cup, thin layer 2 is folded up in the cup 1 that places innermost layer.

Embodiment 2

Referring to Fig. 4, this enforcement is that with the difference of embodiment the cup 1 of the telescopic cup of present embodiment is three.

Certainly; Above-mentioned explanation is not to be the restriction to the utility model; The utility model also be not limited in above-mentioned for example, variation, remodeling, interpolation or replacement that the technical staff in present technique field is made in the essential scope of the utility model also should belong to the protection domain of the utility model.
