The crystal ball with seamless outer casing can effectively prevent filling liquids from leaking.

Description

The seamless housing of crystal ball

Technical field

The utility model relates to a kind of seamless housing of crystal ball, and the housing that refers in particular to a kind of crystal ball is the structural design of weldless seam.

Background technology

Existing crystal ball structure as shown in Figure 8, on a base 10, be installed with a transparent hollow ball 20, in this hollow ball 20, be filled with one or more ornaments 30, and be full of filling liquid 40 (for example water or oil) in inside, form a crystal ball, have unique visual effects ornament or ornaments, particularly under the correlating of light, can produce reflection and the dazzling effect that reflects.But the hollow ball 20 of existing crystal ball, normally transparent plastics are made, can the demoulding in order to make after the plastic shaping, hollow ball 20 must be divided into the other ejection formation of two half points, it is half ejection formation in a mould, second half is ejection formation in another mould, could take out from mould smoothly like this, and then with its butt joint combination, by ultrasonic hot melt or other fusion or bonding mode, make it form a complete hollow ball 20, so this hollow ball 20 can stay the seam 50 of one fusion or bonding, have influence on the aesthetic of crystal ball integral body.Especially be easy to generate faulty materials, wayward its quality, in brief, when these hollow ball 20 inside add filling liquid 40, carry out with fixed capacity under fixed temperature because be, when manufacturing was finished transportation or is sold to other area, heat rose or the effect of shrinkage because of variation of temperature takes place in meeting, thereby caused the inner bubble that produces, perhaps hollow ball 20 is held and be can't stand that internal pressure splits ease stream cruelly from seam 50, this shows that existing plastic crystal ball exists and demands improved shortcoming urgently.

The utility model content

At the problem that needs technology to exist, the purpose of this utility model is to provide a kind of seamless housing of crystal ball, the crystal ball surface of shell that plastics are made does not have seam fully, the filling liquid that can prevent enclosure interior is leaked, and promote crystal ball manufacturing and assembling efficiency, and effectively reduce its manufacturing cost.

The technical scheme in the invention for solving the technical problem is: a kind of seamless housing of crystal ball, the shell and the sealed piece that comprise clear hollow, one or more ornament and filling liquid are housed in this shell, described shell is that thermoplastic material is blown formation in mould, one end of shell is made as selected end, an opening arranged in that this selected end is one-body molded, described sealed piece covers on the described opening.

The seamless housing of described crystal ball, described shell are the geometry of rule.

The seamless housing of described crystal ball, described opening are a hollow tube, and this hollow tube is attached at the selected end of described shell, and this hollow tube communicates with the inside of described shell, and this sealed piece covers the end of hollow tube.

The seamless housing of described crystal ball, described sealed piece are a plastic foil, and this plastic foil covers on the opening of shell.

The seamless housing of described crystal ball, described sealed piece are a plastic foil, and plastic foil covers the end of hollow tube.

The seamless housing of described crystal ball, the outer wall of described hollow tube is provided with first screw thread; This sealed piece is the lid with a shrinkage pool, is provided with second screw thread at the shrinkage pool inwall, and second screw thread of this lid combines with first screw thread of hollow tube, makes lid cover the end of hollow tube.

The seamless housing of the crystal ball that the utility model passes through owing to adopt plastic blown to constitute, makes its structure not have seam fully, because needn't be engaged in the welding assembly working again, can full automation production, and effectively reduce the fraction defective of product; And when transporting, storing or playing, the situation of filling liquid from the seam seepage can not take place yet, and especially adopt PETG plastic material institute constitutors such as (PET), have more anti-effect of falling.

The specific embodiment

As shown in Figure 1 and Figure 2, the seamless housing of the utility model crystal ball, this seamless housing comprise that a shell 1 and a sealed piece 2 form, and can in shell 1, pack into an ornament 3 and filling liquid 4, wherein:

Shell 1, as Fig. 2, Fig. 3 and shown in Figure 4, be to adopt the made transparent ducted body of plastic material, it is made mode and blows in mould by thermoplastic material and constituted, on shell 1, set an end and be selected end, an opening 11 arranged in that selected end is one-body molded; Wherein, this thermoplastic material can be the thermoplastic material of polyvinyl (PE), polypropylene-base (PP), polyvinyl chloride-based (PVC), polystyrene-based (PS), PETG (PET) or the like.

Sealed piece 2, as Fig. 2, shown in Figure 3, it is and shell 1 same nature or the made plastic foil of plastics of different nature that this plastic foil is the opening that covers shell 1 11 that seals shape, and ornament 3 and filling liquid 4 in the shell 1 can not spilt;

Ornament 3 as shown in Figures 2 and 3, for being filled in the article in the shell 1, can be molded into various shapes with art or unique appearance, in its bottom in conjunction with a base 31, pack ornament 2 into shell 1 from opening 11 in, make base 31 clips at opening 11 places;

Filling liquid 4, for having the water or the oil of the transparency, pack shell 1 into from opening 11 in, can add paillette 41 to promote the visual effect of its decoration in this filling liquid 4;

This design team becomes the seamless housing of the utility model crystal ball.Because shell 1 adopts plastic blown to constitute, make its structure not have seam fully, needn't be engaged in the welding assembly working again, can full automation production, and effectively reduce the fraction defective of product, as shown in Figure 5, when it is produced shell 1 is stood upside down, insert filling liquid 4 and ornament 3, and then make sealed piece 2 cover the opening 11 of shell 1, this mode is easy to adopt automated machine to carry out this program and produces.

The seamless housing of the crystal ball that the utility model is made when transporting, storing or playing, because this sealed piece 2 is the rubber-like plastic foil, can bear the shrinkage heat effect that rises, and the situation of filling liquid from the seam seepage can not take place.And this shell 1 adopts PETG plastic materials such as (PET) to constitute, and has more anti-effect of falling.

In addition, as Fig. 1 and shown in Figure 8, shell 1 of the present utility model is blown in mould by thermoplastic material and is constituted, the problem of demoulding difficulty when not having the prior art ejection formation, this shell 1 can be blow molded into the geometry or the irregular shape of rule arbitrarily, for example spheroidal, ellipse, rectangle, polygonal cylindricality or the like, it is changeable to reach appearance easily, and the effect of product diversification.

As Fig. 2 and shown in Figure 4, the opening 11 of shell 1 can constitute a hollow tube 111, and this hollow tube 111 is attached at the selected end of shell 1, and this hollow tube communicates with the inside of shell 1, and this sealed piece 2 is the end 112 that a plastic foil covers hollow tube, reaches sealing function thus.But the mode that seals this opening 11 is not exceeded with the foregoing description, as Figure 6 and Figure 7, can be provided with one section first screw thread 113 at the outer wall of hollow tube 111, and this sealed piece 2 is embodied as the lid 21 with a shrinkage pool 22, inwall at shrinkage pool 22 is provided with one section second screw thread 23, and second screw thread 23 of this lid 21 combines with first screw thread 113 of hollow tube 111, makes lid 21 cover the end 112 of hollow tube 111, also can reach sealing effectiveness, form the seamless housing of a crystal ball.

More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
