Abstract

The utility model relates to a cover for plastic drum and bottle, comprising an external cover, a cover body and an inner cover having a suspension link. A layer of thin plastic layer is provided between the inner cover having the suspension link and the cover body, the height of the inner cover is higher than the connecting ring of the cover body and the inner cover, and the connecting ring is the thin plastic layer. The structure adopted by the utility model excludes the effect of the thickness of the thin plastic layer which connects the cover body with the inner cover from injection moulding processes; thus, no matter how the pressure of an injection molding machine changes, the cover for plastic drum and bottle of the utility model avoids the phenomenon that the inner cover can not be opened because the suspension link can not be undrew or is pulled apart when the suspension link is pulled.

Description

The lid of Plastic Drum and bottle

Technical field

The utility model relates to the lid of Plastic Drum and bottle.

Background technology

Existing market is with the lid of the oil drum, particularly edible oil vessel of plastic production and bottle, and great majority are all by enclosing cover, lid body, is made up of the inner cap of draw ring, and the enclosing cover of outwarding winding during use utilizes draw ring to rip inner cap and gets final product being connected of body with covering.In the prior art since inner cap 3 and being connected of lid body 2 be one to enclose isoplanar very thin plastic layer, because the film that this circle is very thin forms in the gap of mould up and down by injection machine, so its thickness is difficult to control in manufacturing process, the die clearance was little when injection machine pressure was big, plastics are filled out discontented this gap, be easy to generate aperture, can occur during use leaking; Injection machine pressure hour die clearance is big, and the thin plastics thickness of generation is too thick, often have in actual use pull apart draw ring and the inner cap of not opening situation take place, as shown in Figure 3.

Summary of the invention

The technical problems to be solved in the utility model is the inner cap that overcomes Plastic Drum in the prior art and bottle with lid body bonded assembly plastic layer or because of the aperture that occurs in uneven thickness causes tearing draw ring and pulls not open inner cap or pull apart the do not open problem of inner cap of draw ring, provides the thin plastic layer of a kind of inner cap and body lid bonded assembly to stablize, evenly and easily open Plastic Drum and bottle cap.

For solving the problems of the technologies described above, the lid of the utility model Plastic Drum and bottle is connected as a single entity with the lid body, is made up of the inner cap of draw ring and the enclosing cover that cooperates with the lid body by the lid body that is enclosed within on Plastic Drum and the bottle.Enclosing cover and lid body are same as the prior art, it is characterized in that: the height of inner cap is higher than the promptly thin plastic layer of the clamping ring that covers body and inner cap.

The structure that the utility model adopted has been got rid of the influence of Shooting Technique to the thickness of thin plastic layer between connection cover body and the inner cap, and when the big and die clearance of injection machine pressure hour, the thin plastic layer of generation is that tubulose, thickness are constant; Big when injection machine pressure hour die clearance, the thin plastic layer of generation is the plane, and thickness still is constant.Therefore, no matter how injection machine pressure changes, and pulling not open or pulling apart draw ring and the phenomenon of the inner cap of not opening can not appear when tearing draw ring in the utility model Plastic Drum and bottle cap.

Description of drawings

Fig. 1 is the structural representation of the lid of prior art Plastic Drum and bottle.

1, enclosing cover; 2, lid body; The inner cap that 3, draw ring is arranged: 4, the promptly thin plastic layer of the clamping ring of lid body and inner cap.

Fig. 2 is the structural representation of the lid of the utility model Plastic Drum and bottle.

Fig. 3 is that inner cap and the thin plastic layer of lid between the body are the clamping ring connection diagram in the prior art.

3-1, mould are normal; 3-2, mould be pine partially; 3-3, mould are tight slightly.

Fig. 4 is that the thin plastic layer between the utility model inner cap and the lid body is the clamping ring connection diagram.

4-1, mould are normal; 4-2, mould be pine partially; 4-3, mould are tight slightly.

The specific embodiment

Describe in further detail below in conjunction with the lid of the drawings and the specific embodiments the utility model Plastic Drum and bottle.

In Fig. 2, enclosing cover is 1, and the lid body is 2, and the inner cap that draw ring is arranged is 3, and enclosing cover 1 is identical with the making of prior art, numerous stating not, and it is company's plastic that the inner cap 3 of draw ring and lid body 2 are arranged.Embodiment 1, when mould just often, as Fig. 4 (4-1): be higher than the end face that covers the body clamping ring at the bottom of the inner cap of the lid of the utility model Plastic Drum and bottle.Embodiment 2, when mould when pine partially, as Fig. 4 (4-2): the inner cap bottom surface of the lid of the utility model Plastic Drum and bottle and lid body bonded assembly end face are in one plane.Embodiment 3, when mould is tight slightly, as Fig. 4 (4-3): the inner cap bottom surface of the lid of the utility model Plastic Drum and bottle exceeds the more situation of body of covering.No matter because the utility model structure mould degree of tightness, this thin plastic layer is constant, so the Gai Buhui of the utility model Plastic Drum and bottle inner cap occurs pulling not open or pulls apart draw ring and the phenomenon of the inner cap of not opening.

Claims

1, the lid of charging basket and bottle, it is by the lid body that is enclosed within on Plastic Drum and the bottle, is connected as a single entity with the lid body and is made up of the inner cap of draw ring and the enclosing cover that cooperates with the lid body, and it is characterized in that: the height of inner cap is higher than the clamping ring that covers body and inner cap and promptly approaches plastic layer.

2, according to the lid of described Plastic Drum of claim 1 and bottle, it is characterized in that: the inner cap bottom surface is higher than the end face that covers the body clamping ring.

3, according to the lid of described Plastic Drum of claim 1 and bottle, it is characterized in that: the end face of inner cap bottom surface and lid body clamping ring in one plane.
