Abstract

The utility model belongs to a gasket for packaging container and provides the gasket with grooves. The gasket in the prior art has the defects that when the gasket is sealed, substances when being heated in a container expand in volume, pressure in the container increases, the container expands to be broken and the substances in the container overflow in mild case, and the container even expands and blasts in serious case; when fermented objects are filled in the container, pressure in the container increases, microorganism of the fermented objects changes, and the fermented objects deteriorate; if fermented food is filled in the container, the fermented food deteriorates and can not be eaten. The gasket with the grooves is characterized in that the grooves (2) are arranged on one side of the gasket (1); one ends of the grooves (2) are arranged on edge of the gasket (1), the grooves (2) are 0.5 to 1 millimeter in depth, and the number of the grooves (2) is 1 to 3. The gasket with the grooves has the advantages that pressure inside and outside the container is ensured to be balanced, safety is ensured in temperature change and transportation, blast can be avoided, deterioration of the substances in the container can be prevented, and dust, rainwater and the like outside the container can not enter the container.

Description

Be with reeded pad

Technical field

The utility model belongs to the packing container pad, specifically is with reeded pad.

Background technology

Pad is widely used in various packing containers.Prior art is equipped with gasket seal in order to prevent that article in container are excessive and to leak outside in the lid of container.The advantage of gasket seal is: both can avoid article in container excessive and leak outside, can prevent again the material that container is outer, enter in container as dust, rainwater etc., guarantee the purity of material in container.The shortcoming of prior art is that container inner pressure increases when material in container meets that hot body is long-pending to expand, and the lighter produces that container bursts, material is excessive in container; Severe patient can produce the container expanding blasting; Also easily produce the chemical explosion of material in container, especially when container splendid attire hazardous materials, the consequence that blast produces is even more serious.When splendid attire in container fermented article, the pressure in container increased, and can cause that also the germ of fermentate changes, and made fermentate rotten; If fermented food causes food spoilage, can not eat.

Therefore in order to guarantee the safety of material in container and container, prevent exploding is dangerous, and what prevent that in container, the rotten a kind of container containing of invention of material uses is very necessary with reeded pad.

Summary of the invention

The purpose of this utility model is to provide the reeded pad of being with that a kind of splendid attire material container uses, and it is dangerous that this pad both can prevent exploding, can prevent that again in container, material is rotten, can also prevent that the outer dust of container, rainwater etc. from entering container.

The purpose of this utility model is achieved in that

The nanometer pad is provided with groove in the one side of pad, and an end of groove is located at the edge of pad.

The degree of depth of groove is 0.5-1 millimeter.

The quantity of groove is 1-3.

Main points of the present utility model are: the one side at pad is provided with 1-3 grooves, and an end of groove is located at the edge of pad, and the degree of depth of groove is 0.5-1 millimeter.

When the utility model pad uses, establish reeded one side, facing to the container lid inwall, do not have reeded one side, facing to internal tank.So, the gas in container forms passage by screw thread and the container external environment at groove and container lid edge.During greater than barometric pressure, the gas in container is by this passage amount discharge container when the pressure in container; During less than barometric pressure, the gas in atmosphere enters container by this passage when the pressure in container; Container internal and external pressure balance, container inner pressure can not raise, and can not form negative pressure yet, have guaranteed the safety of container.The passage that forms due to the screw thread at the groove of pad and container lid edge simultaneously is very little, prevented that the materials such as dust in the external environment and rainwater from entering in container, realized task of the present utility model and purpose.

The utility model pad can be applied to various containers, is particularly useful for the container of the various chemical substances of splendid attire and fermented food.

The utility model pad can be made with the various suitable materials of making pad, materials such as plastics, the scraps of paper, asbestos.

The utility model pad and container and lid coordinate, and make various diameters, size and style.

The utility model has the advantages that:

1. guarantee the container internal and external pressure balance, safety when temperature traverse and transportation, prevent exploding.

2. prevent that in container, material is rotten.

3. the dust outside container, rainwater etc. can not enter container.

Description of drawings

Fig. 1 is the utility model shim constructions figure.In figure, 1 is pad; 2 is groove.

The specific embodiment

Embodiment 1:

As shown in Figure 1: pad 1 is the composite material pad, is coated with one deck ptfe sheet on the EVA substrate, 10 centimetres of diameters.The EVA substrate of pad 1 simultaneously is provided with a groove 2, and an end of groove 2 is positioned at the middle part of pad 1, and an end is positioned at the edge of pad 1.The degree of depth of groove 2 is 0.5 millimeter, 3 centimetres of length.Establish reeded one side during use, facing to container lid, do not have reeded one side, facing to internal tank.

Embodiment 2:

Pad 1 is the EVA material, 5 centimetres of diameters.The one side of pad 1 is provided with two grooves 2, and an end of groove 2 is positioned at the middle part of pad 1, and an end is positioned at the edge of pad 1.The degree of depth of groove 2 is 1 millimeter, 2 centimetres of length.Establish reeded one side during use, facing to container lid, do not have reeded one side, facing to internal tank.

The above is only preferred embodiment of the present utility model, is not limited to the utility model, and for a person skilled in the art, the utility model can have change and change.All within spirit of the present utility model and principle, any modification of doing, improvement etc. are within all should being included in protection domain of the present utility model.

Claims

1. be with reeded pad for one kind, be comprised of pad (1), it is characterized in that: the one side at pad (1) is provided with groove (2), and an end of groove (2) is located at the edge of pad (1).
