Description

Sealed container structure

Technical Field

The present invention relates to a sealed container structure, and more particularly, to a sealed container structure for a container for holding volatile substances such as aromatic substances, deodorizers, and insecticides.

Background

The existing automobile aromatic, automobile deodorant, or indoor aromatic, indoor deodorant, insecticide and other products usually contain aromatic, deodorant or insecticide and other volatile substances in a packaging container, the packaging container is provided with an opening, and a sealing film is arranged at the opening to seal the opening, so that the volatile substances contained in the packaging container are prevented from volatilizing, and the storage and the transportation are facilitated.

Most sealing films of the existing volatile substance bearing containers are arranged at the openings of the containers in an adhering mode, when a user wants to use the volatile substance, the sealing films must be torn off from the openings of the bearing containers, and the volatile substance contained in the containers can volatilize into the air.

The existing volatile substance bearing and sealing container structure usually keeps a corner part not adhered to the bearing container, so that the non-adhered part of the sealing film is separated from the adhering surface of the bearing container, so that a user can firstly open the non-adhered part of the sealing film by fingers and then grasp the non-adhered part of the sealing film by the fingers during an operation procedure of tearing the sealing film, and further tear the whole sealing film from an opening of the bearing container.

However, in the conventional volatile substance container, to prevent leakage, only a small corner of the sealing film is left to be not attached to the opening attachment surface of the container, so that it takes a long time for an operator to find the non-attached portion of the sealing film. And the abutting surface of the opening of the container is usually adhered tightly, and the surface of the sealing membrane is usually smooth, so that when an operator grasps the non-abutting part of the sealing membrane by fingers to tear the sealing membrane, the operator takes a lot of effort, and the fingers are easy to slip, thereby causing the situation that the sealing membrane cannot be smoothly torn.

For the above reasons, the disadvantage that the sealing film of the conventional volatile substance container is not easy to tear off is caused, and how to solve the above problems by structural improvement has become one of the important problems to be solved in the art.

Detailed Description

As shown in fig. 1 and 2, the present invention provides a sealed container structure 1, which includes: a carrier 10, and a sealing membrane 20. In this embodiment, the carrying container 10 is made by injection molding of plastic material, the carrying container 10 has a container body 11, a bottom of the container body 11 is closed and an accommodating space is formed inside the container body 11 for accommodating a volatile substance 30, and a side of the container body 11 opposite to the bottom has an opening 15 for allowing the volatile substance 30 carried inside the container body 11 to contact with the outside air from the opening 15. The volatile substance 30 may be in a solid, liquid or gel state, and may be a type of volatile substance such as a fragrance, deodorant, insect repellent, mildew preventive, or the like. When the volatile substance 30 is contained in the container body 11, the opening 15 of the container body 11 can be sealed by the sealing film 20 to prevent the volatile substance 30 from being volatilized into the air.

The container body 11 is further provided with a gas permeable membrane 24 inside, and as shown in fig. 4, the gas permeable membrane 24 is provided inside the container body 11 at a position between the volatile substance 30 and the opening 15. The gas permeable membrane 24 is made of a gas permeable material (e.g., a non-woven fabric or a polymer or metal film material with dense pores), so that air and particles emitted from volatile substances can be allowed to pass through the gas permeable membrane 24.

The container body 11 is provided with a flange portion 12 at the periphery of the opening portion 15, the flange portion 12 extends from the side surface of the container body 11 located at the opening portion 15 to the direction away from the side surface of the container body 11, and an extending portion 13 is further connected to one side of the flange portion 12. In this embodiment, the extension portion 13 is a long rectangular bar having a width smaller than that of the flange portion 12, so that the extension portion 13 forms a grip portion connected to one side of the flange portion 12. The flange portion 12 forms a first abutting surface 121 with respect to one side surface of the container body 11, and the extending portion 13 forms a second abutting surface 131 with respect to one side surface of the container body 11, wherein the first abutting surface 121 and the second abutting surface 131 are aligned with each other on the same plane.

As shown in fig. 2 and 5, the carrier container 10 is provided with a partial cutting groove 14 at a position where the extension portion 13 and the flange portion 12 are connected, and the partial cutting groove 14 is linear and extends from one side to the other side where the extension portion 13 and the flange portion 12 are connected. As shown in fig. 4, the partial cutting groove 14 is located on a side surface opposite to the sealing film 20 from a position where the extension portion 13 and the flange portion 12 are connected, and the partial cutting groove 14 does not completely cut the material where the extension portion 13 and the flange portion 12 are connected, so that the extension portion 13 and the flange portion 12 remain connected, but the material thickness of the extension portion 13 and the flange portion 12 at a position of the partial cutting groove 14 is reduced, so that a user can easily break the extension portion 13 and the flange portion 12 from the position of the partial cutting groove 14, thereby forming a bending line 141 in the extension portion 13 and the flange portion 12 and the sealing film 20 at a position corresponding to the partial cutting groove 14.

The sealing film 20 is attached to the first attaching surface 121 and the second attaching surface 131 of the carrying container 10. in this embodiment, the sealing film 20 is made of a polymer film material, and the sealing film 20 forms a first portion 21 and a second portion 22 according to the shapes of the flange portion 12 and the extension portion 13 of the carrying container 10. The outline shape of the first portion 21 and the outline shape of the flange portion 12 are matched with each other, and the first portion 21 and the flange portion 12 can be attached to the first attaching surface and cover the opening 15 of the container body 11, so that when the first portion 21 of the sealing film 20 is attached to the first attaching surface 121, the opening 15 of the container body 11 can be sealed, and the volatile matter carried in the container body 11 is prevented from being volatilized and lost from the opening 15.

The shape of the second portion 22 of the sealing film 20 and the extension 13 are matched with each other and attached to the second attachment surface 131. As shown in fig. 5, since the sealing film 20 is attached on the surfaces of the extension portion 13 and the flange portion 12, when the operator bends the extension portion 13 upward from the position of the bending line 141, the first portion 21 and the second portion 22 of the sealing film 20 are also driven to bend with the bending line 141 as a boundary. Since the second portion 22 of the sealing film 20 and the first portion 21 are connected together, when the operator breaks the extension 13, the operator can further pull the second portion 22 of the sealing film 20 in a direction away from the container body 11, and can tear the first portion 21 of the sealing film 20 away from the first attachment surface 121 (as shown in fig. 8), thereby opening the opening 15 of the container body 11.

In order to achieve the aim of enabling the operator to easily and conveniently tear the sealing film 20 from the carrier container 10, the invention provides a score line 23 on the sealing film 20. As shown in fig. 3, the score line 23 is a dent formed on the surface of the sealing film 20 by pressurization and heating, and the score line 23 is provided on the surface of the sealing film 20 so as to be recessed in a direction from one side surface of the sealing film 20 with respect to the container body 11 toward the container body 11.

As shown in fig. 2 and 3, the carrying container 10 has a central axis C passing through from the center of the flange portion 12 of the container body 11 to the center of the tail end of the extension portion 13, the score line 23 is located at a position where the first portion 21 of the sealing film 20 is close to the bending line 141, and extends from one side of the first portion 21 of the sealing film 20 close to the bending line 141 to the other side. Meanwhile, the center of the score line 23 corresponding to the central axis C is bent toward the second portion 22 of the sealing film 20 to form a sharp projection 231, and the sharp projection 231 extends from the first portion 21 of the sealing film 20 toward the second portion 22 and protrudes from the bending line 141.

As shown in fig. 3, the end points of the score line 23 at both sides of the first portion 21 of the sealing film 20 are respectively defined as a first end point 232 and a second end point 233, and the pointed portion 231 is located between the first end point 232 and the second end point 233 and is aligned with the central axis C. A line segment between the first end point and the pointed projection 231 of the score line 23 is defined as a first line segment 23a, a line segment between the second end point and the pointed projection 231 of the score line 23 is defined as a second line segment 23b, and the first line segment 23a and the second line segment 23b of the score line 23 are symmetrical to the central axis.

The cusp portion 231 is connected between the first line segment 23a and the second line segment 23b, and the section where the cusp portion 231 is connected to the first line segment 23a and the second line segment 23b forms an arc-shaped line segment. Furthermore, the first line segment 23a and the second line segment 23b of the score line 23 are respectively obliquely disposed on the surface of the sealing film from the first end point 232 and the second end point 233 toward the central axis C and the direction of the bending line 141, so that the score line 23 forms a V-shaped line segment with a tip toward the second portion 22 of the sealing film 20.

In addition, as shown in fig. 2, a position of the second attachment surface 131 of the extension portion 13 close to the bending line 141 has a concave portion 132, and the shape and the position of the concave portion 132 and the protruding portion 231 of the pressing line 23 protruding from the bending line 141 correspond to each other. By the dent part 132, the adhesion force of the sealing film 20 and the extension 13 at the position of the pointed portion 231 can be further increased.

As shown in fig. 5 and 6, when the user intends to tear the sealing film 20 from the carrying container 10, the extending portion 13 of the container body 11 is first pulled by fingers to bend the extending portion 13 away from the container body 11, at which time the extending portion 13 and the flange portion 12 are bent and broken from the partial cutting groove 14, and the first portion 21 and the second portion 22 of the sealing film 20 are also bent at the bending line 141.

As shown in fig. 7, when the extension 13 and the second portion 22 of the sealing film 20 are bent at the partial cutting groove 14 and the bending line 141, the second portion 22 and the first portion 21 of the sealing film 20 are bent at the bending line 141, and the pointed portion 231 of the score line 23 is bent and deformed. Since the position of the score line 23 of the sealing film 20 is recessed, stress concentration occurs at the position of the score line 23 when the sealing film 20 is bent and deformed at the position of the score line 23. As shown in fig. 3 and 7, the pointed portion 231 of the score line 23 just crosses over the bending line 141, so that when the extension 13 and the second portion 22 of the sealing film 20 are bent and deformed at the position of the bending line 141, the pointed portion 231 of the score line 23 generates stress concentration, and the sealing film 20 located at the position of the pointed portion 231 is partially peeled off from the first bonding surface 121 and the second bonding surface 131.

As shown in fig. 8, the user can pull the second portion 22 of the sealing film 20 away from the bending line 141 to peel the first portion 21 of the sealing film 20 from the first attachment surface 121 of the flange 12. In this process, since the sealing film 20 of the pointed portion 231 of the score line 23 has been partially peeled off, in the process of the sealing film 20 being pulled to be torn off, since the sealing film 20 has been partially peeled off from the point of the pointed portion 231, the sealing film 20 is enabled to continue to expand the range of peeling from the partial peeling position of the pointed portion 231, so that the sealing film 20 can be easily torn off.

And when the first portion 21 of the sealing film 20 is continuously pulled in the direction opposite to the bending line 141, the position where the sealing film 20 and the first bonding surface 121 are peeled off is continuously diffused in the direction opposite to the bending line 141. As shown in fig. 3, the first line segment 23a and the second line segment 23b of the score line 23 of the present invention are arranged on the first portion 21 of the sealing film 20 in an inverted V shape, so that when the first portion 21 of the sealing film 20 is torn, the score line 23 also generates a stress concentration phenomenon, and the local peeling portion of the sealing film 20 at the pointed portion 231 gradually extends toward the first end point 232 and the second end point 233 along the first line segment 23a and the second line segment 23b of the score line 23.

Therefore, the present invention can make the seal film 20 peel locally at the sharp projection 231 of the score line 23 in advance during the tearing process of the seal film 20 by the stress concentration effect caused by the score line 23, so as to make the seal film 20 be easily torn after the completely and closely attached state of the seal film 20 is locally damaged, and can guide the local peeling position of the seal film 20 to gradually extend from the sharp projection 231 at the center of the score line 23 to the two sides of the seal film 20 along the score line 23 by the special shape of the score line 23, so that the tearing direction of the seal film 20 can be accurately controlled.

It is specifically noted that the sealing film 20 can be bounded by the score line 23 when it is attached to the container body 11, as shown in fig. 3, the sealing film 20 (i.e., the first portion 21) and the surface of the flange portion 12 that are shown above the score line 23 can be completely attached together to prevent the volatile material from leaking, while the sealing film 20 and the surface of the extension portion 13 and the flange portion 12 that are shown below the score line 23 can be detached from each other to facilitate the user's ability to tear the sealing film 20.

As shown in fig. 9 and 10, the sealed container structure 1 of the present invention is further combined with a fragrance container 40 to form an embodiment of a room fragrance device or a vehicle fragrance device. In this embodiment, the aromatic container 40 includes a base 41 and an upper cover 42, wherein the base 41 is recessed, a positioning portion 43 is disposed at the center of the base 41, and the shape of the positioning portion 43 and the shape of the container body 11 are matched to each other, so that the container body 11 can be fastened and fixed in the positioning portion 43. The upper cover 42 can cover the base 41 and cover the carrying container 10 thereunder. The upper cover 42 is provided with a plurality of ventilation holes 44, when the upper cover 42 is covered on the carrying container 10 and the user tears off the sealing film 20, the volatile substance 30 carried inside the container body 11 of the carrying container 10 can contact the outside air through the ventilation holes 44, so that the volatile substance 30 can be volatilized and diffused into the surrounding air. The upper cover 42 is further provided at the top end thereof with a holding member 45 for fixing the fragrance container 40 in a room or a vehicle interior.

As shown in fig. 9, when the carrying container 10 of the present invention is used with the fragrance container 40, a user can first break the extension 13 of the carrying container 10, the extension 13 and the second part 22 of the sealing film 20 are folded back to make the extension 13 and the second part of the sealing film 20 in a state of being flush with the surfaces of the flange part 12 and the first part 21 of the sealing film 20, then the container 10 with the folded extension 13 is placed into the base 41 of the fragrance container 40, and the cover 42 is closed, wherein the extension 13 of the container 10 and the second portion 22 of the sealing film 20 protrude from a side notch of the fragrance container 40 to the outside of the fragrance container 40, then, the user can tear the sealing film 20 off the flange portion 12 of the container body 11 by pulling the extension portion 13 in a direction away from the fragrance container 40, so that the volatile substance 30 in the container body 11 can be volatilized and diffused from the ventilation opening 44 of the upper cover 42 into the surrounding air.

As shown in fig. 11 and 12, the present invention is an example of a sealed container structure having another shape manufactured by the technique of the present invention. In the embodiment shown in fig. 11, the disclosed sealed container has an oblong container body 11, and the flange portion 12 and the sealing film 20 around the container body 11 are also matched to the shape of the container body 11 forming the oblong shape. As shown in fig. 12, the container body 11 and the sealing film 20 in this embodiment are also oblong, and the extension portion 13 connected to one side of the flange portion 12 is in the shape of a short circular arc.
